Abstract
Background and study aims Musculoskeletal disorders (MSDs) and injuries (MSIs) are frequent in gastrointestinal endoscopy. The aim of this study was to assess potential ergonomic advantages of a lighter single-use duodenoscope compared with a standard reusable one for endoscopists performing endoscopic retrograde cholangiopancreatography (ERCP). Methods Three experienced endoscopists performed an ergonomic, preclinical, comparative protocol-guided simulation study of a single-use and a standard reusable duodenoscope using an anatomic bench model. Surface EMG signals from left forearm and arm muscles were recorded. A commercial inertial sensor-based motion capture system was applied to record body posture as well. Results A significant lowering of root mean square amplitude and amplitude distribution of biceps brachii signal (ranging from 13% to 42%) was recorded in all the participants when using a single-use duodenoscope compared with a reusable one. An overall reduction of muscle activation amplitude and duration was also associated with the single-use duodenoscope for forearm muscles, with different behaviors among subjects. Participants spent most of the time in wrist extension (> 80%) and ulnar deviation (> 65%). A consistent pattern of functional range of motion employed for completing all procedures was observed. Conclusions Our study showed that a lighter scope has a promising effect in reducing upper arm muscle activity during ERCP with potential benefit on musculoskeletal health in the ERCP setting.

Abstract
Abstract
Background
The coexistence of cardiac amyloidosis (CA) and degenerative aortic stenosis (AS) is increasing but the diagnosis is challenging because these two conditions share a common echocardiographic phenotype (1). Different predictors have been proposed in the last few years, including clinical, ECG-graphic and echocardiographic features (2–3).
Purpose
To identify a new marker of concomitant CA in patients with severe AS analyzing computed tomography scan (CT).
Methods
55 patients with severe AS and suspicion of concomitant CA were retrospectively enrolled. Patients with a bicuspid aortic valve, previous aortic valve replacement, or an incomplete diagnostic workup for CA were excluded. 33 patients underwent CT-scan and were included in the final analysis.
Results
None of the patients presented laboratory suspicion for AL amyloidosis; 12 patients (AS-CA) had positive 99m Tc-DPD bone scintigraphy (two with visual score 1, eight score 2 and two score 3), 21 patients (AS-alone) had negative bone scintigraphy. AS-CA patients had a median age of 85,5 years (versus 81,5) with only one female patient (versus 8 in the AS-alone group). AVA indexed were comparable between AS-CA and AS-alone groups (0,4 versus 0, 3 mm2/m2, p: 0.25). Stroke volume evaluated by pulsed Doppler, maximum and mean gradient were significatively lower in AS-CA group (respectively 30 versus 41 ml/m2, p: 0.017, 62 versus 74 mmHg, 0.038 and 33 versus 46 mmHg, p:0.022) with a higher percentage of low flow-low gradient aortic stenosis in AS-CA group (7 patients, 58% vs 3 patients in AS-alone 14%, p: 0.027), in line with the literature. ECG at first presentation in AS-CA group showed atrial fibrillation in 8 patients (67%), versus 2 patients in the AS-alone group (10%), and lower QRS voltages (peripheral QRS score 40 mV vs 51 mV, p-value:0.017; total QRS score 113 mV versus 155 mV, p-value: 0.005). The echocardiogram showed a more thickened IVS and PW in AS-CA patients (17 versus 15 mm, p: 0.05 and 15 versus 14 mm, p: 0.013), an augmented left ventricular mass (441 versus 356 g, p: 0.036) with a decreases longitudinal systolic function (septal S wave at TDI 4.4 versus 5.2 cm/s, p: 0.026, lateral S wave 4.1 versus 5.6 cm/s, p: 0.024) and a reduction in myocardial contraction fraction (12 versus 14%, p: 0.036).
CT- aortic valve calcium was quantified by an experienced operator. A statistically significant difference between AS-CA and AS-alone groups was observed in calcium score (3345 versus 4785 Hounsfield units, p: 0.037) calcium volume (2411 versus 3626 mm2, p: 0.03) and calcium mass (687 versus 1147 g, p: 0.023)
Conclusions
This study is the first to our knowledge to use relative aortic valve calcium score evaluation from CT imaging to characterize patients with severe AS with or without concomitant CA in addition to the classical clinical, ECG graphic, echocardiographic parameters. CT-aortic valve calcium burner was significatively lower in patients with concomitant CA.

Abstract
Abstract
Background
Hereditary transthyretin-related amyloidosis (h-ATTR) is a systemic infiltrative disease caused by a single amino acid mutation on the transthyretin (TTR) gene, which destabilizes the protein and can determine its deposition on multiple organs, including heart and peripheral nervous system.
Purpose
We aimed to characterize and compare clinical, instrumental, and prognostic features of patients affected by h-ATTR by dividing the population into the disease's main phenotypes (unaffected carriers, cardiac, neurological or mixed phenotype).
Methods
Two hundred and eighty-five subjects of a single-centre cohort with a recognized pathogenic mutation on TTR gene were retrospectively included in the analysis. Phenotypes of disease were defined at baseline. Neurological phenotype (NP) was defined according to sensorimotor and/or autonomic dysfunction, while cardiac phenotype (CP) was defined in the presence of unexplained maximum wall thickness >12 mm and other typical echocardiographic findings. Unaffected carriers (UC) and mixed phenotypes (MP) presented none or both of the above-mentioned features, respectively.
Results
Two hundred and ten patients showed clinical signs of the disease, 37 (13%) with CP, 65 (23%) with NP and 108 (38%) with MP, while 75 subjects (26%) were UC. Ile68Leu was the most represented mutation (96 subjects, 34%), followed by Val30Met (21%) and Glu89Gln (13%). NP patients (mostly Val30Met) had mPND score >1 in 45% of patients, were younger at diagnosis (mean 47 years, p<0,001 vs CP/MP), and sex was equally distributed. In contrast, CP patients were older at diagnosis (mean 70 years, p<0,001 vs CP/MP), predominantly male (as well as in MP) with a higher incidence of tunnel carpal syndrome and a shorter time interval between onset of symptoms and diagnosis (mean 17 months, p<0,001 vs CP/MP). NYHA class, ECG findings, left ventricular wall thickness and ejection fraction did not significantly differ between CP and MP. After a mean follow-up of 59 months, 98 (34%) patients died. On a Kaplan-Meier survival analysis, mean survival times were 208, 123, 150 and 95 months for UC, CP, NP and MP, respectively, with a statistically significant difference in affected patients between NP and MP (p=0.012).
Conclusions
H-ATTR is a rare systemic disorder whose natural history, including age of onset, clinical characteristics and instrumental findings, is strongly influenced by primary phenotypes, ranging from the excellent prognosis of unaffected carriers to the inauspicious outcome of mixed phenotypes.

