Prevalencia de trastornos temporomandibulares y factores asociados en estudiantes de una universidad privada de Lima-Perú(Academia Nacional de Medicina, 2022-10-01)Introduction: Temporomandibular disorders (TMDs) are musculoskeletal and neuromuscular alterations that affect the temporomandibular joint, masticatory muscles, and contiguous structures. A high prevalence of TMD has been reported in university students, and it may also be associated with neck pain and emotional disturbances. The objective is to determine the prevalence and factors associated with TMD in university students. M ethods: An analytical cross-sectional observational study was conducted. The population was university students who have completed in 2021, aged between 18 and 35 years. The Fonseca Simplified Anamnestic Index Questionnaire, DASS-21, Nordic Questionnaire, and general data questionnaire were used. Results: 378 university students were included in the study, 73.6 % had TMD and 59.8 % had cervical pain in the last 7 days. 55.6 %, 71.4 %, and 65.6 % presented stress, anxiety, and depression, respectively. A significant association was found between TMD and cervical pain in the last 7 days (RPa=1.28, CI95 % 1.11 to 1.47, p=0.001), with anxiety (RPa=1.24, CI95 % 1.02 to 1.52, p=0.033) and with female sex (RPa=1.18, CI95 % 1.02 to 1.37, p=0.025). On the contrary, no association was found between TTM and the stress and depression variables. Conclusion: 73.6 % of university students had TMD, and it was also shown that cervical pain in the last 7 days and anxiety were associated with TMD. No relationship was found between stress and depression with TMD.Acceso abierto

A cross-sectional study to assess the level of satisfaction with virtual education in Peruvian medical students(Frontiers Media S.A., 2022-10-05)Objectives: Education has totally changed in the context of the pandemic. Therefore, the objective of the present study was to evaluate the factors associated with the level of satisfaction with virtual education in Peruvian medical students during COVID-19. Methods: Analytical and cross-sectional study, based on an online survey of students nationwide. We use previously validated instruments to measure the level of satisfaction and stress (EPP-10-c) of students with virtual education. For the associated factors, adjusted prevalence ratios (PR) were estimated using Poisson regression. Results: Of the 1,878 students surveyed, the median age was 21 years, 57.8% (1,086) were women, 34.8% (654) had a high level of satisfaction with virtual education and 10.7% (202) presented high levels of stress. The factors associated with a low level of satisfaction were attending the fifth year of study, the partial and non-virtual adaptation of the university to virtual education, and a high level of stress. On the other hand, the factors associated with a high level of satisfaction were the education platform used and the study method used. Conclusion: Seven out of 10 students presented a low level of satisfaction with virtual education, 1 out of 10 presented a high level of stress. The factors associated with the low level of satisfaction were attending the fifth year of study, the non-virtual and partial adaptation of the university to virtual education, and the high level of stress.Acceso abierto

University teachers' self-perception of digital research competencies. A qualitative study conducted in Peru(Frontiers Media S.A., 2022-10-06)Previous research warns about the limitations that some university teachers in Ibero-America have in relation to digital research competencies. The objective of this research was to analyze the research competencies from the university teacher's self-perception, contrasted with the classroom evaluation. The study had a qualitative approach. Interviews were conducted via the Zoom virtual platform, and recordings (of an average of 4 h each) of classes delivered by 10 teachers with an average age of 58 years old, in charge of scientific research courses at the postgraduate level in Peruvian universities were analyzed. The instruments used included an in-depth interview guide and a checklist. The results show that university teachers perceive themselves as specialists in the area of research, however, they present limitations when transmitting knowledge during the teaching-learning process. There is evidence of a lack of pedagogy, as well as limitations in the use of digital resources and technological tools due to their resistance to change. The conclusions reveal that it is key to make teachers aware of the paradigm shift, with a teaching that includes as digital competencies: knowing how to create and manipulate data, knowing how to use programs and information systems, knowing how to socialize and collaborate in digital environments, knowing how to exercise and respect a digital citizenship, knowing how to manage knowledge assertively, and, as we propose in this paper, knowing how to be a researcher in a digital environment.Acceso restringido temporalmente

