Summary: Introduction. The relationship between Self-compassion and Post-Traumatic Stress Disorder does not appear to be investigated among health professionals, in the period of the ongoing COVID-19 pandemic. This study intends to examine it in a hospital unit, where ordinary units have been converted into units for those infected with the virus. Materials and Methods. The cross-sectional observational study was carried out at a hospital in Central Italy, proposing the self-administration of the IES-R Impact Event Stress-Revised and SCS Self-Compassion Scale to nurses. The data were collected, from 10 January to 10 February 2021, on paper; the forms were handed over to the nursing coordinators, who distributed them to the operators. Results. The convenience sample includes 60 nurses, mainly female (76.7%), with an average age of 43 years (sd = 11.9) and with a presence in service of 14.6 years (sd = 11.7). The average level on the total scale Self-compassion 3.02 (ds = 1.26); the average level of Post-Traumatic Stress Disorder is 2.4 (sd = 0.64); there is a direct correlation between the common Humanity dimension and the intrusive symptoms and the mean total level of PTSD and between the Self-Criticism dimension and the avoidance symptoms. Discussion and Conclusion. The sample shows a good level in the positive dimensions of Self-compassion and low secondary Post-Traumatic Stress Disorder. Further studies, transversal, on specific more representative samples of nurses, and longitudinal, are required to evaluate the relationship between the two variables, even in the period of COVID-19. The acquisition of a personal attitude is recommended, which increases the positive dimension of Self-compassion, for one's personal well-being in the helping profession.

Summary: Background. Needle stick injuries (NSI) are a frequent problem among the medical and nurse population: NIS can cause blood exposure pathologies like HCV or HIV. Aim of this study is to determinate an incidence rate and causes of NSI. Methods. A search was conducted on the main international databases, only studies conducted in Italian nurse are considered. Results. The incidence rate of NSI varies from 2.2 to 10.77 per 100 nurses per year. The major causes can be traced back to a large night shift, working in the operating block and in the medical departments, and the failure to use adequate devices. Conclusions. It is important to work on training, on the use of safety devices and on a better night shift.

Summary: Introduction. This study explores how a background music-listening program within residential facilities for the elderly can influence the general environment and be effective on psychological and behavioral aspects. The feasibility of this type of intervention was explored. Methods and Materials. Twenty-nine residents involved in the experiment were observed for 4 weeks in absence of a music intervention and for the same period during the experimental condition. The intervention consisted in music listening programs, designed by trained music therapists for specific objectives according to the different times of the day. Experimental and control condition effects were compared through the administration of clinical scales and observational grids. Results. The results of clinical scales showed that music listening programs reduced behavioral symptoms in 7 out of 8 people with the most severe neuropsychiatric symptoms. The observational scheme completion showed a clear improvement in all outcomes considered, with the exceptions of agitation (in the morning) and irritability (in the afternoon). Discussion. The study brings several points to attention, including the need to establish a set of criteria in music listening programs selection and administration (e.g. identification of music characteristics related to objectives and outcomes, assessment strategies, involvement of a team of professionals). Implementing evidence-based clinical practice is crucial and the highlighted results encourage the introduction of music-listening approaches as part of therapeutic interventions in elderly nursing homes.

Summary: Introduction. Nitrous oxide (N2O) is widely used to induce sedation also outside of operating rooms; there is a chance of workplace exposures for the operators engaged in the outpatient use of nitrous oxide. The aim of this research is to assess nitrous oxide exposure in gastroenterology outpatient settings. Methods. We performed an observational study marked by N2O environmental testing in a gastroenterology outpatient care; environmental research was supported by biological monitoring with urinary N2O analysis in exposed operators. The research was conducted both without and using a collective security device (NIKI mask). Results. The study was rolled out in 10 sessions of day shift procedures, totaling 4105 samples. The average N2O concentration in the environment was 27.58 (SD 1.76) and 449.59 (SD 35.29), respectively with and without NIKI Mask; the distribution of gases in the environment under investigation was not homogeneous (Anovatest P=0.001). Biological testing revealed a substantial rise in urinary concentration of 8.97 (p=0.001) between the start and the end of the shift, and the use of the NIKI-mask was effective (p=.003). Discussion. The exposure levels reported exceed the limits of 50 ppm (Italy operating rooms threshold value) as well as the value of 25 ppm (NIOSH threshold-value), indicating a significant issue in the outpatient use of N2O. Technical measures are needed to contain the occupational risk from N2O exposure outside of operating rooms; for the exposure results detected in this research, it is also evident that workers exposed to N2O must be subject to adequate health surveillance accounting for this occupational risk.

