Published: August 2019

Utilization of the French system of vertical wetlands for treating raw sewage keeps increasing, but there is still limited consolidated information on their long term use in tropical countries. Under these conditions, there are indications that surface area requirements can decrease, whilst still keeping a satisfactory performance. However, variations in the operational mode and the role of the surface organic deposit layer under warm climatic conditions have not been fully investigated. The goal of this work was to evaluate the performance of a system comprised of only the first stage of the French system, with a further reduction of 1/3 of the area (utilization of only two units in parallel, instead of three) in terms of organic matter removal and nitrogen conversion, with one unit with a deposit layer accumulated over 9 years of operation, and the other unit without sludge layer, under Brazilian tropical conditions. The system was originally designed according to Cemagref/Irstea recommendations for the first-stage of the French system for the treatment of raw sewage generated by an equivalent population of 100 inhabitants. However, it was later on changed, and operated with only two units, using only 0.6 m2·pe−1. Feeding and resting periods were of 7 days each. In order to evaluate the influence of the sludge layer, the top sludge from one of the units was removed, and the performance of both units was compared by the Mann-Whitney test. The database comprises the wetland performance values in terms of dissolved oxygen (DO), redox potential (Eh), chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS), total Kjeldahl nitrogen (TKN), NH4+-N and NO3+-N, covering a monitoring period of 15 months. The effluent DO concentrations were significantly lower in the unit with top sludge, but still sufficiently high in both units. Although there were some variations between both units, effluent concentrations of the major pollutants were not significantly different in the units with and without sludge, and removal efficiencies based on mean values were considered good, given the reduced area of the system: BOD (80% and 79%), TSS (85% and 82%), TKN (60% and 63%) for the units with and without sludge, respectively. Under Brazilian climatic conditions, with the reduced area and employing longer feeding cycles (7 days), the sludge accumulation rate (less than 1 cm·year−1) was lower compared to the French mean values.

Carbazole derivatives have extensive π–conjugation due to which they are excellent
organic electronics and show semiconducting properties. Carbazole-based various
materials are important candidates due to their excellent redox and luminescent properties
and good thermal and environmental stability, therefore, carbzole nucleus was chosen for
exploring these properties. The title compound was recrystallized from a methanol solution
in orthorhombic space group P 212121 with unit cell dimensions a = 9.663(2), b =
10.764(3), c =18.139(4), V= 1886.7(7) Å3, Z=4. Density functional theory (DFT) calculations
have been carried out for the title compound using the 6-31G(d) basis set. The calculated
results showed that the theoretically predicted geometry can well reproduce the experimentally
calculated structural parameters.

Authors: Sathiyanarayanan Singaram , Venkatesan Chidambaram Subramanian , Kabilan Senthamaraikannan
Published: August 2019

Background:

Regadenoson is an A2A adenosine receptor agonist that is a coronary vasodilator
and commonly used as a pharmacologic cardiac stressing agents.

Methods:

HPLC method was used for the analysis of related substances. The degraded impurities during
the process were isolated and characterized by IR, Mass and NMR spectral analysis.

Results:

Forced degradation study of regadenoson under conditions of hydrolysis (neutral, acidic and
alkaline) and oxidations suggested in the ICH Q1A(R2) was accomplished. The drug showed significant
degradation under all the above conditions. On the whole, five novel degradation products were found
under diverse conditions along with process related impurities which were not reported earlier.

Conclusion:

All the degradation products were well characterized by using advanced spectroscopic techniques
like IR, 1H NMR, 13C NMR and Mass spectra. The identification of these impurities will be productive
for the quality control during the production and stability behavior of the regadenoson drug substance.
A Fast Method for Defogging of Outdoor Visual Images
Authors: Pal Tannistha
Published: August 2019

Background:

Capturing image in severe atmospheric catastrophe especially in fog critically
degrades the quality of an image and thereby reduces its visibility of which in turn affects several
computer vision applications like visual surveillance detection, intelligent vehicles, remote
sensing, etc. Thus acquiring clear vision is the prime requirement of any image. In the last few
years, many approaches have been directed towards solving this problem.

