Object-oriented Programming Laws for Annotated Java Programs
Object-oriented programming laws have been proposed in the context of
languages that are not combined with a behavioral interface specification
language (BISL). The strong dependence between source-code and interface
specifications may cause a number of difficulties when transforming programs.
In this paper we introduce a set of programming laws for object-oriented
languages like Java combined with the Java Modeling Language (JML). The set of
laws deals with object-oriented features taking into account their
specifications. Some laws deal only with features of the specification
language. These laws constitute a set of small transformations for the
development of more elaborate ones like refactorings
Requirements of the authorized examinator physician (AME) for class II: interpretative doubts and suggestions
The purpose of this document is to clarify the requirements
that a doctor must have for carrying
out the Authorized Examiner (AME) activity for
class II workers.
We have consulted the normative sources that indicate
the requisite that the authorized physicians
must possess and subsequently we have compared
the norms, the European Union regulations
and the national ones issued by the National Civil
Aviation Body (ENAC), as well as the guidelines
indicated by the EASA.
Finally, Authors give suggestions that can be given
to ENAC regarding the issue of the authorization
as AME examiner for class II workers
Chronotype is differentially associated with lifetime mood and panic-agoraphobic spectrum symptoms in patients with bipolar disorder and healthy controls.
Objective. Although the association between chronotype and mood disorders has been con-
sistently reported, conversely, attempts to measure the association between chronotype and
anxiety symptoms have generated inconsistent results. We aimed at evaluating whether chron-
otype (assessed through subjective and objective measures) is associated with lifetime mood and
panic-agoraphobic spectrum symptoms in healthy controls (HCs) and in patients with bipolar
disorder (BD).
Methods. Overall, 173 subjects, patients with BD in euthymic phase (n = 76) and HC (n = 97),
were evaluated through the reduced Morningness–Eveningness Questionnaire (rMEQ), acti-
graphy monitoring and mood and panic-agoraphobic spectrum self-report (MOODS-SR and
PAS-SR). The discrepancy between objective (actigraphic-based) versus subjective (rMEQ-
based) circadian typology was estimated through the Circadian Classification Discrepancy
Index (CCDI).
Results. rMEQ-based evening chronotype (ET) was associated with higher scores in MOODS-
SR depressive and rhythmicity and vegetative functions domains in HC and BD.Both ET and
morning chronotypes (MT) were associated with higher PAS-SR scores in BD only.
Actigraphic-based MT was associated with higher MOODS-SR depressive scores in
HC. Likewise, the discrepancy between actigraphic-based and rMEQ-based circadian typology
was associated with depressive symptoms in HC only.
Conclusion. Self-reported ET was consistently associated with mood symptoms, while associ-
ations with panic-agoraphobic symptoms only emerged in BD and involved both extreme
chronotypes. The discrepancy between the preferred circadian typology (rMEQ-based) and the
actual one (actigraphic-based) could contribute to depressive symptoms in HC. These results
pave the way for interventional studies targeting circadian typology in an attempt to prevent or
treat mental health disorders
L’esercizio del diritto al di là della terapia. Lo human enhancement
Human Enhancement is a modification aimed at improving individual human performance through scientific or technological interventions in the human body. Sure enough, it is based on techniques aimed to improve the knowledge, to change the physique appearance, to increase the physique and the athletic performance, to intensify the working capabilities. The Authors propose to identify the ethical and juridical frames, as well as the medical legal and medical social ones, in which to assimilate the enhancement, duly considering that it's inevitable, since human beings are naturally competitive and since the change is constant and it's the historical main character of every social and cultural revolution, in other words it's the main reason of our evolution. Therefore, we need to value if the application of the enhancement technologies is harmful of the human dignity or if it's an useful tool to improve the human life's condition and then his own dignity
Novel Pharmacological Targets of Post-Traumatic Stress Disorders
Post-traumatic stress disorder (PTSD) is a psychopathological condition with a heteroge-
neous clinical picture that is complex and challenging to treat. Its multifaceted pathophysiology
still remains an unresolved question and certainly contributes to this issue. The pharmacological
treatment of PTSD is mainly empirical and centered on the serotonergic system. Since the therapeutic
response to prescribed drugs targeting single symptoms is generally inconsistent, there is an urgent
need for novel pathogenetic hypotheses, including different mediators and pathways. This paper was
conceived as a narrative review with the aim of debating the current pharmacological treatment of
PTSD and further highlighting prospective targets for future drugs. The authors accessed some of the
main databases of scientific literature available and selected all the papers that fulfilled the purpose of
the present work. The results showed that most of the current pharmacological treatments for PTSD
