    1977-08-01

    Before 1959 a private individual (Mr. Rene Abularach) is reported to have made an airborne radiometric survey of the Sierra de las Minas and Sierra Madre Ranges. Although many anomalies were detected by this survey, none were verified in the ground survey followup, despite apparently adequate flight control. In 1968 a United Nations Special Fund Mineral Survey Project completed over 1,000 km of carborne radiometric survey with geiger counter readings at 500 m intervals. No anomalies were detected, but background radioactivity for several formations and geologic environments was established. In 1969 the Guatemalan government solicited the IAEA for technical assistance In conducting a preliminary uranium favorability study designed to formulate recommendations for a national radioactive ore prospecting program. A carborne radiometric survey was made of environments theoretically favorable for uranium deposition, with spot geological and radiometric examinations being .conducted in the more favorable areas. All Important mining regions of Guatemala except the leterites and the ultrabasics were visited. No evidence of a uranium province was observed 1n these field investigations and the recommendation was made that the government not embark on a more detailed national prospecting program at that time. At the time of completion of the IAEA-Guatemalan government (GOG) reconnaissance program in 1971, no uranium reserves or resources were known. More recent information on uranium occurrences and resources 1n Guatemala does not appear to be available. Information on more recent uranium reconnaissance than that undertaken during 1971 IAEA-GOG study is lacking. However, in more recent years the country's mineral potential has been generally evaluated with the aid of the UN and ICAITI (Central American Research Institute for Industry). Except for quarry materials, the state owns all minerals. The state has priority on purchase of any mineral production needed for the country

    The people, geography, history, government, economy, defense and foreign relations of Guatemala are reviewed in this background notes series publication by the U.S. State Department. There are 8.4 million Guatemalans, growing at 3.1% annually. Infant mortality rate is 79/1000 and life expectancy is 55 years among the Indian population. The terrain includes both tropical rain forest and hot fertile lowlands, and cooler central highlands. The native Indians are descendants of the Mayans, conquered by the Spanish in the 16th century. Since independence in 1821, Guatemala has endured a succession of dictatorships, military coups, and political violence. The current government, in power since 1986, has the benefit of elections and a constitution. The economy is based on private enterprise, including exports of agricultural commodities and petroleum. The country is self-sufficent in hydroelectric power. It has suffered from economic setbacks and guerrilla insurgencies in recent years, but Guatemala has the resources for diverse agricultural products and tourism.

    Guatemala's area comprises 108,780 square km or 42,000 square miles. The population numbered 9 million in 1990. Ethnic groups include mixed Spanish-Indian races. Spanish and 23 Indian languages are used. Literacy is 52%, the infant mortality rate is 73/1000, and life expectancy is 60 years but only 44 years for Indians. The government is constitutional democratic republic. The total gross domestic product (GDP) was estimated at $10 billion in 1990. US economic assistance amounted to $118 million in FY 1990. Protestantism and traditional Indian religions make up 30% of practiced religion. Since the defeat of the flourishing Mayan civilization by the Spanish in 1523-24 the country's history has been turbulent with a series of dictatorships after independence in 1821. In its recent history Vinicio Cerezo won the 1985 election overwhelmingly, but renewed violence, a failing economy, strikes, corruption, and an inability to deal with infant mortality, illiteracy, and the low quality of health care marked its final years. In 1990 Jorge Serrano was elected in the 1st democratic transition. Negotiations were started with the Guatemalan National Revolutionary Unit to end the violence and respect human rights. An agreement on dialogue was signed in Oslo with the hope of ending one of the oldest insurgencies in the world. The economy started to improve after 1986, and far-reaching reforms could induce rapid growth in coming years especially in agricultural exports. The private sector generates 90% of the GDP. Foreign development assistance has increased: the US has contributed $800 million since 1986. Impediments to faster economic growth are posed by illiteracy and low levels of education, insufficient capital market, and limitations of the infrastructure.

    1999-01-01

    Experiments were conducted from 1994 - 1998 to test the attractiveness of combinations of food-based chemicals for C. capitata (medfly) in Guatemala. Most studies were done in coffee. The 1995 studies, using the FA-2 attractants (ammonium acetate and putrescine) showed that this combination was attractive for females and had potential for use in conjunction with a SIT program. The 1996 studies at three elevations demonstrated that, in general, these attractants, when used in either the Open Bottom Dry Trap (OBDT), Closed Bottom Dry Trap (CBDT), or International Pheromone's McPhail Trap (IPMT) performed better than the Jumbo McPhail trap (JMT) baited with NuLure and borax (NU+B) for capture of feral females. At the high elevation (1400 m), the IPMT with FA-2 and OBDT with FA-2 were best; at the middle elevation (1100 m), the ORDT, IPMT, and CBDT with FA-2 were best; and at low elevations (659 m), the IPMT with FA-2, JMT with NU+B and ORDT with FA-2 were equal in performance. At the middle elevation, using sterile flies, the OBDT with FA-2 worked best. When experiments were carried out in pear, the traps using the FA-2 attractants captured more female flies than the JMT, NU+B, but not significantly more. During the 1997 trials, a third component, trimethylamine was added to the two component lure (FA-3). This attractant was tested in a number of locally produced traps using 2 I soft drink bottles with different color bottoms. The dry versions of the traps contained a yellow sticky insert. All study sites were at low elevation 600 - 650 m, in coffee, testing both sterile and feral flies. With the feral flies during the first phase of the study at finca San Carlos, there were no significant differences between treatments, at finca San Luis, the clear local trap with sticky insert and the green local trap with sticky insert were best, and at finca Valapraiso, the green local trap with yellow sticky insert and yellow local trap with sticky insert captured more flies

    1977-10-01

    Indonesia is a country of south east Asia comprising a large island group extending east-west for over 3000 miles. The geology of Indonesia is fairly well known but is extremely complicated. Successive mountain movements took place around an ancient crustal area. The oldest, of Permian-Triassic age formed northeast Sumatra, northern Java and western Kalimantan. This was followed by the Sumatra orogenesis and finally in Cretaceous and Tertiary times the southern half of Java and the islands as far as New Guinea were formed. Geological studies tend to indicate that the most favourable uranium areas are likely to be in West Sumatra and West Kalimantan. Exploration by the Directorate of Survey and Geology of the National Atomic Energy Agency has been carried out on a small scale since 1961. Exploration concession have been granted to French, German and Japanese organisations. No uranium reserve or resource figures have ever been stated but small occurrences and radioactive anomalies have been found in West and South Sumatra, West and Central Kalimantan and in West Irian. Although the geology of some areas appears to be favourable, little success has attended exploration efforts to date and thus the Speculative Potential is noted as between 1,000 and 10,000 tonnes uranium.

    1977-10-01

    There is no information on production of nuclear raw materials in Burma, although there are some uranium occurrences. Hunting Geophysics Ltd has done some aerial prospecting work in the area of Victoria Point in Southern Burma. All the data collected has been plotted on several maps and issued to various Burmese organizations, with a complete report. The follow-up ground exploration was done by a prospecting party headed by Dr Gjelsvik. The Hunting Geophysics' and Dr Gjelsvik reports are not available in the IAEA. The Raw Materials Division in the Union of Burma Atomic Energy Center commenced operations in 1955. The area of Mogok was selected by U Soo Win, the head of the Division, as most favourable for uranium exploration. The region is mountainous, with heavy forest cover. A ground gamma-ray survey was carried out in Mogok Mineral Belt by two geologists accompanied by two assistants, at a spacing of one km. This work showed monazite in all streams over an area of about 150 sq km and has given a detailed studies led to the discovery of some uraninite and pitchblende in the overburden of an old lode. Based, on these first discoveries the Government of Burma requested assistance from the IAEA and an expert was sent there for a period of one year. His field work was mainly limited in the Mogok Mineral Belt, however some reconnaissance field trips were made in other parts of the country. Dr D L Searle concluded that the Mogok area represents a zone of high temperature mineralization but a lower temperature form of uranium mineralization may have developed along the outer edges of the principal high grade zone. He recommended that the area between the Mogok scarp and the Shweli River be systematically traversed. Uranium bearing minerals in Burma are the following: monazite bearing beach sands near Amherst, Tenasserim; monazite placers from near Momeik, Northern Shan States; uraninte crystals from the gem-gravels around Mogok; a radioactive anomaly in syenite at

    1977-10-01

    The Federal Republic of Austria is situated in the southeastern part of Central Europe. The country covers a total area of 83.350 square kilometers, the population amounts to 7.5 million inhabitants. The geographical features of Austria are dominated by the E-W-trending chain of the Alps (approximately 60% of the country). The northeastern part of the country is formed by the nonalpine mountains and hills of the Bohemian Massif. There are a large depression, the basin of Vienna, as well as parts of the Pannonian basin in the eastern part. The main hydrographic features are characterized by the river Danube and its tributaries. With the exception of a small part in the west of the country, the drainage system of which is directed to the river Rhine, all other rivers are drained by the Danube. The elevations in the Alps reach heights of up to 3 800 m. Many of the E-W striking mountain chains are higher than 2000 to 2500 m. Several major N-S trending passes over the mountains are favourable for the transportation systems (railroads, motorroads) - The kind of land use in Austria is mainly determined by the character of the landscape which is made up of mountains and valleys as well as of depressions in the eastern part of the country. In the lowlands, good farmland is available. At lower and at medium elevations, forests and grassland predominate in the Alps. At higher elevations, the Alps are covered with grasslands; a great part of the rocks has no soil cover, another part is covered by perennial snow and ice.The presence of many uranium occurrences in the Permo-Triassic sediments justifies a detailed survey of these strata. Special studies on the lithology and the formation of uranium in these rocks have been made during the last few years. They should be evaluated to point out new favourable prospective areas. The potential of Uranium which is assumed to be found in Austria is 10,000 - 50,000 t U

    1977-11-01

    The geology of Oman is unlikely to lie favourable for uranium occurrence being mainly of marine sedimentary origin. No exploration for uranium has been reported or is planned. The Speculative Potential is placed in the category of less than 1000 tonnes uranium. (author)

    International Nuclear Information System (INIS)

    1977-11-01

    Sweden, covers an area of approx. 450 000 square kilometers. It has a population of 8 millions. With few exceptions in the northern part the access can be regarded as good. A dense network of motorroads and railroad exists. The results obtained by the exploration works combined with other available geo-information permit a separation of two principal uranium provinces in Sweden. The first one is confined to sediments of Upper Cambrian and Lower Ordovician which appears in Southern Sweden and along the border of the Caledonian mountain range in Central Sweden. The uranium occurrence are stratiform, of blackshale type which occurs in the Peltura zone of Upper Cambrian or they are associated to a phosphatite-bearing unit of Lower Ordovician overlying the Cambrian shale formation. The distribution of uranium in Upper Cambrian rocks is in general dependant on their lithology which itself is related to the paleography. This conditions explain relatively higher uranium content of the shale from Billigen.The potential resources of the province are estimated at about 1 million tonnes uranium. The second uranium province, called Arjeplog-Arvidsjaur, situated immediately south of the Arctic circle, comprises one deposit - Pleutajokk - and a group of more than twenty occurrences of similar characteristics and age (1 700 - 1 800 my.). The results of the past exploration have shown that uranium is present in different types of rocks. Because of the presence of uranium in many of the pegmatites the possibility of the formation of large low grade deposits should be tested. Favourable areas are those regions where the geological conditions are similar to the geology of the Grenville province in Canada or the Damara belt of SW-Africa. Special studies are recommended on this subject

    Maldives, an archipelago consisting of between 1,000 and 2,000 islands and atolls in the Indian Ocean contain only 300 square kilometers and is populated by around 130,000 people who are engaged in raising of copra, fruits, taro, and other agricultural products, and in fishing. There is not now and never has been a mining industry except for quarrying of coral road metal. Geologically the coral islands, based on present geological thinking is not a favourable host or source of uranium, and is therefore assigned a zero potential. (author)

    International Nuclear Information System (INIS)

    1977-12-01

    Iran is on the southern flank of the Alpine-Himalayan mountain system and has within its extensive boundaries rocks ranging from crystalline metamorphics and igneous rocks of Precambrian age to sediments of Tertiary - Pleistocene age, some of which could be considered as potentially favourable for uranium deposits. The search for uranium started about 1959 and in the following years some 40 radioactive anomalies and a small number of uranium occurrences were identified. In 1977 the Atomic Energy Organization of Iran greatly expanded its exploration activities and contracted for 895,000 line kilometres to be flown by three contractors in an aerial spectrometric survey designed to cover almost the two fifths of the whole country. The follow-up of this survey will continue for several years. Purely on the basis of its size (1,648,004 km 2 ), its several favourable host rock areas, its location on the flank of the Alpine-Himalayan system and the relatively small amount of systematic exploration coverage completed to date the Speculative Potential could be placed in the 50,000 - 100,000 tonnes category.

    1976-12-01

    Comparison between the geology of the Philippines and favourable geological environments for uranium in other parts of the world suggests that the Philippine geology is not likely to be favourable for the discovery of uranium. Previous work has been mainly of a reconnaissance type and orientated mainly to checking the existing mining areas for radioactivity. The only occurrence known at the present time is at Larap Mine in the Paracale District of Camarines Norte in Luzon. A magnetite iron ore body operated by Philippines Iron Mines Inc contained certain distinct beds, which, in addition to magnetite also contain copper, molybdenum and iron sulphides and uraninite. It is estimated that 200 short tons U 3 O 8 is contained in 500,000 tons ore grading 0.04% U 3 O 8 at Larap. A number of other largely untested but similar occurrences have also been identified in the Paracale District. A few small occurrences of uranium have recently been identified on the island of Samar. It is suggested that the Speculative Potential of the Philippines may be of the order of 1000 tonnes U 3 O 8 . (author)

    International Nuclear Information System (INIS)

    1977-08-01

    Thailand is a country with an area of 514?000 square kilometres situated in the centre of continental south-east Asia, The geology of Thailand is very varied with sedimentary formations ranging from Cambrian to Quaternary in age and including sandstones, shales, limestones of many varieties. Among the igneous rocks, granites are very important and rhyolites, tuffs diorites, basalts and ultrabasic rocks also exist. Tin is the most important mineral occurrence. Available information on the geology and mineral resources suggests that the country may contain significant resources of radioactive minerals. Favourable potential host types are; 1) uranium and thorium in monazite in beach sands and tin placer deposits; 2) uranium in sandstones, principally in Jurassic sandstones of the Khorat Plateau; 3) uranium in Tertiary lignite deposits; 4) uranium in veins in granites; 5) uranium related to fluorite deposits; 6) uranium in black shales and phosphates. Uranium mineralization in sedimentary rocks at Phu Wieng was discovered in 1970. The area has been radiometrically grid mapped and limited shallow drilling has shown continuity.of the narrow, carbonaceous, conglomeratic sandstone host bed. No uranium reserves or resources can be stated at the present time, but the favourable geology of the Khorat Plateau, the known uranium occurrence and the very small exploration coverage is possibly indicative of a good future potential. The Speculative Potential is estimated to be between 1000 and 10,000 tonnes uranium. (author)

  17. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Israel

    International Nuclear Information System (INIS)

    1977-12-01

    The geology of Israel is relatively simple. Most of the country is underlain by sedimentary rocks of Secondary and Tertiary age. As far as the IAEA is aware no systematic exploration has been done for conventional type uranium deposits. Israel has no uranium deposits, and no high or low-grade uranium ores. However, there are uranium 'sources' which are mainly phosphate rock.Proven phosphate reserves in Israel are estimated at about 220 million tons in five different locations. The average uranium concentration is between 100 and 170 ppm. This makes the uranium content in the proven phosphate reserves of Israel to be about 25,000 tons. Together with the possibility of additional discoveries and on the assumption that the economic conditions for the production of both phosphate and uranium become favourable the Speculative Potential is placed in the 10,000 to 50,000 tonnes uranium category.

    1977-11-01

    Iraq consists of a lowland trough lying between asymmetrical and very different upland massifs to the east, north and west and continuing southeastwards to the Persian Gulf. The region is one of crustal weakness and subsidence with relatively young plastic sedimentary rocks engulfed in downwarped, ancient, rigid and highly resistant blocks. Exploration in the 1954-55 period found some minor radioactive anomalies and very low uranium contents in limestones and phosphates. The results of an aerial radiometric survey in 1973-74 are not known to IAEA. Iraq has no reported uranium resources but there are several favourable formations which warrant a detailed survey. In view of the size of the country and the small amount of systematic exploration carried out up to the present time, the Speculative Potential is considered to lie in the 1,000 to 10,000 tonnes uranium category.

    1978-01-01

    With the exception of the exploration activities in relation with the Beach Sand Project along the eastern Bay of Bengal, no systematic exploration for uranium had been done before December 1976, when a radiometric survey was implemented by the IAEA. As a result of this survey high radioactivity up to 450 cps was detected in placer Tipam deposits, The background of the terrain made up by Tertiary sediments is 160 - 170 cps. An anomaly was found in Kalipur Chara area which coincides with concentration of heavy minerals derived from Tipam Sandstones. Another anomaly was found within a horizon of Tipam sandstone crossing Hari River. An isolated outcrop in the riverbed showed a count rate up to 4 times background. During the follow up work it was found that this steeply dipping mineralized band stretches (with interruptions) over a distance of at least 3km along a strike. Samples collected from three different spils showed concentration of uranium 50, 60 and 140 ppm. The mineralized bed varies in thickness from a few cm to 2 m. It consists of alternating altered and unaltered sandstone. Bangladesh and Australian experts have separated monazite, zircon, ilmenite, rutile and magnetite from local sands at Cox's Bazar, 96 km southeast of Dacca. Radioactive mineral content is around 3,1% and exploitation may be feasible. Concerning the present status of exploration the technical assistance mission of the IAEA in the field of uranium exploration in Bangladesh is continuing with the objective to evaluate uranium potential in Chittongong and Sylhet district. Concerning areas favourable for uranium first priority should be given to areas of Hari River and Kalipur Chara where radioactive anomalies were detected. In general the area covered by Tipam Sandstone appears to be favourable for uranium mineralization. The potential for new discoveries in Bangladesh appears to be not too bad. Speculative potential could be in the order of 1-10,000 tons uranium

    1977-08-01

    About 20 percent of Panama has been covered by airborne radiometric surveys, largely in the Azuero-Petaquilia area. Essentially no ground examinations have been made. About one third of the country remains unmapped. Most of the rest has been examined only in rapid reconnaissance largely by the United Nations and oil companies. Detailed mapping has been confined to the Canal Zone. No uranium deposits or prospects of economic interest are known in Panama. There appears to be no information available on present exploration activities for uranium. Panama has no specific legislation relating to nuclear energy. However, all mineral deposits belong to the state, except for salt and similar materials, and are governed by the mineral resources code. There appears to be only one remote possibility for uranium mineralization in Panama, namely, sandstone-type deposits. Marginal marine and fluvial sediments, such as host sandstone-type deposits elsewhere, are most abundant 1n the lower Cenozoic parts of the Azuero and possibly Bocas del Toro basins and are probably absent or poorly developed in the Darien and Central basin. Rocks with even moderate background uranium concentrations to be leached and deposited in such sediments are confined to the silicic and alkaline Intrusive rocks of the La Yeguada Formation 1n western Panama and possibly the Rio Guayabo stock in the Sierra de Maje of eastern Panama. Only the La Yeguada Formation is extensive enough and near enough to a potential sedimentary ore host to be important. Uranium concentrations have not been measured in this unit but its silicic composition, relatively young age (with respect to other volcanic rocks in Panama) and high ash content suggest that it may have relatively high Teachable uranium content. The best areas for exploration for La Yeguada-derived sandstone-type uranium deposits would be in the Pese formation between Santiago and Chitre in the Azuero basin. Possibly favourable sandstone type exploration ground

    1977-10-01

    Portugal is situated on the western edge of the Iberian Meseta. At present, its reasonably assured reserves are about 7800 t of U (including 1000 t of U at more than 830/lb U 3 O 8 ) and 850 t of U in estimated additional reserves. This potential is divided between vein deposits and deposits located in the peribatholithic schists or enclaved in granite. Two main districts share these reserves - Beira at the centre of the country and Alto Alentejo in the east, approximately at the same latitude as Lisbon. In spite of the considerable prospecting activities authorized by Portugal in the Meseta area, the subject cannot yet be regarded as exhausted. Additional resources may still be located in the horizontal and vertical extensions of the vein mineralizations or schists from the already known deposits or outside the districts containing such deposits. Moreover, certain post-Palaeozoic sedimentary basins exhibit features favourable for the presence of uranium-bearing deposits and therefore deserve to be taken into consideration. However, there are as yet no examples of economic mineralization in such locations in Portugal. All things considered, we considered it reasonable to place Portugal in category No. 3 of the classiffication adopted by BJREP. (author)

    Exploration for mineral deposits in Canada resulted in the discovery of large uranium deposits, such as at Great. Bear Lake, Northwest Territories (1930), in the Elliot Lake area, Ontario (1949); Beaverlodge, Wollaston Lake Fold Belt and Carswell Structure in Saskatchewan (1946-1975) and many uranium occurrences in the Canadian Shield, in the Orogenic Belts and in the Platforms. Uranium output in Canada since 1942 until and including 1976 amounted to 112,000 tonnes U. Reasonably Assured uranium resources as of 1976 amounted to 167,000 tonnes U (at a price up to $40/lb. U 3 0 8 ) and 15,000 tonnes U (at a price more than $40 up to $60/lb. U 3 O 8 ). Estimated Additional uranium resources as of 1976 amounted to 392,000 tonnes U (at a price up to $40/lb. U-Og) and 264,000 tonnes U (at a price more than $40 up to $60/lb. U 3 0 8 ). Possible further potential beyond the above mentioned classes is tentatively estimated to be in the 6th category according to NEA/IAEA favourability classification. (author)

    Physiographically India has a total area of 3,268,010 km 2 in three distinct regions. 1. The Peninsular shield in the south with an area of 823,310 km 2 . 2. The Himalayan mountain system with an area of 1,797,200 km 2 . 3. The Indo-Gangetic alluvial plain with an area of 647,500 km 2 . The three presently recognised major uranium provinces in India are: 1. The Singhbhum uranium province; 2. The Rajasthan uranium province, 3. The Madhya Pradesh uranium province. The Atomic Minerals Division of the Department of Atomic Energy has carried out a vigorous exploration programme since 1949 but despite their efforts a great deal of ground has still to be explored. At present, structurally controlled deposits account for most of the uranium resources of India. Uranium occurrences and deposits have been outlined in (1) Vein type deposits (the Singhbhum belt), (2) Conglomerate (Karnataka and Udaipur area, Raiasthan), (3) Sandstones (Madhra Pradesh and Swaliks, Himachal Pradesh, (4) Others such as carbonatites, marine phosphates, etc, (Mussorrie - Sahasradhara In Uttar Pradesh and Chatterpur-Saucur in Madhya Pradesh), (5) By-product Uranium in copper tailings and beach sands. India's total resources are listed as 52,538 tonnes uranium (68,300 short tons U 3 O 8 ) with additional resources from monazite of 12700 tonnes uranium. In view of the wide geological favourability, the many types of occurrences already known and the vast areas of unexplored ground it is estimated that the Speculative Potential may be between 150,000 and 250,000 tonnes uranium which is Category 5.

    France, with an area of 550,000 km 2 , has been prospecting its territory for uranium for more than 30 years. The proven uranium reserves in all the ore categories defined by the NEA/lAEA are estimated at around 120,000 tU, of which 25,000 tU have already been mined. About 70% of these reserves are associated with granites, while the bulk of the remainder is located in Permian sediments and the last in Paleogene sediments. The prospecting effort has not been distributed equally over French territory. More than half of it - recent orogens and large basins - have been little or very little prospected. On the other hand, the Hercynian massifs and their Upper Paleozoic mantle have been systematically prospected. Nevertheless, even within the latter there is still room for further exploration: extensions of already known mineralizations both laterally and vertically, conventional mineralizations deep down or under a mantle, types of mineralizations not investigated previously (those associated with acid or intermediate vulcanism, peribatholithic shales, alkaline complexes etc.). Of course, in the areas that have not been so well explored, because they appear less favourable, there are still some possibilities, namely, in the areas of recent orogens, mineralizations associated with antemesozoic cores (same types as above) or directly associated with orogenesis (slightly to moderately metamorphic sandstone-phyllitic formations, certain sedimentary formations etc.). As for the large basins, they are capable of containing mineralizations associated with some of their formations (Paleogene of the Basin of Aquitaine etc), but they may also cover workable uranium deposits. It is possible that, in the not to distant future access may be gained to such ores in particular cases. On this basis it does not seem unreasonable to reckon with the discovering of new resources of an order of magnitude between half and the same as those already found. (author)

    1977-08-01

    On invitation of the Nicaraguan Government, the U. S. Atomic Energy Commission conducted a reconnaissance for uranium in March, 1953. Operating and abandoned mines, as well as prospects, formations, contacts, dikes and sills enroute to these mines were tested by scintillometer. Reconnaissance included two mineralized areas exposed in windows within the volcanic belt but did not include the schists and granitic intrusions in the north eastern part of the country. No anomalous radioactivity was detected. No uranium occurrences were discovered during the 1953 reconnaissance and no uranium deposits or prospects are indicated on the metallogenetic map of Central America or in the bibliography of Nicaraguan geology. Information is net available on current exploration in Nicaragua. All subsoil mineral resources besides quarry materials belong to the state. In the interest of national defence, uranium, thorium, lithium and their derivatives, along with certain other mineral substances, may be classified as o f temporary strategic interest , and their exploration or exploitation would then be subject to special laws. The Ministry of Economy may establish permanent or temporary national reserves on which mining activities are essentially precluded. Foreign nationals and corporations may acquire mineral concessions although particular regulations may be applicable to such an acquisition. Exploration of any favourable formations has been hindered by volcanic ash cover in western Nicaragua and dense vegetation in the East. Little geologic work has been done on the Paleozoic metamorphic rocks or Todos Santos Formation of the Northern Highlands. These could possibly show some potential for discovery of uranium as might the alaskites near Siuna. The potential resources of Nicaragua are estimated at less than 1,000 tonnes uranium

    1977-07-01

    Reserves of uranium are located in the north eastern part of Mexico, primarily in the states of Tamaulipas and Chihuahua. Most of the remainder of Mexico's reserves are near the Tamaulipas-Neuvo Leon state border in the Tertiary Frio Formation, where they apparently occur in the types of uranium deposits found in Texas, U.S.A. There are two deposits, La Coma and Buenavista, but nothing has been published on dimensions of the ore bodies. Forty-five miles northeast of Hermosillo, in Sonora state is the Los Amoles district where uranium is found associated with gold and other metals in low-grade deposits on the margins of a Cretaceous batholith. Another occurrence is reported in the mining district of Placer de Guadelupe and Puerto del Aire, about 40-50 km northeast of Chihuahua City, in the state of Chihuahua. Reserves of U 3 O 8 which were published in January 1977 by Nuclear Exchange Corporation of Menlo Park, California, are listed. The government of Mexico has not estimated potential resources. It should be noted that much of Mexico appears favourable for uranium, and only 10 percent has been explored. According to NUEXCO (1977), efforts to find uranium are being increased in an attempt to supply Mexico's nuclear reactor requirements through 1990. Activity is reported to be centered in Tamaulipas and Chihuahua states and to a lesser extent in Nueva Leon, Sonora, Coahuila, and Baja California. Major effort will continue to be placed in Chihuahua state to supply the Penna Bianca mill. Correspondence between favorable geological settings for uranium and the geologic regions of Mexico is reported. Mexico is a country with considerable areas that appear promising for discovery of sandstone, vein, and tuff-related deposits. On the other hand, its potential for Precambrian conglomerate and unconformity-related deposits is limited. Considering these geologic factors, as well as the relatively limited amount of exploration done to date, a guesstimate of speculative

    1977-10-01

    Spain, with an area of 504 748 km''2, occupies a large part of the Iberian Peninsula. At present the country appears to have about 6300 t of reasonably assured uranium reserves and 8500 t of additional estimated reserves (all at less than $30/lb of U 3 O 8 ). Spain has devoted some $33 million to prospecting for uranium since the beginning of such work. Most of the reasonably assured reserves are located in ores impregnating Cambrian schists intersected by Hercynian granites (of so-called 'Iberian type'); a small amount, however, is found in veins in Hercynian granites of the Spanish Meseta. The additional estimated reserves are situated in the peripheral post-Hercynian continental basins of the Meseta. Apart from these classical ores, sub-ores have been identified in Silurian quartzites with low concentrations of uranium associated with refractory minerals, totalling more than 200,000 t of U (at concentrations of a few hundred ppm); there are likewise uranium-bearing Oligocene lignites in the Ebro Basin with some 140,000 t of U. These facts, and also the very wide distribution of uranium in space and time (from the Cambrian to the Miocene!) and the country's favourable geological characteristics, suggest that Spain ought in fact to have large reserves of uranium, a conclusion unfortunately belied by the paucity of the economic reserves identified so far. Two things must be borne in mind, however; firstly, Spain's financial outlay for uranium prospecting up till now represents only a quarter of what has been invested in France, for example, and, secondly, the nature of the mineralised bodies in Spain makes exploration difficult. In conclusion it seems that prospecting both of the Iberian-type deposits in the Meseta region and of the deposits associated with detrital sediments in the peripheral continental basins - especially blind mineralized bodies - should hold out excellent prospects for Spain. Consequently we propose that Spain should be placed at least in

    Ceramic pot filters (CPFs) are an effective means of household water treatment, but the characterization of CPF lifetimes is ongoing. This paper describes a lifetime field study in Guatemala which was made possible by a collaboration between researchers, CPF-using households, and local non-governmental organizations (NGOs). Disinfection data were collected periodically for two years using field coliform enumeration kits as were flow rate data with the assistance of NGO staff. Consumer acceptance was characterized by surveying householders in the four subject villages at the beginning and end of the study. Flow rate data showed that average CPF flow rates decreased below the recommended minimum of 1 L h -1 after 10 months of use; however, the survey results indicated that the consumers were tolerant of the lower flow rates, and it is reasonable to assume that the daily volume of treated water can be readily increased by refilling the CPFs more frequently. Of greater concern was the finding that disinfection efficacy decreased below the recommended bacterial reduction after 14 months of use because it would not be obvious to users that effectiveness had declined. Finally, the follow-up visits by the researchers and the NGO staff appeared to increase consumer acceptance of the CPFs.

    Very little information is available to IAEA on the geology and uranium potential of Syria. In 1975 a contract was awarded to Huntings Geology and Geophysics Ltd by the Ministry of Petroleum and Mineral Resources to carry out a study of the country's mineral resources with particular reference to phosphate uranium, chrome and industrial materials. The results of this survey are not known. Apart from the assumption of some possibility of uranium recovery as a by-product from phosphate production it is assumed that the Speculative Potential is likely to be less than 1000 tonnes uranium.

    Although the Central American HIV epidemic is concentrated in high-risk groups, HIV incidence is increasing in young women. From 2005 to 2007, we conducted a cross-sectional study of pregnant women in a large public hospital and an HIV clinic in Guatemala City to describe risk factors for HIV infection and inform prevention strategies. For 4629 consenting patients, HIV status was laboratory-confirmed and participant characteristics were assessed by interviewer-administered questionnaires. Lifetime number of sexual partners ranged from 1 to 99, with a median (interquartile range) of 1 (1, 2). 2.6% (120) reported exchanging sex for benefits; 0.1% (3) were sex workers, 2.3% (106) had used illegal drugs, 31.1% (1421) planned their pregnancy and 31.8% (1455) experienced abuse. In logistic regression analyses, HIV status was predicted by one variable describing women's behaviour (lifetime sexual partners) and three variables describing partner risks (partner HIV+, migrant worker or suspected unfaithful). Women in our sample exhibited few behavioural risks for HIV but significant vulnerability via partner behaviours. To stem feminization of the epidemic, health authorities should complement existing prevention interventions in high-risk populations with directed efforts towards bridging populations such as migrant workers. We identify four locally adapted HIV prevention strategies.

    A prevalence survey for active trachoma in children aged under 10 years and trichiasis in women aged 40 years and older was carried out in four districts in the Sololá region in Guatemala, which is suspected of still having a trachoma problem. Population-based surveys were undertaken in three districts, within 15 randomly selected communities in each district. In addition, in a fourth district that borders the third district chosen, we surveyed the small northern sub-district, by randomly selecting three communities in each community, 100 children aged under 10 years were randomly selected, and all females over 40 years. Five survey teams were trained and standardized. Trachoma was graded using the World Health Organization simplified grading scheme and ocular swabs were taken in cases of clinical follicular or inflammatory trachoma. Prevalence estimates were calculated at district and sub-district level. Trachoma rates at district level varied from 0-5.1%. There were only two sub-districts where active trachoma approached 10% (Nahualá Costa, 8.1%, and Santa Catarina Costa, 7.3%). Trichiasis rates in females aged 40 years and older varied from 0-3%. Trachoma was likely a problem in the past. Trachoma is disappearing in the Sololá region in Guatemala. Health leadership may consider further mapping of villages around the areas with an especially high rate of trachoma and infection, and instituting trichiasis surgery and active trachoma intervention where needed.

    Self-medication with antibiotics may result in antimicrobial resistance and its high prevalence is of particular concern in Low to Middle Income Countries (LMIC) like Guatemala. A better understanding of self-medication with antibiotics may represent an opportunity to develop interventions guiding the rational use of antibiotics. We aimed to compare the magnitude of antibiotic self-medication and the characteristics of those who self-medicate in two pharmacies serving disparate socio-economic communities in Guatemala City. We conducted a descriptive, cross-sectional study in one Suburban pharmacy and one City Center pharmacy in Guatemala City. We used a questionnaire to gather information about frequency of self-medication, income and education of those who self-medicate. We compared proportions between the two pharmacies, using two-sample z-test as appropriate. Four hundred and eighteen respondents completed the survey (221 in the Suburban pharmacy and 197 in the City Center pharmacy). Most respondents in both pharmacies were female (70%). The reported monthly income in the suburban pharmacy was between $1,250.00-$2,500.00, the city-center pharmacy reported a monthly income between $125.00- $625.00 (p Guatemala City. Additionally, self-medicating respondents were most often women and most commonly self-medicated with amoxicillin. Our findings support future public health interventions centered on the regulation of antibiotic sales and on the potential role of the pharmacist in guiding prescription with antibiotics in Guatemala.

    In this article we take a closer look at resistance to the practice of Environmental Impact Assessment (EIA) in mining and energy projects in Guatemala. Collectivities resisting mining and hydropower projects in Guatemala are increasingly using the evaluations of EIAs conducted by international independent professionals. Reaching out to international experts is facilitated by local communities' engagements in transnational networks bringing together activists, NGOs, scientists, journalists and others. We argue that resistance movements resort to international professionals to challenge the limits imposed on them by the national legislation and institutional arrangements as well as by the way in which EIAs are performed in the country. Further, the engagements in networks that facilitate access to knowledge contribute to strengthen the legitimacy of communities' claims. Challenges to and complaints about EIAs are ways in which affected communities try to reclaim their right to participate in decision-making related to their local environment and the development of their communities. Both complaints about EIAs and the use of transnational networks to attain better participation in decision making processes at local levels, illustrated in this study for Guatemala, are common responses to the advancement of extractive industries and hydropower development across Latin America. The widespread of initiatives to challenge EIAs involving international experts in the region show that EIAs have become a sort of a transnational battleground. - Highlights: • Communities’ opposition to extractive projects is rooted in lack of participation in decision-making, including EIAs • Experts’ evaluations of approved EIAs confirm communities’ claims of poor practices in the public sector • Research presented here shows that local communities linked to transnational networks are able to scale up their demands.

    Full Text Available The aim of this paper is to reveal the nuclei, flows and surfaces generated by tourism in Guatemala that, nowadays, constitute the basis for the promotion of the country in the international market. Following the trend in Central America, and after a long civil war, Guatemala is encouraging the growth of its tourism economy. The starting point of this research is rooted in the fact that there are only a handful of places, distributed over the Guatemalan territory, that articulate the tourist flows (constituted mainly by international visitors and onto which tourism surfaces are being constructed. We assume that this territorial structure is still weak, does not include all areas of the country and it is mostly dependant on regional emitting markets. The context of the territorial structure of tourism in Guatemala suggests that all countries in the region are competing to get access to the international tourism market and that this competition will be decided in favour of those nations that mastermind the administration of their natural and cultural resources. At the end of the text, we comment on the basics of the territorial structure found by our study.

    In invertebrate fisheries, sea urchin harvesting continues to grow with dramatic consequences for benthic ecosystems. The identification of areas with a marked natural recruitment and the mechanisms regulating it is crucial for the conservation of benthic communities and for planning the sustainable harvesting. This study evaluates the spatial distribution and density of recruits of the edible sea urchin Paracentrotus lividus along the Sinis + Peninsula (Sardinia) and explores its significant relationships with the local oceanographic features. Our results reveal that recruitment is favoured in areas with slow currents and high levels of confinement and trapping of the water masses. Analysis of the residual circulation indicates that the presence of local standing circulation structures promotes the sea urchin recruitment process. Our findings emphasize the importance of managing local sea urchin harvesting as a system of populations with their demographic influence mainly dependent on the most important ecological driver that is the recruitment.

