Published: September 2021

Lagrangian analysis is becoming increasingly important to better understand the ocean's biological and biogeochemical cycles. Yet, biologists and chemists often lack the technical skills required to set up such analyses. Here, we present a new product of pre-computed ocean Lagrangian trajectories (OLTraj) targeting non-expert users, and demonstrate how to use it by means of worked examples. OLTraj is based on satellite-derived geostrophic currents, which allows one to directly compare it with other in-situ or satellite products. We anticipate that OLTraj will foster a new interest in Lagrangian applications in ocean biology and biogeochemistry.

Aims This study aimed to evaluate the accuracy of implant placement with robotic-arm assisted total hip arthroplasty (THA) in patients with developmental dysplasia of the hip (DDH). Methods The study analyzed a consecutive series of 69 patients who underwent robotic-arm assisted THA between September 2018 and December 2019. Of these, 30 patients had DDH and were classified according to the Crowe type. Acetabular component alignment and 3D positions were measured using pre- and postoperative CT data. The absolute differences of cup alignment and 3D position were compared between DDH and non-DDH patients. Moreover, these differences were analyzed in relation to the severity of DDH. The discrepancy of leg length and combined offset compared with contralateral hip were measured. Results The mean values of absolute differences (postoperative CT-preoperative plan) were 1.7° (standard deviation (SD) 2.0) (inclination) and 2.5° (SD 2.1°) (anteversion) in DDH patients, and no significant differences were found between non-DDH and DDH patients. The mean absolute differences for 3D cup position were 1.1 mm (SD 1.0) (coronal plane) and 1.2 mm (SD 2.1) (axial plane) in DDH patients, and no significant differences were found between two groups. No significant difference was found either in cup alignment between postoperative CT and navigation record after cup screws or in the severity of DDH. Excellent restoration of leg length and combined offset were achieved in both groups. Conclusion We demonstrated that robotic-assisted THA may achieve precise cup positioning in DDH patients, and may be useful in those with severe DDH.

ObjectiveChagas disease (CD) globalization facilitated the co-infection with Human Immunodeficiency Virus (HIV) in endemic and non-endemic areas. Considering the underestimation ofTrypanosoma cruzi (T.cruzi)-HIV co-infection and the risk of life-threatening Chagas Disease Reactivation (CDR), this study aimed to analyze the major co-infection clinical characteristics and its mortality rates.MethodsThis is a cross-sectional retrospective multicenter study of patients with CD confirmed by two serological or one parasitological tests, and HIV infection confirmed by immunoblot. CDR was diagnosed by direct microscopy with detection of trypomastigote forms in the blood or other biological fluids and/or amastigote forms in inflammatory lesions.ResultsOut of 241 patients with co-infection, 86.7% were from Brazil, 47.5% had <200 CD4+T cells/μL and median viral load was 17,000 copies/μL. Sixty CDR cases were observed. Death was more frequent in patients with reactivation and was mainly caused by CDR. Other causes of death unrelated to CDR were the manifestation of opportunistic infections in those with Acquired Immunodeficiency Syndrome. The time between the co-infection diagnosis to death was shorter in patients with CDR. Lower CD4+cells count at co-infection diagnosis was independently associated with reactivation. Similarly, lower CD4+cells numbers at co-infection diagnosis and male sex were associated with higher lethality in CDR. Additionally, CD4+cells were lower in meningoencephalitis than in myocarditis and milder forms.ConclusionThis study showed major features onT.cruzi-HIV co-infection and highlighted the prognostic role of CD4+cells for reactivation and mortality. Since lethality was high in meningoencephalitis and all untreated patients died shortly after the diagnosis, early diagnosis, immediate antiparasitic treatment, patient follow-up and epidemiological surveillance are essentials inT.cruzi/HIV co-infection and CDR managements.
Occult focal cortical dysplasia may predict poor outcome of surgery for drug-resistant mesial temporal lobe epilepsy
Authors: Nowak Arkadiusz , Bala Aleksandra 
Published: September 2021

