Predictive value of subendometrial – endometrial blood flow assessment by transvaginal 3D power doppler on the day of HCG on clinical outcome of IVF cycles

Background: The objective of the study was to evaluate the role of subendometrial-endometrial blood flow assessment by 3D Tran-vaginal Power Doppler in predicting pregnancy outcome in IVF-ET cycles. The study was a prospective, non-randomized clinical study. Methods: A total of 107 infertile women undergoing their first IVF-ET cycle with good response were taken for study (From March 2014 to Nov 2014 at Jaipur Fertility Centre, ART unit of Mahatma Gandhi University of Medical Sciences & Technology). Women with Tubal factor, Male factor and unexplained infertility were included in the study. Those with past h/o Genital Koch’s and hypo menorrhea were excluded. Assessment of subendometrial-endometrial blood flow was done on the day of HCG with endometrial thickness ≥ 6.5mm by Tran-vaginal 3D- Power Doppler. Results: There was no significant difference in mean age, duration of infertility, BMI, cause of infertility, stimulation protocol, serological hormone levels, number of mature oocytes, number of good quality embryos and mean endometrial thickness on the day of HCG. According to Doppler study (3D-Power Doppler), women with blood flow to zones 1, 2 and 3 were categorized in to groups A (n=15), B (n=36) and C (n=56). Overall pregnancy rate was 32.71%. The clinical pregnancy rate was significantly higher in Group C in comparison of Group B and A (42.85% vs. 27.77% and 6.66%). Similarly implantation rate was also higher in group C (23.20% vs. 11.22% and 2.38%). Conclusions: The presence of good subendometrial-endometrial vascularity significantly improves pregnancy outcome in IVF-ET cycles in our study.
PartialSync: Efficient Synchronization of a Partial Namespace in NDN

Named Data Networking (NDN) is an evolving Future Internet Architecture where data is a first-class entity. Data synchronization plays an important role in NDN similar to transport protocols in IP. Some distributed applications, such as news and weather services, require a synchronization protocol where each consumer can subscribe to a different subset of a producer’s data streams. In this paper, we propose PartialSync which aims to efficiently address this synchronization problem. We use names in PartialSync messages to carry producer’s latest namespace information and each consumer’s subscription information, which allows producers to maintain a single state for all consumers and enables consumers to synchronize with any producer that replicates the same data. We represent the latest names in a producer’s data streams using an Invertible Bloom Filter (IBF), which allows efficient computation of set differences. By comparing the differences between its old IBF and new IBF, the producer can generate a list of new data names that have been produced in the period between the old and new IBF. Using this list and a consumer’s subscription information, the producer can notify the consumer if new data matching the subscription has been produced. We have implemented PartialSync in the NDN codebase and are using it to develop a prototype building management system where users can subscribe to any subset of data generated by the many sensors and actuators in buildings.
Perceived support, substance use, suicidal ideation, and psychological distress among military-connected adolescents

abstract Military-connected adolescents may be at increased risk for poor behavioral health outcomes related to the stressors of war. This study examined the co-occurrence of substance use and mental health problems among military-connected youth compared to their non-military-connected counterparts. Data from youth in ninth- and eleventh-grade classes in six military-connected school districts completed the California Healthy Kids Survey in 2011 (n = 9,122). Latent class analysis was utilized to examine co-occurring substance use and mental health issues. Military connection (parent, sibling, or none) and five measures of perceptions of school and community support were included in the model. The analysis revealed four different groups. As the probability of co-occurrence increased, the chance that youth had a sibling serving and that they perceived lower support from the military and other military families increased. These findings support a need for additional research on the adolescent siblings of military service persons. Clinicians should add questions to ascertain close family member service and screening for co-occurring substance use and mental health to their standards of practice related to working with military connected youth.
Automatic Object-Oriented Curriculum Generation for Reinforcement Learning

