Authors: Shaat Emad A.A. , El-Sayed Mahfouz Amal , Dawood Abd El Ghaffar Saeed , Al Bohoty Shereen B. 
Published: February 2022

Background
Throughout gestation, iron requirements increase significantly to support a growing red cell volume, a developing fetus, and a developing placenta, and also any predicted or unplanned blood loss after birth, especially with cesarean delivery.

Aim
The scope of this study was to evaluate the occurrence of iron deficiency in the first trimester, in nonanemic pregnant women, and its relation to the outcome of pregnancy.

Patients and methods
This study was conducted on 100 pregnant women in the first trimester attending the Obstetric Department at Tanta University Hospital duration of research from October 2019 to October 2020, 4 ml of venous blood sample was collected, 2 ml was collected on EDTA vacutainers for complete blood picture, the other 2 ml was collected on plain tube for estimation of maternal serum iron, ferritin, centrifugated at high speed of 2000 rpm, and serum was stored at −20°C until analysis.

Results
This study was done on 100 cases to evaluate the frequency of iron deficiency in the first trimester, in nonanemic pregnant women and its relation on pregnancy.

Conclusion
Iron deficiency in gestation is indeed a common problem, according to this study, and it is largely linked to greater maternal per-partum morbidity. Pregnant women should really be encouraged to begin antenatal care as soon as possible, so that their hematological status can be adequately optimized through regular oral iron intake and/or parenteral iron supplementation ahead to labor and delivery, avoiding any need for blood transfusion.

Authors: Fayed Mostafa T.A. , Shehata Emad M. , Aglan Yasser I. , Albirmawy Osama A. 
Published: February 2022

Background
Bilateral abductor vocal fold paralysis (BAVFP) is an uncommon condition with potentially significant negative effects on breathing and quality of life. It presents as one of the most difficult problems for the laryngologist. Located at the crossroads of the airway and food passages, the larynx provides three important functions: airway protection, respiration, and phonation, which are affected by paralysis of one or both vocal folds.

Aims
The aims of treatment of BAVFP are to provide adequate airway, preservation of voice quality, and laryngeal competence.

Patients and methods
This is a randomized, prospective clinical trial that was carried out on 20 patients with BAVFP, who were subjected to endoscopic/assisted microscopic posterior cordotomy at the Department of Otorhinolaryngology, Tanta University Hospital. The study was carried out from first February 2019 till April 2020. The patients were allocated into two groups: group A patients were operated with radiofrequency. Group B patients were operated with monopolar microelectrodes. Grade of dyspnea, exercise tolerance test, voice handicap index-10, MD Anderson Dysphagia Inventory, and aspiration were evaluated preoperatively and 2 weeks and 3 months postoperatively.

Results
Both techniques were successful in postoperative glottic chink, exercise tolerance, dyspnea, and aspiration. There was a significant difference (P=0.007) between group A and group B at 3 months postoperative voice handicap index-10.

Conclusion
Both techniques could be used as an easy and cheap alternative in performing posterior transverse cordotomy.
Role of gray-scale ultrasound, Doppler, and ultrasound elastography in the evaluation of nodular goiter
Authors: Zaki Reem A. , Shehata Emad M. , Elsaed Haitham H. , Hegazy Hassan M. 
Published: February 2022

Background
Thyroid nodules are very common. Most nodules are benign, with less than 5% of them being malignant. High-resolution ultrasound (US) is sensitive in detection of thyroid nodules, enabling differentiation of solid and cystic lesions. Conventional US does not provide information regarding hardness of the nodule and this is often the role of Ultra Sound Elastography (USE). US elastography was developed to work out tissue stiffness and strain information noninvasively.

Aim
The aim was to judge of the accuracy of gray-scale US, Doppler, and US elastography in the diagnosing of nodular thyroid diseases.

Patients and methods
The study included 20 consecutive patients with a clinically diagnosed multinodular goiter presented to Otorhinolaryngology OutPatient Clinic. All patients have been subjected to detailed history taking, complete Oto Rhino Laryngology (ORL) head and neck examination, complete general examination, and routine investigations for general anesthesia. Radiological imaging using conventional US and real- time US, Doppler study of the whole thyroid gland by the same probe, and elastography. Suspicious nodules were subject to Fine Needle Aspiration Cytology (FNAC) and surgery was done by ORL surgeon in the ENT department.

