Assessment of the Effect of Implant Recipient Site ́s Bone Density on Initial Implant Stability in the Anterior Mandibular Region

Objective: The aim of this study was to assess the correlation between the bone density of the potential implant sites and the initial implant stability in the anterior mandibular region. Subjects and Methods: A total of 54 implants were placed in the anterior mandibular region of 27 patients. The preoperative bone densities of the implant recipient sites were evaluated using Cone Beam Computed Tomography [CBCT] and the initial implant stability using Resonance Frequency Analysis [RFA] measured as implant stability quotient values [Osstell, ISQ]. Results: The mean bone density among all implant sites was 830.4± 141.1 HU (range: 546.7 to 1265.7) and the mean ISQ values was 67.9± 6.3 (range: 55 to 79). There was a statistically significant correlation between the bone density of the recipient implant sites and the ISQ values measured immediately after implant placement Conclusion: The results of this study demonstrated a significant correlation between preoperative bone densities of the implant recipient sites in the anterior mandibular region as evaluated using cone beam computed tomography and the initial implant stability measured using resonance frequency analysis.

Impact evaluation on health: three case studies for Colombia

The present work uses impact evaluation tools in health economics to analyze three different issues in Colombia. The first issue is how losing health insurance for young adults affects medical service usage and health outcomes. Results show that losing health insurance when turning 18 years old increases visits to the ED, reduces preventive care visits with a physician, and increases the usage of private medical services (out-of-pocket) for young adults. For the second issue, we measure how exposure to high levels of air pollution affects children´s health, looking at children under five years old attending public kindergartens in Bogota; results show evidence that mothers who are exposed to higher levels of CO and O3 during the second and third trimesters of pregnancy (in-utero), have a higher probability of their babies being born with a low birth weight. Furthermore, the mother being exposed to high levels of O3 during the second trimester increases the probability of the child being diagnosed with a lung-related disease. These results imply that air pollution affects young children’s health, which may have an impact on future outcomes and human capital formation. The third issue analyzes how an economic activity boom has unintended consequences on sexually transmitted infections. Results show how gold mining activities increased the incidence of STIs such as syphilis and gonorrhea in three and six cases per 100,000 inhabitants respectively in municipalities with gold mining.
Spatio-Temporal Patterns in Portuguese Regional Fertility Rates: A Bayesian Approach for Spatial Clustering of Curves

Abstract It is important for demographic analyses and policy-making to obtain accurate models of spatial diffusion, so that policy experiments can reflect endogenous spatial spillovers appropriately. Likewise, it is important to obtain accurate estimates and forecasts of demographic variables such as age-specific fertility rates, by regions and over time, as well as the uncertainty associated with such estimation. Here, we consider Bayesian hierarchical models with separable spatio-temporal dependence structure that can be estimated by borrowing strength from neighbouring regions and all years. Further, we do not consider the adjacency structure as a given, but rather as an object of inference. For this purpose, we use the local similarity of temporal patterns by developing a spatial clustering model based on Bayesian nonparametric smoothing techniques. The Bayesian inference provides the uncertainty associated with the clustering configurations that is typically lacking in classical analyses of large data sets in which a unique clustering representation can be insufficient. The proposed model is applied to 16-year data on age-specific fertility rates observed over 28 regions in Portugal, and provides statistical inference on the number of clusters, and local scaling and shrinkage levels. The corresponding central clustering configuration is able to capture spatial diffusion that has key demographic interpretations. Importantly, the exercise aids identification of peripheral regions with poor demographic prospects and development of regional policy for such places.
Institutional review of glial tumors treated with chemotherapy: the first description of PCV-related pseudoprogression.

Background Pseudoprogression refers to areas of enhancement on MRI postadjuvant chemoradiation that arise as a result of treatment-related effects. Pseudoprogression has been well described with temozolomide-based chemoradiation but has not been studied in the setting of procarbazine, lomustine, and vincristine (PCV) chemotherapy. We reviewed patients treated with PCV to investigate the occurrence of pseudoprogression. Methods Adults diagnosed with World Health Organization grade II or III gliomas between 2010 and 2015 and treated with PCV or temozolomide were identified. Patient, tumor, treatment, and MRI data were retrospectively collected and analyzed. Pseudoprogression was defined as new enhancement seen on MRI within 6 months of completion of adjuvant radiotherapy or concurrent chemoradiation, which improved or remained stable on subsequent scans without therapeutic intervention. If MRI showed areas of new enhancement outside the 6-month post-treatment window, which resolved or remained stable without treatment, or in patients who did not receive adjuvant treatment, it was referred to as "atypical pseudoprogression. " Results Fifty-seven patients were identified. Nine (16%) patients were identified as having pseudoprogression on MRI. Two (4%) of these patients were treated with PCV and 7 (12%) were treated with temozolomide. Seventeen (30%) patients had atypical pseudoprogression: 8 (14%) treated with temozolomide, 8 (14%) treated with PCV, and 1 (2%) treated with both types of chemotherapy. Conclusions We describe the first 2 cases of PCV-related pseudoprogression and 17 cases of atypical pseudoprogression. As the re-emergence of adjuvant PCV occurs in clinical practice, the occurrence of classical and atypical pseudoprogression could have a significant impact on clinical decision making.
An Unquantified Uncertainty Visualization Design Space During the Opioid Crisis

