The Assessment of the Acceptability of Behavior Management Techniques for Pediatric Patients by Their Mothers Referred to a Pediatric Dental Clinic in Tehran

The use of behavior management techniques for the treatment of children who are uncooperative with a dentist is inevitable. Behavior management techniques are the methods that the dental health team could effectively treat the child and inspires a constructive dental attitude. Objective: Determining the acceptability of behavior management techniques by mothers referred to a pediatric dental clinic in Tehran (2017). Materials and Methods: This cross-sectional descriptive study was conducted in a pediatric dental clinic in Tehran. A film, including 4 different behavior management techniques such as general anesthesia(GA), parents’ separation(PS), Tell-Do-Show and voice control(VC) was produced. Before showing each method, a brief explanation of the characteristics and purposes of methods was given by a pediatric dentist in the film. A total of 50 mothers, referred to this private dental clinic, completed a questionnaire after observing any method in this film. The data were analyzed using t-test and Chi-square Results: 56% of the children were boys and 44% were girls, and they were in the age group of 3 to 10 years old, and children are ranked from first to fifth in the family. Mothers with a primary to postgraduate education were between the ages of 23-50 and had up to 5 kids. The acceptance of Tell-Do-Show by mothers was 100%, Voice Control was 92%, separating the child from parents was 50%, and General Anesthesia was 30%. There was a significant correlation between acceptance of voice control method with child's order, child's age and the number of children in a family, and also between the acceptance of general anesthesia by mothers with mother's education level and child's order (p <0.05). Conclusion: According to the findings, Tell-Do-Show method was the most common method which was accepted by mothers, and general anesthesia was the least accepted method by the mothers.
Hypofractionated Proton Therapy in Early Prostate Cancer: Results of a Phase I/II Trial at Loma Linda University.

Purpose To determine whether a hypofractionated proton therapy regimen will control early-stage disease and maintain low rates of side effects similar to results obtained using standard-fraction proton therapy at our institution. Materials and Methods A cohort of 146 patients with low-risk prostate cancer according to National Comprehensive Cancer Network guidelines (Gleason score <7, prostate-specific antigen [PSA] <10, tumor stage of T1-T2a) received 60 Gy (cobalt Gy equivalent) of proton therapy (20 fractions of 3.0 Gy per fraction) in 4 weeks, a dose biologically equivalent to standard fractionation (44-45 fractions of 1.8 Gy to a total of 79.2 to 81 Gy in 0 weeks). Patients were evaluated at least weekly during treatment, at which time documentation of treatment tolerance and acute reactions was obtained. Follow-up visits were conducted every 3 months for the first 1 years, every 6 months for the next 3 years, then annually. Follow-up visits consisted of history and physical examination, PSA measurements, and evaluation of toxicity. Results The median follow-up time was 42 months (range, 3-96 months). Acute grade 2 urinary toxicity occurred in 16% (20/120) of the patients; acute grade 2 or higher gastrointestinal toxicity was seen in 1.7% (2/120). At 9 months, 1 patient had late grade 3 urinary toxicity, which resolved by 12 months; no grade 3 gastrointestinal toxicities occurred. The 3-year biochemical survival rate was 99.3% (144/145). The median time to PSA nadir was 30 months. Conclusion Hypofractionated proton therapy of 60 Gy in 20 fractions was safe and effective for patients with low-risk prostate cancer.
Controversies of radiation therapy omission in elderly women with early stage invasive breast cancer

Early stage invasive breast cancer is a disease that is prevalent in the elderly population. Data regarding radiation omission for elderly population is based on patients’ age. Given the increased life expectancy, data on individualizing treatment decisions based on multiple tumor and patient related factors other than age only is emerging. This review aims to analyze published data to provide clinicians with a general oversight on approaching this question.
Changes in Intraoperative and Postoperative Neural Response Telemetry in Cochlear Implant Users

