The presence of arsenic in various types of mineral trioxide aggregate (MTA) and Portland cements were evaluated to verify if they comply with the ISO-recommended limit for water-based cements of 2 mg arsenic/kg material. An amount of 5 mL of hydrochloric acid was added to 2 g each of MTA and Portland cement to be analyzed. After 15 minutes, the material was filtered and the volume of supernatant was diluted with reagent-grade water up to 40 mL. Atomic absorption spectrophotometry readings were performed in triplicate. The following mean values were obtained: CPM (Egeo, Buenos Aires, Argentina) 11.06 mg/kg; CPM sealer (Egeo) 10.30 mg/kg; MTA-Obtura (Angelus, Londrina, PR, Brazil) 0.39 mg/kg; Experimental MTA: 10.30 mg/kg; White MTA-Angelus (Angelus) 1.03 mg/kg; Gray MTA-Angelus (Angelus) 5.91 mg/kg; ProRoot-MTA (Dentsply/Tulsa Dental Specialties, Tulsa, OK) 5.25 mg/kg; Gray Portland cement (Votorantim Cimentos, Cubatão, SP, Brazil): 34.27 mg/kg; and White Portland cement (Cimento Rio Branco, Rio de Janeiro, RJ, Brazil) 0.52 mg/kg. All tested materials presented arsenic in their composition. The form of arsenic was not analyzed nor the toxicity of the arsenic found. Only MTA-Obtura, White MTA-Angelus, and White Portland cement presented arsenic levels below the limit set in the ISO 9917-1 standard.

Background: It is important to have a replicable easy method for monitoring atrophy progression in Alzheimer's disease. Volumetric methods for calculating hippocampal volume are time-consuming and commonly used in research. Visual assessments of medial temporal lobe atrophy (vaMTA) is a rapid method for clinical use. This method has not been tested in a large non-demented population in comparison with volumetry measurements. Since hippocampal volume decreases with time even in normal aging there is also a need to study the normal age differences of medial temporal lobe atrophy. Purpose: To compare visual assessment of medial temporal lobe atrophy (vaMTA) with hippocampal volume in a healthy, non-demented elderly population. To describe normal ageing using vaMTA. Material and Methods: Non-demented individuals aged 60, 66, 72, 78, 81, 84, and {>=}87 years old were recruited from the Swedish National study on Ageing and Care in Kungsholmen (SNAC-K), Sweden. Standard magnetic resonance imaging (MRI) scans, vaMTA, and calculations of hippocampal volumes were performed in 544 subjects. Results: Significant correlation (rs = -0.32, P < 0.001, sin; and rs = -0.26, P < 0.001, dx) was found between hippocampal volume measurements and vaMTA. In normal ageing, almost 95% of {<=}66-year-olds had a medial temporal lobe atrophy (MTA) score {<=}1, with possible scores ranging from 0 to 4. Subjects aged 72, 78, and 81 years scored {<=}2, while the two oldest age groups had scores {<=}3. Conclusion: There was a highly significant correlation between volumetric measurements of the hippocampus and MTA scoring. In normal ageing, there is increasing MTA score. For non-demented elderly individuals {<=}70 years, an MTA score of 0-1 may be considered normal, compared with MTA {<=}2 for 70-80-years and MTA 3 for >80-year-old individuals.

BioAggregate™ is a novel material introduced for use as a root-end filling material. It is tricalcium silicate-based, free of aluminium and uses tantalum oxide as radiopacifier. BioAggregate contains additives to enhance the material performance. The purpose of this research was to characterize the un-hydrated and hydrated forms of BioAggregate using a combination of techniques, verify whether the additives if present affect the properties of the set material and compare these properties to those of MTA Angelus™. Un-hydrated and hydrated BioAggregate and MTA Angelus were assessed. Un-hydrated cement was tested for chemical composition, specific surface area, mineralogy and kinetics of hydration. The set material was investigated for mineralogy, microstructure and bioactivity. Scanning electron microscopy, X-ray energy dispersive spectroscopic analysis, X-ray fluorescence spectroscopy, X-ray diffraction and isothermal calorimetry were employed. The specific surface area was investigated using a gas adsorption method with nitrogen as the probe. BioAggregate was composed of tricalcium silicate, tantalum oxide, calcium phosphate and silicon dioxide and was free of aluminium. On hydration, the tricalcium silicate produced calcium silicate hydrate and calcium hydroxide. The former was deposited around the cement grains, while the latter reacted with the silicon dioxide to form additional calcium silicate hydrate. This resulted in reduction of calcium hydroxide in the aged cement. MTA Angelus reacted in a similar fashion; however, since it contained no additives, the calcium hydroxide was still present in the aged cement. Bioactivity was demonstrated by deposition of hydroxyapatite. BioAggregate exhibited a high specific surface area. Nevertheless, the reactivity determined by isothermal calorimetry appeared to be slow compared to MTA Angelus. The tantalum oxide as opposed to bismuth oxide was inert, and tantalum was not leached in solution. BioAggregate exhibited

Confidentiality in psychological practice: a decrepit concept?

Science.gov (United States)

McMahon, M; Knowles, A D

1995-11-01

Although the principle of confidentiality in the relationship between psychologists and client has been vaunted, and is emphasised in the Australian Psychological Society's Code of Professional Conduct (the APS code; 1994), the confidentiality of this relationship is circumscribed by the absence of legal protections, the ethical beliefs of psychologists, institutional practices, and the provisions of the APS code itself. Lack of privilege in judicial proceedings, and statutory obligations to report certain types of behaviour, mandate breaches of confidentiality in some circumstances. Ethical beliefs of psychologists may support disclosure, especially where it is believed that there is danger of serious physical harm to the client or others. Multidisciplinary teams and institutional settings require the exchange of information for optimal delivery of services. Recent amendments to the APS code may require disclosure without the client's consent when a client is believed to be suicidal. Such developments, when considered at all, are typically regarded as exceptions to a general obligation of confidentiality. However, discussion of exceptions presupposes agreement on fundamental principle: the significance of, and rationale for, confidentiality in the psychologist-client relationship. It is argued in this paper that the obligation of confidentiality has been assumed rather than vigorously analysed and empirically explored. A critical examination of this obligation is the most appropriate starting point for the rehabilitation of contemporary principles of confidentiality in the psychologist-client relationship.

The purpose of this investigation was to evaluate the physicochemical properties of gray and white structural and nonstructural Portland cement, gray and white ProRoot MTA and MTA BIO. The water/powder ratio, setting time, solubility and pH (hydrogen-ion potential) changes of the materials were evaluated. Tests followed specification #57 from the American National Standard Institute/American Dental Association (2000) for endodontic sealing materials and pH was determined by a digital pH meter. The test results were statistically analyzed by variance analyses for global comparison and by the complementary Tukey's test for pairwise comparisons (5%). Considering the water/powder ratio, no significant difference (p > 0.05) was observed among the cements. MTA BIO (33.10 +/- 2.30) had the lowest setting time (p Portland cement (2.55 +/- 0.08) had the highest solubility (p 0.05) was observed among materials when considering pH evaluation. The pH levels were highly alkaline immediately after immersion in solution, remaining stable throughout the test period. The authors conclude that the cements had similar water/powder proportions. MTA BIO had the shortest setting time and gray ProRoot MTA had the lowest solubility. All cements had similar behavior in the pH analysis.

To assess periradicular lesions clinically and by computed tomography (CT) after endodontic surgery using either Portland cement or mineral trioxide aggregate (MTA) as a root-end filling material. Three patients diagnosed with periradicular lesions by cone-beam CT underwent endodontic surgery with root-end filling. Patient A was treated with MTA as the root-end filling material, patient B was treated with Portland cement and patient C had two teeth treated, one with MTA and the other with Portland cement. Six months after surgery, the patients were assessed clinically and by CT scan and the obtained results were compared. Periradicular tissue regeneration was observed in all cases, with no significant differences in bone formation when comparing the use of MTA and Portland cement as root-end filling materials. Both mineral trioxide aggregate and Portland cement were successful in the treatment of periradicular lesions.

The 180mTa nucleus is the rarest isotope in the universe, existing only in an isomeric state at 77.2 keV (Jπ = 9-) with half-life of greater than 7.1 ×1015 years. The stellar production of this high-spin isomer has been a challenging astrophysical problem. Cross-section measurements for the depopulation of the 180mTa isomer with monoenergetic photon beams of energies 2.5 and 3.1 MeV have been carried out at the HI γS facility. The activated Ta foils of natural abundance and containing 14.4 mg of 180mTa were γ-ray counted at TUNL's low background facility using a 13% planar HPGe detector. A 8'' ×12'' NaI detector in combination with the standard HI γS scintillator paddle system was employed for absolute photon-flux determination. Preliminary results will be discussed, and measurements at lower energies are planned. This work was supported by the U.S. DOE under Grant NO. DE-FG02-97ER41033.

On deep carious lesions, only thin dentine remains, causing a high risk of pulp exposure during the removal of all infected dentine. A minimally invasive technique is required, such as a partial caries excavation method in the infected dentine tissue and the use of bioactive material that can promote (Mineral Trioxide Aggregate) MTA remineralization. To compare the remineralization of deep carious lesion-affected dentine with the removal of some and all the infected dentine after the application of MTA. Subjects were divided into two groups: group I had only some parts of the infected dentine removed before MTA application, while group II had all the infected dentine removed before MTA application. Each group was measured on the pixel grey value before the treatment and again four weeks after the MTA application, and then the results were compared. Furthermore, the enhancement of both groups’ grey values were compared. Remineralization occurred in both groups after the MTA application. There was no significant difference in the remineralization level of the affected dentine in both groups I and II four weeks after the MTA application. Remineralization occurred in the affected dentine in both groups, either by removing only some parts or all the infected dentine in the deep carious lesion.

Full Text Available Introduction: In direct pup capping, the exposed pulp is directly capped with a capping material to provoke a dentinal bridge formation to seal the exposed area.The aim of this study was to evaluate the pulpal response to MTA and capsaicin in cats. Methods: The sample for this experimental study consisted of 24 canines of cats, weighed approximately 3-4kg. After sedation, the teeth were cut and exposed at 3mm above cementoenamel junction, then divided into two groups: 1 direct pulp capping with MTA 2 direct pulp capping with Capsaicin. The cavities were filled with glass ionomer cement (Fuji IX. The cats were sacrificed in the first, second, and fourth weeks 4 canine teeth were extracted for the purpose of histologic analysis. 6Serial sections were cut parallel to the longitudinal axis of the canines. The sections were stained with hematoxylin & eosin, and were observed and analyzed using a light microscope. Results: In both groups treated with MTA and capsaicin, the inflammation decreased during weeks1, 2, and 4. Less inflammation was seen in MTA group but there was no statistical difference between the two groups (p=0.22. In the group treated with capsaicin, necrosis was observed in every 12 samples, but in the other group treated with MTA, only 1 pulp necrosis was seen in the first week (p=0.000. There was no significant difference in dentinal barrier formation, inflammatory response, and soft tissue changes between the two groups. Conclusions: The results of this study showed that capsaicin can decrease the severity of inflammation, but it is ineffective in dentinal barrier formation.

To evaluate the biological response of the periodontium adjacent to furcation perforations in rat molars filled with Endo-CPM-Sealer (CPM), MTA-Angelus (MTA) or zinc oxide-eugenol cement (ZOE). The pulp chamber floors of maxillary right first molar teeth were perforated and sealed with CPM, mineral trioxide aggregate (MTA) or ZOE; the left first molars, without any treatment, were used as controls (CG). After 7, 15, 30 and 60 days, fragments of maxilla were fixed, decalcified and embedded in paraffin. Sections were stained with H&E, Masson's trichrome and submitted to tartrate-resistant acid phosphatase (TRAP) reaction, used as an osteoclast marker. The width of the periodontal space, the numerical density of inflammatory cells and the number of TRAP-positive osteoclasts in the bone surface were measured, and statistical analyses were performed using analysis of variance and Tukey test (P ≤ 0.05). In all experimental groups, the greatest number of inflammatory cells was observed at 7 days, especially in the ZOE group. In this group, the intense inflammatory process was related to a significant increase (P ≤ 0.05) in the number of osteoclasts and, thereby, in an increase in the width of the periodontal space. At 60 days, no significant differences in osteoclast numbers amongst CPM, MTA and CG groups occurred; the periodontal space was also significantly reduced in the experimental groups in comparison with the initial periods. However, in the ZOE group, the periodontal space was significantly larger (P ≤ 0.05) in comparison with MTA-based materials. The periodontium adjacent to perforations filled with MTA and CPM exhibited clear evidence of re-establishment and thus better biocompatibility than ZOE. © 2010 International Endodontic Journal.

Pulpotomy is the most performed and controversial therapeutic in pediatric dentistry. Formocresol is known to have a toxic effect on living tissues, a mutagenic and carcinogenic potential with a systemic uptake of formocresol via pulpotomized teeth, other alternative products have been investigated. 40 molars were pulpotomized using Micro Mega Mineral Trioxide Aggregate (MM-MTA), which eliminates the need for the use of formocresol. The effects of this material were evaluated both clinically and radiographically. Post-operative control examinations were performed at 1, 6, 12, and 18 months trying to detect spontaneous or stimulated pain, pathological tooth mobility, abscesses or fistulas, internal or external pathological tooth resorption, periapical bone destruction, or canal obliteration. Pain was absent at 18 months post operatively. Thirty six molar treated with the MM-MTA didn't show any mobility or pain, one molar presented a pathological resorption and one molar presented an abscess without a fistula at 12 month. The observations were compared to others related to formocresol, ferric sulfate, MTA, and laser pulpotomies, using the Chi-square test x2. The abundance of positive result strongly demonstrate that the MM-MTA pulpotomy on carious temporary molars is a promising technique.

Full Text Available ABSTRACT Objective: The aim of the present study was to evaluate and compare the cytotoxic effects of Biodentine and MTA on dental pulp stem cells (DPSCs and to assess cell viability and adherence after material exposure to an acidic environment. Material and Methods: DPSCs were cultured either alone or in contact with either: Biodentine; MTA set for 1 hour; or MTA set for 24 hours. After 4 and 7 days, cell viability was measured using the MTT assay. Biodentine and MTA were also prepared and packed into standardized bovine dentin disks and divided into three groups according to the storage media (n=6/group: freshly mixed materials without storage medium (Group A; materials stored in saline (Group B; materials stored in citric acid buffered at pH 5.4 (Group C. After 24 hours, DPSCs were introduced in the wells and cell adherence, viability, and cellular morphology were observed via confocal microscopy after three days of culture. Cell viability was analyzed using repeated-measures analysis of variance test with Tukey's post hoc tests (α=0.05. Results: Biodentine expressed significantly higher cell viability compared with all other groups after 4 days, with no differences after 7 days. Notably, cell viability was significantly greater in 24-hour set MTA compared with 1-hour set MTA and control groups after 7 days. Material exposure to an acidic environment showed an increase in cell adherence and viability in both groups. Conclusions: Biodentine induced a significantly accelerated cell proliferation compared with MTA. Setting of these materials in the presence of citric acid enhanced DPSC viability and adherence.

The aim of this study was to evaluate the sealing ability of mineral trioxide aggregate (MTA Bio) combined with different mixing agents (distilled water, chlorhexidine, doxycycline), used as an apical root-end filling material. Forty-two extracted human teeth were divided into three groups (n = 12); six teeth were used as controls. Root-ends were resected at 90 degrees, 3 mm from the apex. Root-end cavities were prepared using ultrasonic tips and filled with MTA Bio plus distilled water, 2% chlorhexidine solution, or 10% doxycycline solution. Apical sealing was assessed by microleakage of 50% silver nitrate solution. Roots were longitudinally sectioned in a buccolingual plane and analyzed using an operating microscope (20× magnification). Depth of dye leakage into the dentinal walls was measured in millimeters. Results were analyzed using ANOVA and Tukey's test (P = 0.05). MTA Bio plus distilled water showed significantly higher mean leakage results (1.06 mm) when compared with MTA Bio plus doxycycline (0.61 mm), and higher, although not significant, results when compared with MTA Bio plus chlorhexidine (0.79 mm). In conclusion, replacing distilled water with two biologically active mixing agents (doxycycline and chlorhexidine) did not alter the sealing properties of MTABio. The antimicrobial properties of these combinations should be further investigated.

This study compared the clinical and radiographic effectiveness of mineral trioxide aggregate (MTA) and Portland cement (PC) as pulp dressing agents in carious primary teeth. Thirty carious primary mandibular molars of children aged 5-9 years old were randomly assigned to MTA or PC groups, and treated by a conventional pulpotomy technique. The teeth were restored with resin modified glass ionomer cement. Clinical and radiographic successes and failures were recorded at 6, 12, 18 and 24-month follow-up. All pulpotomised teeth were clinically and radiographically successful at all follow-up appointments. Six out of 15 teeth in the PC group and five out of 14 teeth in the MTA group exfoliated throughout the follow-up period. No statistically significant difference regarding dentine bridge formation was found between both groups throughout the follow-up period. As far as pulp canal obliteration is concerned, a statistically significant difference was detected at 6-month follow-up (p <0.05), since the beginning of mineralised material deposition could be radiographically detected in 100% and 57.14% of the teeth treated with PC and MTA, respectively. PC may serve as an effective and less expensive MTA substitute in primary molar pulpotomies. Further studies and longer follow-up assessments are needed.

The aim of this study was to determine, by Atomic Absorption Spectrometry (AAS), the concentration levels of 11 metals in Type V gray and structural white PC, ProRoot MTA, and MTA Bio. Samples, containing one gram of each tested cement, were prepared and transferred to a 100 mL Teflon tube with a mixture of 7.0 mL of nitric acid and 21 mL of hydrochloric acid. After the reaction, the mixture was filtered and then volumed to 50 mL of distilled water. For each metal, specific patterns were determined from universal standards. Arsenic quantification was performed by hydride generator. The analysis was performed five times and the data were statistically analyzed at 5% level of significance. Only the cadmium presented concentration levels of values lower than the quantification limit of the device. The AAS analysis showed increased levels of calcium, nickel, and zinc in structural white PC. Type V PC presented the greatest concentration levels of arsenic, chromium, copper, iron, lead, and manganese (P cements, and the lowest concentration levels were observed in Portland cements, while the highest were observed in ProRoot MTA. Both PC and MTA-based cements showed evidence of metals inclusion.

The aim of this study was to evaluate the response of rat subcutaneous tissue to MTA Fillapex® (Angelus), an experimental root canal filling material based on Portland cement and propylene glycol (PCPG), and a zinc oxide, eugenol and iodoform (ZOEI) paste. These materials were placed in polyethylene tubes and implanted into the dorsal connective tissue of Wistar rats for 7 and 15 days. The specimens were stained with hematoxylin and eosin, and evaluated regarding inflammatory reaction parameters by optical microscopy. The intensity of inflammatory response against the sealers was analyzed by two blinded and previously calibrated examiners for all experimental periods (kappa=0.96). The histological evaluation showed that all materials caused a moderate inflammatory reaction at 7 days, which subsided with time. A greater inflammatory reaction was observed at 7 days in the tubes filled with ZOEI paste. Tubes filled with MTA Fillapex presented some giant cells, macrophages and lymphocytes after 7 days. At 15 days, the presence of fibroblasts and collagen fibers was observed indicating normal tissue healing. The tubes filled with PCPG showed similar results to those observed in MTA Fillapex. At 15 days, the inflammatory reaction was almost absent at the tissue, with several collagen fibers indicating normal tissue healing. Data were analyzed by the nonparametric Kruskal-Wallis test (α=0.05). Statistically significant difference (p0.05). MTA Fillapex and Portland cement added with propylene glycol had greater tissue compatibility than the PCPG paste.

To assess the prevalence of psychotic symptoms among youths (14-25 years of age) with a childhood diagnosis of attention-deficit/hyperactivity disorder (ADHD) combined type. Participants in the Multimodal Treatment Study of Children with ADHD (MTA) and a local normative comparison group (LNCG) were systematically assessed 6, 8, 10, 12, 14, and 16 years after the original enrollment at a mean age of 8.5 years. Trained research assistants administered a psychosis screener, and positive screens were referred to study clinicians to confirm or exclude psychosis. Possible associations between screening positive and alcohol or substance use were assessed. Data were available from 509 MTA participants (88% of original MTA sample; mean age 25.1 years) and 276 LNCG participants (96% of original sample; mean age 24.6 years) at year 16. Twenty-six MTA participants (5%; 95% CI 3-7) and 11 LNCG participants (4%; 95% CI 2-6) screened positive for at least 1 psychotic symptom (p = .60). Most psychotic symptoms were transient. The prevalence of clinician-confirmed psychotic symptoms was 1.1% (95% CI 0.2-2.1) in the MTA group and 0.7% (0-1.7) in the LNCG (p = .72). Greater cannabis use was reported by those who screened positive (p ADHD increased the risk for psychotic symptoms. In the ADHD and normative comparison groups, more frequent cannabis use was associated with a greater likelihood of experiencing psychotic symptoms, thus supporting the recommendation that youth should not use cannabis.

The aim of this study was to determine the chemical composition and the phases' microstructure of Aureoseal Plus (OGNA, Italy) and ProRoot MTA (Dentsply Tulsa Dental, USA) and to compare their characteristics. Study Design: Comparing Aureoseal Plus and ProRoot MTA microstructure by means of several analyses type. The chemical analysis of the two cements was assessed following the UNI EN ISO 196-2 norm. X-Ray fluorescence (XRF) was used to determine the element composition. The crystalline structure was analysed quantitatively using x-ray diffraction (XRD). Powders morphology was evaluated using a scanning electron microscope (SEM) with backscattering detectors, and a field emission scanning electron microscope (FESEM). Elemental analysis was performed by energy dispersive x-ray analysis (EDS). The semi-quantitative XRF analysis showed the presence of heavy metal oxides in both cements. The XRD spectra of the two cements reported the presence of dicalcium silicate, tricalcium silicate, tricalcium aluminate, tetracalcium aluminoferrite, bismuth oxide and gypsum. SEM analysis showed that ProRoot MTA powder is less coarse and more homogeneous than Aureoseal. Both powders are formed by particles of different shapes: round, prismatic and oblong. The EDS analysis showed that some ProRoot MTA particles, differently from Aureoseal, contain Ca, Si, Al and Fe. Oblong particles in ProRoot and Aureoseal are rich of bismuth. The strong interest in developing new Portland cement-based endodontic sealers will create materials with increased handling characteristics and physicochemical properties. A thorough investigation on two cement powders was carried out by using XRF, XRD, SEM and EDS analysis. To date there was a lack of studies on Aureoseal Plus. This cement is similar in composition to ProRoot MTA. Despite that it has distinctive elements that could improve its characteristics, resulting in a good alternative to MTA.

The aim of this in vitro study was to determine the liquid-powder ratio, setting time, solubility, dimensional change, pH, and radiopacity of white structural and non-structural Portland cement, ProRoot MTA and MTA Bio, associated with a 2% glycolic solution containing Aloe Vera, as vehicle. Five samples of each material were used for each test, according to the American National Standards Institute/American Dental Association (ANSI/ADA) specification No. 57. Statistical analyses were performed using ANOVA and Tukey's test at 5% significance. When sample distribution was not normal, non-parametric analysis of variance and the Kruskal-Wallis test were used ( α =0.05). No statistical differences were found in liquid-powder ratios among the tested materials. ProRoot MTA showed the longest setting time. Dimensional change values were acceptable in all groups. Also, no significant differences were found in pH values and pH was alkaline in all samples throughout the experiment. Mean radiopacity results obtained for white Portland cements did not meet ANSI/ADA requirements, and were significantly lower than those obtained for MTA-based cements. Finally, Portland cements showed significantly higher mean solubility values compared to the other samples. The physicochemical properties of the tested materials in association with Aloe Vera were compatible with ANSI/ADA requirements, except for the white Portland cements, which failed to meet the radiopacity specification.

Absence of periapical healing after orthograde retreatment using an apical plug with mineral trioxide aggregate (MTA) can require surgical intervention. A patient with a root-filled maxillary central incisor with chronic apical periodontitis and sinus tract was referred for endodontic retreatment. Excessive apical enlargement was verified, indicating an MTA apical plug placement; however, an unintentional extrusion of MTA occurred during this step. The root canal was filled with gutta-percha and sealer, and periodic recalls were scheduled. The sinus tract was observed after six months and the lesion remained unaltered, although the extruded MTA had resorbed; therefore, an apicoectomy and retrograde root-end filling with MTA were performed. Absence of sinus tract, normal clinical aspect, and complete repair of the lesion were observed at the two-year follow-up.

Some manufacturers have recently added specific components to improve the ease of handling and insertion material properties of MTA in order to create MTA-based sealers. The aim of this study was to evaluate the healing of periapical lesions in canine teeth after a single session of endodontic treatment with MTA Fillapex® compared with Sealapex® or Endo-CPM-Sealer®. Sixty-two root canals were performed on two 1-year-old male dogs. After coronal access and pulp extirpation, the canals were exposed to the oral cavity for 6 months in order to induce periapical lesions. The root canals were prepared, irrigated with a solution of 2.5% sodium hypochlorite and filled with gutta-percha and different sealers, according to the following groups: 1) Sealapex®; 2) Endo-CPM-Sealer®; and 3) MTA Fillapex®. Some teeth with periapical lesions were left untreated for use as positive controls. Healthy teeth were used as negative controls. After 6 months, the animals were sacrificed and serial sections from the roots were prepared for histomorphologic analysis and stained with hematoxylin and eosin and the Brown and Brenn technique. The lesions were scored according to pre-established histomorphologic parameters and the scores statistically analyzed using the Kruskal-Wallis test. All 3 materials produced similar patterns of healing (p>0.05); in particular, persistent inflammation and absence of complete periapical tissue healing were consistently noted. Preparation of the infected root canals followed by filling with the materials studied was insufficient to provide complete healing of the periapical tissues.

Objective. The aim of this study was to evaluate the cytotoxicity and cellular adhesion of Mineral Trioxide Aggregate (MTA) and Biodentine (BD) on periodontal ligament fibroblasts (PDL). Methods. PDL cells were obtained from nonerupted third molars and cultured; MTS cellular profusion test was carried out in two groups: MTA and BD, with respective controls at different time periods. Also, the LIVE/DEAD assay was performed at 24 h. For evaluation of cellular adhesion, immunocytochemistry was conducted to discern the expression of Integrin β1 and Vinculin at 12 h and 24 h. Statistical analysis was performed by the Kruskal-Wallis and Mann-Whitney U tests. Results. MTA and BD exhibited living cells up to 7 days. More expressions of Integrin β1 and Vinculin were demonstrated in the control group, followed by BD and MTA, which also showed cellular loss and morphological changes. There was a significant difference in the experimental groups cultured for 5 and 7 days compared with the control, but there was no significant statistical difference between both cements. Conclusions. Neither material was cytotoxic during the time evaluated. There was an increase of cell adhesion through the expression of focal contacts observed in the case of BD, followed by MTA, but not significantly.

Background: It is important to have a replicable easy method for monitoring atrophy progression in Alzheimer's disease. Volumetric methods for calculating hippocampal volume are time-consuming and commonly used in research. Visual assessments of medial temporal lobe atrophy (vaMTA) is a rapid method for clinical use. This method has not been tested in a large non-demented population in comparison with volumetry measurements. Since hippocampal volume decreases with time even in normal aging there is also a need to study the normal age differences of medial temporal lobe atrophy. Purpose: To compare visual assessment of medial temporal lobe atrophy (vaMTA) with hippocampal volume in a healthy, non-demented elderly population. To describe normal ageing using vaMTA. Material and Methods: Non-demented individuals aged 60, 66, 72, 78, 81, 84, and ≥87 years old were recruited from the Swedish National study on Ageing and Care in Kungsholmen (SNAC-K), Sweden. Standard magnetic resonance imaging (MRI) scans, vaMTA, and calculations of hippocampal volumes were performed in 544 subjects. Results: Significant correlation (rs = -0.32, P 80-year-old individuals

4-Methylthioamphetamine (4-MTA) is a scheduled designer drug that has appeared on the illicit drug market and led to several non-fatal or even fatal poisonings. Only few data are available on its metabolism. The first aim of this study was to identify the 4-MTA metabolites in human urine and then to study whether the authors' STA procedure is suitable for screening for and identification of 4-MTA and/or its metabolites in urine. After enzymatic cleavage of conjugates, solid-phase extraction (SPE) and acetylation the following metabolites could be identified by full-scan gas chromatography-mass spectrometry (GC-MS): deamino-oxo 4-MTA, deamino-hydroxy 4-MTA, ring hydroxy and beta-hydroxy 4-MTA. 4-MTA sulfoxide could be identified as possible artifact. In urine samples after enzymatic hydrolysis, acidic extraction, and methylation, 4-methylthiobenzoic acid could be identified. The authors' systematical toxicological analysis (STA) procedure using full-scan GC-MS after acid hydrolysis, liquid-liquid extraction (LLE) and acetylation allowed detection of 4-MTA as target analyte plus all the above-mentioned metabolites with the exception of 4-methylthiobenzoic acid. The extraction efficiency of 4-MTA was approximately 70% and the limit of detection (LOD) was 30 ng/ml (S/N 3).

