Testicular cancer mortality in Latin America and the Caribbean: trend analysis from 1997 to 2019.

BACKGROUND: In the last decades, an increasing incidence of testicular cancer has been observed in several countries worldwide. Although mortality rates have been variable in many countries, little information is available from Latin America and the Caribbean (LAC). Therefore, we examined mortality trends of testicular cancer in the last two decades. METHODS: Age-standardized mortality rates (ASMR) of testicular cancer per 100,000 men-years were estimated using the World Health Organization mortality database from 1997 to 2019. We examined the mortality trends and computed annual percent change (APC) for all ages and the following age groups, 15-29, 30-44, 15-44, and ≥ 45 years. RESULTS: Ten countries had mortality rates greater than 0.43 per 100,000 men, with the highest rates for Chile, Mexico, and Argentina. Significant increases in mortality rates were observed in Argentina, Brazil Colombia, and Mexico in all ages, and < 45 years, while Colombia, Ecuador, Mexico, and Peru reported significant downward trends in males aged ≥ 45 years. Only Chile showed significant decreases for all ages and age groups studied. CONCLUSION: Mortality by testicular cancer increased among LAC countries in males of all ages and across age groups. A reduction in mortality rates was observed only in Chilean males of all ages and in men ≥ 45 years in several countries. Strengthening of early detection among symptomatic males may decrease the mortality by this neoplasm.

The impact of body mass index on oncoplastic breast surgery: A multicenter analysis.

BACKGROUND: Obesity has nearly tripled in the last 50 years. During the last decades, oncoplastic breast surgery has become an important choice in the surgical treatment of breast cancer. An association exists between higher body mass index (BMI) and wound complications for major operations, but there is scarce literature on oncoplastic surgery. Hence, our aim was to compare the complication rates among patients who underwent oncoplastic surgery, stratified by BMI. METHODS: Patient data were analyzed from the National Surgical Quality Improvement Program database (NSQIP) for oncoplastic breast procedures (2005-2020). Patients were stratified according to World Health Organization obesity classifications. Multivariate logistic regression was performed to assess risk factors for complications (overall, operative, and wound-related). RESULTS: From a total of 6887 patients who underwent oncoplastic surgery, 4229 patients were nonobese, 1380 had Class 1 obesity (BMI: 30 to <35 kg/m2 ), 737 Class 2 obesity (BMI: 35 to <40 kg/m2 ), and 541 Class 3 obesity (BMI: ≥ 40 kg/m2 ). Greater operative time was found according to higher BMI (p < 0.001). Multivariate analysis adjusted for baseline characteristics showed that patients with obesity Class 2 (odds ratio [OR] = 1.51, 95% confidence interval [CI]: 1.03-2.23, p = 0.037) and 3 (OR = 1.87, 95% CI 1.24-2.83, p = 0.003) had increased risk of overall and wound complications compared with Nonobese patients. Comparing obese with nonobese patients, there were no differences in rates of deep SSI, organ/space SSI, pneumonia, reintubation, pulmonary embolism, deep vein thrombosis, urinary tract infection, stroke, bleeding, postoperative sepsis, length of stay, and readmission. CONCLUSIONS: Oncoplastic surgery is a safe procedure for most patients. However, caution should be exercised when performing oncoplastic surgery for patients with Class 2 or 3 obesity (BMI ≥ 35 kg/m2 ), given there was a higher rate of overall and wound-specific complications, compared with patients who were not obese or had Class 1 obesity.

Mortality trends and geographic distribution of kidney cancer in Peru: a secondary analysis.

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 < 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.

Disparities in breast cancer mortality among Latin American women: trends and predictions for 2030.

