Collaborative caching for dissemination of videos in resource constrained environments

Video streaming on mobile devices such as PDA’s, laptop PCs, pocket PCs and cell phones is becoming increasingly popular. Video personalization is a popular strategy to provide these resource-constrained mobile devices with video content that is most relevant to the client’s request while simultaneously satisfying the client’s resource constraints. However, personalization imposes significant overheads on the origin servers as well as on the network. Our system comprises of one or more video personalization servers and several geographically distributed caches. The video personalization servers use an automatic video segmentation and video indexing scheme based on semantic video content. With the objective of optimizing cache performance, we use a novel cache replacement and multi-stage client request aggregation strategies that are specifically tailored for personalized video files. Now, we incorporate a collaborative caching mechanism for further enhancing the scalability and efficiency of disseminating personalized video content. This research reports series of experiments to study the benefits and costs of Collaborative Caching for disseminating personalized video content to resource constrained clients. We also report a series of experiments pertaining to different levels of collaboration among caches and the advantages of using Multiple Servers.

Is a haptic simulation interface more effective than computer mouse-based interface for neonatal intubation skills training?

Objective To compare the efficacy of a three-dimensional (3D) haptic interface to a two-dimensional (2D) mouse interface for a screen-based simulation (SBS) neonatal intubation (NI) training intervention. Primary hypothesis: a haptic interface is more effective than a mouse interface for SBS training intervention for NI. Secondary hypothesis: SBS training, regardless of interface, will result in improved NI performance on a neonatal airway simulator. Methods 45 participants were randomised to either a haptics or a mouse interface to complete an identical SBS training intervention for NI over a five-month period. Participants completed pre- and post-training surveys to assess demographics, experience, knowledge and attitudes. The primary outcome of participants’ NI skills performance was assessed on a neonatal manikin simulator. Skills were measured pre- and post- training by number of attempts and time to successfully intubate, and airway visualization. Results The demographics, training and experience were similar between groups. There was no difference in the improvement in skills, knowledge, attitudes or satisfaction ratings pre- and post-training between the groups. There was a significant decrease in number of attempts to intubate a neonatal airway simulator (2.89 vs 1.96, p<0.05) and improvement in the percent of subjects intubating in <30 seconds (22% vs 27%, p=0.02) from pre- to post-training in the study population overall. Conclusion Using a haptic interface did not have an advantage over a mouse interface in improving NI skills, knowledge, attitudes, or satisfaction. Overall, a SBS training intervention for NI improved skills measured on a neonatal airway simulator.
Intermittent dysfunction of prosthetic aortic valve causing acute coronary syndrome Akut koroner sendroma neden olan protez aort kapakçiğinin intermitan disfonksiyonu

Intermittent dysfunction of prosthetic aortic valve is a rare, but life-threatening condition which may be difficult to recognize. The clinical presentation, include a severe acute ischemia due to the load/perfusion mismatch or heart failure. In this article, we report a case of intermittent dysfunction of prosthetic aortic valve in a 37-year-old female case who underwent Bentall operation five years ago for bicuspid aortic valve stenosis with ascending aortic aneurysm. An electrocardiogram showed sinus tachycardia with transient ST elevation in leads aVR and V1 and ST depression in leads I, II, III, aVF and V3-V6. Physical examination and laboratory results were normal but transthoracic echocardiography showed, a flap like pannus arising from the valve near the left main ostium. Coronary angiography showed normal coronaries. The patient was scheduled for surgery and a pannus was excised. Postoperative course was uneventful.
Safety and activity of blinatumomab for older patients (pts) with relapsed/refractory (R/R) B-precursor acute lymphoblastic leukemia (ALL) in two phase 2 studies.

