Abstract:
Introduction: Data on hormonal intrauterine device (IUD) related adverse events in young women with inherited bleeding disorders (IBDs) are limited. Our primary objectives were to 1) examine adverse outcomes following IUD insertion in adolescents with heavy menstrual bleeding (HMB) and 2) compare IUD event-free survival in patients with and without IBDs. Methods: We performed a multi-center retrospective study of adolescents presenting to Young Women's Hematology Clinics at Nationwide Children's Hospital and Children's Medical Center, Dallas. All new patients with HMB at both clinics were enrolled in a HMB registry. We included registry participants who presented for evaluation of HMB between February 2014-February 2020 and had a levonorgestrel IUD placed. Electronic medical records were reviewed for clinical history, patient demographics, IBD diagnosis, IUD insertion, and post-IUD insertion follow up. We determined a priori IUD expulsion, removal due to malposition, or removal due to excessive pain or bleeding as clinically relevant adverse outcomes. Results: We identified 78 patients with IUD placement, of which 43 patients were diagnosed with IBDs. Of patients with IBD, the most common diagnoses were von Willebrand's disease/low von Willebrand factor (n=15), joint hypermobility syndrome/Ehlers-Danlos (n=15), and qualitative platelet disorder (n=9). The majority of patients were white (78%); 15% identified as Black. Nine percent of patients were Hispanic. Ninety percent of patients had failed at least one other method prior to IUD placement with the most common being combined estrogen/progestin oral contraceptive pills (79%), followed by progestin-only pills (37%), non-hormonal medications (DDAVP or anti-fibrinolytics) (26%), and depot medroxyprogesterone acetate (22%). Approximately half of the patients had an IUD inserted under general anesthesia (58%), with the remainder undergoing insertion in an outpatient clinic setting. Patients with IBDs were younger at time of IUD insertion (mean age 14 years, range 11-18) as compared to those without bleeding disorders (mean age 15 years, range 12-19, p=0.048). One-third (32%) of patients were sexually active prior to IUD insertion; this was not significantly different between groups. IUDs were found to be malpositioned or expelled on recheck in 21% of patients with IBD and 19% of patients without IBD (p=.87). Following IUD insertion, there was no significant difference in breakthrough bleeding that required treatment between the two groups, which occurred in 42% of patients with IBD and 26% in patients without IBD (p=.18). Patients with IBD were less likely than patients without IBD to request their IUD be removed prematurely (2% vs 20%, p<0.05). Overall, we found an annual rate of 0.25 adverse IUD events per 1 year of IUD insertion, with all adverse events occurring in the first 20 months after placement. Conclusions and future directions: While rates of expulsion and malposition were not higher in adolescents with IBD when compared to those without, they were higher than that of the general population (20% in our adolescent population with HMB vs 10% in the general population of nulliparous women <20 years of age, Madden et al, Obstetrics & Gynecology, 2015). Our study suggests that breakthrough menstrual bleeding after IUD insertion is equally likely in teens with HMB regardless of the diagnosis of IBD, with over a third of all patients requiring adjunctive therapy for breakthrough bleeding after IUD insertion. These findings highlight the need for appropriate counseling in this unique population as hormonal IUDs constitute an important treatment option for HMB in adolescents with and without IBD. Our work can inform shared decision making and patient counseling for the use of IUDs in young women with HMB and emphasizes the need for close follow-up after insertion to monitor for break through bleeding or malposition. Further research is needed to prospectively measure clinical outcomes and patient-reported outcomes after IUD insertion in young women with IBDs.

Abstract:
Objective: To implement a training protocol on intrauterine device (IUD) insertion for resident physicians to improve women’s access to this method. Methods: The staff identified poor access to family planning, in Vila Lobato health center, specially to IUD, there were only 15 IUD insertions in 2015. This implementation research evaluated and identified the barriers of access to IUD use. Then, stakeholders and staff defined the access flow of patients to the health unit and, eventually, the training provided to resident physicians in gynecology and obstetrics (GO) and family medicine (FM). This is a retrospective cohort of the IUD insertions performed by residents between 2016 and 2018. Results : 252 copper IUDs were inserted from 2016 to 2018 and there was a progressive increase in the number of insertions (45 in 2016, 80 in 2017, and 126 in 2018). Thirty-four (16.4%) inadequate insertions and 15 (8.6%) expulsions were observed. There was no case of uterine perforation. Conclusion: The implementation of the protocol on IUD insertion for residents in the primary care setting increased the local number of IUD insertion and might be a strategy to improve the access to the contraceptive method.

