Abstract
BACKGROUND Nursing is a stressful occupation with high rates of sickness absence. To date, there are no meta-analyses that statistically determined the correlates of sickness absence in this population. AIMS This meta-analysis examined organizational and psychosocial predictors of sickness absence among nursing staff. METHODS As a registered systematic review (PROSPERO: CRD42017071040), which followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, five databases (CINAHL, PROQuest Allied, PROQuest database theses, PsycINFO, PubMed) were reviewed to examine predictors of sickness absence in nurses and nursing assistants between 1990 and 2019. The Population/Intervention/Comparison/Outcome tool was used to support our searches. Effect sizes were analysed using random-effects model. RESULTS Following critical appraisals using (i) National Institutes of Health's Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies and (ii) Strengthening the Reporting of Observational Studies in Epidemiology, 21 studies were included. Nursing assistants had greater odds of sickness absence than nurses. Working night shifts, in paediatrics or psychiatric units, experiencing poor mental health, and fatigue, also increased the odds of sickness absence. There was no evidence that job satisfaction or job strain influenced sickness absence; however, job demand increased the likelihood. Finally, work support reduced the odds of lost-time. CONCLUSIONS We synthesized three decades of research where several factors influenced sickness absence. Due to limited recent research, the results should be interpreted with caution as some practices may have changed overtime or between countries. Nevertheless, these findings could help in applying preventative strategies to mitigate lost-time in a vulnerable working population.

Abstract
Background The mining industry is associated with high levels of accidents, injuries and illnesses. Lost-time injuries are useful measures of health and safety in mines, and the effectiveness of its safety programmes. Aims To identify the type of lost-time injuries in the US mining workforce and to examine predictors of these occupational injuries. Methods Primary papers on lost-time injuries in the US mining sector were identified through a literature search in eight health, geology and mining databases, using a systematic review protocol tailored to each database. The Critical Appraisal Skills Programme (CASP), Framework of Quality Assurance for Administrative Data Source and the Cochrane Collaboration 'Risk of bias' assessment tools were used to assess study quality. Results A total of 1736 articles were retrieved before duplicates were removed. Fifteen articles were ultimately included with a CASP mean score of 6.33 (SD 0.62) out of 10. Predictors of lost-time injuries included slips and falls, electric injuries, use of mining equipment, working in underground mining, worker's age and occupational experience. Conclusions This is the first systematic review of lost-time injuries in the US mining sector. The results support the need for further research on factors that contribute to workplace lost-time injuries as there is limited literature on the topic. Safety analytics should also be applied to uncover new trends and predict the likelihood of future incidents before they occur. New insights will allow employers to prevent injuries and foster a safer workplace environment by implementing successful occupational health and safety programmes.

Abstract
Abstract
Large-scale sequencing initiatives have revealed a wealth of common and novel variants as well as copy-number aberrations, across different malignancies. This growing list of variants/aberrations can sometimes be matched to specific therapeutics. Such “actionable mutations/changes” hold promise for personalized treatment in the future, with treatments tailored to molecular abnormalities. Presently, women with hormone positive early breast cancer continue to experience improved survival on adjuvant anti-hormone therapy, but a significant number of women continue to progress. Therefore, there is a need to identify those women for whom current therapies are insufficient and to identify alternative therapeutic interventions. We explored the used of genetic profiling using a comprehensive solid tumor next generation sequencing (NGS) assay (the Oncomine Comprehensive Assay, OCA) to characterize early invasive breast cancer. The OCA is based on the Ion Torrent™ NGS platform and Ion AmpliSeq™ library preparation technology, coupled to the Oncomine™ Knowledgebase, for target selection, variant calling, and data annotations. The OCA includes 87 genes for hotspot mutation detection, 48 genes for full length sequencing and 43 genes for focal copy number assessment. The OCA provides a standardized informatics workflow and quality control (QC) parameters to process samples in a translational clinical research setting. To explore the application of the OCA to early invasive breast cancers, we performed a retrospective pilot study in a subset of cases from the TEAM trial. From the TEAM pathology samples, 420 were chosen in a case-control fashion, 413 samples were analyzed, 388 samples passed standard QC metrics, and 254 samples (65%) were found to contain 368 variants with Oncomine Knowledgebase annotations. Briefly, variants of PIK3CA were most frequent at 42.7% (157/368), followed by TP53 at 27.2% (100/368), PTEN at 5.7% (21/368), BRCA2 at 3.8% (14/368), SF3B1 (12/368), AKT1 (11/368) and PTCH1 (11/368) at 3.3%, 3.0%, 3.0%; respectively. Other variants were detected in ATM, ERBB2, RB1, FGFR2, NF1, CDKN2A, PIK3R1 and others. Amongst the 43 genes assessed for copy-number, 23 showed copy-number changes across 132 samples totalling 167 CNVs. 256 samples showed no copy-number alterations in any of the genes on the panel. ERBB2 was most frequently altered at 28.1% (47/167), followed by FGFR1 at 23.4% (39/167), CCND1 at 15.0% (25/167) and MDM2 at 10.2% (17/167). Copy-number losses were identified in TP53, RB1, PTEN, BRCA2 at 0.6% each; as well as CDKN2A at 1.8% (3/167). Analytical validation of a subset of gene variants and copy-number changes will be presented in addition to the evidence of potential future application of the Oncomine Comprehensive Assay to precision oncology goals.

