Exposure Assessment and Monitoring of Antiblastic Drugs Preparation in Health Care Settings: A Systematic Review.

Several antiblastic drugs (ADs) are classified as carcinogenic, mutagenic, and/or toxic for reproduction. Despite established guidelines and safe handling technologies, ADs contamination of the work environments could occur in healthcare settings, leading to potential exposure of healthcare staff. This systematic review aims to investigate the main techniques and practices for assessing ADs occupational exposure in healthcare settings. The reviewed studies unveil that workplace contamination by ADs appears to be a still-topical problem in healthcare settings. These issues are linked to difficulties in guaranteeing: (i) the adherence to standardized protocols when dealing with ADs, (ii) the effective use of personal protective equipment by operators involved in the administration or management of ADs, (iii) a comprehensive training of the healthcare personnel, and (iv) a thorough health surveillance of exposed workers. A "multi-parametric" approach emerges as a desirable strategy for exposure assessment. In parallel, exposure assessment should coincide with the introduction of novel technologies aimed at minimizing exposure (i.e., risk management). Assessment must consider various departments and health operators susceptible to ADs contamination, with a focus extended beyond worst-case scenarios, also considering activities like surface cleaning and logistical tasks related to ADs management. A comprehensive approach in ADs risk assessment enables the evaluation of distinct substance behaviors and subsequent exposure routes, affording a more holistic understanding of potential risks.

Sleep disorders and night-shift work in nursing students: a cross-sectional study.

BACKGROUND: University students are known to have higher sleep disorders prevalence than the general population. Among them, nursing students are even more susceptible to sleep disorders. This study evaluates sleep disorders' risk factors among nursing students and their potential association with symptoms and assesses whether night shifts affect sleep quality by increasing the prevalence of sleep disorders. METHODS: A total of 202 nursing students were included; a self-administered questionnaire was used to collect data on sociodemographic and academic characteristics (i.e., gender, age, height, weight, and year of nursing program) and risk factors for sleep disorders (e.g., smoking, lack of physical activity, and coffee intake late in the evening). The survey included the General Health Questionnaire to assess perceived stress, the Sleep and Daytime Habits Questionnaire, and the Epworth Sleepiness Scale to assess sleep disorders symptoms. RESULTS: A high level of perceived stress is associated with sleep disorders symptoms and with poor sleep quality. Daytime symptoms are also associated with smoking. Students who drink coffee late in the evening report fewer nighttime symptoms. Night shifts and their increasing number are not associated with sleep disorders symptoms. The perception of an unsatisfying academic performance is associated with daytime symptoms and poor sleep quality. CONCLUSIONS: Although night shifts seem to not affect sleep quality among nursing students, sleep disorders represent a critical issue in this population since sleep disorders symptoms may result in errors, accidents, or low academic performance.

Incidence of SARS-CoV-2 infection in health care workers from Northern Italy based on antibody status: immune protection from secondary infection- A retrospective observational case-controlled study.

OBJECTIVE: The protection from SARS-CoV-2 infection induced by SARS-CoV-2 anti-S1 and anti-S2 IgG antibody positivity resulting from natural infection was evaluated. METHODS: The frequency of SARS-CoV-2 infection (as determined by virus RNA detection) was evaluated in a group of 1,460 seropositive and a control group of 8,150 seronegative healthcare workers in three Centres of Northern Italy in the period June-November 2020. Neutralizing serum titers were analyzed in seropositive subjects with or without secondary SARS-CoV-2 infection. RESULTS: During the 6-month survey, 1.78% seropositive subjects developed secondary SARS-CoV-2 infection while 6.63% seronegative controls developed primary infection (odds ratio: 0.26; 95% confidence interval: 0.17-0.38). Secondary infection was associated with low or absent serum neutralizing titer (p<0.01) and was mildly symptomatic in 45.8% cases vs 71.4% symptomatic primary infections (odds ratio: 0.34; 95% confidence interval: 0.16-0.78). CONCLUSIONS: Immunity from natural infection appears protective from secondary infection; therefore, vaccination of seronegative subjects might be prioritized.

