402 surplus for the patient, €-25.950 for health care and €-23.548 in total. Conclusion Projected cost savings for OPAT-treatment of PJI are substantial. However, OPAT within the current Belgian system was significantly more expensive for the patients. This can be attributed to the Belgian health insurance system; its current reimbursement regulations prevent OPAT from truly making a breakthrough in Belgium.Experiments on isolated mammalian gut are essential components of the physiology curriculum worldwide. Over the years, these routine experiments have been largely replaced by simulation modules, to reduce the euthanization of animals for understanding established facts and mechanisms in gut physiology. However, a medical undergraduate needs hands-on training to handle a living tissue to have a better understanding of physiology. The present sourcebook update describes the use of avian gut, which is usually discarded in abattoirs, as an effective replacement of mammalian gut to understand basic gut smooth muscle physiology. The avian gut can be used to study the effect of various drugs and ions as used in mammalian gut experiments. The experiment protocol described in the update can be performed by students of basic sciences and medical students using minimal laboratory set up and at low cost, producing results comparable to mammalian gut experiments. Ethical permissions may not be necessary; however, the disposal of tissue waste has to follow proper guidelines.As literature indicates, historic racism and implicit bias throughout academia have been profound metrics leading to a lack of diversity, as related to people from underrepresented groups according to race and ethnicity, among biomedical sciences graduate students in U.S. universities. Recognizing such challenges, a team of biomedical scientists and inclusivity educators developed and implemented a pilot training program within an academic health sciences center as an initial step to educate faculty and staff regarding their roles in the promotion of an inclusive academic environment, receptive to all students, including underrepresented students. The 3-h workshop included didactic modules, videos, teaching modules, and active attendee participation. Faculty and staff were presented common terminology and ways to promote the development of an inclusive and diverse academic workforce. Compared with pre-workshop, post-workshop survey results indicated a statistically significant improvement in attendee knowledge of correctly identifying definitions of "implicit bias," "status leveling," "color-blind racial attitudes," "tokenism," and "failure to differentiate." Additionally, by the end of the workshop, participants had a statistically significant increase in self-perceptions regarding the importance of improving diversity and recognizing biases and stereotypes in graduate education, knowing what to say when interacting with people from different cultures, and the ability to acknowledge bias when mentoring students from groups underrepresented in the biomedical field. MDL28170 This preliminary initiative was successful in the introduction of faculty and staff to the importance of fostering an inclusive academic environment and thereby developing a diverse workforce.Access to knowledge has never been easier in the internet age, and so it is important that students develop skills to discriminate undependable information from reliably investigated research. We have created an exercise that teaches good research practice by exploring the history, ethics, and design of clinical trials. Students apply their understanding of these principles through an assessed systematic review and meta-analysis (SRMA) exercise. Here, a clinically themed hypothesis is tested using a structured literature search in conjunction with an eligibility matrix to map study design, ethics, subject selection, randomization and blinding, methodological standards, study power, and other potential sources of interstudy heterogeneity. Data extracted from selected studies are used to produce a forest plot with an aggregated effect size, confidence range, and measure of interstudy heterogeneity. A funnel plot is then used in conjunction with the eligibility matrix to evaluate study bias tendency, and, in this way, students reflect on the factors that promote disparate conclusion-making among studies with a common research focus. This exercise produced a normally distributed grade-profile across three academic-year cohorts, and comparison of individual exercise grade with year-long aggregated average suggested students who performed less well on conventional assignments engaged successfully with the systematic nature of this assessment. Those opting to use this format for their final-year capstone project also performed above their grade point average from the preceding year. We suggest that SRMA offers a readily applied method for students to quantitatively explore how differences in experimental research practices influence study dependability.Physiology students grapple with large amounts of subject content and hence memorize facts to pass examinations. In parallel, students display limited critical-thinking and creative skills, integration abilities, and/or a deeper engagement with subject content. This study aimed to assess the feasibility of introducing active learning methods (cooperative learning) in a relatively large class to final-year undergraduate physiology students (Bachelor of Science stream) at Stellenbosch University in South Africa. An assignment designed to enhance active and engaged learning was made available to the students (n = 225) during the second week of a 5-wk cardiovascular physiology series of lectures. Students were instructed to freely form working groups (n = 3/group) and the assignment was due by the end of the module. Student groups were expected and encouraged to continuously work on the assignment (outside class time). Three cooperative learning slots were also created during class time, with