Publicación Acceso abierto Estimating mortality and disability in Peru before the COVID-19 pandemic: a systematic analysis from the Global Burden of the Disease Study 2019(Frontiers Media SA, 2023-06-22) Rios-Blancas, Maria Jesus ; Pando-Robles, Victoria ; Razo, Christian ; Mendoza, Walter ; Carcamo, Cesar P. ; Pacheco-Barrios, Kevin ; Miranda, J. Jaime ; Lansingh, Van Charles ; Gezahegn Demie, Takele ; Saha, Manika ; Okonji, Osaretin Christabel ; Yigit, Arzu ; Cahuana-Hurtado, Lucero ; Chacón-Uscamaita, Pamela R.; Bernabe, Eduardo; Culquichicon, Carlos ; Chirinos-Caceres, Jesus Lorenzo ; Cárdenas, Rosario ; Alcalde-Rabana, Jacqueline Elizabeth ; Barrera, Francisco J.“Background: Estimating and analyzing trends and patterns of health loss are essential to promote efficient resource allocation and improve Peru’s healthcare system performance. Methods: Using estimates from the Global Burden of Disease (GBD), Injuries, and Risk Factors Study (2019), we assessed mortality and disability in Peru from 1990 to 2019. We report demographic and epidemiologic trends in terms of population, life expectancy at birth (LE), mortality, incidence, prevalence, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) caused by the major diseases and risk factors in Peru. Finally, we compared Peru with 16 countries in the Latin American (LA) region. Results: The Peruvian population reached 33.9 million inhabitants (49.9% women) in 2019. From 1990 to 2019, LE at birth increased from 69.2 (95% uncertainty interval 67.8–70.3) to 80.3 (77.2–83.2) years. This increase was driven by the decline in under-5 mortality (−80.7%) and mortality from infectious diseases in older age groups (+60 years old). The number of DALYs in 1990 was 9.2 million (8.5–10.1) and reached 7.5 million (6.1–9.0) in 2019. The proportion of DALYs due to non-communicable diseases (NCDs) increased from 38.2% in 1990 to 67.9% in 2019. The all-ages and age-standardized DALYs rates and YLLs rates decreased, but YLDs rates remained constant. In 2019, the leading causes of DALYs were neonatal disorders, lower respiratory infections (LRIs), ischemic heart disease, road injuries, and low back pain. The leading risk factors associated with DALYs in 2019 were undernutrition, high body mass index, high fasting plasma glucose, and air pollution. Before the COVID-19 pandemic, Peru experienced one of the highest LRIs-DALYs rates in the LA region. Conclusion: In the last three decades, Peru experienced significant improvements in LE and child survival and an increase in the burden of NCDs and associated disability. The Peruvian healthcare system must be redesigned to respond to this epidemiological transition. The new design should aim to reduce premature deaths and maintain healthy longevity, focusing on effective coverage and treatment of NCDs and reducing and managing the related disability.“Publicación Acceso abierto Association between alcohol consumption and overweight among university students in Latin America(SOC CHILENA NUTRICION, BROMATOLOGIA & TOXICOLOGIA, 2023-05-21) Parra-Soto, Solange ; Araya, Carolina ; Morales, Gladys ; Araneda Flores, Jacqueline ; Landaeta-Díaz, Leslie ; Gabriela Murillo, Ana; Gomez, Georgina ; Ríos-Castillo, Israel ; Carpio-Arias, Valeria ; Cavagnari, Brian M ; Nava-Gonzalez, Edna J. ; Bejarano-Roncancio, Jhon Jairo ; Núñez-Martínez, Beatriz Elizabeth ; Cordón-Arrivillag, Karla ; Meza-Miranda, Eliana Romina ; Mauricio-Alza, Saby ; Durán Agüero, SamuelIntroducción: El sobrepeso y la obesidad son problemas de salud pública de nivel mundial. Si bien existe información respecto al consumo de alcohol en estudiantes universitarios durante la pandemia, pocos autores han señalado la asociación entre este hábito y el exceso de peso en esta población. El objetivo fue determinar la asociación entre el consumo de alcohol y el exceso de peso en estudiantes universitarios de 10 países de Latinoamérica durante la pandemia por COVID-19. Metodología: Se realizó un estudio transversal y multicéntrico con 4.539 estudiantes universitarios matriculados en diez países de América Latina. Para la valoración del consumo de alcohol se utilizó la pregunta ¿Consumes bebidas alcohólicas? (1 porción 1 vaso de 200 ml). El índice de masa corporal (IMC) se determinó a partir del peso y la altura auto informado. Para determinar si el exceso de peso (IMC ≥25 kg/m2 ) estaba asociado con el consumo de alcohol, se utilizó un análisis de regresión logística, ajustado por edad, sexo, año de estudio, nivel socioeconómico, actividad física y tabaquismo. Resultados: Entre los estudiantes con estado nutricional normal, un 59,6% no consumía alcohol, mientras entre los que presentaban un exceso de peso era un 55,1%. Los estudiantes que consumían 2 o más porciones de alcohol al día tenían 2,18 veces más riesgo de tener exceso de peso (OR: 2.18 [95% IC: 1,26 a 3,77]), comparado con aquellos que no consumían alcohol. Conclusión: Se observó que aquellos estudiantes que consumieron más alcohol tuvieron más probabilidades de tener exceso de peso.

