Faculty, Staff and Students Publications

COVID-19 morbidity and mortality are driven by poor immune regulation. Narrowband ultraviolet B (NB-UVB) phototherapy is standard of care in a number of immune-dysregulated diseases. To assess the efficacy of NB-UVB phototherapy for improving COVID-19 outcomes in high-risk, hospitalized, we developed the Adaptive Photo-Protection Trial. This is a multi-center, prospective, double-blinded, randomized, placebo-controlled trial. The pilot phase results are reported here. Consecutive patients admitted with a positive COVID-19 PCR were screened for eligibility. Enrolled subjects were computer randomized 1:1 to NB-UVB or placebo phototherapy. Subjects were treated daily with escalating doses on 27% of their body surface area for up …

Adipose tissue is a promising target for treating obesity and metabolic diseases. However, pharmacological agents usually fail to effectively engage adipocytes due to their extraordinarily large size and insufficient vascularization, especially in obese subjects. We have previously shown that during cold exposure, connexin43 (Cx43) gap junctions are induced and activated to connect neighboring adipocytes to share limited sympathetic neuronal input amongst multiple cells. We reason the same mechanism may be leveraged to improve the efficacy of various pharmacological agents that target adipose tissue. Using an adipose tissue-specific Cx43 overexpression mouse model, we demonstrate effectiveness in connecting adipocytes to augment metabolic …

Emicizumab-Kxwh: A Critical Review, Kiera O'Leary

International Undergraduate Journal of Health Sciences

The first descriptions of haemophilia A were reported in the second century AD, with the first modern description by John Conrad Otto in 1803. Historically, the natural history of haemophilia A was associated with very high rates morbidity and mortality, often following trivial accidents. Although treatment options for haemophilia A have been revolutionised in recent decades, haemophilia A remains a hereditary disease of concern and factor replacement products remain the mainstay of treatment.

As such, patients with haemophilia can carry huge burdens, particularly when a complication such as a FVIII inhibitor is present. A recently approved novel therapeutic, Emicizumab-kxwh, has …

A Review Of The Pathogenesis, Clinical Features And Diagnostic Indicators Of The Novel Condition Vaccine-Induced Thrombotic Thrombocytopenia, Ada Fleming

International Undergraduate Journal of Health Sciences

The introduction of vaccination against SARS-CoV-2 infection was a welcome and significant event in the COVID-19 pandemic. While vaccine administration was for the most part successful, it did come with the emergence of a novel condition, Vaccine-Induced Thrombotic Thrombocytopenia (VITT). This condition presents after the administration of adenoviral vector-based vaccines against COVID-19, causing thrombocytopenia and thrombosis in affected individuals. There have been 10 suspected cases of VITT in Ireland. While its mechanism is not fully understood, the condition is characterised by the presence of Platelet Factor 4 (PF4) antibodies. There are several laboratory indicators which may suggest that a patient …

Conscious And Unconscious Bias: The Hidden Pandemic Of Biases In Healthcare Exacerbated By Covid-19, Ibtisam Rauf, Abigail Hartmann, Alexandre Koumtchev, Syed Anjum Khan, Rahul Kashyap

HCA Healthcare Journal of Medicine

Background

There are limited data on unconscious bias in healthcare, but there is consistent evidence that it alters clinical decision-making. COVID-19 exacerbated many pre-existing disparities, and this paper seeks to identify, deconstruct, and propose mitigation strategies for a few of them.

Discussion

Five of the largest disparities amplified by the pandemic are discussed in this paper. Older people, Black people, uninsured people, rural communities, and people with lower education levels have been disproportionally affected in both morbidity and mortality.

Conclusions

The disparities discussed above did not occur in a vacuum but are the result of systemic issues. Equity starts with …

Is There A Bias Toward Unvaccinated Covid-19 Patients?, Abbas B. Jama, Anwar Khedr, Hisham Mushtaq, Nitesh K. Jain, Thoyaja Koritala, Syed Anjum Khan

HCA Healthcare Journal of Medicine

With more than 22% of the United States still not vaccinated for COVID-19, we are trying to shed some light on whether there is any bias when treating unvaccinated COVID-19 patients. We highlight several reports where some individuals or organizations displayed possible bias, whether implicit or explicit. We examine the legal and ethical implications of these biases and offer a general overview of how to tackle them.