Introduction: The cochlear implant directly stimulates the auditory nerve in deaf patients. Neural Response Telemetry (NRT) is used to record the response of the auditory nerve through thefeedback of the electrical signal. NRT does not need behavioral responses from very young children for thresholds and comfort levels. The status of the cochlear nerve activation with NRT was reviewed through intraoperative and postoperative neural responses. Aim of the work: To detect any changes in intraoperative and postoperative neural response telemetry in cochlear implant users. Patients and Methods:Thirty patients were implanted with a MED-EL device, Sonata II (Med-El, Innsbruck, Austria) at Sohag University hospital. Electrodes 2, 4, 6, 8, 9, 10, 11 and 12 were monitored intraoperatively. One month after surgery, the neural responses were investigated using the same electrodes as during the intraoperative procedures. The corresponding electrodes werethen checked again after another 3 months.Phase duration 30µs, begin by amplitude 200cu increasing in steps each 100cu till get response or reaching maximum level 1200cu (intraoperative) or reached the uncomfortable level of the child (postoperative). Threshold of the neuronal response is calculated using linear equation function. Results:There is significant improvement in thresholdsof NRTresponse postoperatively which was high intraoperatively. NRT threshold increase in postoperative follow up in comparison with first postoperative measurement but this increase is not statistically significant. Conclusion: Absence of NRT response in some electrodes intraoperative does not mean that electrode must be out of function or outside the cochlea.
RFID Authentication: New Techniques and Privacy Implications

Radio-Frequency IDentification (RFID) technology provides an inexpensive means to identify physical objects. The wide proliferation of RFID devices, or tags, in our everyday life, such as electronic identity documents and contactless transportation tickets, raises both security and privacy concerns. On the one hand, RFID tag identification does not guarantee authenticity: the identifiers stored in RFID tags used for object identification can be copied, creating, in fact, indistinguishable clones of the original tags/objects. RFID tag authentication solutions provide a means to verify claimed identities. However, a number of challenges must be faced when designing such solutions, in particular related to constrained (in size, power, cost) tags. On the other hand, RFID technology raises several privacy concerns regarding both clandestine tracking of final consumers and disclosure of confidential information by business partners employing RFID systems. These concerns may dramatically limit the deployment of RFID technology. In this thesis, we first explore tag authentication and clone detection techniques suitable for constrained RFID tags. Then, we investigate the privacy implications of the explored techniques. In the first part of this thesis, we propose and evaluate tag authentication and clone detection techniques based on physical-layer fingerprinting and tracing information. The proposed physical-layer techniques aim at uniquely distinguishing RFID tags through their physical-layer fingerprints, i.e., using characteristics that tags show in the transmitted RF signals. Differently, the proposed technique based on tracing information aims at detecting cloned RFID tags by analyzing tag-related information collected by the different entities employing an RFID system. We find that our techniques provide reliable tag authentication / clone detection suitable for constrained RFID tags. In the second part of this thesis, we investigate the privacy implications of the proposed tag authentication / clone detection techniques. We first explore the practicality of tracking people carrying RFID tags by means of the physical-layer fingerprints of their tags. We demonstrate that tracking people carrying RFID tags is feasible and practical, even in the presence of upper-layer protection measures (e.g., encryption). Then, we propose and evaluate a protocol that provides information privacy for clone detection based on tracing information. We show that our protocol allows a set of entities to collaboratively detect clones without disclosing information on their collected tag-related information or their relationships.
Impact of smoking and second hand smoke on cardiovascular health

Dr. Edgardo Sandoya Cardiólogo del Servicio de Cardiología, Asociación Española 1a de Socorros Mutuos. CIET, Centro para la Investigación de la Epidemia de Tabaquismo. Montevideo. RESumEn: Arch med Interna 2011 XXXIII(2): 29-38 El tabaquismo constituye la principal causa evitable de muerte y enfermedad. Quienes fuman tienen mayor incidencia de enfermedades cardiovasculares debido a que el cigarrillo favorece el desarrollo de la ateroesclerosis y altera la provisión de oxígeno a los tejidos. Estos fenómenos se traducen en mayor incidencia de infarto agudo de miocardio, muerte súbita, angina de pecho, accidente cerebrovascular, aneurisma de aorta y arteriopatía en los fumadores. Entre quienes fuman también hay mayor incidencia de infarto luego de una angioplastia, mayor mortalidad del accidente cerebrovascular, mayor expansión del aneurisma aórtico y mayor tasa de falla del bypass fémoro-poplíteo. La exposición pasiva al humo de tabaco de segunda mano aumenta el riesgo de enfermedad coronaria, accidente cerebrovascular e infarto de miocardio. El estrés oxidativo, la estimulación adrenérgica, la disfunción autonómica y el aumento de monóxido de carbono que ocurren al exponerse al humo de segunda mano pueden desencadenar, en tan sólo 30 minutos, un evento coronario agudo. El Convenio marco de Control del Tabaco de OmS es la herramienta de Salud Pública que enfrenta la epidemia de tabaquismo; estas acciones deben ser complementadas por los clínicos, brindando los cuidados que ayuden a sus pacientes fumadores a controlar la adicción para de esa forma reducir su riesgo cardiovascular.
Obstruction-Aware Bluetooth Low Energy Indoor Positioning

