Published: January 2019

Background. Human Pappilloma Virus (HPV) is the necessary cause of cervical cancer. A number of risk factors are believed to influence the role of HPV in the development of cervical cancer. This is so because majority of HPV infections are cleared and only a few are able to result into cancer. Chlamydia trachomatis (CT) is considered a potential cofactor in the development of cervical intraepithelial neoplasia (CIN), although different studies have produced contradicting information (Silins et al., 2005, Bellaminutti et al., 2014, and Bhatla et al., 2013). The objective of this cross-sectional study was to determine the prevalence and association of HPV-Chlamydial coinfection with cervical intraepithelial lesions and other risk factors for cervical intraepithelial lesions at a hospital in south western Uganda (MRRH). Methods. The study included 93 participants, with an age range of 25 to 80 years, from whom cervical specimens were collected and enrolment forms were completed upon consent. Experienced midwives collected one cervical smear and two endocervical swabs from each participant. The swabs were used for HPV DNA and Chlamydia trachomatis antigen testing. Data was entered in Microsoft excel and analysed using STATA 12 software. With the help of spearman’s correlation at the 0.05 level of significance, bivariate and multivariate analysis were done by logistic regression, to determine associations of risk factors to cervical lesions. Results. The results showed the prevalence of HPV-Chlamydial coinfection to be 8.6% (8/93). Positive Pap smear results were found in 60.22% (56/93) participants, most of whom had low grade squamous intraepitherial lesion (LSIL) (54.84%). HPV-Chlamydial coinfection showed a significant correlation with a positive cytology result and only relatively significantly correlated with LSIL grade of cytological positivity. HPV was found to be the risk factors associated with cervical intraepithelial lesions at MRRH. Conclusion. HPV, Chlamydia, and HPV-Chlamydial coinfection are prevalent infections and there is a likelihood of association between HPV-Chlamydial coinfection and with cervical intraepithelial lesions. This study recommends general sexually transimitted infections (STIS) screening for every woman that turns up for cervical cancer screening and a larger study, probably a multicentre study.
Ectopic Papillary Carcinoma in the Midline Neck Accompanied by a Benign Thyroid Gland
Authors: Evans Lauran , Park SeHoon , Elliott Christie , Garrett Courtney
Published: January 2019

Ectopic thyroid tissue can deposit anywhere in the body. There are several cases reporting papillary thyroid carcinoma (PTC) arising from ectopic tissues; however, these cases largely presented with primary PTC within the native thyroid gland as well. Alternatively, some cases report of PTC found solely in an ectopic thyroglossal duct cyst, but reports of isolated malignancy in other types of ectopic thyroid tissue with normal native tissue are sparse throughout the literature. Here, we present an unusual case of PTC in the midline anterior neck that does not appear to be consistent with a thyroglossal duct cyst, accompanied by a completely benign native thyroid gland, of which only few cases have been reported.
Cost-Effectiveness of the Aerobika® Oscillating Positive Expiratory Pressure Device in the Management of Chronic Obstructive Pulmonary Disease Exacerbations in Canada
Authors: Thanh Nguyen Xuan , Jacobs Philip , Suggett Jason , McIvor Andrew , Kaplan Alan
Published: January 2019

Background. The Aerobika® oscillating positive expiratory pressure (OPEP) device is a hand-held, drug-free medical device that has been shown to improve lung function and improve health-related quality of life in patients with chronic obstructive pulmonary disease (COPD). We estimated the cost-effectiveness of this device among postexacerbation COPD patients in the Canadian healthcare system. Methods. We performed a cost-utility analysis using a Markov model to compare both costs and outcome of patients with COPD who had recently experienced an exacerbation between 2 treatment arms: patients who used the Aerobika® device and patients who did not use the Aerobika® device. This cost-utility analysis included costs based on the Alberta healthcare system perspective as these represent Canadian experience. A one-year horizon with 12 monthly cycles was used. Results. For a patient after 1 year, the use of the Aerobika® device would save $694 in healthcare costs and produce 0.04 more in quality-adjusted life years (QALYs) in comparison with no positive expiratory pressure (PEP)/OPEP therapy. In other words, the economic outcome of the device was dominant (i.e., more effective and less costly). The probability for this device to be the dominant strategy was 72%. With a willingness to pay (WTP) threshold of $50,000 per QALY gained, the probability for the Aerobika® device to be cost-effective was 77%. Conclusions. Given one of the major treatment goals in the GOLD guidelines is to minimize the negative impact of exacerbations and prevent re-exacerbations, the Aerobika® OPEP device should be viewed as a potential component of a treatment strategy to improve symptom control and reduce the risk of re-exacerbations in patients with COPD.

