A new digital health tool for the telemonitoring of patients with scleroderma during iloprost administration: a feasibility and acceptability study.

OBJECTIVE: To assess the feasibility of a new device for telemonitoring vital parameters during iloprost infusion. MATERIALS AND METHODS: In a pilot study, patients with systemic sclerosis received iloprost infusion while being telemonitored with Umana T1 Heart Monitor, within the hospital, under the supervision of family/community nurses and rheumatologists. Patients were administered a questionnaire to obtain information on satisfaction, practicability, and compliance with the new monitoring device. RESULTS: Data recorded by the device for blood pressure, heart rate, and oximetry were concordant with those registered directly by nurses. Most patients found the device useful and thought it could be used at home, even while working. CONCLUSIONS: Umana Heart Monitor T1 could be a valuable aid in at-home iloprost therapy in patients with systemic sclerosis.

The cytokine storm and thyroid hormone changes in COVID-19.

BACKGROUND: COVID-19 is now a worldwide pandemic. Among the many extra-pulmonary manifestations of COVID-19, recent evidence suggested a possible occurrence of thyroid dysfunction. PURPOSE: The Aim of the present review is to summarize available studies regarding thyroid function alterations in patients with COVID-19 and to overview the possible physio-pathological explanations. CONCLUSIONS: The repercussions of the thyroid of COVID-19 seem to be related, in part, with the occurrence of a "cytokine storm" that would, in turn, induce a "non-thyroidal illness". Some specific cytokines and chemokines appear to have a direct role on the hypothalamus-pituitary-thyroid axis. On the other hand, some authors have observed an increased incidence of a destructive thyroiditis, either subacute or painless, in patients with COVID-19. The hypothesis of a direct infection of the thyroid by SARS-Cov-2 stems from the observation that its receptor, ACE2, is strongly expressed in thyroid tissue. Lastly, it is highly probable that some pharmaceutical agents largely used for the treatment of COVID-19 can act as confounding factors in the laboratory evaluation of thyroid function parameters.

The new generation PFAS C6O4 does not produce adverse effects on thyroid cells in vitro.

PURPOSE: Per- and poly-fluoroalkyl-substances (PFASs) are synthetic compounds that raised concern due to their potential adverse effects on human health. Long-chain PFAS were banned by government rules in many states, and thus, new emerging PFAS were recently introduced as substitutes. Among these, Perfluoro{acetic acid, 2-[(5-methoxy-1,3-dioxolan-4-yl)oxy]}, ammonium salt (C6O4) was recently introduced to produce a range of food contact articles and literature data about this compound are scanty. The aim of this study was to evaluate the in vitro effects of exposure to C6O4, compared with PFOA and PFOS on thyroid cells. METHODS: FRTL5 rat-thyroid cell lines and normal human thyroid cells (NHT) were incubated with increasing concentrations of C6O4 for 24, 48, 72, and 144 h to assess cell viability by WST-1. Cell viability was confirmed by AnnexinV/PI staining. Long-chain PFAS (PFOA and PFOS) were used at same concentrations as positive controls. The proliferation of cells exposed to C6O4, PFOA, and PFOS was measured by staining with crystal violet and evaluation of optical density after incubation with SDS. Changes in ROS production by FRTL5 and NHT after exposure to C6O4 at short (10, 20, and 30 min) and long-time points (24 h) were evaluated by cytofluorimetry. RESULTS: C6O4 exposure did not modify FRTL5 and NHT cell viability at any concentration and/or time points with no induction of necrosis/apoptosis. At difference, PFOS exposure reduced cell viability of FRTL5 while and NHT, while PFOA only in FRTL5. FRTL5 and NHT cell proliferation was reduced by incubation with by PFOA and PFOS, but not with C6O4. ROS production by NHT and FRTL5 cells was not modified after C6O4 exposure, at any time/concentration tested. CONCLUSIONS: The present in vitro study constitutes the first evaluation of the potential adverse effects of the new emerging PFAS C6O4 in cultured rat and human thyroid cells, suggesting its safety for thyroid cells in vitro.

SETD2 and histone H3 lysine 36 methylation deficiency in advanced systemic mastocytosis.