Placental features of fetal vascular malperfusion and infant neurodevelopmental outcomes at 2 years of age in severe fetal growth restriction.

BACKGROUND: Placental pathologic lesions suggesting maternal or fetal vascular malperfusion are common among pregnancies complicated by intrauterine growth restriction. Data on the relationship between pathologic placental lesions and subsequent infant neurodevelopmental outcomes are limited. OBJECTIVE: This study aimed to assess the relationship between placental pathologic lesions and infant neurodevelopmental outcomes at 2 years of age in a cohort of pregnancies complicated by intrauterine growth restriction. STUDY DESIGN: An observational cohort study included singleton intrauterine growth restriction pregnancies delivered at ≤34 weeks' gestation and with a birthweight of ≤1500 g at a single institution in the period between 2007 and 2016. Maternal and neonatal data were collected at discharge from the hospital. Infant neurodevelopmental assessment was performed every 3 months during the first year of life and every 6 months in the second year. Penalized logistic regression was used to test the association of maternal vascular malperfusion and fetal vascular malperfusion with infant outcomes adjusting for confounders. RESULTS: Of the 249 pregnancies enrolled, neonatal mortality was 8.8% (22 of 249). Severe and overall maternal vascular malperfusion were 16.1% (40 of 249) and 31.7% (79 of 249), respectively. Severe maternal vascular malperfusion was associated with an increased risk of neonatal mortality (adjusted odds ratio, 3.3; 95% confidence interval, 1.2-9.5). Among the 198 survivors after a 2-year neurodevelopmental follow-up evaluation, the rate of major and minor neurodevelopmental sequelae was 57.1% (4 of 7) among severe fetal vascular malperfusion (adjusted odds ratio, 24.5; 95% confidence interval, 4.1-146), 44.8% (13 of 29) among overall fetal vascular malperfusion (adjusted odds ratio, 5.8; 95% confidence interval, 5.1-16.2), and 7.1% (12 of 169) in pregnancies without fetal vascular malperfusion. Infants born from pregnancies with fetal vascular malperfusion also had lower 2-year general quotient, personal-social, hearing and speech, and performance subscales scores than those without fetal vascular malperfusion. Finally, in the presence of fetal vascular malperfusion, the likelihood of a 2-year infant survival with normal neurodevelopmental outcomes was reduced by more than 70% (adjusted odds ratio, 0.29; 95% confidence interval, 0.14-0.63). Noticeably, 10 of the 20 subjects with a 2-year major neurodevelopmental impairment (3 of 4 with severe fetal vascular malperfusion) had little or no abnormal neurologic findings at discharge from neonatal intensive care unit. CONCLUSION: In preterm intrauterine growth restriction, placental fetal vascular malperfusion is correlated with an increased risk of abnormal infant neurodevelopmental outcomes at 2 years of age even in the absence of brain lesions or neurologic abnormalities at discharge from the neonatal intensive care unit. In the case of a diagnosis of fetal vascular malperfusion, pediatricians and neurologists should be alerted to an increased risk of subsequent infant neurodevelopmental problems.

Evidence for managing chronic low back pain in primary care: a review of recommendations from high-quality clinical practice guidelines.

