Summary
This paper presents a data-driven methodology to predict calcium carbonate (CaCO3)-scale formation and design its inhibition program in petroleum wells. The proposed methodology integrates and adds to the existing principles of production surveillance, chemistry, machine learning (ML), and probability theory in a comprehensive decision workflow to achieve its purpose. The proposed model was applied on a large and representative field sample to verify its results.
The method starts by collecting data such as ionic composition, pH, sample-collection/inspection dates, and scale-formation event. Then, collected data are classified or grouped according to production conditions. Calculation of chemical-scale indices is then made using techniques such as water-saturation level, Langelier saturation index (LSI), Ryznar saturation index (RSI), and Puckorius scaling index (PSI). The ML part of the method starts by dividing the data into training and test sets (80 and 20%, respectively). Classification models such as support-vector machine (SVM), K-nearest neighbors (KNN), gradient boosting, gradient-boosting classifier, and decision-tree classifier are all applied on collected data. Prediction results are then classified into a confusion matrix to be used as inputs for the probabilistic inhibition-design model. Finally, a functional-network (FN) tool is used to predict the formation of scale.
The scale-inhibition program design uses a probabilistic model that quantifies the uncertainty associated with each ML method. The scale-prediction capability compared with actual inspection is presented into probability equations that are used in the cost model. The expected financial impact associated with applying any of the ML methods is obtained from defining costs for scale removal and scale inhibition. These costs are factored into the probability equations in a manner that presents incurred costs and saved or avoided expenses expected from field application of any given ML model. The forecasted cost model is built on a base-case method (i.e., current situation) to be used as a benchmark and foundation for the new scale-inhibition program.
As will be presented in the paper, the results of applying the preceding techniques resulted in a scale-prediction accuracy of 95% and realized threefold cost-savings figures compared with existing programs.
Contamination of Oil-Well Cement with Conventional and Microemulsion Spacers

Published: July 2020

Summary
The performance of oil-well cement is altered if contaminated by spacers. Very few studies in the literature are found on this topic, in particular for newly developed microemulsion spacers. Therefore, it is worth investigating the properties of cement contaminated with spacers. In this study, material characterization techniques including chemical shrinkage, ultrasonic pulse velocity (UPV), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and nitrogen adsorption (NAD) were used to study the hydration and microstructure of contaminated cement. Results showed that the studied microemulsion spacer was less compatible with the cement slurry than the conventional one. The microemulsion spacer has complex effects on cement hydration: it slightly enhances hydration for the low dosage but can retard hydration at the early ages and accelerate hydration in the later ages with the increase of dosage. The conventional spacer caused early acceleration of cement hydration but had no effect at later ages. The presence of spacers in the cement slurry decreases the compressive strength and creates a more complex microstructure than is found for the neat cement. All these effects with the studied microemulsion spacer are worse than with the conventional spacer. Therefore, the presence of a microemulsion spacer in a cement slurry may cause long-term durability issues compromising the downhole zonal isolation.

Abstract
Background: We investigated the correlations between surgery-related factors and the incidence of leakage after low anterior resection (LAR) for lower rectal cancer.Methods: A total of 630 patients underwent colorectal surgery between 2011 and 2014 in our department. Of these, 97 patients (15%) underwent LAR and were included in this retrospective study. Temporary ileostomy was performed in each patient.Results: Anastomotic leakage occurred in 21 patients (21.7%). Univariate analysis showed that operative duration (p=0.0051), transanal hand-sewn anastomosis (p=0.0141), and operation procedure (p=0.0191) were significantly associated with the occurrence of leakage. Multivariate analysis showed that underlying disease (p=0.0440), transanal hand-sewn anastomosis (p=0.0188) and drain type (p=0.0251) were significantly associated with the occurrence of leakage. Propensity-score analysis showed that closed drainage was associated with 6.3 times with anastomotic leakage than open drainage in patients, according to inverse probability of treatment-weighted analysis. Conclusions: Our results indicate that underlying disease, transanal hand-sewn anastomosis, and drain type may be risk factors for anastomotic leakage after LAR for lower rectal cancer. The notable finding was that the type of drainage was related to the occurrence of anastomotic leakage: closed drainage was correlated with the less volume of postoperative drain discharge than open drain.

