The diet of Weddell seals (Leptonychotes weddellii) in Terra Nova Bay using stable isotope analysis

Stable isotope analyses were used to investigate the diet of Weddell seals in Terra Nova Bay (Ross Sea) and the potential variation of their foraging behaviour with age, sex and body mass. For this purpose, skin samples were collected from adult breeding seals and pups, together with muscle samples of their potential prey. Our results showed variation in foraging behavior between age classes, with pups reporting lower δ13C values than adults, while no significant differences in δ15N were recorded. In addition, contrary to expectations, a mixing model analysis showed that adult seals foraged mainly on shallow benthic prey, such as Trematomus spp. (34.1%) and Dissostichus mawsoni (21.1%), rather than on pelagic fish, such as Pleuragramma antarcticum (9.8%). Overall, with this paper we provide novel diet information on a seal colony not previously sampled, adding new insight into the feeding ecology of a top Antarctic predator

Economic impact of remote monitoring on ordinary follow-up of implantable cardioverter defibrillators as compared with conventional in-hospital visits: a single-center prospective and randomized study

Few data are available on actual follow-up costs of remote monitoring (RM) of implantable defibrillators (ICD). Our study aimed at assessing current direct costs of 1-year ICD follow-up based on RM compared with conventional quarterly in-hospital follow-ups. Methods and results Patients (N=233) with indications for ICD were consecutively recruited and randomized at implant to be followed up for 1 year with standard quarterly inhospital visits or by RM with one in-hospital visit at 12 months, unless additional in-hospital visits were required due to specific patient conditions or RM alarms. Costs were calculated distinguishing between provider and patient costs, excluding RM device and service cost. The frequency of scheduled in-hospital visits was lower in the RM group than in the control arm. Follow-up required 47 min per patient/year in the RM arm versus 86 min in the control arm (p=0.03) for involved physicians, generating cost estimates for the provider of USD 45 and USD 83 per patient/- year, respectively. Costs for nurses were comparable. Overall, the costs associated with RM and standard follow-up were USD 103±27 and 154±21 per patient/year, respectively (p=0.01). RM was cost-saving for the patients: USD 97±121 per patient/year in the RM group versus 287± 160 per patient/year (p=0.0001). Conclusion The time spent by the hospital staff was significantly reduced in the RM group. If the costs for the device and service are not charged to patients or the provider, patients could save about USD 190 per patient/year while the hospital could save USD 51 per patient/year

Genome-based study of a spatio-temporal cluster of invasive meningococcal disease due to Neisseria meningitidis serogroup C, clonal complex 11

Summary Objectives To describe a spatio-temporal cluster of invasive meningococcal disease (IMD) due to serogroup C meningococci, occurred in a restricted area of Tuscany between January and October 2015, and the results of whole genome sequencing (WGS). Methods Surveillance activities and public health measures were implemented in the Region. Bacterial isolates from IMD cases were characterized by the National Reference Laboratory of the Istituto Superiore di Sanita (ISS), and WGS was performed on available strains. The kSNP software was used to identify core genome SNPs. Results Overall, 28 IMD cases due to meningococcus C were identified up to 31st October, 2015. Of them, 26 were due to meningococcus C:P1.5-1,10-8: F3-6:ST-11 (cc11) and 2 to C:P1.5-1,10-8: F3-6:ST-2780 (cc11). WGS of 13 meningococci isolated during the outbreak occurred in Tuscany in 2015 showed higher similarity when compared with those of 47 C: P1.5-1,10-8: F3-6:ST-11 (cc11) invasive strains from sporadic cases previously detected in Italy. Conclusions A highly aggressive meningococcal C strain was involved in the cluster of severe IMD occurred in Tuscany, a Region with high vaccine coverage among children. Whether this was due to low herd immunity related to the short duration of vaccine protection needs further investigation

Meningococci of serogroup X clonal complex 181 in refugee camps, Italy

Four cases of infection with serogroup X meningococci (MenX) (1 in 2015 and 3 in 2016) occurred in migrants living in refugee camps or reception centers in Italy. All MenX isolates were identified as clonal complex 181. Our report suggests that serogroup X represents an emerging health threat for persons arriving from African countries

Enhancing the Sustainable Goal of Access to Healthcare: Findings from a Literature Review on Telemedicine Employment in Rural Areas

Fighting health inequalities is a challenge addressed by the United Nations Strategic Development Goals (UN-SDGs). Particularly, people living in rural areas suffer from a lack of health infrastructure, which would jeopardize their inclusion in universal coverage for specialist care. Delivering valuable healthcare in underserved areas can be achieved through the employment of new technical innovations, such as telemedicine, which improves service delivery processes. Accordingly, this paper discusses how telemedicine strategies have enhanced the sustainability of right of “access to healthcare” in rural areas. Once we derived the sustainability pillars for healthcare from the UN-SDGs 3 and 10 according to the WHO innovation assessment metrics, a PRISMA-based literature review was conducted using the Scopus database. English, peer-reviewed articles/reviews from 1973 to 2019 were considered. The enquiry covers two analyses: (i) quantitative-bibliometric on 2267 papers; and (ii) qualitative-narrative on the 30 most significant papers. Interest about the topic has increased in the last decade following digitalization diffusion. The most productive and collaborative countries are those with huge dimensions and under financial restrictions. From a sustainability-oriented standpoint, telemedicine enhances both emergency and diagnostic healthcare in rural areas by decreasing the cost of services, expanding coverage of specialist cares, and increasing the quality of the outcomes. For health policies, telemedicine can be considered a suitable solution for providing cost-effective and sustainable healthcare

Remote Management of Hearth Failure the post discharge period: review of cost analysis and cost sustainability for Hospitals in the perspective of th National Health System

Heart Failure (HF) can be considered among the most expensive diseases for the National Health System in Italy (1,4% of the yearly expenditure); it is related to high levels of mortality and morbidity, and long hospitalization periods. This means that the largest part of costs is related to direct health assistance. Data on managing by telemedicine of post discharge periods in HF are scarce. A trial was conducted after a review on Health Care Management, and Health Technology Assessment literature, about telecardiology implications on cost accounting. For 12 months, forty patients affected by HF, implanted with ICD remote control just after discharge from the hospital were observed. The analysis showed, through an accurate cost accounting examination, that the use of telemedicine is cost effective because it allows hospitals to know the health condition of patients before they get worse. These information allow to predict and prevent relapses of HF and new hospitalization (reduced by more than 65%), with a consequent cost saving of about 65% for the same clinical outcome of alternative health treatments
