Published: April 2019

Objectives: The pathogenesis of hypertensive heart disease (HHD) remains unclear, which might include autoimmunity. The aim of the present study was to determine whether a relationship exists between the presence of autoantibodies against β1, β2, α1 adrenoreceptors, M2-muscarinic receptors, angiotensin II type1 receptors and HHD. Methods: In the present study, 44 patients diagnosed with HHD, 36 patients with hypertension, and 40 controls were also enrolled. The measurement of these 5 autoantibodies was performed by enzyme-linked immunosorbent assay. Results: The frequencies of autoantibodies against β1, β2, α1 adrenoreceptors, autoantibodies against M2-muscarinic receptors and autoantibodies against angiotensin II type1 receptors were significantly higher in patients with HHD, when compared to patients with hypertension and normal controls (all p < 0.001). In addition, the titers of these 5 autoantibodies significantly increased in patients with HHD. Patients who were positive for all 5 autoantibodies had larger left ventricular end-diastolic diameter (60.5 ± 4.9 vs. 57.8 ± 5.0 vs. 52.5 ± 5.3 mm) and worse left ventricular ejection fraction (45.0 ± 11.0 vs. 56.6 ± 10.4 vs. 57.8 ± 5.3%), when compared to patients not positive for all the 5 autoantibodies and patients negative for all the 5 autoantibodies (χ2 = 9.524, p = 0.009 and χ2 = 7.689, p = 0.021). Furthermore, a significant positive correlation was observed between each 2 autoantibodies of these 5 autoantibodies (all p < 0.001). Conclusion: Multiple autoantibodies of cardiovascular receptors may be involved in the pathogenesis and may be predictive factors of HHD.

Published: April 2019

Background: The etiology of congenital diaphragmatic hernia (CDH) remains poorly understood. We hypothesize that environmental factors play an important role in the development of CDH. Aim: The objective of this study was to investigate associated maternal risk factors in pregnancies with CDH. Material and Methods: The study was a nationwide, population-based prospective case-control study consisting of a cohort of newborn children entered into the records of pregnant women receiving antenatal care in Sweden, registered in the Medical Birth Registry during the period from January 1, 1982 to December 31, 2015. The study outcome CDH and the different exposures were assessed through linkage to the Swedish National Patient Registry for both cases and mothers. Results: A total of 972 cases of CDH were registered into one of the national registries in Sweden between 1982 and 2015. The incidence of neonates with CDH in Sweden from 1982 to 2015 was 3/10,000 live births. The mortality rate during the study period was 31%. Maternal age, ethnicity, parity, exposure to tobacco, BMI, IVF, previous history of spontaneous abortion or intrauterine fetal demise, and coexisting chronic diseases (urinary tract infection, chronic renal disease, pregestational diabetes, epilepsy, asthma, ulcerative colitis, inflammatory bowel disease, or systemic lupus erythematous) were not associated with an increased risk of CDH in the fetus. There was a significant association between maternal hypertension and the risk of the child being affected by CDH (OR 3.32, 95% CI 1.41–7.79, p = 0.01). No association was found between preeclampsia and CDH. Conclusions: Pregestational hypertension is associated with an increased risk of giving birth to a baby with CDH, but no association was observed in pregnancies developing preeclampsia and the occurrence of CDH.

Background: oXiris is a blood purification product that has been launched recently in China. In addition to renal function support and fluid management capabilities, it can also adsorb cytokines and endotoxins. This may complement standard treatment for septic acute kidney injury (AKI) patients to control the amplitude of systemic inflammatory response responsible for acute tissue and organ damage. Objectives of our study are to elucidate characteristics of septic AKI patients who respond to treatment with oXiris and to describe the performance of oXiris through patient cases in the absence of large randomized trials on clinical use of oXiris for septic AKI patients in China. Summary: Here, we present 4 cases managed in intensive care units of major hospitals in China. Key practical aspects from an expert meeting discussing these cases have been included as guidance for the use of oXiris in septic AKI patients. Key Messages: Based on the experience gathered from 4 cases, oXiris should be used early in the treatment of septic AKI patients as an adjuvant therapy with good infection source control. It should not be used to delay or replace infection source control. These cases also demonstrated that patients with high risk of bleeding can use oXiris without additional anticoagulation for up to 36 h without implications on serum protein levels and platelet count. Short of definitive biomarkers to gauge the ideal blood purification initiation and discontinuation time for septic AKI patients, clinical judgment is key to determining optimal use of oXiris in septic AKI patients.

