RESUMO
BACKGROUND: The Mexican Institute of Social Security (IMSS) is the largest health care provider in Mexico, covering about 48% of the Mexican population. In this report, we describe the epidemiological patterns related to confirmed cases, hospitalizations, intubations, and in-hospital mortality due to COVID-19 and associated factors, during five epidemic waves recorded in the IMSS surveillance system. METHODS: We analyzed COVID-19 laboratory-confirmed cases from the Online Epidemiological Surveillance System (SINOLAVE) from March 29th, 2020, to August 27th, 2022. We constructed weekly epidemic curves describing temporal patterns of confirmed cases and hospitalizations by age, gender, and wave. We also estimated hospitalization, intubation, and hospital case fatality rates. The mean days of in-hospital stay and hospital admission delay were calculated across five pandemic waves. Logistic regression models were employed to assess the association between demographic factors, comorbidities, wave, and vaccination and the risk of severe disease and in-hospital death. RESULTS: A total of 3,396,375 laboratory-confirmed COVID-19 cases were recorded across the five waves. The introduction of rapid antigen testing at the end of 2020 increased detection and modified epidemiological estimates. Overall, 11% (95% CI 10.9, 11.1) of confirmed cases were hospitalized, 20.6% (95% CI 20.5, 20.7) of the hospitalized cases were intubated, and the hospital case fatality rate was 45.1% (95% CI 44.9, 45.3). The mean in-hospital stay was 9.11 days, and patients were admitted on average 5.07 days after symptoms onset. The most recent waves dominated by the Omicron variant had the highest incidence. Hospitalization, intubation, and mean hospitalization days decreased during subsequent waves. The in-hospital case fatality rate fluctuated across waves, reaching its highest value during the second wave in winter 2020. A notable decrease in hospitalization was observed primarily among individuals ≥ 60 years. The risk of severe disease and death was positively associated with comorbidities, age, and male gender; and declined with later waves and vaccination status. CONCLUSION: During the five pandemic waves, we observed an increase in the number of cases and a reduction in severity metrics. During the first three waves, the high in-hospital fatality rate was associated with hospitalization practices for critical patients with comorbidities.

BACKGROUND: Permanent occupational disability is one of the most severe consequences of diabetes that impedes the performance of usual working activities among economically active individuals. Survival rates and worker compensation expenses have not previously been examined among Mexican workers. We aimed to describe the worker compensation expenses derived from pension payments and also to examine the survival rates and characteristics associated with all-cause mortality, in a cohort of 34,014 Mexican workers with permanent occupational disability caused by diabetes during the years 2000-2013 at the Mexican Institute of Social Security. METHODS: A cross-sectional analysis study was conducted using national administrative records data from the entire country, regarding permanent occupational disability medical certification, pension payment and vital status. Survival rates were estimated using the Kaplan-Meier method. Multivariate Cox proportional hazard model was used to estimate adjusted hazard ratios (HR) and 95 % confidence intervals (95 % CI) in order to assess the cohort characteristics and all-cause mortality risk. Total expenses derived from pension payments for the period were accounted for in U.S. dollars (USD, 2013). RESULTS: There were 12,917 deaths in 142,725.1 person-years. Median survival time was 7.26 years. After multivariate adjusted analysis, males (HR, 1.39; 95 % CI, 1.29-1.50), agricultural, forestry, and fishery workers (HR, 1.41; 95 % CI, 1.15-1.73) and renal complications (HR, 3.49; 95 % CI, 3.18-3.83) had the highest association with all-cause mortality. The all-period expenses derived from pension payments amounted to $777.78 million USD (2013), and showed a sustained increment: from $58.28 million USD in 2000 to $111.62 million USD in 2013 (percentage increase of 91.5 %). CONCLUSIONS: Mexican workers with permanent occupational disability caused by diabetes had a median survival of 7.26 years, and those with renal complications showed the lowest survival in the cohort. Expenses derived from pension payments amounted to $ 777 million USD and showed an important increase from 2000 to 2013.

