The evolution of the Pharmacovigilance department in the pharmaceutical industry: results of an Italian national survey.

Background: Pharmacovigilance (PV) is the science and activities relating to the detection, assessment, understanding, and prevention of adverse effects or any other medicine/vaccine-related problem. Since its inception in the 1960s, PV has undergone continuous evolution, progressing from a basic level mainly focused on the collection and analysis of cases in its earliest years to a complex system regulated by rigorous standards and laws with modern PV. In recent years, PV has faced the challenge of adapting to rapid scientific advancements, the complexity of the pharma industry, and the digital revolution.

Predictors of mastectomy in breast cancer patients with complete remission of primary tumor after neoadjuvant therapy: A retrospective study.

Introduction: Neoadjuvant therapy (NAT) should increase the rate of breast-conserving surgery (BCS) in non-metastatic breast cancer (BC) patients, especially in those achieving tumor shrinkage. Still, the conversion from a pre-planned mastectomy to BCS in patients responding to NAT is not a widespread standard. We aimed to identify factors influencing surgical choices in this setting.

Molecular Typing and Resistance Profile of Isolates during the COVID-19 Pandemic: Findings from the "EPIRADIOCLINF" Project.

Due to the COVID-19 pandemic, there has been a shift in focus towards controlling the spread of SARS-CoV-2, which has resulted in the neglect of traditional programs aimed at preventing healthcare-associated infections and combating antimicrobial resistance. The present work aims to characterize the colonization or infection with of COVID-19 patients and to identify any clonality between different isolates. Specifically, data and resistance profiles of isolates were prospectively collected from patients recruited by the EPIRADIOCLINF project.

Convergent evolution of dim light vision in owls and deep-diving whales.

Animals with enhanced dim-light sensitivity are at higher risk of light-induced retinal degeneration when exposed to bright light conditions. This trade-off is mediated by the rod photoreceptor sensory protein, rhodopsin (RHO), and its toxic vitamin A chromophore by-product, all-trans retinal. Rod arrestin (Arr-1) binds to RHO and promotes sequestration of excess all-trans retinal, which has recently been suggested as a protective mechanism against photoreceptor cell death.

One-Stage Implant-Based Breast Reconstruction With Polyurethane-Coated Device: Standardized Assessment of Outcomes.

Background: Nipple-sparing mastectomies (NSMs) and implant-based breast reconstructions have evolved from 2-stage reconstructions with tissue expansion and implant exchange to direct-to-implant procedures. In this study, we tested safety and efficacy of polyurethane-based implants according to standard assessment tools.

Objectives: This study aimed to test safety and feasibility of polyurethane-coated implants with standardized assessment employing internationally acknowledged evaluation criteria.

Thoraco-dorsal artery perforator flap for totally autologous primary breast reconstruction. Assessment of feasibility with standard reporting scales.

This study reports on feasibility and applicability of totally autologous primary breast reconstructions based on TDAP flaps using a standard set of internationally approved reporting scales. We reviewed 15 cases in patients with a good donor area in the back not suitable for implant or free flaps reconstructions. Complications according to Clavien Dindo were: 1 Grade 1 (seroma in the back).

Adaptation of Antarctic Icefish Vision to Extreme Environments.

Extreme environments, such as Antarctic habitats, present major challenges for many biological processes. Antarctic icefishes (Crynotothenioidea) represent a compelling system to investigate the molecular basis of adaptation to cold temperatures. Here, we explore how the sub-zero habitats of Antarctic icefishes have impacted rhodopsin (RH1) function, the temperature-sensitive dim-light visual pigment found in rod photoreceptors.

Evolutionary pathways to SARS-CoV-2 resistance are opened and closed by epistasis acting on ACE2.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infects a broader range of mammalian species than previously predicted, binding a diversity of angiotensin converting enzyme 2 (ACE2) orthologs despite extensive sequence divergence. Within this sequence degeneracy, we identify a rare sequence combination capable of conferring SARS-CoV-2 resistance. We demonstrate that this sequence was likely unattainable during human evolution due to deleterious effects on ACE2 carboxypeptidase activity, which has vasodilatory and cardioprotective functions in vivo.

