The Cervical Cancer Treatment Gap in Mexico Under Seguro Popular, 2006-2016.

From 2005 to 2019, the Mexican government financed cervical cancer treatment for individuals without social security insurance through Seguro Popular's Fund for Protection against Catastrophic Health Expenses. To better understand the impact of this program on access to treatment, we estimated the cervical cancer treatment gap (the proportion of patients with cervical cancer in this population who did not receive treatment). To calculate the expected number of incident cervical cancer cases we used national surveys with information on insurance affiliation and incidence estimates from the Global Burden of Disease study. We used a national claims database to determine the number of cases whose treatment was financed by Seguro Popular. From 2006 to 2016, the national cervical cancer treatment gap changed from 0.61 (95% CI 0.59 to 0.62) to 0.45 (95% CI 0.43 to 0.48), with an average yearly reduction of -0.012 (95% CI -0.024 to -0.001). The gap was greater in states with higher levels of marginalization and in the youngest and oldest age groups. Although the cervical cancer treatment gap among individuals eligible for Seguro Popular decreased after the introduction of public financing for treatment, it remained high. Seguro Popular was eliminated in 2019; however, individuals without social security have continued to receive cancer care financed by the government in the same healthcare facilities. These results suggest that barriers to care persisted after the introduction of public financing for treatment. These barriers must be reduced to improve cervical cancer care in Mexico, particularly in states with high levels of marginalization.

Monitoring multidimensional aspects of quality of life after cancer immunotherapy: protocol for the international multicentre, observational QUALITOP cohort study.

INTRODUCTION: Immunotherapies, such as immune checkpoint inhibitors and chimeric antigen receptor T-cell therapy, have significantly improved the clinical outcomes of various malignancies. However, they also cause immune-related adverse events (irAEs) that can be challenging to predict, prevent and treat. Although they likely interact with health-related quality of life (HRQoL), most existing evidence on this topic has come from clinical trials with eligibility criteria that may not accurately reflect real-world settings. The QUALITOP project will study HRQoL in relation to irAEs and its determinants in a real-world study of patients treated with immunotherapy. METHODS AND ANALYSIS: This international, observational, multicentre study takes place in France, the Netherlands, Portugal and Spain. We aim to include about 1800 adult patients with cancer treated with immunotherapy in a specifically recruited prospective cohort, and to additionally obtain data from historical real-world databases (ie, databiobanks) and medical administrative registries (ie, national cancer registries) in which relevant data regarding other adult patients with cancer treated with immunotherapy has already been stored. In the prospective cohort, clinical health status, HRQoL and psychosocial well-being will be monitored until 18 months after treatment initiation through questionnaires (at baseline and 3, 6, 12 and 18 months thereafter), and by data extraction from electronic patient files. Using advanced statistical methods, including causal inference methods, artificial intelligence algorithms and simulation modelling, we will use data from the QUALITOP cohort to improve the understanding of the complex relationships among treatment regimens, patient characteristics, irAEs and HRQoL. ETHICS AND DISSEMINATION: All aspects of the QUALITOP project will be conducted in accordance with the Declaration of Helsinki and with ethical approval from a suitable local ethics committee, and all patients will provide signed informed consent. In addition to standard dissemination efforts in the scientific literature, the data and outcomes will contribute to a smart digital platform and medical data lake. These will (1) help increase knowledge about the impact of immunotherapy, (2) facilitate improved interactions between patients, clinicians and the general population and (3) contribute to personalised medicine. TRIAL REGISTRATION NUMBER: NCT05626764.

Reduction in the Treatment Gap for Breast Cancer in Mexico under Seguro Popular, 2007 to 2016.

As Mexico's government restructures the health system, a comprehensive assessment of Seguro Popular's Fund for Protection against Catastrophic Expenses (FPGC) can help inform decision makers to improve breast cancer outcomes and health system performance. This study aimed to estimate the treatment gap for breast cancer patients treated under FPGC and assess changes in this gap between 2007 (when coverage started for breast cancer treatment) and 2016. We used a nationwide administrative claims database for patients whose breast cancer treatment was financed by FPGC in this period (56,847 women), Global Burden of Disease breast cancer incidence estimates, and other databases to estimate the population not covered by social security. We compared the observed number of patients who received treatment under FPGC to the expected number of breast cancer cases among women not covered by social security to estimate the treatment gap. Nationwide, the treatment gap was reduced by more than half: from 0.71, 95% CI (0.69, 0.73) in 2007 to 0.15, 95%CI (0.09, 0.22) in 2016. Reductions were observed across all states . This is the first study to assess the treatment gap for breast cancer patients covered under Seguro Popular. Expanded financing through FPGC sharply increased access to treatment for breast cancer. This was an important step toward improving breast cancer care, but high mortality remains a problem in Mexico. Increased access to treatment needs to be coupled with effective interventions to assure earlier cancer diagnosis and earlier initiation of high-quality treatment.

