Botulinum toxin type A has a good safety profile during the first months of use. However the occurrence of adverse events is more frequent among children with cerebral palsy than individuals with other conditions. Severe adverse events are potentially related with the use of botulinum toxin type A, but data are sparse and additional study is required to clarify the causal relation.

There are few social epidemiologic studies on chickenpox outbreaks, although previous findings suggested the important role of social determinants. This study describes the context of a large outbreak of chickenpox in the Cauca Valley region, Colombia (2003 to 2007), with an emphasis on macro-determinants. We explored the temporal trends in chickenpox incidence in 42 municipalities to identify the places with higher occurrences. We analyzed municipal characteristics (education quality, vaccination coverage, performance of health care services, violence-related immigration, and area size of planted sugar cane) through analyses based on set theory. Edwards-Venn diagrams were used to present the main findings. The results indicated that three municipalities had higher incidences and that poor quality education was the attribute most prone to a higher incidence. Potential use of set theory for exploratory outbreak analyses is discussed. It is a tool potentially useful to contrast units when only small sample sizes are available.
Objective. Polymerized-type I collagen (polymerized-collagen) is a downregulator of inflammation and a tissue regenerator. The aim was to evaluate the effect of intra-articular injections (IAIs) of polymerized-collagen among patients with symptomatic knee osteoarthritis (OA) in delaying or preventing joint replacement surgery. Patients and Methods. This was a cohort study of 309 patients with knee OA. Patients with mild-to-moderate disease were treated weekly with IAIs of 2 mL of polymerized-collagen for six weeks (n = 309). Follow-up was for 6–60 months. The primary endpoints included the following determinations: (1) therapeutic effect; (2) survival from total knee replacement surgery (TKR); (3) Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and pain (visual analogue scale, VAS). Clinical improvement was defined as a decrease in pain exceeding 20 mm on the VAS and the achievement of at least 20% improvement from baseline with respect to the WOMAC score. Radiographic analysis was performed at baseline and 60 months. The joint space width in the medial, lateral, and patellofemoral compartments was calculated. Results. Patients who received IAIs of polymerized-collagen had a statistically significant improvement in the primary criteria (p<0.05). Kaplan–Meier survival analysis of the therapeutic effect demonstrated 98.8% survival at 60 months with TKR as the endpoint. There was no significant reduction in joint space in any compartment based on the analyzed radiographs. No serious adverse events were recorded. Conclusion. Polymerized-collagen increased the time to TKR by at least 60 months, modifying the disease course, improving functional disability, and decreasing pain.
Background Social disadvantages that start during childhood and continue into the later stages in life may be linked to the presence of diabetes during adulthood. Objective . To analyze whether the presence of social disadvantages in childhood and in the present affects the presence of diabetes in older adults. Methods The present study was based on longitudinal data from the third and fourth Mexican Health and Aging Study (MHAS) waves (2012 and 2015). Data on diabetes diagnosis, past (e.g. “no shoes during childhood”) and present (e.g. self-perception of economic status) social disparities, and other covariables were analyzed. Results From 8,848 older adults, 21.5% ( n = 1903) were classified as prevalent cases (PG), 5.2% ( n = 459) as incident cases (IG) and 77.4% ( n = 6,486) were free of disease (NDG). The predictor variable “no shoes during childhood” was statistically significant in the model incident versus no diabetes group. Hypertension and body mass index (BMI) were the most relevant covariates as they were statistically significant in the three groups (PG, IG and NDG). Conclusions Not having shoes during childhood, an indicator of social disadvantages, is associated with the incidence and prevalence of diabetes in older adults. This suggests that social disadvantages can be a determinant for the presence of chronic diseases in adulthood.
Objetivos Describir las características epidemiológicas y sociodemográficas de los portadores asintomáticos reportadas en la literatura y revisar las estrategias utilizadas para el diagnóstico y control.Métodos Se realizó una revisión sistemática de la literatura. Se incluyeron todos los estudios publicados entre el 1.º de enero y el 26 de junio de 2020 realizados en humanos que informaron personas que permanecieron asintomáticas por COVID-19. Se adaptaron descriptores a las interfaces de ocho bases de datos bibliográficas: PubMed, Ovid, SciELO, Ebsco, Scopus, LILACS, Epistemonikos y Embase.Resultados Aproximadamente el 45% de los artículos reportaron población adulta, trece estudios informaron población mixta (adultos y pediátricos). Se identificaron 3525 personas asintomáticas, con un promedio de 37,1 años [0,5-82 años]. Si bien no se reportó efectividad de medidas de control y prevención, la identificación, aislamiento y seguimiento de los contactos se destaca como un potencial mecanismo efectivo para prevenir la transmisión.Conclusiones El uso de esta información podría ser relevante para orientar las políticas de salud pública basadas en la evidencia y la protección de las poblaciones y la mejora de la atención médica que contribuya a detener esta pandemia.
Purpose – The purpose of this paper is to determine which socioecological factors encourage rural women to participate in mammographies rather than avoiding taking the test. Design/methodology/approach – The study mainly uses data from the 2007 Rural Households Evaluation Survey (ENCEL-2007). These crossover data are analyzed using the framework proposed in the Spatial-Interaction Model of Mammography Use (SIMMU), through a three-level logistic regression model to examine the likelihood that a woman will choose to participate in a mammography. Findings – At the woman-household level, the completion of the Pap smear and the asset index is the strongest determinant of mammography participation. Obtaining preventive medicine services or being enrolled in the Popular Insurance System prevent women from undergoing screening. At the interpersonal level, the probability of screening use decreases with lower social coverage. At the intermediate level, availability of health centers is negatively related to the use of screening. Research limitations/implications – The study fails to take into account the fact that women’s propensity to have a mammography may vary over time relatively to life changes. Moreover, findings were restricted to women ages from 40 to 49 and limited due to the lack of published data or data quality issues. Practical implications – The results of this research can give health planners, policymakers and social marketers a platform for how to approach social change and promote the cancer screening health behavior through the marketing mix (price, place, promotion and product) in the design of their programs. Originality/value – In addition to be informative and persuasive with people to change their behavior, this paper also seeks to provide a direction for using commercial marketing tools through social marketing to “sell” the health behavior. Due to target population variation, this paper addresses the health behavior change strategy by audience segmentation, regarded as essential to successful health communication campaigns.