The use of the oXiris® haemofilter during continuous veno-venous haemodiafiltration (CVVHDF) for acute kidney injury (AKI) and severe sepsis is not completely understood. Although this filter has in vitro adsorptive properties for blood-borne cytokines and other humoural mediators of sepsis, its clinical usefulness is uncertain. Given its inherent adsorptive limitation for septic mediators, we developed a CVVHDF protocol in which the oXiris haemofilter was electively changed every 12 h even though there was no clotting or adverse circuit pressures. Augmented filter membrane adsorption was conducted for 3 consecutive days. We treated a critically ill patient with severe sepsis secondary to a gram-negative bacterial infection and sepsis-associated acute kidney injury (SA- AKI) in this way. The patient required high-dose vasopressor support, required mechanical ventilation, had received 12 h of CVVHDF with conventional M100 haemofilter, was on broad spectrum antibiotics and other conventional intensive care unit (ICU) care, prior to institution of the frequent oXiris haemofilter change protocol. Following the start of elective 12 hourly oXiris filter change, the patient showed reduction in the need for vasopressor and by Day 4 of this SA- AKI frequent filter change protocol, vasopressor requirement ceased, he was extubated. He survived ICU and but not hospital stay. To this end, more clinical studies are needed.

Background: Chronic kidney disease (CKD) is a global public health problem and is linked to adverse outcomes during pregnancy; the high prevalence of CKD (3–6%) in women of childbearing age is of particular relevance in emerging countries where CKD prevalence is higher and resources are limited. Although CKD is a public health problem in Mexico, there is scant information on outcomes in pregnant CKD women in this country. We report maternal–fetal outcomes in a prospective cohort of poor, CKD pregnant women, and compare results with those of pregnant women without CKD. Methods: A prospective study of pregnant CKD women referred to a public obstetrics/nephrology clinic from July 2013 to December 2017; sociodemographic and clinical data, including complications and perinatal outcomes, were recorded. CKD was defined at referral as per KDIGO guidelines; preeclampsia and superimposed preeclampsia were defined as appearance or worsening of hypertension and proteinuria. Findings were compared to official data for ­Mexico and to a historic control of pregnant women without CKD who delivered at our hospital. Results: Sixty-two pregnancies in CKD patients, age 23.4 ± 5.8 years were observed; 46.8% of patients were primiparous. At referral, serum creatinine was 1.8 (1.1–3.0) mg/dL with an estimate glomerular filtration rate (eGFR) of 38.1 (21.9–68.0) mL/min/1.73 m2. In half of the cases, CKD was diagnosed during pregnancy. Forty-eight pregnant women without CKD, age 27 (22–34) years, who delivered during the study period were selected as controls: 33% were primiparous, serum creatinine was 0.50 (0.4–0.6) mg/dL, and estimate glomerular filtration rate was 135 (112–174) mL/min/1.73 m2. Twenty patients needed dialysis (HD-CKD): 2 were already on dialysis, and 18 began treatment during pregnancy; 42 CKD patients did not require dialysis (non-HD CKD). After delivery, 15 patients remained dialysis dependent while 5 did not. Preeclampsia was more frequent in CKD patients in comparison to controls. In total, 93% of CKD patients and 98% of controls delivered a live baby. Prematurity was more frequent in CKD patients than controls and was higher in HD-CKD than in non-HD CKD. Birth weight was lower in CKD when compared to controls. Logistic regression showed a higher risk of preeclampsia in CKD pregnancies than in controls, but it was not affected by age, parity, CKD stage, or need for dialysis during pregnancy. Conclusions: Underserved CKD Mexican women have a high rate of adverse maternal-fetal outcomes during pregnancy. The risk may be higher in patients needing dialysis during pregnancy, many of whom remained dialysis dependent after delivery.

Мета роботи: встановити види та частоту віддалених післяопераційних ускладнень, розвиток яких можна було б попередити, застосувавши способи та методи оперативного втручання у складі реконструкції аорто/клубово-стегно-підколінного артеріального русла.

