Association Between Body Iron Stores and Risk of Type 2 Diabetes in the Chinese Population: A Prospective Study
Creators: name: Liu, Zhaopei
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: AbstractionAims/hypothesisThe aim of this study was to examine the association between baseline body iron stores factors and incident type 2 diabetes mellitus. We hypothesized that elevated serum ferritin levels have a positive association with the incidence of type 2 diabetes, and soluble transferrin receptor levels and the ratio of soluble transferrin receptor to ferritin have negative associations with new-onset type 2 diabetes. Subjects and methodsA prospective cohort study explored associations between baseline iron stores factors and incident type 2 diabetes in 3198 adults who participated in both the waves of  2009 and 2015 China Health and Nutrition Survey. Three iron stores factors were categorized into quintiles, and the outcome measure was the incident cases of type 2 diabetes. ResultsThe mean baseline serum ferritin level for participants who developed type 2 diabetes during follow-up 6 years was significantly higher than those who did not have the disease. (169.4 ± 205.3 ng/mL vs 124.6 ± 170.0 ng/mL; P-difference<0.001). For multivariate logistic regression analysis, models were adjusted by known risk factors (age, gender, central obesity condition, blood pressure, smoking status, and physical activity); to minimize the effect of inflammation on iron stores factors, models were further adjusted by the inflammation factor (high-sensitivity CRP). After adjustment, the risk ratios (RRs) of incident type 2 diabetes across increasing quintiles of serum ferritin were 1.00, 1.51 (95% CI 0.85-2.67), 1.34 (95% CI 0.75-2.39), 1.70 (95% CI 0.96-3.00), 2.03 (95% CI 1.15-3.58) (P-trend=0.018); the RRs of incident type 2 diabetes across decreasing quintiles of the ratio of soluble transferrin receptor to ferritin were 1.00, 1.10 (95% 0.63-1.94), 1.12 (95% CI 0.64 1.97), 1.86 (95% CI 1.10-3.15), 1.51 (95% CI 0.93-2.78) (P-trend=0.049); there was not a significant association found between soluble transferrin receptor and new-onset type 2 diabetes. ConclusionElevated ferritin levels and a lower ratio of transferrin receptor to ferritin were independently associated with increased incident type 2 diabetes in Chinese populations.

description: It is shown that Vopěnka's Principle (VP) can restore almost the entire ZF over a weak fragment of it. Namely, if EST is the theory consisting of the axioms of Extensionality, Empty Set, Pairing, Union, Cartesian Product, $Δ_0$-Separation and Induction along $ω$, then ${\rm EST+VP}$ proves the axioms of Infinity, Replacement (thus also Separation) and Powerset. The result was motivated by previous results in \cite{Tz14}, as well as by H. Friedman's \cite{Fr05}, where a distinction is made among various forms of VP. As a corollary, ${\rm EST}+$Foundation$+{\rm VP}$=${\rm ZF+VP}$, and ${\rm EST}+$Foundation$+{\rm AC+VP}={\rm ZFC+VP}$. Also it is shown that the Foundation axiom is independent from ZF--\{Foundation\}+${\rm VP}$. It is open whether the Axiom of Choice is independent from ${\rm ZF+VP}$. A very weak form of choice follows from VP and some similar other forms of choice are introduced.

Neodymium isotope geochemistry of the southern Rocky Mountain volcanic field: connections between plutonic and volcanic rocks

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: New Nd isotopic data of zircon grains from dikes and spatially associated, penecontemporaneous tuffs within the Latir volcanic field (NM) and Mount Princeton (CO) do not show an isotopic connection between the dikes and tuffs. I hypothesize that these inconclusive results are from inheritance of Precambrian zircons within the samples. U-Pb geochronology data of the Questa ring dike sample supports this hypothesis because it is demonstrably older than previously dated samples. Future research should date the samples using zircon U-Pb geochronologic methods alongside the Nd analysis to ensure that the samples are not contaminated with inherited zircons.

description: A dynamical system is said to undergo rate-induced tipping when it fails to track its quasi-equilibrium state due to an above-critical-rate change of system parameters. We study a prototypical model for rate-induced tipping, the saddle-node normal form subject to time-varying equilibrium drift and noise. We find that both most commonly used early-warning indicators, increase in variance and increase in autocorrelation, occur not when the equilibrium drift is fastest but with a delay. We explain this delay by demonstrating that the most likely trajectory for tipping also crosses the tipping threshold with a delay and therefore the tipping itself is delayed. We find solutions of the variational problem determining the most likely tipping path using numerical continuation techniques. The result is a systematic study of the most likely tipping time in the plane of two parameters, distance from tipping threshold and noise intensity.