Elbow tendinopathy and occupational biomechanical overload: A systematic review with best-evidence synthesis. J Occup Health 2021; 63:e12186. [PMID: 33534951 PMCID: PMC7857538 DOI: 10.1002/1348-9585.12186] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 11/10/2020] [Accepted: 11/24/2020] [Indexed: 01/01/2023] Open
Abstract
OBJECTIVES To evaluate the evidence of an association between occupational and non-occupational exposure to biomechanical risk factors and lateral elbow tendinopathy, medial elbow tendinopathy, and olecranon bursitis. METHODS We carried out a systematic review of the literature. We searched MEDLINE (up to November 2019) and checked the reference lists of relevant articles/reviews. We aimed to include studies where (a) the diagnosis was based on physical examination (symptoms plus clinical signs) and imaging data (if any); and (b) the exposure was evaluated with video analysis and/or direct measurements. A quality assessment of the included studies was performed along with an evaluation of the level of evidence of a causal relationship. RESULTS We included four studies in the qualitative synthesis: two prospective cohorts and two cross-sectional studies. All the included studies investigated "lateral/medial epicondylitis", albeit the diagnosis was not supported by imaging techniques. Two cohort studies suggested that a combination of biomechanical risk factors for wrist/forearm is associated with increased risk of "lateral epicondylitis". This association was not observed in the two included cross-sectional studies. The cohort studies suggested that a Strain Index score higher than 5 or 6.1 could double the risk of "lateral epicondylitis". No association with increased risk of "medial epicondylitis" was observed. CONCLUSIONS There is limited evidence of a causal relationship between occupational exposure to biomechanical risk factors and lateral elbow tendinopathy. For medial elbow tendinopathy, the evidence is insufficient to support this causal relationship. No studies on olecranon bursitis and biomechanical overload were identified.

Abstract
Abstract
Background
While the beneficial effects of cardiac resynchronization therapy (CRT) have been widely investigated soon after CRT implantation, relatively few data are available on long-term clinical outcomes of CRT recipients.
Aim
To investigate long-term outcomes of CRT patients with non-ischemic dilated cardiomyopathy stratified as responders and non-responders according to radionuclide angiography.
Methods
Consecutive heart failure patients with non-ischemic dilated cardiomyopathy undergoing CRT implantation at our University Hospital between 2007 and 2013 were enrolled. All patients were assessed with equilibrium Tc99 radionuclide angiography at baseline and after 3 months of CRT. Left ventricular (LV) ejection fraction was computed on the basis of relative end-diastolic and end-systolic counts, and intraventricular dyssynchrony was derived by Fourier phase analysis. Response to CRT was defined by an absolute increase in LV ejection fraction (LVEF) ≥5% at 3-month follow-up. Clinical outcome was assessed after 10 years through hospital records review.
Results
Forty-seven patients (83% men, 63±11 years) were included in the study. At 3 months, 25 (53%) patients were identified as CRT responders according to LVEF increase (from 26±8 to 38±12%, p<0.001). In these patients, LV dyssynchrony decreased from 59±30° to 29±18° (p<0.001). Twenty-two (47%) patients were defined as non-responders. No significant changes in LVEF and LV dyssynchrony (50±30° vs. 38±19°, p=0.07) were observed in non-responders. At long-term follow-up (11±2 years), all-cause and cardiac mortality rates were 24% and 12% in responders vs. 32% and 27% in non-responders, respectively (p=ns). Heart transplantation was performed in 3 patients. One (4%) patient among CRT responders compared with 6 (27%) patients among non-responders died of worsening heart failure (p=0.03).
Conclusions
Although late overall mortality of non-ischemic CRT recipients was not significantly different between mid-term responders and non-responders, CRT responders were at lower risk of worsening heart failure death.

