    Full Text Available Numerous studies have quantified antibiotic resistance genes (ARG in rivers and streams around the world, and significant relationships have been shown that relate different pollutant outputs and increased local ARG levels. However, most studies have not considered ambient flow conditions, which can vary dramatically especially in tropical countries. Here, ARG were quantified in water-column and sediment samples during the dry-and wet-seasons to assess how seasonal and other factors influence ARG transport down the Almendares River (Havana, Cuba. Eight locations were sampled and stream flow estimated during both seasons; qPCR was used to quantify four tetracycline, two erythromycin, and three beta-lactam resistance genes. ARG concentrations were higher in wet-season versus dry-season samples, which combined with higher flows, indicated greater ARG transport downstream during the wet season. Water-column ARG levels were more spatially variable in the dry-season than the wet-season, with the proximity of waste outfalls strongly influencing local ARG levels. Results confirm that dry-season sampling provides a useful picture of the impact of individual waste inputs on local stream ARG levels, whereas, the majority of ARGs in this tropical river were transported downstream during the wet season, possibly due to re-entrainment of ARG from sediments.

    Considerable debate exists over the primary cause of increased antibiotic resistance (AR) worldwide. Evidence suggests increasing AR results from overuse of antibiotics in medicine and therapeutic and nontherapeutic applications in agriculture. However, pollution also can influence environmental AR, particularly associated with heavy metal, pharmaceutical, and other waste releases, although the relative scale of the “pollution” contribution is poorly defined, which restricts targeted mitigation efforts. The question is “where to study and quantify AR from pollution versus other causes to best understand the pollution effect”. One useful site is Cuba because industrial pollution broadly exists; antibiotics are used sparingly in medicine and agriculture; and multiresistant bacterial infections are increasing in clinical settings without explanation. Within this context, we quantified 13 antibiotic resistance genes (ARG; indicators of AR potential), 6 heavy metals, 3 antibiotics, and 17 other organic pollutants at 8 locations along the Almendares River in western Havana at sites bracketing known waste discharge points, including a large solid waste landfill and various pharmaceutical factories. Significant correlations (p < 0.05) were found between sediment ARG levels, especially for tetracyclines and β-lactams (e.g., tet(M), tet(O), tet(Q), tet(W), blaOXA), and sediment Cu and water column ampicillin levels in the river. Further, sediment ARG levels increased by up to 3 orders of magnitude downstream of the pharmaceutical factories and were highest where human population densities also were high. Although explicit links are not shown, results suggest that pollution has increased background AR levels in a setting where other causes of AR are less prevalent. PMID:21133405

  3. Graham Greene and Cuba: Our man in Havana?

    Directory of Open Access Journals (Sweden)

    2008-12-01

    Full Text Available [First paragraph] Graham Greene’s novel Our Man in Havana was published on October 6, 1958. Seven days later Greene arrived in Havana with Carol Reed to arrange for the filming of the script of the novel, on which they had both been working. Meanwhile, after his defeat of the summer offensive mounted by the Cuban dictator, Fulgencio Batista, in the mountains of eastern Cuba, just south of Bayamo, Fidel Castro had recently taken the military initiative: the day after Greene and Reed’s arrival on the island, Che Guevara reached Las Villas, moving westwards towards Havana. Six weeks later, on January 1, 1959, after Batista had fled the island, Castro and his Cuban Revolution took power. In April 1959 Greene and Reed were back in Havana with a film crew to film Our Man in Havana. The film was released in January 1960. A note at the beginning of the film says that it is “set before the recent revolution.” In terms of timing, Our Man in Havana could therefore hardly be more closely associated with the triumph of the Cuban Revolution. But is that association merely accidental, or does it involve any deeper implications? On the fiftieth anniversary of novel, film, and Revolution, that seems a question worth investigating, not with a view to turning Our Man in Havana into a serious political novel, but rather to exploring the complexities of the genre of comedy thriller and to bringing back into view some of the local contexts which might be less visible now than they were when the novel was published and the film released.

    The possibility to use the Eichhornia crassipes plant in the estimation of heavy metal levels in the Almendares river were evaluated in this paper. Concentration of Cd, Pb, Zn, Cu, Co, Cr and Ni in macrophyte Eichhornia crassipes (Water Jacint) were evaluated at 15 stations during the dry season of 2003 and 2004. In Eichhornia crassipes roots and in the bioavailable fraction of the sediments followed the some spatial trend, showing elevated metal concentration's at the some stations. Highly significant correlation were found for these elements in Eichhornia crassipes roots and in the organic fraction of the sediments, which means that the concentrations of these elements in Eichhornia crassipes are indicative of the bioavailable concentrations in sediments. Three main sources of heavy metal pollution were identified in the basin due to the high concentration of most of the studied metals in the sampling stations, the secondary smelter Antillana de Acero, an important provincial landfill in the street 100 and the Mordazo tributary river. The obtained results show that Eichhornia crassipes could be an interesting monitor of the heavy metal pollution in Almendares River

    Women are being diagnosed with HIV infection in increasing numbers, and now account for 50% of cases worldwide. In Cuba, HIV is more frequent in men, but in recent years, a growing number of women have been diagnosed. Describe patterns of HIV among women in Havana, Cuba, 1986-2011. Descriptive study of women with HIV aged >14 years, residents of Havana, Cuba, who were diagnosed with HIV from 1 January 1986 through 31 December 2011. Information was obtained from the limited-access HIV/AIDS database of Cuba's Ministry of Public Health. Data were studied from all reported cases, a total of 1274 women. Variables selected were age at diagnosis, education, municipality of residence, screening group, year of HIV diagnosis, late presentation, AIDS-defining condition, year of diagnosis as AIDS case, vital status at the end of 2011, and year of death (if applicable). Incidence of HIV and AIDS, cumulative incidence by municipality of residence, and case fatality rates were calculated. Those aged 20-29 years were most affected by HIV. Almost half (46.7%) the women had completed middle school, and a further 35.4% had completed high school or middle-level technical studies. HIV incidence began to increase more steeply starting in 1998, as did AIDS incidence by year of diagnosis, though to a lesser extent. Central Havana and Old Havana municipalities had the highest cumulative incidence. Late presentation was seen in 7.4% of cases; mean age of those diagnosed late was 38.9 years. Wasting syndrome and Pneumocystis jirovecii pneumonia were the most frequent AIDS-defining conditions. Case fatality rates started to decline in 1998. HIV infection in women is occurring in a predominantly young, relatively well-educated population. Increasing rates of HIV and AIDS in the past decade are a warning sign of the possible expansion of HIV infection in women, even though mortality is declining.

    From late 2016 through August 2017, US government personnel serving on diplomatic assignment in Havana, Cuba, reported neurological symptoms associated with exposure to auditory and sensory phenomena. To describe the neurological manifestations that followed exposure to an unknown energy source associated with auditory and sensory phenomena. Preliminary results from a retrospective case series of US government personnel in Havana, Cuba. Following reported exposure to auditory and sensory phenomena in their homes or hotel rooms, the individuals reported a similar constellation of neurological symptoms resembling brain injury. These individuals were referred to an academic brain injury center for multidisciplinary evaluation and treatment. Report of experiencing audible and sensory phenomena emanating from a distinct direction (directional phenomena) associated with an undetermined source, while serving on US government assignments in Havana, Cuba, since 2016. Descriptions of the exposures and symptoms were obtained from medical record review of multidisciplinary clinical interviews and examinations. Additional objective assessments included clinical tests of vestibular (dynamic and static balance, vestibulo-ocular reflex testing, caloric testing), oculomotor (measurement of convergence, saccadic, and smooth pursuit eye movements), cognitive (comprehensive neuropsychological battery), and audiometric (pure tone and speech audiometry) functioning. Neuroimaging was also obtained. Of 24 individuals with suspected exposure identified by the US Department of State, 21 completed multidisciplinary evaluation an average of 203 days after exposure. Persistent symptoms (>3 months after exposure) were reported by these individuals including cognitive (n = 17, 81%), balance (n = 15, 71%), visual (n = 18, 86%), and auditory (n = 15, 68%) dysfunction, sleep impairment (n = 18, 86%), and headaches (n = 16, 76%).

    The aim of the study was to diagnose infections with rotavirus and other enteric pathogens in children under five years old with acute gastroenteritis and to identify the most common epidemiological and clinical characteristics of these pathogens. The study was conducted using 110 stool samples from the same number of children under five years old who were inpatients at three paediatric hospitals in Havana, Cuba, between October and December 2011. The samples were tested for rotavirus and other enteric pathogens using traditional and molecular microbiological methods. Pathogens were detected in 85 (77.3 %) of the children. Rotavirus was the most commonly found, appearing in 54.5 % of the children, followed by bacteria (29 %) and parasites (10.9 %). Other viral pathogens detected included adenovirus (6.4 %) and astrovirus (3.6 %). In rotavirus-positives cases, at least one other pathogen was detected, usually a bacterium (26.6 %). More than three episodes of watery diarrhea in 24 hours were observed in 78.3 % of the cases. Dehydration was found in 30 (50 %) rotavirus-positive children, of whom seven (11.6 %) were transferred to an intensive care unit due to complications of metabolic acidosis. Rotavirus was most commonly observed among children under 12 months old (65 %). The highest incidence of infection occurred in children who were under the care of a relative at home (78.3 %), had not been breastfed (65 %), or had been breastfed for less than six months (28.3 %). The genotype combinations most frequently found were G9P8 (28.3 %) and G1P8 (10 %). This study demonstrates the presence of rotavirus and other enteric pathogens as causes of gastroenteritis in hospitalized infants and young children in Cuba.

    To determine the proportion of 14-year-old schoolchildren in the city of Havana, Cuba, with a positive tuberculin skin test, as an indicator of the prevalence of tuberculosis infection among them. Using single-stage cluster sampling, 1 936 Mantoux (tuberculin) tests were carried out with ninth-grade students (cohort born in 1985) during the 1999- 2000 school year in 20 basic high schools randomly selected in Havana. The tests were performed according to the standard technique recommended by the World Health Organization, and they were read after 72 hours. The percentage of skin tests that were positive and the average diameter of the indurations were calculated for the cohort overall and for the two genders. The means and the percentages were compared using the chi-square test, with 95% confidence intervals. The computer software used was Epi Info version 6.0. Of the tests read, 96% of them were negative (0-4 mm), 2.5% were doubtful (5-9 mm), and 1.5% were positive (>/=10 mm). The percentage of reactivity was 0.1% when a cutoff value of 15 mm was used. The mean diameter of the indurations was 0.41 mm. No statistically significant difference was found between the genders. In this study the proportion of schoolchildren with tuberculin reactivity, using an induration-diameter cutoff point of 10 mm, was very low (1.5%), and it was much lower (0.1%) when a cutoff point of 15 mm was used. The skin reactions with an induration diameter of >/=10 mm could be the expression of a natural infection if one takes into account the low frequency of bacillary tuberculosis in Cuba and that there is an inverse relationship between the time elapsed from the BCG vaccination and the intensity of the response to tuberculin. Therefore, that would mean that in this case (l)the point (.)prevalence of tuberculosis infection in this group of schoolchildren wou d be 1.5% ResumenObjetivos.

    Full Text Available The combination of molecular and conventional epidemiological methods has improved the knowledge about the transmission of tuberculosis in urban populations. To examine transmission of tuberculosis in Havana, Cuba, with DNA fingerprinting, we studied 51 out of 92 Mycobacterium tuberculosis strains isolated from tuberculosis patients who resided in Havana and whose infection was culture-confirmed in the period from September 1997 to March 1998. Isolates from 28 patients (55% had unique IS6110 restriction fragment length polymorphism (RFLP patterns, while isolates from 23 others (45% had identical patterns and belonged to 7 clusters. Three clusters consisting of six, five and two cases were each related to small outbreaks that occurred in a closed setting. Three other clustered cases were linked to a large outbreak that occurred in another institution. Younger patients were more correlated to clustering than older ones. The finding that 45% of the isolates had clustered RFLP patterns suggests that recent transmission is a key factor in the tuberculosis cases in Havana. The IS6110 RFLP typing made it possible to define the occurrence of outbreaks in two closed institutions.

    Concentrations of nickel (Ni), copper (Cu), zinc (Zn) and lead (Pb) in beach and dune sands from thirteen Havana (Cuba) resorts were estimated by X-ray fluorescence analysis. Determined mean metal contents (in mg·kg(-1)) in beach sand samples were 28±12 for Ni, 35±12 for Cu, 31±11 for Zn and 6.0±1.8 for Pb, while for dune sands were 30±15, 38±22, 37±15 and 6.8±2.9, respectively. Metal-to-iron normalization shows moderately severe and severe enrichment by Cu. The comparison with sediment quality guidelines shows that dune sands from various resorts must be considered as heavily polluted by Cu and Ni. Almost in every resort, the Ni and Cu contents exceed their corresponding TEL values and, in some resorts, the Ni PEL value. The comparison with a Havana topsoil study indicates the possible Ni and Cu natural origin. Copyright © 2015 Elsevier Ltd. All rights reserved.

  17. Use of the renewable wind and photovoltaic sources, for the recharge of a fleet of electric taxis in Havana, Cuba

    Electrification of the transportation sector seems to be one of the alternatives in terms of restriction of pollutant from that sector. However, it is necessary to study the GHG (Green House Gas) emissions from Generation Power Plants (EGPP) because could be more or less the same of that from the vehicles. Furthermore, Centralized GPP supply would result in distribution losses, bigger fuel consumption and more pollution. Thus, EVs development should be considered as a sustainable solution if powered by electricity systems with considerable share of Renewable Energy Sources (RES). In this paper, the study of the recharge of an EV taxi fleet during night, using photovoltaic and wind mills RES in Havana, Cuba, is analyzed. This work is aiming to find a feasible operational synergy between cited intermittent RES electricity generation and EVs taxi fleet recharge. (author)

    Concentrations of Cr, Co, Ni, Cu, Zn, Pb and Fe in the top-soils (0-10 cm) of Havana city urbanized and un-urbanized areas were measured by X-ray fluorescence analysis. The mean Cr, Co, Ni, Cu, Zn and Pb contents in the urban topsoil samples from Havana City (151 ± 90, 13.9 ± 4.1, 66 ± 26, 101 ± 51, 240 ± 132 and 101 ± 61 mg.kg -1 , respectively) were compared with mean concentrations for other cities around the world. The results revealed higher concentrations of heavy metals in topsoil samples from industrial sites. Lowest heavy metal contents were determined in the un-urbanized areas. The comparison with Dutch soil quality guidelines showed a slightly contamination with Cr, Co, Ni Cu and Zn in all studied sites and with Pb in industrial soils. On the other hand, the metal-to-iron normalisation using Earth crust contents as background showed that soils from urbanized areas in Havana city (industrial sites, parks and school grounds) are moderately enriched by zinc, moderately to severe enriched (city parks and school grounds) and severe enriched (industrial sites) by lead.

    The low 137 Cs activity observed in marine sediments of tropical regions often precludes its use as chronostratigraphic marker. Here we present a study on the use of Pu and Am radioisotopes as alternative markers to constrain the 210 Pb ages in a sediment core of the Havana Bay (Cuba). Mean activity ratios of 238 Pu/ 239,240 Pu, 241 Am/ 239,240 Pu and 241 Pu/ 239 , 240 Pu indicated that the nuclear weapon tests (NWT) fallout is the main source of the anthropogenic radionuclides. While the inventory of 137 Cs in the sediments is lower than the expected fallout inventory, 239,240 Pu accumulates in the sediments with inventories higher than the expected fallout inventory. The high fluxes of 239,240 Pu are nevertheless corroborated here through use of 210 Pb, and confirm that focusing of solid particles is of great importance in the investigated site. 239,240 Pu showed to be a useful time tracer in marine sites where the 137 Cs signal is very low.

    Given the geographic, demographic, and historical importance of Cuba vis-a-vis the dissemination of language and culture throughout the Hispanic Caribbean, one would naturally anticipate a larger corpus of scientifically-noteworthy linguistic publications on Cuban Spanish, which is far from the actual case. Moreover, the gemination of an onset positionally subsequent to the deletion of a syllable-final liquid (generally termed liquid gemination in the literature) has been repeatedly claimed yet remarkably unsubstantiated as a pervasive characteristic of Cuban Spanish, particularly of the western dialect region (cf. Alfaraz (2000, 2007, 2008), Casanellas and Alamo (1985), Choy Lopez (1985, 1988, 1989), Costa Sanchez (1987), Darias Concepcion (2001, 2005), Dohotaru (2002, 2007), Figueroa Esteva and Dohotaru (1994), Garcia Perez (2006), Garcia Riveron (1991), Haden and Matluck (1973, 1974, 1977), Isbǎsescu (1965, 1968), Lamb (1968), Levina (1970), Montero Bernal (1990, 2002, 2007a, b), Ringer Uber (1986), Ruiz Hernandez (1978), Sosa (1974), Terrell (1976), Trista and Valdes (1978), Valdes Acosta (1980), and Vera Riveron (2000)). As a result, in the interest of supplementing all antecedent work concerning the allophony of final liquids as well as affording a more descriptively-precise account of the allophony of word-internal, post-nuclear /l/ and /[Special character omitted]/ in Cuban Spanish in addition to expressly addressing the need for empirical data-collection and analysis processes, the present investigation was specifically designed and implemented to acoustically investigate the phenomenon of gemination as it is purported to occur in the Spanish of the region of Havana, Cuba: more specifically, (1) to acoustically examine the qualitative and quantitative patternings of post-nuclear /l/ and /[Special character omitted]/ within the word; and (2) to statistically evaluate the relationship between gemination and eight independent variables: gender, age group

    As a part of a geochemical study, aliphatic and aromatic hydrocarbons were determined in surficial sediments, from a Cuban coastal zone located in the Northeastern Havana Littoral. Sediment samples were collected at 15 sites in this area, and then extracted and analyzed by gas chromatography with flame ionization and mass spectrometry detectors. Total concentration of both, aliphatic (AH) and aromatic (ArH) hydrocarbons, varied from 2.4 {+-} 0.2 to 105.1 {+-} 5.9 {mu}g/g (dry weight) and from 1.1 {+-} 0.2 to 38.4 {+-} 7.6 {mu}g/g (dry weight), respectively. The chromatography profile of AH was dominated by an unresolved complex mixture (UCM), and the presence of isoprenoid hydrocarbons, steranes and hopanes, indicated petroleum - related hydrocarbon inputs. The predominant concentration of phytoplanktonic molecular markers (pristane and nC17) in collected sediments, revealed the marine productivity in this sites. The anthropogenic contribution detected showed the impact of the petroleum exploration along this coastal area.

    Background The 55th World Health Assembly declared dengue prevention and control a priority and urged Member States to develop sustainable intersectoral strategies to this end. To provide evidence for the reorientation of the dengue prevention policy in Cuba, we launched an intervention study to document the effectiveness of a local-level intersectoral approach. We used a quasi-experimental design. Social scientists introduced participatory methods to facilitate dialogue in the biweekly meetings of the intersectoral Health Council of the intervention area. This council subsequently developed an intersectoral plan for dengue prevention, of which the core objective was to design and implement activities for communication and social mobilization. In the control area, routine dengue control activities continued without additional input. Knowledge, attitudes and perceptions of dengue, and entomological indices were compared inside and between the areas before and after the 1-year intervention period. In the intervention area the Health Council elaborated an intersectoral plan for dengue prevention focused on source reduction. The Aedes aegypti control methods consisted in eliminating useless containers in the houses and surroundings, covering tanks, and cleaning public and inhabited areas. It was implemented through communication and social mobilization. The Health Council in the control area occasionally discussed dengue issues but did not develop a coordinated action plan. Good knowledge about breeding sites and disease symptoms increased significantly (by 49.7% and 17.1% respectively) in the intervention area as well as the proportion of respondents eliminating containers in and around their houses (by 44%). No changes were observed in the control area. The House Index in the intervention area was 3.72% at baseline and decreased to 0.61% after 1 year. In the control area it remained stable throughout the study period (1.31% and 1.65% respectively). The introduction

    Epiphytic lichens, collected from 119 sampling sites grown over "Roistonea Royal Palm" trees, were used to assess the spatial distribution pattern of lead (Pb) and identify possible pollution sources in Havana (Cuba). Lead concentrations in lichens and topsoils were determined by flame atomic absorption spectrophotometry and inductively coupled plasma (ICP) atomic emission spectrometry, respectively, while Pb in crude oils and gasoline samples were measured by ICP-time of flight mass spectrometry (ICP-ToF-MS). Lead isotopic ratios measurements for lichens, soils, and crude oils were obtained by ICP-ToF-MS. We found that enrichment factors (EF) reflected a moderate contamination for 71% of the samples (EF > 10). The 206 Pb/ 207 Pb ratio values for lichens ranged from 1.17 to 1.20 and were a mixture of natural radiogenic and industrial activities (e.g., crude oils and fire plants). The low concentration of Pb found in gasoline (leaded gasoline is no longer used in Cuba.

    Highlights: ► Past metal pollution in the heavy polluted coastal ecosystem of Havana Bay. ► Effectiveness of pollution-reduction strategies. ► Dated environmental archives to reconstruct sedimentation and pollution trends. ► Impact of severe climatic events on sedimentation. - Abstract: Since 1998 the highly polluted Havana Bay ecosystem has been the subject of a mitigation program. In order to determine whether pollution-reduction strategies were effective, we have evaluated the historical trends of pollution recorded in sediments of the Bay. A sediment core was dated radiometrically using natural and artificial fallout radionuclides. An irregularity in the 210 Pb record was caused by an episode of accelerated sedimentation. This episode was dated to occur in 1982, a year coincident with the heaviest rains reported in Havana over the XX century. Peaks of mass accumulation rates (MAR) were associated with hurricanes and intensive rains. In the past 60 years, these maxima are related to strong El Niño periods, which are known to increase rainfall in the north Caribbean region. We observed a steady increase of pollution (mainly Pb, Zn, Sn, and Hg) since the beginning of the century to the mid 90s, with enrichment factors as high as 6. MAR and pollution decreased rapidly after the mid 90s, although some trace metal levels remain high. This reduction was due to the integrated coastal zone management program introduced in the late 90s, which dismissed catchment erosion and pollution.

    In this paper we report levels of Cu, Pb, Cd and Zn in soils and vegetables grown in a highly urbanized area of La Havana city. We studied 17 farms dedicated to urban agriculture in an area of two kilometers around the landfill -Calle 100- during 2006 and 2007. For the study, samples of the soil and all the vegetables ready to harvest were taken from the farms. The heavy metals Cu, Zn, Pb and Cd were analyzed by atomic absorption spectrophotometry. The levels of heavy metals in agricultural soils varied in the following ranges: Cd(0.24-2.1 mg/kg), Cu(38.4-81.3 mg/kg), Pb(18.1-138.5 mg/kg) and Zn(44.1-294.7 mg/kg). For Zn and Pb, some farm soils (35 and 52% respectively) exceeded the ranges in which these metals are found in Cuban agricultural soils. For Pb, 23% of the soils exceeded levels considered phyto toxic and limits in some international standards. The 12.5% of the samples of vegetables collected exceeded the maximum permissible levels of this pollutant in food for human consumption set by Cuban and international standards. The results indicate the need for strict crop monitoring in the area. (Author)

    Cuba's population characteristics, geography, history, government, political conditions, and foreign relations were briefly described. Cuba, the largest island in the East Indies, has a tropical climate and is made up of a large area of rolling plains and a smaller mountainous region. Cuba's current population of 9.946 million (1983) is 70% urban and 30% rural. The annual population growth rate is 1.1%. The literacy rate among those aged 10-49 years is 96%, and school is compulsory for 6 years. The infant mortality rate is 21/1000 live births, and life expectancy is 74.7 years. 47% of the work force is engaged in industry and commerce, 28% in services and government, and 25% in agriculture. Since the revolution, Cuba has had a centrally planned, nonmarket economy. Large state enterprises run all segments of the economy, and economic policy is formulated by a central planning board. Farmers are allowed to privately market some of their produce. The government provide a wide range of social services. Most of the services are free, but some entail a minimal fee. Cuba's economy is depressed and overly dependent on the production of sugar. Since the revolution, Cuba's sugar production has increased by only 1.1% annually. In addition to sugar production, the country is engaged in some food processing and other light forms of industry. Cuba has a large reserve of nickle. Cuba's economic indicators are calculated differently than those used in market countries and are not comparable to those used in market countries. In 1983, disposable national income was US$15.8 billion, and per capita income was US$2,590. Cuba's imports exceed her exports. In 1983 exports totalled US$6.5 billion and imports amounted to US$7.2 billion. Cuba's foreign debt is increasing annually, and Cuba is highly dependent on economic assistance from Russia. Between 1961-83, the USSR provided Cuba with US$30 billion in economic aid and US$10 billion in military aid. The country's serious economic

    Aim: With the purpose to measure the Total Energy Expenditure (TEE) and to validate the Cuban Dietary Energy Allowance for elderly subjects, energy expenditure was assessed by the doubly labeled water technique in 11 women aged 65.9 ± 2.8 y with a mean BMI of 21.4 ± 4.2 kg/m2 during 14 days under free-living conditions in their own environment in Havana City. Materials and Methods: After taking a basal urine sample, the women received an oral dose of 2.5 g H218O (10%) and 0.12 g 2H2O (99.8%) body weight and samples of saliva and urine were collected 14 days after. Resting Metabolic Rate (RMR) was estimated by the Schofield equations proposed by the 1985 FAO/WHO/UNU Expert Committee Report and energy intake was measured by trained dietitians using the 3-day weighed dietary record. A mean value of the food quotient of 0.85 was used for the calculations of the CO2 production by the isotopic method. Results: In spite of the expected variability, the differences between TEE measured by the isotopic method (7.57 MJ/d) and estimated according to FAO/WHO/UNU, 1985 (7.24 MJ/d) were not significant (0.625). The recommended dietary allowance for energy valid for Cuban elderly subjects (7.66 MJ/d) was only slight over the value of the measured TEE. The value of energy expenditure measured in free-living elderly women from Havana City was in the range of acceptable values (6-8 MJ/d) for this group of age. Conclusions: The total energy expenditure of elderly women from Havana City was lower than reported values for women living in developed countries but coincident with those of women of the developing world. The differences between dietary energy intake and TEE measured by the isotopic method were around 27% and coincident with previous reports in elderly people. The Cuban allowance for dietary energy for elderly women was enough for covering their energy requirements

    The Artemisa-Quivican Basin is located in the southern sector of the province of Havana, Cuba. This basin contains the most important aquifer of Havana province. It has a length of nearly 120 km and is 25 km in width. Recharge depends on the precipitation regime and rain infiltrates in a considerable proportion due to the intense development of karstic features. This aquifer is used for water supply to population, industry, and irrigation and is affected by over-exploitation and risk of contamination by saline sea intrusion. The main objective of this study is the isotope and chemical characterization of the aquifer and the delimitation of the area influenced by saline intrusion. Groundwater and river water are of the calcium bicarbonate type except those with evidence of mixture with saline water. Groundwater exhibits a variable proportion of mixture with seawater, indicating the presence of the saline intrusion. (author)

Strategically situated in the Antilles, the city always played the role of a gate to the Spanish colonies in the Americas. After the Cuban independence (1898, the Caribbean city fell under the influence of the crescent power of the United States. At the turn of the XXth century, the city which during the colonial times based its economy on trade of commodities from the mainland like tobacco or sugar, turned to be funded mainly by North American tourism. The city attracted legal investment and mafia groups equally. Disparity and growing authoritarianism led to the well known Cuban Revolution and with its socialist reforms, the city froze in time. With the Soviet collapse, the government searched for economic alternatives facing a strong U.S. embargo. Tourism appeared once more as an important source of income. Yet, this new transition raises questions like: how is this reorientation going to change spatially Havana? Or, how are deeper changes in the socialist regime going to affect the heritage and identity of the city?

    Full Text Available The work was developed in the Los Amaros, the Santa Cruz river, Artemisa, Cuba. The objective was to evaluate how it influences the expansion of the agricultural frontier on riparian vegetation where the semi-deciduous mesophytic forest (BsdMe predominates. A floristic characterization was performed, identifying the effects of disturbances on the structure and composition of these forests and their relation to human disturbance. A semi-structured interview was applied to all landowners in the study area. Species richness, dominance, basal area, total number of individuals, width of the strip covered by trees and shrubs, and area without vegetation on both banks of the river, respectively were considered as variables. There are differences in the structure and patterns of diversity of the studied forest, as a result of disturbances, with the consequent reduction of species; also anthropogenic disturbances, are the main factors that explain changes in the structure of these forests. They are identified as major species: Cupania macrophylla A. Rich., Roystonea regia HBK O. F. Cook., Guarea guidonia L. Sleumer and Trichilia hirta  L. It is proposed to deepen the effect of the expansion of agriculture into other sectors of the river in interaction with local communities.

    The city of Havana, the political, administrative and cultural centre of Cuba, is also the centre of many of the economic activities of the nation: industries, services, scientific research and tourism. All of these activities contribute to the generation of municipal solid waste (MSW), which also impact other Cuban cities. Inadequate handling of waste and the lack of appropriate and efficient solutions for its final disposal and treatment increase the risk and possibility of contamination. The main difficulty in the development of a system of management of MSW lies in the lack of knowledge of the chemical composition of the waste that is generated in the country as a whole, and especially in Havana, where solid waste management decisions are made. The present study characterizes MSW in Havana city during 2004. The Calle 100, Guanabacoa and Ocho Vías landfills were selected for physical-chemical characterization of MSW, as they are the three biggest landfills in the city. A total of 16 indicators were measured, and weather conditions were recorded. As a result, the necessary information regarding the physical-chemical composition of the MSW became available for the first time in Cuba. The information is essential for making decisions regarding the management of waste and constitutes a valuable contribution to the Study on Integrated Management Plan of MSW in Havana.

    A few years ago, I was privileged to visit the Republic of Cuba as a summer vacation. Officially, this Spanish island is the largest island in the Caribbean, with more than 12 million people. It is only second as being most populous after Hispaniola with its people, culture and customs. Havana is the capital and Cuba's largest city. The United States lies to the immediate north only about 95 miles away, and the Bahamas and Mexico to the west, the Cayman Islands and Jamaica are on the southern end, and Haiti and the Dominion Republic are in the southeastern area. The history of this island is truly amazing. I was able to vist a hospital, and ride public transportation (bus). The trip was made at the time when Cuba was not open to travelers coming direct from the United States. I traveled to Montreal, Canada to board Cabana Arlines to Havana, Cuba.

