Case Study 6: Deconvoluting Hyperbilirubinemia-Differentiating Among Hepatotoxicity and Reversible Inhibition involving UGT1A1, MRP2, or perhaps OATP1B1 within Drug Advancement.
Glucocorticoids (GC) still represent an essential pillar of treatment in the phase of remission induction of vasculitides, which are often organ or life-threatening; however, they entail a significant potential for side effects. FHD-609 In the phase of remission maintenance prednisolone should be reduced to 7.5 mg/day or less. Whether a discontinuation can alway be achieved for any form of vasculitis without increasing relapse rates, is unclear. By the use of biologics, e.g. tocilizumab in giant cell arteritis (GCA), a fast tapering and discontinuation of GC seems to be more easily achievable compared to using a GC monotherapy regimen. Avacopan could in the future be an efficient agent to spare GC in the phase of remission induction in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), e.g. granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). Mepolizumab is a promising option to reduce the use of GC in eosinophilic granulomatosis with polyangiitis (EGPA).
Endocrine disorders are the result of insufficient or excessive hormonal production. The clinical course is long, and the manifestations are nonspecific due to the systemic effect of hormones across many organs and systems including the nervous system. This is a narrative review of the recent evidence of the diagnosis and treatment approach of these medical and neurological emergencies.

With the possible exception of diabetic ketoacidosis, hyperosmolar hyperglycemic state, and hypoglycemia, endocrinological emergencies are complex, uncommon yet life-threatening conditions with protean and often nonspecific early clinical signs. They frequently are the first manifestation of the endocrine derangement. The systemic effects of hormones extend to the nervous system and as such, these conditions can present with neurological complications manifested, in most cases, by a diffuse dysfunction of the brain in the form of encephalopathy, delirium, seizures, and coma; or specific and peculiar syndromes such as hemiccomplication most often improves with the correction of the metabolic derangement and their acuity and severity require admission to the intensive care unit.
The LARS score is an internationally well-accepted questionnaire to assess low anterior resection syndrome, but currently there is no formally validated Italian version. The purpose of this study was to test the reliability and validity of the Italian version among Italian patients submitted to sphincter-sparing surgery for rectal cancer.

The English version of the LARS score was translated into Italian following the forward-and-back translation process. A total of 147 patients filled out our version. Among them, 40 patients answered the questionnaire twice for the test-retest reliability phase. The validity of the LARS score was tested using convergent and discriminant validity indicators by correlating the EORTC QLQ-C30 and QLQ-CR29 questionnaires. The LARS score capability to differentiate groups of patients with different demographic or clinical features was also assessed.

The test-retest reliability was excellent in 87.5% of patients, remained in the same LARS category in both tests. The convergent validity phase showed a relevant relationship of the LARS score with the EORTC domains, which was significant for 7 of 15 EORTC QLQ-C30 subscales, and for 14 of 29 EORTC QLQ-CR29 subscales. The LARS score was able to discriminate patients who received radiotherapy (p = 0.0026), TME vs. PME (p = 0.0060), tumour site at < 10 cm from the anal verge (p = 0.0030) and history of protective stoma (p < 0.0001).

The Italian version of the LARS score is a valid and reliable tool for measuring LARS in Italian patients after SSS for rectal cancer.

NO can be synthetized by three different isoforms of the enzyme NO synthase neuronal (nNOS), typical of neurons, endothelial and inducible. The aim of this study was to assess nNOS expression in human corpus callosum (CC) astrocytes, and its relationship with the hypoxia duration. Autoptic samples of CC from adult human subjects have been processed with immunohistochemistry and immunofluorescence using antibodies anti-nNOS and anti-glial fibrillary acidic protein (GFAP), the astrocyte marker. Results demonstrated for the first time the presence of nNOS-immunopositive astrocytes in the human CC. In particular, nNOS-positive astrocytes were absent in subjects deceased after a short hypoxia; their number and labeling intensity, however, increased with hypoxia prolongation. Neuronal NOS immunopositivity of CC astrocytes seems thus related to the hypoxia duration and the consequent brain damage.This work aims at isolating a fungal source for L-asparaginase production to be applied in reducing acrylamide levels in coffee beans at non-cytotoxic levels. An L-asparaginase-producing fungus was isolated from an agricultural soil sample and identified as Penicillium crustosum NMKA 511. A maximum L-asparaginase activity of 19.10 U/mL was obtained by the above-mentioned fungus when grown under optimum conditions (i.e. 16.96 g/L sucrose as carbon source, 1.92 g/L peptone as nitrogen source, pH 7.7 and 33.5 °C). Further, the produced L-asparaginase was purified and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) showed that P. crustosum L-asparaginase was a heterodimer enzyme with molecular weights of approximately 41.3 and 44.4 kDa. Also, the purified P. crustosum L-asparaginase was specific towards L-asparagine and showed negligible and no effects towards L-glutamine and D-asparagine, respectively. Additionally, the purified L-asparaginase reduced the acrylamide levels by 80.7% and 75.8% in light and dark roasted coffee beans, respectively. The amount of L-asparaginase used to reduce acrylamide was considered safe when cell viability reached 94.6%.
