Unusual False-Negative Serum Human Chorionic Gonadotropin Detected By Qualitative Immunoassay: A Case Report Of Two Iraqi Women, Bashar J. Kadem, Falah H.O Al-Khikani

Journal of Medicine in Scientific Research

Human chorionic gonadotropin (hCG) is a human pregnancy hormone that plays a crucial role in the promotion, maintenance, and establishment of pregnancy. Measurement of hCG in early pregnancy is the first and most common test. Blood is considered to have more concentration of hCG than urine, so early detection of pregnancy test is more advised in serum than urine, but this study showed two Iraqi pregnant women with false-negative hCG result in the blood, whereas it was positive in urine, with persisting pregnancy symptoms. This study is considered the first report regarding this finding. In spite of hCG in serum …

Histopathology Of Celiac Disease. Position Statements Of The Italian Group Of Gastrointestinal Pathologists (Gipad-Siapec), Carolina Ciacci

Translational Medicine @ UniSa

Celiac Disease (CeD) is an immunemediated inflammatory disorder of the small intestine, affecting genetically susceptible individuals when exposed to gluten. Small intestinal biopsy interpretation has been the "gold standard" for celiac disease (CeD) for over 50 years. Despite today's availability of sensitive and specific serological tests, the histopathological features from mucosal biopsy play a key role in diagnosing when CeD is suspected. Such a diagnostic approach requires a multidisciplinary team to optimize both tissue sampling and interpretation via the interaction between the pathologist and the gastroenterologist. Pathologists of the Italian Group of Gastrointestinal Pathology (GIPAD-SIAPEC), together with a member (TR) …

The Many Faces Of Covid-19: Organizing Pneumonia (Op) Pattern Hrct Features, Gaetano Rea

Translational Medicine @ UniSa

Histone Demethylase Phf8 Drives Neuroendocrine Prostate Cancer Progression By Epigenetically Upregulating Foxa2., Qiuli Liu, Jian Pang, Lin-Ang Wang, Zhuowei Huang, Jing Xu, Xingxia Yang, Qiubo Xie, Yiqiang Huang, Tang Tang, Dali Tong, Gaolei Liu, Luofu Wang, Dianzheng Zhang, Qiang Ma, Hualiang Xiao, Weihua Lan, Jun Qin, Jun Jiang

PCOM Scholarly Works

Neuroendocrine prostate cancer (NEPC) is a more aggressive subtype of castration-resistant prostate cancer (CRPC). Although it is well established that PHF8 can enhance prostate cancer cell proliferation, whether PHF8 is involved in prostate cancer initiation and progression is relatively unclear. By comparing the transgenic adenocarcinoma of the mouse prostate (TRAMP) mice with or without Phf8 knockout, we systemically examined the role of PHF8 in prostate cancer development. We found that PHF8 plays a minimum role in initiation and progression of adenocarcinoma. However, PHF8 is essential for NEPC because not only is PHF8 highly expressed in NEPC but also animals without …

Angiotensin Inhibition And Gastrointestinal Bleeding Prevention In Patients With Left Ventricular Assist Devices, Phillip A. Weeks

The VAD Journal

Gastrointestinal bleeding remains a common complication in advanced heart failure patients following implantation of continuous-flow left ventricular assist devices. While the cause is likely multifactorial, development of arterial venous malformations in the gastrointestinal mucosa are a key factor. Inhibition of angiotensin II activity has been postulated to disrupt the signaling that promotes angiogenesis in these patients. We aim to review the theoretical basis for angiotensin receptor blockade, which has been proposed and explore the published evidence regarding this therapy and gastrointestinal bleeding in LVAD patients.

Microglia Prevent Beta-Amyloid Plaque Formation In The Early Stage Of An Alzheimer's Disease Mouse Model With Suppression Of Glymphatic Clearance, Weixi Feng, Yanli Zhang, Ze Wang, Hanrong Xu, Ting Wu, Charles Marshall, Junying Gao, Ming Xiao

Physical Therapy Faculty Publications

BACKGROUND: Soluble beta-amyloid (Aβ) can be cleared from the brain through various mechanisms including enzymatic degradation, glial cell phagocytosis, transport across the blood-brain barrier, and glymphatic clearance. However, the relative contribution of each clearance system and their compensatory effects in delaying the pathological process of Alzheimer's disease (AD) are currently unknown.

METHODS: Fluorescent trace, immunofluorescence, and Western blot analyses were performed to compare glymphatic clearance ability and Aβ accumulation among 3-month-old APP695/PS1-dE9 transgenic (APP/PS1) mice, wild-type mice, aquaporin 4 knock out (AQP4^−/−) mice, and AQP4^−/−/APP/PS1 mice. The consequence of selectively eliminating microglial cells, or downregulating apolipoprotein …

Comparison Study: Trauma-Focused Cognitive Behavioral Therapy And Acceptance And Commitment Therapy For Trauma, Colleen Marie Kirsch Hiltz White

Dissertations

There is a need for more evidenced based treatments for adolescents with trauma related disorders. Currently, Trauma Focused Cognitive Behavioral Therapy (TF CBT) is the gold standard, but clients and clinician need the ability to choose between effective treatments. This study completed a direct comparison between six weeks of treatment in Acceptance and Commitment Therapy for Trauma and TF CBT via telehealth during the COVID-19 pandemic. Treatments were measured using the Clinician Administered PTSD Scale and the Child PTSD Symptom Scale. Both treatments were found to be effective in reducing trauma related symptoms in two 12-year-old females.