On Choice, Markets, and Care: An evaluation of the luck egalitarian treatment of unpaid care work
Creators: name: Nair, Gabrielle
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: In this paper, I explore how the luck egalitarian focus on choice and responsibility make it so that luck egalitarians cannot justly interpret the choice to do the unpaid labor that supports almost all families. In the first section of this paper, I discuss the problem choice presents for luck egalitarianism. Unpaid caregivers, usually women, face powerful norms that make it hard to draw the choice-luck line on which luck egalitarianism depends. In the second section, I explore the market-centric definitions of responsibility and prudence at the heart of luck egalitarianism that leave out unpaid caregivers. In the third section, I explain the inadequacy of amendments to luck egalitarianism that benefit unpaid caregivers. I conclude that luck egalitarianism is ill-equipped to handle the demands of the family. Instead, I argue that any comprehensive theory of justice must understand and accommodate the family as a major sociopolitical institution and have the ability to accommodate the needs of those who care for their families.

description: We report rotational periods for 16 young brown dwarfs in the nearby Upper Scorpius association, based on 72 days of high-cadence, high-precision photometry from the Kepler space telescope's K2 mission. The periods range from a few hours to two days (plus one outlier at 5 days), with a median just above one day, confirming that brown dwarfs, except at the very youngest ages, are fast rotators. Interestingly, four of the slowest rotators in our sample exhibit mid-infrared excess emission from disks; at least two also show signs of disk eclipses and accretion in the lightcurves. Comparing these new periods with those for two other young clusters and simple angular momentum evolution tracks, we find little or no rotational braking in brown dwarfs between 1-10 Myr, in contrast to low-mass stars. Our findings show that disk braking, while still at work, is inefficient in the substellar regime, thus provide an important constraint on the mass dependence of the braking mechanism.

Year: 2023

description: Background
 The sequential follow-up of the patient by the same medical professional at important stages of life or during the treatment of an illness is advantageous. The doctor-patient relationship is established with more confidence. It allows a holistic view of the individual's health. The academic training that includes sequential training in the progression of the disease, or different stages of an event, such as pregnancy, encourages the student to provide comprehensive and non-fragmented care for the individual.

 Summary Of Work
 For teaching in OBGyn, it was decided to create simulated stations that approach an event sequentially at different stages of evolution for the same patient. The idea was to assist in developing clinical reasoning and the lasting physician-patient relationship, strengthening the physician's role with comprehensive and continuous care. These sequential simulations of a patient's life story can help students acquire skills and attitudes at different moments of approach. This gives a global view of what is planned and expected when an event is observed.

 Summary Of Results
 Six sequential stations were elaborated addressing the consultation in gynecology and obstetrics. At the first station, with a woman who wants to get pregnant, the student performs the anamnesis, indicates exams, and provides guidance. In the second, the student receives and interprets the exams addressing family planning. Next, the pregnant patient returns to start prenatal care, and the student requests and evaluates exams, performs the physical exam, and provides guidance. At the fourth station, the student accompanies the patient in labor. On the fifth, the student participates in the delivery and provides immediate postpartum care. In the last one, he performs a postpartum consultation, recovering the patient's clinical history and planning future care.

 Discussion And Conclusion
 In this approach, the student understands the context of a phase of the patient's life from the moment of the desire for pregnancy and has the responsibility of planning the next steps in the seasons. Therefore, the perception that it is necessary to develop the doctor-patient relationship to establish a therapeutic bond, enables contextualized and integrated learning.