Summary: Background. Aim of our study was to measure the first responses to hypobaric hypoxia: changes in ventilation minute, heart rate, and hemoglobin saturation which are important parameters involved in the health of mine-workers at high-altitude. Material and Methods. We develop a study of parameters mentioned on Chilean miners working in an underground mine at high altitude, between 3.070 and 3.656 masl, in an unusual shift system consisting of 12-hour daily work during 4 days, and consecutive 4 resting days. The results obtained at high altitude are contrasted with the corresponding for clerks working at 800 masl. Results. Either miners who has work less than 6 months at HA as those who are exposed at their workplace to contaminants, as diesel and others, show Hemoglobin Saturation below 90%. Heart Rate increases in response to exposure to acute and/or chronic hypoxia at high altitude. Miners during their resting period at 800 masl or less show an average heart rate lower than clerks no exposed to high altitude. Average Minute Volume of miners at high altitude, on each and every day of the shift, is higher than the mean volume of clerks at 800 masl. Conclusions. The most of studied miners present acclimatization responses at high altitude in all the studied parameters. The increase in Minute Volume implies a risky condition due to the increase of inhaled toxic inherent to the production process. It appears as an urgency to study the combined effects of hypobaric at high altitude and toxics present at the underground mine.

Summary: Introduction. Malignant mesotheliomas have been observed in entertainment workers in the last decades. They have been evaluated as occupationally exposed to asbestos contained in tools used for fireproof and sound-absorbing purposes. Aim of the study. To evaluate the mortality of workers engaged in a Florentine theatre where a large quantity of asbestos was found in the '80s, put in place 20 years earlier. Methods. It is a cohort study on entertainment workers with follow-up period ranged from 1-1-1970 till 31-12-2018. Standardized Mortality Ratios (SMRs) and their 95% Confidence Intervals (95% IC) were calculated by gender and job ("manual workers" and "all other jobs"), using age and sex specific mortality rates of Tuscan population. Results. The cohort includes 826 workers (389 manual workers and 437 engaged in other jobs) engaged by the Florentine theatre between 01/01/1937 and 31/12/1990. Excesses of mortality for all causes are observed in manual workers, either males (301 cases; SMR 304,0; 95% IC 271,5-340,3) or females (86 cases; SMR 429,8; 95% IC 348,0-531,0). The group of the other workers presents deficits of mortality by all causes, cancers and cardiovascular diseases in both genders. One death for pleural cancer is observed in a manual worker. Discussion. The results are in line with previous observations in similar occupations. In the examined Florentine theatre the asbestos exposures were important only for the manual workers who worked in the technical rooms characterized by the presence of friable asbestos sprinkled and in a bad state of maintenance.

