Drug delivery systems (DDSs) represent an emerging focus for many researchers and they are becoming progressively crucial in the development of new treatments. Great attention is given to all the challenges that a drug has to overcome during its journey across barriers and tissues and all the pharmacokinetics modulations that are needed in order to reach the targeting sites. The goal of these pathways is the delivery of drugs in a controlled way, optimizing their bioavailability and minimizing side effects. Recent innovations in DDSs include various nanotechnology-based approaches, such as nanoparticles, nanofibers and micelles, which provide effective targeted delivery and sustained release of therapeutics. In this context, protein-based drug delivery systems are gaining significant attention in the pharmaceutical field due to their potential to revolutionize targeted and efficient drug delivery. As natural biomolecules, proteins offer distinct advantages, including safety, biocompatibility and biodegradability, making them a fascinating alternative to synthetic polymers. Moreover, protein-based carriers, including those derived from gelatin, albumin, collagen, gliadin and silk proteins, demonstrate exceptional stability under physiological conditions, and they allow for controlled and sustained drug release, enhancing therapeutic efficacy. This review provides a comprehensive overview of the current trends, challenges, and future perspectives in protein-based drug delivery, focusing on the types of proteins adopted and the techniques that are being developed to enhance their functionality in terms of drug affinity and targeting capabilities, underscoring their potential to significantly impact modern therapeutics.

Background: During rapid maxillary expansion (RME), heavy forces are transmitted to the maxilla by the anchored teeth causing buccal inclination and buccal bone loss of posterior teeth. Objective: To systematically review the literature in order to investigate whether RME causes periodontal sequelae, assessed by cone-beam computed tomography (CBCT). Search methods: Fifteen electronic databases and reference lists of studies were searched up to March 2017. Selection criteria: To be included in the systematic review, articles must be human studies on growing subjects, with transversal maxillary deficiency treated with RME and with assessment of buccal bone loss by CBCT images. Only randomized and non-randomized trials were included. Data collection and analysis: Two authors independently performed study selection, data extraction, and risk of bias assessment. Study characteristics (study design, sample size, age, sex, skeletal maturity, type of appliance, daily activation, evaluated linear measurements, observation period, CBCT settings), and study outcomes (loss of buccal bone thickness and marginal bone) were reported according to the PRISMA statement. Results: On the basis of the applied inclusion criteria, only six articles, three randomized clinical trials and three controlled clinical trials were included. An individual analysis of the selected articles was undertaken. The risks of bias of the six trials were scored as medium to low. Limitations: The results of the present systematic review are based on a limited number of studies and only one study included a control group. Conclusions and implications: In all considered studies, significant loss of buccal bone thickness and marginal bone level were observed in anchored teeth, following RME. Further prospective studies correlating the radiological data of bone loss to the periodontal soft tissues reaction after RME are required. A preliminary evaluation of the patient-related risk factors for RR may be advisable when considering to administering RME. [ABSTRACT FROM AUTHOR]

Background: Evidence on the negative outcomes of untreated mental disorders during pregnancy and in the first year after childbirth on women's and children's health has stimulated interest in how to develop and sustain high-quality mental health care during the perinatal period. In Italy, there is a lack of knowledge about how mental health services support women with perinatal mental disorders (PMDs). This study aims to describe the adoption of good practices for the prevention and care of PMDs by the Italian mental health departments (MHDs)., Methods: This is a nationwide cross-sectional survey conducted online using LimeSurvey. Starting from the Ministry of Health Registry's 127 MHDs were invited to participate between February and March, 2023. Characteristics of the participating MHDs were reported as descriptive statistics., Results: One hundred nineteen MHDs participated, with a response rate of 93.7%. Regarding the prevention of PMDs, 69 (58.0%) MHDs offer preconception counseling, whereas only 6 (5.0%) have information material for this purpose. Written integrated care pathways for PMDs are not available in 94 (79.7%) MHDs. A reference professional for psychopharmacological treatment during pregnancy or breastfeeding is available in 55 (46.2%) MHDs, while a specific treatment plan for women with PMDs is adopted by 27 (22.7%) MHDs. Thirty-four (28.6%) MHDs have established an outpatient clinic for PMDs, whereas there are no inpatient psychiatric facilities designed for mothers and infants (mother-baby units)., Conclusions: There is a need to improve the care of women with PMDs in Italy. The provision of pre-conception counseling, integrated care pathways, and specialist skills and facilities for PMDs should be prioritized.
