To review the epidemiology, presentation, diagnosis, and management of head and neck paragangliomas.

A literature review of english language papers with focus on most current literature.

Paragangliomas (PGLs) are a group of neuroendocrine tumors that arise in the parasympathetic or sympathetic ganglia. Head and neck PGLs (HNPGLs) comprise 65% to 70% of all PGLs and account for 0.6% of all head and neck cancers. The majority of HNPGLs are benign, and 6% to 19% of all HNPGLs develop metastasis outside the tumor site and significantly compromise survival. PGLs can have a familial etiology with germline sequence variations in different susceptibility genes, with the gene encoding succinate dehydrogenase being the most common sequence variation, or they can arise from somatic sequence variations or fusion genes. Workup includes biochemical testing to rule out secretory components, although it is rare in HNPGLs. In addition, imaging modalities, such as computed tomography and magnetic resonance imaging, help in monitoring in surgical planning. Functional imaging with DOTATATE-positron emission tomography, 18F-fluorodeoxyglucose, or 18F-fluorohydroxyphenylalanine may be necessary to rule out sites of metastases. The management of HNPGLs is complex depending on pathology, location, and aggressiveness of the tumor. Treatment ranges from observation to resection to systemic treatment. Similarly, the prognosis ranges from a normal life expectancy to a 5-year survival of 11.8% in patients with distant metastasis.

Our review is a comprehensive summary of the incidence, mortality, pathogenesis, presentation, workup and management of HNPGLs.
Our review is a comprehensive summary of the incidence, mortality, pathogenesis, presentation, workup and management of HNPGLs.The effects of temperature on breathing pattern and oxygen consumption are being investigated in juvenile tortoises and compared to adults, in order to understand physiological adjustments of the respiratory system as related to body size, especially regarding the energetic expenditure associated with growth. We analyzed the breathing pattern and oxygen consumption of juvenile and adult red-footed tortoises (Chelonoidis carbonarius, Cryptodira Testudinidae). The animals (N = 9; body mass ranging from 0.03 Kg to 2.5 Kg) were exposed to normoxic-normocarbic conditions using open respirometry in order to determine the breathing pattern and oxygen consumption in three different temperatures (15, 25, 35 °C). The obtained results showed intermittent breathing pattern in all tested temperatures in juveniles and adults. Tidal volume was not affected by changes in temperature, while breathing frequency increased significantly with increasing temperature, leading to a significant increment in minute ventilation between 15 and 35 °C. Mass specific oxygen consumption increased significantly with temperature and juveniles showed greater values when compared to adults. The alterations in the ventilatory response to temperature changes occurred in order to maintain the oxygen supply with increased metabolic activity. The differences between juveniles and adults in breathing frequency lead to juveniles needing a lower ventilation rate to perform gas exchange while extracting more oxygen. While these differences might be attributed to a greater metabolic expenditure during development, scaling effects on respiratory variables might be the main contributors to the found differences.PPARγ1 and FOXO1 are the key transcription factors that regulate insulin sensitivity. We previously found that a small ubiquitin-related modifier of PPARγ1 at K77 (SUMOylation) favored endothelial insulin resistance (IR) induced by high fat/high glucose (HF/HG) administration. click here However, whether and how the crosstalk between SUMOylated PPARγ1 and FOXO1 would mediate the development of the endothelial IR and dysfunction remains unclear. Here, we emphasize how PPARγ1-K77 SUMOylation would interact with FOXO1 and participate in the development of the endothelial IR and dysfunction. Our results show that the combination of HF/HG and PPARγ1-K77 SUMOylation exhibits a synergistic deteriorative effect on the endothelial IR and dysfunction, presenting decreased NO levels and elevated ET-1 levels, weakened PI3K/Akt/eNOS signaling, and impaired endothelium-dependent vasodilation function. The further researches reveal that PPARγ1-K77 SUMOylation readily interacts with FOXO1, and FOXO1 occupies the PPAR response element (PPRE) which is supposed to be occupied by PPARγ, thus resulting in the decrease of PPARγ1 transcription activity and the mitigation of the PI3K/Akt signaling. Moreover, the mitigation of the PI3K/Akt signaling promotes in turn the accumulation of FOXO1 in the nucleus where FOXO1 interacts with the SUMOylated PPARγ1, thus exerting a positive feedback effect on IR pathogenesis. The findings uncover a novel association between PPARγ1-K77 SUMOylation and FOXO1, which contributes to our understanding of the pathogenesis of endothelial IR and dysfunction and provides novel pharmacological targets for diabetic angiopathy.
Most studies consider either medications ordered or filled, but not both. Medication underuse based on filling data cannot necessarily be ascribed to patient nonadherence. Using both data sources, we quantified primary medication adherence in a cohort of prevalent systemic lupus erythematosus (SLE) pregnancies.

