Hepatitis B and C viruses’ infection and associated factors among pregnant women in the Amhara region, Ethiopia: implications for prevention of vertical transmission.

Background Hepatitis virus infection is a major public health burden and silent killer disease in sub-Saharan Africa, including Ethiopia. Despite the recommendations of the World Health Organization, screening for hepatitis B virus (HBV) and hepatitis C virus (HCV) in pregnant women is not done routinely in public health institutions. Therefore, this study aimed to determine the burden of HBV and HCV and its associated factors among pregnant women in the Amhara region, Ethiopia. Methods A total of 1121 pregnant women were enrolled in the study. Data on sociodemographic and associated factors were collected using a structured questionnaire. Blood was collected from the pregnant women, and serum samples were tested for HBsAg and anti-hepatitis C virus antibody (anti-HCV) using ELISA. The status of HIV-infected pregnant women was collected from the records of their charts. SPSS version 20 was used for data analysis, and a binary logistic regression model was used to assess the relationship between factors associated with HBV and HCV infection. Results The seroprevalence of HBsAg and anti-HCV antibody were 4.6% and 1.6, respectively. The co-infection rate of HBV/HCV was 1.4% (1/69). Ten out of 52 HBV positive cases (19.2%) were co-infected with HIV. Only 20 (1.8%) pregnant women had the HBV vaccine. Interestingly, pregnant women with a history of multiple sexual partners (AOR = 3.2,95% CI,1.7–7.6), blood transfusion (AOR = 7.6,95% CI,2.9–16.9), family history of HBV (AOR = 3.5, 95% CI,1.7–7.6), being HIV-positive (AOR = 2.5, 95% CI,1-5.9), and tattooing (AOR = 2, 95% CI, 1-3.8) were significant predictors of HBV infection. Conclusions HBV and HCV infections were intermediate among pregnant women; risk factors were responsible for the majority of cases. Infants born from these infected mothers are at risk of infection. This calls for integration of HBV prevention into the PMTC of HIV. Thus, the provision of health education on HBV and HCV transmission, vaccination, and screening of all pregnant women routinely is essential for PMTCT.
Incidence Rates, Risk Factors, and Mortality Rates of Ventilator-Associated Pneumonia: A meta-analysis.

Background: Ventilator-associated pneumonia (VAP) is the second most common nosocomial infection in Intensive care units (ICUs) and is associated with the significant utilization of health-care resources. However, the incidence rates, risk factors and mortality rates of VAP are controversial.Methods: The Web of Science, EMBASE, PubMed and Cochrane Library databases through May 2020 were independently searched by two researchers to collect all relevant studies. Data including incidence rates, risk factors and mortality rates of VAP were extracted for the meta-analysis.Results: 24 studies, including 10 retrospective studies and 14 prospective studies on VAP were included in our analysis. In the meta-analysis, we found that the VAP rate was 20/1000 ventilator-days (95% confidence interval (CI) 17–22%). The data demonstrated that trauma (odds ratio (OR) 1.51; 95% CI 1.21-1.88), steroids use (OR 1.51; 95% CI 1.25-1.82), enteral feeding (OR 3.40; 95% CI 2.56-4.52), nasogastric tube placement (OR 2.96; 95% CI 1.75-5.00), tracheostomy (OR 3.65; 95% CI 1.93-6.90), reintubation (OR 6.08; 95% CI 4.62-8.00), central vascular catheter (CVC) placement (OR 3.83; 95% CI 2.55-5.77), blood transfusion(OR 1.75; 95% CI 1.16-2.64), H2 blockers use (OR 2.28; 95% CI 1.27-4.07) and Chronic obstructive pulmonary disease(COPD)(OR 1.24; 95% CI 1.07-1.44) were risk factors of VAP. When patients developed VAP, duration of ICU stay (OR 11.09; 95% CI 7.50-14.68) and duration of mechanical ventilation (MV) (OR 12.96; 95% CI 10.42-15.51) were significantly increased. What’s more, VAP was associated with an increased risk of mortality (OR 1.38; 95% CI 1.04-1.83). ConclusionsThis study may contribute to the development of improved infection control strategies for high-risk patients. Additional studies are needed in the future to clarify the incidence rates, risk factors and mortality rates of VAP.
Deadline Verification Using Model Checking