The molecular basis of advanced systemic mastocytosis (SM) is not fully understood and despite novel therapies the prognosis remains dismal. Exome sequencing of an index-patient with mast cell leukemia (MCL) uncovered biallelic loss-of-function mutations in the SETD2 histone methyltransferase gene. Copy-neutral loss-of-heterozygosity at 3p21.3 (where SETD2 maps) was subsequently found in SM patients and prompted us to undertake an in-depth analysis of SETD2 copy number, mutation status, transcript expression and methylation levels, as well as functional studies in the HMC-1 cell line and in a validation cohort of 57 additional cases with SM, including MCL, aggressive SM and indolent SM. Reduced or no SETD2 protein expression-and consequently, H3K36 trimethylation-was found in all cases and inversely correlated with disease aggressiveness. Proteasome inhibition rescued SETD2 expression and H3K36 trimethylation and resulted in marked accumulation of ubiquitinated SETD2 in SETD2-deficient patients but not in patients with near-normal SETD2 expression. Bortezomib and, to a lesser extent, AZD1775 alone or in combination with midostaurin induced apoptosis and reduced clonogenic growth of HMC-1 cells and of neoplastic mast cells from advanced SM patients. Our findings may have implications for prognostication of SM patients and for the development of improved treatment approaches in advanced SM.

Risk profile in women with stroke: role of plasma fibrinogen.

In 96 women with ischemic stroke, (mean age 77.9 +/- 7.4, S.D., years, body mass index, BMI = 23.7 +/- 3.91, we assessed the presence of risk factors for atherosclerosis, particularly of hyperfibrinogenemia. A control group of 96 women without relevant diseases, namely neoplasms, cardiovascular and inflammatory diseases, well matched for age and BMI was also studied. Subjects with stroke show higher values of systolic and diastolic blood pressure, total serum cholesterol, fibrinogen, hematocrit and more frequent habit of cigarette smoking. Levels of HDL-cholesterol, triglyceridemia and glycemia do not differ between the 2 groups. In stroke group fibrinogen is positively correlated with systolic and diastolic blood pressure and triglyceridemia. These findings confirm the presence of a risk profile for stroke, in which hypertension plays the most relevant role. The weight of fibrinogen in pathogenesis of stroke is likely to be related to the presence of other risk factors.

[Neuropsychologic symptoms of primary hyperparathyroidism in the elderly. Report of a clinical case]. / Sintomatologia neuropsichica da iperparatiroidismo primitivo nell'anziano. Descrizione di un caso clinico.

Primary hyperparathyroidism is a not uncommon disease in the elderly. A prevalence of 3% for women and 1% for men is reported in subjects aged 65 years and over. Routine serum calcium determination and parathyroid hormone radioimmuno-assay allow to make an early diagnosis in still asymptomatic subjects. In the elderly the clinical features of the disease are often aspecific presenting with psychiatric and/or neuromuscular and/or cardiovascular disorders. This report refers to a 75 year-old woman admitted to our Department with a suspicion of senile dementia. She was affected by loss of memory, hallucinations, nausea, loss of appetite, mild polydipsia and polyuria. The patient was dependent in one activity of daily living (Index of Independence in Activities of Daily Living, ADL) and partially dependent in instrumental activities of daily living (Instrumental Activities of Daily Living Scale, IADL). The Short Portable Mental Status Questionnaire (SPMSQ) and the Geriatric Depression Scale (GDS) showed mild mental impairment and mild depression. Routine biochemical screening revealed a significant hypercalcemia. Parathormon assay and parathyroid scintigram were performed to confirm the diagnosis of primary hyperparathyroidism. After treatment of dehydratation and hypercalcemia, parathyroidectomy was performed: a single parathyroid adenoma was found and removed. On discharge the patient was lucid and able to carry out all ADLs and IADLs.

[Comparative evaluation of the efficacy of naproxen sodium and ibuprofen in the treatment of primary dysmenorrhea]. / Valutazione comparativa dell'efficacia del naprossene sodico e dell'ibuprofene nel trattamento della dismenorrea primaria.

Efficacy of Naproxen sodium and Ibuprofen have been compared in the treatment of primary dysmenorrhoea on 67 women aged between 13 and 20 casually divided into two groups. No statistically significant difference has been noticed in the remission of symptomatology between the two groups at therapeutic dosage, although Naproxen sodium has a longer plasmatic half-life than Ibuprofen.