Матеріали і методи. Прослідковано віддалені результати хірургічного лікування 491 пацієнта протягом 2006 – 2017 рр. Хірургічне втручання виконано 341 (69,4 %) пацієнту із атеросклеротичною оклюзією аорто-стегнової зони, з яких у 248 хворих мало місце порушення кровотоку по стегно-підколінному сегменті. Проведено операційне лікування у 150 (30,6 %) пацієнтів з приводу оклюзивно-стенотичного ураження клубово-стегнового сегмента, з яких у 94 мало місце порушення кровотоку по стегно-підколінному артеріальному руслі. У 92 (18,7 %) пацієнтів діагностовано гемодинамічно значимий стеноз екстракраніальних артерій, з них у 75 хворим було проведено операційне втручання на судинах шиї в умовах хірургічного лікування атеросклеротичного ураження аорто/клубово-стегно-підколінного артеріального русла.

Результати досліджень та їх обговорення. Після 491 реконструктивного операційного втручання на аорто/клубово-стегно-підколінному артеріальному руслі у віддаленому післяопераційному періоді діагностовано 139 (28,3 %) пізніх ускладнень. Серед них у 42 (30,9 %) пацієнтів розвинувся пізній тромбоз бранші аорто/клубово-біфеморального алопротеза та пізній тромбоз клубово-стегнового сегмента контрлатеральної нижньої кінцівки, у 11 (7,9 %) пацієнтів діагностовано несправжні аневризми дистального та проксимального анастомозів аорто/клубово-біфеморального алошунта, у 78 (56,1 %) встановлено наростання хронічної ішемії нижніх кінцівок (ХАН ІІІА-Б ст. за класифікацією Fontaine R. з врахуванням критеріїв Європейської робочої групи (1992)), у 8 (5,8 %) – пізні інфекційні ускладнення у вигляді нориці ділянки дистального анастомозу.

Розвиток таких пізніх ускладнень, як тромбоз клубово-стегнового сегмента (6 спостережень) контрлатеральної нижньої кінцівки; пізній тромбоз однієї з бранш аорто-біфеморального алошунта (5 спостережень) в результаті блокування оклюзивним процесом анастомозів ПАС і ГАС із низхідною артерією коліна, підколінною артерією та гомілковими артеріями; несправжня аневризма проксимального анастомозу (2 спостереження) аорто-біфеморального алошунта як результат формування анастомозу в межах обмеженого кровопостачання країв серединного аортотомічного розрізу, чому можна запобігти застосувавши способи та методи операційного втручання у складі аорто/клубово-біфеморального алошунтування.

За наявності гемодинамічно значимого атеросклеротичного стенозу екстракраніальних артерій у пацієнтів із атеросклеротичною оклюзією аорто/клубово-стегно-підколінного артеріального русла необхідно провести операційне втручання на судинах шиї до або одночасно із хірургічним втручанням на аорто/клубово-стегно-підколінній зоні.

Published: April 2019

Мета роботи: покращити результати лікування хворих на низхідний гнійний медіастиніт шляхом удосконалення хірургічних доступів до середостіння, методів місцевого хірургічного лікування.

Матеріали і методи. Проведено обстеження та лікування 170 хворих із низькими флегмонами шиї (ФШ), які перебували знаходилися на лікуванні у відділені торакальної хірургії Івано-Франківської обласної клінічної лікарні з 2000 до 2018 р. Серед хворих у 53 (31,2%) ФШ ускладнилася розвитком НГМ. Серед 53 хворих чоловіків було 34 (64,2 %), жінок − 19 (35,8 %), віком від 21 до 72 років, у середньому вік хворих становив (41,3 ± 3,9) року.

Результати досліджень та їх обговорення. Хірургічне лікування НГМ передбачає усунення первинного джерела захворювання, вибір операційного доступу до середостіння, розкриття всіх гнійних ділянок та їх санацію, забезпечення постійного видалення гнійних мас із клітковини середостіння. Для попередження поширення ФШ у клітковину середостіння ми застосовували оригінальну методику інтрамедіастинального введення антибактеріальних середників (ІМВА). При застосуванні ІМВА нам вдалося знизити частоту розвитку НГМ із 50,7 до 9,1 % випадків. У 10 (20,8 %) хворих ми провели додаткове розкриття медіастинальної плеври верхнього середостіння за допомогою відеоасистованої торакоскопії (ВАТС). Використання ВАТС в хірургічному лікуванні НГМ дозволяє провести повноцінний огляд медіастинальної плеври та середостіння, дозволяє ефективно розкрити та санувати всі уражені ділянки середостіння та провести їх адекватне дренування. При застосування хірургічніх втручань на випередження поширення гнійного процесу у середостінні нам вдалося знизити кількість повторних оперативних втручань із 45,3 до 3,7 %.