    Each year medical providers from wealthy countries participate in short-term medical volunteer work in resource-poor countries. Various authors have raised concern that such work has the potential to be harmful to recipient communities; however, the social science and medical literature contains little research into the perceptions of short-term medical volunteer work from the perspective of members of recipient communities. This exploratory study examines the perception of short-term medical volunteer work in Guatemala among groups of actors affected by or participating in these programs. The researchers conducted in-depth, semi-structured interviews with 72 individuals, including Guatemalan healthcare providers and health authorities, foreign medical providers, non-medical personnel working on health projects, and Guatemalan parents of children treated by a short-term volunteer group. Detailed notes and summaries of these interviews were uploaded, coded and annotated using Atlas.ti (Scientific Software Development GmbH, Berlin) to identify recurrent themes from the interviews. Informants commonly identified a need for increased access to medical services in Guatemala, and many believed that short-term medical volunteers are in a position to offer improved access to medical care in the communities where they serve. Informants most frequently cited appropriate patient selection and attention to payment systems as the best means to avoid creating dependence on foreign aid. The most frequent suggestion to improve short-term medical volunteer work was coordination with and respect for local Guatemalan healthcare providers and their communities, as insufficient understanding of the country's existing healthcare resources and needs may result in perceived harm to the recipient community. The perceived impact of short-term medical volunteer projects in Guatemala is highly variable and dependent upon the individual project. In this exploratory study, project

    Full Text Available The present study was conducted in Naranjo County located in the municipality of Mixco, Guatemala. The water supply source comes from two wells with a maximum flow of 25.24 and 33.44 L·s−1. The main problem with this source is the high arsenic concentration—between 0.1341 and 0.1671 mg·L−1. The aim of this study was to conduct laboratory tests, basic engineering and supervision of the construction and evaluation of an operations plant using two configurations, A (low-rate sedimentation and ceramic filter and B (high-rate sedimentation and clinoptilolite filter, to remove arsenic present in water for human use and consumption. This plant supplies water to Naranjo County in Mixco, Guatemala (5000 inhabitants. First, a laboratory Jar Test was performed to evaluate arsenic removal efficiency. And second, a conventional clarification plant was then built (design flow: 25.24 L·s−1. The best results were achieved with configuration B, with the following reagents and dosage as defined by the laboratory tests: 10 mg L−1 ferric chloride as coagulant; 1.8 mg·L−1 CH-polyfocal as flocculant and 0.4 mg L−1 MIT03 as color removal; 1 mg L−1 sodium hypochlorite as oxidant and adjusting pH to ≈7.0 with sodium hydroxide. Once the plant began operating, the efficiency of the treatment process was evaluated. The maximum elimination efficiencies were obtained 100% for turbidity (0 UTN, 89.54% (3.66 UPt-Co for color and 96.80% (0.005 mg L−1 for arsenic, values that comply with Guatemalan standards.

    Mongolia, a country of 1,525,000 square kilometers, and a population of almost the same number of people is land locked between China and USSR. Historically it's closest ties have been with China, but it is now more closely associated with USSR. Geologically it's complex - most exposed formations are younger than PreCambrian although old exist. Potential for uranium is considered fairly good because the fairly complex geology appears to be favourable both for continental sandstone type deposits and calcretes (less than 50%) and vein type, and other deposits (more than 50$). Considerable effort should be made to obtain additional information related to Mongolian geology. (author)

One can however, make the assumption that geologically, there are probably several areas that contain the combination of favourable host rocks and source.

    To explore conceptions of obstetric emergency care among traditional birth attendants in rural Guatemala, elucidating social and cultural factors. design Qualitative in-depth interview study. Rural Guatemala. Thirteen traditional birth attendants from 11 villages around San Miguel Ixtahuacán, Guatemala. Interviews with semi-structured, thematic, open-ended questions. Interview topics were: traditional birth attendants' experiences and conceptions as to the causes of complications, attitudes towards hospital care and referral of obstetric complications. Conceptions of obstetric complications, hospital referrals and maternal mortality among traditional birth attendants. Pregnant women rather than traditional birth attendants appear to make the decision on how to handle a complication, based on moralistically and fatalistically influenced thoughts about the nature of complications, in combination with a fear of caesarean section, maltreatment and discrimination at a hospital level. There is a discrepancy between what traditional birth attendants consider appropriate in cases of complications, and the actions they implement to handle them. Parameters in the referral system, such as logistics and socio-economic factors, are sometimes subordinated to cultural values by the target group. To have an impact on maternal mortality, bilateral culture-sensitive education should be included in maternal health programs.

    This report is a synthesis of the possibilities of CO 2 storage in the Spanish subsurface. Compilation and analysis of geological information has been carried out, looking at surface and subsurface, in order to make a pre-selection of potential favourable units for CO 2 storage, taking in account that each of this storages needs a confining formation to seal the storage. Before the storage selection, a general description of the great geological units of the Iberian Peninsula is done. Afterwards, borehole logging from petroleum exploration is analysed in these units, formations and areas of interest. The aim is to finally obtain a description of selected units and their possibilities of CO 2 storage. (Author) 17 refs

    Saudi Arabia occupies most of the Arabian Peninsula and has an area of 872,722 sq miles, or 2,260,350 sq km. The ancient Arabian Shield of igneous and metamorphic rocks comprises most of the western third of the country. The shield contains many extinct volcanoes surrounded by lava beds. Sloping eastwards are the newer sedimentary areas in which rich oil fields are found. In Saudi Arabia oil is paramount and less effort has been put into searching for mineral deposits than in other countries of similar size and geology. Pour aerial radiometric surveys have been undertaken and some of the anomalies discovered in the earlier ones were ground checked by an IAEA expert in 1963-64. Two anomalies warranted more detailed work, these were the Jabal Said anomaly in the Central Shield area and the Al Ghrayyat in Wadi Sawawin about 70 miles from the Jordan border. The Jabal Said anomaly consists of a zone of altered rocks consisting largely of pegmatite and pegmatite granite= Allanite, pyrochlore, cyrtolite, xenotime and monazite are the ore minerals,, The deposit was estimated to have 2.2 million tons of ore grading 0.2 - 0.3 percent Nb 2 O 5 and 0.03 - 0,05% U 3 O 8 . The other occurrence at Al Ghrayyat is similar but with much lower grade uranium content. In view of the huge size of Saudi Arabia, the existence of many geologically favourable rock types and the poor coverage by sophisticated uranium exploration techniques, the Speculative Potential is placed between 10,000 and 50,000 Tonnes uranium.

    prospective rocks. The Permian or Triassic granite and Triassic acidic volcanics are possible source rocks for uranium in the Mesozoic sediments, although the uranium levels are unknown. Granitic rocks of similar age, exposed in the western part of Irian Jaya (Rirdshead) are accompanied by radiometric anomalies and are known to contain monazite, allanite, xenotime, zircon, and thorite. Miocene and younger intrusions - principally diorite, tonalite, and granodiorite - in the central range, contain up to 4 ppm U and 16 ppm Th, while Tertiary intrusives in New Britain and the Solomon Islands contain less than 2.5 ppm U and 7 ppm Th. Quaternary volcanics in New Britain and on islands off the North New Guinea coast have low levels of U and Th similar to those of the Tertiary intrusives in the area. Some of the tertiary limestone deposits in Papua New Guinea could be potential host rocks to uranium. The most favourable rock unit is Miocene basinal limestone on the platform; it consists of argillaceous micrite and biomicrite, and calcareous mudstone, and is a source and (locally) a reservoir rock of petroleum. Apart, from the inherent difficulties of exploration of a remote region an added problem is the difficulty of airborne surveying in areas of rugged topography and terrain covered by dense forest. In lowland areas there are the additional problems of permanent water cover, leaching of the surface rocks, and heavy soil cover

    In this article, analytical results will be presented and discussed regarding a selected set of figurines from the ancient Maya settlement of La Blanca in Petén, Guatemala. The objective is to characterize the ceramic material by two analytical complementary techniques: X-ray diffraction (XRD) and total reflection X-ray fluorescence (TXRF). The data obtained by means of both XRD and TXRF were compared and analyzed by multivariate statistical techniques in order to obtain sample groups according to their chemical composition. The results of this archaeometric study have been compared to those that have been obtained through macroscopic characterization by means of the traditional classification system know as Type-Variety. Discordances have been found between the clusters obtained by the Type-Variety classification system and the multivariate classification procedures performed on analytical data. - Highlights: • TXRF and XRD analysis are used in studies of Maya figurines from La Blanca settlement (Guatemala). • Multivariate classification procedures were performed on analytical data to identify figurine groups. • Clustering of analytical data is compared with the traditional Type-Variety classification system

    No information is available on past uranium exploration in El Salvador. The foetallogenic map of Central America (ICAITI, 1970) shows no uranium occurrences, and no descriptions of occurrences are available for this study. Information on current uranium exploration in El Salvador is not available. The 1922 mining code, as amended, covers all minerals, with special rules applicable to phosphates, petroleum and other hydrocarbons. The state owns all minerals, including phosphates, except for salt and other common materials. Mineral and surface rights are distinct. Both citizens and aliens may acquire mineral rights. There is a possibility of uranium potential in the clastic sediments containing interbedded volcanics, particularly where the latter are tuffaceous. These rocks occur chiefly in the north western part of the country and are of limited areal extent. The possibility of uranium occurrences associated with acid volcanics cannot be discounted, but it is difficult to evaluate rocks of this type for uranium with the present state of knowledge. Accordingly, potential resources are estimated at between 0 and 1,000 tonnes uranium

    Most parts of Costa Rica, except for the Quaternary volcanic belt, have neither been studied or mapped in detail. Concerning past exploration limited uranium exploration took place in the late 1960's but details are lacking. No additional information is available. A bibliography of Costa Rican geology (Dengo, 19t>2a) and the metallogenic map of Central America (1CAITI, 1970) do not report any uranium occurrences. Data on current exploration activities for uranium are lacking. Mining is essentially regulated by a 1953 code and a 1964 supplement, but the production and use of radioactive materials are controlled by the Costa Rican Atomic Energy Commission. New raining and petroleum laws reportedly are being considered. Mining rights are available with few restrictions to foreign nationals and corporations. Costa Rica contains no rocks older than Cretaceous. The Mesozoic continental clastic sequences of Honduras and northern Nicaragua do not extend this far south. The massive intrusions of acidic granites and syenites in the Talamanca ranges are probably older than the oldest formations now seen adjacent to them and could not have contributed to their mineralization except through weathering. There may be a faint possibility for uranium deposition in lodes and fracture zones within the granitic rocks, but no such deposits have been reported. Insofar as the sediments are concerned, only the shallow water faces of the marine sediments of the Caribbean coastal region offer the remotest possibilities. The uranium potential of Costa Rica is estimated, at less than 1,000 tonnes

    Up to one half of the population in Africa, Asia and Latin America has little access to high-quality biomedical services and relies on traditional health systems. Medical pluralism is thus in many developing countries the rule rather than the exception, which is why the World Health Organization is calling for intercultural partnerships to improve health care in these regions. They are, however, challenging due to disparate knowledge systems and lack of trust that hamper understanding and collaboration. We developed a collaborative, patient-centered boundary mechanism to overcome these challenges and to foster intercultural partnerships in health care. To assess its impact on the quality of intercultural patient care in a medically pluralistic developing country, we conducted and evaluated a case study. The case study took place in Guatemala, since previous efforts to initiate intercultural medical partnerships in this country were hampered by intense historical and societal conflicts. It was designed by a team from ETH Zurich's Transdisciplinarity Lab, the National Cancer Institute of Guatemala, two traditional Councils of Elders and 25 Mayan healers from the Kaqchikel and Q'eqchi' linguistic groups. It was implemented from January 2014 to July 2015. Scientists and traditional political authorities collaborated to facilitate workshops, comparative diagnoses and patient referrals, which were conducted jointly by biomedical and traditional practitioners. The traditional medical practices were thoroughly documented, as were the health-seeking pathways of patients, and the overall impact was evaluated. The boundary mechanism was successful in discerning barriers of access for indigenous patients in the biomedical health system, and in building trust between doctors and healers. Learning outcomes included a reduction of stereotypical attitudes towards traditional healers, improved biomedical procedures due to enhanced self-reflection of doctors, and improved

    Full Text Available In this article, the author focuses on the field of neo-Mayanity and its current transformations. She analyzes these transformations using a historico-ethnographic approach, which includes two phases. The first one consists in reconstructing the historical development of the “Mayan” category in two different social contexts. The second one focuses on current narrative and imageries produced around this category, stemming from ethnographic fieldwork in Mexico and Guatemala. Since the “2012 phenomenon”, in both countries, the accelerating transnationalization of the religious leaders has triggered a resignification of contents through various logics of rearrangement, innovation, cohabitation and glocalization. Finally, she demonstrates that the variations in the different ethnographies are linked with the religious leaders’ biographies and the modes of signification of the “Mayan” category—influenced by the socio-historical contexts of production.

    Volcan de Fuego, Guatemala, is one of Central America's most active systems. More than one hundred thousand people live within ten kilometres of the summit, many of them in profound poverty. Both the summit region and the volcano's steep sided valleys present significant access challenges, mostly associated with unacceptably high risk. Unmanned aerial vehicles (UAVs) offer the opportunity to observe, map and quantify emissions of tephra, gas, lava and heat flux and, using structure from motion algorithms, model dynamic topography. During recent campaigns, the team have completed observations of changes in the summit morphology immediately prior a paroxysmal eruption, mapped the key drainage systems after the fifth of May 2017 eruption and sampled the plume for tephra and gases using a range of onboard instruments. I will present the group's findings within a broader context of hazard mitigation and physical volcanology, and discuss the future of UAVs in volcano monitoring and research.

    To assess the Water, Sanitation and Hygiene (WASH) access and appropriateness of people with disabilities compared to those without, in Guatemala. A case-control study was conducted, nested within a national survey. The study included 707 people with disabilities, and 465 age- and sex-matched controls without disabilities. Participants reported on WASH access at the household and individual level. A sub-set of 121 cases and 104 controls completed a newly designed, in-depth WASH questionnaire. Households including people with disabilities were more likely to use an improved sanitation facility compared to control households (age-sex-adjusted OR: 1.7, 95% CI 1.3-2.5), but otherwise there were no differences in WASH access at the household level. At the individual level, people with disabilities reported greater difficulties in relation to sanitation (mean score 26.2, SD 26.5) and hygiene access and quality (mean 30.7, SD 24.2) compared to those without disabilities (15.5, 21.7, p<0.001; 22.4, 19.1, p<0.01). There were no differences in different aspects of water collection between people with and without disabilities in this context where over 85% of participants had water piped into their dwelling. Among people with disabilities, older adults were more likely to experience difficulties in hygiene and sanitation than younger people with disabilities. People with disabilities in Guatemala experience greater difficulties in accessing sanitation facilities and practicing hygienic behaviours than their peers without disabilities. More data collection is needed using detailed tools to detect these differences, highlight which interventions are needed, and to allow assessment of their effectiveness.

    The intention of the following study was to describe the interrelationship between villagers, domestic animals and wildlife at the Community Forestry Concession of Uaxactún, Guatemala by means of participatory epidemiological methods. The main focus was generating information regarding different livestock diseases considered important by villagers and their relevance, as well as obtaining knowledge concerning hunting activities and cooking methods to gain a better understanding of the interrelationship of people and animals and the diseases of their animals. For poultry, an overall prevalence of 41% of Newcastle disease was found by means of the ELISA test by antibody detection, chicken being the most affected species in the village. No samples were positive to avian influenza with the HI test. No virus was isolated by means of the tracheal or cloaca swabbing of ducks. All species could be hunted by chance at any time of the year. There was a difference in species hunted between seasons, peccaries being more frequently hunted during the dry season and in contrast, deer and wild avian during the rainy season. Villagers did not consume any raw meat. The cooking methods depended on the species. Stewing was the most favoured method for peccaries, wild birds, tepezcuintle and domestic poultry, whereas grilling was preferable for deer, roasting for armadillos and marinating for pork. According to the generated information, the most important domestic livestock species in the village are chickens and pigs, chickens being the most affected by diseases. No evident health problems on pigs were observed in this study. Hunting was shown as an activity enhanced by poverty and the lack of employment opportunities in the village and was mostly directed at larger species such as deer and peccaries. From the viewpoint of a transmission of zoonoses from animals to humans cooking methods mostly reflected a protective factor as no raw meat was eaten, stews and broths being the most

    Type 2 diabetes is characterized by tissue resistance to the action of insulin, combined with a relative deficiency in insulin secretion. In Guatemala, type 2 diabetes results in significant mortality rates. The low incomes of the indigenous population results in the use of alternative therapies such as medicinal plants to treat the illness. We could not find any previous study related to the use of medicinal plants to treat diabetes in Guatemala. The aim of this work is to determine the most effective plant species used in traditional medicine to treat type 2 diabetes. We performed an ethnopharmacological field study among the Cakchiquels of Chimaltenango to select the most prominent plants used to treat the disease. Type 2 diabetic patients from their community health centers were interviewed using structured questionnaires. Two mathematical tools were used to identify potential plant species: the Disease Consensus Index and the Use Value. International databases, including SCOPUS, PubMed, and Google Scholar, were used to identify whether the plants with the highest scores were known to elicit hypoglycemic effects. After analyzing the data, we can propose the following plants as the most prominent among the Cakchiquels of Chimaltenango to treat type 2 diabetes: Hamelia patens Jacq., Neurolaena lobata (L.) R.Br.ex Cass., Solanum americanum Mill., Croton guatemalensis Lotsy, and Quercus peduncularis Née. The Cakchiquel patients interviewed did not understand type 2 diabetes; however, they associated the onset of their disease with a negative emotion, such as shock, sadness or anger. Despite changes in lifestyle, influences of advertising, the availability of innovative treatments and the use of oral hypoglycemic treatments provided by health facilities serving indigenous communities, the Cakchiquel continue to use medicinal plants as adjunctive treatment. While they are unaware whether the plants can cause additional harm, they consider their consumption

    Full Text Available In low- and middle-income countries (LMICs, where the rates of maternal mortality continue to be inappropriately high, there has been recognition of the importance of training traditional birth attendants (TBAs to help improve outcomes during pregnancy and childbirth. In Guatemala, there is no national comprehensive training program in place despite the fact that the majority of women rely on TBAs during pregnancy and childbirth. This community case study presents a unique education program led by TBAs for TBAs in rural Guatemala. Discussion of this training program focuses on programming implementation, curriculum development, sustainable methodology, and how an educational partnership with the current national health-care system can increase access to health care for women in LMICs. Recent modifications to this training model are also discussed including how a change in the clinical curriculum is further integrating TBAs into the national health infrastructure. The training program has demonstrated that Guatemalan TBAs are able to improve their basic obstetrical knowledge, are capable of identifying and referring early complications of pregnancy and labor, and can deliver basic prenatal care that would otherwise not be provided. This training model is helping transform the role of the TBA from a sole cultural practitioner to a validated health-care provider within the health-care infrastructure of Guatemala and has the potential to do the same in other LMICs.

  3. A study of risk factors associated with the prevalence of Cryptosporidium in villages around Lake Atitlan, Guatemala

    Directory of Open Access Journals (Sweden)

    H. E. Laubach

    Full Text Available Cryptosporidium parvum is an endemic, zoonotic coccidian parasitosis that is highly prevalent in third-world countries where waterborne fecal contamination of food and drink or person-to-person contact with oocysts are the most common methods of transmission of the enteric protozoan. This type of transmission of the parasite made the villages around Lake Atitlan, Guatemala a unique site to compare environmental risk factors with the level of Cryptosporidium infections in the local residents. The study was carried out in two villages, San Antonio Palopo and Santa Catarina Palopo, located in the highlands above the shores of the lake. Smears from stool specimens of patients with gastroenteritis were processed using Kinyoun's modified acid-fast stain and observed with light microscopy. Of the 100 residents examined from the two villages, 32% had Cryptosporidium infections. Female children had the highest prevalence of infection (44% in San Antonio Palopo and 46% in Santa Catarina Palopo, p<0.05, and they also had significantly higher infection rates than males, 50% vs. 17%, respectively. The prevalence rate was not influenced by the season of the year or by the location of the residents. We found differences in prevalence rates due to age and gender, and we suggest that the high infection rates of specific groups are associated with their exposure to the contaminated water supply from Lake Atitlan.

    Rabies in bats is considered enzootic throughout the New World, but few comparative data are available for most countries in the region. As part of a larger pathogen detection program, enhanced bat rabies surveillance was conducted in Guatemala, between 2009 and 2011. A total of 672 bats of 31 species were sampled and tested for rabies. The prevalence of rabies virus (RABV) detection among all collected bats was low (0.3%). Viral antigens were detected and infectious virus was isolated from the brains of two common vampire bats (Desmodus rotundus). RABV was also isolated from oral swabs, lungs and kidneys of both bats, whereas viral RNA was detected in all of the tissues examined by hemi-nested RT-PCR except for the liver of one bat. Sequencing of the nucleoprotein gene showed that both viruses were 100% identical, whereas sequencing of the glycoprotein gene revealed one non-synonymous substitution (302T,S). The two vampire bat RABV isolates in this study were phylogenetically related to viruses associated with vampire bats in the eastern states of Mexico and El Salvador. Additionally, 7% of sera collected from 398 bats demonstrated RABV neutralizing antibody. The proportion of seropositive bats varied significantly across trophic guilds, suggestive of complex intraspecific compartmentalization of RABV perpetuation. PMID:25080103

    Health literacy (HL) is recognized as an important health construct that is correlated with various health-related outcomes, but outside of the United States there is limited HL research available, particularly among youth. This study looked at the HL and harmful health behavior (i.e., substance use) of 210 youth across 10 schools in Guatemala City. Based on results from the Newest Vital Sign (NVS) HL assessment, fewer than one third of youth sampled had adequate HL. Training/education to improve adolescent HL is needed in Guatemala City, and the unique skillset of social workers could be an idea method of reaching at-risk youth.

    Migrant women engaged in precarious employment, such as sex work, frequently face pronounced social isolation alongside other barriers to health and human rights. Although peer support has been identified as a critical HIV and violence prevention intervention for sex workers, little is known about access to peer support or its role in shaping health and social outcomes for migrant sex workers. This article analyses the role of peer support in shaping vulnerability and resilience related to HIV/STI prevention and violence among international migrant sex workers at the Mexico-Guatemala border. This qualitative study is based on 31 semi-structured interviews conducted with international migrant sex workers in the Mexico-Guatemala border communities of Tapachula, Mexico and Tecún Umán and Quetzaltenango, Guatemala. Peer support was found to be critical for reducing social isolation; improving access to HIV/STI knowledge, prevention and resources; and mitigating workplace violence, particularly at the initial stages of migration and sex work. Peer support was especially critical for countering social isolation, and peers represented a valuable source of HIV/STI prevention knowledge and resources (e.g., condoms), as well as essential safety supports in the workplace. However, challenges to accessing peer support were noted, including difficulties establishing long-lasting relationships and other forms of social participation due to frequent mobility, as well as tensions among peers within some work environments. Variations in access to peer support related to country of work, work environment, sex work and migration stage, and sex work experience were also identified. Results indicate that peer-led and community empowerment interventions represent a promising strategy for promoting the health, safety and human rights of migrant sex workers. Tailored community empowerment interventions addressing the unique migration-related contexts and challenges faced by migrant sex

    Full Text Available Abstract Background In Guatemala, diabetes is an emerging public health concern. Guatemala has one of the largest indigenous populations in Latin America, and this population frequently does not access the formal health care system. Therefore, knowledge about the emergence of diabetes in this population is limited. Methods Interview participants (n=23 were recruited from a convenience sample of indigenous adults with type 2 diabetes at one rural diabetes clinic in Guatemala. A structured interview was used to assess knowledge about diabetes and its complications; access to diabetes-related health care and treatment; dietary and lifestyle changes; and family and social supports for individuals living with diabetes. Interviews were supplemented with two group interviews with community leaders and health care providers. Thematic analysis was used to produce insights into diabetes knowledge, attitudes, and practices. In addition, a chart review of the clinic’s electronic medical record identified all adult patients (n=80 presenting in one calendar year for a first-time diabetic consultation. Sociodemographic and clinical variables were extracted and summarized from these records. Results Salient demographic factors in both the structured interview and chart review samples included low educational levels and high indigenous language preference. In the interview sample, major gaps in biomedical knowledge about diabetes included understanding the causes, chronicity, and long-term end-organ complications of diabetes. Medication costs, medical pluralism, and limited social supports for dietary and lifestyles changes were major practical barriers to disease management. Quantitative data from medical records review revealed high rates of poor glycemic control, overweight and obesity, and medication prescription. Conclusions This study provides a preliminary sketch of type 2 diabetes in an indigenous Guatemalan population. Combined qualitative and

    To determine tobacco point of sale advertising prevalence in Guatemala City, Guatemala and Buenos Aires, Argentina. Convenience stores (120 per city) were chosen from randomly selected blocks in low, middle and high socioeconomic neighbourhoods. To assess tobacco point of sale advertising we used a checklist developed in Canada that was translated into Spanish and validated in both countries studied. Analysis was conducted by neighbourhood and store type. All stores sold cigarettes and most had tobacco products in close proximity to confectionery. In Guatemala, 60% of stores had cigarette ads. High and middle socioeconomic status neighbourhood stores had more indoor cigarette ads, but these differences were determined by store type: gas stations and supermarkets were more prevalent in high socioeconomic status neighbourhoods and had more indoor cigarette ads. In poorer areas, however, more ads could be seen from outside the stores, more stores were located within 100 metres of schools and fewer stores had 'No smoking' or 'No sales to minors' signs. In Argentina, 80% of stores had cigarette ads and few differences were observed by neighbourhood socioeconomic status. Compared to Guatemala, 'No sales to minors' signs were more prevalent in Argentina. Tobacco point of sale advertising is highly prevalent in these two cities of Guatemala and Argentina. An advertising ban should also include this type of advertising.

    To describe the distribution of pediatric chronic kidney disease (CKD) in Guatemala, estimate incidence and prevalence of pediatric end-stage renal disease (ESRD), and estimate time to progress to ESRD. This study analyzed the registry of the only pediatric nephrology center in Guatemala, from 2004-2013. Incidence and prevalence were calculated for annual periods. Moran's index for spatial autocorrelation was used to determine significance of geographic distribution of incidence. Time to progress to ESRD and associated risk factors were calculated with multivariate Cox regression. Of 1 545 patients from birth to less than 20 years of age, 432 had chronic renal failure (CRF). Prevalence and incidence of ESRD were 4.9 and 4.6 per million age-related population, respectively. Incidence was higher for the Pacific coast and Guatemala City. The cause of CRF was undetermined in 43% of patients. Average time to progress to ESRD was 21.9 months; factors associated with progression were: older age, diagnosis of glomerulopathies, and advanced-stage CKD at consultation. Prevalence and incidence of ESRD in Guatemala are lower than in other countries. This may reflect poor access to diagnosis. Areas with higher incidence and large proportion of CKD of undetermined cause are compatible with other studies from the geographic subregion. Findings on progression to ESRD may reflect delayed referral.

    Full Text Available OBJECTIVE: To describe the distribution of pediatric chronic kidney disease (CKD in Guatemala, estimate incidence and prevalence of pediatric end-stage renal disease (ESRD, and estimate time to progress to ESRD. METHODS: This study analyzed the registry of the only pediatric nephrology center in Guatemala, from 2004-2013. Incidence and prevalence were calculated for annual periods. Moran's index for spatial autocorrelation was used to determine significance of geographic distribution of incidence. Time to progress to ESRD and associated risk factors were calculated with multivariate Cox regression. RESULTS: Of 1 545 patients from birth to less than 20 years of age, 432 had chronic renal failure (CRF. Prevalence and incidence of ESRD were 4.9 and 4.6 per million age-related population, respectively. Incidence was higher for the Pacific coast and Guatemala City. The cause of CRF was undetermined in 43% of patients. Average time to progress to ESRD was 21.9 months; factors associated with progression were: older age, diagnosis of glomerulopathies, and advanced-stage CKD at consultation. CONCLUSIONS: Prevalence and incidence of ESRD in Guatemala are lower than in other countries. This may reflect poor access to diagnosis. Areas with higher incidence and large proportion of CKD of undetermined cause are compatible with other studies from the geographic subregion. Findings on progression to ESRD may reflect delayed referral.

    This study aimed to assess public attitudes in Japan to the promotion of genomic selection in crop studies and to examine associated factors. We analysed data from a nationwide opinion survey. A total of 4,000 people were selected from the Japanese general population by a stratified two-phase sampling method, and 2,171 people participated by post; this survey asked about the pros and cons of crop-related genomic studies promotion, examined people's scientific literacy in genomics, and investigated factors thought to be related to genomic literacy and attitude. The relationships were examined using logistic regression models stratified by gender. Survey results showed that 50.0% of respondents approved of the promotion of crop-related genomic studies, while 6.7% disapproved. No correlation was found between literacy and attitude towards promotion. Trust in experts, belief in science, an interest in genomic studies and willingness to purchase new products correlated with a positive attitude towards crop-related genomic studies.

    To assess human immunodeficiency virus (HIV) diversity and the prevalence of transmitted drug resistance (TDR) in Guatemala. One hundred forty-five antiretroviral treatment-naïve patients referred to the Roosevelt Hospital in Guatemala City were enrolled from October 2010 to March 2011. Plasma HIV pol sequences were obtained and TDR was assessed with the Stanford algorithm and the World Health Organization (WHO) TDR surveillance mutation list. HIV subtype B was highly prevalent in Guatemala (96.6%, 140/145), and a 2.8% (4/145) prevalence of BF1 recombinants and 0.7% (1/145) prevalence of subtype C viruses were found. TDR prevalence for the study period was 8.3% (12/145) with the Stanford database algorithm (score > 15) and the WHO TDR surveillance mutation list. Most TDR cases were associated with non-nucleoside reverse transcriptase inhibitors (NNRTIs) (83.3%, 10/12); a low prevalence of nucleoside reverse transcriptase inhibitors and protease inhibitors was observed in the cohort (Guatemala. TDR prevalence in Guatemala was at the intermediate level. Most TDR cases were associated with NNRTIs. Further and continuous TDR surveillance is necessary to gain more indepth knowledge about TDR spread and trends in Guatemala and to optimize treatment outcomes in the country.

    2016-03-01

    An international NGO, with financial and managerial support from "partner" communities, established Casas Maternas (birthing facilities) in 3 municipalities in the isolated northwestern highlands of the department of Huehuetenango in Guatemala-an area with high maternal mortality ratio (338 maternal deaths per 100,000 live births). Traditional birth attendants are encouraged to bring patients for delivery at the Casas Maternas, where trained staff are present and access to referral care is facilitated. We conducted a mixed-methods study in San Sebastian Coatán municipality to assess the contribution of 2 Casas Maternas to health facility deliveries among partner and non-partner communities, with particular emphasis on equity in access. We surveyed all women who delivered in the study area between April 2013 and March 2014, the first full year in which both Casas Maternas in the study area were operating. In addition, using purposive sampling, we conducted in-depth interviews with 22 women who delivered and 6 focus group discussions with 42 community leaders, traditional birth attendants, and Casas Maternas staff members. We analyzed the quantitative data using descriptive statstics and the qualitative data with descriptive content analysis. Of the 321 women eligible for inclusion in the study, we surveyed 275 women (14.3% could not be located or refused to participate). Between April 2013 and March 2014, 70% of women living in partner communities delivered in a health facility (54% in a Casa Materna) compared with 30% of women living in non-partner communities (17% in a Casa Materna). There was no statistically significant difference in uptake of the Casa Materna by maternal education and only a weak effect by household wealth. In contrast, distance from the Casa Materna had a pronounced effect. Traditional birth attendants were strong advocates for utilization of the Casa Materna and played an important role in the decision regarding where the birth would take

    1997-02-01

    This news brief relates some new directions, since its inception in 1988, which the Family Welfare Association of Guatemala (APROFAM) will be undertaking during 1996-97. In December 1997, APROFAM restructured its program to include reproductive health services with family planning services. The program will target rural Mayan communities. The program will be working toward service sustainability, due to reduced external support. In October 1996 a new board was established that will focus on marketing, IEC, finance and administration, rural development, and clinical services. Meetings between the new board of directors of APROFAM and JOICFP focused on the use of integrated programs as a model for widespread programming among the rural Mayan population. The integrated program that was implemented by JOICFP was successful in reaching Mayan communities of Solola. This population was difficult to reach with conventional family planning approaches. The integrated program was successful in establishing trust with and participation of the rural Mayans. Activities such as parasite control, skills training, and income generation for women were useful in establishing trust and promoting self-reliance. Integrated programs will refocus on family planning and developing self-reliance. The UNFPA will be conducting an annual internal evaluation as a means of sharing information and deepening understanding of project implementation.

    2005-01-01

    The purpose of this paper is to describe women's work in Maya communities in the Guatemala Highlands, along with some of the trends accompanying the rapid societal change there. Over the course of six years, observations and interviews focused on two specific groups of women. The first were traditional, home-based women, the second, teachers in a primary school. Resulting transcripts and field notes were analyzed by the researchers to identify themes related to the women's perspectives on work, the patterns of their work activities, and the importance of work in their lives. Women who had been interviewed were asked to reflect on the themes identified. All the women engaged in paid work activities and were responsible for obligatory tasks in the home. The traditional group preserved the tradition of weaving, but remained largely illiterate, while the emerging group was literate, but did not learn to weave. Cultural change is both positive and negative, as described by these women. It is important to understand the particular values of the culture, and to recognize that these may not conform to Western (that is to say U.S.) beliefs and practices.

    Hospital de la Familia was established to serve the indigent population in the western highlands of Guatemala and has a full-time staff of Guatemalan primary care providers supplemented by short-term missions of surgical specialists. The reasons for patients seeking surgical care in this setting, as opposed to more consistent care from local institutions, are unclear. We sought to better understand motivations of patients seeking mission-based surgical care. Patients presenting to the obstetric and gynecologic, plastic, ophthalmologic, general, and pediatric surgical clinics at the Hospital de la Familia from July 27 to August 6, 2015 were surveyed. The surveys assessed patient demographics, surgical diagnosis, location of home, mode of travel, and reasons for seeking care at this facility. Of 252 patients surveyed, 144 (59.3%) were female. Most patients reported no other medical condition (67.9%, n = 169) and no consistent income (83.9%, n = 209). Almost half (44.9%, n = 109) traveled >50 km to receive care. The most common reasons for choosing care at this facility were reputation of high quality (51.8%, n = 130) and affordability (42.6%, n = 102); the least common reason was a lack of other options (6.4%, n = 16). Despite long travel distances and the availability of other options, reputation and affordability were primarily cited as the most common reasons for choosing to receive care at this short-term surgical mission site. Our results highlight that although other surgical options may be closer and more readily available, reputation and cost play a large role in choice of patients seeking care.

    1993-01-01

    Since 1990 the project of radioactive and environmental contamination started in Guatemala. Studies about the radioactive contamination levels are made within the framework of this project. Cesium-137 has been an interest radionuclide, because it is a fission product released to the environment by the use of nuclear weapons and nuclear power plants accidents. The sampling consisted in collection of soil and grass in 20 provinces of Guatemala, one point by province, and it was made in 1990. The cesium-137 concentration in the samples, was determined by gamma spectrometry, using an hyper pure germanium detector. The results show the presence of radioactive contamination in soil and grass due to cesium-137, at levels that might be considered as normal. The levels found are not harmful for human health, and its importance is the fact that can be used as reference levels for the environmental radioactivity monitoring in Guatemala

    Full Text Available Abstract Background Overweight prevalence among Guatemalan girls is higher in public than in private schools. Little is known about adolescent girls’ perceptions of the right ways to achieve a healthy weight. This study examines public and private school adolescent girls’ perceptions of a “healthy weight,” and barriers and facilitators to achieving it. Methods We conducted 4 focus groups in public and private schools in Guatemala City with girls from 13 to 15 years old. The discussion guide included open-ended questions and activities aimed at examining perceptions of “healthy weight” and barriers and motivators to achieving it within the school environment. Focus groups were audio-recorded and transcribed. Data analyses followed established methods of content analysis. Results Twenty-eight girls (private school, n = 12; public school, n = 16 of ages ranging from 13.1 to 15.9 years (median, 14, IQR, 13.6–14.9 participated in the study. Girls identified images of thin and fit women as healthy. They cited healthy eating and physical activity as ways to achieve a healthy weight. Within the school environment, barriers to maintaining a healthy weight included a lack of healthy food options and the prioritization of sports for boys over girls. In public schools, facilities were less than optimal; in private schools, girls’ access to facilities was limited. Public school girls stated that their uniforms were inappropriate for exercising. Conclusion Our findings support the need to provide more healthy food options in Guatemalan schools. In addition, physical activity for girls should be promoted and facilities made available for their use.

    Overweight and obesity are emerging at alarming rates in low income women in many countries. Guatemala has the additional burden of a high prevalence of chronic under-nutrition (stunting) in children. The purpose of this paper is to explore the dual burden of infant and child (5-23 months) under-nutrition and maternal over-weight and obesity in the Western Highlands of Guatemala. Anthropometric measures were collected in 446 mother-infant dyads in a metropolitan population of mixed indigenous (Maya) and non-indigenous descent in the Western Highlands of Guatemala. Children were identified as stunted based on a height for age <-2 below the WHO reference median and maternal overweight/obesity defined as a BMI ≥25. Stunted children with an overweight/obese mother were compared to other children who were not stunted and/or who did not have an overweight/obese mother. The prevalences of stunting (38%) and maternal overweight/obesity (45%) were high, but just 17% of the mother and child pairs were dual burden. The socio-demographic characteristics of stunted children were not influenced by maternal overweight or obesity. Policies are needed to address under-nutrition as well as preventing obesity and obesity-related chronic disease risks of stunted children and their mothers.