 Take Home Messages
 Imitating the sequence of events in simulated stations can broaden the student's view and facilitate clinical reasoning.
Development and adoption of transnational teaching strategies: a survey of learner and educator views and perceptions

description: Background

 Globalisation of society brings new opportunities and challenges in higher education(HE). Several UKbased universities now operate multiple campuses both in the UK and abroad. This presents
 opportunities to deliver teaching between two campuses and different countries, utilising the
 expertise in each campus. There has been limited research examining the views of learners and
 teachers on transnational teaching programmes. Our survey of student and staff opinions at one UK
 medical school with an international campus therefore aims to identify trends in learner and teacher
 views and conceptions of transnational education(TNE).

 Summary Of Work

 A cross-sectional study was distributed through the JISC online survey platform to both medical
 students and staff at the UK and NUMed medical school campuses. Following this, focus groups were
 held to gather quantitative data.

 Summary Of Results

 A total of 322 students and 35 staff responded to the questionnaire, of which 40 students and 10
 staff participated in the focus groups. Results show that students preferred interactive teaching
 formats (64%) over didactic formats (36%). The main barriers are the time zone difference between
 the UK and Malaysia (81%), and the incongruence between taught content and assessment
 outcomes (43%). 97% of students felt that TNE would improve their learning, while 82% believed that
 TNE would improve their assessment results.

 Discussion And Conclusion

 Data from qualitative interviews identified additional perceived benefits of virtual synchronous TNE.
 Students voiced that TNE improved teaching quality by utilizing local experts, optimizing the teaching
 workforce, and reducing discrepancies in curriculum delivery between the parent and satellite
 campus.

 Staff felt that TNE could build unique skill sets, such as graduates' cultural awareness,
 communication skills, work readiness, and global competitiveness. TNE provided valuable
 opportunities for professional development through establishing transnational working relationships,
 which encouraged teaching innovations, technological advancements, and research outputs.
 Students and staff suggested for TNE to be formally integrated into the curriculum, with structured
 and regular sessions addressing core education goals.

 Take Home Messages

 With HE TNE recognised as integral to the future development of UK education and global
 reputation, this research offers essential insights, and provides evidence for, the expansion of TNE.

Relations Among Maternal Distress, Bedtime Practices, and Infant Sleep Quality
Creators: name: Rowland, Sophia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Mothers with higher levels of depression and anxiety tend to report more sleep problems in their infants than mothers with lower levels of depression and anxiety. One mechanism by which maternal distress (i.e., depression and anxiety) could affect infant sleep outcomes is through the actions the mother performs as she readies her infant for nighttime sleep, referred to as maternal bedtime practices. Emerging literature links maternal distress with the practice of putting infants down for bed asleep, as well as greater amounts of close contact and directly arousing activities during the bedtime period. The interplay between maternal distress and bedtime practices has primarily been studied in Caucasian populations, even though African American children show worse sleep outcomes and are more likely to have mothers with depression. This study aims to examine the relationships between maternal distress (measured via self-report questionnaire), bedtime practices (coded from a video of the infant’s bedtime), and infant sleep outcomes (determined by actigraphy), in an African American population. Findings indicate that higher maternal distress at 3 months predicts a use of directly arousing activities at 3 months, and that putting the infant down to bed awake more often at 3 months predicts better sleep outcomes at 6 months. This study supports and extends the current literature by demonstrating that maternal distress and bedtime practices play a role in infant sleep quality in African American populations.
ORGANOMETALLIC CHEMISTRY FROM THE INTERACTING QUANTUM ATOM APPROACH
Creators: name: TIANA, DAVIDE
Publisher: name: Universit� degli Studi di Milano
Year: 2010

description: The Interacting Quantum Atoms approach(IQA) is a recent development of Bader?s QTAM(Quantum Theory of Atoms in Molecules). During the PhD studies the use of pseudopotential inside IQA was implemented allowing the study of transition metal compounds with this techniques. Furthermore IQA concepts were joined with Pon�c?s DAFH (Domain Avaraged Fermi Hole) giving the so-called IQA-EDF-DAFH analysis (EDF= electron-number distribution function) which provide a complete description of the chemical bond in terms of electron density. In order to make benchmark of this new technique classic metal-organic molecules like metal carbonyls, metal hydrides and simple metal dimeric compounds were studied.