Further characterization of LCC patients experiencing activity limitations and their associated healthcare use is needed. This study aimed to describe LCC patients’ characteristics, its impact on activities, and associated healthcare use in Latin America (LATAM). Participants: Individuals who (cared for someone or) had COVID-19 and could read, write, and comprehend Spanish and lived in a LATAM country were invited to complete a virtual survey. Sociodemographic characteristics, COVID-19 and LCC symptoms, activity limitations, and healthcare use. Results: Data from 2,466 people from 16 countries in LATAM were analyzed (females = 65.9%; mean age of 39.5 ± 53.3 years). 1,178 (48%) of the respondents had LCC symptoms (≥3 months). These were more likely to have COVID-19 earlier in the pandemic, were older, had no COVID vaccines, had more comorbidities, needed supplementary oxygen, and reported significantly more COVID-19 symptoms during the infectious period. 33% of the respondents visited a primary care provider, 13% went to the emergency department, 5% were hospitalized, 21% visited a specialist, and 32% consulted ≥1 therapist for LCC symptoms mainly extreme fatigue, sleep difficulties, headaches, muscle or joint pain, and shortness of breath with activity. The most consulted therapists were respiratory therapists (15%) and psychologists (14%), followed by physical therapists (13%), occupational therapists (3%), and speech pathologists (1%). One-third of LCC respondents decreased their regular activities (e.g., work, school) and 8% needed help with activities of daily living (ADLs). LCC respondents who reduced their activities reported more difficulty sleeping, chest pain with activity, depression, and problems with concentration, thinking, and memory, while those who needed help with ADLs were more likely to have difficulty walking, and shortness of breath at rest. Approximately 60% of respondents who experienced activity limitations sought a specialist and 50% consulted therapists. Conclusions and relevance: Results supported previous findings in terms of the LCC demographics, and provided insight into LCC impact on patients’ activities and healthcare services used in LATAM. This information is valuable to inform service planning and resource allocation in alignment with the needs of this population.“Publicación Acceso abierto Association between the Risk of Preterm Birth and Low Birth Weight with Periodontal Disease in Pregnant Women: An Umbrella Review(MDPI, 2023-03-07) Padilla-Cáceres, Tania; Arbildo-Vega, Heber Isac; Caballero-Apaza, Luz; Cruzado-Oliva, Fredy; Mamani-Cori, Vilma; Cervantes-Alagón, Sheyla; Munayco-Pantoja, Evelyn; Panda, Saurav; Vásquez-Rodrigo, Hernán; Castro-Mejía, Percy; Huaita-Acha, DelsiBackground: The purpose of this review is to determine the association between the risk of preterm birth and low birth weight in newborns and periodontal disease in pregnant women. Methods: A bibliographic search was carried out until November 2021 in the following biomedical databases: PubMed/Medline, Cochrane Library, Scopus, EMBASE, Web of Science, Scielo, LILACS and Google Scholar. Studies reporting the association between the risk of preterm birth and low birth weight in newborns with periodontal disease in pregnant women, which were systematic reviews, in English and without time limits were included. AMSTAR-2 was used to assess the risk of the included studies, and the GRADEPro GDT tool was used to assess the quality of the evidence and the strength of the recommendation of the results. Results: The preliminary search yielded a total of 161 articles, discarding those that did not meet the selection criteria, leaving only 15 articles. Seven articles were entered into a meta-analysis, and it was found that there is an association between the risk of preterm birth and low birth weight in newborns with periodontal disease in pregnant women. Conclusions: There is an association between the risk of preterm birth and low birth weight in newborns with periodontal disease in pregnant women.Publicación Acceso abierto Impact of COVID-19 on quality of life in Peruvian older adults: construct validity, reliability and invariance of the COV19-Impact on Quality of Life (COV19-QoL) measurement(SPRINGER INT PUBL AG, 2023-05-22) Caycho-Rodríguez, Tomás; Carbajal-León, Carlos; Vilca, Lindsey W; Reyes-Bossio, Mario; Gallegos , Miguel; Carranza Esteban , Renzo; Noe-Grijalva, Martin; Arias Gallegos, Walter