Relationship between job satisfaction, burnout syndrome and depressive symptoms in physicians: a cross-sectional study based on the employment demand-control model using structural equation modelling(BMJ Publishing Group, 2022-10-19)Objective To evaluate the relationship between job satisfaction, burnout syndrome (BS) and depressive symptoms (DS) based on the job demand-control framework model on a nationally representative sample of physicians working in the Peruvian Health System. Setting We carried out a secondary data analysis of the National Survey of Satisfaction of Users in Health 2016 in Peru. Primary and secondary outcome measures Our study assessed the development of the predictive model and had two parts: (1) to evaluate the association among the variables based on the job demand-control framework, and (2) to assess the proposed model acceptability using the structural equation modelling approach to estimate goodness-of-fit indices (GOFIs). Participants We excluded physicians older than 65 years, who did not report income levels or who had missing data related to the workplace. Thus, we analysed 2100 participants. Results The prevalence of DS was 3.3%. Physicians' work-related illnesses had more probability to result in DS (prevalence ratio=2.23). DS was moderately related to BS dimensions (r>0.50); nevertheless, the relationships between DS and the three job satisfaction scales were weak (r<0.30). The first predictive model based on the variables, DS, BS and job satisfaction, had low GOFIs (comparative fit index (CFI)=0.883; root mean square error of approximation (RMSEA)=0.125). In a second evaluation, we used models with correlated errors obtaining optimal GOFIs (CFI=0.974; RMSEA=0.060). Conclusions Our study identified a stable model to explain the relationship between job satisfaction, BS and DS among physicians. The results are consistent with the job demand-control framework. They could be applied to decision-making in occupational contexts in Latin American low/middle-income countries.Acceso abierto

Physical abuse in childhood and intimate partner violence in Peruvian women: A population-based survey, 2019(Academic Press Inc., 2022-11-01)Intimate partner violence (IPV) is a global health problem and a violation of individual rights. The objective of this study was to assess the association between physical child abuse and current IPV in women of childbearing age in Peru. An analytical cross-sectional analysis of the data from the 2019 Demographic and Family Health Survey was carried out. IPV was constituted by emotional, physical and sexual violence, while physical child abuse was constructed from variables related to physical punishment that women of childbearing age experienced during childhood. Poisson's family generalized linear models were used for the crude and adjusted analyses to determine the association between physical child abuse and IPV. Data from a total of 21,518 women of childbearing age were included. 67.1% of women experienced physical abuse in childhood, while 57.7% experienced intimate partner violence. After adjusting for the characteristics of the woman, the partner or husband, marriage or relationship and the home, it was observed that having experienced physical abuse during childhood increased the probability of experiencing emotional (adjusted prevalence ratio [aPR] 1.15; 95% confidence interval [CI]: 1.09–1.21), physical (aPR 1.33; 95% CI: 1.20–1.47), sexual (aPR 1.57; 95% CI: 1.26–1.96) and any type of violence (aPR 1.15; 95% CI: 1.09–1.21) in adulthood. In conclusion, physical abuse during childhood is a public health issue in Peru. This study shows that women aged 15 to 49 who experienced physical abuse in childhood are more likely to experience intimate partner violence.Acceso abierto

Antiviral Treatment against Monkeypox: A Scoping Review(MDPI, 2022-11-01)uring the COVID-19 pandemic, the increase in reports of human monkeypox virus infection cases spreading in many countries outside Africa is a major cause for concern. Therefore, this study aimed to explore the evidence of antiviral pharmacotherapy available for the treatment of adult patients with monkeypox. A scoping review of the literature was conducted using PubMed, Scopus, Web of Science, Embase, and CENTRAL databases until 12 September 2022. The key search terms used were “monkeypox” and “treatment”. A total of 1927 articles were retrieved using the search strategy. After removing duplicates (n = 1007) and examining by title, abstract, and full text, 11 studies reporting case reports of monkeypox with antiviral treatment were included, detailing the number of monkeypox cases, clinical manifestations, number of participants with antiviral treatment, history of sexually transmitted diseases, method of diagnosis, location of skin lesions, drugs used in antiviral treatment, route of administration, and outcome. A total of 1281 confirmed cases of monkeypox have been reported, of which 65 monkeypox cases had antiviral treatment distributed most frequently in the United States (n = 30), the United Kingdom (n = 6), and Spain (n = 6). Of the total cases, 1269 (99.1%) were male with an age range of 18 to 76 years, and 1226 (95.7%) had a sexual behavior of being men who have sex with men. All confirmed cases of monkeypox were diagnosed by reverse transcriptase polymerase chain reaction (RT-PCR). The most frequent clinical manifestations were skin lesions, fever, lymphadenopathy, headache, fatigue, and myalgia. The most frequent locations of the lesions were perianal, genital, facial, and upper and lower extremities. The most commonly used drugs for antiviral treatment of monkeypox were: tecovirimat, cidofovir, and brincidofovir. All patients had a complete recovery. According to current evidence, the efficacy and safety of antiviral drugs against monkeypox is of low quality and scarce.Acceso abierto

