Investigating coping and stigma in people living with HIV through narrative medicine in the Italian multicentre non-interventional study DIAMANTE.

Antiretroviral therapy (ART) significantly reduced Human Immunodeficiency Virus (HIV) morbidity and mortality; nevertheless, stigma still characterises the living with this condition. This study explored patients' coping experience by integrating narrative medicine (NM) in a non-interventional clinical trial. From June 2018 to September 2020 the study involved 18 centres across Italy; enrolled patients were both D/C/F/TAF naïve and previously ART-treated. Narratives were collected at enrolment (V1) and last visit (V4) and then independently analysed by three NM specialist researchers through content analysis. One-hundred and fourteen patients completed both V1 and V4 narratives. Supportive relationships with clinicians and undetectable viral load facilitated coping. Conversely, lack of disclosure of HIV-positive status, HIV metaphors, and unwillingness to narrate the life before the diagnosis indicated internalised stigma. This is the first non-interventional study to include narratives as patient reported outcomes (PROs). Improving HIV awareness and reducing the sense of guilt experienced by patients helps to overcome stigma and foster coping.

Epileptologists telling their experiences caring for patients with epilepsy.

OBJECTIVE: This research was focused on expert professionals in epilepsy care to understand their points of view on the care pathway and their living relationships with patients. METHODS: Researchers prepared a semi-structured parallel chart and distributed it online among 21 Italian centres of care. Each health professional was prompted to write five narratives on cases of patients with epilepsy, subsequently analysed through narrative medicine methods. Next, a consensus meeting was held, to individualise an action plan based on the narratives. RESULTS: Ninety-one parallel charts were collected from 25 epileptologists, who had a mean age of 50 years; their narratives concerned patients with a mean age of 37 years, with different types of epilepsy (53 % drug-resistant; 31 % unemployed). The limitations in the daily life of people with epilepsy (57 %), employment (42 %), caregiver burden (51 %), and the universal prevalence of fear were the primary topics that emerged. Attentive and reassuring care relationships were found to be the main element of coping (21 %). A new multi-factorial classification of epilepsies, integrating clinical with social and legal risk factors, was the main agreed action to face the issues identified. CONCLUSIONS: The narrative medicine approach supplied a broader scenario of living with epilepsy, including the family and social impact and possible effects on the choices for care pathways. The epileptologists showed a strong motivation to care for patients with epilepsy and deep involvement in the care relationships; the use of parallel chart demonstrated to be an effective tool to preserve their wellbeing.

Listening to the neurological teams for multiple sclerosis: the SMART project.

OBJECTIVE: Aim of the research was to define the quality of life of Italian neurologists and nurses' professional caring for multiple sclerosis, to understand their living the clinical practice and identify possible signals of compassion fatigue. MATERIAL AND METHODS: One hundred five neurologists and nurses from 30 Italian multiple sclerosis centres were involved in an online quali-quantitative survey on the organization of care, combined with the Satisfaction and Compassion Fatigue Test and a collection of narratives. Descriptive statistics of the quantitative data were integrated with the results obtained by the narrative medicine methods of analysis. RESULTS: Most of the practitioners were neurologists, 46 average years old, 69% women, 43% part time dedicated to multiple sclerosis. An increased number of patients in the last 3 years were referred in 29 centres. Differences were found between neurologists and nurses. Physicians showed higher risks of burnout, reporting intensive working paces, lack of medical personnel, and anxiety caused by the precarious employment conditions. Nurses appeared more satisfied, although the reference to the lack of spaces, and the cross professional roles risk of compassion fatigue. Both positive and negative relationships of care were depicted as influencing the professional quality of life. CONCLUSION: The interviewed neurological teams need to limit the risk of compassion fatigue, which appeared from the first years of the career. The prevalence of the risk among neurologists suggests more awareness among scientific societies and health care managers on the risk for this category, as first step to prevent it.

Minimal impact of lenvatinib (Lenvima®) on muscle mass in advanced hepatocellular carcinoma and implications for treatment duration. Two cases from the REFLECT study.

