Planetary health research: insights from The Lancet Planetary Health original articles

Background

In 2017, the Lancet group launched The Lancet Planetary Health to promote the dissemination of research conducted in this field. Planetary health was also extensively discussed during the World Congress on Public Health 2020, which underlines the strategic importance recognized to this topic by experts and researchers active in public health at an international level. The aim was to investigate the role of public health university departments in the field of planetary health.

Methods

The Lancet Planetary Health database was queried from the inception to February 2021, to retrieve original articles or reviews whose first and/or last author was affiliated to a University Department of Public Health worldwide. We used the twenty-six EUPHA operational sections to define the research areas of the identified articles. The following data were extracted: study design, EUPHA area, research question, topic, identified gaps in the literature, and key concepts.

Results

Out of 543 entries, 44 original articles and reviews were included. Thirty-two percent studies were conducted in Asia, 20% in America, 13% in Europe, 8% in Oceania, 4% in Africa while 23% in a multicentric global context. The area investigated was mainly environmental and health (68%) followed by infectious disease control (14%). Collaboration across different disciplines is highly present in the authorships. Regarding the study design, 30% of the included articles were cohort studies.

Conclusions

From 2017 till February 2021, the number of studies performed by public health researchers published on The Lancet Planetary Health is gradually increasing.

Since published articles take advantage of the typical research methods and topics of public health and environmental health research, public health university departments can contribute to planetary health science if they seek transdisciplinary collaboration and adopt a planetary health vision.

Leadership in Public Health: an Italian learning experience

Background

The “Public Health Leadership” Working Group of Italian Society of Public Health (S.It.I.) organized a two-days Workshop in Verona in January 2020. Leadership is linked to capacity of inspiring people to craft and achieve vision and goals, to provide mentoring, coaching and recognition and to encouragement empowerment, allowing other leaders to emerge and high quality of care. As in others country, in Italy investing in new generations is fundamental and far-sighted to create Leadership culture in tomorrow's professionals.

Objectives

The Workshop aim was to immerse Public Health residents into Health Leadership. Two types of practical/interactive experiences (Design thinking and Barometer strategy) and three speakers' interventions aroused curiosity, suggesting innovative ways to manage emerging local and global healthcare problems. Are residents interested in Leadership? Do they think Leadership could influence, motivate and enable to contribute to organization effectiveness?

Results

100 residents (Male 52, Female 48), from 72% of Public Health Schools (26), attended Workshop: 46 of 1st, 23 of 2nd, 18 of 3rd and 13 of residency program last year. Satisfaction questionnaire was completed by 58 residents (7 points Likert scale from 1 [dissatisfied/not useful] to 7 [satisfied/useful]). 5.91 pts result in interventions satisfaction, increasing from 1st (5.84) to last year (6.00); interventions topics deepening results in 5.38 pts, decreasing from 1st (5.52) to last year (5.00). Overall satisfaction on practical/interactive activities was 5.89 and 5.83 pts results in these methodologies usefulness.

Conclusions

Health Leadership is a hot topic for residents; during residency program Leadership in not a main theme and residents want to improve non-technical skills to realise organization high quality of care. The practical/interactive activities were a winning choice to capture attention and cultivate mutual trust. This experience could be adapted in other countries.

Key messages

Teaching Leadership in Public Health is a main topic that needs to be strengthened in Public Health agenda. Italian Public Health residents are very interested in Health Leadership improvement during their trainings.

An automatic platform to monitor Web 2.0 presence of Healthcare Providers in Italy

Background

Healthcare providers (HP) need to involve the population to spread correct and useful health information and to gather feedback on the perceived quality of the service. Web 2.0, based on the use of Social Networks (SN), allows direct communication between the HP and the population. We built an automatic platform which monitors Web 2.0 usage by Italian public and private HP.

Methods

For each HP the platform finds the relative website using Google searches and extracts the links to SN. For Facebook and Twitter, it retrieves one year of content and identifies common topics via natural language processing. Finally, it compares the Web 2.0 usage patterns and topics with the type of HP and geographical position.

