Authors: Passawart Nattapon , Rungsrithananon Warit , Jaseanchiun Warakon 
Published: September 2021

Abstract
Background:
Morbidity and mortality after pancreaticoduodenectomy (PD) have been associated with postoperative pancreatic fistula (POPF). Pancreatic anastomosis is challenging for most surgeons, and there is no universal or standardized technique. This study compared the incidence of POPF between the pair-watch suturing technique (PWST) and duct-to-mucosa pancreaticojejunostomy (PJ) anastomosis technique.
Methods:
This retrospective cohort analysis included 71 patients who underwent a PD between January 2009 and October 2018. The incidence and risk factors of complications after PWST and duct-to-mucosa PJ anastomoses were compared.
Results:
There was no significant difference in the incidence of POPF between the PWST (n = 7; 30.4%) and duct-to-mucosa PJ (n = 9; 18.7%) groups. The tumor site (p = 0.001) and pancreas density on computed tomography without contrast (p = 0.002) were significantly different between the groups. Age ≥ 60 years (odds ratio (OR): 11.07; 95% confidence interval (CI): 1.14–107.36; p = 0.038) and pancreatic body mass/duct size (B/W) ratio (OR: 1.41; 95% CI: 1.04–1.91; p = 0.029) were identified as significant risk factors for POPF. International Study Group for Pancreatic Fistula grade B POPF, wound infections, and pneumonia occurred more frequently in patients who underwent a duct-to-mucosa PJ anastomosis. However, the postoperative complications were not significantly different between the groups.
Conclusions:
The incidence of clinically relevant POPF was similar between patients who underwent the PWST and those who underwent a duct-to-mucosa PJ anastomosis. However, a preoperative risk factor assessment for the evaluation of tumor site, patient age, and B/W ratio could help determine which surgical technique should be used in individual patients.

Published: September 2021

Abstract
Traditional finishing technology is difficult to realize the precision machining of complex geometric parts. Abrasive flow machining technology solves this problem well. Taking the spur internal gear as the research object, the wall shear force, static pressure, dynamic pressure and abrasive velocity vector of the internal channel of the straight internal gear under different inlet velocity, abrasive concentration and abrasive particle size are analyzed by using the large eddy simulation method, and the action law of different parameters on the machining of straight internal gear by solid-liquid two-phase abrasive flow is discussed. At the same time, orthogonal test was carried out. The results show that the solid-liquid two-phase abrasive flow machining technology can effectively remove the burrs, pits and bulges on the tooth surface of spur internal gear, reduce the tooth surface roughness and improve the surface quality. The optimal combination of processing parameters and the primary and secondary order of various factors affecting processing are obtained by range analysis and analysis of variance. The regression equation is constructed by regression analysis to verify the effectiveness and accuracy of the model, which provides theoretical support and data reference for actual processing and production.

Abstract
Background
Burkina Faso has one of the highest malaria burdens in sub-Saharan Africa despite the mass deployment of insecticide-treated nets (ITNs) and use of seasonal malaria chemoprevention (SMC) in children aged up to 5 years. Identification of risk factors for Plasmodium falciparum infection in rural Burkina Faso could help to identify and target malaria control measures.
Methods
A cross-sectional survey of 1,199 children and adults was conducted during the peak malaria transmission season in south-west Burkina Faso in 2017. Logistic regression was used to identify risk factors for microscopically confirmed P. falciparum infection. A malaria transmission dynamic model was used to determine the impact on malaria cases averted of administering SMC to children aged 5–15 year old.
Results
P. falciparum prevalence was 32.8% in the study population. Children aged 5 to < 10 years old were at 3.74 times the odds (95% CI = 2.68–5.22, p < 0.001) and children aged 10 to 15 years old at 3.14 times the odds (95% CI = 1.20–8.21, p = 0.02) of P. falciparum infection compared to children aged less than 5 years old. Administration of SMC to children aged up to 10 years is predicted to avert an additional 57 malaria cases per 1000 population per year (9.4% reduction) and administration to children aged up to 15 years would avert an additional 89 malaria cases per 1000 population per year (14.6% reduction) in the Cascades Region, assuming coverage of pyrethroid-piperonyl butoxide ITNs.
Conclusion
Malaria infections were high in all age strata, although highest in children aged 5 to 15 years, despite roll out of core malaria control interventions. Given the burden of infection in school-age children, extension of the eligibility criteria for SMC could help reduce the burden of malaria in Burkina Faso and other countries in the region.

