Authors: Dong Jingjing , Geng Yan , Wang Bowen , Zhang Shu
Published: October 2020

BackgroundAt the beginning of 2020, COVID-19 broke out in Wuhan, China. Medical staff from all over the country quickly supported Wuhan and put into combat. In May 2020, the epidemic has been effectively controlled, and medical staff withdrew from Wuhan and entered into recuperation. MethodsDuring the recuperation in March and June, 2020, 441 medical staff were participated to investigate the psychological symptoms on SCL-90. Student's t-test and one-way analysis of variance were chosen to analyze the data. ResultsOf the 441 participants, the positive ratio (i ≥ 2) of the ten dimensions and the average score of SCL-90 was from 3.17% to 13.61%. Compared respectively with the medical staff in front-line and the Chinese norms, the scores obviously decreased during the recuperation. Gender, occupation, professional ranks and titles, working position in Wuhan and the patient’s condition affected the scores of SCL-90, age and educational attainment had little effect. ConclusionsThese results showed that the recuperation had the positive impact on the psychological status of the medical staff after fighting against COVID-19, which is worthy of further promotion. Our findings also showed that a small number of medical staff still had the risk on the mental problem, which need continuous attention and intervention.

Published: October 2020

Background Urinary tract infections (UTI) are one of the most common conditions in females. Current information on presentation, management and natural course of the infection is based on paper diaries filled out by patients and subsequently posted. The aim of the study was to explore the feasibility of a smartphone app to assess the natural course and management of urinary tract infections.Methods A smartphone app was developed to collect data from study participants presenting in general practice with symptoms of a UTI. After initial demographic and treatment information, symptom severity was recorded by the patient upon a reminder on their smartphone which occurred twice daily for a period of 7 days or until symptom resolution. Results A total of 181 women aged 18-76 downloaded the smartphone app. Duration of symptoms was obtained from the results of 178 participants. All patients had a urine sample submitted, most patients were prescribed an antibiotic (90%) and 39% had a positive culture. Moderately bad or worse symptoms lasted a mean of 3.8 days (median 4) and 70% of patients indicated that they were cured on day 4 after consultation. This compares with other research assessing symptom duration and management of UTIs where data is collected by paper diaries. Patients were very positive about the usability of the smartphone app and often found the reminders supportive. Based on the feedback and the analysis of the data, some suggestions for improvement were made. Conclusions Smartphone diaries for symptom scores over the course of infections are an efficient and acceptable means to collect data in research.

Published: October 2020

Background: Caesarean sections often have no urgent indication and are electively planned. Research showed that elective caesarean section should not be performed until 39+(0-6) week of gestation to ensure best neonatal and maternal health if there are no contraindications. This was recommended by various guidelines published in the last two decades. With this systematic review we are looking for implementation strategies trying to implement these recommendations into clinical practice. Methods: We performed a systematic literature search in MEDLINE, EMBASE, CENTRAL and CINAHL in November 2019. We included studies that assessed implementation strategies aiming to postpone elective caesarean section to ≥39+(0-6) week of gestation. There were no restrictions regarding the type of implementation strategy or reasons for elective caesarean section. Our primary outcome was the rate of elective caesarean sections before 39+(0-6) week of gestation. We did a narrative analysis of the results.Results: We included 9 studies, of which were 2 interrupted time series and 7 before-after studies, covering 205.954 elective caesarean births. All studies included various types of implementation strategies. All implementation strategies showed success in decreasing the rate of elective caesarean sections performed <39+(0-6) week of gestation. Risk difference differed from -7 (95% CI -8; -7) to -45 (95% CI -51; -31). 3 studies reported rate of neonatal intensive care unit admission and showed little reduction.Conclusion: This systematic review shows that all presented implementation strategies to reduce elective caesarean section before 39+(0-6) weeks of gestation are effective. Reduction rates differ widely and it remains unclear which strategy is most successful. Strategies used locally in one hospital seem a little more effective. For planning an implementation strategy to reduce elective caesarean section before 39+(0-6) weeks of gestation it is necessary to consider specific barriers and facilitators and take all obstetric personal into account.Systematic review registration: Registered in PROSPERO (CRD42017078231)