The Social Value Of Zero Balancing, David Laden

Journal of Transformative Touch

Does Zero Balancing have a social value? Does it in some way contribute to the betterment of society? Does it really have the capacity to make the world a better place? These are questions I started asking myself years ago when I was going through a period of soul searching - investigating my own feelings of powerlessness - feelings of not doing enough in the larger sphere of “making the world a better place”.

Post-Influenza Vaccine Subdeltoid Bursitis, Marenda Jenkins, David Rupp, Lynne J. Goebel

Internal Medicine

A 61-year-old female presented three months following an influenza vaccination with ongoing pain since the injection and was diagnosed by MRI with subdeltoid bursitis. The patient received a short course of prednisone and several months of physical therapy before returning to pain-free function. The primary reason for injection-related subdeltoid bursitis is improper administration. It is a preventable issue, and improved training of healthcare workers on proper vaccine administration may decrease its occurrence.

There has been one previous report of a cohort of patients with variants in Chromodomain Helicase DNA-binding 3 (CHD3), now recognized as Snijders Blok-Campeau syndrome. However, with only three previously-reported patients with variants outside the ATPase/helicase domain, it was unclear if variants outside of this domain caused a clinically similar phenotype. We have analyzed 24 new patients with CHD3 variants, including nine outside the ATPase/helicase domain. All patients were detected with unbiased molecular genetic methods. There is not a significant difference in the clinical or facial features of patients with variants in or outside this domain. These additional patients further …

Mcgee, Victor P. Pedro, Jennifer Kerkhof, Alan Stuart, Peter J. Ainsworth, Hanxin Lin, Michael Volodarsky, Catherine Meg Mclachlin, Bekim Sadikovic

Paediatrics Publications

Poly-ADP-ribose-polymerase inhibitor (PARPi) treatment is indicated for advanced-stage ovarian tumors with BRCA1/2 deficiency. The “BRCAness” status is thought to be attributed to a tumor phenotype associated with a specific epigenomic DNA methylation profile. Here, we examined the diagnostic impact of combined BRCA1/2 sequence, copy number, and promoter DNA methylation analysis, and evaluated whether genomic DNA methylation patterns can predict the BRCAness in ovarian tumors. DNA sequencing of 172 human tissue samples of advanced-stage ovarian adenocarcinoma identified 36 samples with a clinically significant tier 1/2 sequence variants (point mutations and in/dels) and 9 samples with a CNV causing a loss of …

Methods: We conducted a multi-center prospective study in which an activity tracker was utilized to measure the steps taken by patients after delivery. The primary outcome was steps taken after vaginal or cesarean delivery. Secondary outcomes was factors affecting ambulation (e.g pain/satisfaction with pain management and mode of delivery).

Results: Data from 50 postpartum patients were analyzed. Vaginal delivery patients took more cumulative …

Management Of Early Rectal Cancer: Current Practice And Future, Bhavani Mothe, Hasnain Zafar, Shakil Ahmed

Section of General Surgery

Early rectal cancer management includes tumour stages TiS, T1 and some selected T2 lesions that undergo appropriate clinical pre-operatie evaluation. Local excision of these lesions with acceptable recurrence rate can be achieved through various transanal endoscopic techniques like transanal endoscopic microsurgery (TEM) and transanal minimal invasive surgery (TAMIS) that are superior to simple transanal excision (TAE). The current literature review was planned to present the oncological evaluation of local excision in the context of available evidence. An overview of perioperative adjuvant therapies employed along with local excision is presented, with an update on the latest trials.

Untargeted Longitudinal Analysis Of A Wellness Cohort Identifies Markers Of Metastatic Cancer Years Prior To Diagnosis., Andrew T Magis, Noa Rappaport, Matthew P Conomos, Gilbert S Omenn, Jennifer C Lovejoy, Leroy Hood, Nathan D Price

Articles, Abstracts, and Reports

We analyzed 1196 proteins in longitudinal plasma samples from participants in a commercial wellness program, including samples collected pre-diagnosis from ten cancer patients and 69 controls. For three individuals ultimately diagnosed with metastatic breast, lung, or pancreatic cancer, CEACAM5 was a persistent longitudinal outlier as early as 26.5 months pre-diagnosis. CALCA, a biomarker for medullary thyroid cancer, was hypersecreted in metastatic pancreatic cancer at least 16.5 months pre-diagnosis. ERBB2 levels spiked in metastatic breast cancer between 10.0 and 4.0 months pre-diagnosis. Our results support the value of deep phenotyping seemingly healthy individuals in prospectively inferring disease transitions.