L; Delgado-Campusano, Mariel; Muñoz-Del-Carpio-Toia, ÁguedaThe aim of the present study was to translate into Spanish and evaluate the psychometric evidence of the Impact on Quality of Life (COV19-QoL) applied to a sample of Peruvian older adults (N = 298; 58.1% women, 41.9% men, mean age 65.34 years [SD = 11.33]). The study used techniques from the Classical Test Theory (CTT) and Item Response Theory (IRT). The findings confirmed the single factor structure of the COV19-QoL, high internal consistency reliability, measurement invariance by gender, and all items demonstrated adequate discrimination and difficulty indices. In this sense, the items allow adequate discrimination between low, medium and high levels of the impact of the COVID-19 pandemic on quality of life. In addition, a greater perceived impact of the pandemic on quality of life is necessary to answer the higher response options of the COV19-QoL. In conclusion, the COV19-QoL is a valid measurement scale of the impact of the COVID-19 pandemic on the quality of life of Peruvian older adults.Publicación Acceso abierto Latin American perceptions of fear and exaggeration transmitted by the media with regard to COVID-19: frequency and association with severe mental pathologies(FRONTIERS MEDIA SA, 2023-05-17) Mejia, Christian R.; Aveiro-Róbalo, Telmo Raul; Garlisi Torales, Luciana Daniela; Castro Hidalgo, Verónica Alejandra; Valeriano, Jhino; Ibarra-Montenegro, David Alfonso; Conde-Escobar, Aram; Sánchez-Soto, Fernanda; Canaviri-Murillo, Yuliana; Oliva-Ponce, María; Serna-Alarcón, Victor; Vilela-Estrada, Martín A.; Arias-Chávez, DennisIntroduction: The COVID-19 pandemic contributed to the spread of abundant misinformation by the media, which caused fear and concern. Objective: To determine the association between the pathologies of the mental sphere and the perceptions of fear and exaggeration transmitted by the media with respect to COVID-19 in Latin America. Methodology: The present study has an analytical cross-sectional design that is based on a validated survey to measure fear and exaggeration transmitted by the media and other sources (Cronbach’s α: 0.90). We surveyed more than 6,000 people, originally from 12 Latin American countries, who associated this perceived exaggeration with stress, depression, and anxiety (measured through DASS-21, Cronbach’s α: 0.96). Results: Social networks (40%) or television (34%) were perceived as the sources that exaggerate the magnitude of the events. In addition, television (35%) and social networks (28%) were perceived as the sources that generate much fear. On the contrary, physicians and health personnel are the sources that exaggerated less (10%) or provoked less fear (14%). Through a multivariate model, we found a higher level of global perception that was associated with whether the participant was older (p = 0.002), had severe or more serious anxiety (p = 0.033), or had stress (p = 0,037). However, in comparison with Peru (the most aected country), there was a lower level of perception in Chile (p < 0.001), Paraguay (p = 0.001), Mexico (p < 0.001), Ecuador (p = 0.001), and Costa Rica (p = 0.042). All of them were adjusted for gender and for those having severe or major depression. Frontiers in Psychology 01 frontiersin.or Mejia et al. 10.3389/fpsyg.2023.1037450 Conclusion: There exists an association between some mental pathologies and the perception that the media does not provide moderate information.Publicación Acceso abierto Association between childhood trauma and mental health disorders in adolescents during the second pandemic wave of COVID-19, Chiclayo-Peru(FRONTIERS MEDIA SA, 2023-06-22) Valladares-Garrido, Mario J. ; León-Figueroa, Darwin A. ; Dawson, Franccesca M. ; Burga-Cachay, Stefany C. ; Fernandez-Canani, Maria A. ; Failoc-Rojas, Virgilio E. ; Pereira-Victorio, César Johan ; Valladares-Garrido, Danai ; Inga-Berrospi, FiorellaIntroduction: The COVID-19 pandemic has significantly affected mental health, with children and adolescents being particularly vulnerable. Evidence on the association between childhood trauma and mental health outcomes in schoolchildren during the pandemic is limited. This study aimed to evaluate this relationship in Chiclayo city, northern Peru, during the second wave of COVID-19. Methods: A cross-sectional secondary data study was conducted, measuring childhood trauma using the Marshall’s Trauma Scale, depressive symptomatology (PHQ-9), and anxiety symptomatology (GAD-7). Additional variables assessed were alcohol use (AUDIT), resilience (abbreviated CD-RISC), and socio-educational data. Prevalence ratios were estimated using generalized linear models. Results: Among 456 participants, 88.2% were female, with a mean age of 14.5 years (SD: 