Poverty And Commercial Surrogacy In India: An Intersectional Analytical Approach, Sheela Suryanarayanan Sep 2023

Poverty And Commercial Surrogacy In India: An Intersectional Analytical Approach, Sheela Suryanarayanan

Dignity: A Journal of Analysis of Exploitation and Violence

The destination and source countries for commercial surrogacy match world patterns of inequality. India, Nepal, Thailand, Mexico, and Cambodia banned commercial surrogacy, moving the market to other less-developed countries in South Africa and South America. India had a commercial surrogacy boom until exploitative factors led to the passage of the Surrogacy (Regulation) Bill in 2019, which banned the practice. This paper examines surrogacy's monetary, health, and emotional effects on 45 surrogate mothers in Gujarat State, India. The study revealed that a majority (63%) of the very poor women remained very poor post-surgery. Surrogate mothers in poor households had to do …


Improving Timeliness Of Palliative Care Referrals Within The Intensive Care Unit: A Quality Improvement Project, Stephanie Fiore Sep 2023

Improving Timeliness Of Palliative Care Referrals Within The Intensive Care Unit: A Quality Improvement Project, Stephanie Fiore

DNP Projects

Significance and Background: Palliative care (PC) services are often underutilized in the ICU. There is a lack of understanding of PC by providers, staff, patients, and families which then leads to difficulty obtaining appropriate and adequate referrals to the PC team. In the ICU practice setting, the current process for palliative care referrals (PCRs) has the attending physician as the only individual to initiate a PCR referral. Another element missing from the current process is a criteria trigger tool that other disciplines, including nursing, can use to assess the patient’s need for PCR in the first 48 hours of admission. …

Primary Angiitis Of The Central Nervous System Presenting As Sudden Vision Loss In A Young Patient, Ayisha Farooq Khan, Lubna Jafri, Saad Shafqat

Pakistan Journal of Neurological Sciences (PJNS)

Primary angiitis of the central nervous system is a rare disorder that primarily affects the cerebral vessels and can prove to be a diagnostic challenge to the clinicians. It can present with a variety of clinical manifestations and lacks the evidence of any systemic disease. Digital subtraction angiography is often necessary to confirm the diagnosis of cerebral vasculitis but in cases where it may fail to do so, brain biopsy is eventually required. Obliviousness to this condition may lead to false management strategies and hence it is imperative to make an accurate diagnosis to facilitate proper treatment that mainly includes …

Non-Contact Optical Spectroscopy For Tumor-Sensitive Diffuse Reflectance And Fluorescence Measurements On Murine Subcutaneous Tissue Models: Monte Carlo Modeling And Experimental Validations, Zahid Hasan, Pranto Soumik Saha, Madison O. Korfhage, Caigang Zhu

Markey Cancer Center Faculty Publications

Fiber-optic probes are commonly used in biomedical optical spectroscopy platforms for light delivery and collection. At the same time, it was reported that the inconsistent probe- sample contact could induce significant distortions in measured optical signals, which consequently cause large analysis errors. To address this challenge, non-contact optical spectroscopy has been explored for tissue characterizations. However, existing non-contact optical spectroscopy platforms primarily focused on diffuse reflectance measurements and may still use a fiber probe in which the probe was imaged onto the tissue surface using a lens, which serves as a non-contact probe for the measurements. Here, we report a …

Exploring Bidirectionality In Us Pediatric Global Health Programs, Anik Patel, Pauline Kamau, Ashley Combs, Megan Mchenry

Posters

Introduction: Over the last two decades, GH programs have offered experiences at partner sites through established global health partnerships (GHPs). Historically, GHPs have been one-directional, favoring partners from resource-rich settings. These partnerships are now being reevaluated through the lens of equity and decolonization. We seek to understand how US pediatric GH faculty define the concept of “bidirectionality”, assess perspectives on their institution’s practice of bidirectional activities, and explore perceived benefits and challenges to prioritizing bidirectionality within their own GHPs. Methods: This is a cross-sectional qualitative survey study on bidirectionality of 206 AAMC-accredited US pediatric residency programs. 24 survey responses from …

Hyperkalemia refractory to standard temporization measures can be life-threatening, and urgent hemodialysis is often utilized as a final resort. Our patient presented with hyperkalemia that was multifactorial in etiology, with acute kidney injury complicated by adrenal insufficiency. Her hyperkalemia was refractory to temporization and excretion agents, and hemodialysis was being considered. Given a recent infection, surgery, and borderline hypotension with low adrenocorticotropic hormone, there was a concern for adrenal insufficiency. However, a full investigation for secondary adrenal insufficiency via magnetic resonance imaging could not be conducted as the patient suffered from claustrophobia. Continued concern for adrenal insufficiency prompted the initiation …

Hla-Ii Alleles Influence Physical And Behavioral Responses To A Whey Allergen In A Transgenic Mouse Model Of Cow's Milk Allergy, Danielle L. Germundson, Suba Nookala, Nicholas A. Smith, Yassmine Warda, Kumi Nagamoto-Combs

Biomedical Sciences Faculty Publications

The symptoms of food allergies vary significantly between individuals, likely due to genetic determinants. In humans, allergy development is initiated by antigen-presenting cells via class II human leukocyte antigen (HLA-II). The HLA-II gene is highly polymorphic, and its allelic variance is thought to influence the susceptibility of individuals to a particular allergen. However, whether antigen presentation by different HLA-II variants contributes to symptom variation is not clear. We hypothesized that HLA-II allelic variance affects symptom phenotypes, including immediate physical reactions and delayed behavioral changes, in individuals with food hypersensitivity. To test our hypothesis, male and female mice of three transgenic …

Streptococcus pyogenes (Group A Streptococcus, GAS) bacteria cause a spectrum of human diseases ranging from self-limiting pharyngitis and mild, uncomplicated skin infections (impetigo, erysipelas, and cellulitis) to highly morbid and rapidly invasive, life-threatening infections such as streptococcal toxic shock syndrome and necrotizing fasciitis (NF). HLA class II allelic polymorphisms are linked with differential outcomes and severity of GAS infections. The dysregulated immune response and peripheral cytokine storm elicited due to invasive GAS infections increase the risk for toxic shock and multiple organ failure in genetically susceptible individuals. We hypothesized that, while the host immune mediators regulate the immune responses against …