Abstract
Background The examination of lymph nodes (LNs) plays an important role in the nodal staging of non-small cell lung cancer (NSCLC). For patients without LN metastasis, the main role of thorough LN examination is accurate staging, which weakens the effect of staging migration. To date, on the role of hilar and intrapulmonary (N1) station LNs has not been fully appreciated. In this study, we aimed to confirm the significance of N1 LNs in long-term survival for stage IA-IIA NSCLC patients and to find the minimum number of LN to examine.Methods The data of patients who underwent radical lobectomy and were confirmed as having nonmetastatic LNs from January 2008 to March 2018 were retrospectively screened. Pathology records were reviewed for the number of LNs examined. The Kaplan-Meier method and Cox regression model were used to identify survival and prognostic factors.Results The median number of resected N1 LNs was 8. The number of patients with 0-2 N1 LNs, 3-5 N1 LNs, 6-8 N1 LNs, 9-11 N1 LNs and more than 11 N1 LNs examined was 181, 425, 477, 414 and 531, respectively. Sex (P=0.004), age (P<0.001), tumor size (P=0.004), differentiation degree (P=0.001) and number of N1 LNs examined (P=0.008) were independent prognostic factors of overall survival. Gender (P=0.006), age (P=0.031), tumor size (P=0.001), differentiation degree (P=0.001), vascular invasion (P=0.034) and number of N1 LNs examined (P=0.007) were independent prognostic factors of disease-free survival. Conclusion Increasing the number of N1 LNs examination might improve the long-term survival of T1-2N0 NSCLC patients. These data indicate that the optimal practice involves examining at least 6 N1 nodes in surgical and pathological management but cannot prove this. This finding should be confirmed in a large, prospective randomized clinical study.

Published: July 2020

Abstract
Background: At present, patients with ocular myasthenia gravis (OMG) are typically treated with systemic drugs. We investigated the use of dexamethasone injected in the peribulbar region or extraocular muscle to treat patients with OMG. Methods: Patients with OMG were given dexamethasone via peribulbar injection or direct injection into the main paralyzed extraocular muscles, once a week, for 4-6 weeks. The severity of diplopia, blepharoptosis, eye position, and eye movement were evaluated before and after treatment. The duration of follow-up time was ≥6 months. Results: Among the 14 patients with OMG who received this treatment, mean age was 38.7 ± 29.7 years. After treatment, symptoms were relieved in 12 patients (85.7%), 1 patient (7.1%) had partial response to treatment, and 1 patient (7.1%) had no response. Two patients (14.2%) experienced symptom recurrence during the follow-up period.Conclusions: Dexamethasone peribulbar or extraocular muscle injection is effective in the treatment of patients with OMG and may replace systemic drug therapy.

Published: July 2020

Abstract
Background: Sacral tumors and tumor-like lesions are a rare group of lesions that can affect children and adults of all ages. Little is known about the epidemiological characteristics of them in China. Methods: 1385 patients with sacral tumors and tumor-like lesions, which had the clinical record at our bone tumor center from 2000 to November 2018 were analyzed. The metastatic cancers were not included in the present study. Results: 51.7% (716 cases) were malignant and 48.3 % (669 cases) were benign tumors or tumor-like lesions. Of malignant tumors, chordoma was the most common malignant tumor (316 cases, 22.8% of all tumors), followed by chondrosarcoma, myeloma and other histologic types. The most common histological type of benign tumors was giant cell tumor accounting for 14.8% (205 cases) of all tumors, followed by neurofibroma, schwannoma and other types. The most common age group affected by malignant bone tumors was the 51- to 60-year-old group, followed by the 41- to 50-year-old group. The most commonly affected age group for benign tumors and tumor-like lesions was the 31- to 50-year-old group, followed by the 21- to 30-year old group. Furthermore, the following histologic types had the gender predilection. Chordoma, chondrosarcoma, myeloma and osteosarcoma affected more frequently males than females. Malignant peripheral nerve sheath tumor, lymphoma, giant cell tumor, neurofibroma, tuberculosis, teratoma and epidermoid cyst more frequently affected females than males. Conclusions: The large cohort of sacral tumors and tumor-like lesions in our database may reveal their epidemiologic characteristics in China and epidemiological feature of sacral tumors and tumor-like lesions is fairly distinct from the mobile spine and extremities.

