The healthcare and pharmaceutical vulnerability emerging from the new Coronavirus outbreak
With a constantly increasing number of
infected people world-wide,
1 the
COVID-19 (2019-nCoV)
outbreak risks
becoming a pandemic emergency, and for
this reason, on 28 February 2020 the
WHO upgraded the global risk of the
coronavirus outbreak to ‘very high’.2 As
many studies have shown, in the first
phase of the onset of 2019-nCoV
there is
an exponential curve of infection with a
reproduction number (R0) ranging from 2
to 5,3 an indication that the spread of the
virus cannot spontaneously decrease. A
significant reduction in these R0 values can
possibly be achieved by implementing
specific containment actions, according to
the results of a study of the evolution of
the infections detected in China .4 The
spread of the virus is favoured by its ability
to be transmitted by asymptomatic
patients,5 a particularly grave consideration,
given that the currently estimated
incubation period extends from 2 to 12
days.6 Furthermore, the easiest screening
methods based on the execution of a nasopharyngeal
swab displayed false negative
results in both asymptomatic and symptomatic
patients,7 making it more complex
to intercept possible infected subjects,
especially before a clinical manifestation
of the infection.
Since its onset in Europe, the 2019-nCoV
emergency has been addressed
by implementing social containment
measures. This is particularly true in Italy,
the first European country struck by an
important 2019-nCoV
outbreak. On 4
March 2020 the national government
approved a series of important social
limitation measures including the closure
of schools and universities, and the quarantine
of exposed persons; it also urges
residents to avoid crowded events, and
has set in motion contact tracing efforts.
Considering that containment of the
spread of the virus seems very unlikely, the
restriction measures adopted by Italy seem
more focused on dilution of the epidemic
peak over a wider timeframe. As reported
in a scientific paper,8 the first outcomes
of these measures would be to buy time
for preparations in the healthcare system,
to avoid overwhelming the healthcare
system, and to enable better management
of 2019-nCoV
infected patients.
This seems essential for the Italian
health system, as, since 2009, more than
€37 billion have been cut in healthcare
costs and hospital beds have been reduced
to 3.2 per 1000 inhabitants, compared
with a European average of 5 per 1000
inhabitants.9 The number of hospital beds,
in particular, seems to be a crucial issue
in management of the 2019-nCoV
emergency,
which is characterised by the need
for hospitalisation in intensive care units
for >15% of infected patients.10 For this
reason, the Italian government has set up
a 50% increase in the number of beds in
these critical hospital areas and a patient
distribution agreement between healthcare
institutions aimed at avoiding the
collapse of some hospitals affected by a
greater influx of infected patients.11
Delaying the peak of the epidemic could
also be useful for a subsequent introduction
of some pharmacological interventions.
At present, there is no defined
therapeutic protocol to be used on patients
with 2019-nCoV,
and the drugs that
have shown significant efficacy in some
studies,12 13 such as remdesivir, lopinavir/
ritonavir, and hydroxychloroquine, are
currently undergoing phase 3 clinical trials
( ClinicalTrials. gov register). Another aid
that could take place later is the possible
availability of an effective vaccine capable
of blocking the virus spread. Currently
>15 vaccines are in the pipeline12 but
none are foreseen to be available before
the third quarter of 2020.14
Another important aspect of the global
emergency is certainly linked to its social
impact. Our life dynamics are deeply
influenced by the containment measures,
and for the first time in the 21st century
we are facing a health emergency on a
global scale. However, while solutions
such as remote smart working, video calls
and e-commerce
allow us to carry on with
our lifestyle to some degree, other aspects
of our society such as our global and
connected economy and crucial import
supply chains could be deeply affected.
The supply of medicines is a crucial
issue when facing a global health emergency.
We have become used to hearing
news about shortages of hand sanitiser and
facemasks dictated by so-called
‘panic-buying’,
but a much more serious threat
is the potential shortage of drugs. Locally,
shortages can be linked to increased
demand and difficulties in transport in
the areas most affected by the emergency.
Globally, there could be a remarkable
reduction in the production capability of
pharmaceutical manufacturing facilities
where active pharmaceutical ingredients
(API) are produced, as work is interrupted
to update sanitisation procedures for the
infrastructure and production rooms, or
as scientists, managers and line workers
fall ill with the virus. Moreover, it is well
known that drug makers rely heavily on
ingredients made in Chinese factories.
According to the CEO of Sanofi, 60%
of the world’s API is made in China15
and this could cause supply problems
as the virus’ disruption of the Chinese
economy continues. In fact, a drug was
recently added to the US Food and Drug
Administration’s (FDA’s) Drug Shortages
List specifically because of the effects of
the coronavirus. The manufacturer notified
the FDA that the shortage is due to
problems with the production of an active
pharmaceutical ingredient at a site affected
by coronavirus.16 However, this news is
only the tip of the iceberg, as according
to some sources17 the monitoring of the
risk of shortage related to the 2019-nCoV
would concern “About 150 prescription
drugs—including antibiotics, generics and
some branded drugs without alternatives”.