Objective. Moxibustion is a complementary therapy that has been used for thousands of years. Burning moxa produces smoke and inhalable particulates. Recent research has indicated that smoke inhalation is associated with negative lung effects. This study aimed to evaluate the lung function of rats after moxa smoke exposure at different concentrations. Methods. Using a randomised block experiment design, 28 male Wistar rats were randomly divided into three moxa smoke groups (opacity) (n=7): low concentration (27.45 mg/m3), medium concentration (168.76 mg/m3), and high concentration (384.67 mg/m3) with a control group. Rats in the moxa smoke groups were exposed in an automatic dynamic exposure device separately with different concentrations for 20 min/d, 6d/week, for 24 weeks. Rats in the control group were exposed in the same space without moxa smoke. Lung function was evaluated by the AniRes 2005 animal pulmonary function analysing system. Statistical Product and Service Solutions 18.0 software was used for data analysis. Results. In the study, no deaths were found in any group. There was no difference of forced expiratory volume in one second/forced vital capacity percentage (FEV1/FVC%), inspiratory resistance (Ri), and expiratory resistance (Re) among each group after 24 weeks of moxa smoke exposure (P>0.05). Compared with the control group (0.33 ml/cmH20), dynamic compliance (Cdyn) was reduced in the medium (0.29 ml/cmH20) and high (0.25 ml/cmH20) concentration groups (P<0.05); however, Cdyn in the low concentration group (0.29 ml/cmH20) was not significantly affected. Conclusion. Moxa smoke exposure at low concentrations did not affect the rat’s lung function. Moxa smoke of medium and high concentrations destroyed the lung function represented by decreased Cdyn. However, moxa smoke of low concentrations (27.45 mg/m3) is much higher than the concentration in a regular moxibustion clinic (3.54 mg/m3). Moxa smoke at higher concentrations might destroy the lung function. The safety evaluation of moxa smoke requires further research.

Internet of things (IoT) is realized by the idea of free flow of information amongst various low-power embedded devices that use the Internet to communicate with one another. It is predicted that the IoT will be widely deployed and will find applicability in various domains of life. Demands of IoT have lately attracted huge attention, and organizations are excited about the business value of the data that will be generated by deploying such networks. On the contrary, IoT has various security and privacy concerns for the end users that limit its proliferation. In this paper, we have identified, categorized, and discussed various security challenges and state-of-the-art efforts to resolve these challenges.

Published: January 2019

Background. Pituitary metastasis of cervical adenocarcinoma is an exceedingly rare phenomenon. Case Description. The authors present a case of a 66-year-old female with cervical adenocarcinoma who was discovered to have a rapidly growing intrasellar mass in the work-up of adrenal insufficiency and hypothyroidism. The patient underwent subsequent endoscopic endonasal subtotal resection of the mass. Histopathological analysis of the resected lesion demonstrated features consistent with metastatic mucinous adenocarcinoma of the cervix. While initially neurologically asymptomatic following surgery, the patient developed an oculomotor nerve palsy several weeks following surgical debulking, at which time neuroimaging revealed marked regrowth and suprasellar extension of the metastatic lesion. Conclusions. While metastatic cervical adenocarcinoma to the sella is rare, it should be considered in the differential based on the history of the patient.

