ABSTRACT

As with Amazonian primates, mixed associations between species in the Atlantic Forest are also influenced by ecological factors. However, Atlantic Forest primates may face additional challenges, such as isolation pressures and fragmentation of forest habitats, which may increase the frequency of these arrangements. The main of this work is to report a sympatry with possible interaction between individuals of two species of primates of the Pitheciidae and Callitrichidae families: Callicebus nigrifrons (Spix 1823) and Callithrix aurita (É. Geoffroy Saint-Hilaire 1812) in an urban park in the south of the state of Minas Gerais. Individuals were observed interacting during foraging and displacement. The association of individuals of the two species can be explained by the low quality of the forest fragment, as it can increases the chances of obtaining food resources and configures a dilution strategy against predator attacks.


Assim como ocorre com os primatas amazônicos, as associações mistas entre espécies na Mata Atlântica também são influenciadas por fatores ecológicos. No entanto, os primatas da Mata Atlântica podem enfrentar desafios adicionais, como pressões de isolamento e fragmentação de habitats florestais, que podem aumentar a frequência desses arranjos. O objetivo deste trabalho é apresentar um relato de simpatia com possível interação entre indivíduos de duas espécies de primatas das famílias Pitheciidae e Callitrichidae: Callicebus nigrifrons (Spix 1823) e Callithrix Resumo aurita (É. Geoffroy Saint-Hilaire 1812) em um parque urbano no sul do estado de Minas Gerais. Foram observados indivíduos interagindo durante o forrageio e deslocamento. A associação de indivíduos das duas espécies pode ser explicada devido à baixa qualidade do fragmento florestal, pois pode aumentar as chances de obter recursos alimentares e configura uma estratégia de diluição de contra-ataques de predadores.

ABSTRACT

【Objective】 To explore the optimization of blood testing strategies for voluntary blood donors in military blood centers. 【Methods】 From January 2017 to December 2020, the testing results of five serological indicators of voluntary blood donors from our center were collected via the blood transfusion management system . The positive NAT results of HBV, HCV and HIV, as well as the unqualified serological indicators, including the unqualified rate over the years, unqualified rate of military/civilian blood donor, reactive rate of dual-ELISA-reagent or one-ELISA-reagent etc., were retrospectively analyzed. 【Results】 The ratio of military blood donors to civilian blood donors in our center was 1: 4 during 2017~2020. The total unqualified rate of blood testing indicators of military blood donors was ALT>anti-HCV>HBsAg>HIV antigen/anti-HIV>anti-TP>NAT, and that of civilian blood donors was HBsAg > anti-TP > ALT > anti-HCV > HIV antigen/anti-HIV > NAT. The total unqualified rate of HBsAg, anti-HCV and anti-TP in our center decreased year by year, the HIV antigen/anti-HIV fluctuated, and the ALT increased year by year (P<0.01). The ALT deferral rate among military blood donors was the highest, accounting for 65.85%(594/902) of the donation deferral. The reactive rate of dual-ELISA-reagent to HBsAg, anti-HCV, HIV antigen/anti-HIV and anti-TP in civilian blood donors were 72.87%, 33.02%, 16.56% and 67.67%, respectively (P<0.05). Among the 123 668 ELISA negative samples during 2017~2020, 56 cases of HBV DNA(+ ) were detected by NAT, including 3 cases of military blood donors. 【Conclusion】 The current blood screening strategy of military blood centers can basically guarantee the safety of blood use in clinical. For military blood donors, ALT deferral, caused by ALT results that are higher than the ALT threshold, was the main reason for blood scrapping. Strengthening the promotion and implementation of NAT, as well as adjusting the critical value of ALT is of positive significance for reducing the risk of blood transfusion-transmitted diseases and the waste of blood sources, thereby improving the safety and security level of the clinical blood supply for the troops, promoting the treatment capabilities of officers and soldiers, and even improving the combat effectiveness of the troops.

ABSTRACT

Objective To establish a safety culture scale for conventional submarine troops and to analyze the key factors influencing the safety during peace time, so as to provide evidence for future study. Methods Twenty-five items from relative scales were sorted based on a literature review, and 21 of them were included in the final safety questionnaire after extensive analysis and review. A total of 180 submariners were surveyed with the questionnaire, and the effective response rate was 81. 67% (147) and their data were used for further analysis. Results Thirty-two (21. 77%) responders have experienced a safety incidence, and 12 (8. 16%) had been injured due to the incidences. Four dimensions of the safety culture for the target population were indentified by exploratory factor analysis, including commitment to safety by the decision-makers, satisfaction degree of safety effort, priority of safety effort, and communication on safety, which could explain 71. 532% of the variance. The Cronbach’s α was calculated for each scale (all over 0. 7). indicating satisfactory internal consistency for this measurement. Conclusion High incidence of safety events and injury rate of the participants from submarine troop demand more efforts on safety. Submariners are different from other seafarers in civil groups. They are trained to be obedient to orders and leadership, aware of the importance of missions; on the other hand they have stronger self-consciousness and they are not satisfied with simple emphasis on safety and repeated education. However, they are not active in reporting safety issues to the superiors, so the safety culture among them needs to be improved.

ABSTRACT

Objective To explore the correlation between TCM constitution and sleep status in escort troops. Methods Standardized TCM Constitution Questionnaire and Pittsburgh Sleep Quality Index (PSQI) were used to investigate escort troops. Factors of PSQI and constitution types were analyzed. Results The results of PSQI showed the number of escort troops who had bad sleeping (PSQI>7) was 64, which accounted for 46%of the escort troops, among which, 45 people (70.3%) were justified as biased constitution, while 19 were normal constitution (29.7%). The top three biased constitution in bad sleeping were:qi deficiency, phlegm-dampness and dampness-heat. PSQI factors such as sleep disorder, daytime dysfunction and total score had positive correlation with qi deficiency, yang deficiency, yin deficiency, dampness-heat and blood stasis, and negative correlation with normal constitution. Conclusion Sleep condition of escort troops has correlation with TCM constitution, which indicates that sleep status could be improved by regulating TCM constitution.