Abstract
INTRODUCTION The seasonal profession of wildland fire fighting in Canada requires individuals to work in harsh environmental conditions that are physically demanding. The purpose of this study was to use novel technologies to evaluate the physiological demands and nutritional practices of Canadian FireRangers during fire deployments. METHODS Participants (n = 21) from a northern Ontario Fire Base volunteered for this study and data collection occurred during the 2014 fire season and included Initial Attack (IA), Project Fire (P), and Fire Base (B) deployments. Deployment-specific energy demands and physiological responses were measured using heart-rate variability (HRV) monitoring devices (Zephyr BioHarness3 units). Food consumption behaviour and nutrient quantity and quality were captured using audio-video food logs on iPod Touches and analyzed by NutriBase Pro 11 software. RESULTS Insufficient kilocalories were consumed relative to expenditure for all deployment types. Average daily kilocalories consumed: IA: 3758 (80% consumption rate); P: 2945±888.8; B: 2433±570.8. Average daily kilocalorie expenditure: IA: 4538±106.3; P: 4012±1164.8; B: 2842±649.9. The Average Macronutrient Distribution Range (AMDR) for protein was acceptable: 22-25% (across deployment types). Whereas the AMDR for fat and carbohydrates were high: 40-50%; and low: 27-37% respectively, across deployment types. CONCLUSIONS This study is the first to use the described methodology to simultaneously evaluate energy expenditures and nutritional practices in an occupational setting. The results support the use of HRV monitoring and video-food capture, in occupational field settings, to assess job demands. FireRangers expended the most energy during IA, and the least during B deployments. These results indicate the need to develop strategies centered on maintaining physical fitness and improving food practices.

Abstract
INTRODUCTION Literature from the past two decades has presented an insufficient amount of research conducted on the nursing practice environments of registered practical nurses (RPNs). The objective of this article was to investigate the barriers and facilitators to sustaining the nursing workforce in north-eastern Ontario (NEO), Canada. In particular, retention factors for RPNs were examined. METHODS This cross-sectional research used a self-administered questionnaire. Home addresses of RPNs working in NEO were obtained from the College of Nurses of Ontario (CNO). Following a modified Dillman approach with two mail-outs, survey packages were sent to a random sample of RPNs (N=1337) within the NEO region. Logistic regression analyses were used to determine intent to stay (ITS) in relation to the following factor categories: demographic, and job and career satisfaction. RESULTS Completed questionnaires were received from 506 respondents (37.8% response rate). The likeliness of ITS in the RPNs' current position for the next 5 years among nurses aged 46-56 years were greater than RPNs in the other age groups. Furthermore, the lifestyle of NEO, internal staff development, working in nursing for 14-22.5 years, and working less than 1 hour of overtime per week were factors associated with the intention to stay. CONCLUSIONS Having an understanding of the work environment may contribute to recruitment and retention strategy development. The results of this study may assist with addressing the nursing shortage in rural and northern areas through improved retention strategies of RPNs.