1.33). Depressive symptomatology prevalence was 76.3% (95%CI: 72.14– 80.15) and increased by 23% in schoolchildren with childhood trauma (PR: 1.23; 95%CI: 1.10–1.37). Factors positively associated with depressive symptomatology included increasing age, seeking mental health help during the pandemic, and severe family dysfunction. Anxiety symptomatology prevalence was 62.3% (95%CI: 57.65–66.75) and increased by 55% in schoolchildren with childhood trauma (PR: 1.55; 95%CI: 1.31–1.85). Anxiety symptomatology was positively associated with mild, moderate, and severe family dysfunction. Conclusion: Schoolchildren exposed to childhood trauma are at increased risk for depressive and anxiety symptoms. Monitoring the impact of the COVID-19 pandemic on adolescent mental health is vital. These findings can assist schools in establishing effective measures to prevent mental health outcomes.Publicación Acceso abierto Antigen-Induced IL-1RA Production Discriminates Active and Latent Tuberculosis Infection(MDPI, 2023-05-25) Sanchez, Cesar; Jaramillo-Valverde, Luis; Capristano, Silvia; Solis, Gilmer; Soto, Alonso; Valdivia-Silva, Julio; Poterico, Julio A.; Guio, HeinnerThe IGRA (Interferon Gamma Release Assays) test is currently the standard specific test for Mycobacterium tuberculosis infection status. However, a positive test cannot distinguish between active tuberculosis disease (ATBD) and latent tuberculosis infection (LTBI). Developing a test with this characteristic is needed. We conducted longitudinal studies to identify a combination of antigen peptides and cytokines to discriminate between ATBD and LTBI. We studied 54 patients with ATBD disease and 51 with LTBI infection. Cell culture supernatant from cells stimulated with overlapping Mycobacterium tuberculosis novel peptides and 40 cytokines/chemokines were analyzed using the Luminex technology. To summarize longitudinal measurements of analyte levels, we calculated the area under the curve (AUC). Our results indicate that in vitro cell stimulation with a novel combination of peptides (Rv0849-12, Rv2031c-14, Rv2031c-5, and Rv2693-06) and IL-1RA detection in culture supernatants can discriminate between LTBI and ATBD.Publicación Acceso abierto Frontline Worker Safety in the Age of COVID-19: A Global Perspective(LIPPINCOTT WILLIAMS & WILKINS, 2023-05-10) Kavanagh, Kevin T; Matthias Maiwald, Christine Pontus ; Cimiotti, Jeannie P; Palmieri , Patrick A; Cormier, Lindsay EThe third annual Health Watch USA sm webinar conference assembled 16 speakers from 4 continents who shared information regarding frontline worker safety in the age of COVID-19. The U.S. Bureau of Labor Statistics reported a nearly 4000% increase in workplace illness in 2020 compared with 2019. It is estimated that 2% of the U.S. workforce is not working because of long COVID. In addition, the impact is growing with each surge. After the acute illness, patients are often described as recovered, when in fact many have only survived and are coping with the multisystem impacts of long COVID. Long COVID, including its late cognitive, cardiovascular, embolic, and diabetic complications, disproportionately impacts frontline workers, many of whom are of lower socioeconomic status and represented by ethnic minorities. Natural infection and current vaccines do not provide durable protection for reinfection. Herd immunity is not possible at this time. Although SARS-CoV-2 is unlikely to be eliminated, decreasing spread is imperative to slow the rate of mutations, decrease the number of reinfections, and lower the chances of developing long COVID. The primary mode of spread is through aerosolization. Both routine breathing and talking aerosolizes the virus. With the extremely high infectivity of SARS-CoV-2, it is unlikely that central building ventilation alone will be enough to satisfactorily mitigate spread. Additional safe active air cleaning technology, such as upper-room germicidal UV-C lighting, needs to be deployed. Misinformation and disinformation have inhibited response effectiveness. Examples include downplaying the benefit of well-fitted masks and the risks that COVID-19 and long COVID pose to children, along with believing children cannot spread the disease. The engagement of local community leaders is essential to educate the community and drive social change to accept vaccinations and other public health interventions. Vaccinations and natural immunity alone are unlikely to adequately prevent community spread and do not provide durable protection against the risk of long COVID. Frontline workers must keep their immunity as high as possible and work in settings with clean air, along with wearing N95 masks when they are in contact with the public. Finally, there needs to