The Effects of Berberine vs. Metformin for Decreasing Waist Circumference and Serum Lipid Levels in Women with Polycystic Ovarian Syndrome
No full textBackground: Polycystic ovarian syndrome (PCOS) is a highly prevalent disease that effects both metabolic and reproductive systems in women. PCOS is associated with a high incidence of obesity, insulin resistance, hyperandrogenism, hyperlipidemia, menstrual cycle dysfunction, and infertility. Diagnosis is made using the Rotterdam Criteria, and current accepted medical management of PCOS includes lifestyle changes such as diet and exercise, oral contraceptive pills (OCP), metformin (MET), and bariatric surgery. a. The aim of this systematic review is to assess the effect of berberine on waist circumference and cholesterol levels.
Methods: A comprehensive literature search was done using Medline, Web of Science, and Clinical key using keywords PCOS or polycystic ovarian syndrome and berberine. Relevant studies were critically assessed using GRADE.
Results: Two studies were chosen for this systematic review, one randomized control trial, and one case control study, that adequately assessed the effects of berberine compared to metformin as well as alone for the treatment of PCOS. The RCT showed that BBR appears to have greater effect than metformin on decreasing waist circumference and waist-to-hip ratio, total cholesterol, triglycerides, and low-density lipoprotein after 3 months of treatment. The case control study showed that BBR therapy caused a statistically significant decrease in waist circumference, LDL levels, and triglycerides in women with PCOS after 6 months of treatment. These studies resulted in a low quality of evidence overall.
Conclusion: BBR caused a greater decrease in waist circumference and lipid profile than MET. This effect is additive when combined with lifestyle changes such as diet and exercise. More studies are needed to evaluate the long-term efficacy of BBR on weight loss and BMI. Overall as weak recommendation, berberine can be considered as a suitable alternative to metformin for the treatment of polycystic ovarian disease

The Future of Cataloging (for the Rest of Us): Forecasting for Production-Level Cataloging
Get PDFFor decades, catalogers have lived in a place of change. We’ve been in a nearly continual shift ever since library catalogs moved to digital environments, and before that as concepts and new formats emerged. In the past, many of these changes have taken years or decades to implement locally, let alone implement on a national or global scale. Our era in cataloging is no different. The implementation of RDA, the shift away from the MARC record, and increasing interest in linked data (among myriad other factors) are beginning to coalesce into a discernible future. This is an exceptional time when we can begin to imagine a practical future for the catalogers, copy catalogers, and staff-who-occasionally-catalog who might not always be privy to the inner workings of committee meetings, task forces, or academic conferences.
In this article, I will look specifically at how copy cataloging will likely look in the near future. The pace of evolution in cataloging is generally glacial, so by “near future,” I’m thinking of the next 20 years. I’ll also summarize current developments with RDA, linked data, BIBFRAME, and other factors, and discuss their impact. I will use the terms “catalogers” and “copy catalogers” interchangeably, since most of us are both or either, depending on the day or hour
Three Tips for Creating Local Technical Services Trainings
No full textOne challenge that many Technical Services supervisors face is providing little or no-cost training opportunities for their staff. With limited professional development budgets and constant change in Technical Services workflows, it can be difficult for libraries, particularly public and school libraries, to keep up with staff education needs. The purpose of this article is to address common issues encountered in creating little or no-cost local trainings on a variety of topics, ranging from concrete tasks to complex theory. By the end of this article, readers should be able to navigate common issues faced in creating and implementing locally created/adapted staff instruction. Readers who are interested in free professional development resources should utilize email lists and professional organization resources.
I am a senior librarian in the Technical Services division of the Tigard Public Library whose primary responsibility is cataloging. Over the past four years, I have worked with colleagues at the Washington County Cooperative Library Services (WCCLS) Automation office and with staff at other WCCLS member libraries in order to provide countywide professional development opportunities for Technical Services staff responsible for cataloging and serials management. These trainings have included in-person instruction with customized guides, gamified self-guided exercises, and basic introductions to complex postMARC concepts. Each of these professional development opportunities came with unique challenges and led to some lessons that I would like to share, including (I) keeping trainings simple and focused, (II) assigning local experts if one does not already exist and (III) relating complex terms to existing practices
Micro Actions Support Culture of Equity, Diversity, and Inclusion in an Academic Library
No full textAs student workers at the Oregon Health & Science University (OHSU) Library, we wanted to better understand the role of equity, diversity, and inclusion (EDI) in an academic library. In conversations with staff, both in person and through emailed questions and responses, we have found that personal values are a driving force behind many smaller, continuous staff actions in promoting EDI throughout different departments.