AIM: To evaluate the progress of the Mexican Institute of Social Security Recovery Policy (IMSS-RP) in addressing the decline in essential health services caused by the COVID-19 pandemic. METHODS: We analyzed eleven indicators of essential health services from 35 IMSS state delegations. The assessment included ambulatory and hospital care indicators such as breast and cervical cancer screening, family medicine, dental and specialty visits, diabetes and hypertension visits and health outcomes, deliveries, and elective surgeries. We analyzed the period before (January 2018-March 2021) and during (April 2021-June 2023) the implementation of the IMSS-RP. Statistical analysis to determine the association of the policy with service indicators and the change in their trends included an interrupted time series analysis and Poisson Generalized Estimating Equation models. RESULTS: The volume of services showed substantial declines during the first year of the COVID-19 pandemic, reaching between 11 and 81% of pre-pandemic levels. All services increased significantly during the first 27 months of the IMSS-RP implementation; specialty visits, cervical and breast cancer screening, and diabetes control exceeded pre-pandemic levels (103%,112%,103%, and 138%, respectively). However, only deliveries and the percentage of patients with controlled diabetes and hypertension showed a stable increase following the IMSS-RP implementation, whereas the remaining services showed an initial increase but began to decrease over time. CONCLUSIONS: After 27 months of implementation, IMSS-RP achieved progress in increasing the volume of essential health services and improving chronic disease control. However, declining trends in several services signal the need to focalize the policy.

BACKGROUND: Several studies in type 2 diabetes patients have shown significant associations between the SOD2 gene Val16Ala polymorphism and albuminuria, but this association has not been explored in the Mexican population. METHODS: We evaluated the association between the SOD2 gene Val16Ala polymorphism (rs4880) and macroalbuminuria in a sample of 994 unrelated Mexican type 2 diabetes patients. The study included 119 subjects with urinary albumin >300 mg/dL and 875 subjects with urinary albumin ≤ 30 mg/dL. Genotyping of the SOD2 gene Val16Ala SNP was carried out with Real-Time Polymerase Chain Reaction (RT-PCR). RESULTS: The frequency of the TT genotype was 6.7% higher in participants with macroalbuminuria than in the normoalbuminuria group (16.8% vs. 10.1%). Using a logistic regression analysis, we observed that individuals with the CC genotype had significantly lower risks of macroalbuminuria than those with the TT genotype (OR=0.42, p=0.034). We carried out a meta-analysis combining our data with data from four previous studies and estimated an odds ratio (95% CI) for the C allele (with respect to the reference T allele) of 0.65 (0.52-0.80, p<0.001). CONCLUSIONS: A significant association was found between the SOD2 Val16Ala polymorphism and macroalbuminuria in a sample of Mexican type 2 diabetes patients.

Background: Cardiopulmonary bypass generates an exacerbated response that may lead to sepsis. Objective: To describe the association between procalcitonin levels and sepsis diagnosis in cardiovascular surgery subjects with cardiopulmonary bypass. Methods: A case-series study was conducted in 142 patients. Serum procalcitonin levels were measured at 24 hours and at 72 hours after surgery using a point of care testing based on quantitative immunochromatographic method. To assess association between procalcitonin levels and sepsis status, we calculated area under the curve (AUC) and sensitivity, specificity, and predictive values for the best cut-off point. Results: From 142 patients studied, 7 developed sepsis after surgery (4.9%). For 24-hours procalcitonin levels AUC was 0.921 and best cut-off point was 3.8 ng/mL (sensitivity 0.857 and specificity 0.904). In the case of 72-hours procalcitonin levels, we observed a value of 0.868 for AUC and best cut-off point was 8.4 ng/mL (sensitivity 0.86 and specificity 0.97). Conclusions: Procalcitonin levels at 24 and 72 hours after cardiovascular surgery with cardiopulmonary bypass are associated with sepsis presence at cut-off points of 3.8 and 8.4 ng/mL respectively.
Introducción: la circulación extracorpórea durante la cirugía cardiovascular genera una respuesta exacerbada que puede asociarse con sepsis. Objetivo: describir la asociación entre los niveles de procalcitonina y el diagnóstico de sepsis en sujetos de cirugía cardiovascular con circulación extracorpórea. Material y métodos: se realizó un estudio de serie de casos en 142 pacientes. Los niveles de procalcitonina fueron medidos a las 24 horas y a las 72 horas después de la cirugía. Para evaluar la asociación entre los niveles de procalcitonina y la identificación de sepsis, se calculó el área bajo la curva (AUC) y la sensibilidad y especificidad identificando el mejor punto de corte. Resultados: de un total de 142 pacientes estudiados, 7 desarrollaron sepsis (4.9%). En los niveles de procalcitonina en las 24 horas, el AUC fue de 0.921 y el mejor punto de corte fue 3.8 ng/mL (sensibilidad de 0.857 y especificidad de 0.904). En el caso de los niveles de procalcitonina a las 72 horas, observamos un AUC de 0.868 y el mejor punto de corte fue 8.4 ng/mL (sensibilidad de 0.86 y especificidad de 0.97). Conclusiones: los niveles de procalcitonina a las 24 y 72 horas de la cirugía cardiovascular con circulación extracorpórea se asociaron con la presencia de sepsis con los puntos de corte de 3.8 ng/mL y 8.4 ng/mL respectivamente.