National and state-level colorectal cancer mortality trends in Mexico, 1998-2018 / Tendencias nacionales y estatales de mortalidad por cáncer colorrectal en México, 1998-2018

Abstract: Objective: To describe the burden of colorectal cancer (CRC) in Mexico and understand mortality patterns based on sex, geography, and insurance status. Materials and methods: Mortality data (1998-2018) from the Instituto Nacional de Estadística y Geografía was obtained. We included colon (C18.0, C18.2-18.9) and rectal cancer ICD-10 codes (C19, C20), and estimated age-standardized national, state-level and health insurance mortality rates. We estimated the average annual percent change using joinpoint regression. Results: Between 1998 and 2018, the observed women and men mortality rate increased annually by 1.3 and 2.7%, respectively. Higher CRC mortality was observed in northern and more urbanized states and in groups with greater access to health insurance, which currently facilitates but does not routinely cover screening. Conclusion: CRC mortality in Mexico is increasing rapidly, with marked differences based on sex, geography, and insurance status. Our findings underscore potential benefits of increased investment in comprehensive screening, diagnosis, and treatment strategies for the general population.

Resumen: Objetivo: Describir la carga del cáncer colorrectal (CCR) en México y patrones de mortalidad según sexo, geografía y servicios de salud. Material y métodos: Se obtuvieron datos de mortalidad (1998-2018) del Instituto Nacional de Estadística y Geografía. Se incluyeron códigos CIE-10 de cáncer de colon (C18.0,C18.2-18.9) y recto (C19,C20). Se estimaron tasas de mortalidad nacionales, estatales y por servicio de salud, estandarizadas por edad. Se estimó el cambio porcentual anual promedio usando regresión joinpoint. Resultados: Entre 1998-2018, la tasa de mortalidad aumentó anualmente 1.3% en mujeres y 2.7% en hombres. Se observó mayor mortalidad por CCR en estados del norte, más urbanizados y con afiliación a servicios de salud que actualmente facilitan pero no cubren rutinariamente la detección. Conclusión: La mortalidad por CCR en México está aumentando rápidamente, con diferencias por sexo, geografía y afiliación. Los presentes hallazgos destacan los beneficios potenciales de mayor inversión en estrategias integrales de detección, diagnóstico y tratamiento para la población.

Falla multiorgánica secundaria a múltiples picaduras de abeja (Apis mellifera). Reporte de caso / Multiorgan failure secondary to multiple bee stings (Apis mellifera). Case report

Resumen Antecedentes: Las picaduras de abejas producen el mayor número de accidentes en muchos países. Se han descrito manifestaciones sistémicas inusuales tras la exposición al veneno de himenópteros. Con menor frecuencia se han documentado complicaciones neurológicas, infarto del miocardio, rabdomiólisis e insuficiencia renal. Este tipo de reacciones alérgicas sistémicas se producen en 0.3-7.5% de la población. Caso clínico: Varón de 39 años, talador, procedente de zona rural de Comayagua, Honduras, con historia de sufrir múltiples picaduras por abeja (Apis mellifera) acompañado de síncope, con trauma en región frontoparietal bilateral, de 3 h de evolución, fue atendido en servicio de salud en Comayagua y trasladado al Hospital Escuela Universitario, donde se continuó manejo por anafilaxia severa y extracción de múltiples aguijones. Posteriormente inició con estridor laríngeo, cianosis y disnea, por lo que se realizó intubación endotraqueal. Al examen físico se identificó edema facial importante, múltiples lesiones y excoriaciones, patrón respiratorio irregular, picaduras generalizadas, y presencia de hipoventilación en ambos campos pulmonares. Glasgow 13/15, hiperalgesia generalizada. Exámenes de laboratorio mostraron reacción leucemoide, neutrofilia severa, hiperhemoglobinemia, aumento de azoados, enzimas hepáticas elevadas, hipoalbuminemia, trastornos hidroelectrolíticos y acidosis mixta. Posteriormente progresó a rabdomiólisis y falla multiorgánica (hemodinámica, ventilatoria, renal), y falleció 48 h después de su ingreso. Conclusión: El número de picaduras y la cantidad de veneno inoculado son factores predictores de alta mortalidad y baja sobrevida. El traslado de forma oportuna y el manejo multidisciplinario son fundamentales para determinar un buen pronóstico en estos pacientes.