Dual expression and anatomy lines allow simultaneous visualization of gene expression and anatomy.

Studying the developmental genetics of plant organs requires following gene expression in specific tissues. To facilitate this, we have developed dual expression anatomy lines, which incorporate a red plasma membrane marker alongside a fluorescent reporter for a gene of interest in the same vector. Here, we adapted the GreenGate cloning vectors to create two destination vectors showing strong marking of cell membranes in either the whole root or specifically in the lateral roots.

In vivo characterization of emerging SARS-CoV-2 variant infectivity and human antibody escape potential.

As severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spreads, variants with enhanced virulence and transmissibility have emerged. Although in vitro systems allow rapid characterization, they do not fully recapitulate the dynamic interaction of virions and neutralizing antibodies in the airway. Here, we demonstrate that the N501Y variant permits respiratory infection in unmodified mice.

Lopinavir/Ritonavir and Darunavir/Cobicistat in Hospitalized COVID-19 Patients: Findings From the Multicenter Italian CORIST Study.

Protease inhibitors have been considered as possible therapeutic agents for COVID-19 patients. To describe the association between lopinavir/ritonavir (LPV/r) or darunavir/cobicistat (DRV/c) use and in-hospital mortality in COVID-19 patients. Multicenter observational study of COVID-19 patients admitted in 33 Italian hospitals.

Adjunctive IgM-enriched immunoglobulin therapy with a personalised dose based on serum IgM-titres versus standard dose in the treatment of septic shock: a randomised controlled trial (IgM-fat trial).

Introduction: In patients with septic shock, low levels of circulating immunoglobulins are common and their kinetics appear to be related to clinical outcome. The pivotal role of immunoglobulins in the host immune response to infection suggests that additional therapy with polyclonal intravenous immunoglobulins may be a promising option in patients with septic shock. Immunoglobulin preparations enriched with the IgM component have largely been used in sepsis, mostly at standard dosages (250 mg/kg per day), regardless of clinical severity and without any dose adjustment based on immunoglobulin serum titres or other biomarkers.

Recreated Ancestral Opsin Associated with Marine to Freshwater Croaker Invasion Reveals Kinetic and Spectral Adaptation.

Rhodopsin, the light-sensitive visual pigment expressed in rod photoreceptors, is specialized for vision in dim-light environments. Aquatic environments are particularly challenging for vision due to the spectrally dependent attenuation of light, which can differ greatly in marine and freshwater systems. Among fish lineages that have successfully colonized freshwater habitats from ancestrally marine environments, croakers are known as highly visual benthic predators.

ACE2 and TMPRSS2 are expressed on the human ocular surface, suggesting susceptibility to SARS-CoV-2 infection.

Purpose: Conjunctival signs and symptoms are observed in a subset of patients with COVID-19, and SARS-CoV-2 has been detected in tears, raising concerns regarding the eye both as a portal of entry and carrier of the virus. The purpose of this study was to determine whether ocular surface cells possess the key factors required for cellular susceptibility to SARS-CoV-2 entry/infection.

Methods: We analyzed human post-mortem eyes as well as surgical specimens for the expression of ACE2 (the receptor for SARS-CoV-2) and TMPRSS2, a cell surface-associated protease that facilitates viral entry following binding of the viral spike protein to ACE2.

Adaptation of the master antioxidant response connects metabolism, lifespan and feather development pathways in birds.

Birds (Aves) display high metabolic rates and oxygen consumption relative to mammals, increasing reactive oxygen species (ROS) formation. Although excess ROS reduces lifespan by causing extensive cellular dysfunction and damage, birds are remarkably long-lived. We address this paradox by identifying the constitutive activation of the NRF2 master antioxidant response in Neoaves (~95% of bird species), providing an adaptive mechanism capable of counterbalancing high ROS levels.

