Abstract Background The International Agency for Research on Cancer evaluated formaldehyde (F) as carcinogenic for human in association with Nasopharyngeal Cancer (NPC). Occupational exposure to F occurs in many industrial sectors also in those non-traditional. For example in Tuscany F was detected in a bakery where a NPC case had ever worked. Methods In this study a) A case control approach (OCCAM) was used for monitoring occupational risks based on current information sources. Three Italian Regional Operating Centres, collected NPC cases from cancer registries and/or hospital discharge records. Controls were randomly sampled from the regional health service population data. Occupational histories were available through record linkage with the social security pension database (INPS). Study results were reported by industrial sectors, area and gender. b) A specific study on F exposure was conducted in bakeries and pastry industry carrying out measurements to determine the concentration of F in specific tasks and positions. Results 717 cases linked with INPS database. Increased ORs for several industrial sectors such as iron and steel, wood and plastic were observed. In two regions also health and veterinary services and hairdressers were at increased risk, but based on few cases of exposed workers. In the non traditional sector of bakeries and pastry industries, where workplaces were monitored, high levels of F in personal air samplings were found, in particular in processes that involve a strong leavening. Conclusions Many productive sectors, in which F exposure could occurred, were observed to be at higher risk. The measurements performed in the non traditional sector monitored, confirmed the F exposure in some phases of the work process. With this study we contributed to increased knowledge on the risk of NPC within the monitoring system of occupational risks, and to deepen exposure to F in a non traditional productive sector such as bakeries and pastry industries. Key messages The epidemiological method used (OCCAM) in this study provides further information on the role of occupational exposure in the development of nasopharyngeal cancer. The measurements performed in the bakeries and pastry industries provide new additional information on the exposure to formaldehyde in some work process phases of a non-traditional productive sector.

Staging Systems

Background and context: Although the TNM stage schema has been the traditional means to classify anatomic extent of disease, in recent years confusion and uncertainty have emerged which underpinned by lack of familiarity concerning underlying rules of staging and their application. In turn such lack of clarity has led increased risk of miscommunication regarding patient care, research, cancer surveillance, epidemiology and cancer control. The UICC TNM Committee has confirmed a lack of uniformity in the application of cancer stage and its rules. In addition to stage, numerous other factors influence the outcome of patients as relate to tumor characteristics, patient descriptors, and the environment where any treatment is administered. A particularly a frequent problem is mixing disease extent and biology which has promoted additional misunderstanding about the importance and relevance of different individual prognostic elements and to what degree biology vs disease burden contribute to outcome. Aim: To ensure uniformity of staging systems, rules and classifications, the TNM Committee developed a global consensus on cancer staging. Strategy/Tactics: A selected literature review of twelve high impact oncology journals was performed and results will be summarized. There was inconsistent understanding and use of cancer stage classification terminology evident in up to 20% of the literature. A survey was developed and found that only 12.5% of those surveyed thought that the application of the TNM staging terminology was consistent and uniform in the literature. Respondents believed that complete T, N and M data should be recorded in cancer registries, 71% considered that other predictive and prognostic factors should also be collected by central cancer registries but that anatomic disease extent should be collected as a separate variable (85%). The Global Consultation on Cancer Staging was held under the auspices of the Union for International Cancer Control (UICC) and Lancet Oncology with support from the United States (US) National Cancer Institute (NCI) and the US Centers for Disease Control and Prevention (CDC). Experts from these organizations and FIGO (Fédération Internationale de Gynécologie et d´Obstétrique), IACR (International Association of Cancer Registries), IARC (International Agency for Research in Cancer), and the ICCR (International Collaboration on Cancer Reporting) attended. Program/Policy process: The purpose of the staging classification was reaffirmed. Important issues about staging processes were annunciated, and inconsistencies in terminology and use were acknowledged. Definitions of frequently misused staging terms were clarified. What was learned: It was determined that methodologies need to be explored to identify and include necessary data elements relevant to personalized treatment. Selection of factors should particularly include attention to their inclusion in cancer registries where appropriate.