We propose a visualization design space for representing unquantified uncertainty in percent composition drug checking test results using pie and cake charts during the opioid crisis. The design space generates alternatives for use in a visual drug report design study that may improve decision-making concerning illicit drug use. Currently, communication of drug checking test results does not capture the uncertainty in drug checking tests, leading to poor and potentially harmful decisions. The design alternatives generated by the design space aim to empower people who use drugs with drug sample information and facilitate harm reduction efforts. Our visualizations may apply to other drug checking services and to scenarios where uncertainty visualization researchers wish to notify end users of the presence of unquantified uncertainty in safety-critical decision-making contexts like those found during the opioid crisis.
The prevalence of ADHD in children with enuresis: Comparison between a tertiary and non‐tertiary care sample

Objective: The main aim of the current study was to determine reliable comorbidity rates of ADHD for enuretic children admitted either to non‐tertiary care or to a specialized paediatric clinic, i.e. tertiary care, since previous research has failed to incorporate a possible setting effect in this comorbidity; and to use a multi‐method multi‐informant assessment of ADHD. Material and methods: Eighty children, aged between 6 and 12 y, admitted to non‐tertiary care with enuresis and 120 children referred to tertiary care were screened for the presence of ADHD using a multi‐method (diagnostic interview, questionnaires) multi‐informant (parents, teachers) assessment. Results: Enuretic children from the tertiary care sample have a 3.4 times increased chance of having comorbid ADHD when compared to children with enuresis admitted to non‐tertiary care, corresponding to a prevalence rate of 28% and 10%, respectively. Overall, the tertiary care sample was older, showed more daytime incontinence and revealed an increasing prevalence of ADHD with older age when compared with the non‐tertiary care group.
Knowledge And Practice On Childhood Diarrhea Among Mothers Having Children Under Five Years Of Age In Madhuban, Sunsari, Nepal

Rotavirus is a leading cause of acute diarrhea and causes about 40% of hospitalization for diarrhea in children under five years of age. Hence the study aims to assess the mothers’ knowledge and practice regarding childhood diarrhea in Madhuban , Sunasari, Nepal. The descriptive cross-sectional study design was used for the study. A total of 117 respondents were selected using simple random sampling method’s random number table. Data were collected using face to face interview method through a semi-structured questionnaire and analyzed using SPSS 11.5. The finding revealed that 93.2% of the respondents were literate. All of the respondents had knowledge of giving ORS when their child suffered from diarrhea. The entire respondent used to wash hands before preparation of ORS and after assisting the bowl movement washing of their children. Majority of them (92.5%) said that they gave more amount of fluid while their child was suffering from diarrhea. About 68.4% of respondents had ORS at their home. Education had a higher impact on the mother about the diarrhea management of their children. The study showed that the use of ORS is in increasing trend, overcoming the use of saltsugar solution. But on the other hand low percentage of mothers had knowledge that vitamin A prevents children from diarrhea. Therefore, at the community level, mother and child who are in vulnerable condition should be identified and proper education and advice should be given on the importance of Vitamin A, ORS and zinc tablets for the management of diarrhea.
The Geo-Seas seismic data viewer: a tool to facilitate control of data access

Data transparency could be used as a metaphor to describe how data owners can give controlled access to their data to end users. In a scientific environment and focusing on seismic data, this is a very delicate activity that needs to consider the desire for data owners to position themselves in the research community, possible legal issues and the commercial incomes that data could provide. In this perspective, this work focuses on the possibility of having various levels of access to data so that its opacity can be progressively removed according to the contractual status with the end user. Within the EU FP7 Geo-Seas project, an interactive web-based seismic data viewer tool has been developed in order to provide these features. End users work within secured shells contained in the viewer without downloading any data. This relieves the concerns of data providers of losing control of their data, fosters their collaborative attitude and ultimately increases the availability of data within the community.
A New Perspective to Measuring Employee Growth: Developing a Successful Aging at Work Scale