Abstract Background: Bee stings produce the greatest number of accidents in many countries. Unusual systemic manifestations have been described after exposure to Hymenoptera venom. Less frequently, neurological complications, myocardial infarction, rhabdomyolysis and renal failure have been documented. This type of systemic allergic reactions occur in 0.3-7.5% of the population. Case report: A 39-year- old male, logger, from the rural área of Comayagua, Honduras, had a history of suffering multiple bee stings (Apis mellifera) with a syncopal episode, trauma in parietal-forehead bilateral region and 3 hours of evolution. He was treated at a health service in Comayagua and transferred to the University School Hospital, where treatment was continued due to severe anaphylaxis and extraction of multiple stings. Later he began with stridor, cianosis and dyspnea, so endotracheal intubation was performed. Physical examination revealed significant facial edema, multiple lesions and excoriations, irregular respiratory pattern, generalized stings, and the presence of hypoventilation in both lung fields. Glasgow 13/15, generalized hyperalgesia. Laboratory tests showed leukemoid reaction, severe neutrophilia, hyperhemoglobinemia, increased nitrogen levels, elevated liver enzymes, hypoalbuminemia, hydroelectrolytic disorders and mixed acidosis. He later progressed to multiorgan failure and rhabdomyolysis (hemodynamics, ventilatory, renal), and died 48 hours after admission. Conclusion: The number of bites and the amount of poison inoculated are predictive factors of high mortality and low survival. The transfer in a timely manner and multidisciplinary management are essential to determine a good prognosis in these patients.

Clinical characteristics and treatment outcome of 485 patients with nonfunctioning pituitary macroadenomas.

Background. Nonfunctioning pituitary adenomas (NFPAs) are the most common benign lesions of the pituitary gland. Objective. To describe our experience with the management of NFPA. Study Design and Methods. Retrospective evaluation of NFPA patients managed between 2008 and 2013. We analyzed data regarding clinical presentation, imaging diagnosis, hormonal status, surgical, radiotherapeutic, and pharmacological treatment, and outcome. Results. 485 patients (54% men, mean age 53 ± 14 years) were followed for a median of 6.5 years. Visual field abnormalities and headaches were the presenting complaints in 87% and 66%, respectively. The diagnosis of NFPA was made incidentally in 6.2%, and 8% presented with clinical evidence of apoplexy. All patients harbored macroadenomas, with a median volume of 10306 mm(3); 57.9% had supra- or parasellar invasion and 19.6% had tumors larger than 4 cm. Central hypothyroidism, hypogonadism, and hypocortisolism were present in 47.2%, 35.9%, and 27.4%, respectively. Surgical resection was performed at least once in 85.7%. Tumor persistence was documented in 27% and was related to the size and invasiveness of the lesion. In selected cases, radiotherapy proved to be effective in controlling or preventing tumor growth. Conclusions. The diagnosis and treatment of NFPA are complex and require a multidisciplinary approach.

Pituitary apoplexy in nonfunctioning pituitary macroadenomas: a case-control study.

OBJECTIVE: Pituitary apoplexy (PA) is an endocrinologic emergency characterized by headache, visual abnormalities, and hemodynamic instability in the context of hemorragic infarction of a pituitary adenoma. Our goal was to estimate the incidence, precipitating factors, clinical characteristics, and outcome of PA in a cohort of patients with nonfunctioning pituitary macroadenomas (NFPMAs). METHODS: A retrospective, case-control study of 46 patients with PA and 47 controls matched for age, gender, and tumor invasiveness. Clinical, hormonal, and tumoral charactersitics, as well as the presence of potential precipitating factors and long-term outcome were evaluated using both bivariate and multivariate analysis. RESULTS: The prevalence of PA was 8%. Cases and controls were similar in regards to the prevalence of diabetes, hypertension, use of antiplatelet agents, and the presence of headaches and visual field defects. Oculomotor paralysis was present in 18% of cases and in none of the controls (P = .001). Prior use of dopamine agonists was significantly more frequent among cases than in controls on both bivariate and multivariate analysis. Pituitary hormone deficiencies were more common among cases than in controls on bivariate but not on multivariate analysis. Early and late surgical treatment was carried out in 11 and 25 patients, respectively; 11 patients were managed conservatively. Visual and endocrine outcomes were similar among the 3 groups. CONCLUSION: PA represents a life-threatening medical emergency. Prior use of dopamine agonists and the presence of oculomotor abnormalities clearly distinguished patients with NFPMA who developed PA from those who did not.

Acromegaly: role of surgery in the therapeutic armamentarium.

Acromegaly is a complex disease that requires the intervention of a multidisciplinary team. The most frequent clinical manifestations are growing of distal parts of the body and some areas of the face. Patients may also present arterial hypertension, diabetes mellitus, colonic polyps, cardiomegaly, neurological and endocrine changes secondary to the presence of a GH-secreting tumor in pituitary or extrapituitary origin, or eutopic hypothalamic GHRH hypersecretion and peripheral GHRH hypersecretion. Surgery is the first treatment used for most patients, regardless of the cause. In the great majority of cases, pituitary tumor can be removed through a transsphenoidal approach. Craniotomy is reserved for those cases with giant tumors, particularly when they grow toward the middle or posterior cranial fossa. Best surgical results are obtained when the tumor is confined into the sella turcica or if it has a regular suprasellar extension. When the disease cannot be controlled with surgery, medical treatment is indicated. Somatostatin analogues are included as the first line of medication, followed by dopamine agonist and growth hormone receptors antagonists. Radiation therapy can be also indicated in two main forms for residual tumor with medically refractory patients: radiosurgery for small tumors or fractionated stereotactic radiotherapy for larger ones.