Abstract
Clinical case
A 53 years woman in good health and un uneventful clinical history except for a mild hypercholesteremia was evaluated for palpitations. At the clinical examination she had a systolic murmur 3/6 Levine, with no signs of heart failure.
The ECG showed normal sinus rhythm with a normal heart rate (62bpm), normal atrio-ventricular and intraventricular conduction and normal repolarisation, one supraventricular premature beat. The echocardiography showed normal biventricular dimension and function, no valvular heart diseases, no septal defects, regular aortic dimensions. A giant right coronary was evidenced (Figure, panel a) with an arteriovenous fistula originating from the right coronary artery and draining through the coronary sinus into the right atrium (Figure, panel b). The CT coronary angiogram evidenced an dilated right coronary artery communicating with the coronary sinus (arteriovenous fistula) draining into the right atrium. A smaller arteriovenous fistula was evidenced between the circumflex artery (slightly dilated) and the great cardiac vein. (Figure, panel c-e)
The Treadmill test didn’t evidence an induced ischemia; however the patient didn’t perform a maximal exercise (double product 20400mmHb*bpm). Moreover, during the first steps of recovery frequent supraventricular premature beats were registered with phases of bigeminies followed by a junctional rhythm phase. Thus, a Gated myocardial Perfusion SPECT was performed evidenced a mild stress induced ischemia of the inferolateral and apical left ventricle wall with normal rest perfusion and normal left ventricle volumes (125ml during exercise and 134ml at rest) with a normal ejection fraction ( > 65%). (Figure, panel f)An elective coronarography was planned. The patient is on therapy with beta-blockers and aspirin. The patient is asymptomatic for angina. Antibiotic prophylaxis was recommended for dental, gastrointestinal, or urologic procedures. Discussion: Coronary arteriovenous fistula (CAVF), first described in 1865 by Krausein (1), are a rare congenital heart disease representing less than 0.5% of all congenital heart diseases with an extremely rare prevalence 0.002% in the general population (2). Moreover, therapy of CAVF is still controversial with previous data showing a relatively high rate of myocardial infarction after surgical repair (3). The recent AHA/ACC guideline for the management of adults with Congenital heart disease recommend a review by a knowledgeable team that may include congenital or noncongenital cardiologists and surgeons to determine the role of medical therapy and/or percutaneous or surgical closure (4) Conclusion: CAVF is a very rare congenital heart defect and might be asymptomatic and evidenced by hazard in adults patients. Therapy strategy demands a multidisciplinary team evaluation and should be be individualized according to the clinic presentation, the presence or absence of myocardial ischemia or ventricular dysfunction.

Abstract
OBJECTIVE Conflicting evidence exists to what extent manual material handling (MMH) causes lumbar disc disease, lack of evidence exist that this effect takes place especially at L5-S1 level, where the greatest moment occurs. The aim was to assess if lumbar vertebral body and disc changes are more common in people whose job involves significant MMH and, if so, to evaluate if lumbar vertebral body and disc changes are more prevalent in the lower part of the lumbar spine (L4-L5 and L5-S1). DESIGN Observational, cross-sectional, with quasi-random recruitment. SETTING Outpatient radiology units of three large hospitals in northern (Bologna and Brescia) and southern (Bari) Italy. PARTICIPANTS 183 consecutive adult subjects (89 males, 94 females) aged 20-70 years referred by the general practitioner or a specialist for MRI of the lumbar spine. PRIMARY AND SECONDARY OUTCOME MEASURES Neuroradiologists (blind to clinical assessment) evaluated the prevalence of intervertebral disc and vertebral body changes in standardised MRI examinations. History of personal and family musculoskeletal diseases and injuries, current and previous MMH at work and during leisure time were assessed by interview and self-administered questionnaire. RESULTS Participants were classified according their occupational exposure to MMH. No association was found between MMH and vertebral body and intervertebral disc changes, whereas age over 45 years was consistently associated with more disc extension beyond the interspace changes, Pfirrmann changes, osteophytes and Modic changes: the association was statistically significant at the conventional 5% level. CONCLUSIONS Age, and not MMH, seems to primarily affect the presence of intervertebral disc changes; prospective studies are needed to better explore the relationship between MMH and the possible presence (and level) of lumbar vertebral body and/or disc changes.

Abstract
Objectives We aimed at assessing whether differences among males and females in carpal tunnel syndrome (CTS) epidemiology might be attributable to segregation with respect to occupational biomechanical exposures or differential access to care by sex. Methods We analysed surgically treated cases of CTS occurring among non-manual workers in Tuscany between 1997 and 2000. We conducted a Monte Carlo simulation to estimate the difference in occupational biomechanical exposures between males and females necessary to explain the observed incidence rate ratios. We also accounted for the sex-specific probability of receiving surgery after the diagnosis of CTS, as women were reported to be more likely to undergo surgery in a subset of our study population. We quantified the hypothetical biomechanical overload through the hand activity level (HAL) metric proposed by the American Conference of Governmental Industrial Hygienists. To quantify the effect of HAL on CTS risk, we assumed a prior distribution based on findings from two large cohort studies of industrial workers. Results After adjustment for the probability of receiving surgery, women showed a 4-fold incidence of CTS as compared with men. To explain this association among non-manual workers, women should have an average value of HAL at least 5 points higher. Conclusions Our analysis does not support the hypothesis that the difference in CTS incidence between males and females is entirely attributable to occupational risk factors or to differential access to surgery. The causal pathway between sex and CTS might include more determinants such as hormonal factors, anthropometric characteristics, and non-occupational exposure to biomechanical overload (e.g. household tasks).

Abstract
BACKGROUND Breast cancer survivors often perceive reduced work ability upon returning to work. OBJECTIVES To identify predictors of perceived reduced work ability following return to work among women treated for breast cancer and to describe workplace interventions and support after returning to work. METHODS A questionnaire was sent to 18-65 years-old women (no. 1578) treated for breast cancer and residing in the catchment area of the Bologna Local Health Authority between 2010 and 2012. The study population was identified through a Hospital Discharge Database. The questionnaires included items about personal characteristics, cancer and work-related factors, perceived work ability and the return to work process. A multivariable logistic regression analysis was performed to identify predictors of reduced work ability upon returning to work. RESULTS Among the 841 respondents, 503 questionnaires were evaluable. In the study, 43.5% of the respondents reported reduced work ability with respect to the pre-diagnosis period. Reduced work ability was more common in non-cohabiting (OR=1.81, 95%CI 1.10-2.98) than in cohabiting/married women, and after mastectomy (OR=2.77, 95%CI 1.26-6.11) than after breast-conserving surgery. Office staff/sales assistants and managers were less likely to report reduced work ability (OR=0.51, 95%CI 0.30-0.88 and OR=0.21, 95%CI 0.06-0.76, respectively) than labourers. Women who perceived reduced work ability reported more frequently adjustment of work assignments, consultation of an occupational physician, insufficient support from employers and colleagues and discrimination. CONCLUSIONS Reduced work ability is commonly perceived among women who return to work after treatment for breast cancer. Occupational physicians and general practitioners should be aware of a wide range of factors influencing this perception in order to facilitate a successful return to work.