The aging of the world’s population has become a grand societal challenge, which requires an urgent response from researchers, professionals, and the wider society. One way to respond to this challenge is by supporting individuals in sustaining longer and healthier working lives, that is, age successfully. Although the advantages of promoting and enabling successful aging at work have been widely acknowledged, no single instrument for measuring this construct has been published so far. We develop and test in three consecutive samples a two-dimensional successful aging at work scale. This novel instrument is rooted conceptually in the most recent theoretical developments and is applicable to a variety of work settings and groups of workers. It can be used by both employees and employers for the purposes of individual and organizational development. We also propose directions for future research.
A prospective study of serum concentrations of leptin, homocysteine and insulin resistance in children with steroid-sensitive nephrotic syndrome

Aim: To measure serum leptin, homocysteine concentrations and insulin resistance in active and remission stages of children with nephrotic syndrome (NS) and to investigate their role in NS pathogenesis. Methods: A total of 70 children were included in the study, 40 patients who had been diagnosed with NS and 30 healthy patients were control. Changes in plasma concentration of the serum homocysteine, leptin, and insulin were measured and compared with the other parameters in the groups. Results: Serum leptin concentrations in active phase were lower than the remission phase (1.48 ± 0.09 ng/dl, 1.84 ± 1.64 ng/ml, p<0.05). Also, serum homocysteine concentrations in NS group during the active phase were lower than the remission phase and the control group (6.45±2.54 ng/dl, 9.35±2.99 ng/ml, 7.76± 1.97 ng/ml, p<0.05). The serum fasting insulin concentrations and homeostatic model assessment for insulin resistance (HOMA-IR) values of remission phase were significantly higher than those of active phase (p<0.05). A positive relationship was found between the homocysteine concentrations and the body mass index of the patient; whereas, a negative relationship was detected between erythrocyte sedimentation rate (ESR), and the LDL-cholesterol concentrations (p<0.05). ESR was found as the only factor associated with lower concentrations of homocysteine during the active phase (r:-0.592, p<0.05). Conclusion: In this study, we demonstrated that serum leptin and homocysteine concentrations decreased in active phase and increased in remission phase in children with NS. Insulin resistance could also develop as a result of steroid use in a short period of time in these patients.
Awareness of Natural and Man-Made Radiation and Their Effects among Patients Awaiting Radiological Investigations

Individuals undergoing radiological investigations are exposed to natural and man-made radiation which could be ionizing or non-ionizing. This study aimed at assessing the knowledge of radiation and practice of radiation protection measures among patients awaiting radiological investigations at a teaching hospital in Southwest Nigeria. Consenting patients awaiting investigations at the radiology department of LAUTECH teaching hospital were enrolled for this study. Semi-structured interviewer-administered questionnaire were used and knowledge scoring was done. The data were analyzed using Statistical Package for Social Scientists (SPSS) version 22 and p< 0.05 were considered statistically significant. The mean knowledge of radiation score among the 200 patients studied was 55.8%±20.8. Participants with high education had significantly higher score (62.46%±15.07) than those with low and no formal education (34.79%±22.38) p= 0.001. Participants who practiced personal protective measures had higher scores than those that do not p= 0.001. However, there was no statistically significant difference in the knowledge scores between the males and females (55.59%±20.41vs 56.14%±21.35) p>0.05. This study showed that knowledge about radiation helps in adopting a lifestyle that protects from radiation but the knowledge of participants about radiation appears to be shallow. Patients were not aware of the type of radiological investigation they undergo and the associated radiation risk. It is strongly recommended that patient should be well informed about the radiological investigations they undergo.
A Performance Assessment of Flood-Damaged Shearwalls

Flood events affect more people than any other form of natural disaster. Flooded structures are partially submerged and then re-dried, which leads to swelling and shrinking over an arbitrary wall height. One repair scheme is to remove the interior cladding (drywall), dry the wood system, and re-install new drywall. This investigation was conducted to evaluate the effects of long-term water exposure on the mechanical properties of oriented strand board (OSB) sheathing and the impact of those changes on the capacity of light-frame shearwalls. OSB was submerged for up to seven days, air-dried and then tested for embedment strength, shear strength through the thickness, and shear modulus. Nine walls were built for the test program. Three were tested at ambient conditions and monotonically loaded in shear to establish the displacement criteria for the quasi-static methods; three walls were tested at ambient conditions (control walls) using a quasistatic loading protocol; and three were submerged in 1 m of water for seven days, re-dried, and then tested using the same quasi-static protocol as the control walls. The results from the OSB material tests showed that most of the material property degradation occurred in the first 48 hr of submersion, for example, the embedment strength was reduced by almost 40 percent after 48 hr and showed no further reduction even with 120 hr of additional soaking. The shearwall test results did not follow the materials’ results -the quasi-static shearwall tests showed that water submersion did not reduce shearwall capacity, the energy absorption of the wall, or change the yield mode. However, shearwall stiffness was reduced, apparently the result of reduced embedment stiffness of the OSB sheathing.
The Correlation between Giving Health Teaching Regarding Vulvovaginal Infectivity and Self Report of Symptoms with Faculty of Nursing , Kafrelsheikh University Students