PurposeThe results of surgery in patients with mesial temporal lobe epilepsy (MTLE) associated with hippocampal sclerosis (HS) are favorable, with a success rate over 70% following resection. An association of HS with focal cortical dysplasia (FCD) in the temporal lobe is one of the potential causes for poor surgical outcome in MTLE. We aimed to analyzed seizure outcome in a population of MTLE patients and recognize the role of occult FCD in achieving postoperative seizure control.MethodsWe retrospectively analyzed postoperative outcomes for 82 consecutive adult patients with the syndrome of MTLE due to HS, who had no concomitant lesions within temporal lobe in MRI and who underwent surgical treatment in the years 2005–2016, and correlated factors associated with seizure relapse.ResultsAt the latest follow-up evaluation after surgery, 59 (72%) were free of disabling seizures (Engel Class I) and 48 (58,5%) had an Engel Class Ia. HS associated with FCD in neocortical structures were noted in 33 patients (40%). Analyzes have shown that dual pathology was the most significant negative predictive factor for Engel class I and Engel class Ia outcome.ConclusionsThe incidence of dual pathology in patients with temporal lobe epilepsy seems to be underestimated. An incomplete epileptogenic zone resection of occult focal temporal dysplasia within temporal lobe is supposed to be the most important negative prognostic factor for seizure freedom after epilepsy surgery in MTLE-HS patients. The study indicates the need to improve diagnostics for other temporal lobe pathologies, despite the typical clinical and radiological picture of MTLE-HS.

ObjectiveThis study aimed to determine the gender factors that influence regular exercise in patients with non-insulin-dependent diabetes mellitus (NIDDM) in Korea.MethodsA total of 1,432 patients with NIDDM were recruited using raw data from the Korea National Health and Nutrition Survey conducted between 2016 and 2018. SAS 9.4 was adopted for data analyses, and the distributional difference was measured with multinomial logistic regression and Rao-Scott x2 statistics to identify the factors that influence the regular physical activities of patients. that the analysis only provides associations.ResultsBased on general characteristics, health behaviors, and conditions, patients with NIDDM in Korea were less physically active. In addition, patients with higher educational attainment, higher income, and higher subjective health conditions had a higher odds ratio for regular exercise. Meanwhile, the ratio was lower for smokers and those stressed up.ConclusionA professional guide for the initial phase of training and consistent management is required to increase the involvement of patients with NIDDM in regular exercise. Therefore, it is important to maintain their motivation to continue exercising. Rather than providing a universal guideline, it is more important to provide customized programs and management plans which reflect factors that influence their engagement in physical activities, such as individual physical strength, stress level, alcohol consumption, and arthritis.

Published: September 2021

IntroductionEven though menstruation is a normal biological process, adolescents are facing managing their menstruation when they are at school. It causes girls to miss their class on average three days every month. Studies in some countries showed that the magnitude of menstrual hygiene management problems is higher in rural adolescent girls, but little is known in the Ethiopia context. The objective of this study was to assess and compare menstrual hygiene management practices among rural and urban schoolgirls, Northeast, Ethiopia.MethodsAn institution-based comparative cross-sectional study was employed among 1078 schoolgirls (539 urban and 539 rural) from February to March 2020. The participants were selected using a multi-stage sampling technique. A structured self-administrative questionnaire and observational checklist were used for data collection. Bivariate and multivariable logistic regression analysis with a 95% confidence interval was employed. A P- value less than 0.05 was used to declare statistical significance.ResultsOverall, the magnitude of good menstrual hygiene practice was 52.9% (95%CI: 50.3%-56.5%), which was 65.9% (95% CI: 62.8%-70.7%) among urban and 39.9% (95% CI: 36.2%-44.6%) among rural schoolgirls. Among urban schoolgirls, the odds of good menstrual hygiene management practice was higher for girls aged below 18 years (AOR = 1.58, 95%CI: 1.05–2.39), learned about menstrual hygiene at school (AOR = 1.89, 95%CI: 1.21–2.97), heard about menstrual hygiene before menarche (AOR = 4.98, 95%CI: 2.71–9.13), and discussed menstrual hygiene with parents (AOR = 2.56, 95%CI: 1.25–5.27). Whereas, the odds of good menstrual hygiene management practice was higher among those who were knowledgeable on menstrual hygiene (AOR = 5.47, 95%CI: 3.68–8.12), those who learned about menstrual hygiene at school (AOR = 1.75, 95%CI: 1.13–2.70), and girls who heard about menstrual hygiene before menarche (AOR = 3.34, 95%CI: 1.44–7.76) in rural schoolgirls.ConclusionsThough the overall menstrual hygiene practice was low, it was relatively better among urban schoolgirls. This calls for more effort to solve these problems and achieve sustainable development goals. Therefore, education and awareness creation on menstrual hygiene for schoolgirls, even before menarche at both settings should be strengthened. Encouraging parent-adolescent discussion on menstrual hygiene would have paramount importance, particularly to urban schoolgirls.