BACKGROUND: Breast cancer is among the leading cause of cancer-related mortality among Latin American and Caribbean (LAC) women, but a comprehensive and updated analysis of mortality trends is lacking. The objective of this study was to determine the breast cancer mortality rates between 1997 and 2017 for LAC countries and predict mortality until 2030. METHODS: We retrieved breast cancer deaths across 17 LAC countries from the World Health Organization mortality database. Age-standardized mortality rates per 100,000 women-years were estimated. Mortality trends were evaluated with Joinpoint regression analyses by country and age group (all ages, < 50 years, and ≥ 50 years). By 2030, we predict number of deaths, mortality rates, changes in population structure and size, and the risk of death from breast cancer. RESULTS: Argentina, Uruguay, and Venezuela reported the highest mortality rates throughout the study period. Guatemala, El Salvador, and Nicaragua reported the largest increases (from 2.4 to 2.8% annually), whereas Argentina, Chile, and Uruguay reported downward trends (from - 1.0 to - 1.6% annually). In women < 50y, six countries presented downward trends and five countries showed increasing trends. In women ≥ 50y, three countries had decreased trends and ten showed increased trends. In 2030, increases in mortality are expected in the LAC region, mainly in Guatemala (+ 63.0%), Nicaragua (+ 47.3), El Salvador (+ 46.2%), Ecuador (+ 38.5%) and Venezuela (+ 29.9%). CONCLUSION: Our findings suggest considerable differences in breast cancer mortality across LAC countries by age group. To achieve the 2030 sustainable developmental goals, LAC countries should implement public health strategies to reduce mortality by breast cancer.

Regional disparities of prostate cancer mortality in Ecuador: an examination of trends and correlates from 2004 to 2019.

BACKGROUND: Prostate cancer is the leading cause of cancer death in Ecuadorian men. However, there is a lack of information regarding the evolution of prostate cancer mortality rates in Ecuador and its regions in the last few decades. OBJECTIVE: The aim of this study was to report prostate cancer mortality rates in Ecuador and its geographical areas and observe the evolution of these rates between 2004 and 2019. METHODS: An observational ecological study was conducted, analysing data for prostate cancer deaths from 2004 to 2019 in Ecuador. Age standardized mortality rates (ASMR) were calculated per 100,000 men using the world standard population with the direct method proposed by SEGI. Joinpoint regression analysis was performed to examine mortality trends. We used a Cluster Map to explore relationships among regions between 2015 and 2019. RESULTS: Ecuador reported 13,419 deaths by prostate cancer between 2004 and 2019, with the Coastal region accounting for 49.8% of the total deaths. The mean age at death was 79 years (± 10 years), 91.7% were elderly (more than 65 years old) and had primary education (53%). Deaths by prostate cancer were more frequently reported among mestizos (81.4%). There were no significant variations in these percentages in Ecuador and its regions during the study period. Carchi province had the highest mortality rate in 2005 and 2019 (> 13 deaths per 100,000). Heterogeneity in the evolution of mortality rates was reported among the provinces of Ecuador. Azuay decreased in the first few years, and then increased from 2010 to 2019, whereas Guayas and Pichincha decreased throughout the whole period. CONCLUSION: Although prostate cancer mortality rates in Ecuador have remained stable over the past few decades, there are significant disparities among the different regions. These findings suggest the need for the development of national and provincial registration measures, integrated healthcare actions, and targeted interventions to reduce the burden of prostate cancer in the Ecuadorian population.

Efficacy and Safety of Apixaban versus Dalteparin as a Treatment for Cancer-Associated Venous Thromboembolism: A Systematic Review and Meta-Analysis.