Objective: To explore the effectiveness and safety of round window niche drilling combined with intratympanic methylprednisolone injection for the salvage treatment of sudden sensorineural hearing loss (SSNHL) and its associated tinnitus after failed primary treatment. Method: SSNHL patients who showed a less than 10-dB improvement of pure-tone average after receiving standard systemic treatment and intratympanic steroid injection were enrolled. All included patients were randomly divided into two groups (control and study). Patients in the study group received round window niche drilling combined with daily intratympanic methylprednisolone for 7 times; the control group received only daily intratympanic methylprednisolone for 7 times. One month after treatment, the improvements of PTA, speech discrimination score (SDS), tinnitus and the incidence of adverse events were analyzed. Results: 20 patients (10 for each group) were included in this study. The baseline between two groups showed no statistical significance. Patients in the study group experienced an average hearing improvement of 20.38 dB, SDS 19.3 compared with 2.1 dB and SDS 2.0 in the control group. None (0%) in the control group and 4 patients (40%) showed marked recovery, 5 patients (50%) showed slight improvement of hearing in the study group after 1 month. All patients in the study group showed significant recovery of tinnitus. Both tinnitus handicap inventory and a symptom visual analogue scale between two groups revealed statistical differences (p < 0.001, p = 0.002, respectively). None in the control and study groups experienced vertigo, infection and facial paralysis. Conclusion: Round window niche drilling increases the contact area and time of methylprednisolone. It is an effective and safe salvage therapy of idiopathic SSNHL and its induced tinnitus.
When Calcium Gets Tough, the Tough Cardiologist Starts to Play …

Published: January 2019

Coronary calcification is a hard challenge for the interventional cardiologist, as it is associated with incomplete stent expansion and frequently stent failure. In recent years, innovative techniques, such as rotational atherectomy, have been developed to treat coronary calcification. However, these are burdened with an increased procedural risk. We report the case of a 60-year-old Caucasian man treated 1 month before at another center with primary coronary angioplasty and stenting of the ramus intermedius for coronary syndrome. Coronary angiography showed a critical stenosis of the left main coronary artery as well as critical calcified stenosis of the left anterior descending artery and the diagonal branch. Coronary calcification was treated with rotational atherectomy that preceded the angioplasty and stenting. Because of persistence of the symptomatology, coronary angiography was repeated 1 month later and showed a critical calcified restenosis of the ramus intermedius at the site of the previous stenting. Considering the high risk of traditional atherectomy, we performed lithotripsy-enhanced disruption of calcium beyond the stents with the Shockwave Coronary Lithoplasty System. The Shockwave Coronary Lithoplasty System has been introduced recently in order to treat calcified coronary lesions with greater safety. The procedure allows most calcified coronary lesions to be treated with simplicity and safety. This system employs sound waves, similar to those used for treating kidney stones, to crush the calcified lesions. We present the first case described to date in whom this technique was successfully used to treat calcified restenosis in a previous stent.

Authors: Shah Jamil , Patel Kalpesh , Sunkara Tagore , Papafragkakis Charilaos , Shahidullah Abul
Published: January 2019

Background: Gastric diverticula (GD) are outpouchings of the stomach wall that typically form in the fundus. They are the least common gastrointestinal diverticula, and are very rare anatomic abnormalities overall. Summary: Although most GD are asymptomatic and are usually discovered incidentally during routine diagnostic testing, they can present with variable symptoms. Occasionally, complications can develop that may be life-threatening and are indications for surgical management. Key Messages: Here, we provide a literature review of GD where we discuss the pathogenesis, clinical manifestations, investigations and diagnostic approach, and various management options for this uncommon disorder.

