Assessing the Patient Perspective on Marijuana Use During Pregnancy

Hankins, Kaley, Guhde, Isabel, Olsen, Martin H, MD 25 April 2023 (has links)
It has been noted that many pregnant women in East Tennessee are THC+ during routine urine drug screenings and/or at the time of delivery despite associations between poor fetal health outcomes both at delivery and neurodevelopmentally later in life. The purpose of this study is to assess beliefs and reasons for marijuana use during pregnancy, informational sources that influence beliefs, likelihood of use in future pregnancies, comfort level in talking with doctors, and associations with age, prior tobacco and/or prior marijuana use. Anonymous surveys consisting of 13 simple questions were distributed to female patients 18+ at three regional university-affiliated clinics. Of the 165 respondents, women less than 40 were three times more likely to perceive marijuana use while pregnant as safe and three times more likely to have used while pregnant. Patients with a history of both marijuana and tobacco use were more likely than any other category of respondents to perceive marijuana use during pregnancy as safe and to have plans to use in future pregnancies. The highest reasons for usage were nausea or vomiting (44%) and anxiety (44%). 45% of respondents felt comfortable talking with their doctors about marijuana use in pregnancy. Patients cited “family and friends (21%), “scientific articles “(21%), and “other” (24%) as sources of information on this subject. These results demonstrate an increased need for research and public information dissemination regarding marijuana use in pregnancy, as well as improving the physician-patient relationship to encourage evidence-based methods to relieve medical complaints during pregnancy.

Concentrations of insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-3 (IGFBP-3) in the plasma and milk of pasture-fed dairy cows in early lactation

Obese, Frederick Yeboah Unknown Date (has links) (PDF)
The involvement of IGFs and IGFBPs in mediating the effects of nutrition on the reproductive system in pasture-fed dairy cows and the requirement to improve assays for the determination of IGFs and IGFBPs in biological samples provided the stimulus for this thesis. The objectives of the studies were to validate a commercial ELISA to measure the concentrations of IGF-I in the plasma and milk samples from pasture-fed Holstein-Friesian dairy cows and investigate the variation in IGF-I and IGFBP-3 concentrations in blood and milk as well as investigate possible relationships between plasma concentrations of IGF-I and fertility.

Toxoplasmose experimental em caprinos machos, com ênfaser no sitema reprodutor /

Santana, Luís Fernando. January 2007 (has links)
Orientador: Alvimar José da Costa / Banca: Paulo Henrique Franceschini / Banca: Anderson Barbosa Moura / Resumo: Seis caprinos machos em idade reprodutiva foram selecionados e distribuídos em três grupos: GI dois caprinos mantidos como controle (placebo), GII dois caprinos inoculados com 1 x 106 taquizoítos de T. gondii (cepa RH) e GIII dois caprinos inoculados com 2 x 105 oocistos de T. gondii (cepa P). Periodicamente foram aferidos parâmetros clínicos, hematológicos e sorológicos, assim como avaliações parasitêmicas, além de exames andrológicos. A presença do parasito no sêmen e, também, nos tecidos do sistema reprodutor foi pesquisada por meio das técnicas de bioprova, PCR e imunohistoquímica. Surtos parasitêmicos foram detectados em todos os animais inoculados com taquizoítos ou com oocistos. A recíproca dos títulos sorológicos (RIFI) alcançou valores máximos de 4096 nos dois grupos de animais que receberam o Toxoplasma gondii. Pela técnica da bioprova foi possível revelar precocemente a presença do coccídio nas amostras seminais dos animais inoculados como taquizoítos (5°, 7°, 28°, 49°, 63° e 70° DPI) e um pouco mais tardiamente nas amostras seminais daqueles inoculados com oocistos (56° e 70° DPI). Pela PCR foi possível identificar, no sêmen, material genético de T. gondii, em cinco e em duas datas experimentais pós-inoculanção dos animais pertencentes aos grupos GII e GIII, respectivamente. Por esta mesma técnica foi possível, ainda, isolar material genético deste protozoário também em amostras teciduais (pool de próstata, testículo, vesícula seminal e epidídimo) dos caprinos 11 e 36 inoculados com taquizoítos e oocistos, respectivamente. Pela imunohistoquímica foi diagnosticado o T. gondii no epidídimo de todos os caprinos que receberam o protozoário. O isolamento de T. gondii, no sistema reprodutor de caprinos (sêmen e tecidos), sugere a possibilidade da transmissão sexual constituir uma importante via na disseminação desta zoonose tão difundida na caprinocultura mundial. / Abstract: Six goat males in reproductive age had been selected and distributed in three groups: GI - two goat noninoculated (control), GII - two goat inoculated with 1 x 106 tachyzoites of T. gondii (RH strain) and GIII - two goat inoculated with 2 x 105 oocysts of T. gondii (P strain). Periodically had been measured clinical parameters, hematologics and sorologics evaluations, as well as parasitemics, beyond andrologics examinations. The presence of the parasite in the semen, and also in tissues of the reproductive system was searched by means of the techniques of bioassay, PCR and immunehistochemistry (only for tissues). Parasitemia was detected in the two animals inoculated with tachyzoites and in the inoculated others two with oocysts. The reciprocal one of the sorologicys titles (RIFI) reached maximal level of 4096 in the two groups of animals inoculated with the Toxoplasma gondii. Using biossay technique was possible precociously to disclose to the presence of the coccidy in the seminal samples of animals inoculated with tachyzoites (5°, 7°, 28°, 4 9°, 63° e 70° DPI) and a little more delayed in the seminal samples of it inoculated with oocysts (56° e 70° DPI). For the PCR it was possible to identify to the genetic material of the T. gondii, in the semen in five and two experimental dates after-inoculanção of the pertaining animals to groups GII and GIII respectively. For this same technique was possible still to isolate material genetic of this protozoario also in tissues samples (pool of prostate, testícule, vesicula seminal and epididim) of goat 11 and 36 inoculated with tachyzoites and oocysts, respectively. By the immunehistochemistry was diagnosised T. gondii in epididim of all goats ones that had received the protozoario. The isolation of T. gondii, in the reproductive system of goat (semen and tissues), suggests the possibility of the sexual transmission to constitute...