Published: September 2021

Abstract
The Bacillus velezensis YYC strain was isolated from the tomato rhizosphere. In a previous experiment, it increased tomato growth and induced systemic resistance against Ralstonia solanacearum. However, information on its genomic content is lacking. The complete genome sequence of the bacterium was described in this study. The genome size was 3,973,236 bp and consisted of 4,034 genes in total, with a mean G + C content of 46.52%. 86 tRNAs and 27 ri-bosome RNAs were identified. 14 clusters of secondary metabolites were identified. The KEGG database analysis showed that 69 genes were related to quorum sensing, which were important for cross-kingdom communication. In addition, genes involved in promoting plant growth and triggering plant immunity were identified from the genome. Based on digital DNA–DNA hybridizations (dDDH), B. velezensis YYC was the most closely related with B. velezensis FZB42. However, compared with B. velezensis FZB42, the lantipeptide biosynthesis gene cluster was special and only existed in the genome of B. velezensis YYC. The complete genome data of B. velezensis YYC will provide a basis for explanation of its growth-promoting mechanism and biocontrol mechanism.

Published: September 2021

Abstract
This study aims at integration of magnetic and vertical electrical sounding (VES) resistivity methods to determine groundwater prospective in part of Aran-orin Sheet 224. A total of three traverses were established in the study area for the vertical electrical sounding using the Schlumberger electrode configuration. A total of 17 VES points was established using the ABEM Terrameter SAS 1000C model with maximum half-current electrode spacing (AB/2) of 120m. A total of eight traverses were established for the magnetics survey with station intervals of 10 m and inter-profile spacing of 100 m. The magnetic and VES data were qualitatively and quantitatively interpreted using IPI2WIN and OASIS MONTAJ package respectively. The geo-electric sections reveal a maximum of 3–4 layers beneath the sub-surface an overburden thickness ranges from 8.2 m to 64.9 m and the corresponding lithology inferred are topsoil, weathered Rock, fractured basement and fresh basement. The depth to basement using half-width method showed that the depth ranges from 8.4-56.04 m, which corresponds with the electrical survey.
Embolization of a Mesenteric Arteriovenous Malformation Associated with Idiopathic Myointimal Hyperplasia: A Case Report and Literature Review
Authors: Shah Yash B , Lee Derek , Khaddash Tamim S. 
Published: September 2021

Abstract
Background

Idiopathic myointimal hyperplasia of the mesenteric vein (IMHMV) is a rare, often undiagnosed pathology affecting the colon. Patients typically present with severe abdominal pain and inflammation caused by smooth muscle proliferation of the veins, leading to arterialization, stenosis, and potential occlusion. The etiology remains unclear, but it has been hypothesized that an arteriovenous connection may be associated with the pathology. This is the first reported case supporting such an association. Endovascular embolization is generally a less invasive alternative to surgical resection in the treatment of such vascular disorders, and our case highlights the potential benefits of endovascular treatment.

Case Presentation

This report describes a 24-year-old female patient with findings of colitis and an abnormal arteriovenous connection of the inferior mesenteric arterial and venous system. Partial embolization of this arteriovenous connection temporarily improved symptoms, but the presence of multiple smaller feeder vessels not amenable to embolization ultimately necessitated colonic resection for definitive treatment. Although prior reports have hypothesized that arterial pressurization of the veins may cause myointimal hyperplasia, to the authors’ knowledge, this is the first report of IMHMV with an associated abnormal arteriovenous connection.

Conclusions

This case illustrates the possibility of a pathogenic relationship between an arteriovenous connection and IMHMV. It is presumable that early radiologic analysis for an abnormal arteriovenous connection in colitis patients may facilitate IMHMV diagnosis, and early diagnosis may even facilitate the success of embolization.
Evaluation of Long-term Oncological Outcomes of Inter-Sphincter Resection Compared with Traditional Abdominoperineal Resection in Treatment of Low Rectal Cancers: A Cross Sectional Study
Authors: Anaraki FakhroSadat , Alemrajabi Mahdi , Shekouhi Ramin , Sohooli Maryam , Sabz Seyed-Ali 
Published: September 2021

Abstract
Objectives

abdominoperineal resection (APR), is considered the gold standard surgical treatment for low rectal cancer. Patients with low rectal tumors, tumor’s distance less than 5 cm from the anal verge, are likely to require permanent colostomy after APR. Thus, anus-preserving alternative procedures have been tested to avoid the need for permanent colostomy. the aim of the present study is to compare the functional results, and oncological outcome of traditional APR method.
Methods