Even though Reinforcement Learning (RL) is one of the most used techniques to train autonomous agents, learning complex tasks takes a very long time. One way to learn faster is dividing a complex task into several simple subtasks, building a Curriculum that guides Transfer Learning (TL) methods to reuse knowledge in a convenient sequence. However, the state-of-the-art in Curriculum Learning for RL does not take into account the used TL technique to build specialized Curricula, leaving the burden of a careful subtask selection to a human. We here rely on the Object-Oriented task description to guide both the Curriculum generation and knowledge reuse procedures, autonomously building object-based Curricula. Our initial experiments show that our proposal achieves a better performance while requiring less computation time when compared to the state-of-the-art technique.
Predicting Canopy Nitrogen Content in Citrus-Trees Using Random Forest Algorithm Associated to Spectral Vegetation Indices from UAV-Imagery

The traditional method of measuring nitrogen content in plants is a time-consuming and labor-intensive task. Spectral vegetation indices extracted from unmanned aerial vehicle (UAV) images and machine learning algorithms have been proved effective in assisting nutritional analysis in plants. Still, this analysis has not considered the combination of spectral indices and machine learning algorithms to predict nitrogen in tree-canopy structures. This paper proposes a new framework to infer the nitrogen content in citrus-tree at a canopy-level using spectral vegetation indices processed with the random forest algorithm. A total of 33 spectral indices were estimated from multispectral images acquired with a UAV-based sensor. Leaf samples were gathered from different planting-fields and the leaf nitrogen content (LNC) was measured in the laboratory, and later converted into the canopy nitrogen content (CNC). To evaluate the robustness of the proposed framework, we compared it with other machine learning algorithms. We used 33,600 citrus trees to evaluate the performance of the machine learning models. The random forest algorithm had higher performance in predicting CNC than all models tested, reaching an R2 of 0.90, MAE of 0.341 g·kg−1 and MSE of 0.307 g·kg−1. We demonstrated that our approach is able to reduce the need for chemical analysis of the leaf tissue and optimizes citrus orchard CNC monitoring.
Antibacterial Activity against Methicillin-Resistant Staphylococcus aureus of Colloidal Polydopamine Prepared by Carbon Dot Stimulated Polymerization of Dopamine

A simple one-step process for the polymerization of dopamine has been developed using nitrogen-doped carbon dots (N@C–dots) as the sole initiator. The synthesized amorphous polydopamine (PDA)-doped N@C–dots (PDA–N@C–dots composite) exhibited a negative charge of –39 mV with particle sizes ranging from 200 to 1700 nm. The stable colloidal solution was active against methicillin-resistant Staphylococcus aureus (MRSA), a Gram-negative bacterium. The strong adhesion of the polymer to the bacterial membrane resulted in a limited diffusion of nutrients and wastes in and out of the cell cytosol, which is a generic mechanism to trigger cell death. Another possible route is the autoxidation of the catechol moiety of PDA to form quinone and release reactive oxygen species (ROS) such as superoxide radicle and hydrogen peroxide, two well-known ROS with antimicrobial properties against both Gram-negative and Gram-positive bacteria.
Managers as skill-based and trust-based resources: Evidence from internal mobility in corporate groups

The ability to redeploy and recombine internal resources is an important source of competitive advantage for rms, and a key strategic resource is top management. This study proposes two ways in which managers can add value to their organizations: as skill-based and trust-based resources. We argue that, depending on which one of these two attributes is preponderant, patterns of internal mobility will di¤er. Skilled managers will tend to move to units where the bene ts of controlling shareholders are higher. Trustworthy managers will tend to move to units where extending the control of shareholders is most important. Using a novel dataset on managerial mobility within corporate groups, we nd evidence consistent with these arguments. Our results deepen our understanding of the factors a¤ecting managerial mobility in multi-unit organizations, and have implications for the theory of the rm and the role of family management. Keywords: Redeployment, management, ownership, corporate governance, family groups. JEL Classi cation: D23, G32, L23.
Emergence of vancomycin resistant enterococci in a tertiary care hospital in South India

