PROBLEM: Health-risk behaviors contribute to the leading causes of morbidity and mortality among youth and adults in the United States. In addition, significant health disparities exist among demographic subgroups of youth defined by sex, race/ethnicity, and grade in school and between sexual minority and nonsexual minority youth. Population-based data on the most important health-related behaviors at the national, state, and local levels can be used to help monitor the effectiveness of public health interventions designed to protect and promote the health of youth at the national, state, and local levels...

The objective of this study was to investigate the factors underlying the development of metabolic syndrome (MetS) in HIV-infected patients. Two hundred and sixty-six clinical cases were selected for a retrospective study. The sample was classified using the Adult Treatment Panel III guidelines and the identification of risk or protective factors associated with MetS evaluated via multivariate logistic or multinomial regressions. HIV-infected individuals diagnosed with MetS tend to be older, overweight, or obese (85% have a BMI ≥ 25), with a waist circumference > 90 cm (96...

Intestinal spirochetosis (IS) is an infestation defined by the presence of spirochetes on the surface of the colonic mucosa. The implicated organisms can be Brachyspira aalborgi or Brachyspira pilosicoli . We present the case of a 66-year-old man with a past medical history of diabetes mellitus, hypertension, morbid obesity, and gastroesophageal reflux. The patient was sent to the gastroenterology clinic for a screening colonoscopy due to a prior history of colonic polyps. The patient was completely asymptomatic as he denies any abdominal pain, diarrhea, melena, or hematochezia...

Obstructive sleep apnea (OSA) is defined by repetitive collapse of the upper airway during sleep leading to transient hypoxemia and arousals from sleep. Surges in sympathetic activity, repeated oxygen desaturation, and sleep fragmentation can lead to cardiovascular (eg, myocardial infarction) and neurocognitive (eg, excessive daytime sleepiness) consequences. Emerging data suggest that OSA is common in people living with human immunodeficiency virus (PLWH) and that traditional risk factors for OSA, such as obesity, are not highly predictive of OSA in PLWH...

Cellular therapies are emerging as a novel treatment strategy for diabetes. Thus, the induction of endogenous islet regeneration in situ represents a feasible goal for diabetes therapy. Umbilical cord blood (UCB)-derived hematopoietic progenitor cells (HPC) isolated by high aldehyde dehydrogenase activity (ALDH<sup>hi</sup>) have previously been shown to reduce hyperglycemia after intrapancreatic (iPan) transplantation into streptozotocin (STZ)-treated non-obese diabetic (NOD) severe combined immunodeficient (SCID) mice...

Prevalence and risk factors for hepatic steatosis (HS) in the human immunodeficiency virus (HIV)-positive population of western countries are controversially discussed and potentially confounded by coinfection with viral hepatitis. Significant HS (more than 10% of hepatocytes) can be accurately assessed using controlled attenuation parameter (CAP) determination. Aim of this study was to assess prevalence and factors associated with significant HS in HIV monoinfected patients.A total of 364 HIV-infected patients (289 monoinfected) were included in this prospective, cross-sectional study...

The JAK-STAT signal transduction pathway is responsible for mediating signals of over fifty cytokines, growth factors and hormones. Signaling through the JAK-STAT pathway is regulated on multiple levels, including intramolecular regulation by the JAK pseudokinase domain, and intermolecular regulation by a host of regulatory proteins. The advent of accessible genomic tools have provided a wealth of information on disease-associated mutations in the JAK-STAT pathway and its regulatory components. The vast number of these mutations in diseases ranging from immunodeficiencies and obesity to many cancers highlight the importance of correct regulation of JAK-STAT signaling for biological processes such as hematopoiesis, regulation of the immune system, metabolism, and growth...

PURPOSE: The point prevalence of underweight status and obesity in primary immunodeficiency disease (PID) is unknown, despite the described associations between PID and weight loss and failure to thrive. The goal of this study is to estimate the prevalence of underweight status and obesity in PID patients and to investigate the associations between abnormal body weight and complications of PID. METHODS: Using the US Immunodeficiency Network (USIDNET), we performed a retrospective analysis of 653 pediatric (age 2 to 20 years) and 514 adult (age > 20) patient records with information on patient body mass index (BMI)...