In this thesis, a new utility is presented for performing formal deadline checking of simple microcontroller programs at machine code level. The existing formal verification approaches and tools are studied and their weaknesses identified. Namely, source level techniques cannot guarantee cyclecount precise execution times, while machine code verification tools are few, not generally available, and usually heavily tailored to a specific processor, significantly reducing their usefulness. To counteract the weaknesses of current microcontroller verification tools, a novel hybrid approach is proposed and implemented. Machine code level model checking techniques are used for state space representation and verification of adherence to specification. Microcontroller memory and step behaviour is specified using a simple imperative language that can be manipulated using standard source code level techniques. This allows cycle-count based deadline checking, simple extension to other microcontrollers in addition to the implemented ATmega328P, and implementation of advanced techniques without dependence on the actual processor used. In addition to the core functionality, advanced techniques for handling nondeterminism, control flow generation, and simple cycle path reduction are implemented. The utility is tested, showing its usefulness for simple program deadline verification. The impact of various techniques used is discussed and promising future improvements are identified.
Choix d'imposition et interactions spatiales entre collectivités locales: un test sur les départements français

L'objectif de cet article est de tester econometriquement l'existence d'interactions spatiales entre les choix d'imposition des departements francais de metropole. Pour cela, un modele de choix fiscal avec auto-regression spatiale est specifie pour estimer la pente de la fonction de meilleure reponse qui relie le taux d'impot d'un departement aux taux votes par les departements voisins pour le meme impot. Nous montrons que pour l'annee 1999, l'hypothese d'interactions fiscales horizontales ne peut etre rejetee pour trois des quatre impots departementaux etudies, notamment pour la taxe professionnelle qui pese uniquement sur les entreprises. A l'inverse, la fixation du taux departemental de la taxe d'habitation, qui pese uniquement sur les menages, ne semble pas gouvernee par les decisions des departements concurrents. Ces resultats sont compatibles a la fois avec les modeles de concurrence fiscale a la Wildasin (1988) et ceux de concurrence par comparaison a la Besley et Case (1995a).

Inhibition of multiple SARS-CoV-2 proteins by an antiviral biomolecule, seselin from Aegle marmelos deciphered using molecular docking analysis

Abstract Our earlier experimental and computational report produced evidence on the antiviral nature of the compound seselin purified from the leaf extracts of Aegle marmelos against Bombyx mori Nuclear Polyhedrosis Virus (BmNPV). In the pandemic situation of COVID-19 caused by the SARS-COV-2 virus, an in silico effort to evaluate the potentiality of the seselin was made to test its efficacy against multiple targets of SARS-COV-2 such as spike protein S2, COVID-19 main protease and free enzyme of the SARS-CoV-2 (2019-nCoV) main protease. The ligand seselin showed the best interaction with receptors, spike protein S2, COVID-19 main protease and free enzyme of the SARS-CoV-2 (2019-nCoV) main protease with a binding energy of −6.3 kcal/mol, −6.9 kcal/mol and −6.7 kcal/mol, respectively. Docking analysis with three different receptors identified that all the computationally predicted lowest energy complexes were stabilized by intermolecular hydrogen bonds and stacking interactions. The amino acid residues involved in interactions were ASP1184, GLU1182, ARG1185 and SER943 for spike protein, SER1003, ALA958 and THR961 for COVID-19 main protease, and for SARS-CoV-2 (2019-nCoV) main protease, it was THR111, GLN110 and THR292. The MD simulation and MM/PBSA analysis showed that the compound seselin could effectively bind with the target receptors. The outcome of pharmacokinetic analysis suggested that the compound had favourable drugability properties. The results suggested that the seselin had inhibitory potential over multiple SARS-COV-2 targets and hold a high potential to work effectively as a novel drug for COVID-19 if evaluated in experimental setups in the foreseeable future.

Programi habilitacije funkcije gornjih udova kod djece s unilateralnom cerebralnom paralizom

This review presents the most researched and most effective methods used in (re) habilitation of the upper limbs of children with unilateral cerebral palsy – Constraint-Induced Movement Therapy and Bimanual Intensive Therapy. Children with unilateral cerebral palsy experience difficulties using their hands together secondary to disturbances that occur in the developing fetal or infant brain. The (more) affected hand is often disregarded during play and activities of daily living due to spasticity, muscle weakness, and sensory dysfunction. Although cerebral palsy is uncahnging condition that lasts throughout life, most studies and therapeutic approaches apply to children. Great progress has been made in preventinon and reduction of symptoms and increasing the functionality of children with unilateral cerebral palsy, but there are still large differences in the effectiveness of specific rehabilitation method when applied in a heterogeneous group of children with the same diagnosis. In order to determine the offset, duration and intensity of effective therapy, it is necessary to understand the neurological basis of this disorder. Effective approaches to upper limb therapy in children with unilateral cerebral palsy can be created and developed by linking the function of upper extremities and motor cortex with corticospinal tract integrity. In order to select the most appropriate approach according to the needs of the child and the capabilities of the family, the availability of evidence-based methods is important. Choosing the appropriate treatment approach increases the child's ability to reach his or her maximum functional potential with the restrictions imposed by structural brain injury.
Three methods of prophylaxis and therapy of innovative agonology, important from the perspective of personal safety