AIM: Chronic low back pain represents a major problem throughout the world which is increasing largely because of the aging world population. Clinical practice Guidelines can be powerful tools for promoting evidence-based practice, as they integrate research findings in order to support decision making. This study aimed to review recommendations for the management of Chronic low Back Pain in primary care based on high-quality recent and recently updated Clinical practice Guidelines. METHODS: CINHAL, PubMed, EMBASE, PEDro, Google Scholar, Government websites, Scientific Association websites were searched until April 2019. The retrieved documents underwent several consecutive selection steps: semi-automated duplicate screening, documents selection based on title and abstract screening. Finally, three independent investigators screened the documents for the selected inclusion criteria and reviewed the retrieved documents by means of the AGREE II instrument. RESULTS: A total of 3055 records were retrieved, of which 10 Clinical practice Guidelines met the inclusion criteria. The overall quality of these Clinical practice Guidelines was moderately variable. The recommendations of four Clinical practice Guidelines deemed as "excellent" were extracted and summarized. Although we tried to implement the most comprehensive research strategies, some Clinical practice Guidelines may be missing due to publication bias or incomplete indexing. CONCLUSIONS: This study showed a partial progress in respect of the methodological quality of the Clinical practice Guidelines. Several AGREE II domains demonstrated low scores, particularly the "applicability" and "monitoring and auditing criteria" are the domains most susceptible to amendments in future.Implications for rehabilitationClinicians should be aware that among recently published/updated clinical practice guidelines for the management of chronic low back pain in primary care only few were deemed to have high quality.Increasing evidence suggests the efficacy for self-management to improve low back pain outcome.Physical treatments are recommended in order to improve low back pain outcome while many physical modalities such as TENS, ultrasound, laser therapy are not.Psychological treatments are recommended and should be included as part of a broader treatment plan.

Occupational Risks in Midwifery: From Bernardino Ramazzini to Modern Times.

Occupational risks are often underestimated in midwifery. It is not commonly known that occupational risks were originally described by the Italian physician Bernardino Ramazzini (1633-1714) at the beginning of the 18th century. Our aim was to describe occupational risks in midwifery from Ramazzini to modern times. The original text by Bernardino Ramazzini was analyzed. A review of modern scientific articles on occupational risks in midwifery was conducted. Ramazzini identified two major occupational risks in midwifery: infections and awkward postures. Modern literature seems to agree with his considerations, focusing on infection, use of universal protection and personal protective equipment, and musculoskeletal problems. Modern studies also evidenced posttraumatic stress disorder that was probably postulated by Ramazzini himself. The poor number of articles in literature on midwives' occupational risks shows a lack of interest toward this issue. Prevention should therefore be emphasized in this field, so high-quality studies on occupational risks in midwifery are needed.

Benzene and leukemia: from scientific evidence to regulations. A historical example.

BACKGROUND: Benzene is a highly flammable, highly volatile liquid aromatic hydrocarbon. It has been used in many industrial processes as a solvent or a starting material. At the beginning of the twentieth century, it was very widely used in the workplace, especially in printing and in the shoe manufacturing and rubber industries. Although benzene was first recognized to cause aplastic anemia, its association with leukemia has been investigated only since the 1930s. In 1963, Italy was one of the first countries in the world to adopt a law to ban benzene as a solvent in work activities. OBJECTIVES: This study analyzed the contribution of the Clinica del Lavoro in Milan, Italy, to studies of the relationship between exposure to benzene and leukemia. METHODS: Scientific literature and historical sources on benzene and leukemia in the twentieth century were reviewed, and interviews with a first-hand witness of that period were conducted. RESULTS: By 1928, several scholars had reported anecdotal cases of leukemia among workers exposed to benzene. Enrico Vigliani was the first to collect all of these cases and to try to conduct statistical analysis on these data, in order to support the association between benzene and leukemia. In the 1960s, Vigliani and Alessandra Forni showed that benzene could cause chromosome aberrations in the bone marrow that could produce leukemic clones. CONCLUSIONS: As a result of these studies and the subsequent regulations which banned benzene, exposure conditions changed in the workplace in the last few decades. The resulting low concentrations have prompted researchers to investigate new exposure biomarkers and to study any related health problems.

Impact of Hanging Motionless in Harness on Respiratory and Blood Pressure Reflex Modulation in Mountain Climbers.

