Published: August 2016

AbstractBackground:Erythropoietin seems to play an important role in the regulation of fetal hypoxemia. The present prospective study was designed to determine if changes in erythropoietin levels can be found in fetuses with severe early-onset growth restriction and hemodynamic compromise.Methods and results:Erythropoietin, hemoglobin, hematocrit, platelet counts, normoblasts, lacate, arterial and venous blood gasses in the umbilical cord were determined in 42 fetuses with fetal growth restriction (IUGR) with absent (zero-flow) and 26 IUGR fetuses with retrograde end-diastolic flow (reverse-flow) in the umbilical artery. Color Doppler measurements were performed on the middle cerebral artery (PI) and ductus venosus [(S-a)/D and (S-a)/VConclusions:Fetuses with severe IUGR due to chronic placental insufficiency and absent or reversed flow in the umbilical artery show increased erythropoietin levels.

Zusammenfassung:
Die Befragung von sozial benachteiligten Personen stellt häufig eine Herausforderung dar. In dieser Studie wurde die Möglichkeit einer Befragung von Tafelkunden vor Ort genutzt. Tafeln sammeln Lebensmittel und geben sie an Bedürftige weiter. Die Ergebnisse zeigen, dass Tafelkunden einen ähnlichen Obst- und Gemüsekonsum wie der Bundesdurchschnitt aufweisen. Im direkten Vergleich mit Daten von sozial benachteiligten Personen, die keine Tafeln in Anspruch nehmen, hat sich ein höherer Verzehr von Obst und Gemüse bei Tafelkunden gezeigt. Übergewicht und Adipositas scheint unter Tafelkunden dennoch stark verbreitet zu sein.

Published: August 2016

BACKGROUND:Pediatricians are central in leading the family-centered medical home (FCMH), yet little is known about how provider-perceived barriers to and attitudes toward the FCMH affect implementation. This study aims to assess the relationship between pediatrician-perceived barriers to and attitudes toward FCMH and reported care coordination.METHODS:Pediatricians working in ambulatory care responded to the American Academy of Pediatrics Periodic Survey of Fellows #79 (N = 572, response rate, 59%). Our primary care coordination outcomes were whether pediatricians were: (1) leading a multidisciplinary team; (2) developing care plans; and (3) connecting with support services. Independent variables included barriers to FCMH implementation (lack of communication skills, support services, and time). Associations between outcomes and barriers were assessed by multivariate logistic regression, controlling for pediatrician and practice characteristics.RESULTS:Lack of sufficient personnel was significantly associated with fewer care coordination activities: leading a multidisciplinary team (odds ratio [OR], 0.53), developing care plans (OR, 0.51), and connecting with support services (OR, 0.42). Lacking communication skills was significantly associated with lower odds of development of care plans (OR, 0.56) and assistance with support services (OR, 0.64). Lack of time was significantly associated with lower odds of leading a multidisciplinary team (OR, 0.53). A pediatrician’s belief that the FCMH encourages the use of preventive services was significantly associated with increased support services (OR, 2.06).CONCLUSIONS:Pediatricians report a need for sufficient personnel and communication skills to provide care coordination, a core component of the FCMH. Interventions to boost FCMH implementation should focus on providing resources to develop these characteristics.

Published: August 2016

AbstractOptical properties and thermal properties of self-polarized thin PZT films were determined by variable angle spectral ellipsometry and by the AC hot strip method, respectively. Analyzing the temperature dependencies of the optical gap and the specific heat, evidence of two not as yet observed phase transitions in the ferroelectric was provided. The origin of these phase transitions was attributed to film stress caused by substrate/PZT thin film lattice mismatch and to the presence of a negative space charge layer in the PZT film at the bottom electrode/PZT interface.

