Published: September 2020

AbstractReliable hazard analysis is crucial in the flood risk management of river basins. For the floodplains of large, developed rivers, flood hazard analysis often needs to account for the complex hydrology of multiple tributaries and the potential failure of dikes. Estimating this hazard using deterministic methods ignores two major aspects of large-scale risk analysis: the spatial–temporal variability of extreme events caused by tributaries, and the uncertainty of dike breach development. Innovative stochastic methods are here developed to account for these uncertainties and are applied to the Po River in Italy. The effects of using these stochastic methods are compared against deterministic equivalents, and the methods are combined to demonstrate applications for an overall stochastic hazard analysis. The results show these uncertainties can impact extreme event water levels by more than 2 m at certain channel locations, and also affect inundation and breaching patterns. The combined hazard analysis allows for probability distributions of flood hazard and dike failure to be developed, which can be used to assess future flood risk management measures.

Published: September 2020

AbstractHeating, ventilation and air conditioning (HVAC) systems are the most energy-consuming building implements for the improvement of indoor environmental quality (IEQ). We have developed the optimal control strategies for HVAC system to respectively achieve the optimal selections of ventilation rate and supplied air temperature with consideration of energy conservation, through the fast prediction methods by using low-dimensional linear ventilation model (LLVM) based artificial neural network (ANN) and low-dimensional linear temperature model (LLTM) based contribution ratio of indoor climate (CRI(T)). To be continued for integrated control of multi-parameters, we further developed the fast prediction model for indoor humidity by using low-dimensional linear humidity model (LLHM) and contribution ratio of indoor humidity (CRI(H)), and thermal sensation index (TS) for assessment. CFD was used to construct the prediction database for CO2, temperature and humidity. Low-dimensional linear models (LLM), including LLVM, LLTM and LLHM, were adopted to expand database for the sake of data storage reduction. Then, coupling with ANN, CRI(T) and CRI(H), the distributions of indoor CO2 concentration, temperature, and humidity were rapidly predicted on the basis of LLVM-based ANN, LLTM-based CRI(T) and LLHM-based CRI(H), respectively. Finally, according to the self-defined indices (i.e., EV, ET, EH), the optimal balancing between IEQ (indicated by CO2 concentration, PMV and TS) and energy consumption (indicated by ventilation rate, supplied air temperature and humidity) were synthetically evaluated. The total HVAC energy consumption could be reduced by 35% on the strength of current control strategies. This work can further contribute to development of the intelligent online control for HVAC systems.
Tribocorrosion properties of AISI 1045 and AISI 2205 steels in seawater: Synergistic interactions of wear and corrosion

Published: September 2020

AbstractTribocorrosion denotes an irreversible material degradation for several metallic components used in corrosive environments, and it arises from the interplay between chemical, mechanical, and electrochemical processes. In this study, some investigation has been performed to compare the tribocorrosion behavior of AISI 1045 steel and AISI 2205 duplex stainless steel sliding against an alumina pin in seawater. The lowering in the open circuit potential (OCP) of AISI 2205 during the tribocorrosion demonstrates that its protective passive film was damaged by wear and resulted in a wear-accelerated corrosion in the wear track. However, sliding was found to accelerate the corrosion of the unworn areas for AISI 1045, leading to an anodic shift of the OCP. Moreover, the total material loss increased with an increase in the applied potential for both materials. It was revealed that AISI 1045 was more sensitive to corrosion under sliding than AISI 2205. Therefore, pure corrosion loss and corrosion-induced wear constituted the primary reasons for the degradation of AISI 1045 at applied anodic potentials.

Abstract

Introduction
An increased risk of sexual health problems is seen among patients with chronic illnesses. The background is likely to be multifactorial, but it remains poorly understood.

Aim
To investigate the sexual health and functioning of patients with rheumatoid arthritis (RA) and to examine gender differences, general population comparisons, and possible somatic, psychological, and disease-specific determinants.

Methods
A cross-sectional study using a digital questionnaire distributed among 380 patients diagnosed with RA in a Danish university hospital outpatient setting.

Main Outcome Measure
A range of patient-reported outcomes were obtained, including scores from the validated rating scale Changes in Sexual Functioning Questionnaire. Furthermore, individual medical record information was collected.