Objective: To investigate the origin and outcome in a cohort of male and female fetuses with intra-abdominal cysts, in order to provide recommendations on management and to improve prenatal counselling. Methods: From 2002 to 2016, intra-abdominal cysts were detected by ultrasound in 158 fetuses. Cases with an umbilical vein varix were excluded. Fetal, neonatal, and maternal characteristics were retrieved from electronic patient files. Results: In female fetuses (n = 114), intra-abdominal cysts were diagnosed at a later gestational age compared with male fetuses (n = 44) (median 32.0 vs. 21.5 weeks, p < 0.001). The maximum prenatal cyst diameter was larger in female fetuses (median 35 vs. 17 mm, p < 0.001). Associated anomalies were less frequent in females (n = 15, 13.2%) compared with males (n = 15, 34.1%). In females (n = 114), most cysts were of ovarian origin (n = 81, 71.1%). Surgery was performed in 30 (26.3%) female and 15 (34.1%) male neonates (p = 0.33). Anorectal malformations were present in 6 cases and often not recognized prenatally. Conclusions: The differences in the origin of intra-abdominal cysts between male and female fetuses, resulting in differences in prenatal presentation and postnatal outcome should be taken into account in prenatal counseling within a multidisciplinary team. Evaluation of the fetal perianal muscular complex is indicated.

The recent outbreak of the Zika virus (ZIKV) and the discovery that perinatal Zika exposure can lead to the Congenital Zika Syndrome has promoted a call for prevention measures. Due to the increased number of babies born with microcephaly, structural brain abnormalities, and neurological alterations in regions affected by ZIKV, investigations were carried out in order to better understand this process. The maternal immune system directly influences the fetal central nervous system, and complications during pregnancy have been associated with neurodevelopmental disorders. Autism spectrum disorder (ASD), a neurodevelopmental disorder commonly manifested in the first years of life, is a disease with multifactorial etiology and is manifested typically by social and communication impairments, as well as stereotyped behaviors. Brain abnormalities, including both anatomically and functionally, can be observed in this disorder, suggesting delays in neuronal maturation and altered brain connectivity. It is known that some viral congenital infections, such as rubella, and cytomegalovirus can interfere with brain development, being associated with brain calcification, microcephaly, and ASD. Here, we reviewed a range of studies evaluating the aspects concerning brain development, immunological status during pregnancy, and neuroimmunomodulation in congenital viral infections, and we discuss if the fetal brain infection caused by ZIKV could predispose to ASD. Finally, we suggest a mechanism encompassing neurological and immunological pathways that could play a role in the development of ASD in infants after ZIKV infection in pregnancy.

Published: January 2019

Dilated cardiomyopathy (DCM) is a severe cardiovascular disease which can lead to heart failure and sudden cardiac death (SCD). The typical feature of DCM is left ventricular enlargement or dilatation. In some conditions, DCM and arrhythmia can occur concurrently, apparently promoting the prevalence of SCD. According to previous studies, mutations in more than 100 genes have been detected in DCM and/or arrhythmia patients. Here, we report a Chinese family with typical DCM, ventricular tachycardia, syncope, and SCD. Using whole-exome sequencing, a novel, likely pathogenic mutation (c.959T>G/p.L320R) of actinin alpha 2 (ACTN2) was identified in all affected family members. This novel mutation was also predicted to be disease-causing by MutationTaster, SIFT, and Polyphen-2. Our study not only expands the spectrum of ACTN2 mutations and contributes to the genetic diagnosis and counseling of the family, but also provides a new case with overlap phenotype that may be caused by the ACTN2 variant.
Leukemia Inhibitory Factor Represses GnRH Gene Expression via cFOS during Inflammation in Male Mice
Authors: Lainez Nancy M. , Coss Djurdjica
Published: January 2019