OBJECTIVE: Two case reports of advanced unresectable hepatocellular carcinoma (HCC) treated with lenvatinib (Lenvima®) are presented; the drug's effect on muscle loss and duration of treatment are discussed. PATIENTS AND METHODS: Between November 2014 and December 2017, at the Fondazione Policlinico A. Gemelli IRCCS, Rome, Italy, two male patients with advanced HCC enrolled in the lenvatinib arm of the REFLECT trial received the drug over 24 cycles (almost 2 years). We reviewed the clinical charts from baseline, when lenvatinib was started, through 24 months of treatment. The changes in the skeletal mass area (SMA), as assessed by computed tomography (CT) at the third lumbar level (L3), between baseline and month 24 into treatment were recorded. RESULTS: Case 1: SMA decreased by 2.8 cm2 between baseline and month 24 (134 cm2 vs. 131.2 cm2), with a muscle loss of 2.13%. Case 2: SMA decreased by 13 cm2 between baseline and month 24 (133 cm2 vs. 120 cm2), with a muscle loss of 10.83%. CONCLUSIONS: The disease remained stable for over 2.5 years in both patients. A minimal loss of muscle mass was noted at 24 months of treatment. The minimum effect on muscle loss may be correlated with the positive clinical response and the drug's low toxicity. Our findings may help to elucidate the effect of lenvatinib on muscle mass and inform the development of the targeted nutritional support for HCC patients.

Critical analysis of major and ancillary features of LI-RADS v2018 in the differentiation of small (≤ 2 cm) hepatocellular carcinoma from dysplastic nodules with gadobenate dimeglumine-enhanced magnetic resonance imaging.

OBJECTIVE: To evaluate the performance of major features, ancillary features, and categories of Liver Imaging Reporting and Data System (LI-RADS) version 2018 at magnetic resonance (MR) imaging in the differentiation of small hepatocellular carcinoma (HCC) from dysplastic nodules (DNs). PATIENTS AND METHODS: This retrospective study included cirrhotic patients with pathologically proven untreated HCCs and DNs (≤ 2 cm) and liver MR imaging performed with gadobenate dimeglumine contrast agent within 3 months before pathological analysis, between 2015 and 2018. 37 patients with 43 observations (17 HCCs and 26 DNs) met the inclusion criteria. Two radiologists assessed major and ancillary imaging features for each liver observation and assigned a LI-RADS v2018 category in consensus. Estimates of diagnostic performance of major features, ancillary features, and LI-RADS categories were assessed based on their sensitivity, specificity, positive (PPV), and negative predictive values (NPV). RESULTS: Major features (nonrim arterial phase hyperenhancement, nonperipheral "washout", and enhancing "capsule") had a sensitivity of 94.1%, 88.2%, and 41.2%, and a specificity of 57.7%, 42.3%, and 88.5% for HCC, respectively. Ancillary features (hepatobiliary phase hypointensity, mild-moderate T2 hyperintensity, restricted diffusion, and fat in the lesion more than adjacent liver) had a sensitivity of 94.1%, 64.7%, 58.8%, and 11.8%, and a specificity of 26.9%, 61.5%, 65.4%, and 76.9% for HCC, respectively. The LR-5 category (determined by using major features only vs. the combination of major and ancillary features) had a sensitivity of 88.2% at both evaluations and a specificity of 76.9% and 80.8% for HCC, respectively. The combination of LR-4, LR-5 categories (determined by using major features only vs. the combination of major and ancillary features) had a sensitivity of 94.1% at both interpretations and a specificity of 65.4% and 26.9% for HCC, respectively. The use of ancillary features modified LI-RADS category in 25.6% of observations (11/43), predominantly upgraded from LR-3 to LR4 (10/11), increasing the proportion of low-grade DNs and high-grade DNs categorized as LR-4 (from 15.4% to 61.5% and from 7.7% to 46.1%, respectively). CONCLUSIONS: The added value of ancillary features in combination with major features is limited for the non-invasive diagnosis of small HCC; however, their use modifies the final category in a substantial proportion of observations from LR-3 to LR-4, thus allowing possible changes in the management of patients at risk for HCC.