[Giant parathyroid adenoma: a rare cause of severe hypercalcemia].

We report the case of a 37-year-old woman that developed severe hypercalcemia due to a parathyroid gland mass. After the initial medical treatment, only a minimal reduction of calcemia was observed and her clinical condition worsened; thus, she required continuous renal replacement therapy (CRRT) that resulted in the normalization of calcium serum level. She then underwent a left thyroid lobectomy with exeresis of the associated parathyroid glands; the histological diagnosis revealed a giant parathyroid adenoma (GPA).

Renal resistive index: a new reversible tool for the early diagnosis and evaluation of organ perfusion in critically ill patients: a case report.

Background: We reported a case of early detection of peripheral hypoperfusion trough the evaluation of a new index in intensive care: Renal Doppler Resistive Index (RRI).

Case Presentation: We admitted a 76-year-old man who underwent ileostomy and hernioplasty because of an intestinal occlusion due to obstructive strangulated right inguinal hernia. The post-operative period was characterised by hemodynamic instability and he needed an invasive hemodynamic monitoring, administration of vasopressors and continuous renal replacement therapy (CRRT).

Diagnostic surveillance by Candida albicans germ tube antibody in intensive care unit patients.

Background: The diagnosis of Invasive Candidiasis (IC) presents serious problems, mainly associated with the absence of pathognomonic symptoms of the disease and the difficulty of isolating the fungus in blood culture. Candida albicans germ tube antibody (CAGTA) provides a rapid and simple test for diagnosis of IC. The aim of this study was to evaluate the diagnostic role of the CAGTA in the monitoring of critically-ill patients at risk of developing IC.

Functional trade-offs and environmental variation shaped ancient trajectories in the evolution of dim-light vision.

Trade-offs between protein stability and activity can restrict access to evolutionary trajectories, but widespread epistasis may facilitate indirect routes to adaptation. This may be enhanced by natural environmental variation, but in multicellular organisms this process is poorly understood. We investigated a paradoxical trajectory taken during the evolution of tetrapod dim-light vision, where in the rod visual pigment rhodopsin, E122 was fixed 350 million years ago, a residue associated with increased active-state (MII) stability but greatly diminished rod photosensitivity.

Functional Shifts in Bat Dim-Light Visual Pigment Are Associated with Differing Echolocation Abilities and Reveal Molecular Adaptation to Photic-Limited Environments.

Bats are excellent models for studying the molecular basis of sensory adaptation. In Chiroptera, a sensory trade-off has been proposed between the visual and auditory systems, though the extent of this association has yet to be fully examined. To investigate whether variation in visual performance is associated with echolocation, we experimentally assayed the dim-light visual pigment rhodopsin from bat species with differing echolocation abilities.

Convergent selection pressures drive the evolution of rhodopsin kinetics at high altitudes via nonparallel mechanisms.

Convergent evolution in response to similar selective pressures is a well-known phenomenon in evolutionary biology. Less well understood is how selection drives convergence in protein function, and the underlying mechanisms by which this can be achieved. Here, we investigate functional convergence in the visual system of two distantly related lineages of high-altitude adapted Andean and Himalayan catfishes.

Accelerated Evolution and Functional Divergence of the Dim Light Visual Pigment Accompanies Cichlid Colonization of Central America.

Cichlids encompass one of the most diverse groups of fishes in South and Central America, and show extensive variation in life history, morphology, and colouration. While studies of visual system evolution in cichlids have focussed largely on the African rift lake species flocks, Neotropical cichlids offer a unique opportunity to investigate visual system evolution at broader temporal and geographic scales. South American cichlid colonization of Central America has likely promoted accelerated rates of morphological evolution in Central American lineages as they encountered reduced competition, renewed ecological opportunity, and novel aquatic habitats.