Abstract:
AimTo assess the incidence of visible strings of intrauterine contraceptive devices (IUDs) after postplacental insertion following vaginal or caesarean delivery and to establish a management protocol of follow-up visits when strings are not visualised.MethodsThis was a prospective study of a cohort of 348 women who underwent postplacental insertion of Copper-T 380A IUDs following vaginal or caesarean delivery, conducted at a hospital in New Delhi, India. Women were followed up at 6 weeks, 3, 6 and 12 months after IUD insertion and were questioned about IUD expulsion or removal at each visit. The cervix was inspected to visualise the IUD strings. All women whose IUD strings could not be visualised at the cervical os at any given follow-up were identified. We analysed the cumulative incidence of visible strings and of procedures performed to locate the IUD when strings were not visible.ResultsAt 1 year follow-up, the IUD wasin situin 313/348 (89.9%) women. There were eight (2.3%) expulsions and 15 (4.3%) IUD removals. Among women with IUDsin situ, the strings were not visible in 73 (21%) cases. Pelvic ultrasound confirmed intrauterine position of the IUDs in these cases. At 1 year, string visibility was significantly lower after intra-caesarean insertions as compared to vaginal insertions (72.4% vs 98.1%;p<0.05).ConclusionsVisualisation of strings after postplacental vaginal insertion is more common than after intra-caesarean insertion. Pelvic ultrasonography can be used to verify the presence of the device in cases of missing strings.

Abstract:
Background: Present study was carried out to compare the analgesic effect of oral diclofenac potassium versus hyoscine-N-butyl bromide (HBB) for pain relief during copper intrauterine device (IUD) insertion.Methods: It was a a randomized clinical trial carried out at Assiut University Hospital, Assiut, Egypt. Parous women eligible for Copper IUD insertion were recruited and randomized in a 1:1 ratio to diclofenac potassium or HBB. The participants were asked to take 2 tablets of the study medications 30 minutes before IUD insertion. The primary outcome was the participant's self-rated pain perception using a 10-cm Visual Analogue Scale (VAS) during IUD insertion. We considered a 1.5 cm difference in VAS scores between study groups as clinically significant.Results: One hundred eight women were enrolled (n=54 in each group). Diclofenac significantly has lower mean pain score during speculum placement (1.73 vs. 2.13) and tenaculum placement (1.85 vs. 2.3) than HBB with p<0.001. No statistical significant differences between both groups in other steps of IUD insertion. Additionally, the duration of IUD insertion was significantly lower in the diclofenac group (5.34±0.76 vs. 5.74±1.23 minutes, p=0.045). No women reported side effects in both groups.Conclusions: The use of oral diclofenac potassium 30 minutes prior to copper IUD insertion slightly reduce the insertional pain and duration than oral HBB with no adverse effects.

Objective: Systematic review and meta-analysis to assess the effects of uterine or paracervical lidocaine application on pain control during IUD insertion. Methods: PubMed and five other electronic research databases were searched through 15 November 2017 for RCTs comparing lidocaine treatment vs. a control (placebo or no-intervention) to prevent pain during IUD insertion. Searched terms included ‘IUD insertion’, ‘lidocaine’ and ‘randomised controlled trial’. RCTs evaluating lidocaine treatment before IUD insertion without restriction of language, age and IUD type. Pain measured by visual pain scales at tenaculum placement, IUD insertion and immediate post-IUD insertion. Results of random effects meta-analyses were reported as mean differences (MDs) of visual pain scale (VPS) scores and their 95% confidence intervals (CIs). Results: Eleven RCTs (n = 1458 women) reporting paracervical lidocaine block or uterine mucosa lidocaine application before IUD insertion. Lidocaine produced lower VPS scores during tenaculum placement (MD −0.99, 95% CI: −1.73 to −0.26), IUD insertion (MD −1.26, 95% CI: −2.23 to −0.29) and immediate post-IUD insertion period (MD −1.25, 95% CI: −2.17 to −0.33). Conclusion: Lidocaine treatment was associated with modest reduction of pain during tenaculum placement and after IUD insertion.