Methods:

In this article, a comparative analysis has been made on different existing image defogging
algorithms and then a technique has been proposed for image defogging based on dark channel
prior strategy.

Results:

Experimental results show that the proposed method shows efficient results by significantly
improving the visual effects of images in foggy weather. Also the much higher computational time
of the existing techniques has been reduced in this paper by using the proposed method.

Discussion:

Qualitative assessment evaluation was performed on both benchmark and real time data
sets for determining the efficacy of the technique used. Finally, the whole work is concluded with
the relative advantages and shortcomings of the proposed technique.

Authors: Sharma Shashank , Srivastava Sumit
Published: August 2019

Background:

Workflow extraction is the connecting link between process modelling and
data mining. Extraction of information and make insight from it using event log is the primary objective
of workflow mining. The learning got along these logs can build comprehension about the
workflow of procedures and association of different processes. That can help with upgrading them
if necessary.

Objective:

The aim of this paper is to display a process performance based framework where we
compare reference model with extracted model (from a large information system) on the basis of
key performance indices.

Methods:

Proposed approach perform extraction of workflow model using workflow mining. This
process is effective and efficient as compare with building work flow model from scratch. This
shows a logic about how to program event log data gathered from different sensors (Internet of
Events). How we process and investigates to handle and propel the item work process by using the
course of action.

Results:

Proposed approach displays a process based framework for the legacy system that ensures
the effective and efficient working. So that accordingly extracted model behave like referenced model
and results are validated by Key Performance Indices (KPI) for evaluating process performance.

Conclusion:

In this experimental data centric approach, our progressing work is to research a metric
to quantify the nature of reference models and extracted model. On the basis of metric values,
we take the decision on legacy information system process management.
Minimized False Alarm Predictive Threshold for Cloud Service Providers
Authors: Arora Amandeep S. , Raja Linesh , Bahl Barkha
Published: August 2019

Background:

Cloud Security is a strong hindrance which discourages organisations to move toward
cloud despite huge benefits. Distributed denial of service attacks operated via distributed systems
compromise availability of cloud services which cause limited resources for authentic users
and high expense for cloud service users and business owners.

Objective:

Techniques to identify distributed denial of service attacks with minimized false positives
are highly required to ensure availability of cloud services to genuine users. Scarcity of solution
which can detect denial of service attacks with minimum false positives and reduced detection
delay has motivated us to compare classification algorithms for detection of distributed denial of
service attacks with minimum false positive rate.

Methods:

Classification of incoming requests and outgoing responses using machine learning algorithms
is a quite effective way of detection and prevention. We designed a performance tuned support
vector machine algorithm with features of F-hold cross validation strategy.

Results:

F-hold crosses validation strategy, which can detect denial of service packets with 99.89%
accuracy.

Conclusion:

This system ensures economic sustainability for business owners and limited resources
mitigation for authenticated and valid cloud users.

Periodic discharge in a flow of liquid is one of the effective ways of modifying the surface of metal products in order to increase their durability, hardness and corrosion resistance. Researching of the properties of the discharge in order to determine the limits of capability of this method and the optimization of technological regimes revealed a number of physical phenomena that were not previously known. Consideration of these factors is necessary when determining safety measures in the implementation of industrial technologies. A new element is the consideration of detected anomalous manifestations of new formations such as balls, tracks and threads in the environment.

The paper presents the results of the study of decaying neon plasma by the method of kinetic spectroscopy. Experimental conditions: neon pressure 0.2–152 Torr, electron density in the initial stage of decay [e] ≤ 5 × 1010 cm-3. The plasma was created by a pulsed barrier discharge with electrodes on the outer surface of a cylindrical glass tube. Discharge frequency 40–160 Hz. On the basis of a comparative analysis of the dependences of the intensities of spectral lines on the time and temperature of electrons in the afterglow, it was shown that in terms of the mechanisms of population, the levels of 2p54p are clearly divided into two groups. Lower levels: from 3p10 to 3p3 (Paschen notation) are associated with the dissociative recombination of molecular ions with electrons and, up to pressures of 0.6 Torr, the lines emitted by them behave identically to the lines of 2p53s ← 2p53p and 2p53p ← 2p53d transitions. The behavior of the upper levels (3p5, 3p2, 3p4, and 3p1) was more complex, and at low pressures, the populations of all 2p54p levels turned out to be related to the impact-radiation recombination of Ne + ions. Significant differences in the dependences of the relative populations of 3d and 4p levels on the neon pressure are discussed.