be a financial safety net for frontline workers and their families in the event of incapacitation or death from COVID-19.Publicación Acceso abierto SARS-CoV-2 seroprevalence on the north coast of Peru: A cross-sectional study after the first wave(PUBLIC LIBRARY SCIENCE, 2023-06-28) Moyano, Luz M.; Toledo, Angie K.; Chirinos, Jenny; Vilchez Barreto, Percy Mc Quen; Cavalcanti, Sofia; Gamboa, Ricardo; Ypanaque, Jhon; Meza, Mauro; Noriega, Sheilla; Herrera, Victor; Bazan, Edgar; Requena, Alexandra; Silva, Henry; Burgos, Harold; León-Jimenez, FrancoDuring the first wave, COVID-19 had devastating effects on developing countries like Peru, which reported more than 900,000 cases of the disease and more than 36,000 confirmed deaths from it. The informal settlements are counted in COVID-19 regional statistics, but they are very different from the rest of the region in terms of sanitation, access to water and sewage, housing conditions, and others. To make good decisions about public health, it is important to understand how the disease is spread in informal settlements. We did an observational, cross-sectional study in Puerto Pizarro, a remote port village in Tumbes, from November 11, 2020, to November 30, 2020, to assess the seroprevalence of COVID-19 after the first wave, as well as the sociodemographic factors and symptoms linked to a positive COVID-19 antibody lateral flow test. 1391 people older than 2 years old were given census and symptom questionnaires. They were also tested for the presence of anti-SARS-CoV-2 antibodies (IgG and IgM) in their blood. This study shows an adjusted seroprevalence of 24.82 percent (95% CI 22.49–27.25) posterior to the first wave of COVID-19 in Tumbes. Women had higher adjusted seroprevalence (28.03% vs. 21.11% [95% CI 24.83–31.41], p = 0.002). Extrapolating our adjusted prevalence of 24.82 per 100 persons to Tumbes (N = 251,541), 62,432 people were infected during the first wave, which is too high for adequate primary care in health institutions. Puerto Pizarro’s causespecific mortality rate was 198.49 per 100,000 inhabitants (deaths documented between May and December 2020), which was higher than Tumbes’ up to December 2020 (137.6 per 100,000 inhabitants). The presence of mostly symptomatic patients at health care facilities, the limited use of social networks, the scarce availability of eHealth technologies in government institutions, unused emergency telephone numbers, and the fear of dying if referred to the hospital may have led to underreporting cases. Participation of the community in epidemiological surveillance strategies is critical to assisting the Ministry of Health in the future success of the establishment of an eHealth surveillance monitoring program.Publicación Acceso abierto Preliminary Study of Bioelectricity Generation Using Lettuce Waste as Substrate by Microbial Fuel Cells(MDPI, 2023-06-30) Rojas-Villacorta, Walter; Rojas-Flores, Segundo; Benites, Santiago M.; Nazario-Naveda, Renny; Romero, Cecilia V.; Gallozzo-Cardenas, Moisés; Delfín-Narciso, Daniel; Díaz, Félix; Murga-Torres, EmzonAgricultural waste negatively impacts the environment and generates economic difficulties for agro-industrial companies and farmers. As a result, it is necessary for an eco-friendly and sustainable alternative to managing this type of waste. Therefore, the research aimed to investigate lettuce waste as an alternative substrate to generate bioelectricity in single-chamber microbial fuel cells (scMFCs). It was possible to report voltage and electric current peaks of 0.959 ± 0.026 V and 5.697 ± 0.065 mA on the fourteenth day, values that were attained with an optimum pH of 7.867 ± 0.147 and with an electrical conductivity of 118.964 ± 8.888 mS/cm. Moreover, as time passed the values began to decline slowly. The calculated value of maximum power density was 378.145 ± 5.417 mW/cm2 whose current density was 5.965 A/cm2 , while the internal resistance reported using Ohm’s Law was 87.594 ± 6.226 Ω. Finally, it was possible to identify the Stenotrophomonas maltophilia bacterium (99.59%) on a molecular scale, as one of the microorganisms present in the anodic biofilm. The three microbial fuel cells were connected in series and demonstrated that they were capable of lighting an LED bulb, with a voltage of 2.18 V.Publicación Acceso abierto Fear of COVID-19, risk perception and preventive behavior in health workers: a cross-sectional analysis in middle-income Latin American countries(FRONTIERS MEDIA SA, 2023-06-15) Bonilla-Asalde, César Antonio; Rivera-Lozada, Oriana ; Ipanaqué-Zapata, Miguel; Siprian Castro-Alzate, Elvis ; Pacheco-Lopez, Robinson ; Rivera-lozada, Isabel Cristina ; Chong, Félix ; Ramírez Sagastume, LucreciaThe aim of this study was to examine the