Abstract:
This thesis explores the behaviour of U(III) and U(IV) organometallic complexes towards small molecules, with respect to both their reductive activity and insertion chemistry. A range of mixed-sandwich U(IV) organyl complexes of the form U(η-C8H6{1,4-SiiPr3}2)(η-C5Me5)(R) (= U(COTTIPS2Cp*(R), where R = CH3, CH2Ph, CH2TMS, CH{TMS}2) have been synthesised and the products of their reactions with CO2, CO, and H2 (κ2-carboxylates, η2-acyls, and a monomeric terminal hydride) have been characterised – all of which are formed under mild conditions (< 1 atm of gas, sub-ambient temperature). The hydride also inserts CO2 to yield a formate, U(COTTIPS2)Cp*(κ2-O2CH), which is the first example of its kind, and inserts CO to form cis-enediolate, {U(COTTIPS2)Cp*}2(μ-κ1:κ1-OCH=CHO). A rare primary amido, U(COTTIPS2)Cp*(NH2), and its CO2 insertion product, U(COTTIPS2)Cp*(κ2-O2CNH2), have also been characterised. The latter is the first crystallographically characterised U(IV) primary carbamate. Deprotonation of the parent amido yield an anionic U(IV) terminal primary imido, [U(COTTIPS2)Cp*(NH)][K(18-crown-6)]. U(III) and U(IV) complexes containing a dianionic diamidoamine ligand, [N{SiMe3}(CH2CH2N{SiMe3})2]2- (= N'N'2) have been synthesised. It has been found that the migration of a SiMe3 group along the ligand backbone occurs spontaneously when bound to uranium. Reduction of the U(IV) compound U(N'N'2)Cp*Cl with KC8 yields either the U(III) product, U(N'N'2)Cp*, or bridging arene products, {U(N'N'2)}2(μ-η6:η6-C6H5R) (where R = H, Me), depending on the reaction stoichiometry. Further reactivity of these diamidoamine complexes with small molecules is also discussed.

Abstract:
Alkylidene carbenes are reactive intermediates in organic chemistry. Intramolecular 1,5 C-H insertion reactions lead to cyclopentenes with retention of configuration. Insertions into O-Si or O-H bonds form dihydrofurans. Chapter 1 reviews of the chemistry of alkylidene carbenes, focusing on their reactivity and the techniques that can be employed for their in situ generation. Factors governing the selectivity of these reactive intermediates are discussed. Previous investigations in the Grainger group on the use of alkylidene carbenes in model studies towards the synthesis of the cyclopentene A-ring of ingenol, a biologically active diterpene, are described. Chapter 2 describes an investigation into hydroxycyclopentene annulation using the 1,5 C-H insertion reaction of α-hydroxyalkylidene carbenes on a 2,4-dimethyl-substituted 8-oxabicyclic ring system. Syntheses of α,β-epoxy-N-aziridinylimines, known precursors to α-hydroxyalkylidene carbenes, are achieved in 5-6 steps through initial stereoselective addition of a vinyl lithium species to 2,4-dimethyl-8-oxabicyclo[3.2.1]oct-6-en-3-one. The diastereoselectivity (diastereotopic group selectivity) of the alkylidene carbene insertion reaction is reversed upon protection of a tertiary alcohol at C-3 of the oxabicylic ring system as a trimethylsilyl ether. Application of the hydroxycyclopentene annulation on an 8-oxabicyclic ring system bearing a benzyloxy substituent on the 2-position is described in chapter 3. Selective insertion adjacent to the benzyloxy group is observed irrespective of the tertiary alcohol substituent at C-3. Competing O-H and O-Si insertion, fragmentation and 1,2-rerrangement occur to a much greater extent than for the 2,4-dimethyl system. Chapter 4 compares the selectivity of alkylidene carbenes generated in the dimethyl and benzyloxy-substituted oxabicyclic ring systems. Alkylidene carbenes lacking the α-hydroxy group, generated via either the deprotonation of vinyl chlorides, or the reaction of ketones with lithio(trimethylsilyl)diazomethane, show similar reactivity differences in the 3-trimethylsilyloxyoxabicyclic systems as those bearing the α-hydroxyl group. The ratio of C-H insertion to O-Si insertion depends on the method of generation employed.