Patient Recommendations to Improve the Implementation of and Engagement With Portals in Acute Care: Hospital-Based Qualitative Study
Authors: Greysen S Ryan , Magan Yimdriuska , Rosenthal Jamie , Jacolbia Ronald , Auerbach Andrew D , Harrison James D
Published: August 2019

Background

The inclusion of patient portals into electronic health records in the inpatient setting lags behind progress in the outpatient setting.

Objective

The aim of this study was to understand patient perceptions of using a portal during an episode of acute care and explore patient-perceived barriers and facilitators to portal use during hospitalization.

Methods

We utilized a mixed methods approach to explore patient experiences in using the portal during hospitalization. All patients received a tablet with a brief tutorial, pre- and postuse surveys, and completed in-person semistructured interviews. Qualitative data were coded using thematic analysis to iteratively develop 18 codes that were integrated into 3 themes framed as patient recommendations to hospitals to improve engagement with the portal during acute care. Themes from these qualitative data guided our approach to the analysis of quantitative data.

Results

We enrolled 97 participants: 53 (53/97, 55%) women, 44 (44/97, 45%) nonwhite with an average age of 48 years (19-81 years), and the average length of hospitalization was 6.4 days. A total of 47 participants (47/97, 48%) had an active portal account, 59 participants (59/97, 61%) owned a smartphone, and 79 participants (79/97, 81%) accessed the internet daily. In total, 3 overarching themes emerged from the qualitative analysis of interviews with these patients during their hospital stay: (1) hospitals should provide both access to a device and bring-your-own-device platform to access the portal; (2) hospitals should provide an orientation both on how to use the device and how to use the portal; and (3) hospitals should ensure portal content is up to date and easy to understand.

Conclusions

Patients independently and consistently identified basic needs for device and portal access, education, and usability. Hospitals should prioritize these areas to enable successful implementation of inpatient portals to promote greater patient engagement during acute care.

The Validity of Daily Self-Assessed Perceived Stress Measured Using Smartphones in Healthy Individuals: Cohort Study
Authors: Þórarinsdóttir Helga , Faurholt-Jepsen Maria , Ullum Henrik , Frost Mads , Bardram Jakob E , Kessing Lars Vedel
Published: August 2019

Background

Smartphones may offer a new and easy tool to assess stress, but the validity has never been investigated.

Objective

This study aimed to investigate (1) the validity of smartphone-based self-assessed stress compared with Cohen Perceived Stress Scale (PSS) and (2) whether smartphone-based self-assessed stress correlates with neuroticism (Eysenck Personality Questionnaire-Neuroticism, EPQ-N), psychosocial functioning (Functioning Assessment Short Test, FAST), and prior stressful life events (Kendler Questionnaire for Stressful Life Events, SLE).

Methods

A cohort of 40 healthy blood donors with no history of personal or first-generation family history of psychiatric illness and who used an Android smartphone were instructed to self-assess their stress level daily (on a scale from 0 to 2; beta values reflect this scale) for 4 months. At baseline, participants were assessed with the FAST rater-blinded and filled out the EPQ, the PSS, and the SLE. The PSS assessment was repeated after 4 months.

Results

In linear mixed-effect regression and linear regression models, there were statistically significant positive correlations between self-assessed stress and the PSS (beta=.0167; 95% CI 0.0070-0.0026; P=.001), the EPQ-N (beta=.0174; 95% CI 0.0023-0.0325; P=.02), and the FAST (beta=.0329; 95% CI 0.0036-0.0622; P=.03). No correlation was found between smartphone-based self-assessed stress and the SLE.