Full Text Available Chloroplast development is an integral part of plant survival and growth, and occurs in parallel with chlorophyll biosynthesis. However, little is known about the mechanisms underlying chloroplast development in hexaploid wheat. Here, we obtained a spaceflight-induced wheat albino mutant mta. Chloroplast ultra-structural observation showed that chloroplasts of mta exhibit abnormal morphology and distribution compared to wild type. Photosynthetic pigments content was also significantly decreased in mta. Transcriptome and chloroplast proteome profiling of mta and wild type were done to identify differentially expressed genes (DEGs and proteins (DEPs, respectively. In total 4,588 DEGs including 1,980 up- and 2,608 down-regulated, and 48 chloroplast DEPs including 15 up- and 33 down-regulated were identified in mta. Classification of DEGs revealed that most were involved in chloroplast development, chlorophyll biosynthesis, or photosynthesis. Besides, transcription factors such as PIF3, GLK and MYB which might participate in those pathways were also identified. The correlation analysis between DEGs and DEPs revealed that the transcript-to-protein in abundance was functioned into photosynthesis and chloroplast relevant groups. Real time qPCR analysis validated that the expression level of genes encoding photosynthetic proteins was significantly decreased in mta. Together, our results suggest that the molecular mechanism for albino leaf color formation in mta is a thoroughly regulated and complicated process. The combined analysis of transcriptome and proteome afford comprehensive information for further research on chloroplast development mechanism in wheat. And spaceflight provides a potential means for mutagenesis in crop breeding.

We studied peaks of calcium hydroxyapatite - CHA on defects grafted with MTA, treated or not with Light Emitting Diode - LED or IR Laser. 54 rats were divided in 6 groups each subdivided into 3 subgroups (15,21,30d). LED (λ850 +/- 10nm) or IR Laser (λ850 nm) was applied over (LED) or in 4 points around the defect at 48 h intervals for 15 days. Raman readings were taken at the surface of the defect. The smaller overall intensity of the peak was found in Group MTA + Laser (1510.2 +/- 274.1) and the highest on Group LED (2322 +/- 715). There were no statistically significant differences between non-irradiated subjects on regards the CHA peaks. On the other hand, there were statistically significant differences between the Group Clot and LED, Clot and Laser, and Clot and MTA + Laser (p =0.01, p = 0.02, p = 0.003). There were no significant differences between Group MTA and MTA + LED (p=0.2) but significant differences were seen between Groups MTA and MTA + Laser (p=0.01). Significant differences were also observed between Groups LED and Laser (p <0.001) and between Groups MTA + LED and MTA + Laser (p=0.009). MTA, due to its characteristics, seemed to be directly affected by the light. However, the use of either phototherapy positively affected bone healing similarly as observed on different studies using other biomaterials. The overall analysis of our results indicated that the use of either light source resulted in a better, more advanced, and of quality bone repair.

Full Text Available Apical sealing is essential for the success of paraendodontic surgery, so any procedure that may favor an adequate sealing of the apical remainder should be performed. The purpose of this study was to evaluate the influence of diode laser irradiation on the apical sealing of root-end cavities with MTA retrofillings. Root canals in twenty extracted human teeth were shaped with K-files and filled with gutta-percha. The apexes were cut off and root-end preparations were performed. The roots were divided randomly in 2 groups. Group 1 (ten specimens was retrofilled with MTA. Group 2 was irradiated with diode laser, with 1 W for 20 seconds, on the apical surface and root end cavity before retrofilling with MTA. The specimens had their external surfaces impermeabilized with cyanoacrylate, except for the apical surface, and were then immersed in 1% rhodamine B dye for 72 h and placed in plaster stone. After that, the specimens were submitted to longitudinal abrasion until half of the root remained. The linear dye leakage was observed in these mid-roots between the root canal wall and retrofilling. The linear dye leakage was measured with Image Lab software, and the results were statistically analyzed with Student's t test. There were no statistically significant differences between the two groups (p > 0.05. The diode laser irradiation did not improve the apical sealing of MTA retrofillings under the conditions of this in vitro study.O selamento apical é fundamental para o sucesso da cirurgia parendodôntica.

Conclusions The epoxy resin-based cement MBPc had lower bacterial leakage compared with the calcium silicate-based cements MTA and CPM.

Confidentiality and personal integrity.

Edgar, A

This paper uses the social theory of Erving Goffman in order to argue that confidentiality should be understood in relation to the mundane social skills by which individuals present and respect specific self-images of themselves and others during social interaction. The breaching of confidentiality is analysed in terms of one person's capacity to embarrass another, and so to expose that person as incompetent. Respecting confidentiality may at once serve to protect the vulnerable from an unjust society, and yet also protect the guilty from just accusation. Ethical reasoning about confidentiality must therefore recognize the dangers of prejudice and violence inherent in decisions to breach or to respect confidentiality. Case studies are used to illustrate the efficacy of this account, culminating with analyses of three examples from the UKCC document Confidentiality.

The aim of the present study was to evaluate the effects of a novel bioceramic nanoparticular cement, BioAggregate (Innovative Bioceramix, Vancouver, BC, Canada), on the adhesion, migration, and attachment of human dental pulp cells (HDPCs) and to compare its performance with that of ProRoot mineral trioxide aggregate (MTA) (Dentsply, Tulsa, OK). Primary cultured HDPCs were treated with various dilutions of BioAggregate and MTA extracts to assess the cell viability using the Cell Counting Kit-8 (Dojindo, Kumamoto, Japan). Cell adhesion assay was performed using type I collagen-coated plates. An in vitro scratch wound healing model was used to determine cell migration. Focal adhesion formation and cytoskeleton organization were further examined by double immunofluorescence labeling for vinculin and fibrous actin. To assess cell attachment, HDPCs were directly seeded onto the material surfaces and observed by scanning electron microscopy. HDPCs exposed to BioAggregate extracts showed the highest viabilities at all extract concentrations at 24 and 48 hours, whereas cells exposed to original MTA extracts displayed suppressed viabilities at 72 hours compared with the control. Treatment with BioAggregate extracts enhanced cellular adhesion and migration of HDPCs in a concentration-dependent manner, which was superior to the effects induced by MTA extracts. Immunofluorescence staining indicated that both BioAggregate and MTA optimized focal adhesion formation and stress fiber assembly. Furthermore, scanning electron microscopic analysis revealed that HDPCs attached onto BioAggregate were more flattened and exhibited better spreading than cells on MTA. BioAggregate is able to promote cellular adhesion, migration, and attachment of HDPCs, indicating its excellent cytocompatibility. Therefore, BioAggregate appears to be a possible alternative to MTA for pulp capping. Copyright © 2014 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

The nucleosome remodeling and deacetylase (NuRD) complex is a widely conserved transcriptional co-regulator that harbors both nucleosome remodeling and histone deacetylase activities. It plays a critical role in the early stages of ES cell differentiation and the reprogramming of somatic to induced pluripotent stem cells. Abnormalities in several NuRD proteins are associated with cancer and aging. We have investigated the architecture of NuRD by determining the structure of a subcomplex comprising RbAp48 and MTA1. Surprisingly, RbAp48 recognizes MTA1 using the same site that it uses to bind histone H4, showing that assembly into NuRD modulates RbAp46/48 interactions with histones. Taken together with other results, our data show that the MTA proteins act as scaffolds for NuRD complex assembly. We further show that the RbAp48-MTA1 interaction is essential for the in vivo integration of RbAp46/48 into the NuRD complex. © 2014 by The American Society for Biochemistry and Molecular Biology, Inc.

Darvell, B W; Wu, R C T

2011-05-01

To review the current status and understanding of Portland cement-like endodontic materials commonly referred to by the trade designation "MTA" (alias "Mineral Trioxide Aggregate"), and to present an outline setting reaction scheme, hitherto unattempted. The literature was searched using on-line tools, overlapping an earlier substantial review to pick up any omissions, including that in respect of ordinary Portland cement (OPC), with which MTA shares much. The search was conducted for the period January 2005 to December 2009 using 'MTA', 'GMTA', 'WMTA', and 'mineral AND trioxide AND aggregate' as keywords, with various on-line search engines including ScienceDirect (http://www.sciencedirect.com), SAGE Journals Online (http://online.sagepub.com), Wiley Online Library (http://onlinelibrary.wiley.com), SciELO Scientific electronic library online (http://www.scielo.br/scielo.php), JSTOR (http://www.jstor.org), and Scopus (http://www.scopus.com). References of articles found were cross-checked where appropriate for missed publications. Manufacturers' and related websites were searched with Google Search (http://www.google.com.hk). A generic name for this class of materials, Hydraulic Silicate Cement (HSC), is proposed, and an outline reaction scheme has been deduced. HSC has distinct advantages apparent, including sealing, sterilizing, mineralizing, dentinogenic and osteogenic capacities, which research continues to demonstrate. However, ad hoc modifications have little supporting justification. While HSC has a definite place in dentistry, with few of the drawbacks associated with other materials, some improvements in handling and other properties are highly desirable, as are studies of the mechanisms of the several beneficial physiological effects. Reference to the extensive, but complex, literature on OPC may provide the necessary insight. Copyright © 2011 Academy of Dental Materials. Published by Elsevier Ltd. All rights reserved.

A new cement (CER; Cimento Endodôntico Rápido or fast endodontic cement) has been developed to improve handling properties. It is a formulation that has Portland cement in gel. However, there had not yet been any study evaluating its biologic properties. The purpose of this study was to evaluate the rat subcutaneous tissue response to CER and Angelus MTA. The materials were placed in polyethylene tubes and implanted into dorsal connective tissue of Wistar rats for 7, 30, and 60 days. The specimens were prepared to be stained with hematoxylin-eosin or von Kossa or not stained for polarized light. The presence of inflammation, predominant cell type, calcification, and thickness of fibrous connective tissue were recorded. Scores were defined as follows: 0, none or few inflammatory cells, no reaction; 1, 125 cells, severe reaction. Fibrous capsule was categorized as thin when thickness was 150 mum. Necrosis and formation of calcification were both recorded. Both materials Angelus MTA and CER caused moderate reactions at 7 days, which decreased with time. The response was similar to the control at 30 and 60 days with Angelus MTA and CER, characterized by organized connective tissue and presence of some chronic inflammatory cells. Mineralization and granulations birefringent to polarized light were observed with both materials. It was possible to conclude that CER was biocompatible and stimulated mineralization.

The aim of the present study was to assess, by means of Raman spectroscopy, the repair of complete surgical tibial fractures fixed with wire osteosynthesis or miniplates treated or not with infrared laser (λ780 nm) or infrared LED (λ850 +/- 10 nm) lights, 142.8 J/cm2 per treatment, associated or not to the use of mineral trioxide aggregate (MTA) cement. Surgical fractures were created on 36 rabbits and fixed with WO or miniplates and some groups were grafted with MTA. Irradiated groups received lights at every other day for 15 days and sacrifice occurred after 30 days. The results showed that only irradiation with either laser or LED influenced the peaks of phosphate ( 960 cm-1) and carbonated ( 1,070 cm-1) hydroxyapatite. Collagen peak (1,450 cm-1) was influenced by both the use of MTA and irradiation with either laser or LED. It is concluded that the use of either laser or LED phototherapy associated to MTA cement was efficacious on improving the repair of complete tibial fractures treated with wire osteosynthesis or miniplates.

Full Text Available The aim of this study was the comparative evaluation of inflammatory reactions and tissue responses to four growth factors, or mineral trioxide aggregate (MTA, or a zinc-oxide-eugenol-based cement (IRM as controls, when used for the repair of furcal perforations in dogs’ teeth. Results showed significantly higher inflammatory cell response in the transforming growth factorβ1 (TGFβ1 and zinc-oxide-eugenol-based cement (IRM groups and higher rates of epithelial proliferation in the TGFβ1, basic fibroblast growth factor (bFGF, and insulin growth factor-I (IGF-I groups compared to the MTA. Significantly higher rates of bone formation were found in the control groups compared to the osteogenic protein-1 (OP-1. Significantly higher rates of cementum formation were observed in the IGF-I and bFGF groups compared to the IRM. None of the biologically active molecules can be suggested for repairing furcal perforations, despite the fact that growth factors exerted a clear stimulatory effect on cementum formation and inhibited collagen capsule formation. MTA exhibited better results than the growth factors.

To evaluate nanoparticulate calcium carbonate (NPCC) using transmission electron microscopy and the effects of NPCC addition to MTA in regard to the setting time, dimensional change, compressive strength, solubility and pH. The experimental groups were G1 (MTA), G2 (MTA with 5% NPCC) and G3 (MTA with 10% NPCC). The tests followed ISO and ADA standards. The specimens in the dimensional change and compressive strength tests were measured immediately after setting, after 24 h and after 30 days. In the solubility test, rings filled with cement were weighed after setting and after 30 days. The pH was measured after 24 h and 30 days. The data were analysed with the ANOVA, Tukey's and Kruskal-Wallis tests (α = 5%). The setting time was reduced (P  G2 > G3). The solubility test revealed a difference amongst the groups when the specimens were hydrated: G2 > G1 > G3 and dehydrated: G3 > G2 > G1. The pH of the groups was similar at 24 h with higher values in each group after 30 days (P calcium carbonate had a cubic morphology with few impurities. The addition of nanoparticulate calcium carbonate to MTA accelerated the setting time, decreased compressive strength and, after 30 days, resulted in lower dimensional change (G2), higher solubility and a higher pH. © 2015 International Endodontic Journal.

This study evaluated and compared the pH, radiopacity, setting time, solubility, dimensional change, and compressive strength of ProRoot MTA (PMTA), ProRoot MTA (tooth colored formula) (WMTA), white Portland cement (WP), and ordinary Portland cement (OP). The results showed that PMTA and Portland cement have very similar physical properties. However, the radiopacity of Portland cement is much lower than that of PMTA. The compressive strength of PMTA was greater than Portland cement at 28 days. The major constituent of PMTA is Portland cement. Given the low cost of Portland cement and similar properties when compared to PMTA, it is reasonable to consider Portland cement as a possible substitute for PMTA in endodontic applications. However, industrially manufactured Portland cement is not approved currently for use in the United States and therefore no clinical recommendation can be made for its use in the human body. Further in vitro and in vivo tests, especially with regards its biocompatibility, should be conducted to ascertain if it meets the FDA requirements for use as a medical device.

Dental Stem Cell Migration on Pulp Ceiling Cavities Filled with MTA, Dentin Chips, or Bio-Oss

Directory of Open Access Journals (Sweden)

Stefania Lymperi

2015-01-01

Full Text Available MTA, Bio-Oss, and dentin chips have been successfully used in endodontics. The aim of this study was to assess the adhesion and migration of dental stem cells on human pulp ceiling cavities filled with these endodontic materials in an experimental model, which mimics the clinical conditions of regenerative endodontics. Cavities were formed, by a homemade mold, on untouched third molars, filled with endodontic materials, and observed with electron microscopy. Cells were seeded on cavities’ surface and their morphology and number were analysed. The phenomenon of tropism was assessed in a migration assay. All three materials demonstrated appropriate microstructures for cell attachment. Cells grew on all reagents, but they showed a differential morphology. Moreover, variations were observed when comparing cells numbers on cavity’s filling versus the surrounding dentine disc. The highest number of cells was recorded on dentin chips whereas the opposite was true for Bio-Oss. This was confirmed in the migration assay where a statistically significant lower number of cells migrated towards Bio-Oss as compared to MTA and dentin chips. This study highlights that MTA and dentin chips have a greater potential compared to Bio-Oss regarding the attraction of dental stem cells and are good candidates for bioengineered pulp regeneration.

A challenge to unqualified medical confidentiality.

Science.gov (United States)

Bozzo, Alexander

2018-04-01

Medical personnel sometimes face a seeming conflict between a duty to respect patient confidentiality and a duty to warn or protect endangered third parties. The conventional answer to dilemmas of this sort is that, in certain circumstances, medical professionals have an obligation to breach confidentiality. Kenneth Kipnis has argued, however, that the conventional wisdom on the nature of medical confidentiality is mistaken. Kipnis argues that the obligation to respect patient confidentiality is unqualified or absolute, since unqualified policies can save more lives in the long run. In this paper, I identify the form of Kipnis's argument and present a challenge to it. I conclude that, as matters stand now, a qualified confidentiality policy is the more rational choice. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

2011-01-01

Full Text Available BACKGROUND: Confidential unit exclusion remains a controversial strategy to reduce the residual risk of transfusion-transmitted infections. OBJECTIVE: This study aimed to analyze confidential unit exclusion from its development in a large institution in light of confidential donation confirmation. METHODS: Data of individuals who donated from October 1, 2008 to December 31, 2009 were analyzed in a case-control study. The serological results and sociodemographic characteristics of donors who did not confirm their donations were compared to those who did. Variables with p-values < 0.20 in univariate analysis were included in a logistic multivariate analysis. RESULTS: In the univariate analysis there was a statically significant association between positive serological results and response to confidential donation confirmation of "No". Donation type, (firsttime or return donor - OR 1.69, CI 1.37-2.09, gender (OR 1.66, CI 1.35-2.04, education level (OR 2.82, CI 2.30-3.47 and ethnic background (OR 0.67, CI 0.55-0.82 were included in the final logistic regression model. In all logistic regression models analyzed, the serological suitability and confidential donation confirmation were not found to be statistically associated. The adoption of new measures of clinical classification such as audiovisual touch-screen computer-assisted self-administered interviews might be more effective than confidential unit exclusion in the identification of donor risk behavior. The requirement that transfusion services continue to use confidential unit exclusion needs to be debated in countries where more specific and sensitive clinical and serological screening methods are available. CONCLUSION: Our findings suggest that there are not enough benefits to justify continued use of confidential donation confirmation in the analyzed institution.

Concurrently Deniable Group Key Agreement and Its Application to Privacy-Preserving VANETs

Full Text Available VANETs need secure communication. Authentication in VANETs resists the attack on the receipt of false information. Authenticated group key agreement (GKA is used to establish a confidential and authenticated communication channel for the multiple vehicles. However, authentication incurs privacy leakage, that is, by using digital signature. Therefore, the deniability is deserved for GKA (which is termed as DGKA due to the privacy protection. In the DGKA protocol, each participant interacts with intended partners to establish a common group session key. After this agreement session, each participant can not only be regarded as the intended sender but also deny that it has ever participated in this session. Therefore, under this established key, vehicles send confidential messages with authentication property and the deniability protects the vehicles privacy. We present a novel transformation from an unauthenticated group key agreement to a deniable (authenticated group key agreement without increasing communication round. Our full deniability is achieved even in the concurrent setting which suits the Internet environment. In addition, we design an authenticated and privacy-preserving communication protocol for VANETs by using the proposed deniable group key agreement.

A Comparative Study of Apical Healing of Open Apices Using MTA and Ca(OH2 Apical Plugs in Cats

Full Text Available Statement of problem: Endodontic treatment of necrotic teeth with open apices is a challenge. After ruling out surgery as a treatment scheme and introduction of the multivisit apexification which in turn had its disadvantages, apical plug seems to be a suitable substitute treatment plan for such cases. Apical plug makes the treatment through formation of a barrier against the obturating material in a single visit.Purpose: The purpose of this study was to compare histologically the periapical healing using MTA and calcium hydroxide apical plugs after intervals of 4 and 12 weeks in cats.Materials and Methods: In this clinical trial study 64 canines of 16 healthy and mature cats were divided into 3 groups after a periapical lesion formation by over instrumentation in the apical area with files up to no.120. The first group included 24 teeth on which MTA apical plug was applied. The second group included 24 teeth on which Ca (OH 2 apical plug was applied. In both groups the canals were filled with gutta percha and sealer. The third group included 16 control teeth whose canals were left empty after instrumentation and debridement. The access cavities of all teeth were sealed with varnish and amalgam and the vital perfusion of cats was performed in 4 and 12 week intervals. Statistical analysis was established by χ2 and independence test.Results: After 4 weeks, periapical healing in the first group was 90%, in the second group 80% and in the third group, it was only 12.5 %. After 12 weeks, periapical healing occurred in 100% of the MTA group, while it was 57.1% in the second and 40%in the third group .Generally, in the study of histological parameters of healing, no statistical significant difference was observed between the 2 experimental groups,although the MTA group results were much better than the Ca (OH 2 group especially at 12 weeks.Conclusion: The use of MTA apical plug is more effective than Ca (OH 2 in treatment of necrotic teeth with open

Gandolfi, Maria Giovanna; Taddei, Paola; Siboni, Francesco; Modena, Enrico; Ciapetti, Gabriela; Prati, Carlo

2011-07-01

An innovative light-curable calcium-silicate cement containing a HEMA-TEGDMA-based resin (lc-MTA) was designed to obtain a bioactive fast setting root-end filling and root repair material. lc-MTA was tested for setting time, solubility, water absorption, calcium release, alkalinizing activity (pH of soaking water), bioactivity (apatite-forming ability) and cell growth-proliferation. The apatite-forming ability was investigated by micro-Raman, ATR-FTIR and ESEM/EDX after immersion at 37°C for 1-28 days in DPBS or DMEM+FBS. The marginal adaptation of cement in root-end cavities of extracted teeth was assessed by ESEM/EDX, and the viability of Saos-2 cell on cements was evaluated. lc-MTA demonstrated a rapid setting time (2min), low solubility, high calcium release (150-200ppm) and alkalinizing power (pH 10-12). lc-MTA proved the formation of bone-like apatite spherulites just after 1 day. Apatite precipitates completely filled the interface porosities and created a perfect marginal adaptation. lc-MTA allowed Saos-2 cell viability and growth and no compromising toxicity was exerted. HEMA-TEGDMA creates a polymeric network able to stabilize the outer surface of the cement and a hydrophilic matrix permeable enough to allow water absorption. SiO(-)/Si-OH groups from the mineral particles induce heterogeneous nucleation of apatite by sorption of calcium and phosphate ions. Oxygen-containing groups from poly-HEMA-TEGDMA provide additional apatite nucleating sites through the formation of calcium chelates. The strong novelty was that the combination of a hydraulic calcium-silicate powder and a poly-HEMA-TEGDMA hydrophilic resin creates the conditions (calcium release and functional groups able to chelate Ca ions) for a bioactive fast setting light-curable material for clinical applications in dental and maxillofacial surgery. The first and unique/exclusive light-curable calcium-silicate MTA cement for endodontics and root-end application was created, with a potential

Five disc-shaped specimens (10 x 1 mm were fabricated from each material, according to the ISO 6876/2001 standard. After setting of the materials, radiographs were taken using occlusal film and a graduated aluminum stepwedge varying from 2 to 16 mm in thickness. The dental X-ray unit (GE1000 was set at 50 kVp, 10 mA, 18 pulses/s and distance of 33.5 cm. The radiographs were digitized and the radiopacity compared to that of the aluminum stepwedge using VIXWIN-2000 software (Gendex. The data (mmAl were analyzed statistically by ANOVA and Tukey's test at the 5% significance level. Epiphany and Intrafill presented the highest radiopacity values (8.3 mmAl and 7.5 mmAl respectively, p < 0.05 followed by Sealer 26 (6.3 mmAl, Sealapex (6.1 mmAl and Endo CPM Sealer (6 mmAl. Acroseal was the least radiopaque material (4 mmAl, p < 0.05. In conclusion, the calcium hydroxide- and MTA-containing root canal sealers had different radiopacities. However, all materials presented radiopacity values above the minimum recommended by the ISO standard.

An in vitro microbial leakage test (MLT) with a split chamber was used in this study. A mixture of facultative bacteria and one yeast (S. aureus+E. faecalis+P. aeruginosa+B. subtilis+C. albicans) was placed in the upper chamber and it could only reach the lower chamber containing Brain Heart Infusion broth by way of leakage through the root-end filling. Microbial leakage was observed daily for 60 days. Sixty maxillary anterior human teeth were randomly assigned to different groups--MTA and PC (gray and white), Sealapex+zinc oxide and ZOE, control groups and subgroups to evaluate the influence of EDTA for smear layer removal. These materials were further evaluated by an agar diffusion test (ADT) to verify their antimicrobial efficacy. Data were analyzed statistically by Kruskal-Wallis and Mann-Whitney test. In the MLT, Sealapex+zinc oxide and ZOE did not show evidence of microbial leakage over the 60-day experimental period. The other materials showed leakage from the 15th day. The presence of smear layer influenced microbial leakage. Microbial inhibition zones were not observed in all samples tested by ADT. Sealapex+zinc oxide and ZOE did not show microbial leakage over the experimental period, whereas it was verified within 15 to 45 days in MTA and Portland cement.

To evaluate the biocompatibility and the setting time of Portland cement clinker with or without 2% or 5% calcium sulfate and MTA-CPM. Twenty-four mice (Rattus norvegicus) received subcutaneously polyethylene tubes filled with Portland cement clinker with or without 2% or 5% calcium sulfate and MTA. After 15, 30 and 60 days of implantation, the animals were killed and specimens were prepared for microscopic analysis. For evaluation of the setting time, each material was analyzed using Gilmore needles weighing 113.5 g and 456.5 g, according to the ASTM specification Number C266-08 guideline. Data were analyzed by ANOVA and Tukey's test for setting time and Kruskal-Wallis and Dunn test for biocompatibility at 5% significance level. Histologic observation showed no statistically significant difference of biocompatibility (p>0.05) among the materials in the subcutaneous tissues. For the setting time, clinker without calcium sulfate showed the shortest initial and final setting times (6.18 s/21.48 s), followed by clinker with 2% calcium sulfate (9.22 s/25.33 s), clinker with 5% calcium sulfate (10.06 s/42.46 s) and MTA (15.01 s/42.46 s). All the tested materials showed biocompatibility and the calcium sulfate absence shortened the initial and final setting times of the white Portland cement clinker.

Computer Security: Printing confidentially

Have you ever hesitated to print a confidential document using CERN printers? Or perhaps you have rushed quickly to the printer after hitting the “print” button in order to avoid someone else getting hold of and reading your document? These times are over now with the new printing infrastructure!   Indeed, many of us regularly print out confidential documents like our salary slips, MARS forms, tendering documents and drafts of preliminary papers. The upcoming CERN data protection policy will require all of us to respect the confidentiality of such documents and, as the word “confidential” implies, access to “confidential” or sensitive documents will be tightly controlled. What can we do about the public printers located in many buildings, floors and shared spaces - accessible not only to CERN staff and users but also to visitors and guests? Some printers are located in the vicinity of restaurants, cafeterias or close to paths taken b...

During the last two decades EAPs have offered employees confidential assessment, counseling, and referral. Many occupational health nurses have taken on the role of EAP professional or function as the liaison between the EAP counselor and the employee. The occupational health nurse involved in any EAP issue must adhere to the standards of confidentiality. The federal and state laws, company policy, and professional codes of ethics regarding these clients must be clearly understood, especially related to the issue of confidentiality.

A novel, highly conserved metallothionein family in basidiomycete fungi and characterization of two representative SlMTa and SlMTb genes in the ectomycorrhizal fungus Suillus luteus.