    In this paper we report levels of Cu, Pb, Cd and Zn in soils and vegetables grown in a highly urbanized area of La Havana city. We studied 17 farms dedicated to urban agriculture in an area of two kilometers around the landfill -Calle 100- during 2006 and 2007. For the study, samples of the soil and all the vegetables ready to harvest were taken from the farms. The heavy metals Cu, Zn, Pb and Cd were analyzed by atomic absorption spectrophotometry. The levels of heavy metals in agricultural soils varied in the following ranges: Cd(0.24-2.1 mg/kg), Cu(38.4-81.3 mg/kg), Pb(18.1-138.5 mg/kg) and Zn(44.1-294.7 mg/kg). For Zn and Pb, some farm soils (35 and 52% respectively) exceeded the ranges in which these metals are found in Cuban agricultural soils. For Pb, 23% of the soils exceeded levels considered phyto toxic and limits in some international standards. The 12.5% of the samples of vegetables collected exceeded the maximum permissible levels of this pollutant in food for human consumption set by Cuban and international standards. The results indicate the need for strict crop monitoring in the area. (Author)

    Dr Yamila de Armas has occupied an array of posts since finishing her residency in family medicine in her home province of Cienfuegos in 1992. She has served as a family doctor; polyclinic, municipal and provincial health director; medical school dean; and twice vice minister of public health. But few would doubt her toughest job is the one she has now: deputy director of the Havana City Provincial Health Department, in charge of medical services for the 2.2 million people living in Cuba's complex, sprawling capital. It was here in 2002-2003 that the program was launched to repair, refurbish and expand the country's nearly 500 community polyclinics. Key to the effort was equipping these facilities with a broader range of new and upgraded medical technology. Dr de Armas offers MEDICC Review her reflections on the results five years later.

    Aims: Fecal indicator bacteria concentrations were evaluated in Havana Bay. Methods: Concentrations of traditional fecal indicator bacteria were calculated between April 2010 and February 2011, by MPN methods. Concentrations of thermo tolerant coliform (CTT), Escherichia coli, fecal streptococci (EF), intestinal enterococci (ENT) in seawater, and Clostridium perfringens in sediment surface, were determined. Results: CTT and E. coli levels were far above Cuban water quality standard for indirect contact with water, showing the negative influence of sewage and rivers on the bay. The EF and ENT were measured during sewage spills at the discharge site and they were suitable indicators of fecal contamination, but these indicators didn't show the same behavior in other selected sites. This result comes from its well-known inactivation by solar light in tropical zones and the presumable presence of humid acids in the waters of the bay. Conclusion: Fecal indicator bacteria and its statistical relationships reflect recent and chronic fecal contamination at the bay and near shores.

    Havana Bay is a typical bag-type located in the Western-North Coast of the Republic of Cuba. Since 1980 it has been the object of a study for sea bottom rehabilitation and improvement of quality of the waters, where the final objective will be the recovery of the coastal and marine ecosystem. Thirteen surface samples of the Havana Bay (Cuba) were collected and analysed by X-Rays spectrometry. Some majority elements (Si, Ca, K, Na, S, Cl, Al, Fe, Mg, C and O) were measured by scanning electron microscopy (SEM) coupled with microanalysis to perform geomorphologic analysis. Nine elements (Ca, Fe, Ti, Mn, Cu, Zn, Sr, Zr and Pb) have been measured using an Energy Dispersive X-Ray Fluorescence (EDXRF) with a Si(Li) detector. Multivariate statistical was used for the analysis. The concentration levels showed this bay as the most polluted in Cuba. The highest contents of Cu, Zn and Pb were obtained in Atares and Marimelena Cove; these elements are indicators of urban as well as industrial pollution. (author)

    2011-04-01

    Full Text Available The environmental quality of the Baracoa river estuary was studied from the physic (temperature and salinity, chemic variables (dissolved oxygen, oxygen biochemical demand (DBO, oxygen chemical demand (DQO, nitrogen cycle, inorganic phosphorus and total phosphorus and the microbiological variables (total and thermotolerant coliforms and faecal streptococci. The samplings were made on February 2006, May and October 2007. Spatial distribution of the physical and chemical parameters measured suggests that the estuary is dominated by the marine conditions. The salinity and temperature analyses show that in general the characteristics of the estuary could be influenced by the contribution of the river basin drainage. In general, the concentrations of the measured parameters in the Baracoa river estuary, strongly suggest that this area is under influence of human activities on the river basin, due to the low levels of dissolved oxygen and an oxygen average deficit of -1.6 mg/L. nthropogenic actions in this estuary are mainly related to the emission of domestic and farming rejects without suitable treatment. This is visibly associated with the observed values of the total coliforms concentrations as well as the concentration of faecal streptococci, that surpassed reference values from the Cuban norm for water quality, following on bad or doubtful quality levels pointing out negatively measurements made next to the communication channel the estuary and the El Doctor lagoon.

    Concentrations of ten metals were evaluated in surface sediments along Cauto River by dispersive energy X-Rays Fluorescence using External Standard Method. The results showed that heavy metal concentrations (in mg/kg; Fe in %) were 1.46-2.77, 8.8-12.0, 16-25, 117-140,35-56, and 40-48. for Fe, Co, Ni, Cu, Zb and Pb respectively, generally decreasing along the course of the river. Geo accumulation indexes were categorized between strongly to very strongly polluted for Cu and Co in all the stations. The calculation of enrichment factors (EF) showed that Co and Cu were enriched whereas the others metals were depleted. Concentrations of Cu and Ni were higher than Effect range low (ERL) but still below Effect range medium (ERM) value established by NOAA. Heavy metal concentrations found in the present study were comparable to other zones of the country and other regions of the world. In the last years, a considerable increase of Pb concentrations was found indicated more anthropogenic inputs. Based on the calculated indexes, Cauto River zone can be classified as unpolluted to moderately polluted environment. (Author)

    One of the challenges that must be face by a growing society is its waste management. This is crucial in the particular case of developing countries like Cuba. Waste to energy is a well-established technology for municipal solid waste (MSW) treatment. The aim of this work was to estimate the energetic potential of MSW in the city of Havana. An average low heating value (LHV) of 7.35 MJ/kg was estimated by applying different models. From the mass and energy balances, the emissions and the energy recovered for electricity generation were determined. Two steam turbine configurations (back – pressure and condensing) were designed by a rigorous method and later simulated in Aspen Plus simulator. The results showed that for a feeding rate of 49.5 tonh-1 of MSW it was possible to generate 257 GWh per year with an overall plant efficiency of 25.4% in a four-stage turbine. (author)

    Cuba is a unique country, and despite limited economic development, has an excellent health system. However, the prevalence of asthma symptoms in children in Havana, Cuba, is unusually high. As early life exposures are critical to the aetiology of asthma, we have studied environmental influences on the risk of wheezing in Cuban infants. Cross-sectional study. A random sample of 2032 children aged 12-15 months living in Havana was selected for inclusion in the cohort. Data were collected using questionnaires administered by researchers. Of 2032 infants invited to participate, 1956 (96%) infants provided data. The prevalence of any wheeze was 45%, severe wheeze requiring use of emergency services was 30% and recurrent wheeze on three or more occasions was 20%. The largest adjusted risk factors for any wheeze were presence of eczema [odds ratio (OR) 2.09; 95% confidence interval (CI) 1.48-2.94], family history of asthma (OR 2.05; 95% CI 1.60-2.62), poor ventilation in the house (OR 1.99; 95% CI 1.48-2.67), attendance at nursery (OR 1.78; 95% CI 1.24-2.57), male sex (OR1.52; 95% CI 1.19-1.96) and the number of smokers in the house (P Cuba. As the prevalence of smoking in the house is high (51%), intervention studies are required to determine effective strategies to improve infant health.

    Full Text Available Our main objective is to verify the Spanish problems of Spanish estanco relative to its main supplier, the Island of Cuba. The return to direct management by the Monarchy of the production, sale and export of Cuban tobacco as a leading provider of Metropolitan estanco, once passed the accident of taking of Havana by the English, was accompanied by the expansion of culture in the Island, but not the increase in longterm consumption of the product in the Metropolitan estanco. Two types of tobacco, the Virginian, and especially the Brazilian one, continued to maintain a privileged position in the Spanish market. On the other hand, the more opening of Havana to American market coincides with the creation of estancos in the rest of America. According to the known estimations, at least until the period of the War of Independence of the Thirteen Colonies, the solution to the problems of excess production did not take place in the Antillean Island

    Manatees (Trichechus manatus latirostris) in Florida utilize intake and effluent canals of power plants as resting and thermoregulatory habitat. We report the use of a power plant canal in Cuba by a known Florida manatee, the first documented case of movement by a manatee between Florida and Cuba. In January, February, and April 2007, two manatees (mother and calf) were reported entering a power plant canal in north Havana, Cuba. The larger manatee had several distinctive scars which were photographed. Digital images were matched to a previously known Florida manatee (CR131) with a sighting history dating from December 1979 to July 2006. Exchanges of individuals between Florida and Cuba may have important genetic implications, particularly since there appears to be little genetic exchange between the Florida manatee subspecies with populations of the Antillean manatee subspecies (T. m. manatus) in Puerto Rico and the Dominican Republic.

    In this work, the levels of Cu, Pb, Zn, Cd, Cr and Cd in roots of EC which grow in a river near an important landfill in Havana City are assessed. This landfill, known as street 100 receives daily 1,600 tons of solid wastes from the city, from them, approximately 45-50% are domestic wastes, 10-15% are industrial wastes and 25-30% are other type wastes. The leachate of the landfill is discharged without treatment into Almendares River. Some reports indicate that levels of metals in the leachate and in the river surface water are relatively low, contrary to the one should wait, due to the nature of the deposited waste- type

    This work examines the relationship between population growth and economic development in Latin America and assesses progress in the 10 years since the Bucharest World Population Conference. The Latin American population increased from about 159 million in 1950 to 275 million in 1970 and around 325 million in 1980. The rate of growth reached a maximum of 2.8%/year in the early 1970s and has now declined to about 2.3%/year. The regional growth rate is a product of population dynamics that differ greatly in individual countries. Crude birth rates declined in every country of Latin America between 1975-80, but still exceeded 40/1000 in 1980-85 in Bolivia, Ecuador, El Salvador, Haiti, Honduras, and Nicaragua. Current fertility is the result of the different trajectories of the demographic transition in different countries. While fertility in Argentina, Cuba, and Uruguay underwent a slow but sustained decline that began prior to 1960, other countries including Colombia, Costa Rica, Chile, and Venezuela began an accelerated fertility decline in the 1960s that diffused rapidly through all age and social groups. Other countries have still not entered a definite phase of fertility decline. Mortality rates have declined appreciably in Latin America in the past few decades although they remain high in some countries. After the end of World War II and until the mid-1970s, most countries of the region experienced rapid economic growth coupled with profound changes in the productive structure. The industrial labor force grew in almost all countries along with urbanization, the decline of agricultural employment, and the increase of the tertiary sector. These and other important economic advances through the mid-1970s occurred despite rapid population growth, and the beginning of the fertility decline coincided with slowing economic growth that saw negative rates in 1981-82. Various studies have shown that not all population sectors were incorporated in the process of economic

    Full Text Available During 70´s and 80´s of the last century, the promotional cultural poster in Santiago de Cuba gained a remarkable peak, due to historical and culturals conditions. Many important institutions were founded, that promote graphic design and sociocultural actions in the city, expressed in a lot of cultural events in that period. Nonetheless is impossible deny the education that acquired artists and designers, who with their creations increased the graphic arts movement in Santiago de Cuba, because they had a unique style. Because they had developed a unique style, apart of the Havana´s art movement.

    A survey was conducted through the SECUBA (SEguridad alimentaria en CUba y Buena Alimentación) research program in Cuban healthy smokers living in Guantánamo and in Havana. The aim of the survey was to investigate biological and nutritional factors connected with the occurrence of zero epidemic neuropathy (EN) observed in Guantánamo urban area since the disease emerged in Cuba. Blood riboflavin status and carotenoid and selenium concentrations were higher in Guantánamo than in Havana smokers. Food dietary quantities of plantain banana, pepper (Capsicum spp.), bovine meat and milk products were higher in Guantánamo. Inversely, foods rich in cholesterol, especially eggs, were more consumed in Havana. Through riboflavin, carotenoid and selenium contents and specific antioxidants substances (indoleamines, capsaicin), the foods more consumed in Guantánamo could be considered as EN protective factors. Disease protective effects could be exerted via enhancement of defence mechanisms against free radical damage and related mechanisms focused on redox recycling of glutathione and local protection from carotenoids. Finally, the results of the present study should help Cuba, through a better EN control, to improve long-term food safety and define healthier dietary habits.

    The National Institute of Oncology and Radiobiology had a facility contaminated with 137 Cs. The contamination was produced by a leaking source stored in the place. First decontamination work was performed in 1988. Some highly contaminated floor tiles and other contaminated items were removed. Spent sealed sources stored in the facility were collected. The facility was closed because of the remaining contamination. As the Regulatory Body allowed the unrestricted use of the facility, decontamination and decommissioning were needed. D and D activities were requested to the CPHR. Contamination surveys conducted in 1999 confirmed the extent of contamination with 137 Cs. Items inside the contaminated area were carefully monitored and segregated. Six Radium sources were recovered. Physical and chemical methods of decontamination were used. For different reasons, the requirements established by the Regulatory Authority for decommissioning could not be achieved, and therefore the facility could not be released from regulatory control. A Radiological Status Report was done explaining the high cost of decontamination according to the established clearance levels. New alternatives were then proposed for decommissioning of this facility. (author)

    For the elimination of tuberculosis (TB) is necessary the surveillance of the incidence rate at the local level, as this is the first level of access to the health service. This study is aimed at providing a description of the spread and trend of the tuberculosis incidence rates in Marianao Municipality, Habana City by healthcare areas and age groups throughout the 1990-2000 period. The time series for the 1990-1994 and 1995-2000 incidence rates were analyzed employing a two parameter exponential smoothing method. The total percentage and annual average of variation was estimated. The healthcare areas were stratified. In 1990-1994, the rate rose from 11.1 to 25.8 per 105 inhabitants (33% of increase by year), having been most noticeable in Carlos J. Finlay and Portuondo health areas (respectively annual average 112.7% y 36.2% increases). Taking into account that the control program was strengthened in 1995, the rates dropped by 47.6% in this municipality during the 1995-2000 period. The Finlay and Portuondo areas respectively lowered their rates by 79.9% y 39.7% while the Gonzalez Coro area showed a 58.3% rise and 27 de Noviembre area had no major change. The age and above 60 group had the higher percentage of cases, recording 49.8% of the total and only one case among children under age 15 for the period. During this same period, only six cases of tuberculosis/human inmunodeficiency virus were diagnosed. The 27 de Noviembre area was the only one found to be at the unsatisfactory level according to the stratification. An initially upward trend, followed by a downward trend in tuberculosis was found to exist in the Marianao Municipality throughout the period studied. This disease was predominant among older adults.

    Soon after the Molecular Immunology Center (CIM) was established in 1994 (a founding institution of Havana's biotechnology and pharmaceutical campus known as the scientific pole), Dr Crombet completed her master's thesis there. She joined CIM's team in 1998 and in 2004 was designated Director of Clinical Research. She has participated in the research, development and clinical trials of some of Cuba's most innovative therapies and vaccines, including CIMAvax-EGF for non-small cell lung cancer patients. In 2015, this therapy completed Phase IV clinical trials in Cuba and is now used in primary health care services throughout the country's national health system. CIM and Roswell Park Cancer Institute (Buffalo, New York) received US Department of Treasury approval in 2015 to test CIMAvax-EGF and other CIM products in the United States, opening the way for the Food and Drug Administration (FDA) to consider joint ground-breaking Phase I and II clinical trials in the USA. Recent regulatory changes introduced by President Barack Obama may make applying for such licenses a thing of the past-at least that is what researchers hope. In any case, the work of Dr Crombet and the teams at CIM is making headway in cancer immunotherapy, within the broader goals of the institution's mandate…the subject of our interview.

    Acute myocardial infarction is one of the leading causes of death in the world. This is also true in Cuba, where no national-level epidemiologic studies of related mortality have been published in recent years. Describe acute myocardial infarction mortality in Cuba from 1999 through 2008. A descriptive study was conducted of persons aged ≥25 years with a diagnosis of acute myocardial infarction from 1999 through 2008. Data were obtained from the Ministry of Public Health's National Statistics Division database for variables: age; sex; site (out of hospital, in hospital or in hospital emergency room) and location (jurisdiction) of death. Proportions, age- and sex-specific rates and age-standardized overall rates per 100,000 population were calculated and compared over time, using the two five-year time frames within the study period. A total of 145,808 persons who had suffered acute myocardial infarction were recorded, 75,512 of whom died, for a case-fatality rate of 51.8% (55.1% in 1999-2003 and 49.7% in 2004-2008). In the first five-year period, mortality was 98.9 per 100,000 population, falling to 81.8 per 100,000 in the second; most affected were people aged ≥75 years and men. Of Cuba's 14 provinces and special municipality, Havana, Havana City and Camagüey provinces, and the Isle of Youth Special Municipality showed the highest mortality; Holguín, Ciego de Ávila and Granma provinces the lowest. Out-of-hospital deaths accounted for the greatest proportion of deaths in both five-year periods (54.8% and 59.2% in 1999-2003 and 2004-2008, respectively). Although risk of death from acute myocardial infarction decreased through the study period, it remains a major health problem in Cuba. A national acute myocardial infarction case registry is needed. Also required is further research to help elucidate possible causes of Cuba's high acute myocardial infarction mortality: cardiovascular risk studies, studies of out-of-hospital mortality and quality of care

    During the last few years the drastic cut in oil supply provoked a critical situation in Cuba. The shortage of domestic oil production and the absence of alternative energy sources, such as wide rivers and coal deposits, drove us to decide that the most promising option was to develop our huge peat deposits. However, there are problems concerning skills and finance. This report reviews the potential for peat development to date in the Cuban territory. The figures and characteristics are partly taken from the surveys done by the Russian and Cuban specialists during the 60's. There is some new data compiled from the work done more recently in some of the Cuban peat deposits. The conditions for draining and harvesting are very challenging and difficult if the peat deposits are to be developed without doing any unnecessary damage to the fragile environment of Cuban wetlands. However, if the required financing and skills are available, the work can be carried out and significant risks avoided

    Full Text Available Raul and Manolo are two Cuban men in their late sixties. Manolo left soon after Castro’s triumph to become a television celebrity in Miami. He returned in 1991 to make a clandestine film about the city which once was his. Raul never left his decaying city. He applauded the revolution, but little by little his enthusiasm soured. The paper examines the relationship of the two men to what was once the ultra modern Central Havana of the mid-1950s. Manolo’s froze on the day he left: his filmed city is silent, immobile, full of ghosts, almost empty, ugly, ruined. Manolo’s Central Havana processes and changes, it is noisy, busy, - but also it is ugly and ruined. Both lament the city as it once was. Only Raul sees hope of reconciliation.

    Full Text Available Article in Spanish, Abstracts in English and German.In the Realm of Ambivalence.The Question of Cuba in Alexander von Humboldt’s American TravelogueCuba has a special role in Alexander von Humboldt’s American travel narrative: Humboldt’s experience of colonial slave economy drives his optimistic philosophy, inspired by European Enlightenment, into a crisis, and brings to surface the inherent contradictions of his discourse. This phenomenon is particularly interesting from the perspective of literary criticism: Alexander von Humboldt conceives Cuba as a poetic space, where contradictions and ambivalences coexist. Already on the boat to the island from Venezuela he creates destablizing effects of sensual perceptions. He stages his landing in Havana as a moment of oppositional impressions. Within the symbolic topography of his geographic fantasy, Cuba functions as an imaginary in-between space. And Humboldt’s philosophical and aesthetic terminology undergoes a semantic recoding in Cuba: what was once used in a philosophical and aesthetic sense, now has become charged with an economic and political meaning.

    Trophic webs of reef fishes in northwestern Cuba. I. Stomach contents. Studies on the reef fishes of Cuba are not rare, but most have two basic limitations: small sample sizes and exclusion of small species. Our study sampled more species and larger samples in the sublitoral region of Havana city (23 degrees 7.587' N, 82 degrees 25.793' W), 2-18 m deep. We collected fish weekly from October 2004 through February 2006 with traps and harpoon. Overfishing has modified the fish communities. We used the relative importance index to describe the diets of carnivore and omnivore species, and a modification of the relative abundance method for the herbivores and sponge-eating species. The main food items are benthonic crustaceans (crabs, shrimp, copepods) and bony fish (mainly demersal species). Most species are eurifagous and thus, less affected by anthropic disturbance than specialist feeders.

    To characterize and establish a clinical definition of the optic neuropathy that appeared in epidemic form in Cuba in 1992 and 1993. At the invitation of the Cuban Ministry of Health, Havana, members of ORBIS International and the Pan American Health Organization, assembled teams that traveled to Cuba in May 1993. We were initially briefed by Cuban national experts in the areas of virology, nutrition, toxicology, ophthalmology, neurology, and public health. We then examined 20 patients on our own. Thirteen of these patients underwent a comprehensive neuro-ophthalmologic examination, including neurologic examination, ophthalmologic examination, visual fields, optic nerve function studies, contrast sensitivity studies, and funduscopy. We returned 4 months later to perform an additional 12 comprehensive neuro-ophthalmologic and follow-up examinations. Only seven of the 13 patients who were alleged to have the optic form of the epidemic and who were rigorously and systematically examined on the first visit demonstrated a bilateral optic neuropathy. These seven patients had several features that included decreased visual acuity, poor color vision, central scotomas, decreased contrast sensitivity, saccadic eye movements, and most prominent and distinctive of all, nerve fiber layer wedge defects of the papillomacular bundle. Our clinical definition was then implemented by the Cuban ophthalmologists and epidemiologists. On returning 4 months later, we found that all newly presented patients were correctly diagnosed to have the epidemic disease. With the new case definition and the application of a few simple psychophysical tests, the false-positive rate of diagnosis became much lower. After vitamin therapy, we reexamined the patients seen on our initial visit, and all showed marked improvement. The Cuban epidemic was characterized by an optic neuropathy with features that were similar to those of tobacco/alcohol amblyopia and Leber's optic atrophy. Recent political

    Presenting physical performance tests' (PPTs) descriptive reference values and prevalence according to gender and age-group regarding a representative sample of non-institutionalised older adults (aged 60 and over) living in Bridgetown (Barbados) and Havana (Cuba). This was a cross-sectional, population-based household survey. In Bridgetown and Havana, respectively, 1,508 and 1,905 subjects were examined who had been selected by probabilistic sampling. PPTs included handgrip strength, standing balance, timed repeated "chair stand" and "pick up a pen." The results from Bridgetown and Havana showed that values (mean ± standard deviations and percentiles) for men were greater than women in handgrip strength and "chair stand" tests (p≤0.01). Increasing age led to both genders having reduced (p≤0.001) prevalence of people having better results for each test (based on chi-square). Men had proportionately better scores than women in the four tests. The data suggested that younger people and men had better physical performance. Men and women in both countries had differences regarding the prevalence of people unable to perform the tests and better test results, according to the test and age-group. The data provided information about the range of performance that can be expected from people in different ages and helped understand usual rates of change in age-groups.

    Innovative technologies have enabled new opportunities for collecting, analyzing, and sharing information about cultural heritage sites. Through a combination of two of these technologies, spherical imaging and virtual tour environment, we preliminarily documented one of Cuba's National Schools of Art, the National Ballet School.The Ballet School is one of the five National Art Schools built in Havana, Cuba after the revolution. Due to changes in the political climate, construction was halted on the schools before completion. The Ballet School in particular was partially completed but never used for the intended purpose. Over the years, the surrounding vegetation and environment have started to overtake the buildings; damages such as missing bricks, corroded rebar, and broken tie bars can be seen. We created a virtual tour through the Ballet School which highlights key satellite classrooms and the main domed performance spaces. Scenes of the virtual tour were captured utilizing the Ricoh Theta S spherical imaging camera and processed with Kolor Panotour virtual environment software. Different forms of data can be included in this environment in order to provide a user with pertinent information.

    Although lysosomal storage disorders (LSDs) are considered individually rare, as a group they present a non-negligible frequency. Few studies have been made of populational occurrence of LSDs; they have been conducted predominantly on Caucasian populations. We studied the occurrence of LSDs in Cuba. Data from individuals who had been referred to the Institute of Neurology and Neurosurgery in Havana from hospitals all over the country between January 1990 and December 2005 were analyzed. This institute was the only laboratory to provide enzyme-based diagnostic testing for 19 LSDs in Cuba during this period. Occurrence rates were calculated by dividing the number of postnatal diagnoses by the number of births during the study period. The combined occurrence of LSDs in Cuba was 5.6 per 100,000, lower than that reported in other studies conducted on Caucasian populations. The most frequent individual LSDs were: mucopolysaccharidosis type I (1.01 per 100,000) and, surprisingly, alpha-mannosidosis (0.72 per 100,000) and fucosidosis (0.62 per 100,000). These findings may be related to specific genetic characteristics and admixture of the Cuban population. This is the first comprehensive study of the occurrence of LSDs in Cuba. We conclude that the epidemiology of these diseases can vary regionally, and we stress the need for similar surveys in other Latin American countries.

    One of the main difficulties to develop nuclear application research is the lack of nuclear facilities. Different approaches and initiatives have been raised looking for more comprehensive exchanges. However, it is still necessary to strengthen regional cooperation in nuclear applications, in particular in the common use of accelerators and other nuclear facilities, based on a cooperative scheme in which each country contributes with its own facilities. The Microtron MT-25 Project in Cuba is proposed to deal with this kind of scheme. The construction of an electron accelerator up to 25 MeV, called Microtron MT-25, was finished in 1990 for Cuba, as a result of the collaboration of Cuban and Russian physicists in the Joint Institute for Nuclear Research in Dubna, Russia. The Microtron MT-25 is an electron cycle-accelerator which allows electrons, gamma rays and neutrons to be obtained. The principal characteristics of the accelerator and radiation are described in the paper. The Microtron-Havana facility is conceived for fundamental and applied research. The fundamental research topics of interest are photonuclear reaction studies, Nuclear Astrophysics reactions and photofission reactions. The applied research program involved in the Microtron Project consists of Gamma and Neutron Activation Analysis applied in Environment, Agriculture, Geology, Minerals, as well as materials science. Production of radioactive sources and radioisotopes. Medical and biological applications.To develop the research program, interested institutions need to form a User's Club. It will be formed, among others, by Brazil (Institute of Physics, Univ. Sao Paulo, Linear Accelerator Lab.), Argentina (Tandem Accelerator, called Tandar), Mexico (Institute of Physic, UNAM, Experimental Physics Department), Cuba (ISCTN, CEADEN, Isotopes Center, and IMRE from Havana University.) The participation of the members in the program exploitation will be based on projects in which the financial matters and

    Introduction Tuberculosis (TB) is a major cause of illness and death throughout the world. The World Health Organization's Global Plan to Stop TB 2006-2015 proposes that countries cut TB mortality by half compared to 1990 rates. In Cuba, TB mortality declined steadily throughout the 20th century, particularly after 1960. Objective Describe TB mortality distribution and trends in Cuba from January 1998 to December 2007 by infection site, sex, age and province, and determine progress towards the WHO's 2015 target for TB mortality reduction. Methods A time series ecological study was conducted. Death certificates stating TB as cause of death were obtained from the Ministry of Public Health's National Statistics Division, and population data by age group, sex, and province were obtained from the National Statistics Bureau. Crude and specific death rate trends and variation were analyzed. Results TB mortality declined from 0.4 per 100,000 population in 1998 to 0.2 (under half the 1990 rate) in 2007. Clinical forms of the disease, both pulmonary and extrapulmonary, also declined. The highest mortality rates were found in males and in the group aged ≥ 65 years. Rates were also highest in the capital, Havana, with extreme values of 0.73 and 0.39 per 100,000 population at the beginning and end of the period, respectively. Conclusions Deaths from TB declined steadily compared to total deaths and deaths caused by infectious diseases. The Global Plan to Stop TB target was met well ahead of 2015. If this trend continues, TB is likely to become an exceptional cause of death in Cuba.

    Full Text Available The article seeks to analyze the role of the changes introduced by the administration of the former president Barack Obama in 2014-2016 into the bilateral US-Cuba relations; and the way in which the new presidential team are to reorganize this direction. The question on the attitude of Donald Trump towards currently existing policies aimed at solving the long-lasting problem with Cuban socialism is especially interesting since new US president has multiple times condemned the old ways practiced by the former establishment, but at the same time has shown readiness to act in a straight-forward and confrontational manner. One of contributors of the paper, Santiago Perez Benitez, deputy director of the Center for International Political Studies in Havana, is attempting to provide his professional expertise in granting an insider view from the Cuban side, evaluating the progress made since the 2014 and interpret the notion of the upcoming policy changes in Washington. The importance of the Cuban issue in the framework of US. policy in the Western hemisphere is explained by the fact that a solution in this sphere could help remake a negative image of Pan-American policies that haunts Washington. Cuban issue has also been long considered a possible key for reestablish-ment of trust between the United States and Latin American countries. For president Trump, quite unpopular judging by the polls, Cuban issue also has a potential to earn support of his own constituents, who strongly support lifting the embargo from Cuba. However now after certain decisions of Donald Trump the future of US-Cuban relations seems to get gloomier by the day.

    This article explores quality-of-life aspects among gay, lesbian, bisexual, and straight male and female students in Havana (Cuba), Tromsø (Norway), Hisar (India), and Cape Town (South Africa). In the period 2004-2005, a questionnaire survey on sexuality, happiness, and life satisfaction was undertaken among 339 students from the University of Havana, 144 students from the University of Tromsø, 200 students from Guru Jambheswar University, and 189 students from the University of the Western Cape. The majority of the participants were straight and, in Hisar and Cape Town, few of those who regarded themselves as gay/lesbian/bisexual had engaged in sex with a person of the same gender. In all cities, straight men and women scored higher than gay, lesbian, and bisexual persons on the quality-of-life measures. Quality of life among gay/bisexual men and lesbian/bisexual women was higher in cultures with accepting attitudes toward homosexuality than in cultures with restrictive attitudes.

    Cuba's economy spiraled downward in the 1990s, reeling from the collapse of European socialism and a tightened US embargo. To mitigate the crash's drastic effects, measures were adopted that transformed our urban landscape, especially in large cities such as Havana, paradoxically linking the period to nascent health-promoting options. One of the most important was the introduction of bicycle lanes on city streets, paths daily ridden by people on the over one million bicycles imported to offset the nearly nonexistent public transport caused by fuel shortages. Second, urban gardens began to sprout up, involving urban dwellers in production of their own food, particularly vegetables. Without minimizing the impact of the crisis, these two seemingly disparate phenomena meant people were getting more exercise, consuming fewer fats and carbohydrates and more fresh vegetables. People were even breathing fresher air, with fewer CO2-belching trucks, old cars and buses on the streets and less diesel used to transport produce in from afar.

