Abstract
Background
Blastocystis is one of the most common intestinal protozoa in human faecal samples with uncertain impact on public health. Studies on the prevalence of Blastocystis in HIV-positive patients are limited and dated.
Methods
A cross-sectional study was carried out involving 156 HIV- positive patients to evaluate the prevalence of Blastocystis subtypes, to identify the risk factors for its transmission, to examine the relationship between the presence of the protist and gastrointestinal disorders and to assess the level of calprotectin in Blastocystis-carriers.
Results
Blastocystis was identified in 39 patients (25%). No correlation was found between the presence of the protist and virological or epidemiological risk factors. Blastocystis was more frequently detected in homosexual subjects (p=0.037) infected by other enteric protozoa (p= 0.0001) and with flatulence (p=0.024). No significant differences in calprotectin level was found between Blastocystis-carriers and free ones.
Conclusions
Blastocystis is quite common in HIV-positive patients on ART and homosexual behaviour could represent a risk factor for its transmission. The pathogenetic role of Blastocystis remains unclear, as the only symptom associated with its presence was flatulence. This result is intriguing since flatulence is related to the composition and stability of gut microbiota.

Abstract
Background

Intestinal infection is still an important public health problem in low-income countries. Food handlers may be infected by a wide range of enteropathogens and have been implicated in the transmission of many infections to the public in the community and the people living in working environments. Therefore, this systematic review and meta-analysis estimate the pooled prevalence and factors associated with intestinal parasitic infections among food handlers working at higher public University student’s cafeterias and public food establishments in Ethiopia.

Methods

International databases, including PubMed/ Medline, Science Direct, Google Scholar, andHinariwere systematically searched. All identified observational studies reporting the prevalence and factors associated with intestinal parasitic infections at higher public University student’s cafeterias and public food establishments were included. Two authors independently extracted all necessary data using a standardized data extraction format. STATA version 14 statistical software was used to do a meta-analysis. The Cochrane Q test statistics and I2 test were used to assess the heterogeneity of the studies. A random-effect model was computed to estimate the pooled prevalence and factors associated with intestinal parasitic infections.

Results

After reviewing of 138 studies, 18 studies fulfilled the inclusion criteria and were included in the meta-analysis. The findings from the 18 studies revealed that the pooled prevalence of intestinal parasitic infection among food handlers working in higher public university student’s cafeterias and public food establishments was 28.5% (95%CI: 27.4, 29.7). The dominant intestinal parasites were E.histolytica 6.38 (95%Cl: 5.73, 7.04), followed by A.lumbricodes4.12 (95%Cl: 3.56, 4.67), and G. lamblia 3.12(95%Cl: 2.65, 3.60). Fingernail trimming 3.04 (95% CI:2.19, 4.22), hand washing after defecation 2.71 (95%CI:1.93, 3.82), hand washing after touching any body parts 2.41 (95%CI:1.64, 3.56), medical checkup 2.26, (95%CI:1.57, 3.25), food safety training 1.79 (95%CI: 1.30, 2.45) were factors significantly associated with intestinal parasitic infections.

Conclusion

In this study, intestinal parasitic infections among food handlers working in higher public university student’s cafeterias and public food establishment’s in Ethiopia were significantly high. Fingernail trimming, hand washing after defecation, hand washing after touching any body parts, regular medical checkup, and food safety training were significantly associated with intestinal parasitic infections.

Abstract
Background: The purpose of this study was to evaluate the value of Xpert MTB/RIF detection and tuberculosis antigen detection of Mycobacterium tuberculosis (MTB) in intestinal tissues for differentiating intestinal tuberculosis (ITB) from Crohn’s disease (CD).
Materials and Methods: A total of 110 patients who were clinically diagnosed with CD or ITB between January 2016 and March 2018 were initially enrolled in this study. The patients were monitored and their clinical, endoscopic and histopathological characteristics were followed up until their final diagnosis was clearly made. Several specimens of intestinal tissue from endoscopic biopsy or surgical excision were collected. One piece was used as paraffin specimen, and the other two pieces were used for MTB culture and Xpert MTB/RIF detection, respectively. Four antigens (38KDa protein, ESAT-6 protein, MPT64, Ag85 complex) of MTB in intestinal tissue were detected by immunohistochemistry.
Results: A total of 42 cases of intestinal tuberculosis and 46 cases of CD were included in the experimental analysis. Perianal lesions and longitudinal ulcers were more common in CD patients (p < 0.05), while caseous granuloma and annular ulcers were more common in ITB patients (P < 0.05). The positive rate of M. tuberculosis detected by Xpert MTB/RIF in intestinal tissue samples of ITB patients was 33.33%, which was significantly higher compared to CD patients (p < 0.05) and compared to acid-fast staining smears (9.52%) (p < 0.05). The positive MPT64 expression rate in patients with intestinal tuberculosis was 40.48%, which was significantly higher than that observed in CD patients, which was 19.56% (X2=4.61, p<0.05).
Conclusions: The detection of Xpert MTB/RIF in intestinal tissue was conducive to the quick and early diagnosis of intestinal tuberculosis. Xpert MTB/RIF and MPT64 antigen in intestinal tissues had certain value in the differential diagnosis of intestinal tuberculosis and Crohn’s disease. The combination of these two methods could improve detection sensitivity.

