Background: Health care workers (HCWs) are at increased risk of exposure to hepatitis B virus (HBV). The most effective prevention measure is vaccination, with a serum hepatitis B surface antibody (HBsAb) titre > 10 mIU/ml considered protective. To date, the sociodemographic and occupational characteristics related to HBV serosusceptibility and factors associated with booster hesitancy remain unclear. Therefore, this study aimed to identify factors associated with maintaining a protective HBsAb titre in a large sample of HCWs and to evaluate factors potentially associated with hesitancy towards vaccine boosters., Methods: A cross-sectional study was conducted among HCWs who underwent a health surveillance visit between 2017 and 2022. If the serum HBsAb titre was < 10 MIU/ml, a vaccine booster dose was offered. Based on their willingness to be vaccinated, employees were classified into three groups: acceptance, hesitation, and refusal. Uni- and multivariable analyses were performed to assess the association of demographic and occupational characteristics with serosusceptibility and attitudes towards vaccination., Results: A total of 1632 (27%) employees were shown to be nonimmune. A lower median age and being a physician were significantly associated with a protective HBsAb titre. A total of 706 nonimmune employees (43.3%) accepted the vaccination, 865 (53%) hesitated, and 61 (3.7%) refused. The median age of those who refused vaccination was significantly higher than that of those who hesitated and those who were vaccinated. Acceptance of vaccination was significantly higher among nurses, while nurse aides hesitated more; among nonmedical graduate staff both hesitation and refusal were higher than expected. In the multivariable analysis, higher age, female sex, and employment as an allied health care professional were shown to be significantly associated with hesitation/refusal, while being born abroad turned out to be protective., Conclusions: Our study showed that approximately a quarter of HCWs were not immune to HBV infection, and of these, more than half were hesitant towards or refused the booster dose. The risk of hesitation/refusal was higher with age in women and among allied health care staff. Based on these findings, further studies are needed to prospectively evaluate HBV seroprevalence, vaccination adherence, factors associated with hesitancy, and the effectiveness of health surveillance strategies in a high-risk population susceptible to infection., Competing Interests: Declaration of Competing Interest We have no conflict of interest to declare., (Copyright © 2024 The Author(s).

. Community as learning opportunity for nursing students: The LaVàl. project of Val Chiusella., Introduction: The new competencies required for Family and Community Nurses (FFCN) involve the ability to make a community diagnosis., Aim: To describe the steps in designing an innovative internship for university students (nurses, anthropologists, educators, sociologists etc.)., Methods: After involving the municipalities, associations and local community networks, the students were asked to enter the community, keep a diary of what they had done and observed, and the nursing students were asked to produce a report based on the synthesis of the diaries, in which they would highlight the specific features, strengths, weaknessess and potentials for development of the observed community., Results: As of 31 March 2022, 50 nursing students and 6 FFCN Master's students had thier practical training in addition to anthropology, sociology, geology an occupational therapist students. By 30 September 2022, 20 nursing students, 10 Master's and Master's degree students, are expected. 96 hours of interviews were carried out with local residents, meetings were held with 30 Associations and 40 events, meetings and assemblies, 12 meetings for Walking Groups, Adapted Physical Activity and Pilates, 70 hours of direct observation in the five pharmacies and 100 hours of debriefing, supervision and multidisciplinary discussion to rework and systematise the information acquired were conducted., Conclusions: An innovative experience of training in making community diagnosia and projects for solutions for a community is feasible. However, both the organisational and local concertation prerequisites are necessary to make these experiences possible.

Aim of the Study: Critically ill populations often have shown subtherapeutic aminoglycosides' concentrations mostly because of unavoidable changes in drug volume distribution and clearance. We present a real life prospective study evaluating plasma concentrations for once-daily dosing for amikacin and gentamycin among a population of severe burn adults., Methods: We conducted a real life prospective study on the plasma observed concentrations of amikacin and gentamycin among severe burn patients, using aminoglycoside as combination therapy. Antibiotics were prescribed at the standard doses of 15-20mg/kg/day for amikacin and 3-5mg/kg/day for gentamycin., Results: Eight patients (4 in amikacin and 4 in gentamycin groups, respectively) were enrolled in the study. All subjects were admitted for severe burns. The most common site of infection was bloodstream (5; 62.5%) and pneumonia (4; 50%). Pseudomonas aeruginosa, followed by Klebsiella pneumoniae and multi-drug resistant Acinetobacter baumannii were the most prevalent agents isolated. Amikacin and gentamycin never achieved the target peak concentration of 60mg/L and 30mg/L: in our study C max , for amikacin, was 33.1±15.6mg/L (SD), while for gentamycin was 14.3mg/L±9. C max and total body surface area have shown a strong negative correlation with borderline statistical significance (amikacin: ρ=0.922, P=0.078; gentamycin: ρ=0.937, P=0.063). At the standard dosage, the pharmacokinetic/pharmacodynamic (PK/PD) target of C max >8×highest MIC was reached for 8 (53.3%) out of 15 isolated pathogens., Conclusions: The present study found that, in a population of septic burn patients, standard doses of gentamycin and amikacin most often lead to plasma concentrations under the PK/PD target., (Copyright © 2020 Société française de pharmacologie et de thérapeutique.

Purpose: We report a case of a 30 years old Indian sailor with microcytic anemia (Hb 9.9), persistent abdominal pain, emesis, dark stool, hyperchromic urine, latent jaundice and asthenia. Lead intoxication was confirmed (blood lead value of 102 μg/dL). The patient assumed Ayurvedic medicines in the previous months. Ayurveda is an ancient form of Indian traditional popular medicine aiming to re-establish health and body function through herbal preparations, heavy metals are often added. Our purpose was to treat the patient and to establish the source of poisoning., Methods: After testing blood and urine lead concentration of other 3 crew members and analyzing over than 150 products used on the ship professional exposure was excluded. We analyzed the two Ayurvedic drugs assumed by the patient with an Inductively Coupled Plasma Mass Spectrometry. The patient underwent three chelation cycles with Calcium Disodium Ethylenediaminetetraacetic acid (EDTA) while monitoring blood and urinary lead levels., Results: The final blood lead level at discharge, after three chelation cycles, was 36.27 μg/dL. One of the two drugs contained extremely high concentrations of lead and mercury. The three different mixtures of this preparation showed lead concentrations of 12,638.54 mg/kg (Sample 2A), 23,043.02 mg/kg (Sample 2B), 21,352.97 mg/kg (Sample 2C); these levels are much higher than the highest values reported in literature for the indian soil (32 mg/kg)., Conclusions: This case and similar cases raise the safety alert on complementary and alternative medicines; Ayurvedic medicine users should be carefully informed about potential risks and signs of poisoning.