    Cryptoccosis--systemic mycosis caused by Cryptococcus species--has considerably raised its incidence in the last years, mainly associated with the human immunodeficiency virus infection. It has also been described in animals, but rare cases. a case of a female cheetah (Acinonyx jubatus) kept in the Nacional Zoo of Havana was presented. The animal came from South Africa. She began losing weight, and suffering asthenia, anorexia and breathing problems with abundant nasal secretion. mycological testing of these secretions disclosed the presence of serotype B Cryptococcus gattii. Because of the origin and captive condition of the animal, it was believed that the infection had been latent for 16 months at least. up to the present, in Cuba, all clinical Cryptococcus isolates were C. neoformans var. grubii, so it is considered that the infection was caught in the country of origin of the female cheetah. This is the first C. gattii isolate in Cuba from an animal coming from South Africa where this fungus is endemic.

    Obtain baseline information on the status of the basic capacities of the health sector at the local, municipal, and provincial levels in order to facilitate identification of priorities and guide public policies that aim to comply with the requirements and capacities established in Annex 1A of the International Health Regulations 2005 (IHR-2005). A descriptive cross-sectional study was conducted by application of an instrument of evaluation of basic capacities referring to legal and institutional autonomy, the surveillance and research process, and the response to health emergencies in 36 entities involved in international sanitary control at the local, municipal, and provincial levels in the provinces of Havana, Cienfuegos, and Santiago de Cuba. The polyclinics and provincial centers of health and epidemiology in the three provinces had more than 75% of the basic capacities required. Twelve out of 36 units had implemented 50% of the legal and institutional framework. There was variable availability of routine surveillance and research, whereas the entities in Havana had more than 40% of the basic capacities in the area of events response. The provinces evaluated have integrated the basic capacities that will allow implementation of IHR-2005 within the period established by the World Health Organization. It is necessary to develop and establish effective action plans to consolidate surveillance as an essential activity of national and international security in terms of public health.

    This paper presents the results of a quality control pilot study in diagnostic radiology carried out in 10 hospitals of Havana City, Cuba. The study included dosimetric determinations for two common radiographic protections: posterior-anterior chest and lateral lumbosacral spine. A total of 21 x-ray units and 12 dark rooms were evaluated. The deficiencies related to film processing, as well as other problems associated with the dark room are presented. The most significant problems related to equipment were: the lack of reproducibility and linearity of the x-ray generator and the non-coincidence of radiation and light fields. A great variability of the entrance surface dose for the same type of patient was recorded. Organ doses and effective dose for each radiographic projection were calculated for a reference patient. A plan of corrective actions to solve the deficiencies was implemented. It was decided to develop a national quality control program in diagnostic radiology. (Author) 12 refs

    INTRODUCTION The availability of monoclonal antibodies in Cuba has facilitated development and application of innovative techniques (immunoscintigraphy and radioimmunotherapy) for cancer diagnosis and treatment. Objective Review immunoscintigraphy and radioimmunotherapy techniques and analyze their use in Cuba, based on the published literature. In this context, we describe the experience of Havana's Clinical Research Center with labeled monoclonal antibodies for cancer diagnosis and treatment during the period 1993-2013. EVIDENCE ACQUISITION Basic concepts concerning cancer and monoclonal antibodies were reviewed, as well as relevant international and Cuban data. Forty-nine documents were reviewed, among them 2 textbooks, 34 articles by Cuban authors and 13 by international authors. All works published by the Clinical Research Center from 1993 through 2013 were included. Bibliography was obtained from the library of the Clinical Research Center and Infomed, Cuba's national health telematics network, using the following keywords: monoclonal antibodies, immunoscintigraphy and radioimmunotherapy. RESULTS Labeling the antibodies (ior t3, ior t1, ior cea 1, ior egf/r3, ior c5, h-R3, 14F7 and rituximab) with radioactive isotopes was a basic line of research in Cuba and has fostered their use as diagnostic and therapeutic tools. The studies conducted demonstrated the good sensitivity and diagnostic precision of immunoscintigraphy for detecting various types of tumors (head and neck, ovarian, colon, breast, lymphoma, brain). Obtaining different radioimmune conjugates with radioactive isotopes such as 99mTc and 188Re made it possible to administer radioimmunotherapy to patients with several types of cancer (brain, lymphoma, breast). The objective of 60% of the clinical trials was to determine pharmacokinetics, internal dosimetry and adverse effects of monoclonal antibodies, as well as tumor response; there were few adverse effects, no damage to vital organs, and a positive

    The Havana City historical center is being recuperated in the las years. Numerous are the colonial houses with values typical wall painting as internal decoration that need to be investigated and restored. The pigment identification is essential to have knowledge about pictorial technique and to help and monitor the restoration process. The identification of inorganic pigments in the Havana colonial wall painting has been not almost studied. The opportunity to have a new Portable XRF system in the Archaeometry laboratory of the Conservation and Restoration Gabinet of Havana Historitian Office allows to investigate the wall painting, samples that because of its more of this nature it would be impossible to move to the laboratory for non destructive analysis. The most of the pigment are made of inorganic elements and they can be identified property by XRF technique. All complete archaeometric investigation has to use several technique and to work in a multidisciplinary research team to give a fundamental answer about the past, The suitable techniques selection to employ depends of the art Historitian and archaeologist's questions. The pictorial technique are traditionally investigated using stratigraphical information obtained by Optical Microscopy and organic compound determination by Gas Chromatography. The global analysis of the results from the different employed techniques and the discussion from the restaurateur point of view is presented

    To investigate the association between various anthropometric indexes of obesity with arterial hypertension in elderly from Barbados (Bridgetown) and Cuba (Havana). Cross-sectional data were extracted from the Survey on Health, Aging and Well being in Latin America and the Caribbean (SABE). In Bridgetown and Havana, respectively, 1508 and 1905 subjects ( ≥ 60 years) were examined, and were selected by a controlled sampling design. The occurrence of hypertension was assessed by self-report. Multiple measurements of adiposity were used including body mass index (BMI ≥ 28 kg/m(2)), waist hip ratio (WHR = > 0.95 men; > 0.80 women), waist to height ratio (W/ht. = > 0.50) and waist circumference - WC(L) ( > 88 cm, women; > 102 cm, men) e WC(OK) ( > 90.3 cm, women; > 91.3 cm, men). Binary logistic regression analyses (Odds Ratio) were used to measure strengths of relationships. In the elderly of Bridgetown, the final design (adjusted for age, education, race, smoking, regular physical activity and diabetes) shows that, in men, WC(OK) and W/Ht were associated with hypertension, and in women, WCL and WCOK were the indexes associated. In the Cuban elderly, the final design shows that, with the exception of WHR, all indicators were associated with hypertension. WCOK and W/ht were the indexes most strongly associated with the outcome. The explanatory power of anthropometric indicators when determining the outcome differed between men and women, as well as between cultural groups living in relative proximity (Barbadians and Cubans).

    Diarrhoea morbidity shows a slow increasing tendency during the last 10 years in Cuba. In young children the compromise of the gastric acid barrier after a chronic infection with Helicobacter pylori (Hp) is discussed in pathogenic relation to gastritis, duodenal ulcer, chronic diarrhoea, short stature, malabsorption of the B-complex vitamins and malnutrition. The Hp contamination level of the population of the developing world is estimated to be considerably high. Endoscopic studies carried out in Cuban subjects with upper gastrointestinal symptoms show contamination values of 60 to 100%. The current treatment of chronic diarrhoea does not include the elimination of Hp. Cuban children with upper gastrointestinal symptoms show contamination values of more than 60%. There are not available data on the contamination level in apparently healthy Cuban children or those with chronic diarrhoea. In March-April 2000 the prevalence of Hp infection measured in serum by chromatographic immunoassay for detection of Hp IgG antibodies was found to be 94 % in 20 infants and young children with persistent chronic diarrhoea and 100% in 11 apparently healthy children in Havana City. Children with diarrhoea showed a more evident affection of their nutritional status and a higher percentage of positive personal or familiar history of parasitism, giardiasis, gastritis, ulcer, stomatitis and glositis. The validity of the immunological tests in infants is discussed from the point of view of the antibody transference with breast milk. In a sample of 16 different children studied by the 13C-Urea-Breath-Test the contamination level was 50% of the children not affected by diarrhoea and only one of the 6 children with diarrhoea showed positive values

    The Cuba library offers four independent routines for multidimensional numerical integration: Vegas, Suave, Divonne, and Cuhre. The four algorithms work by very different methods, and can integrate vector integrands and have very similar Fortran, C/C++, and Mathematica interfaces. Their invocation is very similar, making it easy to cross-check by substituting one method by another. For further safeguarding, the output is supplemented by a chi-square probability which quantifies the reliability of the error estimate.

    Except for the people living with the disease, no others have so immersed themselves in Cuba's world of HIV/AIDS as Dr Jorge Pérez. It is a world of Cuban returnees from Angola's war against apartheid South Africa, gay and bisexual men, housewives, transactional sex workers, rebellious teenagers, and infected surgeons and scientists-a cultural kaleidoscope reflecting all the faces of AIDS. To more than one international author, he is simply "Cuba's AIDS doctor." Speaking to his patients at the Pedro Kourí Tropical Medicine Institute in Havana, it is easy to see why, but also to appreciate the courage, compassion, and persistent search for new knowledge that characterize the Institute's staff as a whole. Dr Pérez's story-now told in two books based on his diaries-is not his alone. MEDICC Review held two interview sessions with Jorge Pérez just days apart at the beginning of April: one before and one after his designation as the new Director of the Tropical Medicine Institute, where he previously served as Deputy Director and Chief of Hospital Services. More than strictly medical matters, the conversation turned to the human dimension of HIV/AIDS, the depth to which it has touched many directly and affected Cuban society as a whole, and the challenges ahead for Cuba's flagship institution for research and treatment of infectious diseases.

  20. Love in the Time of Diaspora. Global Markets and Local Meanings in Prostitution, Marriage and Womanhood in Cuba

    Directory of Open Access Journals (Sweden)

    Ingrid Kummels

    2014-06-01

    Full Text Available Interrelations between the circulation of images concerning race and gender in the context of global hierarchies and new local forms and meanings of partnership and prostitution in Cuba have not been adequately understood until now. This is due to the image of a “sudden” revival of prostitution, after it had allegedly been eradicated in socialist Cuba. Exploring prostitution, marriage and womanhood in Havana from a historical perspective and examining jineterismo as part of the local ‘informal’ economy, this article demonstrates how these institutions were modified in a global context long before the 1990s. In the transcultural relations between foreigners and locals, models of womanhood, partnership and love were not merely ‘given’ by the social structure in the context of a globalized modernity. Instead they were to a large extent influenced by ideas concerning gender, race and morality, created and negotiated by agents as they interacted, Cuban women having resorted to these ideas and related institutions as arenas of empowerment.

    Health systems and services research by nursing personnel could inform decision-making and nursing care, providing evidence concerning quality of and patient satisfaction. Such studies are rather uncommon in Cuban research institutes, where clinical research predominates. Assess the results of a strategy implemented between 2008 and 2011 to develop nursing capacity for health systems and services research in 14 national research institutes based in Havana. The study comprised four stages: description of approaches to health systems and services research by nurses worldwide and in Cuba; analysis of current capacities for such research in Cuba; intervention design and implementation; and evaluation. Various techniques were used including: literature review, bibliometric analysis, questionnaire survey, consultation with experts, focus groups, and workshops for participant orientation and design and followup of research projects. Qualitative information reduction and quantitative information summary methods were used. Initially, 32 nursing managers participated; a further 105 nurses from the institutes were involved in research teams formed during intervention implementation. Of all published nursing research articles retrieved, 8.9% (185 of 2081) concerned health systems and services research, of which 26.5% (49 of 185) dealt with quality assessment. At baseline, 75% of Cuban nurses surveyed had poor knowledge of health systems and services research. Orientation, design and followup workshops for all institute teams developed individual and institutional capacity for health systems and services research. Post-intervention, 84.7% (27) of nurses reached good knowledge and 14.3% (5) fair; institutional research teams were formed and maintained in 9 institutes, and 13 projects designed and implemented (11 institutional, 2 addressing ministerial-level priorities) to research nursing issues at selected centers.

    The use of phosphates for the production of fertilisers is a practice broadly diffused in the world. Their wide use is associated to the contribution of this material to formulation of Nk fertilisers. It is known in turn that phosphates have in their composition appreciable quantities of radioactive elements of natural origin. For this reason the use of phosphates in the composition of fertilizers can cause a radiological impact to both workers and public during all the phases of extraction and processing of phosphates, as well as during the production and application of these fertilizers. Finally the transfer of radionuclides contained in the fertilizers to the products of human consumption (vegetables, milk, meat) can produce an additional radiological impact on population. In Cuba there exist six locations of phosphoric rocks, located in the counties of Pinar del Rio, Havana, Matanzas, Sancti-Spiritus and Holguin. From these deposits there were studied the two ones which are in exploitation: 'La Pimienta' deposit, located in the West part of the country and 'Trinidad de Guedes' deposit, located in the Centre-West of Cuba. Paper shows the results obtained by the Center for Radiation Protection and Hygiene (CPHR) in the determination of radionuclides concentrations in collected in the sites samples. Based on these results and taking into account both the features of routine works carried out in the sites and the later use of collected mineral as fertilizer, doses to mining workers and to members of the public were estimated. Estimated doses are in the range 0.3 - 2.70 mSv per year for workers and in the range 1.3 - 17 μSv per year. (author)

  10. Cuba's oil crisis spells trouble for Castro

    1992-01-01

    This paper reports on Cuba's oil crisis which presents long term woes for the government of Fidel Castro but new opportunities for foreign petroleum investment. That's the main thesis of a study by East-West Center (EWC), Honolulu. Since the cutoff of subsidized oil supplies from the former Soviet Union at the first of the year, Cuba has endured a crippling loss of export revenues and draconian energy rationing measures at home. The Soviets had reduced oil supplies to Cuba since 1989 after decades of providing the Castro government with subsidized oil supplies. Former Soviet President Mikhail Gorbachev exempted Cuba from paying market prices for Soviet oil in 1991 while requiring that of Soviet trading partners in eastern Europe. With the collapse of Communism in the former U.S.S.R., however, oil supplies from that region are available to Cuba only at market prices and for hard currency. That has triggered a crisis in the Western Hemisphere's sole Communist regime as Cuba's gross special product - equivalent to GNP - fell by 5% in 1990 and a further 20% in 1991. The foreign exchange loss of $1.6 billion stemming from the loss of Soviet subsidized oil supplies exceeds that of total foreign exchange earnings from all other sources. If Cuba imports oil in 1989 volumes at current prices, its oil import tab alone will be $1.3 billion, EWC projects

    To build a national Cuban capacity for training environmental health professionals directly linked to the needs of policy-makers and communities. The University of Manitoba and University of British Columbia collaborated with an established training centre in Cuba (the Instituto Nacional de Higiene y Epidemiologia--INHEM) and new centres in the Central (Santa Clara) and Eastern (Santiago) regions of the country. Cuba. In the mid-1990s, a comprehensive curriculum (masters and diploma programs) was collaboratively developed, applying interactive teaching methods, and was delivered through a series of workshops and other interactions in Cuba, and short-term visits to Canada by Cuban PhD students. The collaboration was successful in fulfilling capacity-building targets (over 50 Masters graduates, 467 Diploma graduates, over 30 trained core faculty in all regional centres as well as new curriculum and new accredited regional programs). Alongside this, a number of collaborative community-based research projects were undertaken in all three regions (drinking water in Santiago; housing and urban renewal, and dengue control in Havana; and tourism-related effects, and effective intersectoral management of population health determinants in Santa Clara). The collaboration led to adopting new strategies for challenges such as a dengue epidemic in 2002, and new research on the effectiveness of intersectoral management of risks of particular interest to both Cuban and Canadian policy-makers. It triggered an ambitious collaboration between the Canadian-Cuban team and colleagues in Ecuador in order to build a similar national network there, built on South-South and North-South links.

    Obesity and non-insulin dependent diabetes mellitus (NIDDM) are common in the Third Age and increasing in Cuba. Among the life-style changes associated with increased prevalence of obesity and its related disorders, diet and activity patterns are prime candidates. The transition to this life-style model may induce a decrease in the energy needs. There is an urgent need for tools which have been validated for measuring diet and physical activity in nutritional studies in the developing world, but also a more urgent need for reference values for the total energy requirements of healthy elderly people. Regular physical activity reduces the likelihood to develop diseases that characterise the metabolic cardiovascular syndrome. Previous studies done in Havana showed values of physical activity level (PAL) which are lower than the reported for elderly subjects. Elderly people living in rural areas use to have physical activity levels which differ from the observed in urban areas. With the purpose of estimating the energy requirements, a group of 40 apparently healthy people older than 60 years of age living in a rural mountain community will be submitted to a medical, epidemiological, dietary, anthropometric and insulin resistance study. Physical activity will be determined by questionnaire and by the calculation of the PAL from the basal metabolic rate (BMR) and total energy expenditure (TEE) measured with the doubly-labelled water method (DLW). Associations with the prevalence of insulin resistance and obesity will be assessed. (author)

    Full Text Available In December 2005, eleven Cuban educational advisers arrived in Timor-Leste to begin work on a national literacy campaign. Adapting the program known in Latin America as Yo, Sí Puedo (Yes I Can, the Cubans trained over 400 local tutors to run classes in every part of the country, using a method they call ‘alphanumeric’, delivered via audiovisual technology. The campaign was launched in March 2007, and the first classes began in June of that year. By September 2010, three years later, over 70,000 adults, over one fifth of the total illiterate population, had successfully completed a thirteen week basic literacy course. Drawing on original research undertaken in Timor-Leste between 2004 and 2009, followed by further investigations in May 2010 in Havana, Cuba, this paper describes the Timor-Leste campaign, locating it within the historical commitment of the country’s independence movement to adult literacy, and the broader context of Cuba’s international literacy work.

    One of the most important problems in modern radioecology is the lack of able information about the features of radionuclide migration in tropical and subtropical environment. The development of nuclear energy and the enhancing in the applications of nuclear techniques in those latitudes indicate that studies in this area are necessary. Cuba is carrying out studies on radioecological characterization of the principal food chains in the country. One of the objectives of these studies is to define the values of the transfer coefficients to be used in the evaluation programs for the assessment of the radiological impact of practices which involve ionizing radiation. This paper shows the results obtained in the determination of Sr-90 transfer coefficients in soil-grass-milk food chain in 'La Quebrada', a place near the Havana City where an important part of the milk that the citizens consume is produced. Transfer coefficients for Sr-90 were calculated on the basis of data collected during 5 years in the region. Soil-grass transfer coefficients are in the range 0.18-5 while grass-milk coefficients are in the range of 1.2x10 -4 - 6x10 -3 day/L. These values are in accordance with values reported by other authors in the literature. (authors). 4 refs., 2 tabs

    As health professionals in the United States consider how to focus health care and coverage to ensure better, more equitable patient and population health outcomes, the experience of Cuba’s National Health System over the last 5 decades may provide useful insights. Although mutual awareness has been limited by long-term political hostilities between the United States and Cuban governments, the history and details of the Cuban health system indicate that their health system merits attention as an example of a national integrated approach resulting in improved health status. More extensive analysis of the principles, practices, and outcomes in Cuba is warranted to inform health system transformation in the United States, despite differences in political-social systems and available resources.

    In the present paper the spatial distribution and temporal evolution of the saline intrusion in the most important aquifer of Havana province is presented. Results were obtained through the application of hydrochemical and isotopic tools. Studies were carried out within the framework of the IAEA Regional Project RLA/8/041. The survey was carried out in 2008 during the dry and rainy seasons. Sampling points were selected according to a monitoring network located along the north-south line following the main groundwater flow direction. Stable isotopes ({sup 2}H and {sup 18}O) were used to identify and characterize the groundwater origin and mixing processes. Changes in the chemical composition of groundwater were shown to be mainly controlled by the groundwater and seawater mixing process, followed by cation exchange reactions and a Ca-Mg precipitation process due to the strong influence of the costal wetland. A gradual decreasing of the spatial and temporal saline intrusion was observed. (author)

    In previous study a set of samples of fine and coarse airborne particulate matter collected in a urban area of Havana City were analyzed by Particle-Induced X-ray Emission (PIXE) technique. The concentrations of 14 elements (S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Br and Pb) were consistently determined in both particle sizes. The analytical database provided by PIXE was statistically analyzed in order to determine the local pollution sources. The Positive Matrix Factorization (PMF) technique was applied to fine particle data in order to identify possible pollution sources. These sources were further verified by enrichment factor (EF) calculation. A general discussion about these results is presented in this work. (Author)

    INTRODUCTION The professional practice of pediatric gastroenterology arose in Cuba as an expression of the specialty's development internationally and Cuba's new strategies in public health, and in response to national needs for health care expertise in digestive diseases of infants, older children and adolescents. OBJECTIVES Describe the history of pediatric gastroenterology's development in Cuba since its inception at the National Gastroenterology Institute in the early 1970s, its contributions, and efforts to extend it to pediatric hospitals throughout Cuba. EVIDENCE ACQUISITION This is a historical review based on document analysis. Institutional sources from the National Gastroenterology Institute and Ministry of Public Health were reviewed, as well as international and national literature on the history of pediatric gastroenterology and unpublished texts since its emergence in 1972. DEVELOPMENT Although pediatric gastroenterology has not been formally recognized as a medical specialty in Cuba, there have been important achievements in establishing a network of specialized health care services for digestive diseases of children and adolescents. Gastrointestinal endoscopy and other auxiliary diagnostic modalities have been introduced for children and play a major role in clinical trials and research. This article describes the international context that promoted the specialty's development in Cuba. Reference is made to specialized training from its initial stages in 1972, its consolidation as an emerging discipline in Cuban medicine, and its diffusion in Latin American and Caribbean countries. Professional development and specialized training to meet health human resource needs in pediatric hospitals are described, as well as Cuban participation in the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition. National and international milestones, publications, awards and recognitions that indicate advances despite difficulties are also

    Diarrhoea morbidity shows a slow increasing tendency during the last 10 years in Cuba. In young children the compromise of the gastric acid barrier after a chronic infection with Helicobacter pylori is discussed in pathogenic relation to gastritis, duodenal ulcer chronic diarrhoea, short stature, malabsorption of the B-complex vitamins and malnutrition. The Hp contamination level of the population of the developing world is estimated to be considerably high. Endoscopic studies carried out in Cuban subjects with upper gastrointestinal symptoms show contamination values of 60 to 100%. The current treatment of chronic diarrhoea does not include the elimination of Hp. Cuban children with upper gastrointestinal symptoms show contamination values of more than 60%. There are not available data on the contamination level in apparently healthy Cuban children or those with chronic diarrhoea. In March-April 2000 the prevalence of Hp infection measured in serum by chromatographic immunoassay for detection of Hp IgG antibodies was found to be 94% in 20 infants and young children with persistent chronic diarrhoea and 100% in 11 apparently healthy children in Havana City. Children with diarrhoea showed a more evident affection of their nutritional status and a higher percentage of positive personal or familiar history of parasitism, giardiasis, gastritis, ulcer stomatitis and glositis. The validity of the immunological tests in infants is discussed from the point of view of the antibody transference with breast milk. In a sample of 16 different children studied by the 13 C-Urea-Breath-Test the contamination level was 50% of the children not affected by diarrhoea and only one of the 6 children with diarrhoea showed positive values. This research contract proposes the study of contamination with Hp in Cuban children older than 2 years of age affected by chronic diarrhoea using the 13 C-Urea Breath Test and serological tests for detection of anti-Hp IgG antibodies.

    Cuba and its satellite islands represent the largest landmass in the Caribbean archipelago and a major repository of the region’s biodiversity. Approximately 13.4% of the Cuban territory is covered by wetlands, encompassing approximately 1.48 million ha which includes mangroves, flooded savannas, peatlands, freshwater swamp forests and various types of managed wetlands. Here, we synthesise information on the distribution and abundance of waterfowl on the main island of Cuba, excluding the numerous surrounding cays and the Isla de la Juventud (Isle of Youth), and report on band recoveries from wintering waterfowl harvested in Cuba by species and location. Twenty-nine species of waterfowl occur in Cuba, 24 of which are North American migrants. Of the five resident Anatid species, three are of conservation concern: the West Indian Whistling-duck Dendrocygna arborea (globally vulnerable), White-cheeked Pintail Anas bahamensis (regional concern) and Masked Duck Nomonyx dominicus(regional concern). The most abundant species of waterfowl wintering in Cuba include Blue-winged Teal A. discors, Northern Pintail A. acuta, and Northern Shoveler A. clypeata. Waterfowl banded in Canada and the United States and recovered in Cuba included predominantly Blue-winged Teal, American Wigeon and Northern Pintail. Banding sites of recovered birds suggest that most of the waterfowl moving through and wintering in Cuba are from the Atlantic and Mississippi flyways. Threats to wetlands and waterfowl in Cuba include: 1) egg poaching of resident species, 2) illegal hunting of migratory and protected resident species, 3) mangrove deforestation, 4) reservoirs for irrigation, 5) periods of pronounced droughts, and 6) hurricanes. Wetland and waterfowl conservation efforts continue across Cuba’s extensive system of protected areas. Expanding collaborations with international conservation organisations, researchers and governments in North America will enhance protection

    President Obama's announcement of U. S. policy change toward Cuba and increased freedom of interaction with the Cuban people opens unprecedented and long-awaited opportunities for the scientific and engineering communities in the U. S. and in Cuba to establish and expand collaborative efforts that will greatly advance U.S. and Cuba science and technology agendas. New rules for export of donated-only items for scientific use will bring researchers closer to the level of their professional peers around the world. Increasing Cubans' access to information will result in greater interactions between scientific communities and enable the sharing of ideas and discoveries that can fuel entrepreneurship on the island. The scientific community has expressed an extraordinary level of interest in the wide range of scientific opportunities that the new policy presents, in collaborating with their Cuban counterparts, and in supporting the development of scientific capacity in Cuba. In response to numerous expressions of interest and inquiries from the scientific community, the Office of the Science and Technology Adviser to the Secretary of State (STAS) has engaged in public outreach to inform the U.S. science and technology community of the implications of the new policy for collaborative research, emerging scientific opportunities, and the standing limitations for engagement with the people of Cuba.

    2007-01-01

    A monoenergetic neutron beam simulation study is carried out to determine the most suitable neutron energy for treatment of shallow and deep-seated brain tumors in the context of Boron Neutron Capture Therapy (BNCT). Two figures-of-merit, i.e. the absorbed dose for healthy tissue and the absorbed tumor dose at a given depth in the brain are used to measure the neutron beam quality. Also irradiation time, therapeutic gain and the power generated in the target are utilized as beam assessment parameters. Moderators, reflectors and delimiters are designed and optimized to moderate the high-energy neutrons from the fusion reactions 2 H(d;n) 3 He and 3 H(d;n) 4 He down to a suitable energy spectrum. Metallic uranium and manganese are successfully tested for fast-to-epithermal neutron moderation as well as Fluental TM for the neutron spectrum shifting. A semispherical target is proposed in order to dissipate twice the amount of power generated in the target, and decrease all the dimensions of the BSA. The cooling system of the target is also included in the calculations. Calculations are performed using the MCNP code. After the optimization of our beam-shaper a study of the dose distribution in the head had been made. The therapeutic gain is increased in 9% while the current required for one hour treatment is decreased in comparison with the trading prototypes of NG used for BNCT. (Author)

  2. HBV genotypic variability in Cuba.

    Directory of Open Access Journals (Sweden)

    Carmen L Loureiro

    Full Text Available The genetic diversity of HBV in human population is often a reflection of its genetic admixture. The aim of this study was to explore the genotypic diversity of HBV in Cuba. The S genomic region of Cuban HBV isolates was sequenced and for selected isolates the complete genome or precore-core sequence was analyzed. The most frequent genotype was A (167/250, 67%, mainly A2 (149, 60% but also A1 and one A4. A total of 77 isolates were classified as genotype D (31%, with co-circulation of several subgenotypes (56 D4, 2 D1, 5 D2, 7 D3/6 and 7 D7. Three isolates belonged to genotype E, two to H and one to B3. Complete genome sequence analysis of selected isolates confirmed the phylogenetic analysis performed with the S region. Mutations or polymorphisms in precore region were more common among genotype D compared to genotype A isolates. The HBV genotypic distribution in this Caribbean island correlates with the Y lineage genetic background of the population, where a European and African origin prevails. HBV genotypes E, B3 and H isolates might represent more recent introductions.

    As professional astronomer and science communicator, I want to share my personal experience communicating Astronomy and general science principles in maybe, the most popular science outreach devoted TV program in Cuba. It is broadcasted nationwide in a prime time schedule every Sunday. The Science Popularization on TV, is in a Third World Country hard to do if you want to produce attractive materials for a broad audience. Budgets constraints in most of the cases and lack of the technical equipment required to produce first class visual materials conspire, against motivation and creativity of local scientists and media professionals. A way to show the advance of the national scientific community in Science fields and connecting them in a friendly relation with a broad majority of the people, is to combine the wisdom and knowledge of the local scientists together with the most spectacular TV production of the first world countries. Commenting, analyzing and conveying the hard science into the public debate of the common citizens. Here is shown a way to convey cutting edge science to the general public, using limited resources to produce imaginative television productions, highlighting the development, knowledge and wisdom of the local scientists.

    The genetic diversity of HBV in human population is often a reflection of its genetic admixture. The aim of this study was to explore the genotypic diversity of HBV in Cuba. The S genomic region of Cuban HBV isolates was sequenced and for selected isolates the complete genome or precore-core sequence was analyzed. The most frequent genotype was A (167/250, 67%), mainly A2 (149, 60%) but also A1 and one A4. A total of 77 isolates were classified as genotype D (31%), with co-circulation of several subgenotypes (56 D4, 2 D1, 5 D2, 7 D3/6 and 7 D7). Three isolates belonged to genotype E, two to H and one to B3. Complete genome sequence analysis of selected isolates confirmed the phylogenetic analysis performed with the S region. Mutations or polymorphisms in precore region were more common among genotype D compared to genotype A isolates. The HBV genotypic distribution in this Caribbean island correlates with the Y lineage genetic background of the population, where a European and African origin prevails. HBV genotypes E, B3 and H isolates might represent more recent introductions. PMID:25742179

    Full Text Available From 1908 the Galician group in Cuba started to organize the popular “romerías”, typical of their country of origin. The initiative was not taken by the great regional societies but by the small local ones. From then on, every Sunday Galician “romerías” were celebrated in the gardens of the big Havana breweries where Galician pies and Ribeiro wine were consumed with melancholy indulgence to the nostalgic sounds of the bagpipes and the merry tunes of the “muñeiras”. In these festive gatherings the identity of the Galician people in the Caribbean exile was revitalized and even created.