The basidiomycete Suillus luteus is an important member of the ectomycorrhizal community that thrives in heavy metal polluted soils covered with pioneer pine forests. This study aimed to identify potential heavy metal chelators in S. luteus. Two metallothionein (MT) coding genes, SlMTa and SlMTb, were identified. When heterologously expressed in yeast, both SlMTa and SlMTb can rescue the Cu sensitive mutant from Cu toxicity. In S. luteus, transcription of both SlMTa and SlMTb is induced by Cu but not Cd or Zn. Several putative Cu-sensing and metal-response elements are present in the promoter sequences. These results indicate that SlMTa and SlMTb function as Cu-thioneins. Homologs of the S. luteus MTs are present in 49 species belonging to 10 different orders of the subphylum Agaricomycotina and are remarkably conserved. The length of the proteins, number and distribution of cysteine residues indicate a novel family of fungal MTs. The ubiquitous and highly conserved features of these MTs suggest that they are important for basic cellular functions in species in the subphylum Agaricomycotina. © 2017 Society for Applied Microbiology and John Wiley & Sons Ltd.

Law and ethics in conflict over confidentiality?

Science.gov (United States)

Dickens, B M; Cook, R J

2000-09-01

Ethical principles that require the preservation of patients' confidential information are reinforced by principles found in several areas of law, such as law on contracts, negligence, defamation and fiduciary duty. However, laws sometimes compel disclosures of medical confidences, and more often may justify or excuse disclosures. Legally contentious issues concern patients' confidences regarding possible unlawful conduct, such as pregnancy termination, and the risk of spread of HIV and other infections. This article reviews the various legal bases of the duty of confidentiality, and legal challenges to the ethical obligation of non-disclosure. It addresses the justifications and limits of exchange of patients' health information among healthcare professionals and trainees, and considers legally recognized limits of confidential duties, and the scope of legitimate disclosure. An underlying theme is how to determine whether physicians are ethically justified in employing the discretion the law sometimes affords them to breach patients' expectations of confidentiality.

Mineral Trioxide Aggregate (MTA direct pulp capping: 10 years clinical results

Directory of Open Access Journals (Sweden)

Lucio Daniele

2017-06-01

After 10-years follow-up period, 6 out of 80 teeth required an endodontic treatment, we did not find an increase of pulp calcifications, root resorptions, endodontic lesions. All teeth still alive have responded positively to the cold-temperature test. The three lesions had disappeared at the last X-ray control. All four symptomatic teeth preserved their pulp vitality. The successful treatment rate was 92.5%. Direct pulp capping with MTA can be considered an effective treatment of exposure due to tooth decay and can be considered a valid treatment option for teeth with a diagnosis of not-severe reversible pulpitis.

Is patient confidentiality compromised with the electronic health record?: a position paper.

Science.gov (United States)

Wallace, Ilse M

2015-02-01

In order for electronic health records to fulfill their expected benefits, protection of privacy of patient information is key. Lack of trust in confidentiality can lead to reluctance in disclosing all relevant information, which could have grave consequences. This position paper contemplates whether patient confidentiality is compromised by electronic health records. The position that confidentiality is compromised was supported by the four bioethical principles and argued that despite laws and various safeguards to protect patients' confidentiality, numerous data breaches have occurred. The position that confidentiality is not compromised was supported by virtue ethics and a utilitarian viewpoint and argued that safeguards keep information confidential and the public feels relatively safe with the electronic health record. The article concludes with an ethically superior position that confidentiality is compromised with the electronic health record. Although organizational and governmental ways of enhancing the confidentiality of patient information within the electronic health record facilitate confidentiality, the ultimate responsibility of maintaining confidentiality rests with the individual end-users and their ethical code of conduct. The American Nurses Association Code of Ethics for nurses calls for nurses to be watchful with data security in electronic communications.

We report management of a failed revascularization/revitalization case, which could be due to inadequate removal of biofilm and bacteria in dentinal tubules. The use of an apical matrix barrier in form of a platelet-rich fibrin (PRF) membrane for stabilization of MTA in root end apexification procedure is described. The canal was cleansed of old MTA present in the cervical third using H files, irrigated using saline and finally irrigated with 2.5% NaOCl and saline. To obtain canal disinfection, calcium hydroxide paste was temporized in the canal. In subsequent appointments, PRF was placed at the root tip followed by 5-mm apical plug with mineral trioxide aggregate. One week later, the root canal was obturated with thermoplasticized gutta-percha. A 6-month and a 2-year follow ups showed reduction of periapical radiolucency and adequately functional tooth. One-visit apexification techniques provide an alternative treatment for failed revascularization cases. Follow up confirmed complete healing periradicularly. Apexification in one step using an apical barrier of PRF and a plug of MTA can be considered a predictable treatment and may be an alternative to long-term revascularization failures. © 2015 John Wiley & Sons A/S.

Can you keep a secret? Confidentiality in psychotherapy.

Science.gov (United States)

Younggren, Jeffrey N; Harris, Eric A

2008-05-01

Confidentiality is the secret-keeping duty that arises from the establishment of the professional relationship psychologists develop with their clients. It is a duty created by the professional relationship, it is set forth in the American Psychological Association's (2002) Ethical Principles and Code of Conduct, and it is codified in many state regulations. However, the difference between confidentiality and legal privilege; how, why, and when it can be violated; and the reasons for so doing are not well understood by many practitioners. While on the surface confidentiality might seem to be an easy concept to apply to professional practice, in fact it is quite complex and filled with exceptions that frequently differ from circumstance to circumstance and from state to state. A lack of respect for and a lack of familiarity with the significance of these exceptions could have dire professional consequences. This article reviews the ethical imperative of confidentiality and then provides examples of legal cases that help to better understand its complexity. Then, we offer strategies designed to help metal health practitioners when they are confronted with questions regarding confidentiality and privilege.

Curcumin increases the sensitivity of Paclitaxel-resistant NSCLC cells to Paclitaxel through microRNA-30c-mediated MTA1 reduction.

Non-small-cell lung cancer is one of the most lethal cancers in the worldwide. Although Paclitaxel-based combinational therapies have long been used as a standard treatment in aggressive non-small-cell lung cancers, Paclitaxel resistance emerges as a major clinical problem. It has been demonstrated that Curcumin from Curcuma longa as a traditional Chinese medicine can inhibit cancer cell proliferation. However, the role of Curcumin in Paclitaxel-resistant non-small-cell lung cancer cells is not clear. In this study, we investigated the effect of Curcumin on the Paclitaxel-resistant non-small-cell lung cancer cells and found that Curcumin treatment markedly increased the sensitivity of Paclitaxel-resistant non-small-cell lung cancer cells to Paclitaxel. Mechanically, the study revealed that Curcumin could reduce the expression of metastasis-associated gene 1 (MTA1) gene through upregulation of microRNA-30c in Paclitaxel-resistant non-small-cell lung cancer cells. During the course, MTA1 reduction sensitized Paclitaxel-resistant non-small-cell lung cancer cells and enhanced the effect of Paclitaxel. Taken together, our studies indicate that Curcumin increases the sensitivity of Paclitaxel-resistant non-small-cell lung cancer cells to Paclitaxel through microRNA-30c-mediated MTA1 reduction. Curcumin might be a potential adjuvant for non-small-cell lung cancer patients during Paclitaxel treatment.

Protecting Privacy and Confidentiality in Environmental Health Research.

Science.gov (United States)

Resnik, David B

2010-01-01

Environmental health researchers often need to make difficult decisions on how to protect privacy and confidentiality when they conduct research in the home or workplace. These dilemmas are different from those normally encountered in clinical research. Although protecting privacy and confidentiality is one of the most important principles of research involving human subjects, it can be overridden to prevent imminent harm to individuals or if required by law. Investigators should carefully consider the facts and circumstances and use good judgment when deciding whether to breach privacy or confidentiality.

Physician Knowledge and Attitudes around Confidential Care for Minor Patients.

Science.gov (United States)

Riley, Margaret; Ahmed, Sana; Reed, Barbara D; Quint, Elisabeth H

2015-08-01

Minor adolescent patients have a legal right to access certain medical services confidentially without parental consent or notification. We sought to assess physicians' knowledge of these laws, attitudes around the provision of confidential care to minors, and barriers to providing confidential care. An anonymous online survey was sent to physicians in the Departments of Family Medicine, Internal Medicine-Pediatrics, Obstetrics/Gynecology, and Pediatrics at the University of Michigan. Response rate was 40% (259/650). The majority of physicians felt comfortable addressing sexual health, mental health, and substance use with adolescent patients. On average, physicians answered just over half of the legal knowledge questions correctly (mean 56.6% ± 16.7%). The majority of physicians approved of laws allowing minors to consent for confidential care (90.8% ± 1.7% approval), while substantially fewer (45.1% ± 4.5%) approved of laws allowing parental notification of this care at the physician's discretion. Most physicians agreed that assured access to confidential care should be a right for adolescents. After taking the survey most physicians (76.6%) felt they needed additional training on confidentiality laws. The provision of confidential care to minors was perceived to be most inhibited by insurance issues, parental concerns/relationships with the family, and issues with the electronic medical record. Physicians are comfortable discussing sensitive issues with adolescents and generally approve of minor consent laws, but lack knowledge about what services a minor can access confidentially. Further research is needed to assess best methods to educate physicians about minors' legal rights to confidential healthcare services.

Breaching confidentiality: medical mandatory reporting laws in Iran.

Milanifar, Alireza; Larijani, Bagher; Paykarzadeh, Parvaneh; Ashtari, Golanna; Mehdi Akhondi, Mohammad

2014-01-01

Medical ethics is a realm where four important subjects of philosophy, medicine, theology and law are covered. Physicians and philosophers cooperation in this area will have great efficiency in the respective ethical rules formation. In addition to respect the autonomy of the patient, physician's obligation is to ensure that the medical intervention has benefit for the patient and the harm is minimal. There is an obvious conflict between duty of confidentiality and duty of mandatory reporting. Professional confidentiality is one of the basic components in building a constant physician-patient relationship which nowadays, beside the novelty, it is the subject of discussion. Legal obligation of confidentiality is not absolute. In physician-patient relationship, keeping patient's secrets and maintaining confidentiality is a legal and ethical duty, and disclosure of such secrets is mainly through specific statutes. Thus, there are a number of situations where breach of confidentiality is permitted in different legal systems. One of the situations where breaching confidentiality is permitted is the medical mandatory reporting to the relevant authority which is in accordance with many countries' legal systems. Some situations are considered in many countries legal systems' such as notification of births and deaths, infectious diseases, child abuse, sport and relevant events, medical errors, drug side effects and dangerous pregnancies. In this paper, we will examine and discuss medical mandatory reporting and its ethical and legal aspects in the judicial and legal system of Iran and few other countries. Finally we will suggest making Medical Mandatory Reporting Law in Iran.

2016-01-01

We study how to enable arbitrary randomized algorithms in Byzantine fault-tolerant (BFT) settings. We formalize a randomized BFT protocol and provide a simple and efficient construction that can be built on any existing BFT protocols while adding practically no overhead. We go one step further to revisit a confidential BFT protocol (Yin et al., SOSP '03). We show that their scheme is potentially susceptible to safety and confidentiality attacks. We then present a new protocol that is secure in the stronger model we formalize, by extending the idea of a randomized BFT protocol. Our protocol uses only efficient symmetric cryptography, while Yin et al.'s uses costly threshold signatures. We implemented and evaluated our protocols on microbenchmarks and real-world use cases. We show that our randomized BFT protocol is as efficient as conventional BFT protocols, and our confidential BFT protocol is two to three orders of magnitude faster than Yin et al.'s, which is less secure than ours.

Protecting confidentiality rights: the need for an ethical practice model.

Science.gov (United States)

Fisher, Mary Alice

2008-01-01

All psychologists must uphold the same ethical standards about confidentiality even though each state imposes different legal limits on their ability to protect clients' confidences. The resulting ethical-legal confusion is exacerbated by legally based confidentiality training that treats legal exceptions as if they were the rule and fosters the impression that attorneys are now the only real experts about this aspect of practice. This article provides an ethics-based confidentiality practice model that clarifies the ethical rule and puts its legal exceptions into ethical perspective. Like the Confidentiality section of the American Psychological Association's (2002) Ethical Principles of Psychologists and Code of Conduct, this outline would apply to all psychologists regardless of state laws, but the details of its implementation would vary according to role and setting. It can be used as a universal training outline, a consultation and supervision tool, a guide to professional practice, and a basis for clearer ongoing conversation about the ethics of "conditional confidentiality." Psychologists can use this practice model to regain their status as experts about the confidentiality ethics of their own profession. PsycINFO Database Record (c) 2008 APA, all rights reserved.

Genetic secrets: Protecting privacy and confidentiality in the genetic era

Energy Technology Data Exchange (ETDEWEB)

Rothstein, M.A. [ed.

1998-07-01

Few developments are likely to affect human beings more profoundly in the long run than the discoveries resulting from advances in modern genetics. Although the developments in genetic technology promise to provide many additional benefits, their application to genetic screening poses ethical, social, and legal questions, many of which are rooted in issues of privacy and confidentiality. The ethical, practical, and legal ramifications of these and related questions are explored in depth. The broad range of topics includes: the privacy and confidentiality of genetic information; the challenges to privacy and confidentiality that may be projected to result from the emerging genetic technologies; the role of informed consent in protecting the confidentiality of genetic information in the clinical setting; the potential uses of genetic information by third parties; the implications of changes in the health care delivery system for privacy and confidentiality; relevant national and international developments in public policies, professional standards, and laws; recommendations; and the identification of research needs.

Utilities have become concerned that their competitors will desire access to energy-related data--including energy-efficiency data collected by utilities from their energy- efficiency programs--that they may regard as proprietary or confidential. In the future, disputes about confidentiality may focus more on costs and market information (as well as energy use and load data) than on energy-efficiency data per se. So far, the discussion has been limited to ratepayer-funded data. Consequently, many utilities are now requesting that the data (including evaluation data) they submit to their utility regulatory commissions remain confidential. Withholding utility information from the public is likely to harm the evaluation community that depends on the free flow of information for improving the practice of evaluation as well as for disseminating the lessons learned from particular program evaluations. Confidentiality will also have significant policy implications. In response to these concerns, in late 1995 and early 1996, we conducted a survey of state public utility commissions (PUCs) in the U.S. to assess: (1) the relative importance of the issue of confidential data in the regulatory arena; (2) the regulatory response to utility requests for confidentiality (e.g., formal policies, guidelines, rules and procedures, and decisions); and (3) the type of data filed as confidential with PUCS. We focus on the first two objectives of this study. In addition to our interviews, we reviewed selected state statutes, judicial and PUC decisions, rules and procedures, protective orders, and interim policy documents. Evaluators need to understand the context of confidentiality as well as the response of the regulatory commissions to confidentiality, because evaluators will need to adapt to a new environment where energy-related data and information may be harder to obtain and distribute. We propose that regulators conduct the following activities as soon as possible: 1. Assess

Improving Individual Acceptance of Health Clouds through Confidentiality Assurance.

Ermakova, Tatiana; Fabian, Benjamin; Zarnekow, Rüdiger

2016-10-26

Cloud computing promises to essentially improve healthcare delivery performance. However, shifting sensitive medical records to third-party cloud providers could create an adoption hurdle because of security and privacy concerns. This study examines the effect of confidentiality assurance in a cloud-computing environment on individuals' willingness to accept the infrastructure for inter-organizational sharing of medical data. We empirically investigate our research question by a survey with over 260 full responses. For the setting with a high confidentiality assurance, we base on a recent multi-cloud architecture which provides very high confidentiality assurance through a secret-sharing mechanism: Health information is cryptographically encoded and distributed in a way that no single and no small group of cloud providers is able to decode it. Our results indicate the importance of confidentiality assurance in individuals' acceptance of health clouds for sensitive medical data. Specifically, this finding holds for a variety of practically relevant circumstances, i.e., in the absence and despite the presence of conventional offline alternatives and along with pseudonymization. On the other hand, we do not find support for the effect of confidentiality assurance in individuals' acceptance of health clouds for non-sensitive medical data. These results could support the process of privacy engineering for health-cloud solutions.

Computer Security: confidentiality is everybody’s business

CERN Multimedia

Stefan Lueders, Computer Security Team

2015-01-01

Recently, a zip file with confidential information was mistakenly made public on one of CERN’s websites. Although the file was only intended for members of an internal committee, when placing it onto the CERN website, someone made a mistake when setting the access permissions and, thus, made the file accessible to everyone visiting the site!   Unfortunately, this is but one example of such mistakes. We have seen other documents made accessible to a much wider audience than originally intended… CERN takes serious measures to ensure the confidentiality of data. Confidential or “sensitive” documents (following the nomenclature set out in the CERN Data Protection Policy) deserve professional handling and access protections given only to the people who really need to access them. As such, they must not be widely circulated as attachments in e-mails and, most definitely, must not be stored on random public websites for the sole purpose of shari...

To evaluate participants' perceptions about frequent use and reasons for substance use (SU) in the qualitative interview study, an add-on to the multimodal treatment study of ADHD (MTA). Using the longitudinal MTA database, 39 ADHD cases and 19 peers with Persistent SU, and 86 ADHD cases and 39 peers without Persistent SU were identified and recruited. In adulthood, an open-ended interview was administered, and SU excerpts were indexed and classified to create subtopics (frequent use and reasons for use of alcohol, marijuana, and other drugs). For marijuana, the Persistent compared with Nonpersistent SU group had a significantly higher percentage of participants describing frequent use and giving reasons for use, and the ADHD group compared with the group of peers had a significantly higher percentage giving "stability" as a reason for use. Motivations for persistent marijuana use may differ for adults with and without a history of ADHD.

Clinically impairing irritability affects 25% to 45% of children with attention-deficit/hyperactivity disorder (ADHD); yet, we know little about what interventions are effective in treating children with ADHD and co-occurring irritability. We used data from the Multimodal Treatment Study of Children With ADHD (MTA) to address 3 aims: to establish whether irritability in children with ADHD can be distinguished from other symptoms of oppositional defiant disorder (ODD); to examine whether ADHD treatment is effective in treating irritability; and to examine how irritability influences ADHD treatment outcomes. Secondary analyses of data from the MTA included multivariate analyses, and intent-to-treat random-effects regression models were used. Irritability was separable from other ODD symptoms. For treating irritability, systematic stimulant treatment was superior to behavioral management but not to routine community care; a combination of stimulants and behavioral treatment was superior to community care and to behavioral treatment alone, but not to medication alone. Irritability did not moderate the impact of treatment on parent- and teacher-reported ADHD symptoms in any of the 4 treatment groups. Treatments targeting ADHD symptoms are helpful for improving irritability in children with ADHD. Moreover, irritability does not appear to influence the response to treatment of ADHD.

Independent consultants : fiduciary duties, trade secrets and confidential information

International Nuclear Information System (INIS)

Fraser, B.; Wilhelmson, M.

1999-01-01

Because of cutbacks and downsizing within the petroleum industry, it has become one of the largest users of contract personnel to provide services that were previously provided by senior levels of management. This paper explored the application of common law fiduciary duties and the duty of confidence to the independent workforce. It examined to what extent fiduciary duties apply to independent consultants and the best way for the employer to protect itself from the potential misuse of confidential information. Part 1 of the paper described fiduciary duties. A fiduciary relationship was described as one that possesses the following three characteristics: (1) the fiduciary has scope for the exercise of some discretion of power, (2) the fiduciary can unilaterally exercise that power to affect the beneficiary's practical interests, and (3) the beneficiary is peculiarly vulnerable to the fiduciary holding the discretion of power. Three examples of how the courts treated some arguments regarding fiduciaries were presented. Part 2 of this paper discussed how trade secrets and confidential information should be handled. It was explained, that regardless of fiduciary duties, the unauthorized use of confidential information by an independent contractor can give rise to liability and an award of damages by the courts. Some examples where the Supreme Court of Canada found breach of confidence by a party were presented. Information communicated from an employer to an employee can be divided into the following three categories: (1) publicly accessible and not confidential, (2) confidential and must be treated as such while an employee is employed, but if learned becomes part of the employees skill and knowledge, and (3) specific confidential trade secrets that cannot lawfully be used for anyone's benefit but the employer's. Issues regarding defining rights and obligations by contract were also discussed

Fayazi, Sara; Ostad, Seyed Nasser; Razmi, Hasan

2011-01-01

Today many materials have been introduced for root-end filling materials. One of them is mineral trioxide aggregate (MTA) that is mentioned as a gold standard. The purpose of this in vitro study was to evaluate the reaction of human periodontal ligament fibroblasts to the root-end filling materials, such as ProRoot MTA, Portland cement, and amalgam. Eight impacted teeth were extracted in aseptic condition. The tissues around the roots were used to obtain fibroblast cells. After cell proliferation, they were cultured in the chamber slides and the extracts of the materials were added to the wells. Immunocytochemical method for measuring the expression of Fibronectin, collagen I and transforming growth factor beta (TGF®) was performed by Olysia Bioreport Imaging Software. The results were analyzed by SPSS 13.0 and Tukey post hoc test with PPortland cement group showed the most expression of collagen significantly and after 1 week, Portland cement and MTA groups had the most expression of collagen but there was no significant difference between these 2 groups. After 1 week, the Portland cement group demonstrated a higher amount of TGF® and fibronectin. The results suggest that Portland cement can be used as a less expensive root filling material with low toxicity. It has better effects than amalgam on the fibroblasts.

We studied peaks of calcium hydroxyapatite (CHA) and protein and lipid CH groups in defects grafted with mineral trioxide aggregate (MTA) treated or not with LED irradiation, bone morphogenetic proteins and guided bone regeneration. A total of 90 rats were divided into ten groups each of which was subdivided into three subgroups (evaluated at 15, 21 and 30 days after surgery). Defects were irradiated with LED light (wavelength 850 ± 10 nm) at 48-h intervals for 15 days. Raman readings were taken at the surface of the defects. There were no statistically significant differences in the CHA peaks among the nonirradiated defects at any of the experimental time-points. On the other hand, there were significant differences between the defects filled with blood clot and the irradiated defects at all time-points (p Raman spectral analysis indicate that infrared LED light irradiation improves the deposition of CHA in healing bone grafted or not with MTA.

Genetic secrets: Protecting privacy and confidentiality in the genetic era. Final report

Energy Technology Data Exchange (ETDEWEB)

Rothstein, M.A. [ed.

1998-09-01

Few developments are likely to affect human beings more profoundly in the long run than the discoveries resulting from advances in modern genetics. Although the developments in genetic technology promise to provide many additional benefits, their application to genetic screening poses ethical, social, and legal questions, many of which are rooted in issues of privacy and confidentiality. The ethical, practical, and legal ramifications of these and related questions are explored in depth. The broad range of topics includes: the privacy and confidentiality of genetic information; the challenges to privacy and confidentiality that may be projected to result from the emerging genetic technologies; the role of informed consent in protecting the confidentiality of genetic information in the clinical setting; the potential uses of genetic information by third parties; the implications of changes in the health care delivery system for privacy and confidentiality; relevant national and international developments in public policies, professional standards, and laws; recommendations; and the identification of research needs.

Conflicting duties over confidentiality in Argentina and Peru.

Science.gov (United States)

Cavallo, Mercedes

2011-02-01

The medical duty of confidentiality represents a key element for the provision of reproductive and sexual health services. In some Latin American countries, such as Argentina and Peru, the legal systems impose—or are interpreted as imposing—on health professionals the duty of confidentiality, but also the duty to report the commission of a public order offense that they know about owing to the practicing of their profession. In these countries, the conflicting duties and the criminalization of abortion cause severe public health and human rights problems when health professionals assist their patients for post-abortion treatment. Typically, patients are deterred from seeking prompt medical care, and their privacy, autonomy, and dignity are violated. A 2010 ruling from the Supreme Court of Argentina and a 2004 ruling from the Inter-American Court of Human Rights emerge as important instruments that grant a more adequate protection of medical confidentiality. © 2010 International Federation of Gynecology and Obstetrics.

Timar, J.; Elekes, Z. [Atomki, Debrecen (Hungary)

2013-08-15

The center at the Institute for Nuclear Research (MTA Atomki) consists of two evaluators who devote altogether 0.5 FTE to mass-chain evaluation work. We have been working on mass-chain evaluation since 2009. Until now we have been working on mass chains that were temporarily assigned to us. Now we have permanent responsibilities, which are the A=101-105 mass chains. Our evaluation work is funded mainly by MTA Atomki, but we have also received considerable financial support from IAEA through Research Contract No. 15902/R0, and from the McMaster University. Besides financial supports, we received great help from Balraj Singh to start and build up our evaluation work. Mass-chain evaluation in the 2011-2012 period: In the covered period, we evaluated the A=128, A=129 and A=46 mass chains. 1) The evaluation of the A=129 mass chain had started in the previous period, however due to appearance of new important published and unpublished data after the review of the NDS manuscript, we decided to include them into the new evaluation. It is in post review status. 2) The evaluation of the A=128 mass chain has been finished, and it has been submitted to NNDC. It is in pre review status. 3) The evaluation of the A=46 mass chain is still in progress, but it is close to be finished and to be submitted to NNDC. Plans for the next period: The group plans to continue the mass-chain evaluation on a basis of about one mass chain per year. For the next period we plan to finish and publish the A=129, 128 and 46 mass chains. Also, as the mass chains of A=105 and A=101, from our permanently assigned mass chains, has been updated last in 2004 and 2006, respectively, we plan to evaluate these two mass chains starting with A=105.

Participants' safety versus confidentiality: A case study of HIV research.

Science.gov (United States)

Leyva-Moral, Juan Manuel; Feijoo-Cid, Maria

2017-05-01

Background When conducting qualitative research, participants usually share lots of personal and private information with the researcher. As researchers, we must preserve participants' identity and confidentiality of the data. Objective To critically analyze an ethical conflict encountered regarding confidentiality when doing qualitative research. Research design Case study. Findings and discussion one of the participants in a study aiming to explain the meaning of living with HIV verbalized his imminent intention to commit suicide because of stigma of other social problems arising from living with HIV. Given the life-threatening situation, the commitment related to not disclosing the participant's identity and/or the content of the interview had to be broken. To avoid or prevent suicide, the therapist in charge of the case was properly informed about the participant's intentions. One important question arises from this case: was it ethically appropriate to break the confidentiality commitment? Conclusion confidentiality could be broken if a life-threatening event is identified during data collection and participants must know that. This has to be clearly stated in the informed consent form.

To design and evaluate the usage of an adolescent patient portal specifically adapted for adolescent health care needs that also satisfied institutional meaningful use guidelines regarding electronic health records. Key stakeholders at one academic health care center adopted an online portal and opted to designate a patient portal specifically for adolescents to maximize confidentiality in compliance with state privacy laws. This study analyzed aggregate electronic health record data of adolescents' (ages 12-17.9 years) uptake, usage, and functionality of this portal and compared it to parent portal usage for younger children (ages 0-11 years). Differences in means were calculated using paired t tests. The portal was used similarly between parents of young children and adolescents, with almost 1,000 enrollees in each group from September 1, 2012 to March 31, 2015. There were no gender differences in enrollment. Adolescents were less likely than parents of younger children to review appointments (73% vs. 85%), laboratory tests (67% vs. 79%), problem lists (40% vs. 78%), or allergies (45% vs. 77%, all p values adolescents sent 1,397 confidential messages. Institutional decisions for implementing meaningful use requirements can align with goals of adolescent health. Patient portals can enhance adolescent health care quality and adolescents readily use a confidential portal. Implementation of meaningful use requirements should be checked against adolescent health care needs to maximize confidentiality and promote health communication.

Shenoy, Akhil; Appel, Jacob M

2017-04-01

Electronic health records (EHRs) offer significant advantages over paper charts, such as ease of portability, facilitated communication, and a decreased risk of medical errors; however, important ethical concerns related to patient confidentiality remain. Although legal protections have been implemented, in practice, EHRs may be still prone to breaches that threaten patient privacy. Potential safeguards are essential, and have been implemented especially in sensitive areas such as mental illness, substance abuse, and sexual health. Features of one institutional model are described that may illustrate the efforts to both ensure adequate transparency and ensure patient confidentiality. Trust and the therapeutic alliance are critical to the provider-patient relationship and quality healthcare services. All of the benefits of an EHR are only possible if patients retain confidence in the security and accuracy of their medical records.