7043 Background: Treatment options for older pts with R/R ALL are limited. Blinatumomab is a bispecific T-cell engager (BiTE) antibody construct that directs cytotoxic T cells to CD19-expressing B cells, and is approved in the US for treatment of Ph- R/R ALL. In two phase 2 adult studies of blinatumomab (Topp MS, et al. J Clin Oncol. 2014;32:4134-40; Topp MS, et al. Lancet Oncol. 2015;16:57-66), 69% and 43%, respectively, achieved complete response (CR) or CR with partial hematologic recovery (CRh*). We report pooled data for the combined subsets of older pts ( ≥ 65 yrs). Methods: Pts with R/R B-precursor ALL received open-label blinatumomab by continuous IV infusion (4 weeks on/2 weeks off). Pts achieving CR or CRh* after two cycles could receive three consolidation cycles. Response was assessed by bone marrow aspiration. CR required blasts 1000/μL and platelets > 100,000/μL. CRh* required blasts 500/μL and platelets > 50,000/μL. Minimal residual disease (MRD) was detected by ASO-.
Comparison of labial frenectomy procedure with conventional surgical technique and diode laser

Background: An Aberrant frenum encroaches the gingival health when it is attached too closely to the gingival margin, either due to interference in the plaque control or due to a muscle pull. Such condition has to be treated by frenectomy which can be performed by scalpel, electrocautery, or with soft tissue lasers. Hence, the aim of the study is to compare the degree of postoperative pain and healing experienced by patients during frenectomy procedure with surgical scalpel and diode laser technique. Materials and Methods: A total of 20 subjects ranging from 16 to 40 years of age group with papillary or papillary penetrating frenal attachment in the maxillary anterior region were selected. Enrolled subjects were randomly divided into two groups as follows Group A (n = 10): Comprised of 10 subjects selected for conventional scalpel technique. Group B (n = 10): Comprised of 10 subjects selected for diode laser technique. Various parameters such as pain, inflammation, swelling, difficulty of procedure, and wound healing were evaluated at intervals of 1 week, 1 month, and 3rd month. Results: The results indicated patients treated with the diode laser had less postoperative pain (P < 0.0001) and required fewer analgesics (P < 0.001) as compared to patients treated with the conventional scalpel technique. Wound healing at 7th day and after 1 month for both the groups showed statistical significant difference with better outcome in Group A. However, wound healing at the end of 3 months did not show any significant difference between the groups. Conclusion: Based on current findings and clinical outcome, diode lasers provide better patient perception and an efficient and satisfactory option for procedures such as frenectomy.
Bayesian Variable Selection and Model Averaging for modelling the Probability of Default of mortgage portfolios

The subjective choice of which variables should be included in a Probability of Default (PD) model of a mortgage portfolio can significantly influence the outcome of the prediction. Bayesian Variable Selection (BVS) can be used to objectively estimate which variables should be included in the model, by assigning posterior probabilities to different variable combinations. Bayesian Model Averaging (BMA) can be used to average between these different combinations with the aim of decreasing the model specific errors. This paper investigates the improvements in prediction performance of PD models that can be achieved by implementing BVS and BMA. It is shown that BVS outperforms the benchmark variable selection criteria. It follows that implementing BMA results in an accuracy loss compared to specific BVS models, but results in more stability, robustness and overall more accurate predictions for selected model combinations.
Hip Resurfacing Versus Large-Diameter Head Total Hip Arthroplasty. A Prospective Comparative Cohort Study on Early Functional Outcomes

Objective: There is no consensus whether hip resurfacing arthroplasty (HRA) performs better than a stem-type total hip arthroplasty (THA). Therefore, the aim of this prospective comparative matched-cohort study was to answer the following questions: 1) Do gait parameters differ between HRA and THA patients at 3, 6, and 12 months after surgery? 2) Are there differences in lower extremity muscle strength at the same time points? 3) Does the selfreported outcome using validated instruments improve similarly in both groups? Methods: One experienced senior surgeon implanted either Durom HRA or CLS Spotorno THA in 34 male patients matched for anthropometric characteristics, preoperative scores and comorbidities. Preoperatively and at 3, 6, and 12 months, gait parameters, hip and knee muscle strength, clinical data and standardized outcome scores were assessed and compared between the two groups. Results: No significant group differences were found for all gait and strength variables. Passive range of motion and mean scores for the SF-36, Harris Hip Score and UCLA activity scale improved significantly over time without differences between groups. At 12 months, more HRA than THA patients were reporting groin pain on impingement testing (20% versus 0%; P<0.05). Conclusions: Excellent early outcomes were achieved by both HRA and THA in terms of score values, lower extremity muscle strength and gait parameters. No clinically relevant differences could be observed between HRA and THA patients. Groin pain after HRA remains a concern that warrants future investigation.
Original Research: Disruptive Behavior and Clinical Outcomes: Perceptions of Nurses and Physicians: Nurses, physicians, and administrators say that clinicians’ disruptive behavior has negative effects on clinical outcomes.