    A partir de 1908 el colectivo gallego de Cuba comenzará a organizar las romerías populares de su país de origen. La iniciativa no partió de las grandes sociedades regionales, sino de pequeñas sociedades de adscripción local. Desde entonces todos los domingos se celebraron romerías galaicas en los jardines de las grandes cervecerías habaneras, donde se consumían con melancólica complacencia empanadas y vino del Ribeiro, bajo el nostálgico quejido de las gaitas y los aires festivos de las muñeiras. En este comensalismo festivo se fueron revitalizando, e incluso inventando, las señas de identidad de los gallegos en el exilio caribeño.

    The archaeological researches in Cuba have been oriented mainly to the study of both the eastern and westerns territories of the island: the former province Oriente, considered as the location with the higher density of Agroalfarero communities; and the former provinces of Pinar del Rio, La Havana and Matanzas where mostly Archaic sites have been discovered. However, and in despite of the rich diversity and relevance of the central region of Cuba, this region has been only partially and incompletely studied.

    2010-01-01

    Fascioliasis, an emerging parasitic infection, impacts significantly on both veterinary and human health worldwide. Endemic foci are not limited only to areas of extensive livestock farming, but owing to the parasite's abilities to colonise new intermediate hosts and adapt to new environments, also occur in other places, including Cuba. In Cuba, despite a high prevalence of fascioliasis in livestock, and the widespread occurrence of two potential intermediate hosts, human infection has decreased steadily over the past 10 years. In other parts of the world, human fascioliasis is apparently becoming more frequent. Problems in counteracting the spread of fascioliasis, and approaches used in Cuba to limit zoonotic transmission are discussed, with emphasis on diagnostic and treatment problems, malacological initiatives, and the importance of an integrated control programme. Such programmes may be of benefit in other countries where the prevalence of human fascioliasis is increasing, and lessons may perhaps be learned from the Cuban approach. Copyright 2009 Elsevier Ltd.

    On its deadly run through the Caribbean last September, Hurricane Irma lashed northern Cuba, inundating coastal settlements and scouring away vegetation. Irma lent new urgency to a Cuban national plan, called Tarea Vida, or Project Life, that bans construction of new homes in threatened coastal areas, mandates relocating people from communities doomed by rising sea levels, calls for an overhaul of the country's agricultural system to shift crop production away from saltwater-contaminated areas, and spells out the need to shore up coastal defenses, including by restoring degraded habitat. Project Life stands out for taking a long view: It intends to prepare Cuba for climatological impacts over the next century. Much of the initial funding could come from a $100 million proposal that Cuba plans to submit soon to the Global Climate Fund.

    Foreign investment in the oil and gas sector has had a profound impact on the development of crude oil production in Cuba. In 1982, in order to encourage economic development, the Cuban government adopted a form of Production Sharing Contract (PSC) for international petroleum agreements. In 1990, the first PSC was negotiated with a consortium of European companies. This was followed in 1992 through 1994 with companies from Canada, Europe and Latin America. Then in 1995, a more comprehensive foreign investment law was enacted to further encourage foreign investment in Cuba. Onshore and shallow water regions of Cuba were divided into 45 blocks, 19 of which were under licence in 2001. In addition, in 1999 the government of Cuba offered 53 blocks in the deep water zones of the Cuban sector of the Gulf of Mexico to foreign investment, of which 6 are already under licence. Most exploration for oil and gas since 1991 has been carried out by foreign companies. Crude oil production in 1991 totalled 11,000 bopd of heavy oil production from the north coast of Cuba. By 2001, domestic crude oil production increased to more than 50,000 bopd, mostly due to foreign investment in exploration and development. This paper described the model form for Cuban Production Sharing Contracts with reference to parties, rights granted, terms, relinquishments, minimum exploration commitments, discovery of hydrocarbons and recovery of petroleum operation expenses. The paper also discussed gross production, cost recovery for contractors, and sharing of profits with contractors and the state oil company, CubaPetroleo. 1 fig

    Climate regional characteristics, urban environmental conditions, and outdoors thermal comfort requirements of residents are important for urban planning. Basic studies of urban microclimate can provide information and useful resources to predict and improve thermal conditions in hot-humid climatic regions. The paper analyzes the thermal bioclimate and its influence as urban design factor in Cuba, using Physiologically Equivalent Temperature (PET). Simulations of wind speed variations and shade conditions were performed to quantify changes in thermal bioclimate due to possible modifications in urban morphology. Climate data from Havana, Camagüey, and Santiago of Cuba for the period 2001 to 2012 were used to calculate PET with the RayMan model. The results show that changes in meteorological parameters influence the urban microclimate, and consequently modify the thermal conditions in outdoors spaces. Shade is the predominant strategy to improve urban microclimate with more significant benefits in terms of PET higher than 30 °C. For climatic regions such as the analyzed ones, human thermal comfort can be improved by a wind speed modification for thresholds of PET above 30 °C, and by a wind speed decreases in conditions below 26 °C. The improvement of human thermal conditions is crucial for urban sustainability. On this regards, our study is a contribution for urban designers, due to the possibility of taking advantage of results for improving microclimatic conditions based on urban forms. The results may enable urban planners to create spaces that people prefer to visit, and also are usable in the reconfiguration of cities.

  12. Determinants of mortality transition in developing countries before and after the Second World War: Some evidence from Cuba.

    Díaz-Briquets, S

    1981-11-01

    Few studies provide an insight into what factors contributed to declines in the mortality rates of developing countries before the Second World War. In this paper, statistics on causes of death from Cuba, particularly Havana, are used to investigate what may have been some of the principal determinants of mortality decline in the developing world before the arrival of modern drugs and insecticides. Trends in cause-specific mortality are examined in the light of Cuba's social, economic, medical and public health history. The Cuban experience strongly suggests that in this country public health and sanitary reforms and nutritional improvements were largely responsible for initial declines in mortality throughout the first half of the twentieth century. One important finding is that the impact of these reforms and improved nutrition was greatly influenced by prevailing economic conditions. Periods of economic prosperity facilitated declines in mortality; but in times of adversity, the reverse occurred. It appears that during prosperous periods the maintenance and expansion of public health and sanitary facilities were made possible by increased public and private revenues, and that individuals had access to a more abundant diet. The severe economic crisis of the Great Depression had the opposite effect. With the appearance of sulphonamides in the late 1930s, antibiotics, and residual insecticides and other specific measures at the end of the Second World War, the relevance of economic conditions as a determinant of mortality decline diminished. Although this analysis points to the aforementioned trends, the Cuban experience also suggests that other factors enter into the process of declining mortality and that this phenomenon can only be explained as the result of the complex interplay of many forces.

    A set of samples containing airborne particulate matter (in two particle size fraction PM10 and PM2,5) collected during five months from November 2006 to April 2007 in a urban area of Havana City were analyzed by Particle-Induced X-ray Emission (PIXE) technique and the concentrations of 14 elements (S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Br and Pb) were determined consistently in both particle size fractions with minimum detection limits in the range of ng/m3. A Gent air sampler was used for the aerosol collection in PM10 and PM2,5 particles simultaneously and the PIXE elemental analysis were performed using a proton beam of 2.5 MeV from the 2 MV Van de Graff Tandetron Accelerator at the ININ PIXE Laboratory in Mexico. The analytical database provided by PIXE was statistically analyzed in order to determine the promising local pollution sources. The statistical techniques of Multivariate Factor Analysis in combination with the Principal Component Analysis methods were applied to this data and allowed identifying five main pollution sources of airborne particulate matter (PM10 and PM2,5) collected in this area. The main (local) identified sources were: soil dust, sea spray, industry, fossil fuel combustion from motor vehicles and burnings or incinerations of diverse materials. A general discussion about these results is presented in this work. (Author)

    Full Text Available Over the past 10 years, the American Region has witnessed the reintroduction and dissemination of dengue virus serotype 3. In this paper we describe the main clinical and epidemiologic features of the dengue 3 epidemic that broke out in Cuba between June 2001 and March 2002, as well as the measures that were undertaken to eliminate it. A total of 14 524 confirmed cases were reported, 12 889 (88,7% of them in the City of Havana. Eighty-one cases of dengue hemorrhagic fever were confirmed, three of which died. Secondary infection, white skin color, sickle cell anemia, and bronchial asthma were risk factors for dengue hemorrhagic fever. Active clinical and epidemiologic surveillance and laboratory support were critical to the early detection of transmission and to the monitoring of the epidemic. Widespread involvement of the community and its different sectors, participation of the mass media with a single leadership in command, and strong political will were the key factors that made it possible to eliminate transmission. This epidemic was one more example of the risk of dengue epidemics faced by countries in the area, including those that have strong surveillance and control programs. It also served to show that by applying the principles established by the Pan American Health Organization and the World Health Organization for dengue control, transmission can be stopped.

    INTRODUCTION Leprosy, an infectious disease caused by Mycobacterium leprae, affects the nervous system, skin, internal organs, extremities and mucous membranes. Biological, social and environmental factors influence its occurrence and transmission. The first effective treatments appeared in 1930 with the development of dapsone, a sulfone. The main components of a control and elimination strategy are early case detection and timely administration of multidrug therapy. OBJECTIVES Review the history of leprosy control in Cuba, emphasizing particularly results of the National Leprosy Control Program, its modifications and influence on leprosy control. EVIDENCE ACQUISITION The historiological method was applied using document review, complemented by interviews with experts on leprosy and its control. Archived documents, medical records, disease prevalence censuses conducted since 1942, and incidence and prevalence statistics for 1960-2015 from the Ministry of Public Health's National Statistics Division were reviewed. Reports and scientific literature published on the Program and the history of leprosy in Cuba were also reviewed. DEVELOPMENT Leprosy has been documented in Cuba since 1613. In 1938, the Leprosy Foundation was created with ten dispensaries nationwide for diagnosis and treatment. The first National Leprosy Control Program was established in 1962, implemented in 1963 and revised five times. In 1972, leper colonies were closed and treatment became ambulatory. In 1977, rifampicin was introduced. In 1988, the Program instituted controlled, decentralized, community-based multidrug treatment and established the criteria for considering a patient cured. In 2003, it included actions aimed at early diagnosis and prophylactic treatment of contacts. Since 2008, it prioritizes actions directed toward the population at risk, maintaining five-year followup with dermatological and neurological examination. Primary health care carries out diagnostic and treatment

    the integration of chemical and biological methods is one of the strategies for the vector control, due to the existing environmental problems and the concerns of the community as a result of the synthetic organic insecticide actions. The bacterium called Bacillus thuringiensis var. israelensis in liquid formulation has been widely used in the vector control programs in several countries and has shown high efficacy at lab in Cuba. to determine the susceptibility of Aedes aegypti collected in the municipalities of La Habana province to Bacillus thuringiensis var. israelensis. fifteen Aedes aegypti strains, one from each municipality, were used including larvae and pupas collected in 2010 and one reference strain known as Rockefeller. The aqueous formulation of Bacillus thuringiensis var. israelensis (Bactivec, Labiofam, Cuba) was used. The bioassays complied with the World Health Organization guidelines for use of bacterial larvicides in the public health sector. The larval mortality was read after 24 hours and the results were processed by the statistical system SPSS (11.0) through Probit analysis. the evaluated mosquito strains showed high susceptibility to biolarvicide, there were no significant differences in LC50 values of Ae. aegypti strains, neither in the comparison of these values with those of the reference strain. the presented results indicate that the use of Bacillus thuringiensis var. israelensis continues to be a choice for the control of Aedes aegypti larval populations in La Habana province.

    Petroleum generation in the North Cuba Basin is primarily the result of thrust loading of Jurassic and Cretaceous source rocks during formation of the North Cuba fold and thrust belt in the Late Cretaceous to Paleogene. The fold and thrust belt formed as Cuban arc-forearc rocks along the leading edge of the Caribbean plate translated northward during the opening of the Yucatan Basin and collided with the passive margin of southern North America in the Paleogene. Petroleum fluids generated during thrust loading migrated vertically into complex structures in the fold and thrust belt, into structures in the foreland basin, and possibly into carbonate reservoirs along the margins of the Yucatan and Bahama carbonate platforms. The U.S. Geological Survey (USGS) defined a Jurassic-Cretaceous Composite Total Petroleum System (TPS) and three assessment units (AU)-North Cuba Fold and Thrust Belt AU, North Cuba Foreland Basin AU, and the North Cuba Platform Margin Carbonate AU-within this TPS based mainly on structure and reservoir type (fig. 1). There is considerable geologic uncertainty as to the extent of petroleum migration that might have occurred within this TPS to form potential petroleum accumulations. Taking this geologic uncertainty into account, especially in the offshore area, the mean volumes of undiscovered resources in the composite TPS of the North Cuba Basin are estimated at (1) 4.6 billion barrels of oil (BBO), with means ranging from an F95 probability of 1 BBO to an F5 probability of 9 BBO; and (2) 8.6 trillion cubic feet of of gas (TCFG), of which 8.6 TCFG is associated with oil fields, and about 1.2 TCFG is in nonassociated gas fields in the North Cuba Foreland Basin AU.

    Full Text Available It was carried out a descriptive, retrospective and longitudinal study of the medical records of 245 people who have been diagnosed as having HIV-aids and who have been treated at the municipal decentralization office of Centro Havana from January 2006 through June 2008. The study was aimed at making a characterization of the office. The statistical analysis consisted on the calculation of the absolute and relative frequencies of each of the variables under study, using the SPSS statistical package, version 11.5. The study revealed that the highest percentage of patients was between 20 to 39 years old, in both sexes, with a prevalence of people who have completed either secondary or pre-university education. 60 % are retired, 60. 4% live crammed and the majority of them live on houses in regular or bad conditions. 72,6% of the studied group has a homosexual orientation. Based on the HIV and aids classification, 149 were diagnosed as having HIV. The studied group of highest incidence was the one selected. 99% became infected via sexual transmission. The more frequent unhealthy habit was a sedentary lifestyle. The most frequently reported side effect of the three-therapy treatment was the hyperlipidemia. The most prevalent opportunist infectious disease was Pneumonia by Pneumocistis Carini. Depressive neurosis was the main diagnosis at the medical office, while the most prevalent non-transmissible chronic disease was hypertension. Fourteen patients have died; 1873 consultations and 674 home visits have been made. We recommend that a medical multidisciplinary team be put together at the HIV-AIDS office, and that a plan of action will be created to solve the detected problems.

There were not significant differences in microalgal diversity in the water column in the two locations. In both locations, the diatoms had the largest number of species and individuals in stomachs and water. In Santa Fe, dinoflagellate biomass was larger in water and stomach contents, while in Punta del Este the contribution of each group to the stomach content was similar to that of the water column. This species filters in a constant and

    Plagued by many years of frequent leadership changes, and influences from power brokers whose policies and politics were oftentimes detrimental to Cuba's emerging as an industrialized and diverse economy nation, Cuba is now attempting to move beyond the survival mode. After the symbiotic relationship between the Soviet Union was dismantled in the 90s, Cuba is now undergoing metamorphoses of growth and change, socially, politically and culturally, while still remaining a mixture of worlds both rural and urban. This narrative article describes the multicultural experiences that an American university professor recently experienced while visiting Cuba.

  10. Four decades of kidney transplantation in Cuba.

    This article describes the background, beginnings, development, evolution and outcomes of kidney transplantation in Cuba. Nephrology as a medical specialty in Cuba began in 1962 and was formalized in 1966. Conditions were created to implement renal replacement therapy (including transplants), bring nephrology care to the entire country and train human resources who would assume this responsibility, making Cuba one of the first countries with a comprehensive program for renal patient care. After three unsuccessful cadaveric-donor kidney transplantations in 1968-69, the ensuing history of kidney transplantation can be summarized in the following three stages. 1970-1975: In January 1970, cadaveric-donor kidney transplantation began at the Nephrology Institute. That year, 17 kidney transplantations were performed; four of these patients lived with functional kidneys for 15-25 years; 10-year graft survival was 23.5% (Kaplan-Meier survival curve); HLA typing began in 1974. By December 1975, 170 grafts had been done in three hospitals. 1976-1985: Seven transplantation centers performed 893 grafts during this period. HLA-DR typing was introduced in 1976 and the National Histocompatibility Laboratory Network was founded in 1978. The first related living-donor kidney transplantation was done in 1979. 1986-2011: The National Kidney Transplantation Coordinating Center and the National Kidney Transplantation Program were created in 1986; the first combined kidney-pancreas transplantation was performed the same year. In 1990, cyclosporine and the Cuban monoclonal antibody IOR-T3 were introduced for immunosuppression to prevent rejection, as were other Cuban products (hepatitis B vaccine and recombinant human erythropoietin) for transplant patients. By December 2011, the cumulative number of transplants was 4636 (384 from related living donors). With over 40 years of experience, kidney transplantation is now well established in Cuba; it is free and universally accessible, on the

    The lack of drinking water has become a problem at world level because, in many places, supplies are very limited and, in other places, their reserves have been drained. At the present time there are estimated to be around two thousand million people that don't have drinking water for several reasons, such as drought, contamination and the presence of saline waters not suitable for human consumption. Because of the human need for water, they have always taken residence in areas where the supply was guaranteed, sometimes impeding the exploitation of other areas that can be economically very interesting. However, this resource is usually very close and in abundance in the form of seawater but its salinity makes it unusable for many basic requirements. Humanity has been forced, therefore, to take into consideration the possibilities of the economic treatment of seawater. Cuba has regions where the supplies of drinking water are scarce and others where the lack of this resource limits economic exploitation. The present work is approached with regard to the situation of hydro resources in Cuba, it includes: a description of the main hydrographic basins of the country; the contamination levels of the waters and the measures for mitigation; analysis of the supplies and demand for drinking water and its quality; regulatory aspects. The state of seawater desalination in Cuba is also included and the possibility of its realisation using nuclear energy and the advantages that this would bring is evaluated. (author)

    Full Text Available Invasive Meningococcal Disease (IMD is a worldwide health problem. In Cuba, vaccination against meningococcal B-C has been carried out since 1989. The study aimed at describing the epidemiology of IMD in Cuba from 1983 to 2006 and at contributing to the immunization strategy. A descriptive and analytical study was carried out. Epidemiological data was obtained from the National Surveillance System at the Institute "Pedro Kourí". More than 1 000 cases were reported in 1986 and the overall incidence was above 10/100 000 inhabitants. Since 1989 a remarkable and continuous decline in the incidence was observed. In the last nine years a strong association of IMD to boarding school students (OR=9.4; confidence interval 95%: 5.1-17.4, recluses (OR=5.9; CI 95%: 1.5 -24.3 and day students (OR=3.9; CI 95%: 2.8-5.6 was observed. Housewife (OR=4.9; CI 95%: 1.9-12.4 and pensioned (OR=4.5; CI 95%: 1.2-16.8 showed association with mortality. Previous vaccination was a protective factor against morbidity (OR=0.6; CI 95%: 0.4-1.0 and mortality (OR=0.4; CI 95%: 0.2-0.9 by IMD. Neisseria meningitidis B4:P1.15 was the main circulating strain. Incidence of IMD declined markedly in Cuba by using group BC strain-specific meningococcal vaccine.

    Human toxocariasis (HT) is a zoonotic disease caused by infection with the larval stage of Toxocara canis, the intestinal roundworm of dogs. Infection can be associated with a wide clinical spectrum varying from asymptomatic to severe organ injury. While the incidence of symptomatic human toxocariasis appears to be low, infection of the human population is widespread. In Cuba, a clear overview on the status of the disease is lacking. Here, we review the available information on toxocariasis in Cuba as a first step to estimate the importance of the disease in the country. Findings are discussed and put in a broader perspective. Data gaps are identified and suggestions on how to address these are presented. The available country data suggest that Toxocara infection of the definitive dog host and environmental contamination with Toxocara spp. eggs is substantial, but information on HT is less conclusive. The availability of adequate diagnostic tools in the country should be guaranteed. Dedicated studies are needed for a reliable assessment of the impact of toxocariasis in Cuba and the design of prevention or control strategies. PMID:22389726

    In this paper the main results obtained in the use of lichens as bio monitors to estimate the levels of atmospheric deposition of Al, Br, Ca, Cd, Co Cr, Cu, Fe, Mg, Mn, Na is short, Ni, Pb , Sr, V and Zn in Havana during the period 2001-2010 are shown. For the determination of the elemental contents were used and evaluated the possibilities of X-ray fluorescence, atomic absorption spectrophotometry, Polarography (voltammetry stripping anode) Atomic Emission Spectrometry with Inductively coupled plasma and mass spectrometry Inductively Coupled Plasma. The simultaneous application of three methods in the case of some chemical elements also allowed to make comparisons of the results, which is important from the point of view of quality assurance. It is also significant that the analytical techniques used in this work are available in the country, so that this experience could be used by other institutions for this kind of studies. A comparative study of three species of lichens is reported and Physcia alba has being selected as the most suitable dawn. The spatial and temporal diagrams of the elements studied in the territory of the Capital and its relation to the main sources of pollution distribution are established. The study of isotopic ratios for lead allowed to confirm that the source of atmospheric Pb in Havana is a possible mixture of soil dust and anthropogenic activities such as the combustion of domestic heavy oil used for power generation and other industries.

    analyze home care services in Cuba and determine how length of stay, per-day cost, and per-patient cost vary by diagnosis and by the area of the country in which the services are rendered. METHODS: Patient information was analyzed for 837 individuals who were enrolled in home care services between July 2001 and June 2002 in the following four municipalities: (1 Playa municipality (a metropolitan urban area in the province of the City of Havana; Cruces municipality (an urban, but not metropolitan, area in the province of Cienfuegos; Unión de Reyes municipality (a rural area in the province of Matanzas; and Fomento municipality (a mountainous rural area in the province of Sancti Spiritus Analysis of the mean length of stay for home care services was conducted using the Kaplan-Meier survival curve method. The impact of the following criteria on the probability and timing of discharge was also assessed: diagnosis at time of enrollment (respiratory, gastrointestinal, obstetrical/gynecological, hospital discharge follow-up, and other causes, area in which services were rendered, and patient gender and age. The total service, per-patient, and per-day costs were determined for each municipality. Adjusted multilinear regression models were used to determine how length of stay, diagnosis upon enrollment, and service area affected cost. RESULTS: The diagnoses most frequently requiring home care were respiratory illness (31.4%, hospital follow-up of acute condition (15.5%, obstetrical/ gynecological illness (10.8%, and gastrointestinal disorder (8.1%. The mean length of stay was 6 days (95% confidence interval: 5.75 to 6.25. In Fomento, the probability of patients enrolling in home care was 66% lower than in Cruces and 30% lower than in Playa and Unión de Reyes. The total direct cost of home care in the municipalities studied ranged, in Cuban pesos, from $3 983.54 to $9 624.87. The per-day cost ranged from $2.57 to $6.88, and the per-patient cost from $23.04 to $42.78. The length

    Full Text Available Una vez concluida la segunda intervención militar norteamericana en 1909 y como parte del esfuerzo del gobierno cubano para proyectar una imagen de renacer republicano, a partir del curso 1910-1911 se pusieron en vigor los primeros estatutos universitarios redactados sin la presencia de autoridades colonialistas ni de gobiernos interventores en Cuba. Desde entonces vivió la Universidad hasta 1921 en un ambiente de cierta normalidad, aunque se fue convirtiendo en fiel reflejo del estado de corrupción que se había generalizado en casi todas las esferas del quehacer político y administrativo del país. El agravamiento de esa actuación y la actitud indigna de una gran parte de los profesores y autoridades universitarias, aceleró la toma de conciencia del estudiantado cubano y desencadenó una crisis que alteró por completo la vida académica en la Universidad de La Habana. Se presenta un breve resumen de lo acontecido en la mencionada institución y, particularmente, en su Escuela de Farmacia entre los cursos 1910-1911 y 1920-1921.After the end of the second US military intervention in 1909, the Cuban government made efforts to exhibit an image of republican rebirth and, as a result, the first university statutes, which were drafted without the supervision of either colonial or interventionist governments, were put into effect in the 1910-1911 academic course. Since then, the University carried out its activities in a quite normal environment until 1921, although it also was an exact reflection of the corruption existing in almost every political and administrative sphere of the country. The worsening of this situation and the outrageous attitude of many university professors and authorities made the Cuban students be more aware of this state of affairs and unleashed a crisis that fully changed the academic life of the University of Havana.

    In Cuba, antiretroviral therapy rollout started in 2001 and antiretroviral therapy coverage has reached almost 40% since then. The objectives of this study were therefore to analyze subtype distribution, and level and patterns of drug resistance in therapy-naive HIV-1 patients. Four hundred and one plasma samples were collected from HIV-1 therapy-naive patients in 2003 and in 2007-2011. HIV-1 drug resistance genotyping was performed in the pol gene and drug resistance was interpreted according to the WHO surveillance drug-resistance mutations list, version 2009. Potential impact on first-line therapy response was estimated using genotypic drug resistance interpretation systems HIVdb version 6.2.0 and Rega version 8.0.2. Phylogenetic analysis was performed using Neighbor-Joining. The majority of patients were male (84.5%), men who have sex with men (78.1%) and from Havana City (73.6%). Subtype B was the most prevalent subtype (39.3%), followed by CRF20-23-24_BG (19.5%), CRF19_cpx (18.0%) and CRF18_cpx (10.3%). Overall, 29 patients (7.2%) had evidence of drug resistance, with 4.0% (CI 1.6%-4.8%) in 2003 versus 12.5% (CI 7.2%-14.5%) in 2007-2011. A significant increase in drug resistance was observed in recently HIV-1 diagnosed patients, i.e. 14.8% (CI 8.0%-17.0%) in 2007-2011 versus 3.8% (CI 0.9%-4.7%) in 2003 (OR 3.9, CI 1.5-17.0, p=0.02). The majority of drug resistance was restricted to a single drug class (75.8%), with 55.2% patients displaying nucleoside reverse transcriptase inhibitor (NRTI), 10.3% non-NRTI (NNRTI) and 10.3% protease inhibitor (PI) resistance mutations. Respectively, 20.7% and 3.4% patients carried viruses containing drug resistance mutations against NRTI+NNRTI and NRTI+NNRTI+PI. The first cases of resistance towards other drug classes than NRTI were only detected from 2008 onwards. The most frequent resistance mutations were T215Y/rev (44.8%), M41L (31.0%), M184V (17.2%) and K103N (13.8%). The median genotypic susceptibility score for the

    Setting up quality management systems in nuclear medicine in Cuba has been an aim for medical physicists. In the last decade, we have walked with steady steps towards that direction, by setting up national standards and regulations, and carrying out research projects in order to ensure the improvement of quality assurance and management programs. In 2010 the IAEA's QUANUM document has been applied, as a methodology for quality management audits in nuclear medicine. Five audits have shown that most of class A regulatory items are guaranteed at nuclear medicine services. However, quality management system performing is still inappropriate. (Author) 13 refs.

    Abstract Objective Low birthweight is associated with a decreased risk of childhood leukemia and an increased risk of both cardiovascular disease and all‐cause mortality in adult life. Possible biological mediators include systemic innate immunity and inflammation. We tested the hypothesis that birthweight was inversely associated with serum high sensitivity C reactive protein assay (hsCRP), a measure of both innate immunity and systemic inflammation. Methods Data on birthweight and current anthropometric measures along with a range of exposures were collected at 1 and 3 years of age in a population‐based cohort study of young children living in Havana, Cuba. A total of 986 children aged 3‐years‐old provided blood samples that were analyzed for serum hsCRP levels. Results Nearly 49% of children had detectable hsCRP levels in their serum. Lower birthweight was linearly associated with the natural log of hsCRP levels (beta coefficient −0.70 mg L−1 per kg increase in birthweight, 95% CI: −1.34 to −0.06). This was attenuated but still present after adjustment for the child's sex and municipality (−0.65 mg L−1 per kg birthweight; 95% CI: −1.38 to +0.08). There were no associations between growth from birth or anthropometric measures at 3 years and systemic inflammation. Conclusions Birthweight was inversely associated with serum hsCRP levels in children aged 3 years living in Cuba. These observations provide a potential mechanism that is present at the age of 3 years to explain the association between low birthweight and both decreased childhood leukemia and increased cardiovascular disease in adults.

    1990-02-01

    The Cuban oil industry started in 1860 when an oil well was drilled in Matanzas province. About 200 wells were drilled up until 1959. In the past 30 years, the oil industry has become a priority sector; in 1985-1990, about US$500 million were invested in the industry, with increases in exploration and well drilling activity. Recently completed works include pipelines and a supertanker terminal. About 10 million tons of oil are imported annually and local production averages about 800,000 metric tons per year. Most of the oil found in Cuba so far is of the heavy type, as found in western Canada. There are about 10 small and medium-sized oil deposits, mainly located in the north. The most promising oil field is at Varadero, whose characteristics are similar to the Cold Lake field in Alberta. Cuban oil refining capacity is over 7.6 million metric tons per year, and additional capacity is being constructed. All imports of oil industry equipment are conducted via state trading agencies. Export opportunities of interest to Canadian companies are outlined, along with monetary constraints affecting imports to Cuba, financing and export insurance programs available to Canadian companies, and recommendations to Canadian exporters. A list of industry/government contacts is included

    í como entre de las distintas fechas de muestreo. El análisis de variancia bifactorial no mostró interacción significativa espacio-tiemporal. Malecón, sitio más contaminado, presentó menor reclutamiento y mayor presencia de especies consideradas indicadoras de contaminación orgánica, sedimentación y abrasión. Las densidades fueron mayores en Octubre 2007 y menores en Mayo 2008, al parecer influenciados por las épocas de reproducción y la acción de los frentes fríos respectivamente. El mayor predominio y abundancia de reclutas de S. siderea, S. radians y P. astreoides parece responder a sus elevados potenciales reproductivos y altas resistencias a disturbios. La identidad de las especies dominantes estuvo relacionada aparentemente con las distancias de las principales fuentes de contaminación. Se recomienda replicar esta investigación en otros lugares de la región del Caribe para probar la generalidad de estos resultados. Estudios futuros debieran tener en cuenta la influencia de otros factores ambientales, junto con una valoración de la tolerancia de las especies de reclutas a estos factores, para ponderar mejor el efecto de la contaminación urbana sobre el reclutamiento.The effect of pollution on coral recruitment has been insufficiently studied. This research deals with coral recruitment in coastal areas and aimed to determine the variations of density and dominant species of corals recruits in sites at different distances from pollution sources. The composition and structure of stony coral (scleractinian and milleporids recruit associations were characterized in the fringing reef of Western Havana, Cuba. This reef is influenced by urban pollution from the Almendares River and a sewage outlet located at its mouth. Four sites were sampled on the upper fore reef escarpment at 10m deep every three months between July 2007 and May 2008. A 25cm side quadrat was used to determine the density and taxonomic composition of recruits smaller than 3cm in

    Consistent with the limited dispersal capacity of most troglobitic animals, almost all Lucifuga cavefish species have very narrow geographic distribution in Cuba. However, one species, L. dentata, has a wide but disjointed distribution over 300 km in the west of the island. In order to estimate the relative role of vicariance and dispersal in the unexpected L. dentata distribution, we obtained partial sequences of the mitochondrial DNA (mtDNA) cytochrome b (cytb) gene and control region (CR), and then applied Approximate Bayesian Computation (ABC), based on the identification of five genetic and geographic congruent groups of populations. The process that best explains the distribution of genetic diversity in this species is sequential range expansion from east Matanzas to the western Pinar del Río provinces, followed by isolation of groups of populations. We found relative high haplotype diversity and low nucleotide diversity in all but the Havana group, which has high values for both diversity parameters, suggesting that this group has been demographically stable over time. For two groups of populations (Cayuco and Bolondrón), the mismatch distribution analyses suggests past demographic expansion. In the case of the Cayuco region, the star like relationships of haplotypes in the network suggests a recent founding event, congruent with other evidence indicating that this is the most recently colonized region. Over all, the results suggest that a combination of habitat availability, temporal interconnections, and possibly the biological properties of this species, may have enabled its dispersal and range expansion compared to other species of the genus, which are more geographically restricted.