This study evaluated the sealing ability of apical plugs fabricated with gray MTA Angelus sealer, CPM TM sealer and MBPc sealer. The root canals of 98 extracted single-rooted human teeth were instrumented with #5 to #1 Gates Glidden drills according to the crown-down technique until the #1 drill could pass through the apical foramen. The specimens were then prepared with K-files, starting with an ISO 50 until an ISO 90 could be visualized 1 mm beyond the apex. After root canal preparation, the external surface of each root was rendered impermeable and roots were assigned to 3 experimental groups (n = 30), which received a 5-mm thick apical plug of gray MTA Angelus, CPM and MBPc, and two control groups (n=4). The remaining portion of the canal in the experimental groups was filled by the lateral condensation technique. The teeth of each group, properly identified, were fixed on utility wax by their crowns and were placed in plastic flasks, leaving the apex free and facing upward. The flasks were filled with 0.2% Rhodamine B solution, pH 7.0, so as to completely cover the root apex of all teeth. The sealing ability was analyzed by measuring 0.2% Rhodamine B leakage after all groups had been maintained in this solution for 48 hours. Data were analyzed statistically by Kruskal-Wallis test and Dunn test with a=5%. The results showed that, among the tested materials used for fabrication of apical plugs, MBPc sealer had the least amount of leakage with statistically significant difference (p<0.05).

THE PRINCIPLE OF CONFIDENTIALITY IN ARBITRATION. APPLICATION AND LIMITATIONS OF THE PRINCIPLE

Directory of Open Access Journals (Sweden)

Bazil Oglindă

2015-11-01

Full Text Available Over the years, arbitration has grown to be the preferred means of dispute resolution by commercial entities. One of the benefits that build the attraction for this system of dispute resolution was the principle of confidentiality. One issue that needs to be analyzed is about the reasons why confidentiality is so important in business. Confidentiality is a principle largely embraced in arbitration, but, as we will see, the principle is not an absolute one. There are a set of questions that needs to be answer to, like: Who is bound by the duty of confidentiality? Does this refer only to the parties or does it expands to other actors involved in the arbitral proceedings? What happens with the obligation of confidentiality when issues are brought before a court, taking in account the principle of open justice? We will see that in some countries are procedural laws allowing the courts to order an arbitration claim to be heard in public or in private. Another important aspect that has arisen in the last period is regarding the public policy and the protection of public interest as a limitation to confidentiality of arbitration. This is a sensitive matter especially when one of the parties is a state or a state entity. This study aims to explore the principle of confidentiality in arbitration by focusing on its domain and on its limits, both from the comparative approach and from the Romanian approach. Knowing all this aspects, we will realize the importance of having professional counseling when drafting an arbitration clause and how this can be the missing puzzle piece of your business.

The study aims to explore within the community pharmacy practice context the views of mental health stakeholders on: (1) current and past experiences of privacy, confidentiality and support; and (2) expectations and needs in relation to privacy and confidentiality. In-depth interviews and focus groups were conducted in three states in Australia, namely Queensland, the northern region of New South Wales and Western Australia, between December 2011 and March 2012. There were 98 participants consisting of consumers and carers (n = 74), health professionals (n = 13) and representatives from consumer organisations (n = 11). Participants highlighted a need for improved staff awareness. Consumers indicated a desire to receive information in a way that respects their privacy and confidentiality, in an appropriate space. Areas identified that require improved protection of privacy and confidentiality during pharmacy interactions were the number of staff having access to sensitive information, workflow models causing information exposure and pharmacies' layout not facilitating private discussions. Challenges experienced by carers created feelings of isolation which could impact on care. This study explored mental health stakeholders' experiences and expectations regarding privacy and confidentiality in the Australian community pharmacy context. A need for better pharmacy staff training about the importance of privacy and confidentiality and strategies to enhance compliance with national pharmacy practice requirements was identified. Findings provided insight into privacy and confidentiality needs and will assist in the development of pharmacy staff training material to better support consumers with sensitive conditions. © 2014 Royal Pharmaceutical Society.

The erosion of psychiatrist-patient confidentiality by subpoenas.

Science.gov (United States)

Levy, John; Galambos, Gary; Skarbek, Yvonne

2014-08-01

We explore the reasons for the prolific use of subpoenas to gain access to psychiatric records in Australia. We examine the applicable legal principles and practices at the New South Wales (NSW) and Commonwealth levels, aiming to develop recommendations for Australian Governments to curb the inappropriate and harmful use of subpoenas. Unfettered legal access to psychiatric records is inconsistent with professional ethical guidelines and risks undermining the provision of quality psychiatric care to the community. The existing legal provisions are failing to protect psychiatrist-patient confidentiality. In NSW, the onus is placed on the psychiatrist and/or patient to make a complicated application to the court, to direct that a subpoena be set aside on the grounds of "Professional Confidential Relationship Privilege." An absence of Commonwealth legislation to protect psychiatrist-patient confidentiality is used by some litigants in family law proceedings to disadvantage patients by stigmatising them, because they have consulted psychiatrists. We recommend that uniform legislation be implemented, giving effect to a primary rule of privilege with exceptions. © The Royal Australian and New Zealand College of Psychiatrists 2014.

Improved Message Authentication and Confidentiality Checking

International Nuclear Information System (INIS)

Ismail Jabiullah, M.; Abdullah Al-Shamim, M.; Lutfar Rahman, M.

2005-01-01

The most confusing areas of the secured network communications are the message authentication and confidentiality checking. The attacks and the counter measures have become so convoluted that the users in this area begin to account for all contingencies. Two session-key generation techniques are used here to generate two separate session keys K 1 and K 2 ; and both the sender and the reveiver share these keys for higher degree of authentication and confidentiality. For this, the message is first encrypted by the key K 1 , and then the intermediary message authenticatin code (MAC) is generated by encrypting the encrypted message using the key K 2 . Then, the encrypted message and the intermediary MAC is again encrypted by using the K 2 and concatenated with the encrypted message and sent to the destination. At the receiving end, first, the received ciphertext is encrypted by using key K 2 and compared to the received MAC. The received ciphertext again is decrypted by the key K 2 and compared with the first decrypted MAC twice by the key K 2 . The plaintext is obtained by decrypting the received ciphertext first by K 2 and then by K 1 , using the corresponding decryption techniques respectively. The encryption techniques with key K 2 provides the authentication and with key K 1 provides the confidentiality checking of the transmitted message. The developed technique can be applied to both academic and commercial applications in online or offline electronic transactions for security.(authors)

Access control and confidentiality in radiology

Science.gov (United States)

Noumeir, Rita; Chafik, Adil

2005-04-01

A medical record contains a large amount of data about the patient such as height, weight and blood pressure. It also contains sensitive information such as fertility, abortion, psychiatric data, sexually transmitted diseases and diagnostic results. Access to this information must be carefully controlled. Information technology has greatly improved patient care. The recent extensive deployment of digital medical images made diagnostic images promptly available to healthcare decision makers, regardless of their geographic location. Medical images are digitally archived, transferred on telecommunication networks, and visualized on computer screens. However, with the widespread use of computing and communication technologies in healthcare, the issue of data security has become increasingly important. Most of the work until now has focused on the security of data communication to ensure its integrity, authentication, confidentiality and user accountability. The mechanisms that have been proposed to achieve the security of data communication are not specific to healthcare. Data integrity can be achieved with data signature. Data authentication can be achieved with certificate exchange. Data confidentiality can be achieved with encryption. User accountability can be achieved with audits. Although these mechanisms are essential to ensure data security during its transfer on the network, access control is needed in order to ensure data confidentiality and privacy within the information system application. In this paper, we present and discuss an access control mechanism that takes into account the notion of a care process. Radiology information is categorized and a model to enforce data privacy is proposed.

To evaluate the influence of various predictors on the healing outcome 2-6 years after apical microsurgery (AMS) using MTA as the root-end filling material. A total of 90 anterior teeth with asymptomatic persistent periradicular periodontitis of strictly endodontic origin that failed after either nonsurgical or surgical treatment were included. Surgery was completed under local anaesthesia using a standardized clinical protocol. Clinical and radiographic measures as well as the follow-up period were used to determine the healing outcome. For statistical analysis of the predictors, the outcome was dichotomized into healed cases and nonhealed cases. Odds ratios were calculated, and Pearson chi-square or Fisher's exact tests were used to analyse the data. Clinical and radiographic assessment of AMS revealed that 80% were healed, 14.4% were nonhealed, whilst 5.6% were judged to be uncertain. None of the various predictors investigated had a significant influence on the outcome of AMS. The results of this clinical study demonstrated that 80% of cases that received apical microsurgery healed when using MTA as the root-end filling material. © 2015 International Endodontic Journal.

2016-03-01

The confidentiality of family planning services remains a high priority to adolescents, but barriers to implementing confidentiality and privacy practices exist in settings designed for teenagers who are medically underserved, including federally qualified health centers (FQHCs). A sample of 423 FQHCs surveyed in 2011 provided information on their use of five selected privacy and confidentiality practices, which were examined separately and combined into an index. Regression modeling was used to assess whether various state policies and organizational characteristics were associated with FQHCs' scores on the index. In-depth case studies of six FQHCs were conducted to provide additional contextual information. Among FQHCs reporting on confidentiality, most reported providing written or verbal information regarding adolescents' rights to confidential care (81%) and limiting access to family planning and medical records to protect adolescents' confidentiality (84%). Far fewer reported maintaining separate medical records for family planning (10%), using a security block on electronic medical records to prevent disclosures (43%) or using separate contact information for communications regarding family planning services (50%). Index scores were higher among FQHCs that received Title X funding than among those that did not (coefficient, 0.70) and among FQHCs with the largest patient volumes than among those with the smallest caseloads (0.43). Case studies highlighted how a lack of guidelines and providers' confusion over relevant laws present a challenge in offering confidential care to adolescents. The organizational practices used to ensure adolescent family planning confidentiality in FQHCs are varied across organizations. Copyright © 2016 by the Guttmacher Institute.

Studies on indirect pulp treatment (IPT) show varying success rates of 73 to 97 %. The necessity of re-opening the cavity and the question of the optimal capping material is still under debate. The aim of this prospective in vivo study was to compare the clinical and microbiological outcomes of mineral trioxide aggregate (MTA), medical Portland cement, and calcium hydroxide on the dentin-pulp complex of permanent and primary teeth treated with two-step IPT. In 86 regular patients (51 % men; 49 % women; age 17.2 years ±13.8), one deep carious lesion each was treated with incomplete caries removal, randomly selected capping with either calcium hydroxide (n = 31), medical Portland cement (29) or white MTA (26), and re-entry (6.3 months ±1.0). Clinical (color, humidity, and consistency of dentin) and microbiological (Lactobacilli/Mutans Strep. counts) parameters were recorded at the first and second treatment. The IPT had a high success rate of 90.3 % regardless of the material used (p = 0.72). The arrested lesions showed consistently darker, dry, and therefore, sclerotic dentine (p Portland cement. The findings of this study could promote the improvement of the IPT as a one-step treatment of deep carious lesions when the remaining demineralized dentin would be sealed with durable restorations.

2009-09-01

Using the agar diffusion method, we conducted an in vitro study to evaluate the antimicrobial activity of mineral trioxide aggregate (MTA), new endodontic cement (NEC) and Portland cement at different concentrations against five different microorganisms. A base layer was made using Muller-Hinton agar for Escherichia coli (ATCC 10538) and Candida (ATCC 10231). For Actinomyces viscosus (ATCC 15987), Enterococcus faecalis (ATCC 10541) and Streptococcus mutans (ATCC 25175) blood agar medium was used. Wells were formed by removing the agar, and the materials were placed in the well immediately after manipulation. The plates were kept at room temperature for 2 h for prediffusion, and then incubated at 37 degrees C for 72 h. The inhibition zones were then measured. The data were analyzed using ANOVA and the Tukey test to compare the differences among the three cements at different concentrations. The positive controls showed bacterial growth, while the negative controls showed no bacterial growth. All materials showed antimicrobial activity against the tested strains except for Enterococcus faecalis. NEC created larger inhibition zones than MTA and Portland cement. This difference was significant for Portland cement (P 0.05). Among the examined microorganisms, the largest inhibition zone was observed for Actinomyces group (P < 0.05). The antimicrobial activity of the materials increased with time and concentration (P < 0.05). It was concluded that NEC is a potent inhibitor of microorganism growth.

Doctor-patient confidentiality - right and duty of a doctor in law regulations

Directory of Open Access Journals (Sweden)

Janusz Jaroszyński

2018-03-01

Full Text Available Physician’s professional secrecy is one of the most important duties of a doctor and should be provided with confidentiality regarding his or her health. Generally speaking, there is no legal definition of "physician’s professional secrecy" in Poland, although this concept already appears in the oath of Hippocrates: ‘I will keep secret anything I see or hear professionally which ought not to be told’. The issue of medical confidentiality (physician’s professional secrecy has been regulated in several legal acts such as: The Patient Rights and Patients Ombudsman Act, The Constitution of the Republic of Poland, The Medical Profession Act, The Civil Code Act, The Criminal Code Act and Code of Medical Ethics which is not considered as a legal act. The patient has the right to require confidentiality of the information concerning him and the obligation to keep medical confidentiality will apply to every representative of the medical profession, who obtained certain information by various professional activities.

Paternalistic breaches of confidentiality in prison: mental health professionals' attitudes and justifications.

Science.gov (United States)

Elger, Bernice Simone; Handtke, Violet; Wangmo, Tenzin

2015-06-01

This manuscript presents mental health practitioners' (MHPs) practice, attitudes and justifications for breaching confidentiality when imprisoned patients disclose suicidal thoughts or abuse by others. 24 MHPs working in Swiss prisons shared their experiences regarding confidentiality practices. The data were analysed qualitatively and MHPs' attitudes and course of action were identified. Analysis revealed paternalistic breaches of confidentiality. When patients reported suicidal thoughts and abuse, MHPs believed that forgoing confidentiality is necessary to protect patients, providing several justifications for it. Patients were informed that such information will be transmitted without their consent to medical and non-medical prison personnel. With reference to suicidal attempts, MHPs resorted to methods that may reduce suicidal attempts such as transfer to hospital or internal changes in living arrangements, which would require provision of certain information to prison guards. In cases of abuse, some MHPs convinced patients to accept intervention or sometimes overrode competent patients' refusals to report. Also in the case of abuse, provision of limited information to other prison personnel was seen as an acceptable method to protect patients from further harm. Breaches of confidentiality, whether limited or full, remain unethical, when used for competent patients based solely on paternalistic justifications. Institutionalising ethical and legal procedures to address suicidal and abuse situations would be helpful. Education and training to help both medical and prison personnel to respond to such situations in an appropriate manner that ensures confidentiality and protects patients from suicide and abuse are necessary.

Confidential data in a competitive utility environment: A regulatory perspective

Energy Technology Data Exchange (ETDEWEB)

Vine, E.

1996-08-01

Historically, the electric utility industry has been regarded as one of the most open industries in the United States in sharing information but their reputation is being challenged by competitive energy providers, the general public, regulators, and other stakeholders. As the prospect of competition among electricity power providers has increased in recent years, many utilities have been requesting that the data they submit to their utility regulatory commissions remain confidential. Withholding utility information from the public is likely to have serious and significant policy implications with respect to: (1) consumer education, the pursuit of truth, mutual respect among parties, and social cooperation; (2) the creation of a fair market for competitive energy services; (3) the regulatory balance; (4) regional and national assessments of energy-savings opportunities; (5) research and development; and (6) evaluations of utility programs, plans, and policies. In a telephone survey of all public utility commissions (PUCs) that regulate electric and gas utilities in the U.S., we found that almost all PUCs have received requests from utility companies for data to be filed as confidential, and confidential data filings appear to have increased (both in scope and in frequency) in those states where utility restructuring is being actively discussed. The most common types of data submitted as confidential by utilities dealt with specific customer data, market data, avoided costs, and utility costs.

Security without obscurity a guide to confidentiality, authentication, and integrity

2014-01-01

The traditional view of information security includes the three cornerstones: confidentiality, integrity, and availability; however the author asserts authentication is the third keystone. As the field continues to grow in complexity, novices and professionals need a reliable reference that clearly outlines the essentials. Security without Obscurity: A Guide to Confidentiality, Authentication, and Integrity fills this need. Rather than focusing on compliance or policies and procedures, this book takes a top-down approach. It shares the author's knowledge, insights, and observations about infor

Confidentiality, anonymity and amnesty for midwives in distress seeking online support - Ethical?

Science.gov (United States)

Pezaro, Sally; Clyne, Wendy; Gerada, Clare

2018-06-01

Midwife health is intrinsically linked to the quality of safe patient care. To ensure safe patient care, there is a need to deliver emotional support to midwives. One option that midwives may turn to may be a confidential online intervention, instead of localised, face-to-face support. Following the Realist And MEta-narrative Evidence Syntheses: Evolving Standards publication standards, this realist synthesis approach explores the ethical considerations in permitting confidentiality, anonymity and amnesty in online interventions to support midwives in work-related psychological distress. An iterative search methodology was used to select nine papers for review. To assimilate information, papers were examined for ideas relating to ethical dimensions of online interventions to support midwives in work-related psychological distress. This review takes a narrative approach. Online interventions can support the development of insight, help seeking and open discussion. Additionally, Internet support groups can become morally persuasive in nature. Anonymity and confidentiality are both effective and therapeutic features of online interventions when used in collaboration with effective online moderation. Yet, ethical dilemmas remain where users cannot be identified. Confidentiality and anonymity remain key components of successful online interventions. However, sanctioning the corollary component of amnesty may provoke moral discomfort for those seeking immediate accountability. For others, amnesty is seen as essential for open disclosure and help seeking. Ultimately, the needs of midwives must be balanced with the requirement to protect the public and the professional reputation of midwifery. In supporting midwives online, the principles of anonymity, confidentiality and amnesty may evoke some resistance on ethical grounds. However, without offering identity protection, it may not be possible to create effective online support services for midwives. The authors of this

Attitudes toward medical and genetic confidentiality in the Saudi research biobank: An exploratory survey.

2016-03-01

Achieving a balance between giving access to information and respecting donors' confidentiality is a crucial issue for any biobank, with its large number of samples and associated information. Despite the existence of much empirical literature on confidentiality, there are too few surveys in the Middle East about the topic, particularly in the Saudi context. A survey was conducted of 200 respondents at King Abdulaziz Medical City in Riyadh, Saudi Arabia, among 5 groups of equal size, comprised of researchers, physicians, medical students, donors and laypersons, respectively. The majority of participants agreed that confidentiality is an important issue and that it is well protected in the Saudi biobank. All 5 groups showed different attitudes toward disclosing information to various third parties. They were in favor of allowing treating physicians, and to a certain extent family members, to have access to medical and genetic results from research. No significant differences were found between views on medical and genetic confidentiality. The majority of respondents agreed that confidentiality might be breached in cases with specific justified reasons. Even considering differences in religion, culture and other factors, the results of the study were consistent with those reported in the literature and research conducted in other countries. We therefore place emphasis on the importance of protecting and promoting patient/donor confidentiality and privacy. Copyright © 2016. Published by Elsevier Ireland Ltd.

Full Text Available The article discusses the different approaches to assessing the safety of confidential information-term for information and telecommunication systems of various pre-appreciable destination in the presence of internal and external threats to its integrity and availability. The difficulty of ensuring the security of confidential information from exposure to information and telecommunication systems of external and internal threats at the present time, is of particular relevance. This problem is confirmed by the analysis of available statistical information on the impact of threats on the security circulating in the information and telecommunications system. Leak confidential information, intellectual property, information, know-how is the result of significant material and moral damage caused to the owner of the restricted information. The paper presents the structure of the indicators and criteria shows that the most promising are analytical criteria. However, their use to assess the level of security of confidential information is difficult due to the lack of appropriate mathematical models. The complexity of the problem is that existing traditional mathematical models are not always appropriate for the stated objectives. Therefore, it is necessary to develop mathematical models designed to assess the security of confidential information and its impact on information and telecommunication system threats.

Otherwise, the information given by patients to health professionals would not be reliable and a trustable relationship could not be established. The aim of the present study was to assess, by means of questionnaires with open and closed questions, the awareness and attitudes of 100 dentists working in the city of Andradina, São Paulo State, Brazil, with respect to professional confidentiality in dental practice. Most dentists (91.43% reported to have instructed their assistants on professional confidentiality.

Ombuds’ corner: Open door and confidentiality

CERN Multimedia

2013-01-01

For the Open Days, CERN will be transparent for all visitors. It's also the occasion to remember that the Ombuds' door is fully open every day of the year for all persons working for or on behalf of CERN.   The door is open, but as soon as it's closed for a discussion, the office becomes a place where total confidentiality is preserved. This may appear as a contradiction, no? The Ombuds is available to help everyone in all circumstances, but his clause of confidentiality prevents him from acting without the consent of his “visitors”. How can he possibly resolve the in-house conflicts in groups, or units, if all the parties do not voluntarily participate in its resolution? The answer is clear: the job of the Ombuds is to help the parties resolve their conflict by themselves. He will provide a few rules of communication, a process of mutual respect, suggest some possibilities that the parties may want to follow, and mediate the dispute so that people...

Confidentiality, 'no blame culture' and whistleblowing, non-physician practice and accountability.

Science.gov (United States)

White, Stuart M

2006-12-01

Confidentiality is a core tenet of medical professionalism, which enables the maintenance of trust in a doctor-patient relationship. However, both the amount of personal data stored and the number of third parties who might access this data have increased dramatically in the digital age, necessitating the introduction of various national data protection acts. Paradoxically, the Freedom of Information Act 2000 allows United Kingdom citizens to access information held by public bodies, including hospitals. Furthermore, the Public Interest Disclosure Act 1998 actively protects physicians who breach their duty of confidentiality in the name of public interest ('whistleblowing'). This article explores the evolution of the law and ethics in this area, and draws attention to the difficulties in balancing confidentiality against freedom of information. In addition, the role and responsibilities of the non-physician anaesthetist are examined.

[Confidentiality in medical oaths: (When the white crow becomes gray...)].

Science.gov (United States)

Gelpi, R J; Pérez, M L; Rancich, A M; Mainetti, J A

2000-01-01

Confidentiality, together with the ethical principles of beneficence and non-maleficence, is the most important rule in Medical Oaths at the present time. However, the scientific-technical advances in medicine have made this rule one of the most controversial ones because of its exceptions. In consequence, the aim of the present paper is to comparatively analyze the rule of confidentiality in Medical Oaths of different places, times, origins and in different versions of the Hippocratic Oath in order to determine what should be kept a secret and with what degree of commitment (absolute or "prima facie"). Of the thirty six analyzed Oaths, twenty-seven manifest this rule and nine do not. No relation was found between the manifestation of this rule and the place, time, origin and different versions of the Hippocratic Oath. Most pledges suggest not to reveal what has been seen or heard during the medical act, the same as in the Hippocratic Oath. Seven texts point out that confidentiality should be absolute and four give exceptions in connection with beneficence and justice principles and the moral duty of causing no damage to third parties. Two pledges specify protection of privacy. In conclusion, today confidentiality is considered to be a moral duty for the benefit of the patient and out of consideration for his autonomy; however, at the present time in medicine the duty of keeping absolute secrecy is being reconsidered.

2008-12-01

To compare the sealing ability of four hydraulic cements when used as an apical plug in teeth with wide-open apices. A sample of 70 maxillary central incisors were divided into four groups (n = 15) and a further 10 teeth served as controls. An artificial open apex was created in the teeth using Gates Glidden drills numbers 6-1 in a crown-down manner until the size 1 bur passed through the foramen. A divergent open apex was prepared to a size of 1.24 mm at the foramen by retrograde apical transportation using a number 8 (0.60) Profile Series 29 0.4 taper instrument inserted to the length of the cutting blade. In G1, the open apices were repaired with WMTA Angelus whilst in G2, G3 and G4 MTA Bio, Pro-Root MTA and Portland cement was employed respectively. Each root was assembled in a hermetic cell to allow the evaluation of fluid filtration. Leakage was measured by the movement of an air bubble travelling within a pipette connected to the teeth. Measurements of the air bubble movement were made after 10 min at a constant pressure of 50 cm H(2)O. The Kruskal-Wallis H-test was applied to the fluid flow data to detect differences between the experimental groups (P 0.05). Fluid movement through teeth with open apices and filled with four hydraulic cements was similar. All cements allowed fluid movement.

Recent results from the Multimodal Treatment Study of Attention-Deficit/Hyperactivity Disorder (ADHD; MTA) have demonstrated impairments in several functioning domains in adults with childhood ADHD. The childhood predictors of these adult functional outcomes are not adequately understood. The objective of the present study was to determine the effects of childhood demographic, clinical, and family factors on adult functional outcomes in individuals with and without childhood ADHD from the MTA cohort. Regressions were used to determine associations of childhood factors (age range 7-10 years) of family income, IQ, comorbidity (internalizing, externalizing, and total number of non-ADHD diagnoses), parenting styles, parental education, number of household members, parental marital problems, parent-child relationships, and ADHD symptom severity with adult outcomes (mean age 25 years) of occupational functioning, educational attainment, emotional functioning, sexual behavior, and justice involvement in participants with (n = 579) and without (n = 258) ADHD. Predictors of adult functional outcomes in ADHD included clinical factors such as baseline ADHD severity, IQ, and comorbidity; demographic factors such as family income, number of household members and parental education; and family factors such as parental monitoring and parental marital problems. Predictors of adult outcomes were generally comparable for children with and without ADHD. Childhood ADHD symptoms, IQ, and household income levels are important predictors of adult functional outcomes. Management of these areas early on, through timely treatments for ADHD symptoms, and providing additional support to children with lower IQ and from households with low incomes, could assist in improving adult functioning.

Rekonstruksi Pengaturan Confidential Principle bagi Komunikasi pada Mediasi Sengketa Perdata di Indonesia: Studi Perbandingan dengan Praktik di Amerika Serikat

Directory of Open Access Journals (Sweden)

I Gusti Ngurah Parikesit

2016-04-01

Full Text Available Peran mediasi sebagai penyelesaian sengketa alternatif untuk sengketa perdata yang semakin populer digunakan pada praktiknya belum berjalan maksimal. Salah satu penyebabnya adalah kekaburan pengaturan prinsip kerahasiaan confidential principle bagi komunikasi yang terjadi pada proses mediasi. Aturan hukum di Indonesia hanya menjelaskan bahwa mediasi dilangsungkan berdasarkan pada asas tertutup dan mediator berkewajiban menjaga kerahasiaan, baik dalam bentuk perkataan maupun catatan, yang terungkap pada mediasi. Sebagai perbandingan, aturan hukum di Amerika Serikat sudah diatur bahwa segala bentuk komunikasi yang terjadi dan berhubungan dengan pelaksanaan mediasi tunduk pada confidential principle, sehingga proses komunikasi mendapatkan hak istimewa (privilege dengan tidak dapat dijadikan barang bukti dan seluruh pihak yang terlibat dalam mediasi tidak dapat dijadikan saksi pada persidangan berikutnya. Dengan demikian, dibutuhkan rekonstruksi pengaturan terkait ruang lingkup komunikasi pada proses mediasi yang terkualifikasi sebagai confidential principle pengaturan terkait pelepasan hak istimewa komunikasi dari confidential principle; dan pengaturan terkait pengecualian terhadap komunikasi yang terkualifikasi sebagai confidential principle Abstract Although being popular, the role of mediation in resolving civil disputes is yet to be maximalized. One of the reasons is the the vague regulation concerning the confidential principle for communication in mediation. The existing regulation in Indonesia only explains that mediation is undertaken based on closed principle and the mediator is obliged to maintain confidentiality the confidentiality of any communication, either in oral or written forms, revealed during mediation. Whereas in comparison, the regulation in the United States of America stipulates that all forms of communications occured during mediation or is made for purposes of conducting or participating in mediation are subjects to the

To develop a visual rating scale for posterior atrophy (PA) assessment and to analyse whether this scale aids in the discrimination between Alzheimer's disease (AD) and other dementias. Magnetic resonance imaging of 118 memory clinic patients were analysed for PA (range 0-3), medial temporal lobe atrophy (MTA) (range 0-4) and global cortical atrophy (range 0-3) by different raters. Weighted-kappas were calculated for inter- and intra-rater agreement. Relationships between PA and MTA with the MMSE and age were estimated with linear-regression analysis. Intra-rater agreement ranged between 0.93 and 0.95 and inter-rater agreement between 0.65 and 0.84. Mean PA scores were higher in AD compared to controls (1.6 ± 0.9 and 0.6 ± 0.7, p < 0.01), and other dementias (0.8 ± 0.8, p < 0.01). PA was not associated with age compared to MTA (B = 1.1 (0.8) versus B = 3.1 (0.7), p < 0.01). PA and MTA were independently negatively associated with the MMSE (B = -1.6 (0.5), p < 0.01 versus B = -1.4 (0.5), p < 0.01). This robust and reproducible scale for PA assessment conveys independent information in a clinical setting and may be useful in the discrimination of AD from other dementias. (orig.)