Objectives: The present study was undertaken in a tertiary health center in VIMS teaching hospital, Bellary, to characterize enterococcal isolates obtained from clinical specimens, study their antimicrobial susceptibility pattern including vancomycin resistance. Methods: A total of 40 enterococcal isolates from various clinical samples of hospitalised patients during the study period June 2011 to May 2012, were identified by standard laboratory procedures. Antibiotic susceptibility testing was performed by Kirby Bauer disk diffusion method to detect vancomycin resistant enterococci (VRE) as recommended by Clinical Laboratory Standards Institute (CLSI). Results: Out of total 40 isolates of enteroccocci, 38 were Enterococcus faecalis and 2 were Enterococcus faecium. Resistance patterns of the isolates were 100%, 90%, 85%, 72.5%, 60% and 65% to cephalexin, gentamicin, cotrimoxazole, erythromycin, penicillin and tetracycline, respectively. Two isolates (5%) showed vancomycin resistance. All the isolates were sensitive to linezolid. Conclusions: This study shows multidrug resistance (MDR) and emergence of VRE in our hospital requiring prompt and effective screening methods for VRE in all isolates obtained from clinical samples and also an urgent need for more rational and restricted use of antimicrobials.
A MINIMUM FOLLOW-UP OF FIVE YEARS

J Bone Joint Surg [Br] 2005;87-B:167-70. Received 30 October 2003; Accepted after revision 5 March 2004 We report the survival at five years of 144 consecutive metal-on-metal resurfacings of the hip implanted between August 1997 and May 1998. Failure was defined as revision of either the acetabular or femoral component for any reason during the study period. The survival at the end of five years was 98% overall and 99% for aseptic revisions only. The mean age of the patients at implantation was 52.1 years. Three femoral components failed during the first two years, two were infected and one fractured. A single stage revision was carried out in each case. No other revisions were performed or are impending. No patients were lost to follow-up. Four died from unrelated causes during the study period. This study confirms that hip resurfacing using a metal-on-metal bearing of known provenance can provide a solution in the medium term for the younger more active adult who requires surgical intervention for hip disease.

Introduction: Patient safety is one of the important components in quality improvement of health services. This study aimed to evaluate aspects of patient safety culture and identification of intervention priority in the Seidolshohada Hospital. Method: The study was a cross – sectional on the community of nurses, midwives, and the staff in radiology and laboratory. Sampling method was census. Data collection was conducted using standard questionnaire of hospital survey on patient safety culture (HSOPSC). The data was analyzed descriptive statistics (frequency, percentage, mean) using software spss-16. According questionnaire guide in each aspects average at least 70 percent positive safety culture, safety culture medium 70-50, and 50 were considered poor safety culture. Results: In this study, the largest group participant was nurse / midwife (66.7%). Most participants work experience 5-1 years (46.7%) and 59-40 hours worked per week (46.7%). The interaction with the patients, 95% of participants in direct contact with patients and 5% indirect communication with patients. The dimension that received the highest score was "organizational learning and continuous improvement" (74.5%) and the dimension with the lowest scores was "Non-punitive response to error" (49.1%). The other aspects of safety culture was at a moderate level. Conclusion: This study emphasizes the need to promote a culture of patient safety in terms of expectations and the Supervisor/ Manager to improve safety, communication and provide feedback on the errors, the frequency of reporting accidents, improve teamwork between the unit and the non-punitive response to error.
Efecto del tipo de carbohidrato en el concentrado sobre el consumo de alimento de vacas lecheras en pastoreo # Effect of the type of carbohydrate on the concentrate of food intake of dairy cows on pasture