BACKGROUND: Primary care level close monitoring of mild COVID-19 patients has shown to provide a risk reduction in hospitalization and death. We aimed to compare the risk of all-cause death among COVID-19 ambulatory patients who received and did not receive telephonic follow-up in primary health care settings. METHODS: A secondary database analysis, 2-group comparative study, was conducted with data from the medical information systems of the Mexican Institute of Social Security. A total of 1,498,808 ambulatory patients aged 20 years old and over and with laboratory confirmed SARS-CoV-2 by PCR or rapid antigen test were analyzed. Of them, 535,898 (35.8%) where followed by telephonic calls. The cases were attended from October 14, 2020, to April 10, 2022. Death incidence was evaluated. To assess the association between death and telephonic follow-up we calculated risk ratio using a multivariate logistic model. RESULTS: Case fatality rate was 1.29% in the patients who received telephonic follow-up and 2.95% in the cases who did not receive phone calls. Medical history of chronic kidney disease, COPD, cardiovascular disease, tobacco consumption and diabetes were associated with increased risk of death. In the multivariate model, telephonic follow-up was associated with lower risk of all-cause death, with an adjusted risk ratio of 0.61 (95% confidence interval from 0.59, 0.64). CONCLUSION: Our data suggest that telephonic follow-up is associated with a risk of death reduction in adult outpatients with mild COVID-19, in the context of a multimodal strategy in the primary health care settings.

BACKGROUND: Burkholderia cepacia (B. cepacia) has been the causal agent of infectious hospital outbreaks. METHODS: a case-controls study was conducted to describe an outbreak of urinary tract infection associated to lubricant-gel contaminated with B. cepacia. Patients who developed UTIsc were included in this study. Their clinical data, urine cultures, antiobiograms and the molecular bacterial analysis were analyzed. RESULTS: the urine culture was positive in 101 (55.8 %); the bacterial strains isolated were: B. cepacia 30.7 %, Escherichia coli 22.7 %, Enterococcus faecalis 9.9 %, Enterococcus spp. 8.9 %. They were 31 patients with B. cepacia isolation that was taken as the cases group and 63 with UTIsc due to another organism as control group. The Charlson comorbidity index was 5.3 ± 1.8 for cases and 4.5 ± 1.2 for controls. The factors associated with death were: heart disease, diabetes, pneumonia, bacteremia and UTIsc B. cepacia. CONCLUSIONS: the lubricant gel used for urinary catheter placement originated the outbreak. Heart disease, pneumonia, bacteremia and UTIsc B. cepacia were related to patients' death.