Background and Objectives: Venous thromboembolism (VTE) is common in cancer patients. Anticoagulant therapy with low-molecular-weight heparins (LMWHs) and direct oral anticoagulants (DOACs), such as dalteparin and apixaban, have demonstrated efficacy and safety. However, more comparative research of these drugs is still needed. This study aimed to synthesize evidence on the efficacy of apixaban compared to dalteparin in reducing recurrent VTE, major bleeding, and clinically relevant non-major bleeding associated with cancer. Materials and Methods: We systematically searched the PubMed, Scopus, Web of Science, Embase, Cochrane Library, and ClinicalTrials databases up to 5 January 2023, for randomized controlled trials comparing apixaban versus dalteparin as treatment for cancer-associated VTE. Five studies were included. Effects according to meta-analyses were reported as relative risks (RRs) and their 95% confidence intervals (CIs). Results: It was found that 33 of 734 (4.5%) patients treated with apixaban and 56 of 767 (7.3%) with dalteparin had recurrent VTE as the efficacy outcome (RR 0.49, 95% CI 0.15-1.58, I2 38%). Major bleeding occurred in 25 of 734 patients treated with apixaban (3.4%) and 27 of 767 with dalteparin (3.5%) (RR 1.29, 95% CI 0.31-5.27, I2 59%). Likewise, clinically relevant non-major bleeding occurred in 64 of 734 patients treated with apixaban (8.7%) and 46 of 767 (5.9%) with dalteparin (RR 1.52, 95% CI 1.05-2.19, I2 0%). Conclusions: Apixaban showed a lower risk of recurrent VTE than dalteparin in patients with cancer-associated VTE, albeit with no statistical difference. Statistical significance was observed for no major clinically relevant bleeding but not for major bleeding.

Cervical cancer mortality among young women in Latin America and the Caribbean: trend analysis from 1997 to 2030.

BACKGROUND: Cervical cancer continues to show a high burden among young women worldwide, particularly in low- and middle-income countries. Limited data is available describing cervical cancer mortality among young women in Latin America and the Caribbean (LAC). The purpose of this study was to examine the mortality trends of cervical cancer among young women in LAC and predict mortality rates to 2030. METHODS: Deaths from cervical cancer were obtained from the World Health Organization mortality database. Age-standardized mortality rates per 100,000 women-years were estimated in women aged 20-44 years using the world standard population for 16 countries (and territories) in LAC from 1997 to 2017. We estimated the average mortality rates for the last 4 years (2014-2017). Joinpoint regression models were used to identify significant changes in mortality trends. Nordpred method was used for the prediction of the mortality rates to 2030. RESULTS: Between 2014 and 2017, Paraguay and Venezuela had the highest mortality rates of cervical cancer, whereas Puerto Rico had the lowest rates. Overall, most of the LAC countries showed downward trends of cervical cancer mortality over the entire period. Significant decreases were observed in Chile (Average annual percent change [AAPC]: - 2.4%), Colombia (AAPC: - 2.0%), Cuba (AAPC: - 3.6%), El Salvador (AAPC: - 3.1%), Mexico (AAPC: - 3.9%), Nicaragua (AAPC: - 1.7%), Panama (AAPC: - 1.7%), and Peru (AAPC: - 2.2%). In contrast, Brazil (AAPC: + 0.8%) and Paraguay (AAPC: + 3.7%) showed significant upward trends. By 2030, mortality rates are not predicted to further decrease in some LAC countries, including Argentina, Paraguay, and Venezuela. CONCLUSIONS: Mortality trends of cervical cancer among young women have large variability in LAC countries. Cervical cancer screening programs have a high priority for the region. Primary and secondary prevention in the community are necessary to accelerate a reduction of cervical cancer mortality by 2030.

Cervical cancer mortality in Peru: regional trend analysis from 2008-2017.

BACKGROUND: Cervical cancer is the third leading cause of cancer-related death among Latin American women. Peru has the sixth highest mortality rate for cervical cancer in the region with regional variations. We aimed to determine overall and regional cervical cancer mortality rates and trends in Peru between 2008 and 2017. METHODS: We performed an ecological study on the number of deaths by cervical cancer in Peru. Deaths were extracted from the Peruvian Ministry of Health mortality database. Age-standardized mortality rates (ASMR) were estimated per 100,000 women-years using the world standard Segi population. We computed mortality trends using the Joinpoint regression program, estimating the annual percent change (APC). For spatial analysis, GeoDA software was used. RESULTS: Peru showed downward trends in the last decade (from 11.62 in 2008 to 9.69 in 2017 (APC = - 2.2, 95% CI: - 4.3, - 0.1, p < 0.05). According to regional-specific analysis, the highest ASMR was in the rainforest region, although this declined from 34.16 in 2008 to 17.98 in 2017 (APC = - 4.3, 95% CI: - 7.2, - 1.3, p < 0.01). Concerning spatial analysis and clustering, the mortality rates from 2008 to 2017 showed a positive spatial autocorrelation and significant clustering (Moran's I: 0.35, p < 0.001) predominantly in the neighboring North-East departments (Loreto, Ucayali, and San Martin). CONCLUSIONS: Although mortality trends in the entire population are decreasing, mortality rates remain very high, mainly in the rainforest region. Our results encourage a need for further development and improvement of the current health care delivery system in Peru.