Published: October 2020

Background: The objective of this study was to assess the impact of the recurrent laryngeal nerve injury (RLNI) after esophagectomy on prognosis.Methods: Retrospectively collected data from 297 patients with esophageal squamous cell carcinoma who underwent McKeown esophagectomy at our department from April 2014 to May 2018, were analyzed.Results: RLNI occurred in 31.9% of the patients. Left-side RLNI occurred 2.8 times more often than right-side RLNI. Among the cases in which assessment of the vocal cords was continued, 8.4% involved permanent injury. There were no significant differences among clinicopathological data between patients with RLNI and without. Compared with patients without RLNI,patients with RNLI have longer operation time,more number of bronchoscopy suctions, longer postoperation hospital stay, and higher incidence of postoperative complications. T stage, N stage, RLN LN metastasis were independent risk factors for the prognosis, but RLNI is not independent risk factors for long-term survival. Conclusion: RLNI is a serious complication that will affect the short-term prognosis of patients and reduce the quality of life of patients. It should be avoided as much as possible during surgery, but it may not have negative impact on the long-term survival.

Published: October 2020

The purpose of the study is to extend the use of nuclear magnetic resonance relaxometry and dielectric spectrometry methods. This is realized through a complex interpretation of the data by the above methods to timely provide additional petrophysical information about the drill cuttings pore space properties and structure. The relevance of the study is that the data on the drill cuttings obtained by the NMR method can be used as prior information in the logging data interpretation before a detailed petrophysical study of the core sample or in case of the core absence in the sampling interval. The objects of study are the drill cuttings samples from the fields of the West Siberian oil-and-gas province. The samples are saturated with different fluids, and their reservoir properties are determined by the nuclear magnetic resonance and dielectric spectrometry methods. As part of the experimental research, nuclear magnetic resonance investigations of the core samples of different discretization degrees have been carried out to determine the reservoir properties of the samples depending on the degree of their particle size reduction. It has been shown that the obtained results do not depend on the particle size of the measured sample and are consistent with the results of the standard petrophysical studies. The relationship between the porosity and the saturating fluid type has been established. Based on the data obtained by the dielectric spectroscopy method, the study has determined the value of the complex dielectric constant that shows how the degree of saturation changes depending on the fluid, and what happens in the pore space. The complex interpretation of the results obtained by the two methods provides additional information on the drill cuttings reservoir properties that can be used as a priori information on the formation properties.

Upgrade of the Taskila WWTP with an MBR line: the first treatment results, performance assessment and lessons learnt
Authors: Haimi H. , Risteelä S. , Di Pofi M. , Lahtinen J.
Published: October 2020

In this paper, we present the first results of a large-scale membrane bioreactor application implemented for increasing the wastewater treatment plant capacity. The Taskila plant in Finland was upgraded in 2018 and is now operated as a hybrid system with parallel membrane bioreactor and conventional biological lines. The results showed that membrane filtration improved the plant performance significantly in terms of the solids and pathogens removal. Nitrogen removal has been stable with the current operating set-points and notably better than before the plant expansion. The analysis using key performance indicators showed that there were no significant differences in operational expenditures between the membrane and conventional lines. The membrane filtration results highlight the importance of maintaining the good sludge filterability properties that enable higher operational fluxes and reduced energy consumption. The low membrane aeration flow-rate mode, the standard operating mode with good sludge filterability, enabled reduction of total aeration energy consumption by 34% for the membrane bioreactor, including both activated sludge and membrane aeration. Fine-tuning of the hybrid plant is still going on and, therefore, improved overall results are expected in the forthcoming years.