description: Optical spectroscopic observations are reported for 24 and 23, nearby, proper-motion-selected M-dwarf candidate members of the Beta Pictoris and AB Doradus moving groups (BPMG and ABDMG). Using kinematic criteria, the presence of both Halpha emission and high X-ray-to-bolometric luminosity, and position in absolute colour-magnitude diagrams, 10 and 6 of these candidates are confirmed as likely members of the BPMG and ABDMG respectively. Equivalent widths or upper limits for the Li I 6708A line are reported and the lithium depletion boundary (LDB) age of the BPMG is revisited. Whilst non-magnetic evolutionary models still yield an estimated age of 21 +/- 4 Myr, models that incorporate magnetic inhibition of convection imply an older age of 24 +/- 4 Myr. A similar systematic increase would be inferred if the stars were 25 per cent covered by dark magnetic starspots. Since young, convective M-dwarfs are magnetically active and do have starspots, we suggest that the original LDB age estimate is a lower limit. The LDB age of the ABDMG is still poorly constrained -- non-magnetic evolutionary models suggest an age in the range 35-150 Myr, which could be significantly tightened by new measurements for existing candidate members.

description: Transfer learning is fundamental for addressing problems in settings with little training data. While several transfer learning approaches have been proposed in 3D, unfortunately, these solutions typically operate on an entire 3D object or even scene-level and thus, as we show, fail to generalize to new classes, such as deformable organic shapes. In addition, there is currently a lack of understanding of what makes pre-trained features transferable across significantly different 3D shape categories. In this paper, we make a step toward addressing these challenges. First, we analyze the link between feature locality and transferability in tasks involving deformable 3D objects, while also comparing different backbones and losses for local feature pre-training. We observe that with proper training, learned features can be useful in such tasks, but, crucially, only with an appropriate choice of the receptive field size. We then propose a differentiable method for optimizing the receptive field within 3D transfer learning. Jointly, this leads to the first learnable features that can successfully generalize to unseen classes of 3D shapes such as humans and animals. Our extensive experiments show that this approach leads to state-of-the-art results on several downstream tasks such as segmentation, shape correspondence, and classification.

We establish existence results and qualitative information about the solutions of these equations that also sheds light on the numerically observed behavior. In particular, we compute the topological index of the zeros of the single-reference Coupled-Cluster mapping. For the truncated Coupled-Cluster method, we derive an energy error bound for approximate eigenstates of the Schrodinger equation.

The Relationship between Parental Socioeconomic Status, Race, and Adolescent Suicidal Ideation
Creators: name: Murray, Kadejah S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: The suicide rate in the United States has increased by 24 percent since 1999. Both adolescent girls and boys experienced substantial suicide rate increases over this time period. Thus, there is very strong reason to understand the factors associated with adolescent suicidal thoughts (i.e., suicidal ideation) in the United States. This paper addresses the question whether household income is associated with adolescent suicidal ideation, and how this relationship is modified by race. Theoretically, Link and Phelan’s fundamental cause theory guides this research and suggests that suicidal ideation is associated with lower socioeconomic status. Data from Wave I of the National Longitudinal Study of Adolescent to Adult Health (Add Health), a nationally representative sample of 20,000 adolescents in the 7th through 12th grade during 1994-1995, were used to examine this relationship. Logistic regression analyses were utilized to test the influence of household income on adolescent suicidal ideation, controlling for age, race, gender, religious community, religious importance, parent’s educational attainment, and family structure. Results from this study show that there is no significant relationship between household income and adolescent suicidal ideation. Most importantly, however, this relationship is strongly modified by race. As household income increases, black adolescents have higher odds of suicidal ideation.  As household income increases for white adolescents, their odds of suicidal ideation are lower.  This research contributes to our understanding of which US adolescents are at highest risk for committing suicide and who should be the target of prevention campaigns.

description: A method for the reliable generation of random networks that model known social networks is becomingincreasingly desirable as a tool in the study of how these networks are structured and how they change overtime. This paper will present an algorithm capable of growing large directed networks that are designed tomodel a range of observed social networks with regard to several key measures. Our algorithm is looselybased on the Barabasi-Albert algorithm for scale-free graph generation. However, our model includes manyadditional parameters that play key roles in social networks, including a means of assigning attributes toindividuals in the network, which allows for the exploration of networks in which there is a certain degree ofdiversity. In doing so, we have produced an algorithm that is not only intuitive in its implementation, butalso extremely exible and easily adaptable to a variety of situations. Furthermore, the algorithm exhibitsstructural traits present in social networks but not produced by the Barabasi-Albert model. We will discussdirected and undirected versions of the algorithm, show how each version performs with regard to several keymetrics of the network, examine how the algorithm compares to observed real-world networks, and discussextensions of the model that could further enrich its modeling capabilities.