Conclusions

Daily smartphone-based self-assessed stress seems to be a valid measure of perceived stress. Our study contains a modest sample of 40 healthy participants and adds knowledge to a new but growing field of research. Smartphone-based self-assessed stress is a promising tool for measuring stress in real time in future studies of stress and stress-related behavior.
Effectiveness of One-Way Text Messaging on Attendance to Follow-Up Cervical Cancer Screening Among Human Papillomavirus–Positive Tanzanian Women (Connected2Care): Parallel-Group Randomized Controlled Trial (Preprint)
Authors: Linde Ditte S , Andersen Marianne S , Mwaiselage Julius , Manongi Rachel , Kjaer Susanne K , Rasch Vibeke
Published: August 2019

BACKGROUND

Rapid human papillomavirus (HPV) DNA testing is an emerging cervical cancer screening strategy in resource-limited countries, yet it requires follow-up of women who test HPV positive.

OBJECTIVE

This study aimed to determine if one-way text messages improved attendance to a 14-month follow-up cervical cancer screening among HPV-positive women.

METHODS

This multicenter, parallel-group randomized controlled trial was conducted at 3 hospitals in Tanzania. Eligible participants were aged between 25 and 60 years, had tested positive to a rapid HPV test during a patient-initiated screening, had been informed of their HPV result, and had a private mobile phone with a valid number. Participants were randomly assigned in a 1:1 ratio to the intervention or control group through an incorporated algorithm in the text message system. The intervention group received one-way text messages, and the control group received no text messages. The primary outcome was attendance at a 14-month health provider-initiated follow-up screening. Participants were not blinded, but outcome assessors were. The analysis was based on intention to treat.

RESULTS

Between August 2015 and July 2017, 4080 women were screened for cervical cancer, of which 705 were included in this trial—358 women were allocated to the intervention group, and 347 women were allocated to the control group. Moreover, 16 women were excluded before the analysis because they developed cervical cancer or died (8 from each group). In the intervention group, 24.0% (84/350) women attended their follow-up screening, and in the control group, 23.8% (80/335) women attended their follow-up screening (risk ratio 1.02, 95% CI 0.79-1.33).

CONCLUSIONS

Attendance to a health provider-initiated follow-up cervical cancer screening among HPV-positive women was strikingly low, and one-way text messages did not improve the attendance rate. Implementation of rapid HPV testing as a primary screening method at the clinic level entails the challenge of ensuring a proper follow-up of women.

Effect of Health Care Provider Delays on Short-Term Outcomes in Patients With Colorectal Cancer: Multicenter Population-Based Observational Study (Preprint)
Authors: Abdulaal Ahmed , Arhi Chanpreet , Ziprin Paul
Published: August 2019

BACKGROUND

The United Kingdom has lower survival figures for all types of cancers compared to many European countries despite similar national expenditures on health. This discrepancy may be linked to long diagnostic and treatment delays.

OBJECTIVE

The aim of this study was to determine whether delays experienced by patients with colorectal cancer (CRC) affect their survival.

METHODS

This observational study utilized the Somerset Cancer Register to identify patients with CRC who were diagnosed on the basis of positive histology findings. The effects of diagnostic and treatment delays and their subdivisions on outcomes were investigated using Cox proportional hazards regression. Kaplan-Meier plots were used to illustrate group differences.

RESULTS

A total of 648 patients (375 males, 57.9% males) were included in this study. We found that neither diagnostic delay nor treatment delay had an effect on the overall survival in patients with CRC (χ23=1.5, P=.68; χ23=0.6, P=.90, respectively). Similarly, treatment delays did not affect the outcomes in patients with CRC (χ23=5.5, P=.14). The initial Cox regression analysis showed that patients with CRC who had short diagnostic delays were less likely to die than those experiencing long delays (hazard ratio 0.165, 95% CI 0.044-0.616; P=.007). However, this result was nonsignificant following sensitivity analysis.