Abstract
OBJECTIVES A thorough and fully application of the principles of gender mainstreaming, in accordance with the European Community guidelines, to the health and safety at work, implies the systematic review of the whole prevention from the gendered point of view. This means that both biology- and gender-based differences between male and female workers should be conceived not only as determinants of health but also as factors affecting either positively or negatively the health and safety risk prevention. In this evolutionary cultural step the role of the occupational physician is particularly important. METHODS In this paper we propose some operative tools that can concretely implement gender perspective in all the various areas of prevention, where the occupational physician has a leading, if not even exclusive, role such as risk assessment, training and health medical surveillance.

Abstract
OBJECTIVES A literature review was performed to highlight which work-related diseases express sex/gender differences in health outcomes and focus the main limits of studies in this field. METHODS The research, carried out on PubMed by specific search string, identified 4828 articles (1997-2017 period) of which 381 are eligible for review (4-22%, depending on the disease). RESULTS Among them, 68% reported sex/gender differences in health outcomes, which in most cases appear to be due to different exposure and/or work segregation rather than to biological differences. However, few studies place this assessment among the research goals and results are almost never discussed and hypothesis are seldom formulated about any observed differences. CONCLUSIONS It seems necessary to use research methodologies and study design that can detect and explain the described complexity and useful in defining appropriate preventive strategies.

Abstract
INTRODUCTION Several studies have dealt with the issue of professional risk factors and onset of knee osteoarthritis (OA). In particular, occupational epidemiological studies have provided evidence that activities resulting in biomechanical overload may be linked with an increased risk of knee OA - also among farmers. To our knowledge, no cases of knee OA among chestnut farmers have been reported in the literature. CASE REPORT We report the case of a 70-year-old Caucasian male who has worked for more than 50 years on a chestnut farm. In 2007, an X-ray and a MRI, performed after a workplace accident to his left knee, showed the presence of knee OA. His job required a range of repetitive tasks, such as squatting, kneeling, climbing, walking on sloping terrain, assuming uncomfortable postures, and lifting and carrying heavy loads for the great majority of the working day. All the aforementioned tasks are known occupational risk factors for knee OA. Regarding individual risk factors, at the time of the first diagnosis of knee OA, the worker was 64-years-old with a body mass index of 26.5 kg/m2. He reported no cases of arthritis among his relatives and no sports playing on his part. In addition, his medical history revealed the presence of two minor lumbar disc herniations and tendinitis of the long head of the biceps. CONCLUSION Considering the lack of major individual risk factors for knee OA, it is reasonable to suppose that five decades of exposure to biomechanical overload as a chestnut farmer was a relevant risk factor for the onset of the disease.

Abstract
OBJECTIVE The American Conference of Governmental Industrial Hygienists (ACGIH) proposed a method to assess the hand, wrist and forearm biomechanical overload based on exertions frequency (hand-activity level) and force use (normalized peak force). We applied the ACGIH threshold limit value (TLV)® method to a large occupational cohort to assess its ability to predict carpal tunnel syndrome (CTS) onset. METHODS A cohort of industrial and service workers was followed-up between 2000 and 2011. We investigated the incidence of CTS symptoms and CTS confirmed by nerve conduction studies (NCS). We then classified exposure with respect to action limit (AL) and TLV. Cox regression models including age, gender, body mass index, and presence of predisposing pathologies were conducted to estimate hazard ratios (HR) of CTS and population attributable fractions. RESULTS We analyzed data from 3131 workers [females, N=2032 (65%); mean age at baseline 39.3, standard deviation (SD) 9.4 years]. We observed 431 incident cases of CTS symptoms in 8000 person-years and 126 cases of CTS confirmed by NCS in 8883 person-years. The ACGIH TLV® method predicted both CTS symptoms [HR between AL and TLV 2.18, 95% confidence interval (95% CI) 1.86-2.56; above TLV 2.07, 95% CI 1.52-2.81] and CTS confirmed by NCS (HR between AL and TLV 1.93, 95% CI 1.38-2.71; above TLV 1.95, 95% CI 1.27-3.00). About one third of CTS cases were attributable to exposure levels above the AL. CONCLUSIONS The ACGIH TLV® method predicted the risk of CTS, but the dose-response was flat above the AL; a fine-tuning of the proposed thresholds should be considered.

Abstract
Peripheral nerve injuries have the potential to cause significant disability and can be commonly associated with recreational and occupational activities. Acute nerve injuries are mainly related to violent trauma, while repeated mechanical trauma due to external forces or repetitive motions can produce chronic nerve compression injury. This chapter will present a narrative review of the existing evidence of the association between peripheral compressive nerve disorders and work-related risk factors. Carpal tunnel syndrome (CTS) is the most common peripheral neuropathy in the general population and in working populations employed in manual repetitive and forceful activities. The work-relatedness of CTS is essentially based on epidemiologic evidence and the results of experimental studies showing the capability of repetitive wrist extreme postures, associated with hand-wrist forceful exertions, to increase the pressure inside the carpal tunnel and to compress the median nerve. Assembly industry, food processing and packaging, hand-arm vibrating tools, and jobs involving high-repetition, high-force tasks put workers at risk for CTS. Less strong evidence exists of the association between ulnar elbow neuropathy and manual tasks or repetitive stretch on squatting and peroneal nerve neuropathy at the fibular head. Very few reports are available about the association between occupation and other compressive peripheral nerve injuries.