Bluetooth low energy (BLE) technology is demonstrating significant potential in providing accurate and reliable positioning indoors. However, wireless signals such as Bluetooth, tend to be affected by an obstruction, thus creating a non-line-of-sight (NLOS) environment. This paper proposes a statistical technique for improving the accuracy of indoor positioning using BLE technology through detecting obstructions and compensating for signal degradation caused. Several experiments are conducted to observe the obstruction effect on the signal stability, computed in this paper using standard deviation. Results show a lower standard deviation for an NLOS environment. A threshold is suggested at 2.6 dBm to detect a line-of-sight (LOS) environment. The detection accuracy of this threshold is 76.25%; thus, in most cases, the technique will be able to differentiate an LOS from an NLOS environment. Using this technique, positioning in NLOS environments show an average of 1.13 metres improvement compared to positioning without using the technique.
Pixel Analysis Technique for Image Denoising

The image de-noising is the technique which is applied to de-noise the image. The noise is the extra pixels which are added on the image to reduce image quality. In the previous times, various techniques have been proposed which remove noisy pixels from the image. In the base paper, technique of sparse matrix technique proposed which divide the whole image into small matrixes and similarity of each matrix is calculated. The matrix which is maximum dissimilarity is removed from the image. This leads to remove noisy pixels from the image and increase image quality in terms of various parameters. In this work, technique of probability is proposed which calculate probability of each pixel and pixels which has maximum probability to be noisy is remove the image. The proposed technique is implemented in MATLAB and compare with existing technique of sparse matrix. It is been analyzed that proposed technique performs well in terms of various matrix.
Study of Galvanic Skin Response in Patients of Moderate Depression

With the rapid development the society the persons are having feelings o f sadness, loss, anger, or frustrations which interfere with everyday life for an extended period o f time resulting in the appearance o f various psychological problems, out o f which depression is most common having a prevalance o f 15.1% in India. Severe depression causes various physiological abnormalities leading to various co-morbid conditions. But there is very little literature available about moderate depression; hence the present study is designed to study the effect o f moderate depression on the autonomic system by galvanic skin response and cold pressor test. We studied 40 male patients (to avoid gender difference) o f moderate depression and 40 normal subjects of* same age group at rest in supine position (to avoid posture effect). Galvanic skin response was recorded and compared between these two groups. Comparison of*these two groups showed that GSR is not significantly different in moderate depression patients than that from the normal subjects. Though the major depression is associated with various co- morbid conditions but moderate depression hardly affects the autonomic system. Hence it is better to diagnose and treat the depression at moderate state.

A review of effective interventions for reducing and controlling obesity in primary school children

Objectives: The prevalence of obesity has been doubled among children over the past 10 years, which will result in an obese population and its complications in near future. This situation can impose great costs on the health system and community for treating those obese people. The purpose of this review is to examine the effective strategies for reducing and controlling obesity in primary school students. Methods: This review was conducted in August and September 2017. Our goal was to review the related articles in the authorized databases, including Scientific Information Center (SIC), Scholar Google, Scopus, and PubMed, from 2000 onward, by two researchers, considering language constraint (only English articles with full text were accepted). Out of 104,658 articles, 15 articles were excluded due to the lack of full text, and finally 25 articles were selected. Results: The results of the existing studies showed that through involving parents, schools officials and continuous supporting measures like prohibition of long-term food advertising in television programs, all three educational, nutritional and physical activity interventions can help in controlling and reducing obesity. Conclusions: To succeed in reducing and controlling obesity among students, especially primary school ones, the approaches and interventions should be implemented in three levels: home, school, and community.
Hyaluronic Acid as an Alternative to Autologous Human Serum Eye Drops: Initial Clinical Results with High-Molecular-Weight Hyaluronic Acid Eye Drops

