Plaque-induced gingivitis is the most common form of periodontal disease and can affect 100% of the population. Gingivitis prevalence in Latin American population is not well documented, therefore the aim of this study was to determine the prevalence and severity of plaque-induced gingivitis in adult populations of three Latin American cities.   Methods: This cross sectional multicenter study included 1650 participants, 550 from the Great Metropolitan Area of Costa Rica (GAM), 550 from Mexico City, Mexico (CDMX) and 550 from Bogota City, Colombia (BC). Subjects completed a questionnaire about their medical history and oral hygiene. Clinical assessment included recording of missing teeth, visible plaque index, calculus recording and gingival index (GI, Loe-Silness index).  Results: Average GI was 1.36. No statistical difference was found between GAM (1.45) and BC (1.48); however, GI in CDMX was significantly lower (1.16). Average gingival bleeding on probing was 43%. Total plaque index was 0.76 showing the highest accumulation at interproximal sites (p=0.0001). A positive correlation was found between plaque and gingivitis (r=0.59). Dental calculus was present in at least one of the 18 evaluated sites per subject with no statistical difference between cities. There was no statistical difference in GI between smokers, former smokers and non- smokers.  Conclusion: Gingivitis prevalence was 99.6%. Moderate Gingivitis was the predominant form, with no statistically significant difference between cities or gender. Dental plaque accumulation was the most important risk factor associated with the establishment of the disease.

The City

In the life of Latin American cities the rapid expansion of slum neighborhoods has emerged as a compelling problem. The inability of city authorities to provide adequate and inexpensive housing for rural-to-urban migrants, as well as for those economically poor persons born and raised in the city, has clashed with the tremendous growth of the population and its drive toward urbanization. The impoverished families must settle wherever they can. Scattered throughout Mexico City, for instance, on vacant lots adjoining factories or on the periphery of the metropolitan area are shack homes built of miscellaneous materials, known as jacales, or the rows of single-story concrete, brick, or adobe dwellings called vecindades. Beyond Mexico City, there are the villas miserias of Buenos Aires, the favelas on the rocky promontories of Rio de Janeiro, the barrios clandestinos of Bogotá, the barriadasmarginales of Lima, the ranchos of Caracas, and the callampas (mushrooms) of Santiago.

AbstractThe Brazilian National School Feeding Program (PNAE) seeks to meet student’s nutritional needs during the period they remain in school. This study aimed to determine the nutritional composition of meals provided in municipal day-care centres serving children of 7–11 months (group A) and 12–36 months (group B) of age and to compare observed values with the PNAE’s and dietary reference intakes’ (DRI) recommendations. This cross-sectional study was conducted in 4 day-care centres in the metropolitan area of Curitiba, Paraná, Brazil, between June and November 2013. Food samples of six daily meals were collected during 20 non-consecutive days, totalling 120 samples. For each meal, average served and consumed portions were submitted for laboratory analysis of moisture, ash, proteins, lipids, carbohydrates, dietary fibre, Na, Ca and Fe and compared with the PNAE’s and DRI’s values. No statistically significant difference was found between age groups (P=0·793) regarding portion sizes and nutritional composition. The same menu was offered to both groups in 95 % of the meals (n 114), although the groups’ nutritional needs were different. For group A, served meals met PNAE’s recommendations for energy, carbohydrates, proteins, Na and Ca content, and consumed portions provided 70 % of the nutritional needs for carbohydrates, proteins and Ca. For group B, served portions complied with the PNAE’s values for proteins, Na and Ca. Proteins and Na reached 70 % of the nutritional needs when consumed food was evaluated. School feeding in day-care centres partially meet PNAE’s guidelines and children’s nutritional requirements, contradicting the primary objective established by the national programme.

Most orthodontic patients struggle to maintain good oral hygiene during treatment. To determine oral hygiene habits and status of patients undergoing fixed orthodontic treatment at University of Pretoria, Oral and Dental Hospital. A cross-sectional descriptive study. A modified, validated, self-administered questionnaire was used, and clinical examinations were conducted using Orthodontic Plaque Index, Gingival index, and Bleeding index. The questionnaire sought to determine knowledge and practice patterns. Data analysis included frequencies and correlations using chi-square test, with a significance of p<0.05.Fifty patients participated with 34(68%) being female with ages from 10 to 28 and a mean of 18,5. Seventy percent avoided sticky foodstuff, 74% used mouthwash, 56% flossed daily and 84% brushed twice daily. However, 82% consumed sugar containing drinks. Clinical exam revealed an Orthodontic Plaque Index mean of 2.6, Gingival Index mean of 0.1 while the Bleeding Index was 13.3 and 90% had normal gingiva. There was a significant difference in Gingival Index score between patients at age category 10-19 and 18-24 (p< 0.05). This study revealed a satisfactory oral hygiene status among patients at the institution with the majority of patients maintaining good oral hygiene practices. However, 82% consumed sugar sweetened beverages.