Is There an Association between Being a Victim of Physical Violence by Intimate Partner and Binge Drinking in Men and Women? Secondary Analysis of a National Study, Peru 2020(MDPI, 2022-11-01)The relationship between being a victim of physical violence by an intimate partner and binge drinking (BD) is a poorly explored line of research, especially in men. To determine the association between being a victim of physical violence by an intimate partner and BD in men and women in Peru in 2020, a secondary analytical cross-sectional study was conducted using the Demographic Health Survey. BD was categorized according to the Center of Disease Control definition for men and women, based on the type and amount of alcoholic beverage ingested. Physical violence was based the report of being hit with any part of the body or an object, by their intimate partner. To identify the association, a multivariable general linear model of the family and link log Poisson was used. The results were presented as prevalence ratios (PRs). In the adjusted models stratified by sex, a 90% greater likelihood of BD was found in male victims and an 80% higher probability among female victims (PRa 1.9, 95%CI 1.3;2.7, p < 0.001 vs. PRa 1.8, CI95% 1.1; 2.8, p = 0.013, respectively). An association was found between physical violence by an intimate partner and BD in the Peruvian population older than 15 years, in both men and women.Acceso abierto

Lymphocyte-to-Monocyte Ratio and Clinical Outcomes in Cholangiocarcinoma: A Systematic Review and Meta-Analysis(MDPI, 2022-11-01)Lymphocyte-to-Monocyte ratio (LMR) has shown an association with survival outcomes in several oncological diseases. This study aimed to evaluate the association between LMR and clinical outcomes for cholangiocarcinoma patients. A systematic review and meta-analysis were performed to assess the association between LMR values and overall survival (OS), disease-free survival (DFS), recurrence-free survival (RFS) and time to recurrence (TTR) in cholangiocarcinoma patients. We used Hazard ratio (HR) and their 95% confidence interval (CI) as a measure of effect for the random effect model meta-analysis. The Newcastle–Ottawa Scale was used for quality assessment. The Egger test and funnel plot were developed for approaching publication bias. A total of 19 studies were included in this study (n = 3860). The meta-analysis showed that cholangiocarcinoma patients with low values of LMR were associated with worse OS (HR: 0.82; 95% CI: 0.71–0.96; I2 = 86%) and worse TTR (HR: 0.71; 95% CI: 0.58–0.86; I2 = 0%). DFS and RFS also were evaluated; however, they did not show statistically significant associations. Low LMR values were associated with a worse OS and TTR.Acceso abierto

Acceptance towards Monkeypox Vaccination: A Systematic Review and Meta-Analysis(MDPI, 2022-11-01)Vaccination it is considered a vital strategy in order to mitigate monkeypox by protecting from severe disease and helping in reduction of hospitalisations. In this sense, this study aims to estimate the global prevalence of vaccination acceptance against monkeypox. We conducted a systematic review with a comprehensive search strategy for the following databases: PubMed, Scopus and Web of Science. A random-effect model meta-analysis was carried out using observational studies assessing the intention of vaccines against monkeypox from multiple continents. The quality assessment was developed using the Newcastle-Ottawa Scale adapted for cross-sectional studies. In addition, a subgroup analysis by study location and population and a sensitivity analysis was developed.Eleven cross-sectional studies were included. A total of 8045 participants were included. The pooled prevalence of monkeypox vaccination acceptance in all participants was 56.0% (95%CI: 42.0–70.0%). In the subgroup analysis of monkeypox vaccine acceptance according to continents, the prevalence of vaccine acceptance was 50.0% (95%CI: 24.0–76.0%) in Asian countries and 70.0% (95%CI: 55.0–84.0%) in European countries. The prevalence of vaccine acceptance was 43.0% (95%CI: 35.0–50.0%) in the general population, 63.0% (95%CI: 42.0–70.0%) in healthcare workers, and 84.0% (95%CI: 83.0–86.0%) in the LGBTI community. Despite the high prevalence of monkeypox vaccination acceptance in the LGBTI community found in our study, vaccination acceptance from healthcare workers and the general population are lower. Governments could use these results for planning, developing or promoting vaccination strategies and public health policies focused on these populations.Acceso abierto