Background: The mechanisms whereby neuroinflammation negatively affects neuronal function in the hypothalamus are not clear. Our previous study determined that obesity-mediated chronic inflammation elicits sex-specific impairment in reproductive function via reduction in spine density in gonadotropin-releasing hormone (GnRH) neurons. Neuroinflammation and subsequent decrease in GnRH neuron spine density was specific for male mice, while protection in females was independent of ovarian estrogens. Methods: To examine if neuroinflammation-induced cytokines can directly regulate GnRH gene expression, herein we examined signaling pathways and mechanisms in males in vivo and in GnRH-expressing cell line, GT1–7. Results: GnRH neurons express cytokine receptors, and chronic or acute neuroinflammation represses GnRH gene expression in vivo. Leukemia inhibitory factor (LIF) in particular represses GnRH expression in GT1–7 cells, while other cytokines do not. STAT3 and MAPK pathways are activated following LIF treatment, but only MAPK pathway, specifically p38α, is sufficient to repress the GnRH gene. LIF induces cFOS that represses the GnRH gene via the -1,793 site in the enhancer region. In vivo, following high-fat diet, cFOS is induced in GnRH neurons and neurons juxtaposed to the leaky blood brain barrier of the organum vasculosum of the lamina terminalis, but not in the neurons further away. Conclusion: Our results indicate that the increase in LIF due to neuroinflammation induces cFOS and represses the GnRH gene. Therefore, in addition to synaptic changes in GnRH neurons, neuroinflammatory cytokines directly regulate gene expression and reproductive function, and the specificity for neuronal targets may stem from the proximity to the fenestrated capillaries.

Published: January 2019

Background:

The left-ventricular myocardial performance index Tei is an echocardiographic parameter that incorporates the information of systolic and diastolic time intervals. While the prognostic value of selected systolic and diastolic parameters is well established after transcatheter aortic valve replacement, the role of Tei has not been evaluated in this setting.

Methods and Results:

Between August 2007 and December 2015, consecutive patients with symptomatic, severe aortic stenosis and transthoracic echocardiography pre- and post-transcatheter aortic valve replacement were considered eligible for this analysis. The primary end point was all-cause mortality at 1 year after transcatheter aortic valve replacement. Of 824 patients with echocardiographic images to calculate Tei, pre-Tei was normal (<0.45) in 639 and high (≥0.45) in 185, whereas post-Tei was normal in 602 and high in 120, respectively. After adjustment for confounding factors, high pre-Tei was associated with an increased risk of all-cause mortality at 30 days (adjusted hazard ratio [HR
adj
] 3.62; 95% CI, 1.89–6.91) and 1 year (HR
adj
2.56; 95% CI, 1.78–3.69). Similarly, post-Tei was associated with an increased risk of mortality between 30 days and 1-year follow-up (HR
adj
6.70; 95% CI, 4.22–10.63). At multivariable analysis Tei emerged as an independent predictor of early (pre-Tei index per 0.1–HR
adj
1.40; 95% CI, 1.23–1.60) and late mortality (post-Tei index per 0.1–HR
adj
1.40; 95% CI, 1.31–1.50), respectively.

Conclusions:

The left-ventricular myocardial performance index Tei is associated with impaired clinical outcomes during short- and longer-term follow-up after transcatheter aortic valve replacement.

The Amazon region contains a great diversity of species, and the Amazon River basin accounts for almost 20% of all the freshwater in the world. Despite the favorable environmental conditions in this region, little is known about the cyanobacterial diversity of this waterbody, especially at the mouth of the river. In this paper, we used the polyphasic approach to identify 14 cyanobacterial strains isolated in the Amazon River on the inlet site from a drinking water supply located close to the river mouth. The isolated strains were characterized based on morphology, behavior in culture, 16S rRNA gene sequencing, phylogenetic analysis and potential for toxin production. The isolated strains belong to seven different genera, namely, Alkalinema, Cephalothrix, Limnothrix, Leptolyngbya, Phormidium, Pseudanabaena and an unidentified Nostocales taxa that may represent a new genus. Strikingly, there were no new species, nor detection of gene clusters associated with cyanotoxin production. However, the phylogenetic placements of the Amazonian strains of Limnothrix and Pseudanabaena provide new insight into the taxonomy of these genera, reinforcing the need for taxonomic revision.