Harness hang syncope (HHS) is a risk that specifically affects safety of harness users in mountain climbing. Aims: To evaluate individual patterns of breathing resulting from deranged cardiovascular reflexes triggering a syncopal event when a mismatch between cerebral O2 demand and supply is present. Results: Forty healthy participants [aged 39.1 (8.2) years] were enrolled in a motionless suspension test while hanging in harness. Respiratory gas exchange values were analyzed to assess the pattern of breathing (EpInWel, respiratory elastic power) and cardiovascular parameters were monitored (BP, blood pressure). Four participants experienced HHS after 30.0 (7.6) minutes, with an early manifestation of loss of control of both a sustainable EpInWel and BP, starting after 10-12 minutes. Among the other participants, two different reactions were observed during suspension: (1) group G1 tolerated 32.7 (11.4) minutes of suspension by a favorable adaptation of the EpInWel and BP parameters and (2) group G2 showed significantly shorter time of suspension 24.0 (10.4) minutes with unfavorable increase in EpInWel and BP. Conclusions: Greater resistance to HHS occurs in people developing less marked fluctuations of both respiratory and cardiovascular reflex responses. Conversely, wider fluctuations both in control of EpInWel and BP were observed in the event of decreased suspension tolerance or in syncopal events.

Risk behaviors among Italian healthcare students: a cross-sectional study for health promotion of future healthcare workers.

BACKGROUND: Risk behaviors are frequent among young adults and they are particularly relevant when considering healthcare students. OBJECTIVES: The study is aimed to examine the prevalence of smoking, binge drinking, physical inactivity, and excessive bodyweight in a population of healthcare students attending an Italian university. METHODS: Healthcare students filled an anonymous multiple-choice questionnaire on the occasion of the occupational health visit that preceded their hospital internship. The questionnaire covered socio-demographic characteristics (including student's working status and cohabitation) and risk behaviors. We evaluated the prevalence of risk behaviors and their association with socio-demographic characteristics. RESULTS: The sample consisted of 494 students (65% women): 23.2% were smokers, 7.9% had excessive bodyweight, 35% did not practice any physical activity and 50% reported binge drinking at least once in the last 12 months. We found associations of male sex (30.5%) and being nursing students (29.9%) with smoking habit. The frequency of binge drinking was higher in men (38.4%), working students (53.9%), and among those who lived without family (50%). Physical inactivity was associated with female sex (44.2%) and living without family (57.1%). Finally, the co-presence of 2 risk behaviors or more was higher in men (36.8%), in nursing students (39.6%) and in working students (44.7%). CONCLUSIONS: Our findings regarding the prevalence of risk behaviors and their potential association with socio-demographic factors may be a clue to the definition of targeted strategies aimed at reducing of risk behaviors among healthcare students.

Ultrasonography of the shoulder: asymptomatic findings from working-age women in the general population.

[Purpose] The aim of this study was to estimate the prevalence of abnormal shoulder ultrasonographic findings in a sample of asymptomatic women. [Subjects and Methods] A secondary analysis of a cross-sectional study was performed. We recruited 305 women (aged 18-56 years). All the subjects had a structured interview screening for self-reported symptoms and underwent a shoulder ultrasonographic examination, in which both shoulders were examined. The radiologist was blinded to the clinical history of the participants. All detectable shoulder abnormalities were collected. [Results] Of the subjects, 228 (74.75%) were asymptomatic at both shoulders, and 456 asymptomatic shoulders were analyzed. Lack of uniformity (supraspinatus, infraspinatus, subscapularis, and biceps brachii long head) was found in 28 shoulders (6.14%), 19 (4.17%) on the dominant side and 9 (1.97%) on the non-dominant side. Tendinosis (supraspinatus, infraspinatus, subscapularis, and biceps brachii long head) was found in 19 shoulders (5.32%), 12 (2.63%) on the dominant side and 7 (1.53%) on the non-dominant side. Calcification and other abnormal findings were reported. [Conclusion] The most common abnormalities were calcifications within the rotator-cuff tendons and humeral head geodes; other degenerative findings were less common.

[Pre-analytical errors in blood sampling: an observational study on specimen collection technique and laboratory results]. / Gli errori preanalitici nel prelievo ematico: uno studio osservazionale sulle modalità di raccolta dei campioni e sugli esiti di laboratorio.

