Age- and gender-related differences in the evolution of psychological and cognitive status after the lockdown for the COVID-19 outbreak: a follow-up study

Neurological Sciences - Individuals experienced psychological symptoms in response to quarantine for the COVID-19 pandemic. Therefore, we aimed to investigate the possible effect of age...     

Determination of 1-phenyl-2-propanone (P2P) by HS-GC/MS in a material sold as “wet amphetamine”

In this paper, we describe the approach to the characterization of an unusual material seized by the judicial authority, near Brescia City in Northern Italy. Usual analyses such as thin-layer chromatography, gas chromatography (GC)–flame ionization detection, and GC/mass spectrometry (MS) did not show the presence of drugs of abuse, in particular amphetamine-like compounds. The major solid component was identified as cornstarch; then taking into account the strong aromatic scent of the seized material; a preliminary experiment for volatile organic compounds was carried out by headspace (HS)-GC/MS. This analysis tentatively evidenced the presence of 1-phenyl-2-propanone (P2P), an amphetamine precursor. Therefore, we developed and optimized a new analytical method for determination of P2P in seized materials by HS-GC/MS. We also synthesized P2P, with the permission of the Ministry of Health, to have it as reference standard, because of its being illegal and the difficulty in obtaining it. This case had some analogies with the cases referred to as “wet amphetamine” by the judicial authority, in which amphetamines are sold mixed with P2P. The possible use of the material could be the production of tablets made of cornstarch with an aromatic scent similar to that of amphetamines to deceive consumers and to sell them as a drug of abuse.     

Glassy cell carcinoma of the endometrium: a case report and review of the literature

Glassy cell carcinomas are composed of malignant cells showing a "ground glass" cytoplasm, distinct cell membranes, and large nuclei with prominent nucleoli. To our knowledge, only 12 cases of glassy cell endometrial carcinomas (EGCC) have been reported until now. A 63-year-old patient complaining of irregular vaginal bleeding underwent hysteroscopy-guided biopsy revealing a well-differentiated endometrial endometrioid adenocarcinoma. The patient underwent left salpingo-oophorectomy, total abdominal hysterectomy, and pelvic lymphadenectomy. The final diagnosis was FIGO stage IB poorly differentiated endometrial adenosquamous carcinoma with > 90% of glassy tumor cells. The patient is alive, with no evidence of disease for 69 months after diagnosis. We describe an additional case of EGCC and review the data of the literature, emphasizing the need to strictly define the criteria for the diagnosis and the potential usefulness of assessing biologic parameters for the prognostic characterization of this rare entity.     

Safety of humanized monoclonal antibodies against IL-5 in asthma: focus on reslizumab

Introduction: Reslizumab, a humanized mAb against IL-5, reduces the number of eosinophils in the blood and lungs. Based on efficacy and safety data from pivotal RCTs, reslizumab had been approved for use as an add-on maintenance treatment of severe asthma with an eosinophilic phenotype in adults who have a history of exacerbations despite receiving their current asthma medicines.

Areas covered: Current literature on reslizumab has been reviewed with a specific focus on its safety profile in the treatment of severe asthma.

Expert opinion: Large pivotal and supportive trials reinforce the view that reslizumab is well tolerated, with an acceptable safety profile in patients exposed for longer than 2 years. However, no or few data concerning safety in special populations such as smokers, those with immune- and cellular senescence, patients with comorbidities and those receiving multi-drug treatments are available as yet. Furthermore, we need to fully elucidate some fundamental issues such as the risk of anaphylaxis and the long-term risk-benefit ratio of the impact of depletion of eosinophils and the potential risk of malignancies induced by a treatment with this anti-IL-5 agent.