Imaging assessment of portal venous system: pictorial essay of normal anatomy, anatomic variants and congenital anomalies.

The purpose of this pictorial essay is to describe anatomic variants and congenital anomalies of portal venous system and related liver parenchymal alterations. The imaging findings of some of these entities have been previously described in other articles, however this work encompasses all congenital anomalies of portal venous system with attention to their features on various imaging modalities; in particular we illustrated with detailed pictures all the main portal vein variants, congenital extra- and intra-hepatic porto-systemic venous shunts and portal vein aneurysm. Variants of portal branches and intrahepatic portosystemic shunts are quite uncommon, however, when present, they should be recognized before performing surgery or interventional procedures. Congenital absence of the portal vein is an important finding as the complete loss of portal perfusion predisposes the liver to focal or diffuse hyperplastic or dysplastic changes. Portal vein aneurysm is a rare clinical entity that can affect intra- and extra-hepatic portal branches; although usually asymptomatic, thrombosis can occur. Awareness of congenital variants of portal venous system among radiologists should allow a more confident diagnosis and permit an accurate planning of surgical procedures and percutaneous interventions; identification of portal system anomalies also suggest an accurate evaluation of associated hepatic parenchymal anomalies such as nodular regenerative hyperplasia, focal nodular hyperplasia (FNH), and adenomas with high risk of malignant transformation.

A novel missense mutation (C84R) in a patient with type II vitamin d-dependent rickets.

A 7-year-old boy with severe rickets that by clinical analysis was diagnosed as affected by type II vitamin D-dependent rickets, was evaluated for mutations in the vitamin D receptor gene (VDR). The molecular analysis showed a homozygous state for a novel missense mutation (C84R) in a highly conserved nucleotide in the second Zn finger of the DNA binding domain.

Nuclear factor-erythroid 2 (NF-E2) expression in normal and malignant megakaryocytopoiesis.

Although the transcription factor nuclear factor-erythroid 2 (NF-E2) is known to be functionally linked to the megakaryocytic lineage, little is known about its role in malignant megakaryocytes. We used real-time RT-PCR and Western blotting to investigate expression of NF-E2 and its partner, MafG, in CD34-derived normal (five cases) and malignant megakaryocytes from essential thrombocythemia (ET) patients (eight cases) and in megakaryoblastic cell lines. We also quantitated the mRNA of the thromboxane synthase (TXS) gene, which is directly regulated by NF-E2. Although real-time RT-PCR showed that both a and f NF-E2 isoforms were significantly reduced with respect to the normal counterpart both in ET megakaryocytes and in cell lines (P < or = 0.01), western blotting revealed decreased NF-E2 protein expression only in the latter. However, both the NF-E2a/MafG mRNA ratio (P < or = 0.01) and TXS (P< or = 0.01) mRNA expression were significantly reduced in megakaryocytes from ET patients and cell lines with respect to healthy subjects. These two findings provide strong indirect evidence of altered activity of the a isoform of NF-E2 in malignant megakaryocytes, raising the possibility that NF-E2 could play a role in megakaryocyte transformation.

A novel splicing defect (IVS6+1G>T) in a patient with pseudovitamin D deficiency rickets.

A 15-month-old boy with severe rickets, that by clinical analysis was diagnosed as affected by hereditary pseudovitamin D deficiency rickets (PDDR), was evaluated for mutations in the 25OHD3 1alpha-hydroxylase gene. Molecular analysis showed a double heterozygous state for a novel splicing mutation in the invariant dinucleotide of the donor site of IVS6 and a 7 nucleotide insertion in the exon 8, which is common in different ethnical backgrounds.

hMAF, a small human transcription factor that heterodimerizes specifically with Nrf1 and Nrf2.