Shale Industry Needs to Look Within for Solutions That Save
Authors: Jacobs Trent 
Published: August 2016

Conference review - 2015 Unconventional Resources Technology Conference
July’s drop in oil prices to below USD 50/bbl reminded the shale industry that the hard times may be around for a while and that operators need to continue working on their cost reduction plans. At the recent 2015 Unconventional Resources Technology Conference, a major theme was how companies can improve performance without increasing the size of their budget.
Some companies are looking to work closer with other companies to share knowledge and technology that may yield higher production. Others are looking inward for ideas that may reduce risk and improve the bottom line.
Barry Biggs, vice president of onshore operations at Hess, described the lean approach that the company has adopted, which includes using “an army of problem solvers.” Counter to their moniker, this cadre of key employees are not exclusively working on problems. He said that too often, operators are focused more on finding out what went wrong in an operation rather than what went right.
“Well, flip that. What is the root cause analysis of things you are doing well?” he asked. “It is a mental shift that we can use to try to drive improvement.”
He credited this business structure with helping Hess drive down costs by 50% in the Bakken Shale from 2012 to 2015. Biggs said it has also been critical in allowing the company to develop the Utica Shale faster than the Bakken despite the geologic differences of the two plays.
Instead of dictating orders from the top down, this leadership style asks questions, welcomes debate, and relies on collaboration while still holding people accountable for meeting their goals, Biggs said.
One example of its management strategy is written on the walls of the company’s asset collaboration rooms, where team leaders post their business plans and status reports for all to see. Once a week, engineers and executives go around the room trying to solve whatever problems that are being encountered. Biggs said this visual approach of project management “is much more powerful than a report that gets circulated around.”
While operators trim their own fat, a hefty portion of the savings they are seeing today are a result of the pressure on service companies to lower their prices, in many cases by about 30% or more. “However, we can’t get to where we need to be with cost reductions alone,” said Peter Richter, vice president of unconventional resources at Schlumberger. “These cost reductions, while they are nice for the immediate economics, they are not sustainable for the long term.”
To emerge from the downturn stronger than before it entered in, Richter said the unconventional sector needs to adopt an align-and-conquer strategy. By integrating data and collaborating more on drilling and completion operations, both efficiency and production can be improved, he said.
Limiter Redesign Process Expands To Cover Flat-Time Operations

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper SPE 170751, “Maximizing Capital Efficiency by Expanding the Limiter Redesign Process to Flat-Time Operations,” by M.A. Valenta, SPE, M.W. Walker, SPE, P.E. Pastusek, SPE, J.R. Bailey, SPE, W.C. Elks, SPE, S.B. Lewis, SPE, and N.D. Mitchell, ExxonMobil Development Company, prepared for the 2014 SPE Annual Technical Conference and Exhibition, Amsterdam, 27–29 October. The paper has not been peer reviewed.
The Fast Drill Process has become a well-known work flow to identify hole-making limiters and mitigate them through redesign to the economic limit of performance. To address operations that do not include drilling of rock, the operator launched a similar effort and work flow that focus on flattime portions of well construction. This process is yielding significant savings globally and has been accomplished through planning, realtime recognition and response, and collaboration while improving safety performance continuously.
Evolution of the Fast Drill Process
In 2004, the operator started a pilot program to determine if drilling performance could be improved by analyzing and reacting to trends in mechanical specific energy (MSE). MSE is a performance measurement parameter that approximates the bit’s drilling efficiency and is a function of weight on bit (WOB), surface torque, bit rotation per revolution, and rate of penetration (ROP) for a given hole size. Results of a pilot program confirmed that significant ROP performance gains could be obtained simply by monitoring MSE trends and adjusting the drilling parameters (WOB and bit rotation per revolution) at the rigsite to minimize MSE. This process was deployed in 2005 and is known as the Fast Drill Process.
The operator refined the work flow to improve drill rate performance. The work flow follows a plan/do/analyze/improve cycle to identify and overcome limiters in the drilling operation. The key elements of the Limiter Redesign Process are
Identify the current limiter.
Plan to extend the limiter.
Identify risks with change.
Plan to mitigate risks.
Run trial and take data.
Adjust trial on the basis of real-time events.
Capture learnings.
Repeat the cycle to the economic limit.
Internally the Limiter Redesign Process was renamed Fast Drill Borehole Management (FDBM). The new expanded objective was to improve borehole quality and address near-misses in the upfront drilling-design process and in real-time drilling operations. The FDBM initiative was the continued evolution of the Fast Drill Process.
Effectiveness of the transpalatal arch in controlling orthodontic anchorage in maxillary premolar extraction cases: A systematic review and meta-analysis