Background
Few studies have quantified aerosol concentrations of SARS-CoV-2 in hospitals and long-term care homes, and fewer still have examined samples for viability. This information is needed to clarify transmission risks beyond close contact.

Methods
We deployed particulate air samplers in rooms with COVID-19 positive patients in hospital ward and ICU rooms, rooms in long-term care homes experiencing outbreaks, and a correctional facility experiencing an outbreak. Samplers were placed between 2 and 3 meters from the patient. Aerosol (small liquid particles suspended in air) samples were collected onto gelatin filters by Ultrasonic Personal Air Samplers (UPAS) fitted with <2.5μm (micrometer) and <10 μm size-selective inlets operated for 16 hours (total 1.92m3), and with a Coriolis Biosampler over 10 minutes (total 1.5m3). Samples were assayed for viable SARS-CoV-2 virus and for the viral genome by multiplex PCR using the E and N protein target sequences. We validated the sampling methods by inoculating gelatin filters with viable vesicular stomatitis virus (VSV), and with three concentrations of viable SARS-CoV-2, operating personal samplers for 16hrs, and quantifying viable virus recovery by TCID50 assay.

Results
In total, 138 samples were collected from 99 rooms. RNA samples were positive in 9.1% (6/66) of samples obtained with the UPAS 2.5μm samplers, 13.5% (7/52) with the UPAS 10μm samplers, and 10.0% (2/20) samples obtained with the Coriolis samplers. Culturable virus was not recovered in any samples. Viral RNA was detected in 15.1% of the rooms sampled. There was no significant difference in viral RNA recovery between the different room locations or samplers. Method development experiments indicated minimal loss of SARS-CoV-2 viability via the personal air sampler operation.

BACKGROUND. One of the priority directions in the development of the health care system is to reduce the medical and social damage caused by the increase in the prevalence of diabetes mellitus (DM). From this point of view, the development of a diabetes register is very important as the main information and analytical platform for clinical and epidemiological monitoring of diabetes in the Russian Federation (RF).AIMS. The aim of our study was to analyze a dynamic (2016–2020) of the epidemiological characteristics of diabetes mellitus in the Russian Federation (prevalence, morbidity, mortality), the prevalence of complications, the level of HbA1c and the dynamics of the structure of glucose-lowering therapy (GLT) according to the Federal Diabetes Register (FDR).MATERIALS AND METHODs. The database of FRD (http://diaregistry.ru) 84 regions of the RF. The data are presented in dynamics 2016→2020.RESULTS. The total number of DM patients in the RF as of 01.01.2021 was 4,799,552 (3.23% of the population), including: Type 1 (T1) — 5.5% (265.4 ths) , T2 — 92.5% (4.43 million), other DM types — 2.0% (99.3 ths). The dynamics of prevalence was 168.7→180.9/100 ths people with T1, and 2709 → 3022/100 ths people with T2; morbidity in T1 10.5→7.7/100 ths population, in T2 219.6→154.2/100 ths population. Age and sex characteristics: the proportion of men in T1 — 54%, in T2 — 30%; the max proportion of patients with T1 at the age of 30–39 years, T2 65–69 years. Mortality: T1 3.0 → 2.7/100 ths population, T2 87.7→93.9/100 ths of the population, the main cause of death was cardiovascular: in T1 38,1% cases, in T2 — 52,0%. Life expectancy (average age of death of patients): T1 was 53.2years, the dynamics in males 50.7 → 50.5years, ­females 58.7→55.2years; in T2 — 73.5 years, males 70.2→70.1years, females 75.7→75.4 years. The dynamic of DM duration until the death: in T1 17.4→19.0 years; in T2 11→11.4 years. The incidence of diabetic complications in T1 and T2 patients: neuropathy 43.3% and 24.4%, nephropathy (CKD) 25.9% and 18.4%, retinopathy 31.7% and 13.5%, respectively. The ­proportion of ­patients with HbA1c <7%: in T1 32.3%→36.9%, in T2 51.9%→52.1%, with HbA1c ≥ 9.0% in T1 23.1%→18.7% , in T2 8.9%→8.0%. The structure GLT in T2 patients: glucose lowering medications (GLM) — 76.2% (monotherapy — 44.1%; ­combination of 2 GLM — 28.9%, 3 GLM — 3.2%), insulin therapy in 18,8%, without drug therapy in 4.9%.CONCLUSIONS. The performed analysis demonstrates the importance of dynamic assessment of epidemiological characteristics and monitoring of clinical data on patients with diabetes through a registry for assessing the quality of diabetes care and the prospects for its development.

