Interplay of network dynamics and ties heterogeneity on spreading dynamics
The structure of a network dramatically affects the spreading phenomena
unfolding upon it. The contact distribution of the nodes has long been
recognized as the key ingredient in influencing the outbreak events. However,
limited knowledge is currently available on the role of the weight of the edges
on the persistence of a pathogen. At the same time, recent works showed a
strong influence of temporal network dynamics on disease spreading. In this
work we provide an analytical understanding, corroborated by numerical
simulations, about the conditions for infected stable state in weighted
networks. In particular, we reveal the role of heterogeneity of edge weights
and of the dynamic assignment of weights on the ties in the network in driving
the spread of the epidemic. In this context we show that when weights are
dynamically assigned to ties in the network an heterogeneous distribution is
able to hamper the diffusion of the disease, contrary to what happens when
weights are fixed in time.Comment: 10 pages, 10 figure
I.S.Mu.L.T. Achilles Tendon Ruptures Guidelines
This work provides easily accessible guidelines for the diagnosis, treatment and rehabilitation of Achilles tendon ruptures. These guidelines could be considered as recommendations for good clinical practice developed through a process of systematic review of the literature and expert opinion, to improve the quality of care for the individual patient and rationalize the use of resources. This work is divided into two sessions: 1) questions about hot topics; 2) answers to the questions following Evidence Based Medicine principles. Despite the frequency of the pathology andthe high level of satisfaction achieved in treatment of Achilles tendon ruptures, a global consensus is lacking. In fact, there is not a uniform treatment and rehabilitation protocol used for Achilles tendon ruptures

Managing a Tertiary Orthopedic Hospital during the COVID-19 Epidemic, Main Challenges and Solutions Adopted
The present paper is a review of the main challenges faced by the management of a tertiary specialty hospital during the COVID-19 pandemic in the northern Italian region of Lombardy, an area of extremely high epidemic impact. The article focuses on the management of patient flows, access to the hospital, maintaining and reallocating staffing levels, and managing urgent referrals, information, and communications from the point of view of the hospital managers over a seven-week period. The objective of the article is to provide beneficial insights and solutions to other hospital managers and medical directors who should find themselves in the same or a similar situation. In such an epidemic emergency, in the authors’ opinion, the most important factors influencing the capability of the hospital to maintain operations are (1) sustaining the strict triage of patients, (2) the differentiation of flows and pathways to create what could be regarded as “a hospital inside a hospital”, (3) tracing and sharing all available information to face the rapidly changing environment, (4) being able to maintain staffing levels in critical areas by flexibly allocating the workforce, and (5) from a regional perspective, being organized along a hub-and-spoke system for critical and time-sensitive networks was key for focusing the hospital’s resources on the most needed services
The Central Role of Iron in Human Nutrition: From Folk to Contemporary Medicine
Iron is a fundamental element in human history, from the dawn of civilization to contemporary days. The ancients used the metal to shape tools, to forge weapons, and even as a dietary supplement. This last indication has been handed down until today, when martial therapy is considered fundamental to correct deficiency states of anemia. The improvement of the martial status is mainly targeted with dietary supplements that often couple diverse co-factors, but other methods are available, such as parenteral preparations, dietary interventions, or real-world approaches. The oral absorption of this metal occurs in the duodenum and is highly dependent upon its oxidation state, with many absorption influencers possibly interfering with the intestinal uptake. Bone marrow and spleen represent the initial and ultimate step of iron metabolism, respectively, and the most part of body iron circulates bound to specific proteins and mainly serves to synthesize hemoglobin for new red blood cells. Whatever the martial status is, today's knowledge about iron biochemistry allows us to embrace exceedingly personalized interventions, which however owe their success to the mythical and historical events that always accompanied this metal