Published: August 2016

ABSTRACT
Objective: To evaluate the effectiveness of the transpalatal arch (TPA) as an anchorage device in preventing maxillary molar mesialization during retraction of the anterior teeth after premolar extraction.
Materials and Methods: This systematic review intended to include patients indicated for upper premolar bilateral extraction and subsequent retraction of anterior teeth, considering the use of TPA as an anchorage tool in one of the treatment groups. The search was systematically performed, up to April 2015, in the following electronic databases: Medline, Embase, and all evidence-based medicine reviews via OVID, Cochrane Library, Scopus, PubMed, and Web of Science. Risk of bias assessment was performed using Cochrane's Risk of Bias Tool for randomized clinical trials (RCTs) and Methodological Index for Nonrandomized Studies (MINORS) for non-RCTs.
Results: Fourteen articles were finally included. Nine RCTs and five non-RCTs presented moderate to high risk of bias. Only one study investigated the use of TPA in comparison with no anchorage, failing to show significant differences regarding molar anchorage loss. A meta-analysis showed a significant increase in anchorage control when temporary anchorage devices were compared with TPA (mean difference [MD] 2.09 [95% confidence interval {CI} 1.80 to 2.38], seven trials), TPA + headgear (MD 1.71 [95% CI 0.81 to 2.6], four trials), and TPA + utility arch (MD 0.63 [95% CI 0.12 to 1.15], 3 trials).
Conclusion: Based on mostly moderate risk of bias and with some certainty level, TPA alone should not be recommended to provide maximum anchorage during retraction of anterior teeth in extraction cases.

Published: August 2016

OBJECTIVE
This study tests the effectiveness of expert guidelines for diabetes prevention: lifestyle intervention with addition of metformin, when required, among people with prediabetes.

RESEARCH DESIGN AND METHODS
The Diabetes Community Lifestyle Improvement Program (D-CLIP) is a randomized, controlled, translation trial of 578 overweight/obese Asian Indian adults with isolated impaired glucose tolerance (iIGT), isolated impaired fasting glucose (iIFG), or IFG+IGT in Chennai, India. Eligible individuals were identified through community-based recruitment and randomized to standard lifestyle advice (control) or a 6-month, culturally tailored, U.S. Diabetes Prevention Program–based lifestyle curriculum plus stepwise addition of metformin (500 mg, twice daily) for participants at highest risk of conversion to diabetes at ≥4 months of follow-up. The primary outcome, diabetes incidence, was assessed biannually and compared across study arms using an intention-to-treat analysis.

RESULTS
During 3 years of follow-up, 34.9% of control and 25.7% of intervention participants developed diabetes (P = 0.014); the relative risk reduction (RRR) was 32% (95% CI 7–50), and the number needed to treat to prevent one case of diabetes was 9.8. The RRR varied by prediabetes type (IFG+IGT, 36%; iIGT, 31%; iIFG, 12%; P = 0.77) and was stronger in participants 50 years or older, male, or obese. Most participants (72.0%) required metformin in addition to lifestyle, although there was variability by prediabetes type (iIFG, 76.5%; IFG+IGT, 83.0%; iIGT, 51.3%).

CONCLUSIONS
Stepwise diabetes prevention in people with prediabetes can effectively reduce diabetes incidence by a third in community settings; however, people with iIFG may require different interventions.
Food aversion learning in sheep: persistence of conditioned taste aversions to palatable shrubs (Cercocarpus montanus and Amelanchier alnifolia)
Authors: Burritt E. A. , Provenza F. D. 
Published: August 2016

Abstract
We studied the persistence of conditioned taste aversions in sheep and whether or not sheep averted to one shrub species would avoid another shrub species. Three-month-old lambs were averted to the shrub Cercocarpus montanus by pairing its ingestion with lithium chloride (LiCl), a nonlethal gastrointestinal poison. When lambs were yearlings, they were offered C. montanus plants growing in 8-liter pots. During the persistence trial, averted sheep took fewer (P < .05) bites of C. montanus than controls did (19 vs 64 bites/sheep, respectively). Following the persistence trial, sheep that had been previously averted to C. montanus and consumed C. montanus received LiCl. Complete aversion to C. montanus was re-established in previously averted sheep with a single dose of LiCl. When sheep previously averted to C. montanus were offered potted Amelanchier alnifolia shrubs, averted sheep consumed 21 bites of A. alnifolia but controls consumed 58 bites (P < .05). This result suggests that previously averted sheep were either more food neophobic than controls or generalized their aversion from C. montanus to A. alnifolia. As with C. montanus, a single dose of LiCl completely averted sheep to A. alnifolia. When sheep grazed a pasture containing C. montanus and A. alnifolia averted sheep took fewer (P < .05) bites of the two shrubs than controls did (.2% vs 18%). Sheep showed no signs of extinguishing the aversion to either shrub during the grazing season (May-Sept.). Aversive conditioning may be useful to manipulate diet selection of free-ranging livestock.