CONCLUSIONS

Diagnostic and treatment delays had no effect on the survival of this cohort of patients with CRC. The utility of the 2-week wait referral system is therefore questioned. Timely screening with subsequent early referral and access to diagnostics may have a more beneficial effect.
The Relationship of Modern Medicine to the Book of Laws (The Pentateuch)
Authors: Olatomi, Ph.D. Soboyejo, Josephine
Published: August 2019

Theologians for centuries thought that many laws in the Pentateuch served a ceremonial function or aimed to distinguish Israel from the neighboring pagan cultures. In today’s world, there are many infectious and epidemic transmission of a variant of diseases that are killing human beings. This paper examines the escalation of the germ theory in the modern and postmodern world to prove that obedience to God’s rules confers essential health benefits. The paper used phenomenology, ethical, and evidential tools of philosophy, and theological approach in understanding how modern medicine relates to scriptural laws. The paper ascertains that the scriptural commandments as used by the priests confer medical benefits to the people if the modern culture is inclined to obey them. Some of the diseases in conceptualization are cancer, blood clotting, germs; parasites induced diseases, sexually transmitted diseases, and addiction, among others. The paper agrees that total obedience to Mosaic laws and complete trust in Biblical injunctions provide spiritual and physical fitness.
Literacy Teaching: How Much Grammar Is Required in Writing as an Expressive Skill?
Authors: Oladunjoye, PhD Oluwayomi S.
Published: August 2019

This paper is a one hypothesis research that investigates the perception of teachers on the effect of grammar on the expressive or productive skill of writing to provide a good platform for literacy teaching. One hundred undergraduates and post-graduates participants—50 each—were given a fifteen-item questionnaire to show their opinion on the relevance of grammar to the teaching of continuous writing. The hypothesis tested at 0.05 level of significance was rejected. Obtaining a mean score of 2.93 above the undergraduate students’ 1.92 in the t-test of the data collected, the findings show that the post-graduate students believe grammar is an essential part of good writing. The researcher consequently suggests ways of slicing up grammar teaching for better performance in writing.

Hybrid Logic as extension of Modal and Temporal Logic
Authors: Álvarez Domínguez Daniel
Published: August 2019

La lógica temporal fue creada por Arthur Prior para representar información temporal en un sistema lógico mediante operadores modales-temporales como P, F, H o G. Intuitivamente tales operadores pueden entenderse respectivamente como “fue alguna vez en el pasado...”, “será alguna vez en el futuro...”, “ha sido siempre en el pasado...” y “será siempre en el futuro...”. La evaluación de las fórmulas construidas a partir de ellos se lleva a cabo en semánticas kripkeanas y, de este modo, la lógica modal y la temporal están relacionadas. Sin embargo, aunque sus mecanismos permiten formalizar la información modal-temporal con cierta precisión, ambas lógicas adolecen de un problema de expresividad que la lógica híbrida es capaz de solventar. En efecto, uno de los problemas de la lógica modal reside en su incapacidad para nombrar puntos concretos dentro de un modelo. La lógica temporal, al basarse en ella, tampoco puede hacerlo. Pero la lógica de primer orden sí es capaz gracias a las constantes y a la relación de identidad. La lógica híbrida, que resulta de combinar la lógica modal con la lógica de primer orden, sería una solución a este problema. El principal objetivo de este artículo consiste en explicar el origen de la lógica híbrida a partir de la modal-temporal para mostrar qué añade a ambos sistemas en la representación de información, porqué es más expresiva que ellos y qué relación guarda con el lenguaje de correspondencia de la lógica de primer orden.

International internal audit standards (IIA) and the geographical location of international groups: An application to the information technology sector
Authors: Feghali Khalil , Hallak Joe
Published: August 2019

The international standards for internal audit (IIA) created by the Internal Audit Institute in the United States are presently one of the most important bases for the practice of the internal audit profession. In this research, we assess the use of these principles in international groups through empirical studies, adopting an objective evaluation of the application of the standards.
This multivariate statistical study was conducted in 2017 on more than 22 countries covering Africa, Middle East and Europe. Data was collected through a validated questionnaire covering two topics: general company information, and international internal audit standards applicability and relevance. Statistical analysis was performed using SPSS-22 software (IBM, New York, USA).
Results showed that audit quality components, information technology and accounting and finance have a favorable correlation with the international standards. In conclusion, these findings suggest such standards are expected to enhance the internal audit practice. As such, international companies should consider applying these standards in their core practice promote the application of the standards through complying their audit practice strategies to the regulations.

mundo, tal y como se configuran tras la crisis del petróleo. Este escenario
ha planteado un nuevo contexto para las intervenciones políticas sobre el
mundo del trabajo: una estructura social reconfigurada, unas capacidades
estatales diluidas, unos modelos de producción renovados, unos modos de
regulación social adaptados a los tiempos que corren.