SUMMARY Two experiments were carried out to evaluate two sources of carbohydrate (fibrous and starchy) in concentrate supplement for high producing dairy cows fed spring pasture. In experiment 1, 12 Friesian cows yielding 33.0 kg/d, were assigned to a 3x3 Latin square design with periods of 21 days. In experiment 2, 27 Friesian cows yielding 29.3 kg/d were assigned to a completely randomized design for 45 days. For both experiments, the treatments included: grazing alone (SP), grazing plus 6 kg/d of sugar beet pulp-based concentrate (Coseta) and grazing plus 6 kg/d of cereal-based concentrate (Cebada). The cows were supplemented twice a day and managed under a strip grazing system on pasture consisting mainly of perennial ryegrass. In Experiment 1 the concentrate diet contained 17.0% crude protein (CP) in the dry matter (DM), with 11.9% CP in Experiment 2. In experiment 1 herbage dry matter intake (10.7 kg/day), total dry matter intake (16.0 kg/day) and grazing behavior were similar for sugar beet pulp-based concentrate and cereal-based concentrate. In experiment 2 herbage dry matter intake (12.4 kg/d), total dry matter intake (17.4 kg/d) and grazing behavior were similar for the supplemented treatments. Unsupplemented cows had a higher herbage dry matter intake in experiment 1 (15.4 kg/day) and lower total dry matter intake (14.2 kg/day) in experiment 2, than the supplemented cows (P<0.05). The results suggest that carbohydrate source in concentrate supplement, did not affect food intake and grazing behavior of dairy cows on these experiments.
The Effects of International Study Tours in the Decision of Students to Go to Work Abroad - The Example of the GGS' IST to Turkey and Russia

Until now, much of the research on International Study Tours has focused on the learning opportunities and intercultural advantages of participating in such mobility programmes. However, there has been limited literature on the relationship between joining these study trips and the motivation that students might get to start working abroad. This new research promi- ses many advantages for our globalized world as more and more companies struggle to get the right people at the right place – sometimes without success. The possibility of participating in such a study programme could not only contribute to preparing a future world manager, but it could also prompt him to accept a top position in a country other than his own.
Abordagem da sexualidade no diálogo entre pais e adolescentes

Objective: To evaluate the approach to sexuality in the dialogue between parents and adolescents and to describe how nursing can intervene positively in this context. Methods: This descriptive and qualitative study involved 22 parents selected by simple sampling. A semistructured form was used for data collection, and the Collective Subject Discourse method was used to analyse the results. Results: The study included three categories: dialogue between parents and children on sexuality; topics addressed in the dialogue between parents and children; and counselling and difficulties experienced by parents. Conclusion: Parents experienced difficulties when addressing sexuality and addressed this topic only superficially. In this context, nursing plays an important role in the sexual education of adolescents and in the orientation provided in the family and school setting.
PPIUCD versus interval IUCD (380a) insertion: a comparative study in a referral hospital of Karnataka, India

Background: Comparative evaluation of PPIUCD and interval IUCD in terms of incidence of failure, expulsions, bleeding p/v and other complications. Methods: Total 200 willing women after counseling in antenatal, early labour or post natal were inserted PPIUCD after excluding chorioamnionitis, PROM >18hrs, unresolved PPH, puerperal sepsis. Another 100 willing women were inserted interval IUCD after excluding contraindications. All were followed up to 6 months. Results: Expulsions rate was significantly higher in PPIUCD as compared to interval insertions (5.5% v/s 5%). Number of removal of IUCD was almost similar in both the groups (6.5% V/S 7%). Common causes of PPIUCD removal were social. Conclusions: Postpartum inserting of IUCD is safe effective, feasible and reversible method of contraception.
Perceived attitudes and benefits towards teaching evidence based practice among physiotherapy lecturers at tertiary institutions in South Africa

