Comparative Clinical Effects of Early Pharyngostomy Alimentation and Intravenous Fluid Infusion following Oesophageal Transection and Anastomosis in Nigerian Breeds of Dogs
Authors: Omamegbe J.O , Njoku U.N , Ibup S.E 
Published: May 2021

Twelve adult Nigerian breeds of dogs were used to compare the clinical responses of dogs alimented through pharyngostomy tubes (PGTs) with those maintained on intravenous infusion (50:50 mixture of Ringers lactate and 5% dextrose saline) during the first 14 days following oesophageal transection and anastomosis (OTA). The dogs were assigned to two groups (n=6), the pharyngostomy tube (PGT) group and the intravenous fluid infusion (IVF) group (n=6). Dogs in both groups underwent routine OTA. The PGT group was fed blanched processed dog food at 70g/kg body weight for 14 days through PGTs, while the IVF group was maintained on intravenous fluids at a dose of 70 mL/kg body weight daily also for 14 days post operatively. The postoperative complications observed in both groups showed that the mortality rate in the IVF group (83.3%) was significantly (P < 0.05) higher than in the PGT group (16.7%). Vomiting and leakages at the site of oesophageal anastomosis did not differ significantly between the groups. Cervical swelling was observed in two dogs (33.3%) in the IVF group, while tenesmus and displacement of the tubes were recorded in 66.6% and 100% respectively of the dogs in the PGT group. It is concluded that feeding dogs which had undergone OTA through PGTs during the immediate postoperative period reduces their morbidity and mortality; and shortens the recovery period when compared with similar dogs maintained solely on intravenous fluids.

A rare case of equine Haemotropic Mycoplasma infection in Nigeria
Authors: Happi A.N , Oluniyi P.E 
Published: May 2021

Equine haemotropic mycoplasmosis (EHM) is a condition rarely reported worldwide. A horse presented with unspecific clinical findings and non-response to treatment to the common and endemic haemoparasitic and bacterial infections, warranted a thorough molecular investigation of suspected haemoparasitic infection given the fluctuating parasitaemia and the low sensitivity and specificity of Light Microscopy (LM) detection of haemoparasitic infections. Blood collected from an adult horse, domiciled at the University of Ibadan Veterinary Teaching Hospital, Ibadan, Nigeria was screened by LM and PCR techniques for haemo-parasites. The 16S rRNA gene of pan-Hemoplasma spp was targeted amplified and sequenced using Sanger automatic sequencing techniques. This case shows the very first molecular evidence of EHM in Africa and Nigeria, and the third case in the World. Microscopic examination of the horse’s blood smear presented with signs of lethargy, inactivity, anorexia and moderate emaciation, showed numerous coccoid-shaped epierythrocytic parasites. Subsequent 16S rRNA sequence data and phylogenetic analyses confirmed the presence of a haemotropic mycoplasma (‘Candidatus M. haemocervae’–like) in the horse. The hemoplasma sequence obtained falls in the same clade with some Candidatus Mycoplasma haemocervae sequences with which it shared more than 98.7% homology. This finding suggests that horses in this geographical region may also be suffering from EHM and calls for the need of epidemiological surveillance of equine hemoplasmosis with emphasis on their clinical, economic, performance and zoonotic implications in the sub-region.

Published: May 2021

The study presented the results obtained from estimation of the depth to the bsement bedrock (overburden thickness) in Olabisi Onabanjo University, Ago-Iwoye using two configurations of electrical resistivity methods. The study was aimed to delineate the stratigraphy and thicknesses of the subsurface layer present in the study area for comprehensive study of the lithostratigraphic information of the area. Vertical Electrical Sounding (VES) and 2-D Horizontal Electrical Profiling (HEP) techniques were used to obtain 1-D and 2-D subsurface resistivity images of the study area. The VES data were plotted manually on the Bi-log graph. The curve obtained was partially curve – matched to obtain the layer resistivities and thicknesses for further iteration. The 2-D resistivity imaging data were analyzed and processed to obtain the inverted (true) resistivity image. From the results, five (5) VES type curves weredelineated. These includes H, HA, QH and KH type. The geoelectric sections and 2-D resistivity images showed three to four geoelectric layers. These layers are topsoil/laterite, weathered basement, partly weathered/fractured basement and fresh basement. The study showed that materials with resistivity values that ranged between 10 and 298 Ωm and 152 and 589 Ωm representing clayey weathered layer and partly weathered/fractured basement were delineated beneath some sounding points. The clayey and weathered layer are indicative of soil formations that are inimical to foundation of civil engineering structure. Likewise, they can serve as reservoir for groundwater potential (if the porosity and permeability are high). Due to this, detailed lithostratigraphic evaluation through petrophysical analysis is encouraged for the purpose of mapping and correlation of the rock units before embarking on any engineering construction in the study area. The study concludes in providing assistance to subsequent research on the stratigraphic related studies in the area.