Published: October 2020

In this study, activated carbon (AC) was prepared from agro-waste betel nut husks (BNH) through the chemical activation method. Different characterization techniques described the physicochemical nature of betel nut husks activated carbon (BNH-AC) through Fourier transform infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET), scanning electron microscopy (SEM), and pH point of zero charge. Later, the produced AC was used for methylene blue (MB) adsorption via numerous batch experimental parameters: initial concentrations of MB dye (25–250 mg/L), contact time (0.5–24 hours) and initial pH (2–12). Dye adsorption isotherms were also assessed at three temperatures where the maximum adsorption capacity (381.6 mg/g) was found at 30 °C. The adsorption equilibrium data were best suited to the non-linear form of the Freundlich isotherm model. Additionally, non-linear pseudo-second-order kinetic model was better fitted with the experimental value as well. Steady motion of solute particles from the boundary layer to the BNH-AC's surface was the possible reaction dynamics concerning MB adsorption. Thermodynamic study revealed that the adsorption process was spontaneous and exothermic in nature. Saline water emerged as an efficient eluent for the desorption of adsorbed dye on AC. Therefore, the BNH-AC is a very promising and cost-effective adsorbent for MB dye treatment and has high adsorption capacity.

Authors: Güy Nuray , Atacan Keziban , Boutra Belgassim , Özacar Mahmut
Published: October 2020

The formation of heterojunction structures of semiconductors is one of the most important techniques to increase the photocatalytic efficiency of a photocatalyst. In this paper, Ag/Ag3VO4/TiO2 as a visible light response photocatalyst was prepared easily by a three step process including hydrothermal, precipitation and photoreduction. The Ag/Ag3VO4/TiO2 nanocomposites demonstrated clearly increased visible light absorption and photocatalytic efficiency in degradation of Rhodamine B. The degradation yield of Rhodamine B was detected 97.3% in 45 min under visible light. Compared with Ag3VO4, TiO2 and Ag3VO4/TiO2, Ag/Ag3VO4/TiO2 exhibited the highest efficiency owing to synergetic effect between Ag3VO4 and TiO2 and surface plasmon resonance effect of Ag nanoparticles. So, the Ag/Ag3VO4/TiO2 can be effectively used as an active photocatalyst under visible light and it depicts an ideal potential in elimination organic pollutants.

Investigation of Low Dose Cabazitaxel Potential as Microtubule Stabilizer in Experimental Model of Alzheimer's Disease: Restoring Neuronal Cytoskeleton
Authors: Duggal Pallavi , Jadaun Kuldeep S. , Siqqiqui Ehraz M. , Mehan Sidharth
Published: October 2020

Background:

Neuronal Microtubule (MT) tau protein, providing cytoskeleton to neuronal
cells, plays a vital role, including maintenance of cell shape, intracellular transport, and cell division.
Tau hyperphosphorylation mediated MT destabilization results in axonopathy, additionally neurotransmitter
deficit and ultimately causing Alzheimer's disease. Pre-clinically, streptozotocin (3mg/kg, 10μl/
unilateral, ICV) stereotaxically mimics the behavioral and neurochemical alterations similar to Alzheimer's
tau pathology resulting in MT assembly defects further lead to neuropathological cascades.

Objective:

Clinically approved medications such as Donepezil (DNP), rivastigmine, and Memantine
(MEM) are responsible for symptomatic care only, but there is no specific pharmacological intervention
that directly interacts with the neuronal microtubule destabilization.

Methods:

The current study focused on the involvement of anti-cancer agent microtubule stabilizer cabazitaxel
at a low dose (0.5 and 2 mg/kg) alone and in combination with standard drugs DNP (5 mg/kg),
MEM (10 mg/kg) and microtubule stabilizer Epothilone D (EpoD) (3 mg/kg) in the prevention of intracerebroventricular
streptozotocin (ICV-STZ) intoxicated microtubule-associated tau protein hyperphosphorylation.

Results:

Chronic treatment of CBZ at a low dose alone and in combination with standard drugs showing
no side effect and significantly improve the cognitive impairment, neurochemical alterations along with
reducing the level of hyperphosphorylated tau by preventing the breakdown of the neuronal cytoskeleton,
respectively.