Una constante, sin embargo, atraviesa el conjunto de estas transformaciones:
el trabajo (ámbito de intervención que le da cuerpo a este dossier) continúa siendo la principal vía de reproducción material y simbólica para la grandísima mayoría de la población humana y, en este sentido, constituye (por presencia o ausencia) el basamento fundamental para la sociabilidad y las identificaciones, así como también para las articulaciones políticas, la formación de esquemas culturales y visiones de mundo.

En este nuevo contexto social, la noción de empleabilidad y su repertorio
de diagnósticos y soluciones han resultado el enfoque hegemónico en
cuanto al diseño e implementación de las políticas de empleo. Así, el paradigma
de la activación y –los supuestos socioculturales que moviliza–
ha logrado imponer una definición de la problemática que opera como
lente y brújula para orientar los cursos de acción que pretenden resolver
lo que, probablemente, sea la forma más difundida en la que cristaliza la
cuestión social contemporánea: la problemática del empleo.
El Semestre Europeo en la política de empleo española ¿Hacia un enfoque con mayor contenido social?
Authors: Pablo Sanz de Miguel , Juan José Mediavilla Merino
Published: August 2019

El Semestre Europeo (SE) se ha configurado desde su creación en 2010
como una poderosa herramienta para reforzar la gobernanza y coordinación
de la política de empleo a nivel europeo. Entre los diversos debates que su puesta en marcha ha generado, este artículo aborda, a través de un análisis del caso español durante el periodo 2011-2017, la discusión respecto al supuesto incremento de su contenido social. La denominada tesis sobre la “socialización” del SE, se analiza desde la perspectiva de los inputs, es decir, se centra en las orientaciones políticas resultantes del proceso y su influencia en las políticas de empleo españolas y de su gobernanza, a partir del estudio de los procesos de diálogo y concertación social mediante los cuales se implementa el SE. Empíricamente, se recurre al análisis de los documentos elaborados por las instituciones europeas (Directrices de Empleo, Recomendaciones Específicas) y por el Gobierno de España (Programas Nacionales de Reforma y documentos legislativos) y cuestionarios abiertos respondidos por el Gobierno y los agentes sociales.
El sector empresarial y su influencia en las políticas de empleabilidad juvenil en Chile
Authors: Guillermo Rivera-Aguilera , Adela Bork , Cristian Nova
Published: August 2019

El presente artículo describe cómo el sector empresarial influye en las
políticas de empleo juvenil en Chile. Para esto se realiza un análisis de medios (Fairclough, 1995; Alonso, McCabe, Chornet-Roses, 2010) que toma como referencia prensa escrita entre 2014-2018. Los resultados dan cuenta que en los últimos años los discursos del sector empresarial promueven un discurso basado en el capital humano, la educación dual, la flexibilización laboral, así como un nuevo rol de las empresas en la problemática de desempleo juvenil. Desde una perspectiva del análisis crítico del discurso (Fairclough, 2010), que incorpora herramientas analíticas de políticas públicas (Rivera-Aguilera, 2017), se analiza cómo estos discursos empresariales generan prescripciones normativas, basadas en un binomio empresa-educación, cuyos efectos psicologizantes permiten estrategias de regulación social del empleo juvenil. En estos nuevos ordenes laborales, se discute respecto a las formas que tienen los discursos que emergen del corpus textual, en producción de sujetos laborales, los cuales promueven la habilitación de un ‘joven analfabeto’ en una serie de competencias que definen los mercados del trabajo. Si bien este artículo toma como referencia el caso chileno, este estudio puede contribuir a un entendimiento de la influencia del sector empresarial en las políticas de empleo juvenil en distintas realidades de Iberoamérica. Esto, en un contexto político marcado por una sincronía entre un modelo económico influido por la neoliberaización de las políticas del trabajo y un modo específico de promover subjetividades laborales en la juventud más vulnerable.