Impact of acid activated Bentonites on foster swelling capacity and sorption dynamics of hydrocarbons, phenol and water
Authors: Chukwu U.J. , Okoye I.P. , Awosu E.I. 
Published: May 2021

The successful protonation of the dissociable 𝐻 + from different organic acids (with varying alkyl chains) to supplant sodium ions in the inter layers of bentonites resulting in increased surface area has been carried out. The resultant materials were characterized using foster swelling and adsorption capacity techniques. Results show that the foster capacities of acid activated bentonites were greater than the un-activated bentonite (UAB) upon interaction with petroleum hydrocarbons. The bentonite activated with the organic acid having the most alkyl chain, hexanoic acid activated bentonite (HAAB) showed high affinity for all petroleum hydrocarbons. This demonstrates the hydrophilicity of UAB and upon activation, the hydrophobic properties of HAAB. The adsorption capacity result records that bentonites and HAAB adsorbed more petroleum hydrocarbon solvents than other lower alkyl chain acid activated bentonites and UAB. This study shows that HAAB is an excellent adsorbent for the removal of hydrocarbons from industrial wastes.

A climate index for the Newfoundland and Labrador shelf
Authors: Cyr Frédéric , Galbraith Peter S. 
Published: May 2021

Abstract. This study presents in detail a new climate index for the Newfoundland and Labrador (NL) shelf.
The NL climate index (NLCI) aims to describe the environmental conditions on the NL shelf and in the Northwest Atlantic as a whole.
It consists of the average of 10 normalized anomalies, or subindices, derived annually: winter North Atlantic Oscillation, air temperature, sea ice season severity, iceberg count, seasonal sea surface temperature, vertically averaged temperature and salinity at the Atlantic Zone Monitoring Program (AZMP) Station 27, summer cold intermediate layer (CIL) core temperature at AZMP Station 27, summer CIL area on three AZMP hydrographic sections, and bottom temperature on the NL shelf.
This index runs from 1951 to 2020 and will be updated annually.
It provides continuity in the production of advice for fisheries management and ecosystem status on the NL shelf, for which a similar but recently abandoned index was used.
The new climate index and its subindices are available at https://doi.org/10.20383/101.0301 (Cyr and Galbraith, 2020).

Gold Deposits of the ~15-Moz Ahafo South Camp, Sefwi Granite-Greenstone Belt, Ghana: Insights into the Anatomy of an Orogenic Gold Plumbing System
Authors: Masurel Quentin , Morley Paul , Thébaud Nicolas , McFarlane Helen 
Published: May 2021

Abstract
The ~15-Moz Ahafo South gold camp is located in southwest Ghana, the world’s premier Paleoproterozoic gold subprovince. Major orogenic gold deposits in the camp include Subika, Apensu, Awonsu, and Amoma. These deposits occur along an ~15-km strike length of the Kenyase-Yamfo shear zone, a major tectonostratigraphic boundary juxtaposing metamorphosed volcano-plutonic rocks of the Sefwi belt against metamorphosed volcano-sedimentary rocks of the Sunyani-Comoé basin. In this study, we document the geologic setting, structural geometry, and rheological architecture of the Ahafo South gold deposits based on the integration of field mapping, diamond drill core logging, 3-D geologic modeling, and the geologic interpretation of aeromagnetic data. At the camp scale, the Awonsu, Apensu, and Amoma deposits lie along strike from one another and share similar hanging-wall plutonic rocks and footwall volcano-sedimentary rocks. In contrast, the Subika gold deposit is hosted entirely in hanging-wall plutonic rocks. Steeper-dipping segments (e.g., Apensu, Awonsu, Subika) and right-hand flexures (e.g., Amoma, Apensu) in the Kenyase-Yamfo shear zone and subsidiary structures appear to have represented sites of enhanced damage and fluid flux (i.e., restraining bends). All gold deposits occur within structural domains bounded by discontinuous, low-displacement, sinistral N-striking tear faults oblique to the orogen-parallel Kenyase-Yamfo shear zone. At the deposit scale, ore-related hydrothermal alteration is zoned, with distal chlorite-sericite grading into proximal silica-albite-Fe-carbonate mineral assemblages. Alteration halos are restricted to narrow selvages around quartz-carbonate vein arrays in multiple stacked ore shoots at Subika, whereas these halos extend 30 to 100 m away from the ore zones at Apensu and Awonsu. There is a clear spatial association between shallow-dipping mafic dikes, mafic chonoliths, shear zones, and economic gold mineralization. The abundance of mafic dikes and chonoliths within intermediate to felsic hanging-wall plutonic host rocks provided rheological heterogeneity that favored the formation of enhanced fracture permeability, promoting the tapping of ore fluid(s). Our interpretation is that these stacked shallow-dipping mafic dike arrays also acted as aquitards, impeding upward fluid flow within the wider intrusive rock mass until a failure threshold was episodically reached due to fluid overpressure, resulting in transient fracture-controlled upward propagation of the ore-fluid(s). Our results indicate that high-grade ore shoots at Ahafo South form part of vertically extensive fluid conduit systems that are primarily controlled by the rheological architecture of the rock mass.
Una construccion compleja de la interfase territorial. revisión conceptual para la generación de variables de análisis
Authors: Céliz Yuliana 
Published: May 2021