Conclusion:

The above findings suggested that CBZ at low dose show neuroprotective effects against
ICV-STZ induced microtubule-associated tau protein hyperphosphorylation in rats and may be an effective
agent for the preventive treatment of AD.
Atherogenic Index of Plasma in Women with Rheumatoid Arthritis and Systemic Lupus Erythematosus: A 10-Year Potential Predictor of Cardiovascular Disease
Authors: Hammam Nevin , Abdel-Wahab Noha , Gheita Tamer A
Published: October 2020

Background:

Women with rheumatoid arthritis (RA) and systemic lupus erythematosus
(SLE) are at high risk of cardiovascular diseases (CVD). The atherogenic index of plasma (AIP) is
a new marker for the assessment of CVD.

Objective:

This study aimed to determine the predictive value of AIP with long-term CVD risk
among women with RA and SLE.

Methods:

This is a cross-sectional study of 99 RA and 59 SLE women. Demographic, clinical, and
biochemical data were obtained, and disease activities were calculated. For each patient, the longterm
risk of CVD was calculated using the Framingham risk score (FRS); AIP was derived according
to the logarithmic (triglycerides/high-density lipoproteins cholesterol).

Results:

The mean age of the RA and SLE patients was 47.97 ± 8.78 and 36.75 ± 9.09 years, respectively.
The median (interquartile range) of AIP values in RA and SLE patients were 0.34
(-0.15, 1.02) and 0.33 (-0.53, 0.96), respectively, while FRS values of RA patients and SLE patients
were 6.38 ± 5.58 and 4.86 ± 4.5, respectively (p >0.05). There was a moderate correlation between
AIP and FRS in RA and SLE patients (r=0.42, p=0.002 and r=0.33, p=0.007, respectively).
According to the multivariate regression analyses, we found that AIP value is an independent factor
for FRS in RA (β: 4.13, 95% confidence interval; 1.71, 6.18; p=0.008) and in SLE patients (β:
6.19, 95% confidence interval; 2.58, 9.81; p<0.001).

Conclusions:

: We reported that AIP can be used as an independent indicator for long-term CVD
risk in RA and SLE patients.

Authors: Mumin Nazimah Ab , Rahmat Kartini , Hamid Marlina Tanty Ramli , Ng Wei Lin , Chan Wai Yee , Cheah Xin Ying , See Mee Hoong , Yip Cheng Har
Published: October 2020

Background:

Primary breast angiosarcoma is a rare malignancy with non-specific clinical
and radiological findings.

Case Report:

A 30-year-old lady presented with left breast pain and lumpiness for over one year.
She has had several breast ultrasounds (US) and was treated for acute mastitis and abscess. Subsequently,
in view of the rapid growth of the lump and worsening pain, she was re-investigated with
US, elastography, digital breast tomosynthesis (DBT) and MRI. MRI raised the suspicion of angiosarcoma.
The diagnosis was confirmed after biopsy and she underwent mastectomy.

Discussion:

Literature review on imaging findings of breast angiosarcoma, especially on MRI, is
discussed. MRI features showed heterogeneous low signal intensity on T1 and high signal intensity
on T2. Dynamic contrast enhancement (DCE) features included either early enhancement with or
without washout in the delayed phase, and some reported central areas of non-enhancement.

Conclusion:

This case report emphasises on the importance of MRI in clinching the diagnosis of
breast angiosarcoma, and hence, should be offered sooner to prevent diagnostic delay.

Examinamos si las rentas de recursos naturales son probablemente mejor administradas bajo instituciones fuertes (o falta de estas), y de serlo así si eso contribuye al desarrollo económico de países con abundantes recursos naturales. Estimamos un modelo usando evidencia de booms (1970-2012) de recursos, rentas de recursos, capital natural, indicadores socio-económicos y de instituciones.

Demostramos por un lado 1) países con capital natural y riqueza del subsuelo están asociados a una sana democracia lo que mitiga la maldición de los recursos naturales; por el otro lado 2) altos niveles de renta están negativamente asociados a la baja calidad de instituciones lo que profundiza la maldición.

El crecimiento económico a largo plazo está asociado a el capital natural pero tal crecimiento esta negativamente asociado en países que registran altos percepciones de rentas. Recomendamos transparencia en: la distribución de rentas, las ventas de petróleo, distribución de licencias y la recaudación de rentas. Una limitación es la falta de información: leyes (sector energético) que produzcan el crecimiento. Explicamos el impacto de largo plazo de el cambio democrático sobre la gestión de la rentas.