Published: August 2019

Abstract
• Background: Underlying mechanisms of non-specific chronic neck pain relapses are not clear, but it could be associated with a deficit and alteration of neck muscles propioception that play a decisive role in cervical joint position, motor control of the head and postural stability. Numerous treatments for non-specific chronic neck pain have been described in the scientific literature. However, few studies analyze its influence on postural stability, since these alterations are not fully described, and various theories emerge about the reasons that cause it. Our mainly aim is analyze the differences in postural stability, pain, cervical disability and the relation between them produced by a treatment based on manual therapy and other based on therapeutic exercise.
• Methods: The short-term and mid-term changes produced by different therapies on subjects with non-specific chronic neck pain will be studied. The sample will be randomly divided into three groups, manual therapy, therapeutic exercise and placebo. As dependent variables of the study, we will take: a) overall balance index, measured through a dynamic stabilometric platform; b) pain, based on the visual analog scale and the pressure pain threshold; c) cervical disability, through the cervical disability index. The findings will be analyzed statistically considering a 5% significance level (p ≤ 0.05)
• Discussion: Our study aims to provide knowledge about postural stability and its relationship with pain in subjects with non-specific chronic neck pain. Analyzing the results produced by different types of therapy will allow us to draw conclusions about the mechanisms that may elicit these alterations, structural or central mechanisms.

Authors: Svilović Sandra , Mužek Mario Nikola , Nuić Ivona , Vučenović Petra 
Published: August 2019

Abstract
The sorption of Cu ions on pure fly ash-based geopolymer, fly ash-based geopolymer with Pb ions addition (modified) and zeolite NaX was studied. Taguchi's approach was applied to determine the impact of solute concentration (c), temperature (T), mixing time (t) and sorbent type (S) on the sorption of Cu ions onto different sorbents under batch conditions. Optimum experimental conditions and influence of controllable factors were determined using the larger-the-better approach. The influence in descending order is c &gt; S &gt; t &gt; T, for both removal and loading. Also, the impact of sorbent type and solute concentration on the process equilibrium was examined. The equilibrium amount of Cu retained on the sorbents in equilibrium (qe) was as follows: pure geopolymer – 1.169 mmol g−1, modified geopolymer – 1.186 mmol g−1, and zeolite NaX – 1.695 mmol g−1. The experimental data were modelled using Jovanovic, Khan, Baudu, and Fritz-Schlünder isotherm models and their goodness of fit were compared. The Baudu isotherm model was the most useful in predicting the equilibrium of Cu sorption on pure and modified geopolymer. Goodness of fit of the selected isotherm models for the sorption of Cu ions on zeolite NaX was in the order: Fritz-Schlünder &gt; Khan &gt; Jovanovic &gt; Baudu.
Customer-Base Concentration, Investment, and Profitability: The U.S. Government as a Major Customer
Authors: Cohen Daniel A. , Li Bin 
Published: August 2019

ABSTRACT
We examine whether customer-base concentration has a differential impact on profitability for firms contracting with major government customers versus firms contracting with major corporate customers. We document that firm profitability increases with the concentration of major government customers, but decreases with the concentration of major corporate customers. We attribute the contrasting results to the differential impact of major government and corporate customers on demand uncertainty. Specifically, firms contracting with major government customers face lower demand uncertainty that enables them to realize more efficiency gains from customer-specific investments, whereas firms contracting with major corporate customers are exposed to higher demand uncertainty that reduces the efficiency of customer-specific investments. Overall, our study suggests that major government customers are unique and important in the composition of customer base, and they impact firm outcomes in a significantly different way than major corporate customers.

Published: August 2019

Penelitian ini bertujuan untuk mengkaji bagaimana pemenuhan hak perempuan dalam situasi bencana yang ada di Indonesia. Tindak penindasan lebih terlihat ketika sumber daya terbatas pada situasi bencana khususnya di negara berkembang atau daerah konflik. Hal ini menjadi penting meningat Indoensia adalah salah satu negara rawan bencana, dan disisi lain budaya patriarki yang telah mengakar sejak dulu masih menyisakan tindak diskriminasi bagi perempuan sehingga berimbas pda aspek-aspek pemenuhan hak-hak kelompok perempuan dalam situasi darurat seperti bencana. Maka pekerja sosial memiliki peran yang sangat dibutuhkan agar penyelesaian tidak hanya bersifat kuratif tetapi juga sensitif terhadap kebutuhan kelompok perempuan baik yang sudah tersuarakan maupun yang belum sehingga setiap kebutuhan dan pemenuhan hak perempuan korban bencana. Penelitian ini tidak hanya semata-mata sebagai bentuk perlawanan terhadap dominasi kelompok laki-laki, tetapi jalan advokasi untuk jaminan hidup yang aman dan nyaman bagi seluruh kelompok masyarakat. Artikel ini menggunakan metode studi pustaka yaitu buku dan jurnal. Hasilnya menunjukkan bahwa program penanggulangan bencana masih belum mengintegrasikan gender sebagai bagian komponen dari penyelenggaraan program penanggulangan bencana, sehingga hak-hak kelompok rentan seperti kelompok perempuan masih belum terpenuhi.
The three-way interplay of motor coordination, body fatness and physical activity in adolescents: a preliminary study
Authors: Chagas Daniel das Virgens , Batista Luiz Alberto 
Published: August 2019