Breast cancer mortality trends in Peruvian women.

BACKGROUND: Breast cancer (BC) is the most common malignancy in Latin American women, but with a wide variability with respect to their mortality. This study aims to estimate the mortality rates from BC in Peruvian women and to assess mortality trends over 15 years. METHODS: We calculated BC age-standardized mortality rate (ASMR) per 100,000 women-years using the world standard SEGI population. We estimated joinpoint regression models for BC in Peru and its geographical areas. The spatial analysis was performed using the Moran's I statistic. RESULTS: In a 15-year period, Peru had a mortality rate of 9.97 per 100,000 women-years. The coastal region had the highest mortality rate (12.15 per 100,000 women-years), followed by the highlands region (4.71 per 100,000 women-years). In 2003, the highest ASMR for BC were in the provinces of Lima, Arequipa, and La Libertad (above 8.0 per 100,000 women-years), whereas in 2017, the highest ASMR were in Tumbes, Callao, and Moquegua (above 13.0 per women-years). The mortality trend for BC has been declining in the coastal region since 2005 (APC = - 1.35, p < 0.05), whereas the highlands region experienced an upward trend throughout the study period (APC = 4.26, p < 0.05). The rainforest region had a stable trend. Spatial analysis showed a Local Indicator of Spatial Association of 0.26 (p < 0.05). CONCLUSION: We found regional differences in the mortality trends over 15 years. Although the coastal region experienced a downward trend, the highlands had an upward mortality trend in the entire study period. It is necessary to implement tailored public health interventions to reduce BC mortality in Peru.

Leukemia mortality in children from Latin America: trends and predictions to 2030.

BACKGROUND: Reports suggest that Latin American and Caribbean (LAC) countries have not reduced leukemia mortality compared to high-income countries. However, updated trends remain largely unknown in the region. Given that leukemia is the leading cause of cancer-related death in LAC children, we evaluated mortality trends in children (0-14y) from 15 LAC countries for the period 2000-2017 and predicted mortality to 2030. METHODS: We retrieved cancer mortality data using the World Health Organization Mortality Database. Mortality rates (standardized to the world standard SEGI population) were analyzed for 15 LAC countries. We evaluated the average mortality rates for the last 5 years (2013-2017). Joinpoint regression analysis was used to evaluate leukemia mortality trends and provide an estimated annual percent change (EAPC). Nordpred was utilized for the calculation of predictions until 2030. RESULTS: Between 2013 and 2017, the highest mortality rates were reported in Venezuela, Ecuador, Nicaragua, Mexico, and Peru. Upward mortality trends were reported in Nicaragua (EAPC by 2.9% in boys, and EAPC by 2.0% in girls), and Peru (EAPC by 1.4% in both sexes). Puerto Rico experienced large declines in mortality among both boys (EAPC by - 9.7%), and girls (EAPC by - 6.0%). Leukemia mortality will increase in Argentina, Ecuador, Guatemala, Panama, Peru, and Uruguay by 2030. CONCLUSION: Leukemia mortality is predicted to increase in some LAC countries by 2030. Interventions to prevent this outcome should be tailor to reduce the socioeconomic inequalities and ensure universal healthcare coverage.

The effect of early-stage public health policies in the transmission of COVID-19 for South American countries.