Summary: The anterior cruciate ligament (ACL) is the most commonly injured knee ligament. Currently there are two commonly used surgical procedures: middle third patellar tendon grafts (bone-patellar tendon-bone: BTB) and semitendinosus autografts or semitendinosus combined with gracilis tendon autografts (ST/G). Purpose. The aim of this study is to compare the rehabilitation results over time of amateur sportsmen who have undergone anterior cruciate ligament (ACL) reconstruction surgery by means of one of the two most commonly used procedures: middle third patellar tendon grafts (bone-patellar tendon-bone: BTB) and semitendinosus and gracilis tendon autografts (ST/G). Method. 30 subjects divided into two groups, (15 BTB and 15 ST / G), were evaluated during rehabilitation and at three follow-up periods (16 weeks, 24 weeks, 2 years). Evaluation involved clinical examination, isokinetic tests, and functional rating scales: Lysholm and IKDC. Results. The clinical evaluation resulted in the following mean values: the value of the Lysholm score was 78 in both group at 16 weeks, 91 in group A and 94 in group B at 24 weeks, 98 in group A and 99 in group B at 2 years; the value of the IKDC score was 14 in group A and 15 in group B at 16 weeks, 12 in group A and 14 in group B at 24 weeks, 14 in group A and 15 in group B at 2 years. No major complications occurred during rehabilatation Conclusions. Subjects in both groups showed good neoligament stability up to the 24-week follow up. At the 2-year follow-up the subjects of group B showed poor neoligament stability that prevented the return to the previous level of sporting activity; all the subjects with high intensity sports activity needed a greater muscle strengthening. No statistically significant differences between the two groups are seen.

Summary: Background. Ionizing Radiations (IR) are an important occupational risk factor for the potential damage that can cause to workers' health and for their presence in numerous professional settings. Health care workers (HCW) can be exposed to IR from various sources, in particular from x-rays using radiological equipment, and represent the largest group of workers occupationally at risk, despite increased regulation and protection which caused exposure to low dose radiations. The thyroid gland is one of the most sensitive organs to damage and an important target of IR, leading to functional and organic diseases. The aim of this study is to assess the variations in thyroid hormones, in a population of HCW exposed to low-dose IR. Methods. 121 individuals of the Teaching Hospital Policlinico Umberto I in Rome exposed to low-dose of IR (78 HCW, 17 Residents and 26 Radiology Technicians Students) were observed assessing serum levels of different thyroid function parameters as free triiodothyronine, free thyroxine and thyroid stimulating hormone at T1, T2 and DeltaT. Age, gender, history of thyroid diseases, BMI and smoke were analyzed as possible influencing factors using linear and multiple logistic regression analysis. Results. Analyzing TSH, fT3 and fT4 serum levels, in two different measurement (T1 and T2) and considering Delta between them, adjusting for different confounding factors, data showed no variation of TSH levels related to occupational exposure, a decrease of fT3 hormone values in HCW and residents, and an increase of fT4 in HCW. Discussion. The analysis of our results revealed that hospital occupation has an impact on thyroid hormones variations, with an increase of fT4 and a decrease of fT3 and no variations of TSH. These results are in conflict with previous studies evidences, in which both free hormones decreased with a concomitant increase of TSH. Conclusion. Exposure to low dose IR influences levels of free thyroid hormones, with no variation in TSH, which could result in a functional or organic disease. For this reason it is recommended continuous surveillance through a periodic check of all the thyroid hormones for an overall view of each HCW. However, further studies are necessary to confirm hormones trend and assess any related thyroid diseases.

Summary: TBackground. Information regarding ominous prognoses, which may cause concern and distress, should be provided carefully and cautiously, using non-traumatizing terminology, accommodating the patient's fears, and not excluding elements of hope. Goal. To analyze the difficulties of health care providers in the process of communicating bad news. Materials and Methods. An observational, cross-sectional, multicenter study was conducted from March to August 2021 among Italian Physicians and Nurses. Results. The results of the study indicate a greater participation of Nurse practitioners than Physicians, a fact that may indicate how necessary it is, to overcome the belief that the communication of bad news is of exclusive medical relevance. Among the participants in the study, about half, equal to 46.7% stated that they had no specific training, while the remainder claimed to have attended master's or higher education courses in 8.5% of cases, 23% attended conferences, while 21.8% acquired their skills through work experience. Conclusions. The communication of bad news, needs to be recognized in the same way as those procedures that characterize care itself, and for which the highest possible quality is sought.

Summary: Patient manual handling (MHP) and an increase in the average age of the healthcare workforce increase the risk of musculoskeletal disorders and diseases, leading to sickness absence. Targeted interventions, supported by management, have been proven effective for workplace safety and can lead to improved quality of care.