    Three billion people use solid cooking fuels, and 4 million people die from household air pollution annually. Shifting households to clean fuels, like liquefied petroleum gas (LPG), may protect health only if stoves are consistently used. Few studies have used an implementation science framework to systematically assess "de-implementation" of traditional stoves, and none have done so with pregnant women who are more likely to adopt new behaviors. We evaluated an introduced LPG stove coupled with a phased behavioral intervention to encourage exclusive gas stove use among pregnant women in rural Guatemala. We enrolled 50 women at < 20 weeks gestation in this prospective cohort study. All women received a free 3-burner LPG stove and ten tank refills. We conducted formative research using COM-B Model and Theoretical Domains Framework (TDF). This included thematic analysis of focus group findings and classes delivered to 25 pregnant women (Phase 1). In Phase 2, we complemented classes with a home-based tailored behavioral intervention with a different group of 25 pregnant women. We mapped 35 TDF constructs onto survey questions. To evaluate stove use, we placed temperature sensors on wood and gas stoves and estimated fraction of stove use three times during pregnancy and twice during the first month after infant birth. Class attendance rates were above 92%. We discussed feasible ways to reduce HAP exposure, proper stove use, maintenance and safety. We addressed food preferences, ease of cooking and time savings through cooking demonstrations. In Phase 2, the COM-B framework revealed that other household members needed to be involved if the gas stove was to be consistently used. Social identity and empowerment were key in decisions about stove repairs and LPG tank refills. The seven intervention functions included training, education, persuasion, incentivization, modelling, enablement and environmental restructuring. Wood stove use dropped upon introduction of the

    Mid-level health workers are on the front-lines in underserved areas in many LMICs, and their performance is critical for improving the health of vulnerable populations. However, improving performance in low-resource settings is complex and highly dependent on the organizational context of local health systems. This study aims to examine the views of actors from different levels of a regional health system in Guatemala on actions to support the performance of auxiliary nurses, a cadre of mid-level health workers with a prominent role in public sector service delivery. A concept mapping study was carried out to develop an integrated view on organizational support and identify locally relevant strategies for strengthening performance. A total of 93 regional and district managers, and primary and secondary care health workers participated in generating ideas on actions needed to support auxiliary nurses' performance. Ideas were consolidated into 30 action items, which were structured through sorting and rating exercises, involving a total of 135 of managers and health workers. Maps depicting participants' integrated views on domains of action and dynamics in sub-groups' interests were generated using a sequence of multivariate statistical analyses, and interpreted by regional managers. The combined input of health system actors provided a multi-faceted view of actions needed to support performance, which were organized in six domains, including: Communication and coordination, Tools to orient work, Organizational climate of support, Motivation through recognition, Professional development and Skills development. The nature of relationships across hierarchical levels was identified as a cross-cutting theme. Pattern matching and go-zone maps indicated directions for action based on areas of consensus and difference across sub-groups of actors. This study indicates that auxiliary nurses' performance is interconnected with the performance of other health system actors who

    The STD experiments in Guatemala from 1946-1948 have earned a place of infamy in the history of medical ethics. But if the Guatemala STD experiments were so "ethically impossible," how did the U.S. government approve their funding? Although much of the literature has targeted the failings of Dr. John Cutler, we focus on the institutional context and research ethos that shaped the outcome of the research. After the end of WWII, Dr. Cassius Van Slyke reconstructed the federal research contracts process into a grant program. The inaugural NIH study section recommended approval of the Guatemala STD experiments at its first meeting. The funding and oversight process of the Guatemala research was marked with serious conflicts of interest and a lack of oversight, and it was this structure, as opposed to merely a maleficent individual, that allowed the Guatemala STD experiments to proceed. We conclude that while current research regulations are designed to prevent the abuses perpetrated on the subjects of the Guatemala STD experiments, it takes a comprehensive understanding of research ethics through professional education to achieve the longstanding ideal of the responsible investigator, and ensure ethical research under any regulatory scheme. © 2013 American Society of Law, Medicine & Ethics, Inc.

    Severe physical punishment of children is an important issue in international child health and welfare. This study examines such punishment in Guatemala and El Salvador. Data came from nationally representative surveys of women aged 15-49 and men aged 15-59 residing in Guatemala (2002) and El Salvador (2002-2003). The surveys included questions about punishment experienced during childhood, with response options ranging from verbal scolding to beating. In Guatemala, parents were asked how they disciplined their children; questions allowed them to compare how they were punished in their childhood with how they punished their own children. Bivariate and multivariate analyses are presented. In Guatemala, 35% of women and 46% of men reported being beaten as punishment in childhood; in El Salvador, the figures were 42% and 62%, respectively. In both countries, older participants were relatively more likely than younger participants to have been beaten as children. Witnessing familial violence was associated with an increased risk of being beaten in childhood. In Guatemala, having experienced physical punishment as a child increased the chance that parents would use physical punishment on their own children. Multivariate analyses revealed that women who were beaten in childhood were significantly more likely in both countries to be in a violent relationship. The use of beating to physically punish children is a common problem in Guatemala and El Salvador, with generational and intergenerational effects. Its negative and lingering effects necessitate the introduction of policies and programs to decrease this behavior.

    Waste management is a significant problem in Guatemala, as elsewhere in the developing world. The inappropriate disposal of solid waste produces pollution and places the environment and human health at risk. Environmental risk factors, including inadequate disposal of solid waste, are implicated in 25-30% of disease worldwide with children bearing a disproportionate burden of those diseases. Therefore, economic development which reduces inappropriate disposal of waste and affords economic opportunities may help reduce the global burden of disease on children. In the indigenous highlands of central Guatemala, a community supported non-profit organisation called Long Way Home (http://www.longwayhomeinc.org) is employing alternative construction techniques to build a vocational school complex. The construction of the school from waste materials demonstrates the use and principles of re-purposing materials, helps clean the environment and affords further educational and vocational opportunities. This article will outline the health problems inherent in an indigenous area of a developing country and will offer an alternative solution to reverse environmental risk factors associated with solid waste pollution and also actively improve child health.

  9. Rethinking improved cookstove diffusion programs: A case study of social perceptions and cooking choices in rural Guatemala

    Promoters of improved cookstoves (ICSs) argue they provide the “triple benefits” of improving health outcomes, preserving local ecosystems, and reducing greenhouse gas emissions. The majority of ICS research reveals a strong pro-diffusion bias toward proving these benefits. Few studies have examined ICSs from the adopters' point-of-view. The purpose of this case study was to describe how culture and social perceptions affect the adoption and use of ICSs. Results showed that stoves in this rural Guatemalan community had several layers of practical importance beyond cooking food. Most prominently, household members valued stoves as heat and light sources, and as a social gathering point for families. Most ICS models have been purposely designed in controlled conditions to deliver maximum heating efficiency at the lowest production cost. However, this case study revealed that the fuel-efficient designs sacrificed important functional, social, and cultural needs. Efforts to increase adoption rates of ICSs will be more successful if the macro-level “triple benefits” paradigm is adapted to include functional consumer-centric benefits beyond heating food, such as providing heat and ambient light. Adoption programs should account for the cultural and social needs of users, such as recognizing that stoves often serve as a gathering point for families. - Highlights: • Social, functional, and cultural domains affected improved cookstove adoption rates. • The fuel-efficient designs of improved cookstoves sacrificed important practical needs. • Households valued stoves as heat and light sources, and as a social gathering point for families

  10. Geological-uraniferous favourability of South America

    1984-01-01

    The South American continent includes several metallogenic provinces some of which have excellent uranium possibilities. Basically, two types of lithological complex have contributed to this favourability: the large Precambrian shields covering about 5,500,000 km 2 and the crystalline Hercynian nesocratons with about 300,000 km 2 as source rocks. Only in Argentina and Brazil has continuous uranium exploration in South America been carried out, with moderate budgets, during the last twenty-five years. In the rest of South America the search for uranium has been performed intermittently and with limited resources. However, during recent years interest has increased and more continuous operation has been recorded in some countries (Bolivia, Colombia, Chile, Peru). It can be estimated that only 20% of the favourable areas have been explored fairly intensively in Argentina and Brazil, the two most advanced uraniferous countries. Nevertheless, the uranium possibilities of South America are proved by the resources of 250,000 t U already defined (in Argentina and Brazil) for the category of production cost below US $130/kg U. The speculative uranium potential of the continent was estimated by the International Uranium Resources Evaluation Project as between 770,000 and 1,500,000 t U. Within the South American geostructural framework, five main uraniferous geological areas have been defined on the basis of the geotectonic evolution of the continent, the succession of sedimentary and magmatic processes, and the participation in them of the endogenous and exogenous phases of the uranium geochemical cycle. In this paper the principal uranium metallogenic models occurring in the above five main areas are studied together with the uranium potential of each area. The possibility of uranium recovery from these sources in relation to the respective costs of production is briefly discussed

    In recent years trans-boundary incursions from Petén, Guatemala into Belize's Maya Mountain Massif (MMM) have increased. The incursions are rapidly degrading cultural and natural resources in Belize's protected areas. Given the local, regional and global importance of the MMM and the scarcity of deforestation data, our research team conducted a time series analysis 81 km by 12 km along the Belize-Guatemalan border adjacent to the protected areas of the MMM. Analysis drew on Landsat imagery from 1991 to 2014 to determine historic deforestation rates. The results indicate that the highest deforestation rates in the study area were -1.04% and -6.78% loss of forested area per year in 2012-2014 and 1995-1999 respectively. From 1991 to 2014, forested area decreased from 96.9 % to 85.72 % in Belize and 83.15 % to 31.52 % in Guatemala. During the study period, it was clear that deforestation rates fluctuated in Belize's MMM from one time-period to the next. This seems linked to either a decline in deforestation rates in Guatemala, the vertical expansion of deforestation in Guatemalan forested areas and monitoring. The results of this study urge action to reduce incursions and secure protected areas and remaining forest along the Belize-Guatemalan border.

    This paper reports that government officials have been working on changes to the hydrocarbon law to make it easier for operators to explore. In a reform effort, Minister of Energy and Mines Carlos Hutarte brought a new staff dedicated to spurring oil development into office with him. This includes the Directorate of Hydrocarbons, which held a three-day seminar in Dallas, Texas, to acquaint U.S. firms with new policies. Only one company, Basic Resources International, has been operating in Guatemala over the last year. The firm drilled three onshore wells in 1990 for 16,499 ft, including one oil producer. Two further onshore wells are slated this year. Oil production from 14 active wells out of 16 capable averaged 3,943 bpd, up 8.4% from 1989. Reserves are 191 MMbbl

    One-in-five children in Guatemala is born to a mother aged 15-19 years, which poses social, economic and health risks to both mother and child. In Guatemala, adolescent childbearing is directly associated with education, ethnicity and poverty, which increases vulnerability among Indigenous young women living in poverty. This study examines the context and experiences of adolescent childbearing from the perspectives of young mothers in the Kaqchikel Indigenous ethnic group of Sololá, Guatemala. Data were collected in 19 qualitative in-depth interviews with women who had given birth to one or more children when aged 15 to 19 years. Grounded theory and narrative analysis were used to develop a conceptual framework of the process and influences on childbearing. Four distinct pathways were identified, which were influenced by gender expectations, limited communication about sex and stigma around sex. The study identifies key sociocultural influences that lead to adolescent childbearing and reveals variability within these. Identifying distinct pathways to early childbearing and their influences enables a clearer understanding of potential opportunities to interrupt these pathways with culturally relevant policies and programmes, in particular those that promote gender equality and intergenerational communication about sex.

    Isovaleric aciduria (IVA), propionic aciduria (PA) and methylmalonic aciduria (MMA) are inherited organic acidurias (OAs) in which impaired organic acid metabolism induces hyperammonaemia arising partly from secondary deficiency of N-acetylglutamate (NAG) synthase. Rapid reduction in plasma ammonia is required to prevent neurological complications. This retrospective, multicentre, open-label, uncontrolled, phase IIIb study evaluated the efficacy and safety of carglumic acid, a synthetic structural analogue of NAG, for treating hyperammonaemia during OA decompensation. Eligible patients had confirmed OA and hyperammonaemia (plasma NH3 > 60 μmol/L) in ≥1 decompensation episode treated with carglumic acid (dose discretionary, mean (SD) first dose 96.3 (73.8) mg/kg). The primary outcome was change in plasma ammonia from baseline to endpoint (last available ammonia measurement at ≤18 hours after the last carglumic acid administration, or on Day 15) for each episode. Secondary outcomes included clinical response and safety. The efficacy population (received ≥1 dose of study drug and had post-baseline measurements) comprised 41 patients (MMA: 21, PA: 16, IVA: 4) with 48 decompensation episodes (MMA: 25, PA: 19, IVA: 4). Mean baseline plasma ammonia concentration was 468.3 (±365.3) μmol/L in neonates (29 episodes) and 171.3 (±75.7) μmol/L in non-neonates (19 episodes). At endpoint the mean plasma NH3 concentration was 60.7 (±36.5) μmol/L in neonates and 55.2 (±21.8) μmol/L in non-neonates. Median time to normalise ammonaemia was 38.4 hours in neonates vs 28.3 hours in non-neonates and was similar between OA subgroups (MMA: 37.5 hours, PA: 36.0 hours, IVA: 40.5 hours). Median time to ammonia normalisation was 1.5 and 1.6 days in patients receiving and not receiving concomitant scavenger therapy, respectively. Although patients receiving carglumic acid with scavengers had a greater reduction in plasma ammonia, the endpoint ammonia levels were

    2017-04-01

    In this paper, we combine physical and social science approaches to develop a multi-scale regional framework for natural hazard interactions in Guatemala. The identification and characterisation of natural hazard interactions is an important input for comprehensive multi-hazard approaches to disaster risk reduction at a regional level. We use five transdisciplinary evidence sources to organise and populate our framework: (i) internationally-accessible literature; (ii) civil protection bulletins; (iii) field observations; (iv) stakeholder interviews (hazard and civil protection professionals); and (v) stakeholder workshop results. These five evidence sources are synthesised to determine an appropriate natural hazard classification scheme for Guatemala (6 hazard groups, 19 hazard types, and 37 hazard sub-types). For a national spatial extent (Guatemala), we construct and populate a "21×21" hazard interaction matrix, identifying 49 possible interactions between 21 hazard types. For a sub-national spatial extent (Southern Highlands, Guatemala), we construct and populate a "33×33" hazard interaction matrix, identifying 112 possible interactions between 33 hazard sub-types. Evidence sources are also used to constrain anthropogenic processes that could trigger natural hazards in Guatemala, and characterise possible networks of natural hazard interactions (cascades). The outcomes of this approach are among the most comprehensive interaction frameworks for national and sub-national spatial scales in the published literature. These can be used to support disaster risk reduction and civil protection professionals in better understanding natural hazards and potential disasters at a regional scale.

    Guatemala has the third highest level of maternal mortality in Latin America. Postpartum haemorrhage is the main cause of maternal mortality. In rural Guatemala, most women rely on Traditional Birth Attendants (TBAs) during labour, delivery, and the postpartum period. Little is known about current postpartum practices that may contribute to uterine involution provided by Mam- and Spanish-speaking TBAs in the Western Highlands of Guatemala. a qualitative study was conducted with 39 women who participated in five focus groups in the San Marcos Department of Guatemala. Questions regarding postpartum practices were discussed during four focus groups of TBAs and one group of auxiliary nurses. three postpartum practices believed to aid postpartum uterine involution were identified: use of the chuj (Mam) (Spanish, temazcal), a traditional wood-fired sauna-bath used by Mam-speaking women; herbal baths and teas; and administration of biomedicines. TBAs provide the majority of care to women during childbirth and the postpartum period and have developed a set of practices to prevent and treat postpartum haemorrhage. Integration of these practices may prove an effective method to reduce maternal morbidity and mortality in the Western Highlands of Guatemala. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available Triatoma nitida was found in 14 (0.4% out of 3,726 houses located in six departments across Guatemala, which were surveyed from 1994 to 1998 by the man-hour collection method. Compared to previous information, the distribution of T. nitida in Guatemala has increased from five to nine departments; the species is present in mild climates at altitudes from 960 to 1,500 m. Fourteen percent of the intradomestic T. nitida were infected with Trypanosoma cruzi. The species was often found in conjunction with other triatomines (T. dimidiata and Rhodnius prolixus. The domestic and peridomestic presence of T. nitida in Guatemala was rare, but occasionally this species was colonizing human-made constructions. T. nitida appears to have a low importance as Chagas disease vector in Guatemala, as indicated by its scarce presence in the domestic habitats and defecation patterns. However, it clearly has potential to become a Chagas vector so we recommend an on-going study of the intradomestic presence of T. nitida following the control programs in Guatemala. Morphometric analysis of 47 T. nitida males from three localities showed quantitative differences between the populations, which indicates that geographic distance is an important factor in the structuring of T. nitida populations.

    In the Municipality of Chimaltenango, Guatemala, we sampled groundwater for total inorganic arsenic. In total, 42 samples were collected from 27 (43.5%) of the 62 wells in the municipality, with sites chosen to achieve spatial representation throughout the municipality. Samples were collected from household faucets used for drinking water, and sent to the USA for analysis. The only site found to have a concentration above the 10 μg/L World Health Organization provisional guideline for arsenic in drinking water was Cerro Alto, where the average concentration was 47.5 μg/L. A health risk assessment based on the arsenic levels found in Cerro Alto showed an increase in noncarcinogenic and carcinogenic risks for residents as a result of consuming groundwater as their primary drinking water source. Using data from the US Geological Survey and our global positioning system data of the sample locations, we found Cerro Alto to be the only site sampled within the tertiary volcanic rock layer, a known source of naturally occurring arsenic. Recommendations were made to reduce the levels of arsenic found in the community's drinking water so that the health risks can be managed.

    The most prominent geological, lithological, stratigraphic, orogenic, metallogenetic, palaeogeographic and geochemical features favourable for the concentration of uranium deposits in Bolivia are described. This is a generalized study of the features mentioned above and should provide guidelines for eventual better understanding of the geology of Bolivia in general and that of uranium in particular. The purpose here is to demonstrate rational planning, which should be followed by the determination of favourable areas for uranium exploration, by the Bolivian Nuclear Energy Commission/Comision Boliviana de Energia Nuclear (COBOEN), and to provide basic information for the drawing up of contracts with foreign and/or national organizations interested in investing in uranium exploration.

    2011-12-01

    What's known on the subject? and What does the study add? Most men who are diagnosed with favourable-risk prostate cancer undergo some form of active intervention, despite evidence that treatment will not improve health outcomes for many. The decision to undergo treatment after diagnosis is, in part, related to the inability to precisely determine the long-term risk of harm without treatment. Nevertheless, physicians should consider patient age, overall health, and preferences for living with cancer and the potential side effects of curative treatments, before recommending a management option. This is especially important for older men, given the high level of evidence that those with low-risk disease are unlikely to accrue any benefit from curative intervention. What is known on the subject: Over treatment of favourable-risk prostate cancer is common, especially among older men. What does the study add: A review of the natural history of favourable-risk prostate cancer in the context of choices for management of the disease. • The management of favourable-risk prostate cancer is controversial, and in the absence of controlled trials to inform best practice, choices are driven by personal beliefs with resultant wide variation in practice patterns. • Men with favourable-risk prostate cancer diagnosed today often undergo treatments that will not improve overall health outcomes. • A shared-decision approach for selecting optimal management of favourable-risk disease should account for patient age, overall health, and preferences for living with cancer and the potential side effects of curative treatments. © 2011 THE AUTHOR.

Successfully addressing stunting requires defining the barriers to and opportunities for new behaviour-change initiatives. We undertook a mixed-methods assessment of feeding practices and food purchasing behaviours around infants and young children aged 6-36 months in two rural indigenous Guatemalan communities. We found that most caregivers were aware only of acute forms of child malnutrition and that they greatly underestimated the local prevalence of malnutrition. Despite moderate adherence to exclusive breastfeeding and timing of complementary food introduction, diets had poor diversity and inadequate meal frequency. Furthermore, perceptions of food insecurity were high even in the presence of land ownership and agricultural production. Although fortified foods were highly valued, they were considered expensive. At the same time, proportionally equivalent amounts of money were spent on junk foods or other processed foods by most participants. Biological mothers often lacked autonomy for food purchasing and nutritional decisions because of the power exerted by husbands and paternal grandmothers. Our findings suggest several creative and community-based programming initiatives including education about the acute vs. chronic malnutrition distinction, engaging landowners in discussions about domestic food consumption, engaging with caregivers to redirect funds towards fortified foods rather than junk food purchases and directing behaviour-change initiatives towards all household stakeholders. © 2014 John Wiley & Sons Ltd.

    Public health regulations practices surrounding sex work and their enforcement can have unintended consequences for HIV and sexually transmitted infection (STI) prevention and care among sex workers. This analysis was based on qualitative in-depth (n = 33) and focus groups interviews (n = 20) conducted with migrant female sex workers in Tecún Umán and Quetzaltenango, Guatemala, and explored the implementation of sex work regulations and related consequences for HIV prevention and care among migrant sex workers. Sex work regulations were found to have health-related benefits (e.g., access to HIV/STI testing) as well as negative impacts, such as abuse by police and harassment, detention/deportation of migrant sex workers. Whereas public health regulations may improve access to HIV/STI testing, their implementation may inadvertently jeopardize sex workers' health through unintended negative consequences. Non-coercive, evidence-based public health and sex work policies and programs are needed to expand access to HIV/STI prevention and care among migrant sex workers, while protecting their dignity and human rights.

    Hypertension (HT) epidemiological studies in developing regions of the world like rural Guatemala are lacking. A sample size of 1104 subjects (552 females, all 18 years or older) was obtained through quota and geographical clustering in the entire Department of Sololá, Guatemala. Descriptive statistics and logistic regression were used. Average systolic, diastolic, and mean arterial pressures were significantly higher in men compared with women (116.24 vs 113.80 mm Hg, 75.24 vs 72.69 mm Hg, and 88.91 vs 86.39 mm Hg, respectively; all with P Guatemala. Significant associations are found between gender, age ≥55 years, and increased WC but not with an increased BMI in this population. © The Author(s) 2014.

    Cardiovascular disease contributes substantially to the non-communicable disease (NCD) burden in low-income and middle-income countries, which also often have substantial health personnel shortages. In this observational study we investigated whether community health workers could do community-based screenings to predict cardiovascular disease risk as effectively as could physicians or nurses, with a simple, non-invasive risk prediction indicator in low-income and middle-income countries. This observation study was done in Bangladesh, Guatemala, Mexico, and South Africa. Each site recruited at least ten to 15 community health workers based on usual site-specific norms for required levels of education and language competency. Community health workers had to reside in the community where the screenings were done and had to be fluent in that community's predominant language. These workers were trained to calculate an absolute cardiovascular disease risk score with a previously validated simple, non-invasive screening indicator. Community health workers who successfully finished the training screened community residents aged 35-74 years without a previous diagnosis of hypertension, diabetes, or heart disease. Health professionals independently generated a second risk score with the same instrument and the two sets of scores were compared for agreement. The primary endpoint of this study was the level of direct agreement between risk scores assigned by the community health workers and the health professionals. Of 68 community health worker trainees recruited between June 4, 2012, and Feb 8, 2013, 42 were deemed qualified to do fieldwork (15 in Bangladesh, eight in Guatemala, nine in Mexico, and ten in South Africa). Across all sites, 4383 community members were approached for participation and 4049 completed screening. The mean level of agreement between the two sets of risk scores was 96·8% (weighted κ=0·948, 95% CI 0·936-0·961) and community health workers showed

    Violence against Women (VaW) has come to be recognized as a serious human rights abuse with important consequences not only for women but for whole societies. Since VaW has several manifestations, it is possible to differentiate among different types of violence. In this article, a broad theoretical framework with different dimensions of gender violence was adapted to a Latin American social and cultural context to measure three out of the five main types of violence: economic violence, emotional psychological violence, and coercive control. The goal of this article is to provide empirical evidence to determine whether access to microfinance services plays a role in reducing VaW. To this end, we designed and performed a cross-sectional study with a treatment and a control group in rural Guatemala. A sample of 883 rural women in the "Altiplano" area of Guatemala (448 women with microfinance services and 435 without) was surveyed from May to November 2012. The results of the bivariate logistic regression showed evidence of association between access to microfinance services and reduction of VaW. After adjusting for covariates, global, economic, and emotional psychological violence maintained a negative and statistically significant association with microfinance, while only coercive control showed no statistical association with microfinance services. Access to microcredits showed a very clear relationship to reducing economic and emotional violence but not coercive control, a factor that may be determined by social and cultural norms. In contrast to Status Inconsistency Theory, which has been tested primarily in Asia, our study of Guatemala showed that increased status and economic independence of women due to their participation in microfinance services reduced VaW.

    Full Text Available Desde una perspectiva de la sociología del conocimiento de Karl Mannheim se puede comprender el estado del arte de los estudios de pobreza en Guatemala en un escenario entre 1980 y 2004. La justificación del trabajo se debe a la ausencia de una investigación que trate de entender el desarrollo del tema en las Ciencias Sociales en Guatemala y que demuestre su importancia a través de experiencias teóricas y metodológicas. Se puede decir que la investigación sobre la pobreza no ha sido sistemática ni continua debido al proceso social y político que ha vivido el país, no obstante se afirma con toda certeza que existe un corpus bibliográfico heterogéneo y considerable entre 1980-2004. La investigación tuvo como objetivo realizar un balance de las tendencias teóricas y metodológicas de los estudios en los últimos 20 años. Debo apuntar que la bibliografía sobre pobreza es bastante amplia e inevitablemente mereció seleccionar una muestra de los trabajos más representativos e innovadores, no sólo en las dos décadas analizadas, sino también en sus temas. No se puede entender los estudios de pobreza alejados de la Ciencias Sociales y de los procesos históricos, políticos, económicos y sociales de Guatemala y la relación con otros campos de conocimiento en Centroamérica y América Latina.From the perspective of Karl Mannheim's sociology of knowledge, it is possible to understand the state of the art of poverty studies in Guatemala between 1980 and 2004. This work is justified by the lack of investigations looking into the development of Social Sciences in Guatemala and it demonstrates its importance through theoretical and methodological experiences. Investigation on poverty can be said to have been neither systematic nor continued, due to the social and political process the country has undergone. Nevertheless, it can also be sustained that there is a heterogeneous and considerable bibliographic corpus between 1980-2004. This

    Based on the present knowledge of Brazilian Precambrian geology, an attempt is made to divide Precambrian rocks into different regions according to their favourability criteria for uranium concentrations. Paleozoic and Mesozoic occurrences are also mentioned. They are mainly associated with large sedimentary basins. Brazilian uranium occurrences can be grouped into the following environments: (1) Metaconglomerates; (2) Metasomatic rocks (associated with albitization); (3) Vein type; (4) Sandstone type and (5) Intrusive alkalic rock. Upper Proterozoicas folding regions related to mobile belts and large Precambrian unconformities are good targets for uranium exploration in Brazil. (Author) [pt

    Full Text Available The purpose of this paper is to investigate and re-estimate the effects of breastfeeding patterns, women's nutritional and health status, and energy expenditure on the timing of resumption of postpartum fecundability (i.e. resumption of postpartum menses using all the relevant information in the Instituto de Nutrición de Centroamérica y Panamá longitudinal study and a more adequate estimation procedure (hazard models. The data used in this study come from a Longitudinal Study carried out in Guatemala between 1967 and 1979. In this article we use a multi-state hazard model that recognizes different pathways and states in the process of returning to the postpartum fecundability. The model relies on the existence of five states (fully breastfeeding, partial breastfeeding, weaning, infant mortality and menses. It also includes explicitly maternal nutrition and women's energy expenditure as strategic elements of the model. The study shows that the estimated effects of breastfeeding patterns, maternal nutrition and women's work patterns (energy expenditure on resumption of fecundability in rural Guatemala are strong and significant. The contribution of this paper is to show that application of hazard models with multiple states provides estimates that are consistent with hypotheses relating lactation patterns, maternal nutritional status and maternal external stressors to processes that accelerate (decelerate resumption of normal menstrual cycles.

    Full Text Available Guatemala is characterized by low contraceptive use rates and one of the highest fertility rates in the Western Hemisphere. These rates are particularly extreme for the poorest segment of the population and for the indigenous population. The purpose of this research is to enhance understanding of the modern contraceptive revolution in Guatemala through identification of the segments of the Guatemalan population at most need for contraceptive and family planning services. Using the most recently available survey data, the 2002 Reproductive Health Survey data set (RHS, classification trees will be used to determine the women with greatest need for reproductive health services. The results highlight the persistent marginalization of the poor and the indigenous and provide further insight into the impact of education, place of residence and couple characteristics on contraceptive use and intent.

    Full Text Available Despite its biological wealth, current knowledge on the macromycetes inhabiting Guatemala is scant, in part because of the prolonged civil war that has prevented exploration of many ecological niches. We provide a preliminary literature–based checklist of the macrofungi occuring in the various ecological regions of Guatemala, supplemented with original observations reported here for the first time. Three hundred and fifty species, 163 genera, and 20 orders in the Ascomycota and Basidiomycota have been reported from Guatemala. Many of the entries pertain to ectomycorrhizal fungal species that live in symbiosis with the several Pinus and Quercus species that form the extensive pine and mixed forests of the highlands (up to 3600 m a.s.l.. As part of an ongoing study of the ethnomycology of the Maya populations in the Guatemalan highlands, we also report on the traditional knowledge about macrofungi and their uses among native people. These preliminary data confirm the impression that Guatemala hosts a macrofungal diversity that is by no means smaller than that recorded in better studied neighboring Mesoamerican areas, such as Mexico and Costa Rica.

  9. Four arguments in favour of nuclear power

    International Nuclear Information System (INIS)

    Pearce, D.

    1994-01-01

    The first argument in favour of nuclear power is scarcity of energy supplies. In about 40 years time, the world will face shortages of natural gas, oil and uranium. Recoverable reserves of coal are very great, but coal creates the highest environmental damage. A balanced portfolio is the second argument. If all energy sources are potentially scarce, then all energy sources must be developed, subject to environmental impact. This leads to the third argument in support of nuclear power, its expansion would contribute to combating the risk of global warming as indeed would the expansion of renewable sources and other low carbon technologies. Fourthly, nuclear power can make a significant contribution to the control of acidic emissions. While nuclear power is not without its own problems of risk, liability and public acceptance, it has some clear advantages over other fuels. It has, at the very least, to be a substantial part of the transitional phase towards a renewable energy world. (UK)

    Guatemala is a developing country in Central America with a high burden of HIV and endemic fungal infections; we attempted to estimate the burden of serious fungal infections for the country. A full literature search was done to identify epidemiology papers reporting fungal infections from Guatemala. We used specific populations at risk and fungal infection frequencies in the population to estimate national rates. The population of Guatemala in 2013 was 15.4 million; 40% were younger than 15 and 6.2% older than 60. There are an estimated 53,000 adults with HIV infection, in 2015, most presenting late. The estimated cases of opportunistic fungal infections were: 705 cases of disseminated histoplasmosis, 408 cases of cryptococcal meningitis, 816 cases of Pneumocystis pneumonia, 16,695 cases of oral candidiasis, and 4,505 cases of esophageal candidiasis. In the general population, an estimated 5,568 adult asthmatics have allergic bronchopulmonary aspergillosis (ABPA) based on a 2.42% prevalence of asthma and a 2.5% ABPA proportion. Amongst 2,452 pulmonary tuberculosis patients, we estimated a prevalence of 495 for chronic pulmonary aspergillosis in this group, and 1,484 for all conditions. An estimated 232,357 cases of recurrent vulvovaginal candidiasis is likely. Overall, 1.7% of the population are affected by these conditions. The true fungal infection burden in Guatemala is unknown. Tools and training for improved diagnosis are needed. Additional research on prevalence is needed to employ public health measures towards treatment and improving the reported data of fungal diseases.

    In this article, we report the current surgical approach to gallbladder disease at a major referral hospital in rural Guatemala. Complications in a cohort of patients undergoing open versus laparoscopic cholecystectomy were catalogued. We reviewed cholecystectomies performed by surgeons at the Hospital Nacional de San Benito in El Peten, Guatemala, after the adoption of the laparoscopic approach. Laparoscopic cholecystectomies (LCs) between 2014 and 2015 (n = 42) were reviewed and matched by 58 randomly selected open cholecystectomies (OCs) during the same period. Patient demographics were similar in the LC and OC groups. Of the 63 patients who had elective surgery, 43 (68%) underwent OC. Conversion rate, hospital length of stay, and readmission rate were 4%, 4.8 days, and 5%, respectively. Complications were similar between groups. Despite the low number of LCs, their complications were not different from that of OCs. During the study period, a large number of cholecystectomies continued to be open, even in the elective setting. Published by Elsevier Inc.

    1988-08-01

    This study investigates how process heat from Guatemala's geothermal energy resources can be developed to reduce Guatemala's costly importation of oil, create new employment by encouraging new industry, and reduce fuel costs for existing industry. This investigation was funded by the US Agency for International Development and carried out jointly by the Guatemalan Government and the Los Alamos National Laboratory. Two sites, Amatitlan and Zunil, are being developed geothermally. Amatitlan is in the better industrial area but Zunil's geothermal development is more advanced. The industry around Zunil is almost exclusively agricultural and the development of an agricultural processing plant (freezing, dehydration, and cold storage) using geothermal heat is recommended. Similar developments throughout the volcanic zones of Guatemala are possible. Later, when the field at Amatitlan has been further developed, an industrial park can be planned. Potential Amatitlan applications are the final stage of salt refining, a thermal power plant, hospital/hotel heating and cooling, steam curing of concrete blocks, production of alcohol from sugar cane, and production of polyethylene from ethanol. Other special developments such as water pumping for the city of Guatemala and the use of moderate-temperature geothermal fluids for localized power production are also possible. 12 refs., 13 figs., 14 tabs.

    Introduction Campylobacteriosis is one of the leading causes of gastroenteritis worldwide. This study describes the epidemiology of laboratory-confirmed Campylobacter diarrheal infections in two facility-based surveillance sites in Guatemala. Methods Clinical, epidemiologic, and laboratory data were collected on patients presenting with acute diarrhea from select healthcare facilities in the departments of Santa Rosa and Quetzaltenango, Guatemala, from January 2008 through August 2012. Stool specimens were cultured for Campylobacter and antimicrobial susceptibility testing was performed on a subset of isolates. Multidrug resistance (MDR) was defined as resistance to ≥3 antimicrobial classes. Results Campylobacter was isolated from 306 (6.0%) of 5137 stool specimens collected. For children Guatemala; antimicrobial resistance was high, and treatment regimens in the ambulatory setting which included metronidazole and trimethoprim-sulfamethoxazole and lacked oral rehydration were sub-optimal.

Clinical, epidemiologic, and laboratory data were collected on patients presenting with acute diarrhea from select healthcare facilities in the departments of Santa Rosa and Quetzaltenango, Guatemala, from January 2008 through August 2012. Stool specimens were cultured for Campylobacter and antimicrobial susceptibility testing was performed on a subset of isolates. Multidrug resistance (MDR) was defined as resistance to ≥3 antimicrobial classes. Campylobacter was isolated from 306 (6.0%) of 5137 stool specimens collected. For children Guatemala; antimicrobial resistance was high, and treatment regimens in the ambulatory setting which included metronidazole and trimethoprim-sulfamethoxazole and lacked oral rehydration were sub-optimal.

    Electronic cigarettes (e-cigarettes) have the potential to normalize smoking and undermine tobacco control efforts. However, if well regulated, they also have a potential as smoking cessation aids. This study sought to determine the availability and types of e-cigarettes and e-liquids in Guatemala. We also assessed packaging characteristics and price. We surveyed a convenient sample of 39 Guatemala City retailers and purchased all e-cigarettes and e-liquids available. Duplicate samples (same brand, e-liquid type, flavor, nicotine content, or packaging) were purchased when prices were different between each other. Country of manufacture, flavor, expiration date, nicotine concentration, and price were recorded. We also documented package marketing strategies and warning labels. We purchased 64 e-cigarettes (53 unique and 11 duplicates) and 57 e-liquids (52 unique and 5 duplicates), mostly found on mall retailers. Most e-cigarettes (42, 66%) were first generation, followed by second (18, 28%) and third generations (4, 6%). Price of e-cigarettes differed significantly by generation. Most e-cigarettes (31, 58%) and 24 (46%) e-liquids did not include warning labels. Nicotine content was reported in 21 (39%) e-cigarettes that included e-liquids and 41 (79%) e-liquids' packages. E-cigarettes and e-liquids are available among a variety of retailers in Guatemala City and the industry is taking advantage of the fact that they are not regulated (eg, health claims, minimum sales age, and taxation). Our findings support the need for further research on e-cigarettes and e-liquids in Guatemala. To the best of our knowledge, this is the first study describing e-cigarettes and e-liquids available in retailers in a low/middle-income country like Guatemala. E-cigarettes and e-liquids were found in a variety of types, flavors, and nicotine concentrations in Guatemalan retailers. Our findings support the need for further research on e-cigarettes and e-liquids in Guatemala. © The Author

  1. Subduction of Proterozoic to Late Triassic continental basement in the Guatemala suture zone: A petrological and geochronological study of high-pressure metagranitoids from the Chuacús complex

    Many continental subduction complexes contain abundant granitic rocks coexisting with minor volumes of eclogite-facies rocks. Characterization of granitic protoliths is crucial to decipher the origin of subducted continental crust, whereas knowledge of its metamorphic evolution is required to constrain the mechanisms of burial and exhumation. In this work we present geochronological and petrological evidence that demonstrate the occurrence of a subducted Proterozoic to Late Triassic granitic basement in the Chuacús complex of central Guatemala. Metagranitoids exposed in this area are interlayered with eclogite and other high-pressure rocks, and their structure is considerably variable due to strain partitioning during deformation. Laser ablation-inductively coupled plasma-mass spectrometry U-Pb zircon data from two ferroan metagranites yield protolith crystallization ages of ca. 1.1 Ga and their trace-element abundances suggest an origin related to intraplate magmatism, while a high-silica, peraluminous metagranite is dated at 1.0 Ga and was probably originated by partial melting of a high-grade continental crust. On the other hand, two megacrystic to augen metagranitoids yield protolith crystallization ages of ca. 224 Ma, which are identical within errors to the protolith age of hosted eclogitic metabasites. Their high incompatible trace element abundances together with the observed spatial-temporal relationships with mafic protoliths suggest that Late Triassic bimodal magmatism in the Chuacús complex was probably originated in a within-plate setting. Regardless of their age or structure, the studied metagranites preserve evidences for high-pressure metamorphic equilibration, such as the occurrence of Ca-rich garnet (XCa up to 0.52) in association with phengite (Si contents of up to 3.4 pfu) and rutile. The integration of Zr-in-rutile thermometry and phengite barometry allows the peak metamorphic conditions to be constrained at 640-680 °C and 13 kbar. This

    Maternal and perinatal mortality continue to be a high priority problem on the health agendas of less developed countries. Despite the progress made in the last decade to quantify the magnitude of maternal mortality, few interventions have been implemented with the intent to measure impact directly on maternal or perinatal deaths. The success of interventions implemented in less developed countries to reduce mortality has been questioned, in terms of the tendency to maintain a clinical perspective with a focus on purely medical care separate from community-based approaches that take cultural and social aspects of maternal and perinatal deaths into account. Our innovative approach utilizes both the clinical and community perspectives; moreover, our study will report the weight that each of these components may have had on reducing perinatal mortality and increasing institution-based deliveries. A matched pair cluster-randomized trial will be conducted in clinics in four rural indigenous districts with the highest maternal mortality ratios in Guatemala. The individual clinic will serve as the unit of randomization, with 15 matched pairs of control and intervention clinics composing the final sample. Three interventions will be implemented in indigenous, rural and poor populations: a simulation training program for emergency obstetric and perinatal care, increased participation of the professional midwife in strengthening the link between traditional birth attendants (TBA) and the formal health care system, and a social marketing campaign to promote institution-based deliveries. No external intervention is planned for control clinics, although enhanced monitoring, surveillance and data collection will occur throughout the study in all clinics throughout the four districts. All obstetric events occurring in any of the participating health facilities and districts during the 18 months implementation period will be included in the analysis, controlling for the cluster

    A recent survey of public opinion has shown that 85 per cent of the public view their electric utility company favourably. This represents a 10 per cent increase over last year. A survey of 4,090 Canadians was conducted which looked at the perceptions of the value of electricity services compared to telephone, natural gas, banking, and home insurance services. The study showed that Canadian electric utility companies are viewed as positively as the telephone companies and almost as favourably as the banks. Some 71 per cent of respondents reported that the value they receive from their electric utility is excellent or good. Lower prices, better customer services and increased research into alternative power sources were among the benefits that Canadians perceive would result from a more competitive electricity sector. Some misgivings about deregulation included a belief that there would be less attention to environmental concerns and more outages. Four per cent of the respondents said they would 'definitely' switch to an alternative supplier of electricity, while 25 per cent said they would 'probably' switch to an alternative supplier of electricity. 2 tabs

    This report is a synthesis of the possibilities of CO{sub 2} storage in the Spanish subsurface. Compilation and analysis of geological information has been carried out, looking at surface and subsurface, in order to make a pre-selection of potential favourable units for CO{sub 2} storage, taking in account that each of this storages needs a confining formation to seal the storage. Before the storage selection, a general description of the great geological units of the Iberian Peninsula is done. Afterwards, borehole logging from petroleum exploration is analysed in these units, formations and areas of interest. The aim is to finally obtain a description of selected units and their possibilities of CO{sub 2} storage. (Author) 17 refs.

