    Abstract We aimed to determine the variations in the prevalence of childhood anemia according to the ethnic group before and during the COVID-19 pandemic in Peru. Secondary analysis of the Demographic and Family Health Survey during 2016-2021. The outcome variable was anemia, and the exposure variable was maternal ethnicity. Also, we included sociodemographic and clinical confounding variables. We constructed generalized linear models of the Poisson family with a logarithmic link function. We evaluated 85,905 records; 30.34% had anemia, 50.83% were mestizo, 25.98% were Quechua, and 2% were Aymara. Compared with mestizos, Quechua children (PR: 1.11; 95% CI: 1.07-1.15; p < 0.001), Aymara (PR: 1.35; 95% CI: 1.27-1 .44; p < 0.001), natives of the Amazon (PR: 1.20; 95% CI: 1.12-1.28; p < 0.001) and those who belonged to other indigenous peoples (PR: 1.29; 95% CI: 1.05-1.57; p = 0.013) had a higher prevalence of childhood anemia. On the contrary, compared to mestizos, white children had a lower prevalence of anemia (PR: 0.93; 95% CI: 0.89-0.99; p = 0.019). During the COVID-19 pandemic, compared to mestizos, only Quechua (PR: 1.15; 95% CI: 1.08-1.23; p < 0.001) and Aymara (PR: 1.38; 95% CI: 1.23-1.55; p < 0.001) had a higher prevalence of childhood anemia. Except for Afro-descendants, children from 6 to 59 months of age who belong to an ethnic minority had a higher probability of having childhood anemia than mestizos. However, only Quechua and Aymara children had higher odds of anemia during the COVID-19 pandemic than mestizos.

    Abstract Optical inspection of 1191 silicon micro-strip sensors was performed using a custom made optical inspection setup, employing a machine-learning based approach for the defect analysis and subsequent quality assurance. Furthermore, metrological control of the sensor's surface was performed. In this manuscript, we present the analysis of various sensor surface defects. Among these are implant breaks, p-stop breaks, aluminium strip opens, aluminium strip shorts, surface scratches, double metallization layer defects, passivation layer defects, bias resistor defects as well as dust particle identification. The defect detection was done using the application of Convolutional Deep Neural Networks (CDNNs). From this, defective strips and defect clusters were identified, as well as a 2D map of the defects using their geometrical positions on the sensor was performed. Based on the total number of defects found on the sensor's surface, a method for the estimation of sensor's overall quality grade and quality score was proposed.

    Abstract Objective: To compare the mortality rates from COVID-19 among indigenous populations of the Amazon and Andean regions of Peru during the years 2020, 2021 and 2022.
    Methods: Secondary analysis of 33,567 data from the COVID-19 Notification System of the National Epidemiology Center, Prevention and Control of Diseases (CDC-Peru), from the years 2020-2022. The variables were age, sex, belonging to the Andean or Amazonian ethnic group, number and type of symptoms and risk conditions, abnormal findings in chest X-rays, year of data collection for hospitalization and death from COVID-19. Poisson family generalized linear regression models with logarithmic linkage and robust variance were used to establish differences in mortality between ethnic groups. Crude and adjusted risk ratio (RR) with 95 % confidence intervals (CI) were calculated.
    Results: 33,567 participants with an average age of 33.6 years were included, 44.4 % were men and 70.2 % belonged to the Amazonian ethnic group. Most of those affected by COVID-19 presented 2 symptoms (38.8 %), 4.8 % presented some risk condition, 1451 (4.3 %) were hospitalized, and 433 (1.3 %) died. The adjusted analysis showed that the Andean group, compared to the Amazonian, tended to have a higher probability of death, and this association was statistically significant, RR =7.6, 95 % CI (5.5-10.5).
    Conclusions: Patients from Andean indigenous communities had an almost 8 times higher risk of death from COVID-19.

    Abstract Background: Pandemic fatigue generates low motivation or the ability to comply with protective behaviors to mitigate the spread of COVID-19.
    Aims: This study aimed to analyze the symptoms of pandemic fatigue through network analysis in individuals from five South American countries.
    Method: A total of 1,444 individuals from Argentina, Bolivia, Paraguay, Peru, and Uruguay participated and were evaluated using the Pandemic Fatigue Scale. The networks were estimated using the ggmModSelect estimation method and a polychoric correlation matrix was used. Stability assessment of the five networks was performed using the nonparametric resampling method based on the case bootstrap type. For the estimation of network centrality, a metric based on node strength was used, whereas network comparison was performed using a permutation-based approach.
    Results: The results showed that the relationships between pandemic fatigue symptoms were strongest in the demotivation dimension. Variability in the centrality of pandemic fatigue symptoms was observed among participating countries. Finally, symptom networks were invariant and almost identical across participating countries.
    Conclusions: This study is the first to provide information on how pandemic fatigue symptoms were related during the COVID-19 pandemic.