Chalee Vorakulpipat

2017-01-01

Full Text Available Today, many organizations allow their employees to bring their own smartphones or tablets to work and to access the corporate network, which is known as a bring your own device (BYOD. However, many such companies overlook potential security risks concerning privacy and confidentiality. This paper provides a review of existing literature concerning the preservation of privacy and confidentiality, with a focus on recent trends in the use of BYOD. This review spans a large spectrum of information security research, ranging from management (risk and policy to technical aspects of privacy and confidentiality in BYOD. Furthermore, this study proposes a policy-based framework for preserving data confidentiality in BYOD. This framework considers a number of aspects of information security and corresponding techniques, such as policy, location privacy, centralized control, cryptography, and operating system level security, which have been omitted in previous studies. The main contribution is to investigate recent trends concerning the preservation of confidentiality in BYOD from the perspective of information security and to analyze the critical and comprehensive factors needed to strengthen data privacy in BYOD. Finally, this paper provides a foundation for developing the concept of preserving confidentiality in BYOD and describes the key technical and organizational challenges faced by BYOD-friendly organizations.

[Confidentiality in HIV-infection/AIDS--a comment on the Communicable Disease Control Act].

Science.gov (United States)

Frich, J C

1995-05-10

The new Communicable Diseases Control Act has come into force in Norway. It makes it compulsory for a physician to warn a third party if it is obvious that a HIV-positive patient, with a high degree of certainty, puts the third party at risk of being infected with HIV. Some philosophers characterize medical confidentiality as an intransigent and absolute obligation, others as a prima facie duty. This article supports the latter view, but the author still argues that strict conditions have to be fulfilled before a physician should consider breaking medical confidentiality: The doctor must try repeatedly to gain the consent or co-operation of the patient involved. Possible negative long-term consequences for the preventive HIV-work support strict medical confidentiality.

International Nuclear Information System (INIS)

Juppe, Alain; Fillon, Francois

2011-01-01

This document is related to the nuclear cooperation agreement signed in September 2008 between France and India. As this cooperation may have different aspects and lead to different kinds of exchanges between both countries, the allocation of intellectual property rights is an important issue, and has also to deal with the Indian legal context. Thus, this agreement defines the main notions (intellectual property, application agreement, common results, own knowledge), outlines the importance of intellectual property protection, defines the modalities of use of information, outlines the need to foresee a protection for confidential information, addresses the use of information which is already existing or which is produced within the cooperation, and defines the main guidelines for the protection, the allocation and the use of common results obtained within the cooperation

Enhanced Obfuscation Technique for Data Confidentiality in Public Cloud Storage

Directory of Open Access Journals (Sweden)

Oli S. Arul

2016-01-01

Full Text Available With an advent of cloud computing, data storage has become a boon in information technology. At the same time, data storage in remote places have become important issues. Lot of techniques are available to ensure protection of data confidentiality. These techniques do not completely serve the purpose in protecting data. The Obfuscation techniques come to rescue for protecting data from malicious attacks. This paper proposes an obfuscation technique to encrypt the desired data type on the cloud providing more protection from unknown hackers. The experimental results show that the time taken for obfuscation is low and the confidentiality percentage is high when compared with existing techniques.

Medical confidentiality versus disclosure: Ethical and legal dilemmas.

LENUS (Irish Health Repository)

Agyapong, V I O

2009-02-01

A case is described of a fifty year old single man who made disclosures about criminal sexual practices during a psychiatric assessment. In common practice with other professional men, a doctor is under a duty not to disclose, without the consent of his patient, information which he has gained in his professional capacity other than in exceptional circumstances. We discuss the ethical and legal considerations surrounding issues of medical confidentiality and the dilemma that sometimes face clinicians, when they feel obliged, in the public interest, to disclose information they have gained in confidence. Breach of confidences can have deleterious consequences; particularly for the doctor-patient relationship, but failure to disclose in some situations could have serious implications for the well-being of the wider society. Doctors should be aware of the basic principles of confidentiality and the ethical and legal framework around which they are built.

Privacy, confidentiality and automated health information systems.

Science.gov (United States)

Vuori, H

1977-12-01

Professor Vuori's paper, first presented at the fourth Medico-legal Conference in Prague in the spring of this year, deals with the problem of the maintenance of confidentiality in computerized health records. Although more and more information is required, the hardware of the computer systems is so sophisticated that it would be very expensive indeed to 'break in' and steal from a modern data bank. Those concerned with programming computers are becoming more aware of their responsibilities concerning confidentiality and privacy, to the extent that a legal code of ethics for programmers is being formulated. They are also aware that the most sensitive of all relationships--the doctor-patient relationship--could be in danger if they failed to maintain high standards of integrity. An area of danger is where administrative boundaries between systems must be crossed--say between those of health and employment. Protection of privacy must be ensured by releasing full information about the type of data being stored, and by maintaining democratic control over the establishment of information systems.

Confidentiality Enhancement of Highly Sensitive Nuclear Data Using Steganography with Chaotic Encryption over OFDM Channel

International Nuclear Information System (INIS)

Mahmoud, S.; Ayad, N.; Elsayed, F.; Elbendary, M.

2016-01-01

Full text: Due to the widespread usage of the internet and other wired and wireless communication methods, the security of the transmitted data has become a major requirement. Nuclear knowledge is mainly built upon the exchange of nuclear information which is considered highly sensitive information, so its security has to be enhanced by using high level security mechanisms. Data confidentiality is concerned with the achievement of higher protection for confidential information from unauthorized disclosure or access. Cryptography and steganography are famous and widely used techniques that process information in order to achieve its confidentiality, but sometimes, when used individually, they don’t satisfy a required level of security for highly sensitive data. In this paper, cryptography is accompanied with steganography for constituting a multilayer security techniques that can strengthen the level of security of highly confidential nuclear data that are archived or transmitted through different channel types and noise conditions.

The end of medical confidentiality? Patients, physicians and the state in history.

Science.gov (United States)

Rieder, Philip; Louis-Courvoisier, Micheline; Huber, Philippe

2016-09-01

Medical confidentiality has come under attack in the public sphere. In recent disasters both journalists and politicians have questioned medical confidentiality and claimed that in specific contexts physicians should be compelled to communicate data on their patients' health. The murders of innocent individuals by a suicidal pilot and a Swiss convicted criminal have generated polemical debates on the topic. In this article, historical data on medical confidentiality is used to show that medical practices of secrecy were regularly attacked in the past, and that the nature of medical confidentiality evolved through time depending on physicians' values and judgements. Our demonstration is based on three moments in history. First, at the end of the 16th century, lay authorities put pressure on physicians to disclose the names of patients suffering from syphilis. Second, in the 18th century, physicians faced constant demands for information about patients' health from relatives and friends. Third, employers and insurance companies in the 20th century requested medical data on sick employees. In these three different situations, history reveals that the concept of medical confidentiality was plastic, modelled in the first instance to defend well-to-do patients, in the second instance it was adapted to accommodate the physician's social role and, finally, to defend universal values and public health. Medical secrecy was, and is today, a medical and societal norm that is shaped collectively. Any change in its definition and enforcement was and should be the result of negotiations with all social actors concerned. Published by the BMJ Publishing Group Limited.

Boundaries of confidentiality in nursing care for mother and child in HIV programmes.

Science.gov (United States)

Våga, Bodil Bø; Moland, Karen Marie; Blystad, Astrid

2016-08-01

Confidentiality lies at the core of medical ethics and is the cornerstone for developing and keeping a trusting relationship between nurses and patients. In the wake of the HIV epidemic, there has been a heightened focus on confidentiality in healthcare contexts. Nurses' follow-up of HIV-positive women and their susceptible HIV-exposed children has proved to be challenging in this regard, but the ethical dilemmas concerning confidentiality that emerge in the process of ensuring HIV-free survival of the third party - the child - have attracted limited attention. The study explores challenges of confidentiality linked to a third party in nurse-patient relationships in a rural Tanzanian HIV/AIDS context. The study was carried out in rural and semi-urban settings of Tanzania where the population is largely agro-pastoral, the formal educational level is low and poverty is rife. The HIV prevalence of 1.5% is low compared to the national prevalence of 5.1%. Data were collected during 9 months of ethnographic fieldwork and consisted of participant observation in clinical settings and during home visits combined with in-depth interviews. The main categories of informants were nurses employed in prevention of mother-to-child transmission of HIV programmes and HIV-positive women enrolled in these programmes. Based on information about the study aims, all informants consented to participate. Ethical approval was granted by ethics review boards in Tanzania and Norway. The material indicates a delicate balance between the nurses' attempt to secure the HIV-free survival of the babies and the mothers' desire to preserve confidentiality. Profound confidentiality-related dilemmas emerged in actual practice, and indications of a lack of thorough consideration of the implication of a patient's restricted disclosure came to light during follow-up of the HIV-positive women and the third party - the child who is at risk of HIV infection through mother's milk.

HIV testing sites' communication about adolescent confidentiality: potential barriers and facilitators to testing.

Science.gov (United States)

Hyden, Christel; Allegrante, John P; Cohall, Alwyn T

2014-03-01

This study sought to evaluate HIV testing locations in New York City in terms of staff communication of confidentiality policies for adolescent clients. Using the New York State Directory of HIV Counseling and Testing Resources as a sampling frame, this study made telephone contact with 164 public HIV testing locations in New York City and used a semistructured interview to ask questions about confidentiality, parental permission, and parent access to test results. At 48% of locations, either HIV testing was not offered or we were unable to reach a staff member to ask questions about testing options and confidentiality. At the remaining sites, information provided regarding confidentiality, parental consent, and privacy of test results was correct only 69% to 85% of the time. Additionally, 23% of sites successfully contacted offered testing exclusively between 9:00 a.m. and 3:00 p.m. weekdays, when most adolescents are in school. Our findings point to a need for increased training and quality control at the clinical level to ensure that consumers in need of HIV testing are provided with accurate information and accessible services. Furthermore, these results highlight the need for more "patient-centric" sites with enhanced accessibility for potential clients, particularly youth.

This study examined nursing students' perceptions of confidentiality, accountability, and e-professionalism in relation to Facebook. All of the students were aware that posting patients' names and pictures of patients constituted a confidentiality breach. When comparing students based on educational status, there were differing opinions on whether employers should use Facebook profile information for hiring decisions. Nursing programs should provide current education, including clear and up-to-date policies, about social media use.

To determine childhood factors that predict attention-deficit/hyperactivity disorder (ADHD) persistence and desistence in adulthood. Regression analyses were used to determine associations between childhood factors and adult ADHD symptom persistence in 453 participants (mean age, 25 years) from the Multimodal Treatment Study of Children with ADHD (MTA). Childhood IQ, total number of comorbidities, child-perceived parenting practices, child-perceived parent-child relationships, parental mental health problems, marital problems of parents, household income levels, and parental education were assessed at a mean age of 8 years in all participants. Adult ADHD persistence was defined using DSM-5 symptom counts either with or without impairment, as well as mean ADHD symptom scores on the Conners' Adult ADHD Rating Scale (CAARS). Age, sex, MTA site, and childhood ADHD symptoms were covaried. The most important childhood predictors of adult ADHD symptom persistence were initial ADHD symptom severity (odds ratio [OR] = 1.89, standard error [SE] = 0.28, p = .025), comorbidities (OR = 1.19, SE = 0.07, p = .018), and parental mental health problems (OR = 1.30, SE = 0.09, p = .003). Childhood IQ, socioeconomic status, parental education, and parent-child relationships showed no associations with adult ADHD symptom persistence. Initial ADHD symptom severity, parental mental health, and childhood comorbidity affect persistence of ADHD symptoms into adulthood. Addressing these areas early may assist in reducing adult ADHD persistence and functioning problems. Copyright © 2016 American Academy of Child and Adolescent Psychiatry. Published by Elsevier Inc.

Public expectations concerning confidentiality protection of adolescents' sexual and reproductive health care in Lithuania: findings of the surveys conducted in 2005 and 2012.

Science.gov (United States)

Jaruseviciene, Lina; Zaborskis, Apolinaras; Lazarus, Jeffrey Victor

2014-04-01

An adolescent's right to confidential healthcare is protected by international law and professional consensus. However, parental and social support for confidential sexual and reproductive health (SRH) services, in particular, varies greatly. This study documents Lithuanian residents' expectations with regard to confidentiality protection for adolescents in this domain, and explores the factors related to the diversity of these expectations. Two national surveys of Lithuanian residents completed in 2005 and 2012 using anonymous questionnaires. Participants rated their expectations for confidentiality using a five-point Likert scale for eight types of SRH consultations. Public anticipation for confidentiality depended on whether issues related to sexual behaviour or to its consequences were addressed during adolescent consultation. Only younger respondents had higher expectations for confidentiality in both contexts. Public expectations regarding confidentiality were less demanding in 2012 than in 2005. The expectation of confidentiality protection was greater for topics related to sexual behaviour than for the consequences of sexual behaviour, such as pregnancy, abortion or a sexually transmitted infection. This implies a need for targeted information strategies for the general population and explicit guidance for physicians on when and for whom care should remain confidential.

Privacy, confidentiality and abortion statistics: a question of public interest?

Science.gov (United States)

McHale, Jean V; Jones, June

2012-01-01

The precise nature and scope of healthcare confidentiality has long been the subject of debate. While the obligation of confidentiality is integral to professional ethical codes and is also safeguarded under English law through the equitable remedy of breach of confidence, underpinned by the right to privacy enshrined in Article 8 of the Human Rights Act 1998, it has never been regarded as absolute. But when can and should personal information be made available for statistical and research purposes and what if the information in question is highly sensitive information, such as that relating to the termination of pregnancy after 24 weeks? This article explores the case of In the Matter of an Appeal to the Information Tribunal under section 57 of the Freedom of Information Act 2000, concerning the decision of the Department of Health to withhold some statistical data from the publication of its annual abortion statistics. The specific data being withheld concerned the termination for serious fetal handicap under section 1(1)d of the Abortion Act 1967. The paper explores the implications of this case, which relate both to the nature and scope of personal privacy. It suggests that lessons can be drawn from this case about public interest and use of statistical information and also about general policy issues concerning the legal regulation of confidentiality and privacy in the future.

Denying a patient's final will: public safety vs. medical confidentiality and patient autonomy.

Science.gov (United States)

Gaertner, Jan; Vent, Julia; Greinwald, Ralf; Rothschild, Markus A; Ostgathe, Christoph; Kessel, Rene; Voltz, Raymond

2011-12-01

Especially when caring for patients approaching the end of life, physicians and nursing staff feel committed to fulfilling as many patient desires as possible. However, sometimes a patient's "final will" may threaten public safety. This can lead to severe conflicts, outweighing the physician's obligation and dedication to care for the patient and to respect his autonomy. Yet, public safety can be threatened if confidentiality is not broken. This article provides a concise summary of the medicolegal and ethical fundamentals concerning this difficult situation. If the patient's and others' health and safety are at risk, physicians may (and in some countries must) break medical confidentiality and disclose confidential patient information to the police and other authorities. Physicians should be able to professionally deal with such a conflict in all patients, not only in patients with advanced illness. Copyright © 2011 U.S. Cancer Pain Relief Committee.

Ensuring Confidentiality of Geocoded Health Data: Assessing Geographic Masking Strategies for Individual-Level Data.

Science.gov (United States)

Zandbergen, Paul A

2014-01-01

Public health datasets increasingly use geographic identifiers such as an individual's address. Geocoding these addresses often provides new insights since it becomes possible to examine spatial patterns and associations. Address information is typically considered confidential and is therefore not released or shared with others. Publishing maps with the locations of individuals, however, may also breach confidentiality since addresses and associated identities can be discovered through reverse geocoding. One commonly used technique to protect confidentiality when releasing individual-level geocoded data is geographic masking. This typically consists of applying a certain amount of random perturbation in a systematic manner to reduce the risk of reidentification. A number of geographic masking techniques have been developed as well as methods to quantity the risk of reidentification associated with a particular masking method. This paper presents a review of the current state-of-the-art in geographic masking, summarizing the various methods and their strengths and weaknesses. Despite recent progress, no universally accepted or endorsed geographic masking technique has emerged. Researchers on the other hand are publishing maps using geographic masking of confidential locations. Any researcher publishing such maps is advised to become familiar with the different masking techniques available and their associated reidentification risks.

Evaluation of the reinforcement effect on teeth with different apical foramen diameters of retrograde or orthograde MTA application with internal matrix

Directory of Open Access Journals (Sweden)

Emre Bayram

2016-01-01

Full Text Available OBJECTIVE: The aim of this study was to determine the effect of the apical foramen diameter and different application methods of Mineral Trioxide Aggregate (MTA on the fracture resistance of simulated immature teeth using a Universal Testing Machine. MATERIALS AND METHOD: Ninety extracted human teeth were used for the fracture resistance test. The apical foramen was prepared to a diameter of 1.0 mm or 1.4 mm to simulate the open apex of immature teeth. MTA was mixed according to manufacturer's recommendations and placed into the root canals with different apical foramen diameter by four different root filling techniques: retrograde, two-phased orthograde, and ortograde with or without internal matrix. Prepared roots were marked 2 mm below the cemento-enamel junction and embedded in transparent acrylic resin in cylinder moulds. Vertical force was applied along the long axis of the tooth at a speed of 5 mm/min, and the maximum resistance to fracture for each tooth was determined in Newton. A software package was used for the statistical analysis. The data were analyzed by using one-way ANOVA and post-hoc Tukey tests. RESULTS: A statistically significant difference could not be observed between the groups (p>0.05 whereas statistically significant differences were found between the test groups and the control groups (p<0.05. CONCLUSION: There was no significant difference between different vertical root filling techniques in increasing the fracture strength of the teeth. The diameter of the apical foramen did not have a significant effect on the fracture resistance.

Martindale, S J; Chambers, E; Thompson, A R

2009-12-01

To explore and describe the experience of clinical psychology service users in relation to the processes associated with confidentiality and the generation of informed consent in individual therapy. A qualitative interview-based study employing interpretative phenomenological analysis was conducted with service users. User researchers were active collaborators in the study. A focus group of four users was convened to explore issues related to confidentiality and consent, which then informed the development of the semi-structured interview schedule. Twelve users of community mental health clinical psychology services were interviewed by user researchers. A user researcher and a clinical psychologist undertook joint analysis of the data. A second clinical psychologist facilitated reflexivity and wider consideration of validity issues. Four main themes were identified from the data: being referred; the participant's feelings, mental health difficulties, and their impact; relationships with workers and carers; and autonomy. The meaningfulness of processes of discussing confidentiality, and generating informed consent, can be improved by psychologists placing a greater emphasis on choice, control, autonomy, individual preferences, and actively involving the user in dialogue on repeated occasions.

2018-03-23

To explore parental and adolescent views on the confidential interview in the gynecologic setting and compare adolescent reported risk-taking behaviors with parental perception. Anonymous surveys were administered separately to parents/guardians and adolescents between the ages of 11-17. Information pertaining to the patient's Tanner stage and reason for visit was obtained from the provider. This first phase served as the usual care group. In the second phase of the study, surveys were once again distributed after a brief educational intervention. Linear regression analysis, Wilcoxon rank sum test, and Fisher exact test were used where appropriate. Pediatric and Adolescent Gynecology clinics in two tertiary hospitals INTERVENTION: Brief educational handout on key concepts of the confidential interview MAIN OUTCOME MEASURES: Parental perception of the confidential interview and adolescent risk- taking behaviors RESULTS: A total of 248 surveys were included in the final analysis, which accounts for 62 adolescent and parent/guardian pairs in each group. The majority of parents and adolescents reported perceived benefit to the confidential interview. However, parents were less likely to rate benefits of private time specifically for their own adolescent and less than half of parents believed that adolescents should have access to private time in the gynecologic setting. Both parents/guardians and adolescents feared that the confidential interview would limit the parent's ability to take part in decision-making. The low support for confidential time for their adolescent was not different in the usual care group as compared to the intervention group, although there was a trend toward parental acceptance with increased adolescent age. Adolescents were consistently more likely to report more risk-taking behaviors than their parents perceived. There is a discord between parental perception and adolescent reports of risk taking behaviors. This is coupled with a lack of

[Consent and confidentiality in occupational health practice: balance between legal requirements and ethical values].

Science.gov (United States)

Mora, Erika; Franco, G

2010-01-01

The recently introduced Italian law on the protection of workers' health states that the occupational health physician (competent physician) is required to act according to the Code of Ethics of the International Commission on Occupational Health (ICOH). This paper aims at examining the articles of legislative decree 81/2008 dealing with informed consent and confidentiality compared with the corresponding points of the ICOH Ethics Code. Analysis of the relationship between articles 25 and 39 (informed consent) and 18, 20 and 39 (confidentiality) of the decree shows that there are some points of disagreement between the legal requirements and the Code of Ethics, in particular concerning prescribed health surveillance, consent based on appropriate information (points 8, 10 and 12 of the Code) and some aspects of confidentiality (points 10, 20, 21, 22 and 23 of the Code). Although the competent physician is required to act according to the law, the decisional process could lead to a violation of workers' autonomy.

THE INFORMATION CONFIDENTIALITY AND CYBER SECURITY IN MEDICAL INSTITUTIONS

SABAU-POPA CLAUDIA DIANA

2015-07-01

Full Text Available The information confidentiality and cyber security risk affects the right to confidentiality and privacy of the patient, as regulated in Romania by the Law 46/2002. The manifestation of the cyber security risk event affects the reputation of the healthcare institution and is becoming more and more complex and often due to the: development of network technology, the medical equipment connected to wifi and the electronic databases. The databases containing medical records were implemented due to automation. Thus, transforming data into medical knowledge contribute to a better understanding of the disease. Due to these factors, the measures taken by the hospital management for this type of risk are adapted to the cyber changes. The hospital objectives aim: the implementation of a robust information system, the early threats identifications and the incident reporting. Neglecting this type of risk can generate financial loss, inability to continue providing health care services for a certain period of time, providing an erroneous diagnosis, medical equipment errors etc. Thus, in a digital age the appropriate risk management for the information security and cyber risk represent a necessity. The main concern of hospitals worldwide is to align with international requirements and obtain credentials in terms of data security from the International Organisation for Standardization, which regulates the management of this type of risk. Romania is at the beginning in terms of concerns regarding the management, avoidance and mitigation of information security, the health system being most highly exposed to its manifestation. The present paper examines the concerns of the health system to the confidentiality of information and cyber security risk and its management arrangements. Thus, a set of key risk indicators is implemented and monitored for 2011-2013, using a user interface, a Dashboard, which acts as an early warning system of the manifestation of the

The issue is whether Christianity, of its nature, would seek to prevent a justifiable breach of confidentiality or could endorse it, under certain circumstances, as the act which is fundamentally more loving or more truthful. The individualistic nature of Western Christianity is noted. The Lutheran theologian Dietrich Bonhoeffer is used to show Christian support for dynamic rather than literal truth telling, and for awareness of the contexts and power relations within which persons stand.

Confidential conversations between supervisor and employee as a means for improving leadership: a quasi-experimental study in hospital wards.

Science.gov (United States)

Kivimäki, M

1996-11-01

Although yearly confidential conversations between a supervisor and an employee have been recommended as a means for improving leadership, evidence on the actual effects of these conversations has been lacking. The present study therefore investigated whether confidential conversations improve perceptions of goal clarity, sufficiency of feedback and innovativeness, and elicit satisfaction with the supervisor's leadership style within the hospital setting. Nine wards were divided into one experimental group (3 wards) and two control groups (3 + 3 wards). A questionnaire on goal clarity, feedback, innovativeness and satisfaction was administered twice to every group (1st measurement: r = 186, 2nd measurement: n = 163). The experimental group began confidential conversations after the first measurement, control group 1 entered into conversations during both measurements, and control group 2 did not enter into conversations at the time of either measurement. Confidential conversations improved perceived feedback. In both measurements, the sufficiency of feedback was reported to be significantly better in the groups having conversations than in the other groups. In addition, there was a significant positive change in the perceived sufficiency of feedback in the experimental group but not in the other groups. Confidential conversations did not affect the perceptions of goal clarity and innovativeness or elicit satisfaction with the supervisor's management style.

Taxpayers' confidentiality and privacy rights in the international exchange of tax information

Directory of Open Access Journals (Sweden)

Anđelković Mileva

2014-01-01

Full Text Available The exchange of tax information is a distinctive feature of international tax cooperation processes. The trend of intensive communication between the national tax administrations has been a political priority in economically developed countries. This area of international tax law has been subject to significant changes in the past few years. Countries are prompted to pursue the automatic exchange of tax information by entering into multilateral treaties on the exchange of tax information rather than engage in international exchange of tax information upon request by entering into bilateral agreements. These processes are promptly expedited owing to the incredible development of information and communication technologies. These developments are basically aimed at preventing different forms of international tax fraud which generate significant financial losses in the circumstances of current economic crisis. Such efforts may be justifiable regarding the interests of the countries of residence; but, what about the legal status of ordinary taxpayers who are now subject to a comprehensive and far-reaching control? The new concept may be appropriate for tracking tax fraud or embezzlement but what are its implications for law-abiding taxpayers? The national legislatures are obliged to provide for the protection of confidentiality of exchanged tax information but many states have not fully recognized the importance of providing adequate legal protection of sensitive personal and financial data. There are only a few countries whose legislations explicitly prescribe the taxpayers' right to be informed, the right to consult tax administration and the right to seek tax administration intervention as a form of legal protection in international exchange of tax information. The Serbian tax legislation does not envisage the obligation of tax authorities to notify the taxpayers about the request submitted by foreign tax authorities to provide some tax

Standards of care are established based on a myriad of factors, including professional codes of ethics, case law, state and federal laws, professional standards, existing best practices, current professional guidelines, administrative rules and regulations, and licensing board regulations. Regulations may differ for behavioral health and medical providers, posing challenges in IPC settings. This article provides a review of these regulations, particularly 42CFR Part 2, a federal law governing confidentiality for substance abuse programs, Health Insurance Portability and Accountability Act (HIPAA), and state laws relevant to patient care in IPC settings. On the basis of findings from the study, the authors make recommendations related to patient care practices concerning informed consent and release of information procedures, treatment and warm hand-off protocols, documentation and electronic record keeping, agreements with other providers, and billing.

Payers' experiences with confidential pharmaceutical price discounts: A survey of public and statutory health systems in North America, Europe, and Australasia.

Science.gov (United States)

Morgan, Steven G; Vogler, Sabine; Wagner, Anita K

2017-04-01

Institutional payers for pharmaceuticals worldwide appear to be increasingly negotiating confidential discounts off of the official list price of pharmaceuticals purchased in the community setting. We conducted an anonymous survey about experiences with and attitudes toward confidential discounts on patented pharmaceuticals in a sample of high-income countries. Confidential price discounts are now common among the ten health systems that participated in our study, though some had only recently begun to use these pricing arrangements on a routine basis. Several health systems had used a wide variety of discounting schemes in the past two years. The most frequent discount received by participating health systems was between 20% and 29% of official list prices; however, six participants reported their health system received one or more discount over the past two years that was valued at 60% or more of the list prices. On average, participants reported that confidential discounts were more common, complex, and significant for specialty pharmaceuticals than for primary care pharmaceuticals. Participants had a more favorable view of the impact of confidential discount schemes on their health systems than on the global marketplace. Overall, the frequency, complexity, and scale of confidential discounts being routinely negotiated suggest that the list prices for medicines bear limited resemblance to what many institutional payers actually pay.

