Clinical-epidemiologic variation in patients treated in the first and second wave of COVID-19 in Lambayeque, Peru: A cluster analysis
(Elsevier Ltd, 2022-07-18) Valladares-Garrido, Mario J.; Failoc-Rojas, Virgilio E.; Soto-Becerra, Percy; Zeña-Ñañez, Sandra; Torres-Roman, J. Smith; Fernández-Mogollón, Jorge L.; Colchado-Palacios, Irina G.; Apolaya-Segura, Carlos E.; Dávila-Gonzales, Jhoni A.; Arce-Villalobos, Laura R.; Neciosup-Puican, Roxana del Pilar; Calvay-Requejo, Alexander G.; Maguiña, Jorge L.; Apolaya-Segura, Moisés; Díaz-Vélez, Cristian
“Objectives: To identify differences in the clinical and epidemiologic characteristics of patients during the first and second waves of the COVID-19 pandemic at the EsSalud Lambayeque health care network, Peru. Methods: An analytical cross-sectional study of 53,912 patients enrolled during the first and second waves of COVID-19 was conducted. Cluster analysis based on clustering large applications (CLARA) was applied to clinical-epidemiologic data presented at the time of care. The two pandemic waves were compared using clinical-epidemiologic data from epidemiologic surveillance. Results: Cluster analysis identified four COVID-19 groups with a characteristic pattern. Cluster 1 included the largest number of participants in both waves, and the participants were predominantly female. Cluster 2 included patients with gastrointestinal, respiratory, and systemic symptoms. Cluster 3 was the “severe” cluster, characterized by older adults and patients with dyspnea or comorbidities (cardiovascular, diabetes, obesity). Cluster 4 included asymptomatic, pregnant, and less severe patients. We found differences in all clinical-epidemiologic characteristics according to the cluster to which they belonged. Conclusion: Using cluster analysis, we identified characteristic patterns in each group. Respiratory, gastrointestinal, dyspnea, anosmia, and ageusia symptoms were higher in the second COVID-19 wave than the first COVID-19 wave“

“Fire burns matter: A case-control study of severe accidental burns in pediatric patients“
(Modestum LTD, 2022-10-15) Rojas-Contreras, Christian; De la Cruz-Ku, Gabriel; Eyzaguirre-Sandoval, Miguel Eduardo; Chambergo-Michilot, Diego; Torres-Roman, J. Smith
“Objective: We aimed to identify factors associated with severe accidental burns in patients ≤12 years old. Materials and methods: We conducted a matched case-control study, in which we retrospectively reviewed the medical records of children treated in a single institution from 2014-2016. We classified the cases (patients with severe burns) and controls (patients with non-severe burns) according to the criteria of the American Burn Association. We used multivariate conditional logistic regression analysis to identify the relationship between the etiology of burns and their severity. Results: We reviewed 180 cases and 90 controls. The most common etiology of burns was boiling water in both cases (65.6%) and controls (83.3%). Most burns occurred inside the home (84.1%) and in the afternoon (37.4%). Multivariate analysis identified that severe burns were mainly due to exposure to fire (odds ratio [OR]: 3.22, 95% confidence interval [CI]: 1.53-6.81). Similarly, these patients were more likely to live in a rural area (OR: 2.96, 95% CI: 1.17-6.19). Conclusions: In pediatric patients ≤12 years of age severe accidental burns are more likely to be caused by fire compared to boiling water. Public health interventions should focus on populations located in rural areas.“

“HIV therapy adherence and outcomes in Peruvian military personnel over a 30-year period“
(Modestum LTD, 2022-11-27) De la Cruz Ku, Gabriel; Rojas Contreras, Christian; Chambergo-Michilot, Diego; Torres-Roman, J. Smith; Príncipe-Meneses, Fortunato S.; Rioja Torres, Flavia; Campana Zamudio, Fátima; Pérez Pachas, Gonzalo; Huamán Modesto, Alfredo; Chavez, Victoria
“Objectives: We aimed to describe the sociodemographic, clinical, and therapeutic characteristics of Peruvian military personnel diagnosed with HIV. Furthermore, we determined the frequency of highly active antiretroviral therapy (HAART) adherence, the complications and mortality. Methods: We retrospectively reviewed the medical records of patients diagnosed with HIV, confirmed by Western blot at a single institution from 1989-2020. Descriptive analyses were performed for all the variables using mean and standard deviation (SD) in the case of quantitative variables, and frequency and percentage for qualitative variables. Results:Ofthe 161 patients included, 95.7% were males and the mean age was 39.59 years (SD= 16.45 years). Most had college or higher education (67.7%) and were on active duty at diagnosis (77%). 35.4% had AIDS at diagnosis; 28.6% opportunistic infections; and 8.1% tuberculosis. The median follow-up was five years. 94.4% of the patients received HAART as the principal treatment; of these, 88.8% was adherent to treatment, and death was reported in 6.8%. There were no factors associated with adherence. Conclusions: Although the sociodemographic characteristics of Peruvian military personnel are similar to those of other countries, our findings suggest that Peruvian military personnel present higher adherence to HAART compared to previous studies in other military populations from South American countries. Further studies are recommended to assess specific factors attributed to these successful outcomes in the military personnelthat can be applied in other hospitals“

Mortality trends and geographic distribution of kidney cancer in Peru: a secondary analysis
(BioMed Central Ltd, 2023) Torres-Roman, J. Smith; De la Cruz-Ku, Gabriel; Juárez-Leon, Valeria; Calderón-Solano, Delahnie; Bazalar-Palacios, Janina; La Vecchia, Carlo; Pinheiro, Paulo S.
Background The incidence of kidney cancer has been increasing worldwide, with variable patterns in mortality due to improved diagnostic techniques and increased survival. The mortality rates, geographical distribution and trends of kidney cancer in South America remain poorly explored. This study aims to illustrate mortality by kidney cancer in Peru. Methods A secondary data analysis of the Deceased Registry of the Peruvian Ministry of Health database, from 2008 to 2019 was conducted. Data for kidney cancer deaths were collected from health facilities distributed throughout the country. We estimated age-standardized mortality rates (ASMR) per 100,000 persons and provided an overview of trends from 2008 to 2019. A cluster map shows the relationships among 3 regions. Results A total of 4221 deaths by kidney cancer were reported in Peru between 2008 and 2019. ASMR for Peruvian men ranged from 1.15 to 2008 to 1.87 in 2019, and from 0.68 to 2008 to 0.82 in 2019 in women. The mortality rates by kidney cancer rose in most regions, although they were not significant. Callao and Lambayeque provinces reported the highest mortality rates. The rainforest provinces had a positive spatial autocorrelation and significant clustering (p

The mortality rates by kidney cancer rose in most regions, although they were not significant. Callao and Lambayeque provinces reported the highest mortality rates. The rainforest provinces had a positive spatial autocorrelation and significant clustering (p<0.05) with the lowest rates in Loreto and Ucayali. Conclusion Mortality by kidney cancer has increased in Peru, being a trend that disproportionally affects more men than women. While the coast, especially Callao and Lambayeque, present the highest kidney cancer mortality rates, the rainforest has the lowest rates, especially among women. Lack of diagnosis and reporting systems may confound these results.“