A 1.6-kilobase pair full-length cDNA encoding a transcription factor homologous to the Maf family of proteins was isolated by screening a K562 cDNA library with the NFE2 tandem repeat probe derived from the globin locus control region. The protein, which was designated hMAF, contains a basic DNA binding domain and an extended leucine zipper but lacks any recognizable activation domain. Expressed in vitro, the hMAF protein is able to homodimerize in solution and band-shift the NFE2 tandem repeat probe. In addition to homodimers, hMAF can also form high affinity heterodimers with two members of the NFE2/CNC-bZip family (Nrf1 and Nrf2) but not with a third family member, p45-NFE2. Although hMAF/hMAF homodimers and hMAF/Nrf1 and hMAF/Nrf2 heterodimers bind to the same NFE2 site, they exert functionally opposite effects on the activity of a linked gamma-globin gene. In fact, whereas all hMAF/CNC-bZip heterodimers stimulate the activity of a gamma-promoter reporter construct in K562 cells, the association into homodimers that is induced by overexpressing hMAF inhibits the activity of the same construct. Thus variations in the expression of hMAF may account for the modulation in the activity of the genes that bear NFE2 recognition sites.

A 4-week, double-blind, parallel-group study to compare the gastrointestinal effects of meloxicam 7.5 mg, meloxicam 15 mg, piroxicam 20 mg and placebo by means of faecal blood loss, endoscopy and symptom evaluation in healthy volunteers.

Meloxicam is a new non-steroidal anti-inflammatory drug (NSAID) which preferentially inhibits cyclooxygenase-2 (COX-2) over cyclooxygenase-1 (COX-1). Gastrointestinal (GI) tolerability of meloxicam 7.5 and 15 mg vs piroxicam 20 mg was evaluated in a 4-week, double-blind, parallel group, placebo-controlled study in 51 healthy male volunteers, using a combination of oesphago-gastro-duodenal endoscopy, faecal blood loss measurement and symptom evaluation. Analysis of covariance found no significant difference in faecal blood loss between the groups. However, significantly higher bleeding was found with piroxicam 20 mg compared with placebo using a Student's t-test on the weighted means. Endoscopy score were significantly higher with piroxicam than with meloxicam 7.5 mg or placebo (P < 0.01). A significant difference from baseline was observed in the meloxicam 15 mg and piroxicam groups (P < 0.05), but not in the meloxicam 7.5 mg and placebo groups. Six piroxicam-treated volunteers were withdrawn following a poor endoscopic score, but no such withdrawals occurred in the meloxicam and placebo groups (P < 0.01). Meloxicam 7.5 mg caused less GI damage compared with piroxicam 20 when administered to healthy young volunteers for 28 days; a possible dose dependency effect in GI tolerability was also suggested for meloxicam 7.5 and 15 mg, in relation to endoscopic findings.

Isolation of a differentially regulated splicing isoform of human NF-E2.

The transcription factor NF-E2 (nuclear factor erythroid 2), interacting via DNA motifs within regulatory regions of several hematopoietic genes, is thought to mediate the enhancer activity of the globin locus control regions. By screening a human fetal liver cDNA library with probes derived from mouse NF-E2, we have isolated a splicing variant of the NF-E2 gene (fNF-E2) that differs in the 5' untranslated region from the previously reported cDNA (aNF-E2). The fNF-E2 isoform is transcribed from an alternative promoter located in the 3' end of the first intron and joined by alternative splicing to the second and third exons, which are shared by both RNA isoforms. Although the two forms produce the same protein, they are expressed in different ratios during development. fNF-E2 is more abundant in the fetal liver and less abundant in the adult bone marrow compared to the previously described form. Their distribution apparently follows the differential expression of fetal and adult hemoglobins.

A comparison of the local tolerability, safety and efficacy of meloxicam and piroxicam suppositories in patients with osteoarthritis: a single-blind, randomized, multicentre study.