Evidence-based practice (EBP) is gaining momentum in the physiotherapy profession. The main focus of EBP, however, has been in clinical practiceand in the move towards global EBP, very little attention has been given tothe contents of physiotherapy education programs. There is very limitedinformation regarding the attitudes of health professional lecturers, especially physiotherapists, towards the teaching of evidence based practice.The aim of this study was to determine the attitudes of lecturers and use ofevidence in teaching among physiotherapists at tertiary institutions in South Africa. The study employed a within stage mixed model approach. The study population consisted of all physiotherapy lecturers at the 8 training institutions in South Africa. Out of 76 physiotherapy lecturers at the 8 insti-tutions, the response rate to the questionnaire was 47% (35). Respondents identified that teaching EBP depends on personal experience, current literature, and availability of time, current practice patterns and CPD courses. Barriers toincluding evidence in the content of what is being taught were mainly time constraints, accessibility of journals, work-load and knowledge on how to obtain the evidence. Facilitators to including evidence in subject content were adequateresources and a well equipped library, the environment and departmental support/encouragement. Teaching EBPrequires the integration of factors such as research evidence, clinical expertise and patient values. Although the majority of respondents in the current study demonstrated a positive attitude towards teaching EBP, they reported finding it difficult to implement it in practice due to several identified barriers. It can only be to the benefit of lecturers, studentsand patients if university departments create favourable circumstances for lecturers to facilitate teaching of EBP.
The 2 × 2 Achievement Goals in Sport and Physical Activity Contexts: A Meta-Analytic Test of Context, Gender, Culture, and Socioeconomic Status Differences and Analysis of Motivations, Regulations, Affect, Effort, and Physical Activity Correlates

Approach-avoidance achievement goals are studied extensively in the context of competitive sports and physical activity, including leisure and physical education. Building upon past meta-analyses, the purpose of this quantitative review was to provide basic descriptive data, estimated means for testing of several research questions (i.e., context, gender, culture, and socioeconomic status), and meta-analyzing outcome correlates (i.e., self-determination constructs, affect, effort, and physical activity). A total of 116 studies up to 1 December 2018, met inclusion criteria. These 116 studies, totaling a sample size of 43,133 participants (M sample size = 347.85 + 359.36), from 22 countries with 92.7% of samples, are drawn from participants less than 30 years of mean age. From the 116 unique studies, nearly half (49.6%) were from a sport context and the rest from leisure-time physical activity (PA) (19.4%) and physical education (PE) (31.0%) contexts. A number of different analyses were conducted to examine our research questions. Support was found for several of our research questions: The mastery-approach goal was endorsed more than all the other goals, while sport participants endorsed the performance-approach goal more than PA and PE groups; females endorsed the mastery-avoidance goal more than males; more culturally individualistic countries endorsed the mastery-approach goal; and countries from lower socioeconomic and interdependent countries endorsed the mastery-avoidance goal than higher socioeconomic and independent countries. Concerning, the meta-analyzed correlates, most relationships were hypothesized through the performance-approach goal, and both avoidance goals appeared to be too similar in relationships with the correlates raising theoretical concerns. Overall, the mastery-approach goals had the most meaningful biased corrected effect size values (rc) with the outcome correlates, such as relative autonomy (0.47), intrinsic motivation (0.52), effort (0.40), positive affect (0.42), physical activity intent (0.38). Based on the present and past meta-analytic results, the 2 × 2 achievement goals as currently measured was questioned. Future research suggestions included fundamental questionnaire issues, the need for latent profile analysis or other more advanced statistics, and whether the 2 × 2 achievement goal framework is the most appropriate framework in physical activity contexts.

Traditional health practitioners and mental health in Kenya

The prevalence of psychiatric morbidity among rural and urban Kenyan primary care attenders has been reported to be as high as 63% (Ndetei & Muhangi, 1979; Dhapdale & Ellison, 1983; Dhapdale et al, 1989; Sebit, 1996). For its population of 32 million, Kenya has only 16 psychiatrists and 200–300 psychiatric nurses, but there are just over 2000 primary healthcare centres, staffed by general nurses and clinical officers, and the main burden for assessing and caring for people with mental disorders falls upon members of the primary care teams. However, mental disorders are poorly recognised (Dhapdale & Ellison, 1983) and inadequately treated in primary care (Muluka & Dhapdale, 1986). Moreover, Kenyan primary care workers often lack training in mental health (Dhapdale et al, 1989; see also Ndetei, this issue, p. 31).