OBJECTIVES: The analysis of transmission dynamics is crucial to determine whether mitigation or suppression measures reduce the spread of coronavirus disease 2019 (COVID-19). This study sought to estimate the basic (R0 ) and time-varying (Rt ) reproduction number of COVID-19 and contrast the public health measures for ten South American countries. METHODS: Data was obtained from the European Centre for Disease Prevention and Control. Country-specific R0 values during the first two weeks of the outbreak and Rt values after 90 days were estimated. RESULTS: Countries used a combination of isolation, physical distancing, quarantine, and community-wide containment measures to staunch the spread of COVID-19 at different points in time. R0 ranged from 1.52 (95% confidence interval: 1.13-1.99) in Venezuela to 3.83 (3.04-4.75) in Chile, whereas Rt after 90 days ranged from 0.71 (95% credible interval: 0.39-1.05) in Uruguay to 1.20 (1.19-1.20) in Brazil. Different R0 and Rt values may be related to the testing capacity of each country. CONCLUSION: R0 in the early phase of the outbreak varied across the South American countries. The public health measures adopted in the initial period of the pandemic appear to have reduced Rt over time in each country, albeit to different levels.

OBJETIVOS: Estimar el número de reproducción básico (R0 ) y el número de reproducción efectivo (Rt ) de la COVID-19 y contrastarlos con las medidas de salud pública implementadas en diez países de América del Sur. MÉTODOS: Los datos se obtuvieron del Centro Europeo para la Prevención y el Control de las Enfermedades. Se estimó el R0 de cada país durante las dos primeras semanas del brote y el Rt después de 90 días. RESULTADOS: Los países utilizaron una combinación de aislamiento, distanciamiento físico, cuarentena y medidas de contención en toda la comunidad para detener la propagación de la COVID-19 en diferentes momentos. El R0 osciló entre 1,52 (IC95%: 1,13-1,99) en Venezuela y 3,83 (IC95%: 3,04-4,75) en Chile, mientras que el Rt después de 90 días varió entre 0,71 (intervalo de credibilidad 95%: 0,39-1,05) en Uruguay y 1,20 (intervalo de credibilidad 95%: 1,19-1,20) en Brasil. Los diferentes valores de R0 y Rt pueden estar relacionados con la capacidad de llevar a cabo pruebas de detección viral de cada país. CONCLUSIÓN: Los valores del R0 en la fase inicial del brote variaron entre los países sudamericanos. Las medidas de salud pública adoptadas en el período inicial de la pandemia parecen haber reducido el Rt con el tiempo en cada país, aunque en niveles diferentes.

Geographic differences in overweight and obesity prevalence in Peruvian children, 2010-2015.

BACKGROUND: Childhood obesity is emerging as a major public health problem worldwide. To date, most studies of obesity and overweight in Peru are focused on adults, with few of them involving children, a population at a critical stage of development. The trend in overweight and obesity prevalence in Peruvian children under the age of five has not yet been determined. Thus, the objective of the present study is to evaluate the prevalence rates of overweight and obesity between 2010 and 2015 in children under the age of five, stratified by geographical areas in Peru. METHODS: Data were obtained from the Nutritional Status Information System of Peru. The total number of children evaluated was 14,155,914. For the Geographic Information Systems (GIS), the program Geo Da 1.8® was used to ascertain the spatial distribution of prevalence rates and was mapped for children under five. To assess the degree of spatial dependence, exploratory spatial data analysis was performed using the Moran's I statistic and was assessed with the Local Indicators of Spatial Association (LISA) analysis to identify geographic concentrations of high and low of obesity and overweight levels. RESULTS: Between 2010 and 2015, the national prevalence of childhood overweight and obesity ranged from 6.2%- 6.8% and 1.5%-2.7%, respectively. The highest prevalence of childhood overweight and obesity was found in 2014 and 2013, respectively. During these years, we observed that obesity decreased, but overweight remained stable. The highest prevalence of overweight and obesity was found in the departments located on the coast. Significant positive spatial autocorrelation was found for both overweight and obesity. The departments with the highest prevalence of overweight and obesity were concentrated in Lima, Callao, Ica, Moquegua and Tacna. The lowest were found in Loreto, Cusco and San Martin. CONCLUSION: The decrease in obesity and the stabilisation of overweight are positive results for the Peruvian childhood. However, in comparison with other Latin American countries, Peru still lags in obesity prevention.

