The application of nanotechnology has gained importance in the finishing of textile products, imparting them functional properties, which are achieved without affecting the textile. A novel method was developed for the in situ growth of CuO nanoparticles (NPs) onto cotton textiles by the exhaust dyeing method. For functionalised textiles, a constant sodium hydroxide concentration (0.4 g l(-1)) and different percentages of on-weight-fabric (% owf) of copper acetate were used. The textiles were microbiologically evaluated, the laundering durability was assessed and their UV protection factor (UPF) was determined. In addition, their CIE L*a*b* colour coordinates and colour strength (K/S) were studied. The results determined that NPs on the textile were CuO and were distributed randomly on the cotton fibre surface. The functionalised textiles with CuO NPs had percentages of bacterial reducti...

Textiles functionalized with cupric oxide (CuO) nanoparticles have become a promising option to prevent the spread of diseases due to their antimicrobial properties, which strongly depend on the structure and morphology of the nanoparticles and the method used for the functionalization process. This article presents a review of work focused on textiles functionalized with CuO nanoparticles, which were classified into two groups, namely, in situ and ex situ. Moreover, the analyzed bacterial strains, the resistance of the antimicrobial properties of textiles to washing processes, and their cytotoxicity were identified. Finally, the possible antimicrobial mechanisms that could develop in Gram-positive and Gram-negative bacteria were described.

Este trabajo tuvo como objetivo principal determinar la relación existente entre calidad del servicio crediticio y satisfacción del socio de la Cooperativa de Ahorro y Crédito Norandino-2022. Para ello se utilizó la metodología descriptiva correlacional con diseño no experimental, asimismo; se aplicó una encuesta a 379 socios de la Cooperativa. Como resultados se encontró: que los productos crediticios y la satisfacción del socio tuvieron una correlación positiva moderada de 0.53, la calidad de atención al usuario y la satisfacción del socio tuvo una correlación negativa alta de -0,97, la calidad de servicio fue regular debido a la explicación y conocimiento de los productos crediticios por parte de los colaboradores, además se identificó que los clientes estuvieron satisfechos con algunos elementos tangibles como la ubicación, la seguridad y vigilancia del establecimien...

Objective: To determine the status of anemia and identify the sociodemographic factors associated with its development in children aged 6 to 59 months who attend first-level facilities, in the department of Tacna, during 2021. Material and methods: The study was carried out from a secondary database that collected data from children under 5 years of age who attended first-level health centers. A descriptive analysis and bivariate and multivariate analysis were performed, obtaining prevalence ratios and beta coefficients to determine the associated factors involved. Results: The prevalence of anemia in Tacna was 19.96 %. An inverse association was found between the variables age and health facility level (I-1, I-2, I-3 compared to level I-4), which were protective variables for the outcome. In the same way, the highest residence height in meters above sea level and the GDP per capita per ...

Introduction. Traffic accidents (TA) are a public health problem worldwide, with an estimated 1.3 million deaths per year from collisions and leaves traumatic sequels in the survivors. Of the total number of victims affected in an AT, injured pedestrians represent 22%. The objective of this study was to determine the factors associated with the requirement of physical rehabilitation of pedestrians injured by any TA in the Peruvian territory. Methods. An observational cross-sectional study was carried out with the data provided by the National Center for Epidemiology, Prevention, and Control of Diseases (CDC Peru) through epidemiological records. A regression analysis was performed, and prevalence ratios (PR) were reported, having the rehabilitation requirement as a dependent variable. Results. A total of 14,186 records of pedestrians injured by being hit by a motor vehicle on the road be...

Objective: To evaluate the trend and the years of life potentially lost in deaths due to traffic accidents in the department of Tacna. Material and methods: Observational study based on secondary data from the National System of Deaths of the Ministry of Health. A descriptive analysis of the general characteristics of the total number of deaths during the 2017-2021 period was carried out. Years of life lost were also calculated using the formula provided by the Global Burden of Disease. Results: A total of 245 deaths were obtained in the study period, the mean age was 42.98 years with a standard deviation of 19.58. 78 % of the victims were male. More than 80 % were reported in the province of Tacna. In 2020 there was a clear reduction in the number of deaths from traffic accidents. The years potentially lost in the study period were 12 012 years in total, with a large loss in the a...

Introduction: Maternal mortality (MM) is considered a public health problem and is regarded as an indicator for global health status. The objective of this study was to determine the epidemiological situation of MM by calculating the maternal mortality ratio (MMR) and years of potential life lost (YPLL) in Peru from 2002 to 2022. Methods: A study was conducted using data from the Maternal Mortality Situational Room and the National Institute of Statistics and Informatics. MMR were calculated annually at both the national and departmental levels from 2015 to 2022, while YPLL were calculated for each year between 2 002 and 2 022 based on data availability. Results: The highest MMR was observed in 2 021 at 106.56. The departments with the highest MMRs in 2022 were Amazonas with 173.31 and Loreto with 117.48. Tacna and Moquegua had annual periods with no maternal deaths. Between 2002 and 202...