Trichomonas vaginalis infection is one of the sexually transmitted diseases. It is a health problem all over the world, including Iraq. It has also been associated with adverse outcomes of pregnancy and increased risk of HIV. Trichomoniasis typically elicits aggressive local cellular immune responses with inflammation of the vaginal epithelium and exocervix in women and urethra in men. The present study was aimed to assess serum level of interferon gamma (IFN-γ), Interleukin 10 (IL-10), C-reactive protein, antiphospholipid, anticardiolipin antibodies with eosinophil count as well. Four hundred and forty women with ages ranging between 16 and 60 years old (average of 34.2 years) who attended Maternity Teaching Hospital and a number of public health centers in Erbil Governorate were screened for trichomoniasis by direct wet mount preparation and culture technique. Serum IFN-γ, IL-10, antiphospholipid, and anticardiolipin were assessed by enzyme-linked immunosorbent assay. C-reactive protein (CRP) and eosinophil count were assessed by I CROMA and Coulter, respectively. The results revealed that IL-10 level (96.46 ± 1.97 pg/ml vs. 91.86 ± 1.48 pg/ml), eosinophil count (0.1 ± 0.07 × 10³/μL vs. 0.1 ± 0.01 × 10³/μL), and CRP concentration (2.55 ± 0.74 mg/l vs. 2.27 ± 0.37 mg/l) were non-significantly (P > 0.05) changed in infected women in comparison with negative control group. However, serum IFN-γ level (484.83 ± 38.35 pg/ml vs. 372.15 ± 9.49 pg/ml) was significantly (P < 0.05) elevated in infected women in comparison to the control group. The results also revealed significant increase (P < 0.05) of antiphospholipid immunoglobulin G (IgG) antibodies (4.75 ± 0.3 U/ml vs. 3.79 ± 0.11 U/ml) in the sera of infected women, but antiphospholipid immunoglobulin M (IgM), anticardiolipin IgG, and anticardiolipin IgM antibodies were non-significantly altered in response to T. vaginalis infection.

Helicobacter pylori is resident in human stomach and causes chronic disease (peptic ulcer and gastritis). The mouth and colon were both known to host a large number of microbes. This study was carried out to investigate the seroprevalence of H. pylori infection among Cihan University students. A total of 197 blood samples were collected from the students (53 females and 144 males) from 13 departments of Cihan University, Erbil, and tested for anti-H. pylori antibodies, using rapid immunochromatography assay. Among 197 students tested, 44 (22.3%) showed positive reaction for H. pylori, 32 males and 12 females. It was non-significantly higher among students with ages ranged between 29 and 32 years old. Twenty-one of infected students were using tap water for drinking. Twenty-six (59.1%) of positive students experienced no symptoms and 18 (40.9%) were symptomatic (13.63% epigastric pain and 27.2% abdominal pain).

The study included 258 Syrian refugees of different ages and sex and another 60 volunteers as control group (C.G). These refugees were in Kawergosk camp in Erbil Governorate. Blood was collected from each individual for the estimation of white blood cell (WBC), eosinophil, iron, hemoglobin (Hb), and immunoglobulin E (IgE) levels. Mean serum levels of IgE among male and female refugees showed highly significant increasing when compared to C.G. Most of the refugees had normal iron levels, where iron concentrations were more than 65 mg/dl among 67 males and more than 50 mg/dl among 104 females and 48 children, while some had iron deficiency in which the majority were female (9 males, 24 females, and 6 children had iron deficiency). In addition, Hb concentrations were normal among 65 males (more than 13.0 g/dl), 89 females (more than 11.0 g/dl), and 48 children (more than 12.0 g/dl). However, anemia was found among 8 men, 42 women, and 6 children. It was revealed that there was a highly significant rising in eosinophils in male and female refugees in comparison to C.G. WBC count is non-significantly slightly increased in both male’s and female’s refugees when compared to C.G.