Patients' demographic information as well as tumor characteristics were evaluated through a patient's information form. All patients were followed after the operation every three months for two years, and then every six months for at least three years.
Results

The study was performed on 60 patients with rectal cancer. In the group that performed APR, 9 (30%) patients developed with disease recurrence. In the ISR group, 10 (33.3%) had relapses. Based on this result, the two groups were nearly similar in the recurrence rate of disease and the difference between these two groups was not statistically significant (P value = 0.8).
Conclusion

In summary, the results of the present study concluded that there is no significant difference in efficacy of ISR method compared with the conventional APR in treatment of ultra-low rectal cancer. We surveyed that the ISR method is associated with beneficial long-term survival. Considering the post-operation complication associated with APR surgery including permanent colostomy, and disappointing functional outcomes, we encourage physicians to expand the use of anus-preserving procedures in treatment of low-grade distal rectal cancer.

Abstract

This paper presents a unique study to reveal the effect of the mounting system of the linear variable differential transformer (LVDT) on the mechanical property tests of timber materials. This effect has been overlooked in the past but proven to be significant enough that will distort the measurements completely if the displacement is relatively small. The reason for causing this error is because the LVDT is not directly measuring targeting points on a sample, instead, the LVDT is measuring the distance between one point on the stop-end (where the tip rested on) and the holder. The wrong common sense hopes that this point on the stop-end and holder reliably following the movement of the sample points. But this study reveals that it is not always the case with the aid from the photogrammetry method. The messages of this paper are simple but alertly useful and, important: 1) the mounting system and the method of installation of the LVDTs have a significant impact on the actual displacement measurement in a mechanical properties test of timber materials. It should be carefully designed and validated before the actual test; 2) the displacement distribution is not uniform across the timber sample. This should be taken into account when selecting the mounting points of the LVDTs. Testing standards should consider this effect when recommending displacement transducers to be used in a timber-related test.

Published: September 2021

Background:
Systemic sclerosis (SSc) is a systemic autoimmune disease characterized
by microangiopathy, inflammation, fibrosis. Interstitial lung disease (ILD) is common among SSc
patients.

Objective:
This study aims to define the clinical, laboratory, and serologic characteristics of SSc patients
with ILD and to present the frequency of chest computed tomography features.

Methods:
Two hundred twenty-six SSc patients who applied to the Rheumatology Department between
January 2007 and August 2019 were retrospectively examined. A total of 100 SSc patients
with ILD (44.2%) were determined. Clinical, laboratory, and serological features of SSc patients
with and without ILD were compared.

Results :
Both groups had similar characteristics in terms of age and sex. The duration of disease
(p=0.001) and follow-up time (p=0.001) were longer in SSc patients with ILD. Multivariable logistic
regression analysis indicated that the duration of disease (OR: 1.06 (1.01-1.13), p=0.029), presence
of gastrointestinal system involvement (OR: 3.29 (1.28-8.46), p=0.013) and anti-SCL70-positivity
(OR: 6.04 (2.35-15.49), p <0.001) were associated with ILD. There was an inverse relationship
between Anti-CENP-B positivity and the presence of ILD (p=0.001). The assessment regarding
the chest computed tomography characteristics of interstitial pneumonia patterns were as follows:
82.5% non-specific interstitial pneumonia, 14.4% usual interstitial pneumonia, and 2.1%
desquamative interstitial pneumonia. The most frequent abnormal findings included ground-glass
opacification (88.7%), reticulation (64.9%), traction bronchiectasis (57.7%), septal thickening
(52.6%) and honeycombing (28.9%).

Conclusion:
We have shown a relationship between anti-SCL70, disease duration, gastrointestinal
system involvement, and ILD in SSc patients.

Published: September 2021

Introduction:
Tuberculosis (TB) is a serious infectious disease that affects human health
globally. The incidence of TB in prisons is usually much higher than the general population in different
countries. The aim of this study was to evaluate the incidence of TB among prisoners in Iran, estimating
the relative risk factors by performing a systematic and meta-analysis study on the related articles.

Methodology:
Our systematic and meta-analysis study was performed according to the PRISMA
guidelines. Two authors systematically searched Scopus, Iran doc, Cochrane, Pubmed, Medline, Embase,
Iran medex, Magiran, SID, Google Scholar, and EBSCO. The quality assessment of articles was
performed by using the Newcastle-Ottawa Scale. After article quality assessment, a fixed or random
model, as appropriate, was used to pool the results in a meta-analysis. Heterogeneity between the studies
was assessed using I-square and Q-test. Forest plots demonstrating the point and pooled estimates
were drawn.