Discourse markers of attention focus (enfocadores de alteridad in Spanish) frequently serve the purposes of drawing the hearer’s attention to what the speaker is saying, either to establish or maintain contact between the two interlocutors.  The current study aims to determine whether the choice of appellative marker is socially or grammatically motivated.  Using sociolinguistic corpora from two major Latin American cities, the study will analyze the variation among the markers.  More specifically, are there extenuating factors that influence whether a speaker elects to use mira, fíjate or oye to focus the attention of the hearer?  The study finds that the choice between markers in San Juan and Mexico City is conditioned by different markers in each locale and, additionally, hints that the style of discourse may have an effect on the prevalence of these markers in general.

Abstract Objectives The SARS-CoV-2 virus continues wreaking worldwide havoc on health and between March and August 2020, the first outbreak of COVID-19 hit Chile. The pregnant population is especially vulnerable to infection. Studies have been published that associate socioeconomic status, overcrowding, and poverty with a higher prevalence of SARS-CoV-2 infection. There are few studies about the development of this pandemic in Latin American countries so far. This study seeks to show the prevalence and sociodemographic and perinatal characteristics in pregnant women at the time of delivery, comparing both groups with positive and negative COVID-19 PCR results. Methods A prospective, cross-sectional study of pregnant women who delivered at the San Juan de Dios Hospital in Santiago between April 15, 2020 and June 15, 2020. Analysis of epidemiological, sociodemographic, obstetric, perinatal and sociodemographic data of patients with positive and negative COVID-19 PCR results. Results There were 701 patients included in the study. The prevalence of those with a positive COVID-19 PCR was 9.7% and 67.7% being asymptomatic. Pre-term delivery was significantly higher in the group of positive patients (23.5%) vs. negative patients (8.7%), which was not the same rate as with cesarean sections (C-sections). A 13.2% of patients required management of the pathology in the Critical Care Unit (CCU) and there were no cases of maternal or fetal deaths. We found no significant difference between both groups when analyzing socioeconomic variables, though we noted a trend of greater overcrowding among the group of patients with infection. Conclusions The majority of pregnant patients with SARS-CoV-2 infection are asymptomatic. COVID-19 increases the rate of premature births, but this rate is not same with C-sections. Sociodemographic conditions and overcrowding do not show a higher infection rate in a homogeneous population in relation to the economic, social and demographic level.

A Cross-sectional Study was carried out to determine the prevalence of gastrointestinal (G.I.)  helminths parasites in slaughtered cattle at Azare abattoir, Katagum Local Government Area, Bauchi State, North-Eastern Nigeria. One hundred and twenty faecal samples were examined using the floatation and sedimentation method. Out of the total samples tested, G.I. helminths infections were detected in 62samples tested, giving an overall prevalence of 51.6%. Class nematodes are the most diverse class (56.5%) and then followed by trematodes (35.5%), while cestodes are the least prevalent (8.1%). There was a statistically significant difference in P-value >0.05.  The sex revealed that males (52.6%) are more susceptible to G.I. helminths infection than females (50.0%) even though there is no statistical difference at P-value >0.05. However, the prevalence of G.I. helminths to age revealed a statistical difference at P-value >0.05, where the young have the highest prevalence of 59.5%.  The Red Bororo breeds had the highest prevalence of 75%, while the least was recorded in White Fulani and Sokoto Gudali, 40% each. There was a statistically significant difference at P-value >0.05. This study revealed that Fasciola spp (15%) is the most prevalent G.I. helminths parasites detected, followed by Oesophagostomum spp (11.7%); Haemonchus spp (9.2%); Strongyloides spp (8.3%), Schistosoma spp (3.3%); and Moniezia spp (1.67%). Our findings from the present study revealed a high prevalence of G.I. helminths species affecting cattle in Azare and Nigeria as a whole. Therefore, there is a great need for proper advocacy on the need for appropriate management, regular deworming practices, and improved cattle hygiene to boost animal production. This will help in curbing great lost to Nigeria's economy and the world in general.
