Chelonoidis Dcarbonaria and C. denticulata are two tortoises which are widely distributed Brazil. Although they occur sympatrically in different areas, C. carbonaria prefers open areas, while C. denticulata chooses forest areas. Significant morphological variations can be observed in these species due to the fact that they occupy a vast and environmentally diverse area. Data on shell shape of captive individuals reveal important differences between the two species, mainly in the plastron scutes, carapace width, and head length. Variation in shape is greater in C. carbonaria than in C. denticulata, which may be associated to a more elaborate and complex mating ritual. The shell shape in C. denticulata is more elongated than in C. carbonaria due to ecological habits. These aspects lead to a greater restriction in shape, limiting variation and dimorphism. In C. carbonaria, the shell opening is larger than in C. denticulata, which affords greater variation in shape. A more elongated shell facilitates movements of C. denticulata in densely forested areas. Yet, this characteristic reduces shell opening, lessening the possibilities of variation in form.Keywords: tortoise, carapace, plastron, shape.Variações morfológicas e dimorfismo sexual em Chelonoidis carbonaria (Spix, 1824) e Chelonoidis denticulata (Linnaeus, 1766) (Testudinidae) ResumoChelonoidis carbonaria e C. denticulata são duas espécies de jabutis com ampla distribuição no território brasileiro. Apesar de ocorrerem em simpatria em muitos locais, C. carbonaria apresenta predileção por áreas mais abertas e C. denticulata, por áreas de florestas mais densas. Por ocuparem extensa área com grandes variações ambientais, essas espécies apresentam grande variação nas características morfológicas. Dados da forma do casco de indivíduos cativos indicam importantes diferenças entre as espécies, principalmente nos escudos do plastrão, na largura da carapaça e no comprimento cefálico. Chelonoidis carbonaria apresenta maior variação da forma que C. denticulata, o que pode ser relacionado a um ritual de acasalamento mais elaborado e complexo. Chelonoidis denticulata possui corpo mais alongado que C. carbonaria, o que é atribuído aos seus hábitos; esse aspecto leva a uma maior restrição da forma, minimizando as possibilidades de variação do seu dimorfismo. A abertura no casco de C. carbonaria é maior que em C. denticulata, o que possibilita maior variação na forma. Um casco mais alongado facilita o deslocamento de C. denticulata em áreas de floresta densa, mas reduz a abertura desse casco, diminuindo as possibilidades de variação da forma.Palavras-chave: jabuti, carapaça, plastrão, forma.

Background: Knowing the rate of psychological distress and mental disorders, its severity, and factors associated with psychological distress is strategical during the COVID-19 pandemic.Method: We analyzed online cross-sectional data from 164,881 health professionals and from 5,635 participants from the general population in Brazil. The Global Severity Index (GSI) from the Brief Symptom Inventory, self-reported diagnosis of mental disorders, sociodemographic characteristics, and factors related to COVID-19 (physical health status, diagnosis and contact history, perceptions and concerns, and precautionary measures) were compared between samples. Multiple regression analysis was used to investigate factors related to GSI scores.Results: Psychological distress was high or very high in 13.4% of health professionals and in 31.4% of the general population. Health professionals reported a lower rate of mental disorders (36%) compared with the general population (44.7%). Age (younger) and gender (female) predicted higher psychological distress for health professionals and economic class (lower) and household size (more members) for the general population. People with higher GSI scores reported to have experienced more physical symptoms associated with COVID-19, feeling less productive at work, being afraid of transmitting the coronavirus to the family, fear of financial difficulties, and feeling that home relations were worse during the pandemic outbreak. Limitations: Internet access in Brazil depends on sociodemographic factors, biasing the recruitment towards people with greater education level and income. The male vs. female unbalance (1:4) is a factor to account for when interpreting data. Prevalence of psychiatric disorders was self-declared.Conclusions: Psychological distress at the first wave of COVID-19 was associated with sociodemographic features and an anxious perception of experiences and thoughts associated with the COVID-19 pandemic.

48%. There were several risk factor of it, such as night work or psychological demand. Conclusion This review of the literature showed the prevalence of work-related disorders among hospital doctors. The risk factors studied can guide prevention policies within hospitals. Introduction The trade of laboratory technician (TL) exposes to many risks to health, because of biological or chemical or physical exposures. But the TL occupation is constantly evolving, the techniques are constantly changing. The purpose of this article is to take stock of the occupational TL pathologies which were recently described in the literature. Material and method This is a literature review, based on Medline and Scopus medical databases, on publications between 01/01/2006 and 31/12/2016. The research was conducted in French and English. Only articles about TL in Hospital or Teaching Hospital were selected. Results Twenty-eight articles were studied. The main infectious pathology described was brucellosis; A case of meningitis was studied. The cutaneous allergies reported concerned sensitisation to certain solvents. There was no allergy to latex. Musculoskeletal disorders (MSD) were studied in 4 articles. The main MSDs were low back pain and neck pain. Several articles have been alerted on the occurrence of burnout syndrome (BO). However, no prevalence studies were conducted over the period studied. Conclusion LT can present many occupational pathologies. Few articles studied the prevalence of MSD and BO. Introduction The occupational divers are subject to numerous risks. For instance, divers can get infections. We review the infectious diseases in professional divers. Materials and methods This is a literature review until 30/05/ 2017. The research was conducted on Medline and Scopus databases, in French and English languages. Results Fifteen papers report cases of infections in professional divers. These are mainly skin infections, but also ENT and ophthalmological infections. Discussion-conclusion According to data collected, infections among professional divers are quite rare. These diseases are not specific to the workplace, and are comparable with data on recreational diving. Prevention is mainly based on hygiene and equipment maintenance. Introduction The junior doctors are subject to several professional constraints. This study aims to assess the prevalence of anxiety, depressive disorder and burnout (BO) and their risk factors. Material and method This is a review of the literature between 01/01/2004 and 31/10/2014. A prevalence were calculated for a virtual population. Results The prevalence of anxiety disorders was between 15.8% and 87% depending on the study; that of mood disorder was between 16.3% and 48%. The prevalences of virtual populations were 32.5% and 21.7% respectively. BO prevalence was between 10% and 80.2% while prevalence for virtual population was 33.2%. Several studies have shown that working hours, study or work relations were risk factors. Conclusion The data in the literature ranged from one study to a...

Results There was a significant reduction in admission rates after institution of the new policy. The proportion of hospital admissions to PED observation unit cases was significantly reduced as a whole from 64.9% ± 5.1% to 33.2 ± 0.6% and also for the common paediatric problems studied. Conclusion A multidisciplinary paediatric emergency department policy, using as much available evidence as possible, was successful in significantly reducing paediatric hospital admissions.