Overview: Providing safe, error-free care is the number-one priority of all health care professionals. Excellent outcomes have been associated with procedural efficiency, the implementation of evidence-based standards, and the use of tools designed to reduce the likelihood of medical error (such as computerized medication orders and bar-coded patient identification). But the impact of work relationships on clinical outcomes isn’t as well documented. The current survey was designed as a follow-up to a previous VHA West Coast survey that examined the prevalence and impact of physicians’ disruptive behavior on the job satisfaction and retention of nurses (see “Nurse–Physician Relationships: Impact on Nurse Satisfaction and Retention,” June 2002). Based on the findings of that survey and subsequent comments on it, the follow-up survey examined the disruptive behavior of both physicians and nurses, as well as both groups’ and administrators’ perceptions of its effects on providers and its impact on clinical outcomes. Surveys were distributed to 50 VHA hospitals across the country, and results from more than 1,500 survey participants were evaluated. Nurses were reported to have behaved disruptively almost as frequently as physicians. Most respondents perceived disruptive behavior as having negative or worsening effects, in both nurses and physicians, on stress, frustration, concentration, communication, collaboration, information transfer, and workplace relationships. Even more disturbing was the respondents’ perceptions of negative or worsening effects of disruptive behavior on adverse events, medical errors, patient safety, patient mortality, the quality of care, and patient satisfaction. These findings suggest that the consequences of disruptive behavior go far beyond nurses’ job satisfaction and morale, affecting communication and collaboration among clinicians, which may well, in turn, have a negative impact on clinical outcomes. Strategies aimed at reducing the incidence and impact of disruptive behavior are recommended.
ESTIMATION OF PROSTATIC SIZE IN DOGS USING TRANSABDOMINAL ULTRASONOGRAPHY

Transabdominal ultrasonographic evaluation was carried out to estimate prostatic size in 43 adult male dogs of four different breeds. Adult German shepherd dogs had a mean prostatic volume and weight of 26.62±1.58 cm3 and 24.33±1.65 g respectively. The mean prostatic volume and weight in adult Rottweilers were found to be 26.32±2.55 cm3 and 24.01±2.66 g respectively. Among the adult male examined by transabdominal ultrasonography in Dachshund the mean prostatic volume and weight were found to be 13.07±0.96 cm3 and 10.89±0.10 g respectively, while the prostatic volume and weight in case of adult Spitz were observed to be 11.63±0.24 cm3 and 8.71±0.25 g respectively. The study confirmed that age and body weight of the animal had a positive correlation with prostatic volume and weight.
Early or Selective Invasive Strategy in Patients with Non-ST-segment Elevation Acute Coronary Syndrome According to the Risk Factors at Presentation? An Outcome Study

