We described the retinal findings in patients with LR using different image modalities. Specifically, we report the findings with MSLI not previously described. While regular fundus photography may show mild changes in LR, the MSLI modality may show more significant findings assisting in the diagnosis and follow-up of this disease.

Antecedentes: Los datos sobre discapacidad visual (DV) en pacientes con diabetes son necesarios para orientar los recursos económicos y humanos que disminuyan su prevalencia. Objetivo: Estimar la prevalencia de DV relacionada con retinopatía diabética en pacientes con diabetes tipo 2 en un entorno hospitalario. Material y métodos: Estudio transversal realizado de 2014 a 2019 en una consulta externa de oftalmología. Cualquier DV se definió como agudeza visual corregida con agujero estenopeico en el ojo con mejor visión (≥ 0.24 logMAR). Se evaluó la presencia de retinopatía diabética, edema macular diabético (EMD) y cataratas. Resultados: Se incluyeron 840 pacientes; la mediana de duración de la diabetes fue de 15 años. La prevalencia de DV fue de 30 %. Se encontró retinopatía diabética en 62 % (30 % tenía retinopatía diabética que amenazaba la visión [RDAV]); 17 %, EMD y 3 %, cataratas. La razón de momios para DV moderada o de mayor gravedad fue de 9.02 para RDAV (p < 0.001), 5.89 para EMD referible (p = 0.001) y 2.51 para catarata (p = 0.006). Conclusión: Treinta por ciento de los participantes tenía algún grado de DV. La DV moderada o de mayor gravedad mostró una fuerte asociación con RDAV y EMD referible.

Background : Healthcare workers are at increased risk of SARS-CoV-2 infection. The positivity rates in hospitals that do not receive patients with COVID-19, such as the National Cancer Institute (INCan) in Mexico, and the associated factors are unknown. Objective : To assess the incidence and factors associated with SARS-CoV-2 infection in health workers at INCan. Methods : A cohort study of 531 workers who were followed for 6 months. RT-PCR analysis of saliva and nasopharyngeal swab samples were used in the baseline and to confirm cases during follow-up The incidence rate ratio was calculated according to the measured characteristics and the associated factors were calculated using logistic regression models. Results : Out of 531 workers, 9.6% tested positive for SARS-CoV-2, Being male (RR: 2.07, 95% CI: 1.1-3.8, p=0.02), performing administrative tasks (RR: 1.99, 95% CI: 1.0-3.9, p=0.04), and having relatives also working at INCan (RR: 3.7, 95% CI: 1.4-9.5, p<0.01) were associated with higher positivity rates. Discussion : Incidence of positive cases in health workers were similar to that reported in non-COVID hospitals from other countries . Conclusions : Even though active surveillance helped to detect a significant number of asymptomatic infections, it is still necessary to reinforce preventive measures in non-medical staff to prevent nosocomial transmission.

Type 2 diabetes mellitus (T2DM) is a chronic disease that affects a person's general well-being. Current evidence sets an association between psychological well-being and controlled metabolic parameters. People newly diagnosed with T2DM show higher prevalence of depression and anxiety symptoms. Cognitive behavioral therapy (CBT) has effectively improved psychological adjustment, but most studies do not specifically address recently diagnosed people nor usually include long-term follow-up measures. Objective We sought to assess changes in psychological variables in people with newly diagnosed diabetes who received a cognitive–behavioral intervention, within a comprehensive care program. Method 1208 adults with T2DM (≤5 years) who attended a national health institute in Mexico received a cognitive–behavioral intervention aimed at improving quality of life and reducing emotional distress that often interferes with diabetes control, as well as evaluating cognitive and emotional resources and social support. Measures of quality of life, diabetes-related distress, anxiety and depression questionnaires were compared at pre-test, post-test and follow up using Friedman's ANOVAs. Multiple logistic regression models evaluated glycosylated hemoglobin (HbA1c) and triglycerides control at post-test and follow up. Results Questionnaire measures and metabolic variables significantly decreased symptomatology at post-test and these changes maintained at follow-up. Significant associations were found between quality-of-life scores and HbA1c and triglycerides levels in post-test and follow-up. Diabetes-related distress scores increased the odds of having adequate HbA1c control at post-test. Conclusion This study contributes to the evidence on the importance of considering psychological factors as part of comprehensive diabetes care to improve quality of life and emotional burden and facilitate the achievement of metabolic goals.

To describe access to complete treatment in women with cervical cancer and state-sponsored insurance versus no insurance. We conducted a retrospective observational study. The source population consisted of women treated for cervical cancer from January 2000 to December 2015 in a tertiary care hospital. We included 411 women with state-sponsored insurance and 400 without insurance. We defined access to cervical cancer treatment as complete treatment (according NCCN/ESMO (National Comprehensive Cancer Network/European Society for Medical Oncology) standards) and timely initiation of treatment (less than 4 weeks). Clinical and sociodemographic characteristics were described and analyzed with logistic regression using complete treatment as the main outcome. A total of 811 subjects were included, the median age was 46 (IQR (Interquartile range) 42-50) years. Most of them were married (36.1%), unemployed (50.4%), and had completed primary school (44.0%). The most common clinical stages at diagnosis were II (38.2%) and III (24.7%). In the adjusted regression model, being married (OR (odds ratio): 4.3, 95% CI (confidence interval): 1.74-10.61) and having paid employment (OR: 2.79, 95% CI: 1.59-4.90) or state-sponsored insurance (OR: 1.54, 95% CI: 1.04-2.26) were positively associated with the possibility of having a complete treatment. Women with insurance were likely to be younger and receive timely treatment compared with uninsured women. Complete treatment was associated to insurance status and advanced stages of cervical cancer. State-sponsored insurance improves access to complete treatment. Government policies are needed to avoid social and economic inequity and provide better management of cervical cancer in our country.

Background: Data on visual impairment (VI) in patients with diabetes are necessary in order to guide economic and human resources for reducing its prevalence. Objective: To estimate the prevalence of diabetic retinopathy-related VI in patients with type 2 diabetes in a hospital-based setting. Material and methods: Cross-sectional study carried out from 2014 to 2019 in an ophthalmology outpatient clinic. Any VI was defined as corrected pin-hole visual acuity in the better eye of ≥ 0.24 logMAR. The presence of diabetic retinopathy (DR), diabetic macular edema (DME) and cataract was evaluated. Results: A total of 840 patients were included; median diabetes duration was 15 years. The prevalence of VI was 30%. DR was found in 62% of patients (30% had sight-threatening DR [STDR]), 17% had referable DME, and 3%, cataracts. The odds ratio for moderate or worse VI was 9.02 for STDR (p < 0.001), 5.89 for referable DME (p = 0.001), and 2.51 for cataract (p = 0.006). Conclusion: Thirty percent of participants had some degree of VI. Moderate or worse VI showed a strong association with STDR and referable DME.