BACKGROUND

The adverse effects of COVID-19 pandemic on the mental health of high-risk group patients for morbidity and mortality and its impact on public health in the long term have not been clearly determined.

OBJECTIVE

To determine the level of COVID-19 related transmission fear and anxiety in healthcare workers and patients with primary immunodeficiency disorder (PID), severe asthma, and the ones with other comorbidities.

METHODS

The healthcare workers and patients with PID, severe asthma (all patients receiving biological agent treatment), malignancy, cardiovascular disease, hypertension (90% of patients receiving ACEI or ARB therapy), diabetes mellitus (42 % of patients receiving DPP-4 inhibitor therapy) were included in the study. A total of 560 participants, 80 individuals in each group, were provided. The hospital anxiety and depression scale ( HADS ) and Fear of illness and virus evaluation (FIVE ) scales were applied to the groups with face to face interview methods.

RESULTS

The mean age was 49.30 years and 306 (55 %) were female. The FIVE Scale and HADS-A scale scores of health care workers were significantly higher than other groups' scores (p = 0.001 and 0.006). The second-highest scores belonged to patients with PID. There was no significant difference between the groups for the HADS-D score (p=0.07). The lowest score in all scales was observed in patients with hypertension.

CONCLUSIONS

This study demonstrated that in the pandemic process, patients with primary immunodeficiency, asthma patients, and other comorbid patients, especially healthcare workers, should be referred to the centers for the detection and treatment of mental health conditions.

Published: October 2020

The extracted seeds of African breadfruit are identified to be extremely healthy whenever it is correctly processed. Therefore, the aim of the present study was to evaluate the effects of processing methods on the nutritional quality of African breadfruit seed. A qualitative phytochemical analysis including: Alkaloid, Flavonoid, Saponin, Tannin, Anthraquinone, Terpenoids, Steroid, and Cardiac Glycosides for the different fraction of African breadfruit seed was performed using a standard method. The result revealed the presence and greater amount of phytochemical for the raw fraction; seven in eight, six in eight for steamed fraction, and four in eight for boiled and roasted respectively. Anti-nutrient, Proximate, and Mineral Content were also conducted using standard methods. The amino acid composition was determined using High-Performance Liquid Chromatography (HPLC). The results of the present study revealed that anti-nutrients including Phytate, Tannins, and Oxalate were significantly p<0.05 reduced in the boiled fraction 5.47±0.15, 3.42±0.02 and 6.89±0.05, and highest in the raw fraction 7.77±0.01, 5.09±0.03 and 9.34±0.14. The proximate composition including; percentage crude fat, Ash, Carbohydrate, Fatty acid, and Energy value were significantly lower p<0.05 in the boiled fraction relative to the other fractions. Mineral contents; calcium, magnesium, sodium, potassium, and phosphorus were also significantly p<0.05 elevated in the boiled fraction relative to the raw, steamed, and roasted fraction. The amino acid composition was highest in the roasted and boiled fraction 57.350 and 56.978, and lowest in the steamed and raw fraction 35.754 and 28.748 respectively. Therefore, boiling (cooking) is encouraged for the preparation of African breadfruit seed.
How Far Can Tourism Go? Residents' Attitudes toward Tourism Development in Yogyakarta City, Indonesia
Authors: Yusuf Mohamad
Published: October 2020

In the last 10 years, tourism has been rapidly growing in Yogyakarta. Studies show that tourism development in Yogyakarta has led to irritated feelings among local residents. This study aims to measure residents' attitudes toward tourism development in Yogyakarta by using validated measurement properties with a scale that measures residents' attitudes toward sustainable tourism development (SUS-TAS). The instrument was distributed to 1,687 local residents living in three main tourist destinations in Yogyakarta. Confirmatory factor analysis was conducted to measure the validity and internal reliability of each variable. Descriptive quantitative analysis was also conducted to investigate the level of agreement among residents to each variable. Findings support the seven dimensions in the SUS-TAS scale. Perceived social cost and community participation are the variables with the lowest level of agreement among the variables. Results also confirm underlying tourism development problems in Yogyakarta.