Background: In a context where the prevalence of Diabetes Mellitus and Hypertension has increased significantly in recent years, kidney diseases become important for the potential demand for specialized health care and resources required. Objective: To analyze the geographical distribution of Diabetic Nephropathy (DN) and Renal Insufficiency (RI) based on the medical consultations given in first-level units of IMSS during 2019, to identify the medical units with the highest burden of care. Material and methods: Ecological-exploratory study in which indicators were estimated for every thousand persons in relation to medical consultations given by ND and RI according to service time, first-level medical unit (UMF) and representation to analyze the magnitude and geographic distribution at the national level. Results: 45% of medical consultations were by ND and 52.4% by RI. The highest burden per DN was registered in UMF No. 50 Cd. Juarez (Chihuahua) and No. 49 Gabino Barreda (Veracruz Sur), with 1.7 first-time medical consultations and 148.3 subsequent medical consultations per 1,000 persons, respectively. While in UMF No. 40 Manlio Fabio Altamirano and No. 25 Cotaxtla, in Veracruz Norte, the highest burden was for RI, with 4.9 first-time medical consultations and 134.2 subsequent medical consultations per 1000 persons, respectively. Conclusions: The results could contribute to strengthening of medical units where it is necessary and the efficient allocation of resources available to meet the demand for health services of ND and RI in IMSS.

The COVID-19 pandemic established a new challenge for health services in Mexico, which is why these services faced the challenge of responding to the affected people, by providing them services with opportunity, efficiency, effectiveness and safety. The Instituto Mexicano del Seguro Social (IMSS, Mexican Institute for Social Security) gave medical attention to the larger number of affected people: towards the end of September, 2022, 3,335,552 patients were registered, who represented 47% of the total (7,089,209) of confirmed COVID-19 cases since the beginning of the pandemic in 2020. Of all the cases treated, 295,065 (8.8%) required hospitalization. In addition of new scientific evidence and the implementation of best practices in medical care and directive management (with the general objective of improvement of the processes in hospital attention, even without an effective treatment at the time), we presented an evaluation, supervision method with a comprehensive (involving the three levels of health services) and analytic (structure, process, result and directive management components) approach. The achievement of specific goals and lines of action was established in a technical guideline with health policies for the COVID-19 medical care. These guidelines were instrumented with a standardized evaluation tool, a result dashboard and a risk assessment calculator, improving the quality of medical care and directive management by the multidisciplinary health team.
La pandemia por COVID-19 puso a prueba la prestación de servicios de los sistemas de salud en México, por lo que estos enfrentaron el reto de responder a la necesidad de las personas afectadas al otorgar servicios oportunos, eficientes, eficaces y seguros. El Instituto Mexicano del Seguro Social (IMSS) atendió el mayor número de personas afectadas: al cierre de septiembre del 2022, se registraron 3,335,552 pacientes atendidos, quienes representaron 47% del total (7,089,209) de casos confirmados desde el inicio de la pandemia en 2020. De los casos notificados por el IMSS, 295,065 (8.8%) requirieron hospitalización. Mediante un atento seguimiento de la evolución de la evidencia científica (que permitió identificar y adoptar las mejores prácticas de atención médica y gestión directiva para fortalecer los procesos sustantivos en la atención hospitalaria, aun sin un tratamiento eficaz), se integró un método de evaluación, supervisión y asesoría, con enfoque integral (que involucró los tres niveles de atención médica) y analítico (componentes de estructura, proceso, resultado y gestión directiva). Los objetivos de la atención y las líneas de acción se describieron en una guía técnica que estableció las políticas de atención médica al COVID-19. Asimismo, fue instrumentado con una cédula de evaluación estandarizada, un tablero de control de resultados y una herramienta de estratificación del riesgo. Con ello se mejoró la calidad de atención por medio de la participación del personal directivo y de equipos multidisciplinarios de salud, los cuales permitieron la toma de decisiones clínicas y gerenciales.