Survival according to the site of metastasis in triple-negative breast cancer patients: The Peruvian experience.

BACKGROUND: Evidence regarding differences in survival associated with the site of metastasis in triple-negative breast cancer (TNBC) remains limited. Our aim was to analyze the overall survival (OS), distant relapse free survival (DRFS), and survival since the diagnosis of the relapse (MS), according to the side of metastasis. METHODS: This was a retrospective study of TNBC patients with distant metastases at the Instituto Nacional de Enfermedades Neoplasicas (Lima, Peru) from 2000 to 2014. Prognostic factors were determined by multivariate Cox regression analysis. RESULTS: In total, 309 patients were included. Regarding the type of metastasis, visceral metastasis accounted for 41% and the lung was the most frequent first site of metastasis (33.3%). With a median follow-up of 10.2 years, the 5-year DRFS and OS were 10% and 26%, respectively. N staging (N2-N3 vs. N0, HR = 1.49, 95%CI: 1.04-2.14), metastasis in visceral sites (vs. bone; HR = 1.55, 95%CI: 0.94-2.56), the central nervous system (vs. bone; HR = 1.88, 95% CI: 1.10-3.22), and multiple sites (vs. bone; HR = 2.55, 95%CI:1.53-4.25) were prognostic factors of OS whereas multiple metastasis (HR = 2.30, 95% CI: 1.42-3.72) was a predictor of MS. In terms of DRFS, there were no differences according to metastasis type or solid organ. CONCLUSION: TNBC patients with multiple metastasis and CNS metastasis have an increased risk of death compared to those with bone metastasis in terms of OS and MS.

Clinical Features and Outcomes of Triple-Negative Breast Cancer Among Latin American Adolescents and Young Adults Compared to Middle-Aged and Elder Females: A Cohort Analysis Over 15 Years.

Purpose: Outcomes of females with triple-negative breast cancer (TNBC) are rarely explored in adolescents and young adults (AYAs). We compared clinical and survival outcomes of Latin American AYAs (≤39 years) with middle-aged (40-59 years) and older (≥60 years) females with TNBC by cancer stage. Methods: We performed a single-center retrospective cohort study among treated females with cancer stages I-III diagnosed from 2000 to 2014 in Peru. We evaluated overall survival (OS) and event-free survival (EFS). Time-to-event methods were used for analyses. Results: Of 1582 females with TNBC, 350 (22%) were AYAs, 887 (56%) were middle-aged, and 345 (22%) were older women. Tumor size >5 cm, histological grade III, and brain metastasis were more common features in AYAs. AYAs were treated more frequently with neoadjuvant chemotherapy. With a median follow-up of 102 months, the 5-year OS/EFS for AYAs was 55%/53%, similar to middle-aged (54%/49%) and older females (56%/51%). AYAs were not at higher risk for decreased OS or EFS in the multivariable Cox analysis. Our findings remained consistent by cancer stage. Conclusion: Although Latin American AYAs with TNBC have more aggressive clinical features at diagnosis, survival outcomes were comparable with middle-aged and older women with TNBC, suggesting that age is not a risk factor for worse survival outcomes if treatment is given according to cancer stage. Our findings should be interpreted with caution given the lack of information on certain covariates such as comorbidities. Strategies for early detection in primary care and prompt referral for treatment initiation should be developed.

Use of ivermectin and factors associated with the prevention and/or treatment of COVID-19: a cross-sectional online survey in the province of Chincha, Peru.