Abstract:
The area of focus for this research is the Stochastic Resource Constrained Project Scheduling Problem (SRCPSP) with Stochastic Task Insertion (STI). The STI problem is a specific form of the SRCPSP, which may be considered to be a cross between two types of problems in the general form: the Stochastic Project Scheduling Problem, and the Resource Constrained Project Scheduling Problem. The stochastic nature of this problem is in the occurrence/non-occurrence of tasks with deterministic duration. Researchers Selim (2002) and Grey (2007) laid the groundwork for the research on this problem. Selim (2002) developed a set of robustness metrics and used these to evaluate two initial baseline (predictive) scheduling techniques, optimistic (0% buffer) and pessimistic (100% buffer), where none or all of the stochastic tasks were scheduled, respectively. Grey (2007) expanded the research by developing a new partial buffering strategy for the initial baseline predictive schedule for this problem and found the partial buffering strategy to be superior to Selim s extreme buffering approach. The current research continues this work by focusing on resource aspects of the problem, new buffering approaches, and a new rescheduling method. If resource usage is important to project managers, then a set of metrics that describes changes to the resource flow would be important to measure between the initial baseline predictive schedule and the final as-run schedule. Two new sets of resource metrics were constructed regarding resource utilization and resource flow. Using these new metrics, as well as the Selim/Grey metrics, a new buffering approach was developed that used resource information to size the buffers. The resource-sized buffers did not show to have significant improvement over Grey s 50% buffer used as a benchmark. The new resource metrics were used to validate that the 50% buffering strategy is superior to the 0% or 100% buffering by Selim. Recognizing that partial buffers appear to be the most promising initial baseline development approach for STI problems, and understanding that experienced project managers may be able to predict stochastic probabilities based on prior projects, the next phase of the research developed a new set of buffering strategies where buffers are inserted that are proportional to the probability of occurrence. The results of this proportional buffering strategy were very positive, with the majority of the metrics (both robustness and resource), except for stability metrics, improved by using the proportional buffer. Finally, it was recognized that all research thus far for the SRCPSP with STI focused solely on the development of predictive schedules. Therefore, the final phase of this research developed a new reactive strategy that tested three different rescheduling points during schedule eventuation when a complete rescheduling of the latter portion of the schedule would occur. The results of this new reactive technique indicate that rescheduling improves the schedule performance in only a few metrics under very specific network characteristics (those networks with the least restrictive parameters). This research was conducted with extensive use of Base SAS v9.2 combined with SAS/OR procedures to solve project networks, solve resource flow problems, and implement reactive scheduling heuristics. Additionally, Base SAS code was paired with Visual Basic for Applications in Excel 2003 to implement an automated Gantt chart generator that provided visual inspection for validation of the repair heuristics. The results of this research when combined with the results of Selim and Grey provide strong guidance for project managers regarding how to develop baseline predictive schedules and how to reschedule the project as stochastic tasks (e.g. unplanned work) do or do not occur. Specifically, the results and recommendations are provided in a summary tabular format that describes the recommended initial baseline development approach if a project manager has a good idea of the level and location of the stochasticity for the network, highlights two cases where rescheduling during schedule eventuation may be beneficial, and shows when buffering proportional to the probability of occurrence is recommended, or not recommended, or the cases where the evidence is inconclusive.

Abstract:
Escherichia coli is one of the most studied model organisms in biology. Even with decades of research, there are a substantial number of genes with an as yet unknown function. Previously, to determine the link between gene function and phenotype took significant experimental effort. However, newer methods are capable of providing large amounts of biological data in short timeframes. One such method, transposon insertion sequencing, is a powerful research tool, which couples transposon mutagenesis and next generation sequencing to identify genes that have important or essential functions. Here, three transposon insertion sequencing methods were compared. The techniques were adapted from previously published literature. Based on a number of metrics one technique was shown to be superior for data generation. This method was chosen for application in further transposon-insertion sequencing experiments. Subsequently, the optimised method was used to assess which genes were essential for the viability of the model organism E. coli K12. The results of this work were compared with the literature and other databases of gene essentiality. A high degree of concordance was observed between our datasets and those generated previously through other methods. Indeed, the method described here was shown to have several benefits over previously used approaches. Finally, genes involved with maintenance of the outer membrane were identified by using markers for membrane permeability in tandem with the chosen method. In keeping with previous literature multiple genes involved with many aspects of the cell envelope were reported. Many of the reported genes were shown to be involved with metabolic processes related to the biogenesis and maintenance of the cell envelope.

Abstract:

In this thesis it was argued that the prime reason of the Deuteronomistic Historian (Dtr) for inserting the incomparability of God in Solomon's prayer was to convey his (Dtr's) theological interpretation of the history of Israel as history controlled by her sovereign God, Yahweh. Other reasons were also considered. This study does not pusue the incomparability formula throughout the Deuteronomistic writings, but confined itself to the prayer of Solomon and more specifically to the use of the incomparability formula. Therefore, this study intended to examine, in a scholarly and responsible manner, the main reason(s) for the insertion of the statement of the incomparability of God in king Solomon's prayer.