Наведено приклад використання малоінвазивних методів лікування – ортоніксія (3ТО, титанова нитка, L-вкладка, ARKADA) при лікуванні оніхокріптозу (врослого нігтя). Малоінвазивні ортоніксичні методи застосовували на базі Київської міської клінічної лікарні № 6 протягом 2012-2018 рр. Досягнуто повне відновлення нігтьової пластини і усунення вростання нігтьових пластин при малоінвазивному ортоніксичному втручанні. Лікування врослого нігтя стає більш ефективним. Дані методики усувають недоліки інших систем і оперативних методик, оскільки одночасно діє на два патогенетичні фактори, а саме на нігтьову пластину, моделюючи її подальше зростання, і на нігтьові валики, формуючи їх анатомічно під фізіологічну форму нігтьової пластини. Спираючись на клінічний досвід лікарів Київської міської клінічної лікарні № 6 та співробітників кафедри загальної та невідкладної хірургії НМАПО імені П. Л. Шупика, можна сказати, що дані методики можуть застосовуватися в клінічній практиці лікарів України.

Hospital Incidence and In‐Hospital Mortality of Surgically and Interventionally Treated Aortic Dissections: Secondary Data Analysis of the Nationwide German Diagnosis‐Related Group Statistics From 2006 to 2014
Authors: Reutersberg Benedikt , Salvermoser Michael , Trenner Matthias , Geisbüsch Sarah , Zimmermann Alexander , Eckstein Hans‐Henning , Kuehnl Andreas
Published: April 2019

Background

Population‐based data about the incidence and mortality of patients with aortic dissections (
ADs
) are sparse. Therefore, the hospital incidence and in‐hospital mortality of patients undergoing open or endovascular surgery for type A
ADs
(
TAADs
) and type B
ADs
(
TBADs
) in Germany were analyzed on a nationwide basis between 2006 and 2014.

Methods and Results

A secondary data analysis of the nationwide diagnosis‐related group statistics, compiled by the German Federal Statistical Office, was performed for patients who were surgically/interventionally treated for
AD
(
International Classification of Diseases, Tenth Revision, German Modification
[

ICD
‐10‐

GM
]

codes I71.00‐I71.07; n=20 533). By using specific procedure codes, a distinction between
TAAD
(n=14 911/72.6%) and
TBAD
(n=5622/27.4%) could be made. The standardized hospital incidence of surgically/interventionally treated
AD
was 2.7/100 000 per year, comprising 2.0/100 000 per year for
TAAD
and 0.7/100 000 per year for
TBAD
. The in‐hospital mortality of
TAAD
was 19.5%; and of
TBAD,
9.3%. Both the incidence and in‐hospital mortality increased over the 9‐year period. The share of endovascularly treated
TBAD
increased steadily during the same time interval. A multilevel multivariable analysis revealed that, for
TAAD
, age and comorbidity were significantly associated with a higher mortality risk.

The latter was also true for
TBAD
. Sex was not significantly associated with mortality. A significant association between higher annual center volume and mortality was found for
TAAD
, but not for
TBAD
.

Conclusions

This is the first report on hospital incidence and mortality for surgically/interventionally treated
AD
on a nationwide basis. Overall, in Germany, hospital incidence and mortality of
TAAD
and
TBAD
increased over time. In addition,
TAAD
is performed more safely in high‐volume centers.

Published: April 2019

Apogonalia nielsoni, a new cicadelline leafhopper species from Mexico (Nayarit State), is described and illustrated. The color pattern of the new species is similar to that of A. germana (Fowler), whereas the male genital characteristics are similar to those of A. monticola (Fowler). The aedeagal shaft of A. nielsoni has a pair of short, triangular lateral processes that are absent in A. monticola. The paraphyses in both species are formed by a curved, Y-shaped basal plate and by a pair of narrow and very long rami. Apogonalia nielsoni has the arms of the basal plate longer than those of A. monticola. Moreover, the rami of the new species are dorsally or ventrally curved, whereas in the latter species they are approximately straight.