    There is a concern that allergic disease in childhood is higher than expected in Cuba. The aim of this study was to determine the risk factors for eczema of infants aged 12-15 months living in Havana. We used a cross-sectional epidemiological study design. Data on eczema symptoms and a wide range of lifestyle factors were collected by researcher administered questionnaires. Data were collected on 1956 children (96% response rate), of whom 672 (34%) were reported as having had eczema. Independent risk factors for eczema included young maternal age (adjusted odds ratio (OR) 0.98 per additional year of age; 95% confidence interval (CI) 0.97-0.99), child's weight (OR 1.13 per additional kg; 95% CI: 1.03-1.25), insect sting allergy (OR 2.11; 95% CI: 1.33-3.35), rodents in the home (OR 1.39; 95% CI: 1.10-1.76), attendance at childcare facilities (OR 1.34: 95% CI: 1.05-1.70) and self-reported mould in the home (OR 1.23; 95% CI: 1.07-1.41). Infant exposure to paracetamol was associated with an increased risk of eczema even after adjustment for wheeze (OR 1.22; 95% CI: 1.03-1.46). Despite a very different culture and environment, the consistency of these findings with those from more economically developed countries suggests potential causal associations. The association with paracetamol, even after adjustment for wheeze, suggests that intervention studies are required in young infants, to ascertain if this commonly used anti-pyretic medication increases allergic disease.

    2017-01-01

    While Cuba enjoys a high rate of electrification, 82% of its electricity today is generated from oil with an overall estimated levelized cost of energy (LCOE) of $0.27 per kWh. Moreover, Cuba is experiencing increased electricity demand driven by a burgeoning tourism industry and an emerging small-medium size business sector. If the current power mix persists until 2040, power generation costs and carbon emissions would nearly double to US$9.8B and 24M MT CO2 per year respectively. This paper presents an overall strategy for Cuba to ensure its energy security and provide the Cuban people with clean, affordable and reliable access to electricity. With a total estimated cost of $14.1B, our proposal aims to reduce the overall cost of electricity generation to $0.14 per kWh by 2040. We recommend: Implementing a comprehensive renewable energy strategy that includes an energy mix of: (1) community-solar for small cooperative business (8.5%); (2) long-term investments for utility-scale solar IPPs (8.5%); (3) development of wind farms by IPPs (17.5%); and (4) maintaining supplementary biomass generation (6%); Installing complementary reliable sources of grid power from natural gas combined cycle plants (NGCC) via domestic production and LNG imports from a floating storage regasification unit (FSRU), accounting for 35% of Cuba’s energy; Attracting $700 million in infrastructure investment necessary to decrease transmission and distribution (T&D) losses; and Enacting reforms that increase regulatory certainty, investor protection, and the ease of doing business in Cuba for foreign investors.

    Specimens of the gorgonian Plexaura homomalla were sampled from several areas along the fringing reefs fronting the United States Naval Base at Guantánamo Bay, Cuba. Sample coverage extended from apparently healthy reefs in oceanic waters to declining reefs located in the plume of the drainage from upper parts of Guantánamo Bay. Tentacle tips were excised, and trunk sections were cut and polished. Stable isotope ratios of nitrogen (δ 15 N) and carbon indicate a strong correlation of reef health with proximity to the plume of the river. Of all the worldwide cases in which land-based sources of pollution have impacted reefs, this one may well be the most intractable. The US Navy has jurisdiction over the reefs, with the obligation to protect them, yet the threat comes down the river from Cuba

    Full Text Available Cuba's Transfusion Medicine Program (TMP is a subsystem of the country's National Health System. The TMP's objective is to ensure hemotherapy with blood that is safe and sufficient for all the individuals who need it. The TMP subsystem is made up of the National Commission on Transfusion Medicine, the Institute of Hematology and Immunology, 37 clinical services, 44 blood banks, 120 collection centers, 19 mobile units, and 37 blood certification laboratories. Additional facilities include a laboratory for plasma separation, a laboratory that produces leukocyte interferon and transfer factor, and two laboratories that produce reagents for blood classification and blood diagnosis systems. In Cuba, blood donation is voluntary. Since 1997 approximately 5% of the population per year has donated blood, thus meeting the goal recommended by the Pan American Health Organization of one voluntary blood donation annually for every 20 persons. During 2002, 563 204 blood donations were received, and there were 445 898 transfusions of blood or blood components. All donations are individually screened for HIV 1 and 2, hepatitis B, hepatitis C, and syphilis, thus meeting the country's current regulations. In 2002 these screening measures led to discarding, respectively, 0.12%, 0.60%, 0.71%, and 1.8% of the blood donations. Although the prevalence of human T-cell lymphotropic virus I and II in Cuba is very low, this test will soon be added to the screening process.

    2001-01-01

    Full Text Available This artide evaluates the Cuba Company’s impact on eastern Cuban economic development. It argues that the Cuba Company’s railroads, together with its development plans and strategies, helped stimulate the extraordinary economic growth of eastern Cuba between 1900 and 1959, especially in the production of sugar. Sugar was king in Cuba before 1900 but only inwestern Cuba; eastern Cuba produced only a minuscule fraction of total Cuban sugar production. Moreover, the Cuban Independence War of 1895-1898 had destroyed the industry. Due to the Cuba Company’s strategy, however, by the 1920s Cuba was once again the largest producer of sugar in the world and eastern Cuba represented over 50% of total Cuban sugarproduction.

    The appearing of the problem for protecting the environment from radioactive contamination is not an accidental matter. The introduction into the earth crust of radioactive material coming from nuclear weapons, accidents, wastes, etc, has caused, as a consequence, the contamination of the biosphere. The extensive trade of food in our country has made necessary the establishment of radiological monitoring in food, which was organized by the Department of Public Health. The structure, functions, characteristics and aspects related to radiological monitoring of food in Cuba are shown in the present paper.

    Abstract The production and use of Ra-226 sealed sources was internationally recommended to be halted for health and safety reasons. Consequently, all Ra-226 sources in Cuba were collected, characterized and conditioned. The paper describes the safety and operational aspects related to the Ra-226 conditioning. For this, a Special Permission was granted by the Regulatory Body, as required. A radiological assessment, a safety report as well as an emergency plan were prepared and approved before the operations. The work was accomplished with due reliability following an established comprehensive Quality Management System. As a result of these operations, 188.5 GBq of Ra-226, contained in different types of radiation sources (brachytherapy needles and tubes, standard sources for calibration, etc.) were encapsulated and conditioned. The capsules with the sources were conditioned in a retrievable form within fi ve waste packages intended for long term storage.(author)

    Communicating astronomy with the public to produce attractive materials for a broad audience on TV is a difficult job in a third world country. One way of developing effective communication in fields like astronomy, astrophysics, and cosmology whilst connecting the professional astronomer with a majority of the people is to combine the knowledge of the scientist with the most spectacular TV production methods of first world countries: integrating, through commentary and analysis, astronomy and science into the public debate of lay citizens. Here I present my ten years of experience of presenting a TV programme devoted to general science outreach. I also comment on the progress of the construction of the new planetarium, a cultural centre for science and technology, to be opened as part of the commemoration activities for the 2009 International Year of Astronomy. It is hoped to guide the interest of the people of Cuba towards basic science and astronomy in the most populated and frequented area of the country.

  10. Birth planning in Cuba: a basic human right.

    Science.gov (United States)

    Swanson, J M

    1981-01-01

    This paper reports on the development of birth planning in Cuba and strategies that are relevant to nurses in the communities of Cuba. Cuba reduced its crude birth rate by 40% from 1964-75 without formal family planning programs and resources. By 1975, Cuba had achieved the lowest birth rate in Latin America (21/1000) except Barbados (19/1000). By 1978, Cuba's crude birth rate declined to a low of 15.3/1000. The demographic transition in Cuba has been a process of equalization by: 1) community participation to ensure basic human rights for everyone, 2) increasing the status of women while providing child care centers, 3) providing equal availability of health care services including contraceptive services, sterilization, and abortion, and 4) focusing on individual birth choice, not on limiting population growth. Emphasis in Cuba for reducing fertility has been put on literacy, education, and infant mortality. The illiteracy rate in 1961 decreased from 20% to 4%. Infant mortality decreased from 38.8/1000 live births in 1970 to 22.3/1000 in 1978. 1/3 of Cuban women were participating fully in the labor force in 1978. Polyclinics have been established as preventive care medical centers throughout Cuba and health care is free. Family planning options are integrated into routine primary health care at polyclinics and assure equal access to the total Cuban population. Abortion is freely available and increased to 61/1000 in 1976. The implications for nursing are that: 1) the traditional work of nurses places them in a key position to help extend basic human rights beyond current levels, 2) nurses can initiate discussions of birth planning with women and men in a variety of settings, and 3) nurses can increase case-finding related to birth planning needs both in health care classes or within established groups in the community.

  14. Baculovirus potential for agricultural pests management in Cuba

    Jorge Luis Ayala Sifontes

    2017-10-01

    Full Text Available Cuba has an international reputation for implementing widespread biological control of pests, and microbial biocontrol is an integral component of most pest management programs. One class of microbial pesticides however, has not been developed in Cuba, bio-insecticides based on the Baculoviridae. This class of safe and environmentally protective microbial pesticides is used ever more commonly worldwide as an alternative to chemical pesticides. The characteristics of the viruses of this family, particularly their high host specificity, safety to non-target organisms, capacity to persist in nature and create epizootics, and the economy with which they can be produced "in vivo", all make them attractive for incorporation into pest management programs along with other pesticides developed in Cuba. The mass production technology is well understood in Cuba and biofactories already exist for a number of microbial biocontrol products. In the province of Sancti Spíritus, the Plant Protection Laboratory of the Ministry of Agriculture, with the cooperation of the Institute for Sustainable Horticulture, Kwantlen Polytechnic University, are resuming the work which began in the 90´s to develop baculovirus products in support of sustainable agriculture in Cuba. This work is being carried out with the participation of young Canadian and Cuban students and professionals. The program includes research with the multicapsid nuclear polyhedrosis viruses of Spodoptera frugiperda (SfMNPV and S. exigua (SeMNPV and the search for native isolates of Baculovirus in Plutella xylostella, three priority pests in Cuba. In other jurisdictions they are well controlled by baculoviruses, and the expectation is that this same result is possible in Cuba.

    Setting up quality management systems in nuclear medicine in Cuba has been an aim for medical physicists. In the last decade, we have walked with steady steps towards that direction, by setting up national standards and regulations, and carrying out research projects in order to ensure the improvement of quality assurance and management programs. In 2010 the IAEA's QUANUM document has been applied, as a methodology for quality management audits in nuclear medicine. Five audits have shown that most of class A regulatory items are guaranteed at nuclear medicine services. However, quality management system performing is still inappropriate. (Author) 13 refs.

  17. Parameterized equation for the estimation of the hydraulic conductivity function not saturated in ferralsols south of Havana

    International Nuclear Information System (INIS)

    González Robaina, Felicita; López Seijas, Teresa

    2008-01-01

    The modeling of the processes involved in the movement of water in soil solutions generally requires the general equation of water flow for the condition of saturation, or Darcy - Buckinghan approach. In this approach the hydraulic - soil moisture (K(0)) conductivity function is a fundamental property of the soil to determine for each field condition. Several methods reported in the literature for determining the hydraulic conductivity are based on simplifications of assuming unit gradient method or a fixed ratio K(0). In recent years related to the search for simple, rapid and inexpensive methods to measure this relationship in the field using a lot of work aftershocks reported. One of these methods is the parameterized equation proposed by Reichardt, using the parameters of the equations describing the process of internal drainage and explain the exponential nature of the relationship K(0). The objective of this work is to estimate the K(0), with the method of the parameterized equation. To do the test results of internal drainage on a Ferralsol area south of Havana will be used. The results show that the parameterized equation provides an estimation of K(0) for those similar to the methods that assume unit gradient conditions

    1992-09-01

    In 1976, the Soviet Union and Cuba concluded an agreement to construct two 440-megawatt nuclear power reactors near Cienfuegos on the south central coast of Cuba, about 180 miles south of Key West, Florida. The construction of these reactors, which began around 1983, was a high priority for Cuba because of its heavy dependence on imported oil. Cuba is estimated to need an electrical generation capacity of 3,000 megawatts by the end of the decade. When completed, the first reactor unit would provide a significant percentage (estimated at over 15 percent) of Cuba's need for electricity. It is uncertain when Cuba's nuclear power reactors will become operational. On September 5, 1992, Fidel Castro announced the suspension of construction at both of Cuba's reactors because Cuba could not meet the financial terms set by the Russian government to complete the reactors. Cuban officials had initially planned to start up the first of the two nuclear reactors by the end of 1993. However, before the September 5 announcement, it was estimated that this reactor would not be operational until late 1995 or early 1996. The civil construction (such as floors and walls) of the first reactor is currently estimated to be about 90 percent to 97 percent complete, but only about 37 percent of the reactor equipment (such as pipes, pumps, and motors) has been installed. The civil construction of the second reactor is about 20 percent to 30 percent complete. No information was available about the status of equipment for the second reactor. According to former Cuban nuclear power and electrical engineers and a technician, all of whom worked at the reactor site and have recently emigrated from Cuba, Cuba's nuclear power program suffers from poor construction practices and inadequate training for future reactor operators. One former official has alleged, for example, that the first reactor containment structure, which is designed to prevent the accidental release of radioactive material into

En 1722 aparece el término Pediatría en la Europa Central, y en 1865, por primera vez, es acuñado el término Puericultura por Alfred Pierre Caron, profesor en la Universidad de París. Realizar consultas de Puericultura en la primera mitad del siglo XX en Cuba era prácticamente un lujo. Con el sistema único de salud y cobertura total de la atención primaria a partir de 1959, se lograron establecer consultas de Pediatría (1960 y Puericultura (1963 en los policlínicos. El nuevo enfoque de la práctica médica preventivo-curativa influyó en el desarrollo de la Puericultura, con programas como: Atención integral al niño y la mujer, la normación de las especialidades, la reducción de la mortalidad infantil, la medición de indicadores de salud en la población cubana de 0 a 19 años, la dispensarización de niños y adolescentes, Puericultura prenatal, así como la evaluación de "Hospitales y policlínicos Amigos de la madre y el niño". En 2004 fue creado un grupo multidisciplinario para el rescate de la calidad de las consultas de Puericultura, y se inauguró el Centro de Referencia Nacional de Puericultura en el año 2007, con funciones docentes, de investigación, asistenciales-metodológicas y administrativas. Sorprende la búsqueda de cómo se introdujo en Cuba la Puericultura, a través de Infomed e Internet, visitas a bibliotecas especializadas y la Oficina del Historiador del Ministerio de Salud Pública.

  11. Modeling of Water Quality 'Almendares River'

    International Nuclear Information System (INIS)

    Domínguez Catasús, Judith

    2005-01-01

    The river Almendares, one of the most important water bodies of the Havana City, is very polluted. The analysis of parameters as dissolved oxygen and biochemical oxygen demand is very helpful for the studies aimed to the recovery of the river. There is a growing recognition around the word that the water quality models are very useful tools to plan sanitary strategies for the handling of the contamination. In the present work, the advective, steady- state Streeter and Phelps model was validated to simulate the effect of the multiple-point and distributed sources on the carbonaceous oxygen demand, NH4 and dissolved oxygen. For modeling purposes the section of the river located between the point where the waste water treatment station Maria del Carmen discharges to the river and the Bridge El Bosque, was divided in 11 segments. The use of the 99mTc and the Rodamine WT as tracers allowed determining the hydrodynamic parameters necessary for modeling purposes. The validated model allows to predict the effect of the sanitary strategies on the water quality of the river. The main conclusions are: 1. The model Streeter and Phelps calibrated and validated in the Almendares between the confluence of the channel 'María del Carmen' and bridge the Forest of Havana, described in more than 90% The behavior of the dissolved oxygen and BODn (in terms of ammonia), and more than 85%, the carbonaceous demand oxygen, which characterizes the process of purification. 2. Model validation Streeter and Phelps, indicates that implicit conceptual model is appropriate. This refers primarily to the considerations relating to the calculation of the kinetic constants and the DOS, the segmentation used, to the location of the discharges and the Standing been about them, to the river morphology and hydrodynamic parameters . 3. The calibration procedure Streeter and Phelps model that determines the least-squares Kr-Kd pair that best fits the OD and uses this Kr to model BOD gets four% increase in

    2001-09-01

    Full Text Available De 1959 a 1999, con los datos estadísticos disponibles, la mortalidad infantil en Cuba disminuyó en 81,3 %, la mortalidad neonatal precoz se redujo el 73,4 %, la mortalidad neonatal tardía el 83,6 % y la posneonatal en 86,0 %. Las reducciones obtenidas en el período se distribuyeron uniformemente entre todas las provincias, aunque la mayor disminución se produjo en las provincias centrales y occidentales. Los rubros que más disminuyeron sus tasas fueron: enteritis y otras enfermedades diarreicas, infecciones respiratorias agudas, afecciones perinatales en general y las meningitis, aunque todas las causas reducen la mortalidad en el período. La natalidad descendió el 51,3 %, la fecundidad lo hizo en 30 %, el crecimiento demográfico bruto de la población disminuyó el 59,8 %, el parto institucional aumentó en 65,9 %, el bajo peso al nacer descendió el 36,9 %, la mortalidad perinatal se redujo el 67,2 %, los nacidos vivos disminuyeron el 21,1 % y la supervivencia infantil a los 5 años aumentó el 3,8 %. Esto ha sido posible debido principalmente a la decisión política de priorizar el sector de la salud y muy especialmente la salud maternoinfantil adoptada por nuestro Estado a principios de la década de los 60, lo que permitió alcanzar avances en la organización, calidad de la atención y una amplia cobertura de los servicios de salud. También fueron elementos importantes, el mejoramiento del nivel de vida y de la educación alcanzados por la población, las mejoras logradas en la situación sanitaria y epidemiológica, la distribución equitativa de los alimentos que prioriza a la madre y al niño. Un elemento fundamental en la última década ha sido el desarrollo del "médico de la familia" en la atención primaria y el mejoramiento de la atención hospitalaria. Por otra parte han contribuido de manera notable el establecimiento del Programa Nacional de Atención Maternoinfantil, que abarca las inmunizaciones, el control de las

    Full Text Available En 2011 Cuba aprobó una nueva política económica con el objetivo de relanzar su economía sin comprometer los principales logros sociales asociados a su modelo socialista. La apuesta es lo suficientemente ambiciosa como para generar dudas sobre la posibilidad real de instrumentar con éxito una transformación socioeconómica de tales dimensiones. Lo cierto es que, a pesar de los temores y resistencias a la “actualización” del modelo económico cubano, los cambios internos son obligatorios con el fin de construir un socialismo “próspero y sostenible”, idea que el presidente Raúl Castro ha promovido como objetivo central de los cambios. El artículo analiza las relaciones de Cuba y los países del CARICOM en el contexto de la cambiante realidad cubana actual y examina las posibles modificaciones que esta relación podría experimentar en un futuro próximo como consecuencia de la actualización económica cubana.

Palabras Clave: Cuba, ciencia criolla, autonomismo, intelectuales, nacionalidad. ABSTRACT: This article analyzes the interactions between the Cuban Autonomists, their intellectual positions and their ideas about "nationality", and the use of the concept of "race" made by the Criollo scientists. The first part studies debates on the "ideal" settlers for the forming of a modern and "civilized" nation, which would remove the spectre of "Africanization" from Cuba. The second part of this work is focused on the analysis of the most important cultural review of the time, the Revista de Cuba (1877-1884. It was in this publi- cation —which acted as the voice of Criollo science— that the concept of nationality and the political project of the Autonomists, which was shared by most of the Cuban scientists, was expressed.

Cuando se habla de Socialismo del Siglo XXI no se trata sobre algo definitivamente acabado, conceptualizado, sino precisamente sobre un constructo en desarrollo, el cual es la expresión actual de un abordaje renovado de la construcción del socialismo. Cuba, que inició su proceso revolucionario a mediados del siglo pasado, constituye, con su proyecto de actualización del socialismo, un ejemplo paradigmático donde, con sus características y particularidades históricas, encontramos lo que podríamos llamar una transición del socialismo clásico alternativo sui generis del siglo XX al  socialismo del siglo XXI, con la adopción de políticas públicas que estimulen la sostenibilidad del desarrollo económico y social del país mediante la consolidación de un socialismo próspero y sostenible, comprometido con los valores fundacionales  históricos del proyecto social cubano.

  17. [Eugenic abortion could explain the lower infant mortality in Cuba compared to that in Chile].

    2012-08-01

    Cuba and Chile have the lower infant mortality rates of Latin America. Infant mortality rate in Cuba is similar to that of developed countries. Chilean infant mortality rate is slightly higher than that of Cuba. To investigate if the lower infant mortality rate in Cuba, compared to Chile, could be explained by eugenic abortion, considering that abortion is legal in Cuba but not in Chile. We compared total and congenital abnormalities related infant mortality in Cuba and Chile during 2008, based on vital statistics of both countries. In 2008, infant mortality rates in Chile were significantly higher than those of Cuba (7.8 vs. 4.7 per 1,000 live born respectively, odds ratio (OR) 1.67; 95% confidence intervals (Cl) 1.52-1.83). Congenital abnormalities accounted for 33.8 and 19.2% of infant deaths in Chile and Cuba, respectively. Discarding infant deaths related to congenital abnormalities, infant mortality rate continued to be higher in Chile than in Cuba (5.19 vs. 3.82 per 1000 live born respectively, OR 1.36; 95%CI 1.221.52). Considering that antenatal diagnosis is widely available in both countries, but abortion is legal in Cuba but not in Chile, we conclude that eugenic abortion may partially explain the lower infant mortality rate observed in Cuba compared to that observed in Chile.

    This study sought to assess the effect of the multidimensional approach developed by the International Nosocomial Infection Control Consortium (INICC) on the reduction of ventilator-associated pneumonia (VAP) rates in patients hospitalized in an adult intensive care unit (AICU) in an INICC member hospital in Havana, Cuba. We conducted a prospective surveillance pre-post study in AICU patients. The study was divided into two periods:baseline and intervention. During the baseline period, we conducted active prospective surveillance of VAP using the Centers for Disease Control and Prevention (CDC) National Health Safety Network (NHSN) definition and INICC methods. During the intervention period, we implemented the INICC multidimensional approach for VAP, in addition to performing active surveillance. This multidimensional approach included the following measures: a bundle of infection control interventions, education, outcome surveillance, process surveillance, feedback of VAP rates and performance feedback of infection control practices. The baseline rates of VAP were compared to the rates obtained after intervention, and we analyzed the impact of our interventions by Poisson regression. During the baseline period, we recorded 114 mechanical ventilator (MV) days, whereas we recorded 2350MV days during the intervention period. The baseline rate of VAP was 52.63 per 1000MV days and 15.32 per 1000MV days during the intervention. At the end of the study period, we achieved a 70% reduction in the rate of VAP (RR, 0.3; 95% CI, 0.12-0.7; P value, 0.003.). The implementation the INICC multidimensional approach for VAP was associated with a significant reduction in the VAP rate in the participating AICU of Cuba.

    Dementia is a great challenge to public health in Cuba due to its impact on society and families. Cuba's National Intervention Strategy for Alzheimer Disease and Dementia Syndromes is designed to address this challenge. The Strategy includes working guidelines for primary and secondary care, education about rights of people with cognitive impairment, professional development, research, and health promotion and dementia prevention. An associated action plan, focused on primary care, includes proposals for creation of memory clinics, day centers and comprehensive rehabilitation services for cognitive stimulation. Short-term measures proposed include increasing early detection; creating a dementia morbidity and mortality registry; promoting professional training; providing support for families; and promoting basic and clinical research on dementia. Medium-term proposals aim to reduce dementia incidence and mortality by controlling risk factors and promoting healthy lifestyles, offering new treatment options and optimizing early detection. A set of indicators has been developed to evaluate strategy implementation. With this strategy, Cuba joins the small number of developing countries that have responded to WHO's call to improve care for patients with dementia and alleviate its impact on society and families. KEYWORDS Dementia, Alzheimer disease, aging, national health programs, social stigma, primary prevention, health promotion, civil rights, Cuba.

  2. Fifty years of Cuba's medical diplomacy: from idealism to pragmatism.

    Science.gov (United States)

    Feinsilver, Julie M

    2010-01-01

    Medical diplomacy, the collaboration between countries to simultaneously produce health benefits and improve relations, has been a cornerstone of Cuban foreign policy since the outset of the revolution fifty years ago. It has helped Cuba garner symbolic capital (goodwill, influence, and prestige) well beyond what would have been possible for a small, developing country, and it has contributed to making Cuba a player on the world stage. In recent years, medical diplomacy has been instrumental in providing considerable material capital (aid, credit, and trade), as the oil-for-doctors deals with Venezuela demonstrates. This has helped keep the revolution afloat in trying economic times. What began as the implementation of the one of the core values of the revolution, namely health as a basic human right for all peoples, has continued as both an idealistic and a pragmatic pursuit. This article examines the factors that enabled Cuba to conduct medical diplomacy over the past fifty years, the rationale behind the conduct of this type of soft power politics, the results of that effort, and the mix of idealism and pragmatism that has characterized the experience. Moreover, it presents a typology of medical diplomacy that Cuba has used over the past fifty years.

  6. Courting the future: cancer and genetics in Cuba.

    Science.gov (United States)

    2014-01-01

    Describing this double issue of MEDICC Review could be an exercise for a first-year philosophy course in logic. It's not about "cancer and genetics" in Cuba. It's about cancer in Cuba and about genetics in Cuba, not about exploring relationships between them. Nevertheless, while the marriage of the two themes was fortuitous, in that the two had long been scheduled for the journal in 2014, there is a certain felicity to their sharing an issue. To date, the outstanding accomplishments of genetics have been most helpful for conditions occurring at the beginning of life and cancer is largely (though not exclusively) a disease related to aging. But the two are intrinsically connected: Although only a few of the more than 100 different diseases grouped under the term cancer are known to be hereditary, every cancer begins with a mutation in one or more genes, whether the mutation is inherited, due to an exposure, or is simply a random error in the millions of cell divisions that are part and parcel of cellular reproduction. Our cover image, a stained-glass window by Cuban artist Rosa María de la Terga at Cuba's National Medical Genetics Center, illustrates the elegance of the DNA molecule, the intricate key to life.