BACKGROUND: Different interventions have been implemented worldwide for the house-hold monitoring of patients with mild COVID-19 to reduce the burden of healthcare systems and guarantee quality of care. Telephone follow up and treatment kits have not been evaluated in the context of a national-wide primary care program. AIM OF THE STUDY: To compare the risk of hospitalization and death for COVID-19 between ambulatory patients who received and those who did not receive a treatment kit and telephone follow-up in a developing country METHODS: A two-group comparative analysis was conducted using data from the medical information systems of the Mexican Institute of Social Security. We included a total of 28,048 laboratory-confirmed SARS-CoV-2 patients: 7,898 (28.2%) received a medical kit and 20,150 (71.8%) did not. The incidence rates of hospitalization and death combined were calculated. To identify significant associations between hospitalization or death and treatment medical kits, we calculated the risk ratios using a multivariate logistic model. RESULTS: The incidence of hospitalization was 6.14% in patients who received a kit and 11.71% in those who did not. Male sex, age, and a medical history of obesity, hypertension, diabetes, immunosuppression, or kidney disease were associated with increased risk of hospitalization or death. The risk rates were reduced in patients who received a medical kit or telephone follow-up. In the multivariate model, receiving a medical kit was associated with a lower risk of hospitalization or death from COVID-19: adjusted risk ratio 0.41 (95% confidence interval 0.36-0.47). CONCLUSION: Use of a multimodal strategy may reduce the risk of hospitalization and death in adult outpatients with mild COVID-19.

INTRODUCTION: The increasing resistance to antibiotics is a public health problem and an imminent therapeutic challenge in hospitals. In this report we aimed to analyze the relationship between antimicrobial resistance and antibiotic consumption in a third-level pediatric hospital. METHODOLOGY: A cross-sectional analysis was conducted using the information from the microbiology and pharmacy databases of the Pediatric Hospital "Doctor Silvestre Frenk Freund", during the period 2015-2018. Prevalence of antimicrobial resistance by microorganisms and dispensed grams of selected antibiotics were calculated annually. Antibiotic resistance trend over the time was evaluated using the Chi-square trends test and to assess the correlation between the dispensed grams of antibiotics with their antimicrobial resistance prevalence, we calculated the Pearson's coefficient (r). RESULTS: A total of 4,327 isolated bacterial samples were analyzed (56.5% Gram-positive and 44.5% Gram-negative). Most frequently isolated microorganisms were coagulase-negative staphylococci (CoNS), E. coli, K. pneumoniae, P. aeruginosa and S. aureus. We found a significant increase in resistance to clindamycin and oxacillin for CoNS and significant decrease in nitrofurantoin and amikacin resistance for E. coli and K. pneumoniae. We observed a strong positive and statistically significant correlation between amikacin resistance prevalence and amikacin dispensed grams for P. aeruginosa (r = 0.95, p = 0.05). CONCLUSIONS: The antibiotic resistance profile showed by our study highlights the need of an appropriate antibiotic control use in the Hospital setting.

BACKGROUND: Mexico has reported high death and case fatality rates due to COVID-19. Several comorbidities have been related to mortality in COVID-19, as hypertension, diabetes, coronary heart disease, chronic obstructive lung disease and chronic kidney disease. AIMS: To describe the main clinical characteristics of COVID-19 in the major social security institution in Mexico, as well as the contribution of chronic comorbidities and the population attributable fraction related to them. METHODS: Data for all patients with a positive test for SARS-CoV-2 in the institutional database was included for analysis. Demographic information, the presence of pneumonia and whether the patient was hospitalized or treated at home as an outpatient as well as comorbidities were analyzed. Case fatality rate was estimated for different groups. Odds ratios with 95% confidence intervals from a logistic regression model were estimated, as well as the population attributable fraction. RESULTS: By November 13, 2020, 323,671 subjects with COVID-19 infection have been identified. Case fatality rate is higher in males (20.2%), than in females (13.0%), and increases with age. Case fatality rate increased with the presence of obesity, hypertension and/or diabetes. Age and sex were major independent risk factors for mortality, as well as the presence of pneumonia, diabetes, hypertension, obesity, immunosuppression, and end-stage kidney disease. The population attributable fraction due to obesity in outpatients was 16.8%. CONCLUSIONS: Major cardiovascular risk factors and other comorbidities increase the risk of dying in patients with COVID-19. Identification of populations with high fatality in COVID-19, provides insight to deal with this pandemic by health services in Mexico.

