Lullabies and preterm infants: A contribution to the study of infant-directed singing in the NICU

The practice of singing to babies has been observed around the world, in all cultures and historical periods. In cases of prematurity, benefits of maternal singing have been reported for both the baby and maternal anxiety levels. Therefore, several authors have expressed concerns about the possible decrease in singing practice for the infant and, consequently, the loss of transmission of children’s oral repertoire. In this study, our purpose was to understand what and how do mothers sing to their babies, in the specific case of hospitalized pre-term infants in a Portuguese NICU. We used a mixt method in a study case where 36 mothers sang without words to their hospitalized preterm infants during Kangaroo Care. We parametrized the repertoire and analyzed its characteristics, namely the melodic contours, range pitch, melodic intervals, rhythm, tempo and form. The participants also responded to a questionnaire regarding the habits of singing to their baby. Older and more educated mothers sang more pre-existent melodies and younger mothers tended to improvise. This study showed that the former mothers tend to sing adult songs and children's mediated songs to their hospitalized babies more than traditional Portuguese play songs or lullabies suggesting that mothers are not familiar with the Portuguese repertoire, as shown in other studies. It is possible that the sociological changes Portuguese families, as well as the development of automatic reproduction devices that replace mother’s voice, led to this fact. The latter mothers’ improvised singing was highly repetitive and mostly by whole tones. These characteristics, maybe related to an attempt to please and calm the baby, were also common to a comfortable chant for a female voice without practice.
Corporate Governance and Corporate Social Responsibility: Evidence from the Role of the Largest Institutional Blockholders in the Korean Market

This study investigates the monitoring effectiveness of the largest institutional blockholder in Korea, the Korean National Pension Service (KNPS), on firms’ engagement in corporate social responsibility (CSR). We use a large, unique sample from Korea, where the financial market is primarily characterized by chaebols. We show that lagged KNPS blockholdings do not significantly influence investee firms’ concurrent CSR indexes. This result indicates that even the largest institutional blockholder in Korea does not actively engage in firms’ CSR initiatives to enhance their long-term performance and prosperity. Overall, our results suggest that institutional investors should more actively serve as an effective corporate governance mechanism in emerging Asian markets, where companies aim to be profitable and long-term corporate governance is very important.
Dexmedetomidine in supraclavicular block: Effects on quality of block and analgesia

Context and Objectives: Upper limb surgeries are most commonly performed under brachial plexus block (BPB). A variety of adjuvants have been used to enhance the effect of local anesthetics in peripheral nerve block. We evaluated the effect of dexmedetomidine as an adjuvant to 0.25% bupivacaine in supraclavicular block (SCB) in terms of onset and duration of sensory and motor block, analgesia, and quality of block. Subjects and Methods: Sixty American Society of Anesthesiologists physical status I and II patients undergoing upper limb surgery, in which SCB was used, were enrolled. Patients were assigned to one of the following groups alternatively: Group C received BPB with bupivacaine 0.25% (34 ml) + normal saline 1 ml. Group D received BPB with bupivacaine 0.25% (34 ml) + dexmedetomidine 1 μg/kg. Onset and duration of sensory and motor block, duration of analgesia, sedation score, and hemodynamic parameters were studied in both the groups. Results: There were no significant differences in patient and surgery characteristics between two groups. In Group D, shorter time to onset of sensory block (09.8 vs. 15.3 min, P = 0.006) and longer duration (691.3 vs. 395.6 min, P = 0.006) was observed. Onset time to achieve motor block (11.8 vs. 17.3 min, P = 0.009) was also short and duration was longer (637 vs. 367.6 min, P< 0.001) in Group D. Duration of analgesia (735.6 vs. 423.6 min, P< 0.001) was higher as compared to control group. Conclusions: Adding dexmedetomidine to bupivacaine during supraclavicular BPB shortens sensory and motor block onset time, increases the sensory and motor block duration, and prolongs the duration of postoperative analgesia without any significant side effect.
Can Ecological Interactions be Inferred from Spatial Data?

