RESUMO
The objective of this study was to evaluate the clinical files of patients with RRMS who started rituximab (RTX) compared with a second-line treatment (natalizumab (NTZ) or fingolimod (FTY)). This was a historical cohort study. We compared the effect according to the Expanded Disability Status Scale (EDSS) and the number of relapses in RRMS patients receiving these treatments after a mean period of 12 months. We found a statistically significant difference (p < 0.001) when comparing the EDSS scores and the annual relapse rates of patients receiving RTX with those receiving NTZ or FTY. This study is essential for our clinical practice, since patients with limited treatment options represent a challenge with regard to the management of their medical care. However, clinical trials and prospective studies with long follow-up periods are necessary to provide sufficient evidence on the efficacy of RTX and thus include this treatment in the therapeutic profile of patients with MS.
RESUMO
BACKGROUND: Multiple sclerosis affects more than 2 million people. Clinical decisions are performed under evidence-based medicine. The appearance of new disease-modifying therapies and changes in diagnostic criteria complicates the decision-making process in clinical practice. OBJECTIVES: To characterize the criteria for radiologically isolated syndrome (RIS), clinically isolated syndrome (CIS), and relapsing-remitting multiple sclerosis (RRMS) by Mexican neurologists in a real-world setting. METHODS: A two-round modified Delphi method (RAND/UCLA) was applied. RESULTS: In RIS, LP, spinal cord MRI and VEP should be included in diagnostic testing; DMT initiation is not necessary. A follow-up MRI within 3 months are recommended. In CIS, corticosteroid therapy should be initiated at first relapse; both simple and Gd-enhanced MRI is mandatory. LP, selective blood tests, and NMO-IgG/AQP4 antibodies should be performed as complementary. IFN beta or GA were the most suitable DMTs for treating high-risk CIS. Patients with RRMS should begin with DMT at diagnosis, include a follow-up MRI if a patient had 2 relapses within 6 months. GA and oral DMTs are the most eligible DMTs for mild RRMS. Monoclonal antibodies-based therapy is chosen when disability is present. Radiological criteria for switching DMT included >1 Gd+ lesion and >2 new T2 lesions. CONCLUSIONS: Although many coincidences, there are still many hollows in the medical attention of MS in Mexico. This consensus recommendation could be helpful to implement better evidence-based recommendations and guidelines in a real-world setting.

Resumen Se realiza una revisión sobre el riesgo de los pacientes que padecen diabetes mellitus en el contexto de morbimortalidad general y relacionada a infección por el coronavirus 2 del síndrome respiratorio agudo grave (SARS-CoV-2). Así mismo se repasan las recomendaciones generales, de alimentación y de la prevención de las comorbilidades que más frecuentemente padecen dichos enfermos. Finalmente se hace una revisión de las recomendaciones farmacológicas sobre el tratamiento tanto oral como parenteral en el paciente ambulatorio, en la hospitalización y en estados críticos infectados por el SARS-CoV-2.
Abstract A review is carried out to examine the risk of patients suffering from diabetes mellitus in the context of general morbidity and mortality and related to infection by SARS-CoV-2. Likewise, the general recommendations for food and the prevention of comorbidities that most these patients suffer most frequently are also studied. Finally, a review of the pharmacological recommendations on both oral and parenteral treatment in the outpatient, in hospitalization and in critical states infected with SARS-CoV-2 is made.

Long-term exposure to air pollution has been linked with the development of neurodegenerative diseases. The proposed mechanisms include neuroinflammation and brain oxidative stress. Multiple sclerosis (MS) is a neurodegenerative disease with an auto-immune physiopathology and some studies have associated it with long-term exposure to airborne particulate matter. In this opinion we discuss the current body of knowledge regarding air pollution and the risk of MS as well as MS relapses. Also, its relevance in the case of Mexico City is discussed.

Objective: Sarcopenia is among the most deleterious effects of aging. The objective of this study was to analyze the relationship between performance tests and muscular volume over the life span of male and female participants. Method: A correlation study was conducted with healthy individuals (50 males and 47 females) between the ages of 20 and 94; the study group included active older people, sedentary younger people, and young athletes. Muscular volume was determined by tomography and muscular performance (4-meter speed tests [4 MSTs], chair test, and handgrip test), and a correlation analysis between the groups was performed. Results: Sex-related differences were observed between the variables; in males, muscle volume and functional parameters were closely related with age and physical activity, whereas in females, they were not related at all. Conclusion: Male and female muscle volume and performance demonstrate strong differences, which should be considered during clinical evaluations of sarcopenia.
RESUMO
INTRODUCTION: The clinical course of multiple sclerosis (MS) varies widely. The natural history of the disease has shown that approximately 50% of patients that begin with a relapsing-remitting clinical course will have a progressive course about 10 years after disease onset and will need some kind of aid to walk. The expression of apolipoprotein E (ApoE) increases in nerve tissue undergoing regeneration and the ApoE epsilon-4 allele is associated with abnormal neural repair. Several different reports indicate that the ApoE epsilon-4 allele is associated with a greater progression of disability in patients with MS, although this is still a matter of debate. PATIENTS AND METHODS: We analyse the clinical characteristics of 99 patients diagnosed with MS, we describe the correlation between the presence or absence of the ApoE epsilon-4 allele and the age of onset, clinical subtype, progression of the disease, score on the Expanded Disability Status Scale and the relapse rate. We explore the impact of the presence of the epsilon-2 allele on the progress of the disease. RESULTS: In patients under 21 years of age, we observed a higher frequency of the presence of the epsilon-4 allele (p = 0.057). Nevertheless, no association was found between any of the ApoE alleles and the indices of disease progression. CONCLUSIONS: Our results do not suggest any association between the presence of the ApoE epsilon-4 allele and the progression of disability in patients with MS in our sample.
