Cholangiocarcinoma According to Different Etiologies
This scenario is even more complex in the context of cholangiocarcinoma (CCA), which encompasses an extremely heterogeneous group of malignancies arising from the intrahepatic (iCCA) and extrahepatic (eCCA) biliary tree. The molecular heterogeneity of CCA has been observed not only when comparing iCCA and eCCA subtypes, but also among patients with the same cancer type (inter-patient heterogeneity), and even across the different topographic regions of the tumor from the same patient (intra-patient heterogeneity).

Impact of COVID-19 on Hospital Profit Compensation Activities
The impact of the 2019 coronavirus disease (COVID-19) pandemic is still being felt, and little is known about the impact on hospital operations of the loss of outpatients and inpatients due to COVID-19 in many counties. Therefore exploring whether hospitals have adopted profit-compensation activities following the first wave of the COVID-19 outbreak in China in 2020. 2616589 inpatient records for 2018, 2019, and 2020 were extracted from 36 tertiary hospitals in a western province; a difference-in-difference event study design was used to estimate the dynamic impact of COVID-19 on total inpatient costs before and after the last confirmed case. An increase in mean total costs per patient of between 8.7% and 16.7% can be found in the first 25 weeks after urban reopening and return to normal hospitalization. It indicates that hospitals experienced profit compensating activity after the first wave of the outbreak in China in 2020, driven by the reduction in hospital admissions during that wave.

Specific Foods and Cancer Mortality
Many cancers are associated with poor diet, lack of physical activity, and excess weight. Improving any of these three lifestyle factors would likely reduce cancer deaths.

The African Wastewater Resistome
In Africa, the prevalence of Antimicrobial Resistance (AMR)  in wastewater is of particular concern due to the inadequate sanitation and wastewater treatment facilities, coupled with the overuse and misuse of antibiotics in healthcare and agriculture.

Microneedles for SARS-CoV-2 Mass Vaccination
Vaccination is an effective measure to prevent infectious diseases. Protective immunity is induced when the immune system is exposed to a vaccine formulation with appropriate immunogenicity. However, traditional injection vaccination is always accompanied by fear and severe pain. As an emerging vaccine delivery tool, microneedles overcome the problems associated with routine needle vaccination, which can effectively deliver vaccines rich in antigen-presenting cells (APCs) to the epidermis and dermis painlessly, inducing a strong immune response. In addition, microneedles have the advantages of avoiding cold chain storage and have the flexibility of self-operation, which can solve the logistics and delivery obstacles of vaccines, covering the vaccination of the special population more easily and conveniently.

Rehabilitation of Gait and Balance in Cerebral Palsy
Cerebral palsy (CP) is a congenital and permanent neurological disorder due to non-progressive brain damage that affects gross motor functions, such as balance, trunk control and gait. CP gross motor impairments yield more challenging right foot placement during gait phases, as well as the correct direction of the whole-body center of mass with a stability reduction and an increase in falling and tripping. For these reasons, robotic devices, thanks to their biomechanical features, can adapt easily to CP children, allowing better motor recovery and enjoyment. In fact, physiotherapists should consider each pathological gait feature to provide the patient with the best possible rehabilitation strategy and reduce extra energy efforts and the risk of falling in children affected by CP.

Mesenchymal Stem Cell-Derived Extracellular Vesicles
Mesenchymal stem cells (MSCs) have recently emerged as promising candidates for treating a variety of age-related conditions, including ageing frailty. MSCs can differentiate into different cell lineages and secrete extracellular vesicles (EVs), such as exosomes and microvesicles, that contain bioactive molecules, such as proteins, nucleic acids, and lipids. These EVs can deliver cargo to target cells and influence cellular processes, such as inflammation, apoptosis, and angiogenesis, promoting tissue repair and regeneration.

Oral Supplementation for the Improvement of Fatigue Symptoms
Fatigue, characterised by lack of energy, mental exhaustion and poor muscle endurance which do not recover following a period of rest, is a common characteristic symptom of several conditions and negatively impacts the quality of life of those affected. Fatigue is often a symptom of concern for people suffering from conditions such as fibromyalgia, chronic fatigue syndrome, cancer, and multiple sclerosis. Vitamins and minerals, playing essential roles in a variety of basic metabolic pathways that support fundamental cellular functions, may be important in mitigating physical and mental fatigue.

Therapeutic Implications of Splanchnic Vein Thrombosis
Splanchnic vein thrombosis (SVT) includes portal (portal vein thrombosis, PVT), mesenteric (mesenteric vein thrombosis, MVT) and splenic vein thrombosis, and Budd-Chiari syndrome (BCS). SVT is generally classified as secondary to an identified risk factor or primitive, unprovoked, when causative factors cannot be identified. While much rarer than common venous thromboembolism (VTE), SVT is often challenging to clinicians for both the identification of the causal disorder and for its therapeutic management. The therapeutic approach of SVT is a clinical challenge and considers the manifestations and the site of thrombosis, the risk of SVT progression, recurrence and bleeding. The decision regarding when to start, as well as the type and the duration of anticoagulant therapy is often made empirically.

Diagnosis and Management of Mandibular Crowding
Crowding is the most frequent malocclusion in orthodontics, with a strong hereditary tendency. It already occurs in pediatric age and is mainly hereditary. It is a sign of a lack of space in the arches, and is not self-correcting, but can worsen over time. The main cause of the worsening of this malocclusion is a progressive and physiological decrease in the arch perimeter.  An orthodontic treatment cannot ignore the concept of “guide arch”, which concerns the lower arch, because of the objective difficulty in increasing its perimeter; the bone structure of the lower jaw is more compact than that of the upper one. Its expansion, in fact, is limited to a slight vestibularization of the incisors and lateral sectors that may be associated with a limited distalization of the molars. There are various therapeutic solutions available to the orthodontist, and a correct diagnosis through clinical examination, radiographs and model analysis are essential. The decision of how to deal with crowding cannot be separated from an overall assessment of the malocclusion to be treated.