    Abstract We present the recent development of a lightweight detector capable of accurate spatial, timing, and amplitude resolution of charged particles. The technology is based on double-sided double-metal p+\,--\,n\,--\,n+ micro-strip silicon sensors, ultra-light long aluminum-polyimide micro-cables for the analogue signal transfer, and a custom-developed SMX read-out ASIC capable of measurement of the time ($\Delta t \lesssim 5 \,\mathrm{ns}$) and amplitude. Dense detector integration enables a material budget $>0.3\,\% X_0$. A sophisticated powering and grounding scheme keeps the noise under control. In addition to its primary application in Silicon Tracking System of the future CBM experiment in Darmstadt, our detector will be utilized in other research applications.

    Abstract The 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.

    Abstract The aim of this study was to determine the relationship between COVID-19 severity and androgenic alopecia in patients hospitalized in the Surgery Service of Honorio Delgado Espinoza Hospital in Arequipa, Peru. A cross-sectional study was performed in male patients with a diagnosis of COVID-19. Alopecia, clinical characteristics, treatment, and evolution were collected. In all, 98 patients were included; median age was 55 years old (range 18-89), 32.7% with comorbidities, and 45.9% with androgenic alopecia. The severity of COVID-19 infection was moderate to severe in 13.2% of patients without alopecia, and in 88.9% of patients with alopecia (p>0.001). In the logistic regression model analysis, patients with alopecia had a higher risk of presenting moderate to severe symptoms due to SARS-CoV-2 infection (OR: 80.2; 95% CI 16.2-397.7). In conclusion, the severity of infection was statistically significant in patients over 60 years old and those with alopecia.

    Abstract Background: The COVID-19 pandemic is an unprecedented challenge to health systems that has revealed shortcomings and increased unmet demands. Such situations might exacerbate workplace violence (WPV) against physicians, as has been reported in several parts of the world.
    Methods: To identify the frequency and characteristics of WPV suffered by physicians attending COVID-19 patients in Peru, a descriptive, cross-sectional study was conducted with an online survey of 200 physicians.
    Results: Of the survey respondents, 84.5% had suffered some type of WPV; 97.6% of these suffered nonphysical violence. Suffering more than one incident of violence was reported by 75.7% of respondents. The primary aggressor was a patient's family member or caregiver. Violence occurred most frequently in critical areas inside the health service facility, such as COVID-19 triage, tents, and hospital units, although it also occurred during teleconsultations. Multiple shortcomings of the health services were perceived as the main trigger of violence. Being a female physician (odds ratio [OR] = 2.48, 95% confidence interval [CI] = 1.06-5.83) and working in a COVID-19 ICU (OR = 5.84, 95% CI = 1.60-21.28) were the main factors associated with WPV.
    Conclusion: Violence against physicians attending COVID-19 patients in Peru is common. The perceived factors that contribute most to violence are linked to deficiencies in health services.

    Abstract The present study evaluated the predictive capacity of fear of Monkeypox (MPX) on the intention to be vaccinated against MPX and the influence of conspiracy beliefs as a mediating variable in this relationship in 516 Peruvian sample with an average age of 27.10 years participated. Monkeypox Fear Scale, MPX Conspiracy Beliefs Scale and a single item of intention to be vaccinated against MPX were used. Statistical analyses have included estimation of descriptive statistics for all variables in the model tested and Structural Equation Modeling to predict intention to be vaccinated against monkeypox. It has been found that fear has a positive impact on conspiracy beliefs about MPX and intention to be vaccinated against MPX. Finally, conspiracy beliefs are negatively related to intention to be vaccinated. As for indirect effects, both are statistically significant. The model explains 11.4% of the variance in beliefs and 19.1% in intention to be vaccinated. It is concluded that fear of MPX played an important role, both directly and indirectly, in the intention to be vaccinated against MPX, having conspiratorial beliefs about MPX as a mediating variable. The results have important implications for public health practices aimed at combating doubts about MPX vaccination.

    Abstract Background: Fear is one of the basic emotions generated during periods of infectious diseases. Therefore, the aim of this study was to develop and validate a scale that assesses monkeypox fear, the Monkeypox Fear Scale (MFS).
    Methods: A total of 451 Peruvians participated (61% women and 39% men), with a mean age of 28.31 years (SD = 9.72). based on procedures from classical test theory (CTT) and item response theory (IRT). Classical Test Theory (CTT) and Item Response Theory (IRT) procedures were used.
    Results: The results showed that MFS has a two-factor structure related to emotional and physiological fear factors (χ2 = 41.87; df = 12; p < .001; CFI = .99; TLI = .99; RMSEA = .074 [IC90% .051-.100]). In addition, the physiological and emotional factors showed good reliability. Measurement invariance analysis showed that the factor structure of the MFS is strictly invariant between male and female groups. Finally, the discrimination and difficulty parameters of the items show adequacy. In addition, the scale seems to be more accurate in measuring high levels of fear of monkeypox.
    Conclusion: The MFS has adequate psychometric evidence to assess fear of monkeypox in the Peruvian population. These findings may guide future studies related to the consequences of monkeypox on mental health.