    2013-04-01

    Polio was first detected in Cuba in the late 19th century among residents of the US community on the Isla de Pinos (Isle of Pines, now Isle of Youth), apparently introduced through migration from the USA. The first outbreak was reported in 1906 on the Isle, with the first epidemic reported in the former province of Las Villas in 1909. The epidemics subsequently intensified, by 1934 becoming periodic every four to five years, and accompanied by high morbidity, mortality and crippling sequelae, primarily among children. To review and analyze the history of polio and its control in Cuba, from the disease's first appearance in 1898 until WHO/PAHO certification of elimination in 1994. The historiological method was used; archival documents, medical records, and available polio morbidity and mortality statistics from the Ministry of Public Health's National Statistics Division before 1959 and from 1959 through 2000 were reviewed. Crude morbidity and mortality rates were calculated using population estimates at mid-period. Reports and scientific publications describing polio vaccination campaigns and their results were also reviewed, and key informants were interviewed. After initial introduction of polio in Cuba, five major epidemics occurred between 1932 and 1958: in 1934 (434 cases, 82 deaths); 1942 (494 cases, 58 deaths); 1946 (239 cases, 33 deaths), 1952 (492 cases, 15 deaths) and 1955 (267 cases, 8 deaths). Between 1957 and 1961 the disease's endemicity reached epidemic levels, with the last outbreak occurring in 1961, with 342 cases, 30% of them in children aged >4 years. In 1962, Cuba launched a nationwide polio vaccination campaign, the first of annual campaigns thereafter carried out in the framework of a coherent national program aimed at polio elimination. Using the Sabin oral vaccine and targeting the entire pediatric population in a single time period, five million doses were administered in the first campaign, reaching 87.5% of the target population aged 1

En este contexto, resulta muy acertada la publicación del artículo “Algunas variables clínico-epidemiológicas de la tuberculosis pulmonar. Puerto Padre, 2008-2012”, que salió en el Vol.38 No.6.01 del mes de junio de 2013 de la Revista Electrónica Dr. Zoilo E. Marinello Vidaurreta; tanto por el significado social que reviste la divulgación de este tema, como por el propio resultado de la investigación realizada. La historia de la tuberculosis es un tema apasionante. En pocas enfermedades es posible documentar su estrecha relación con la historia de la propia humanidad como en la que nos ocupa. Existen evidencias paleológicas de tuberculosis vertebral en momias egipcias que datan aproximadamente del año 2400 a.C. La tuberculosis se ha conocido a través de la historia, con los nombres de: tisis, consunción, escrófula, mal de Pott, plaga blanca y mal del rey.1 En el artículo se plantea como conclusión que la tendencia de la tuberculosis en el quinquenio de estudio es estacionaria, pero en los últimos cuatro años tiende al ascenso. En los casos diagnosticados de tuberculosis en este quinquenio más de dos tercios correspondieron al sexo masculino y mayores de 45 años, las ocupaciones que más prevalecieron fueron recluso, desocupado, ama de casa y jubilado. Los factores de riesgo que más se relacionaron fueron el albergamiento prolongado en instituciones cerradas, el alcoholismo, y la edad mayor de 65 años; la forma clínica de mayor incidencia en casi la totalidad de los pacientes fue la pulmonar y, dentro de ella, los casos con baciloscopia positiva. Hubo fallas en el diagnóstico, ya que alrededor de la mitad de los casos se diagnosticaron en la atención secundaria y con un tiempo de demora de más de dos meses de

    Full Text: This work is the first approach to establish a monitoring system for heavy metals in the Almendares Vento Basin. This basin is the most important watershed of Havana City, which main river is the Almendares River, that with 42 km of length goes through 5 municipalities, where live more than 500,000 inhabitants. The river receives a large pollution loads from more than 50 pollution sources of Havana City. Inputs of toxic substances like heavy metals come from the industries located along the river and tributaries, the urban discharges and from important speedways in both shores of the river. In the work, concentrations of Cd, Pb, Zn, Cu, Ni, Co and Cr in sediments, water, gastropod species Tarebia granifera Lamarck, macrophyte Eichhornia Crassipes and fish from the specie Gambusia were evaluated at 14 stations during the dry season of 2003. Concentrations of copper and lead in water samples exceeded applicable guidelines for many of the sites monitored in the river basin. Heavy metals in sediments were analysed using three-stage sequential extraction procedure. In sediments high contents of studied metals were found in the bioavailable fraction. Some stations were highly polluted with all elements. Two main sources of pollution with heavy metals could be identified in the basin due to the higher concentration of most of the studied metals in the analized sampling stations. Pb concentrations were high in almost all the stations. Similar behaviour was found for the metal concentration in Eichhornia Crassipes roots, that appear to have an interesting potential as bio monitor of the pollution with heavy metals. Tarebia granifera Lamarck only could be found in 5 of the 14 stations monitored, and it presence is related with the quality of the river water. The magnitude of contamination was estimated by the comparison between local backgrounds and concentration of metals measured. Only high concentration of Zn were found in the Gambusia tissue, and no

    Full Text Available In agricultural landscapes, the Turkey Vulture Cathartes aura feeds mainly on carcases of domestic animals. In spring 2017, data on 214 flocks of Turkey vultures were collected in a road survey in Cuba (in total 2384 km. Turkey Vultures were found to be common accross Cuba, but flock size varied between habitats, reaching a maximum of 43 in valleys and 31 in agricultural landscapes with domestic animal farms. Vultures were active throughout the day, but the time of day did not significantly affect flock size. This study corroborates previous studies which suggested that carrion resources located in agricultural habitats and river valleys is crucial for the continued survival of this still abundant species. Changes in Cuba’s socio-political system in the near future will likely impact agricultural practices, and this in turn will likely affect Turkey Vultures. Our study may serve as a baseline against which future population changes and flocking behaviour of Turkey Vultures can be compared.

    established in Annex 1A of the International Health Regulations 2005 (IHR-2005. METHODS: A descriptive cross-sectional study was conducted by application of an instrument of evaluation of basic capacities referring to legal and institutional autonomy, the surveillance and research process, and the response to health emergencies in 36 entities involved in international sanitary control at the local, municipal, and provincial levels in the provinces of Havana, Cienfuegos, and Santiago de Cuba. RESULTS: The polyclinics and provincial centers of health and epidemiology in the three provinces had more than 75% of the basic capacities required. Twelve out of 36 units had implemented 50% of the legal and institutional framework. There was variable availability of routine surveillance and research, whereas the entities in Havana had more than 40% of the basic capacities in the area of events response. CONCLUSIONS: The provinces evaluated have integrated the basic capacities that will allow implementation of IHR-2005 within the period established by the World Health Organization. It is necessary to develop and establish effective action plans to consolidate surveillance as an essential activity of national and international security in terms of public health.

    The specific activity of Ra-226 in drinking water of Camaguey city, Cuba, was measured using the emanometric method. The specific activity of Ra-226 in drinking water ranged from 15 {+-} 5 mBq.l{sup -1} to 39 {+-}12 mBq.l{sup -1}. The mean specific activity of Ra-226 was found to be 27 {+-} 8 mBq.l{sup -1}. No seasonal variation was found. Water samples were collected from the two main sources of drinking water: private wells and governmental water supply system, being the mean specific activities of Ra-226: 25 {+-} 7 mBq.l{sup -1} and 31 {+-} 9 mBq.l{sup -1} , respectively. Based upon measured concentrations the age-dependent associated effective doses due to the ingestion of Ra-226, as a consequence of direct consumption of drinking water, have been calculated. For the age interval 1 year to 5 years, the average effective dose was 6,2 {mu}Sv.y{sup -1}, and for adults the average effective dose was 5,2 {mu}Sv.y{sup -1}. (author)

    The Almendares river, one of the most important water bodies of the Havana City, is very polluted. The analysis of parameters as dissolved oxygen, biochemical oxygen demand and ammonium is very helpful for the studies aimed to the recovery of the river. There is a growing recognition around the word that the water quality models are very useful tools to plan sanitary strategies for the management of wastewater contamination to predict the effectiveness of control options to improve water quality to desired levels. In the present work, the advective, steady- state, one-dimensional Streeter and Phelps model, calibrated and validated was used to elaborate environment strategies to improve the water quality of the Almendares river. The use of the 99mTc and the Rodamina WT as tracers allowed determining the hydrodynamic parameters necessary for modelling purposes. (Author)

    1992-01-01

    Since 1960 the Soviet Union has been, for all practical purposes, Cuba's exclusive supplier of energy products. For certain time periods, Soviet sales of oil and oil products to Cuba were made at concessional prices; prior to 1991, they were priced using transferable rubles and were essentially bartered for Cuban goods, especially sugar. Effective January 1, 1991, the Soviet Union shifted to world market prices and convertible currency payments for all traded commodities, including energy products. The shift to market prices and convertible currencies in Cuban-Soviet energy trade has already brought - or is likely to bring - a number of adjustments in four areas: (1) the trade balance; (2) the ability to reexport oil and oil products; (3) energy consumption patterns; (4) and the structure of energy supplies. 33 refs., 8 tabs

    2012-01-01

    Full Text Available China’s deepening engagement with Latin America has been accompanied by concerns about the Chinese government’s regard for international conventions of economic governance. Critics claim that across Latin America and the Caribbean, Chinese aid and trade are characterised by excessive state intervention. This article argues that, for two reasons, the rationale for these misgivings is dissipating. First, since the onset of the global financial crisis, China has gained influence in multilateral institutions, prompting them toward greater acceptance of public spending in developing countries. Second, recent developments in Cuba show that China is actively encouraging the Western hemisphere’s only communist country to liberalise its economy. China sits at the crossroads of these local and global developments, prompting Cuba toward rapprochement with international norms even as it works to reform them.

    In Cuba, the application of the radiation technologies has been growing in the last years, and at present there are several dosimetry systems with different ranges of absorbed dose. Diverse researches were carried out on high dose dosimetry with the following dosimetry systems: Fricke, ceric-cerous sulfate, ethanol-chlorobenzene, cupric sulfate and Perspex (Red 4034 AE and Clear HX). In this paper the development achieved during the last 15 years in the high dose dosimetry for radiation processing in Cuba is presented, as well as, the current state of different dosimetry systems employed for standardization and for process control. The paper also reports the results of dosimetry intercomparison studies that were performed with the Ezeiza Atomic Center of Argentine and the International Dose Assurance Service (IDAS) of IAEA.

    Full Text Available The preliminary findings from an unfinished investigation having a synchronic approach are presented. The objective of this study is to analyze the English loanwords that appear in the press of Santiago de Cuba city at the beginning of the XX century. This analysis will allow to draw significant conclusions concerning the presence of anglicisms in the Spanish spoken in Cuba. The methodology is based on a random revision of “El Cubano Libre” newspaper, at the time it is counted some aspects, namely: how many anglicisms were found, their typology, grammatical category, their frequency of appearance, and the year they were published in the dictionary of the Spanish Royal Academy.  Among the outstanding results is remarkable that few English loanwords were registered in the dictionary of the Spanish Royal Academy, the topics more profitable to search were those of politics and sport, and the sort of anglicisms more frequent belong to the category of patent loanword.

    In the paper we present the results of the calibration of the concentration of F-18 dissolution activity in Cuba. Methods of measurement in a calibrated well ionization chamber, traceable to the UK national standard and gamma spectrometry yielded equivalent results within the limit of the associated uncertainties, respectively. The measurement uncertainties of the F-18 activity of the secondary standard activity activator, CAPINTEC CRCTM 15R, obtained from calibration of the instrument with the calibrated solutions of radionuclide, are also shown for the measurement of samples in the geometries of interest in Nuclear Medicine: glass jars and plastic syringes. The results presented in this paper constitute the necessary metrological support for the use of F-18 radiopharmaceuticals and the new PET and PET / CT technologies in medical practice in Cuba.

El caso de Cuba es complejo, pues se dio en una época de desestructuración progresiva de la esclavitud, jalonada por guerras anticoloniales y una modernización tecnológica ininterrumpida. Se argumenta que aunque las condiciones de trabajo no mejoraron en lo sustancial, sí lo hizo la división sexual del trabajo, los patrones de movilidad, y el acceso a la propiedad informal de la tierra. La modernización de Cuba como productor azucarero introdujo fuerzas de inmenso calado en las luchas sociales del período.

    Two of the earliest examples of successful invasive amphibians are the greenhouse frog (Eleutherodactylus planirostris) and the Cuban treefrog (Osteopilus septentrionalis) in Florida. Although both are generally assumed to be recent introductions, they are widespread on Caribbean islands and also have been proposed as natural colonizers. We obtained nucleotide sequence data for both species and their closest relatives in their native and introduced ranges. Phylogenetic analyses trace the origin of E. planirostris to a small area in western Cuba, while O. septentrionalis is derived from at least two Cuban sources, one probably a remote peninsula in western Cuba. The tropical-to-temperate invasion began with colonization of the Florida Keys followed by human-mediated dispersal within peninsular Florida. The subtropical Keys may have served as an adaptive stepping stone for the successful invasion of the North American continent. PMID:21270024

    Family planning gives individuals and couples control and choice over the number of children they have and the timing of their births. Developments in reproductive health have resulted in major changes in the options for family planning, providing more choice and control over fertility. This article explores reproductive health in the Republic of Cuba and the Republic of Ireland, with a focus on contraceptive use and termination of pregnancy as methods of family planning. The predominant religion in both countries is Catholicism, which promotes the right to life of the unborn child. The two countries have adopted different approaches to the availability of both contraception and termination of pregnancy. Cuba has offered free access to contraception and termination of pregnancy since the 1960s to reduce maternal mortality. In Ireland, contraception was not widely available until 1995 and termination of pregnancy is available only in extremely limited circumstances.

    Poliomyelitis was introduced in Cuba in the late nineteenth century by American residents in Isla de Pinos. The first epidemics occurred in 1906 and 1909 and increased in intensity between 1930 and 1958. The scope of the paper is to reconstruct the history of the disease and its epidemics in Cuba prior to 1961, the first National Polio Vaccination Campaign (1962) and its results, as well as analyze the ongoing annual vaccination campaigns through to certified elimination of the disease (1994). The logical historical method was used and archival documents and statistics from the Ministry of Health on morbidity and mortality through 2000 were reviewed. Gross morbidity and mortality rates were calculated and interviews with key figures were conducted.

    Full Text Available ABSTRACT: Multiple pathogens affect sugarcane, among them Puccinia melanocephala, the causal agent of brown rust. This disease was first reported in Cuba in 1979 when it was responsible for a severe attack on the main sugarcane variety B4362. The aims of the present study were to give an overview of sugarcane brown rust in Cuba and show the current disease situation in the country. A retrospective analysis regard to sugarcane cultivar composition resistant to brown rust in Cuba was carried out. In addition 154 genotypes, including the most used progenitors in the breeding program and commercial varieties were evaluated under natural infection conditions. The identity of P. melanocephala was verified by Polymerase Chain Reaction (PCR and by sequencing the ITS1 region. After the introduction of P. melanocephala into Cuba, the susceptible variety, B4362, was replaced by Ja60-5 which remained resistant until 1998. Since 2002, a varietal policy supported by a governmental resolution establishing that any single cultivar cannot occupy more than 20 % of the production area for each production company, local area and province, has been applied. Out of the genotypes evaluated, 49 showed resistance to the disease and 35 intermediate behavior, while 39 were susceptible and 31, highly susceptible. P. melanocephala was detected by PCR in all symptomatic samples and its identify confirmed by sequencing the ITS1 region. The adopted measurement together with permanent phytosanitary monitoring and commercial release of resistant or intermediate cultivars succeeded in avoiding any new epidemic. Inoculum pressure was reduced, even on susceptible and highly susceptible varieties since, by resolution, they cannot occupy more than 10 % of the planted area.

    Previous studies have shown that the HIV-1 epidemic in Cuba displayed a complex molecular epidemiologic profile with circulation of several subtypes and circulating recombinant forms (CRF); but the evolutionary and population history of those viral variants remains unknown. HIV-1 pol sequences of the most prevalent Cuban lineages (subtypes B, C and G, CRF18_cpx, CRF19_cpx, and CRFs20/23/24_BG) isolated between 1999 and 2011 were analyzed. Maximum-likelihood analyses revealed multiple introductions of subtype B (n≥66), subtype C (n≥10), subtype G (n≥8) and CRF18_cpx (n≥2) viruses in Cuba. The bulk of HIV-1 infections in this country, however, was caused by dissemination of a few founder strains probably introduced from North America/Europe (clades B(CU-I) and B(CU-II)), east Africa (clade C(CU-I)) and central Africa (clades G(CU), CRF18(CU) and CRF19(CU)), or locally generated (clades CRFs20/23/24_BG). Bayesian-coalescent analyses show that the major HIV-1 founder strains were introduced into Cuba during 1985-1995; whereas the CRFs_BG strains emerged in the second half of the 1990s. Most HIV-1 Cuban clades appear to have experienced an initial period of fast exponential spread during the 1990s and early 2000s, followed by a more recent decline in growth rate. The median initial growth rate of HIV-1 Cuban clades ranged from 0.4 year⁻¹ to 1.6 year⁻¹. Thus, the HIV-1 epidemic in Cuba has been a result of the successful introduction of a few viral strains that began to circulate at a rather late time of the AIDS pandemic, but then were rapidly disseminated through local transmission networks.

    Full Text Available Tanto la Unión Europea como América Latina, e incluso Estados Unidos, han iniciado distintos procesos de diálogo con Cuba. ¿Cuáles lecciones relevantes se pueden extraer de la larga historia canadiense de compromiso con la Revolución Cubana? Este artículo documenta la evolución de las relaciones entre Canadá y Cuba desde la década de 1940, centrándose en sus altibajos desde que se lanzó, a mediados de la década de 1990, una política de «compromiso constructivo ». Se argumenta que este acercamiento (en sus diversas formas no ha tenido mayor influencia en la liberalización de la política cubana. Además, la poca influencia que Canadá pudo haber tenido durante el «Periodo Especial» ha disminuido con la recuperación económica y diversificación de las relaciones exteriores de Cuba en la última década. En ese sentido, los autores concluyen que la estrategia más apropiada para Canadá y otros actores es llevar a cabo un acercamiento coordinado y de largo plazo que brinde apoyo a una variedad de procesos endógenos de cambio en Cuba. Una estrategia realista debería incluir diálogo de bajo perfil con el régimen actual, cooperación con un amplio espectro de posibles reformadores dentro y fuera del Estado y apoyo para la realización de cambios sociales más extensos a través del comercio, la inversión extranjera, el turismo así como los intercambios académicos y culturales.

Este vínculo se produce en un momento político de Cuba, entre un primer paso de la sucesión de Fidel Castro a Raúl, sin que se den señales claras de una transición hacia otro tipo de sistema político. Mientras tanto, el gobierno de Estados Unidos ha declarado que su prioridad estriba en el reestablecimiento de la democracia en Cuba, tanto durante el último periodo de la administración de George W. Bush como con Barack Obama ya asentado en la Casa Blanca. Sin embargo, las delicadas circunstancias de Cuba (precariedad económica, desastres naturales, dependencia alimentaria y energética, etc. señalan que la prioridad de los intereses nacionales de Estados Unidos se centran primero en la estabilidad del escenario. Incluso al precio del retraso de la evolución del régimen, un cierto grado de seguridad es necesario para enfrentarse a los riesgos de una emigración incontrolada y las hipotéticas tensiones internas que provoquen confrontaciones.

    2012-12-01

    Full Text Available Stokely Carmichael’s visit to Cuba for three weeks in the summer of 1967 illustrates a convergence in the transnational routes of the African American freedom struggle and the Cuban Revolution. African American activists saw Cuba as a model for resisting US power, eradicating racism, and enacting societal change, while the Cuban government considered African Americans allies against US imperialism and advocates of Cuba’s antiracist stance. Amidst racial violence in the United States and Cuba’s efforts to inspire revolution, Carmichael’s presence at the Organization of Latin American Solidarity conference in Havana—and in particular his interactions with Fidel Castro—caused ripples worldwide. A shared “tricontinental” vision that promoted unity in the Global South against imperialism, capitalism, and racism facilitated Carmichael’s solidarity with Castro. Yet divergent views on the role of race in fighting oppression limited their solidarity. Carmichael and Castro’s spectacular alliance demonstrated their personal affinity and ideological commonalities but did not result in an institutional alliance between the black liberation movement and the Cuban state. Instead Carmichael’s connection with the Cuban Revolution left an underexplored legacy. Examining Carmichael’s visit to Cuba illustrates the possibilities and pitfalls of transnational solidarity and furthers our understanding of postwar struggles for change.

    2017-01-01

    There has been a notable decrease in the global practice of clinical autopsy; the rate has fallen to below 10%, even in high-income countries. This is attributed to several causes, including increased costs, overreliance on modern diagnostic techniques, cultural and religious factors, the emergence of new infectious diseases and negative attitudes on the part of doctors, even pathologists. Alternative methods to autopsy in postmortem studies have been developed based on imaging, endoscopy and biopsy (all quite expensive). These methods have been used in developed countries but never as effectively as the classic autopsy for identifying cause of death and potential medical errors. Although Cuba has also seen a decrease in its autopsy rates, they remain comparatively high. Between 1996 and 2015, there were 687,689 hospital deaths in Cuba and 381,193 autopsies, 55.4% of the total. These autopsies have positively affected medical care, training, research, innovation, management and society as a whole. Autopsies are an important tool in the National Health System's quest for safe, quality patient care based on the lessons learned from studying the deceased.

    prevailing environmental conditions in the study area. For data collection, six sampling sites were located every 2-3km ranging from 12m to 17m depth along the spur-and-groove reefs. In each site, 22-26 1m² quadrants were zigzag arranged every 2m. The density of colonies was determined per site. The severity degree and predictability of environmental conditions were inferred by using the Heterogeneity and Equitability indexes, respectively. Hydrodynamic stress and the Comparative Pollution Index were also assessed. Current affectations of the octocoral communities were also determined and classified into four main categories: mechanical damage, diseases, predation and invertebrate and macroalgae overgrowth. As a result, 25 species represented by 752 colonies were recorded and Eunicea flexuosa and Gorgonia ventalina were the most abundant. The occurrence of Eunicea succinea forma succinea constituted the first report for Eastern Cuba. Site densities ranged from 3.58±1.84 to 7.58±2.16 colonies/m² and considered from moderate to low. The biggest densities were reported at both sides of the San Juan River mouth. Despite of the composition and structure of the octocoral communities, low to high hydrodynamic stress and low and moderate levels of contamination were inferred, it is likely that these indexes could have been overestimated due to the sensitivity of the indicator species to other factors such as sedimentation. The environmental conditions were mostly favorable and stable. In general, the number of dead colonies was low and mostly caused by the detachment of the substrate and overgrowth of Millepora alcicornis. Injuries were mainly brought about by mechanical damage, followed by coenenchyme loss, predation by Cyphoma gibbosum and macroalgae overgrowth. On the other hand, negative effects by Hermodice carunculata predation, bleaching, Red Band and Black Band Disease were not observed. Among sampled species, G. ventalina colonies were the most severely damaged within

    Full Text Available O objeto deste artigo é o conceito de verdade tal como se articula no oráculo de Ifá cubano; seu objetivo é ilustrar a fecundidade de um "método ontográfico" que procure mapear as premissas ontológicas do discurso nativo por meio da produção de conceitos que, não sendo os conceitos nativos eles mesmos, constituam equivalentes aproximados destes. Enfatizando a afirmação dos praticantes de que o Ifá é infalível, propõe-se que os vereditos divinatórios devem ser entendidos como verdades necessárias, isto é, como enunciados que não poderiam não ser verdadeiros. Em seguida, mostrando que, do ponto de vista das concepções comuns de verdade, a necessidade modal dos oráculos só pode parecer um absurdo dogmático, procura-se avançar uma conceitualização alternativa que concorde com as convicções dos informantes, examinando um complexo de conceitos e práticas associados ao oráculo a fim de avaliar as premissas que garantem a verdade e sua emergência na prática do Ifá.This article analyzes the concept of truth as employed by Ifá oracles in Cuba; its aim is to illustrate the fertility of an 'ontographic method' dedicated to mapping the ontological premises of native discourse through the production of concepts which, while not the native concepts themselves, comprise close equivalents to them. Emphasizing practitioners claims that the Ifá is infallible, it is proposed that divinatory verdicts should be understood as necessary truths, that is, as statements which cannot not be true. Then, after showing that from the viewpoint of common place conceptions of truth, the modal necessity of oracles can only appear a dogmatic absurdity, I propose an alternative conceptualization which agrees with the convictions of informants. This involves examining a complex of concepts and practices linked to the oracle in order to evaluate the premises which ensure truth and its emergence in Ifá practice.

    The intertwined history of Cuba and Guatemala goes back almost five centuries. In 1536, Friar Bartolom� de las Casas sailed from Cuba to Guatemala with material for his book, A Brief Account of the Destruction of the Indies, seared upon his conscience. Documenting atrocities against Cuba's indigenous populations, the book persuaded Guatemala's colonial powers to rewrite abusive labor laws that were killing the Maya; the book also earned De las Casas the nickname 'apostle of the Indians.' Over 300 years later, the apostle of Cuban independence, Jos� Mart�, cut his journalistic teeth in Guatemala, while Cuban poet Jos� Joaqu�n Palma authored Guatemala's national anthem. More recently, in the 1950s, Dr Ernesto ('Che') Guevara's time in the country solidified his belief in the need for radical social change a few years before he would join Fidel Castro's Rebel Army. And in 1998, Guatemala, like Cuba so many times before and since, was struck by a fierce, fatal hurricane, opening in its wake a new chapter in the countries' shared history. Hurricane Mitch took over 30,000 lives in Central America and is widely considered the deadliest hurricane to hit the Western Hemisphere in 200 years. The storm made landfall in Guatemala on October 26, 1998 killing 268 people and displacing 106,000. Losses were estimated at US$750 million, with 6,000 homes completely destroyed and another 20,000 damaged. Seven health centers and 48 rural health stations serving 50,000 people were affected.[1] Within days, a team of 19 Cuban doctors landed in Puerto San Jos� in the southern department of Escuintla to provide medical assistance. Working alongside Spanish, US, and Guatemalan relief workers, the Cuban contingent set broken bones, treated some 900 cases of cholera[2] and 14,000 of malaria,[3] evacuated pregnant women, and delivered babies. Implementing vector control, safeguarding food supplies, and providing potable water were other measures taken by the Cuban volunteers, who

    2012-04-01

    Gender identity is a sociocultural construct based (in nearly every society) on a binary norm: female and male. Transsexual individuals suffer from intense family and social discrimination because they express a dissident sexuality incongruent with this norm. They assert they feel trapped in a body that does not belong to them, so they seek help from health professionals to modify their bodies, to "adapt their bodies to their minds." This essay discusses health care for transsexual persons in Cuba from a human rights perspective that does not pathologize their gender identification.

    For more than 15 years we have tried to use in Cuba ionizing radiations for the genetic improvement of plants without any encouraging results. This is so mainly because the dose values to be used were taken from reports which appeared in specialized literature most of it from countries in cold or temperature zones. Two Cuban researchers proved that cuban varieties are more resistant to radiations than the ones reported in literature, thus the need to make a radiosensitivity table which would allow improvers to use successfully the radio mutational method in cuban agriculture

    An isotopic dispersive model is applied to the Jaruco and Aguacate karstic groundwater basins of Western Cuba. The best fit of the model was validated with stable ( 18 O and 2 H ) and radioactive ( 3 H) isotopes. Modeling showed an aquifer stratification in two basic levels with turnover times of three month to upper level and close to 100 years to the lower level. The last one mainly supplies the base flow of the Ojo de agua and Bello springs and therefore, controls the dry season exploitation yields of the aqueducts of El Gato and Bello. Model results introduces an important constraint in the exploitation of groundwater resource of both aquifer systems

    INTRODUCTION Suicide is a health problem influenced by biological, genetic, psychological, social and economic factors. It is responsible for 50% of violent deaths in the male population, worldwide, and 71% in the female. In the Americas, 65,000 deaths by suicide occur every year. It is the ninth most frequent cause of death in Cuba, and third among people aged 10-19. OBJECTIVE Characterize the epidemiology of suicide in Cuba from 1987 to 2014. METHODS A retrospective descriptive study was conducted. The information comprised all records of death by suicide from January 1, 1987 to December 31, 2014, in the Cuban Ministry of Public Health's National Statistics Division database. The variables were sex, age, skin color, employment status/occupation, marital status, and method of suicide. Crude and age-standardized mortality rates and age-sex specific mortality rates were calculated, all per 100,000 population, as well as the sex ratio. Relative change over the series was calculated as a percentage. Distribution of suicides by variable was calculated and proportions expressed as percentages. RESULTS A total of 51,113 deaths by suicide were reported (annual average 1825), of which 34,671 (67.8%) were among men. The sex ratio was 2.1:1 for the entire study period, and 3.9:1 for 2011-2014. Over the course of the period studied, age-standardized suicide rates decreased from 23.9 to 10.8 per 100,000 population (54.8% reduction). The group aged ≥60 years had the highest average age-standardized rate, 44.6 per 100,000 population. The highest suicide burden by age was in the group aged 20-59 years (60.5%). By skin color, the highest burden was in those recorded as white, 68.9%. By marital status, the highest burden was in persons with a stable partner (46.7%), and by employment status/occupation, in retired (25.9%). The most commonly used method was hanging (59.4%). CONCLUSIONS Over the course of about three decades, suicide mortality rates have declined by almost half and

Planificar las cantidades de medicamentos necesarias, para lograr garantizar una disponibilidad adecuada de estos en todos los niveles de asistencia, es una tarea en la cual intervienen un sinnúmero de factores. El objetivo de este trabajo fue demostrar en qué medida la introducción del enalapril tabletas influyó en el consumo del captopril tabletas, mediante el análisis de los patrones de consumo de los medicamentos inhibidores de la enzima convertidora de angiotensina en el territorio oeste de La Habana entre marzo de 2005 y diciembre de 2009. Para ello se realizó un estudio de utilización de medicamentos de consumo, de tipo descriptivo, observacional y retrospectivo. Se calcularon las DHD (dosis por mil habitantes día. Los resultados de este trabajo demuestran cómo en este grupo hay un desplazamiento del consumo hacia el enalapril. Este es un comportamiento lógico por la comodidad de la administración y la menor incidencia de efectos adversos. Sin embargo, el captopril se mantiene en valores entre 20 y 30 DHD x 1 000 habitantes ya que hay un grupo de pacientes que continúan con este tratamiento y es de elección en la crisis hipertensiva.The planning of resources is a pressing problem in the developing nations including Cuba, hence using restricted budgets and dwindling foreign currencies in the best possible way is a must.

    The Almendares river, one of the most important water bodies of the Havana City, is very polluted. The analysis of parameters as dissolved oxygen and biochemical oxygen demand is very helpful for the studies aimed to the recovery of the river. There is a growing recognition around the word that the water quality models are very useful tools to plan sanitary strategies for the management of wastewater contamination to predict the effectiveness of control options to improve water quality to desired levels. In the present work, the advective, steady- state Streeter and Phelps model was calibrated and validated to simulate the effect of multiple-point and distributed sources on the carbonaceous oxygen demand and dissolved oxygen. The use of the 99mTc and the Rodamine WT as tracers allowed determining the hydrodynamic parameters necessary for modeling purposes

From 14 species of macroalgae (Phaeophyta, Chlorophyta, and Rhodophyta, 1340 samples were obtained identifying seven species as potentially noxious; five of them are new reports for Cuba’s phytobenthos: Prorocentrum belizeanum Faust, P. concavum Fukuyo, P. mexicanum Tafall, Coolia monotis Meunier, and Ostreopsis lenticularis Fukuyo. ANOVA/MANOVA analysis showed significant spatial differences: lower cell abundance near the shoreline adjacent to a river inlet and higher cell abundance in the deepest area. Prorocentrum lima (Ehrenberg Dodge 1975 was found mainly on Phaeophyta followed by Chlorophyta and Rhodophyta. Gambierdiscus toxicus was found mainly on Phaeophyta followed by Rhodophyta and Chlorophyta. All the species reported in the study area were mainly on Padina spp. (Phaeophyta. Acanthophora spicifera (Rhodophyta did not host dinoflagellate species. Environmental conditions in summer (higher temperature, more nutrients, greater water transparency, and low wind intensity are suitable for macroalgae development, which serves as a substrate for potentially harmful dinoflagellates, and possibly the main vector for spreading ciguatera along the coast of Cuba.

    Cuba's Energy Revolution is a national program for developing renewable energy sources to conserve energy, promote sustainable development and address environmental concerns. It includes the Energy Saving Program by the Ministry of Education (PAEME), the Electricity Saving Program in Cuba (PAEC) by the Ministry of Basic Industry (MINBAS) and the National Program for Energy Sustainable Culture developed by CUBASOLAR. The most important programs related to the use of renewable energy sources have been carried out in the field of biomass, hydropower, wind energy, water supply and solar photovoltaic energy in rural areas. This paper presented the Cuban experiences on education, diffusion and publication of energy themes. Mass communication including television, radio and magazines has been used to explain the rationale of using renewable energy, its efficiency and social impact. The positive results thus far indicate that these measures can be applied in other developing countries such as Latin America and Caribbean, and could also serve as a guide for other areas, including developed countries.