Gender Differences of University Students in the Online Teaching Quality and Psychological Profile during the COVID-19 Pandemic(MDPI, 2022-11-01)With the arrival of COVID-19, educational systems have had to adapt to the social and health situation immediately. This led to the appearance of the asynchronous teaching model. Throughout the pandemic, at the educational level, we can distinguish three phases, eminently online, hybrid, and finally, face-to-face. However, the perception of educational quality in these three educational moments, taking into account the psychometric profile and gender, has not been studied. Thus, 1093 university students from Ibero-American countries were analyzed. Through a questionnaire, demographic, academic, and psychological variables were analyzed at three moments during the evolution of the pandemic. Data suggest that, during the lockdown phase, while teaching was eminently online, students presented higher levels of stress and higher difficulty of learning; class attendance, convenience, preferred method of learning, grading score, and motivation were lower, compared to other phases of teaching (hybrid and face-to-face). During this period, females presented higher stress levels than males, as well as higher levels of anxiety and loneliness, without gender differences among the other studied variables. During the hybrid and face-to-face phases, male students presented higher values in the results of difficulty learning and demanding activities. No differences were seen regarding motivation, synchronous class attendance, learning level, grades, convenience, or preferred learning method. The results from the present study suggest that, despite the effect of the pandemic on mental health, asynchronous education is postulated as an effective teaching–learning alternative. Yet, a special focus should be given to female students.Acceso abierto

Efficacy and Safety of Topical Application of Olive Oil for Preventing Pressure Ulcers: A Systematic Review and Meta-Analysis of Randomized Controlled Trials(MDPI, 2022-11-01)he purpose was to identify and summarize the existing evidence on the efficacy and safety of the topical application of olive oil for preventing pressure ulcers (PUs). We included only randomized controlled trials (RCTs) involving patients at risk of developing PUs, testing the topical application of olive oil versus other products for PU prevention. We assessed the risk of bias using the RoB 2 tool, and the certainty of the evidence with GRADE. Four RCTs met the eligibility criteria. All studies were judged at a low risk of bias overall. The meta-analysis showed that the clinical efficacy of olive oil for prevention occurs by reducing the incidence of PUs (RR = 0.56, 95% CI = 0.30 to 0.79, I2 = 0%); with no differences in adverse effects, it may be associated with a shorter development time of PUs and shorter hospital stays. The certainty of the evidence assessed by the GRADE approach was moderate and low. The topical application of olive oil is effective and safe in reducing the incidence of PUs compared to other treatments. These findings could provide new insights into olive oil as a preventive and alternative treatment for PUs as it is accessible and inexpensive compared to other products.Acceso abierto

Asociation between nutritional status and depressive symptoms in a Peruvian adult population: A population-based study in Peru(Instituto Nacional de Psiquiatria Ramon de la Fuente, 2022-11-01)Introduction. Among the Peruvian population, the prevalence of overweight and obesity has increased, making it one of the main public health problems. There is also conflicting evidence on the association between increased BMI and depressive symptoms in the adult population. Objective. To determine the association between nutritional status (NS) and depressive symptoms (DS) in the Peruvian population. Method. We conducted a secondary data analysis of the Peruvian Demographic and Family Health Survey (ENDES). We assessed the NS according to body mass index (BMI), grouped into normal weight (BMI = 18.50 - 24.99), overweight (BMI = 25.00 - 29.99), 1A obesity (BMI = 30.00 - 32.49), and 1B obesity (BMI ≥ 32.50). DS were assessed using the Patient Health Questionnaire (PHQ-9) instrument. A generalized linear model stratified by sex was constructed to calculate crude (cPRc) and adjusted (aPR) prevalence ratios. Results. A total of 26,463 records of people aged 18-60 years were assessed, yielding a 6.3% prevalence of DS (≥ 10 points). Females had a higher frequency of DS than males, which increased depending on their NS: normal weight 7.8%, overweight 8.2%, 1A obesity 9.0%, and 1B obesity 12.0%. Likewise, in the multivariate analysis, women with 1B obesity reported a higher frequency of DS (aPR = 1.30; 95% CI = [1.03, 1.63]). Discussion and conclusion. There is a strong association between nutritional status and depressive symptoms in Peruvian women, with obese women being more likely to have depressive symptoms.Acceso abierto