Published: January 2019

We have revised all the specimens of Araneidae from the Colombian Amazon Region in the Arachnological Collection of the Instituto de Ciencias Naturales at the Universidad Nacional de Colombia (ICN), in addition to the specimens collected between 2000 and 2004 by the authors in the lower Caquetá and Apaporis rivers (Amazonas and Vaupés, Colombia). A total of 77 new records for Araneidae in the Colombian Amazon are reported; 26 of these species are new records for the country and the region in addition to 15 more species known for Colombia but newly recorded in the region, the distribution of the remaining 36 species is expanded within the region. The genera Encyosaccus Simon 1865 (E. sexmaculatus Simon 1895), Hingstepeira Levi 1995 (H. folisecens Hingston 1932) and Micrepeira Schenkel 1953 (M. fowleri Levi 1995 and M. tubulofasciens Hingston 1932) are recorded for the first time in Colombia. From this revision, it is evident the great amount of new information available in museum collections. Due to the strategic geographic position of Colombia, species inventories in different localities of the Colombian Amazon Region are important to fill distributional gaps of many species in South America. This work contributes to the knowledge of geographic distribution patterns of orb-weaving species in Colombia and in the entire Amazon Region.

In Peru most tadpoles of the aquatic frogs genus Telmatobius belong to the lentic or lotic benthic guild. Members of this guild have a labial tooth row formula (LTRF) of 2/3, dorsolateral eyes, relative depressed bodies, dorsal fin do not extend beyond tail-body junction and they inhabit non flowing systems or microhabitats of non flowing portions of lotic systems (Altig & Johnson 1989, Aguilar et al. 2007, Aguilar & Lehr 2009). Only one species, T. atahualpai Wiens, is known to have a lotic rheophilous larva because it has a large oral disc, LTRF of more than 2/3, complete marginal papillae, numerous submarginal papillae and it inhabits streams (Altig & Johnson 1989, Aguilar & Lehr 2009). However, of the 25 Telmatobius species present in the Peruvian Andes (Frost 2010), tadpoles of only 11 species (44%) have been described, including the recently described tadpole of Telmatobius mayoloi Salas and Sinsch (Aguilar & Lehr 2009). Telmatobius brevirostris Vellard is endemic to central Peru, Huánuco region, with an altitudinal distribution ranging from 2000 to 3600 m.a.s.l. (Lehr 2005). Data on adult morphology, tadpole habitat, oral cavity and chondrocranium were given by Lehr (2005) and Aguilar & Valencia (2009), but tadpoles were left undescribed. Herein we describe the tadpole of T. brevirostris.

Authors: RUIZ GUSTAVO RODRIGO SANCHES
Published: January 2019

Two new genera of jumping spiders are proposed to include new heliophanines from Brazil. Kupiuka gen. nov. is based on the type species K. extratheca sp. nov. and Plesiopiuka gen. nov. is based on P. simplex sp. nov., both from the State of Amazonas. Besides its type species, Kupiuka includes K. murici sp. nov. from the State of Alagoas, K. overalli sp. nov. from the State of Pará, K. taruman sp. nov. and K. adisi sp. nov. from the State of Amazonas, K. heteropicta sp. nov. and K. vochysiae sp. nov. from the State of Mato Grosso and K. paulista sp. nov. from the State of São Paulo.
Genetypes: a concept to help integrate molecular phylogenetics and taxonomy
Authors: CHAKRABARTY PROSANTA
Published: January 2019

In order to better integrate molecular phylogenetics and taxonomy, genetic sequences from type materials should be explicitly identified in publications using a consistent nomenclature. Despite relatively frequent sampling of sequences from types (particularly topotypes—samples from the type locality), the practice of explicitly noting that these materials were sampled is uncommon. Because of the lack of an explicit nomenclature tied to taxonomy, the existence of genetic “type sequences” is obscured. Also hindering progress in taxonomy is the increasingly uncommon practice of reporting locality and voucher information (e.g., GPS coordinates, museum catalog numbers) on repositories such as GenBank. To remedy this problem and bring awareness to the situation, I propose the use of the term “genetype” as a label for any sequence data from types (including from holotypes, secondary types, topotypes, etc.).