La expansión de las ciudades como antropización del territorio implica impactos en la dinámica de usos del suelo. Esto se da por interacción de sistemas más o menos naturales afectados y se observa en la sustitución de coberturas de suelo. El espacio en el que se intensifica es la interfase. Una construcción compleja del concepto interfase servirá para identificar variables de gran intensidad de interacción y que implican impacto territorial. El objetivo de este trabajo fue la revisión crítica de investigaciones que permitieron identificar dichas variables para su espacialización. Se revisaron un total de 60 papers, producidos desde la revolución industrial, a partir de 3 enfoques: urbano, rural y natural. La sistematización se realizó a través de un software estadístico que determinó elementos comunes y relaciones entre las definiciones. Los resultados arrojaron que la mayoría de las teorías actuales provienen de países americanos y la India y que, los trabajos europeos, fueron publicados entre 10 y 15 años antes que estos. La mayor cantidad de producción sobre el análisis de interfase aún está asociada al Urbanismo. Asimismo, se destacaron variables relevantes que ubicaron al fenómeno entre la escala urbana y la regional como paradigma territorial.
The cities expansion as a territory anthropization implies impacts in the land use dynamics. This occurs through the interaction between more or less natural affected systems and can be detected in the substitution of land cover. The space in which it intensifies is the interface. A complex construction of the interface concept will serve to identify variables of high intensity of interaction involving territorial impact. The objective of this work was the critical review of research that enabled identification of such variables for their spatialization. A total of 60 papers, produced since the industrial revolution, were reviewed using 3 approaches: urban, rural and natural. The systematization was carried out through statistical software that determined common elements and relationships between definitions. The results indicated that most of the current theories come from American countries and India and that the European papers were published 10-15 years earlier than these. The greatest amount of production on interface analysis is still associated with Urbanism. Furthermore, relevant variables were highlighted that located the phenomenon between the urban and regional scales as a territorial paradigm.

Authors: Yang Fen , Zhang Yuanyue , Qiu Ruiying , Tao Ning 
Published: May 2021

Objective
The aim of this study is to explore sleep status and hypertension among oil workers in Xinjiang, China. It may provide new ideas and basis for the precise prevention and treatment of hypertension in occupational population.

Methods
Sleep status and hypertension were investigated in 3,040 workers by a multi-stage cluster sampling method in six oil field bases in Karamay City, Xinjiang. The Pittsburgh Sleep Quality Index was used to evaluate the sleep status of workers. Logistic regression was used to analyze the relationship between sleep duration and sleep quality, and hypertension. Stratified analysis was also performed.