Results
A total of 329 patients (250 women and 79 men) were included (age range: 25–73 years; mean age: 57.2 years). The Changes in Sexual Functioning Questionnaire scoring indicated an overall sexual dysfunction in 33.8% of men and 58.1% of women.More than one-third (37.6%) of patients felt that RA had made their sex life more complicated, and 32.4% feared that this might someday be the case. In total, 29.2% patients had experienced sexual problems due to their RA treatment. Of the respondents who experienced RA-related fatigue, 46.5% reported that this impacted negatively on their sexual activity. The risk of one or more sexual health adversities was significantly correlated with female gender, older age, moderate or severe depression, moderate to moderately high loneliness, more than 2 comorbidities, and a fatigue score above 75 out of 100 on a visual analogue scale. Compared to the general population, significantly fewer patients with RA considered their sex life important, and significantly fewer patients appraised their current sex life as good or very good. Moreover, significantly more women with RA (32.1%) than women from the general population (15.7%) had not had any sex life during the past year. A vast majority of patients with RA (93.5% of women and 85.5% of men) had not discussed sexual issues with a health-care professional during the last 5 years. Of all, 32.5% would like health-care professionals to address sexual topics in the consultation occasionally.

Conclusion
Sexual dysfunction is highly prevalent in patients with RA, but the problems are not regularly addressed in consultations provided by the rheumatology department.

Published: September 2020

AbstractMarine hydroids, the polyp stage of hydrozoans, are assumed to be carnivores and play an important role in benthic-pelagic coupling processes by regulating zooplankton populations and transferring energy. The known hydroid diets mainly consist of zooplankton as well as some benthic diatoms and metazoans, almost all of which have smaller dimensions than the polyp. In the present study, a large-scale breeding failure of the early juveniles of the ivory shell Babylonia areolata (Mollusca: Gastropoda: Babyloniidae) was found in a local aquaculture farm in Fujian, China in July 2018. About 640,000 out of 800,000 early juveniles (80%) died due to predation by a millimetre-sized colonial hydroid species that was initially overlooked. The hydrozoan species was identified as Eirene sp. (Cnidaria: Hydrozoa: Eirenidae) via the integration of morphological and molecular data. A laboratory feeding experiment showed that the hydroid predation led to an overall mortality of ivory shell juveniles of up to 92.6% after 48 h. The predation process was observed in the laboratory and a video showing the entire process was prepared. This is the first report of hydroids preying on gastropod juveniles, revealing a previously unknown threat to mollusc aquaculture including ivory shells. Several management practices are suggested to mitigate this newly recognized threat.

AbstractBackgroundResearch on sickness absence has typically focussed on single diagnoses, despite increasing recognition that long-term health conditions are highly multimorbid and clusters comprising coexisting mental and physical conditions are associated with poorer clinical and functional outcomes. The digitisation of sickness certification in the UK offers an opportunity to address sickness absence in a large primary care population.MethodsLambeth Datanet is a primary care database which collects individual-level data on general practitioner consultations, prescriptions, Quality and Outcomes Framework diagnostic data, sickness certification (fit note receipt) and demographic information (including age, gender, self-identified ethnicity, and truncated postcode). We analysed 326 415 people's records covering a 40-month period from January 2014 to April 2017.ResultsWe found significant variation in multimorbidity by demographic variables, most notably by self-defined ethnicity. Multimorbid health conditions were associated with increased fit note receipt. Comorbid depression had the largest impact on first fit note receipt, more than any other comorbid diagnoses. Highest rates of first fit note receipt after adjustment for demographics were for comorbid epilepsy and rheumatoid arthritis (HR 4.69; 95% CI 1.73–12.68), followed by epilepsy and depression (HR 4.19; 95% CI 3.60–4.87), chronic pain and depression (HR 4.14; 95% CI 3.69–4.65), cardiac condition and depression (HR 4.08; 95% CI 3.36–4.95).ConclusionsOur results show striking variation in multimorbid conditions by gender, deprivation and ethnicity, and highlight the importance of multimorbidity, in particular comorbid depression, as a leading cause of disability among working-age adults.

SUMMARYA novel underwater vehicle configuration with an operating principle as the Sepiida animal is presented and developed in this paper. The mathematical equations describing the movements of the vehicle are obtained using the Newton–Euler approach. An analysis of the dynamic model is done for control purposes. A prototype and its embedded system are developed for validating analytically and experimentally the proposed mathematical representation. A real-time characterization of one mass is done to relate the pitch angle with the radio of displacement of the mass. In addition, first validation of the closed-loop system is done using a linear controller.