The characterisation and quantication of ecological interactions, and the construction of species distributions and their associated ecological niches, is of fundamental theoretical and practical importance. In this paper we give an overview of a Bayesian inference framework, developed over the last 10 years, which, using spatial data, offers a general formalism within which ecological interactions may be characterised and quantied. Interactions are identied through deviations of the spatial distribution of co-occurrences of spatial variables relative to a benchmark for the non-interacting system, and based on a statistical ensemble of spatial cells. The formalism allows for the integration of both biotic and abiotic factors of arbitrary resolution. We concentrate on the conceptual and mathematical underpinnings of the formalism, showing how, using the Naive Bayes approximation, it can be used to not only compare and contrast the relative contribution from each variable, but also to construct species distributions and niches based on arbitrary variable type. We show how the formalism can be used to quantify confounding and therefore help disentangle the complex causal chains that are present in ecosystems. We also show species distributions and their associated niches can be used to infer standard "micro" ecological interactions, such as predation and parasitism. We present several representative use cases that validate our framework, both in terms of being consistent with present knowledge of a set of known interactions, as well as making and validating predictions about new, previously unknown interactions in the case of zoonoses.
Spin Transition of Iron in δ‐(Al,Fe)OOH Induces Thermal Anomalies in Earth's Lower Mantle

Seismic anomalies observed in Earth's deep mantle are conventionally considered to be associated with thermal and compositional anomalies, and possibly partial melt of major lower‐mantle phases. However, through deep water cycle, impacts of hydrous minerals on geophysical observables and on the deep mantle thermal state and geodynamics remain poorly understood. Here we precisely measured thermal conductivity of δ‐(Al,Fe)OOH, an important water‐carrying mineral in Earth's deep interior, to lowermost mantle pressures at room temperature. The thermal conductivity varies drastically by twofold to threefold across the spin transition of iron, resulting in an exceptionally low thermal conductivity at the lowermost mantle conditions. As δ‐(Al,Fe)OOH is transported to the lowermost mantle, its exceptionally low thermal conductivity may serve as a local thermal insulator, promoting high‐temperature anomalies and the formation of partial melt and thermal plumes at the base of the mantle, strongly influencing thermo‐chemical profiles in the region and fate of Earth's deep water cycle.
Effect of early peritoneal drainage on the injury of intestinal mucosa in the rats with severe acute pancreatitis

Objective To study the protective effect of early peritoneal drainage against injury of intestinal mucosa in rats with severe acute pancreatitis. Methods Thirty-six SD rats were randomly and equally divided into three group, i.e. control group, model (SAP) group, drainage (APD) group. Severe acute pancreatitis was induced in rats by injecting 5% sodium taurocholate (2ml/h, 0.1ml/100g) into the common biliopancreatic duct. All the rats were sacrificed 24 hours after operation. The condition of abdominal cavity was observed, and pathological changes in ileum were detected by HE staining. The serum levels of TNF-α, IL-1β, diamine oxidase (DAO) and D-lactate were determined by ELISA. Results Compared with the control group, the histopathological changes in ileum were more marked, and serum levels of TNF-α, IL-1β, DAO and D-lactate were significantly higher in SAP group and APD group (P<0.05); Compared with SAP group, the histopathological changes in ileum were less marked, and serum levels of TNF-α, IL-1β, DAO and D-lactate were significantly lower in APD group (P<0.05). Conclusion Early peritoneal drainage can effectively improve the intestinal mucosal injury in acute pancreatitis rats, and reduce the systemic inflammatory response.

Efecto de un extensor de grasa sobre algunas propiedades de calidad de un chorizo tipo antioqueño

Desde la Universidad Nacional de Colombia Sede Medellin, con el proposito de desarrollar un producto carnico bajo en grasa, se estudio el efecto de dos extensores grasos sobre las propiedades de calidad de un chorizo tipo antioqueno. Se reemplazo la grasa en dos niveles (70 % y 100 %) por grasa extendida al 50 %. El primer extensor (E1) se elaboro a partir de tocino dorsal de cerdo mas una mezcla de alginato de sodio, sulfato de calcio y pirofosfato tetrasodico, desde donde se obtienen los tratamientos A y B; el segundo, contenia la misma mezcla anterior mas fibra citrica, desde donde se obtienen los tratamientos C y D. Los chorizos elaborados con ambos extensores fueron comparados con un chorizo formulado a partir de tocino de cerdo. A cada muestra obtenida se le analizaron las perdidas por purga (sineresis en el empaque), la calidad sensorial y la fuerza de corte. Los datos obtenidos en las diferentes determinaciones fueron analizados estadisticamente mediante analisis de varianza de una via (ANOVA), con un nivel de significancia de 0,05. En las pruebas realizadas para determinar las perdidas por purga no se hallaron diferencias significativas. Respecto al analisis sensorial en terminos de olor, sabor, color, dureza, apariencia interna y apariencia externa, se evidenciaron diferencias significativas (p0,05) entre algunos tratamientos. Con relacion a la fuerza de corte se mostraron diferencias significativas (p0,05) unicamente con el tratamiento B, formulado a partir del primer extensor empleado y con un reemplazo de grasa del 100 % por grasa extendida, para el cual la fuerza de corte siempre fue mayor; siendo este, en general, el tratamiento con mejor desempeno
Estrogen receptor β and estrogen receptor α36 predict differential outcome of patients with breast cancer