Results
Our results show: 1. Insufficient sleep duration (OR = 1.51, 95% CI [1.19–1.90]) and poor sleep quality (OR = 1.78, 95% CI [1.33–2.38] were positively associated with hypertension. 2. Stratified analysis indicated insufficient sleep duration was associated with increased risk of hypertension in females (OR = 1.54, 95% CI [1.16–2.04]) than males (OR = 1.49, 95% CI [1.00–2.23]), and the risk of hypertension in the group <30 years old (OR = 9.03, 95% CI [2.32–35.15]) was higher than that in the group of 30–45 years old (OR = 1.59, 95% CI [1.14–2.20]). However, in the group > 45 years old, sleeping > 8 h was associated with increased risk of hypertension (OR = 3.36, 95% CI [1.42–7.91]). Oil workers doing shift work had a higher risk of hypertension (OR = 1.55, 95% CI [1.16–2.07]) to no shift work (OR = 1.48, 95% CI [1.02–2.15]). The risk of hypertension in the group with < 10 years of service (OR = 4.08, 95% CI [1.92–8.83]) was higher than that in the group with length of service of 10–20 years (OR = 2.79, 95% CI [1.59–4.86]). Poor sleep quality was associated with risk for hypertension in females (OR = 1.78, 95% CI [1.26–2.49]), those doing shift work (OR = 1.70, 95% CI [1.17–2.47]), those with length of service of > 20 years (OR = 1.64, 95% CI [1.18–2.27]). The risk of hypertension in the group 30–45 years old is higher than that in the group > 45 years old (OR 30–45 years old = 1.71, 95% CI [1.10–2.66]; OR > 45 years old = 1.60, 95% CI [1.09–2.34]).

Conclusion
Insufficient sleep duration and poor sleep quality are the potential factors affecting hypertension in Xinjiang oil workers.
Outcomes of critically ill end-stage kidney disease patients who underwent major surgery
Authors: Petchmak Peerawitch , Wongmahisorn Yuthapong , Trongtrakul Konlawij 
Published: May 2021

Purpose
End-stage kidney disease (ESKD) is a major worldwide health problem. Patients with ESKD are thought to have a significant risk for development of complications following an operation. However, the study of ESKD and its outcomes following major operations remains rare, particularly in critical illness. Therefore, this study aimed to demonstrate how the outcomes of ESKD patients were affected when they underwent a major operation and were admitted to the intensive care unit (ICU), compared with non-ESKD patients.

Methods
A retrospective matched case cohort study was conducted in 122 critically ill surgical patients who underwent a major operation and were admitted to the ICU, during 2013 and 2016. Sixty-one ESKD patients who required long-term dialysis were enrolled and compared with 61 matched non-ESKD patients. The matching criteria were the same age interval (±5 years), gender, and type of operation. The ICU mortality was compared to the primary outcome of the study.

Results
Patients’ baseline characteristics between ESKD and non-ESKD were similar to a priori matching criteria and other demographics, except for pre-existing diabetes mellitus and hypertension, which were found significantly more in ESKD (p = 0.03 and 0.04, respectively). For operations, ESKD showed a higher grade of the American Society of Anesthesiologist (ASA) physical status (p < 0.001), but there were no differences for emergency surgery (p = 0.71) and duration of operation (p = 0.34). At ICU admission, the severity of illness measured by the Sequential Organ Failure Assessment (SOFA) score was greater in ESKD (8.9 ± 2.6 vs 5.6 ± 2.5; p < 0.001). However, after eliminating renal domain, SOFA non-renal score was equivalent (5.7 ± 2.2 vs 5.2 ± 2.3, p = 0.16). The ICU mortality was significantly higher in critically-ill surgical patients with ESKD than non-ESKD (23% vs 5%, p=0.007), along with hospital mortality rates (34% vs 10%, p = 0.002). The multivariable logistic regression analyses adjusted for age and SOFA non-renal score demonstrated that ESKD had a significant association with ICU and hospital mortality (adjOR = 5.59; 95%CI [1.49–20.88], p = 0.01 and adjOR = 4.55; 95%CI[1.67–12.44], p = 0.003, respectively).

Conclusion
Patients who underwent a major operation and needed intensive care admission with pre-existing ESKD requiring long-term dialysis were associated with greater mortality than patients without ESKD. More careful assessment before, during, and after major surgical procedures should be performed in this group of patients to improve post-operative outcomes.

Background
High-throughput sequencing platforms generate a massive amount of high-dimensional genomic datasets that are available for analysis. Modern and user-friendly bioinformatics tools for analysis and interpretation of genomics data becomes essential during the analysis of sequencing data. Different standard data types and file formats have been developed to store and analyze sequence and genomics data. Variant Call Format (VCF) is the most widespread genomics file type and standard format containing genomic information and variants of sequenced samples.

Results
Existing tools for processing VCF files don’t usually have an intuitive graphical interface, but instead have just a command-line interface that may be challenging to use for the broader biomedical community interested in genomics data analysis. re-Searcher solves this problem by pre-processing VCF files by chunks to not load RAM of computer. The tool can be used as standalone user-friendly multiplatform GUI application as well as web application (https://nla-lbsb.nu.edu.kz). The software including source code as well as tested VCF files and additional information are publicly available on the GitHub repository (https://github.com/LabBandSB/re-Searcher).