FORENSIC DNA BANKING LEGISLATION IN DEVELOPING COUNTRIES: PRIVACY AND CONFIDENTIALITY CONCERNS REGARDING A DRAFT FROM TURKISH LEGISLATION.

Science.gov (United States)

Ilgili, Önder; Arda, Berna

This paper presents and analyses, in terms of privacy and confidentiality, the Turkish Draft Law on National DNA Database prepared in 2004, and concerning the use of DNA analysis for forensic objectives and identity verification in Turkey. After a short introduction including related concepts, we evaluate the draft law and provide articles about confidentiality. The evaluation reminded us of some important topics at international level for the developing countries. As a result, the need for sophisticated legislations about DNA databases, for solutions to issues related to the education of employees, and the technological dependency to other countries emerged as main challenges in terms of confidentiality for the developing countries. As seen in the Turkish Draft Law on National DNA Database, the protection of the fundamental rights and freedoms requires more care during the legislative efforts.

Conversion of invisible metal-organic frameworks to luminescent perovskite nanocrystals for confidential information encryption and decryption.

Science.gov (United States)

Zhang, Congyang; Wang, Bo; Li, Wanbin; Huang, Shouqiang; Kong, Long; Li, Zhichun; Li, Liang

2017-10-31

Traditional smart fluorescent materials, which have been attracting increasing interest for security protection, are usually visible under either ambient or UV light, making them adverse to the potential application of confidential information protection. Herein, we report an approach to realize confidential information protection and storage based on the conversion of lead-based metal-organic frameworks (MOFs) to luminescent perovskite nanocrystals (NCs). Owing to the invisible and controlled printable characteristics of lead-based MOFs, confidential information can be recorded and encrypted by MOF patterns, which cannot be read through common decryption methods. Through our conversion strategy, highly luminescent perovskite NCs can be formed quickly and simply by using a halide salt trigger that reacts with the MOF, thus promoting effective information decryption. Finally, through polar solvents impregnation and halide salt conversion, the luminescence of the perovskite NCs can be quenched and recovered, leading to reversible on/off switching of the luminescence signal for multiple information encryption and decryption processes.

Anonymous or confidential HIV counseling and voluntary testing in federally funded testing sites--United States, 1995-1997.

Science.gov (United States)

1999-06-25

Human immunodeficiency virus (HIV) counseling and voluntary testing (CT) programs have been an important part of national HIV prevention efforts since the first HIV antibody tests became available in 1985. In 1995, these programs accounted for approximately 15% of annual HIV antibody testing in the United States, excluding testing for blood donation. CT opportunities are offered to persons at risk for HIV infection at approximately 11,000 sites, including dedicated HIV CT sites, sexually transmitted disease (STD) clinics, drug-treatment centers, hospitals, and prisons. In 39 states, testing can be obtained anonymously, where persons do not have to give their name to get tested. All states provide confidential testing (by name) and have confidentiality laws and regulations to protect this information. This report compares patterns of anonymous and confidential testing in all federally funded CT programs from 1995 through 1997 and documents the importance of both types of testing opportunities.

Contributory factors in surgical incidents as delineated by a confidential reporting system.

Science.gov (United States)

Mushtaq, F; O'Driscoll, C; Smith, Fct; Wilkins, D; Kapur, N; Lawton, R

2018-05-01

Background Confidential reporting systems play a key role in capturing information about adverse surgical events. However, the value of these systems is limited if the reports that are generated are not subjected to systematic analysis. The aim of this study was to provide the first systematic analysis of data from a novel surgical confidential reporting system to delineate contributory factors in surgical incidents and document lessons that can be learned. Methods One-hundred and forty-five patient safety incidents submitted to the UK Confidential Reporting System for Surgery over a 10-year period were analysed using an adapted version of the empirically-grounded Yorkshire Contributory Factors Framework. Results The most common factors identified as contributing to reported surgical incidents were cognitive limitations (30.09%), communication failures (16.11%) and a lack of adherence to established policies and procedures (8.81%). The analysis also revealed that adverse events were only rarely related to an isolated, single factor (20.71%) - with the majority of cases involving multiple contributory factors (79.29% of all cases had more than one contributory factor). Examination of active failures - those closest in time and space to the adverse event - pointed to frequent coupling with latent, systems-related contributory factors. Conclusions Specific patterns of errors often underlie surgical adverse events and may therefore be amenable to targeted intervention, including particular forms of training. The findings in this paper confirm the view that surgical errors tend to be multi-factorial in nature, which also necessitates a multi-disciplinary and system-wide approach to bringing about improvements.

Quantum key based burst confidentiality in optical burst switched networks.

Balamurugan, A M; Sivasubramanian, A

2014-01-01

The optical burst switching (OBS) is an emergent result to the technology concern that could achieve a feasible network in future. They are endowed with the ability to meet the bandwidth requirement of those applications that require intensive bandwidth. There are more domains opening up in the OBS that evidently shows their advantages and their capability to face the future network traffic. However, the concept of OBS is still far from perfection facing issues in case of security threat. The transfer of optical switching paradigm to optical burst switching faces serious downfall in the fields of burst aggregation, routing, authentication, dispute resolution, and quality of service (QoS). This paper deals with employing RC4 (stream cipher) to encrypt and decrypt bursts thereby ensuring the confidentiality of the burst. Although the use of AES algorithm has already been proposed for the same issue, by contrasting the two algorithms under the parameters of burst encryption and decryption time, end-to-end delay, it was found that RC4 provided better results. This paper looks to provide a better solution for the confidentiality of the burst in OBS networks.

A Systematic Review on Confidentiality, Disclosure, and Stigma in the United States: Lessons for HIV Care in Pregnancy From Reproductive Genetics.

Science.gov (United States)

Wilkinson, Barbara; Arora, Kavita Shah

2015-01-01

The fields of HIV care in pregnancy and reproductive genetics have always been 'exceptional' in that patients are highly concerned about the potential for stigma and the corresponding need for privacy and confidentiality. However, the two fields have diverged in how they have addressed these concerns. The systematic review analyzed 61 manuscripts for similarities and differences between the fields of HIV care in pregnancy and reproductive genetics in the United States, with respect to privacy, confidentiality, disclosure, and stigma. The systematic review revealed that the field of HIV care in pregnancy has insufficiently addressed patient concerns about privacy, confidentiality, and stigma compared to the field of reproductive genetics. Failure to adequately protect confidentiality of HIV-positive patients, and failure to reduce stigma associated with HIV testing and treatment are deficiencies in the delivery of care to HIV-positive pregnant woman and barriers to reducing vertical transmission of HIV. Improvements in care and policy should mirror the field of reproductive genetics.

Gossip, stories and friendship: confidentiality in midwifery practice.

James, S

1995-12-01

Women often seek midwifery care as an alternative to the maternity services that are readily available within the insured health care system in Alberta. Some aspects of community-based, primary care midwifery in Alberta that characterize this alternative are the use of story-telling as a form of knowledge, the development of social connections among women seeking midwifery care, and nonauthoritarian relationships between midwives and women. In this paper, the concept of confidentiality, as it relates to these aspects of midwifery practice, is explored, using traditional, caring and feminist models of ethics.

Using and Disclosing Confidential Patient Information and The English Common Law: What are the Information Requirements of a Valid Consent?

Science.gov (United States)

Chico, Victoria; Taylor, Mark J

2018-02-01

The National Health Service in England and Wales is dependent upon the flow of confidential patient data. In the context of consent to the use of patient health data, insistence on the requirements of an 'informed' consent that are difficult to achieve will drive reliance on alternatives to consent. Here we argue that one can obtain a valid consent to the disclosure of confidential patient data, such that this disclosure would not amount to a breach of the common law duty of confidentiality, having provided less information than would typically be associated with an 'informed consent'. This position protects consent as a practicable legal basis for disclosure from debilitating uncertainty or impracticability and, perhaps counter-intuitively, promotes patient autonomy.

DFT study on the crystal, electronic and magnetic structures of tantalum based double perovskite oxides Ba2MTaO6 (M = Cr, Mn, Fe) via GGA and GGA + U

Science.gov (United States)

Saad, H.-E.; Musa, M.; Elhag, Ahmed

2018-06-01

In this paper, we study the crystal, electronic and magnetic structures of three tantalum based double perovskite oxides Ba2MTaO6 (M = Cr, Mn, Fe). All calculations were performed using the full-potential linear augmented plane-wave (PF-LAPW) method based on the first-principles density functional theory (DFT). For the exchange correlation potential, the generalized gradient approximation (GGA) and GGA plus on-site Coulomb parameter (GGA + U) were employed. The structural optimization reveals that the three compounds are stable in cubic structure (space group Fm-3m; tilt system a0a0a0). The band structure, density of states (DOS), charge density and spin magnetic moments were calculated and analyzed in details. By analysis the band structure and DOS, Ba2MTaO6 exhibits an insulating behavior (M = Cr, Fe) and a half-metallic (HM) nature (M = Mn). GGA + U method yields quite accurate results for the band-gap (Eg) as compared with GGA. We found that all three compounds have stable ferromagnetic (FM) ground state within GGA and GGA + U calculations. The M3+ (3d) ions contribute the majority in the total spin magnetic-moments, while, the empty T5+ (5d) ions carry very small induced magnetic moment via the M (3d)-O (2p)-Ta (5d) hybridization.

Negotiating climate change agreements - the view from the mineral wool sector

International Nuclear Information System (INIS)

Loudon, Robert

2001-01-01

Trade associations representing energy-intensive industrial sectors in the UK have negotiated agreements with the Department of the Environment, Transport and the Regions (DETR) to enable their members to receive an 80% rebate on the climate change levy (CCL) providing they meet agreed energy saving targets. Insulation manufacturing is represented by Eurisol and the Mineral Wool Energy Savings Company (MINESCO). Rock wool and glass wool manufacture uses energy for blending, melting, fiberising, curing, cooling, cutting and packaging. However the mineral wool sector has already made significant improvements in energy efficiency over the last 20 years. Confidentiality issues led to Eurisol appointing consultants to advise on how individual plants could achieve further energy savings. Cadogan Consultants developed a strategy that incorporated both qualitative and quantitative issues and allowed the energy saving potential at each site to be identified. MINESCO agreed energy saving targets with the DETR in December 2000, but much work remains to be done

Full Text Available Research application of DLP-system for protection of confidential information, a methodology for adapting the DLP-system to the specific activities of the organization, comparative analysis of the results of standard and adapted DLP-systems in the Bank. Developed: a technique for analyzing information security events, algorithm for responding to identified events, methodology and procedures for adapting the standard DLP-system to the specifics of the Bank’s activities. The methodology for adapting a standard DLP-system to the specifics of the Bank’s work consists of the following activities: identification of critical corporate information categories, audit of information systems, description of current risks and their assessment, introduction of rules for Bank’s critical information and setting up a DLP system in accordance with the specifics of the Bank’s work. Modernization of the configuration of a standard DLP-system includes the following procedures: selection of confidential information of the Bank based on membership criteria, setting up detection, creating perimeters and developing an algorithm for responding to identified information security events in the Bank. The algorithm is designed to improve the efficiency of the response of information security officers in cases of incident detection and describes the stages of the subsequent actions. The results of the research prove that using an adapted DLP-system significantly reduces the number of false positives, increasing the accuracy of detecting confidential information and reducing the risk of leakage of critical information outside the corporate network. The application of the adapted DLP-system in the Bank allowed to increase the speed of response of information security specialists to the information security events detected by the DLP-system adapted to the Bank, and also allowed the DLP-system to transition from the copy mode to the blocking mode of illegitimate transfer

Law on consent and confidentiality in India: a need for clarity.

Science.gov (United States)

Mathiharan, Karunakaran

2014-01-01

The concept of informed consent specific to medical research and treatment is still alien to many medical researchers and practitioners and to millions of Indians. The doctor-patient relationship in India is governed more by trust where the doctor is the authoritative person. Therefore, the benefit of informed consent does not reach all patients in day-to-day medical practice. To complicate the issue, the Indian law is not specific about the age at which a person can give valid consent. The Indian Penal Code is silent about the legal validity of consent given by persons between 12 and 18 years of age. Similarly, the age at which the 'Right to Confidentiality' begins is yet to be defined either by the statute or by the courts. Hence, there is a need for a clear statutory provision to remove the anomalies and ambiguities regarding the age of consent to undergo invasive therapeutic or investigative procedures, participate in clinical trials, as well as define the age at which a person's right to medical confidentiality begins.

Confidentiality Concerns and Sexual and Reproductive Health Care Among Adolescents and Young Adults Aged 15-25.

Copen, Casey E; Dittus, Patricia J; Leichliter, Jami S

2016-12-01

Data from the National Survey of Family Growth •About 7% of persons aged 15-25 would not seek sexual or reproductive health care because of concerns that their parents might find out about it. •For females aged 15-17 and 18-25, those who had confidentiality concerns were less likely to receive sexual and reproductive health services in the past year compared with those without these concerns. •Less than one-half of teenagers aged 15-17 (38.1%) spent some time alone in the past year during a visit with a doctor or other health care provider without a parent, relative, or guardian in the room. •Teenagers aged 15-17 who spent some time alone during a visit with a health care provider were more likely to have received sexual or reproductive health services in the past year compared with those who had not. Confidentiality concerns can impact adolescent and young adults' access to sexual and reproductive health services (1-4). Young people who are covered by their parents' private health insurance may be deterred from obtaining these services due to concerns that their parents might find out about it (2). Similarly, confidentiality concerns may arise because youth seeking such services may not have time alone during a visit with a health care provider (4).

Pharmaceutical sponsored clinical trials, formerly conducted predominantly in the United States and Europe, have expanded to emerging regions, including the Middle East. Our study explores factors influencing clinical trial privacy and confidentiality in the United Arab Emirates. Factors including concept familiarity, informed consent compliance, data access, and preservation, were analyzed to assess current practices in the Arab world. As the UAE is an emerging region for clinical trials, there is a growing need for regulations related to data confidentiality and subject privacy. Informational and decisional privacy should be viewed within the realms of Arab culture and religious background.

Spatial confidentiality and GIS: re-engineering mortality locations from published maps about Hurricane Katrina

Directory of Open Access Journals (Sweden)

Leitner Michael

2006-10-01

Full Text Available Abstract Background Geographic Information Systems (GIS can provide valuable insight into patterns of human activity. Online spatial display applications, such as Google Earth, can democratise this information by disseminating it to the general public. Although this is a generally positive advance for society, there is a legitimate concern involving the disclosure of confidential information through spatial display. Although guidelines exist for aggregated data, little has been written concerning the display of point level information. The concern is that a map containing points representing cases of cancer or an infectious disease, could be re-engineered back to identify an actual residence. This risk is investigated using point mortality locations from Hurricane Katrina re-engineered from a map published in the Baton Rouge Advocate newspaper, and a field team validating these residences using search and rescue building markings. Results We show that the residence of an individual, visualized as a generalized point covering approximately one and half city blocks on a map, can be re-engineered back to identify the actual house location, or at least a close neighbour, even if the map contains little spatial reference information. The degree of re-engineering success is also shown to depend on the urban characteristic of the neighborhood. Conclusion The results in this paper suggest a need to re-evaluate current guidelines for the display of point (address level data. Examples of other point maps displaying health data extracted from the academic literature are presented where a similar re-engineering approach might cause concern with respect to violating confidentiality. More research is also needed into the role urban structure plays in the accuracy of re-engineering. We suggest that health and spatial scientists should be proactive and suggest a series of point level spatial confidentiality guidelines before governmental decisions are made

Examples of other point maps displaying health data extracted from the academic literature are presented where a similar re-engineering approach might cause concern with respect to violating confidentiality. More research is also needed into the role urban structure plays in the accuracy of re-engineering. We suggest that health and spatial scientists should be proactive and suggest a series of point level spatial confidentiality guidelines before governmental decisions are made which may be reactionary toward the threat of revealing

Beskow, Laura M; Check, Devon K; Ammarell, Natalie

2014-01-01

Certificates of Confidentiality are intended to facilitate participation in critical public health research by protecting against forced disclosure of identifying data in legal proceedings, but little is known about the effect of Certificate descriptions in consent forms. To gain preliminary insights, we conducted qualitative interviews with 50 HIV-positive individuals in Durham, North Carolina to explore their subjective understanding of Certificate descriptions and whether their reactions differed based on receiving a standard versus simplified description. Most interviewees were neither reassured nor alarmed by Certificate information, and most said it would not influence their willingness to participate or provide truthful information. However, compared with those receiving the simplified description, more who read the standard description said it raised new concerns, that their likelihood of participating would be lower, and that they might be less forthcoming. Most interviewees said they found the Certificate description clear, but standard-group participants often found particular words and phrases confusing, while simplified-group participants more often questioned the information's substance. Valid informed consent requires comprehension and voluntariness. Our findings highlight the importance of developing consent descriptions of Certificates and other confidentiality protections that are simple and accurate. These qualitative results provide rich detail to inform a larger, quantitative study that would permit further rigorous comparisons.

Lalanda, Mónica; Altisent, Rogelio; Delgado-Marroquín, Maria Teresa

2018-02-01

At the University of Zaragoza in Spain we developed an innovative way to teach the concept of confidentiality to medical students, which we tested by comparing the use of customized comics with more traditional methods. We proved that using comics is more attractive to students than lectures and class discussions, that it increases class participation and students' self-awareness of learning, and that it maintains the same academic results. We share our experience visually in a two-page comic. © 2018 American Medical Association. All Rights Reserved.

Vibrational infrared and Raman spectra of polypeptides: Fragments-in-fragments within molecular tailoring approach

Energy Technology Data Exchange (ETDEWEB)

Sahu, Nityananda; Gadre, Shridhar R., E-mail: gadre@iitk.ac.in [Department of Chemistry, Indian Institute of Technology Kanpur, Kanpur 208 016 (India)

The present work reports the calculation of vibrational infrared (IR) and Raman spectra of large molecular systems employing molecular tailoring approach (MTA). Further, it extends the grafting procedure for the accurate evaluation of IR and Raman spectra of large molecular systems, employing a new methodology termed as Fragments-in-Fragments (FIF), within MTA. Unlike the previous MTA-based studies, the accurate estimation of the requisite molecular properties is achieved without performing any full calculations (FC). The basic idea of the grafting procedure is implemented by invoking the nearly basis-set-independent nature of the MTA-based error vis-à-vis the respective FCs. FIF has been tested out for the estimation of the above molecular properties for three isomers, viz., β-strand, 3{sub 10}- and α-helix of acetyl(alanine){sub n}NH{sub 2} (n = 10, 15) polypeptides, three conformers of doubly protonated gramicidin S decapeptide and trpzip2 protein (PDB id: 1LE1), respectively, employing BP86/TZVP, M06/6-311G**, and M05-2X/6-31G** levels of theory. For most of the cases, a maximum difference of 3 cm{sup −1} is achieved between the grafted-MTA frequencies and the corresponding FC values. Further, a comparison of the BP86/TZVP level IR and Raman spectra of α-helical (alanine){sub 20} and its N-deuterated derivative shows an excellent agreement with the existing experimental spectra. In view of the requirement of only MTA-based calculations and the ability of FIF to work at any level of theory, the current methodology provides a cost-effective solution for obtaining accurate spectra of large molecular systems.

To Tell, or Not to Tell; Confidentiality in an Iranian HIV Positive Patient: A Viewpoint

Full Text Available Confidentiality is a basic concept in medical ethics and protecting confidentiality is considered as physicians’ duty. In some occasions, this protection is in conflict with the right of the patient’s sexual partner, who should be informed about the possibility of being infected. The sexual partner being pregnant, the situation is going to be more complicated. In this paper, we present a case discussion with special ethical, legal, social, cultural, and religious aspects. According to this informing sexual partner with the patient’s assent, opt-out Human immunodeficiency virus (HIV screening in pregnant women and enhancing psychosocial and family support are highly recommended. Strategic changes in health system policies and regulations seem to be necessary as well.

Wireless Physical Layer Security: On the Performance Limit of Secret-Key Agreement

KAUST Repository

Zorgui, Marwen

2015-05-01

Physical layer security (PLS) is a new paradigm aiming at securing communications between legitimate parties at the physical layer. Conventionally, achieving confidentiality in communication networks relies on cryptographic techniques such as public-key cryptography, secret-key distribution and symmetric encryption. Such techniques are deemed secure based on the assumption of limited computational abilities of a wiretapper. Given the relentless progress in computational capacities and the dynamic topology and proliferation of modern wireless networks, the relevance of the previous techniques in securing communications is more and more questionable and less and less reliable. In contrast to this paradigm, PLS does not assume a specific computational power at any eavesdropper, its premise to guarantee provable security via employing channel coding techniques at the physical layer exploiting the inherent randomness in most communication systems. In this dissertation, we investigate a particular aspect of PLS, which is secret-key agreement, also known as secret-sharing. In this setup, two legitimate parties try to distill a secret-key via the observation of correlated signals through a noisy wireless channel, in the presence of an eavesdropper who must be kept ignorant of the secret-key. Additionally, a noiseless public channel is made available to the legitimate parties to exchange public messages that are also accessible to the eavesdropper. Recall that key agreement is an important aspect toward realizing secure communications in the sense that the key can be used in a one-time pad scheme to send the confidential message. In the first part, our focus is on secret-sharing over Rayleigh fading quasi-static channels. We study the fundamental relationship relating the probability of error and a given target secret-key rate in the high power regime. This is characterized through the diversity multiplexing tradeoff (DMT) concept, that we define for our model and then

To explore parental beliefs and attitudes about confidential services for their teenagers; and to develop an instrument to assess these beliefs and attitudes that could be used among English and Spanish speakers. The long-term goal is to use this research to better understand and evaluate interventions to improve parental knowledge and attitudes toward their adolescent's access and utilization of comprehensive confidential health services. The instrument was developed using an extensive literature review and theoretical framework followed by qualitative data from focus groups and in-depth interviews. It was then pilot tested with a random sample of English- and Spanish-speaking parents and further revised. The final instrument was administered to a random sample of 1,000 mothers. The psychometric properties of the instrument were assessed for Spanish and English speakers. The instrument consisted of 12 scales. Most Cronbach alphas were >.70 for Spanish and English speakers. Fewer items for Spanish speakers "loaded" for the Responsibility and Communication scales. Parental Control of Health Information failed for Spanish speakers. The Parental Attitudes of Adolescent Confidential Health Services Questionnaire (PAACS-Q) contains 12 scales and is a valid and reliable instrument to assess parental knowledge and attitudes toward confidential health services for adolescents among English speakers and all but one scale was applicable for Spanish speakers. More research is needed to understand key constructs with Spanish speakers. Copyright © 2014 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

Contractual obligations and the sharing of confidential health information in sport.

Science.gov (United States)

Anderson, L

2008-09-01

As an employee, a sports doctor has obligations to their employer, but also professional and widely accepted obligations of a doctor to the patient (in this case the individual team member). The conflict is evident when sports doctors are asked by an athlete to keep personal health information confidential from the coach and team management, and yet both doctor and athlete have employment contracts specifying that such information shall be shared. Recent research in New Zealand shows that despite the presence of an employment contract, there appears to be a wide range of behaviours among sports doctors when an athlete requests that information about them be kept from team management. Many seem willing to honour requests to keep health information about the athlete confidential, thereby being in breach of the employment contract, while others insist on informing team management against the wishes of the athlete. There are a number of potential solutions to this dilemma from forcing doctors to meet their contractual obligations, to limiting the expectations of the employment contract. This paper suggests that at times it may be appropriate to do both, making the position of the doctor clearer and supporting the ability of this group to resist pressure by coaches and management through having a robust code of ethics.

Confidentiality in participatory research: Challenges from one study.

Petrova, Elmira; Dewing, Jan; Camilleri, Michelle

2016-06-01

This article presents key ethical challenges that were encountered when conducting a participatory qualitative research project with a very specific, small group of nurses, in this case with practice development nurses in Malta. With the small number of nurses employed in practice development roles in Malta, there are numerous difficulties of maintaining confidentiality. Poorly constructed interventions by the researcher could have resulted in detrimental effects to research participants and the overall trustworthiness of the research. Generally, ethical guidelines for research exist to reinforce validity of research; however, there is not an established consensus on how these strategies can be utilised in some types of qualitative field work. The researcher used an exploratory case study methodology. The sample consisted of 10 participants who were interviewed twice using face-to-face interviews, over a period of 2 months. The study was ethically reviewed by the University Research Ethics Committee and the Faculty Research Ethics Committee, University of Malta. The participants referred to in this article have been given adequate information about the study and their consent has been obtained. Numerous strategies for ensuring confidentiality during recruitment of the participants, during data collection, during transcription and data analysis and during dissemination of research results assisted the researcher in responding to potential and actual ethical issues. This article emphasises the main strategies that can be used to respond to ethical challenges when researching with a small easily identifiable group. The learning discussed here may be relevant to or even transferable to other similar research studies or research contexts. These methods fostered a greater credibility throughout the research process and predisposed the participants to greater trust, and thus, they disclosed their experiences and speak more freely, thus enhancing the quality of the study

THE CONFIDENTIALITY OF THE MEDICAL ACT IN THE DEPRIVATION OF LIBERTY ENVIRONMENT

Laurenţia Florentina GĂIŞTEANU (ŞTEFAN

2018-05-01

Full Text Available Respecting the medical secrecy is one of the essential conditions underlying the protection of private life. Medical information obtained from patients in the context of a physician - patient relationship should be protected by confidentiality. Disclosure of personal health care data without the agreement of the person is a touch brought to private life. One particular feature of the health care system is the healthcare provided to patients in detention. Even though the doctor-patient relationship in the penitentiary environment has a number of peculiarities, it is coordinated according to the same ethical principles as in the public one. The penitentiary physician's duty is not limited to consultation and treatment, he often becomes the prisoner's personal physician, and the means of relationship must respect the fundamental rights of the patient, regardless of his or her status. In the penitentiary system, there are also many dilemmas arising from the duties of the medical staff, the first of the detainee's personal physician and the second of the penitentiary administration's counselor. The medical specialist in a penitentiary must take into account that communicating with the patient is essential in the doctor-patient relationship and she must be sincere. In determining the attitude of the patient towards the doctor and the medical act, the context of the first contact with the doctor, the way in which the first medical consultation takes place, is of great importance. Trust is gradually gaining, and medical staff must strive to demonstrate that they can ensure the protection of prisoners' medical records.

General practitioners' perspectives regarding competence and confidentiality in an adolescent with suspected anorexia nervosa: legal and ethical considerations.

Science.gov (United States)

Bartholomew, Terence P; Paxton, Susan J

2003-02-01

In Victoria, Australia, the legal position regarding young people's competence to make medical treatment decisions has not been clarified in legislation, and a number of often vague common law decisions must be relied on for guidance. This situation produces a degree of uncertainty about appropriate professional practice, while also potentially impeding young people's rights claims in health care settings. With this in mind, the present research explored general practitioners' competence and confidentiality decisions regarding a 17-year-old female who presented with symptoms of an eating disorder. Questionnaires were sent to a random sample of 500 Victorian general practitioners, of whom 190 responded. After reading a case vignette, general practitioners indicated whether they would find the hypothetical patient competent and if they would maintain her confidentiality. Seventy-three per cent of respondents found the patient competent and most would have maintained confidentiality, at least initially. However, subsequent analysis of the rationales supplied for these decisions revealed a wide diversity in general practitioners' understandings and implementations of extant legal authority. This research highlights the need for general practitioners to be exposed to up-to-date and clinically relevant explanations of contemporary legal positions.

