As a result, Cubans have developed a unique and robust offline system for distributing digital content through removable storage media like USB thumb drives and portable hard drives called El Paquete Semanal (The Weekly Package). In this paper, we describe and analyze the contents of El Paquete and how those contents vary over time and between distributors. We compare it to a lesspopular state sponsored alternative called La Mochila (The Backpack) and discuss their respective distribution systems. We also compare these offline content distribution systems to available online access points such as those in public WiFi parks,tourist hotels, and universities. Finally, we reflect on how this system, developed in the Cuban context, could be useful in other environments.

It was concluded that 90% of the patients aged 40-59, with less than 6 months of clinical course, had better results at the end of the study, so the treatment was effective.

Methods Forty-seven systemically healthy participants with stage III periodontitis were recruited. Following SRP, the participants were randomly assigned to one of three treatment modalities; (1) placebo (n = 15), (2) probiotics (n = 16) and (3) antibiotics-azithromycin (n = 16). The participants were monitored at baseline, 3, 6, 9 and 12 months after therapy. Probing pocket depth (PPD), bleeding on probing (BOP), clinical attachment loss (CAL) and plaque accumulation (PI) were evaluated. Results All 47 participants completed the study. At 12 months, all groups showed significant improvements of PPD and PI (p < 0.012) irrespective of the treatment modality and without significant differences between the groups. P...

Se tomaron muestras microbiológicas a 30 sujetos con periodontitis estadio II grado B, en sacos periodontales con una profundidad de sondaje > 4 mm. Se realizó la irrigación subgingival con 5 mL. de clorhexidina en el grupo test y con 5 mL. de agua destilada en el grupo control. 24 horas después del procedimiento se obtuvo una segunda muestra a comparar. Se detectó que la irrigación subgingival con clorhexidina al 0,12 % logra disminuir en forma estadísticamente significativa la microbiota anaeróbica total (p< 0,05).

However, no recent studies have been conducted on the prevalence of T. tenax in Chile. The aim of this study was to determine the presence of T. tenax in patients with periodontal disease, admitted to the Dental Clinic of the University of Antofagasta, Chile, through Polymerase Chain Reaction (PCR) amplification of the beta-tubulin gene. Methods: An observational, cross-sectional study was conducted on 50 patients diagnosed with periodontal disease, 20 of them with gingivitis and 30 with periodontitis. T. tenax was identified by PCR amplification of the beta-tubulin gene. Associations between the protozoan and periodontal disease or the presence of risk factors to establish T. tenax infection were determined using the chi-square test and binary logistic regression analysis. Results: T. tenax was present in 28 out of 50 (56%) of patients with periodontal disease, and was more prevalent when associated with periodontitis (21 out of 30; 70%) than dental plaque-induced gingivitis (7 out of 20; 35%). Non-statistically-significant associations were observed between the presence of T. tenax and age, gender, smoking habit or diabetes. Statistically significant associations were observed between the presence of T. tenax and periodontal disease, and between T. tenax and the Periodontal Screening and Recording (PSR) index. Conclusion: T. tenax showed a high presence in patients with progressive states of periodontal diseases. Consequently, T. tenax detection is strongly recommended in patients with periodontal disease diagnosis and with a PSR index greater than 3.

Forty-seven systemically healthy volunteers with chronic periodontitis were recruited and monitored clinically and microbiologically at baseline for 3, 6 and 9 months after therapy. Subgingival plaque samples were collected from four periodontal sites with clinical attachment level ≥1 mm, probing pocket depth ≥4 mm and bleeding on probing, one site in each quadrant. Samples were cultivated and processed using the PCR technique. Patients received nonsurgical therapy including scaling and root planing (SRP) and were randomly assigned to a probiotic (n=16), antibiotic (n = 16) or placebo (n = 15) group. L. r...

Sus principales factores e indicadores de riesgo son compartidos con las enfermedades crónicas no transmisibles (ECNT). Además, la presencia de enfermedad periodontal en un paciente con ECNT puede contribuir a su exacerbación y/o desarrollo, a través de diversos mecanismos patogénicos, y el tratamiento de la condición periodontal genera una reducción de la inflamación sistémica. Debido a lo anterior, las enfermedades periodontales deben considerarse como una ECNT, y se debe trabajar en la creación, desarrollo e implementación de medidas de promoción de la salud y de prevención de ellas y participar activamente de las propuestas ya emanadas desde aquellas ECNT que tienen como objetivo a los mismos indicadores/factores de riesgo de las enfermedades periodontales.