A new anchialine shrimp of the genus Procaris from Christmas Island: the first occurrence of the Procarididae in the Indian Ocean (Crustacea: Decapoda: Caridea)
Authors: BRUCE A. J. , DAVIE P. J.F.
Published: April 2019

A fifth species of the anchialine shrimp genus Procaris is described from Christmas Island, northeast Indian Ocean. This marks the first record of the Procarididae from the Indian Ocean. The closest known congeneric species, and the only other known from the Indo-West Pacific region, is P. hawaiiana Holthuis, 1973, from Hawaii. The new species can be separated from other described species by its angular fifth abdominal pleuron, having the medial eye lobe longer than the lateral, and by having a distolateral tooth on the scaphocerite. A cladistic analysis suggests the new species is sister to the clade containing the Pacific, P. hawaiiana, and the Atlantic P. chacei.

Published: April 2019

Material recently collected from the Solomon Islands include three species of Acanthaxius Sakai & de Saint Laurent, 1989, two of which are new to science: A. clevai n. sp. and A. gadaletae n. sp. and a specimen of A. polyacantha Miyake & Sakai, 1967. Two specimens from New Caledonia are assigned to A. gadaletae n. sp. The new taxa are readily differentiated from A. polyacantha by their longer rostrum and the glabrous postcervical region of carapace. A. clevai n. sp. is characterized by a slender rostrum longer than the eyestalks, with two lateral and a suborbital spine, the gastric region with a median, submedian and lateral carina, setose pereopods 1 with three and two upper spines on the propodal palm and dactylus respectively, the telson longer than broad with three teeth and one spinule on the lateral border. A. gadaletae n. sp. is similar to A. clevai n. sp. but differs by the gastric region with two submedian carinae, the pereopod 1 with four upper spines both on the propodal palm and the dactylus, the maxilliped 3 basis with a large lower distal spine (absent in A. clevai n. sp.) and the abdominal pleura 3–5 with an anterior spinule (absent in A. clevai n. sp.).Trois espèces d’Acanthaxius Sakai & de Saint Laurent, 1989, dont deux nouvelles, des Iles Salomon et de Nouvelle Calédonie (Crustacea, Thalassinidea, Axiidae).

Because P. koelreuteriae is a significant pest species that damages the ornamental and medicinal plants of the genus Koelreuteria, notes on its biology, host plants and distribution are presented.
Estimating the Role of SST in Atmospheric Surface Wind Variability over the Tropical Atlantic and Pacific
Authors: Richter Ingo , Doi Takeshi
Published: April 2019

The influence of sea surface temperature (SST) on interannual surface wind variability in the tropical Atlantic and Pacific is estimated using sensitivity experiments with the SINTEX-F GCM and the ensemble spread in a nine-member control simulation. Two additional estimates are derived for both SINTEX-F and the ERA-Interim reanalysis using regression analysis and singular value decomposition. All methods yield quite consistent estimates of the fraction of surface wind variability that is determined by SST and therefore potentially predictable. In the equatorial Atlantic, analysis suggests that for the period 1982–2014 approximately 2/3 of surface zonal wind variability in boreal spring and early summer is potentially predictable, while 1/3 is due to noise. Of the predictable component, up to about 35% may be driven from outside the tropical Atlantic, suggesting an important role for remote forcing and a diminished one for local feedbacks. In the northern tropical Atlantic, only 30% of boreal winter variability is predictable, most of which is forced from the Pacific. This suggests a minor role for local coupled air–sea feedbacks. For the equatorial Pacific, the results suggest high predictability throughout the year, most of which is due to local SST, with the tropical Atlantic only playing a minor role in boreal summer. In the tropical Atlantic, atmospheric internal variability is strongly dependent on the presence of deep convection, which, in turn, is related to mean SST. A similar, but weaker, state dependence of internal variability is evident in the tropical Pacific.

Published: April 2019

This paper presents thickness-weighted averaging (TWA) in generalized vertical coordinates as a unified framework for a variety of existing tidal-averaging concepts in seas and estuaries. Vertical profiles of resulting residual quantities depend on the specific vertical coordinate, which is held fixed during the averaging process. This dependence is demonstrated through the application to one-dimensional analytical tidal flow with sediment transport, to field observations from a tidal channel, and to model results from a two-dimensional estuary. The use of different coordinate systems provides complementary views on the residual dynamics and stresses the importance of a correct interpretation of residual quantities obtained by tidal averaging.
Computation of Optimal Weights for Solving the Atmospheric Source Term Estimation Problem
Authors: Turbelin Grégory , Singh Sarvesh , Issartel Jean Pierre , Busch Xavier , Kumar Pramod
Published: April 2019