Summary

Study aim: The purposes of this study were to analyze: the influence of physical activity level on the association between motor coordination and body fatness; the influence of body fatness on the association between motor coordination and physical activity; and how much physical activity and body fatness, separately and together, explain motor coordination in adolescent boys.

Material and methods: Fifty-one boys (n = 51), aged between 12 and 14 years, participated in the study. Motor coordination and physical activity and body fat percentage were assessed with, respectively, the Körperkoordinationstest für Kinder (KTK) and a validated self-administered questionnaire (PAQ-C). Skinfold thickness was measured to assess the participant’s body fat percentage. The Kruskal-Wallis test was performed to compare levels of motor coordination, physical activity, and body fat according to age (12, 13, 14 years). Bivariate and partial correlations were used to analyze the interrelationships among the selected variables.

Results: In the total studied group (n = 51 boys), motor coordination was positively associated with physical activity level (r = 0.300) and negatively associated with body fatness (r = –0.297). However, these associations were not statistically significant (p > 0.05) when controlled for body fatness and physical activity, respectively. Also, body fat and physical activity together explained 11% of the variance in the motor coordination level in adolescent boys.

Conclusions: These findings suggest that body fatness can influence the association between motor coordination and physical activity as well as that physical activity level can influence the association between motor coordination and body fat percentage. Also, body fat and physical activity together, but not separately, partially explained the variance in the motor coordination level. Therefore, body fat and physical activity seem to be complementarily associated with motor coordination in adolescent boys.

Summary

Study aim: The aim of the study was to investigate the relationship between attention and physical endurance (running) and anthropometric parameters of athletes.

Material and methods: The study examined 61 students aged 19 to 25 years, divided into two groups: athletes (33 participants) and non-athletes (28 participants). We employed anthropometric measurements and the Vienna System Test, including tools to measure focused attention, such as LVT (visual orientation performance test) and DAUF (test for examination of sustained attention) and the Cooper test to measure endurance.

Results: Analysis of the results demonstrated a relationship between attention and physical endurance with median time from LVT (r = –0.552). A relationship was also found between the Cooper test results and the mean time to incorrect answer (r = –0.900).

Conclusions: The analysis demonstrated a relationship between attention, physical endurance and anthropometric parameters of athletes.

Summary

Study aim: The aim of the present study was to compare the physiological responses of female soccer players recorded during the Beep Test and Yo-Yo Test.

Material and methods: Twenty-three high-level women’s soccer players underwent aerobic fitness testing. Modification of the Beep Test consisted of: lengthening the distance between turns to 40 m, extending the time between the increase in speed, and including a rest period between exercise stages. During the running efforts the length of the distance run in both tests was measured as well as circulatory and respiratory variables. For statistical analyses only data obtained at maximum loads in both tests were accepted.

Results: Analyzed variables showed that all values recorded in both tests reached maximum values and did not differ statistically significantly.

Conclusion: The results show that both applied tests loaded the soccer players to a similar maximum degree and the tests are suitable for assessing the aerobic physical performance.
In vitro interactions between Trichoderma harzianum and pathogenic fungi damaging horse-chestnut (Aesculus hippocastanum) leaves and fruits
Authors: Pastirčáková Katarína 
Published: August 2019

Abstract
Interactions between 3 pathogenic fungi damaging horse-chestnut (Aesculus hippocastanum) leaves and fruits – Phyllosticta sphaeropsoidea, Phomopsis carposchiza, and Diaporthe padi – and the antagonistic fungus Trichoderma harzianum were studied to determine their mutual influence in vitro. Antibiosis of colonies developing on 5 nutrient media was tested. The 3 studied T. harzianum isolates differed in their antagonistic potential. although T. harzianum isolates significantly inhibited the growth of Phomopsis carposchiza, the mycelium growth of some of the re-isolates on fresh medium indicates an inadequate antagonistic effect of T. harzianum on this species. The tested Trichoderma isolates showed stronger antagonism towards the other pathogens, reflected in overgrowing of Phyllosticta sphaeropso-idea and Diaporthe padi and reducing their growth. Granulation of the cytoplasm and lysis of hyphae of the fungal pathogens were the most frequently observed effects of the interaction.