    2001-01-01

    At 3760 m, Agua volcano towers more than 3500 m above the Pacific coastal plain to the south and 2000 m above the Guatemalan highlands to the north. The volcano is within 5 to 10 kilometers (km) of Antigua, Guatemala and several other large towns situated on its northern apron. These towns have a combined population of nearly 100,000. It is within about 20 km of Escuintla (population, ca. 100,000) to the south. Though the volcano has not been active in historical time, or about the last 500 years, it has the potential to produce debris flows (watery flows of mud, rock, and debris—also known as lahars when they occur on a volcano) that could inundate these nearby populated areas.

    The purpose of this study was to (1) describe and compare two obstetric Mayan populations in Guatemala, the Tz'utujil and the Kachiquel and (2) evaluate possible associations of demographics, wood fuel use, and obesity with pregnancy/newborn outcomes. This cross-sectional study interviewed participants at the time of routine obstetric ultrasounds at three institutions in Santiago Atitlán and one institution in San Lucas Tolimán. Data were collected from January 2010 to May 2013. Data entry and statistical analysis were performed using EPI Info TM 7.1.2.0 (CDC). The two populations were similar in maternal age, BMI, ownership of a phone, gravidity (number of times a women has been pregnant), history of spontaneous abortions, history of term pregnancies, newborn birth weights, cesarean section rate, and percentage of low-birth-weight newborns (LBW Guatemala. The obstetric characteristics, differences, and similarities between these two Mayan populations should help in policy planning for obstetric care for these two populations and possibly other indigenous populations in Guatemala.

    A subgroup of tonsillar squamous cell carcinoma (SCC) is associated with human papillomavirus (HPV). Nevertheless, the prevalence of HPV seems to be variable in different regions and ethnic groups. There are no reports of HPV in tonsillar carcinomas in Guatemala, and data from Brazil are scarce. The aim of this study is to analyze and compare HPV presence in samples of tonsillar SCC from these countries. This study describes the histologic features, expression of p16 by immunohistochemistry (IHC), and HPV by in situ hybridization (ISH) in 13 Guatemalan and 13 Brazilian patients. All cases of tonsillar SCC from Guatemala were positive for p16, 92% expressed HPV by ISH, and 75% corresponded to the high-risk genotype 16/18. From the Brazilian patients, only four expressed p16, and all were negative for HPV. Cases from Guatemala, which were mostly nonkeratinizing SCC and originated from the crypt/reticular epithelium of the tonsil, had high-risk integrated HPV, whereas in Brazilian cases, which were mostly keratinizing SCC that originated from the surface epithelium, there was no association with HPV.

    Food marketing has been implicated as an important driver of obesity. However, few studies have examined food marketing in low- and middle-income countries (LMICs). This study documents the prevalence of advertising on cereal boxes in Guatemala and examines associations between various marketing strategies and nutritional quality. One box from all available cereals was purchased from a supermarket located in an urban area in Guatemala City, Guatemala. A content analysis was performed to document child-oriented marketing practices, product claims and health-evoking images. The Nutrient Profile Model (NPM) was used to calculate an overall nutrition score for each cereal (the higher the score, the lower the nutritional quality). In all, 106 cereals were purchased, and half of the cereals featured child-oriented marketing (54, 50.9%). Cereals had a mean (±s.d.) of 5.10±2.83 product claims per cereal, and most cereals (102, 96.2%) contained health-evoking images. Child-oriented cereals had, on average, higher NPM scores (13.0±0.55 versus 7.90±0.74, Ptargeting children were generally of poor nutritional quality. Cereals displaying health claims were also not healthier than those without such claims. Our findings support the need for regulations restricting the use of child-oriented marketing and health claims for certain products.

    This paper presents data from 2 recent maternal-child health (MCH) and family planning surveys in Guatemala and Panama and examines the extent to which the use of contraception is influenced by the use of MCH services as compared with the influence of an increase in parity. Fieldwork was initiated in July 1984 but not completed until April 1985. A total of 8240 women aged 15-49 years, of all marital statuses, completed interviews, representing 91% of households with eligible respondents. The findings suggest that utilization of MCH services and parity independently are associated with a woman's decision to use contraception. The study also found 2 groups that appear to be particularly in need of both MCH and family planning services: high parity women and Indians. Nonuse of MCH and family planning services may be due in part to their strong cultural beliefs. In both Guatemala and Panama, improved health care services for these 2 groups should be a priority. Contraceptive use in Panama was over twice as high as in Guatemala. However, method choice and residence-ethnicity patterns of use were similar in each country. In both countries and in all residence-ethnicity groups, female sterilization was the most prevalent method in use, followed by oral contraceptives, except for Panama rural Indians. In Panama, contraceptive use increases up to ages 30-34 and then declines, with a sharp decline for women 40-44. In Guatemala, contraceptive use is generally low for ages 15-24, then increases to a fairly constant level for ages 25-39.

    Associations between biological traits of animals and climate are well documented by physiological and local-scale studies. However, whether an ecophysiological phenomenon can affect large-scale biogeographical patterns of insects is largely unknown. Insects absorb energy from the sun to become mobile, and their colouration varies depending on the prevailing climate where they live. Here we show, using data of 473 European butterfly and dragonfly species, that dark-coloured insect species are favoured in cooler climates and light-coloured species in warmer climates. By comparing distribution maps of dragonflies from 1988 and 2006, we provide support for a mechanistic link between climate, functional traits and species that affects geographical distributions even at continental scales. Our results constitute a foundation for better forecasting the effect of climate change on many insect groups. PMID:24866819

    After a presentation of the elements to be taken into consideration when undertaking a comparative study of the diverse possible solutions for the future of a shut down nuclear reactor, this outlines the advantages of simultaneously decommissioning and conducting final shut down operations. It is clarified that in a real situation the benefits of demonstration and judgement on the technical solutions adopted are arguments in favour of this approach but that this is only true for the first case. The advantages of this approach in a systematic manner are then developed. In conclusion, the advantages associated with this approach are theoretically beyond question and it should not be rejected a priori. However, if it is a question of taken a decision on the future of a nuclear installation, it is necessary to quantify and compare the advantages and disadvantages of other approaches in order to make the best choice

    Full Text Available Southern Mexico and Central America have many water bodies of different morphology and water chemistry with an interesting zooplankton fauna, originating from North or South America. A set of 63 samples, taken in 2005 and 2008, from water bodies of the Yucatan Peninsula karst, Belize and Guatemala, were studied for the content of calanoid copepods. Old and recent literature was used to determine animals to species level. Drawings were prepared with a microscope and a camera lucida. A total of 32 samples with totally six species contained calanoid copepods: one estuarine pseudodiaptomid and five freshwater diaptomids. Pseudodiaptomus marshi was found at different salinities. It is confirmed that the commonest diaptomids in the Yucatan Peninsula are Arctodiaptomus dorsalis and Mastigodiaptomus nesus. The former was also recorded from Lake Amatitlan. Mastigodiaptomus nesus is as widespread as A. dorsalis but it is absent from the Lake Peten area in Guatemala. Mastigodiaptomus reidae was found in two shallow habitats, these specimens differ from those from the type locality by having a set of peculiar large spine-like processes on the last thoracic and the urosome segments of the females. Leptodiaptomus siciloides was found only in Lake Ayarza with high salinity. Prionodiaptomus colombiensis occurred in the highlands of Guatemala in Lago de Güija and in the Peten area in Laguna Sacpuy. We contributed with our occurrence records to a better knowledge of the geographic distribution of some calanoid copepods. Morphological findings in some species are of value for taxonomic differentiation between species.

    The shortage of trained health care personnel has been increasing worldwide. With the physician assistant (PA) profession, created in the United States in the 1960s, expanding globally, this study sought to ascertain whether PAs can be an innovative solution to this crisis. We conducted a convenience sample survey to assess the need for and acceptability of future PA professionals in Guatemala. Eighty-nine doctors, nurses, and community members from rural and urban areas of Guatemala participated in the survey. More urban (70%) than rural (58%) respondents found it difficult to access a doctor, with cost being the major reason (34%). Access in rural areas was reportedly limited by lack of doctors and inaccessible office hours. Most survey respondents considered PAs to be suitable and potentially helpful providers for Guatemala, with a preference for competencies in the diagnosis of serious illnesses, drug prescription, labor and delivery attendance, and care for injuries and fractures, especially in rural locations. Belonging to the community was deemed very important for a PA who would practice in the country.

    Noroviruses (NoVs) are a leading cause of acute gastroenteritis outbreaks and sporadic cases of diarrhea in industrialized countries. To study the prevalence and genetic diversity of NoVs in Guatemala, stool specimens were collected from hospitalized and ambulatory patients presenting with diarrhea (≥3 loose or liquid stools in a 24-hr period) who were enrolled in a prospective surveillance system in the Departments of Santa Rosa (October 2007 to August 2010) and Quetzaltenango (August 2009 to August 2010), Guatemala. Specimens were tested for rotavirus, enteric bacteria, and parasites by routine methods and for genogroups I and II NoV by real-time reverse transcription-PCR. A total of 2,403 stool specimens were collected from hospitalized (n = 528) and ambulatory patients (n = 1,875). Overall, 341 (14%) samples tested positive for NoVs including 114 (22%) hospitalized and 227 (12%) ambulatory patients. NoVs disease peaked during the winter (November-January) months. Among the 341 NoVs-positive patients, 32 (9%) were also positive for rotavirus, 32 (9%) for bacteria, and 9 (3%) for protozoa. Nucleotide sequences were obtained from 84 samples collected from hospitalized children aged Guatemala. The findings highlight the need to implement laboratory diagnostics for NoVs to improve appropriate clinical management of diarrheal diseases and guide vaccine development.

    Woodman, Neal

    2010-01-01

    The broad-clawed shrews (Soricomorpha: Soricidae: Cryptotis) encompass a clade of 5 species—Cryptotis alticolus (Merriam), C. goldmani (Merriam), C. goodwini Jackson, C. griseoventris Jackson, and C. peregrinus (Merriam)—that is known collectively as the Cryptotis goldmani group and is characterized by broadened forefeet, elongated and broadened fore claws, and broadened humeri. These shrews are distributed in highland regions from central Mexico to Honduras. Two broad-clawed shrews, C. goodwini and C. griseoventris, occur in southern Mexico and Guatemala and are presumed sister species whose primary distinguishing feature is the larger size of C. goodwini. In an investigation of variation within and between these 2 species, I studied characteristics of the postcranial skeleton. Statistical analyses of a variety of character suites indicate that the forelimb morphology in this group exhibits less intraspecific variation and greater interspecific variation than cranio-mandibular morphology, although most skull characters support groupings based on forelimb characters. Together, these characters define 4 distinct groups among the specimens examined. C. griseoventris is restricted to the northern highlands of Chiapas, Mexico, and C. goodwini occurs in the southern highlands of Chiapas and Guatemala. Herein, I describe 2 new species of broad-clawed shrews from the Sierra de los Cuchumatanes, Guatemala.

    To inform estimations of the potential impact of recently introduced pneumococcal conjugate vaccine (PCV), we report results of 11 years of pre-PCV surveillance for invasive pneumococcal disease (IPD) among children in Guatemala City. Cases of IPD in children younger than 5 years were identified by active surveillance at 3 referral hospitals in Guatemala City from October 1996 through 2007. Clinical and demographic data were obtained, and isolates of Streptococcus pneumoniae from normally sterile sites were serotyped using latex agglutination and confirmed by Quellung reaction. Four hundred fifty-two cases of IPD were identified with a case fatality rate of 21%. Meningitis was the most common cause of death (77% of all deaths) and occurred more often in infancy (median age 5 months) than other clinical syndromes. Of the 137 isolates serotyped, type 1 (26 cases, 17%), type 2 (25 cases, 16%) and type 5 (18 cases, 12%) were the most common. Serotype 2 was associated with a higher case fatality rate (28%), higher rate of meningitis (68%) and occurred in younger infants (median age, 3.5 months) than other common serotypes. Recently introduced PCV13 includes 73% of observed serotypes in the study. Infants with IPD presented at a young age. Serotype 2, rarely reported as a significant cause of IPD and not included in available PCVs, was a common cause of disease in this population. PCV13 introduction in Guatemala, begun in 2013, may not have as great an impact in disease reduction as has been observed in other countries.

    This contribution is based on a study dealing with the limitation or withdrawal of ownership rights to real estates in favour of the mining industry. All EU countries are included as of the year 2006. The interventions of the state concern ensuring entry to other people's lands to carry out exploration activities and restraining the proprietary rights of landowners in favour of mining, including expropriation. The countries where mining legislation does not cover state interventions are also presented.

  10. Natural selection can favour 'irrational' behaviour.

    Understanding decisions is the fundamental aim of the behavioural sciences. The theory of rational choice is based on axiomatic principles such as transitivity and independence of irrelevant alternatives (IIA). Empirical studies have demonstrated that the behaviour of humans and other animals often seems irrational; there can be a lack of transitivity in choice and seemingly irrelevant alternatives can alter decisions. These violations of transitivity and IIA undermine rational choice theory. However, we show that an individual that is maximizing its rate of food gain can exhibit failure of transitivity and IIA. We show that such violations can be caused because a current option may disappear in the near future or a better option may reappear soon. Current food options can be indicative of food availability in the near future, and this key feature can result in apparently irrational behaviour.

    Objective To document the prevalence of patients on hemodialysis in southwestern Guatemala who have chronic kidney disease (CKD) of non-traditional causes (CKDnt). Methods This cross-sectional descriptive study interviewed patients on hemodialysis at the Instituto Guatemalteco de Seguridad Social on their health and occupational history. Laboratory serum, urine and vital sign data at the initiation of hemodialysis were obtained from chart reviews. Patients were classified according to whether they had hypertension or obesity or neither. The proportion of patients with and without these traditional CKD risk factors was recorded and the association between demographic and occupational factors and a lack of traditional CKD risk factors analyzed using multivariate logistic regression. Results Of 242 total patients (including 171 non-diabetics) enrolled in hemodialysis in southwestern Guatemala, 45 (18.6% of total patients and 26.3% of non-diabetics) lacked traditional CKD risk factors. While agricultural work history was common, only travel time greater than 30 minutes and age less than 50 years old were significantly associated with CKD in the absence of traditional risk factors. Individuals without such risk factors lived throughout southwestern Guatemala's five departments. Conclusions The prevalence of CKDnT appears to be much lower in this sample of patients receiving hemodialysis in Southwestern Guatemala than in hospitalized patients in El Salvador. It has yet to be determined whether the prevalence is higher in the general population and in patients on peritoneal dialysis.

    For twenty years, the Regional Medfly Program in southern Mexico and Guatemala, central America - which is financed by Mexico, Guatemala and USA - has successfully halted the Medfly (Ceratitis capitata (Wied.)) dispersion toward Mexico and USA. After the pest eradication in Chiapas, Mexico, in 1982 and some vain efforts to contain it in Guatemala, a strategy has been formed in the construction of a static barrier of containment. However, this has been criticised frequently by the border society which has suffered for a long time because detection and control action sometimes result in big emergency plans as the answer to strong explosions and pest dispersions which have in turn occurred from climatic phenomena, such as El Nino, in 1998. The Medfly eradication in Guatemala has not been accomplished because the suppression technology used before sterile insect technique (SIT) had been based on malathion aerial bait spray. The aerial bait spray has been prohibited in Guatemala since 1987, following strong complaints from ecological groups and the beekeeping sector, as well as because of financial constraints. The xanthene dye technology that replaced the use of malathion has given new hopes and possibilities to the old project of pest eradication in Guatemala and Central America. However, moving the barrier from north to south and from east to west is necessary to prevent re-infestations in Mexico and pest-free areas in Guatemala. The development of new detection and control tools has also strongly supported the project, with the use of more efficient traps, such as the OBDT trap, baited with ammonium acetate, putrescine and trimethylamine (phase IV traps), trimedlure (TML)-laced yellow panel traps and TML-baited Jackson traps. The use of the improved chilled adult release system, the aerial bait sprays which are guided by the GPS and SATLOC navigation systems, the augmentative release of parasitoids and the artificial biological isolation of the infested areas all

    Background Elimination of onchocerciasis (river blindness) through mass administration of ivermectin in the six countries in Latin America where it is endemic is considered feasible due to the relatively small size and geographic isolation of endemic foci. We evaluated whether transmission of onchocerciasis has been interrupted in the endemic focus of Escuintla-Guatemala in Guatemala, based on World Health Organization criteria for the certification of elimination of onchocerciasis. Methodology/Principal Findings We conducted evaluations of ocular morbidity and past exposure to Onchocerca volvulus in the human population, while potential vectors (Simulium ochraceum) were captured and tested for O. volvulus DNA; all of the evaluations were carried out in potentially endemic communities (PEC; those with a history of actual or suspected transmission or those currently under semiannual mass treatment with ivermectin) within the focus. The prevalence of microfilariae in the anterior segment of the eye in 329 individuals (≥7 years old, resident in the PEC for at least 5 years) was 0% (one-sided 95% confidence interval [CI] 0–0.9%). The prevalence of antibodies to a recombinant O. volvulus antigen (Ov-16) in 6,432 school children (aged 6 to 12 years old) was 0% (one-sided 95% IC 0–0.05%). Out of a total of 14,099 S. ochraceum tested for O. volvulus DNA, none was positive (95% CI 0–0.01%). The seasonal transmission potential was, therefore, 0 infective stage larvae per person per season. Conclusions/Significance Based on these evaluations, transmission of onchocerciasis in the Escuintla-Guatemala focus has been successfully interrupted. Although this is the second onchocerciasis focus in Latin America to have demonstrated interruption of transmission, it is the first focus with a well-documented history of intense transmission to have eliminated O. volvulus.

    Guatemala's family planning association, the Asociacion Pro-Bienestar de la Familia (APROFAM) recently cut its ties with the nation's contraceptive social marketing program. The announced reasons for the disassociation was APROFAM's concerns about the legality of selling donated commodities. APROFAM helped create the program served as a member of the marketing program's board of directors, and was expected to function as the channel for the commidities donated by the US Agency for International Development (USAID). The marketing program will now be managed by the newly created Importadora de Farmaceuticos (IPROFA), a for-profit organization. This alters the legal status of the marketing program, and as a result, the program will be required to pay duties on USAID donated contraceptives. USAID cannot legally pay duties on its own contributions. Instead, the duies will be paid by IPROFA out of the revenues generated by the project. IPROFA will finance the 1st consignment of products with a bank loan, and the loan and duties on subsequent shipments will be paid out of the program's revenues. This strategy is not expected to pose legal problems for USAID, since the agency has no control over how programs use the revenues generated by selling the agency's commodities. As a result of the changed status, the marketing program must acquire it own storage and packaging facilities. According to Manuel DeLucca, the program's resident advisor, these problems will not delay the launch of the program's products scheduled for early 1985. The program plans to sell an oral contraceptive, a vaginal spermicidal tablet, and a condom. Orginal plans called for selling the low dose OC, Norminest; however, Norminest may not be approved for distribution in Guatemala, and USAID may replace Norminest with another product. As a result, the program may market Noriday, a normal dose pill instead of Norminest. Guatemalan registration of the spermicidal tablet the program is planning to sell is

    Overweight and obesity prevalence in children is now on the rise in low/middle-income countries, including Guatemala. Fast food consumption is a recognized contributing factor to this rise. Fast food restaurants use health claims, toy giveaways, price incentives and fast service to promote children's combo meals. This study sought to assess the use of toy giveaways, time to delivery and price incentives as marketing strategies in fast food chain restaurants in Guatemala. In addition, we sought to compare nutritional quality of combo meals with and without health claims. We visited one restaurant from each of the 8 major fast food chains in Guatemala and purchased all children's combo meals to assess the prevalence of toy giveaways, health claims, and difference in delivery time and price between the combo meal and each meal item purchased separately. Each item was then classified as "healthy" or "less healthy" using the UK Nutrition Profile Model. Nutrition information was collected on-site, from the restaurant website, or by calling the customer service phone number. We found 114 combo meals, 21 (18.4%) of which were children's combo meals. Five (24%) had nutrition information, all were classified by our analysis as "less healthy", and three had a health claim. On average, combo meals were US$1.93 less expensive than purchasing children's meal items individually ( p  = 0.01). Time to delivery was 1.44 min faster for combo meals compared to purchasing meal items individually ( p  = 0.19). Children's fast food combo meals in Guatemala were promoted using several marketing strategies that encourage consumption, including offering toy giveaways and price incentives. In addition, nutrition information is lacking in fast food chain restaurants. Public health advocates in Guatemala should consider a comprehensive approach to encourage healthier choices within fast food restaurants including policies that require fruit and vegetable options for meal side dishes

    2013-01-01

    Single-cigarette sales have been associated with increased cigarette accessibility to less educated, lower-income populations, and minors; lower immediate cost, and increased smoking cues. Since 1997, Guatemalan Law bans the sale of single cigarettes and packs with fewer than 20 cigarettes. In 2005, Guatemala ratified the World Health Organization Framework Convention on Tobacco Control (WHO FCTC); it is therefore obliged to "prohibit sale of cigarettes individually or in small packets." Blocks were numbered and randomly selected in Guatemala City and 3 neighboring towns. All stores in each block were surveyed. Single-cigarette and fewer than 20-cigarette pack sales were assessed by observation and purchase attempts. Cigarette brands and manufacturers (Philip Morris, PM or British American Tobacco, BAT) were also recorded. Percentages and means were used to describe data. Analyses were done using STATA 11.0. Of 398 stores and street vendors surveyed, 75.6% (301) sold cigarettes. Of these, 91% (275) sold single cigarettes and none sold fewer than 20-cigarette packs. Only informal economic sectors sold singles. There was no difference on sales between Guatemala City and neighboring towns and by store type. Buying 20 single cigarettes was US$ 0.83 more expensive than buying a 20-cigarette pack. The most prevalent brands were Rubios (PM), Marlboro (PM), Payasos (BAT), and After Hours (BAT). Single-cigarettes sales are highly prevalent among informal economic sectors in Guatemala City and its neighboring towns. Our data should prove useful to advocate for FCTC Article 16 enforcement in Guatemala.

    Guatemala, a party to the Framework Convention on Tobacco Control (FCTC), is obliged to promote the wider availability of smoking cessation treatment and to restrict tobacco advertising. Pharmacies are fundamental in providing smoking cessation medications but also might increase the availability of cigarettes. To assess availability of cessation medications and cigarettes and their corresponding advertising in Guatemala pharmacies. In Guatemala City a representative sample was selected from a list of registered pharmacies classified by type (non-profit, chain, independent). In addition, all pharmacies in the neighbouring town of Antigua were included for comparison. Trained surveyors used a checklist to characterise each pharmacy with respect to availability and advertising of cessation medications and cigarettes. A total of 505 pharmacies were evaluated. Cessation medications were available in 115 (22.8%), while cigarettes were available in 29 (5.7%) pharmacies. When available, medications were advertised in 1.7% (2) and cigarettes in 72.4% (21) of pharmacies. Chain pharmacies were significantly more likely to sell cessation medications and cigarettes, and to advertise cigarettes than were non-profit and independent pharmacies. Most pharmacies in Guatemala do not stock cessation medications or cigarettes. Cigarette advertising was more prevalent than advertising for cessation medications. FCTC provisions have not been implemented in Guatemala pharmacies.

    To report our experince in establishing a sustainable pediatric surgical outreach mission to an underserved population in Guatemala for treatment of strabismic disorders. A pediatric ophthalmic surgical outreach mission was established. Children were evaluated for surgical intervention by 3 pediatric ophthalmologists and 2 orthoptists. Surgical care was provided at the Moore Pediatric Surgery Center, Guatemala City, over 4 days. Postoperative care was facilitated by Guatemalan physicians during the second year. In year 1, patients 1-17 years of age were referred by local healthcare providers. In year 2, more than 60% of patients were prescreened by a local pediatric ophthalmologist. We screened 47% more patients in year 2 (132 vs 90). Diagnoses included congenital and acquired esotropia, consecutive and acquired exotropia, congenital nystagmus, Duane syndrome, Brown syndrome, cranial nerve palsy, dissociated vertical deviation, and oblique muscle dysfunction. Overall, 42% of the patients who were screened underwent surgery. We performed 21 more surgeries in our second year (58 vs 37), a 57% increase. There were no significant intra- or postoperative complications. Surgical outreach programs for children with strabismic disorders in the developing world can be established through international cooperation, a multidisciplinary team of healthcare providers, and medical equipment allocations. Coordinating care with local pediatric ophthalmologists and medical directors facilitates best practice management for sustainability.

    2011-03-01

    An incomplete skeleton recovered from a multiple, secondary burial at Tikal, Guatemala, shows malformed foot bones consistent with a diagnosis of bilateral idiopathic talipes equinovarus. Bones attributable to the skeleton include paired bowed fibulae, fragmentary calcanei, complete tali, naviculars, cuneiforms, metatarsals, and some phalanges. The tali are reduced in size, flattened, and hyperextended, with the tibia partially articulated on the calcaneus, posterior to the talus. The cuboid and cuneiforms show marked contraction of the inferior surfaces, and angulation. The metatarsals and phalanges present minor changes to the articulations, and slender shafts. Articulated, both feet show marked equinovarus deformity, with weight carried on the lateral margin and superior surface of the feet. Key conditions considered in the differential diagnosis are those producing an equinovarus or a calcaneocavovarus deformation, especially progressive neuromuscular disorders. This paper describes the nature of the bony changes, reconstructs the morphology of the feet, and offers a differential diagnosis. Scholars of the ancient Maya have identified artwork that appears to depict talipes equinovarus, although there was no osteological evidence for the condition among the Maya prior to the diagnosis of this case.

    Results of geological, volcanological, hydrogeochemical, and geophysical field studies conducted in 1988 and 1989 at the Tecuamburro geothermal site, Guatemala, indicate that there is a substantial shallow heat source beneath the area of youngest volcanism. Gases from acid-sulfate springs near Laguna Ixpaco consistently yield maximum estimated subsurface temperatures of 300??C. To obtain information on subsurface temperatures and temperature gradients, stratigraphy, fracturing, hydrothermal alteration, and hydrothermal fluids, a geothermal gradient core hole (TCB-1) was drilled to 808 m low on the northern flank of the Tecuamburro Volcano complex. The hole is located 300 m south of a 300m-diameter phreatic crater. Laguna Ixpaco, dated at 2910 years. TCB-1 temperature logs do not indicate isothermal conditions at depth and the calculated thermal gradient from 500-800 m is 230??C/km. Bottom hole temperature is close to 240??C. Calculated heat flow values are around 350-400 mW/m2. Fluid-inclusion and secondary-alteration studies indicate that veins and secondary minerals were formed at temperatures equal to or slightly less than present temperatures; thus, the Tecuamburro geothermal system may still be heating up. The integration of results from the TCB-1 gradient core hole with results from field studies provides strong evidence that the Tecuamburro area holds great promise for geothermal resource development. ?? 1992.

    Violence against women is prevalent around the world. In Guatemala it is pervasive. Living in a culture of violence oppresses women, children, the economy and society as a whole. It destroys families and can effect women emotionally and spiritually, as well as physically. Nurses have the power to intervene and influence change on a global level by taking action against abuse and oppression of women. By examining the pervasive nature of intimate partner violence and femicide in Guatemala, nurses can identify actions and interventions to combat violence on a global basis. © 2014 AWHONN.

    2000-08-01

    Certain glass nodules found at the archeological site at Tikal, Guatemala, have been considered as possible tektites. To test this possibility, magnetic studies have been made on three of the glass specimens. These specimens are similar to tektites, both visually and also because they contain very little Fe3+ as detected by Mössbauer spectroscopy. The magnetic Curie constants are similar in magnitude to those found for normal tektites but show some variation from point to point in the same specimen. This variation reflects an inhomogeneity in the iron concentration. The Fe2+ calculated from the Curie constants accounts for most of the iron. The temperature-independent component of the total dc magnetic susceptibility is several times higher than that found in tektites from other strewn fields. The high values can be explained if the glass contains metallic iron spherules with Fe in the parts per million range and/or a ferromagnetic component which does not saturate in a low magnetic field. The magnetic properties resemble those of Muong Nong type tektites and suggest that the Tikal glass specimens are tektites of the Muong Nong type.

    A portable, digital sensor network has been installed to closely monitor changing activity at Fuego volcano, which takes advantage of an international collaborative effort among Guatemala, U.S. and Canadian universities, and the Peace Corps. The goal of this effort is to improve the understanding shallow internal processes, and consequently to more effectively mitigate volcanic hazards. Fuego volcano has had more than 60 historical eruptions and nearly-continuous activity make it an ideal laboratory to study volcanic processes. Close monitoring is needed to identify base-line activity, and rapidly identify and disseminate changes in the activity which might threaten nearby communities. The sensor network is comprised of a miniature DOAS ultraviolet spectrometer fitted with a system for automated plume scans, a digital video camera, and two seismo-acoustic stations and portable dataloggers. These sensors are on loan from scientists who visited Fuego during short field seasons and donated use of their sensors to a resident Peace Corps Masters International student from Michigan Technological University for extended data collection. The sensor network is based around the local volcano observatory maintained by Instituto National de Sismologia, Vulcanologia, Metrologia e Hidrologia (INSIVUMEH). INSIVUMEH provides local support and historical knowledge of Fuego activity as well as a secure location for storage of scientific equipment, data processing, and charging of the batteries that power the sensors. The complete sensor network came online in mid-February 2007 and here we present preliminary results from concurrent gas, seismic, and acoustic monitoring of activity from Fuego volcano.

    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

    Estimate the burden of disease from Salmonella spp. and Shigella spp. in four departments of Guatemala in 2010. Burden of disease study based on document analysis of published population surveys, laboratory files, and surveillance data from the Health Management Information System (SIGSA) in four departments of Guatemala: Huehuetenango, Jutiapa, Quetzaltenango, and Santa Rosa, in 2010. Information was supplemented by a laboratory survey. Burden of disease was estimated using methodology adapted by the World Health Organization from the United States Centers for Disease Control and Prevention. Surveillance data yielded 72 salmonellosis and 172 shigellosis cases. According to population surveys, the percentage of the population that consults health services for diarrhea is 64.7% (95% CI: 60.6%-68.7%) in Quetzaltenango and 61.0% (95% CI: 56.0%-66.0%) in Santa Rosa. In the 115 laboratories that answered the survey (72.8% response rate), 6 051 suspected samples were collected for stool culture and 3 290 for hemoculture; 39.4% and 100.0% of them were processed, respectively. In all, 85 Salmonella spp. and 113 Shigella spp. strains were isolated. For each reported case of salmonellosis and shigellosis, it was estimated that 40 cases are not reported in Quetzaltenango, 55 in Huehuetenango, 345 in Santa Rosa, and 466 in Jutiapa. Estimated burden of disease ranged from 5 to 2 230 cases per 100 000 population for salmonellosis and from 60 to 1 195 cases per 100 000 population for shigellosis. Salmonellosis and shigellosis are a major public health problem in the departments studied and in Guatemala. Burden of disease from these pathogens is higher than that reported by SIGSA.

    For over ten years, the University of Bristol (U.K.) has run a field trip for masters students in Natural Hazards in the volcanically active areas of southern Guatemala, home to more than 13 million people. This trip has obvious benefits to its participants - it serves as an immersive and formative experience for students studying volcanic hazard, as well as a springboard for the work of the researchers who lead it. Over the years, it has helped to build strong collaborative ties between academic researchers at Bristol and Guatemala's geologic survey (INSIVUMEH) and emergency management agency (CONRED), facilitating the sharing of data, expertise, and monitoring equipment. The students' regular presence has also enabled infrastructure improvements at Fuego Volcano Observatory, which is itself hosted and partly staffed by the residents of Panimache, a small village just a few miles from the volcano's summit. This field trip does raise challenges, however - an influx of foreign students can draw questions from community members for whom the benefits are indirect (i.e., local job creation or infrastructure improvement) or intangible (i.e., incremental contributions to the body of knowledge regarding volcanic hazard). In this presentation, we'll share stories of our experiences of effective community collaboration in Guatemala. In the spirit of discussion, we would also like to explore the opportunities that exist to better utilise this trip, along with the energy and expertise of its participants, to maximise the positive impact on (and resilience of) local communities, particularly those in the small and largely indigenous villages that populate Fuego Volcano's flanks.

    Childhood overweight in Guatemala is now becoming a public health concern. Child-oriented marketing contributes to increase children's food preference, purchase and consumption. This study sought to assess the availability of child-oriented snack foods sold in school kiosks and convenience stores near public schools in Guatemala, to identify the marketing techniques used in child-oriented snack food packages and to classify the snacks as "healthy" or "less-healthy". We purchased all child-oriented snacks found in stores inside and within 200 square meters from four schools in an urban community. Snacks were classified as child-oriented if the package had any promotional characters, premium offers, children's television/movie tie-ins, sports references, or the word "child". We used a checklist to assess child-oriented references and price. Snacks were classified as "healthy" or "less-healthy" according to the UK standards for the Nutritional Profiling Model. We analyzed 106 packages found in 55 stores. The most commonly used technique was promotional characters (92.5%) of which 32.7% were brand-specific characters. Premium offers were found in 34% of packages and were mostly collectibles (50%). Most marketing techniques were located on the front and covered nearly 25% of the package surface. Median (interquartile range) price was US$ 0.19 (0.25). Nutrition labels were found in 91 (86%) packages and 41% had a nutrition related health claim. Most snacks (97.1%) were classified as "less-healthy". In Guatemala, the food industry targets children through several marketing techniques promoting inexpensive and unhealthy snacks in the school environment. Evidence-based policies restricting the use of promotional characters in unhealthy snack food packages need to be explored as a contributing strategy to control the obesity epidemic.

    Worldwide, seasonal influenza causes about 500,000 deaths and 5 million severe illnesses per year. The environmental drivers of influenza transmission are poorly understood especially in the tropics. We aimed to identify meteorological factors for influenza transmission in tropical Central America. We gathered laboratory-confirmed influenza case-counts by week from Guatemala City, San Salvador Department (El Salvador) and Panama Province from 2006 to 2010. The average total cases per year were: 390 (Guatemala), 99 (San Salvador) and 129 (Panama). Meteorological factors including daily air temperature, rainfall, relative and absolute humidity (RH, AH) were obtained from ground stations, NASA satellites and land models. For these factors, we computed weekly averages and their deviation from the 5-yr means. We assessed the relationship between the number of influenza case-counts and the meteorological factors, including effects lagged by 1 to 4 weeks, using Poisson regression for each site. Our results showed influenza in San Salvador would increase by 1 case within a week of every 1 day with RH>75% (Relative Risk (RR)= 1.32, p=.001) and every 1C increase in minimum temperature (RR=1.29, p=.007) but it would decrease by 1 case for every 1mm-above mean weekly rainfall (RR=0.93,pGuatemala had 1 case increase for every 1C increase in minimum temperature in the previous week (RR=1.21, p<.001), and for every 1mm/day-above normal increase of rainfall rate (RR=1.03, p=.03) (model pseudo-R2=0.54). Our findings that cases increase with temperature and humidity differ from some temperate-zone studies. But they indicate that climate parameters such as humidity and temperature could be predictive of influenza activity and should be incorporated into country-specific influenza transmission models

    As the first large subduction thrust earthquake off the coast of western Guatemala in the past several decades, the 07 November 2012 Mw=7.4 earthquake offers the first opportunity for a geodetic study of coseismic and postseismic behavior for a segment of the Middle America trench where frictional coupling makes a transition from weak coupling off the coast of El Salvador to strong coupling in southern Mexico. We use measurements at 19 continuous GPS sites in Guatemala, El Salvador, and Mexico to estimate the coseismic slip and post-seismic deformation of the November 2012 Champerico (Guatemala) earthquake. Coseismic offsets range from ~47 mm near the epicenter to El Salvador. An inversion of the geodetic data indicate that that up to ~2 m of coseismic slip occurred on a ~30 km by 30 km rupture area between ~10 and 30 km depth, encouragingly close to the global CMT epicenter. The geodetic moment of 13 x 1019 N·m and corresponding magnitude of 7.4 both agree well with independent seismological estimates. An inversion for the postseismic fault afterslip shows that the transient postseismic motions recorded at 11 GPS sites are well fit with a logarithmically decaying function. More than 70 per cent of the postseismic slip occurred at the same depth or directly downdip from the main shock epicenter. At the upper limit, afterslip that occurred within 6 months of the earthquake released energy equivalent to only ~20 per cent of the coseismic moment. The seismologically derived slip solution from Ye et al. (2012), which features more highly concentrated slip than our own, fits our GPS offsets reasonably well provided that we translate their slip centroid ~51 km to the west to a position close to our own slip centroid. The geodetic and seismologic slip solutions thus suggest bounds of 2-5 m for the peak slip along a region of the interface no larger than 30 x 30 km and possibly much smaller.