SummaryOsteoporosis in men is increasingly recognized as an important public health problem but affected patients are still under-diagnosed and -treated. As in women the diagnostic and therapeutic strategy has to be adapted to the individual case. In the practical management it is very important to detect possible causes of secondary osteoporosis, to explain the possibilities of basic therapy counteracting individual risk factors and communicate that osteoporosis is a chronic disease and adherence to a long-term treatment is crucial. In established severe osteoporosis a careful analgesic therapy is important to avoid further bone loss related to immobility. In elderly men with increased risk of falling insufficient Vitamin D supply or impaired activation of Vitamin D due to renal insufficiency must be taken into consideration. Specific medications available today for the treatment of male osteoporosis comprise among antiresorptive drugs the bis phosphonates alendronate, risedronate and zoledronic acid. Denosumab, the first biological therapy is approved for men with androgen deprivation therapy for prostate cancer. An important advantage of this potent antiresorptive drug is the increased adherence due to the comfortable application by sixmonthly subcutaneous injections. Study results from the 2-year multi-center randomized controlled ADAMO-Study will very soon allow the use of denosumab in all types of male osteoporosis. Teriparatide, the 34 N-terminal amino acid sequence of parathyroid hormone was approved for men with osteoporosis as an anabolic agent based on proven efficacy by different studies. Among drugs with other modes of action the D-hormone pro-drug alfacalcidol can be used in men alone or in combination with the advantage of pleiotropic effects on calcium absorption, parathyroids, bone and muscle. Recently also Strontium-ranelate was approved for male patients with the limitation to exclude men with clinical relevant cardiovascular risk factors. In general the possibilities to treat male osteoporosis have considerably improved during recent years. Today there is a choice of a spectrum of drugs from mild to strong potency with different modes of action on bone turnover to design strategies for individual male patients.

Occupational Settings

Regarding the widely distribution of respiratory exposure hazards in occupational settings, workers have an increased risk for chronic lung diseases. For assessing the quality of life and lung function in workers exposed to chemicals and dust, St George�s Respiratory Questionnaire (SGRQ) and spirometry were performed among 40 patients, admitted in Occupational Clinic Department of Colentina Hospital, Bucharest, Romania, during February, 2017. SGRQ showed different predictors for patients according to their occupational exposure and total symptoms score correlated better with decreased spirometric parameters in defining lung function deterioration. Quality of life is earlier affected than lung function deterioration and emphasises the need of more sensitive methods for an earlier identification and better evaluation of respiratory hazards in different workplaces.

This chapter describes occupational and environmental liver disorders. It describes the types of liver function and types of liver damage, and how these functions and this damage can be assessed. Workers in healthcare and solid waste management are at increased risk hepatitis B virus and hepatitis C virus infections. Occupational exposure to swine is associated with hepatitis E virus infection. More than 100 industrial chemicals can be acutely hepatotoxic in experimental animals or humans. Metabolic reactions may affect the hepatotoxicity of chemicals. Occupational exposure to organic solvents can cause toxic hepatitis. Occupational exposure to vinyl chloride monomer has been causally associated with toxicant-associated fatty liver disease as well as a form of non-cirrhotic portal hypertension. Several agents can cause cancer of the liver or bile ducts. Vinyl chloride monomer is causally associated with angiosacoma of the liver. Arsenic causes liver cancer. Dietary exposure to aflatoxins can cause hepatoceulluar carcinoma.

AbstractThe SARS-Cov-2 pandemic in 2020 has caused oncology teams around the world to adapt their practice in the aim of protecting patients. Early evidence from China indicated that patients with cancer, and particularly those who had recently received chemotherapy or surgery, were at increased risk of adverse outcomes following SARS-Cov-2 infection. Many registries of cancer patients infected with SARS-Cov-2 emerged during the first wave. We collate the evidence from these national and international studies and focus on the risk factors for patients with solid cancers and the contribution of systemic anti-cancer treatments (SACT—chemotherapy, immunotherapy, targeted and hormone therapy) to outcomes following SARS-Cov-2 infection. Patients with cancer infected with SARS-Cov-2 have a higher probability of death compared with patients without cancer. Common risk factors for mortality following COVID-19 include age, male sex, smoking history, number of comorbidities and poor performance status. Oncological features that may predict for worse outcomes include tumour stage, disease trajectory and lung cancer. Most studies did not identify an association between SACT and adverse outcomes. Recent data suggest that the timing of receipt of SACT may be associated with risk of mortality. Ongoing recruitment to these registries will enable us to provide evidence-based care.

Kidney Replacement Therapy

Objective: Continuous kidney replacement therapy (CKRT) is the primary therapeutic modality utilized in hemodynamically unstable patients with severe acute kidney injury. As the circuit is extracorporeal, it poses an increased risk of blood clotting and circuit loss; frequent circuit losses affect the provider’s ability to provide optimal treatment. The objective of this meta-analysis is to evaluate the safety and efficacy of the extracorporeal anticoagulants in the pediatric CKRT population. Data Sources: We conducted a literature search on PubMed/Medline and Embase for relevant citations. Study Selection: Studies were included if they involved patients under the age of 18 years undergoing CKRT, with the use of anticoagulation (heparin, citrate, or prostacyclin) as a part of therapy. Only English articles were included in the study. Data Extraction: Initial search yielded 58 articles and a total of 24 articles were included and reviewed. A meta-analysis was performed focusing on the safety and effectiveness of regional citrate anticoagulation (RCA) vs unfractionated heparin (UFH) anticoagulants in children. Data Synthesis: RCA had statistically significantly longer circuit life of 50.65 hours vs. UFH of 42.10 hours. Two major adverse effects metabolic alkalosis and electrolyte imbalance seen more commonly in RCA compared to UFH. There was not a significant difference in the risk of systemic bleeding when comparing RCA vs. UFH. Conclusion: RCA is the preferred anticoagulant over UFH due to its significantly longer circuit life, although vigilant circuit monitoring is required due to the increased risk of electrolyte disturbances. Prostacyclin was not included in the meta-analysis due to the lack of data in pediatric patients. Additional studies are needed to strengthen the study results further.