There are no studies in Mexico comparing Hepatitis C virus (HCV) epidemiology among Health Institutions. In this report, we described the deaths and hospitalizations due to HCV in the three main Health Institutions in Mexico: the Mexican Institute of Social Security, the Institute of Social Security for State Workers and the Ministry of Health, during the period 2004-2017. A secondary analysis was carried out across the country using hospital administrative death databases. Adult deaths and hospitalizations rates were calculated in reference to the total affiliated population and all-cause in-hospital mortality risk were also evaluated. There were 7,914 deaths and 9,002 hospitalizations due to HCV. Mortality and hospitalization rates of these three institutions together showed a continuous decrease over the analyzed time: the mortality rate dropped from 1.25 to 0.41 per 100,000 affiliates during 2004 and 2017, respectively (66.9% of change), and the hospitalization rate dropped from 2.19 to 0.39 per 100,000 affiliates (81.9% of change). All-cause in-hospital survival accounted for 89.6%. Older age groups and Ministry of Health hospitalizations were associated with higher all-cause in-hospital death rates. In conclusion, the mortality and hospitalizations rates found in this study reflect a decrease in the burden of HCV in Mexico.

AIMS: To describe the annual incidence of type 1 diabetes in children and adolescents insured by the Mexican Institute of Social Security, the main health provider in Mexico, during 2000-2018. METHODS: We conducted a secondary data analyses using the incidence registers from the Epidemiological Surveillance Coordination of the Mexican Institute of Social Security collected during 2000-2018. Incident type 1 diabetes cases (age 19â¯years old and below) were identified using ICD-10-CM E10 diagnostic codes. Age, sex, and geographical region and seasonal-specific incidence were calculated with their corresponding annual percentage change (APC) as well. RESULTS: In the period 2000-2018, the number of incident cases with type 1 diabetes decreased from 3.4 to 2.8 per 100,000 in insured for subjects below 20â¯years old. We observed an increase in the 2000-2006, followed by a decrease for the 2006-2018 period (APC +16.1 and -8.7 respectively). Females and children <5â¯years old had a significant decrease in the incidence rate, while inhabitants in Central Mexico showed a significant increase. No difference was found in incidence between seasons. CONCLUSIONS: Our study describes significant fluctuations of the incidence of type 1 diabetes during the period 2000-2018, which appeared to correspond to influenza outbreaks, among Mexican children and adolescents.

BACKGROUND: Childhood obesity is a major health problem in Mexico. Obesity prevalence estimated by body mass index (BMI) is almost half than that estimated by percent body fat (%BF) in the Childhood Obesity pediatric cohort (COIPIS). OBJECTIVE: We performed a genome-wide association study (GWAS) of BMI and %BF in 828 children from the COIPIS to identify markers of predisposition to high values for both phenotypes used for obesity classification. METHODS: For the GWAS we used the LAT Axiom 1, Affymetrix and 2.5 million single loci from the 1000 Genomes Phase 3 imputation panel. We used a linear model, adjusted by age, sex, and Amerindian ancestry assuming an additive inheritance model. RESULTS: Genome-wide significance (p ≤ 5.0 × 10-8) and 80% of statistical power was reached for associations of two loci in two genes (CERS3 and CYP2E1) to BMI. Also, 11 loci in six genes (ANKS1B, ARNTL2, KCNS3, LMNB1, SRGAP3, TRPC7) reached genome-wide significance for associations to %BF, though not 80% of statistical power. DISCUSSION: None of the SNPs were previously reported as being associated to BMI or %BF. In addition, different loci were found for BMI and %BF. These results highlight the importance of gaining deeper understanding of genetic markers of predisposition to high values for the phenotypes used for obesity diagnosis.