In case of a release of a hazardous material (e.g., a chemical or a biological agent) in the atmosphere, estimation of the source from concentration observations (provided by a network of sensors) is a challenging inverse problem known as the atmospheric source term estimation (STE) problem. This study emphasizes a method, known in the literature as the renormalization inversion technique, for addressing this problem. This method provides a solution that has been interpreted as a weighted minimal norm solution and can be computed in terms of a generalized inverse of the sensitivity matrix of the sensors. This inverse is constructed by using an appropriate diagonal weight matrix whose components fulfill the so-called renormalizing conditions. The main contribution of this paper is that it proposes a new compact algorithm (it requires less than 15 lines of MATLAB code) to obtain, in a fast and efficient way, those optimal weights. To show that the algorithm, based on the properties of the resolution matrix, matches the requirements of emergency situations, analysis of the computational complexity and memory requirements is included. Some numerical experiments are also reported to show the efficiency of the algorithm.
A Hybrid Stochastically Perturbed Parametrization Scheme in a Convection-Permitting Ensemble
Authors: Wastl Clemens , Wang Yong , Atencia Aitor , Wittmann Christoph
Published: April 2019

Model error in ensemble prediction systems is often represented by either a tendency perturbation approach or a process-based parameter perturbation scheme. In this paper a novel hybrid stochastically perturbed parameterization (HSPP) scheme is proposed and implemented in the Convection Permitting Limited Area Ensemble Forecasting (C-LAEF) system developed at the Zentralanstalt für Meteorologie und Geodynamik (ZAMG). In HSPP, the individual parameterization tendencies of the physical processes radiation, shallow convection, and microphysics are perturbed stochastically by a spatially and temporally varying pattern. Uncertainties in the turbulence scheme are considered by perturbing key parameters on the process level. The proposed scheme HSPP features several advantages compared to the popular stochastically perturbed parameterization tendencies (SPPT) scheme: it considers a more physically consistent relationship between different parameterization schemes, deals with uncertainties especially adapted to the individual physical processes, respects conservation laws of energy and moisture, and eliminates the tapering function that has to be introduced to the SPPT scheme because of mainly numerical reasons. The hybrid scheme HSPP is evaluated over one summer and one winter month and compared to a reference ensemble without any stochastic physics perturbations and to two versions of the SPPT scheme. The results show that HSPP significantly increases the ensemble spread of temperature, humidity, wind speed, and pressure, especially in the lower levels of the atmosphere where a tapering function is active in the original SPPT approach. Precipitation verification yields a generally improved probabilistic performance of the HSPP scheme in summer when convection is dominating, which has also been demonstrated in a case study.

Published: April 2019

Background

Abnormalities of iron metabolism in pregnancy pose risks for maternal and fetal health. Robust reference intervals for iron metabolism indices have not been established in a pregnant Chinese population. The purpose of this study was to derive reference intervals for indices of iron metabolism during pregnancy in a Chinese population.

Methods

A total of 360 healthy pregnant women were recruited and divided into three groups of 120 by gestational age: first trimester (1–13 weeks), second trimester (14–27 weeks) and third trimester (≥28 weeks). An additional 120 healthy non-pregnant women were recruited as the non-pregnant control group. Serum ferritin was measured by electrochemiluminescence immunoassay. Serum iron and total iron-binding capacity were measured by a direct bathophenanthroline method. Transferrin saturation value was calculated with formula TS = SI/TIBC. The reference intervals were established using a non-parametric method.

Results

In first and second trimesters (combined), the reference intervals for serum ferritin, serum iron, total iron-binding capacity and transferrin saturation are 14.7–184.3 mg/L, 14.50–33.45 µmol/L, 36.53–68.81 µmol/L and 19.04–64.76%, respectively. In the third trimester, the reference intervals for serum ferritin, serum iron, total iron-binding capacity and transferrin saturation are 7.2–122.2 mg/L, 5.83–21.52 µmol/L, 49.40–122.76 µmol/L and 8.22–52.75%, respectively.