association between fear of COVID-19 and risk perception with preventive behavior in health professionals from four Latin American countries. An analytical cross-sectional study was conducted. Health professionals with on-site care in Colombia, Ecuador, Guatemala, and Peru were surveyed. Information was collected through an online self-report questionnaire. The main variables were preventive behavior as the dependent variable and fear of COVID-19 and risk perception as independent variables. Linear regression was used, and unstandardized beta coefficient and value of ps were calculated. Four hundred and thirty-five health professionals were included, the majority were aged 42 years or older (45.29, 95%CI: 40.65–50.01) and female (67.82, 95%CI: 63.27–72.05). It was shown that the greater the fear of COVID-19, the greater the preventive behavior of COVID-19 infection (B = 2.21, p = 0.002 for total behavior; B = 1.12, p = 0.037 for additional protection at work; B = 1.11, pPublicación Acceso abierto When COVID-19 strikes mental health: a measurement analysis of reassurance seeking behavior scale in Peruvian population(FRONTIERS MEDIA SA, 2023-04-17) Manrique-Millones, Denisse; García-Serna, Jackeline; Castillo-Blanco, Ronald; Fernández-Ríos, Nataly; Lizarzaburu-Aguinaga, Danny Alonso; Parihuamán-Quinde, Geraldina Rebeca; Villarreal-Zegarra, DavidBackground: The long-lasting impact of the COVID-19 pandemic cannot be overstated. To combat its dire consequences, some screening measures have been hastily developed and require robust verification to explore their adequacy across different groups. The present research study aimed to analyze measurement invariance by sociodemographic characteristics of the Coronavirus Reassurance Seeking Behavior Scale (CRSB) in Peruvian adults. Methods: A total of 661 participants completed The Coronavirus Reassurance Seeking Behavior Scale (CRSB), the Coronavirus Anxiety Scale (CAS), and sociodemographic information a subgroup filled in the Patient Health Questionnaire (PHQ-9). Reliability and measurement invariance across sociodemographic characteristics were analyzed. Likewise, associations with depression and dysfunctional coronavirus anxiety were examined. Results: Results showed that the single factor structure of the CRSB with correlated errors fitted the data adequately and the instrument was invariant across gender, age, and loss of a significant relative to COVID-19. In addition, significant associations with depressive symptoms and dysfunctional anxiety were found. Conclusion: The findings of the present study suggest that the Coronavirus Reassurance Seeking Behaviors Scale is invariant across different sociodemographic characteristics.Publicación Acceso abierto Use of Kiwi Waste as Fuel in MFC and Its Potential for Use as Renewable Energy(MDPI, 2023-04-12) Rojas-Flores, Segundo; De La Cruz-Noriega, Magaly; Cabanillas-Chirinos, Luis; Benites, Santiago M.; Nazario-Naveda, Renny; Delfín-Narciso, Daniel; Gallozzo-Cardemas, Moisés; Murga-Torres, Emzon; Rojas-Villacorta, Walter; Díaz, FelixThis research aimed to use kiwi waste as fuel to generate bioelectricity through microbial fuel cells. It was possible to generate an electrical current and voltage peaks of 3.807 ± 0.102 mA and 0.993 ± 0.061 V on day 11, showing an electrical conductivity of 189.82 ± 3.029 mS/cm and an optimum operating pH of 5.966 ± 0.121. The internal resistance of the cells was calculated using Ohm’s Law, resulting in a value of 14.957 ± 0.394 Ω, while the maximum power density was 212.68 ± 26.84 mW/m2 at a current density of 4.506 A/cm2. Through the analysis of the FTIR spectra carried out on the substrate, a decrease in the characteristic organic peaks was observed due to their decomposition during the electricity-generation process. In addition, it was possible to molecularly identify the bacteria Comamonas testosteroni, Sphingobacterium sp., and Stenotropho-monas maltophila adhered to the anodized biofilm. Finally, the capacity of this residue to generate bioelectricity was demonstrated by lighting an LED bulb with a voltage of 2.85 V.Publicación Acceso abierto Translation and validation of the WHO-5 General well-being index into native language Quechua of the Peruvian South(CELL PRESS, 2023-06-01) Carranza Esteban, Renzo Felipe; Mamani-Benito, Oscar; Cjuno, Julio; Tito-Betancur, Madona; Lingán-Huamán, Susana K; Arias-Chávez, DennisTo translate and validate the WHO-5 General Well-being Index for the people of the Peruvian South, a cross-sectional instrumental study was carried out with the voluntary participation of 186 people of both sexes between the ages of 18 and 65 years (M = 29.67 years old; SD = 10.94) living in the south region of Peru. The validity evidence was