the lecturer and postgraduate students acting as guides. After the module, students anonymously completed an electronic questionnaire. This study revealed three major findings in terms of implementing cooperative learning in large classes within a South African context, i.e., 1) relatively good reception by students with some indication of group work; 2) it is logistically feasible in relatively large classes, although adequate support is crucial; and 3) additional measures need to be adopted to ensure its success.The relationship between pH, pKa, and degree of local anesthetic ionization is quantified by the Henderson-Hasselbalch equation. As presented in standard textbooks, the effect of pH on the degree of ionization of any particular local anesthetic is not immediately clear due to the x-axis displaying pH - pKa, which requires conversion to pH, based on the pKa for each local anesthetic, a complex process. We present a graphical solution that clarifies the interrelationships between pH, pKa, and degree of ionization by plotting pKa on the x-axis versus the percentage of unionized local anesthetic on the y-axis. The vertical intercept from the x-axis to the pH curves allows rapid and accurate estimation of the degree of ionization of any local anesthetic of known pKa.After 100 years of theoretical treatment of speckle patterns from coherent illumination, there remain some open questions about the nature of ultrasound speckle from soft vascularized tissues. A recent hypothesis is that the fractal branching vasculature is responsible for the dominant echo pattern from organs such as the liver. In that case, an analysis of cylindrical scattering structures arranged across a power law distribution of sizes is warranted. Using a simple model of echo strength and basic transformation rules from probability, we derive the first order statistics of speckle considering the amplitude, the intensity, and the natural log of amplitude. The results are given by long tailed distributions that have been studied in the statistics literature for other fields. Examples are given from simulations and animal studies, and the theoretical fit to these preliminary data support the overall framework as a plausible model for characterizing ultrasound speckle statistics.Waterbirth is associated with a less painful childbirth, enhanced couples' intimacy, and positive feelings toward women's bodies and sexuality. In a qualitative, descriptive case study involving 21 participants, we examined the sexual experiences-during childbirth and postpartum-of women who had a waterbirth in a hospital environment. Women discussed their sexuality in the intrapartum and postpartum period after having a waterbirth in public or private hospitals. Two main themes were developed from the data analysis 'women's sexual pleasure during waterbirth' and 'sexuality after childbirth'. Experiences included transcendence during waterbirth, a feeling that it represented a unique experience, and couples' more positive feelings about intimacy. The shared representations of women suggest that waterbirth can be a calming, joyful event for couples. During this process, they felt that it was a loving, shared event. In addition, after childbirth women experienced positive feelings toward their bodies and sexuality (including orgasm), as well as closer intimacy with their partners.Background. A literature review of the use of video systems for magnification has suggested that so far, this novel magnification system has only been used to perform arterial anastomoses. The aim of this study was to evaluate the use of 2 low-cost methods of video-assisted magnification in microvascular venous anastomosis in rats. Methods. Thirty rats were randomly divided into 3 matched groups according to the magnification system used the microscope group, with venous anastomosis performed under a microscope; the camcorder system group, with the procedures performed under a high-definition Handycam HDR-XR160; and the Photographic camera group, for which procedures were performed with an EOS Rebel T3i photographic camera. In both video system groups, a magnification system was connected to a 42-in. television by an HDMI cable. We analyzed weight, venous caliber, total surgery and anastomosis time, patency immediately and 14 days postoperatively, number of stitches, and histological analyses. Results. There were no significant differences between the groups in weight, venous caliber, or number of stitches. Anastomosis under the video systems took longer. Patency rates were similar between the groups, except for the photographic system group that has a lower patency rate at 14 days. The histological analyses were similar in all groups. Conclusion. It is possible to perform a venous anastomosis in rats through video system magnification, with a satisfactory success rate comparable with that for procedures performed under microscopes; however, the kind of video system has a great influence on the final patency.Arterial stiffness (AS) and obesity are recognized as important risk factors of cardiovascular disease (CVD). The purpose of this study was to investigate the relationship between AS and obesity. AS was defined as high augmentation index (AIx) and low C1 and C2 in participants enrolled in the Multi-Ethnic Study of Atherosclerosis at baseline. We compared AIx, C1, and C2 by body mass index (BMI) ( 40 kg/m2 had 5.4% lower AIx (mean difference [Δ] = -0.82%; 95% CI -1.10, -0.53), 15.4% higher C1 (Δ = 1.66 mL/mmHg ×10; 95% CI 1.00, 2.33), and 40.2% higher C2 (Δ = 1.49 mL/mmHg ×100; 95% CI 1.15, 1.83) compared to those with a BMI less then 25 kg/m2 (all p for trend less then 0.001). Participants with a WHR ⩾ 1 had 5.6% higher C1 (∆ = 0.92 mL/mmHg ×10; 95% CI 0.47, 1.37) compared to those with a WHR less then 0.85. The WHR had a significant interaction with age on AIx and C2, but not with BMI; the inverse relationships of the WHR with AIx and C2 were observed only in participants less then 55 years between the normal (WHR less then 0.