Background: Vulvovaginitis is an inflammation of external genitalia and it is standard as a major public medical problem that causes several problems for women at all ages. Aim: Was to assess the correlation between giving health teaching regarding vulvovaginal infectivity and self report of symptoms with Faculty of Nursing, Kafrelsheikh University students. Design: Descriptivecorrelational design was used. Sample: A total of 700 adolescent girls were assigned from the Faculty of Nursing, Kafrelsheikh University, Egypt. Tools: Two tools were developed by the researcher 1.Self administered questionnaire sheet to collect data including demographic information about students, knowledge assessment questionnaire about vulvovaginal infectivity, assessment questionnaire about menstrual hygienic care and evaluating score for students' knowledge, 2. Self reporting tool that included counting the number of students complains regarding their self report of symptoms of vulvovaginal infectivity. Results: The mean age of students under study was17-21 years, their mean age was 18.380±0.8540years; 7.20% of them reported about symptoms of vulvovaginal infection after teaching session, and 100.0% of them had unsatisfactory level of knowledge score related to vulvovaginal infection during the first time of assessment(before teaching session) but after the teaching session was carried out the vast majority of students had satisfactory level of knowledge score during second , third assessment respectively. There was statistical significant relation between the level of knowledge (satisfactory or unsatisfactory level) and self report of vulvovaginal infection symptoms during the second assessment (p= 0.010). Conclusion: There was statistical significance between the level of knowledge (satisfactory level) and self report symptoms of vulvovaginal infection during the second evaluation, cheesy white vaginal discharge and itching in the external genitalia were the most ordinary complains amid adolescent students who made self report. Recommendations: The present study suggested raising awareness among adolescent young girls principally at those early years in relation to their level of knowledge about vulvovaginal & how to report any deviation.
Relationship between dependence to mobile phone with loneliness and social support in University students

Background : The rapid development of communication and mobile use has generated discussions about changing people's life and their dependence on cell phones. Dependence to mobile phone creates a sense of loneliness and unsuitable social support. This study aimed to determine the relationship between cell phone use and loneliness and social support scores in Tehran University of Medical Sciences’ students in 2002. Methods: This descriptive - analytical study was conducted on 405 students in Tehran University of Medical Sciences. Samples were selected by stratified sampling method. Instruments for collecting the data were the standardized questionnaires of Mobile phone Addiction Index (MPAI) and the third edition of Loneliness Scale UCLA and social support, along with demographic questions. The data were analyzed using SPSS version 16, and the ANOVA, chi-square and Pearson correlation co-efficient tests. Results: The mean for mobile phone dependence, loneliness and social support scores were: 83/41 (moderate), 53/16 (moderate) and 93/30 (borderline, mild to moderate), respectively. A significant correlation was observed between the dependence to mobile phone with loneliness and social support scores (respectively r= - .32, r= - .36, p=.001). Moderate and sever dependency upon mobile phone were higher in female students (p=.046), under 25 years old students (p=.001, p=.04) and medical and health science students. Conclusion: Average of dependence to cell phone, loneliness and social support is not appropriate in these students and excessive use of mobile phone is associated to feeling loneliness and social support. Depending to mobile phone is related to age, sex and health and medical colleges’ students. Therefore designing effective interventions and education of correct use of mobile phones are recommended.
Size and plasticity effects in the compression zirconia micropillars

The micropillar compression technique has shown the potential for activating the brittle-to-ductile transition in ceramic monocrystals when testing reduced volumes. In this work, the role of size is studied by comparing the mechanical response of polycrystalline tetragonal zirconia micropillars and macroscopic specimens under compression. In micropillars, the absence of the natural defect population typical of bulk zirconia increases considerably the strength, allowing the activation of plastic deformation mechanisms and their study, showing in this way that the brittle-to-ductile transition is not limited to ceramic monocrystals only. The main mechanism of plastic deformation is transformation-induced plasticity, which is shown to be size dependent. The deformation behavior is studied in detail by loading-unloading tests at constant and increasing peak stresses, while the microstructure evolution is revealed by FIB cross-sections, TEM and STEM observations performed on lamellas extracted from pillars retrieved before failure. Finally, a failure mechanism is proposed, based on the damage induced by phase transformation.