AbstractObjectives:To examine changes in micronutrient intake over 3 years and identify any associations between socio-economic, health, lifestyle and meal-related factors and these changes in micronutrient intakes among older men.Design:Prospective study.Setting:Dietary adequacy of individual micronutrient was compared to the estimated average requirement of the nutrient reference values (NRV). Attainment of the NRV for twelve micronutrients was incorporated into a dichotomised variable ‘not meeting’ (meeting ≤ 6) or ‘meeting’ (meeting ≥ 7) and categorised into four categories to assess change in micronutrient intake over 3 years. The multinomial logistic regression analyses were conducted to model predictors of changes in micronutrient intake.Participants:Seven hundred and ninety-four men participated in a detailed diet history interview at the third wave (baseline nutrition) and 718 men participated at the fourth wave (3-year follow-up).Results:The mean age was 81 years (range 75–99 years). Median intakes of the majority of micronutrients decreased significantly over a 3-year follow-up. Inadequacy of the NRV for thiamine, dietary folate, Zn, Mg, Ca and I were significantly increased at a 3-year follow-up than baseline nutrition. The incidence of inadequate micronutrient intake was 21 % and remained inadequate micronutrient intake was 16·4 % at 3-year follow-up. Changes in micronutrient intakes were significantly associated with participants born in the UK and Italy, low levels of physical activity, having ≥2 medical conditions and used meal services.Conclusions:Micronutrient intake decreases with age in older men. Our results suggest that strategies to improve some of the suboptimal micronutrient intakes might need to be developed and implemented for older men.
Poverty and food insecurity may increase as the threat of COVID-19 spreads
Authors: Pereira Marcos , Oliveira Ana Marlucia 
Published: September 2020

AbstractThis article discusses the relationship between both poverty and food insecurity (FI) and the COVID-19 pandemic, as well as presenting possible strategies and actions for increasing social protection in the fight against these conditions in the current epidemiological context, especially for low-income countries. This is a narrative review concerning COVID-19, poverty, and food and nutritional insecurity. The COVID-19 pandemic may increase poverty and FI levels, resulting from the absence of or weak political, economic and social interventions to maintain jobs, as well as compromised food production and distribution chains and reduced access to healthy foods in different countries around the world, especially the poorest ones, where social and economic inequality was already historically high; the pandemic heightens and uncovers the vulnerability of poor populations. Public policies focused on guaranteeing the human right to adequate food must be improved and implemented for populations in contexts of poverty with the aim of providing food security.
A review of radiation induced abscopal effect: combining radiotherapy and immunotherapy to treat the untreated distant metastatic tumours
Authors: Osei Ernest , Francis Ruth , Sheraz Lyba 
Published: September 2020

AbstractBackground:Radiotherapy is an effective and significant mode of definitive cancer treatment with well-established local tumour control success, especially in the treatment of localised tumours. Although, for metastatic disease, the role of radiotherapy has generally been limited to palliation of symptoms. In the treatment of metastatic diseases settings, the radiation therapy technique has always been confronted with the challenge of the simultaneous treatment of all of the various distant metastatic tumour sites, however, some recent evidence suggests that radiotherapy can potentially induce anticancer immune responses whose effectors potentially migrate to distant metastatic tumours to provoke their regression in cancer patients. Thus, unirradiated distant metastatic tumour sites can exhibit a delayed therapeutic response termed the abscopal effect.Materials and methods:This paper reports on a review of the abscopal effect, including its biological mechanism, the effect of radiation dose and fractionation regime and the timing of immunotherapy administration on radiotherapy-induced abscopal effect, the enhancement of radiotherapy-induced abscopal effects with immunotherapy, the effect of the location of the irradiated tumour and the radiotherapy of multiple tumour sites on the likelihood and effectiveness of inducing abscopal responses in the preclinical and clinical settings and also reports on some evidence of clinical observations in patients.Conclusions:Although abscopal effects of radiotherapy are still relatively rare in patients, it has gained a lot of interest due to recent development and use of immunotherapy strategies incorporating combinations of targeted immunomodulators and immune checkpoint blockade with radiation therapy. The enhancement of cancer immunotherapy could potentially enable the translation of the concept of abscopal effect into the clinics as a new strategy to induce therapeutically effective anti-tumour immune responses in cancer patients. The combination of radiotherapy and immunotherapy has the potential to expand the role of radiotherapy from a purely local tumour control treatment to play a significant role in advanced and metastatic tumour control and this could likely lead to a paradigm shift in the treatment of patients with metastatic cancer.
Neutron radiation effects on microcomputers in radiation therapy environments