The Vaginal Microbiota, Indah Kencana, Satya Wydya Yenny

Journal of General - Procedural Dermatology and Venereology Indonesia

The vagina is an ecosystem consisting of various species of microorganisms (microbiota) that play important role in maintaining vaginal health. The vaginal ecosystem includes a variety of species classified into aerobic and anaerobic microorganisms which are vaginal microbiota (VMB). In the vagina of a healthy woman, 70% of normal microbiota is dominated by the Lactobacillus species. Lactobacillus is a Gram-positive, anaerobic bacterium, and belongs to the group of lactic acid bacteria (LAB). LAB produces lactic acid which plays a role in maintaining vaginal acidity at pH

Bacterial Sensitivity Pattern To Antibiotics In Acne Vulgaris At Universitas Sumatera Utara Hospital Medan, Indonesia In 2019, Lovena Sari, Nelva Karmila Jusuf, Imam Budi Putra

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: The association between psoriasis and metabolic syndrome is appealing as the two may share a similar cross-linking systemic inflammation process. The inflammation processes occurring in obesity and psoriasis may aggravate one another. This raised the question of whether a low-calorie diet would possibly reverse the aforementioned process. This study aims to determine whether calorie restriction reduces psoriasis area and severity index (PASI) in obese patients with moderate-to-severe psoriasis receiving conventional treatment compared to no calorie restriction.
Methods: We searched Pubmed/Pubmed Central, ScienceDirect, Cochrane library, EBSCOhost, and Scopus databases using keywords derived from our clinical question. The inclusion …

Psychological Well-Being In Childhood And Cardiometabolic Risk In Middle Adulthood: Findings From The 1958 British Birth Cohort, Julia K. Boehm, Farah Qureshi, Laura D. Kubzansky

Psychology Faculty Articles and Research

Childhood adversity is linked to poor cardiometabolic outcomes, but less is known about positive childhood factors. Using data from 4,007 members of the 1958 British Birth Cohort, we investigated whether children with greater psychological well-being had lower adulthood cardiometabolic risk. At age 11, participants wrote essays about their future. Two judges rated each essay for nine psychological well-being items (Finn’s r = .82–.91), which were combined into a standardized overall score (Cronbach’s α = .91). When participants reached age 45, nurses assessed their blood pressure, heart rate, lipids, glycosylated hemoglobin, fibrinogen, and C-reactive protein, which were standardized and summed for …

Recent Progress In Immunotherapy For Skin Cancer, Fadhli Aulia Mughni, Rinadewi Astriningrum, Aida Sd Hoemardani, Kusmarinah Bramono, Adhimukti T. Sampurna, Agassi Suseno Sutarjo

Journal of General - Procedural Dermatology and Venereology Indonesia

Skin cancer is a global health concern due to its growing incidence and high mortality rate. The most common therapeutic modalities in skin cancer include surgery, radiotherapy, and chemotherapy. However, those therapies do not specifically target cancer cells and may damage healthy tissues. Cancer induces immune response by releasing soluble antigens and danger signals caused by tumor cellular stress or death, while the immune system continuously monitor and control malignant proliferation through cancer immunoediting. Therefore, targeting this mechanism is a promising approach to manage cancer, especially those unresponsive to conventional therapies. Immunotherapy is a specific therapy that manipulates the immune …

Viral Infections In Pakistan: Prevalence, Factors Affecting Spread, And Recommendations For Control, Zehra Naseem, Maaha Ayub, Sharaf Ali Shah, Syed Asad Ali, Syed Hani Abidi

Medical College Documents

Pakistan is endemic to a number of viral infections, owing to its humid climate, topographical variation, soaring population, and lack of education and awareness. These viruses may have several different modes of transmission, including respiratory or airborne transmission, sexual transmission, blood-borne, fecal-oral transmission, vector-borne transmission, and transmission following an organ transplant. Although several different microorganisms are responsible for causing these infections, a few viruses are found more commonly in Pakistan and are primarily responsible for causing infections. In this study, we present a review of the most recent studies on different viruses, transmitted through various transmission routes, found commonly in …

Pathogenesis Of Tuberculosis: The 1930 Lübeck Disaster Revisited, Peter Donald, Stefan Kaufmann, Stephanie Thee, Anna Maria Mandalakas, Christoph Lange

Faculty, Staff and Students Publications

During the 1930 Lübeck Mycobacterium bovis bacille Calmette–Guérin (BCG) disaster, 251 neonates received three oral BCG doses accidentally contaminated by virulent Mycobacterium tuberculosis; 67 (26.7%) infants died of tuberculosis. BCG reversion to pathogenicity did not occur. Detailed post mortem examinations clarified contested aspects of tuberculosis pathogenesis. Gastrointestinal infection was seldom “silent” and did not cause typical primary pulmonary lesions. In 15 infants, primary pulmonary foci were found but these resulted from vaccine ingestion and aspiration and were not caused by gastrointestinal infection spreading to the lungs without trace of its journey, as claimed by prominent researchers such as Calmette …

Dual-Mode Tumor Imaging Using Probes That Are Responsive To Hypoxia-Induced Pathological Conditions, S A Amali S Subasinghe, Robia G Pautler, Md Abul Hassan Samee, Jason T Yustein, Matthew J Allen