    Full Text Available 1898 es para España el año del Desastre, con mayúscula; 1898 es para Cuba el año de la independencia, quizá con minúscula. Canarias es la puerta de salida de Europa; Cuba es puerta la entrada de América. La migración canario - cubana ha sido un factor histórico decisivo en la formación de ambas nacionalidades. La prensa de masas naciente a fines del siglo XIX jugó un papel determinante en la guerra hispano-norteamericana y su desenlace. Conjugando esas cuatro sentencias aplastantes y archiconocidas, la investigación del reflejo del proceso independentista cubano en la prensa de canaria aporta sustanciosos elementos al conocimiento del papel de los procesos de comunicación en la historia y en la cultura de ambos archipiélagos, en el importante contexto del fin de siglo XIX.

    The fourth Tuberculosis (TB) Symposium, held during the Cuba Salud 2015 International Convention, highlighted advancements in research on TB and Mycobacterium tuberculosis (Mtb) by interdisciplinary teams from academic and federal institutions in Cuba, Colombia, Mexico, and the Dominican Republic. Delegates focused on the targets presented in the World Health Organization End TB Strategy for 2016-2035 and elaborated on four primary themes: 1) attention to vulnerable populations such as immunocompromised individuals, health care workers, and residents of long-term institutions such as prisons and nursing homes; 2) identification of active and latent TB cases through contact investigations; 3) spread and control of drug-resistant Mtb strains; and 4) advancements in the development of novel vaccines or "booster" immunizations. This international TB forum served as a platform for experts in diverse disciplines in these Latin American countries to discuss challenges faced by TB research and control programs, proposing novel research initiatives and promoting collaborative teamwork strategies for TB elimination. In solidarity, collaborative efforts in TB control require identification of symptomatic individuals, rapid diagnostic testing for TB, drug susceptibility assays on Mtb strains, and management that provide universal and gratuitous access to directly observed short-course therapy.

    Island organisms often have wider feeding niches than mainland organisms, and migratory birds breeding on continents often widen their niches when overwintering on islands. Cuba's low hummingbird richness has puzzled ornithologists for decades. Here, we show that the Cuban hummingbird fauna is less...... rich than expected based on Cuba's elevation, when compared to the rest of the West Indian islands. Thereafter, we report nectar-feeding behaviour by 26 non-Trochilidae bird species in Cuba, encompassing pigeons/doves, woodpeckers and passerines, and endemic, resident and migratory species.

    This paper presents the results of the analysis of Ca, Fe, Zn, Br, Rb, Sr and Pb in samples of lichens used as biomonitors of air pollution collecting in Havana City during 2009-2010. Two different X-Ray Fluorescence methods were used. First, a combination of Si (Li) detector with an annular 109Cd as primary excitation source was employed. The second system consisted in a Mo X-ray tube with a secondary target of Molybdenum and a X-PIPS detector. In both configurations, the correction of matrix effects was achieved by using the Compton scattering peak. The quantification was performed using calibration curves obtained from different biological Certified Reference Materials. The determination of elements by Inductively Coupled Plasma-Atomic Emission Spectrometry, Inductively Coupled Plasma-Mass Spectrometry and Flame Atomic Absorption Spectrophotometry was carried out in order to evaluate the reliability of XRF methods. No significant differences were found between the obtained results by the different techniques. The levels of concentration of the analyzed elements in the lichens in 2009 and 2010 respectively were similar. The elemental distribution patters obtained for each metal were associated with different sources of contamination. (Author)

    Acute gastrointestinal illness is an important public-health issue worldwide. Burden-of-illness studies have not previously been conducted in Cuba. The objective of the study was to determine the magnitude, distribution, and burden of self-reported acute gastrointestinal illness in Cuba. A retrospective, cross-sectional survey was conducted in three sentinel sites during June-July 2005 (rainy season) and during November 2005–January 2006 (dry season). Households were randomly selected from a list maintained by the medical offices in each site. One individual per household was selected to complete a questionnaire in a face-to-face interview. The case definition was three or more bouts of loose stools in a 24-hour period within the last 30 days. In total, 97.3% of 6,576 interviews were completed. The overall prevalence of acute gastrointestinal illness was 10.6%. The risk of acute gastrointestinal illness was higher during the rainy season (odds ratio [OR]=3.85, 95% confidence interval [CI] 3.18-4.66) in children (OR=3.12, 95% CI 2.24-4.36) and teens (OR=2.27, 95% CI 1.51-3.41) compared to people aged 25-54 years, in males (OR=1.24, 95% CI 1.04-1.47), and in the municipality of Santiago de Cuba (OR=1.33, 95% CI 1.11-1.61). Of 680 cases, 17.1-38.1% visited a physician, depending on sentinel site. Of the cases who visited a physician, 33.3-53.9% were requested to submit a stool sample, and of those, 72.7-100.0% complied. Of the cases who sought medical care, 16.7- 61.5% and 0-31.6% were treated with antidiarrhoeals and antibiotics respectively. Acute gastrointestinal illness represented a substantial burden of health compared to developed countries. Targeting the identified risk factors when allocating resources for education, food safety, and infrastructure might lower the morbidity associated with acute gastrointestinal illness. PMID:19507750

    In Cuba, alcohol is an important contributor to morbidity, mortality and social problems. The foundation of Cuba's universal primary health care coverage, family doctor-and-nurse offices play a critical role in prevention, early detection and treatment of alcohol abuse. Los Palacios Municipality of the westernmost province of Pinar del Río, Cuba, is a socially complex, periurban area where alcohol abuse and alcoholism have been identified as important health problems. Adolescents constitute a population at high risk for alcohol abuse because of their receptivity to social influences, but the precise extent of the problem is unknown. This paper reports baseline findings from a survey and direct observation of alcohol consumption in the catchment area of a primary care center, conducted to inform planning for an educational intervention.

    In 2015, a record-breaking 3.5 million visitors-1 million from Canada alone-traveled to Cuba to explore its history, culture, natural splendor, and visit family. That same year, US President Barack Obama relaxed travel restrictions, giving general authorization for a dozen categories of legal travel by US citizens and residents. As a result, US visitors to the island ballooned by 80% between January 2015 and June 2016. And the numbers keep growing: the latest data show that foreign arrivals reached 4 million in 2016.[1] The surge in visitors highlights the potential negative impact of tourism on a developing country's infrastructure, environment, cultural patrimony and local economy-all considered important social determinants of health.

    Full Text Available M. hyorhinis is considered one of the etiological agents of arthritis in sucking pigs, but recently as seen, some strains can produce pneumonia that could not be distinguished from the mycoplasmosis caused by M. hyopneumoniae. The study was conducted to research the presence of Mycoplasma hyorhinis (M. hyorhinis in different regions of the country from exudates of pig lungs with typical EP lesions. Exudates from 280 pig lungs with typical EP lesions were studied using molecular techniques such as PCR, real time PCR and amplification of the 16S-23S rRNA. It was detected that the 66% of the samples studied resulted positive to M. hyorhinis, and the presence of this species was detected in all the provinces. Amplification and studies on the intergenic region 16S-23S of M. hyorhinis rRNA demonstrated the existing variability among strains of a same species. This study is the first report on M. hyorhinis detection in Cuba.

    Rivulus berovidesi, a new killifish species, is described from a small stream in Sierra de Cajalbana, northwestern Cuba. It is readily distinguished from Rivulus cylindraceus Poey by the combination of an exclusive color pattern and meristic characters such as a d-type frontal scalation pattern (versus e-type pattern in Rivulus cylindraceus). The current diagnosis of Rivulus berovidesi based on chromatic, morphological and meristic characters is consistent with a recent molecular analysis of this genus in Cuba.

A partir de los resultados de estas transformaciones se delimitaron zonas donde predominan las rocas ultrabasicas serpentinizadas tanto en superficie como en profundidad, definiendose la extension lateral de estas rocas por debajo de las rocas que afloran en superficie. Tambien se estimaron las variaciones de los espesores de las rocas ofioliticas, el basamento de las rocas que afloran, la presencia de estructuras disyuntivas, y se proponen nuevas estructuras de este tipo. Por ultimo se delimitan las zonas de alteracion hidrotermal, lo cual posee gran importancia, ya que con las mismas se pueden vincular mineralizaciones de metales preciosos. Ademas, su delimitacion en depositos lateriticos permite orientar los trabajos de explotacion minera, teniendo en cuenta el dano que causa al proceso metalurgico la presencia de material silicio en las lateritas Fe+Ni.

    Full Text Available Cuba está ubicada en una zona de países con alta incidencia de dengue. En los últimos 10 años ha sido afectada por varias epidemias, es por ello que se diseñó, implementó y evaluó una estrategia participativa, basada en el enfoque de ecosalud, la cual estuvo dirigida a propiciar acciones intersectoriales en la gestión del ecosistema para disminuir las poblaciones del mosquito Aedes aegypti y prevenir la transmisión de dengue en el municipio Cotorro de Ciudad de La Habana, Cuba. Para el desarrollo de este trabajo se utilizó la metodología de investigación acción participativa. Como resultado del proceso se pudo describir una estrategia que garantiza la participación activa de la comunidad, los sectores y el gobierno en la producción de ecosistemas saludables, se desarrollaron acciones de prevención y control oportunas e integrados que disminuyeron los riesgos para la proliferación del vector y la transmisión local de la enfermedad. Este enfoque permitió el análisis holístico de los problemas, su priorización y la gestión de sus soluciones; la estrategia se sostiene dos años después de concluido el proceso.Cuba is located among a group of countries with high dengue incidence.

    An isotopic dispersive model is applied to the Jaruco and Aguacate karstic groundwater basins of Western Cuba. The best fit of the model was validated with stable ({sup 18}O and 2{sup H}) and radioactive ({sup 3}H) isotopes. Modeling showed an aquifer stratification in two basic levels with turnover times of three month to upper level and close to 100 years to the lower level. The last one mainly supplies the base flow of the Ojo de agua and Bello springs and therefore, controls the dry season exploitation yields of the aqueducts of El Gato and Bello. Model results introduces an important constraint in the exploitation of groundwater resource of both aquifer systems.

Los resultados de esta experiencia demostraron la aplicabilidad y factibilidad del Manual de Acreditación y de la Guía de Indicadores de Calidad de los Servicios Farmacéuticos Hospitalarios elaborados en el presente estudio, ya que su instrumentación se realizó con la información y los controles habituales que están regulados por la Dirección Nacional de Farmacia, como órgano rector de esta actividad en el país.The mission of the hospital pharmacies is to assure the optimal drug therapy to the patient. To fulfil this purpose, it is required to implement a quality assurance program for the permanent improvement and to have the Accreditation Manual and the quality requirements in place to apply this type of programs. The objective of this paper was to lay down the strategy to be followed for the implementation of an Accreditation Program directed to Hospital Pharmacy Services in Cuba, through the preparation and evaluation of an Accreditation Manual and a Quality Indicator Guide adapted to the national setting. They were both prepared after consulting the corresponding programs of international institutions and from Argentina, Spain and Brazil. The design of the manual and the program in effect in Cuba for the hospital accreditation were taken into account in addition to selecting process-based quality indicators as fundamental tools in the quality assessment. Panels of experts evaluated the two research works with the Delphy method. The applicability and feasibility of these results in a secondary care hospital of Havana were corroborated. Twenty five Cuban experts reviewed and evaluated the Accreditation Manual, who also selected the best suitable indicators adjusted to the functions of the Cuban hospital pharmacies. For the preparation of the quality indicators, it was necessary to carry out a process of changes covering the particularities of the service to which they are intended

    The river Almendares, one of the most important water bodies of the Havana City, is very polluted. The analysis of parameters as dissolved oxygen and biochemical oxygen demand is very helpful for the studies aimed to the recovery of the river. There is a growing recognition around the word that the water quality models are very useful tools to plan sanitary strategies for the handling of the contamination. In the present work, the advective, steady- state Streeter and Phelps model was validated to simulate the effect of the multiple-point and distributed sources on the carbonaceous oxygen demand, NH4 and dissolved oxygen. For modeling purposes the section of the river located between the point where the waste water treatment station Maria del Carmen discharges to the river and the Bridge El Bosque, was divided in 11 segments. The use of the 99mTc and the Rodamine WT as tracers allowed determining the hydrodynamic parameters necessary for modeling purposes. The validated model allows to predict the effect of the sanitary strategies on the water quality of the river

  3. Increased sex ratio in Russia and Cuba after Chernobyl: a radiological hypothesis

    Science.gov (United States)

    2013-01-01

    Background The ratio of male to female offspring at birth may be a simple and non-invasive way to monitor the reproductive health of a population. Except in societies where selective abortion skews the sex ratio, approximately 105 boys are born for every 100 girls. Generally, the human sex ratio at birth is remarkably constant in large populations. After the Chernobyl nuclear power plant accident in April 1986, a long lasting significant elevation in the sex ratio has been found in Russia, i.e. more boys or fewer girls compared to expectation were born. Recently, also for Cuba an escalated sex ratio from 1987 onward has been documented and discussed in the scientific literature. Presentation of the hypothesis By the end of the eighties of the last century in Cuba as much as about 60% of the food imports were provided by the former Soviet Union. Due to its difficult economic situation, Cuba had neither the necessary insight nor the political strength to circumvent the detrimental genetic effects of imported radioactively contaminated foodstuffs after Chernobyl. We propose that the long term stable sex ratio increase in Cuba is essentially due to ionizing radiation. Testing of the hypothesis A synoptic trend analysis of Russian and Cuban annual sex ratios discloses upward jumps in 1987. The estimated jump height from 1986 to 1987 in Russia measures 0.51% with a 95% confidence interval (0.28, 0.75), p value < 0.0001. In Cuba the estimated jump height measures 2.99% (2.39, 3.60), p value < 0.0001. The hypothesis may be tested by reconstruction of imports from the world markets to Cuba and by radiological analyses of remains in Cuba for Cs-137 and Sr-90. Implications of the hypothesis If the evidence for the hypothesis is strengthened, there is potential to learn about genetic radiation risks and to prevent similar effects in present and future exposure situations.

    Full Text Available Administrative corruption in Cuba during the nineteenth century was a serious problem addressed both by Spanish authorities and the critics of the colonial system in Cuba. In the long run the fiscal, financial, institutional, and ideological costs of corruption undermined Spanish colonial control in Cuba. While the state and Cuban taxpayers had to pay for the increased costs of corruption, corrupt public officials and private contractors and financiers benefited. This study uses both archival manuscript administrative sources and published sources to assess the impact of corruption and its institutional bases during the final phase of Spanish colonialism in Cuba and the early period of post-colonial transition.

    La corrupción administrativa en Cuba durante el siglo XIX constituyó un problema reconocido como muy grave tanto por las autoridades españolas como por los críticos del sistema colonial cubano. Los costos fiscales, institucionales, e ideológicos de la corrupción contribuían a la erosión del dominio español en Cuba. A causa de la corrupción el Estado percibía menos ingresos y los contribuyentes cubanos se veían forzados a llevar a cuestas una creciente deuda pública. Los funcionarios corruptos y los contratistas y financistas privilegiados por el rígido sistema colonial, por el contrario, percibían los beneficios informales a que se creían acreedores por defender el dominio territorial español en Cuba. Utilizando fuentes administrativas manuscritas de archivos cubanos y españoles, así como fuentes públicas impresas, este trabajo evalúa el impacto de la corrupción y sus particulares bases institucionales en la fase final del colonialismo español en la isla y la transición post-colonial temprana.

    In 1961, the USA severed diplomatic relations with Cuba, and in 1962 an embargo was imposed on trade and financial relations with that country. It was not until five decades later that the USA and Cuba would reestablish relations. This opened the way for the New York State Trade Mission to Cuba in April 2015, during which Cuba's Molecular Immunology Center and Buffalo, New York's Roswell Park Cancer Institute signed a formal agreement that would set in motion biotechnology research collaboration to address one of the most important causes of death in both countries. Significant research from Cuba led to this groundbreaking collaboration. The purpose of this paper is to discuss the development of this cooperation, from the Molecular Immunology Center's initial investigations, through the opening of a phase I clinical trial at Roswell Park Cancer Institute with therapies developed at the Center. This cooperation was responsible for the first clinical trial for CIMAvax-EGF involving advanced-stage non-small cell lung cancer patients in the USA. A license was also approved by the US Department of the Treasury's Office of Foreign Assets Control authorizing a commercial partnership for development of biotechnology products, combining the cancer research efforts of both institutions. This unusual collaboration between Cuba and the USA-the US economic embargo and travel restrictions not withstanding-opens good prospects for expanded medical research between the two countries. While political and logistical challenges remain, the shared mission and dedication of these Cuban and US scientists points the way towards relationships that can lead to development, testing, approval and use of promising new therapies for cancer patients.

    Full Text Available Drawing on research in Cuba and the Dominican Republic this paper explores the uses of intimacy in both the corporate sector and in romantic relationships. I use research with hotel workers and with people involved in sexual-affective exchanges connected to tourism to link intimacy to the political economic structures of transnational tourism. These are new spaces of analysis that present practices of transnational corporategenerated intimacy that combine love – or the exploitation of worker’s emotions − and labour. The central aim is to intertwine the intimate with the global, from the formal customer service policies of transnational hotels with the informal, on-the-ground, intimate encounters between tourists and hospitality workers. The commercialization of intimacy, including sexual-affective relations in the delivery of hospitality services, is linked to political and economic processes that are part of transnational tourism practices. This paper challenges the notion that sex tourism and sex work are individualistic practices that exist outside of the spaces of corporate global profit. It further posits that relationships where money is exchanged are not necessarily devoid of care and intimacy.Resumen: Encuentros íntimos: economías afectivas en Cuba y República Dominicana A partir de investigaciones en Cuba y la República Dominicana, este trabajo explora los usos de la intimidad, tanto en el sector empresarial como en las relaciones románticas.

    validate the efficacy of this method. Methods: a sample of 227 children treated at the Center of Urinary Lithiasis Treatment in "Hermanos Ameijeiras" hospital of Havana, Cuba, from April 1986 to October 2011. Three types of lithotripters were used: HM3 (Dornier, Lithostar Plus (Siemens y Medical Modulith® SLX (Storz. Results: the ages ranged from 2 to 18 years. The numbers of treated females and males were similar (51 % and 49 %. The prevailing symptom was nephritic colic with renal calculi (81.9 % and in the urether (18.1 %. The mean affected surface was 1.20 cm². General orotracheal(34.4 % and general intravenous (65.6 % types of anesthesia were used. Eight cases (3.52 % required repeated treatment. The complications were acute urinary infection (3.08 % and renal subcapsular hematoma (0.88 %. Lithiasis was eliminated in 96.04 % of patients. Conclusions: this therapy based on extracorporeal shock wave lithotripsy proved to be effective, with low mortality and serious complication rates, so it should be scientifically defended as the first therapeutic option in the elimination of urolithiasis at these ages. It must be remembered that the elimination of calculi is not enough since the disease must be identified, treated in depth, and relapses must be avoided.

    The aim of this analysis was to obtain information regarding the mtDNA haplotype composition of the manatee (T. manatus) occupying the Cuban archipelago. A fragment of 410 bp of the non-coding region was analyzed for 12 individual manatees from Cuba and one from Florida, USA. Only two haplotypes were identified. Haplotype A1, found exclusively in Florida (including in the sample analyzed here) but also found in Mexico, the Dominican Republic and Puerto Rico, was the most frequent haplotype (11 of the 12 samples from Cuba) and widely distributed. The second haplotype A3, previously referred to as endemic from Belize, was identified from an individual stranded in Isabela de Sagua, north of Cuba. These preliminary results provide information about three major aspects of manatee biology: (1) the mtDNA genetic diversity of T. manatus in Cuba seems low as compared to other regions of the Caribbean; (2) the Cuban population likely belongs to the group comprising Florida and the portions of the Greater Antilles; and (3) the territories of Belize and Cuba have exchanged individuals at present or in a relatively recent past.

    Full Text Available Essential oil of Cymbopogon citratus collected from Brazil and Cuba was tested to a chemical characterization and then was tested on the post-embryonic development of Musca domestica. The chemical composition analysis by GC-MS of the oils from Brazil/Cuba allowed the identification of 13 and 12 major constituents respectively; nine of them common to both. In the both oils, the main components were the isomers geranial and neral, which together form the compound citral. This corresponds to a total of 97.92%/Brazil and 97.69%/Cuba of the compounds identified. The monoterpene myrcene, observed only in the sample of Cuba, presented a large relative abundance (6.52%. The essential oil of C. citratus (Brazil/Cuba was dissolved in DMSO and tested at concentrations of 5, 10, 25, 50, 75 and 100% and citral was prepared by mixing 16.8 mg with 960 µL DMSO. Both essential oils and monoterpene citral were applied topically to newly-hatched larvae (1µL/larva. The results showed a lethal concentration (LC50 of 4.25 and 3.24% for the Brazilian and Cuban essential oils, respectively. Mortalities of larval and newly-hatched larvae to adult periods were dose-dependent for the two both oils as for monoterpene citral, reaching 90%.

    The appropriate handling of the dangerous waste has become a topic of high priority for all the countries and especially for those developing one that in general, they lack solid technical infrastructure, suitable technologies and human resources properly qualified to carry out this work without causing negative impacts on the environment. For these countries, this matter represents a true challenge, requiring you to have financial resources to create capacities and to acquire technologies, that which reality should be made with the support of the developed countries, but that up to now it doesn't stop to be a commitments without in the practice it is materialized in an effective way. The collaboration and the cooperation among the countries in development are also an useful road that should be increased. This work seeks to expose as Cuba it has faced this challenge, presenting the carried out actions, the confronted difficulties and the future actions that will be attacked so that the handling of dangerous waste doesn't constitute an environmental problem to solve

    The specific activity of Ra-226 in drinking water of Camaguey city, Cuba, was measured using the emanometric method. The specific activity of Ra-226 in drinking water ranged from 15 ± 5 mBq.l -1 to 39 ±12 mBq.l -1 . The mean specific activity of Ra-226 was found to be 27 ± 8 mBq.l -1 . No seasonal variation was found. Water samples were collected from the two main sources of drinking water: private wells and governmental water supply system, being the mean specific activities of Ra-226: 25 ± 7 mBq.l -1 and 31 ± 9 mBq.l -1 , respectively. Based upon measured concentrations the age-dependent associated effective doses due to the ingestion of Ra-226, as a consequence of direct consumption of drinking water, have been calculated. For the age interval 1 year to 5 years, the average effective dose was 6,2 μSv.y -1 , and for adults the average effective dose was 5,2 μSv.y -1 . (author)

    Alagille's syndrome or arteriohepatic dysplasia has been described in Cuba in nine patients between nine months and 12 years of age (8 males and one female). Among the clinical features we found five major abnormalities: chronic cholestasis with neonatal jaundice (9/9), peculiar facies (9/9), peripheral pulmonary artery hypoplasia associated with cardiac murmur (6/9), butter-fly-like arch defects (4/9), and posterior embryotoxon (6/7). Two children had a severe xanthomatosis. Laparoscopy showed green hepatomegaly depending on the degree of cholestasis, and only one patient had incipient signs of micronodular cirrhosis. Liver histology showed a paucity of interlobular bile ducts. Survival was of 60%. One patient survived more than 30 years. Four patients died of liver carcinoma (unique report in infants), broncho-pneumonia, acute renal failure, and sudden death respectively. Among the minor features were mental retardation (5/9), a peculiar voice (3/9), growth retardation observed in some of our patients. This is the first report on Alagille's syndrome in Latin America, because so far reports have come only from Europe and North America.

    The ability of communities to respond to the pressures of globalization is an important determinant of community health. Tourism is a rapidly growing industry and there is an increasing concern about its health impact on local communities. Nonetheless, little research has been conducted to identify potential mitigating measures. We therefore took advantage of the 'natural experiment' provided by the expansion of tourism in Cuba, and conducted four focus groups and key informants interviews in each of two coastal communities. Participants expressed concerns about psycho-social impacts as well as occupational and environmental concerns, and both infectious and chronic diseases. A wide array of programs that had been developed to mitigate potential negative were described. Some of the programs were national in scope and others were locally developed. The programs particularly targeted youth as the most vulnerable population at risk of addictions and sexually transmitted infections. Occupational health concerns for workers in the tourism sector were also addressed, with many of the measures implemented protecting tourists as well. The health promotion and various other participatory action initiatives implemented showed a strong commitment to address the impacts of tourism and also contributed to building capacity in the two communities. Although longitudinal studies are needed to assess the sustainability of these programs and to evaluate their long-term impact in protecting health, other communities can learn from the initiatives taken.

    The Center for Radiation Protection and Hygiene (CPHR) has been carrying out from 1987 the individual monitoring of workers occupationally exposed to the ionizing radiations in the Republic of Cuba, excepting those that employ X-rays in diagnostic radiology. In this paper the results of the individual monitoring services during the period 1987-1993 are discussed. For all occupational practices the current system of dose limitation established in the country with 50 mSv as limit of annual dose is satisfied. The distribution in all occupational practices other than nuclear medicine and gamma-therapy is characterized by having more than 95% of the controlled personnel with an effective dose lower than 5 mSv. In the case of nuclear medicine and gamma-therapy more than 80% of the workers were below that dose value. For the practices evaluated in this paper the possibility of assuming the system of dose limitation recommended by ICRP is evident. The evaluations carried out for the introduction of operational quantities H p (0.07) and H p (10) in dose assessment procedure are presented. The expressions obtained during the characterization of the film badge dosemeter, in terms of operational quantities guarantees a deviation of response of the dosemeter with depending upon energies, lower than 20 %.

    Full Text Available Background: hemochromatosis type 1 is an autosomal recessive genetic disorder, which should be diagnosed during its preclinical phase in order to prevent severe organ damage. Objective: to establish the diagnosis of hemochromatosis type 1 in Cuba, and calculate its frequencies in patients with hepatopathies. Methods: an analytic cross-sectional study was conducted including 65 patients with liver disease, who were referred to the laboratory of Molecular Biology of the National Medical Genetics Center by clinical geneticists. A PCR-RFLP analysis was used for detecting the C282Y and H63D mutations in the HFE gene. Results: PCR-RFLP analysis was standardized for the detection of C282Y and H63D mutations. Frequencies of C282Y and H63D mutations in the HFE gene in patients with hepatopathies were 6.3% and 18.2% respectively. Conclusions: molecular diagnosis of C282Y and H63D mutations in the HFE gene causing hemochromatosis type 1 contributed to the identification of 28 carriers in the 65 patients who were studied, as well as a homozygous individual for the H63D mutation, which shows the high prevalence of these mutations in Cuban patients with liver disease.

The event was organized by the hospital itself with the support of the Society of Medical Physics (medical physics section), CEADEN, the Embassy of Japan and the Theragnostic Compounds R&D Center Neuroscience Research Institute Gachon University, Incheon Korea. It was attended by 80 national scientific leaders and with the invaluable presence of Dr. Tatsuo IDO, Emeritus professor of Tohoku University (Sendai, Japan) who presented the results of the scientific papers presented this year in national and international events , referring to the new technologies of molecular imaging and the importance of medical physics in its development. During the meeting the importance of the new technologies of molecular imaging, its undisputed diagnosis intake and medical treatment and the value of human capital struggled to deal with the new technologies, the view that these are only used best when it is understood that they are multidisciplinary systems where each specialist and technical personnel plays an indispensable role. The challenge has medical physics to address these new technologies and the need for changes in the theoretical and practical training in the specialty. These analyzes will be given continuity in the next symposia molecular imaging. (author)

    The San Felipe Hutia, Mesocapromys sanfelipensis, is one of the most endangered species of rodents in the world, and little is known about its ecology, evolution, and ancient distribution. At present, this hutia has been found only in its type locality, Cayo Juan Garcia, a cay in the southwest Cuban insular platform. Here we report for the first time a well preserved fossil skull referred to this species, collected in Cueva del Indio, Mayabeque province, western Cuba. This specimen shows that the modern population of M. sanfelipensis is a marginal relic of its former distribution, a consequence of climatic, eustatic, and neotectonic changes in the last 8 ka years. Also, we reevaluate the cranial characters and measurements that correspond to M. sanfelipensis and found that two of the eight specimens referred to this species and deposited at the Instituto de Ecologia y Sistematica belong to Mesocapromys auritus. Finally, we include six unpublished photos of specimens of M. sanfelipensis captured in 1970 during two expeditions to Cayo Juan Garcia.

    The vertical distribution of Hg and Pb were determined in a sediment core collected from the Sagua estuary (North Cuba) that receives input from the Sagua river, one of the most polluted rivers discharging into the Cuban coastal environment. Depth profiles of metal concentrations were converted to time-based profiles using the 210 Pb dating method and confirmed with the 137 Cs fallout peak. The mean mass accumulation rate was estimated to be 0.17 ± 0.04 g cm -2 y -1 (mean sediment accumulation rate 0.52 ± 0.13 cm y -1 ) and the core bottom was estimated to date back about 130 years. The historical sedimentary record showed a strong enrichment of mercury concentrations in the past decades, caused by the incomplete treatment of industrial wastes from a chlor-alkali plant with mercury-cell technology in the Sagua river basin. Lead fluxes to sediments showed a gradual increase from the 1920s to present, which agrees with a population increase in Sagua la Grande City. Fluxes of both metals have increased the past 25 years, with values reaching a maximum of 0.5 and 3.9 μg cm -2 y -1 for Hg and Pb, respectively.