assessed based on the content using Aiken's coefficient V according to the internal structure through a confirmatory factor analysis, and reliability was calculated through Cronbach's alpha coefficient. The expert judgment was favorable for all items (V > 0.70). The unidimensional structure of the scale was confirmed (χ2 = 10.86, df = 5, p = 0.05; RMR = 0.020; GFI = 0.980; CFI = 0.990; TLI = 0.980 y RMSEA = 0.080), and it presents a suitable reliability range (α = > 0.75). This shows that the WHO-5 General Well-being Index for the people of the Peruvian South is a valid and reliable scale.Publicación Acceso abierto Explanatory Model on Academic Self-Efficacy in Engineering Students: Role of Anxiety, Dysthymia, and Negative Affect(INT ASSOC ONLINE ENGINEERING, 2023-07-06) Yupanqui-Lorenzo, Daniel E.; Olivera-Carhuaz, Edith S.; Reynaga Alponte, Antonio A.; Pulido-Capurro, Víctor; Carbajal-León, Carlos; Cardoza Sernaqué, Manuel AntonioStudents in engineering tend to be loners, making interpersonal relationships and mental health issues more likely to arise. The COVID pandemic caused university students to experience anxiety and depression, which affected their academic performance and self-esteem. However, students’ mental health was rarely evaluated after the pandemic, especially engineering students, who showed higher levels of depression than students from other disciplines. The present study aims to establish an explanatory model of academic self-efficacy based on factors related to mental health, such as anxiety, depression, and negative emotions. The method used was quantitative cross-sectional, and a structural equation modeling was used. A sample of 561 students (54.4% males and 45.6% females) was analyzed. Instruments to measure self-efficacy, negative affect, depression, and anxiety, previously validated and with adequate reliability, were applied. The results showed that a state of anxiety affects academic self-efficacy negatively and directly; depression and negative affect indirectly affect academic self-efficacy mediated by a state of anxiety. These results show that a student with depression problems and a predominance of negative emotions is vulnerable to present anxiety in an academic setting. This anxiety causes his efficacy beliefs to decrease. As a result, he does not feel capable of facing academic challenges.Publicación Acceso abierto Factores asociados a la capacidad científica-académica básica en estudiantes de medicina de Latinoamérica(UNIV ANTIOQUIA, FAC MED, 2022-09-26) Valladares-Garrido, Mario J.; Serrano, Felipe T.; Guarnizo-Llacsahuanga, Jose; Rivera-Pinto, Alix Ximena; Valladares-Garrido, Danai; Mejía, Christian R.“Introducción: existe evidencia limitada en cuanto al entrenamiento estudiantil en capacidades científicas y académicas esenciales para la formación médica.

Se estimaron razones de prevalencia (RP) utilizando modelos lineales generalizados multinivel de efectos mixtos (MEGLM). Se realizó un modelo anidado para evaluar la inclusión de covariables en el modelo parsimónico utilizando LRTest. Resultados: de 11.587 estudiantes, solo el 1,4 % presentó capacidad básica científica-académica. Los factores asociados de forma positiva fueron la procedencia de universidad privada (RP: 4,85, p < 0,001), estar afiliado a una sociedad científica estudiantil (SOCEM) (RP: 3,20, p < 0,001), pertenecer a grupos de investigación (RP: 2,97, p < 0,001) y ser parte de más de un grupo extracurricular (RP: 4,29, p = 0,012). Los factores asociados de forma negativa fueron proceder de Bolivia (RP: 0,05, p = 0,005), Argentina (RP: 0,06, p = 0,011) y Perú (RP: 0,14, p < 0,001). Conclusión: existe un pobre entrenamiento en capacidades científicas-académicas básicas en estudiantes de medicina. Proceder de universidad privada y estar afiliado a sociedades científicas o grupos afines se asoció a una mayor frecuencia de adquirir dichas herramientas.“Publicación Acceso abierto Electrochemical Sensitivity Improvement by the Cooperation between Pt and Ru for Total Antioxidant Evaluation in Natural Extracts(MDPI, 2023-05-23) Carvalho Diniz, Gustavo; Rodrigues Pinheiro Gomes, Vinicius Tribuzi; De Assis, Marcelo; Figueroa, Santiago José Alejandro; Ferreira Torquato, Igor; De Freitas Borge, Luiz Gustavo; Aguilar Vitorino, Hector; Batista de Lima, Roberto; Suller Garcia, Marco Aurélio; De Araujo Rodrigues, IsaídeHerein, a straightforward electrochemical method was used to evaluate the total phenolic antioxidant capacity in natural extracts prepared from pomegranate, hibiscus, and pitaya. In light of this, the well-known electrochemical index (EI), a screening protocol for natural antioxidant properties evaluation, was determined using differential pulse voltammetry. Initially considering