BACKGROUND: Little is known about diabetes-related major lower extremity amputations (DMLEA) burden in México. AIM OF THE STUDY: To describe DMLEA hospitalization rates, in-hospital survival rates, characteristics associated with all-cause in-hospital mortality and direct costs of hospitalization during the 2005-2015 period, in the two principal Health Institutions in Mexico: the Mexican Institute of Social Security (IMSS) and the Ministry of Health (MoH). METHODS: A secondary data analysis was conducted using hospital discharge information obtained from administrative databases. Non-traumatic DMLEA hospitalizations in adults aged 20 years and over were analyzed. Hospitalization characteristics and in-hospital all-cause mortality risk were also assessed. Direct costs of hospitalization including length of hospital stay, surgical procedure, wound care and medical emergency consultation were accounted in U.S. dollars (USD, 2015). RESULTS: There were 34,051 DMLEA hospitalizations and 1,268 in-hospital deaths. DMLEA hospitalizations rates increase from 4.71-6.12 × 100,000 affiliates during 2005 and 2015 respectively for both institutions together. Females and age ≥60 years were associated with all-cause in-hospital death. The all-period direct costs of hospitalization amounted to $132.51 million USD ($86.30 in the IMSS and $46.21 in the MoH), and showed a sustained increment: from $4.14 million USD in 2005 to $24.84 million USD in 2015 (percentage increase 499.3%). CONCLUSIONS: In-hospital mortality was 3.7%. Female sex and age ≥60 years were characteristics associated with all-cause in-hospital death. The increase in the number of DMLEA hospitalizations and their direct costs, reflects a negative progression of diabetes in the two largest Health Institutions in Mexico.

Background: Cancer represents an important issue in health, with the economic impact that it takes. The aim of this paper is to analyze the epidemiological characteristics of a population with social security who was diagnosed with some type of cancer and required a disability pension. Methods: Observational study, retrolective cohort type, carried out at the Instituto Mexicano del Seguro Social (IMSS) with IMSS beneficiaries ruled with a state of disability due to malignancy during the period 2006 to 2012. Results: 13 633 cases were studied, observing an increasing behavior among the years mentioned. The age average of the rightful claimants ruled was 47.75 years; the main causes of disability due to malignant tumors were breast, colon and brain cancer. The definitive opinions represented the 49.66%, which are likely to generate a constituent amount for the IMSS. It is important to have data of the survival in relation to the most frequent malignant tumors, which can provide information about the severity and prognosis of these diseases. Conclusions: The results obtained lead to discuss the effectiveness of programs established on the prevention and early detection of non-communicable diseases, mainly in breast cancer, since the impact that has this type of suffering may involve a major financial problem for the IMSS because of the payment of constituent amounts.
Introducción: El cáncer representa una problemática importante en salud, con el impacto económico que conlleva. El objetivo de este trabajo fue analizar las particularidades epidemiológicas de una población con seguro social en quien se diagnosticó algún tipo de cáncer y requirió una pensión de invalidez. Métodos: Estudio observacional, tipo cohorte retrolectiva, llevado a cabo en el Instituto Mexicano del Seguro Social con derechohabientes del IMSS dictaminados con un estado de invalidez por algún tumor maligno durante el periodo 2006 a 2012. Resultados: Se estudiaron 13 633 casos, con un comportamiento ascendente en el periodo estudiado, la edad promedio de dictaminación fue de 47.75 años; las principales causas de invalidez por tumores malignos fueron cáncer de mama, de colon y de encéfalo; los dictámenes definitivos representaron el 49.66%, que son susceptibles de generar un monto constitutivo al IMSS. Resulta importante contar con datos de sobrevida en relación a los tumores malignos más frecuentes, que puedan aportar información sobre la severidad y pronóstico de estas enfermedades. Conclusiones: Los resultados obtenidos conducen a debatir la efectividad de los programas establecidos sobre prevención y detección temprana de enfermedades no transmisibles, principalmente en cáncer de mama, debido a que el impacto que tiene este tipo de padecimientos puede implicar una problemática financiera importante para el IMSS por el pago de montos constitutivos.