Background: Clinical management of breast cancer is guided by assessment of tumor parameters, including histological features and biomarkers. Estrogen receptors alpha (ERα) and beta (ERβ) are involved in the carcinogenesis and progression of breast cancer. Among the ERs, ERα66, the main type of ERα, is one of the most powerful indictors for molecular classification, treatment and prognosis of breast cancer, while the clinical significance of ERβ in breast cancer is elusive. Moreover, ERα36, a variant of ERα66, has recently been identified as an important molecule involved in breast cancer progression, but the clinical relevance of its expression in breast cancer needs to be further clarified. Therefore, this study is aimed to evaluate the prognostic value of ERβ and ERα36 in human breast cancer. Methods: We examined ERβ and ERα36 expression in breast cancer specimens from 124 patients with complete followed-up by immunohistochemistry. To assess the prognostic values, we generated disease-free survival (DFS) curves by Kaplan-Meier method and performed multivariate analysis by Cox proportional hazard regression model. Results: An inverse correlation between ERβ and ERα36 expression was observed (r=−0.196, P=0.029). The expression of ERβ was inversely associated with lymph node metastasis (P=0.007), whereas ERα36 expression was positively correlated with TNM stage (P=0.006) and tumor size (P=0.026). Patients with ERβ-positive exhibited better DFS rate than those with ERβ-negative (P=0.019). Conversely, patients with ERα36-positive exhibited poorer DFS rate than those with ERα36-negative (P=0.047). ERβ-negative/ERα36-positive patients had the poorest DFS rate (P=0.014). Cox regression analysis showed that ERβ was a protective prognostic factor (HR=0.336, P=0.026), and ERα36 was a poor prognostic indicator (HR=2.737, P=0.029). Conclusions: Our results suggest that both ERβ and ERα36 can act as the prognostic indictors and the combination of the two indictors has a better prognostic value for breast cancer.
Yoga: Can it be integrated with treatment of neuropathic pain?

Background: Neuropathic pain (NP) is a debilitating condition that may result from spinal cord injury (SCI). Nearly 75% of all SCIs result in NP affecting 17,000 new individuals in the United States every year, and an estimated 7-10% of people worldwide. It is caused by damaged or dysfunctional nerve fibers sending aberrant signals to pain centers in the central nervous system causing severe pain that affects daily life and routine. The mechanisms underlying NP are not fully understood, making treatment difficult. Identification of specific molecular pathways that are involved in pain syndromes and finding effective treatments has become a major priority in current SCI research. Yoga has therapeutic applications that may prove beneficial in treating subjects suffering chronically from SCI-induced NP, chronic back and associated pain if necessary experimental data are generated. Summary: This review aims to discuss the implications of various mechanistic approaches of yoga which can be tested by new study designs around various nociceptive molecules including matrix metalloproteinases, cation-dependent chloride transporter (NKCC1), etc. in SCI-induced NP patients. Key Messages: Yogic practices could be used in managing SCI-induced NP pain by regulating the action of various mechanisms and its associated molecules. Modern prescriptive treatment strategies combined with alternative approaches like yoga should be used in rehabilitation centers and clinics in order to ameliorate chronic NP. We recommend practical considerations of careful yoga practice as part of an integrative medicine approach for NP associated with SCI.
A Classification of Sleep Disorders with Optimal Features Using Machine Learning Techniques

Background: Sleep disorders become one of the early warnings of potential Non-Communicable Diseases (NCDs). Polysomnography (PSG) or sleep test is a formal method to diagnose sleep disorders. However, the PSG is limited in many hospitals due to its high costs. It also requires various sensors attached to a patient, which may cause inconvenience. Moreover, trained sleep specialists are required to interpret the gigantic PSG data. Researchers attempt to identify sleep disorders using alternative techniques. Method: This study proposed an alternative technique for sleep-related syndrome and sleep disorder classification with optimal features. Patient PSG datasets were retrieved from a hospital in the south of Thailand. In the data preprocessing stage, the datasets were analyzed and normalized using feature extraction and selection mechanisms. Optimal feature selection using the average information gain values was evaluated with the 10-fold cross validation. Four Machine Learning (ML) techniques, k MC, k NN, SVM and MLP, were used in our experiments. The selected ML techniques have been performed and evaluated with the 10-fold cross validation in data preprocessing and model construction phases. Results: The k NN achieved the highest overall classification results. The optimal features with k NN ( opf - k NN) was proposed. The selected features were PULSE, SAO2, CANR and CHEST. With the selected optimal features, only the ordinary oxygen oximeter and the ECG machine were required. Overall classification result of the opf-k NN achieved at 95.17%±3.91. Conclusion: Although the PSG is the formal sleep disorder diagnosis, alternative diagnostic techniques are beneficial especially to patients. Our study proposed the opf - k NN technique to classify sleep disorders with two concerns, the limited access to high-priced medical equipment and patient comfortability. Finally, sleep specialists also obtain benefits in optimizing bio-signal interpretations with only four optimal features.
Investigation of complex permittivity spectra of foundry sands