Published: September 2021

Abstract
The automation of quality control in manufacturing has made great strides in recent years, in particular following new developments in machine learning, specifically deep learning, which allow to solve challenging tasks such as visual inspection or quality prediction. Yet, optimum quality control pipelines are often not obvious in specific settings, since they do not necessarily align with (supervised) machine learning tasks. In this contribution, we introduce a new automation pipeline for the quantification of wear on electrical contact pins. More specifically, we propose and test a novel pipeline which combines a deep network for image segmentation with geometric priors of the problem. This task is important for a judgement of the quality of the material and it can serve as a starting point to optimize the choices of materials based on its automated evaluation.
Model-based control of wind turbines for active power control
Authors: Pöschke Florian , Schulte Horst 
Published: September 2021

AbstractThis paper addresses the model-based control design of wind turbines using the sector-nonlinearity approach. Building on the Takagi-Sugeno framework, this approach introduces an exact representation of the underlying nonlinear dynamics into the control design. The unified wind turbine control design followed in this study addresses both established (power optimization in the partial load and power limitation in the full-load region) and further requirements for wind turbine systems. An important control objective for wind turbines is the ability to support grid operators with frequency control. To achieve this, an active power control scheme is inherited in the design model such that changes in the power generation can be balanced and the grid frequency may be controlled. First, the derivation of models designed to achieve the multiple control objectives is presented in detail. After that, a unified synthesis procedure based on linear matrix inequalities is discussed and applied. Finally, the quality of the design process is evaluated through simulation studies for representative scenarios.
Energy capable clustering method for extend the duration of IoT based mobile wireless sensor network with remote nodes
Authors: Giji Kiruba  , Benita  
Published: September 2021

Abstract
The energy performance of IoT-MWSNs may be augmented by using a suitable clustering technique for integrating IoT sensors. Clustering, on the other hand, requires additional overhead, such as determining the cluster head and cluster formation. Environmental Energy Attentive Clustering with Remote Nodes is a unique environmental energy attentive clustering approach for IoT-MWSNs proposed in this study methodology (E2ACRN). Cluster head (CH) in E2ACRN is entirely determined by weight. The residual energy of each IoT sensor and the local average energy of all IoT sensors in the cluster are used to calculate the weight. Inappropriately planned allocated clustering techniques might result in nodes being too far away from CH. These distant nodes communicate with the sink by using more energy. The ambient average energy, remoteness among IoT sensors, and sink are used to determine whether a distant node transmits its information to a CH in the previous cycle or to sink in order to lengthen lifetime. The simulation results of the current technique revealed that E2ACRN performs better than previous clustering algorithms.