INTRODUCTION: Around 60-70% of diagnostic and therapeutic decisions are based on blood exams. Several errors occur during the pre-analytic phase. AIMS: of this study were: to describe nurses' behaviours in blood specimen collection; to describe prevalence and type of pre-analytical errors; to assess the association between pre-analytical errors and occurrence of unsuitable specimens. METHODS: An observational cross-sectional study was conducted by means of a structured form based on up-to-date clinical recommendations. A researcher observed nurses' behaviors during 172 blood sampling procedures in medical, surgical and emergency care settings. Unsuitable procedures were registered. RESULTS: Most behaviours were correct, however some significantly diverged from recommended practices: active and passive patient identification; respect of antiseptic solution's drying time; rapid removal of tourniquet when blood started flowing. The prevalence of unsuitable specimen reports was significantly higher when the procedure involved a small calibre vein (RP: 0.19; IC95% 0.04 - 0.98; p = 0.03) and when blood drawing was difficult (RP; 3.83; IC95% 1.63 - 9.01; p <0.001). CONCLUSIONS: The pre-analytical phase is important for the diagnostic process and safety of patients. Although some factors ­ as patients' characteristics ­ are non-modifiable, some nurses' behaviours could be improved to reduce risk of pre-analytical errors. Further studies are needed to clarify the associations between pre-analytical errors and laboratory outcomes.

Sleepwalking in Italian operas: a window on popular and scientific knowledge on sleep disorders in the 19th century.

There is little knowledge on sleepwalking in ancient times even though it is a very common condition. The aim of this report is to describe the backgrounds of medical knowledge on somnambulism in the 19th century, a key period in the development of neurosciences, by analysing its representation in two famous Italian operas: La Sonnambula by Vincenzo Bellini and Macbeth by Giuseppe Verdi. The 19th-century operas may be considered as a crossing point between the popular and intellectual world because they mirror popular answers to phenomena that were still awaiting scientific explanations. Shakespeare's play Macbeth was also considered. In Shakespeare's play and in Verdi's Macbeth, sleepwalking is looked upon as a neuropsychiatric disorder, a manifestation of internal anxiety. In La Sonnambula by Bellini, this condition is considered as common disorder that anticipates scientific theories. The analysed Italian operas provide two different views on sleepwalking, probably because they are based on texts belonging to different periods. Their examination allows one to understand the gradual evolution of theories on sleepwalking, from demoniac possession to mental disorder and sleep disease. At the same time, this analysis throws some light on the history of psychological illnesses.

Comparison of active stretching technique and static stretching technique on hamstring flexibility.

OBJECTIVES: To compare a passive and an active stretching technique to determine which one would produce and maintain the greatest gain in hamstring flexibility. To determine whether a passive or an active stretching technique results in a greater increase in hamstring flexibility and to compare whether the gains are maintained. DESIGN: Randomized controlled trial. SETTING: Institutional. PARTICIPANTS: Sixty-five volunteer healthy subjects completed the enrollment questionnaire, 33 completed the required 75% of the treatment after 6 weeks, and 22 were assessed 4 weeks after the training interruption. INTERVENTION: A 6-week stretching program with subjects divided into 2 groups with group 1 performing active stretching exercises and group 2 performing passive stretching exercises. MAIN OUTCOME MEASURES: Range of motion (ROM) was measured after 3 and 6 weeks of training and again 4 weeks after the cessation of training and compared with the initial measurement. RESULTS: After 3 weeks of training, the mean gain in group 1 (active stretching) on performing the active knee extension range of motion (AKER) test was 5.7 degrees, whereas the mean gain in group 2 (passive stretching) was 3 degrees (P = .015). After 6 weeks of training, the mean gain in group 1 was 8.7 degrees , whereas the mean gain in group 2 was 5.3 degrees (P = .006). Twenty-two subjects were reassessed 4 weeks after the cessation of the training with the maintained gain of ROM in group 1 being 6.3 degrees , whereas the maintained gain in group 2 was 0.1 degrees (P = .003). CONCLUSIONS: Active stretching produced the greater gain in the AKER test, and the gain was almost completely maintained 4 weeks after the end of the training, which was not seen with the passive stretching group. Active stretching was more time efficient compared with the static stretching and needed a lower compliance to produce effects on flexibility.