Para ello se revisa rápidamente el contexto general del inicio de la producción de café en el país, las características de la región estudiada y el recorrido realizado a las fincas cafetaleras mencionadas. Además, con el análisis de la legislación nacional guatemalteca sobre el tema de patrimonio cultural, se logra evidenciar el valor patrimonial cultural de las fincas cafetaleras para Guatemala, su estado actual de conservación y la necesidad de revitalización en función del desarrollo sostenible del área de estudio y del país. The importance of the existence of coffee plantation estates (architectural complexes located in the southwest region of Guatemala, known as “Costa Cuca” and the qualities and values they possess, should be considered as cultural heritage. This importance is demonstrated by the analysis of the two case studies presented in this article. To accomplish this purpose and to successfully argue that these complexes should be elevated to cultural heritage of our country, maintain their current condition of conservation and, in fact, be preserved and revitalized, the analysis includes a quick revision of the general context of the production of coffee in its early years, facts about the characteristics of the proposed region, the results of visits to these complexes and a profound revision of the current legislation in terms of cultural heritage in our country.

    We estimated the prevalence and severity of asthma, and the association with cooking on open wood fires, as preparation for a large-scale randomized field trial on effects of indoor air pollution and child health. This is one of the first systematic studies of asthma and indoor wood-smoke pollution and to our knowledge the first asthma study in a purely indigeneous population in Latin America. The mothers of 1058 children aged 4-6 years were interviewed, using the standardized ISAAC (International Study of Asthma and Allergies in Childhood) procedures and questionnaire. The study population is a Mam-speaking (Maya), indigenous group living at relatively high altitude (2000 m) in Western Guatemalan Highlands. We found that asthma prevalence is low among indigenous children in Guatemala, compared to other populations in Latin America. Only 3.3% of the children reported wheezing symptoms in the last 12 months, and 72% wheezing symptoms ever. The majority of the current wheezers had at least one of the criteria for severe asthma. The prevalence of all the symptoms of asthma was higher in children from households that used open fires compared to improved stoves with chimneys. In a logistic regression model, use of open fire for cooking was a significant risk factor for a number of asthma symptoms, with odds ratios varying from 2.0 to 3.5. Among the different cooking technologies (1-improved stove with chimney, 2-mixture of gas and open fire, 3-open fire) trends of higher prevalence with more pollution was found for some of the symptoms. Hence use of open fire for cooking, may be an important risk factor for asthma symptoms and severity.

    Social participation has been recognized as an important public health policy since the declaration of Alma-Ata presented it as one of the pillars of primary health care in 1978. Since then, there have been many adaptations to the original policy but participation in health is still seen as a means to make the health system more responsive to local health needs and as a way to bring the health sector and the community closer together. To explore the role that social participation has in a municipal-level health system in Guatemala in order to inform future policies and programs. Documentary analysis was used to study the context of participation in Guatemala. To do this, written records and accounts of Guatemalan history during the 20th century were reviewed. The fieldwork was carried out over 8 months and three field visits were conducted between early January of 2009 and late March of 2010. A total of 38 in-depth interviews with regional health authorities, district health authorities, community representatives, and community health workers (CHWs) were conducted. Data were analyzed using thematic analysis. Guatemala's armed civil struggle was framed in the cold war and the fight against communism. Locally, the war was fed by the growing social, political, and ethnic inequalities that existed in the country. The process of reconstructing the country's social fabric started with the signing of the peace agreements of 1996, and continued with the passing of the 2002 legal framework designed to promote decentralization through social participation.

    Immunization coverage levels in Guatemala have increased over the last two decades, but national targets of ≥95% have yet to be reached. To determine factors related to undervaccination, Guatemala's National Immunization Program conducted a user-satisfaction survey of parents and guardians of children aged 0-5 years. Variables evaluated included parental immunization attitudes, preferences, and practices; the impact of immunization campaigns and marketing strategies; and factors inhibiting immunization. Based on administrative coverage levels and socio-demographic indicators in Guatemala's 22 geographical departments, five were designated as low-coverage and five as high-coverage areas. Overall, 1194 parents and guardians of children aged 0-5 years were interviewed in these 10 departments. We compared indicators between low- and high-coverage areas and identified risk factors associated with undervaccination. Of the 1593 children studied, 29 (1.8%) were determined to be unvaccinated, 458 (28.8%) undervaccinated, and 1106 (69.4%) fully vaccinated. In low-coverage areas, children of less educated (no education: RR=1.49, p=0.01; primary or less: 1.39, p=0.009), older (aged>39 years: RR=1.31, p=0.05), and single (RR=1.32, p=0.03) parents were more likely to have incomplete vaccination schedules. Similarly, factors associated with undervaccination in high-coverage areas included the caregiver's lack of education (none: RR=1.72, p=0.0007; primary or less: RR=1.30, p=0.05) and single marital status (RR=1.36, p=0.03), as well as the child's birth order (second: RR=1.68, p=0.003). Although users generally approved of immunization services, problems in service quality were identified. According to participants, topics such as the risk of adverse events (47.4%) and next vaccination appointments (32.3%) were inconsistently communicated to parents. Additionally, 179 (15.0%) participants reported the inability to vaccinate their child on at least one occasion. Compared to high

    Imported malaria threatens control and elimination efforts in countries that have low rates of transmission. In 2010, an outbreak of Plasmodium falciparum malaria was reported among United Nations peacekeeping soldiers from Guatemala who had recently returned from the Democratic Republic of the Congo (DRC). Epidemiologic evidence suggested that the soldiers were infected in the DRC, but local transmission could not be ruled out in all cases. We used population genetic analyses of neutral microsatellites to determine the outbreak source. Genetic relatedness was compared among parasites found in samples from the soldiers and parasite populations collected in the DRC and Guatemala; parasites identified in the soldiers were more closely related to those from the DRC. A phylogenetic clustering analysis confirms this identification with >99.9% confidence. Thus, results support the hypothesis that the soldiers likely imported malaria from the DRC. This study demonstrates the utility of molecular genotyping in outbreak investigations.

    This paper presents one of the first large-scale collaborative research projects in ethnopharmacology, to bring together indigenous stakeholders and scientists both in project design and execution. This approach has often been recommended but rarely put into practice. The study was carried out in two key indigenous areas of Guatemala, for which very little ethnopharmacological fieldwork has been published. To document and characterize the ethno-pharmacopoeias of the Kaqchikel (highlands) and Q'eqchi' (lowlands) Maya in a transdisciplinary collaboration with the two groups Councils of Elders. The project is embedded in a larger collaboration with five Councils of Elders representing important indigenous groups in Guatemala, two of which participated in this study. These suggested healing experts reputed for their phytotherapeutic knowledge and skills. Ethnobotanical fieldwork was carried out over 20 months, accompanied by a joint steering process and validation workshops. The field data were complemented by literature research and were aggregated using a modified version of the International Classification of Diseases (ICD-10) and Trotter & Logan's consensus index. Similar numbers of species were collected in the two areas, with a combined total of 530 species. This total does not represent all of the species used for medicinal purposes. Remedies for the digestive system, the central nervous system & behavioral syndromes, and general tissue problems & infections were most frequent in both areas. Furthermore, remedies for the blood, immune & endocrine system are frequent in the Kaqchikel area, and remedies for the reproductive system are frequent in the Q'eqchi' area. Consensus factors are however low. The Kaqchikel, in contrast to the Q'eqchi', report more remedies for non-communicable illnesses. They also rely heavily on introduced species. The transdisciplinary research design facilitated scientifically rigorous and societally relevant large-scale fieldwork, which

  20. Can corruption favour growth via the composition of government spending?

    In an endogenous growth model with two public goods, we analytically derive the optimal composition of government spending in the presence of corruption. Although corruption results in a loss of productivity per se, an increase in corruption in the category of public spending that is harmed relatively more by corruption could have a favourable effect on growth, as it would encourage a benevolent government to divert spending towards the public good that is more productive, net of corruption.

    Singapore's fairly small size belies its wealth which comes not from production and use of its own raw materials including mineral products, but from importing raw materials and using them in manufacturing and refining. The state has a granite core exposed in the center of the island covered on the west by quartzites and shales, and on the east by recent detritus. There is no mining industry and no uranium potential is assigned to Singapore. (author)

    The Italian Republic comprises a 1200 - Km - long peninsula ex- tending from southern Europe into the Mediterranean Sea, and a number of adjacent islands, among which the principals are Sicily and Sardinia. The total area is in excess of 300,000 Sq.Km, the islands account for some 50, 000 Sq.Km. From a physiographic and morphologic point of view, Italy mainly consists of the Alpine region and the Po valley to the North and of the Appennine range and small Coastal plains to the Centre and South. Plains occupied only 20% of the total area, hills and mountains, up to 4,810 m of elevation, contribute almost equally to the remaining 80%. The most promising uranium mineralizations have been found in the Bergamasc Alps, near the small town of Novazza. Pitchblende and minor sphalerite (formation temperature, 80 deg. - 100 deg. C) occur disseminated in volcanics of permian age. The host rocks at the Novazza uranium deposit, consist of an acid ignimbrite with cineritic texture. The rocks have been affected by metasomatism which brought abundant neo-formation minerals such as silica, sericite, carbonates and minor adularia, albite and muscovite. The reasonably assured resources of the Novazza deposit have been estimated to be 1,200 ton of U having a grade of 900 p.p.m. U. Estimated additional resources are 1,000 ton U. Production is scheduled to start in 1980

    1976-12-01

    Although Afghanistan has an extent of some 650,065 square kilometres, only a very small proportion of it has been surveyed for uranium, and that only at the preliminary reconnaissance stage. Earlier work by bi-lateral teams identified a number of small uranium anomalies and occurrences and more recently (1974-75) an IAEA geologist discovered evidence of uranium mineralisation in the Neogene - Lower Pleistocene continental sediments of the Jalalabad Basin to the east of Kabul. The I.A.E.A. expert outlined three areas totalling 20,000 km where systematic uranium exploration would be justified. Up to the present no positive programme has been agreed. On very tenuous evidence a Speculative Potential of 2000 tonnes U 3 O 8 is suggested for Afghanistan. (author)

    Greece, with an area of 131,944 km 2 , has been actively explored since 1971 under a programme of co-operation with UNDP and IAEA on which close to US $1 million have been spent so far. The programme is focused on the Rhodope Precambrian massif, which is the most attractive structural unit from the geological point of view. The indications available at present, and which have been known for a long time, are also to be found in this unit. They are associated either with Tertiary continental volcanism or with detritic sediments in basins covering this massif. So far there is no evidence of their being of any economic value. The paucity of data available on the basement of the Rhodope precludes any prediction as to the possibility of its containing Pre-cambrian uranium mineralizations. One might perhaps think in terms of mineralizations of the alaskite or alkaline complex type, or also of vein-type deposits. But it is primarily in the deposits associated with tertiary trachy-rhyolitic volcanism that we have most confidence, especially in the Rhodope massif and the Vardar region but possibly elsewhere in the Hellenides as well. All things considered, we place Greece in Group 2 of the IUREP classification. (author)

    Finland covers an area of 337,000 skm. One third of the country lies north of the northern polar circle. 31,613 skm are covered by lakes. 71% of the landscape are covered by coniferous -wood. Climatlcal conditions are continental. The topography of the country is gently rolling with highest elevations of 300 m in the northern part. The most interesting geological units for uranium are Karelian, marginal meta-sediments, mainly quarzites and conglomerates but also schists. These schists are intruded by orogenlc plutonic rocks which are 1800-My-old. Potassium granites are common adjacent to the contact of the Pre-karelian basement (2500 My). In addition to these geological environment uranium and thorium minerals have been found in a large carbonatite in northern Finland, which is explored now

    Uranium occurrences and resources - To date the uranium identified in Belgium is limited to a number of occurrences and none of these have as yet proved significant from a reserve or resource viewpoint. The main uranium occurrences ares (1) In the Upper Cambrian graphite schists corresponding to the culm of Sweden small zones are found (30 - 50 cm thick) with an average of 20 ppm uranium. (2) Near Vise at the base of the Carboniferous the Visean formation is discordantly superimposed on the Permian (Frasnian) and overlain by shales and phyllites. Solution pockets at the boundary contain phosphatic lenses that contain uranium values of up to 200 ppm. Autunite and Torbernite are the main uranium minerals associated with a number of complex phosphatic minerals. Within the Chalk (Maestrichtien) of the Mons basin, that is mainly in the Ciply - St. Symphorien and Baudow district. Here is found enrichment of uranium up to 140 ppm over large areas related to phosphatic chalk. The thickness of the zone varies from a few to 20 metres. However, as the P 2 O 5 content is not high enough for the deposits to be exploited at present for phosphate there is little possibility of the uranium being concentrated at high enough levels to be exploited for itself alone. (4) Near to Vielsalm (in the Stavelot Massif) are some thin quartz veins containing small amounts of copper and uranium minerals (Torbornite). Values of up to 70 ppm are recorded. (5) A number of low uranium values are recorded associated with phosphatic nodules and zones in the Lower Pleistocene and Tertiary

    Sikkim is a country in the eastern Himalayas and is bound on the west by Nepal, on the north by Tibet, on the east by Bhutan and on the south by India. Precambrian Darjeeling gneiss forms the rim of the amphitheatre while schists of Late Precambrian to Lower Paleozoic rocks form tee habital interior. A small outcrop of carboniferous to Permain methomorphic rocks is preserved in the Tista Basin as well in a thin outcrop trust upon fluvitile beds of Sivalik which is mostly of Pliestocene age. Imbricate thrusts have stacked the rocks in a vast heap where reverse metamorphism is common. Ni information is available concerning uranium occurrences and resources as well as past and present explorations. The uranium potential of Sikkim is almost zero

    Brunei is a very small country consisting of only 5,800 sq km, and with only 150,000 people. Its main mineral products are crude oil and natural gas. It is hot and humid throughout the year being located only 4 degrees north of the equator on the island of Borneo. The sultanate of Brunei contains very thick sediments, some of which probably have the characteristics of a good uranium host rock for sandstone type deposits, but tacking a classic source, the uranium potential is minimal. Potential for other types of uranium deposits is likewise considered minimal. Therefore Brunei is assigned a potential in category 1 (less than 1000 tonnes U). (author)

    1977-11-01

    The Chaine Annamatique represents the last of the three orogenic episodes that shook Indochina and forms most of Vietnam's boundary with Laos, In south Vietnam the mountains which have a north-south trend are formed of granites, gneisses and mica schists and are inseparable from the anti-hercynian formations. Iron ore, gold, lead, copper, tin, wolfraun, bismuth and molybdenium minerals are found. Plans had been made in 1960 to prospect for uranium but no information is available on whether that work was ever done. The only evidence of occurrences of nuclear raw materials is that titaniferous sands occur in several coastal regions and that uranium was once listed as having been produced in Forth Vietnam. Although the geology of Vietnam is not very conducive to the formation and preservation of uranium deposits it is possible that because of the granite terrain and presence of other metalliferous minerals, the Speculative Potential should be stated as in category 2 i.e. from 1,000 to 10,000 tonnes uranium.

    International Nuclear Information System (INIS)

    1977-08-01

    Chile has an area of 740,760 square kilometers. The capital is Santiago. The country is 4,183 km. long and ranges from 22.5 to about 354 km. in width. Its chief topographic features para]lei each other - the Coastal Range, Andes Mountains and Central Valley. The Coastal Range rises to 2,130 meters in the north, but averages from 610 to 700 meters high generally. The range plunges into the Pacific Ocean far south of Valparaiso and reappears in the southern archipelagic islands. The Andes extend along nearly the entire length of Chile and contain 100 volcanoes. Andean peaks range mostly from 3,000 to 6,700 meters in elevation. In southern Chile the Andes are lower, and contain about a dozen major lakes. The mountains disappear in Chilean Patagonia, but reappear at Cape Horn. The Central Valley lies between the Coastal Range and the Andes, being best defined in the midland region as a 64 to 72 km sloping plain. It is the Chilean heartland with three-quarters of the country's population. Salt basins are found over much of northern Chile in the very arid desert, while the region south of the Gulf of Reloncavi consists of unpopulated islands, fjords, channels and heavily forested mountains. The Strait of Magellan, the Tierra del Fuego archipelago and a flat grassland area make up the extreme southern end of the country. Much of Chile is subject to flash floods, earthquakes, volcanic eruptions, landslides and avalanches. In September 1976 the Comision Chilena de Energia Nuclear (CCEN) was given exclusive rights to negotiate contracts with private companies for the exploration, development and mining of uranium and other radioactive minerals. The new law provides the CCEN with considerable flexibility in the terms of the contracts. Pre-964 owners of uranium deposits may reach agreements with foreign companies to mine the uranium, but since 1964 all uranium has belonged to the state. Uranium produced in the country can only be exported after Chile's needs have been met. The CCEN has invited proposals from international mining companies for the recovery of uranium from copper-bearing waters at the large Chuquicamata mine. As of mid-1977, it was reported that one proposal from all. S. company had been received. It has been estimated that production of 85 tonnes U/year might be realized here. Relatively little interest is shown in uranium by domestic (Chilean) companies because of the fear that the discovery of uranium might lead to nationalization of the properties. In spite of the possibilities mentioned above, there has been relatively little uranium discovered to date in Chile. In view of the relatively small size of these known deposits and until reconnaissance has taken a harder look at these possibilities, it would be prudent to place the potential of Chile in the 1,000-10,000 tonnes range

    In Australia most exploration for uranium has been conducted by companies and individuals. The geological mapping and airborne radiometric surveying conducted by the BMR is made available to interested persons. Exploration for uranium in Australia can be divided into two periods - 1947 to 1961 and 1966-1977. During the first period the Commonwealth Government introduced measures to encourage uranium exploration including a system of rewards for the discovery of uranium ore. This reward system resulted in extensive activity by prospectors particularly in the known mineral fields. Equipped with a Geiger counter or scintillometer, individuals with little or no experience in prospecting could compete with experienced prospectors and geologists. During this period several relative small uranium deposits were discovered generally by prospectors who found outcropping mineralisation. The second phase of uranium exploration in Australia began in 1966 at which time reserves amounted to only 6,200 tonnes of uranium and by 3 977 reserves had been increased to 289,000 tonnes. Most of the exploration was done by companies with substantial exploration budgets utilising more advanced geological and geophysical techniques. In the field of airborne radiometer the development of multi-channel gamma ray spectrometers with large volume crystal detectors increased the sensitivity of the tool as a uranium detector and resulted in several major discoveries. Expenditure or exploration for uranium increased from 1966 to 1971 but has declines in recent years. After listing the major geological elements of Australia, its uranium production and resources are discussed. During the period 1954-71 the total production of uranium concentrate in Australia amounted to 7,780 tonnes of uranium, and was derived from deposits at Rum Jungle (2,990 tonnes U) and the South Alligator River (610 tonnes U) in the Northern Territory, Mary Kathleen (3,460 tonnes U) in Queensland and Radium Hill (720 tonnes U) in South Australia. The only production at the present time is from the Mary Kathleen deposit which as at 30 June 1977 had produced a further 513 tonnes of uranium since it recommenced operations in 1976. Australia's uranium resources as at 30 June 1977 are estimated as follows (1) Recoverable up to a cost of US$80/kg U (US$30/lb U 3 O 8 ): Reasonably assured resources: 289-000 tonnes U; Estimated additional resources: 44,000 tonnes U. (2) Recoverable at a cost of US$80-130/kg U (US$30-50/lb U 3 O 8 ): Reasonably assured resources : 7,000 tonnes U; Estimated additional resources : 5,000 tonnes U. The reasonably assured resource category is as defined by NEA/IAEA. In expressing Australia's resources the estimated additional resource category is defined as: 'Estimated Additional Resources are confined to uranium which could be recovered within the given cost ranges from those known deposits where there are insufficient data to classify the resources as 'Reasonably Assured', and to extensions of known deposits beyond the limits of 'Reasonably Assured Resources' in those deposits. Quantitative estimates of speculative uranium resources have not been made for Australia

    Bolivia has an area of 1,098,580 square kilometers. Its capital is La Paz. The western part of the country is dominated by two ranges of the Andes Mountains, the Cordillera Occidental on the vest flank of the high plateau (Altiplano) and the Cordillera Real (or Oriental) on the east flank. The northern Andes average 5,486 meters in elevation; the southern Andes are not as lofty. The Altiplano is 3,658 to A,267 meters high and 129 km. in average width; it is the largest basin of inland drainage in South America and contains the renowned Lake Titicaca on the Peruvian-Bolivian border. The eastern tropical lowlands or pampas (Oriente) comprise about two-thirds of the country, with rain forest in the northern portion. An intermediate zone of valleys and basins lies between the eastern Andes and Oriente. Bolivia differs from other Andean countries, like Chile, Peru and Ecuador, in having large areas of Preeambrian schists, gneisses, migmatites and granites. These crop out in the eastern part of the country. Parts of these rocks contain banded iron formations (i.e., in the Muttin region) and are probably early Precambrian in age. Little systematic exploration for uranium was undertaken in Bolivia until the late 1960's. In 1967, 1968 and 1969 technical assistance was requested from, and provided by, the IAEA. This work led to evaluation of radioactive anomalies in veins of northeast Bolivia and in sandstones in the extreme southern part of the country. Although no uranium reserves are now credited to Bolivia, the geologic possibilities for several kinds of uranium deposits coupled with the relatively limited work done to date suggest that uranium orebodies will be discovered. It is estimated that the potential resources of Bolivia are in the range of 10,000 to 100,000 tonnes uranium

    Malaysia is a country of 330,000 square kilometers and a population of 11.9 million. The country is divided into two parts 640 kilometers apart. West Malaysia consists of the Malay Peninsula, and East Malaysia of the provinces of Sarawak and Sabah, formerly North Borneo. The country is the world's leading producer of tin and rubber. Geologic descriptions in detail are difficult to find although maps are available. Uranium exploration, chiefly by the Malaysian Geological Survey, has been carried out without discovery of commercial quantities. Based on possible recovery of uranium from deeply weathered granites on the Malay Peninsula, and possible discoveries in East Malaysia, a uranium potential of 1,000 to 10,000 tonnes U (category 2) is assigned.

    Turkey has an area of 296 185 sq mi or 767 120 square kilometers. The geology is dominated lay Tertiary and post-Tertiary rocks which are very widespread but extensive outcrops of Mesozoic rocks also occur. Paleozoic rocks, mainly gneisses, mica schists and quartzites occur in the ancient massifs, principally the Istranca massif in Thrace, the Merideres massif in western Anatolia and the Karrshir massif in central Anatolia. Prospecting for uranium began in Turkey in 1953 and the Atomic Energy Raw Materials Division of the Maden Tetkikive Arama Enstitusu (M.T.A.) was founded in 1956. By 1962 a total of 78% of the whole country had been covered by serial radiometric reconnaissance prospecting. Uranium was discovered at Kasar in western Anatolia in 1961 and several hundred tons of reserves estimated two years later. Uranium prospecting was largely recessed from 1963 to 1967. IAEA/UNDP assistance was provided in 1962-63 and 1965 and between 1974 and 1977 in a detailed exploration programme in the Kasar area. In the whole country nearly 600 anomalies and occurrences had been identified by 1963. Several occurrences principally in Western Anatolia had been assigned a small reserve. A recent official estimate places the total national reserve at 3150 tonnes uranium in the less than 30% category of reasonably assured resources. A speculative Potential of between 30,000 and 50,000 tonnes uranium is considered to be reasonable. (author)

    Jordanian geology is dominated by the Great Rift Valley System. Most of the country is covered by Cretaceous and Eocene sediments, largely sandstones and limestones. These include phosphorates and bituminous limestones in the Upper Cretaceous, South of the Dead Sea, Mesozoic and Paleozoic rocks overlie exposed granitic Pre Cambrian basement rocks carrying many minor intrusives . Phosphates provide the main mineral export of Jordan. The Natural Resources Authority (Geological Survey and Bureau of Mines) initiated a survey in 1972 of the distribution of uranium on the phosphorite horizon. In 1974 the Survey calculated that the uranium content of the phosphate areas surveyed up to that time was 5 million metric tonnes U 3 O 8 . The average U 3 O 8 content is approximately 0.02% U 3 O 8 . The exploitation of such resources would be as a byproduct of the phosphate industry and dependent on the rate of phosphate production and the capacity of triple super-phosphate plants, none of which exist at the present time. In the southern area in Paleozoic and Pre Cambrian areas there are some hopes of conventional type deposits being found but the potential appears to be small. (author)

    Geologically speaking, Lebanon is a young country since the oldest rocks are of Upper Jurassic age. Two volcanic periods are included in the more recent rocks. The country is intersected by numerous faults mainly striking NNE but also including numerous small transverse faults. No prospecting for nuclear raw materials has been recorded and there is no known activity at the present time. Lebanon has no national geological organization to support uranium prospecting. From the geological standpoint, possibilities of occurrences of nuclear minerals in Lebanon are poor and the Speculative Potential is placed in the less than 1000 tonnes uranium category. (author)

    1977-08-01

    Argentina is a predominantly lowland area of 2,789,240 square kilometers. The capital is Buenos Aires. The entire length of Argentina is bordered on the west by the Andes Mountains. Tile Northwest Andes-Piedmont region consists of deep valleys containing salt basins and volcanoes, and is an earthquake zone. Patagonia, in the south, is essentially an arid region of windy plateaus and valleys. The southern Andes are narrower and lower than the northern Andes and in the extreme south contain glaciers and ice fields. The east-central plain (Pampa) of Argentina has dry and humid sectors and contains most of the population. The largest rivers are chiefly in the northeast, many having only seasonal flow. There has been extensive surface and subsurface exploration for uranium in Argentina for over 20 years. Although most of the work has been performed by the CNEA, advisors from the U.S. and from the IAEA have also taken part. Private industry has been involved, but apparently only on a small scale. In the OECD report of 1970, it was stated that 400,000 square kilometers of Argentina appear very favorable for uranium while an additional 900,000 square kilometers offer fair possibilities. Uranium exploration to date suggests that sandstones of Permian and Cretaceous ages exposed in Western Argentina in the Cordillera are very promising for discovery of new deposits. Past CNEA estimates have indicated that there is considerable hope for new discoveries in those areas where reserves are now known. In addition to the known uraniferous provinces which are indeed favorable for further exploration, there are several other large areas that warrant attention. There are, for example, in the Santa Cruz area of about 15,500 square kilometers Cretaceous and Tertiary sediments with favorable facies for uranium deposition. In the Patagonia Cordillera, Jurassic, Cretaceous, and Tertiary sediments are of interest for prospecting, These rocks contain carbonaceous material and have been intruded by acidic rocks. The High Cordiilera, an area of 200,000 square kilometers in northwestern Argentina contains sedimentary, metamorphic, and igneous rocks that could be favorable although the difficult topography is a restrictive influence. The distribution of uranium mineralization in various sediments and other rock types over large areas of Argentina is suggestive of widespread favorability for uranium-ore formation. Inasmuch as uranium reserves plus potential are already estimated at close to 80,000 tons U 3 O 8 , and exploration has not been exhaustively conducted, ultimate resource potential might realistically be expected to fall in the 100,000 to 500,000 ton U 3 O 8 range

    The Grand Duchy of Luxembourg is a tiny, roughly triangular, sovereign state situated in Western Europe and bordered by Belgium, the Federal Republic of Germany and Prance. Its total surface area is 998 sq. miles (2,586 sq. kilometres). Its situation in Europe has made it a natural crossroads, with its language, economic interests and ways of life reflecting its close association with its neighbours. It has, however, remained a separate, if not always autonomous, political unit since the tenth century. It is one of the nine member states of the European Economic Community. The country is made up of an elevated northern tableland and a southern lower plateau. The northern section comprises part of the Ardennes mountains which continue in south-east Belgium and form a plateau generally ranging between 1,000 and 2,000 feet. Iron ore mines are located near the French border. The southern section has an elevation of below 15,000 feet and comprises mainly heavily wooded good agricultural land. There has been virtually no work done; no uranium occurrences of significance are recorded. No specific exploration for uranium in Luxembourg is apparent at the present. There are no specific regulations relating to uranium exploration,which is covered by the rules relating to mineral exploration in general

    1977-06-01

    Brazil occupies an area of about 8.5 million square kilometers -- almost half of the South American continent. The dominant geographic feature is the Amazon basin. The Amazon River and its more than 200 tributaries drain about 60 percent of the country. The basin is a vast tropical rain forest, whereas the remainder of Brazil is made up predominantly of highlands. The Central Highlands, which extends into the Amazon basin, occupies nearly all of southern Brazil and includes major mountain chains such as the Serra do Mar, Serra da Mantiqueira, and Serra do Espinhago. The Guiana Highlands fringe the northern Amazon basin and extend into Venezuela, Guyana, Surinam, and French Guiana. Lowland areas other than the Amazon basin are found in western Mato Grosso, and along the Atlantic coast from French Guiana to Uruguay. The geology of Brazil is dominated structurally and areally by three major shields composed of crystalline rocks of Archean and Proterozoic age. Collectively they comprise the Brazilian complex which is probably the largest Precambrian outcrop in the world. The complex is made up of gneisses, granites, mica schists, quartzites, dolomites, skarns, diorites, itabirites and gabbros, many of which are deeply metamorphosed. Faults, quartz veins, and dikes are common. Recurrent granitization has occurred from the Precambrian to Late Tertiary. The area of Brazil is large and its geology is favorable, in places, for every known type of uranium deposit. This is not reflected in the amount of 'known' and 'inferred' reserves -- slightly more than 21,000 tons. Rather, it is an indication of the small amount of exploration done, taking into account the large area to be covered. The speculative potential can only be guessed. It is guessed to be 500,000 tons

    In 1953, the U.S. Atomic Energy Commission, on invitation of the government of Honduras, conducted uranium reconnaissance in parts of the country. The survey consisted of scintillometric examination of all formations, veins, dikes, sills and contacts along more than 1,500 km of road. Additionally, 17 mines and prospects were examined, but in no location were uranium occurrences found. The largest and most consistently radioactive deposit noted was a body of volcanic ash at Santa Rosa de Copan, a sample of which assayed 15 ppm U 3 O 8 . A uranium prospect has been described from the Yatnala area in northwest Honduras. Uraninite and oxidation products occur in association with copper and mercury minerals in veinlets as well as disseminations in a Lower Cretaceous limestone conglomerate, the llama Formation. The llama Formation is the conglomeratic facies of the Atima (limestone) Formation, both of which are in the Yojoa Group. At the time of the U. N. development program survey in May, 1970, no uranium deposits were known in Honduras. Information is not available on current exploration in Honduras. The state owns most mineral deposits but may grant rights for exploration and exploitation of the subsoil. Mineral and surface titles are separate. Deposits of uranium and its salts, thorium and similar atomic energy substances are reserved to the state. Foreign citizens and companies, with some exceptions, may acquire mineral rights. Several groups of sediments might be of interest for uranium exploration. The Todos Santos redbeds and the El Plan Formation are both shallow marine and hence may contain marginal marine facies favorable for uranium. In the southern and central Cordillera, the Valle de Angeles sediments, particularly the sandstones, may be of interest. The contacts between Permian granites and schists (Paleozoic) may also warrant attention. Lacking further information on which to base a more optimistic outlook, it is estimated that the uranium potential of Honduras may be on the order of 1,000 to 10,000 tonnes

    Despite the high prevalence of diabetes in rural Guatemala, there is little education in diabetes self-management, particularly among the indigenous population. To address this need, a culturally relevant education intervention for diabetic patients was developed and implemented in two rural communities in Guatemala. An evaluative research project was designed to investigate if the structured, community-led diabetes self-management intervention improved selected health outcomes for participants. A one-group, pretest-posttest design was used to evaluate the effectiveness of the educational intervention by comparing measures of health, knowledge, and behavior in patients pre- and postintervention. A survey instrument assessed health beliefs and practices and hemoglobin A1c (HgA1c) measured blood glucose levels at baseline and 4 months post initiation of intervention (n = 52). There was a significant decrease (1.2%) in the main outcome measure, mean HgA1c from baseline (10.1%) and follow-up (8.9%; p = .001). Other survey findings were not statistically significant. This study illustrates that a culturally specific, diabetes self-management program led by community health workers may reduce HgA1c levels in rural populations of Guatemala. However, as a random sample was not feasible for this study, this finding should be interpreted with caution. Limitations unique to the setting and patient population are discussed in this article. © 2014 Society for Public Health Education.

    In the spirit of collaborative research, Glicken and Ford embarked on the problem of identifying the source of volcanic ash used as temper in prehistoric Maya ceramics. Verification of the presence of glass shards and associated volcanic mineralogy in thin sections of Maya ceramics was straightforward and pointed to the Guatemala Highland volcanic chain. Considering seasonal wind rose patterns, target volcanoes include those from the area west of and including Guatemala City. Joint field research conducted in 1983 by Glicken and Ford in the limestone lowlands of Belize and neighboring Guatemala, 300 km north of the volcanic zone and 150 km from the nearest identified ash deposits, was unsuccessful in discovering local volcanic ash deposits. The abundance of the ash in common Maya ceramic vessels coupled with the difficulties of long-distance procurement without draft animals lead Glicken to suggest that ashfall into the lowlands would most parsimoniously explain prehistoric procurement; it literally dropped into their hands. A major archaeological problem with this explanation is that the use of volcanic ash occurring over several centuries of the Late Classic Period (ca. 600-900 AD). To accept the ashfall hypothesis for ancient Maya volcanic ash procurement, one would have to demonstrate a long span of consistent volcanic activity in the Guatemala Highlands for the last half of the first millennium AD. Should this be documented through careful petrographic, microprobe and tephrachronological studies, a number of related archaeological phenomena would be explained. In addition, the proposed model of volcanic activity has implications for understanding volcanism and potential volcanic hazards in Central America over a significantly longer time span than the historic period. These avenues are explored and a call for further collaborative research of this interdisciplinary problem is extended in this paper.

    Diabetes self-management education (DSME) is a fundamental element of type 2 diabetes care. Although 75% of adults with diabetes worldwide live in low-income and middle-income countries (LMICs), limited DSME research has been conducted in LMICs. The objective of this study was to evaluate a home-based DSME intervention in rural Guatemala. We conducted a prospective study of a DSME intervention using a quasi-experimental, single-group pretest-posttest design. We enrolled 90 participants in the intervention, which consisted of 6 home visits (May 2014-July 2016) conducted by a diabetes educator using a curriculum culturally and linguistically tailored to rural Mayan populations. Primary outcomes were changes in mean hemoglobin A1c (HbA1c) and mean systolic and diastolic blood pressure at baseline and at 12 months. Secondary outcomes were diabetes knowledge and self-care activities at baseline and intervention completion. HbA1c decreased significantly from baseline to 12 months (absolute mean change, -1.5%; 95% confidence interval [CI], -1.9% to -1.0%; P Guatemala. Our findings point to the need for more DSME research in resource-limited settings globally.

    Weight-related stigma is established as a major psychosocial stressor and correlate of depression among people living with obesity in high-income countries. Anti-fat beliefs are rapidly globalizing. The goal of the study is to (1) examine how weight-related stigma, enacted as teasing, is evident among women from a lower-income country and (2) test if such weight-related stigma contributes to depressive symptoms. Modeling data for 12,074 reproductive-age women collected in the 2008-2009 Guatemala National Maternal-Infant Health Survey, we demonstrate that weight-related teasing is (1) experienced by those both underweight and overweight, and (2) a significant psychosocial stressor. Effects are comparable to other factors known to influence women's depressive risk in lower-income countries, such as living in poverty, experiencing food insecurity, or suffering sexual/domestic violence. That women's failure to meet local body norms-whether they are overweight or underweight-serves as such a strong source of psychological distress is particularly concerning in settings like Guatemala where high levels of over- and under-nutrition intersect at the household and community level. Current obesity-centric models of weight-related stigma, developed from studies in high-income countries, fail to recognize that being underweight may create similar forms of psychosocial distress in low-income countries.

    Migration of Maya refugees to the United States since the late 1970s affords the opportunity to study the consequences of life in a new environment on the growth of Maya children. The children of this study live in Indiantown, Florida, and Los Angeles, California. Maya children between 4 and 14 years old (n = 240) were measured for height, weight, fatness, and muscularity. Overall, compared with reference data for the United States, the Maya children are, on average, healthy and well nourished. They are taller and heavier and carry more fat and muscle mass than Maya children living in a village in Guatemala. However, they are shorter, on average, than children of black, Mexican-American, and white ethnicity living in Indiantown. Children of Maya immigrants born in the United States tend to be taller than immigrant children born in Guatemala or Mexico. Families that invest economic and social resources in their children have taller children. More economic successful families have taller children. Migration theory and political economy theory from the social sciences are combined with plasticity theory and life history theory (parental investment) from biology to interpret these data.