Conclusion

The reference intervals for iron metabolism indices for healthy pregnant Chinese women were established in accordance with CLSI C28-A3 guidelines. This will be a valuable tool for clinical practice and research.
Comparing the Robustness of Stepwise Mixture Modeling With Continuous Nonnormal Distal Outcomes
Authors: Shin Myungho , No Unkyung , Hong Sehee
Published: April 2019

The present study aims to compare the robustness under various conditions of latent class analysis mixture modeling approaches that deal with auxiliary distal outcomes. Monte Carlo simulations were employed to test the performance of four approaches recommended by previous simulation studies: maximum likelihood (ML) assuming homoskedasticity (ML_E), ML assuming heteroskedasticity (ML_U), BCH, and LTB. For all investigated simulation conditions, the BCH approach yielded the most unbiased estimates of class-specific distal outcome means. This study has implications for researchers looking to apply recommended latent class analysis mixture modeling approaches in that nonnormality, which has been not fully considered in previous studies, was taken into account to address the distributional form of distal outcomes.
When onboarding becomes risky: Extending social learning theory to explain newcomers’ adoption of heavy drinking with clients
Authors: Liu Songqi , Bamberger Peter , Wang Mo , Shi Junqi , Bacharach Samuel B
Published: April 2019

What drives newcomers to adopt behaviors that, while perhaps helping them meet short-term role demands and organizational objectives, may also place themselves and/or their organization at risk in the long term? Based on social learning theory, research on onboarding and newcomer socialization suggests that such behavior may be explained by peer modeling. But is this always the case? Using heavy drinking with clients as an empirical referent and incorporating factors from research on learning in risky choice into a model grounded on social learning theory, we examine how contextual variables moderate the effect of veteran peer modeling on newcomer adoption or intensification of work-related risky behaviors over time, and demonstrate the impact of adoption/intensification on newcomer outcomes. Data from a longitudinal study of newcomers, their veteran peers, and supervisors in sales and client-service indicate that the extent to which veteran modeling influences the adoption/intensification of newcomer heavy drinking with clients depends on newcomers’ prior experiences and veteran peer (but not supervisor) guidance. Moreover, they indicate that steeper increases in heavy drinking with clients over time, while associated with improved job performance, also link to higher work-to-family conflict and turnover risk. Implications for research on onboarding and newcomer socialization are discussed.
Mental health issues among indigenous communities and the role of traditional medicine
Authors: Cianconi Paolo , Lesmana Cokorda Bagus Jaya , Ventriglio Antonio , Janiri Luigi
Published: April 2019

Introduction:

Mental health in indigenous communities is a relevant issue for the World Health Organization (WHO). These communities are supposed to live in a pure, clean and intact environment. Their real condition is far different from the imaginary; they are vulnerable populations living in difficult areas, exposed to pollution, located far from the health services, exposed to several market operations conducted to extract natural resources, facing criminal groups or illegal exploitation of land resources. These factors may have an impact on mental health of indigenous population.

Methods:

We reviewed all papers available on PubMed, EMBASE and The Cochrane Library until December 2018. We focused on those factors affecting the changes from a traditional to a post-modern society and reviewed data available on stress-related issues, mental distress affecting indigenous/aboriginal communities and the role of Traditional Medicine (TM). We reviewed articles from different countries hosting indigenous communities.

Results:

The incidence of mental distress and related phenomena (e.g. collective suicide, alcoholism and violence) among indigenous populations is affected by political and socio-economic variables. The mental health of these populations is poorly studied and described even if mental illness indicators are somewhat alarming. TM still seems to have a role in supporting affected people and may reduce deficiencies due to poor access to medical insurance/coverage, psychiatry and psychotherapy. It would be helpful to combine TM and modern medicine in a healthcare model to face indigenous populations’ health needs.

Conclusion:

This review confirms the impact of societal changes, environmental threats and exploitation of natural resources on the mental health of indigenous populations. Global Mental Health needs to deal with the health needs of indigenous populations as well as psychiatry needs to develop new categories to describe psychopathology related to social variance as recently proposed by the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5).
Teaching about the Korean Ganggangsullae Folk Tradition in General Music Class
Authors: Yi Gina J.
Published: April 2019

Korean folk music has been rarely included in the Western music curriculum due to limited materials for music teachers to use. This article introduces Ganggangsullae, a prominent Korean folk tradition (called a “folk play” by Koreans) that incorporates singing and dancing, and discusses its historical background and the unique elements of Korean folk music that it illuminates: Korean rhythm, minyo singing, dancing, and dialogue play. In addition, this article offers practical teaching guidance for incorporating Ganggangsullae into the elementary general music classroom.
The Tanglewood Symposium: Popular Music Pedagogy from 1967 to Today
Authors: Gurgel Ruth
Published: April 2019

