Collection of the BD SurePath Pap Test with a broom device plus endocervical brush improves disease detection when compared to the broom device alone or the spatula plus endocervical brush combination
Davis-Devine Sharon,Day Sarah,Anderson Amy,French Ashley
CytoJournal , 2009,
Abstract: Objective: Here we examine the diagnostic utility of the US Food And Drug Administration (FDA) approved Spatula + endocervical brush combination for the BD SurePath Pap Test (SPPT) and compare it to SPPT collection with the broom alone or to an off-label combination of broom + EC brush. This question is important due to lingering concerns over the value of EC detection to a satisfactory Pap test. Methods: 20,125 SPPT vials were examined for the collection devices contained. The SPPT collection device combinations allowed were: Rovers Cervex-Brush (broom, FDA approved), Medscand Pap Perfect Spatula + Medscand CytoBrush Plus GT (spatula + GT brush, FDA approved) or Rovers Cervex-Brush + Surgipath C-E Brush (broom + CE brush, off label). Results: Examination of SPPT vials revealed 11,130 collected with the broom, 4,687 collected with the spatula + GT brush and 2,921 collected with the broom + CE brush. Absence of an endocervical/transformation zone was seen in 22.86% of broom cases, 13.10% of spatula + GT brush cases (p= 0.00005 vs broom) and 10.17% of broom + CE brush cases (p= 0.00005 vs broom, p= 0.00005 vs spatula + GT brush). Importantly, LSIL detection was: broom 2.99%; spatula + GT brush 2.45% (p= 0.053 vs broom); broom + CE brush 4.18% (p= 0.034 vs broom, p= 0.0001 vs spatula + GT brush). Conclusion: When broom + brush combination is compared to broom alone or to spatula + GT brush, the broom + CE brush combination better sampled the endocervical/transformation zone and increased LSIL detection.

Nutrition Journal , 2007, DOI: 10.1186/1475-2891-6-12
Abstract: Ninety-six generally healthy overweight or obese women (ages 25–50 years; BMI 25–35 kg/m2) were randomized into a Traditional Food group (TFG) or a Meal Replacement Group (MRG) incorporating 1–2 meal replacement drinks or bars per day. Both groups had an energy-restricted goal of 5400 kJ/day. Dietary intake data was obtained using 3-Day Food records kept by the subjects at baseline, 6 months and one-year. For more uniform comparisons between groups, each diet intervention consisted of 18 small group sessions led by the same Registered Dietitian.Weight loss for the 73% (n = 70) completing this one-year study was not significantly different between the groups, but was significantly different (p ≤ .05) within each group with a mean (± standard deviation) weight loss of -6.1 ± 6.7 kg (TFG, n = 35) vs -5.0 ± 4.9 kg (MRG, n = 35). Both groups had macronutrient (Carbohydrate:Protein:Fat) ratios that were within the ranges recommended (50:19:31, TFG vs 55:16:29, MRG). Their reported reduced energy intake was similar (5729 ± 1424 kJ, TFG vs 5993 ± 2016 kJ, MRG). There was an improved dietary intake pattern in both groups as indicated by decreased intake of saturated fat (≤ 10%), cholesterol (<200 mg/day), and sodium (< 2400 mg/day), with increased total servings/day of fruits and vegetables (4.0 ± 2.2, TFG vs 4.6 ± 3.2, MRG). However, the TFG had a significantly lower dietary intake of several vitamins and minerals compared to the MRG and was at greater risk for inadequate intake.In this one-year university-based intervention, both dietitian-led groups successfully lost weight while improving overall dietary adequacy. The group incorporating fortified meal replacements tended to have a more adequate essential nutrient intake compared to the group following a more traditional food group diet. This study supports the need to incorporate fortified foods and/or dietary supplements while following an energy-restricted diet for weight loss.With the current incidence of both overwe