Results

In 2017, on 540 HP screened 97.8% had a website (309 unique sites, many HP have a common site). 37.5% of the websites had links to SN in the homepage: Youtube (YT) was the most common (74.1%), then Facebook (FB, 72.4%) and Twitter (TW, 51.7%). The presence of SN was lower in the south (OR: 0.63; p < 0.001) while is higher for research centers (OR: 5.12; p < 0.001) and private hospitals (OR: 2.12; p = 0.004). Local Health Trusts were the most active on FB (1.86 more posts, p = 0.004) but research centers had more fans RR: 5.32; p = 0.003) and likes per post (RR: 4.95; p < 0.001). On TW private hospitals had the most followers (RR: 3.35; p = 0.002) and likes per tweet (RR: 3.95; p < 0.001). The most posted topics were on healthy behaviors and organizational changes, while a lower number of posts were on healthy food and vaccines. Posts on specific pathologies information and healthy behaviors received more likes.

Conclusions

We propose an automatic platform that monitors the internet presence of HP in Italy, helping to define the best strategies for effective health communication. We found that in the south and in the public sector the importance of this tool is less perceived, with a lower SN presence and a gap between posted topics and those appreciated by the public.

Key messages

We propose an automatic platform that reports and monitors the web 2.0 presence and usage by HP in Italy, helping to define the best strategies to spread effective health communication. In Italy the presence of SN among HP is lower in the south and in the public, while is higher for research centers. HP have to engage the population maximizing the potentiality of web 2.0.

Centrality dependence of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at sqrt[s(NN)] = 2.76 TeV

The centrality dependence of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at sqrt[s_{NN}]=2.76  TeV is presented. The charged-particle density normalized per participating nucleon pair increases by about a factor of 2 from peripheral (70%-80%) to central (0%-5%) collisions. The centrality dependence is found to be similar to that observed at lower collision energies. The data are compared with models based on different mechanisms for particle production in nuclear collisions.

Elliptic flow of charged particles in Pb-Pb collisions at sqrt[S(NN)] = 2.76 TeV

We report the first measurement of charged particle elliptic flow in Pb-Pb collisions at sqrt[S(NN)] =2.76 TeV with the ALICE detector at the CERN Large Hadron Collider. The measurement is performed in the central pseudorapidity region (|η|<0.8) and transverse momentum range 0.2<p t<5.0 GeV/c. The elliptic flow signal v₂, measured using the 4-particle correlation method, averaged over transverse momentum and pseudorapidity is 0.087 ± 0.002(stat) ± 0.003(syst) in the 40%-50% centrality class. The differential elliptic flow v₂ p t reaches a maximum of 0.2 near p t =3 GeV/c. Compared to RHIC Au-Au collisions at sqrt[S(NN)] 200 GeV, the elliptic flow increases by about 30%. Some hydrodynamic model predictions which include viscous corrections are in agreement with the observed increase.

Charged-particle multiplicity density at midrapidity in central Pb-Pb collisions at sqrt[S(NN)] = 2.76 TeV

The first measurement of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at a center-of-mass energy per nucleon pair √ S NN = 2.76 TeV is presented. For an event sample corresponding to the most central 5% of the hadronic cross section, the pseudorapidity density of primary charged particles at midrapidity is 1584 ± 4(stat) ± 76(syst), which corresponds to 8.3 ± 0.4(syst) per participating nucleon pair. This represents an increase of about a factor 1.9 relative to pp collisions at similar collision energies, and about a factor 2.2 to central Au-Au collisions at √ S NN = 2.76 TeV. This measurement provides the first experimental constraint for models of nucleus-nucleus collisions at LHC energies.

Midrapidity antiproton-to-proton ratio in pp collisons at sqrt[s]=0.9 and 7 TeV measured by the ALICE experiment

The ratio of the yields of antiprotons to protons in pp collisions has been measured by the ALICE experiment at sqrt[s]=0.9 and 7 TeV during the initial running periods of the Large Hadron Collider. The measurement covers the transverse momentum interval 0.45<p_{t}<1.05  GeV/c and rapidity |y|<0.5. The ratio is measured to be R_{|y|<0.5}=0.957±0.006(stat)±0.014(syst) at 0.9 TeV and R_{|y|<0.5}=0.991±0.005(stat)±0.014(syst) at 7 TeV and it is independent of both rapidity and transverse momentum. The results are consistent with the conventional model of baryon-number transport and set stringent limits on any additional contributions to baryon-number transfer over very large rapidity intervals in pp collisions.