“Es cosa del dinero, siempre del dinero”. Exclusión social, agencia femenina y vínculos familiares en Las maravillas de Elena Medel(Universidad de Valladolid, 2022-11-01)The article proposes that Las maravillas (2020), by Elena Medel, shows the double social exclusion to which working women in Spain have been subjected, not only because of their status as women, but because they are poor. Likewise, it is desired to demonstrate that Medel's text puts on stage the ability of this social group to reflect on its precarious situation, organize itself and face said exclusion, all thanks to the emergence of female agency. Finally, the novel also affects the permeability of these women's family ties, which are redefined by the social class to which they belong.

Spatial distribution, determinants and trends of full vaccination coverage in children aged 12-59 months in Peru: A subanalysis of the Peruvian Demographic and Health Survey(BMJ Publishing Group, 2022-11-11)Objective To assess the spatial distribution, trends and determinants of crude full vaccination coverage (FVC) in children aged 12-59 months between 2010 and 2019 in Peru. Design, setting and analysis A cross-sectional study based on the secondary data analysis of the 2010 and 2019 Peruvian Demographic and Health Surveys (DHSs) was conducted. Logit based multivariate decomposition analysis was employed to identify factors contributing to differences in FVC between 2010 and 2019. The spatial distribution of FVC in 2019 was evaluated through spatial autocorrelation (Global Moran's I), ordinary kriging interpolation (Gaussian process regression) and Bernoulli-based purely spatial scan statistic. Outcome measure FVC, as crude coverage, was defined as having completely received BCG; three doses of diphtheria, pertussis, and tetanus, and polio vaccines; and measles vaccine by 12 months of age. Participants A total of 5 751 and 14 144 children aged 12-59 months from 2010 and 2019 DHSs, respectively, were included. Results FVC increased from 53.62% (95% CI 51.75% to 55.49%) in 2010 to 75.86% (95% CI 74.84% to 76.85%) in 2019. Most of the increase (70.39%) was attributable to differences in coefficients effects. Family size, visit of health workers in the last 12 months, age of the mother at first delivery, place of delivery and antenatal care follow-up were all significantly associated with the increase. The trend of FVC was non-linear and increased by 2.22% annually between 2010 and 2019. FVC distribution was heterogeneous at intradepartmental and interdepartmental level. Seven high-risk clusters of incomplete coverage were identified. Conclusions Although FVC has increased in Peru, it still remains below the recommended threshold. The increase of FVC was mainly attributed to the change in the effects of the characteristics of the population. There was high heterogeneity across Peruvian regions with the presence of high-risk clusters. Interventions must be redirected to reduce these geographical disparities.Acceso abierto

Relationship between resilience, optimism, and burnout in Pan-American athletes(Frontiers Media S.A., 2022-11-14)Aim: A series of knowledge has been developed on burnout syndrome in the sports context that has allowed to generate a solid theoretical structure that requires new contributions to delve into those aspects that have been less addressed, as is the case of optimism and resilience when it comes to linking them to the syndrome in top-performance athletes. For this purpose, the Burnout Inventory for Athletes (IBD-r), the Resilience Scale adapted to Spanish, and the Life Orientation Scale-Revised (LOT-R) for optimism were used. Methods: From this perspective, the study was approached with 121 Uruguayan athletes who participated in the last Pan-American Games, assuming practically all the subjects who have this level of sport (142) considering gender and type of sport. Results: The results indicate that 67% of the sample presents burnout symptoms for the emotional exhaustion dimension, and moderate resilience and optimism. Although there are no significant differences attributable to gender or type of sport, this contribution allows us to continue focusing on future work and further analysis. The type of sport presented statistically significant differences in relation to the personal competence dimension and the type of sport. Conclusion: Resilience and optimism obtained a clear influence on the occurrence of burnout, in a statistically negative sense, showing themselves as interesting prevention strategies for future lines of research, where it is essential to design interventions that teach emotional skills to manage adversity and prevent burnout.