The local tolerability, safety and efficacy of meloxicam 15 mg suppositories were compared with piroxicam 20 mg suppositories over a 3-week period in a single-blind, randomized study in patients with osteoarthritis. Patients were randomized 2:1 to receive meloxicam (n = 216) or piroxicam (n = 109). More than 90% of patients and investigators assessed local tolerability of both treatments as good or very good (primary endpoint). There was no significant difference between the groups. Global efficacy was reported by approximately 80% of patients in both groups to be good or very good. Pain on movement and at rest and joint mobility showed statistically significant improvements compared with baseline with both meloxicam and piroxicam; there were no statistically significant differences between treatment groups. Piroxicam and meloxicam suppositories were equally well tolerated, with no serious adverse events recorded in either treatment group. Local adverse events occurred in 11.9% of patients receiving piroxicam and 6.9% of those receiving meloxicam. Overall, gastrointestinal adverse events were the most frequent of all 11.9% of piroxicam-treated patients). In both groups, about 90% of global tolerability assessments were classified, by the investigator and the patient, as either very good or good. In conclusion, meloxicam 15 mg suppositories showed excellent local tolerability accompanied by good safety and efficacy in osteoarthritis, which was comparable to that of an established non-steroidal anti-inflammatory drug (NSAID) administered by the rectal route, and to that previously observed with oral formulations of meloxicam 15 mg.

A novel pharmacological approach for paraquat poisoning in rat and A549 cell line using ambroxol, a lung surfactant synthesis inducer.

Paraquat (PQ) is a widely used herbicide that causes acute adult respiratory distress syndrome (ARDS) and chronic lung damage (diffuse fibrosis). One of the earliest biochemical effects induced by PQ is damage to type II pneumocytes with consequent depletion of surfactant. With the aim of counteracting the toxic effects of PQ, a series of investigations were performed into the possible protective effect of the drug ambroxol, which induces the synthesis of surfactant in lung alveolar type II cells. The number of survivors and survival time of rats treated ip with 35 mg PQ/kg was significantly increased by 3 days of ambroxol pretreatment and by ambroxol treatment 30 min or 2 hr after PQ. Total phospholipid content in lung and bronchoalveolar lavage fluid (BALF) was significantly reduced 30 hr after treatment with PQ alone. The association of ambroxol with PQ significantly antagonized this reduction. In BALF the ratio between palmitic acid and stearic acid concentrations was significantly lower in animals treated with PQ alone but was returned to normal by the association with ambroxol. The cell line A549, exposed in vitro to PQ concentrations from 0.5 x 10(-4) to 2 x 10(-3) M, showed a significant dose-dependent loss of viability. Cells pretreated with ambroxol (10 mg/ml) were more resistant to PQ and their viability started to decrease significantly only from a PQ concentration of 0.8 x 10(-3) M. Membrane microviscosity was measured on the same cells. Cells treated with PQ alone showed a reduction of membrane microviscosity, which was significantly counteracted by ambroxol pretreatment. The curves of modification of membrane microviscosity of cells treated with PQ and with ambroxol plus PQ paralleled those of cell viability, indicating that the stimulation of surfactant synthesis in vitro may be a prerequisite for counteracting some of the early effects of PQ.

Alterations of the endoalveolar surfactant after surgery with extracorporeal circulation.

In 10 patients who required extracorporeal circulation (ECC) during surgery, we studied the damage induced by surgery to the pulmonary surfactant and the effectiveness of ambroxol in preventing changes in the phospholipid pool. There were 5 control patients and 5 patients who were given 1 g/day of ambroxol on the 4 days prior to and the 4 days after surgery. To follow changes in phospholipid concentrations, bronchoalveolar lavage (BAL) was performed before surgery and 24 h and 8 days after ECC. Phospholipids were assayed in the BAL liquid by two-dimensional thin-layer chromatography. There were marked decreases in total phosphorus and quantitative alterations of individual phospholipid species in the surfactant of the control group, but not in the patients treated with ambroxol.