are symptom-based and show only partial benefits; this largely reflects the limited knowledge of its
neurobiology. Growing, albeit limited, data suggests that the hypothalamic-pituitary-adrenal axis,
opioids, glutamate, cannabinoids, oxytocin, neuropeptide Y, and microRNA may play a role in the
development of PTSD and could be targeted for novel treatments. Indeed, recent research indicates
that examining different pathways might result in the development of novel and more efficient drugs
The fate of the homoctenids (Tentaculitoidea) during the Frasnian-Famennian mass extinction (Late Devonian)
The homoctenids (Tentaculitoidea) are small, conical-shelled marine animals which are amongst the most abundant and widespread of all Late Devonian fossils. They were a principal casualty of the Frasnian-Famennian (F-F, Late Devonian) mass extinction, and thus provide an insight into the extinction dynamics. Despite their abundance during the Late Devonian, they have been largely neglected by extinction studies. A number of Frasnian-Famennian boundary sections have been studied, in Poland, Germany, France, and the United States. These sections have yielded homoctenids, which allow precise recognition of the timing of the mass extinction. It is clear that the homoctenids almost disappear from the fossil record during the latest Frasnian “Upper Kellwasser Event”. The coincident extinction of this pelagic group, and the widespread development of intense marine anoxia within the water column, provides a causal link between anoxia and the F-F extinction. Most notable is the sudden demise of a group, which had been present in rock-forming densities, during this anoxic event. One new species, belonging to Homoctenus is described, but is not formally named here
Insight from an Italian Delphi Consensus on EVAR feasibility outside the instruction for use: the SAFE EVAR Study
BACKGROUND: The SAfety and FEasibility of standard EVAR outside the instruction for use (SAFE-EVAR) Study was designed to define the attitude of Italian vascular surgeons towards the use of standard endovascular repair (EVAR) for infrarenal abdominal aortic aneurysm (AAA) outside the instruction for use (IFU) through a Delphi consensus endorsed by the Italian Society of Vascular and Endovascular Surgery (Societa Italiana di Chirurgia Vascolare ed Endovascolare - SICVE). METHODS: A questionnaire consisting of 26 statements was developed, validated by an 18 -member Advisory Board, and then sent to 600 Italian vascular surgeons. The Delphi process was structured in three subsequent rounds which took place between April and June 2023. In the first two rounds, respondents could indicate one of the following five degrees of agreement: 1) strongly agree; 2) partially agree; 3) neither agree nor disagree; 4) partially disagree; 5) strongly disagree; while in the third round only three different choices were proposed: 1) agree; 2) neither agree nor disagree; 3) disagree. We considered the consensus reached when >70% of respondents agreed on one of the options. After the conclusion of each round, a report describing the percentage distribution of the answers was sent to all the participants. RESULTS: Two -hundred -forty-four (40.6%) Italian Vascular Surgeons agreed to participate the first round of the Delphi Consensus; the second and the third rounds of the Delphi collected 230 responders (94.3% of the first -round responders). Four statements (15.4%) reached a consensus in the first rounds. Among the 22 remaining statements, one more consensus (3.8%) was achieved in the second round. Finally, seven more statements (26.9%) reached a consensus in the simplified last round. Globally, a consensus was reached for almost half of the proposed statements (46.1%). CONCLUSIONS: The relatively low consensus rate obtained in this Delphi seems to confirm the discrepancy between Guideline recommendations and daily clinical practice. The data collected could represent the source for a possible guidelines' revision and the proposal of specific Good Practice Points in all those aspects with only little evidence available
Guidelines on the diagnosis, treatment and management of visceral and renal arteries aneurysms: a joint assessment by the Italian Societies of Vascular and Endovascular Surgery (SICVE) and Medical and Interventional Radiology (SIRM)
: The objective of these Guidelines is to provide recommendations for the classification, indication, treatment and management of patients suffering from aneurysmal pathology of the visceral and renal arteries. The methodology applied was the GRADE-SIGN version, and followed the instructions of the AGREE quality of reporting checklist. Clinical questions, structured according to the PICO (Population, Intervention, Comparator, Outcome) model, were formulated, and systematic literature reviews were carried out according to them. Selected articles were evaluated through specific methodological checklists. Considered Judgments were compiled for each clinical question in which the characteristics of the body of available evidence were evaluated in order to establish recommendations. Overall, 79 clinical practice recommendations were proposed. Indications for treatment and therapeutic options were discussed for each arterial district, as well as follow-up and medical management, in both candidate patients for conservative therapy and patients who underwent treatment. The recommendations provided by these guidelines simplify and improve decision-making processes and diagnostic-therapeutic pathways of patients with visceral and renal arteries aneurysms. Their widespread use is recommended
