Objective: Sexual violence affects women of all ages but, more commonly, children and adolescents. This study aimed to identify the extent to which services are being provided at the hospitals responsible for the emergency care of children and adolescents who have suffered sexual violence and to determine whether there is any difference in the provision of such services as a function of the victim’s age. Method: This cross-sectional study investigated differences in the care received by female children and adolescents who are victims of sexual violence in a capital city, comparing the treatment given to girls under 15 with that given to adolescents of 15 to 19 years of age. The data were extracted from the State Department of Health database between 01/01/2012 and 31/12/2016. Results: Children under 15 were much less likely to receive prophylaxis against HIV, sexually transmitted infections and hepatitis B, with the number of adolescent girls treated adequately corresponding to between twice and almost three times the number of children treated prophylactically. Only 10% of girls under 15 received emergency contraception. Conclusion: The lack of standard care established by the Ministry of Health highlights the need for urgent debates both locally and probably throughout the country, as the situation may be similar in other regions of the country.

本研究旨在考察当代中国三代同堂家庭中父母和祖辈的协同教养观念。研究选取10个家庭中的8位祖辈和8位父母,采用焦点小组访谈和个人访谈的方式搜集数据。研究结果表明:父亲与母亲平等地分担子女(10—13岁)的教养责任,祖辈在养育孙辈方面有从属的作用;祖辈的溺爱和滞后的养育方式是父母和祖辈间产生分歧的主要原因,但这种分歧可以通过沟通和支持来调和,并且父母和祖辈都认为沟通和支持是协同教养的关键。因此,在三代同堂家庭教育方面应加强父母(尤其是父亲)和祖辈对协同教养重要性的认识,明确祖辈“溺爱”界限,确保“帮忙不添乱”,以此减少祖辈和孩子父母之间的养育冲突,有效提升儿童的身心发展水平和幸福感。

Poly(lactic acid)(PLA)composite films reinforced with microcrystalline cellulose(MCC)extracted from pineapple leaf fibers(PALF)were prepared by a solution casting *** an attempt to improve the interaction between PLA and cellulose,two approaches were adopted;first,poly(ethylene glycol)(PEG)was used as a surfactant,and second,the cellulosic fibers were pre-treated using tert-butanol(TBA).Lignocellulosic and cellulosic substrates were characterized using Fourier transform infrared(FTIR),wide-angle X-ray scattering(WAXS),and thermogravimetrical analysis(TGA).MCC from PALF showed good thermal stability,left few residues after decomposing,and exhibited high crystallinity ***,thermal and thermomechanical properties of the PLA composites were also *** PLA endotherms were observed in composites with TBA-treated MCC due to crystal nucleation *** ultimate tensile strain values for all composites were lower than that of the pristine ***,4 wt.%MCC content provided balanced engineering properties in terms of static and dynamic tensile properties.

The incidence of Mycobacterium avium complex pulmonary disease (MACPD) has been globally increasing. The present study aims to provide a comprehensive analysis of clinical characteristics and treatment response among patients in the Amazon region of Brazil and conduct a retrospective cohort study at a prominent referral hospital in the State of Par, Brazil, from 2012 to 2020. The M. avium group represented 58.9% of cases, followed by M. intracellulare (35.7%), M. colombiense (3.6%), and M. chimaera (1.8%). The majority of patients (73.2%) were female and with an average age of 63 years. Primary clinical manifestations included persistent cough and sputum production. The Charlson comorbidity index (CCI) averaged 2.47, with 36.3% of patients having a CCI score equal to higher than 3. Notably, over 70% of patients had received treatment for pulmonary tuberculosis before initiating treatment for MAC infection. The fibrocavitary radiologic form was the most prevalent (55.4%), frequently exhibiting a bilateral distribution (53.6%). Antimicrobial susceptibility revealed a significant prevalence of MAC resistance to drugs in the therapeutic regimen. Despite this, most of the patients experienced clinical improvement (50%). In conclusion, this study highlights a higher prevalence of MAC infections among middle-aged women, with a history of pulmonary tuberculosis treatment and presenting the fibrocavitary radiological form was predominant.