Bone-to-implant contact of orthodontic mini-screws has been determined via Micro-CT to be a strong predictor of primary stability. Various insertion angulations, including both 900 and 500, have been reported as ideal for providing optimum primary stability. The aim of this investigation was to determine if a statistically significant difference exists in the bone-to-implant contact of mini-screws placed with an insertion angulation of 900 compared to those placed at 500 as determined via Micro-CT. Ten self-drilling, self-tapping orthodontic mini-screws (Aarhus,1.5mmx6mm) (n=5) were inserted into the posterior ramus of an adult pig mandible, an analog to an adult human mandible. A custom stent with ten holes, five at 900 and five at 500, was fitted to the bone surface to control insertion angulation. The bone was cut to 1.5x1.5x1cm segments and scanned using SkyScan 1127 with ideal specifications (8mm pixel size, medium camera, 80Kv, 100mA, 10W, 1800 rotation, and 0.5Al+0.25Cu filter). The raw scans were reconstructed using NReconV1.6.10 and these datasets were then reoriented using DataviewerV1.5.2 along the Z-axis to standardize the peri-implant bone for analysis. A custom task-list was used with CT-AnalyzerV1.14.41 to determine the percent of bone-to-implant contact per mini-screw. A Mann-Whitney U test indicated that the bone-to-implant contact was not statistically significantly different for the mini-screws placed at 900 (Mdn= 72.34) compared to the mini-screws placed at 500 (Mdn= 53.25), U=5, p=.1443. Therefore, the results do not significantly differ at p<.05. There is no statistically significant difference in the bone-to-implant contact between the Aarhus 1.5mmx6mm orthodontic mini-screws placed at 900 compared to those placed at 500 as measured by Micro-CT. This may lead to the conclusion that there is no significant difference in the primary stability of Aarhus mini-screws placed at 900 and 500.

Abstract:
Project managers are faced with the challenging task of managing an environment filled with uncertainties that may lead to multiple disruptions during project execution. In particular, they are frequently confronted with planning for routine and non-routine unplanned work: known, identified, tasks that may or may not occur depending upon various, often unpredictable, factors. This problem is known as the stochastic task insertion problem, where tasks of deterministic duration occur stochastically. Traditionally, project managers may include an extra margin within deterministic task times or an extra time buffer may be allotted at the end of the project schedule to protect the final project completion milestone. Little scientific guidance is available to better integrate buffers strategically into the project schedule. Motivated by the Critical Chain and Buffer Management approach of Goldratt, this research identifies, defines, and demonstrates new buffer sizing techniques to improve project duration and stability metrics associated with the stochastic resource constrained project scheduling problem with stochastic task insertions. Specifically, this research defines and compares partial buffer sizing strategies for projects with varying levels of resource and network complexity factors as well as the level and location of the stochastically occurring tasks. Several project metrics may be impacted by the stochastic occurrence or non-occurrence of a task such as the project makespan and the project stability. New duration and stability metrics are developed in this research and are used to evaluate the effectiveness of the proposed buffer sizing techniques. These "robustness measures" are computed through the comparison of the characteristics of the initial schedule (termed the infeasible base schedule), a modified base schedule (or as-run schedule) and an optimized version of the base schedule (or perfect knowledge schedule). Seven new buffer sizing techniques are introduced in this research. Three are based on a fixed percentage of task duration and the remaining four provide variable buffer sizes based upon the location of the stochastic task in the schedule and knowledge of the task stochasticity characteristic. Experimental analysis shows that partial buffering produces improvements in the project stability and duration metrics when compared to other baseline scheduling approaches. Three of the new partial buffering techniques produced improvements in project metrics. One of these partial buffers was based on a fixed percentage of task duration and the other two used a variable buffer size based on knowledge of the location of the task in the project network. This research provides project schedulers with new partial buffering techniques and recommendations for the type of partial buffering technique that should be utilized when project duration and stability performance improvements are desired. When a project scheduler can identify potential unplanned work and where it might occur, the use of these partial buffer techniques will yield a better estimated makespan. Furthermore, it will result in less disruption to the planned schedule and minimize the amount of time that specific tasks will have to move to accommodate the unplanned tasks.

Abstract:
This chapter discusses device therapy in ACHD. Insertion of devices in these patients requires special consideration. Knowledge of underlying anatomy, previous surgical procedures, and vascular access routes; an understanding of problems likely to be encountered with lead placement in complex hearts; and obtaining a stable position are all crucial. This chapter discusses bradycardia pacing, implantable cardiac defibrillators (ICD), cardiac resynchronization therapy (CRT), and technical considerations for device therapy in ACHD.