Aims: Patients with acute coronary syndrome without ST segment elevation are a heterogeneous group with respect to the risk of having a major adverse cardiac event (MACE). History of diabetes mellitus (DM), chronic kidney disease (CKD) and elevated GRACE risk score are all factors defining a higher risk of MACE. We aimed to compare the outcome of patients with early vs selective invasive strategy according to the risk factors at presentation. Methodology: We enrolled 178 patients with unstable angina or non-ST elevation myocardial infarction (UA/NSTEMI), 52 (29.2%) had DM, 32 (19.7%)-CKD, defined when MDRD measured glomerular filtration rate (GFR) was <60ml/min/1.73m and 28 (15.7%) had GRACE≥140. The study had two arms: an early invasive strategy one (coronary arteriography and percutaneous coronary intervention within 24 hours after admission), Original Research Article Dimitrov et al.; CA, 2(4): 205-222, 2014; Article no. CA.2014. 4.006 206 and a selective invasive strategy arm (medical stabilization, with coronary arteriography required only in case of angina recurrence and/or evidence of inducible myocardial ischemia). Follow-up was 22.8±14 months. Results: For the whole group MACE occurred less often and the event free period was longer in the early invasive strategy group compared to selective invasive one (p=0.001). Early invasive strategy in diabetic patients, those with CKD and with GRACE ≥140 was associated with a reduced MACE rate (p=0.008, 0.016 and 0.006, respectively) and longer time to MACE occurrence compared with the selective invasive strategy. When we evaluated separately non-diabetics, patients with normal renal function and those with GRACE <140 we found no significant difference in MACE rate between the patients allocated to early invasive strategy and those assigned to selective invasive strategy. Early invasive strategy, however, showed some advantage over the selective one also in the subgroup analysis-the time to occurrence of MACE was prolonged in patients with lower risk at presentation. Conclusions: Early invasive strategy in UA/NSTEMI is associated with a reduced MACE rate and longer event-free period compared with selective invasive strategy. This benefit is clearly evident in higher risk subsets (patients with DM, CKD and GRACE ≥140).
Prevalence of Helicobacter pylori infection in residential care centers for people with intellectual disability

A recent review (5) of the prevalence of HP in asymptomatic populations from Algeria, Israel, Saudi Arabia and Turkey revealed that the prevalence is similar to findings from developing countries with a high level of infection in childhood (40-70 %), which increases with age to 85-90 %. Israel had a low prevalence among children (10 %), but a rapid increase in the second decade of life to 39 % and reaching 79 % in persons over 60 years. Our study revealed an overall prevalence rate of 75 %.
EXTENSIVE CLINICAL EXPERIENCE Primary Empty Sella

Results:Intheoverallpopulation,40of213patientshaddocumented endocrine abnormalities, specifically 31 females and nine males. Twenty-two patients (10.3% of total patients; 18 women, 10.5% of all women, with a mean age of 38.6 1.1 yr and four males, with a mean age 46.5 3.52 yr) presented with hyperprolactinemia. Global anterior hypopituitarism was confirmed in nine patients. Eight patients presented an isolated GH deficiency. One hundred thirty-eight of our patients presented a so-called partial empty sella at computed tomography scan/magnetic resonance imaging, and 75 had total PES. Conclusions: PES may be associated with variable clinical conditions ranging from mild endocrine disturbances to severe intracranial hypertension and rhinorrhea. The need for treatment of hyperprolactinemia as well as for replacement hormone therapy must be assessed in PES. Symptomatic intracranial hypertension makes cerebrospinal fluid shunting procedures necessary. (J Clin Endocrinol Metab 90: 5471–5477, 2005)
Heavy Metals Health Risk Assessment through Consumption of Baobab Leaf Cultivated in Katsina State, North West Nigeria

Vegetables play important roles in human nutrition and health. They can also contain some undesirable components that can be harmful, e.g. Pesticides and heavy metals. The objectives of the study were mainly to detect the presence of heavy metals (Cr, Cd, Fe, Ni, Mn, Pb and Zn) in sampled Baobab leaf in Katsina state Nigeria and assessed the human health risks associated with the consumption of the Baobab leaves. The content of these metals was assayed by the AAS method. The health risk to the local inhabitants was evaluated by estimating daily heavy metal intake and computing the Incremental Lifetime Cancer Risk (ILCR) and the Target Hazard Quotient (THQ) for cancer and non-cancer risks. The results were compared with the safety standards established by the WHO/FAO and USEPA. With the exception of the heavy metal Pb (0.526-0.981) the mean concentration (mg/kg) range values of Cr (0.116-0.352), Cd (0.041-0.054), Fe (1.016-1.951) and Zn (0.940-1.229) in the samples were generally lower than the USEPA, WHO/FAO maximum permissive limits. The risk level of Target Hazard Quotient (THQ < 1) was observed for all the evaluated heavy metals for both adults and children. The THQ for the samples was in the decreasing order Zn>Fe>Pb>Cr>Cd, for all the baobab leaf samples respectively. All the studied samples showed the risk level (HI < 1). ILCR for Cd violated the threshold risk limit (>10−4) and ILCR for Pb reached the moderate risk limit (>10−3) for cancer in all the studied samples in adults, While in children ILCR for Pb in samples from Dabai and Daura have reached the moderate risk limit (>10−3), while the ILCR for Pb in rest of the samples and ILCR for Cd of all the samples are beyond the moderate risk level (>10−2). The consumption of the Baobab leaf sample may contribute to the population cancer burden.
Teaching and learning supervision by school management, attitude of teachers and competency of teaching