Published: September 2020

AbstractAim:Microcomputers play an increasingly important role in the delivery of radiation therapy. Exposure to neutron irradiation can produce undesirable effects in modern microcomputers. The objective of this study is to measure acute and cumulative effects of neutron exposure of Intel-based microcomputers in photon and proton therapy treatment environments.Materials and methods:Multiple computers were irradiated with neutrons produced from MEVION S250 passive scattering proton therapy and from Varian 21EX Linear Accelerator photon therapy systems. The energy of the proton beam was 232 MeV and the photon beam energies were 6 and 18 MV. Rates of fatal errors in computer processing unit (CPU) cores were measured.Results:Varying rates of fatal system errors due to upsets in the CPU cores were observed. Post-exposure routine stress testing revealed no permanent hardware defects in the random access memory (RAM) or hard disk drive (HDD) of any tested systems. Microchip manufacturers fit increasingly high numbers of transistors in the same volume and the susceptibility to radiation thus increases.Conclusions:This work explores if the process size of a microchip is the dominant factor and also looked at the short- and long-term effects of neutron irradiation on modern microprocessors in a clinical environment. Additionally, methods of effective shielding are proposed.
Vegetable response to sulfentrazone soil residues at four planting intervals
Authors: Rachuy John S. , Fennimore Steven A. 
Published: September 2020

AbstractSulfentrazone was recently granted food-use tolerance approval for use on Brassica head and stem, as well as Brassica leafy vegetables. To date, one sulfentrazone registrant has listed those crops on its use label. In coastal California multiple crops per year including Brassica vegetables are grown in rapid succession; therefore, to avoid injury to rotational crops, herbicides used in those fields must be carefully selected. Given concerns about the relatively long soil persistence of sulfentrazone, studies were conducted to measure the response of direct-seeded carrot, lettuce, onion, spinach, and seeded tomato planted 3, 6, 9, and 12 mo after sulfentrazone application at 0, 112, 224, and 336 g ai ha−1. Eight plant-back studies were conducted during 2010–11 and 2012–13. Data collected were injury estimates, and stand and dry weights. Results indicate that it is safe to plant carrot and tomato 3 mo after sulfentrazone application at rates up to 336 g ai ha−1. Lettuce and green onion should not be planted within 9 mo of sulfentrazone application. Spinach should not be planted within 12 mo of sulfentrazone application.

Abstract. The aim of this research was to verify the psychometric properties of scores of the Polish version of the Future Time Perspective Scale (FTPS), developed by Carstensen and Lang (1996) . In Study 1, the sample consisted of N = 652 participants aged 18–79 years. We performed confirmatory factor analyses to verify the dimensional structure of future time perspective and obtained a three-factor solution. In Study 2, the sample consisted of 771 participants aged 18–75 years. The results confirmed that the scores of FTPS/PL are reliable and that the FTPS/PL has the three-dimensional structure of future time perspective. The following factors were extracted: Focus on Opportunity, Focus on Life, and Focus on Time. We also tested the measurement and structural invariance of the FTPS/PL in three age groups. The results showed the FTP scale after the removal of item 4 is a measure which can be used to compare individuals differing in age. Additionally, we examined the incremental validity of FTPS/PL for life satisfaction and positive and negative affect. In Study 3, the findings showed acceptable test–retest reliability what supports the possibility of using the Polish version of the FTPS in research.
Iron deficiency, fatigue and muscle strength and function in older hospitalized patients
Authors: Neidlein Sophia , Wirth Rainer , Pourhassan Maryam 
Published: September 2020

Abstract
Background/Objectives
Iron deficiency is common in older patients. We investigated whether iron deficiency is an independent risk factor for functional impairment, low muscle function, fatigue, and rehabilitation progress in older hospitalized patients.

Subjects/Methods
Two hundred twenty-four patients (age range 65–95 years; 67% females) who were consecutively admitted to a geriatric acute care ward participated in this prospective longitudinal observational study. Ferritin, iron, transferrin in serum, and blood hemoglobin were measured and current iron supplementation was recorded. Fatigue and comorbidity were measured using the fatigue severity scale and Charlson Comorbidity Index, respectively. Barthel Index, handgrip strength, and isometric knee extension strength were conducted at the time of hospital admission and before discharge.

Results
Ninety-one (41%) patients had iron deficiency in which the majority had functional iron deficiency (78/91, 86%). Absolute iron deficiency with and without anemia was diagnosed in 12 (13%) and one patients, respectively. Barthel Index and handgrip and knee extension strength significantly improved during hospitalization in iron deficiency and non-iron deficiency groups. Knee extension strength showed better improvement in iron-deficient patients receiving iron supplementation and iron supplementation during hospital stay was the main predictor for improvement in knee extension strength. Comorbidity, iron deficiency, and changes in handgrip strength were the major independent risk factors for poor improvement in Barthel Index during hospitalization. There were significant associations between patients’ fatigue and iron deficiency, comorbidity, and female gender.

Conclusion
Iron deficiency is an independent risk factor for fatigue and poor functional recovery among older hospitalized patients. Iron supplementation seems to be capable of improving functional performance.