The expansion of the early twentieth century the eastern martial arts (judo and ju-jitsu then karate, kung-fu, taekwondo) for the European countries and the US was also the transfer of methodical traditions of training. Similarly defence art of aikido. The aim of this review is a recommendations of original Polish achievements in prevention of injuries as a result of falls, collisions and physical aggression, as well as the diagnosis and reduction of aggressiveness by the use of fun forms of martial arts. Judo therapy remains the specialty of many faculties Japanese universities. While Europe and the American continent penetrate systems therapeutic exercises: qigong, taichi, yoga etc. since 2007 three pillars of the WHO Falls Prevention Model are recommended. Authors of this Model does not directly recommend the necessity to teach the techniques of safe fall. The simplest and the most economic solution of the problem is teaching each person about safe falling as early as possible in their lives. The role of the scientists is still to publish the methods and study results so that the others could accept them or at first subject them to secondary verification process.
On the angular moment operators of attenuated ray transforms of scalar 3D-fields

— Under consideration are the operators of angular moments which map the values of generalized attenuated ray transforms (ART) into the set of symmetric p -tensor ﬁ elds. The di ﬀ erential relations between the values of ARTs of various orders, acting on stationary or dynamic source distributions f , serve as the basis for establishing the di ﬀ erential connections between the tensor ﬁ elds of angular moments of various orders k and ranks p . The particular cases are indicated allowing us to obtain some previously known results. Connections of the ARTs of order k with the problems of tomography and integral geometry as well as the established properties and connections between ARTs and angular moments can be useful as additional information when constructing the iterative algorithms for solving the problems of dynamic refraction tensor tomography
An image–temperature model of a microprobe used in wafer testing constructed by particle swarm optimization algorithm

The temperature of a minute object is typically measured by an infrared thermograph, a precise and expensive device. This study presents an image–temperature model constructed by particle swarm optimization algorithm to estimate the temperature according to the color image data on object’s surface. The demonstrated case was a palladium alloy microprobe used in wafer testing. Two series of conduction experiments were implemented to imitate the probing condition of the microprobe in wafer testing. Collecting the images captured from a digital video camera and the temperatures measured by the infrared thermograph, the correlations between the color image data and their corresponding temperatures were investigated. An image–temperature model is further constructed by the particle swarm optimization algorithm based on the image components of the RGB and HSV models of the examined pixel. The model developed provides valuable references for making out the electrothermal effect of the palladium alloy microprobe used in wafer testing.
Family Housing: Dream or Nightmare?

The home has always been the best investment that an American family could make, and in current periods of inflation and economic uncertainty this is particularly true. Unfortunately, some families now must decide whether the investment is worth continuing. For the family that plans carefully and foregoes some spending for recreation, eating out, and other marginal expenses, the home can become the best investment possible.
Use of indicators as a tool to measure sustainability in agroecosystems of arid land, San Juan, Argentina = Uso de indicadores como herramienta para medir la sustentabilidad en agroecosistemas de tierras áridas, San Juan, Argentina

The main objective of this study was to determine the sustainability status of three agroecosystems in arid areas, and to identify the critical aspects that limit it, through the use of economic, ecological and socio-cultural indicators. Three agroecosystems (AE) were selected from the Department of 25 de Mayo, San Juan. Its main economic activity is goat farming and, to a lesser extent, cultivation of orchards, as well as subsistence economic activities. To determine the state of sustainability, the indicators were selected and subsequently standardized and weighted according to their relative importance with respect to sustainability. The results indicated that none of the dryland AE achieves sustainability simultaneously in its three dimensions. The systemic analysis through indicators showed that the critical variables are food self-sufficiency, water access, livestock survival, and technical assistance, among others. The methodology used is simple, allowing to detect the sustainability status of the three EAs, and to identify the critical variables that jeopardize the permanence of the AE over time.

Does Distance Influence Profitability of Bank Customers

This study aims to identify whether customers who live further away from bank branches where they opened their checking accounts are as profitable as those who live closer. For this purpose, it were selected 30 bank branches of one of the largest retail banks in Brazil and it was used analysis of variance in order to compare customer mean profitability of these branches among primary, secondary and fringe trading areas for those customers who receive their salaries by the bank and also for those who don´t receive. Regardless of whether customers receive or not their salaries by the bank, those who live further from the branches where they opened their checking accounts are as profitable as those who live closer and, in some cases, they are more profitable. So, Banks must take into account all customers of a branch and not only those who live closer it in order to develop strategies for customer retention and for increasing profitability provided by customers. It was also possible to conclude that trading area theory according to which the importance of each one of three trading areas in relation to profitability provided by customer is different, isn´t applied for banks, because there aren´t no significant differences in profitability provided by customers according to the distance they live from the branches. Generalizations are limited to Sao Paulo (Brazil) city and active individual customers.