This study aimed to identify teaching and learning supervision by school management, the attitude of teachers and competency of the teaching of secondary schools teachers in Kubang Pasu, Kedah. Specifically, the study focused on the implementation of teaching and learning supervision, attitude of teachers and competency of teachers and differences in attitudes towards demographic teaching experience. The sample involved were 82 teachers. The instrument used was a set of questionnaire containing 66 items on teaching and learning supervisory dimension attitudes, and competency of teaching. Data were analyzed using descriptive statistics and statistical inference, mean, standard deviation, ANOVA and Pearson correlation. The results showed that the level of teaching and learning supervision in schools as a whole is high. However, there was no significant relationship between teaching and learning supervision with an attitude and competency of teaching. In addition, the findings also indicated that there is a difference in attitude with teaching experience. Overall results showed a positive relationship between moderate and weak teaching and learning supervision with an attitude and competency of teaching. In conclusion, if the implementation teaching and learning supervision are high then the attitude and competency of teaching can be improved.
Perfil sóciodemográfico de mães atendidas em um serviço de triagem auditiva neonatal Sociodemographic profile of mothers asmitted to a service of newborn hearing sccreening Perfil sociodemográfico de madres en un servicio de screening auditivo recién nacidos

Purpose: To describe the sociodemographic profile of mothers of newborns who participated in the Newborn Hearing Screening (NHS), at a University Hospital in Rio Grande do Sul, Brazil, as well as to identify the mothers’ knowledge about the NHS. Method: The study was achieved at the NHS service of the mentioned hospital, from April 2011 to December 2011. The number of mothers who answered prenatally the questionnaire of demographic investigation was 1022. They answered questions regarding their knowledge about NHS. Results: The mothers’ average age was 26 years old. In relation to education, 32.19 % completed high school, 27.79 % presented incomplete elementary school and 3.03 % completed graduation degree. About occupation, 52.05% referred being house wives. About marital status, 57.24 % of the mothers were single, 30.57 % were married, 8.40 % presented common-law marriage and 3.72 % were widows or divorced; 63.57% of mothers did monthly prenatal exams and 1.86 % did not. From these mothers, 54.21 % have more than one child, and from them, 39.8 performed NHS with their other children; 47.85 % obtained knowledge about NHS after the last child’s birth, 33.86 % were informed by the Pediatrician and 34.24% by the Nurses. Conclusion: The main sociodemographic characteristics of this study were: young adult mothers, with complete high school, house wives, single, and with more than one child. Most of them performed prenatal, but the information about NHS was given to them at the hospital, right after their children were born. The identification of these characteristics is important to direct the actions by the Speech Therapy in Primary Health Care, improving the structuring of the Hearing Health Program in the studied region.
The impact of capital structure on the performance of microfinance institutions

Article history: Received: September 8 2019 Received in revised format: September 22 2019 Accepted: October 6, 2019 Available online: October 6, 2019 In this paper, the microfinance services are evaluated in the context of small-scale businesses in Jordan. The aim of this study is to emphasize on the importance of factors related to micro-finance as it helps in enhancing the firm’s performance. This study utilizes a quantitative approach to conduct a research on approximately 308 small-scale businesses. The study employs a method of confirmatory component analysis (CFA) held by applied Structure Equation Modelling (SEM) to achieve the research objective. The results demonstrate that performance was significantly associated with various micro-finance services such as training for managers, training skills, and loan size. In particular, micro-finance programs should be considered by small entrepreneurs, microfinance institutions, and policy makers. Thus, the contribution of this work is the incorporation of micro-finance factors on SMEs performance. Managers of the SMEs will find guidance about which micro-finance factors is the most important for them to be considered in their roles and for improving SMEs performance. © 2020 by the authors; licensee Growing Science, Canada