Abstract
Objectives: Ukrainians numbering approximately 1.2 million are the largest migrant group in Poland. Data on vaccination coverage among migrants are not collected in EU, including Poland. Therefore, this qualitative study aimed to identify vaccination practices in this group, to explore facilitators/barriers to vaccination and related access to Polish healthcare services.Methods: In September 2019, a qualitative study of Ukrainian migrants (UMs) living in Szczecin, Poland, and recruited through a snowball sampling method, was conducted. Using a semi-structured topic guide, four focus groups were held with 22 UMs aged 18-45. Participants were asked about attitudes towards vaccination in general with comparison between services in Poland and Ukraine. Following transcription and translation, a thematic analysis was conducted.Results: Respondents were distrustful of Ukrainian vaccination policy, medical personnel and individual vaccines, however, they often returned to Ukraine for dental and gynaecological appoint-ments. While critical with regards to registering with Polish GPs practices, UMs were confident in health professionals, as well as vaccine delivery. Vaccines were perceived as safer and of better quality than in Ukraine. Difficulties in translating vaccination records were rarely reported, verbal communi-cation was not problematic due to language similarities. All UM parents reported vaccinating their children according to the Polish schedule. However, a significant number of adult UMs have not completed mandatory vaccinations, although they may have obtained false immunization certificates; according to UMs those can be obtained by bribing. Participants reported lower acceptance of the influenza vaccine, mainly due to perceptions around its importance; none had been vaccinated against influenza. None of UMs had heard of the HPV vaccine. UMs experienced challenges in accessing credible online vaccination information in Ukrainian, no official local health authority vaccination material existed either, except for information about measles.Conclusions: This study pinpointed positive UM attitudes and practices regarding child vaccination in the Polish healthcare system and identified issues for improvement, such as adult vaccination. Health communication should be more tailored within UMs information delivery systems to enable migrants to make informed choices about vaccination. Further research is needed to better assess factors affecting vaccine uptake identified in this study.

Abstract
Background: Methanol is widely used in industry; however, methanol poisoning is not common. In this regard, a number of outbreaks have been recently reported due to inappropriate processing of alcoholic beverages. Shiraz, a city located in the southern part of Iran, faced one of such outbreaks in 2020 during COVID-19 pandemic. There is no sufficient literature on the electrocardiographic findings in methanol toxicity. This study aimed to address this gap in the literature.Method: A total of 356 cases with methanol toxicity referred to Shiraz University of Medical Science Tertiary Hospitals (Faghihi and Namazi) in March and April, 2020. The clinical findings of blindness and impaired level of consciousness, lab data such as arterial blood gas, electrolytes, and creatinine, and the most common findings from ECGs were collected. Results: The most common ECG findings were J point elevation (68.8%), presence of U wave (59.2%), QTc prolongation (53.2% in males and 28.6% in females), and fragmented QRS (33.7%). An outstanding finding in this study was the presence of myocardial infarction in 5.3% of the cases. This finding, to the best of our knowledge, has only been reported in a few case reports. Brugada pattern (8.1%) and Osborn wave (3.7%) were the other interesting findings.In multivariate analysis, when confounding factors were adjusted, myocardial infarction, atrioventricular conduction disturbances, sinus tachycardia, and the prolonged QTC>500 msecond were four independent factors correlated with methanol toxicity severity measured with arterial blood PH on arterial blood gas measurements, with odds ratios of 12.82, 4.46, 2.32 and 3.15 (P<0.05 for all) , respectively.Conclusion: Electrocardiographic variations during methanol intoxication are remarkable and well-correlated with poisoning severity. Myocardial infarction was an egregious and yet a common concerning finding in this sample, which need to be ruled out in methanol toxicity.