A new approach to inertial damper design to control base displacement in isolated buildings(SAGE Publications Inc., 2022-12-01)A novel design procedure for tuned mass dampers in isolated structures is presented. The proposed optimization method is specifically developed to control base displacements or to solve the large isolator displacement problem in this type of structures under earthquakes. Therefore, it is based on a displacement transmissibility function, T, a particular case of the general transmissibility concept, which comes from Vibration Isolation. Three contributions are: 1) application of new seismic displacement narrowbandness, 2) simpler relative transmissibility function, and 3) compound design of isolation plus tuned mass damper. A standard isolated model is used to show that the base displacement can be controlled at levels in the proximity of the ground motion (T ≈ 1), which results in a positive comparison with previous isolation plus tuned mass damper solutions; this is one of the main conclusions and it is based on novelty 3 above; in fact, other solutions in the literature compare their attained displacements with respect to the structure without tuned mass damper. Comparison with isolated results is not, therefore, possible herein, but it is not desirable either; actually, what is possible is a positive and more demanding comparison, which is with respect to the very seismic ground displacement itself. The large isolator displacement problem can be solved or attenuated by properly designing a tuned mass damper subsystem jointly with the isolation one.Acceso abierto

Cross-cultural validity of the five items Mindful Attention Awareness Scale (MAAS-5) in Peru and Mexico during the COVID-19 pandemic(Springer Science and Business Media Deutschland GmbH, 2022-12-01)The Spanish version of the 5-item Mindful Attention Awareness Scale (MAAS-5) is a brief measure of the general tendency to be attentive and aware of experiences in the present moment during daily life. The MAAS-5 has been used in different countries; however, an assessment of its cross-cultural measurement invariance (MI) has not been conducted. Therefore, the study aimed to evaluate the cross-cultural measurement invariance of the MAAS-5 in university students from two countries: Peru and Mexico. A total of 1144 university students from Peru (N = 822) and Mexico (N = 322) responded online to the Spanish version of the 5-item Mindful Attention Awareness Scale (MAAS-5). A multigroup confirmatory factor analysis was performed. Measurement invariance tests the hypothesis that the model behind a set of scores is comparable between groups. The results showed that the unidimensional structure of the MAAS-5 is the same between Peruvian and Mexican university students. Therefore, it is suggested that university students from both countries conceptualize the mindfulness in a similar way. As a result, the MAAS-5 can be used to compare differences between countries. No significant differences were observed in the MAAS-5 score between Peruvian and Mexican university students. The present study contributes to a better understanding of the psychometric properties of the MAAS-5 by presenting MI results in two Latin American countries. Implications of the findings are discussed, which will facilitate a more solid and reliable use of the MAAS-5 in future cross-cultural studies.Acceso abierto

Meeting 24-h movement guidelines and markers of adiposity in adults from eight Latin America countries: the ELANS study(Nature Research, 2022-12-01)This study aimed to compare compliance with 24-h movement guidelines across countries and examine the associations with markers of adiposity in adults from eight Latin American countries. The sample consisted of 2338 adults aged 18–65 years. Moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB) data were objectively measured using accelerometers. Sleep duration was self-reported using a daily log. Body mass index and waist circumference were assessed as markers of adiposity. Meeting the 24-h movement guidelines was defined as ≥ 150 min/week of MVPA; ≤ 8 h/day of SB; and between 7 and 9 h/day of sleep. The number of guidelines being met was 0.90 (95% CI 0.86, 0.93) with higher value in men than women. We found differences between countries. Meeting two and three movement guidelines was associated with overweight/obesity (OR: 0.75, 95% CI 0.58, 0.97 and OR: 0.69, 95% CI 0.51, 0.85, respectively) and high waist circumference (OR: 0.74, 95% CI 0.56, 0.97 and OR: 0.77, 95% CI 0.62, 0.96). Meeting MVPA and SB recommendations were related to reduced adiposity markers but only in men. Future research is needed to gain insights into the directionality of the associations between 24-h movement guidelines compliance and markers of adiposity but also the mechanisms underlying explaining differences between men and women.Acceso abierto