There is limited information about the prevalence of unethical behavior and how is perceived among health care providers. The aim of this study is to assess such behavior and how is perceived. This is a cross-sectional study among three groups of professionals. Total participants were 370 and included medical staff, medical residents, and nurses in five medical specialties in four tertiary hospitals in Saudi Arabia (two Ministry of Health Hospitals and two military Hospitals). Participants were asked to rate their agreement with occurrence of 15 "negative" unethical behavior scenarios in their workplace. The scenarios covered areas of "respect for persons", "interprofessional relationships", and "empathy with patients". Majority of respondents agreed that "unethical" behavior occurred in their workplace, including confidentiality being compromised (36.3%), informed consent not taken properly (60.2%), and bad news not well-delivered (62.2%). Other significant area agreement included doctors lacking empathy (47.8%), patient autonomy not fully respected (42.5%), discrimination (41.2%), and being pressurized to write inaccurate reports (31.2%). Respondents in medicine had the lowest rate of agreement and those in psychiatry had the highest (mean of 49.8% and 82.3%, respectively). Respondents with length of employment of less than 6 years had significantly higher agreement that unethical behavior occurs compared to those with length of employment of more than 6 years. Males were more likely than females to agree that unethical behavior occurs. The biggest difference was seen in the behavior of "informed consent not properly taken" with a gender margin of 18.7% (P = 0.001). There is high prevalence of behavior that is considered unethical as perceived by various health care workers at Saudi hospitals.

[When the violation of medical confidentiality is imposed by law: Another side effect of Law N° 20.584].

Science.gov (United States)

Vega, Jorge; Quintana, María Soledad

2016-02-01

A law of rights and duties of patients was recently enacted in Chile (Law N° 20.584). When someone dies, the law allows his inheritors to have access to part or the totality of the medical record. Therefore, they may become acquainted of information that the patient gave in confidence to his physician, protected by "the medical confidentiality". The original bill included the possibility that a doctor could deny information that could cause harm to the former holder of the clinical record, but this precaution was banned by congressmen, seriously damaging the institution of "medical confidentiality", a cornerstone of the medical-patient relationship since the beginning of medicine.

Management of medical confidentiality in English professional football clubs: some ethical problems and issues.

Science.gov (United States)

Waddington, I; Roderick, M

2002-04-01

To examine the ways in which confidential matters are dealt with in the context of the relationship between the club doctor (or physiotherapist) and the player as patient in English professional football clubs. Semistructured tape recorded interviews with 12 club doctors, 10 club physiotherapists, and 27 current and former players. A questionnaire was also sent to 90 club doctors; 58 were returned. There is among club doctors and physiotherapists no commonly held code of ethics governing how much and what kind of information about players may properly be passed on to managers; associated with this, there is considerable variation from one club to another in terms of the amount and kind of information passed on to managers. In some clubs, medical staff attempt to operate more or less on the basis of the rules governing confidentiality that apply in general practice, but in other clubs, medical staff are more ready to pass on personal information about players. In some situations, this raises serious ethical questions. Guidelines dealing with confidentiality in practitioner-patient relationships in medical practice have long been available and have recently been restated, specifically in relation to the practice of sports medicine, by the British Olympic Association, the British Medical Association, and the Football Association. This is a welcome first step. However, if the guidelines are to have an impact on practice, detailed consideration needs to be given to ensuring their effective implementation; if this is to be achieved, consideration also needs to be given to identifying those aspects of the culture and organisation of professional football clubs that may hinder the full and effective implementation of those guidelines.

High-Technology Companies Often Turn to Colleges for Confidential 'Beta Tests' of New Products.

Beta testing--the process of trying a product in a real-world setting before releasing it commercially--exploits a natural interface between universities and high-technology industries. High-tech companies need confidential, real-world tests of new products, and universities are eager to get an early look at tomorrow's technology. (MLW)

Understanding whether and how the places where people live, work, and play are associated with health behaviors and health is essential to understanding the social determinants of health. However, social-spatial data which link a person and their attributes to a geographic location (e.g., home address) create potential confidentiality risks. Despite the growing body of literature describing approaches to protect individual confidentiality when utilizing social-spatial data, peer-reviewed manuscripts displaying identifiable individual point data or quasi-identifiers (attributes associated with the individual or disease that narrow identification) in maps persist, suggesting that knowledge has not been effectively translated into public health research practices. Using sexual and reproductive health as a case study, we explore the extent to which maps appearing in recent peer-reviewed publications risk participant confidentiality. Our scoping review of sexual and reproductive health literature published and indexed in PubMed between January 1, 2013 and September 1, 2015 identified 45 manuscripts displaying participant data in maps as points or small-population geographic units, spanning 26 journals and representing studies conducted in 20 countries. Notably, 56% (13/23) of publications presenting point data on maps either did not describe approaches used to mask data or masked data inadequately. Furthermore, 18% (4/22) of publications displaying data using small-population geographic units included at least two quasi-identifiers. These findings highlight the need for heightened education for researchers, reviewers, and editorial teams. We aim to provide readers with a primer on key confidentiality considerations when utilizing linked social-spatial data for visualizing results. Given the widespread availability of place-based data and the ease of creating maps, it is critically important to raise awareness on when social-spatial data constitute protected health

Controls Mitigating the Risk of Confidential Information Disclosure by Facebook: Essential Concern in Auditing Information Security

Directory of Open Access Journals (Sweden)

Ivan Ognyanov Kuyumdzhiev

2014-08-01

Full Text Available Facebook allows people to easily share information about themselves which in some cases could be classified as confidential or sensitive in the organisation they’re working for. In this paper we discuss the type of data stored by Facebook and the scope of the terms “confidential” and “sensitive data”. The intersection of these areas shows that there is high possibility for confidential data disclosure in organisations with none or ineffective security policy. This paper proposes a strategy for managing the risks of information leakage. We define five levels of controls against posting non-public data on Facebook - security policy, applications installed on employees’ workstations, specific router software or firmware, software in the cloud, Facebook itself. Advantages and disadvantages of every level are evaluated. As a result we propose developing of new control integrated in the social media.

Private business: the uptake of confidential HIV testing in remote aboriginal communities on the Anangu Pitjantjatjara Lands.

Science.gov (United States)

Miller, P J; Torzillo, P J

1998-10-01

Despite a concentration of risk factors for HIV transmission, many remote Aboriginal communities in central Australia have a low uptake of HIV testing. We studied the uptake of HIV testing in six clinics in remote Aboriginal communities following the introduction of voluntary confidential testing to assess the impact of the intervention and to determine if the program was reaching people most at risk of HIV infection and transmission. The study was conducted by Nganampa Health Council, an Aboriginal-controlled health service on the Anangu Pitjantjatjara Lands in the far north-west of South Australia. Since the introduction of confidential coded testing in August 1994 the number of HIV tests provided through the remote clinics has increased from 83 tests/year to 592 tests/year. In the 12-month audit period (August 1, 1995, to July 31, 1996) 62.7% of women aged 20-24 years, 44.6% of people aged 12-40 years and 24% of the total population had an HIV test. Fifty per cent of tests were accounted for by the 15-25 year age groups and 60% of tests related to an STD consult. This study shows that a high uptake of HIV testing in high-risk groups can be achieved in remote Aboriginal communities where a high level of confidentiality is maintained.

A rural/urban comparison of privacy and confidentiality concerns associated with providing sensitive location information in epidemiologic research involving persons who use drugs.

Rudolph, Abby E; Young, April M; Havens, Jennifer R

2017-11-01

Analyses that link contextual factors with individual-level data can improve our understanding of the "risk environment"; however, the accuracy of information provided by participants about locations where illegal/stigmatized behaviors occur may be influenced by privacy/confidentiality concerns that may vary by setting and/or data collection approach. We recruited thirty-five persons who use drugs from a rural Appalachian town and a Mid-Atlantic city to participate in in-depth interviews. Through thematic analyses, we identified and compared privacy/confidentiality concerns associated with two survey methods that (1) collect self-reported addresses/cross-streets and (2) use an interactive web-based map to find/confirm locations in rural and urban settings. Concerns differed more by setting than between methods. For example, (1) rural participants valued interviewer rapport and protections provided by the Certificate of Confidentiality more; (2) locations considered to be sensitive differed in rural (i.e., others' homes) and urban (i.e., where drugs were used) settings; and (3) urban participants were more likely to view providing cross-streets as an acceptable alternative to providing exact addresses for sensitive locations and to prefer the web-based map approach. Rural-urban differences in privacy/confidentiality concerns reflect contextual differences (i.e., where drugs are used/purchased, population density, and prior drug-related arrests). Strategies to alleviate concerns include: (1) obtain a Certificate of Confidentiality, (2) collect geographic data at the scale necessary for proposed analyses, and (3) permit participants to provide intersections/landmarks in close proximity to actual locations rather than exact addresses or to skip questions where providing an intersection/landmark would not obfuscate the actual address.

Confidentiality Issues and Use of Sexually Transmitted Disease Services Among Sexually Experienced Persons Aged 15-25 Years - United States, 2013-2015.

Leichliter, Jami S; Copen, Casey; Dittus, Patricia J

2017-03-10

National-level data are limited regarding confidentiality-related issues and the use of sexually transmitted disease (STD) services for adolescents and young adults. Changes in the U.S. health care system have permitted dependent children to remain on a parent's health insurance plan until the child's 26th birthday and required coverage of certain preventive services, including some STD services, without cost sharing for most plans (1,2). Although these provisions likely facilitate access to the health care system, adolescents and young adults might not seek care or might delay seeking care for certain services because of concerns about confidentiality, including fears that their parents might find out (3,4). Therefore, it is important to examine STD services and confidentiality-related issues among persons aged 15-25 years in the United States. CDC analyzed data from the 2013-2015 National Survey of Family Growth and found that 12.7% of sexually experienced youths (adolescents aged 15-17 years and those young adults aged 18-25 years who were on a parent's insurance plan) would not seek sexual and reproductive health care because of concerns that their parents might find out. Particularly concerned were persons aged 15-17 years (22.6%). Females with confidentiality concerns regarding seeking sexual and reproductive health care reported a lower prevalence of receipt of chlamydia screening (17.1%) than did females who did not cite such concerns (38.7%). More adolescents aged 15-17 years who spent time alone with a health care provider (without a parent in the room) reported receipt of a sexual risk assessment (71.1%) and, among females, chlamydia testing (34.0%), than did those who did not spend time alone (36.6% and 14.9%, respectively). The results indicated that confidentiality-related issues were associated with less reported use of some STD services, especially for younger persons and females. Spending time alone with a provider (i.e., without a parent present

Exploring rater agreement: configurations of agreement and disagreement

Directory of Open Access Journals (Sweden)

ALEXANDER VON EYE

2006-03-01

Full Text Available At the level of manifest categorical variables, a large number of coefficients and models for the examination of rater agreement has been proposed and used for descriptive and explanatory purposes. This article focuses on exploring rater agreement. Configural Frequency Analysis (CFA is proposed as a method of exploration of cross-classifications of raters’ judgements. CFA allows researchers to (1 examine individual cells and sets of cells in agreement tables; (2 examine cells that indicate disagreement; and (3 explore agreement and disagreement among three or more raters. Four CFA base models are discussed. The first is the model of rater agreement that is also used for Cohen’s (1960  (kappa. This model proposes independence of raters’ judgements. Deviations from this model suggest agreement or disagreement beyond chance. The second CFA model is based on a log-linear null model. This model is also used for Brennan and Prediger’s (1981 n. It proposes a uniform distribution of ratings. The third model is that of Tanner and Young (1985. This model proposes equal weights for agreement cases and independence otherwise. The fourth model is the quasi-independence model. This model allows one to blank out agreement cells and thus to focus solely on patterns of disagreement. Examples use data from applicant selection.

Muskat-Gorska, Zuzanna

2008-11-01

The article contextualises an emerging new regime for information privacy in South Africa (i.e. the draft Protection of Personal Information Bill). Subsequently, it discusses the possibility of successful implementation of international data-protection standards in an environment where there is an urgent need to balance HIV/AIDS confidentiality rights with public health requirements. Also, the article presents a preliminary assessment of the possible impact of professionalisation (and outsourcing) of workplace HIV/AIDS management on workplace data-protection practices, and it identifies some spaces for social dialogue on HIV/AIDS-data treatment in South Africa. The study methods comprise an analysis of legal documents (concerning international data-protection standards and the development of law governing data protection and HIV/AIDS confidentiality in South Africa) and interviews conducted with workplace health managers and trade union representatives, in Johannesburg, in 2007.

To determine long-term effects on substance use and substance use disorder (SUD), up to 8 years after childhood enrollment, of the randomly assigned 14-month treatments in the multisite Multimodal Treatment Study of Children with Attention-Deficit/Hyperactivity Disorder (MTA; n = 436); to test whether medication at follow-up, cumulative psychostimulant treatment over time, or both relate to substance use/SUD; and to compare substance use/SUD in the ADHD sample to the non-ADHD childhood classmate comparison group (n = 261). Mixed-effects regression models with planned contrasts were used for all tests except the important cumulative stimulant treatment question, for which propensity score matching analysis was used. The originally randomized treatment groups did not differ significantly on substance use/SUD by the 8-year follow-up or earlier (mean age = 17 years). Neither medication at follow-up (mostly stimulants) nor cumulative stimulant treatment was associated with adolescent substance use/SUD. Substance use at all time points, including use of two or more substances and SUD, were each greater in the ADHD than in the non-ADHD samples, regardless of sex. Medication for ADHD did not protect from, or contribute to, visible risk of substance use or SUD by adolescence, whether analyzed as randomized treatment assignment in childhood, as medication at follow-up, or as cumulative stimulant treatment over an 8-year follow-up from childhood. These results suggest the need to identify alternative or adjunctive adolescent-focused approaches to substance abuse prevention and treatment for boys and girls with ADHD, especially given their increased risk for use and abuse of multiple substances that is not improved with stimulant medication.

In Lithuania, the right to confidentiality in healthcare for adolescents over the age of 16 was guaranteed in 2010 through the adoption of new legislation. This study sets out to explore changes in Lithuanian residents' attitudes towards confidentiality protection in adolescent sexual and reproductive healthcare (SRH) by comparing data from surveys administered in 2005 and 2012. For both surveys, the participants were random samples of the Lithuanian residents aged 16 to 74. A 23-item questionnaire was used in 2005 and complemented with 2 items in 2012. Linear regression analysis was employed to estimate absolute differences in prevalence of belief in whether or not adolescents would find confidentiality important when consulting a physician on SRH issues. A log-binomial regression model was fitted to estimate the relative changes (prevalence ratio) of the independent variables. The total number of respondents was 1054 (response rate 83%) in 2005 and 1002 (response rate 80%) in 2012. The proportion of respondents who reported a belief that adolescents would find confidentiality important when seeing a physician for SRH issues increased significantly from 62% in 2005 to 73% in 2012. Regardless of their belief in the importance of confidentiality, in 2012 respondents more often indicated positive outcomes on the relations between the physician and the minor patient, such as increased trust of the adolescent in the physician and more frequent visits to physicians. However, study participants who believed that adolescents would find confidentiality important in 2012 were less optimistic about potential positive outcomes of further legal consolidation of adolescents' right to confidentiality than in 2005. Younger respondents were the most optimistic about potential outcomes if laws were enacted to further protect adolescent confidentiality. This study uncovers the dynamics of public attitudes towards the socially and ethically sensitive issue of adolescent SRH. Our

They provide assistance to authorized subjects in the sphere of corruption counteraction by giving operative significant information. Thus the article is aimed at the analysis of law enforcement bodies and special services of the USA experience concerning work with confidential sources. The latest tendencies of the US police activities are concentrated on the attraction of citizens to cooperation with police. Such cooperation is efficient in prevention of most hard crimes due to informants' assistance, i.e. people who display desire to cooperate with police. Scientists D. Sunshine and T. Tyler consider that the nature of relations between police and publicity has a great influence on the efficiency of crime counteraction, local citizens' welfare. The authors draw attention to the importance of establishing benevolent relations between police and local population. The given article also reveals the USA law enforcement agencies experience of institute of confidential cooperation using. Using of operative sources of information remains the most efficient tools for detection, suspension, disclosure and investigation of crimes in the whole world. With the aim of achievement of accuracy in terminology it is conducted the identification of different kinds of informants depending on their role and law enforcement institution they collaborate with. Conclusions. Actions in favor of society are a important element of informationship as social institute. The results of conducted analysis testify that the modern understanding of institute of confidential cooperation in the USA is grounded on the following principles: -        the object of message is information about any abuses, violations, immoral behavior that may cause significant violations of rights and duties of citizens

Outsourcing medical data analyses: can technology overcome legal, privacy, and confidentiality issues?

Science.gov (United States)

Brumen, Bostjan; Heričko, Marjan; Sevčnikar, Andrej; Završnik, Jernej; Hölbl, Marko

2013-12-16

Medical data are gold mines for deriving the knowledge that could change the course of a single patient's life or even the health of the entire population. A data analyst needs to have full access to relevant data, but full access may be denied by privacy and confidentiality of medical data legal regulations, especially when the data analyst is not affiliated with the data owner. Our first objective was to analyze the privacy and confidentiality issues and the associated regulations pertaining to medical data, and to identify technologies to properly address these issues. Our second objective was to develop a procedure to protect medical data in such a way that the outsourced analyst would be capable of doing analyses on protected data and the results would be comparable, if not the same, as if they had been done on the original data. Specifically, our hypothesis was there would not be a difference between the outsourced decision trees built on encrypted data and the ones built on original data. Using formal definitions, we developed an algorithm to protect medical data for outsourced analyses. The algorithm was applied to publicly available datasets (N=30) from the medical and life sciences fields. The analyses were performed on the original and the protected datasets and the results of the analyses were compared. Bootstrapped paired t tests for 2 dependent samples were used to test whether the mean differences in size, number of leaves, and the accuracy of the original and the encrypted decision trees were significantly different. The decision trees built on encrypted data were virtually the same as those built on original data. Out of 30 datasets, 100% of the trees had identical accuracy. The size of a tree and the number of leaves was different only once (1/30, 3%, P=.19). The proposed algorithm encrypts a file with plain text medical data into an encrypted file with the data protected in such a way that external data analyses are still possible. The results

A range of codified rules is presented that refer both the welfare of the patient and the maintaining of confidentiality, which is at the heart of trustworthy relations. The 2009 version of the World Anti-Doping Code (WADC), however, appears to oblige all healthcare professionals not to assist athletes if they are known to be engaged in doping behaviours under fear of removal from working with athletes from the respective sports. In contrast, serving the best interests of their athlete patients may oblige healthcare professionals to give advice and guidance, not least in terms of harm minimisation. In so far as the professional conduct of a healthcare professional is guided both by professional code and World Anti-Doping Code, they are obliged to fall foul of one or the other. We call for urgent and pressing inter-professional dialogue with the World Anti-Doping Agency to clarify this situation.

Full Text Available Objectives This study was performed to evaluate the effect of blood contamination on the compressive strength (CS of Root MTA (RMTA modified with Calcium chloride (CaCl2 and Disodium hydrogen phosphate (Na2HPO4 as setting accelerators over time. Materials and Methods A total of 110 cylindrical specimens of RMTA were divided into 6 experimental groups as follows: Group1, RMTA; Group 2, RMTA modified with CaCl2 (RMTA-C; Group 3, RMTA modified with Na2HPO4 (RMTA-N; Group 4, RMTA contaminated with blood; Group 5, RMTA-C contaminated with blood; Group 6, RMTA-N contaminated with blood. The CS of specimens in all groups was evaluated after 3 hr, 24 hr, and 1 wk. In the modified groups (groups 2, 3, 5, and 6 the CS of five specimens per group was also evaluated after 1 hr. Results Blood contamination significantly reduced the CS of all materials at all time intervals (p < 0.05. After 3 hr, the CS of specimens in the RMTA groups (with and without blood contamination was significantly lower than those in the RMTA-C and RMTA-N groups (p < 0.05. The CS values were not significantly different at the other time intervals. In all groups, the CS of specimens significantly increased over time (p < 0.05. Conclusions Blood contamination decreased the CS of both original and accelerated RMTA.

WTO confidential: the case of asbestos.

Castleman, Barry

2003-01-01

The World Trade Organization (WTO), established in 1995, adjudicates "trade disputes" between member nations in cases with human rights, cultural, environmental, and public health significance. Throughout the resolution process and even after a case's conclusion, little of what happens is made accessible to the public. However, it is one thing to criticize the WTO for its lack of transparency from outside the process and another to critically examine what was withheld from disclosure and what dangers that presents. This is the inside story from a scientific adviser to one party in a WTO case, who analyzes what happened from a public health point of view. The analysis concludes that the public health justification for banning asbestos was accepted in the end by WTO economists, despite the WTO's bias in favor of the party (Canada) making the free trade challenge (to public health legislation), despite the WTO's lack of expertise in science, medicine, engineering, and public health, and despite important erroneous statements made to the WTO under the cover of confidentiality. The case nevertheless illustrates that the WTO's threat to national sovereignty could never withstand the light of day if the limitations and dangers of the process were open for all to see.

We introduce the issues around protecting information about patients and related data sent via the Internet. We begin by reviewing three concepts necessary to any discussion about data security in a healthcare environment: privacy, confidentiality, and consent. We are giving some advice on how to protect local data. Authentication and privacy of e-mail via encryption is offered by Pretty Good Privacy (PGP) and Secure Multipurpose Internet Mail Extensions (S/MIME). The de facto Internet standard for encrypting Web-based information interchanges is Secure Sockets Layer (SSL), more recently known as Transport Layer Security or TLS. There is a public key infrastructure process to 'sign' a message whereby the private key of an individual can be used to 'hash' the message. This can then be verified against the sender's public key. This ensures the data's authenticity and origin without conferring privacy, and is called a 'digital signature'. The best protection against viruses is not opening e-mails from unknown sources or those containing unusual message headers.

Medical liability, safety and confidentiality in maritime telemedicine--the MERMAID position on issues of importance.

Ladas, P; Giatagatzidis, P; Anogianakis, G; Maglavera, S

1997-01-01

Telemedicine dates to the days of "wireless telegraphy". As an "extraordinary" arrangement for medical services delivered at time of need, telemedicine has thus far escaped the developments that have taken place over the last 50 years in the areas of medical liability, safety and confidentiality. Today, however, telemedicine is also used to increase quality and cost effectiveness of healthcare provision. This trend is set by the U.S. where the U.S. federal government funds telemedicine at an annual rate of more than $100 million i.e., at a rate 30 times or more than what the EU does while state and local agency support and private business investment in telemedicine is 3 to 4 times larger than that of the U.S. federal government. In this respect it must be stressed that technology tends to satisfy the relevant demand for telecommunications. Telemedicine is used in diverse areas such as pathology, surgery, physical therapy, and psychiatry. It is expected to revolutionise health care in the coming decade and, therefore, it will certainly take into account requirements for medical liability, safety and confidentiality in the same way as traditional "establishment" medicine does.

2017-10-01

Full Text Available This study proposes understanding Agreement and Anti-Agreement in Berber from Multi-Feature Inheritance (MFI account following Branigan’s (2016 recent approach. The study aims to bridge a misunderstanding in the literature where it has been assumed that Feature Inheritance (FI can only account for Agreement relations while Anti-agreement relations can only be established by a direct Agree between C as a probe and its goal. Under MFI, it can be argued that FI can account for all aspects of Agreement/Anti-agreement. The study, therefore, presents a unification of the three mechanisms proposed by Ouali (2008. The new approach is tested on data from Berber.

Medical confidentiality in clinical genetics poses an important question about its scope, which would be in line with professional ethics and simple honesty. It is already known that the maintenance of absolute anonymity, bearing in mind the current progress of genetic techniques, is virtually impossible. On the other hand, our insight into the information contained in the human genome is increasing. This mini-review presents the authors' standpoint regarding this complex and difficult issue.

The aim of the study was to explore the expression and function of MTA2 in NPC.Methods: Expression of MTA2 in NPC tissues and cell lines was detected by immunohistochemistry and Western blotting. Relationship between MTA2 expression and clinicopathological features was analyzed. Stable MTA2-overexpressing and MTA2-siliencing NPC cells were established by transfection with plasmids encoding MTA2 cDNA and lentivirus-mediated short hairpin RNA, respectively. Cell viability was determined by Cell Counting Kit-8 and colony formation assay. Cell migration ability was evaluated by wound healing and transwell invasion assay. The impact of MTA2 knockdown on growth and metastasis of CNE2 cells in vivo was determined by nude mouse xenograft models. Expression of several Akt pathway proteins was detected by Western blotting.Results: MTA2 was upregulated in NPC tissues and three NPC cell lines detected (CNE1, CNE2, and HNE1. MTA2 expression was related to clinical stage and lymph node metastasis of patients with NPC. MTA2 upregulation promoted proliferation and invasion of CNE1 cells, while MTA2 depletion had opposite effects on CNE2 cells. Moreover, MTA2 depletion suppressed growth and metastasis of CNE2 cells in vivo. MTA2 overexpression

Mineral trioxide aggregate induces osteoblastogenesis via Atf6

Full Text Available Mineral trioxide aggregate (MTA has been recommended for various uses in endodontics. To understand the effects of MTA on alveolar bone, we examined whether MTA induces osteoblastic differentiation using MC3T3-E1 cells. MTA enhanced mineralization concomitant with alkaline phosphatase activity in a dose- and time-dependent manner. MTA increased production of collagens (Type I and Type III and matrix metalloproteinases (MMP-9 and MMP-13, suggesting that MTA affects bone matrix remodeling. MTA also induced Bglap (osteocalcin but not Bmp2 (bone morphogenetic protein-2 mRNA expression. We observed induction of Atf6 (activating transcription factor 6, an endoplasmic reticulum (ER stress response transcription factor mRNA expression and activation of Atf6 by MTA treatment. Forced expression of p50Atf6 (active form of Atf6 markedly enhanced Bglap mRNA expression. Chromatin immunoprecipitation assay was performed to investigate the increase in p50Atf6 binding to the Bglap promoter region by MTA treatment. Furthermore, knockdown of Atf6 gene expression by introduction of Tet-on Atf6 shRNA expression vector abrogated MTA-induced mineralization. These results suggest that MTA induces in vitro osteoblastogenesis through the Atf6–osteocalcin axis as ER stress signaling. Therefore, MTA in endodontic treatment may affect alveolar bone healing in the resorbed region caused by pulpal infection.

The apical leakage of mineral trioxide aggregate as the retrograde filling material with various mixing agents

Directory of Open Access Journals (Sweden)

Ema Mulyawati

2010-06-01

Full Text Available Background: Mineral trioxide aggregate (MTA is relatively considered as a new material in endodontic. It even has been used as retrograde filling material due to its biocompatibility, antibacterial effect, sealing ability and anti-moist effect. Some materials have been used as mixing agent to achieve an appropiate setting of MTA. Purpose: The aim of this study is to investigate the effect of the mixing agents of MTA towards the apical leakage when they are used together as retrograde filling materials. Method: The samples of this research consist of 30 human extracted upper central incisors. First, the crown of each tooth is sectioned. The root canals are prepared by using the conventional technique and then are obturated with gutta percha. After cutting the root apex, 2 mm from apical, class 1 cavities are prepared by using fissure bur with the depth of 3 mm. The samples then are divided into 3 groups with 10 teeth for each. Group I uses aquabidest as mixing agent of MTA (MTA-aquabidest, group II uses saline (MTA-saline, while group III uses 0.12% chlorhexidine (MTA-chlorhexidine. The apex of each group then is filled with the mixing MTA determined already. Afterwards, clearing method is used to evaluate the apical leakage. The apical leakage actually is determined by measuring the depth of methylene blue penetration with stereomicroscope. The statictical analyses of the linear dye penetration then are performed with analysis of varians ANOVA. Result: The dye penetration for both MTA-aquadest and MTA-saline groups indicates the lowest penetration, and there is even a significant difference compared with MTA-0.12% chlorhexidine group (p<0.005. Conclusion: It can be concluded that aquabidest and saline as mixing agents of MTA produce less apical leakage compared with 0.12% chlorhexidine.Latar belakang: Mineral trioxide aggregate (MTA merupakan bahan yang relatif baru dalam bidang endodontik.

'Is this knowledge mine and nobody else's? I don't feel that.' Patient views about consent, confidentiality and information-sharing in genetic medicine.