Across libraries and larger institutions, EDI values are often built into larger strategic visions. However, guidance for the practical implementation of these values may be less specific, leaving staff to make their own decisions on how to achieve these larger institutional goals. Diversity and inclusion are top values at OHSU.... However, there are no clear policies or guidelines for how to do this. For example, within the library’s collection development policy, there is no mention of EDI (Oregon Health & Science University Library, 2018). This does not mean, however, that there is not a culture of EDI at OHSU Library
Let Me Save You Some Time... On Valuing Travelers\u27 Time in Urban Transportation
No full textSystems of urban transportation are largely shaped through planning practices. In transport economics, the benefits of infrastructure investments consist mainly of travel time savings calculated using monetary values of time. The economic interpretation of the value of travel time has significantly shaped our urban environment and transportation schemes. However, there is often an underlying assumption of transferability between time and money, which arguably does not sufficiently take into account the specific features of time. In this paper, we analyze the various properties of time as an economic resource using findings in behavioral economics and psychology. Due to limitations in the standard model, it is proposed that an alternative model value should be investigated in which time rather than money is the primary carrier of and the basic features of such a model are outlined. An improved understanding the nature of time as a source of utility puts us in a better position to determine what aspects of time matter. Additionally, the analysis can be applied to further develop modeling where value of time plays a significant role; such as new models for the planning of urban transport
The Street Performer
Get PDFAward for Best Creative Work
2018 Northwest Undergraduate Conference in the Humanities
Loosely based off a group of female abstract artists from the late 1800s, this fictional piece is centered around the protagonist’s obsession with one particular subject in her art—the medium being filmmaking—and exploring the rather idolized projection she has created for this individual. This story attempts to examine the life of an artist who is swept up in an unconscious state of fiction, continuously re-creating and shifting her perception of people (the street performer, specifically)—often as a reflection of her own self and frustrations. This is done through the use of film, and highlighting specific images as we might see them in movies. There is a sense of self-awareness in both filming, and being watched or recorded
Effects of Light Illumination on Ocular Responses and Visual Comfort
Get PDFBackground: Artificial light sources such as Light-emitting Diode (LED) emit more intensive blue light (460 to 490 nm) and are with a wavelength distribution deviating from the peak wavelength of 550 nm in natural sun light. The present study examined how cold and warm LED lamps with high- and low-blue light emission differently affected objective ocular responses and subjective viewing symptoms. Methods: 34 adults with normal or correct-to-normal vision read printed continuous text with one of three lamps (LED 4000 K, LED 6500 K and OLED 4000 K) generating 50 and 110 Nits for 60 mins respectively while their pupil size, accommodative response (increase of refractive power or the shortening of focal distance) and vergence angle (the degree of eyes turning inward) were continuously recorded at 50 Hz. Before and after reading their viewing symptoms were also surveyed, as well as overall discomfort at every 10-min interval. Results: with a lower luminance of 50 Nits, LED 4000 resulted in greater vision-related symptoms (blurry, double vision, eye pain) than OLED 4000 and LED 6500; this was accompanied by smaller pupil, larger accommodative lag, and larger vergence lag. With higher luminance of 110 Nits, LED 6500 and 4000 resulted in greater cognitive and fatigue symptoms, but not visual symptoms, compared to OLED 4000. Conclusions: LED at a lower illumination level causes insufficient focal distance and eye alignment and consequent blurred and double vision, as well as eye discomfort. The expected physical and cognitive fatigue associated with blue light emerges at a higher luminance. OLED is a better light source because it emulates normal light. As a result, it is more comfortable for sustained near work and allows better visual efficiency