Results:
Overall, data from 19562 prisoners indicated 63 cases of TB. The prevalence of TB in prisoners
was reported to range from 0.025% to 52% in eight studies. The highest prevalence of tuberculosis
was related to the study of Rasht, 517 in 100,000, and the lowest rate was related to the study of
Sought Khorasan, 25 in 100,000. The ES of the random effect model is 0.003 (95% CI, 0.001-0.005)
and p-value <0.0001. The Higgins’ I2 of all studies is 86.55%, and the p-value of the Cochrane Q statistics
is <0.001, indicating that there is heterogeneity. Based on the Egger regression plot (t=2.18, p =
0.08, CI 95%: -0.001, 0.005), no publication bias existed.

Conclusion:
According to the analysis findings, the frequency of tuberculosis among the prison in Iran
was low. The highest prevalence obtained in our systematic study was 517 in 100,000 in Rasht, which
was near the world statistics in the systematic review of world studies. Due to significant limitations in
this study, it is not possible to indicate the exact prevalence of TB in prisons in Iran and compare this
with the general population. However, more studies are needed to assess the related risk factors for
designing health intervention plans to decrease the incidence rate of TB among prisoners.
Cytokine Storm and Immunomodulation in COVID-19: A Review
Authors: Tripathi Vishwas , Arsh Amir Mohammad , Mishra Suhana , Mishra Amaresh 
Published: September 2021

Background:
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has taken
over the world, and more than 38 lakh deaths had been reported till now due to this infectious
disease. It has been declared a global pandemic by the world health organization. SARS-CoV-2
causes coronavirus disease of 2019 (COVID-19), and the major problem called “Cytokine storm”
is reported, which may lead to death among the COVID-19 patients. This study aimed to review
the Cytokine storm and its mechanism along with few immunomodulatory therapies for SARSCoV-
2 infection suppression effectively.

Methods:
The recently published works of literature were selected and reviewed based on the subject
of this study. The databases, including Pubmed, ScienceDirect, Scopus, and Google Scholar,
were searched extensively.

Results:
The review of the literature showed that an uncontrolled immune response causes excess
inflammation. Evidence from recent trials has demonstrated that cytokine storms can be an important
factor in the COVID-19 severity, leading to multiple organ failure and death.

Conclusion:
This study reviewed immunomodulatory therapies and strategies for SARS-CoV-2 infected
patients to suppress the immune response. Ultimately, the cytokine storm can prove to be a
boon and reduce the significant death tolls to SARS-CoV-2 infection.

Objetivo: establecer las diferencias entre tres tipos de productos de preparación para colonoscopia, en cuanto a efectividad y tolerabilidad.
Materiales y métodos: estudio de corte transversal, analítico, prospectivo, ciego para el evaluador de la escala de Boston. Se incluyeron pacientes adultos, mayores de 18 años con requerimiento de colonoscopia y diligenciamiento de la encuesta sobre el tipo de preparación realizada para la limpieza del colon.
Resultados: se evaluaron 3 grupos de productos (polietilenglicol, picosulfatos, sales de sulfato) en 907 pacientes, se aplicó la escala de Boston total y por segmentos, sin encontrar diferencias estadísticamente significativas entre ellos (Odds ratio [OR]: 1,10; intervalo de confianza [IC] 95 %: 0,6-1,8; p = 0,728). El 60 % de la población fueron mujeres y la edad promedio 52 años. Se observó el cumplimiento de la dieta en el 99 % de los participantes. La preparación dividida tuvo mejores resultados en la escala de Boston (OR: 5,06; IC 95 %: 3,2-8,01; p = 0,001). Los picosulfatos tuvieron mayor aceptabilidad (OR: 15,8; IC 95 %: 8,83-28,3; p = 0,001) y menores efectos secundarios como distensión abdominal (OR: 0,59; IC 95 %: 0,3-0,9; p = 0,033) y vómito (OR: 0,25; IC 95 %: 0,07-0,82; p = 0,015). Se observó mejor resultado cuando se realizó el examen antes de 6 horas de finalizada la preparación (OR: 6,38; IC 95 %: 3,84-10,6; p = 0,001).
Conclusiones: los productos evaluados no presentaron diferencias entre sí con respecto a su efectividad. Los picosulfatos tuvieron menores efectos secundarios y mejor aceptabilidad. Se obtuvo una mejor preparación del colon con preparación dividida y si el examen es hasta 6 horas de finalizada la preparación.