Abstract
PURPOSE To investigate how psychosocial factors (such as job demands and work-family conflict) produce absenteeism in the workplace, using the health impairment process of the job demands-resources model. According to this model, job demands lead to burnout (often measured with the emotional exhaustion component), which in turn could lead to outcomes (such as absenteeism). Work-family conflict (WFC) was also studied, because of contradictory results collected in the existing literature on absenteeism in the workplace, regarding the role of WFC in causing absenteeism. METHODS Data were collected on 245 workers using both subjective (questionnaire on psychological risk factors and work-related health) and objective data (sickness leave frequency records). To test the hypothesis that job demands and WFC contribute to absenteeism in the workplace, a subsequent mediation analysis was used, which analysed both (a) the subsequent mediation of WFC and emotional exhaustion and (b) the separate roles played by the mediators proposed (WFC and emotional exhaustion). RESULTS Job demands affect absenteeism through the subsequent mediation of WFC and emotional exhaustion. In addition, emotional exhaustion mediates the relationship between job demands and absenteeism, while WFC does not. CONCLUSION In conclusion, subsequent mediation highlights the role of emotional exhaustion in causing absenteeism; in fact, when emotional exhaustion is included in the analysis, job demands are associated with higher levels of absenteeism. The results of this study suggest that without the concurrent contribution of emotional exhaustion, WFC does not influence absenteeism in the workplace. Our findings are useful for organizations that aim to reduce absenteeism.

Abstract
The immune system, in cooperation with neuroendocrine functions, defends from cancer and infections mainly by the activity of blood natural killer (NK) cells. Blood NK activity may be influenced by the type of employment since work is the central part of life; moreover, job stress is a situation affecting both neuroendocrine and immune systems. This study examines anxiety (by STAI 1 and 2), job strain (by the Karasek's JCQ) and blood NK activity (by an in vitro radio-isotopic method) of 134 male workers. These men, over 38 years old with stable employment, were working in factories, in construction yards, in offices, as hospital attendants or as self-employed craftsmen. Workers in factories and in construction yards, with high job strain, showed lower NK activity, while office employees, with low job demand, and craftsmen with low anxiety and elevated decision latitude, showed higher NK activity; the level of NK activity of the hospital attendants was between the other groups. In conclusion, this study confirms that the type of employment, related to job stress, affects blood NK activity. Moreover, blood NK activity may be used in the bio-monitoring of workers at high risk.

Abstract
UNLABELLED Risk assessment for upper extremity work related muscoloskeletal disorders by applying six methods of ergonomic: a ten years experience. The objective of this research was to verify and validate the multiple step method suggested by SIMLII guidelines and to compare results obtained by use of these methods: Washington State Standard, OCRA, HAL, RULA, OREGE and STRAIN INDEX. METHODS 598 workstations for a total of 1800 analysis by different methods were considered, by adopting the following multiple step procedure: prelinminary evaluation by Washington State method and OCRA checklist in all the working stations, RULA or HAL as first level evaluation, OREGE or SI as second level evaluation. RESULTS The preliminary evaluation resulted negative (risk absent) in the 75% of examined work stations and by using checklist OCRA optimal-acceptable condition was found in 58% by HAL in 92% of analysis, by RULA in 100%, by OREGE in 64%; by SI in 70% of examined working positions. We observed similar evaluation of strain among methods and main differences have been observed in posture and frequency assessment. DISCUSSION AND CONCLUSION The preliminary evaluation by State of Washington method appears to be an adequate instrument for identify the working condition at risk. All the adopted methods were in a good agreement in two estreme situations: high risk or absent risk, expecially in absent risk conditions. Level of accordance varied on the basis of their rationale and of the role of their different components so SIML indications about the critical use of biouzechanical methods and about the possible use of more than one of them (considering working chlaracteristics) have been confirmed.

Abstract
The ageing workforce is one of the major issues in Europe. Ageing has an important effect on work ability, especially in manual jobs where physical demand is high. Musculoskeletal disorders are the most common health problems among European workers and are able to affect work ability. In order to increase the employment rate of people aged 45-65, measures to sustain work ability and proper age management should be promoted: return to work strategies include adjustment of the job to the worker's health conditions and abilities. The contribution of health surveillance.programs in the management of workers affected by musculoskeletal disorders is discussed.

Abstract
Shoulder disorders due to overexertion include joint and soft tissues chronic conditions and are an important cause of disability. Shoulder pain is one of the most common musculoskeletal disorders and has been associated to manual handling of heavy loads, high repetition jobs, exposure to hand-arm vibration and to overhead activities. Diagnosis of shoulder disorders is primarily based on clinical examination; selected cases should be referred to an orthopedic specialist and to imaging. Return to normal activities should be encouraged.

Abstract
AIM This work provides an overview of the spectrum of possible occupational risk factors in the retail grocery store/supermarket workplace. METHOD Literature on this theme, obtained consulting PubMed database and Google Scholar, was checked. We also exjlore results from the National bInstitute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA). RESULTs: Contacts with objects, use of dangerous equipment (cutter, food slicer) and falls to the same level (slips, trips and falls) are the mainly described workplace hazards. Exposure to chemical (flour dust, components of detergents or disinfectants, volatile organic compounds and contact with nickel) and physical agents (cold exposure, nonionizing radiation and whole bpdy vibration) are reported by many authors. Relations between biomechanical and ergonomic risk factors and musculoskeletal disorders represent the main subjects of study. Few studies are found about biological agents (particularly among butchers). Data regarding psychosocial risks factors in this setting are still limited. CONCLUSIONS Musculoskeletal disorders continue to be the most recurrent health problem between the grocery store workers (particularly low back pain and carpal tunnel syndrome among cashiers). Many technical documents and international Srecommendations are present to prevent these kinds of disorders. Psychosocial risk factors and risk of workplace violence should deserve further investigation.

Abstract
Dichloromethane is a widely used organic solvent. Occupational exposure to dichloromethane is frequent and can result in both acute and chronic toxicity, affecting mostly the central nervous system, directly or through its metabolite, carbon monoxide. The effects of dichloromethane on the peripheral nervous system are debated. Here we report the case of a 37-year-old woman who was accidentally exposed to dichloromethane. In the days following the incident she experienced bilateral hypoacusis. Hearing loss regressed after 25 days treatment with hyperbaric oxygen. This is the first report of sudden hearing loss after acute exposure to dichloromethane, suggesting a possible toxic effect of this solvent on the auditory system.