    Full Text Available ABSTRACT Objective To document the prevalence of patients on hemodialysis in southwestern Guatemala who have chronic kidney disease (CKD of non-traditional causes (CKDnt. Methods This cross-sectional descriptive study interviewed patients on hemodialysis at the Instituto Guatemalteco de Seguridad Social on their health and occupational history. Laboratory serum, urine and vital sign data at the initiation of hemodialysis were obtained from chart reviews. Patients were classified according to whether they had hypertension or obesity or neither. The proportion of patients with and without these traditional CKD risk factors was recorded and the association between demographic and occupational factors and a lack of traditional CKD risk factors analyzed using multivariate logistic regression. Results Of 242 total patients (including 171 non-diabetics enrolled in hemodialysis in southwestern Guatemala, 45 (18.6% of total patients and 26.3% of non-diabetics lacked traditional CKD risk factors. While agricultural work history was common, only travel time greater than 30 minutes and age less than 50 years old were significantly associated with CKD in the absence of traditional risk factors. Individuals without such risk factors lived throughout southwestern Guatemala’s five departments. Conclusions The prevalence of CKDnT appears to be much lower in this sample of patients receiving hemodialysis in Southwestern Guatemala than in hospitalized patients in El Salvador. It has yet to be determined whether the prevalence is higher in the general population and in patients on peritoneal dialysis.

    The recent expansion of antiretroviral treatment (ART) coverage in middle/low-income countries has been associated with increasing prevalence of HIV pre-ART drug resistance (PDR). We assessed PDR prevalence, patterns, and trends in Guatemala. Blood samples from 1,084 ART-naive individuals, enrolled from October 2010 to December 2013 at the Roosevelt Hospital in Guatemala City, were obtained. PDR was evaluated using the WHO mutation list for transmitted drug resistance (TDR) surveillance. An overall PDR prevalence of 7.3% (95% CI 5.8-9.0%) was observed for the whole study period. TDR to nonnucleoside reverse transcriptase inhibitors (NNRTI) was the highest (4.9%, p500 and 350-500 CD4(+) T cells/μl (7.4% and 8.7%, respectively) compared to individuals with Guatemala remains at an intermediate level. Nevertheless, we have shown evidence suggesting increasing trends in NNRTI PDR, which need to be taken into account in national HIV management policies.

    Full Text Available La presencia africana en la Audiencia de Guatemala en los siglos XVI y XVII ha sido poco estudiada. Por lo tanto, en este trabajo se analizarán los diferentes mecanismos que utilizó la corona española para el traslado de esclavos, como las licencias y el sistema de asientos. Asimismo, se estudiará la inserción de los africanos en la sociedad colonial y principalmente su interrelación con la población indígena nativa de la región. En los documentos coloniales referentes a matrimonios, podemos observar los procesos de "interculturalidad" en los cuales el esclavo africano intercambió elementos culturales que influyeron en la música. Tal fue el caso de la marimba, instrumento que dio identidad a la región de estudio. Por último, se pretende observar, a través del análisis de las narrativas indígenas originadas en la década de los 90' del siglo XX, cómo en la cosmovisión indígena aún continúa la presencia de los "negros".The presence of African population at the "Audiencia" of Guatemala between 16th and 17th centuries has been vaguely studied by historians and other social scientists. This paper emphasizes on several ways -as slave trade licenses and 'asientos'- that were used by the Spanish Crown for slave trade and transportation. In addition, this article analyses the integration of African slaves and their descendents in Colonial Mexican society, especially their mixture with indigenous population. In Colonial records, as marriages and baptisms files, it is possibly to regard a profound influence on inter-cultural processes between African people and the rest of the Colonial casts. As an example, the musical instrument 'marimba' that brought cultural identity to Guatemala 'Audiencia'. Finally, in this article we will analyze the indigenous literature of the last decade of the 20th century, in which is clear the evidence of "negro" agents in indigenous cosmology.

    Full Text Available OBJECTIVE: Severe physical punishment of children is an important issue in international child health and welfare. This study examines such punishment in Guatemala and El Salvador. METHODS: Data came from nationally representative surveys of women aged 15-49 and men aged 15-59 residing in Guatemala (2002 and El Salvador (2002-2003. The surveys included questions about punishment experienced during childhood, with response options ranging from verbal scolding to beating. In Guatemala, parents were asked how they disciplined their children; questions allowed them to compare how they were punished in their childhood with how they punished their own children. Bivariate and multivariate analyses are presented. RESULTS: In Guatemala, 35% of women and 46% of men reported being beaten as punishment in childhood; in El Salvador, the figures were 42% and 62%, respectively. In both countries, older participants were relatively more likely than younger participants to have been beaten as children. Witnessing familial violence was associated with an increased risk of being beaten in childhood. In Guatemala, having experienced physical punishment as a child increased the chance that parents would use physical punishment on their own children. Multivariate analyses revealed that women who were beaten in childhood were significantly more likely in both countries to be in a violent relationship. CONCLUSIONS: The use of beating to physically punish children is a common problem in Guatemala and El Salvador, with generational and intergenerational effects. Its negative and lingering effects necessitate the introduction of policies and programs to decrease this behavior.OBJETIVOS: El castigo físico severo de niños es un tema importante de la salud y el bienestar infantil en el mundo. En el presente estudio se analiza este tipo de castigo en Guatemala y El Salvador. MÉTODOS: Se tomaron los datos de encuestas representativas nacionales realizadas a mujeres de 14 a

    While the Guatemalan Truth Commission came to the conclusion that agents of the state had committed acts of genocide in the early 1980s, fundamental questions remain. Should we indeed speak of the massacres committed between 1981 and 1983 in Guatemala as 'genocide', or would 'ethnocide' be the more appropriate term?

    2010-01-01

    The advanced very high resolution radiometer (AVHRR) and moderate resolution imaging spectroradiometer (MODIS) data are being widely used for vegetation monitoring across the globe. However, sensors will discontinue collecting these data in the near future. National Aeronautics and Space Administration is planning to launch a new sensor, visible infrared imaging radiometer suite (VIIRS), to continue to provide satellite data for vegetation monitoring. This article presents a case study of Guatemala and compares the simulated VIIRS-Normalized Difference Vegetation Index (NDVI) with MODIS-NDVI for four different dates each in 2003 and 2005. The dissimilarity between VIIRS-NDVI and MODIS-NDVI was examined on the basis of the percent difference, the two-tailed student's t-test, and the coefficient of determination, R 2. The per cent difference was found to be within 3%, the p-value ranged between 0.52 and 0.99, and R 2 exceeded 0.88 for all major types of vegetation (basic grains, rubber, sugarcane, coffee and forests) found in Guatemala. It was therefore concluded that VIIRS will be almost equally capable of vegetation monitoring as MODIS.

    It is important to identify stereotypes about indigenous people because those stereotypes influence prejudice and discrimination, both obstacles to social justice and universal human rights. The purpose of the current study was to document the stereotypes, as held by Guatemalan adolescents, of indigenous Maya people (e.g., Maya) and nonindigenous Ladinos in Guatemala (the 2 main ethnic groups in Guatemala). Guatemalan adolescents (N = 465; 38.3% female; Mage = 14.51 years; SDage = 1.81 years) provided drawings and written characteristics about indigenous Maya and nonindigenous Ladino people, which were then coded for patterns in the data. These patterns included negative stereotypes, such as the Maya being lazy and Ladina women being weak; and positive stereotypes, such as the Maya being caring and warm and Ladino men being successful. There were also interactions between the participants' own gender and ethnicity and how they depicted the target they were assigned. For example, male participants were unlikely to depict male targets of either ethnicity engaging in homemaking activities. Finally, there was evidence of in-group bias based both on gender and ethnicity. These findings suggest that perhaps because indigenous groups around the world share some common negative stereotypes, an understanding of these stereotypes will aid in decreasing prejudice and discrimination against indigenous people, could reduce intergroup conflict, and increase access to basic human rights.

    Background Human metapneumovirus (HMPV) is an important cause of acute respiratory infections (ARI), but little is known about how it compares with respiratory syncytial virus (RSV) in Central America. Objectives In this study, we describe hospitalized cases of HMPV- and RSV-ARI in Guatemala. Methods We conducted surveillance at three hospitals (November 2007–December 2012) and tested nasopharyngeal and oropharyngeal swab specimens for HMPV and RSV using real-time reverse transcription-polymerase chain reaction. We calculated incidence rates, and compared the epidemiology and outcomes of HMPV-positive versus RSV-positive and RSV-HMPV-negative cases. Results We enrolled and tested specimens from 6288 ARI cases; 596 (9%) were HMPV-positive and 1485 (24%) were RSV-positive. We observed a seasonal pattern of RSV but not HMPV. The proportion HMPV-positive was low (3%) and RSV-positive high (41%) for age Guatemala, but HMPV hospitalizations are less frequent than RSV and, in young children, less severe than other etiologies. Preventive interventions should take into account the wide variation in incidence by age and unpredictable timing of incidence peaks. PMID:24761765

    to examine the present-day knowledge formation and practice of indigenous Kaqchikel-speaking midwives, with special attention to their interactions with the Guatemalan medical community, training models, and allopathic knowledge in general. a qualitative study consisting of participant-observation in lay midwife training programs; in-depth interviews with 44 practicing indigenous midwives; and three focus groups with midwives of a local non-governmental organization. Kaqchikel Maya-speaking communities in the Guatemalan highlands. the cumulative undermining effects of marginalization, cultural and linguistic barriers, and poorly designed training programs contribute to the failure of lay midwife-focused initiatives in Guatemala to improve maternal-child health outcomes. Furthermore, in contrast to prevailing assumptions, Kaqchikel Maya midwives integrate allopathic obstetrical knowledge into their practice at a high level. as indigenous midwives in Guatemala will continue to provide a large fraction of the obstetrical services among rural populations for many years to come, maternal-child policy initiatives must take into account that: (1)Guatemalan midwife training programs can be significantly improved when instruction occurs in local languages, such as Kaqchikel, and (2)indigenous midwives' increasing allopathic repertoire may serve as a productive ground for synergistic collaborations between lay midwives and the allopathic medical community.

    Guatemala, as a party to the Framework Convention on Tobacco Control (FCTC), is required to regulate cigarette packaging and labeling and eliminate illicit tobacco trade. Current packaging and labeling characteristics (of legal and illegal cigarettes) and their compliance with the FCTC is unknown. We sought to analyze package and label characteristics of illegal and legal cigarettes sold in Guatemala. We visited the 22 largest traditional markets in the country to purchase illegal cigarettes. All brands registered on tobacco industry websites were purchased as legal cigarettes. Analysis compared labeling characteristics of illegal and legal packs. Most (95%) markets and street vendors sold illegal cigarettes; 104 packs were purchased (79 illegal and 25 legal). Ten percent of illegal and none of the legal packs had misleading terms. Half of the illegal packs had a warning label covering 26 to 50% of the pack surface. All legal packs had a label covering 25% of the surface. Illegal packs were more likely to have information on constituents and emissions (85% vs. 45%, p Guatemala, neither illegal nor legal cigarette packs comply with FCTC labeling mandates. Urgent implementation and enforcement of the FCTC is necessary to halt the tobacco epidemic.

    The present project started as an educational exercise for the Renewable Energies and Environment Masters given by the Polytechnic University of Madrid (UPM). It has been developed in collaboration with the research centre CIEMAT, the NGO Energy without Borders (ESF) and the University UPM, with the purpose of analyzing in a real context the application of Geographic Information Systems in renewable energies regional integration. The final aim of our study is to provide the isolated communities, specifically 13 communities in Alta Verapaz (Department of Coban, Guatemala), with the necessary conditions of electrification. This improvement will make possible the sustainable development of the area. Through the analysis of the geographic, technical and economic information gathered, using the IntiGIS methodology we will identify which is the most suitable autonomous generating system to cover the basic needs of the rural population in these Guatemalan communities.

    Members of the Cryptotis goldmani group of small-eared shrews (Mammalia, Soricomorpha, Soricidae) represent a clade within the genus that is characterized by modifications of the forelimb that include broadened forefeet, elongated and broadened foreclaws, and massive humeri with enlarged processes. These modifications are consistent with greater adaptation to their semifossorial habits than other members of the genus. The species in this group occur discontinuously in temperate highlands from southern Tamaulipas, Mexico, to Honduras. In Guatemala, there are three species: the relatively widespread Cryptotis goodwini and two species (Cryptotis lacertosus, Cryptotis mam) endemic to highland forests in the Sierra de los Cuchumatanes of western Guatemala. Ongoing studies focusing on the relationships of variation in cranial and postcranial skeletal morphology have revealed a fourth species from remnant cloud forest in the Sierra de Yalijux, central Guatemala. In this paper, I describe this new species and characterize its morphology relative to other species in the C. goldmani group and to other species of Cryptotis in Guatemala. In addition, I summarize available details of its habitat and ecology.

    Background: The role of meteorological factors on influenza transmission in the tropics is less defined than in the temperate regions. We assessed the association between influenza activity and temperature, specific humidity and rainfall in 6 study areas that included 11 departments or provinces within 3 tropical Central American countries: Guatemala, El Salvador and Panama. Method/ Findings: Logistic regression was used to model the weekly proportion of laboratory-confirmed influenza positive samples during 2008 to 2013 (excluding pandemic year 2009). Meteorological data was obtained from the Tropical Rainfall Measuring Mission satellite and the Global Land Data Assimilation System. We found that specific humidity was positively associated with influenza activity in El Salvador (Odds Ratio (OR) and 95% Confidence Interval of 1.18 (1.07-1.31) and 1.32 (1.08-1.63)) and Panama (OR = 1.44 (1.08-1.93) and 1.97 (1.34-2.93)), but negatively associated with influenza activity in Guatemala (OR = 0.72 (0.6-0.86) and 0.79 (0.69-0.91)). Temperature was negatively associated with influenza in El Salvador's west-central departments (OR = 0.80 (0.7-0.91)) whilst rainfall was positively associated with influenza in Guatemala's central departments (OR = 1.05 (1.01-1.09)) and Panama province (OR = 1.10 (1.05-1.14)). In 4 out of the 6 locations, specific humidity had the highest contribution to the model as compared to temperature and rainfall. The model performed best in estimating 2013 influenza activity in Panama and west-central El Salvador departments (correlation coefficients: 0.5-0.9). Conclusions/Significance: The findings highlighted the association between influenza activity and specific humidity in these 3 tropical countries. Positive association with humidity was found in El Salvador and Panama. Negative association was found in the more subtropical Guatemala, similar to temperate regions. Of all the study locations, Guatemala had annual mean temperature and specific

  12. Will hydrogen be competitive in Europe without tax favours?

    Hydrogen is one of the alternative transport fuels expected to replace conventional oil based fuels. The paper finds that it is possible for non-fossil-based hydrogen to become the lowest cost fuel without favourable tax treatment. The order of per kilometre cost depends on performance in hydrogen production, the international oil price, and fuel taxes. At low oil prices, the highest per kilometre costs were found for non-fossil power-based hydrogen, the second highest for natural gas-based hydrogen, and the lowest for conventional fuels. At high oil prices, this ranking is reversed and non-fossil power-based hydrogen becomes the most cost competitive fuel. General fuel taxes lower the threshold at which the international oil price reverses this competitiveness order. The highest fuel tax rates applied in Europe lowers this threshold oil price considerably, whereas the lowest fuel taxes may be insufficient to make hydrogen competitive without tax favours. Alternative adjustments of the EU minimum fuel tax rates with a view to energy efficiency and CO 2 -emissions are discussed.

    Correlative species distribution models are based on the observed relationship between species' occurrence and macroclimate or other environmental variables. In climates predicted less favourable populations are expected to decline, and in favourable climates they are expected to persist. However, little comparative empirical support exists for a relationship between predicted climate suitability and population performance. We found that the performance of 93 populations of 34 plant species worldwide - as measured by in situ population growth rate, its temporal variation and extinction risk - was not correlated with climate suitability. However, correlations of demographic processes underpinning population performance with climate suitability indicated both resistance and vulnerability pathways of population responses to climate: in less suitable climates, plants experienced greater retrogression (resistance pathway) and greater variability in some demographic rates (vulnerability pathway). While a range of demographic strategies occur within species' climatic niches, demographic strategies are more constrained in climates predicted to be less suitable. © 2017 The Authors.

The investigated channels of the reaction were nπ + π + π - π - , pπ + π - π - π 0 and pπ + π - π - . The effective mass distributions of the products of the reaction were presented. The results of the paper pointed out that 5/2 isobars could be produced in the first channel which corresponded the Feynman diagram with the Δ - (1232) exchange.

    The study aimed to review the results of endovascular aneurysm repair (EVAR) using a novel sac-anchoring endoprosthesis in patients with favourable and adverse anatomy. This is a prospective, multicentre, clinical trial. The Nellix endoprosthesis consists of dual, balloon-expandable endoframes, surrounded by polymer-filled endobags, which obliterate the aneurysm sac and maintain endograft position. The study reviewed worldwide clinical experience and Core Lab evaluation of computed tomography (CT) scans. From 2008 to 2010, 34 patients (age 71 ± 8 years, abdominal aortic aneurysm (AAA) diameter 5.8 ± 0.8 cm) were treated at four clinical sites. Seventeen patients (50%) met the inclusion criteria for Food and Drug Administration (FDA)-approved endografts (favourable anatomy); 17 (50%) had one or more adverse anatomic feature: neck length 60° (9%) and iliac diameter >23 mm (38%). Device deployment was successful in all patients; iliac aneurysm treatment preserved hypogastric patency. Perioperative mortality was 1/34 (2.9%); one patient died at 10 months of congestive heart failure (CHF); one patient had a secondary procedure at 15 months. During 15 ± 6 months follow-up, there were no differences in outcome between favourable and adverse anatomy patients. Follow-up CT extending up to 2 years revealed no change in aneurysm size or endograft position and no new endoleaks. Favourable and adverse anatomy patients can be successfully treated using the Nellix sac-anchoring endoprosthesis. Early results are promising but longer-term studies are needed.

    The question whether euthanasia should be legalised has led to substantial public debate in France. The objective of this study in a sample of French physicians was to establish the potential determinants of a favourable opinion about euthanasia in general and when faced with a specific situation as embodied in the Humbert affair. The study was a cross-sectional survey investigating two different samples of medical doctors: (1) those specialised in palliative care and affiliated to the French Society for Patient Accompaniment and Palliative Care; (2) medical interns (medical doctors in training course) in a French medical university (Marseille). A questionnaire was sent (email) to each voluntary participant including sociodemographics, professional status, mention of believing in God, and opinion about euthanasia (the question was designed to assess the general opinion about euthanasia and the opinion about a specific case, the Vincent Humbert' case (a man who was rendered quadriplegic, blind, and mute after an accident and has requested euthanasia). A total of 413 physicians participated in the research (participation rate: 48.5%). Less than half of the population were favourable to euthanasia in general and almost two-thirds of the population were favourable to Vincent Humbert's request for euthanasia. Based on the multivariate analysis, individuals believing in God and being a medical intern were significant independent factors linked to having a favourable opinion about euthanasia in general and about the Vincent Humbert's request. There is still no study in France on the development of opinion about euthanasia and its impact. The issue goes beyond the strictly professional sphere and involves broader socio-political stakes. These stakes do not necessarily take into account medical practices and experiences or the desires of end-of-life patients. The professional upheaval that the future French legal framework will doubtlessly trigger will require further

    Full Text Available EP is one crucial aspect of the employment relationship in both private and public organisations in many countries.

So far, this model has only been applied in developed countries such as the United States of America, United Kingdom, Australia and Europe.

No extensive study has been conducted using this model to explain worker participation practices at the company level. In parallel with this aspect, this model also has never been used to explain the nature of EP in the Asian developing countries. This current research will use the Favourable Conjunctures Model to examine the nature of EP in private enterprises based on empirical study carried out in Malaysia. The argument of this paper is that the Favourable Conjunctures Model of Industrial Democracy (Poole et al. 2001 is inadequate to elucidate the characteristics of EP in Malaysia. Based on empirical findings from three private companies in Malaysia, the paper argues that there are many contextual factors that influence the nature of EP in Malaysian private companies that are not taken into account by the model. They are:multi-ethnic (cultural influences, the repressive role of state in the Malaysian industrial relations, the New Economic Policy and industrialisation plan, Islamic working ethics, the influence of a British colonial history, lack of training among non-managerial employees in EP, the impact of foreign direct investment on industrial relations, to identify a few. Based on this study, it is proposed that the present Favourable Conjunctures Model of Industrial Democracy (Poole et al. 2001 be modified based on the contextual factors discussed above. The paper concludes that the western model of EP could not be directly applied in Malaysia without some adjustment of

    In this study, we evaluate the effect of participatory Ecohealth interventions on domestic reinfestation of the Chagas disease vector Triatoma dimidiata after village-wide suppression of the vector population using a residual insecticide. The study was conducted in the rural community of La Brea, Guatemala between 2002 and 2009 where vector infestation was analyzed within a spatial data framework based on entomological and socio-economic surveys of homesteads within the village. Participatory interventions focused on community awareness and low-cost home improvements using local materials to limit areas of refuge and alternative blood meals for the vector within the home, and potential shelter for the vector outside the home. As a result, domestic infestation was maintained at ≤ 3% and peridomestic infestation at ≤ 2% for 5 years beyond the last insecticide spraying, in sharp contrast to the rapid reinfestation experienced in earlier insecticide only interventions.

    Objective To assess whether the National Tuberculosis Program (NTP) guidelines for culture and drug sensitivity testing (DST) in Guatemala were successfully implemented, particularly in cases of smear-negative pulmonary tuberculosis (TB) or previously treated TB, by documenting notification rates by department (geographic area), disease type and category, and culture and DST results. Methods This was a cross-sectional, operational research study that merged and linked all patients registered by the NTP and the National Reference Laboratory in 2013, eliminating duplicates. The proportions with culture (for new smear negative pulmonary cases) and culture combined with DST (for previously treated patients) were estimated and analyzed by department. Data were analyzed using EpiData Analysis version 2.2. Results There were 3 074 patients registered with TB (all forms), for a case notification rate of 20/100 000 population. Of these, 2 842 had new TB, of which 2 167 (76%) were smear-positive pulmonary TB (PTB), 385 (14%) were smear-negative PTB, and 290 (10%) were extrapulmonary TB. There were 232 (8%) previously treated cases. Case notification rates (all forms) varied by department from 2-68 per 100 000 population, with the highest rates seen in the southwest and northeast part of Guatemala. Of new TB patients, 136 had a culture performed and 55 had DST of which the results were 33 fully sensitive, 9 monoresistant, 3 polyresistant, and 10 multidrug resistant TB (MDR-TB). Only 21 (5%) of new smear-negative PTB patients had cultures. Of 232 previously treated patients, 54 (23%) had a culture and 47 (20%) had DST, of which 29 were fully sensitive, 7 monoresistant, 2 polyresistant, and 9 MDR-TB. Of 22 departments (including the capital), culture and DST was performed in new smear-negative PTB in 7 departments (32%) and in previously treated TB in 13 departments (59%). Conclusions Despite national guidelines, only 5% of smear-negative PTB cases had a culture and only 20% of

    Guatemala is a multiethnic and multilingual country located in Central America. The main population groups separate 'Ladinos' (mixed Native American-African-Spanish), and Native indigenous people of Maya descent. Among the present-day Guatemalan Maya, there are more than 20 different ethnic groups separated by different languages and cultures. Genetic variation of these communities still remains largely unexplored. The principal aim of this study is to explore the genetic variability of the Maya and 'Ladinos' from Guatemala by means of uniparental and ancestry informative markers (AIMs). Analyses of uniparental genetic markers indicate that Maya have a dominant Native American ancestry (mitochondrial DNA [mtDNA]: 100%; Y-chromosome: 94%). 'Ladino', however, show a clear gender-bias as indicated by the large European ancestry observed in the Y-chromosome (75%) compared to the mtDNA (0%). Autosomal polymorphisms (AIMS) also mirror this marked gender-bias: (i) Native American ancestry: 92% for the Maya vs. 55% for the 'Ladino', and (ii) European ancestry: 8% for the Maya vs. 41% for the 'Ladino'. In addition, the impact of the Trans-Atlantic slave trade on the present-day Guatemalan population is very low (and only occurs in the 'Ladino'; mtDNA: 9%; 4%), in part mirroring the fact that Guatemala has a predominant orientation to the Pacific Ocean instead of a Caribbean one. Sequencing of entire Guatemalan mitogenomes has led to improved Native American phylogeny via the addition of new haplogroups that are mainly observed in Mesoamerica and/or the North of South America. The data reveal the existence of a fluid gene flow in the Mesoamerican area and a predominant unidirectional flow towards South America, most likely occurring during the Pre-Classic (1800 BC-200 AD) and the Classic (200-1000 AD) Eras of the Mesoamerican chronology, coinciding with development of the most distinctive and advanced Mesoamerican civilization, the Maya.

  8. Paleoecological Calibration In Central Guatemala: Modern Pollen Rain From Bryophyte Polsters And Surface Sediments

    Paleoecology requires understanding the correspondences between modern pollen rain and local-regional vegetation, in order to develop accurate paleovegetation reconstructions. Paleoecology in Guatemala has been developed largely over decades in the northern lowlands in close relationship with Classic Maya archaeology, where paleoenvironmental reconstructions have been made mainly through the use of fossil pollen. Scarcity of calibration studies in the Mesoamerican region however remains evident; nevertheless, they are necessary to produce reliable reconstructions. We present calibration pollen data from two locations in Central Guatemala: Lachua Lowlands and Purulha Highlands. Pollen spectra were analyzed from surface sediments samples (SS) from a lake and a small pond in Lachua, a river floodplain and a lake shore in Purulha. Bryophyte polsters samples (BP) were collected from the interior of minimally disturbed forests in both Lachua (rain forest) and Purulha (cloud forest). Pollen spectra between SS and BP differed in both locations. Analysis per location indicates that SS were more similar for Purulha, as compared to Lachua. Combined analysis of locations indicates that SS from both locations were related to anemophilous taxa - great production of pollen quantities that has high dispersion capacities-. This provides evidence that the pollen signal from SS is probably more regional than local. BP from Lachua and Purulha differed notably in their pollen signal, each location containing local taxa, tropical and temperate respectively. Some temperate anemophilous taxa were better represented in Lachua than in Purulha. Purulha SS were similar, and contained more taxa related to disturbance and anemophilous taxa. The arboreal pollen (AP) to non-arboreal (NAP) ratio (AP/NAP) of both SS and BP corresponded with the tree- prevalent landscape in Lachua. The SS AP/NAP ratio represented the deforested landscape of the river floodplain and lake environments in Purulha

    Objectives This study investigated the association of the familial coexistence of child stunting and maternal overweight with indigenous women in Guatemala. Methods We selected 2388 child-mother pairs from the data set of the Living Standards Measurement Study conducted in Guatemala in 2000. This study examined the association between maternal and household characteristics and the nutritional status of children aged 6-60 months and mothers aged 18-49 years by using multivariable logistic regression models. Results Compared with non-indigenous households, a significantly higher percentage of indigenous households exhibited stunted child and overweight mother (SCOM) pairs (15.9 vs. 22.2%). Compared with normal-weight mothers, overweight mothers were less likely to have stunted children [adjusted odds ratio (AOR) 0.66, 95% confidence interval (CI) 0.50-0.88]. However, compared with mothers who were not short and overweight, short and overweight mothers were significantly more likely to have stunted children (AOR 1.80, 95% CI 1.19-2.73) and were more likely to be indigenous women living in urban areas (AOR 3.01, 95% CI 1.19-7.60) or rural areas (AOR 3.02, 95% CI 1.28-7.14). The order of observed prevalence of SCOM pairs in different types of households was as follows: urban indigenous (25.0%), rural indigenous (21.2%), rural non-indigenous (19.8%), and urban non-indigenous households (10.7%). Conclusions for Practice Urban indigenous households were more likely to have SCOM pairs. This study provided useful information for identifying the most vulnerable groups and areas with a high prevalence of the familial coexistence of child stunting and maternal overweight.

    The use of non-crop plants to provide the resources that herbivorous crop pests’ natural enemies need is being increasingly incorporated into integrated pest management programs. We evaluated insect functional groups found on three refuges consisting of five different plant species each, planted next to a maize crop in Lima, Peru, to investigate which refuge favoured natural control of herbivores considered as pests of maize in Peru, and which refuge plant traits were more attractive to those desirable enemies. Insects occurring in all the plants, including the maize crop itself, were sampled weekly during the crop growing cycle, from February to June 2011. All individuals collected were identified and classified into three functional groups: herbivores, parasitoids, and predators. Refuges were compared based on their effectiveness in enhancing the populations of predator and parasitoid insects of the crop enemies. Refuges A and B were the most effective, showing the highest richness and abundance of both predators and parasitoids, including several insect species that are reported to attack the main insect pests of maize (Spodoptera frugiperda and Rhopalosiphum maidis), as well as other species that serve as alternative hosts of these natural enemies.

    Health inequalities disproportionally affect indigenous people in Guatemala. Previous studies have noted that the disadvantageous situation of indigenous people is the result of complex and structural elements such as social exclusion, racism and discrimination. These elements need to be addressed in order to tackle the social determinants of health. This research was part of a larger participatory collaboration between Centro de Estudios para la Equidad y Gobernanza en los Servicios de Salud (CEGSS) and community based organizations aiming to implement social accountability in rural indigenous municipalities of Guatemala. Discrimination while seeking health care services in public facilities was ranked among the top three problems by communities and that should be addressed in the social accountability intervention. This study aimed to understand and categorize the episodes of discrimination as reported by indigenous communities. A participatory approach was used, involving CEGSS's researchers and field staff and community leaders. One focus group in one rural village of 13 different municipalities was implemented. Focus groups were aimed at identifying instances of mistreatment in health care services and documenting the account of those who were affected or who witnessed them. All of the 132 obtained episodes were transcribed and scrutinized using a thematic analysis. Episodes described by participants ranged from indifference to violence (psychological, symbolic, and physical), including coercion, mockery, deception and racism. Different expressions of discrimination and mistreatment associated to poverty, language barriers, gender, ethnicity and social class were narrated by participants. Addressing mistreatment in public health settings will involve tackling the prevalent forms of discrimination, including racism. This will likely require profound, complex and sustained interventions at the programmatic and policy levels beyond the strict realm of public

    Full Text Available This paper reflects on the significance of the legal treatment of sexual violence in contexts of armed conflict. What are the physical and emotional effects of the widespread use of rape as a weapon of war? In what way are women objectified and how are the implications of this projected into the social reference group? In order to answer these questions, first, a review is made of the international standards of legal protection against sexual violence. Then two case studies are analysed: Sepur Zarco in Guatemala and Manta and Vilca in Peru. In these cases,for the first time, national legal systems, based on international humanitarian law, have established a legal basis to punish sexual violence crimes within armed conflict contexts as crimes against humanity.

    For the first time, the reduviid bug Triatoma ryckmani Zeledón and Ponce (Hemiptera; Reduviidae) was recorded to inhabit the epiphyte Tillandsia xerographica Rohweder (Bromeliaceae) in the semiarid region of Guatemala. These bromeliads grow mainly in drought-resistant trees with rough bark such as Pereskia lychnidiflora (Cactaceae). In our study site, we investigated 30 T. xerographica, and 53 specimens of T. ryckmani were found. Most T. ryckmani (68.5%) were unfed. Ants (Formicidae) were the predominant (92.2%) insect taxon in T. xerographica. Other insects such as Blattidae (3.0%), Reduviidae (T. ryckmani: 2.5%), Blaberidae (2.2%), Gryllidae (0.1%), and Acrididae (0.1%) were recorded in the bromeliads. T. xerographica is illegally commercialized without previous inspection. This may cause accidental introduction of T. ryckmani to houses and to other countries.

    Full Text Available The new Guatemala de la Asunción, has been impacted by climate change, due to its geographical location, the tectonic plates and volcanic features of the soil, which causes that the country is always threatened by tragic events that occur suddenly and on a recurring basis, by natural events (volcanic eruptions, earthquakes, hurricanes, storms, floods, landslides. Because the age of the District of La Candelaria, (since it is the second set in the Valle de la Ermita, after the transfer of the city in January 1776, likewise it was one of the areas damaged by the earthquake of February 4, 1976, has as a consequence that the architectural heritage of the District of La Candelaria is constantly at risk. In the 21st century, the problems of nationwide architectural heritage have additional components that make it more vulnerable to ruin, (social, economic and political deterioration, insecurity, which added to the poor state of physical buildings, referred to the lack of maintenance, little financial support and interest of the authorities to apply the laws for the protection of immovable cultural heritage assets. Within the Barrio of La Candelaria, there are homes and architectural remains, which could improve its current state. Guatemala needs to join the State and private institutions to ensure prevention and safeguarding of the heritage.

    Full Text Available Maya spiritual practice in Guatemala has been actively challenged by mainstream religions and by pressures originating from other institutions. Many Maya ritualists have been directly reproached by religious leaders and have been targeted by a state apparatus that associates rural Maya life with insurgency. As a result, many Maya spiritual elements have been pushed to, and kept at, the margins of society. Focusing on the past two decades, this essay reviews how Mayas nevertheless maintain an active ritual life. They do this by engaging in a close relationship with the spirit-owners of the landscape, beings upon whom humans depend for their sustenance and life. They do this, also, in the face of many challenges from organized religions, the educational system, and the military. Having considered the effects of these institutions upon Maya spirituality, I then put forward some concerns Mayas face when addressing how to value and promote Maya spiritual practices in Guatemala. In addition to encouraging young Mayas to uphold their heritage, Mayas may need to prevail upon Catholic and evangelical Protestant congregations to suspend judgment about Maya spirituality and to acknowledge its far-reaching importance in culturally pluralistic society.

    No data are available regarding the success of DNA Short Tandem Repeat (STR) profiling from degraded skeletal remains in Guatemala. Therefore, DNA profiling success rates relating to 2595 skeletons from eleven cases at the Forensic Anthropology Foundation of Guatemala (FAFG) are presented. The typical postmortem interval was 30 years. DNA was extracted from bone powder and amplified using Identifiler and Minifler. DNA profiling success rates differed between cases, ranging from 50.8% to 7.0%, the overall success rate for samples was 36.3%. The best DNA profiling success rates were obtained from femur (36.2%) and tooth (33.7%) samples. DNA profiles were significantly better from lower body bones than upper body bones (p = <0.0001). Bone samples from males gave significantly better profiles than samples from females (p = <0.0001). These results are believed to be related to bone density. The findings are important for designing forensic DNA sampling strategies in future victim recovery investigations. © 2016 American Academy of Forensic Sciences.

  4. Unraveling the history of complex zoned garnets from the North Motagua Mélange (Guatemala)

    The Guatemala Suture Zone (GSZ) is situated in central Guatemala, between the North American and Caribbean plates. Two serpentinite mélanges straddle the Motagua Fault system: the North Motagua Mélange (NMM) and the South Motagua Mélange (SMM). In this study, chemically zoned garnet grains from four eclogite blocks from the NMM were analyzed by EMPA for major elements and LA-ICP-MS for trace elements to unravel the geological history of the eclogites. These eclogites typically consist of euhedral to subhedral garnets, partly retrogressed omphacite grains, and accessory minerals such as phengite and epidote as inclusions in garnet. EBSD was employed to examine apparent garnet inclusions in garnet. The garnet grains in NMM eclogites display complex chemical zonations: all grains roughly show a spessartine-rich core, an almandine-rich core and/or intermediate zone, and a pyrope and grossular-rich rim. Additionally, crystal resorption can be observed between the different zones, and the pyrope-grossular rim can display oscillatory zoning. Finally, grossular-rich zones (crystallographically syntactic) within garnet are present in all studied samples. REE and spider diagrams do not show any significant difference in the patterns of the different zones within the garnet, or indicating that the chemical environment from which each garnet zone grew was broadly the same. The lack of significant variation in LILE content indicates that a fluid influx during garnet growth is unlikely. Consequently, we interpret that garnet grains grew in a largely closed system; however, the presence of the grossular-rich zones, argues for occasional excursions into conditions when either two garnets crystallized or Ca-rich overgrowths that were largely resorbed prior to subsequent continued garnet growth.

    In August 2014, the Centre for the Studies of Equity and Governance in Health Systems (CEGSS) in Guatemala launched an online platform, which facilitates complaints about health services via text messages. The aim is to collect, systemise and forward such complaints to relevant institutions, and to create a data pool on perceived deficits of health care in rural Guatemala. To evaluate if the online platform is an accepted, user-friendly and efficient medium to engage citizens in the reporting of health care deficiencies in Guatemala. The general study design of this research was a mixed-method approach including a quantitative analysis of complaints received and a qualitative exploration of the attitude of community leaders towards the platform. User statistics showed that a total of N = 228 messages were sent to the platform in the period August 2014-March 2015. The majority of complaints (n = 162, 71%) fell under the 'lack of drugs, equipment or supplies' category. The community leaders welcomed the platform, describing it as modern and progressive. Despite feedback mechanisms and methods to respond to complaints not yet being fully developed, many users showed a high intrinsic motivation to use the new tool. Others, however, were restrained by fear of personal consequences and distrust of the state's judicial system. Access to mobile phones, reception, and phone credit or battery life did not pose major obstacles, but the producing and sending of correctly formatted messages was observed to be difficult. The online platform paired with SMS technology appears to be a viable approach to collect citizens' complaints in health care and connect citizens with relevant institutions. Further studies should be conducted to quantify follow-up activities and the impact on local health care provision.

  6. The Diffusion of Labour Standards: The Case of the US and Guatemala

    Full Text Available The number of free trade agreements (FTAs concluded by the United States of America (US has grown vastly over the past two decades. While FTAs contribute to increased global competition and as such may also contribute to socially-undesirable practices in the area of working conditions and the environment, the proliferation in FTAs has paradoxically also augmented the potential for making free trade more fair as some of these agreements now include labour provisions. However, the question is whether these trade agreements have also actually diffused internationally recognised labour standards. This article studies the FTA the US signed in 2004 with a number of Central American countries and which, at a later stage, also included the Dominican Republic. This FTA is commonly referred to as CAFTA-DR and includes a chapter on labour standards. The article argues that the effects of the inclusion of labour standards in CAFTA-DR have been limited and therefore should be viewed as an unsuccessful attempt at policy transfer. This is illustrated by the case of Guatemala, a country known for its lack of respect for labour standards and which is currently the subject of a complaints procedure under the CAFTA-DR. It is maintained that this lack of effectiveness is the result of many factors. Among these is the weakness of the labour chapter of CAFTA-DR resulting from the fact that the chapter is the outcome of bargaining processes both within the US and between the US and Guatemala, where symbolic results were valued more highly than actual substance.