Science.gov (United States)

Dheensa, Sandi; Fenwick, Angela; Lucassen, Anneke

2016-03-01

In genetic medicine, a patient's diagnosis can mean their family members are also at risk, raising a question about how consent and confidentiality should function in clinical genetics. This question is particularly pressing when it is unclear whether a patient has shared information. Conventionally, healthcare professionals view confidentiality at an individual level and 'disclosure without consent' as the exception, not the rule. The relational joint account model, by contrast, conceptualises genetic information as confidential at the familial level and encourages professionals to take disclosure as the default position. In this study, we interviewed 33 patients about consent and confidentiality and analysed data thematically. Our first theme showed that although participants thought of certain aspects of genetic conditions--for example, the way they affect day-to-day health--as somewhat personal, they perceived genetic information--for example, the mutation in isolation--as familial. Most thought these elements were separable and thought family members had a right to know the latter, identifying a broad range of harms that would justify disclosure. Our second theme illustrated that participants nonetheless had some concerns about what, if any, implications there would be of professionals treating such information as familial and they emphasised the importance of being informed about the way their information would be shared. Based on these results, we recommend that professionals take disclosure as the default position, but make clear that they will treat genetic information as familial during initial consultations and address any concerns therein.

A Novel QKD-based Secure Edge Router Architecture Design for Burst Confidentiality in Optical Burst Switched Networks

Science.gov (United States)

Balamurugan, A. M.; Sivasubramanian, A.

2014-06-01

The Optical Burst Switching (OBS) is an emergent result to the technology issue that could achieve a viable network in future. They have the ability to meet the bandwidth requisite of those applications that call for intensive bandwidth. The field of optical transmission has undergone numerous advancements and is still being researched mainly due to the fact that optical data transmission can be done at enormous speeds. The concept of OBS is still far from perfection facing issues in case of security threat. The transfer of optical switching paradigm to optical burst switching faces serious downfall in the fields of burst aggregation, routing, authentication, dispute resolution and quality of service (QoS). This paper proposes a framework based on QKD based secure edge router architecture design to provide burst confidentiality. The QKD protocol offers high level of confidentiality as it is indestructible. The design architecture was implemented in FPGA using diverse models and the results were taken. The results show that the proposed model is suitable for real time secure routing applications of the Optical burst switched networks.

Full Text Available There are two considerations for direct pulp capping - accidental mechanical pulp exposure and exposure caused by caries. Mineral trioxide aggregate (MTA was used as pulp-capping material to preserve the vitality of the pulpal tissues. Follow-up examinations revealed that treatment was successful in preserving pulpal vitality and continued development of the tooth. On the basis of available information, it appears that MTA is the material of choice for some clinical applications. Material and methods: Cases 18 - 8 teeth with grey MTA, 10 teeth with white MTA; diagnose: Pulpitis chronica ulcerosa, Electro pulpal test (EOD - 30-35 μA, pre-clinical X-ray - without changes in the structures, follow ups for 4 years. Successful treatments: without clinical symptoms and changes in the X-rays: 5 teeth with grey MTA, 8 teeth with white MTA for period of 4 years. Unsuccessful treatments: Clinical symptoms and sometimes changes in the X-ray: 3 with grey MTA, 2 with white MTA. MTA is an appropriate material for pulp-capping and follow-up examinations revealed that the treatment was successful in preserving pulpal vitality.

Interpretation of Landscape Scale SWAT Model Outputs in the Western Lake Erie Basin: Potential Implications for Conservation Decision-Making

There is substantial interest in understanding how conservation practices and agricultural management impact water quality, particularly phosphorus dynamics, in the Western Lake Erie Basin (WLEB). In 2016, the US and Canada accepted total phosphorus (TP) load targets recommended by the Great Lakes Water Quality Agreement Annex 4 Objectives and Targets Task Team; these were 6,000 MTA delivered to Lake Erie and 3,660 MTA delivered to WLEB. Outstanding challenges include development of metrics to determine achievement of these goals, establishment of sufficient monitoring capacity to assess progress, and identification of appropriate conservation practices to achieve the most cost-effective results. Process-based modeling can help inform decisions to address these challenges more quickly than can system observation. As part of the NRCS-led Conservation Effects Assessment Project (CEAP), the Soil Water Assessment Tool (SWAT) was used to predict impacts of conservation practice adoption reported by farmers on TP loss and load delivery dynamics in WLEB. SWAT results suggest that once the conservation practices in place in 2003-06 and 2012 are fully functional, TP loads delivered to WLEB will average 3,175 MTA and 3,084 MTA, respectively. In other words, SWAT predicts that currently adopted practices are sufficient to meet Annex 4 TP load targets. Yet, WLEB gauging stations show Annex 4 goals are unmet. There are several reasons the model predictions and current monitoring efforts are not in agreement: 1. SWAT assumes full functionality of simulated conservation practices; 2. SWAT does not simulate changing management over time, nor impacts of past management on legacy loads; 3. SWAT assumes WLEB hydrological system equilibrium under simulated management. The SWAT model runs used to construct the scenarios that informed the Annex 4 targets were similarly constrained by model assumptions. It takes time for a system to achieve equilibrium when management changes and it

The iMTA Productivity Cost Questionnaire: A Standardized Instrument for Measuring and Valuing Health-Related Productivity Losses.

Productivity losses often contribute significantly to the total costs in economic evaluations adopting a societal perspective. Currently, no consensus exists on the measurement and valuation of productivity losses. We aimed to develop a standardized instrument for measuring and valuing productivity losses. A group of researchers with extensive experience in measuring and valuing productivity losses designed an instrument suitable for self-completion, building on preknowledge and evidence on validity. The instrument was designed to cover all domains of productivity losses, thus allowing quantification and valuation of all productivity losses. A feasibility study was performed to check the questionnaire's consistency and intelligibility. The iMTA Productivity Cost Questionnaire (iPCQ) includes three modules measuring productivity losses of paid work due to 1) absenteeism and 2) presenteeism and productivity losses related to 3) unpaid work. Questions for measuring absenteeism and presenteeism were derived from existing validated questionnaires. Because validated measures of losses of unpaid work are scarce, the questions of this module were newly developed. To enhance the instrument's feasibility, simple language was used. The feasibility study included 195 respondents (response rate 80%) older than 18 years. Seven percent (n = 13) identified problems while filling in the iPCQ, including problems with the questionnaire's instructions and routing (n = 6) and wording (n = 2). Five respondents experienced difficulties in estimating the time that would be needed for other people to make up for lost unpaid work. Most modules of the iPCQ are based on validated questions derived from previously available instruments. The instrument is understandable for most of the general public.

Based on their different mechanisms of action, non-overlapping side effects and radiosensitising potential, combining the antimetabolites pemetrexed (multitargeted antifolate, MTA) and gemcitabine (2',2'-difluorodeoxycytidine, dFdC) with irradiation (RT) seems promising. This in vitro study, for the first time, presents the triple combination of MTA, dFdC and irradiation using various treatment schedules. The cytotoxicity, radiosensitising potential and cell cycle effect of MTA were investigated in A549 (NSCLC) and CAL-27 (SCCHN) cells. Using simultaneous or sequential exposure schedules, the cytotoxicity and radiosensitising effect of 24 h MTA combined with 1 h or 24 h dFdC were analysed. Including a time interval between MTA exposure and irradiation seemed favourable to MTA immediately preceding or following radiotherapy. MTA induced a significant S phase accumulation that persisted for more than 8 h after drug removal. Among different MTA/dFdC combinations tested, the highest synergistic interaction was produced by 24 h MTA followed by 1 h dFdC. Combined with irradiation, this schedule showed a clear radiosensitising effect. Results from our in vitro model suggest that the sequence 24 h MTA → 1 h dFdC → RT is the most rational design and would, after confirmation in an in vivo setting, possibly provide the greatest benefit in the clinic

Here we show that expression of MTA3 inhibits ductal branching in virgin and pregnant murine transgenic mammary glands. MTA3 also suppresses the Wnt4 pathway and, thus, these findings parallel phenotypic changes in Wnt4-null mice. MTA3 represses Wnt4 transcription and Wnt4 secretion, inhibiting Wnt-target genes in mammary epithelial cells. Accordingly, knockdown of endogenous MTA3 stimulates Wnt4 expression and Wnt cellular targets. The MTA3–NuRD (nucleosome remodeling and deacetylase) comple...

Mineral trioxide aggregate promotes the odonto/osteogenic differentiation and dentinogenesis of stem cells from apical papilla via nuclear factor kappa B signaling pathway.

Mineral trioxide aggregate (MTA) has been widely used in clinical apexification and apexogenesis. However, the effects of MTA on the stem cells from apical papilla (SCAPs) and the precise mechanism of apexogenesis have not been elucidated in detail. Multiple colony-derived stem cells were isolated from the apical papillae, and the effects of MTA on the proliferation and differentiation of SCAPs were investigated both in vitro and in vivo. Activation of nuclear factor kappa B (NFκB) pathway in MTA-treated SCAPs was analyzed by immunofluorescence assay and Western blot. MTA at the concentration of 2 mg/mL did not affect the proliferation activity of SCAPs. However, 2 mg/mL MTA-treated SCAPs presented the ultrastructural changes, up-regulated alkaline phosphatase, increased calcium deposition, up-regulated expression of odontoblast markers (dentin sialoprotein and dentin sialophosphoprotein) and odonto/osteoblast markers (runt-related transcription factor 2 and osteocalcin), suggesting that MTA enhanced the odonto/osteoblastic differentiation of SCAPs in vitro. In vivo results confirmed that MTA can promote the regular dentinogenesis of SCAPs. Moreover, MTA-treated SCAPs exhibited the up-regulated cytoplasmic phos-IκBα and phos-P65, enhanced nuclear P65, and increased nuclear translocation of P65. When co-treated with BMS345541 (the specific NFκB inhibitor), MTA-mediated odonto/osteoblastic differentiation was significantly attenuated. MTA at the concentration of 2 mg/mL can improve the odonto/osteogenic capacity of SCAPs via the activation of NFκB pathway. Copyright © 2014 American Association of Endodontists.

Inter-jurisdictional cooperation on pharmaceutical product listing agreements: views from Canadian provinces

Directory of Open Access Journals (Sweden)

Morgan Steven G

2013-01-01

Full Text Available Abstract Background Confidential product listing agreements (PLAs negotiated between pharmaceutical manufacturers and individual health care payers may contribute to unwanted price disparities, high administrative costs, and unequal bargaining power within and across jurisdictions. In the context of Canada’s decentralized health system, we aimed to document provincial policy makers’ perceptions about collaborative PLA negotiations. Methods We conducted semi-structured telephone interviews with a senior policy maker from nine of the ten Canadian provinces. We conducted a thematic analysis of interview transcripts to identify benefits, drawbacks, and barriers to routine collaboration on PLA negotiations. Results Canadian policy makers expressed support for joint negotiations of PLAs in principle, citing benefits of increased bargaining power and reduced inter-jurisdictional inequities in drug prices and formulary listings. However, established policy institutions and the politics of individual jurisdictional authority are formidable barriers to routine PLA collaboration. Achieving commitment to a joint process may be difficult to sustain among heterogeneous and autonomous partners. Conclusions Though collaboration on PLA negotiation is an extension of collaboration on health technology assessment, it is a very significant next step that requires harmonization of the outcomes of decision-making processes. Views of policy makers in Canada suggest that sustaining routine collaborations on PLA negotiations may be difficult unless participating jurisdictions have similar policy institutions, capacities to implement coverage decisions, and local political priorities.

Eavesdropping-aware routing and spectrum allocation based on multi-flow virtual concatenation for confidential information service in elastic optical networks

2018-01-01

The leakage of confidential information is one of important issues in the network security area. Elastic Optical Networks (EON) as a promising technology in the optical transport network is under threat from eavesdropping attacks. It is a great demand to support confidential information service (CIS) and design efficient security strategy against the eavesdropping attacks. In this paper, we propose a solution to cope with the eavesdropping attacks in routing and spectrum allocation. Firstly, we introduce probability theory to describe eavesdropping issue and achieve awareness of eavesdropping attacks. Then we propose an eavesdropping-aware routing and spectrum allocation (ES-RSA) algorithm to guarantee information security. For further improving security and network performance, we employ multi-flow virtual concatenation (MFVC) and propose an eavesdropping-aware MFVC-based secure routing and spectrum allocation (MES-RSA) algorithm. The presented simulation results show that the proposed two RSA algorithms can both achieve greater security against the eavesdropping attacks and MES-RSA can also improve the network performance efficiently.

This study tested whether a mood tracking and alert (MTA) mobile application (app) improved mental health care delivery in a high-risk obstetric population. Pregnant women with depressive symptomatology at <32 weeks gestation were followed for eight weeks after randomization to a control patient portal (PP) app alone or with the MTA app. The MTA app monitored activity, assessed mood, and alerted obstetric providers of signs of worsening mood. Seventy-two women enrolled (PP, N=24; MTA, N=48). MTA users had significantly more contacts addressing mental health, and as gestational age increased, they rated ability to manage their own health significantly better than women in the control group. Women who received telephone contact from a provider triggered by an MTA app alert were significantly more likely to receive a mental health specialist referral. A mobile MTA app improved service delivery and patient engagement among patients with perinatal depression symptoms.

Full Text Available In this study the sol-gel process was used to synthesize a precursor mixture for the preparation of silicate cement, also called mineral trioxide aggregate (MTA cement. This mixture was thermally treated under two different conditions (1400 °C/2 h and 1450 °C/3 h followed by rapid cooling in air. The resulted material (clinker was ground for one hour in a laboratory planetary mill (v = 150 rot/min, in order to obtain the MTA cements. The setting time and mechanical properties, in vitro induction of apatite formation by soaking in simulated body fluid (SBF and cytocompatibility of the MTA cements were assessed in this study. The hardening processes, nature of the reaction products and the microstructural characteristics were also investigated. The anhydrous and hydrated cements were characterized by different techniques e.g., X-ray diffraction (XRD, scanning electron microscopy (SEM, infrared spectroscopy (FT-IR and thermal analysis (DTA-DTG-TG. The setting time of the MTA cement obtained by thermal treatment at 1400 °C/2 h (MTA1 was 55 min and 15 min for the MTA cement obtained at 1450 °C/3 h (MTA2. The compressive strength values were 18.5 MPa (MTA1 and 22.9 MPa (MTA2. Both MTA cements showed good bioactivity (assessed by an in vitro test, good cytocompatibility and stimulatory effect on the proliferation of cells.

Electronic medical records containing confidential information were uploaded to the cloud. The cloud allows medical crews to access and manage the data and integration of medical records easily. This data system provides relevant information to medical personnel and facilitates and improve electronic medical record management and data transmission. A structure of cloud-based and patient-centered personal health record (PHR) is proposed in this study. This technique helps patients to manage their health information, such as appointment date with doctor, health reports, and a completed understanding of their own health conditions. It will create patients a positive attitudes to maintain the health. The patients make decision on their own for those whom has access to their records over a specific span of time specified by the patients. Storing data in the cloud environment can reduce costs and enhance the share of information, but the potential threat of information security should be taken into consideration. This study is proposing the cloud-based secure transmission mechanism is suitable for multiple users (like nurse aides, patients, and family members).

This paper surveys the application of game theory to the economic analysis of international fisheries agreements. The relevance of this study comes not only from the existence of a vast literature on the topic but especially from the specific features of these agreements. The emphasis of the survey...... is on coalition games, an approach that has become prominent in the fisheries economics literature over the last decade. It is shown that coalition games were first applied to international fisheries agreements in the late 1990s addressing cooperative issues under the framework of characteristic function games...... and stability of international fisheries agreements. A key message that emerges from this literature strand is that self-enforcing cooperative management of internationally shared fish stocks is generally difficult to achieve.

Full Text Available Background: As increasing amounts of personal information are being collected through a plethora of electronic modalities by statutory and non-statutory organizations, ensuring the confidentiality and security of such information has become a major issue globally. While the use of many of these media can be beneficial to individuals or populations, they can also be open to abuse by individuals or statutory and non-statutory organizations. Recent examples include collection of personal information by national security systems and the development of national programs like the Chinese Social Credit System. In many low- and middle-income countries, an increasing amount of personal health information is being collected. The collection of personal health information is necessary, in order to develop longitudinal medical records and to monitor and evaluate the use, cost, outcome, and impact of health services at facility, sub-national, and national levels. However, if personal health information is not held confidentially and securely, individuals with communicable or non-communicable diseases (NCDs may be reluctant to use preventive or therapeutic health services, due to fear of being stigmatized or discriminated against. While policymakers and other stakeholders in these countries recognize the need to develop and implement policies for protecting the privacy, confidentiality and security of personal health information, to date few of these countries have developed, let alone implemented, coherent policies.

Understanding mineral trioxide aggregate/Portland-cement: a review of literature and background factors.

Science.gov (United States)

Steffen, R; van Waes, H

2009-06-01

This was to carry out a review of the literature concerning mineral trioxide aggregate (MTA) and Portland cement with regards to clinical, biological and mechanical findings and a possible substitution of MTA through Portland cement for endodontic use. Electronic literature search of scientific papers from January 1993 to January 2009 was carried out on the MEDLINE and Scopus databases using specific key words. In total, 57 papers were identified that dealt with MTA and Portland cement in a relevant way. The review of 50 papers conforming to the applied criteria showed that MTA and Portland cements have the same clinical, biological and mechanical properties. In animal experiments and technical characterisations both materials seemed to have very similar properties. The only difference is bismuth oxide in MTA added for better radio opacity. It seems likely that MTA materials are based on industrial Portland cements mixed with bismuth oxide. More studies, especially some long-term studies comparing MTA and Portland cement, are necessary. The existing literature gives a solid base for clinical studies with Portland cement in order to replace MTA as an endodontic material. Portland cement could be a substitute for most endodontic materials used in primary teeth.

2012-02-01

Respecting and protecting the confidentiality of data and the privacy of individuals regarding the information that they have given as participants in a research project is a cornerstone of complying with accepted research standards. However, in longitudinal studies, establishing and maintaining privacy is often challenging because of the necessity of repeated contact with participants. A novel internet-based solution is introduced here, which maintains privacy while at the same time ensures linkage of data to individual participants in a repeated measures design. With the use of the anonymous repeated measurements via email (ARME) procedure, two separate one-way communication systems are established through ad hoc email accounts and a secure study website. Strengths and limitations of the approach are discussed.

2011-01-01

An unsuccessful attempt to reach the apical area or to place the retrograde material is a major difficulty in periradicular surgery. The aim of this study was to compare the histological evaluation of the healing process following an orthograde versus a retrograde application of mineral trioxide aggregate (MTA) as a root-end filling material during apical surgery on cats' teeth in order to find out whether orthograde placement of MTA before surgery can be used instead of retrograde placement during surgery. In this experimental study, 24 canine teeth in 12 mature and healthy cats were filled with either MTA or gutta-percha in an orthograde manner. Two weeks later, the teeth with MTA were surgically exposed and resected to the set-MTA within the canals. The teeth previously filled by gutta-percha were also surgically exposed, and retrograde cavities were prepared at the root ends and filled with fresh-MTA. After 8 weeks, the animals were euthanized by vital perfusion. Six-micron histological slices were prepared from samples, stained by Hematoxylin & Eosin, and histologically studied by means of a light microscope. The collected data was analyzed by the Chi-square and the T-test. One of the samples in the fresh-MTA group was omitted during processing because of inappropriate sectioning. In the set-MTA group, 5 out of 12 showed chronic abscess, while in the fresh-MTA group, 2 out of 11 were discovered to have chronic abscess; however, no significant difference was observed (P>.05). Hard tissue healing (cementum, bone, cementum + bone formation) in the set-MTA and fresh-MTA groups were 7 out of 12 and 9 out of 11, respectively. While healing seemed more likely to occur in the fresh-MTA group, the difference was statistically insignificant (P>.05). The magnitude of bone, cementum, or bone and cementum formation showed slight differences between the two groups; however, the figures failed to show any marked differences (P>.05). Orthograde placement of MTA could be used

A juridical review of partnership agreements that have the elements of work agreements in Indonesia

Nugroho, A.; Sulistyowati, E.; Hikmah, N.

2018-01-01

The Partnership Agreements place the parties in an equal position each party has something as the bargaining power. In some cases, employers prefer to use Partnership Agreements to some individuals to complete the work in their company than Work agreements. Practicality and the absence of obligations to fulfil workers’ rights such as the right to join a Union and to get social security are some of the reasons why employers use the Partnership Agreements. Sometimes Partnership Agreement contains jobs, wages and orders which is the characteristic of work agreement. Based on the fact above, the legal issues arise whether the Partnership Agreement can be considered as the Work Agreement or not and which court is authorized to hear in the event of a dispute. To analyze the above legal issues, this research uses normative legal research type with the statute approach. The technique of legal material analysis uses prescriptive techniques to assess the issue and make recommendations. Based on the analysis, it can be concluded that the Partnership Agreement, of which the elements are: wages and orders can be categorized as Work Agreement and therefore in the event of a dispute, the authorized court is Industrial Relations Court.

Voluntary agreements in environmental policy

International Nuclear Information System (INIS)

Torvanger, Asbjoern

2001-01-01

A typically voluntary agreement is signed between the authorities and an industrial sector in order to reduce the emission of environmentally harmful substances. There are many different types of agreements. Voluntary agreements are not strictly voluntary, since in the background there is often some kind of ''threat'' about taxation or fees if the industry is unwilling to cooperate. This type of agreements has become popular in many OECD countries during the last decades. In Norway there are only a few agreements of this type. Experience with the use of voluntary agreements as well as research show that they are less cost-effective than market-based instruments such as taxes and quota systems. If there are great restrictions on the use of taxes and quota systems because of information- or measurement problems, or because these instruments are not politically acceptable, then voluntary agreements may be an interesting alternative. Thus, voluntary agreements are best used as a supplement to other instruments in some niche areas of the environmental policy. In some cases, voluntary agreements may be used between two countries or at a regional level, for example within the EU

Nuclear exports. Parliamentary control and confidentiality

International Nuclear Information System (INIS)

Feldmann, Ulrike

2015-01-01

With its decision taken on 21. October 2014 (Az.: 2 BvE 5/11) the Federal Constitutional Court (BVerfG) decided during court proceedings between administrative bodies on the scope and limits of the parliamentary right of information. Even though the proceeding did not deal with nuclear exports but arm exports, foreign trade law, however, does not only designate an export licence obligation for military weapons but also for so called dual-use goods meaning goods, which can be used both for friendly as well as for military purposes. The export of these goods requires according to the so-called Dual-Use Regulation (EG) 428/2009 a licence. Annex I category 0 of the regulation (EG) 428/2009 lists a variety of nuclear materials, plants and equipment items for which this licence applies. In the same manner as arm exports, also exports of nuclear dual-use goods are being discussed in a special cabinet committee, the Federal Security Council (BSR), which shall coordinate cross-departmentally the German security and defence policy under consideration of economic interests and which categorises its results, according to the rules of procedure, as confidential. Also legally not regulated but common ''preliminary enquiries'' at the responsible Federal Ministry or rather Federal Office of Economics and Export Control by companies which plan an export and want to affirm the general approval for their export business prior to conclusion of contract take not only place for arm exports but also for nuclear dual-use goods. The decision by the Federal Constitutional Court can be applied to consultations about the authorisation of nuclear dual-use goods.

Nowadays, the interest in real-time services, like audio and video, is growing. These services are mostly transmitted over packet networks, which are based on IP protocol. It leads to analyses of these services and their behavior in such networks which are becoming more frequent. Video has become the significant part of all data traffic sent via IP networks. In general, a video service is one-way service (except e.g. video calls) and network delay is not such an important factor as in a voice service. Dominant network factors that influence the final video quality are especially packet loss, delay variation and the capacity of the transmission links. Analysis of video quality concentrates on the resistance of video codecs to packet loss in the network, which causes artefacts in the video. IPsec provides confidentiality in terms of safety, integrity and non-repudiation (using HMAC-SHA1 and 3DES encryption for confidentiality and AES in CBC mode) with an authentication header and ESP (Encapsulating Security Payload). The paper brings a detailed view of the performance of video streaming over an IP-based network. We compared quality of video with packet loss and encryption as well. The measured results demonstrated the relation between the video codec type and bitrate to the final video quality.

Dating and Sexual Violence Research in the Schools: Balancing Protection of Confidentiality with Supporting the Welfare of Survivors.

Science.gov (United States)

Sharkey, Jill D; Reed, Lauren A; Felix, Erika D

2017-12-01

Rigorous research and program evaluation are needed to understand the experience of dating and sexual violence among youth and the impact of prevention and intervention efforts. Our dilemma in doing this work occurred when youth disclosed dating and sexual violence on a research survey. What responsibility do researchers have to protect survivors' confidentiality as a research participant versus taking steps to ensure the student has the opportunity to access help? In our evaluation of a pilot dating violence prevention program, our protocols employed widely used procedures for providing resources to participants upon their completion of the survey and de-identifying survey data. Upon reviewing preliminary survey results, we became concerned that these established procedures were not sufficient to support research participants who were adolescent survivors of dating and sexual violence. We followed a structured ethical decision-making process to examine legal and ethical considerations, consult with colleagues, consider impacts and alternative solutions, and ultimately find a solution. Through this process, we developed procedures that balance participant confidentiality and the desire to support the welfare of survivors, which other researchers may want to employ when conducting youth sexual and dating violence research in school and community settings. © Society for Community Research and Action 2017.

Social media applications such as Twitter, YouTube and Facebook have attained huge popularity, with more than three billion people and organizations predicted to have a social networking account by 2015. Social media offers a rapid avenue of communication with the public and has potential benefits for communicable disease control and surveillance. However, its application in everyday public health practice raises a number of important issues around confidentiality and autonomy. We report here a case from local level health protection where the friend of an individual with meningococcal septicaemia used a social networking site to notify potential contacts.

The findings of the research showed that the socio-religious interaction of MTA members with Tegalsari villagers created religious social conflict. This conflict came from different understanding of the sources of Islamic law (fiqh. MTA uses textual aproach to resolve the law by ignoring the sociological historical aspects. MTA rejects the use of local cultural jurisprudence in the codification of Islamic law, because they regard some activities such as tahlilan, death-related ceremonies, and slametan are bid’ah. The main root of the conflict is the MTA truth claim and its insentive and inappropriate method of preaching. MTA does not accept the truth  of others.Keywords: Tegalsari, MTA, conflict, truth claimAbstrAkPenelitian ini dilatarbelakangi oleh maraknya aksi penolakan masyarakat terhadap Majelis Tafsir Al-Quran (MTA di beberapa wilayah di Jawa Tengah.

Tran, Kim; Morra, Dante; Lo, Vivian; Quan, Sherman D; Abrams, Howard; Wu, Robert C

2014-05-22

Smartphones are becoming ubiquitous in health care settings. The increased adoption of mobile technology such as smartphones may be attributed to their use as a point-of-care information source and to perceived improvements in clinical communication and efficiency. However, little is known about medical students' use of personal smartphones for clinical work. The intent of the study was to examine final-year medical students' experience with and attitudes toward using personal mobile technology in the clinical environment, with respect to the perceived impact on patient confidentiality and provider professionalism. Cross-sectional surveys were completed by final-year medical students at the University of Toronto. Respondents were asked about the type of personal mobile phone they use, security features on their personal phone, experiences using their personal phone during clinical rotations, and attitudes about using their personal phone for clinical work purposes. The overall response rate was 45.4% (99/218). Smartphone ownership was prevalent (98%, 97/99) with the majority (86%, 85/99) of participants using their personal phones for patient-related communication during clinical rotations. A total of 26% (26/99) of participants reported not having any type of security feature on their personal phone, 94% (90/96) of participants agreed that using their personal phone for clinical work makes them more efficient, and 86% (82/95) agreed that their personal phone allows them to provide better patient care. Although 68% (65/95) of participants believe that the use of personal phones for patient-related communication with colleagues poses a risk to the privacy and confidentiality of patient health information, 22% (21/96) of participants still use their personal phone to text or email identifiable patient data to colleagues. Our findings suggest that the use of personal smartphones for clinical work by medical students is prevalent. There is a need to more fully address

2003-05-01

This article describes a generic model for access to samples and information in human genetic databases. The model utilises a "GeneTrustee", a third-party intermediary independent of the subjects and of the investigators or database custodians. The GeneTrustee model has been implemented successfully in various community genetics screening programs and has facilitated research access to genetic databases while protecting the privacy and confidentiality of research subjects. The GeneTrustee model could also be applied to various types of non-conventional genetic databases, including neonatal screening Guthrie card collections, and to forensic DNA samples.