rutin and catechin as standards, we found that the system’s sensitivity greatly increased by using platinum (Pt) and platinum/ruthenium (Pt/Ru) nanoparticles (NPs) immobilized on Vulcan XC-72 to modify screen-printed carbon electrodes (SPCEs). When such modifications were applied to natural fruit/plant extracts, their electrochemical ability proved highly superior to the bare SPCE, even considering a very small amount of materials for electrode preparation. However, with an optimized ratio, the bimetallic counterpart was more sensitive to detection. When the pomegranate extract was used, for example, EI values of 52.51 ± 6.00 and 104.79 ± 6.89 µA/V were obtained using Pt and Pt/Ru (with an optimized ratio) electrocatalysts, showing the remarkable sensitivity increase obtained in our bimetallic protocol. Thus, based on physicochemical and electrochemical characterizations, we found that the ruthenium content was essential for the achievements. In due course, XPS analysis suggested that the Pt2+/Pt0 species ratio could have improved the system’s sensitivity, which significantly changed when ruthenium was used in the material.Publicación Acceso abierto Green Energy Generated in Single-Chamber Microbial Fuel Cells Using Tomato Waste(MDPI, 2023-07-03) Rojas-Flores, Segundo; De La Cruz-Noriega, Magaly; Cabanillas-Chirino, Luis; Benites, Santiago M.; Nazario-Naveda, Renny; Delfín-Narciso, Daniel; Gallozzo-Cardena, Moisés; Murga-Torres, Emzon; Rojas-Villacorta, Walter; Diaz, FélixThis research used tomato waste as a substrate (fuel) in Single Chamber-Microbial Fuel Cells (scMFC) on a small scale. The electrochemical properties were monitored, the functional groups of the substrate were analyzed by Fourier Transform Infrared Spectrophotometry (FTIR) and a microbiological analysis was performed on the electrodes in order to identify the microorganisms responsible for the electrochemical process. The results show voltage peaks and an electrical current of 3.647 ± 0.157 mA and 0.957 ± 0.246 V. A pH of 5.32 ± 0.26 was measured in the substrate with an electrical current conductivity of 148,701 ± 5849 mS/cm and an internal resistance (Rint) of 77. 517 ± 8.541 Ω. The maximum power density (PD) displayed was 264.72 ± 3.54 mW/cm2 at a current density (CD) of 4.388 A/cm2. On the other hand, the FTIR spectrum showed a more intense decrease in its peaks, with the compound belonging to the phenolic groups being the most affected at 3361 cm−1. The micrographs show the formation of a porous biofilm where molecular identification allowed the identification of two bacteria (Proteus vulgaris and Proteus vulgaris) and a yeast (Yarrowia lipolytica) with 100% identity. The data found show the potential of this waste as a source of fuel for the generation of an electric current in a sustainable and environmentally friendly way, generating in the near future a mechanism for the reuse of waste in a beneficial way for farmers, communities and agro-industrial companies.Publicación Acceso abierto The Age of Young Nurses Is a Predictor of Burnout Syndrome during the Care of Patients with COVID-19(MDPI, 2023-04-17) Moya-Salazar, Jeel; Buitrón, Liliana A.; Goicochea, Eliane A.; Salazar, Carmen R.; Moya-Salazar, Belén; Contreras-Pulache, HansBackground: Burnout Syndrome (BS) is a work fatigue phenomenon that leads to physical exhaustion during care work, and there could be an increase in the proportion of nurses affected during the COVID-19 pandemic, especially in those caring for infected patients. We aimed to determine BS in nurses during the COVID-19 pandemic. Methods: An observational study was conducted on 100 nurses over the age of 18 and working in COVID-19 medical units in 2021. The 22-item Maslach Burnout Inventory questionnaire was used to estimate BS, and differences between age groups, gender, work time, and previous infection were estimated. Results: The majority of nurses (mean 30 ± 5.5 years) were women (78%), and the most frequent working time was from 1 to 10 years (58%). A total of 88% of the nurses had moderate BS, affecting more males, aged between 20 and 30 years, and without previous infection. The youngest age group, 20–30 years, presented the highest mean BS with 53.8 (SD 4.18) points (95% CI: 52.79 to 54.8), showing differences with older nurses (p < 0.05). Prediction analysis showed that only age was a significant predictor for the development of SB (p < 0.001). Conclusions: BS negatively impacts young nurses during the care of COVID-19 patients, so strategies should be promoted to ensure a better working environment. Improving the workspace can include self-care strategies, changes in the system and work organization, an improvement of interpersonal relationships, and risk prevention.