Evaluating the Effectiveness of Using Thiel Soft-Embalmed Donors to Teach the Female Pelvic Exam to Medical Students

Patterson, Amy, LaRocque, Autumn, Holt, Abigail, Grubbs, Heather, Becker, Rob, Schreck, Arielle, MD, Abercrombie, Caroline, MD 04 May 2020 (has links)
At the Quillen College of Medicine, first year medical students are taught how to perform the female pelvic exam as part of the “Introduction to Physical Exam” course. Our previous research has found that students feel more confident and report a higher level of perceived transferability to live patients when learning the pelvic exam on soft-embalmed donors in comparison to low-fidelity mannequins. Our goal in this project was to incorporate soft-embalmed donors into the curriculum of first year medical students, making this teaching method available to all students, and objectively assess their skills as well as their retention. During the “Introduction to Physical Exam” course, high fidelity soft embalmed donors were available for students to practice the female pelvic exam with instruction from attending physicians. After learning exam techniques, all 67 students were given a survey to assess their confidence, perceived transferability, and preference for either soft embalmed donors or mannequins. They were also invited back the following week to assess their short term retention and ability to accurately perform the pelvic exam, with the option of using communication skills learned elsewhere in the ETSU curriculum. Thirteen students returned for this follow-up session and completed surveys to reassess their experience. We plan to follow this cohort of students throughout their medical school career to assess long term retention. All return participants felt they retained the pelvic exam knowledge learned the week prior, with 61.54% agreeing, and 38.46% strongly agreeing. Most felt prepared to now do a pelvic exam on a live patient (53.85% agreed, 38.46% strongly agreed). Students also reported that feedback on their communication and procedural skills was beneficial to the learning process. The use of high fidelity soft embalmed donors in medical education provides students with a realistic model to learn and become confident in performing pelvic exams. We have seen that this education model helps them retain their knowledge on pelvic exam technique. We look forward to following this cohort of students to see if this retention of knowledge persists into their third year of medical school.

The effects of artificial and natural sweeteners on various physiological systems

Rahiman, Farzana January 2011 (has links)
This study aimed to investigate the effects of commercially available natural (sugar cane molasses, white sugar and brown sugar) and artificial (Canderel™, Equal™, Natreen™, Sweetex™, Splenda™ and Swheet™) sweeteners on various physiological systems. The artificial sweeteners tested in this study may be categorised into their respective groups based on their primary ingredient. The brands Canderel™ and Equal™ contain aspartame, Natreen™ and Sweetex™ consist of saccharin and Splenda™ and Swheet™ are composed of sucralose. The inclusion of artificial or natural sweeteners in the human diet has been continually debated and their implication in the development of certain diseases has raised concern regarding their safe use. Therefore, it is necessary that these food products be subjected to a battery of tests to determine adverse effects on human health.
