O polietileno tereftalato (PET) se tornou um dos materiais plásticos mais utilizados mundialmente devido à sua versatilidade e baixo custo de produção. Todavia, problemas ambientais decorrem da destinação inadequada deste material e dos grandes volumes ocupados em aterros sanitários, considerando o longo tempo de decomposição do PET. Nesse cenário, a indústria da construção civil possui grande potencial para incorporação de resíduos advindos de outros sistemas produtivos. Dentre as alternativas para o emprego do PET, cita-se a incorporação em traços para a produção de concreto e argamassas em geral. Desta forma, este estudo objetivou avaliar as propriedades mecânicas de argamassas produzidas com substituição parcial do agregado miúdo por PET triturado. Para tanto, dois traços foram produzidos com diferentes proporções de aglomerante e agregado miúdo utilizando cimento Portland CP ll Z-32, cal, areia e PET triturado nas porcentagens de 5%, 10%, 15%, 20% e 25% em substituição à areia. Ensaios de resistência à compressão simples e resistência à tração por compressão diametral foram realizados. Observou-se um aumento de ambas as resistências determinadas com o aumento da porcentagem de PET a partir dos 14 dias. Os resultados obtidos indicam que a utilização de PET em substituição parcial ao agregado miúdo convencional pode promover melhorias nas propriedades mecânicas de argamassas.

Published: March 2022

Авторы разработали и реализовали методику прогнозирования численности российских прародителей. Она состоит из двух частей: методика прогнозирования численности потенциальных прародителей, в целом, и активных прародителей (участвующих в уходе, воспитании внуков), в частности. Две части методики предполагают разные источники информации, имеют свои особенности, подробно описанные в статье. Применение методик позволило построить прогноз увеличения численности и потенциальных, и активных прародителей в России. Методическая ценность проведенного исследования состоит в развитии демографического прогнозирования, а практическая - в потенциальной востребованности этих результатов для усиления информационной поддержки процесса реализации национального проекта «Демография».
Grandparenthood is considered in the paper as a mechanism for the effective implementation of the resource potential of older people. The authors developed and implemented a methodology for forecasting the number of Russian grandparents. It consists of two parts: methodology for predicting the number of potential grandparents in general and active grandparents (involved in the care and upbringing of grandchildren) in particular. The two parts of the methodology involve different sources of information and have their own characteristics, which are described in detail in the paper. The use of the methods allowed us to make a forecast of the growth of the number of both potential and active grandparents in Russia. The methodological value of the study is the development of demographic forecasting, and the practical value is the potential relevance of these results to strengthen information support for the implementation of the national project «Demography».

Цель исследования - изучение связи показателей когнитивных функций (КФ) с модифицируемыми факторами риска хронических неинфекционных заболеваний (ХНИЗ) в одномоментном подходе в городской российской популяционной выборке 55-84 лет. Изучена случайная выборка - 3 153 человека (мужчины и женщины 55-84 лет) из общей популяционной когорты жителей Новосибирска, обследованной в рамках международного проекта HAPIEE. Протокол исследования включал стандартизованное нейропсихологическое тестирование (количественная оценка функции памяти, семантической речевой активности и концентрации внимания), стандартизованную оценку факторов риска, истории и лечения сердечно-сосудистых заболеваний и ХНИЗ. По результатам кросс-секционного анализа выявлена прямая связь показателей КФ с уровнем образования и обратная связь с метаболическими факторами риска и курением у лиц обоего пола. Уровень общего холестерина и умеренное потребление алкоголя были положительно связаны с КФ у женщин. Эти связи не зависели от возраста и других факторов.
We aimed to investigate the relationship between the indicators of cognitive functions (CF) and modifiable risk factors for chronic non-communicable diseases (NCD) in a cross-sectional analysis in the urban Russian population sample aged 55-84 years. The study investigated a random sample of 3 153 people (men and women 55-84 years old) from a general population cohort of Novosibirsk residents; a sample was examined within the international project HAPIEE. The study protocol included standardized neuropsychological tests (quantitative assessment of memory, semantic verbal fluency, attention and processing speed) and standardized assessment of risk factors, history and treatment of cardiovascular disease and NCD. In cross-sectional analysis we observed a positive relationship of CF indices with level of education and an inverse relationship with metabolic risk factors and smoking in both sexes. The level of total cholesterol and moderate alcohol consumption had positive relationship with CF indices in women. These associations were independent from age and other factors.

Background: Given the increased attention to functional improvement in spine surgery as it relates to motion preservation, activities of daily living, and cost, it is critical to fully understand the healthcare economic impact of new devices being tested in large FDA randomized controlled trials (RCT). The purpose of this analysis was to comprehensively evaluate the cost-effectiveness of the novel Total Posterior Spine (TOPS™) System investigational device compared with the trial control group, standard transforaminal lumbar interbody fusion (TLIF). Objective: To evaluate the cost-effectiveness of TOPS™ compared with TLIF. Methods: The study patient population was extracted from a multicenter RCT with current enrollment at n=121 with complete 1-year follow-up. The primary outcome was cost-effectiveness, expressed as the incremental cost-effectiveness ratio. Secondary outcomes were health-related utility, presented as quality-adjusted life-years (QALYs), and cost, calculated in US dollars. Analysis was conducted following Second Panel on Cost-Effectiveness Health and Medicine recommendations. The base case analysis utilized SF-36 survey data from the RCT. Both cost and QALY outcomes were discounted at a yearly rate of 3% to reflect their present value. A cohort Markov model was constructed to analyze perioperative and postoperative costs and QALYs for both TOPS™ and control groups. Scenario, probabilistic, and threshold sensitivity analyses were conducted to determine model discrimination and calibration. Results: The primary time horizon used to estimate cost and health utility was 2 years after index surgery. From a health system perspective, assuming a 50/50 split between Medicare and private payers, the TOPS™ cohort is cost-effective 2 years postoperatively ($6158/QALY) compared with control. At 6 years and beyond, TOPS™ becomes dominant, irrespective of payer mix and surgical setting. At willingness-to-pay thresholds of $100 000/QALY, 63% of all 5000 input parameter simulations favor TOPS, even with a $4000 upcharge vs TLIF. Discussion: The novel TOPS™ device is cost-effective compared with TLIF and becomes the dominant economic strategy over time. Conclusions: In the emerging, rapidly expanding field of value-based medicine, there will be an increased demand for these analyses, ensuring surgeons are empowered to make the best, most sustainable solutions for their patients and society.
