Eating Disorders and Pregnancy: The Case of Anorexia

引用

Open Journal of Psychiatry 2024年第4期14卷 353-373页

作者： Anne-Sophie gautier Psychiatrist/Child Psychiatrist CH Denain Denain France

The question of the link between pregnancy and eating disorders is an important question. At the moment, there are few concrete answers for these patients. Despite common fertility challenges, patients who suffer from ED are able to access maternity. ED and pregnancy can either have an easy evolution or experience a lot of trouble. Many studies describe obstetrical and foetal complications (low birthweight, inadequate intra-uterine growth, small head circumference, miscarriage, caesarean section). Those patients are frequently reluctant to address their disease with their specialist, who also often doesn’t know how to screen the signs. The lack of official data to train the specialists further increases these difficulties. However, ED are frequent in the general population and young patients are likely to eventually want to become mothers. It is thus essential to know how to screen those patients early and accurately to improve their treatment and care. Eating disorders impact the pregnancy, the delivery and the postpartum as well as the growth of the baby. It is an important public health problem. The evolution from being a woman to becoming a mother is a difficult one, and even more so when the women is suffering from ED. Those patients must handle their nutritional fears, the anxiety about their body changing with pregnancy and the daily challenges. The early interactions with their baby have consequences on their development. It seems necessary to evaluate how to improve the screening and the patient care in ED patients. Screening should begin from the pregnancy desire to the postpartum. This patient care should be based on a multidisciplinary care team.

Comparative Study of the Types of Photovoltaic Panels Used in Solar Pumping Systems in Dry Tropical Zones: Case of Adamawa Region in Cameroon

引用

Open Journal of Energy Efficiency 2024年第3期13卷 79-87页

作者： Boussaibo Andre Waoudowa Kande Veronique Ndjiya Ngasop Stephane gautier Kitmo Department of Electrical Engineering University Institute of Ngaoundr Ngaoundr Cameroon Department of Electrical Energy and Automation National School of Agro-Industrial Sciences Ngaoundr Cameroon Department of Physics University of Ngaoundr Ngaoundr Cameroon

In the dry tropical zone where access to water is increasingly difficult for populations, solar pumping units are increasingly installed to provide water to population. In the local market, there are essentially two types of solar panels, namely monocrystalline and polycrystalline. However, the part of the local market is more dominated by the polycrystalline panel. In this work, comparative studies are carried out in order to characterize the two types of solar panels with regard to local constraints. Tests were carried out over the course of the sun to establish the performance of each type. The panels used have the same electrical characteristics and are connected to loads with same characteristics. Under the set operating conditions, the monocrystalline panel presents more performance than the polycrystalline panel. Although the local market is dominated by the polycrystalline panel, dust deposition tests on the surface of the panels show that the performance of the polycrystalline panel is more affected compared to the performance of the monocrystalline panel.

Rabies, a viral zoonosis, is one of the neglected tropical diseases (NTDs) that mainly affects poor and vulnerable populations. Human rabies is endemic in Benin. Although listed among the notifiable diseases, it nevertheless remains a neglected and under-reported disease. The objective of this study was to investigate the determinants of knowledge of rabies risk among subjects exposed to human rabies by dog bites in the Plateau department of Benin. Methods: This was a cross-sectional study with an analytical aim which involved a sample of 900 people aged at least 18 years old chosen randomly and residing in the Plateau department for at least six months. A pre-tested and validated digital questionnaire served as a data collection tool. Data analysis was done with R 3.4.1 software. The prevalence ratio was used as a measure of association. The confidence threshold was set at 5%. We carried out a multiple logistic regression using the likelihood ratio (top-down approach) in order to identify the main factors which influenced the good knowledge of human rabies in the population of Plateau. Results: In the study population, 80.89% of the subjects surveyed lived in a rural area. The sex ratio (Male/Female) was 1.11. The average age of the subjects was 40.24 ± 14.52 years. The prevalence of dog bites was 4.11% (95% CI = [3.00;5.63]) or 37 subjects bitten. After evaluation of knowledge of rabies risk in the study population, the main factors which positively influenced good knowledge of human rabies were age (p linear trend 0.01), residence of the subject in the municipality of Pobè (ORa = 8.34;95% CI = 0.83 - 1.23;p l dwelling (ORa = 17.95;95% CI = 13.12 - 49.58;p l level of at least secondary (ORa = 5.53;CI 95 = 3.06 - 10.15;p = 0.01), the existence of a veterinary center (ORa = 3.66;CI 95 = 1.07 - 12.43 p = 0.01) and knowledge of a dog bites victim (ORa = 6.55;95% CI = 2.73 - 8.25;p lusion: This population study confirm

Quantum vortices get stretched

Since its discovery, superfluidity [1,2] remains one of the most remarkable phenomena in quantum physics. The onset of the quantum regime in liquid helium is visually striking, when the fluid flows without dissipation or detaches from a rotating bucket, remaining still upon soft rotations. The same phenomenon is present in the context of ultracold bosonic quantum gases where, most of the time, superfluidity walks hand-in-hand with the transition to Bose−Einstein condensation [3].