Agosti, one of the collectors of this species. Ptomaphaginus sinuatus Schilthuizen, 1984 Material.— Indonesia: Java: W Java, Mt. Gede, 50 km SE Bogor, 2000-2200 m, 5.xi.1989, leg. Agosti, Löbl, Burckhardt: 2 ♂♂, 3 ♀♀ (MHNG, CMPR). Remarks.— This species was only known from the holotype from Cigembong, SW Java, at 600 m altitude (Schilthuizen, 1984). These new specimens (which morphologically correspond closely with the holotype, with the exception that the habitus and aedeagus are somewhat less slender) derive from a locality in the vicinity, but at much greater altitude.

Gut microbiota in relation to glycemic status in rural & urban Chinese people
Creators: name: Kim, Yongkyum
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Although these phyla of bacteria, Firmicutes, Bacteroidetes, Proteobacteria, and
Actinobacteria have been studied with relation to diabetes, how microbiota vary in populations
experiencing rapid urbanization is now well studied. Transitioning from traditional rural to
Westernized urban lifestyles is associated with altered diet, decrease in physical activity, and
increased risk of diseases [19]. How the gut microbiota changes and how this affects disease risk
is still being explored. Increasing knowledge of how urbanization in China associates with
differences in the microbiome by contrasting urban and rural individuals living in similar regions
may be informative since previous studies have made such contrasts across different countries
and regions. The objective of this study is to examine how glycemic status is associated with
differences in the bacteria abundance in a similar region of southern China while thinking about
what role rural/urban status plays. Using linear regression, the Firmicutes, Bacteroidetes,
Proteobacteria, and Actinobacteria abundances in individuals with elevated versus normal
HbA1c was examined.

Novel Colorimetric Technique for the Detection of Pathogenic Vibrio vulnificus
Creators: name: Lorentz, Alexandra
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Vibrio vulnificus infections are expected to continue to increase with climate change yet current detection methods are either too expensive for wide spread use or unable to distinguish between strains likely to cause disease and those that will not. This study investigates the use of serum and mannitol to develop a culture-based detection method for pathogenic strains. Two genes correlated with virulence were used as indicators of pathogenicity, vcg and pilF. The medium developed contains 30% serum and 70% mannitol broth, and has accuracies in detecting pathogenic strains of V. vulnificus as high as 74% when pilF is used as the indicator of pathogenicity.

Rotating nuclei: from ground state to the extremes of spin and deformation
Creators: name: Afanasjev, A. V.
Publisher: name: arXiv

Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: The rotating nuclei represent one of most interesting subjects for theoretical and experimental studies. They open a new dimension of nuclear landscape, namely, spin direction. Contrary to the majority of nuclear systems, their properties sensitively depend on time-odd mean fields and currents in density functional theories. Moreover, they show a considerable interplay of collective and single-particle degrees of freedom. In this chapter, I discuss the basic features of the description of rotating nuclei in one-dimensional cranking approximation of covariant density functional theory. The successes of this approach to the description of rotating nuclei at low spin in pairing regime and at high spin in unpaired regime in wide range of deformations (from normal to hyperdeformation) are illustrated. I also discuss the recent progress and open questions in our understanding of the role of proton-neutron pairing in rotating nuclei at $N\approx Z$, the physics of band termination and other phenomena in rotating nuclei.