The Tanglewood Symposium of 1967 is an event now looked back on as a watershed moment in the field of music education. At the Symposium, societal happenings of the day provided the background for the discussions, including the Civil Rights movement and the explosion of rock’n’roll. At the Symposium, members held important conversations about popular music and the future of music education. This article analyzes the documentation surrounding the Symposium and suggests areas of music education that still remain a part of the hidden curriculum supporting inequity and how these areas can be brought to light and addressed in popular music pedagogy today.
Utilization of Property Among African American Heir and Titled Landowners in Alabama’s Black Belt
Authors: Baba Akon , Zabawa Robert , Zekeri Andrew
Published: April 2019

Much of the literature on heir property, or land held in common by heirs without the benefit of a will, deals with its widespread existence, consequences, and problems associated with it in the Southern Black Belt. Little is known about the uses of this property compared with titled property among African American landowners. We address this research gap by using survey data to examine uses of heir and titled properties among African Americans landowners in rural Alabama. Findings indicate that majority of the titled landowners used their land more productively and invest more money in their land than do heir property owners. There is also a higher financial value for titled land than heir property. Heir property owners take more of a short-term and limited financial investment plan that includes annual production of crops and livestock, as well as leases for hunting. Titled property owners, however, take a long-term plan for their land that includes timber, investments in buildings and land, and participation in the United States Department of Agriculture (USDA) conservation programs.
Point-wise model validation over experimental regions using regression confidence and tolerance intervals with Bayesian relaxations
Authors: Storm Scott M , Hill Raymond R , Pignatiello Joseph J , White Edward D , Vining G Geoffrey
Published: April 2019

As systems grow more complex, so does our propensity to use computers to emulate complex real-world systems. Often these real-world systems possess dynamic response behavior over the operational domain of input parameter configurations. This domain is referred to as the design space or experimental region. It is critical we ensure that computer models which emulate such dynamic behavior be validated over the full design space. This paper presents a dual-interval validation methodology. Confidence intervals and tolerance intervals are developed based on a system response surface function. Model samples are compared to each interval to develop a complete model validation conclusion. The methodology is described, its robustness to noise and model lack-of-fit examined, and then it is applied to a well-established engineering validation challenge problem.
What Factors Influenced Turkish Military Officers’ and NCOs’ Motivation to Serve Prior to the July 2016 Coup Attempt?
Authors: Aydiner Cihan , Orak Ugur , Solakoglu Ozgur
Published: April 2019

Motivation is a key factor for the military institution to accomplish its goals. Extant academic research, however, has generally focused on the combat motivation and the motivation to serve has been understudied. This study examines the motivation to serve and its predictors among Turkish military officers and NCOs. The aim of the current study is 2-fold: (1) to test the effectiveness of measures proposed by previous studies in Turkish Armed Forces and (2) to build on the existing body of knowledge by showing the impacts of perceived fairness and satisfaction with social benefits. Survey data, which were conducted only 2 months before the coup attempt in Turkey on July 15, 2016, were used to assess the motivation. Findings revealed that institutional and moral commitments, organizational responsiveness, perceived fairness, and satisfaction with social benefits were positive significant determinants of motivation to serve, while occupational commitment had a negative relationship with it.
Airway Malformations and Bronchiectasis: A Pediatric Study
Authors: Dosanjh Amrita
Published: April 2019

Congenital airway malformations are most often identified in early childhood. The development of bronchiectasis in association with malformations of the lower airway has been described, particularly among adult patients. The coexistence in a pediatric population of these conditions is not well described. This study was conducted to identify whether younger patients with airway malformations commonly develop bronchiectasis. International Classification of Diseases, Ninth revision (ICD-9 codes) were defined for airway anomalies and bronchiectasis. The electronic medical records system of a children’s hospital was then searched for the number of patients with upper airway anomalies with or without bronchiectasis. The airway database was then cross referenced with the ICD codes for bronchiectasis to identify patients with both conditions. There were 844 patients with airway anomalies and 117 with bronchiectasis in the electronic system during the time period of August 1, 2009 to September 30, 2014. There was only 3 patients identified with both bronchiectasis and airway anomalies. The coexistence of bronchiectasis is low among the pediatric population with upper airway anomalies studied. This would suggest that the children with airway anomalies have been treated with strategies that are effective in the prevention of recurrent lower respiratory tract infection. Further study may be done to define the effectiveness of various strategies in preventing aspiration and lower respiratory tract infection. In addition, this methodologic technique utilizing database integrative platforms is useful in the identification of patients for further study and to identify the coexistence of pediatric conditions.