Abstract: objective: to assess the extent of exposure for volatile organic compounds (vocs) among nonoccupationally exposed commuters in mexico city. material and methods: blood concentrations of benzene, toluene, ethylbenzene, m-/p-xylene, o-xylene and methyl tert-butyl ether were determined on samples collected from participants after the morning commute. results: median blood concentrations of benzene (0.11 mg/l), ethylbenzene (0.081 mg/l), m-/p-xylene (0.32 mg/l) and toluene (0.56 mg/l) in the mexico city participants were all approximately two times higher than in a nonsmoking subset of the third national health and nutrition examination survey population of the united states. on the other hand, median voc blood levels were similar to medians observed in other studies involving commuters in specific u.s. cities, despite the fact that only half the mexico city study participants commuted by personal vehicles compared with all u.s. commuters. conclusions: these results reflect the extent of the air pollution problem in mexico city. the surrounding topography exacerbates the problems caused by heavy vehicular traffic, poor emission-control devices on older vehicles, and poor maintenance practices. elevated levels of gasoline components in the blood of nonoccupationally exposed commuters emphasize the need for regulatory initiatives and mass-transit options to reduce hydrocarbon emissions and thus reduce the risk for nonoccupational exposure for the residents of mexico city.

BMC Family Practice , 2012, DOI: 10.1186/1471-2296-13-27
Abstract: Using a modified Delphi process including assessing perception of the frequency and criticality of performing tasks, we validated competencies important to primary health care pharmacists practising across Canada.Ten key informants contributed to competency drafting; thirty-three expert pharmacists replied to a second round survey. The final primary health care pharmacist competencies consisted of 34 elements and 153 sub-elements organized in seven CanMeds-based domains. Highest importance rankings were allocated to the domains of care provider and professional, followed by communicator and collaborator, with the lower importance rankings relatively equally distributed across the manager, advocate and scholar domains.Expert pharmacists working in primary health care estimated their most important responsibilities to be related to direct patient care. Competencies that underlie and are required for successful fulfillment of these patient care responsibilities, such as those related to communication, collaboration and professionalism were also highly ranked. These ranked competencies can be used to help pharmacists understand their potential roles in these evolving practices, to help other health care professionals learn about pharmacists' contributions to primary health care, to establish standards and performance indicators, and to prioritize supports and education to maximize effectiveness in this role.The increasing burden of chronic conditions on patients, their families and communities, and the health system, is leading the developed world to investigate new approaches to caring for patients. Primary health care, as the first level of contact with the health system for many individuals, has been refocused to emphasize health promotion, illness prevention and chronic disease management [1]. To address the challenge of access to primary health care, interprofessional models are emerging. Pharmacists are playing a growing part in primary health care reform by fulfi

Abstract: Purpose Working memory (WM) represents the brain’s ability to maintain information in a readily available state for short periods of time. This study examines the resting-state cortical activity patterns that are most associated with performance on a difficult working-memory task. Methods Magnetoencephalographic (MEG) band-passed (delta/theta (1–7 Hz), alpha (8–13 Hz), beta (14–30 Hz)) and sensor based regional power was collected in a population of adult men (18–28 yrs, n = 24) in both an eyes-closed and eyes-open resting state. The normalized power within each resting state condition as well as the normalized change in power between eyes closed and open (zECO) were correlated with performance on a WM task. The regional and band-limited measures that were most associated with performance were then combined using singular value decomposition (SVD) to determine the degree to which zECO power was associated with performance on the three-back verbal WM task. Results Changes in power from eyes closed to open revealed a significant decrease in power in all band-widths that was most pronounced in the posterior brain regions (delta/theta band). zECO right posterior frontal and parietal cortex delta/theta power were found to be inversely correlated with three-back working memory performance. The SVD evaluation of the most correlated zECO metrics then provided a singular measure that was highly correlated with three-back performance (r = ?0.73, p<0.0001). Conclusion Our results indicate that there is an association between WM performance and changes in resting-state power (right posterior frontal and parietal delta/theta power). Moreover, an SVD of the most associated zECO measures produces a composite resting-state metric of regional neural oscillatory power that has an improved association with WM performance. To our knowledge, this is the first investigation that has found that changes in resting state electromagnetic neural patterns are highly associated with verbal working memory performance.
Primary CNS T-Cell Lymphoma: A Case Report on a Solitary Cerebellar Lesion and Review of Current Relevant Literature  [PDF]
Aden McLaughlin, Sharon Gabizon
Open Journal of Modern Neurosurgery (OJMN) , 2013, DOI: 10.4236/ojmn.2013.32004

Primary central nervous system lymphoma of T-cell lineage (PCNSTL) is an extremely rare entity, with relatively few cases reported in the literature. Presented here is a case of a 44-year-old, HIV negative woman found to have a solitary cerebellar lesion following presentation to the Emergency Department with a fall. The lesion responded to emergent dexamethasone and was followed with serial MRI imaging, which continued to show lesion regression. The lesion was shown to have recurred on MRI 14 months post-presentation and found to be T-cell lymphoma following immunophenotyping and TCR gene rearrangement studies of tissue specimen obtained via excisional biopsy.