ObjectiveThis article explores the impact of regulations on the implementation of collective protections in France to occupational exposure to carcinogenic, mutagenic and reprotoxic (CMR) agents.MethodsIndividual data from the French national cross-sectional survey of occupational hazards conducted in 2010 were analysed. We investigated whether stricter regulations and longer exposures were associated with higher level of collective protection using multivariate logistic regressions.ResultsGeneral ventilation, for which effect is limited as collective protection for CMR products, was present in 19% of situations involving CMR agents while isolation chambers, the most effective form of protection, were only very rarely implemented. Multilevel logistic regressions show that exposure situations to products classified as category 1 or 2 by the European Union do not have a higher probability of benefiting from a collective protection measures. Exposures to products with a Binding Occupational Exposure Limit Value selectively benefited from a better level of protection. Exposures to agents entered on the International Agency for Research on Cancer (IARC) list of proven or probable carcinogens benefited more from effective collective protections than products suspected to be carcinogens but not yet classified by IARC.ConclusionsThese results suggest that the dissemination of evaluations of carcinogens by the IARC translate into improved protective measures even though the IARC classification has no mandatory impact on regulations.

Risk Of Falls

Objectives: In this study, we aimed to evaluate whether fibromyalgia patients had a higher fall risk compared to healthy individuals and to identify its relationship, if there was an increase, with clinical features. Patients and methods: Between March 2018 and September 2018, a total of 50 consecutive female patients with fibromyalgia (median age: 35 years; interquantile range [IQR], 27 to 40 years) and 50 healthy female volunteers (median age: 30 years; IQR, 23 to 40 years) were included in the study. Pain was evaluated with the Visual Analog Scale (VAS), life quality with the Nottingham Health Profile (NHP), balance functions with the Berg Balance Test (BBT), and the risk of falls with a posturography device. Disease activity of fibromyalgia patients was evaluated with the Fibromyalgia Impact Questionnaire (FIQ). Results: The mean fall risk index of the fibromyalgia patients was 45%. The fall risk index was significantly higher (p=0.010) and the BBT scores were significantly lower in the patient group (p<0.001). There was a significant difference in terms of fall risk between the control group and drug-free fibromyalgia patients; however, no significant difference was found between the balance scores of the two groups. In the fibromyalgia group, a weak positive relationship was determined between the fall risk index and the social isolation subscale of the NHP. Conclusion: Our study results showed an increased risk of loss of balance and falls in fibromyalgia patients, compared to healthy individuals. This fall risk increase was also detected in fibromyalgia patients who did not use drugs. These findings suggest a possible relationship between social isolation and an increased risk of falls.

SARS-CoV-2 infections in childcare and school settings potentially bear occupational risks to educational staff. We analyzed data derived from voluntary, PCR-based screening of childcare educators and teachers attending five testing sites in Berlin, Germany, between June and December 2020. Within seven months, 17,491 tests were performed (4,458 educators, 13,033 teachers). Participants were largely female (72.9%), and median age was 41 years. Overall, SARS-CoV-2 infection prevalence was 1.2% (95%CI, 1.1-1.4%). Prevalence in educational staff largely resembled community incidence until the start of the second pandemic wave in mid-September 2020, when an unsteady prevalence plateau was reached. Then, infection prevalence in teachers (1.2% [95%CI, 0.8-1.8%]) did not significantly differ from the population prevalence (0.9% [0.6-1.4%]) but it was increased in educators (2.6% [1.6-4.0%]; aOR, 1.6 [1.3-2.0]). Irrespective of occupation, those that reported contact to a confirmed SARS-CoV-2 case outside of work had increased risk of infection (aOR, 3.0 [95%CI, 1.5-5.5]). In a step-wise backwards selection, the best set of associated factors with SARS-CoV-2 infection involved age, occupation, and calendar week. These results are in line with findings that teachers do not bear an increased risk of SARS-CoV-2 infection, while childcare educators do. Infection control and prevention measures need to be strengthened in child care settings to further reduce respective occupational hazards. At the same time, the private environment appears to be the main source of SARS-CoV-2 infection for educational staff.