Abstract
BACKGROUND A large number of studies have investigated the motivation behind health care workers (HCWs) taking the influenza vaccine. But with the appearance of pandemic influenza, it became important to better analyse the reasons why workers get vaccinated against seasonal and/or pandemic influenza. METHODS Three main categories of reasons were identified with an Exploratory Factor Analysis. An analysis of variance (ANOVA) was used to verify the existence of differences between three categories of choices (taking of seasonal and pandemic vaccine, only the seasonal vaccine or none). In addition, a multinomial logistic regression analysis was performed to analyse the association between stated intentions and update of seasonal and pandemic vaccine. Questionnaires were returned from 168 HCWs (67.3% women). RESULTS The results showed that age and being well-informed about vaccination topics are the most important variables in determining the choice to take the vaccine. CONCLUSIONS The results highlight the importance of enhancing education programs to improve awareness among HCWs concerning the benefits of taking the influenza vaccination, with particular attention paid to younger workers.

Abstract
BACKGROUND Low Back Pain (LBP) is a very common disorder in hospital workers. Several studies examined the efficacy of multimodal interventions for health care providers suffering from LBP; nevertheless their results did not appear to be consistent. OBJECTIVE The aim of the study was to determine the effect of a multimodal group programme (MGP) on pain and disability in a sample of hospital workers with persistent LBP. METHODS A prospective cohort study was conducted to compare baseline measurements with changes over an eight-month period. The study focused on 109 workers suffering from persistent LBP with or without radiating pain. 62 nurses and 47 blue collars not involved in health care. The MGP consisted of six group sessions including supervised exercises, an at-home programme and ergonomic advice. The primary outcome measurement was the level of disability recorded with the Roland & Morris Disability Questionnaire, while the secondary outcome measurement was the evaluation of lumbar physical discomfort with the Visual Analogue Scale. Data were analyzed using the Multiple Imputation method for dropouts. RESULTS At the short-term follow-up participants showed a statistically significant reduction (from baseline) of all outcome measurements, particularly for the nurses group. Moreover, about a third of the subjects showed clinically significant improvement. No significant reduction in pain and disability (from baseline) was observed at the mid-term follow-up in either group. CONCLUSIONS An MGP dedicated to hospital workers seems to be partially useful only for short-term follow-up, particularly for health care providers.

Abstract
OBJECTIVES People who handle antineoplastic drugs, many of which classified as human carcinogens by International Agency for Research on Cancer, are exposed to low doses in comparison with patients; however, the long duration of exposure could lead to health effects. The aim of this work was to evaluate DNA damage in white blood cells from 63 nurses who handle antineoplastic drugs in five Italian hospitals and 74 control participants, using different versions of the Comet assay. METHODS Primary DNA damage was assessed by using the alkaline version of the assay on leucocytes, whereas to detect DNA oxidative damage and cryptic lesions specifically, the Comet/ENDO III assay and the Comet/araC assay were performed on leucocytes and lymphocytes, respectively. RESULTS In the present study, no significant DNA damage was correlated with the work shift. The exposed population did not differ significantly from the reference group with respect to DNA primary and oxidative damage in leucocytes. Strikingly, in isolated lymphocytes treated with araC, lower data dispersion as well as a significantly lower mean value for the percentage of DNA in the comet tail was observed in exposed participants as compared with the control group (p<0.05), suggesting a potential chronic exposure to crosslinking antineoplastic drugs. CONCLUSIONS Although stringent rules were adopted at national and international levels to prevent occupational exposure to antineoplastic drugs, data reported in this study support the idea that a more efficient survey on long-lasting exposures at very low concentrations is needed.

Abstract
Background Stress evaluation is a field of strong interest and challenging due to several methodological aspects in the evaluation process. The aim of this study is to propose a study protocol to test a new method (i.e., the Stress Assessment and Research Toolkit) to assess psychosocial risk factors at work. Design This method addresses several methodological issues (e.g., subjective vs. objective, qualitative vs quantitative data) by assessing work-related stressors using different kinds of data: i) organisational archival data (organisational indicators sheet); ii) qualitative data (focus group); iii) worker perception (questionnaire); and iv) observational data (observational checklist) using mixed methods research. In addition, it allows positive and negative aspects of work to be considered conjointly, using an approach that considers at the same time job demands and job resources. Discussion The integration of these sources of data can reduce the theoretical and methodological bias related to stress research in the work setting, allows researchers and professionals to obtain a reliable description of workers’ stress, providing a more articulate vision of psychosocial risks, and allows a large amount of data to be collected. Finally, the implementation of the method ensures in the long term a primary prevention for psychosocial risk management in that it aims to reduce or modify the intensity, frequency or duration of organisational demands.

Abstract
BACKGROUND: Robbery in workplaces represents a potentially traumatic experience for workers. OBJECTIVES: This article describes the set up and evaluation of a comprehensive psychological intervention designed to help to reduce the adverse consequences of bank robberies. PARTICIPANTS: The study population was selected among the employees of two Italian banks.METHODS: The psychological protocol was designed according to the results of a comprehensive non-systematic review of the scientific literature and it was evaluated at work site. RESULTS: The protocol consists of a "pre-event" formative intervention and "post-event" psychological support. The qualitative data collected allowed us to understand that the reactions after a robbery can differ depending on the phase during which the workers were exposed to the robbery. We noted that the main consequences can be classified in emotional/sentimental reactions, behavioral reactions, physiological reactions and experiences during the event; emotions/feelings following the robbery and psycho/physical state and emotions/feelings in the following days.CONCLUSIONS: In a working environment, the chance to take advantage of a specific protocol for the traumatic event of a bank robbery offers both the company and the workers important tools for well-being, including post-robbery psychological support and classroom instructions.

