1	Women's experiences of amenorrhea following Depo-Provera use at a district hospital in Malawi Mwafulirwa, Boss January 2016 (has links) Magister Curationis - MCur / Depo-Provera, an injectable contraceptive, is utilized by about 30% of married women in Malawi. Most women have reported their preference to use Depo-Provera due to its effectiveness in preventing pregnancy, reversibility and easy to use since it is given once at 12-weeks intervals. Despite the method having such advantages, it has menstrual effects, and one of the major concerns for women, particularly in Africa, is amenorrhea. In Malawi, 40% of Depo-Provera users report experiencing amenorrhea after one year of use. Despite the concern for amenorrhea, some women have continued using the method. Literature shows that there is limited information on women's experiences of amenorrhea following use of Depo-Provera. A descriptive phenomenological research design was used to explore and describe women’s experiences of amenorrhea following use of Depo-Provera in order to understand how women experience amenorrhea and give meaning to the experience. Data were collected through in-depth unstructured interviews with six women, who were selected using purposive sampling. The interviews were conducted in Tumbuka language. Data analysis was done using Colaizzi’s method of analyzing descriptive phenomenological data. Five themes and some sub-themes emerged from data analysis. The themes were: "Lack of knowledge on cause of amenorrhea", "Fear of pregnancy", "Misconceptions associated with Depo-Provera Induced Amenorrhea", "Lack of proper counseling on amenorrhea resulting from Depo-Provera use" and "Amenorrhea not perceived as a problem when midwives provide adequate information". The themes showed that women accessing family planning services from Chitipa district hospital were not provided with information on amenorrhea resulting from using Depo- Provera. Hence, they expressed fear when they experienced the side effect. Participants stated that they were afraid of becoming infertile after using the family planning method, getting pregnant as well as amenorrhea itself. Their intention to discontinue using the method was largely associated with negative rumors, beliefs and misconceptions. The conclusion of the study is that there is need for midwives to provide information on amenorrhea resulting from Depo-Provera use. This will assist clients to understand that amenorrhea could occur as a side effect, and hence improve continued utilization of the method.

2	An assessment of uptake of long-acting family planning methods among women of childbearing age in Gweru district, Zimbabwe Mureyani, Shakespear January 2021 (has links) Master of Public Health - MPH / The problem of the unmet need for contraception continues to affect contraceptive uptake particularly the use of long-acting reversible contraceptives. Globally, Sub-Saharan Africa is reported to have the highest unmet contraceptive need. For example, nearly 50 % of married women of reproductive age, wanting to avoid pregnancy or plan when to have children, are reportedly not using contraception. More specifically, the prevalence of contraceptive use, in the Midlands Province of Zimbabwe where the Gweru District is situated, is estimated to be only 11%. This study examined the uptake of and reasons for use of different types of modern contraceptives; the factors influencing contraceptive use; discontinuation of use and non-use and reasons thereof for contraception and for long-acting reversible contraception in particular, amongst women in the Gweru district attending contraceptive services.

3	Quality of Life After Cardiac Valve Replacement Surgery Ammerman, Leah 01 January 2006 (has links) Quality of life (QOL) is an important issue that should be addressed by nurses in all areas of practice. One patient population for whom this is important is patients who have cardiac valve replacement surgery. Research has shown that patients over 70 who have prosthetic valve implantation have an improved QOL. However, no research has been done on the QOL for children or women of childbearing age. This deficit in nursing research must be addressed in order for patients to have access to the information they deserve before making the decision to pursue surgical treatment. Medical research has shown that women of childbearing age face numerous complications that may render them functionally infertile, and mental health research has shown that infertility can greatly affect a woman's psychological state. The purpose of this thesis was to analyze and synthesize recent research for QOL in these populations. Implications for nursing practice, education and research were also addressed.

4	Geometric approach to multi-scale 3D gesture comparison Ochoa Mayorga, Victor Manuel 11 1900 (has links) The present dissertation develops an invariant framework for 3D gesture comparison studies. 3D gesture comparison without Lagrangian models is challenging not only because of the lack of prediction provided by physics, but also because of a dual geometry representation, spatial dimensionality and non-linearity associated to 3D-kinematics. In 3D spaces, it is difficult to compare curves without an alignment operator since it is likely that discrete curves are not synchronized and do not share a common point in space. One has to assume that each and every single trajectory in the space is unique. The common answer is to assert the similitude between two or more trajectories as estimating an average distance error from the aligned curves, provided that the alignment operator is found. In order to avoid the alignment problem, the method uses differential geometry for position and orientation curves. Differential geometry not only reduces the spatial dimensionality but also achieves view invariance. However, the nonlinear signatures may be unbounded or singular. Yet, it is shown that pattern recognition between intrinsic signatures using correlations is robust for position and orientation alike. A new mapping for orientation sequences is introduced in order to treat quaternion and Euclidean intrinsic signatures alike. The new mapping projects a 4D-hyper-sphere for orientations onto a 3D-Euclidean volume. The projection uses the quaternion invariant distance to map rotation sequences into 3D-Euclidean curves. However, quaternion spaces are sectional discrete spaces. The significance is that continuous rotation functions can be only approximated for small angles. Rotation sequences with large angle variations can only be interpolated in discrete sections. The current dissertation introduces two multi-scale approaches that improve numerical stability and bound the signal energy content of the intrinsic signatures. The first is a multilevel least squares curve fitting method similar to Haar wavelet. The second is a geodesic distance anisotropic kernel filter. The methodology testing is carried out on 3D-gestures for obstetrics training. The study quantitatively assess the process of skill acquisition and transfer of manipulating obstetric forceps gestures. The results show that the multi-scale correlations with intrinsic signatures track and evaluate gesture differences between experts and trainees. 3D gesture comparison Multiscale curvature Curvature-torsion differential geometry complex trajectories quaternion trajectories quaternion projections quaternion metrics 3D trajectory smoothing curvature signature correlations qualitative skill transfer measure medical manipulative gestures nonlinear signatures anisotropic kernel filter curvature numerical stability quaternion smoothing kinematics motor skill transfer curvature signature torsion signature arc-length parameterization tensors Frenet-Serret quaternion framework nonlinear kernel filter geodesic distance finite difference methods differential convolution filter Savitzky-Golay filter least squares curve fitting curvature neighborhood multilevel curvature analysis medical training child bearing simulator robotic simulator motion tracking 3D electromagnetic trackers sequence comparison medical training