Background: Peru has reported one of the highest mortality rates from COVID-19 worldwide. The Chincha province has been one of the most affected regions in Peru and the leading promoter of the use of ivermectin for the treatment of COVID-19. Therefore, our study aimed to evaluate the frequency of use and factors associated with the use of ivermectin for COVID-19 in Chincha. Methods: A cross-sectional study was conducted during the second wave of COVID-19 in Peru. For statistical analyses, frequencies and percentages were reported. Prevalence ratios (PR) with a 95% confidence interval (CI), and a p-value of 0.05 were used to determine statistical significance. SPSS version 22 (IBM Corp) program was used for the analyses. Results: A total of 432 participants were included in the study. A total of 67.6% (n = 292) of the participants used ivermectin during the COVID-19 pandemic. Of these, 20.20% (n=59) of the people used ivermectin for prophylactic purposes only, while 41.79% (n=122) used it as treatment for COVID-19 only, and 38.01% (n=111) used it for both reasons. The consumption of ivermectin was associated with being 50 years or older (PR:1.27, 95% CI:1.04-1.54), having a technical education level (PR:1.16, 95% CI:1.01-1.34), having had symptoms of COVID-19 with negative/no diagnosis (PR: 1.28, 95% CI: 1.07-1.53) or positive diagnosis (PR:1.38, 95% CI:1.18-1.61), or having had contact with infected people (PR:1.45, 95% CI:1.06-1.98). Conclusions: Most people in Chincha used ivermectin during the second wave of the COVID-19 pandemic. The main factors associated with the use of ivermectin for the prevention/treatment of COVID-19 were age ≥50 years, having a technical education level, having had symptoms with negative/no diagnosis or positive diagnosis, and contact with people infected with SARS-CoV-2.

Mortality Trends for Lung Cancer and Smoking Prevalence In Peru.

OBJECTIVES: Lung cancer continues to be  the leading cause of cancer-related deathworldwide. Have been reported high mortality rates from lung cancer in Latin America, but the disparities within the regions of Peru and under-reporting death certification reported prevent the inclusion of Peru in analysis of the mortality trends for lung cancer. We evaluated lung cancer mortality trends and smoking prevalence in Peru and its geographical areas. MATERIALS AND METHODS: We obtained the data from the registry of the Peruvian Ministry of Health between 2008 and 2017. Mortality rates per 100,000 person-years were computed using the world's SEGI population and trends were analyzed using the Joinpoint regression Program Version 4.7.0. Smoking prevalence was estimated from the Demographic and Family Health Survey. RESULTS: In Peru, mortality rates were roughly 1.3 times higher in males than in females. The coast region had significant downward trends among males, whereas the highlands region had significant upward trends among females. According to provinces, Apurimac showed an annually significant rise in both sexes (+10.6% in males, and +11.6% in females). In general, smoking prevalence was higher in males compared to females, principally among young adults.   Conclusions: Peru showed downward mortality trends in the last decade with variability across regions. Males had a higher smoking prevalence, principally among young adults. Public health interventions for smoking reduction should be implemented to reduce lung cancer mortality.

Prostate Cancer Mortality in Peru: An Update from 2003 to 2017.

OBJECTIVE: We estimated the mortality trends for prostate cancer in Peru and its geographical areas between 2003 and 2017. MATERIAL AND METHODS: We obtained recorded prostate cancer deaths from the Peruvian Ministry of Health Database between 2003 and 2017. Age-adjusted mortality rates per 100,000 men-year were computed with the direct method using the world standard SEGI population. We estimated the annual percent change (APC) using the Joinpoint regression program. RESULTS: A total of 38,617 prostate cancer deaths were reported between 2003 and 2017, with a mortality rate ranging from 18.21 to 19.94 deaths per 100,000 men-year. Since 2006, Peru has experienced a decrease of 2.2 deaths per year, whereas the mortality rate in the coastal region has declined by 2.9% per year.  The highlands and rainforest regions showed stable trends throughout the entire study period. According to provinces, only Moquegua had a significant decrease (APC: -6.0, 95%CI: -11.4, -0.2, p<0.05) from 2003 to 2017. CONCLUSIONS: Although mortality rates are decreasing, there is a high mortality burden by prostate cancer in Peru and by geographical regions, being mostly concentrated in the coastal region. The rainforest provinces deserve the most attention. Our findings suggest wide health care disparities among the different regions of Peru that need greater public health attention to reduce the burden of mortality by prostate cancer.