    Guatemala harbors three species of primates (Alouatta palliata, Alouatta pigra and Ateles geoffroyi), but the distribution and state of conservation of populations of these species are poorly documented. In the case of A. pigra, populations have been studied recently and documented in several sites in Mexico and Belize, and only in one site in Guatemala (Tikal National Park). In this study, we report first-time population data for A. pigra existing in the Lachuá Eco-region in northwestern Guatemala. Surveys were conducted between September 2002 and April 2003 in the northern portion (32 km2) of the Lachuá National Park (LLNP; 145 km2) and in a fragmented landscape north of the protected area. In this latter area we surveyed a large forest fragment (17.14 km2), "Nueve Cerros", and 26 small forest fragments that ranged in size from 0.01 to 3.9 km2. Surveys resulted in a total count of 414 howler monkeys of which 403 belonged to 80 mixed-sex groups, four were solitary males, two were solitary females and five were found in two male groups. Standardized sampling effort among sites indicated 16.7 monkeys/100 survey hours at LLNP, 35.8 individuals/100 survey hours at "Nueve Cerros" and 71.0+/-62.2 individuals/100 survey hours in the forest fragments. Mean group size varied from 4.07 individuals at LLNP to 5.19 individuals in the forest fragments. Conservation problems for the black howler population surveyed are discussed, along with possible conservation scenarios.

    In some contemporary populations, fertility levels appear to plateau, with women maintaining a consistently high level of fertility for a relatively extended period. Because this plateau does not reflect the historical patterns observed in Europe, the focus of most studies on fertility patterns, mechanisms underlying the plateau and the reinstatement of a decline have not been fully explored and are not fully understood. Through the construction of fertility histories of 25,000 women using multiple years of health survey data, we analyze some of the components of stalled fertility as they pertain to Guatemala, the only Central American country to have experienced a stalled fertility decline.

    This study explored perceived benefits and risks of participation in HIV research among 33 female sex workers in Tecun Uman, Guatemala. Stigma associated with sex work and HIV was a critical barrier to research participation. Key benefits of participation included access to HIV/STI prevention and testing, as well as positive and trusting relationships between sex workers and research teams. Control exerted by managers had mixed influences on perceived research risks and benefits. Results underscore the critical need for HIV investigators to develop population-tailored procedures to reduce stigma, engage managers, and reinforce trusting, reciprocal relationships between sex work communities and researchers.

    conhecimento sobre o problema da droga na Guatemala. É necessário realizar, no futuro, estudos qualitativos e quantitativos sobre esse tema.This quantitative and qualitative research describes the perspective of families and relatives of drug abusers in seven Latin American countries. In Guatemala, most of the people affected by the drug problem is multidrug abusers. Marijuana, followed by cocaine and benzodiazepines are the most used drugs. Of the respondents, 46% think drug use is a personal choice. They also recognize family as the most important protective factor, friends who use drugs and peer pressure are the major risk factors. The study reveals that the population believes that the response of the health services is insufficient, and that the preventive initiatives are not available or not properly addressed. The results show the need of more studies to update the knowledge of the drug problem in Guatemala. Future qualitative and quantitative research is needed to address the theme.

    Full Text Available Southern Mexico and Central America have many water bodies of different morphology and water chemistry with an interesting zooplankton fauna, originating from North or South America. A set of 63 samples, taken in 2005 and 2008, from water bodies of the Yucatan Peninsula karst, Belize and Guatemala, were studied for the content of calanoid copepods. Old and recent literature was used to determine animals to species level. Drawings were prepared with a microscope and a camera lucida. A total of 32 samples with totally six species contained calanoid copepods: one estuarine pseudodiaptomid and five freshwater diaptomids. Pseudodiaptomus marshi was found at different salinities. It is confirmed that the commonest diaptomids in the Yucatan Peninsula are Arctodiaptomus dorsalis and Mastigodiaptomus nesus. The former was also recorded from Lake Amatitlan. Mastigodiaptomus nesus is as widespread as A. dorsalis but it is absent from the Lake Peten area in Guatemala. Mastigodiaptomus reidae was found in two shallow habitats, these specimens differ from those from the type locality by having a set of peculiar large spine-like processes on the last thoracic and the urosome segments of the females. Leptodiaptomus siciloides was found only in Lake Ayarza with high salinity. Prionodiaptomus colombiensis occurred in the highlands of Guatemala in Lago de Güija and in the Peten area in Laguna Sacpuy. We contributed with our occurrence records to a better knowledge of the geographic distribution of some calanoid copepods. Morphological findings in some species are of value for taxonomic differentiation between species.El sur de México y América Central tienen varios cuerpos de agua con diferente morfología, composición química y una interesante fauna de zooplancton procedente de América del Norte o del Sur.

    Full Text Available The railway has advantages over other branches of longdistancetransportation from the ecological, economic, safety,and technological point of view.The paper gives an evaluation of the favourable influenceof railway traffic on the environment reflected in the rationalenergy consumption, significantly reduced need of physicalspace, and reduced air pollution.Having these data in mind, the railway is considered tohave a negligible influence on environmental pollution. However,studying even such small amounts plays a significant rolein the traffic safety and in the lives of people and nature itself

    As the first large subduction thrust earthquake off the coast of western Guatemala in the past 50 years, the 7 November 2012 Mw=7.4 earthquake offers the first opportunity for a geodetic study of coseismic and postseismic behavior for a segment of the Middle America trench where frictional coupling makes a transition from weak coupling off the coast of El Salvador to strong coupling in southern Mexico. Processing of continuous GPS measurements at 19 stations in Guatemala, El Salvador, and southern Mexico, and at 7 campaign points in Guatemala defines a highly consistent pattern of coseismic offsets during the earthquake, ranging from 47±5 mm of SW movement just inland from the earthquake epicenter to a few mm at sites located in northern Guatemala. Inversions of these offsets to find their best-fitting fault-slip solution in an elastic half space give a geodetic earthquake moment ranging between 0.75 and 1.1 x 1020 Nm, slightly smaller than the seismic estimates that range between 1.2 and 1.45 x 1020 Nm. Slip inversion using a constant slip model, assuming 293° and 29° for the fault azimuth and dip angle, indicates a nearly reverse slip of 2.8 m (rake 78°) on a fault plane 42 km-long and 20 km-wide, centered at 26 km depth. A variable slip inversion indicates that slip concentrated above depths of 40 km may have extended updip to the trench and reached a maximum of only 0.8 m, less than one-sixth the maximum slip indicated by a recent slip solution (5.3 m) obtained from waveform inversion of seismological data. Detailed model comparisons will be discussed. Transient postseismic displacements have been recorded at the nearby continuous GPS sites with amplitudes reaching 20-25 mm at some stations. The duration of the phenomenon is short: using an exponential-decay model, the estimated decay time is 90 ± 10 days. This postseismic signal is consistent with afterslip along a significantly broader area (+50%) of the subduction interface than ruptured coseismically

    Leishmania braziliensis is endemic in Guatemala and Belize in Central America. To help identify the vector(s) of this parasite in Guatemala, phlebotomine sand flies that were aspirated from the clothing of collectors at Tikal National Park in the Department of the Peten were examined for flagellates. Lutzomyia ovallesi was found infected with flagellates that were identified as L. braziliensis by isoenzyme electrophoresis. The isoenzyme profile of this isolate matched those from humans from the same area.

Con información diaria para el periodo 1996-2008, se concluye que solamente las intervenciones de compra produjeron una disminución de la volatilidad de largo plazo del tipo de cambio quetzal/dólar, pero que ambos tipos de intervención afectaron el quetzal. En relación con los objetivos establecidos por el banco central, la intervención cambiaria fue efectiva cuando se orientó a moderar el tipo de cambio, pero careció de efectividad cuando ésta se limitó a moderar la volatilidad cambiaria sin afectar su tendencia.

    West Nile virus ecology has yet to be rigorously investigated in the Caribbean Basin. We identified a transmission focus in Puerto Barrios, Guatemala, and established systematic monitoring of avian abundance and infection, seroconversions in domestic poultry, and viral infections in mosquitoes. West Nile virus transmission was detected annually between May and October from 2005 to 2008. High temperature and low rainfall enhanced the probability of chicken seroconversions, which occurred in both urban and rural sites. West Nile virus was isolated from Culex quinquefasciatus and to a lesser extent, from Culex mollis/Culex inflictus, but not from the most abundant Culex mosquito, Culex nigripalpus. A calculation that combined avian abundance, seroprevalence, and vertebrate reservoir competence suggested that great-tailed grackle (Quiscalus mexicanus) is the major amplifying host in this ecosystem. West Nile virus transmission reached moderate levels in sentinel chickens during 2007, but less than that observed during outbreaks of human disease attributed to West Nile virus in the United States.

    To describe levels of risky sexual behaviour, HIV testing and HIV knowledge among men and women in Guatemala by ethnic group and to identify adjusted associations between ethnicity and these outcomes. Data on 16,205 women aged 15-49 and 6822 men aged 15-59 from the 2008-2009 Encuesta Nacional de Salud Materno Infantil were used to describe ethnic group differences in sexual behaviour, HIV knowledge and testing. We then controlled for age, education, wealth and other socio-demographic factors in a multivariate logistic regression model to examine the effects of ethnicity on outcomes related to age at sexual debut, number of lifetime sex partners, comprehensive HIV knowledge, HIV testing and lifetime sex worker patronage (men only). The data show low levels of risky sexual behaviour and low levels of HIV knowledge among indigenous women and men, compared to other respondents. Controlling for demographic factors, indigenous women were more likely than other women never to have been tested for HIV and to lack comprehensive HIV knowledge. They were less likely to report early sexual debut and three or more lifetime sexual partners. Indigenous men were more likely than other men to lack comprehensive HIV knowledge and demonstrated lower odds of early sexual debut, 10 or more lifetime sexual partners and sex worker patronage. The Mayan indigenous population in Guatemala, while broadly socially vulnerable, does not appear to be at elevated risk for HIV based on this analysis of selected risk factors. Nonetheless, low rates of HIV knowledge and testing may be cause for concern. Programmes working in indigenous communities should focus on HIV education and reducing barriers to testing. Further research into the factors that underlie ethnic self-identity and perceived ethnicity could help clarify the relative significance of these measures for HIV risk and other health outcomes.

    Concerns remain about lower effectiveness and waning immunity of rotavirus vaccines in resource-poor populations. We assessed vaccine effectiveness against rotavirus in Guatemala, where both the monovalent (RV1; 2-dose series) and pentavalent (RV5; 3-dose series) vaccines were introduced in 2010. A case-control evaluation was conducted in 4 hospitals from January 2012 to August 2013. Vaccine status was compared between case patients (children with laboratory-confirmed rotavirus diarrhea) and 2 sets of controls: nondiarrhea "hospital" controls (matched by birth date and site) and nonrotavirus "test-negative" diarrhea controls (adjusted for age, birth month/year, and site). Vaccine effectiveness ([1 - odds ratio of vaccination] × 100%) was computed using logistic regression models. We evaluated 213 case patients, 657 hospital controls, and 334 test-negative controls. Effectiveness of 2-3 doses of a rotavirus vaccine against rotavirus requiring emergency department visit or hospitalization was 74% (95% confidence interval [CI], 58%-84%) with hospital controls, and 52% (95% CI, 26%-69%) with test-negative controls. Using hospital controls, no significant difference in effectiveness was observed between infants 6-11 months (74% [95% CI, 18%-92%]) and children ≥12 months of age (71% [95% CI, 44%-85%]) (P= .85), nor between complete courses of RV1 (63% [95% CI, 23%-82%]) and RV5 (69% [95% CI, 29%-87%]) (P= .96). An uncommon G12P[8] strain, partially heterotypic to strains in both vaccines, was identified in 89% of cases. RV1 and RV5 were similarly effective against severe rotavirus diarrhea caused by a heterotypic strain in Guatemala. This supports broader implementation of rotavirus vaccination in low-income countries where >90% global deaths from rotavirus occur.

    Limited empirical evidence exists for how economic conditions affect micronutrient nutrition. We hypothesized that increasing poverty and rising food prices would reduce consumption of high-quality "luxury" foods, leading to an increased probability of inadequacy for several nutrients. The 2006 Guatemala National Living Conditions Survey was analyzed. First, energy and nutrient intakes and adequacy levels were calculated. Second, the income-nutrient relationships were investigated by assessing disparities in intakes, determining income-nutrient elasticities, and modeling nutrient intakes by reductions in income. Third, the food price-nutrient relationships were explored through determination of price-nutrient elasticities and modeling 2 price scenarios: an increase in food prices similar in magnitude to the food price crisis of 2007-2008 and a standardized 10% increase across all food groups. Disparities in nutrient intakes were greatest for vitamin B-12 (0.38 concentration index) and vitamin A (0.30 concentration index); these nutrients were highly and positively correlated with income (r = 0.22-0.54; P < 0.05). Although the baseline probability of inadequacy was highest for vitamin B-12 (83%), zinc showed the greatest increase in probability of inadequacy as income was reduced, followed by folate and vitamin A. With rising food prices, zinc intake was most acutely affected under both scenarios (P < 0.05) and folate intake in the poorest quintile (+7 percentage points) under the 10% scenario. Price-nutrient elasticities were highest for vitamin B-12 and the meat, poultry, and fish group (-0.503) and for folate and the legumes group (-0.343). The economic factors of food prices and income differentially influenced micronutrient intakes in Guatemala, notably zinc and folate intakes.

    Information on folate and vitamin B12 deficiency rates in Guatemala is essential to evaluate the current fortification program. The objectives of this study were to describe the prevalence of folate and vitamin B12 deficiencies among women of childbearing age (WCBA) in Guatemala and to identify vulnerable populations at greater risk for nutrient deficiency. A multistage cluster probability study was designed with national and regional representation of nonpregnant WCBA (15-49 years of age). Primary data collection was carried out in 2009-2010. Demographic and health information was collected through face-to-face interviews. Blood samples were collected from 1473 WCBA for serum and red blood cell (RBC) folate and serum vitamin B12. Biochemical concentrations were normalized using geometric means. Prevalence rate ratios were estimated to assess relative differences among different socioeconomic and cultural groups including ethnicity, age, education level, wealth index and rural versus urban locality. National prevalence estimates for deficient serum [Guatemala, folate deficiency was more prevalent among indigenous rural and urban poor populations. Vitamin B12 deficiency was widespread among WCBA. Our results suggest the ongoing need to monitor existing fortification programs, in particular regarding its reach to vulnerable populations.

    Waterfowl species are known to harbor the greatest diversity of low pathogenicity influenza A virus (LPAIV) subtypes and are recognized as their main natural reservoir. In Guatemala there is evidence of circulation of LPAIV in wild ducks; however, the bird species contributing to viral diversity during the winter migration in Central America are unknown. In this study, samples obtained from 1250 hunter-killed birds from 22 different species were collected on the Pacific coast of Guatemala during three winter migration seasons between 2010 and 2013. Prevalence of LPAIV detected by real-time reverse-transcriptase polymerase chain reaction was 38.2%, 23.5%, and 24.7% in the 2010-11, 2011-12, and 2012-13 seasons, respectively. The highest virus prevalence was detected in the northern shoveler (Anas clypeata), followed by the blue-winged teal (Anas discors). The majority of positive samples and viral isolates were obtained from the blue-winged teal. Analysis of LPAIV prevalence over time in this species indicated a decreasing trend in monthly prevalence within a migration season. Sixty-eight viruses were isolated, and nine HA and seven NA subtypes were identified in 19 subtype combinations. In 2012-13 the most prevalent subtype was H14, a subtype identified for the first time in the Western Hemisphere in 2010. The results from this study represent the most detailed description available to date of LPAIV circulation in Central America.

    Full Text Available To select the proper interventions that could prevent maternal mortality, adequate and appropriate maternal mortality data are needed. Nevertheless, the quality and quantity of information and the scope of maternal health- and death-related data are inadequate in many countries, particularly in the developing world. From January 1993 to December 1996 a surveillance program in maternal mortality was developed to conduct surveillance studies in the department of Guatemala, Guatemala. With an active surveillance system, our approach gave a more complete picture of maternal death and produced information on the specific causes of maternal mortality. Using multiple sources of information, we reviewed and analyzed all deaths of women of childbearing age (10 to 49 years. Each death was investigated to determine whether it was pregnancy-related or not. The maternal mortality ratio for the four-year study period was 156.2 deaths per 100 000 live births. Women 35 and older had a higher risk of maternal death than women under that age. Women who were 35-39 years old had a maternal death risk almost three times as high as women aged 20-24. For women who were 40 or older the risk was more than double that of women 20-24 years old. Overall, the two leading causes of maternal mortality were infection and hemorrhage. Vaginal deliveries where there was medical assistance had the highest rate of delivery-related maternal death from general infection. In deliveries attended by nonmedical personnel, delivery-related maternal deaths from hemorrhage were most frequently associated with retained placenta. Developing countries are called on to implement systems that can provide continuous and systematic data collection so that policymakers and health managers have adequate information to design proper interventions to save women's lives.Para poder elegir aquellas intervenciones que podrían prevenir la mortalidad materna, se necesitan datos apropiados y de calidad

    The cost of mosquito repellents in Latin America has discouraged their wider use among the poor. To address this problem, a low-cost repellent was developed that reduces the level of expensive repellent actives by combining them with inexpensive fixatives that appear to slow repellent evaporation. The chosen actives were a mixture of para-menthane-diol (PMD) and lemongrass oil (LG). To test the efficacy of the repellent, field trials were staged in Guatemala and Peru. Repellent efficacy was determined by human-landing catches on volunteers who wore the experimental repellents, control, or 15% DEET. The studies were conducted using a balanced Latin Square design with volunteers, treatments, and locations rotated each night. In Guatemala, collections were performed for two hours, commencing three hours after repellent application. The repellent provided >98% protection for five hours after application, with a biting pressure of >100 landings per person/hour. The 15% DEET control provided lower protection at 92% (p 46 landings per person/hour. The 20% DEET control provided significantly lower protection at 64% (p < 0.0001). In both locations, the PMD/LG repellent provided excellent protection up to six hours after application against a wide range of disease vectors including Anopheles darlingi. The addition of fixatives to the repellent extended its longevity while enhancing efficacy and significantly reducing its cost to malaria-endemic communities.

    This dissertation makes use of a physical geography perspective to examine the relationship between agriculture and climate in Guatemala using dendrochronology. I examined the potential of high-resolution climate proxy data from dendrochronology to help fill in the gaps of past climate information to better understand the natural and anthropogenic variability of precipitation which, in turn, can inform Guatemala's agriculture sector. This research has demonstrated successful cross-dating and climate sensitivity of Abies guatemalensis in the Pacific slope of Guatemala. Based on this, I have produced a 124-year record of mean precipitation from June-July-August. The mean precipitation from June-July-August at this site seems to receive an important influence from the sea surface temperature (SST) in the Pacific Ocean in the form of El Nino-Southern Oscillation (ENSO) in the region 3.4. The analysis on the frequency of the precipitation records suggests that single year droughts dominate the record yet, periods of 9 years below-average rainfall can persist. Likewise, single year pluvial events also dominate the evaluated period. The long-term reconstruction of precipitation allowed to describe past relationships between coffee plantations and pests. For instance, the frequency analysis suggests that 4 or more consecutive periods of above-average precipitation are associated with several coffee pests and subsequently great economical losses due to crop failures, including the last coffee leaf rust crisis. This study also presents a streamflow reconstruction of the Upper Samala River watershed using a tree ring-width chronology derived from the Guatemalan fir (Abies guatemalensis) to reconstruct mean August-September-October streamflow volumes for the period 1889-2013. Our analysis shows that strong statistical correlations are present between tree-ring width measurements and monthly natural streamflow series. The mean August-September-October streamflow variability is

    Infants and children in developing countries bear the burden of diarrheal disease. Diarrheal disease is linked to unsafe drinking water and can result in serious long-term consequences, such as impaired immune function and brain growth. There is evidence that point-of-use water filtration systems reduce the prevalence of diarrhea in developing countries. In the summer of 2014, following community forums and interactive workshops, water filters were distributed to 71 households in a rural Maya community in Guatemala. The purpose of this study was to evaluate the uptake of tabletop water filtration systems to reduce diarrheal diseases. A descriptive correlational study was used that employed community partnership and empowerment strategies. One year postintervention, in the summer of 2015, a bilingual, interdisciplinary research team conducted a house-to-house survey with families who received water filters. Survey data were gathered from the head of household on family demographics, current family health, water filter usage, and type of flooring in the home. Interviews were conducted in Spanish and in partnership with a village leader. Each family received a food package of household staples for their participation. Descriptive statistics were calculated for all responses. Fisher's exact test and odds ratios were used to determine relationships between variables. Seventy-nine percent (n = 56) of the 71 households that received a water filter in 2014 participated in the study. The majority of families (71.4%; n = 40) were using the water filters and 16 families (28.6%) had broken water filters. Of the families with working water filters, 15% reported diarrhea, while 31% of families with a broken water filter reported diarrhea. Only 55.4% of the homes had concrete flooring. More households with dirt flooring and broken water filters reported a current case of diarrhea. A record review of attendees at an outreach clinic in this village noted a decrease in intestinal

    This paper reports on the study of geothermal exploration and geothermal development in the nation of Guatemala that is being led by the Instituto Nacionai de electrificacion (INDE) through the Unidad de Desarrollo Geotermico (UDG), for the purpose of developing the geothermal resources in order to generate electricity. Since 1972, it has accomplished geoscientific studies with regional surveys in 13 areas located in the volcanic region in the southern part of the country. Also, prefeasibility studies have been carried out in geothermal areas such as Moyuta and Tecuamburro in the southeast of the country; Amatitlan in the central region and San Marcos in the west. Moreover, in the geothermal field of Zunil I, which is located in the western Department of Quetzaltenango, the feasibility study has been completed, and the first geothermo-electric plant of 15 MW is being schedule for June of 1993. By then, the feasibility study for the second power plant in the more promising area of Zunil II located on the outskirts of Zunil I or Amatitlan. Also, in the area of Zunil I a farm-produce dehydration plant has been built through a technical cooperation agreement between INDE and Los Alamos National Laboratory, LANL. It has the purpose of showing the use of direct-heat through produced steam from the slim hole Z-11

    Full Text Available Manipulations of the serotonin transmission during early development induce long-lasting changes in the serotonergic circuitry throughout the brain. However, little is known on the developmental consequences in the female progeny. Therefore, this study aimed at exploring the behavioural effects of pre- and postnatal stimulation of the serotonergic system by 5-methoxytryptamine in adolescent female rats on behavioural reactivity and anxiety- like phenotype. Our results show that perinatal 5- methoxythyptamine decreased total distance travelled and rearing frequency in the novel enviroment, and increased the preference for the centre of the arena in the open field test. Moreover, perinatal 5-methoxytryptamine increased the percentages of entries and time spent on the open arms of the elevated plus maze, with respect to perinatally vehicle-exposed rats. Thus, perinatal stimulation of serotonin receptors does not impair the functional response to the emotional challenges in female rats, favouring the occurrence of a stress-resilient phenotype.

    Understanding the complex processes that drive volcanic unrest is crucial to effective risk mitigation. Characterization of these processes, and the mechanisms of volcanic eruptions, is only possible when high-resolution geophysical and geological observations are available over comparatively long periods of time. In November 2014, the Liverpool Earth Observatory, UK, in collaboration with the Instituto Nacional de Sismologia, Meteorologia e Hidrologia (INSIVUMEH), Guatemala, established a multi-parameter geophysical network at Santiaguito, one of the most active volcanoes in Guatemala. Activity at Santiaguito throughout the past decade, until the summer of 2015, was characterized by nearly continuous lava dome extrusion accompanied by frequent and regular small-to-moderate gas or gas-and-ash explosions. Over the past two years our network collected a wealth of seismic, acoustic and deformation data, complemented by campaign visual and thermal infrared measurements, and rock and ash samples. Here we present preliminary results from the analysis of this unique dataset. Using acoustic and thermal data collected during 2014-2015 we were able to assess volume fractions of ash and gas in the eruptive plumes. The small proportion of ash inferred in the plumes confirms estimates from previous, independent, studies, and suggests that these events did not involve significant magma fragmentation in the conduit. The results also agree with the suggestion that sacrificial fragmentation along fault zones in the conduit region, due to shear-induced thermal vesiculation, may be at the origin of such events. Finally, starting in the summer of 2015, our experiment captured the transition to a new phase of activity characterized by vigorous vulcanian-style explosions producing large, ash-rich, plumes and frequent hazardous pyroclastic flows, as well as the formation a large summit crater. We present evidence of this transition in the geophysical and geological data, and discuss its

    Patient reminder systems are an evidence-based way to improve childhood vaccination rates but are difficult to implement in low- and middle-income countries (LMICs). Short Message Service (SMS) texts may offer a potential low-cost solution, especially in LMICs where mobile phones are becoming more ubiquitous. To determine if an SMS-based vaccination reminder system aimed at improving completion of the infant primary immunization series is feasible and acceptable in Guatemala. A pilot randomized controlled trial was conducted at two public health clinics in Guatemala City. Infants aged 8-14 weeks presenting for the first dose of the primary immunization series were enrolled in March-April 2013. Participants randomized into the intervention received three SMS reminders one week before the second and third dose. A follow-up acceptability survey was administered to both groups. The participation rate was 86.8% (321/370); 8 did not own a cell phone and 12 could not use SMS. 96.9% of intervention parents were sent at least one SMS reminder prior to visit 2 and 96.3% prior to visit 3. Both intervention and usual care participants had high rates of vaccine and visit completion, with a non-statistically significant higher percentage of children in the intervention completing both visit 2 (95.0% vs. 90.1%, p=.12) and visit 3 (84.4% vs. 80.7%, p=.69). More intervention vs. usual care parents agreed that SMS reminders would be helpful for remembering appointments (p<.0001), agreed to being interested in receiving future SMS reminders (p<.0001), and said that they would be willing to pay for future SMS reminders (p=.01). This proof of concept evaluation showed that a new application of SMS technology is feasible to implement in a LMIC with high user satisfaction. Larger studies with modifications in the SMS system are needed to determine effectiveness (Clinical Trial Registry NCT01663636). Copyright © 2016 The Authors. Published by Elsevier Ltd..

    Consequences of exposure to household air pollution (HAP) from biomass fuels used for cooking on neonatal deaths and stillbirths is poorly understood. In a large multi-country observational study, we examined whether exposure to HAP was associated with perinatal mortality (stillbirths from gestation week 20 and deaths through day 7 of life) as well as when the deaths occurred (macerated, non-macerated stillbirths, very early neonatal mortality (day 0-2) and later neonatal mortality (day 3-28). Questions addressing household fuel use were asked at pregnancy, delivery, and neonatal follow-up visits in a prospective cohort study of pregnant women in rural communities in five low and lower middle income countries participating in the Global Network for Women and Children's Health's Maternal and Newborn Health Registry. The study was conducted between May 2011 and October 2012. Polluting fuels included kerosene, charcoal, coal, wood, straw, crop waste and dung. Clean fuels included electricity, liquefied petroleum gas (LPG), natural gas and biogas. We studied the outcomes of 65,912 singleton pregnancies, 18 % from households using clean fuels (59 % LPG) and 82 % from households using polluting fuels (86 % wood). Compared to households cooking with clean fuels, there was an increased risk of perinatal mortality among households using polluting fuels (adjusted relative risk (aRR) 1.44, 95 % confidence interval (CI) 1.30-1.61). Exposure to HAP increased the risk of having a macerated stillbirth (adjusted odds ratio (aOR) 1.66, 95%CI 1.23-2.25), non-macerated stillbirth (aOR 1.43, 95 % CI 1.15-1.85) and very early neonatal mortality (aOR 1.82, 95 % CI 1.47-2.22). Perinatal mortality was associated with exposure to HAP from week 20 of pregnancy through at least day 2 of life. Since pregnancy losses before labor and delivery are difficult to track, the effect of exposure to polluting fuels on global perinatal mortality may have previously been underestimated. Clinical

    Programmes to modify the safety culture have led to lasting improvements in patient safety and quality of care in high-income settings around the world, although their use in low-income and middle-income countries (LMICs) has been limited. This analysis explores (1) how to measure the safety culture using a health culture survey in an LMIC and (2) how to use survey data to develop targeted safety initiatives using a paediatric nephrology unit in Guatemala as a field test case. We used the Safety, Communication, Operational Reliability, and Engagement survey to assess staff views towards 13 health climate and engagement domains. Domains with low scores included personal burnout, local leadership, teamwork and work-life balance. We held a series of debriefings to implement interventions targeted towards areas of need as defined by the survey. Programmes included the use of morning briefings, expansion of staff break resources and use of teamwork tools. Implementation challenges included the need for education of leadership, limited resources and hierarchical work relationships. This report can serve as an operational guide for providers in LMICs for use of a health culture survey to promote a strong safety culture and to guide their quality improvement and safety programmes.

    A 23-year-old indigenous Guatemalan man presented in 2016 to our clinic in Sololá, Guatemala, with 10 months of recurrent neck swelling, fevers, night sweats and weight loss. Previously, he had sought care in three different medical settings, including a private physician-run clinic, a tertiary private cancer treatment centre and, finally, a rural government health post. With assistance from our institution's accompaniment staff, the patient was admitted to a public tertiary care hospital for work-up. Rifampin-susceptible tuberculosis was diagnosed, and appropriate treatment was begun. The case illustrates how low tuberculosis recognition among community health workers and health system segmentation creates obstacles to appropriate care, especially for patients with limited means. As a result, significant diagnostic and treatment delays can occur, increasing the public health burden of tuberculosis. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    2013-05-01

    This paper estimates rural household-level forest reliance in the western highlands of Guatemala using quantitative methods. Data were generated by the way of an in-depth household income survey, repeated quarterly between November 2005 and November 2006, in 11 villages ( n = 149 randomly selected households). The main sources of income proved to be small-scale agriculture (53 % of total household income), wages (19 %) and environmental resources (14 %). The latter came primarily from forests (11 % on average). In the poorest quintile the forest income share was as high as 28 %. All households harvest and consume environmental products. In absolute terms, environmental income in the top quintile was 24 times higher than in the lowest. Timber and poles, seeds, firewood and leaf litter were the most important forest products. Households can be described as `regular subsistence users': the share of subsistence income is high, with correspondingly weak integration into regional markets. Agricultural systems furthermore use important inputs from surrounding forests, although forests and agricultural uses compete in household specialization strategies. We find the main household determinants of forest income to be household size, education and asset values, as well as closeness to markets and agricultural productivity. Understanding these common but spatially differentiated patterns of environmental reliance may inform policies aimed at improving livelihoods and conserving forests.

  18. Migration to the Maya Biosphere Reserve, Guatemala: Why place matters.

    2008-01-01

    Virtually all migration research examines international migration or urbanization. Yet understudied rural migrants are of critical concern for environmental conservation and rural sustainable development. Despite the fact that a relatively small number of all migrants settle remote rural frontiers, these are the agents responsible for perhaps most of the tropical deforestation on the planet. Further, rural migrants are among the most destitute people worldwide in terms of economic and human development. While a host of research has investigated deforestation resulting from frontier migration, and a modest literature has emerged on frontier development, this article explores the necessary antecedent to tropical deforestation and poverty along agricultural frontiers: out-migration from origin areas. The data come from a 2000 survey with community leaders and key informants in 16 municipios of migrant origin to the Maya Biosphere Reserve (MBR), Petén, Guatemala. A common denominator among communities of migration origin to the Petén frontier was unequal resource access, usually land. Nevertheless, the factors driving resource scarcity were widely variable. Land degradation, land consolidation, and population growth prevailed in some communities but not in others. Despite similar exposure to community and regional level push factors, most people in the sampled communities did not out-migrate, suggesting that any one or combination of factors is not necessarily sufficient for out-migration.

  19. Environmental and Archaeological Research in the Peten, Guatemala

    1999-01-01

    The Peten, Northern Guatemala, was once inhabited by a population of several million Maya before their collapse in the 9th century A.D.. The seventh and eight centuries were a time of crowning glory four millions of Maya; by 930 A.D. only a few scattered houses remained, testifying to the greatest disaster in human history. What is known is that at the time of their collapse the Maya had cut down most of their trees. After centuries of regeneration the Peten now represent the largest remaining tropical forest in Central America but is experiencing rapid deforestation in the wake of an invasion of settlers. The successful adaptive techniques of the indigenous population are being abandoned in favor of the destructive techniques of monoculture and cattle raising. Remote sensing and Geographic Information System (GIS) analysis are being used to address issues in Maya archeology as well as monitor the effects of increasing deforestation in the area today. One thousand years ago the forests of the Peten were nearly destroyed by the ancient Maya who after centuries of successful adaptation finally overused their resources. Current inhabitants are threatening to do the same thing today in a shorter time period with a lesser population. Through the use of remote sensing/GIS analysis we are attempting to answer questions about the past in order to protect the resources of the future.

    Full Text Available The herpetofaunal richness of San Julian Universitary Farm (FUSJ, in Patulul, Suchitepequez, Guatemala, was investigated using three methods: (1 Capture/sighting of specimens, (2 social inquiry and (3 desk research. The field work was distributed over a 10 year period (2003-2013 at a rate of six fieldwork sessions each year. A 4.5 km long transect extending through the agricultural landscape of the farm was run repeatedly. Each fieldwork session included diurnal and nocturnal travels. The accumulated search time was 420 hr-transect. The equivalent to 337.5 of accumulated miles were traveled, including elevations between 1490 and 1833 feet above sea level. Three former hunters were interviewed and asked to identify species they think are present at the FUSJ. Published data were reviewed to determine which species were expected to occur in San Julian. Two lists (amphibians andreptiles totaling 97 species (including 95 expected, 38 found and 2 not expected was generated. The quality and significance of our data is discussed.

  1. The voice of Holland: Dutch public and patient's opinion favours single-port laparoscopy.

    Single-port laparoscopy is prospected as the future of minimal invasive surgery. It is hypothesised to cause less post operative pain, with a shorter hospitalisation period and improved cosmetic results. Population- and patient-based opinion is important for the adaptation of new techniques. This study aimed to assess the opinion and perception of a healthy population and a patient population on single-port laparoscopy compared with conventional laparoscopy. An anonymous 33-item questionnaire, describing conventional and single-port laparoscopy, was given to 101 patients and 104 healthy volunteers. The survey participants (median age 44 years; range 17-82 years) were asked questions about their personal situation and their expectations and perceptions of the two different surgical techniques; conventional multi-port laparoscopy and single-port laparoscopy. A total of 72% of the participants had never heard of single-port laparoscopy before. The most important concern in both groups was the risk of surgical complications. When complication risks remain similar, 80% prefers single-port laparoscopy to conventional laparoscopy. When the risk of complications increases from 1% to 10%, 43% of all participants prefer single-port laparoscopy. A total of 70% of the participants are prepared to receive treatment in another hospital if single-port surgery is not performed in their hometown hospital. The preference for single-port approach was higher in the female population. Although cure and safety remain the main concerns, the population and patients group have a favourable perception of single-port surgery. The impact of public opinion and patient perception towards innovative techniques is undeniable. If the safety of the two different procedures is similar, this study shows a positive attitude of both participant groups in favour of single-port laparoscopy. However, solid scientific proof for the safety and feasibility of this new surgical technique needs to be obtained

  2. Seismic evidence for hydration of the Central American slab: Guatemala through Costa Rica

    Syracuse, E. M.; Thurber, C. H.

    2011-12-01

    The Central American subduction zone exhibits a wide variability in along-arc slab hydration as indicated by geochemical studies. These studies generally show maximum slab contributions to magma beneath Nicaragua and minimum contributions beneath Costa Rica, while intermediate slab fluid contributions are found beneath El Salvador and Guatemala. Geophysical studies suggest strong slab serpentinization and fluid release beneath Nicaragua, and little serpentinization beneath Costa Rica, but the remainder of the subduction zone is poorly characterized seismically. To obtain an integrated seismic model for the Central American subduction zone, we combine 250,000 local seismic arrivals and 1,000,000 differential arrivals for 6,500 shallow and intermediate-depth earthquakes from the International Seismic Centre, the Central American Seismic Center, and the temporary PASSCAL TUCAN array. Using this dataset, we invert for Vp, Vs, and hypocenters using a variable-mesh double-difference tomography algorithm. By observing low-Vp areas within the normally high-Vp slab, we identify portions of the slab that are likely to contain serpentinized mantle, and thus contribute to higher degrees of melting and higher volatile components observable in arc lavas.

    Growing evidence suggests that sleep is important for procedural learning, but few studies have investigated the effect of sleep on the temporal aspects of motor skill learning. We assessed the effect of a 90-min day-time nap on learning a motor timing task, using 2 adaptations of a serial interception sequence learning (SISL) task. Forty-two right-handed participants performed the task before and after a 90-min period of sleep or wake. Electroencephalography (EEG) was recorded throughout. The motor task consisted of a sequential spatial pattern and was performed according to 2 different timing conditions, that is, either following a sequential or a random temporal pattern. The increase in accuracy was compared between groups using a mixed linear regression model. Within the sleep group, performance improvement was modeled based on sleep characteristics, including spindle- and slow-wave density. The sleep group, but not the wake group, showed improvement in the random temporal, but especially and significantly more strongly in the sequential temporal condition. None of the sleep characteristics predicted improvement on either general of the timing conditions. In conclusion, a daytime nap improves performance on a timing task. We show that performance on the task with a sequential timing sequence benefits more from sleep than motor timing. More important, the temporal sequence did not benefit initial learning, because differences arose only after an offline period and specifically when this period contained sleep. Sleep appears to aid in the extraction of regularities for optimal subsequent performance. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

  4. Lake Izabal (Guatemala) shoreline detection and inundated area estimation from ENVISAT ASAR images

    The surface extent of a lake reflects its water storage variations. This information has important hydrological and operational applications. However, there is a lack of information regarding this subject because the traditional methodologies for this purposes (ground surveys, aerial photos) requires high resources investments. Remote sensing techniques (optical/radar sensors) permit a low cost, constant and accurate monitoring of this parameter. The objective of this study was to determine the surface variations of Lake Izabal, the largest one in Guatemala. The lake is located close to the Caribbean Sea coastline. The climate in the region is predominantly cloudy and rainy, being the Synthetic Aperture Radar (SAR) the best suited sensor for this purpose. Although several studies have successfully used SAR products in detecting land-water boundaries, all of them highlighted some sensor limitations. These limitations are mainly caused by roughened water surfaces caused by strong winds which are frequent in Lake Izabal. The ESA's ASAR data products were used. From the set of 9 ASAR images used, all of them have wind-roughened ashore waters in several levels. Here, a chain of image processing steps were applied in order to extract a reliable shoreline. The shoreline detection is the key task for the surface estimation. After the shoreline extraction, the inundated area of the lake was estimated. In-situ lake level measurements were used for validation. The results showed good agreement between the inundated areas estimations and the lake level gauges.