Abstract
BACKGROUND Forest firefighters are faced with multiple physical and psychological challenges as a result of their duties. Little is known about the determinants of injury among these workers. The Ontario Ministry of Natural Resources (OMNR) Aviation, Forest Fire and Emergency Services (AFFES) records detailed information on two mutually exclusive types of workplace injury: First aid (self-reported) and Workplace Safety Insurance Board (WSIB, i.e. received medical attention). AIMS To identify the contributions of physical and psychological factors on the likelihood of injury among forest firefighters. METHODS Participants were male and female forest firefighters aged between 18 and 65. Data were collected using two self-administered instruments: The NEO Personality Inventory and the Job Stress Survey. Secondary data were collected from the OMNR AFFES and data were analysed by way of multivariate statistical procedures. RESULTS There were 252 participants. Those who were older, had a history of injury, had high scores for the personality construct of Neuroticism or low scores for the Openness construct were significantly more likely to incur a first aid injury, while those with high experience levels were significantly less likely to incur injury (P < 0.05). High job stress was the only significant predictor of WSIB injury (P < 0.05). CONCLUSIONS First aid and WSIB injuries in the OMNR AFFES were quite distinct phenomena and different factors need consideration in their prediction. It is recommended that managers and decision-makers in this field consider factors such as job stress, personality and the prior occurrence of injuries in their assessment of risk.

Abstract
CONTEXT Water birth is under debate among professionals. For the proponents of this approach, immersion in water during labour and birth may increase maternal relaxation, reduce analgesia requirements and promote a model of obstetric care more focused on the needs of mothers, particularly the empowerment of women to realize their full potential. In contrast, major critics cite a risk of inhalation of water for the newborn and a risk of infection for the mother and the newborn. OBJECTIVE This review tracks the state of scientific knowledge about water birth in order to determine if it can be generalized in hospitals. METHOD A systematic review of the literature was conducted in PubMed, Embase and Cochrane Database. The period covered is from January 1989 to May 2013. The level of evidence of the studies was assessed with the analysis guide of the Haute Autorité de santé. RESULTS The level of evidence of the studies identified goes from moderate to low, particularly as regard to studies analysing the expulsion phase. CONCLUSION It is possible to recommend immersion in water during the labour phase. No recommendation can be made as regard to the foetal expulsion phase.

Abstract
Microsporidia are worldwide ubiquitous intracellular protozoan parasites infecting most major groups of the animal kingdom. In humans, microsporidiosis has recently emerged as a significant cause of morbidity in immunocompromised patients, and particularly in patients with acquired immunodeficiency syndrome (AIDS). Parasites of the genus Encephalitozoon cause keratoconjunctivitis and disseminated infections. In 15 to 30% of patients with advanced stage AIDS, Enterocytozoon bieneusi is the causative agent of major chronic diarrhoea. Clinical manifestations include numerous (2 to 8) and abundant, irregular liquid or semi-liquid stools without evidence of intestinal haemorrhage. Impaired absorption is aggravated by food intake causing the patients to restrain from eating and subsequent weight loss is progressive and irreversible. The diarrhoea becomes permanent and leads to dehydration ad malnutrition. Spontaneous remissions have been observed but are always of short duration. Microsporidiosis has also been found in ocular localizations in patients with AIDS; these keratopathies may be due to Encephalitozoon cuniculi, the only known species in mammals but E. hellem, a morphologically identical but antigenically different species has been identified. Other visceral localizations have been observed. Diagnosis of microsporidiosis relies on the demonstration of spores and/or intracellular parasites in stools, urine or tissue biopsies. The responsible agent can generally be identified by light microscopy, but differentiation between species still requires electron microscopy. New light and fluorescent microscopic techniques have been proposed for easier recognition of spores in various pathological samples. Immunodiagnostic techniques are limited due to the lack of correlation between antibodies detection and clinical manifestations. Although the parasite can be identified and although its cycle has been carefully studied, no prophylactic action can be taken because the mode of transmission remains largely unknown. Many treatment protocols have been tried but none have been found to be effective. Very little pharmacological data has been accumulated. Microsporidiosis is, and will remain, a major opportunistic infectious disease causing uncontrollable debilitating malnutrition in AIDS patients unless an effective treatment can be found, a major challenge for medical science.