Faculty, Staff and Students Publications

Hypoxia in solid tumors is associated with poor prognosis, increased aggressiveness, and strong resistance to therapeutics, making accurate monitoring of hypoxia important. Several imaging modalities have been used to study hypoxia, but each modality has inherent limitations. The use of a second modality can compensate for the limitations and validate the results of any single imaging modality. In this review, we describe dual-mode imaging systems for the detection of hypoxia that have been reported since the start of the 21st century. First, we provide a brief overview of the hallmarks of hypoxia used for imaging and the imaging modalities used …

Regulation Of Age-Associated Insulin Resistance By Mt1-Mmp-Mediated Cleavage Of Insulin Receptor, Xuanming Guo, Pallavi Asthana, Susma Gurung, Shuo Zhang, Sheung Kin Ken Wong, Samane Fallah, Chi Fung Willis Chow, Sijia Che, Lixiang Zhai, Zening Wang, Xin Ge, Zhixin Jiang, Jiayan Wu, Yijing Zhang, Xiaoyu Wu, Keyang Xu, Cheng Yuan Lin, Hiu Yee Kwan, Aiping Lyu, Zhongjun Zhou, Zhao-Xiang Bian, Hoi Leong Xavier Wong

Faculty, Staff and Student Publications

Insulin sensitivity progressively declines with age. Currently, the mechanism underlying age-associated insulin resistance remains unknown. Here, we identify membrane-bound matrix metalloproteinase 14 (MT1-MMP/MMP14) as a central regulator of insulin sensitivity during ageing. Ageing promotes MMP14 activation in insulin-sensitive tissues, which cleaves Insulin Receptor to suppress insulin signaling. MT1-MMP inhibition restores Insulin Receptor expression, improving insulin sensitivity in aged mice. The cleavage of Insulin Receptor by MT1-MMP also contributes to obesity-induced insulin resistance and inhibition of MT1-MMP activities normalizes metabolic dysfunctions in diabetic mouse models. Conversely, overexpression of MT1-MMP in the liver reduces the level of Insulin Receptor, impairing hepatic insulin …

Dartmouth College Ph.D Dissertations

Systemic sclerosis (SSc) is a rare autoimmune disease characterized by fibrosis of the skin and internal organs, vascular abnormalities, and autoantibody formation. The etiology of SSc is unknown, though the disease is thought to arise in genetically predisposed individuals after exposure to an environmental factor. There are few FDA approved disease modifying medications available to treat SSc.

The express aims of this dissertation are tripart. First, we aimed to validate a 3D tissue model known as the self-assembled skin equivalent (saSE) model. Second, we sought to describe the geographic distribution of SSc in a US Medicare population to better understand …

Expanding Anti-Cd38 Immunotherapy For Lymphoid Malignancies, Xu Wang, Xinfang Yu, Wei Li, Praveen Neeli, Ming Liu, Ling Li, Mingzhi Zhang, Xiaosheng Fang, Ken H Young, Yong Li

Faculty, Staff and Students Publications

BACKGROUND: Lymphoid neoplasms, including multiple myeloma (MM), non-Hodgkin lymphoma (NHL), and NK/T cell neoplasms, are a major cause of blood cancer morbidity and mortality. CD38 (cyclic ADP ribose hydrolase) is a transmembrane glycoprotein expressed on the surface of plasma cells and MM cells. The high expression of CD38 across MM and other lymphoid malignancies and its restricted expression in normal tissues make CD38 an attractive target for immunotherapy. CD38-targeting antibodies, like daratumumab, have been approved for the treatment of MM and tested against lymphoma and leukemia in multiple clinical trials.

METHODS: We generated chimeric antigen receptor (CAR) T cells targeting …

Gain-Of-Signal Assays For Probing Inhibition Of Sars-Cov-2 Mpro/3clpro In Living Cells, Seyed Arad Moghadasi, Morgan A Esler, Yuka Otsuka, Jordan T Becker, Sofia N Moraes, Constance B Anderson, Srinivas Chamakuri, Christopher Belica, Chloe Wick, Daniel A Harki, Damian W Young, Louis Scampavia, Timothy P Spicer, Ke Shi, Hideki Aihara, William L Brown, Reuben S Harris

Faculty, Staff and Students Publications

The main protease, Mpro, of SARS-CoV-2 is required to cleave the viral polyprotein into precise functional units for virus replication and pathogenesis. Here, we report quantitative reporters for Mpro function in living cells in which protease inhibition by genetic or chemical methods results in robust signal readouts by fluorescence (enhanced green fluorescent protein [eGFP]) or bioluminescence (firefly luciferase). These gain-of-signal systems are scalable to high-throughput platforms for quantitative discrimination between Mpro mutants and/or inhibitor potencies as evidenced by validation of several reported inhibitors. Additional utility is shown by single Mpro amino acid variants and structural information combining to demonstrate that …