    Abstract The Cuban fauna of the genus Berosus Leach, 1817 is reviewed based on newly collected material as well as historical and type specimens. Nine species are recognized, including three recorded from Cuba for the first time: Berosus infuscatus LeConte, 1855, Berosus interstitialis Knisch, 1924 (= Berosus stribalus Orchymont, 1946 syn. n.) and Berosus metalliceps Sharp, 1882. Only one of the nine Cuban species, Berosus chevrolati, remains endemic to Cuba, as two other species previously considered as endemic to Cuba are recorded from elsewhere: Berosus quadridens from Mexico and Central America and Berosus trilobus from the Dominican Republic. Notes on biology and Cuban distribution are provided for all nine species. Berosus quadridens Chevrolat, 1863, stat. restit. is removed from synonym with Berosus truncatipennis and considered a valid species. PMID:23794806

    Full Text Available In their oft-cited manifesto, the Martinican Creolists exhort Caribbean people to forego their continuing allegiances to the “mythical shores” of various old worlds, and to affirm instead the “alluvial Creoleness” that binds (or that ought to bind them to each other, and to other communities across the globe with a similar plantation history: “Neither Europeans, nor Africans, nor Asians, we proclaim ourselves Creoles; “[the Creole language] is the initial means of communication of our deep self, or our collective unconscious, of our common genius, and it remains the river of our alluvial Creoleness.” Despite their qualifications – “Creoleness is an open specificity,” for example – they have been chided for simplifying the complicated socio-political histories of the region. Maryse Condé, for example, has noted that the opposition of colonizing French language and resisting Creole language ignores the extent to which plantation heterogeneity and negotiation rendered Creole a language of both “unity and compromise.” On what terms can alluvial relationships that can undercut imperial and diasporic ties be uncovered? What does the idea of a Creole unconscious solidify, restore, revivify, and for whom? In this essay, I am interested in a Jamaican-born novelist’s use of Cuba’s second war of independence in the 1890s to critique Jamaican complacency about British colonialism after the Second World War. Cuba, and a “Creole Latin” world more generally, allows him, on my reading, to proffer hispanophone and francophone plantation histories as a model for anglophone sensibilities in the region. The “Creole Latin” affirmation of nationalism, revolutionary struggle, and strong affective ties to the land and to personal relationships, are uncontaminated by the domineering spirit, legalistic prejudices, bureaucracy and commerce, and negotiated concessions that typify anglophone Protestant modes of life.

    A brown tide bloom of Aureoumbra lagunensis developed in Guantánamo Bay, Cuba during a period of drought in 2013 that followed heavy winds and rainfall from Hurricane Sandy in late October 2012. Based on satellite images and water turbidity measurements, the bloom appeared to initiate in January 2013. The causative species (A. lagunensis) was confirmed by microscopic observation, and pigment and genetic analyses of bloom samples collected on May 28 of that year. During that time, A. lagunensis reached concentrations of 900,000 cells ml -1 (28 ppm by biovolume) in the middle portion of the Bay. Samples could not be collected from the northern (Cuban) half of the Bay because of political considerations. Subsequent sampling of the southern half of the Bay in November 2013, April 2014, and October 2014 showed persistent lower concentrations of A. lagunensis, with dominance shifting to the cyanobacterium Synechococcus (up to 33 ppm in April), an algal group that comprised a minor bloom component on May 28. Thus, unlike the brown tide bloom in Laguna Madre, which lasted 8 years, the bloom in Guantánamo Bay was short-lived, much like recent blooms in the Indian River, Florida. Although hypersaline conditions have been linked to brown tide development in the lagoons of Texas and Florida, observed euhaline conditions in Guantánamo Bay (salinity 35-36) indicate that strong hypersalinity is not a requirement for A. lagunensis bloom formation. Microzooplankton biomass dominated by ciliates was high during the observed peak of the brown tide, and ciliate abundance was high compared to other systems not impacted by brown tide. Preferential grazing by zooplankton on non-brown tide species, as shown in A. lagunensis blooms in Texas and Florida, may have been a factor in the development of the Cuban brown tide bloom. However, subsequent selection of microzooplankton capable of utilizing A. lagunensis as a primary food source may have contributed to the short-lived duration

    Babesia bovis, the most important etiological agent causing bovine babesiosis, is widely distributed in Cuba and affects mainly adult cattle. A survey of the prevalence of the disease in cattle using an ELISA kit (FAO/IAEA) revealed that 34.2% of the animals between 6 and 18 months of age were positive to Babesia bovis, whereas 69.9% on the cattle older than 18 months were positive. Antibodies to Babesia bovis were detected in 96.9% of calves vaccinated with an attenuated Babesia bovis vaccine. A good correlation was found between the results of ELISA kit with those from indirect immunofluorescence and immunoperoxidase tests developed in Cuba. (author)

    An estimate of infant and child mortality in the eastern provinces of Cuba is presented using the Brass method as adapted by Trussell. "Estimations by urban and rural zones are also performed within the provinces studied, and results are compared with those possible to obtain by continuous statistics. Results obtained show that in the eastern [part] of the country Holguin and Guantanamo are the provinces with highest infantile mortality rates, and the lowest rates correspond to Granma, followed by Santiago de Cuba."

    The trace fossil Bichordites monastiriensis is found in early Eocene turbiditic sandstones of the upper-slope deposits from the Capdevila Formation in Los Palacios Basin, Pinar del Río region, western Cuba. The potential tracemakers of B. monastiriensis include fossil spatangoids from the family Eupatagidae. The record of Bichordites in the deposits from Cuba allows to suppose that Eupatagidae echinoids were the oldest potential tracemakers of Bichordites isp. and reinforce the hypothesis that the ichnological record are relevant in envisaging the evolutionary history of the spatangoids.

    A Ga-68 solution was used to calibrate the activity concentration using the double-triple coincidence ratio (TDCR) method of liquid scintillation for the first time in the country. The expanded uncertainty (k = 2) of the concentration of Ga-68 activity in the calibrated solution was equal to 2%. For measurements, the commercial liquid scintillation counter HIDEXTM was used. Samples were prepared by adding between 40 and 50 mg of the radioactive solution to 15 mL of ULTIMAGOLD ™ scintillating cocktail. For the estimation of Ga-68 counting efficiencies in the samples used for the calibration, a FORTRAN program developed by the National Institute of Metrology of France for the magnitudes of ionizing radiation, LNHB, was used. The validation of the method was carried out by the calibration of a standard solution of Na-22, also positronic emitter with similar disintegration scheme to Ga-68. The difference between the concentration of Na-22 activity measured using the TDCR method and the certified reference value traceable to the National Institute of Metrology of the United States (NIST) was 0.15%. With the solution of Ga-68 standardized by the TDCR method the calibration of the secondary standard activity meter, model CAPINTEC CRCTM 15R, was carried out for a geometry of 2R flask with 1mL of radioactive solution. Afterwards, this standard activity meter was calibrated for the measurement of Ga-68 in the geometries of interest in nuclear medicine: Flask 15R with 6 mL of radioactive solution, 2.5 mL syringe with 2 mL of radioactive solution and 5 mL syringe with 2 mL of radioactive solution. The results presented in this paper constitute the necessary metrological support for the introduction of new PET and PET / CT technologies into medical practice in Cuba.

    In the last few years, in the international scene, incidents have been reported due to the presence of radioactive materials in the scrap. This reality has motivated the adoption of measures of radiological security, due to the implications that these incidents have for the public and the environment, as well as for the international trade. Among theses actions is the implementation of the radiological control of scrap, with the additional requirement that this control has to be implemented in the framework of a Quality Management Program.Taking into account the international experience, our institution designed and organized in 2002 a national service for the radiological monitoring of scrap, being the clients the main exporting and trading enterprises of this material in the country. During these years, several contaminated materials have been detected, causing incidents that activated the radiological emergency response system. In this sense, since some years ago, our country has been working in the implementation of a national and ministerial system for facing and mitigating the consequences of accidental radiological situations, conjugating efforts and wills from different national institutions with the leadership of the Center of Radiation Protection and Hygiene (CPHR) and the Center of Nuclear Security (CNSN) in correspondence with the social responsibility assigned to the them. These incidents propitiate to have not only a system of capacity and quick response oriented to limit the exposure of people, to control the sources, to mitigate the consequences of the accident and to reestablish the conditions of normality, but also a previous adequate planning that guarantees the speed and effectiveness of it. In these work the experiences reached by the specialists of the CPHR from Cuba during the occurrence of an incident in the execution of the service of radiological monitoring of scraps are exposed.

    The Meat Processing Center of Santiago is located 13 kilometers from the city of the same name in the National Freeway. There, 61 heads of bovine livestock are sacrificed daily approximately around 325 Kg. of weight average and 197 pigs of 80 kg. of weight average, which has a demurrage average between 2 and 3 days in the corrals of the Meat Processing Center which generates a significant amount of excretes, rumen (food not digested by the bowels), bleed fluff, slops, meat residuals and fatty, as well as tripes, all that which constitutes a waste of a discharge at the present time loads pollutant that besides not taking advantage, for the maintenance of some appropriate norms of hygiene, the Meat Processing Center of meat by products is under the obligation of using big quantities of water, which constitutes an important factor of the elaboration cost. After that, the treatment in the plant and its final discharge in acceptable drains increase the general expenses. The big slaughterhouses can produce waste waters with a biochemical demand of oxygen of five days of 1300 ppm. The treatment of the waste and elimination of the waste waters coming from slaughterhouses and meat processing plants are an economic necessity and of public health. The main objectives of this work were: 1) To calculate the energy potentialities of the residuals of the productions pig, bovine and other residuals to transform them into energy and their effluents like organic fertilizer cleans of pathogen elements, by means of the process of anaerobic fermentation. 2) To Transform the Biomass into energy given by the different economic activities of the entity, taking advantage of the same one in the process. To achieve these results we have used the literature in this respect and the experience that exists in the province of Santiago from Cuba in this direction, as for the use of the residuals for the biogas production and to dedicate it to the cooking of food and the production of electric

    This work shows the results of the radiological surveillance of the environment, carried out by the Center of Environmental Studies from Cienfuegos province, in the central region of Cuba during 1994-2014. the environmental equivalent gamma dose rate was daily measured with a Gamma Tracer GF1588 probe. The activity concentrations of 40 K, 137 Cs and 226 Ra were determined in sugar, milk and bananas, and the activity concentrations and the activity fluxes of 7 Be, 40 K, 137 Cs and 210 Pb were determined in aerosols by means of high resolution gamma spectrometry. The environmental equivalent gamma dose rate showed a constant tendency with 89 nSvh -1 standard deviation; the activity concentrations of 40 K, 137 Cs and 226 Ra in sugar, milk and bananas were very below the action level for radionuclides in general consumption foods, dedicated to the international trade; the activity concentrations of 137 Cs and 226 Ra were below the detection limits. The existence of a fundamental pattern in the annual behavior of the radionuclides in aerosols was demonstrated by means of the multivariate statistical analysis. It was mainly determined by the rains, and it was characterized by a maximum of activity concentration and a minimum of activity flux in January-May; a minimum of activity concentration and a maximum of activity flux in June-October and by a transit period in November-December, with low values in both variables. The general decreasing tendency of the atmospheric 137 Cs and the quick decreasing behavior of the 131 I, coming from the Fukushima accident in Japan were demonstrated. (Author)

    Island populations are vulnerable to introduced pathogens, as evidenced by extinction or population decline of several endemic Hawaiian birds caused by the malaria parasite, Plasmodium relictum (order Haemosporida). We analyzed blood samples from 363 birds caught near Guantánamo Bay, Cuba, for the presence of haemosporidian infections. We characterized parasite lineages by determining nucleotide variation of the parasite's mitochondrial cyt b gene. Fifty-nine individuals were infected, and we identified 7 lineages of haemosporidian parasites. Fifty individuals were infected by 6 Haemoproteus sp. lineages, including a newly characterized lineage of Haem. (Parahaemoproteus) sp. CUH01. Nine individuals carried the P. relictum lineage GRW4, including 5 endemic Cuban Grassquits (Tiaris canorus) and 1 migratory Cape May Warbler (Setophaga tigrina). A sequence of the merozoite surface protein gene from one Cuban Grassquit infected with GRW4 matched that of the Hawaiian haplotype Pr9. Our results indicate that resident and migratory Cuban birds are infected with a malaria lineage that has severely affected populations of several endemic Hawaiian birds. We suggest GRW4 may be associated with the lack of several bird species on Cuba that are ubiquitous elsewhere in the West Indies. From the standpoint of avian conservation in the Caribbean Basin, it will be important to determine the distribution of haemosporidian parasites, especially P. relictum GRW4, in Cuba as well as the pathogenicity of this lineage in species that occur and are absent from Cuba. © 2017 Society for Conservation Biology.

    INTRODUCTION Serological and molecular HIV-1 studies in Cuba have shown very low prevalence of seropositivity, but an increasing genetic diversity attributable to introduction of many HIV-1 variants from different areas, exchange of such variants among HIV-positive people with several coinciding routes of infection and other epidemiologic risk factors in the seropositive population. The high HIV-1 genetic variability observed in Cuba has possible implications for transmission and clinical progression. OBJECTIVE Study genetic variability for the HIV-1 env, gag and pol structural genes in Cuba; determine the prevalence of B and non-B subtypes according to epidemiologic and behavioral variables and determine whether a relationship exists between genetic variability and transmissibility, and between genetic variability and clinical disease progression in people living with HIV/AIDS. METHODS Using two molecular assays (heteroduplex mobility assay and nucleic acid sequencing), structural genes were characterized in 590 people with HIV-1 (480 men and 110 women), accounting for 3.4% of seropositive individuals in Cuba as of December 31, 2013. Nonrandom sampling, proportional to HIV prevalence by province, was conducted. Relationships between molecular results and viral factors, host characteristics, and patients' clinical, epidemiologic and behavioral variables were studied for molecular epidemiology, transmission, and progression analyses. RESULTS Molecular analysis of the three HIV-1 structural genes classified 297 samples as subtype B (50.3%), 269 as non-B subtypes (45.6%) and 24 were not typeable. Subtype B prevailed overall and in men, mainly in those who have sex with men. Non-B subtypes were prevalent in women and heterosexual men, showing multiple circulating variants and recombinant forms. Sexual transmission was the predominant form of infection for all. B and non-B subtypes were encountered throughout Cuba. No association was found between subtypes and

    Highlights: ► Collagen isotope (carbon and nitrogen) based reconstruction of paleodiets. ► Human remains recovered from Canimar Abajo, Matanzas Province, Cuba. ► Individuals consumed marine resource diets supplemented with terrestrial plants. ► Trophic level and isotope shifts for breastfed and weaned infant/juveniles (I/J). ► I/J evidence of weaning through distinct δ 15 N enrichments and δ 13 C depletions. - Abstract: This preliminary study investigates the diet of a population of humans (n = 28) recovered from a shell-matrix site of Canimar Abajo on the Canimar River, Matanzas Province, Cuba. The site is characterized by two cemetery levels separated by a layer of occupation/ritual/midden activity that lasted 1.5 ka. Stable C (δ 13 C) and N (δ 15 N) isotope analysis of human bone collagen samples obtained from individuals (7 infant/juveniles, and 21 adults) from both cemetery levels was conducted in order to reconstruct the diet of these two populations, investigate the relative importance of marine vs. terrestrial resources, and reveal any sex- and age-related distinctions in their food sources. Initial indications suggest that individuals from both cemetery levels consumed diets that were marine resource intensive but also supplemented with varied additions of terrestrial (mostly plant) resources. This supplementation is particularly evident in the later cemetery population. Though there are no significant differences in diet according to sex, there is a trophic level and terrestrial-based shift for breastfed and weaning infant/juveniles. The infant/juveniles showed evidence of being weaned through distinct δ 15 N enrichments and δ 13 C depletions over adult females

    Full Text Available This study seeks to collect the comments and judgements that Humboldt makes about Cuba and evaluate their character. The resulting analysis and interpretation will be undertaken on two different levels: One refers to the information that can be found in his unofficial works, which means the letters Humboldt sent during or shortly after of his visits to Cuba, as well as the diaries he used during his expedition. The other is based on the official works, which include his travel description, his famous Essay on Cuba and his autobiographical text written in 1804. Constrasting these descriptions, we will compare the evaluations of this Prussian traveller elaborated in the moment he visited the island, with the works he wrote 22 years after his return to Europe.

    Full Text Available El uso clínico de la insulina por Banting y Best representa un hito en la historia de las ciencias médicas. Los avances en este campo han sido espectaculares y nuestro país no está ajeno a ellos. Sin embargo, poco se conoce sobre los primeros trabajos realizados por los médicos cubanos en relación con la insulinoterapia, hecho trascendental en la historia de la endocrinología cubana, pero desconocido principalmente para las nuevas generaciones de endocrinólogos. Esta revisión tiene como objetivos destacar la introducción en la clínica moderna de la insulina como un importante suceso en la historiografía médica cubana y divulgar la evolución clínica y el esquema terapéutico aplicado a los primeros casos de diabetes mellitus tratados con insulina en Cuba, así como resaltar el empeño y la capacidad de los profesionales de la salud pioneros en el uso clínico de la insulina en aquellos años, entre los que se destaca el Doctor Octavio Montoro. Para realizar este trabajo fue consultada la bibliografía médica de la época, archivos y otras fuentes. Como resultado se obtuvo que en Cuba se introdujo la insulina en el tratamiento de los pacientes diabéticos en febrero de 1923, por el Doctor Montoro, quien fue reconocido por sus conocimientos médicos y por su vasta cultura. Desempeñó múltiples cargos y recibió numerosas condecoraciones. Se concluyó que Cuba fue uno de los primeros países en el mundo que contó con la insulina como arma terapéutica contra la diabetes. El Doctor Octavio Montoro hizo importantes aportes en la investigación sobre la diabetes, por lo que merece ser considerado, a nuestro juicio, como el padre de la diabetología en nuestro país.The clinical use of insulin by Banting and Best represents a hallmark in the history of medical sciences.

    Full Text Available During the first three decades of the twentieth century, hundreds of thousands of Haitian agricultural laborers arrived in Cuba seeking employment in the expanding sugar industry. Historically, Haitian cane cutters were marginal and occupied the lowest socio-economic status in Cuban society. Until relatively recently, the maintenance of Haitian spiritual beliefs, music, dance, and language in Cuba were associated with rural isolation and poverty. Today however, the continuation of Haitian customs is no longer linked with isolation, but exactly the opposite: performance troupes, heritage festivals, art exhibitions, the circulation of religious specialists, collaborations with research centers and academia, endorsement by music promoters, and the tourism industry. Cubans of Haitian heritage have found innovative ways to transform the abject into the exotic, and are currently gaining a public voice in cultural production, particularly through folkloric performance.

  17. The discipline of ergonomics in Cuba within the occupational health framework: background and trends.

    Science.gov (United States)

    Torres, Yaniel; Rodríguez, Yordán; Viña, Silvio

    2013-01-01

    The concept of ergonomics was introduced in Cuba at the beginning of the 1970s. More than 40 years later, the prevailing approach to workers' health is still generally reactive rather than proactive, despite the commitment of the government to the subject. A factor influencing this issue is, generally, lack of recognition of the benefits of establishing ergonomic principles within most occupational activities. Recent progress to move occupational health practice toward a more preventive approach has been conducted, frequently with international support. The introduction of a set of Cuban standards proposing the necessity of ergonomic evaluations is an example of this progress. The main challenge for Cuban ergonomists is to transfer knowledge to occupational health practitioners in order to be in concordance with basic standards and regulations regarding ergonomics. The article offers a short description of the history of ergonomics and an overview of ergonomics practice in Cuba.

    2002-01-01

    The Ferralsols from Ciego de Avila, Cuba, have a pH near neutrality and very low exchangeable acidity, thus, they are not suitable for direct application of phosphate rock. In laboratory and greenhouse experiments, different P fertilizers were tested in order to assess their agronomic effectiveness through the use of nuclear and conventional methods. The phosphate rocks (PRs) came from different deposits (Higuanojo, La Pimienta and Trinidad de Guedes from Cuba; Riecito, Baja California and North Carolina from other countries). Partial acidulation (PA) of some of these rocks was also evaluated. Trinidad de Guedes PAPRs were found to be highly effective compared to their natural PR when evaluated through dry matter production, P uptake and isotopic parameters. Further field experiments are needed to validate the greenhouse results to enhance the agronomic effectiveness of the local Trinidad de Guedes PR through partial acidulation. (author)

    This paper presents views of Australia, Cuba and South Africa concerned with strengthened safeguards regime. Australia has been involved with the IAEA safeguards system since the first plenary meeting of the Conference on the IAEA Statute in 1956, joined the NPT in 1973 and began concluding bilateral safeguards agreements in 1977. Australia has the greatest respect for the IAEA coordinated efforts started in 1998 to strengthen and integrate the safeguards system. Cuba has always attached special importance to nuclear safeguards activities, recognizing their high priority as well as the important role they have in respect to international disarmament and security. South Africa supports the efforts in strengthening the safeguards activities and remains hopeful that the international community will address the challenges posed by the Trilateral Initiative between Russian federation, USA and IAEA in a mature and cooperative way

    Full Text Available The musicality that highlights Santiago de Cuba as one of its fundamental attractions motivated one of the lines of work of the Escalinata project, focused on communication and promotion of Santiago's heritage. The city treasures several hymns composed in different periods and historical contexts, among them some dedicated to the Virgin of the Charity of the Copper and Santiago Apostle, patron of the city. However, dedicated to the city, Santiago's musical history has revealed the existence of a single anthem, which is why a process of restoration and digitization of its scores began in function of the rescue of this musical composition of the early nineteenth century. This work reveals the process of safeguarding and enhancing the value of this piece of music, considered to be the city's cultural heritage, just 88 years after it was premiered in the Municipal Government of Santiago de Cuba.

    Full Text Available In Cuba, Biosphere Reserves protect and keep natural areas of variable size including one or several forest, scrub or grassland vegetation units, either primary or secondary, also taking into account the various kinds of complex vegetation and communities. The Biosphere Reserve Buenavista, located in Central Cuba, includes several primary vegetation units such as the mangrove forest, sandy coast and rocky coast vegetation, littoral scrub and the dry semi-deciduous, semi-deciduous and gallery forests. Ferns and their allies, gimnosperms and angiosperms were determined and listed in the Reserve and dominant or dominated tree taxa were selected, also listing their standard heights with the ultimate purpose of using them in future reforestation planning if deforestation in some zones occurs.

  2. Racial Geographies, Imperial Transitions: Property Ownership and Race Relations in Cienfuegos, Cuba, 1894–1899

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available This article explores race relations in the provincial city of Cienfuegos, Cuba, during a time of immense political change from 1894 to 1899. In those five years, Cuba was transformed from a Spanish colony struggling for independence to an occupied territory of the United States. This political transformation brought into direct confrontation two models of race relations: one Spanish, characterized by racial integration, and the other American, renowned for Jim Crow segregation. This essay examines the lived significance of this political transformation through interracial property transactions recorded in the notarial protocols of Cienfuegos. The findings suggest that the final war of independence provided opportunities for Afro-descendants to purchase prime properties within the official city bounds. Yet, with US intervention in 1898, a subtle but increasing marginalization of men and women of color from the market in urban property is evident. Lucero contends that this marginalization reflects a shift in race relations due to the American imperial presence.

    While horizontal transmission (human-mosquito-human) of dengue viruses largely determines the epidemiology of the disease, vertical transmission (infected female mosquito- infected offspring) has been suggested as a mechanism that ensures maintenance of the virus during adverse conditions for horizontal transmission to occur. The purpose of this study was to analyze the natural infection of larval stages of Aedes aegypti (Diptera: Culicidae) with the dengue virus (DENV) in Cuba. Here, we report vertical transmission of DENV-3 genotype III in natural populations of Ae. aegypti through RT-PCR detection and serotyping plus sequencing. Our report constitutes the first record of vertical transmission of DENV in Ae. aegypti from Cuba with details of its serotype and genotype. Copyright © 2017 Elsevier B.V. All rights reserved.

    The aerial parts of Lantana camara L. were collected from three different geographical locations: Artemisa (Cuba), Biratnagar (Nepal), and Sana'a (Yemen). The essential oils were obtained by hydrodistillation and analyzed by gas chromatography/mass spectrometry. A cluster analysis of 39 L. camara essential oil compositions revealed eight major chemotypes: β-caryophyllene, germacrene D, ar-curcumene/zingiberene, γ-curcumen-15-al/epi-β-bisabolol, (E)-nerolidol, davanone, eugenol/alloaromadendrene, and carvone. The sample from Cuba falls into the group dominated by (E)-nerolidol, the sample from Nepal is a davanone chemotype, and the sample from Yemen belongs to the β-caryophyllene chemotype. The chemical composition of L. camara oil plays a role in the biological activity; the β-caryophyllene and (E)-nerolidol chemotypes showed antimicrobial and cytotoxic activities. © 2016 Verlag Helvetica Chimica Acta AG, Zürich.

    Despite the effort and commitment of the Cuban government in more of 50 year, there are houses without electricity in remote areas of the Electricity Network. These houses or communities have the promise and commitment of the local and national authorities to help them in improve his life quality. How the houses and communities are remote of the electricity network, the cost to extend the network is considerably high. For that reason, the use of renewable sources in these areas is an acceptable proposal. This article does an analysis to obtain different configurations depending to the number of houses. It do a proposal with the use of the Hydrothermal Carbonization process in the cases where is not feasible introduce different renewable source; a technology new in Cuba, and advantageous taking into consideration the kind of biomass that exist in Cuba. The study of the chemical process of the Hydrothermal Carbonization with the Cuban biomass should be further researched. (full text)

    Following the Earth Summit in 1992, Cuba designed and implemented a variety of programs, administrative structures, and public awareness activities to promote sound environmental management and sustainable development. This came shortly after the fall of the Soviet Union and the strengthening of the US blockade in 1990, which resulted in a 35% drop in Cuban GDP. This period, referred to as the Special Period, witnessed a decrease in many environmentally damaging activities both by choice and by necessity, but also resulted in many decisions to resuscitate the Cuban economy. The purpose of this work was to compare and rank the environmental risks Cuba faced before and during the Special Period (1990-2000) using two Comparative environmental risk assessments (CERAs). To do so, an ecosystem integrity risk assessment matrix was constructed with 42 risk end points. The matrix assessed the risk posed by 17 problem areas including air pollution, water contamination, solid waste sites, pesticides and ecosystem degradation. The risks were calculated using five criteria: area affected, vulnerability of affected population, severity of impact, irreversibility of effect and uncertainty. To construct this matrix, both literature reviews and expert interviews in Cuba were conducted in 2000. The results showed a general decrease in risk scores during the Special Period. Before the Special Period, high risks were posed by: terrestrial degradation and industrial wastewater and sludge, followed by freshwater degradation, surface water stressors, and pesticides. After the Special Period, industrial wastewater and sludge and pesticides were no longer high-risk areas, but municipal wastewater and marine coastal degradation ranked higher than previously. Also, the risk endpoints most stressed after 1990 were affected by activities controlled by the government, such as mining and tourism, and lack of infrastructure. Therefore, the claims that public environmental education is the main

  12. IAEA Director General welcomes Cuba's intention to join the nuclear Non-Proliferation Treaty

    International Nuclear Information System (INIS)

    2002-01-01

    Full text: IAEA Director General Mohamed ElBaradei welcomed Cuba's announcement to accede to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and to ratify the Treaty of Tlatelolco establishing a nuclear-weapon-free zone in Latin America and the Caribbean. He expressed the hope that Cuba will conclude soon a comprehensive safeguards agreement with the Agency, as required under Article III of the NPT. 'With Cuba's intention to become party to the NPT, we have come a step closer to a universal nuclear non-proliferation regime,' Mr. ElBaradei said. Only three countries worldwide with significant nuclear activities now remain outside the NPT. With 188 countries party to the Treaty, the NPT is the most adhered to international agreement after the United Nations Charter and the most widely adhered to multilateral arms control treaty. The NPT makes it mandatory that all non-nuclear-weapon States conclude comprehensive safeguards agreements with the IAEA, and thus put all of their nuclear material under IAEA safeguards. The Director General also welcomed Cuba's ratification of the Tlatelolco Treaty, which completes the process of having all countries in the region of Latin America and the Caribbean as members of the nuclear-weapon-free zone in that region. Mr. ElBaradei said that, 'the Tlatelolco Treaty provides a good model for other regional nuclear-weapon-free zones to follow'. He added that 'universal adherence of all countries in regions having nuclear-weapon-free zone arrangements is important to further strengthen the non-proliferation regime'. (IAEA)

  14. The January 2014 Northern Cuba Earthquake Sequence - Unusual Location and Unexpected Source Mechanism Variability

    On 9 January 2014, a magnitude Mw=5.1 earthquake occurred along the Bahamas-Cuba suture at the northern coast of Cuba revealing a surprising seismic hazard source for both Cuba and southern Florida where it was widely felt. Due to its location, the event and its aftershocks (M>3.5) were recorded only at far distances (300+ km) resulting in high-detection thresholds, low location accuracy, and limited source parameter resolution. We use three-component regional seismic data to study the sequence. High-pass filtered seismograms at the closest site in southern Florida are similar in character suggesting a relatively tight event cluster and revealing additional, smaller aftershocks not included in the ANSS or ISC catalogs. Aligning on the P arrival and low-pass filtering (T>10 s) uncovers a surprise polarity flip of the large amplitude surface waves on vertical seismograms for some aftershocks relative to the main shock. We performed regional moment tensor inversions of the main shock and its largest aftershocks using complete three-component seismograms from stations distributed throughout the region to confirm the mechanism changes. Consistent with the GCMT solution, we find an E-W trending normal faulting mechanism for the main event and for one immediate aftershock. Two aftershocks indicate E-W trending reverse faulting with essentially flipped P- and T-axes relative to the normal faulting events (and the same B-axes). Within uncertainties, depths of the two event families are indistinguishable and indicate shallow faulting (<10 km). One intriguing possible interpretation is that both families ruptured the same fault with reverse mechanisms compensating for overshooting. However, activity could also be spatially separated either vertically (with reverse mechanisms possibly below extension) or laterally. The shallow source depth and the 200-km long uplifted chain of islands indicate that larger, shallow and thus potentially tsunamigenic earthquakes could occur just

    Full Text Available Tanto la Unión Europea como América Latina, e incluso Estados Unidos, han iniciado distintos procesos de diálogo con Cuba. ¿Cuáles lecciones relevantes se pueden extraer de la larga historia canadiense de compromiso con la Revolución Cubana? Este artículo documenta la evolución de las relaciones entre Canadá y Cuba desde la década de 1940, centrándose en sus altibajos desde que se lanzó, a mediados de la década de 1990, una política de «compromiso constructivo ». Se argumenta que este acercamiento (en sus diversas formas no ha tenido mayor influencia en la liberalización de la política cubana. Además, la poca influencia que Canadá pudo haber tenido durante el «Periodo Especial» ha disminuido con la recuperación económica y diversificación de las relaciones exteriores de Cuba en la última década. En ese sentido, los autores concluyen que la estrategia más apropiada para Canadá y otros «actores» es llevar a cabo un acercamiento coordinado y de largo plazo que brinde apoyo a una variedad de procesos endógenos de cambio en Cuba. Una estrategia realista debería incluir diálogo de bajo perfil con el régimen actual, cooperación con un amplio espectro de posibles reformadores dentro y fuera del Estado y apoyo para la realización de cambios sociales más extensos a través del comercio, la inversión extranjera, el turismo así como los intercambios académicos y culturales