Results
In this study, 20 cases were included from which 19 cases were benign and only one case was malignant. There was a high statistical significance in-between the US classification and elasticity score with P less than 0.001, and high statistical significance in-between Doppler signs and elasticity score with P less than 0.001.

Conclusion
US elastography may be a promising technique that combined with other US modalities is straightforward and rapid to perform and might help to spot thyroid nodules that are likely to be malignant.
Evaluation of effluent post-treatment by slow filtration and adsorption with activated carbon produced from spent coffee grounds in surfactant removal in sewage treatment
Authors: Ribeiro Marcelo Pinheiro , Botari Alexandre 
Published: February 2022

Environmental pollution is a worldwide concern, especially when caused by sewage dumping into water bodies. Many substances are present in industrial or domestic wastewater, causing contamination in superficial water collection. Surfactants stand out for being widely used both industrially and domestically. The use of detergents and many types of surfactants was increased during the Covid-19 pandemic period, a fact observed in the levels in the effluent sample analysis from a Sewage Treatment Plant (STP) - Vila City around 21 and 39 mg L-1 in this period. This work evaluated the surfactant concentrations in the primary and secondary treatment units of the Vila City STP, in the city of Paranavaí-PR.-Brazil. In addition, the use of a post-treatment by slow sand filtration and adsorption by activated carbon produced from spent coffee grounds in the complementary removal of surfactants was proposed. A mixed bed with sand and activated carbon columns was made on a pilot scale, and filtration/adsorption runs were performed simulating slow filtration with rates of approximately 15 m3 m-2 day-1. The parameters used for the efficiency removal evaluation in a pilot plant run were: turbidity (NTU) and surfactant concentrations. The removal of surfactant concentrations was about 9% and 7% in the Upflow Anaerobic Sludge Bed reactors (UASB-RALF) and in the secondary treatment, respectively, at the STP – Vila City units. In the post-treatment proposed by filtration/adsorption, bed columns on a pilot scale plant obtained a reduction of approximately 94% in terms of turbidity (NTU) and 95% in terms of surfactant removal.

Surface retention of polyurethane and acrylic coatings on impregnated spruce wood (Picea abies Karst) and comparison with some wood preservatives
Authors: Bahchevandziev Konstantin , Mihajlovski Nikola 
Published: February 2022

The natural spruce wood has low resistance against biological degradation and weather effects, so further protection is required, up to meeting the durability requirements for wood used in exterior classes. According to the wood preservatives standards, coatings as water repellents belong to the group OS (organic solvent) preservatives. The coatings have a water-repellent function, and they are not toxic, so these advantages make them usable like impregnation material. The objective of this work is impregnation of the spruce wood (Picea abies Karst) using the “Double vacuum process” with coating material based on polyurethane and acrylic isocyanate resins and determinate the coatings quantity in wood. The impregnation efficiency is expressed through the retention. The coatings retention is compared with the minimal standard prescribed retention of the preservatives, most frequently used, namely creosote, copper chrome arsenate (CCA) and waterborne copper-rich systems like copper azole (CBA-A, Thanalite E), to show the efficiency of the applied double vacuum process. The coating retention is not significantly different from the minimum prescribed retention of creosote and amounts 118 - 149 kg/m3 or 32 to 38 times higher than the recommended retention of CCA or CBA-A for wood protection in the exterior use. The polyurethane and acrylic wood coatings can be successfully applied for wood impregnation purposes. Key words: impregnation, retention, spruce wood, polyurethane coatings, acrylic isocyanate coatings.