The Nature of Cation–Anion Interactions in Magnetic Ionic Liquids as Revealed Using High-Pressure Fourier Transform Infrared (FT-IR) Spectroscopy
Authors: Burba Christopher M. , Chang Hai-Chou
Published: January 2019

Magnetic ionic liquids are a group of magneto-responsive compounds that typically possess high ionic conductivities and low vapor pressures. In spite of the general interest in these materials, a number of questions concerning the fundamental interactions among the ions remain unanswered. We used vibrational spectroscopy to gain insight into the nature of these interactions. Intramolecular vibrational modes of the ions are quite sensitive to their local potential energy environments, which are ultimately defined by cation–anion coordination schemes present among the ions. Ambient pressure Fourier transform infrared (FT-IR) spectroscopy indicates comparable interaction motifs for 1-ethyl-3-methylimidazolium tetrachloroferrate(III), [emim]FeCl4, and 1-ethyl-3-methylimidazolium tetrabromoferrate(III), [emim]FeBr4, magnetic ionic liquids. However, the vibrational modes of [emim]FeCl4 generally occur at slightly higher frequencies than those of [emim]FeBr4. These differences reflect different interaction strengths between the [emim]+ cations and [Formula: see text] or [Formula: see text] anions. This conclusion is supported by gas-phase ab initio calculations of single [emim]FeCl4 and [emim]FeBr4 ion pairs that show longer C–H···Br–Fe interaction lengths compared to C–H···Cl–Fe. Although the IR spectra of [emim]FeCl4 and [emim]FeBr4 are comparable at ambient pressure, a different series of spectroscopic changes transpire when pressure is applied to these compounds. This suggests [emim]+ cations experience different types of interaction with the anions under high-pressure conditions. The pressure-dependent FT-IR spectra highlights the critical role ligands attached to the tetrahalogenoferrate(III) anions play in modulating cation–anion interactions in magnetic ionic liquids.
Reconsidering Cutoff Points in the General Method of Empirical Q-Matrix Validation
Authors: Nájera Pablo , Sorrel Miguel A. , Abad Francisco José
Published: January 2019

Cognitive diagnosis models (CDMs) are latent class multidimensional statistical models that help classify people accurately by using a set of discrete latent variables, commonly referred to as attributes. These models require a Q-matrix that indicates the attributes involved in each item. A potential problem is that the Q-matrix construction process, typically performed by domain experts, is subjective in nature. This might lead to the existence of Q-matrix misspecifications that can lead to inaccurate classifications. For this reason, several empirical Q-matrix validation methods have been developed in the recent years. de la Torre and Chiu proposed one of the most popular methods, based on a discrimination index. However, some questions related to the usefulness of the method with empirical data remained open due the restricted number of conditions examined, and the use of a unique cutoff point ( EPS) regardless of the data conditions. This article includes two simulation studies to test this validation method under a wider range of conditions, with the purpose of providing it with a higher generalization, and to empirically determine the most suitable EPS considering the data conditions. Results show a good overall performance of the method, the relevance of the different studied factors, and that using a single indiscriminate EPS is not acceptable. Specific guidelines for selecting an appropriate EPS are provided in the discussion.

Authors: Hivner Elizabeth A , Hoke Alicia M , Francis Erica B , Lehman Erik B , Hwang Grace W , Kraschnewski Jennifer L
Published: January 2019

Objective:

To evaluate the impact of three types of social cognitive theory (SCT)-based elementary school classroom physical activity (PA) training on teachers’ implementation rates, attitudes, knowledge and behaviour.

Design:

Key stakeholder focus groups informed development of phase II which took the form of a randomised controlled trial of three different intensities of teacher training to conduct classroom-based PA sessions.

Setting:

The study was conducted over one school year (2016–2017), across four elementary schools in the USA.

Methods:

Researchers delivered professional development to teachers, focusing on effective methods for PA use in the classroom through three formats: webinar, in-person training and in-person with personalised assistance. Training content was built on SCT constructs. This study examined the impact of the PA training on SCT construct outcomes among elementary school classroom teachers ( n = 41). Study outcome measures included reciprocal determinism, behavioural capability, outcome expectations and self-efficacy. Over the 12-week period following the training, teachers completed surveys to measure SCT construct outcomes.

Results:

Results of the intervention demonstrated an increase in teacher self-efficacy and knowledge ( p < .01 and p < .01). There was a significant increase of teachers who started using PA in the classroom who indicated no use at baseline (from 21% to 6% not using).