Abstract
OBJECTIVE The present study investigates the role of boredom within the Job Demands-Resources model. Although empirical evidence suggests that the incidence of boredom at work is widespread, the study of job boredom remains neglected today. PARTICIPANTS Data were collected from 269 mass-retail workers, by means of structured face-to-face interviews. METHODS Results of multiple mediation analyses partially supported our hypotheses. RESULTS Boredom mediates the relationship between transformational leadership, low learning opportunities and general dysphoria, while work engagement mediates the relationship between transformational leadership, low learning opportunities and job satisfaction as well as general dysphoria. CONCLUSIONS Taken together, our results confirm the suitability of conceptualizing boredom within the JD-R model and contribute to the ongoing conceptualization of both the boredom literature and the JD-R literature.

Abstract
OBJECTIVES This study aimed to evaluate the risk of musculoskeletal disorders to the hand-wrist system. The American Conference of Governmental Industrial Hygienists (ACGIH) proposed threshold limit values (TLV©) based on hand activity level (HAL) and normalized peak force (PF). We validated ACGIH TLV© in OCTOPUS, a large cohort study on carpal tunnel syndrome (CTS). METHODS Industrial and service workers were followed from 2000-2003. We classified subjects with respect to action limit (AL) and TLV. Case definitions were: (i) self-reported symptoms; and (ii) combination of symptoms and positive nerve conduction studies. Poisson regression models including age, gender, body mass index, and presence of predisposing pathologies were conducted to estimate incidence rate ratios (IRR) of CTS. RESULTS There were 4097 eligible workers. Of these, 236 (5.8%) were non-responders, 2194 (53.6%) had a complete follow-up, 728 (17.8%) were lost after intermediate assessment, and 939 (22.9%) were lost after baseline. Among the 3860 subjects with complete information at baseline, 2599 (67.3%) were women [mean age 38.1 [standard deviation (SD) 9.5] years; mean body mass index (BMI) 23.8 (SD 3.9) kg/m2]. ACGIH TLV© classification predicted both CTS symptoms [IRR between AL and TLV 2.43 [95% confidence interval (95% CI) 1.77-3.33]; above TLV 3.32 (95% CI 2.34-4.72)] and CTS confirmed by nerve conduction studies [IRR between AL and TLV 1.95 (95% CI 1.21-3.16); above TLV 2.70 (95% CI 1.48-4.91)]. CONCLUSIONS We found a dose-response relationship between ACGIH TLV© classification and risk of CTS. The increased risk observed for workers exposed between AL and TLV suggests that the current AL and TLV might not be sufficiently protective.

Such prevention can take different forms (primary, secondary and tertiary), occur at different levels (i.e. in a clinical setting, at the workplace, at national level) and involve several types of activities. Members of the Scientific Committee (SC) on MSDs of the International Commission on Occupational Health (ICOH) and other interested scientists and members of the public recently discussed the scientific and clinical future of prevention of (work-related) MSDs during five round-table sessions at two ICOH conferences (in Cape Town, South Africa, in 2009, and in Angers, France, in 2010). Approximately 50 researchers participated in each of the sessions. More specifically, the sessions aimed to discuss new developments since 1996 in measures and classification systems used both in research and in practice, and agree on future needs in the field. The discussion focused on three questions: At what degree of severity does musculoskeletal ill health, and do health problems related to MSDs, in an individual worker or in a group of workers justify preventive action in occupational health? What reliable and valid instruments do we have in research to distinguish 'normal musculoskeletal symptoms' from 'serious musculoskeletal symptoms' in workers? What measures or classification system of musculoskeletal health will we need in the near future to address musculoskeletal health and related work ability? Four new, agreed-upon statements were extrapolated from the discussions: 1. Musculoskeletal discomfort that is at risk of worsening with work activities, and that affects work ability or quality of life, needs to be identified. 2. We need to know our options of actions before identifying workers at risk (providing evidence-based medicine and applying the principle of best practice). 3. Classification systems and measures must include aspects such as the severity, frequency, and intensity of pain, as well as measures of impairment of functioning, which can help in prevention, treatment and prognosis. 4. We need to be aware of economic and/or socio-cultural consequences of classification systems and measures.

Abstract
INTRODUCTION Alterations in surface electromyographic (sEMG) signals of the abductor pollicis brevis muscle were evaluated in 24 non-manual workers and 40 manual workers (25 asymptomatic and 15 reporting CTS symptoms). METHODS The initial value (IV) and the normalized rate of change (NRC) of average rectified value (ARV), mean frequency of the power spectrum (MNF), and muscle fiber conduction velocity (MFCV) were calculated during contractions at 20% and 50% of maximal voluntary contraction (MVC). Neuromuscular efficiency (NME) and kurtosis of the sEMG amplitude distribution were estimated. RESULTS With respect to controls, manual workers showed higher NME, lower ARV IV, and reduced myoelectric manifestations of fatigue (lower MNF NRC for both contraction levels, and lower MFCV NRC at 50% MVC). Kurtosis at 20% MVC showed higher values in symptomatic manual workers than in the other two groups. CONCLUSIONS Kurtosis seems to be a promising parameter for use in monitoring individuals who develop CTS.