Abstract This paper discusses impedance spectroscopy as a method to characterize different types of quartz sand, chromite sand, and mixtures of sand. Based on two types of measurement cells, the impedance spectra for various dry sands were measured. The spectra differ enough to allow the sands to be distinguished. The results were validated by extracting the relative permittivity from the impedance and comparing it to literature data. After that, the method could be applied with confidence to other material systems. The influence of moisture was investigated with two types of quartz sand, and typical mixtures of form sand, chromite sand, and regenerated (quartz) sand were studied. In each case, the sand composition had a distinct influence on the Nyquist plot of the impedance spectrum. Compared to results from a laboratory foundry system, the new method exhibits a much more systematic dependence on the sand composition. If one succeeds in describing the impedance spectra with an equivalent circuit model parameterized by only a few parameters, these parameters could be used to identify and classify sand mixtures in the field. This would allow one, for example, to implement feedback control strategies in foundry regeneration processes, which would stabilize the processes and improve the quality of the casting products.
Introducing Macro-Financial Variables into a Semi-Structural Model

This paper outlines a flexible and consistent model-based framework suitable for forecasting selected macro-financial variables of the Czech economy and conducting policy analysis to support the decision-making process. We enhance an existing semi-structural model of the Czech economy in order to replicate some of the characteristics of the financial cycle, i.e. co-movement between credit and house prices, higher persistence of respective macro-financial variables and a pronounced impact of shocks on the business cycle.
Closing the Wearable Gap—Part IV: 3D Motion Capture Cameras Versus Soft Robotic Sensors Comparison of Gait Movement Assessment

The purpose of this study was to use 3D motion capture and stretchable soft robotic sensors (SRS) to collect foot-ankle movement on participants performing walking gait cycles on flat and sloped surfaces. The primary aim was to assess differences between 3D motion capture and a new SRS-based wearable solution. Given the complex nature of using a linear solution to accurately quantify the movement of triaxial joints during a dynamic gait movement, 20 participants performing multiple walking trials were measured. The participant gait data was then upscaled (for the SRS), time-aligned (based on right heel strikes), and smoothed using filtering methods. A multivariate linear model was developed to assess goodness-of-fit based on mean absolute error (MAE; 1.54), root mean square error (RMSE; 1.96), and absolute R2 (R2; 0.854). Two and three SRS combinations were evaluated to determine if similar fit scores could be achieved using fewer sensors. Inversion (based on MAE and RMSE) and plantar flexion (based on R2) sensor removal provided second-best fit scores. Given that the scores indicate a high level of fit, with further development, an SRS-based wearable solution has the potential to measure motion during gait- based tasks with the accuracy of a 3D motion capture system.

Telemedicine and the Pediatric Tertiary Care Center

Telemedicine is broadly defined as the use of electronic communication and information technologies to provide or support clinical care at a distance. As such, telemedicine is not new to the practice of medicine, especially from the perspective of a tertiary care referral center. One can readily appreciate that the use of the telephone and fax machine in the support of clinical care meets this definition with familiar tools the medical community has accepted and incorporated for some time.

Applying self-determination theory to exploring students' perception towards learning modes of service-learning

This research applied self-determination theory (SDT) to investigating undergraduate students’ perceptions of the effectiveness of blended-learning approach in equipping them with the necessary skills to cope with international service-learning, in the aspects of autonomy, relatedness and competences. Qualitative research in form of focus groups was adopted to collect students’ opinions about blended-learning activities, and comparative analysis was used to discern their manifested and latent views in relation to competence, relatedness and autonomy. Results showed that the students perceived having been well-equipped with the competences and skills required for the service delivery through the blended-learning activities. They also perceived that their relatedness and autonomy have been enhanced, which resulted in better preparation to face uncertainties in the service trip. It is suggested that teachers, researchers and administrators could contemplate how to fine-tune blendedlearning activities to better integrate into the service-learning class for students’ learning facilitation.