Abstract
Carcasses and(or) tissues of 510 boars and 510 barrows were analyzed for lean content, muscle quality, incidence of objectionable odor, 5α-androstenone concentration and skatole concentration. Boars and barrows differed (P < .01) in warm carcass weight (73.5 vs 80.1 kg), longissimus muscle area (36. vs 35. cm2), 10th rib fat depth (1.80 vs 2.57 cm), estimated percent muscle (56.1 vs 51.3%) and marbling score (1.73 vs 1.97). No difference (P > .05) was found for muscle color score (2.51 vs 2.45). Although odor panel scores were higher (P < .01) for boars than for barrows (1.74 vs 1.56), both scored quite low. The correlation coefficients between panel scores and 5α-androstenone content (.13) and between panel scores and skatole content (−.14) were nonsignificant (P > .05). These results indicate that boars reared in U.S. commercial production facilities produce lean meat more efficiently than barrows do and they have a low incidence of offensive odor. Concentration of 5α-androstenone and skatole in backfat proved unrelated to odor intensity.

Published: August 2016

Abstract
This study was designed to evaluate profiles of serum concentrations of LH, pituitary content of LH and GnRH receptors, and hypothalamic content of GnRH in undernourished, ovariectomized ewes. In earlier studies, pulsatile secretion of LH diminished as duration of undernutrition progressed in prepubertal or adult ovariectomized ewes. Ewes having similar body condition scores (CS) of 5 to 9 (1 = extremely thin, 5 = moderate, 9 = obese) were fed maintenance or low-energy diets (100% and 60% of NRC requirements, respectively). Blood samples for analysis of LH were collected at 15-min intervals for 4 h at initiation of the project and immediately prior to slaughter. Serum concentrations of LH did not differ (P > .05) among groups at the initial sampling period. At slaughter, ewes with CS ≤ 2 (n = 7) had lost 26.8 kg (42% of initial weight). Ewes with CS ≥ 3 (n = 12) had lost an average of 13.7 kg (18% of initial weight). Concentrations of LH in ewes with final CS ≥ 3 was similar (P > .05) to that observed during the initial sampling period. However, release of LH was reduced (P < .01) in ewes with CS ≤ 2 compared with ewes with CS ≥ 3 (2.6 vs 9.5 and 3.2 vs 10.5 ng/ml for basal and mean concentrations, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)
Adipose tissue development in the fetal pig examined using monoclonal antibodies.
Authors: Wright J. T. , Hausman G. J. 
Published: August 2016

Abstract
Two anti-adipocyte monoclonal antibodies (MAbs; AD-1 and AD-2) have been used to study the development of dorsal s.c. adipose tissue in fetuses from 50 to 110 d of gestation. Immunofluorescent staining of cryostat sections with each antibody revealed antigen-positive cells in fetal s.c. mesenchyme prior to lipid deposition. Lipid droplets as well as AD-1 and AD-2 positive cells were detected within the underlying muscle at 50 d. From 70 to 110 d of development, the AD-1 and AD-2 MAbs each detected all adipocytes examined, as well as capillaries associated with fat cell clusters in s.c. tissues. Reactivity toward both antibodies, as well as lipid deposition, also was detectable in the muscle underlying the s.c. mesenchyme from 70 d onward. Each MAb possessed a distinct pattern of reactivity. The AD-2 MAb stained arrector pili muscles and vessels in the s.c. mesenchyme and vessels in the underlying muscles, whereas the AD-1 did not. No reactivity using either MAb was detectable toward any other cell types within s.c. tissues. These results established the presence of cells expressing surface determinants found on mature adipocytes and associated capillaries prior to adipogenesis. A lineage relationship between adipocytes and capillary endothelial cells is suggested.