Introducción: en un contexto donde la prevalencia de diabetes mellitus e hipertensión arterial ha aumentado significativamente en años recientes, las enfermedades renales adquieren importancia por la potencial demanda de atención especializada y de recursos en salud que requieren. Objetivo: analizar la distribución geográfica de la nefropatía diabética (ND) y la insuficiencia renal (IR) con base en las consultas otorgadas en unidades de primer nivel del Instituto Mexicano del Seguro Social (IMSS) durante 2019, para identificar las unidades médicas con mayor carga de atención. Material y métodos: estudio ecológico-exploratorio en el que se estimaron indicadores por cada mil derechohabientes en relación a las consultas otorgadas por ND e IR según la ocasión de servicio, la unidad médica familiar (UMF) de primer nivel y la representación. Se utilizó estadística espacial para analizar dichos indicadores. Resultados: el 45% de las consultas otorgadas fue por ND y el 52.4% por IR. La mayor carga por ND se registró en la UMF No. 50 de Cd. Juárez (Chihuahua) y en la No. 49 Gabino Barreda (Veracruz Sur), con 1.7 consultas de primera vez y 148.3 subsecuentes por mil derechohabientes, respectivamente. Mientras que en la UMF No. 40 Manlio Fabio Altamirano y No. 25 Cotaxtla, en Veracruz Norte, la mayor carga fue por IR, con 4.9 consultas de primera vez y 134.2 subsecuentes por mil derechohabientes, respectivamente. Conclusiones: los resultados podrían contribuir al fortalecimiento de las unidades médicas que así lo requieran y en la distribución eficiente de los recursos disponibles para atender la demanda de servicios de salud de ND e IR en el IMSS
Background: In a context where the prevalence of Diabetes Mellitus and Hypertension has increased significantly in recent years, kidney diseases become important for the potential demand for specialized health care and resources required. Objective: To analyze the geographical distribution of Diabetic Nephropathy (DN) and Renal Insufficiency (RI) based on the medical consultations given in first-level units of IMSS during 2019, to identify the medical units with the highest burden of care. Material and methods: Ecological-exploratory study in which indicators were estimated for every thousand persons in relation to medical consultations given by ND and RI according to service time, first-level medical unit (UMF) and representation to analyze the magnitude and geographic distribution at the national level. Results: 45% of medical consultations were by ND and 52.4% by RI. The highest burden per DN was registered in UMF No. 50 Cd. Juarez (Chihuahua) and No. 49 Gabino Barreda (Veracruz Sur), with 1.7 first-time medical consultations and 148.3 subsequent medical consultations per 1,000 persons, respectively. While in UMF No. 40 Manlio Fabio Altamirano and No. 25 Cotaxtla, in Veracruz Norte, the highest burden was for RI, with 4.9 first-time medical consultations and 134.2 subsequent medical consultations per 1000 persons, respectively. Conclusions: The results could contribute to strengthening of medical units where it is necessary and the efficient allocation of resources available to meet the demand for health services of ND and RI in IMSS.

BACKGROUND: Oropharyngeal mucositis (OM) is one of the main side-effects of oncological therapy. There is no treatment to prevent its occurrence, but some zinc-based therapies have been proven to help in decreasing its in-tensity. The objective of this study was to determine the effect of zinc in OM in children with acute leukemia in the early stages of oncological treatment. MATERIAL AND METHODS: This quasi-experimental study evaluated OM in 2 groups (control group: conventional hospital management, and experimental group: administration of 50 mg of zinc gluconate daily plus conventional hospital management). OM severity was recorded at a two-month follow-up. RESULTS: Forty-nine patients (26 in the control group and 23 in the experimental group) were included. The mean age of the patients was 11.1 ± 2.7 years; 65.3% had a diagnosis of pre-B acute lymphoblastic leukemia. The incidences of OM in the control group and the experimental group were 46.2% and 26.1%, respectively, but the difference was not significant. Based on a negative binomial regression model, females had, on average, 1.5 more days with OM (p = 0.002), and patients assigned to the experimental group had, on average, 2 less days with OM than the control group (p = 0.001). The pain score was higher in the control group (p = 0.0009), as was the mean score on the WHO scale (p = 0.0012). CONCLUSIONS: Zinc facilitated a reduction in the severity and duration of OM; further studies focusing on children are needed to confirm the effects of this trace element