Abstract
IntroductionHealthcare workers (HCW) are presumed to be at increased risk of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection due to occupational exposure to infected patients. We aim to determine the prevalence of anti-SARS-CoV-2 antibodies among asymptomatic HCW.MethodsWe prospectively recruited HCW from the National Public Health Laboratory and two COVID-19 designated public hospitals in Klang Valley, Malaysia between April 13th and May 12th, 2020. Quota sampling was applied to ensure adequate representation of the HCW involved in provision of care for patients directly and indirectly. All participants had worked in the respective healthcare facility for at least 30 days prior study enrollment. HCW who were previously confirmed with COVID-19 infection or listed as “patient under investigation” were excluded. A self-administered questionnaire was used to capture sociodemographic information, history of contact with COVID-19 cases within the past month, clinical signs and symptoms and adherence to universal precautions. Blood samples were taken to test for anti-SARS-CoV-2 antibodies by surrogate virus neutralization test.ResultsA total of 400 HCW were recruited, comprising 154 (38.5%) nurses, 103 (25.8%) medical doctors, 47 (11.8%) laboratory technologists and others (23.9%). The mean age was 35±7.8 years, with females predominant (74%). A majority (68.9%) reported direct contact with COVID-19 patients, body fluids of COVID-19 patients and/or contaminated objects and surfaces in the past month within their respective workplaces. Nearly all claimed to adhere to personal protection equipment (PPE) guidelines (97%-100% adherence) and hand hygiene practice (91%-96% adherence). None (95% CI: 0, 0.0095) of the participants had anti-SARS-CoV-2 antibodies detected, despite 135 (33.8%) reporting respiratory symptoms one month prior to study recruitment. One hundred and fifteen (29%) participants claimed to have contact with known COVID-19 persons outside of the workplace.ConclusionOur finding of zero seroprevalence among asymptomatic HCW suggests a low risk of asymptomatic COVID-19 infection in our healthcare setting; which is at expected levels for a country with an incidence of 26 per 100,000. The adequacy of PPE equipment and strict adherence to infection prevention and control measures offers considerable protection during contact with COVID-19 cases and should be ensured to prevent future nosocomial transmission.
Scanning electron microscopic observations of antennal sensilla, and the cloning and expression of the BiOr816 gene of Bombus ignites from China
Authors: Wang Dandan , Wang Xing , Li Xiao-Hong 
Published: July 2020

Abstract
Odorant receptors play a crucial role in the special recognition of scent molecules in the bumblebee olfactory system. In this study, four types of sensilla were observed on the antennae of worker bees through a scanning electron microscope (SEM), which were mainly distributed with sensillum placodeum sensillum coeloconicum, sensillum trichodeum and sensillum cavity. The odorant receptor 816 gene (BiOr816) from Bombus ignites was cloned, and its expression profiles were examined during different developmental stages and tissues. The phylogenetic tree was divided into four branches: Messor orientalis; Apis cerana ceran, Apis mellifera and Apis dorsat; Bombus lantschouensis, Bombus terrestris and Bombus ignites; and Drosophila melanogaster. The cDNA sequence of BiOr816 was found to be highly similar to BtOr22c (98.2%), which encoded a membrane-coupled protein of 385 amino acids. The BiOr816 protein belongs to the 7-transmembrane_6 receptor superfamily. Accordingly, the results of the quantitative real-time PCR (qRT-PCR) indicated that BiOr816 was expressed at high levels in worker bee antennae compared to its head, thorax, abdomen, legs and wings. This demonstrated that the antenna played a vital role in the process of olfactory recognition in bumblebees and served as its most important olfactory organ, which was consistent with the corresponding electron microscope photos showing many sensilla on the antennae.