Abstract
Schistosomiasis is endemic in three continents: Africa, where Schistosoma haematobium, S. mansoni and S. intercalatum are present; tropical America and some of the the Caribbean islands, where the only parasite of this type is S. mansoni; Mediterranean Asia (S. haematobium, S. mansoni) and the Far-East (S. japonicum, S. mekongi). Schistosomal infestation is distributed in foci of warying size and significantly differs in prevalence, intensity and therefore morbidity from one region to another. Despite the successes obtained in the neutralization of certain foci, the great plasticity of the hosts-parasites-molluscs relations and the huge displacements of human populations in the poorer countries explain why the epidemiology of schistosomiasis is constantly changing and the disease is far from disappearing.

Abstract
Two hundred and twenty adult males living in endemic onchocerciasis areas in Ivory Coast, with a mean of 59 to 64 mf/mg of skin microfilariae, having or not ocular lesions, were divided into 4 homogeneous groups and treated by placebo or by a single oral dose of 100, 150 or 200 mcg/kg of ivermectin. Parasitological, clinical, ophthalmological, biological data were gathered before treatment (J less than 1) and at day 4 and 3, 6, 12 months post treatment. The doses of 150 to 200 mcg/kg gave the best results with a reduction of microfilariae of 75 to 79% at day 4 and of 97 to 99% at 3 months. A slight increase appears at six months reaching to 10% of the initial level, at 12 months. These posologies reduce also the number of ocular microfilariae 12 months after treatment. The percentage of patients presenting microfilariae in the cornea varies from 4 to 14% according to the given dose whereas it was initially between 26 and 33%, and in the anterior chamber from 22 to 16% instead of 62 to 67%. In patients who were still positive after treatment the detected number of ocular microfilariae was very small. Side effects starting 12 to 24 hours after treatment are similar to those appearing during the normal evolution of onchocerciasis. They were observed in 36% of subjects receiving a placebo and 56 to 65% of treated subjects. Statistically they are neither correlated with the intensity of parasitism nor to the given posology and disappear spontaneously few days later or after administration of aspirin and/or antihistaminic. Ivermectin given at a single oral dosage of 150 to 200 mcg/kg is a powerful microfilaricidal drug with a rapid and prolonged action and without major side effects.

Abstract
One hundred and twenty patients out of 220 in a previous study were retreated after 6 months or one year with doses of 100, 150 or 200 mcg/kg of ivermectin. The tolerance was excellent due probably to the small number of skin microfilariae obtained with the first treatment. The annual treatment with 150 to 200 mcg/kg, better than with 100 mcg/kg, keeps for the year following the second treatment the microfilariae number between 6 and 11% of the initial level. The half-yearly administration keeps it between 1 and 7% and especially 94 to 100% of these retreated patients have a level of microfilariae less than 5 mf/mg. The results obtained with the half-yearly treatment show a considerable reduction of the number of microfilariae in the anterior chamber of the eye and the percentage of positive patients. Ivermectin is a very efficient microfilaricidal drug for the treatment of onchocerciasis and the prevention of ocular complications. Its rational use in mass campaigns should reduce, if not interrupt, the transmission of this parasitic disease.

Abstract
One hundred and three male and female children of 6 to 14 years old with onchocerciasis, having or not ocular involvement and a mean skin microfilariae level of 36.1 mf/mg, received, in October 1986, a single oral dose of 150 mcg/kg ivermectin and controlled at day 4, 3 months, 6 months and 12 months post treatment. After the last control they were retreated with the same dose. The skin microfilariae count fell down to 94% of the initial level at day 4 and to 99% at 3 months. At 6 months the microfilariae count was 2% of the initial level and 5% at 12 months. The percentage of patients having microfilariae in the anterior chamber of the eye which was 33% before treatment fell down to 6% at 12 months. The percentage of patients having microfilariae in the cornea was 39% before treatment and 18% at 12 months. In the cornea and anterior chamber there was a very reduced number of microfilariae still present. 65% of the children had lesions of keratitis before treatment and 34% two months later. Adverse effects (fever, headache, pruritus, oedemas, myalgias, arthralgias) occurred in 64% of children after the first treatment and 50% after the second. They were of weak or moderate intensity and receded rapidly after administration of aspirin and/or anti-histaminic. The administration of ivermectin is an efficient and well tolerated drug in children above 5 years old.