Conclusion:

The use of SCT to provide a teacher training is an effective method to increase classroom PA, while improving teacher self-efficacy and knowledge concerning PA implementation.
Integration of an Academic Medical Center and a Large Health System: Implications for Pharmacy
Authors: Erstad Brian L. , Aramaki Tina , Weibel Kurt
Published: January 2019

Objective: To provide lessons learned for colleges of pharmacy and large health systems that are contemplating or in the process of undergoing integration. Method: This report describes the merger of an academic medical center and large health system with a focus on the implications of the merger for pharmacy from the perspectives of both a college of pharmacy and a health system’s pharmacy services. Results: Overarching pharmacy issues to consider include having an administrator from the college of pharmacy directly involved in the merger negotiation discussions, having at least one high-level administrator from the college of pharmacy and one high-level pharmacy administrator from the health system involved in ongoing discussions about implications of the merger and changes that are likely to affect teaching, research, and clinical service activities, having focused discussions between college and health system pharmacy administrators on the implications of the merger on experiential and research-related activities, and anticipating concerns by clinical faculty members affected by the merger. Conclusion: The integration of a college of pharmacy and a large health system during the acquisition of an academic medical center can be challenging for both organizations, but appropriate pre- and post-merger discussions between college and health system pharmacy administrators that include a strategic planning component can assuage concerns and problems that are likely to arise, increasing the likelihood of a mutually beneficial collaboration.
Practices and knowing in transnational knowledge-intensive service provision
Authors: Hydle Katja Maria , Hopwood Nick
Published: January 2019

How do professionals at different locations within a firm collaborate to provide services across borders? This article addresses how knowledge-intensive service provisions are coordinated across borders, time zones and expertise. Empirical material from two engineering firms providing services to a global customer base are analysed, comprising over 100 interviews and over 20 days of observation. Concepts from practice theory are used, locating questions of knowledge in the realm of practical action. Findings describe how transnational services are enacted through prefigured and emergent practices. The problem of coordinating transnational practices is considered as a matter of balanced acting between these contrasting forms of work. This is explored in terms of the forms of knowledge that are in play – nuancing practical understanding into specific notions of know-how, know-what, know-who, know-why and know-where/when. Connecting this array of knowledge forms with balanced acting between prefigured and emergent practices extends theorizations of transnational knowledge-intensive firms, and casts new light on how the widespread problem of coordination can be addressed.
An exploratory multi-site mixed-method study with migrants at Niger transit centers: The push factors underpinning outward and return migration
Authors: Veronese Guido , Pepe Alessandro , Vigliaroni Marzia
Published: January 2019

In our work, we explored factors of outward migration and the factors that drive migrants to return to their countries of origin. All participants were recruited at transit centers in Niger. Interviews were analyzed using a Quantitative Text Analysis methodology. Results showed that the push factors are organized along two dimensions, economic (job search, breadwinner, poverty) and subjective psychological/social components (disruption of social networks, educational, personal ambitions). The decision to return is represented by a dimension of human insecurity (repression, prison, death) and internal/external reasons ranging from spontaneous to forced return. Implications for social work are discussed.
Reuse of carbon black from end-of-life tires in new pneumatic formulations and life-cycle assessment of the thermolysis process
Authors: La Rosa AD , Pergolizzi E , Maragna D , Recca G , Cicala G
Published: January 2019

Carbon black derived from end-of-life tires (ELTs) through thermolysis process was studied. The main attraction of this material is the low market price (€450 ton−1) compared with virgin carbon black (about €700 ton−1). Investigation was focused on the vulcanization reaction of rubber with the addition of both types of carbon black, that is, carbon black recycled (CBr) from the thermolysis of ELTs and carbon black virgin (CBv) from traditional oil process. The aim of the research was to verify that CBr has similar reactivity than CBv when blended with rubber and vulcanized. Furthermore, environmental benefits of recovering CBr and the other coproducts were evaluated by means of the life-cycle assessment methodology.