Determinants of exposure to household air pollution in rural Malawi
Creators: name: Kumar, Sangeetha
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: The very high exposure of people to airborne combustion products in developing
nations who use solid fuels (mainly wood) as the only source of fuel for cooking, often in
inefficient stoves and with poor ventilation is an important public health and
environmental issue. A research study done by UNC’s FUEL (Forest Use, Energy, and
Livelihoods) Lab collected data on determinants of exposure to household air pollution in
rural Malawi. The field study collected carbon monoxide (CO) and particulate matter
(PM2.5) for a period of 24 hours in each of the 108 households in the study. Additionally,
they collected both personal (the primary cooks of the household wore the monitors) and
area (placed in the primary cooking area) concentration measurements along with
completing an in-depth questionnaire with the household owners.
The goal of the study was to do a multivariate regression analysis of household
pollutant levels to see how different factors – the type of fuel, fuel quality, stove design,
ventilation conditions, etc. – influence indoor air pollutant exposures. The study found
that the interaction of ventilation, moisture content, stove type, income quintile, and
household size in a multivariate regression model best explains the variance of household
air pollutant concentrations. The identification of these determinants allows for further
studies on targeted interventions that reduce pollutant concentrations and adverse health
outcomes.
Separating conceptual priming from perceptual priming and stimulus-response learning

description: It is likely that both component processes and stimulus-response (S-R) learning contribute to priming and repetition suppression (RS). However, questions concerning S-R learning remain and we aim to distinguish the neural correlates of perceptual and conceptual components of priming, and S-R learning in the current investigation. The first purpose is to separate conceptual priming from perceptual priming and S-R learning. We will test if any region shows RS in a condition without perceptual overlap and without facilitation by S-R binding. Second, we will compare the amount of priming and RS in “orthogonal” approach with “changing referent” approach. We aim to answer whether two orthogonal conceptual tasks that access different semantic information can still cause conceptual priming and RS. Finally, we aim to replicate the findings that showed perceptual RS in the right fusiform gyrus (FG) and S-R learning in the right inferior frontal gyrus (IFG).
An Example of Banach and Hilbert manifold: the universal Teichmüller space

Publisher: name: arXiv

Subjects: subject: Mathematical Physics (math-ph)

description: For $s >\frac{3}{2}$, the group of Sobolev class s diffeomorphisms of the circle is a smooth manifold modeled on the space of Sobolev class s sections of the tangent bundle of the circle. It is a topological group in the sense that multiplication given by the composition of applications is well-defined and continuous, the inverse is continuous, left translation is continuous and right translation is smooth. These results are consequences of the Sobolev Lemma. For the same reasons, the subgroup of Sobolev class s diffeomorphisms of the circle preserving three points, is, for $s >\frac{3}{2}$ a smooth manifold and a topological group modeled on the space of Sobolev class s vector fields vanishing at these three points. One may ask what happens for the critical value $\frac{3}{2}$ and look for a group with some regularity and a manifold structure such that the tangent space at the identity is isomorphic to the space Sobolev class $\frac{3}{2}$ vector fields vanishing at three given points. The universal Teichmüller space verify these conditions.

description: Background: Globally, the increased use of cesarean sections has become prevalent in high-income and low and middle-income countries. In Palestine, the rate had risen from 20.3% in 2014 to 25.1% in 2018. We have rates as high as 35.8% in some governmental hospitals and some as low as 15%. This study aimed to understand better why there is a variation in cesarean rates in governmental hospitals that use the same guidelines.Methods: A qualitative and quantitative research approach was used. In-depth interviews were conducted with 27 specialists, obstetrics and gynecologists, and midwives in fve government hospitals. The hospitals were selected based on the 2017 Annual Health Report reported cesarean section rates. The interview guide was created with the support of specialists and researchers and was piloted. Questions focused mainly on adherence to the obstetric guidelines and barriers to the use, sources of information, training for healthcare providers, the hospital system, and the factors that afect decision-making. Each hospital’s delivery records for one month were analyzed to determine the reason for each cesarean section.Results: The results indicated that each governmental hospital at the system level had a diferent policy on cesarean sections. The National Guidelines were found to be interpreted diferently among hospitals. One obstetrician-gynecologist decided on a cesarean section at high-rate hospitals, while low-rate hospitals used collective decision-making with empowered midwives. At the professional level, all hospitals urged the importance of a continuous training program to refresh the medical team knowledge, in-house training of new members joining the hospital, and discussion of cases subjective to obstetrician-gynecologists interpretations.Conclusion: Several institutional factors were identifed to strengthen the implementation of the national obstetric guidelines. For example, encouraging collective decision-making between obstetrician-gynecologists and midwives, promoting the use of a second opinion, and mandatory training.