Abstract
Forty carriers of 20 or more W. bancrofti var. pacifica per ml were blind administered ivermectin at 50, 100, 150 or 200 mcg/kg doses. The rate of successful treatment was 100% with the 4 dosages. The percentage cure rate and the decrease percentage in the microfilarial count were significantly higher in persons treated with 100, 150 and 200 mcg/kg than in persons treated with 50 mcg/kg. Frequency and intensity of side-reactions were similar to those observed during treatment with DEC; they were more frequent and severe in persons with greatest microfilaremia but did not depend on the dosage. Ivermectin in 100 mcg/kg single-dose, administered once a year, is the best candidate to replace DEC in mass treatments.

Abstract
In 1981, 32 adult Senegalese males infected with Onchocerca volvulus but without ocular involvement were treated by groups of 8 with single oral dosages of 5, 10, 30 or 50 micrograms/kg of ivermectin . As soon as the second day after treatment, we observed a marked decrease of the dermal microfilaremic charge after a posology of 30 micrograms/kg. However the decrease is most important in the group subjected to 50 micrograms/kg and 75% of them had no more microfilariae in the dermis 28 days following treatment.

Abstract
Twenty immigrants from Mali and West Senegal were treated in Paris. Onchocerciasis was diagnosed by six skin snips using a Holth punch. Ivermectine was given in a single oral dose: ten patients were given 50 mcg/kg, three were given 75 mcg/kg and seven received 100 mcg/kg. No patients had ocular symptoms. The results were as follows: Pruritus disappeared rapidly in 9 out of 11 patients who itched before treatment. The microfilarial load decreased rapidly, especially in cases treated with 75 mcg/kg and 100 mcg/kg as all patients tested on day 60 were negative. Clinical signs of the Mazzotti reaction and ocular reactions were not observed following the treatment. Pruritus was briefly aggravated in only two patients. No cardiovascular, hematological, hepatic or renal toxicity was noted.

1,448 sera taken from individuals of various places of South-Eastern Gabon have been studied by means of indirect immunofluorescence and Fulton direct agglutination associated with 2-mercapto-ethanol test, 52.6% contained antitoxiplasmic antibodies. This study showed that toxoplasmic infection occurs early in both sexes, that it is more frequent in men (57.9%) than in women (45.4%), that the Ogooué-Lolo province is more contaminated (62.6%) than the High Ogooué province (49.6%). It seems that prevalence differences are less dependent upon the telluric elimate than upon other factors, which remain to find.

Abstract
A survey of 1,548 stools samples carried out in Gabon showed in the adult population a parasitism ratio of about 100%. Among the protozoa, D. fragilis was found in 0.3% of the cases. In contradiction with the usual observations in tropical Africa, A. lumbricoides and T. trichiura infestation is very high in the villages. The demonstration of S. intercalatum in almost every place of the survey and an important focus at Okondja proves the extension of this bilharziosis.

Abstract
The severity of ascaridiasis in a region depends first of all on the degree of pollution by ascaris ova of the environemtn and consquently on the per diem output of ascaris ova in the stools. Therefore, the importance of ascaridiasis as an endemic disease, depends of course upon the number of positive cases, their prevalence, but still more, it depends upon the intensity of the infection of the diseased population (global parasitic discharge). Practically, this concept of global parasitic discharge is expressed by the number of ascaris ova expelled per gram and per day by a sample of the considered population. The mean parasitic discharge is the quotient of the global parasitic discharge through the number of positive cases of the sample. An epidemiological survey and a mass chemotherapy test at La Réunion has showed us that the conept of global parasitic discharge is a more representative reliable and sensitive measuring method than prevalence, to evaluate the gravity of endemic ascaridiasis and its variations.