Urban poverty coupled with housing shortages have contributed to the proliferation of informal settlements and slums. This is one of the complex problems arising out of urbanization and which is piling pressure on urban authorities to use unorthodox methods (such as forced evictions) to ameliorate the situation. This paper revisits the use of forced migration in Badia East Community of Lagos city. Using the human security concept as a framework for analysis, the paper chronicles how urban forced migration is used as a tool to relocate the vulnerable urban poor by urban authorities in their bid to achieve sustainable development. Critical insight into the nature of these migrations was achieved by gathering data using the mixed approach. Finding from the study revealed rampant human abuse through the use of force during the eviction process. The paper concludes by recommending that the government should use best practices, (such as adequate government-assistance) during relocations and rehousing option explored.

Published: October 2020

Land prices, especially in an urban area, are dynamically changing.  To be able to do an evaluation, the right models must have the ability to understand land price characteristics that also dynamically changing. Every land price must attach to a location (spatial based). One of the locations (spatial based) models is Geographically Weighted Regression (GWR). This model can provide a local model based on the concept of attachment between observation and regression points. The main component is the determination of Optimum Bandwidth, which will determine the accuracy of the final GWR model. In the bandwidth process, it is necessary to do trial and error to get the Optimum Bandwidth value. Cross-Validation method commonly used to determine optimum bandwidth on observation point, but this study aims to minimize the process of trial and error in determining optimal bandwidth outside the observation point by using kriging interpolation. The Kriging method can substantially provide better bandwidth usage without having to do a trial process with too many errors.

The Indonesian government has spent lots of budgets and built more infrastructures to escalate the intensive rice farming in the tidal swamps since 1970s. However, the success story is very limited.  This study aims to describe some obstacles in the practice of rice intensification, and also to explain some factors leading to their failure.  In explaining this context, we refer them to our-own-experiences in tidal lowlands development project from 2008 to 2009, literatures study, and then it is deepened by doing collectives case study –that is consisting of three studies in the type of-B, C, and D overflows.  The local farmers used to reject the intensive rice farming practices.  The use of local paddy varieties is a prefer strategy option. It is closely related to minimize the farming cost and also as a strategy so that they have more time to manage another farm activities.  Rationally the farmers prefer growing a variety of perrenial crop species that suits their personal needs and strategies. In conclusion, this study showed that agro-ecological based farm could be the most adaptive way in optimizing the indigenous rice farming.

Published: October 2020

Aim:
 To evaluate the cost–effectiveness of polatuzumab vedotin (pola) + bendamustine + rituximab (BR) in relapsed/refractory diffuse large B-cell lymphoma based on the GO29365 trial from a US payer’s perspective.
Materials & methods:
 A partitioned survival model used progression-free survival and overall survival data from the GO29365 trial. The base case analysis assumed overall survival was informed by progression-free survival; a mixture cure model estimated proportion of long-term survivors.
Results:
In the base case, pola + BR was cost-effective versus BR at US$35,864 per quality-adjusted life year gained. Probabilistic and one-way sensitivity analyses showed that the findings were robust.
Conclusion:
Pola + BR is cost-effective versus BR for the treatment of transplant-ineligible relapsed/refractory diffuse large B-cell lymphoma in the US.

Sustainable Higher Education as a Challenge for Latvia: Impact of the Constitutional Court of the Republic of Latvia
Authors: Rodiņa Anita
Published: October 2020

In view of the current relevance of the concept of sustainability, the article examines the application of this principle within the system of higher education in three essential areas, analysing the existing situation and outlining the necessary improvements in the context of sustainability. The article also reveals the impact of the rulings delivered by the Constitutional Court of the Republic of Latvia on the sustainable development of institutions of higher education, highlighting the rulings, which directly deal with issues important for institutions of higher education, inter alia, in the context of the development of the rule-of-law state. The author also expresses her opinions on the need for a dialogue between the legislator and the Constitutional Court on these matters, as well as urges to seek solutions to several essential issues regulating the life of institutions of higher education – both with respect to regulation on the employment legal relationship and the criteria set for the Latvian Science Council’s expert in the legal science.