Published: February 2022

Modification by physical and chemical treatments was evaluated to increase the adsorption capability of natural pumice in the removal of Cu(II) from aqueous solution. The treatments were heating at temperatures of 300, 450 and 600 ℃ for physical and soaking in acid solutions (HCl, H2SO4 and HNO3) for chemical treatment. The adsorption was performed in the batch system at the optimum condition (5 of pH solution, < 63 µm of adsorbent diameter, 3 g/L of adsorbent dose, 5 mg/L of Cu(II) concentration and 30 min of contact time). The results showed the removal efficiency and Cu(II) uptake increased using modified pumice from 71.19 % and 1.19 mg/g to 84.45 % and 1.41 mg/g. The highest removal efficiency and Cu(II) uptake were obtained from 300℃ of heating temperature and HCl for the acid solution. The application of physical and chemical treatments in modification has the potential to increase the removal efficiency and heavy metal uptake of the natural pumice.
HIGHLIGHTS

Various methods have been evaluated for the modification of pumice to improve their sorption capacity
Physical and chemical treatment to pumice may modify the surface areas, pore structures, and chemical functional group on the surface of the pumice

The body as a reflection of relations with others
Authors: J. Lammek Mateusz 
Published: February 2022

IntroductionCorporeality is an important element of the self structure. Tattoos have been associated with self-esteem, identity diffusion, and aggression.Material and methodsConvicted modified (n = 78; 78.8%) and non-modified men (n = 21; 21.2%) completed the following research tools: the Aggression Severity Scale from the Inventory of Personality Organization (IPO), the Group Identification Scale, the Identity Fusion Scale, a measure of identity fusion, and an agency scale.ResultsBody modifications were a weak predictor (5%) of aggression intensity among male prisoners. About 20% of the study participants, regardless of having a body modification, presented aggression characterized by severe personality pathology.ConclusionsNowadays, body modifications should not be treated as an indicator of severe psychopathology and more aggressive relations with others, including among convicted men. In prisoners who presented high levels of aggression, identity diffusion was observed and treated as a form of adaptation, characteristic for borderline personality integration.

IntroductionTo evaluate the relationship between lymphedema, posture, respiratory functions, exercise capacity, and the quality of life after breast cancer treatment.MethodsThis cross-sectional study consisted of 38 women who had unilateral breast cancer treatment. Pulmonary function with a spirometer, functional exercise capacity via 6-minute walking test, postural alignment changes, and quality of life were evaluated. Circumferential measurements were used to determine the severity of lymphedema.ResultsThe median age of female participants was 53 years (range, 40–64). The mean body mass index was 26.66 ± 2.96 kg/m<sup>2</sup>, of which 76% had lymphedema. The expected changes in posture were moderate. The mean of the 6-minute walking distance decreased, which corresponded to 58.55% of normative values. MIP and MEP values were significantly lower than expected values. An intermediate negative correlation was observed between postural changes and body mass index (<i>r</i> = –0.348; <i>p</i> = 0.05). Moreover, there was a positive correlation between forced expiration volume and forced vital capacity values and walking distance (<i>p</i> < 0.05).ConclusionAfter breast cancer treatment, 76% of female patients had lymphedema, the functional exercise capacity, MIP and MEP were below the expected values in all of them, and as functional capacity decreases, respiratory parameters affected negatively.

Abstract. Terrestrial mud volcanoes (MVs) represent the surface
expression of conduits tapping fluid and gas reservoirs in the deep
subsurface. Such plumbing channels provide a direct, effective means to
extract deep microbial communities fueled by geologically produced gases and
fluids. The drivers accounting for the diversity and composition of these
MV microbial communities, which are distributed over a wide geographic range, remain
elusive. This study characterized the variation in microbial communities in
15 terrestrial MVs across a distance of ∼ 10 000 km on the
Eurasian continent to test the validity of distance control and
physiochemical factors in explaining biogeographic patterns. Our analyses
yielded diverse community compositions with a total of 28 928 amplicon
sequence variances (ASVs) taxonomically assigned to 73 phyla. While no true
cosmopolitan member was found, ∼ 85 % of ASVs were confined
within a single MV. Community variance between MVs appeared to be higher and
more stochastically controlled than within MVs, generating a slope of the
distance–decay relationship exceeding those for marine seeps and MVs as well as
seawater columns. For comparison, physiochemical parameters explained 12 %
of community variance, with the chloride concentration being the most
influential factor. Overall, the apparent lack of fluid exchange renders
terrestrial MVs a patchy habitat, with microbiomes diverging stochastically
with distance and consisting of dispersal-limited colonists that are highly
adapted to the local environmental context.