Effect of age at disease onset in the clinical profile of spondyloarthritis: a study of 1424 Brazilian patients. Clin Exp Rheumatol 2012; 30:351-357. [PMID: 22510473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2011] [Accepted: 10/25/2011] [Indexed: 05/31/2023]
Abstract
OBJECTIVES To analyse demographic and clinical variables in patients with disease onset before and after 40, 45 and 50 years in a large series of Brazilian SpA patients. METHODS A common protocol of investigation was prospectively applied to 1424 SpA patients in 29 centres distributed through the main geographical regions in Brazil. The mean age at disease onset was 28.56 ± 12.34 years, with 259 patients (18.2%) referring disease onset after 40 years, 151 (10.6%) after 45 years and 81 (5.8%) after 50 years. Clinical and demographic variables and disease indices (BASDAI, BASFI, BASRI, MASES, ASQoL) were investigated. Ankylosing spondylitis was the most frequent disease (66.3%), followed by psoriatic arthritis (18%), undifferentiated SpA (6.7%), reactive arthritis (5.5%), and enteropathic arthritis (3.5%). RESULTS Comparing the groups according to age of disease onset, those patients with later onset presented statistical association with female gender, peripheral arthritis, dactylitis, nail involvement and psoriasis, as well as negative statistical association with inflammatory low back pain, alternating buttock pain, radiographic sacroiliitis, hip involvement, positive familial history, HLA-B27 and uveitis. BASDAI, BASFI and quality of life, as well as physicians and patient's global assessment, were similar in all the groups. Radiographic indices showed worse results in the younger age groups. CONCLUSIONS There are two different clinical patterns in SpA defined by age at disease onset: one with predominance of axial symptoms in the group with disease onset ≤ 40 years and another favouring the peripheral manifestations in those with later disease onset.

Assessment of fitness for work in health care workers: biomechanical risk factors. LA MEDICINA DEL LAVORO 2012; 103:198-202.

Abstract
In current practice the assessment of fitness for work in health care workers exposed to biomechanical risk factors is often based on conventional approaches rather than on evidence-based guidelines. However, an accurate evaluation of worker's psychophysical resources compared to job demand and potential occupational risk factors is essential in order to properly assess fitness for work. The latest published guidelines on the management of patients suffering from back pain reported that the evidence-based approach can minimize the period of inactivity by encouraging return to work (and to other non-dangerous physical activities) in a relatively short period of time. As for carpal tunnel syndrome, there is no scientific evidence supporting a restriction of physical activities requiring forceful movements of the hand/wrist.

[Risk assessment of biomechanical overload of limbs and spine in workers employed on stone paving roads, using a combination of different methods]. LA MEDICINA DEL LAVORO 2012; 103:49-57.

Abstract
BACKGROUND Few data exist on the risk of musculoskeletal disorders in road paving workers, in addition methods for risk assessment of biomechanical overload of the lower limbs and the spine are also lacking. OBJECTIVES The aim of this study was to assess the risk from biomechanical overload for the whole musculoskeletal system and manual handling involved in the activity of stone paving of roads. METHODS In accordance with the guidelines of the Italian Society of Occupational Medicine and Industrial Hygiene various risk assessment methods were used. RESULTS The Washington State checklist revealed the presence of biomechanical overload of the spine in flexion. The Turin checklist showed a risk score higher than the acceptable limit for the cervical and lumbar spine and limbs (risk level similar to that obtained from the OCRA checklist for the upper limbs). The assessment of risk from manual handling of loads carried out using the NIOSH method provided a synthetic risk index whereas evaluation conducted using the Washington State method was acceptable. CONCLUSIONS Biomechanical risk assessment showed the presence of risk for use of force and awkward postures of the wrist and elbow, which agrees with literature data. The division of tasks among workers and the distribution of breaks helped to reduce the risk to an acceptable level for limbs. All methods however showed a risk for the spine. Health surveillance showed disorders of the spine in 28% of the workers and no disorders of the upper limbs, which agrees with the risk assessment.

A study protocol for the evaluation of occupational mutagenic/carcinogenic risks in subjects exposed to antineoplastic drugs: a multicentric project. BMC Public Health 2011; 11:195. [PMID: 21450074 PMCID: PMC3074546 DOI: 10.1186/1471-2458-11-195] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2011] [Accepted: 03/30/2011] [Indexed: 11/25/2022] Open
Abstract
Background Some industrial hygiene studies have assessed occupational exposure to antineoplastic drugs; other epidemiological investigations have detected various toxicological effects in exposure groups labeled with the job title. In no research has the same population been studied both environmentally and epidemiologically. The protocol of the epidemiological study presented here uses an integrated environmental and biological monitoring approach. The aim is to assess in hospital nurses preparing and/or administering therapy to cancer patients the current level of occupational exposure to antineoplastic drugs, DNA and chromosome damage as cancer predictive effects, and the association between the two. Methods/Design About 80 healthy non-smoking female nurses, who job it is to prepare or handle antineoplastic drugs, and a reference group of about 80 healthy non-smoking female nurses not occupationally exposed to chemicals will be examined simultaneously in a cross-sectional study. All the workers will be recruited from five hospitals in northern and central Italy after their informed consent has been obtained. Evaluation of surface contamination and dermal exposure to antineoplastic drugs will be assessed by determining cyclophosphamide on selected surfaces (wipes) and on the exposed nurses' clothes (pads). The concentration of unmetabolized cyclophosphamide as a biomarker of internal dose will be measured in end-shift urine samples from exposed nurses. Biomarkers of effect and susceptibility will be assessed in exposed and unexposed nurses: urinary concentration of 8-hydroxy-2-deoxyguanosine; DNA damage detected using the single-cell microgel electrophoresis (comet) assay in peripheral white blood cells; micronuclei and chromosome aberrations in peripheral blood lymphocytes. Genetic polymorphisms for enzymes involved in metabolic detoxification (i.e. glutathione S-transferases) will also be analysed. Using standardized questionnaires, occupational exposure will be determined in exposed nurses only, whereas potential confounders (medicine consumption, lifestyle habits, diet and other non-occupational exposures) will be assessed in both groups of hospital workers. Statistical analysis will be performed to ascertain the association between occupational exposure to antineoplastic drugs and biomarkers of DNA and chromosome damage, after taking into account the effects of individual genetic susceptibility, and the presence of confounding exposures. Discussion The findings of the study will be useful in updating prevention procedures for handling antineoplastic drugs.