Unfortunately, not only drug supplies
may risk shortfalls: the production of
medical devices may falter as well. Indeed,
as reported by the FDA, “The agency
reached out to 63 companies with a total
of 72 facilities in China that make essential
medical devices”. FDA Commissioner Dr
Stephen Hahn said that “several of these
facilities in China are adversely affected”
by the epidemic and that their workforces
have taken a hit from the outbreak,
including employees being quarantined.16
These worrying developments provide
an opportunity to discuss economic
realities that create vulnerability in our
healthcare sector. It is becoming clear that
production backup sites are needed to
ensure adequate supplies, even in the most

before this crisis, our healthcare system
had not developed a strategy to deal with
potential epidemics, could provide an
opportunity to reflect on where to act to
be prepared in the event of similar or even
more serious health threats.

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Nesting habits of two spider wasps: Anoplius infuscatus and Episyron sp. (Hymenoptera: Pompilidae), with a review of the literature.
Many behavioural aspects of Anoplius infuscatus (Vander Linden) and Episyron sp. Schioedte were examined in detail, both on a qualitative and, when possible, on a quantitative level, during a long-term fi eld study in Northern Italy. Both wasps dig unicellular nests on bare soil, which are fi lled with a single spider to feed the brood. The main differences regard the way to hunt their prey, that of burrowing, that of transporting and introducing the spider into the nest, the habit of amputating spider legs and the abdominal movements during nest closing. On the whole, starting from prey capture to nest closure, A. infuscatus is signifi cantly slower than Episyron. The observed ethological differences
are well fi tted to the exploitation of the different preys consisting in wolf spiders (Lycosidae) and orb weaving spiders (Araneidae), respectively. Some fl exibility in the observed behaviour is described.
A critical re-examination of the literature shows that, even if most results agree with those of previous authors, two controversial points remain open regarding Episyron species: the position of the egg (on the prey or on the cell wall) and the way to grasp the spider during tranport and introdution into the nest
Temporal transition of nesting activities in the digger wasp Bembecinus tridens (Hymenoptera, Crabronidae).
A nest aggregation of Bembecinus tridens (Hymenoptera: Crabronidae) was investigated through observations of marked
individual females in Northern Italy, in order to quantify frequencies, duration, and sequence of the nesting activities. Wasp
females dug unicellular (in one case multicellular) nests preferably on oblique surfaces. Nest digging occurred mainly in the
morning, while definitive nest closing was performed only in the afternoon, and nests were frequented by the owners for
3.52 days on average. One to eight nests were dug by single females in rapid succession in the area observed, revealing a
rapid dispersion towards other sites. Provisioning and non-provisioning (control) flights were positively correlated and
occurred mainly in the late morning. A number of orientation flights followed most exits from the nests but was higher at the
end of nest digging. Nest closing lasted more at the end of provisioning and at the end of digging. Provisioning began more
frequently one day after nest digging (and oviposition), less frequently two days after, and the number of prey per day was
negatively correlated with the number of provisioning days. Data are consistent with a situation of primitive progressive
provisioning, and match that of other species of the same genus
Chronic intracerebroventricular infusion of nociceptin/orphanin FQ increases food and ethanol intake in alcohol-preferring rats
Central administration of low doses of nociceptin/orphanin FQ (N/OFQ), the endogenous
ligand of the opioid-like orphan receptor NOP, have been shown to reduce ethanol consumption,
ethanol-induced conditioned place preference and stress-induced reinstatement
of alcohol-seeking behavior in alcohol preferring rats. The present study evaluated the effect
of continuous (7 days) lateral brain ventricle infusions of N/OFQ (0, 0.25, 1, 4, and 8 mg/h), by
means of osmotic mini-pumps, on 10% ethanol intake in Marchigian-Sardinian alcoholpreferring
(msP) rats provided 2 h or 24 h access to it. N/OFQ dose-dependently increased
food intake in msP rats. On the other hand, in contrast to previous studies with acute
injections, continuous lateral brain ventricle infusion of high doses of N/OFQ increased
ethanol consumption when the ethanol solution was available for 24 h/day or 2 h/day. The
present study demonstrates that continuous activation of the opioidergic N/OFQ receptor
does not blunt the reinforcing effects of ethanol. Moreover, the data suggest that continuous
activation of the opioidergic N/OFQ receptor is not a suitable way to reduce alcohol abuse
Age-related changes in the visual cortex: a review.
The main age related changes in visual cortex are reviewed. The visual cortex (occipital cortex, areas 17-19) undergoes a variety of anatomical, biochemical and functional changes with aging. From a morphological point of view the visual cortex loses nerve cells mainly in the last period of life. From a biochemical point of view cholinergic, serotonergic, and GABAergic neurotransmissions seem to be the most remarkably affected. In terms of functional correlates, a decline of several activities of the visual cortex has been documented in the elderly. Due to the importance of visual cortex in the realization of visual function, the influence of aging on this cerebrocortical area requires a more detailed analysis