We identified 419 pregnancies in Kaiser Permanente Northern California in patients with prevalent SLE from 2011 to 2020. We calculated the number of physician-initiated orders or pharmacy-initiated reorders during pregnancy and a comparable 9-month window the year before (prepregnancy) and the proportion of orders ever filled and filled within 30 days for hydroxychloroquine (HCQ), azathioprine, and corticosteroids. For pregnancies without an order or reorder, we identified the proportion with previous prescription fills overlapping into the respective study period.

New orders for lupus medications were usually filled. HCQ was prescribed most often (45.8% pregnancies) and usually filled (89.7% in prepregnancy, 93.2% during pregnancy). The majority filled within 30 days (80.5% prepregnancy, 83.3% pregnancy). Some pregnancies without new HCQ orders had continuous refills from prior orders; 53% of 2011-2015 pregnancies either had a new order or fill coverage from a previous period, compared to 63.2% of pregnancies delivering in 2016-2019. Corticosteroid fill frequencies were 90.6% in prepregnancy and 83.6% during pregnancy. Fewer patients used azathioprine; however, most new orders were filled (94.3% prepregnancy, 91.7% pregnancy). For azathioprine and corticosteroids, fill rates were modestly higher in prepregnancy compared to pregnancy.

We observed that patients have high adherence to filling new orders for lupus medications, such as HCQ and azathioprine, in pregnancy.

Besides surgery, chemotherapy using temozolomide, carmustine or lomustine is the main pillar of therapy. However, therapy success is limited and prognosis still is very poor. One restraining factor is drug resistance caused by drug transporters of the ATP-binding cassette family, e.g. ABCB1 and ABCG2, located at the blood-brain barrier and on tumor cells. The active efflux of xenobiotics including drugs, e.g. temozolomide, leads to low intracellular drug concentrations and subsequently insufficient anti-tumor effects. Nevertheless, the role of efflux transporters in GBM is controversially discussed. In the present study, we analyzed the role of ABCB1 and ABCG2 in GBM cells showing that ABCB1, but marginally ABCG2, is relevant. Applying a CRISPR/Cas9-derived ABCB1 knockout, the response to temozolomide was significantly augmented demonstrated by decreased cell number (p < 0.001) and proliferation rate (p = 0.04), while apoptosis was increased (p = 0.04). For carmustine, a decrease of cells in G1-phase was detected pointing to cell cycle arrest in the ABCB1 knockout (p = 0.006). For lomustine, however, loss of ABCB1 did not alter the response to the treatment. Overall, this study shows that ABCB1 is involved in the active transport of temozolomide out of the tumor cells diminishing the response to temozolomide. Interestingly, loss of ABCB1 also affected the response to the lipophilic drug carmustine. These findings show that ABCB1 is not only relevant at the blood-brain barrier, but also in the tumor cells diminishing success of chemotherapy.Allergic rhinitis (AR) is a series of reactions to allergen mediated by immunoglobulin E (IgE) and is one of the most common allergic diseases that affects children. Traditional Chinese Medicine, due to its diverse regulatory functions, may offer new strategies for AR therapy. Huanggui Tongqiao Granules (HTG) is a Chinese formula consisting of twelve herbs and has long been prescribed for patients with AR. The aim of this study is to determine the possible targets and action mechanisms of HTG for the AR treatment. SymMap database and TMNP algorithm were employed to show that interferon-gamma (IFN-gamma), acting as a molecular link between immunity and neural circuits, is the involved key target. The enrichment of immune and virus-related signaling pathways indicated the neuroimmunomodulatory potential of HTG. Then, AR mouse model was established by ovalbumin (OVA) challenge and was used to verify the therapeutic effects of HTG in vivo. HTG significantly relieved AR symptoms and nasal mucosal inflammation, reduced OVA-specific IgE levels and balanced IFN-gamma/IL-4 ratio. Moreover, transcriptional profile based on clinical data presented that blood cell-specific IFN-gamma co-expressed gene module (BIM) was underexpressed in AR patients, further validating the potential of IFN-gamma as target for AR. Collectively, these findings suggest that HTG could be a promising candidate drug for AR.Metabolic (dysfunction)-associated fatty liver disease (MAFLD) is characterized by the accumulation of lipids in the liver (steatosis). In predisposed individuals, liver steatosis can progress to inflammation, fibrosis, cirrhosis, and hepatocellular carcinoma. The pathogenesis of MAFLD is complex and incompletely understood, involving various steatogenic, pro-inflammatory, and fibrogenic processes. Hyperactivation of the innate immune system through hepatic toll-like receptors (TLRs) contributes to the pathogenesis of MAFLD. Products of intestinal microbiota and danger signals from damaged hepatocytes constitute key ligands of TLRs that promote MAFLD. Most TLRs promote development and progression of MAFLD by induction of pro-inflammatory and pro-fibrogenic cytokines. Several nutraceutical and therapeutic agents improve MAFLD partly through the inhibition of hepatic TLRs. Herein, we review the available literature on hepatic TLR expression and signaling; crosstalk between gut microbiota and hepatic TLRs; and the contribution of TLRs to the pathogenesis of MAFLD. We also highlight implications for therapeutic approaches for MAFLD based on modulation of TLR signaling.