Rural nurses’ perceptions of a volunteer program in an acute setting: Volunteers delivering person-centred care for patients with dementia and delirium  [PDF]

Open Journal of Nursing (OJN) , 2014, DOI: 10.4236/ojn.2014.41005

Community volunteers were recruited and trained to deliver person-centred care to patients with dementia or delirium in an acute hospital setting, in a small rural Australian hospital. The volunteer program was grounded in action research methodology, and modelled on a previous research project. As a form of evaluation, interviews were conducted with nursing staff eight weeks after implementation of the volunteer program to explore their opinions. Data were analysed through a collaborative process and findings revealed strong benefits from the perspectives of the nursing staff. These benefits included overall improved patient care and improved time management for nursing tasks.

Farming Not Alone: Farmville Play and the Implications on Social Capital  [PDF]

Social Networking (SN) , 2014, DOI: 10.4236/sn.2014.35028
Abstract: This study explored the relationship between Farmville play and social capital. The implications of social game play for players’ psychological wellness were also assessed. Using survey data collected from Farmville players in Taiwan, it was found that the intensity of Farmville play was positively associated with players’ perceived bridging and bonding social capital. The extent to which intensive Farmville play may lead to the psychological benefits of enhanced life satisfaction and reduced loneliness was discussed. In addition, players who tended to add unacquaintances were more likely to perform better than those who added people they knew. However, connecting with existing contacts through the game provides higher sense of bonding social capital. Implications on the concept of weak and strong ties were also discussed.
Coupled IEEE 802.11ac and TCP Goodput Improvement Using Aggregation and Reverse Direction  [PDF]
Oran Sharon, Yaron Alpert
Wireless Sensor Network (WSN) , 2016, DOI: 10.4236/wsn.2016.87011
Abstract: This paper suggests a new model for the transmission of Transmission Control Protocol (TCP) traffic over IEEE 802.11 using the new features of IEEE 802.11ac. The paper examines the first step in this direction and as such we first consider a single TCP connection, which is typical in a home environment. We show that when the IEEE 802.11ac MAC is aware of QoS TCP traffic, using Reverse Direction improves the TCP Goodput in tens of percentages compared to the traditional contention based channel access. In an error-free channel this improvement is 20% while in an error-prone channel the improvement reaches 60% also using blind retransmission of frames. In our operation modes we also assume the use in Two-Level aggregation scheme, the Automatic Repeat-Request (ARQ) protocol of the IEEE 802.11ac MAC layer, the data rates and the four Access Categories defined in this standard.
A New Aggregation Based Scheduling Method for Rapidly Changing IEEE 802.11ac Wireless Channels  [PDF]
Oran Sharon, Yaron Alpert
Wireless Sensor Network (WSN) , 2016, DOI: 10.4236/wsn.2016.88013
Abstract: In this paper we suggest a novel idea to improve the Throughput of a rapidly changing WiFi channel by exploiting the standard aggregation schemes in IEEE 802.11ac networks. The idea is based on blindly transmitting several copies of the first 4 MAC Protocol Data Units (MPDU) in the Transmission Window. This increases the probability that the window moves forward, enabling the transmission of new MPDUs and resulting in increased Throughput. It turns out that transmitting 2 copies of each of the first 4 MPDUs yields the best Throughput gain, in the order of 50% - 60% in PHY rates of 1.3 - 3.5 Gbps and few hundreds of bytes MPDUs. The proposed idea has advantage over Link Adaptation since it reduces the actual PHY rate only for the transmission of few MPDUs while Link Adaptation reduces the PHY rate for all the transmissions.