Partial hepatectomy is a versatile and reproducible method to study liver regeneration and the effect of cell based therapeutics in various pathological conditions. Partial hepatectomy also facilitates the increased engraftment and proliferation of transplanted cells by accelerating neovascularization and cell migration towards the liver. Here, we describe a simple protocol for performing 30% hepatectomy and transplantation of cells in the spleen of a non-obese diabetic/severe combined immunodeficient NOD.SCID (NOD...

The three cell lines, designated as gastric cancer (GC)1401, GC1415 and GC1436 were derived from peritoneal effusions from patients with gastric adenocarcinoma. Cell lines were established in tissue culture and in immunodeficient, non-obese diabetic/severe combined immunodeficiency (NOD/SCID) mice. All cell lines were cultured in Dulbecco's modified Eagle's medium supplemented with 5% fetal bovine serum. These cell lines were grown as an adherent monolayer with doubling time ranging between 25 h (GC1436 cell line) and 30-34 h (GC1401 and GC1415, respectively)...

In contrast to well-established hierarchical concepts of tumor stem cells, leukemia-initiating cells in B-cell precursor acute lymphoblastic leukemia have not yet been phenotypically identified. Different subpopulations as defined by surface markers have shown equal abilities to reconstitute leukemia upon transplantation onto immunodeficient mice. Using a non-obese diabetes/severe combined immunodeficiency human acute lymphoblastic leukemia mouse model and cell cycle analysis annotating cells to distinct cycle phases, we have functionally characterized leukemia-initiating cells and found that cells in all cell cycle stages are able to reconstitute leukemia in vivo, with early cycling cells (G1blow population) exhibiting the highest leukemia-initiating potential...

Tolerogenic DCs (tolDCs) are being researched as a promising intervention strategy also in autoimmune diseases including type 1 diabetes (T1D). T1D is a T-cell-mediated, organ-specific disease with several well-defined and rather specific autoantigens, i.e., proinsulin, insulin, glutamic acid decarboxylase 65 (GAD65), that have been used in animal as well as human intervention trials in attempts to achieve a more efficient, specific immunotherapy. In this study, we have tested tolerogenic DCs for their effectiveness to prevent adoptive transfer of diabetes by diabetogenic splenocytes into non-obese diabetes (NOD)-severe combined immunodeficiency (NOD-SCID) recipients...

Nutrition is an integral component of medical care for people living with human immunodeficiency virus (HIV)/autoimmune deficiency syndrome (AIDS) (PLWHA). The Academy of Nutrition and Dietetics supports integration of medical nutrition therapy into routine care for this population. Fewer PLWHA experience wasting and undernutrition, while the prevalence of obesity and other chronic diseases has increased significantly. Improved understanding of HIV infection's impact on metabolism and chronic inflammation has only increased the complexity of managing chronic HIV infection...

Chronic hepatitis B (CHB) is one of the major causes of morbidity and mortality worldwide. Currently, clinically approved nucleos(t)ide analogs (NAs) are very efficient in reducing the load of hepatitis B virus (HBV) with minimum side effects. However, the long-term administration of antiviral drugs promotes HBV for potential drug resistance. To overcome this problem, combination therapies are administered, but HBV progressively altered mutations remain a threat. Therefore, optimally designed NAs are urgently needed to treat drug-resistant HBV...

Intrauterine adhesions (IUA) are associated with the loss of stem cells in the endometrium. Menstrual blood‑derived stem cells (MenSCs) can be isolated from the menstrual blood and differentiated into endometrial cells. To check the transplantation feasibility of MenSCs for the treatment of severe IUA, MenSCs were isolated from menstrual blood, cultured in Dulbecco's modified Eagle's medium (DMEM), identified by immunocytochemistry and flow cytometry, differentiated into endometrial cells in vitro, and finally transplanted into the axillary subcutaneous tissue of non‑obese diabetic/severe combined immunodeficiency (NOD‑SCID) mice to create endometrial tissue...

We recently demonstrated that obinutuzumab (GA101), a novel glycoengineered type II CD20 Ab compared to rituximab (RTX) mediates significantly enhanced antibody-dependent cell cytotoxicity (ADCC) in vitro and increased overall survival in a Burkitt lymphoma (BL) xenograft non-obese diabetic severe combined immunodeficiency gamma (NSG) model. In this study we compared the phosphoproteomic changes by pathway analysis following obinutuzumab vs RTX against RTX-sensitive (Raji) and -resistant BL (Raji4RH). Phosphoproteomic analyses were performed by mass-spectrometry (MS)-based label-free quantitative phosphoproteomic profiling...