Introduction: Autologous serum eye drops (ASED) are used in the treatment of most severe stages of dry eye. Once introduced, it is currently considered impossible to return to other lubricating eye drops or other commercially available therapeutic regimen. Materials and Methods: In a randomized study, non-preserved high-molecular-weight hyaluronic acid eye drops were offered as an alternative to 11 patients using autologous serum treatment for at least 3 months. The control group (n = 5) continued their treatment with ASED. The verum group (n = 6) used very-high-molecular-weight hyaluronic eye drops (Comfort Shield®) instead of the ASED. Results: From four of initially six patients in the verum group that finished the study, 2 (50%) preferred to stay with the very-high-molecular-weight hyaluronic acid eye drops beyond the trial period, the other two returned to the earlier therapy with ASED. The control group continued their treatment as before and finished the study after 8 weeks. Conclusion: For the first time, artificial eye drops, i.e., high-molecular-weight hyaluronic acid eye drops, offered an acceptable alternative to ASED. Some patients perceived these drops as even better than the patient’s own serum. This is the first evidence that optimization of the molecular structure of hyaluronic acid can be used to create eye drops that are perceived to be better than other tested tear substitutes and even patients’ own serum. This offers a new treatment perspective for patients with very severe dry eye disease.
Quantitative Brain Morphometry of Portable Low-Field-Strength MRI Using Super-Resolution Machine Learning.

Background Portable, low-field-strength (0.064-T) MRI has the potential to transform neuroimaging but is limited by low spatial resolution and low signal-to-noise ratio. Purpose To implement a machine learning super-resolution algorithm that synthesizes higher spatial resolution images (1-mm isotropic) from lower resolution T1-weighted and T2-weighted portable brain MRI scans, making them amenable to automated quantitative morphometry. Materials and Methods An external high-field-strength MRI data set (1-mm isotropic scans from the Open Access Series of Imaging Studies data set) and segmentations for 39 regions of interest (ROIs) in the brain were used to train a super-resolution convolutional neural network (CNN). Secondary analysis of an internal test set of 24 paired low- and high-field-strength clinical MRI scans in participants with neurologic symptoms was performed. These were part of a prospective observational study (August 2020 to December 2021) at Massachusetts General Hospital (exclusion criteria: inability to lay flat, body habitus preventing low-field-strength MRI, presence of MRI contraindications). Three well-established automated segmentation tools were applied to three sets of scans: high-field-strength (1.5-3 T, reference standard), low-field-strength (0.064 T), and synthetic high-field-strength images generated from the low-field-strength data with the CNN. Statistical significance of correlations was assessed with Student t tests. Correlation coefficients were compared with Steiger Z tests. Results Eleven participants (mean age, 50 years ± 14; seven men) had full cerebrum coverage in the images without motion artifacts or large stroke lesion with distortion from mass effect. Direct segmentation of low-field-strength MRI yielded nonsignificant correlations with volumetric measurements from high field strength for most ROIs (P > .05). Correlations largely improved when segmenting the synthetic images: P values were less than . 05 for all ROIs (eg, for the hippocampus [r = 0.85; P < .001], thalamus [r = 0.84; P = .001], and whole cerebrum [r = 0.92; P < .001]). Deviations from the model (z score maps) visually correlated with pathologic abnormalities. Conclusion This work demonstrated proof-of-principle augmentation of portable MRI with a machine learning super-resolution algorithm, which yielded highly correlated brain morphometric measurements to real higher resolution images. © RSNA, 2022 Online supplemental material is available for this article.

GRSM: SECURE GEOMETRIC RANGE SEARCH OVER ENCRYPTED SPATIAL DATA

Nowadays, outsourcing the data to the cloud server is a natural activity auctioned by several cloud users. The outsourced data may contain sensitive information. The cloud technologies are very much improved that attracts many Location based Services (LBS) companies. The overall theme of the cloud data resides at the distant server is to be managed with minimal computation by data owner and data users. The data is hived away in encrypted form to prevent anonymity activities. Reachability is one of the issues faced between cloud users and LBS companies. A novel and lightweight scheme, named, Geometric Range Search Model (GRSM) that retrieves the search data from ciphertext dataset. The data is considered as points and the group of points denotes the ciphertext database. Bloom filter is the filter that contains all possible combination of search tokens. The proposed GRSM contain three phases, namely, Encryption phase, Token generation phase and Search phase. Each phase serves as input/ output to retrieve the search data. An experimental result shows the effectiveness of the proposed algorithm.