    Full Text Available The U.S. is fast becoming more culturally diverse, creating a greater need for entry-level occupational therapists to be culturally competent. In order to increase students’ cultural competence, there is a growing support for international service learning (ISL. The purpose of this qualitative research study was to explore the perspectives of occupational therapy practitioners who engaged in ISL as occupational therapy students. Interviews were conducted with nine practicing occupational therapists, all of whom graduated from the same occupational therapy program in the U.S. and participated in an ISL experience in Guatemala. Phenomenological methods were used to analyze the transcribed interviews for codes, categories, and themes. The three themes that emerged were: Participants reported encountering many new experiences that led to experiencing a variety of emotions, their experiences in the Guatemalan culture further contributed to a deeper level of understanding about culture, and all of the participants reported that their ISL experiences allowed them to practice occupational therapy skills and interventions with limited resources, which facilitated creativity and resourcefulness. The findings of this study support that completing ISL as students contributes to occupational therapists’ personal and professional lives and offers a glimpse of potential long-term effects of completing an ISL experience.

    Full Text Available Abstract Small-scale studies on long-term change in agricultural knowledge might uncover insights with broader, regional implications. This article evaluates change in farmer knowledge about crop genetic resources in highland Guatemala between 1927/37 and 2004. It concentrates on maize (Zea mays ssp. mays L. in one Guatemalan township, Jacaltenango, an area with much ecological and maize diversity. It relies on a particular type of baseline information: lists of farmer-defined cultivars drawn up by ethnographers in the first half of the twentieth century. A questionnaire format based on two independent lists of local farmer cultivars dating from 1927 and 1937 was used to assess changes in maize diversity. Comparisons between attributes given to each cultivar in the past and in 2004 were used as a partial test of the stability of cultivar identity. In farmers' perceptions, cultivar loss was low and limited to certain cultivars adapted to the warmer environments. Crop production problems were mentioned as the main motives for change. No evidence for a loss of cultivars due to the political violence of the 1980s was found. In the lower areas many newly introduced cultivars were found, which reportedly provide solutions for the production problems the older cultivars have. The article contrasts these findings with those of an earlier study which suggested much cultivar loss due to political violence, and draws conclusions about the methodological implications.

    Full Text Available Abstract:International migration from rural areas affects the environment in numerous and complex ways. The inflow of economic and social remittances changes production and consumption patterns, social relations, and social and economic institutions in the places of origin of migrants. In this case study, I discuss how migration is pushing a local process of land redistribution in Guatemala. Such a process is also changing patterns of land use and land cover. The process is influenced by the emergence of local cooperatives, which in turn are stimulated by organizations and networks in wider temporal and spatial contexts. Land acquisition by migrant families has also improved their position vis-àvis traditional landowners. My study suggests that in contexts where local organization is successful and linked to actors and networks at wider scales, transnational households are in a good position to negotiate the outcomes of the use of remittances. These families are improving their living standards without degrading the environment irreversibly.Resumen: ('Con nuestro propio esfuerzo': Comprendiendo la relación entre la migración internacional y el medio ambiente en GuatemalaLa migración internacional de las zonas rurales afecta el medio ambiente de maneras significantes y complejas.

    2012-07-01

    This study presents findings of an institutional capacity analysis of urban disaster risk reduction for informal settlements in the Guatemala Metropolitan Region. It uses a resource access perspective of vulnerability, actor-network theory, and qualitative data collection. The analysis reveals that there is interest in disaster risk reduction for the informal settlements; however, there is little in the way of direct financial or oversight relationships between informal settlement residents and all other actors. Respondents observed that informal settlements would probably remain inhabited; thus, there is a need for disaster risk reduction within these settlements. Disaster risk reduction capacity for informal settlements exists and can be further leveraged, as long as steps are taken to ensure appropriate access to and control of resources and oversight. Further, the nascent institutional arrangements should be strengthened through increased communication and coordination between actors, a decentralization of oversight and financial relationships, and mediation of identified resource conflicts. © 2012 The Author(s).

    Two trapping systems were compared in a study in Guatemala during the wet season, May through Dec 2001. Trap/lure combinations consisting of green or yellow-based plastic McPhail-like traps baited with a synthetic 2-component lure (putrescine and ammonium acetate) and 300 mL of propylene glycol antifreeze as a preservative were compared to the traditional glass McPhail baited with torula yeast/borax and 300 mL of water. Both systems captured several key Anastrepha species including Anastrepha ludens Loew, A. obliqua, Macquart, A. serpentina Weidemann, A. striata Schiner, A. distincta Greene, A. fraterculus Weidemann as well as Ceratitis capitata Weidemann. Additionally, 13 other Anastrepha spp. were captured with the synthetic lure. The plastic traps captured more key flies than the McPhail trap except for A. distincta where there were no significant differences between the yellow-based plastic trap and the McPhail trap and no significant differences between any trap and lure for trapping A. fraterculus. The synthetic lure lasted 10 weeks. The sex ratio was female-biased for almost all captured key species in both systems. Moreover, there were significant numbers of captured nontarget insects in all traps; however, the captured flies in those traps with the synthetic lure were not adversely affected by these insects. Propylene glycol-based antifreeze was a superior preservative when compared to borax/water. (author) [es

    Strengthening health service delivery to the rural poor is an important means of redressing inequities. Meso-level managers can help enhance efficiency in the utilization of existing resources through the application of practical tools to analyze routinely collected data reflecting inputs and outputs. This study aimed to assess the efficiency and change in productivity of health posts over two years in a rural department of Guatemala. Data envelopment analysis was used to measure health posts' technical efficiency and productivity change for 2008 and 2009. Input/output data were collected from the regional health office of Alta Verapaz for 34 health posts from the 19 districts comprising the health region. Technical efficiency varied widely across health posts, with mean scores of 0.78 (SD=0.24) and 0.75 (SD=0.21) in 2008 and 2009, respectively. Overall, productivity increased by 4%, though 47% of health posts experienced a decline in productivity. Results were combined on a bivariate plot to identify health posts at the high and low extremes of efficiency, which should be followed up to determine how and why their production processes are operating differently. Assessing efficiency using the data that are available at the meso-level can serve as a first step in strengthening performance. Further work is required to support managers in the routine application of efficiency analysis and putting the results to use in guiding efforts to improve service delivery and increase utilization.

  11. Factors associated to acceptable treatment adherence among children with chronic kidney disease in Guatemala.

    Full Text Available Pediatric patients with Chronic Kidney Disease face several barriers to medication adherence that, if addressed, may improve clinical care outcomes. A cross sectional questionnaire was administered in the Foundation for Children with Kidney Disease (FUNDANIER, Guatemala City from September of 2015 to April of 2016 to identify the predisposing factors, enabling factors and need factors related to medication adherence. Sample size was calculated using simple random sampling with a confidence level of 95%, confidence interval of 0.05 and a proportion of 87%. A total of 103 participants responded to the questionnaire (calculated sample size was 96. Independent variables were defined and described, and the bivariate relationship to dependent variables was determined using Odds Ratio. Multivariate analysis was carried out using logistic regression. The mean adherence of study population was 78% (SD 0.08, max = 96%, min = 55%. The mean adherence in transplant patients was 82% (SD 7.8, max 96%, min 63%, and the mean adherence in dialysis patients was 76% (SD 7.8 max 90%, min 55%. Adherence was positively associated to the mother's educational level and to higher monthly household income. Together predisposing, enabling and need factors illustrate the complexities surrounding adherence in this pediatric CKD population. Public policy strategies aimed at improving access to comprehensive treatment regimens may facilitate treatment access, alleviating economic strain on caregivers and may improve adherence outcomes.

    2011-03-01

    The study described in this article incorporates stakeholders' views on aquatic invasion processes and combines expert analysis with information from field work into an evaluation exercise. Management scenarios are designed based on available technical data and stakeholders' perceptions. These scenarios are evaluated using the Social Multi-Criteria Evaluation framework employing the NAIADE model. Two evaluations are carried out, technical and social. Social acceptance of different management scenarios, distribution of costs and benefits, and attribution of responsibility are discussed. The case study was carried out on Lake Izabal, a body of water connected to the Caribbean Sea in Northeastern Guatemala. In 2000, local fishermen reported the presence of an alien species in the lake, the macrophyte Hydrilla verticillata. Two years later, this alien species was established around the entire lakeshore, damaging the ecosystem, endangering native species and the subsistence of local inhabitants through impacts on transportation, fishing practices, and tourism.

  15. Preliminary U-Th Dating of Endogenic Gypsum From Lake Petén-Itzá, Guatemala

    Uranium-thorium dating of lake sediments can provide accurate ages beyond the range of radiocarbon dating. Many lakes have endogenic precipitation of calcium bearing minerals that allow for substitution by uranium within their crystal structures. The water chemistry of Lake Petén-Itzá, located in northern Guatemala, is dominated by calcium, sulfate and carbonate ions (Deevey et al. 1980; Curtis et al. 1998). Changes in regional climate due to suspected shifts in the ITCZ over the past 85,000 years resulted in both calcite and gypsum deposition, especially during drier periods (Hodell et al. 2006). Both precipitates incorporate uranium from the lake water and can be used for U-Th dating. U-Th dating is problematic in lake systems for several reasons: the potential for 1) diagenetic alteration or dissolution while the endogenic precipitates are settling and after deposition and 2) contamination by detrital thorium. Contamination is a primary issue because of the difficulty of separating the precipitates from the sediment. Despite these concerns, U-Th dating of lake sediments has the potential to be successful with careful selection of precipitates and thorough analysis of the precipitate, the lake system, and the diagenetic environment. Preliminary samples of Lake Petén-Itzá gypsum contain euhedral crystals, indicating a lack of post-depositional alteration. However, the samples have high background thorium levels, indicating the necessity of using the U-Th total sample dissolution isochron dating method (as described by Ku, 2000) to quantify authigenic thorium.

    As the first large subduction thrust earthquake off the coast of western Guatemala in the past several decades, the 2012 November 7 Mw = 7.4 earthquake offers the first opportunity to study coseismic and postseismic behaviour along a segment of the Middle America trench where frictional coupling makes a transition from weak coupling off the coast of El Salvador to strong coupling in southern Mexico. We use measurements at 19 continuous GPS sites in Guatemala, El Salvador and Mexico to estimate the coseismic slip and postseismic deformation of the November 2012 Champerico (Guatemala) earthquake. An inversion of the coseismic offsets, which range up to ˜47 mm at the surface near the epicentre, indicates that up to ˜2 m of coseismic slip occurred on a ˜30 × 30 km rupture area between ˜10 and 30 km depth, which is near the global CMT centroid. The geodetic moment of 13 × 1019 N m and corresponding magnitude of 7.4 both agree well with independent seismological estimates. Transient postseismic deformation that was recorded at 11 GPS sites is attributable to a combination of fault afterslip and viscoelastic flow in the lower crust and/or mantle. Modelling of the viscoelastic deformation suggests that it constituted no more than ˜30 per cent of the short-term postseismic deformation. GPS observations that extend six months after the earthquake are well fit by a model in which most afterslip occurred at the same depth or directly downdip from the rupture zone and released energy equivalent to no more than ˜20 per cent of the coseismic moment. An independent seismological slip solution that features more highly concentrated coseismic slip than our own fits the GPS offsets well if its slip centroid is translated ˜50 km to the west to a position close to our slip centroid. The geodetic and seismologic slip solutions thus suggest bounds of 2-7 m for the peak slip along a region of the interface no larger than 30 × 30 km.

    An extreme rainfall event in October of 2005 triggered two deadly lahars on the flanks of Tolimán volcano (Guatemala) that caused many fatalities in the village of Panabaj. We mapped the deposits of these lahars, then developed computer simulations of the lahars using the geologic data and compared simulated area inundated by the flows to mapped area inundated. Computer simulation of the two lahars was dramatically improved after calibration with geological data. Specifically, detailed field measurements of flow inundation area, flow thickness, flow direction, and velocity estimates, collected after lahar emplacement, were used to calibrate the rheological input parameters for the models, including deposit volume, yield strength, sediment and water concentrations, and Manning roughness coefficients. Simulations of the two lahars, with volumes of 240,200 ± 55,400 and 126,000 ± 29,000 m3, using the FLO-2D computer program produced models of lahar runout within 3% of measured runouts and produced reasonable estimates of flow thickness and velocity along the lengths of the simulated flows. We compare areas inundated using the Jaccard fit, model sensitivity, and model precision metrics, all related to Bayes' theorem. These metrics show that false negatives (areas inundated by the observed lahar where not simulated) and false positives (areas not inundated by the observed lahar where inundation was simulated) are reduced using a model calibrated by rheology. The metrics offer a procedure for tuning model performance that will enhance model accuracy and make numerical models a more robust tool for natural hazard reduction.

    Santiaguito volcano, Guatemala, has been persistently active for decades, producing frequent explosions from its actively growing lava dome. Repeated release of volcanic gases contains information about conduit processes during the cyclical explosions at Santiaguito, but the composition of the gas phase and the amount of volatiles released in each explosion remains poorly constrained. In addition to its persistent activity, Santiaguito offers an exceptional opportunity to investigate lava dome degassing processes since the upper surface of the active lava dome can be viewed from the summit of neighboring Santa Maria. In January 2016 we conducted multi-spectral observations of Santiaguito's explosive eruption plumes and passive degassing from multiple perspectives as part of the first NSF-sponsored `Workshop on Volcanoes' instrument deployment. Gas measurements included open-path Fourier-Transform infrared (OP-FTIR) spectroscopy from the Santa Maria summit, coincident with ultraviolet (UV) and infrared (IR) camera and UV Differential Optical Absorption Spectroscopy (DOAS) from the El Mirador site below Santiaguito's active Caliente lava dome. Using the OP-FTIR in passive mode with the Caliente lava dome as the source of IR radiation, we were able to collect IR spectra at high temporal resolution prior to and during two explosions of Santiaguito on 7-8 January, with volcanic SO2 and H2O emissions detected. UV and IR camera data provide constraints on the total SO2 burden in the emissions (and potentially the volcanic ash burden), which coupled with the FTIR gas ratios provides new constraints on the mass and composition of volatiles driving explosions at Santiaguito. All gas measurements indicate significant volatile release during explosions with limited degassing during repose periods. In this presentation we will present ongoing analysis of the unique Santiaguito gas dataset including estimation of the total volatile mass released in explosions and an

    A case of favourable outcome of the treatment of extremely severe acute poisoning after prolonged exposure to lethal doses of methanol is reported. The complex treatment included urgent and effective elimination of the poison (multiple gastric lavage, hemodialysis), antidote therapy (administration of ethanol), correction of decompensated metabolic acidosis (alkali therapy and infusion therapy with reamberin). These measures had beneficial effect on the clinical course of poisoning and ensured its favourable outcome.

  1. The Value of Satellite Early Warning Systems in Kenya and Guatemala: Results and Lessons Learned from Contingent Valuation and Loss Avoidance Approaches

    Morrison, I.; Berenter, J. S.

    2017-12-01

    SERVIR, the joint USAID and NASA initiative, conducted two studies to assess the value of two distinctly different Early Warning Systems (EWS) in Guatemala and Kenya. Each study applied a unique method to asses EWS value. The evaluation team conducted a Contingent Valuation (CV) choice experiment to measure the value of a near-real time VIIRS and MODIS-based hot-spot mapping tool for forest management professionals targeting seasonal forest fires in Northern Guatemala. The team also conducted a survey-based Damage and Loss Avoidance (DaLA) exercise to calculate the monetary benefits of a MODIS-derived frost forecasting system for farmers in the tea-growing highlands of Kenya. This presentation compares and contrasts the use and utility of these two valuation approaches to assess EWS value. Although interest in these methods is growing, few empirical studies have applied them to benefit and value assessment for EWS. Furthermore, the application of CV and DaLA methods is much less common outside of the developed world. Empirical findings from these two studies indicated significant value for two substantially different beneficiary groups: natural resource management specialists and smallholder tea farmers. Additionally, the valuation processes generated secondary information that can help improve the format and delivery of both types of EWS outputs for user and beneficiary communities in Kenya and Guatemala. Based on lessons learned from the two studies, this presentation will also compare and contrast the methodological and logistical advantages, challenges, and limitations in applying the CV and DaLA methods in developing countries. By reviewing these two valuation methods alongside each other, the authors will outline conditions where they can be applied - individually or jointly - to other early warning systems and delivery contexts.

    Maternal and neonatal mortality figures remain unacceptably high worldwide and new approaches are required to address this problem. This paper evaluates the impact on maternal and neonatal mortality of a pregnancy care package for rural areas of developing countries with portable ultrasound and blood/urine tests. An observational study was conducted, with intervention and control groups not randomly assigned. Rural areas of the districts of Senahu, Campur and Carcha, in Alta Verapaz Department (Guatemala). The control group is composed by 747 pregnant women attended by the community facilitator, which is the common practice in rural Guatemala. The intervention group is composed by 762 pregnant women attended under the innovative Healthy Pregnancy project. That project strengthens the local prenatal care program, providing local nurses training, portable ultrasound equipment and blood and urine tests. The information of each pregnancy is registered in a medical exchange tool, and is later reviewed by a gynecology specialist to ensure a correct diagnosis and improve nurses training. No maternal deaths were reported within the intervention group, versus five cases in the control group. Regarding neonatal deaths, official data revealed a 64 % reduction for neonatal mortality. A 37 % prevalence of anemia was detected. Non-urgent referral was recommended to 70 pregnancies, being fetal malpresentation the main reported cause. Impact data on maternal mortality (reduction to zero) and neonatal mortality (NMR was reduced to 36 %) are encouraging, although we are aware of the limitations of the study related to possible biasing and the small sample size. The major reduction of maternal and neonatal mortality provides promising prospects for these low-cost diagnostic procedures, which allow to provide high quality prenatal care in isolated rural communities of developing countries. This research was not registered because it is an observational study where the assignment of

    The aim of this study was to contribute new data on autosomal STR and Y-STR markers of the Mayas from Guatemala in order to improve available databases of forensic interest. We analyzed 16 autosomal STR markers in a population sample of 155 indigenous Maya and 17 Y-chromosomal STR markers in the 100 males of the sample. Deviations from Hardy-Weinberg equilibrium and linkage disequilibrium between autosomal STR markers were not observed at any loci. The combined power of exclusion was estimated as 99.9991% and the combined power of discrimination was >99.999999999999%. Haplotype diversity of Y-STRs was calculated as 0.9984 ± 0.0018 and analysis of pairwise genetic distances (Rst) supported the Native American background of the population.

A agenda de pesquisa fundamenta-se historicamente nos legados da dominação colonial e da ditadura racial. A convergência de regra autoritária e discriminação racial resultou em atos deliberados de expropriação de terras comunais e forçou a remoção e o deslocamento de comunidades nativas. A erradicação de povoados inteiros, a migração de refugiados e a situação de populações transitórias acarretaram um notório abuso do Estado e o enriquecimento das elites. No entanto, o apoio da comunidade internacional à resolução do conflito e à reconciliação negligenciou a importância da terra para a estabilidade democrática e a paz social.This study compares how land disputes hampered conflict resolution and limited democratic citizenship in post-bellum Guatemala and post-apartheid South Africa. The research agenda is grounded historically in the legacies of colonial domination and racial dictatorship. The convergence of authoritarian rule and ethnic discrimination resulted in deliberate acts of dispossession of communal lands and forced removals and dislocation of indigenous communities. The uprooting of entire villages, and the migration of refugees, and the plight of transient populations entailed egregious state abuse and elite self-enrichment. Yet, the international community's support for conflict resolution and reconciliation neglected the significance of land for democratic stability and social peace.

    Measurements of length at birth, or in the neonatal period, are challenging to obtain and often discounted for lack of validity. Hence, classical 'under-5' stunting rates have been derived from surveys on children from 6 to 59 months of age. Guatemala has a high prevalence of stunting (49.8%), but the age of onset of growth failure is not clearly defined. The objective of the study was to assess length-for-age within the first 1.5 months of life among Guatemalan infants. As part of a cross-sectional observational study, supine length was measured in young infants. Mothers' height was measured. Length-for-age Z-scores (HAZ) were generated and stunting was defined as HAZ Guatemala. Three hundred and six newborns with a median age of 19 d. The median rural HAZ was -1.56 and prevalence of stunting was 38%; the respective urban values were -1.41 and 25%. Linear regression revealed no relationship between infant age and HAZ (r = 0.101, r(2) = 0.010, P = 0.077). Maternal height explained 3% of the variability in HAZ (r = 0.171, r(2) = 0.029, P = 0.003). Stunting must be carried over from in utero growth retardation in short-stature Guatemalan mothers. As linear growth failure in this setting begins in utero, its prevention must be linked to maternal care strategies during gestation, or even before. A focus on maternal nutrition and health in an intergenerational dimension is needed to reduce its prevalence.

    Full Text Available This article deals with the International Commission against Impunity in Guatemala (CICIG, a joint hybrid commission to investigate impunity in the context of illegal security networks and organized crime. It was set up as an external governance intervention through an agreement between the UN and the State of Guatemala in 2006 to strengthen state institutions in the face of a worsening security situation. Based on a delegation of governance in the modality of shared sovereignty, CICIG has been operating in the country since 2006, trying to generate support in the national realm and the judicial system of Guatemala while exposed to the critical junctures of the highly contested national debates on its existence. More specifically, the article analyses the patterns of appropriation and rejection of CICIG by different actor constellations. Through a critical discourse analysis, actor constellations are specified, various themes of appropriation and rejection are detected and specific aspects of CICIG’s mandate are investigated. Resumen: ¿Intervención por invitación?

    Understanding the trans-boundary deforestation history and patterns in protected areas along the Belize-Guatemala border is of regional and global importance. To assess deforestation history and patterns in our study area along a section of the Belize-Guatemala border, we incorporated multi-temporal deforestation rate analysis and spatial metrics with survey results. This multi-faceted approach provides spatial analysis with relevant insights from local stakeholders to better understand historic deforestation dynamics, spatial characteristics and human perspectives regarding the underlying causes thereof. During the study period 1991-2014, forest cover declined in Belize's protected areas: Vaca Forest Reserve 97.88%-87.62%, Chiquibul National Park 99.36%-92.12%, Caracol Archeological Reserve 99.47%-78.10% and Colombia River Forest Reserve 89.22%-78.38% respectively. A comparison of deforestation rates and spatial metrics indices indicated that between time periods 1991-1995 and 2012-2014 deforestation and fragmentation increased in protected areas. The major underlying causes, drivers, impacts, and barriers to bi-national collaboration and solutions of deforestation along the Belize-Guatemala border were identified by community leaders and stakeholders. The Mann-Whitney U test identified significant differences between leaders and stakeholders regarding the ranking of challenges faced by management organizations in the Maya Mountain Massif, except for the lack of assessment and quantification of deforestation (LD, SH: 18.67, 23.25, U = 148, p > 0.05). The survey results indicated that failure to integrate buffer communities, coordinate among managing organizations and establish strong bi-national collaboration has resulted in continued ecological and environmental degradation. The information provided by this research should aid managing organizations in their continued aim to implement effective deforestation mitigation strategies. Copyright © 2016 Elsevier

  20. Subverting Justice: Socio-Legal Determinants of Impunity for Violence against Women in Guatemala

    Directory of Open Access Journals (Sweden)

    Cecilia Menjívar

    2016-07-01

    Full Text Available High levels of violence against women and impunity in Guatemala have reached crisis proportions and have received increased international attention in recent years. The phenomenon of feminicide (e.g., killings of women in the context of state impunity, is widespread in Latin America and particularly acute in Guatemala. Many (if not the majority are rooted in violence that becomes concentrated in the family. In this paper, we propose that both the structure and application of the laws in Guatemala contribute to widespread impunity. Police and judges use laws other than those created to address violence against women in order to justify lack of enforcement. For example, judges resist issuing restraining orders, and police refuse to apply them because this can violate perpetrators’ property rights. Judges also refuse to apply domestic violence laws because this violates the principle of equality under the law. Women refuse to use the legal system to seek justice because alimony laws will not be enforced and women are economically dependent. The discriminatory fashion in which these laws are applied leads to widespread impunity. Even though laws on the books could be applied otherwise, those who implement them privilege laws that conflict with violence against women laws. While much scholarship focuses on individual-level motives for violence, we instead analyze the socio-legal environment and existing legal codes that enable continued failure to respond adequately to violence against women. The legal framework and the legal code itself are deeply shaped by the context in which they are written—the structural, gender, symbolic, everyday and long arm of political violence that permeate all aspects of life in Guatemala and exacerbate women’s vulnerability, especially the poor. We argue that this broader legal context endangers the lives of women in Guatemala. We also extend the socio-legal scholarship to highlight failures for victim

  1. Current role and future developments of radiotherapy in early-stage favourable Hodgkin's lymphoma

    The radiosensibility of Hodgkin's lymphoma (HL) is well established since 1902, when Pusey was one of the first to publish about radiotherapeutical treatment of a HL. In the early years, radiotherapy was the only curative treatment for this systemic disease, but the reports of Kaplan and Rosenberg and Peters in the fifties and seventies showed that irradiation of involved lymph node regions only resulted in high local and distant recurrences. The introduction of linear accelerator based high dose extended field (EF)-radiotherapy by Kaplan in Stanford was a milestone in the evolution of definitive curative radiotherapy strategies. The application of the mantle field for supradiaphragmatic and the inverted Y (with or without including the spleen or splenic pedicle) for infradiaphragmatic disease resulted in a dramatic improvement of survival rates in the early stages I and II (Ann Arbor) from 25-30% in the sixties to 65-80% in the eighties. Kaplan reported about a close relationship between radiation dose and cure rates in the case of definitive radiotherapy. A dose of at least 40 Gy resulted in local recurrences below 5% and is today the standard dose for radiotherapy only outside protocols. Despite complete remission rates after radiotherapy of 90-100%, the overall recurrence rate (including in-field, marginal and distant relapses) was between 20 and 30%. Analysis of the relapses revealed some stage migrating risk factors: large mediastinal mass, extra nodal involvement, number of involved lymph node areas (≥ 3) and high ESR. The possibility of more accurate staging by using new imaging techniques like ultrasonography, CT and MRI as well as PET in the recent years resulted e.g. in the definition of early-favourable, early-unfavourable (intermediate) and high risk stages and more specific, risk adapted treatment strategies. The objective of this article is to show recent achievements and developments in the management of early-stage favourable HL exemplified by

    In Central America, most Maya women use ethnomedicines for all aspects of their reproductive cycle including menstruation, pregnancy and menopause. However, very few of these plants have been documented, collected and tested in appropriate pharmacological assays to determine possible safety and efficacy. The aim of this work was to provide an overview of information on the ethnomedical uses, ethnopharmacology, chemistry and pharmacological research for medicinal plants used for women's reproductive health in Guatemala, with a special emphasis on the Q'eqchi Maya of the Lake Izabal region, to demonstrate therapeutic potential and support future research in the field. Reviews of the ethnobotanical, ethnomedical and ethnopharmacological literature were performed for 30 plants collected in the Lake Izabal region of Guatemala and used by the Q'eqchi Maya for treatment of reproductive health issues were performed up to and including July 2015 using multiple databases, library searches for abstracts, books, dissertations, and websites. Review of the published research confirms that many of the plants used by Q'eqchi Maya women for the management of reproductive health issues have pharmacological activities, including analgesic, anti-inflammatory, estrogenic, progestagenic and/or serotonergic effects, that support the use of these plants and provide plausible mechanisms of action for their traditional uses. Furthermore, a new serotonin agonist, 9, 10-methylenedioxy-5, 6-Z-fadyenolide was isolated, thereby demonstrating an untapped potential for drug discovery. However, to date much of the pharmacological assays have been in vitro only, and few in vivo studies have been performed. Considering the large percentage of the Maya population in Guatemala that use traditional medicines, there remains a significant lack of pharmacological and toxicological data for these plants. Future research should focus on the safety and efficacy of medicinal plants using in vivo preclinical

    When associated with high blood pressure, type 2 diabetes mellitus is characterised by a high risk of adverse cardiovascular (CV) and renal outcomes. However, both can be effectively reduced by antihypertensive treatment. Current guidelines on the treatment of hypertension emphasize the need to effectively treat high blood pressure in diabetic individuals, but their recommendations differ in terms of the optimal target blood pressure value to aim for in order to maximise CV and renal protection. In some guidelines the recommended target blood pressure values are blood pressure values close or even less than 130/80 mmHg are recommended. This paper will discuss the evidence for and against a conservative or more aggressive blood pressure target for treated diabetic hypertensive individuals based on the evidence provided by randomised trials, trial meta-analyses and large observational studies. Based on the available evidence, it appears that blood pressure targets will probably have to be lower than <140/90 mmHg, and that values approaching 130/80 mmHg should be recommended. However, evidence in favour of even lower systolic values, i.e. <130 mmHg, is limited and is definitively against a reduction to <120 mmHg.

    Full Text Available Climate factors that are proposed to determine agriculturally less favoured areas (LFA in Slovenia were analyzed for the period 1981–2010. Following the instructions of European Commission prepared by Joint Research Centre (JRC 30-years averages of low air temperatures criteria (the vegetation period duration and sums of effective air temperatures and aridity criteria (aridity index AI have to be calculated. Calculations were additionally done using Slovenian Environment Agency (ARSO method, which is slightly different when determining temperature thresholds. Only hilly areas are below the LFA low air temperatures threshold with the lowest located meteorological station in Rateče. According to aridity criteria no area in Slovenia is below the threshold, so meteorological water balance was also examined. Average water balance in the period 1981–2010 was in most of locations lower than in the period 1971–2000. Climate change impacts are already expressed as trend presence in time series of studied variables, so it is recommended to calculate trends and take them into account or to perform regular iterations of calculations.

  7. Living with strangers: direct benefits favour non-kin cooperation in a communally nesting bird.

    The greater ani (Crotophaga major), a Neotropical cuckoo, exhibits an unusual breeding system in which several socially monogamous pairs lay eggs in a single nest and contribute care to the communal clutch. Cooperative nesting is costly-females compete for reproduction by ejecting each other's eggs-but the potential direct or indirect fitness benefits that might accrue to group members have not been identified. In this study, I used molecular genotyping to quantify patterns of genetic relatedness and individual reproductive success within social groups in a single colour-banded population. Microsatellite analysis of 122 individuals in 49 groups revealed that group members are not genetic relatives. Group size was strongly correlated with individual reproductive success: solitary pairs were extremely rare and never successful, and nests attended by two pairs were significantly more likely to be depredated than were nests attended by three pairs. Egg loss, a consequence of reproductive competition, was greater in large groups and disproportionately affected females that initiated laying. However, early-laying females compensated for egg losses by laying larger clutches, and female group members switched positions in the laying order across nesting attempts. The greater ani, therefore, appears to be one of the few species in which cooperative breeding among unrelated individuals is favoured by direct, shared benefits that outweigh the substantial costs of reproductive competition.

    Progesterone (P 4 ) levels in skin milk were determined in two groups of dual purpose cows from farms in the Department of Escuintla on the south coast of Guatemala. Fifteen adult cows (crosses of Criollo with Zebu and Brown Swiss) were selected on the first farm and ten first-calf heifers (crosses of Criollo with Zebu and Holstein) on the second; both groups were considered to be representative of dual purpose livestock (milk and meat producers) in the country. To study the resumption of ovarian activity post-partum, milk samples were taken once a week from 10 days after calving until the first natural service; thereafter, sampling continued twice-weekly for 60 more days when the animals were rectally palpated for pregnancy diagnosis. On farm 1, the mean interval from calving to first rise in P 4 levels indicative of ovarian function was 42±16.7 days; all the study cows were at third calving and resumed cyclicity. On farm 2, only 30% of the study heifers resumed cyclicity and these had an interval from calving to first rise in P 4 of 80±28.9 days; all were at first calving. On farm 1, 73% of cows were served during first oestrus, 13% at second oestrus and 13% at the third. On farm 2, only 30% (3/10) of cows were served at first oestrus; the other 70% did not show signs of ovarian activity during the trial period which lasted until day 129 post-partum. Palpation of the cows 60 days post-service showed that all cows had conceived on farm 1 but only 20% on farm 2. (author). 9 refs, 3 figs

    Treatment refusal and abandonment are major causes of treatment failure for children with cancer in low- and middle-income countries (LMICs), like Guatemala. This study identified risk factors for and described the intervention that decreased abandonment. This was a retrospective study of Guatemalan children (0-18 years) with cancer treated at the Unidad Nacional de Oncología Pediátrica (UNOP), 2001-2008, using the Pediatric Oncology Network Database. Treatment refusal was a failure to begin treatment and treatment abandonment was a lapse of 4 weeks or longer in treatment. The impact of medicina integral, a multidisciplinary psychosocial intervention team at UNOP was evaluated. Cox proportional hazards analysis identified the effect of demographic and clinical factors on abandonment. Kaplan-Meier analysis estimated the survival. Of 1,789 patients, 21% refused or abandoned treatment. Abandonment decreased from 27% in 2001 to 7% in 2008 following the implementation of medicina integral. Factors associated with increased risk of refusal and abandonment: greater distance to the centre (P < 0.001), younger age (P = 0.017) and earlier year of diagnosis (P < 0.001). Indigenous race/ethnicity (P = 0.002) was associated with increased risk of abandonment alone. Abandonment correlated with decreased overall survival: 0.57 ± 0.02 (survival ± standard error) for those who completed therapy versus 0.06 ± 0.02 for those who abandoned treatment (P < 0.001) at 8.3 years. This study identified distance, age, year of diagnosis and indigenous race/ethnicity as risk factors for abandonment. A multidisciplinary intervention reduced abandonment and can be replicated in other LMICs. © 2017 Wiley Periodicals, Inc.

    This article analyses the relation between mining conflicts, development, and processes of democratic participation in Guatemala. Through a case study in the municipality of San Idelfonso Ixtahuacán in the department of Huehuetenango, the article explores how cases of activism can be understood in relation to experiences of citizenship in Guatemala. The article firstly tells the story of the march of the miners of Ixtahuacán and how this march can be understood in the context of the internal armed conflict (1960–1996. Secondly, it explores how the armed conflict shapes the contemporary ways in which the population resists mining and how the Guatemalan state reacts to these protest actions.

    Paraneoplastic pemphigus (PNP) is an autoimmune blistering disorder that occurs in association with an underlying neoplasm. Inflammatory myofibroblastic tumour (IMT) is a rare low-grade sarcoma of fibroblasts and myofibroblasts associated with inflammatory cells, most commonly occurring in the lung. In this study, a case of PNP associated with IMT of the mediastinum is reported. The patient had a favourable outcome following surgical resection and treatment with a systemic steroid, azathioprine, and i.v. immunoglobulin. The occurrence of PNP with sarcomas, specifically IMT, is noteworthy although it is not well studied in the existing literature. © 2014 The Australasian College of Dermatologists.

    The anisotropy in favoured alpha transitions which produce even-even deformed nuclei is discussed. A simple, Gamow's-like model which takes into account the quadrupole deformation of the product nucleus has been formulated to calculate the alpha decay half-life. It is assumed that before tunneling into a purely Coulomb potential barrier the two-body system oscillated isotropically, thus giving rise to an equivalent, average preferential polar direction θ 0 (referred to the symmetry axis of the ellipsoidal shape of the product nucleus) for alpha emission in favoured alpha transitions of even-even nuclei.

  15. Holocene climate variability and anthropogenic impacts from Lago Paixban, a perennial wetland in Peten, Guatemala

    Analyses of an ~ 6 m sediment core from Lago Paixban in Peten, Guatemala, document the complex evolution of a perennial wetland over the last 10,300 years. The basal sediment is comprised of alluvial/colluvial fill deposited in the early Holocene. The absence of pollen and gastropods in the basal sediments suggests intermittently dry conditions until ~ 9000 cal yr. BP (henceforth BP) when the basin began to hold water perennially. Lowland tropical forest taxa dominated the local vegetation at this time. A distinct band of carbonate dating to ~ 8200 BP suggests regionally dry conditions, possibly associated with the 8.2 ka event. Wetter conditions during the Holocene Thermal Maximum are indicated by evidence of a raised water level and an open water lake. The timing of this interval coincides with strengthening of the Central American Monsoon. An abrupt change at 5500 BP involved the development of a sawgrass marsh and onset of peat deposition. The lowest recorded water levels date to 5500–4500 BP. Pollen, isotope, geochemical, and sedimentological data indicate that the coring site was near the edge of the marsh during this period. A rise in the water table after 4500 BP persisted until around 3500 BP. Clay marl deposition from 3500 to 210 BP corresponds to the period of Maya settlement. An increase in δ13C, the presence of Zea pollen, and a reduction in the percentage of forest taxa pollen indicate agricultural activity at this time. In contrast to several nearby paleoenvironmental studies, proxy evidence from Lago Paixban indicates human presence through the Classic/Postclassic period transition (~ 1000 BP) and persisting until the arrival of Europeans. Cessation of human activity around 210 BP resulted in local afforestation and the re-establishment of the current sawgrass marsh at Lago Paixban.

    Chagas disease results in the largest burden, in terms of disability-adjusted-life-years, of any parasitic disease in the Americas. Monitoring Chagas disease among migrants is critical to controlling its spread and to serving the needs of the migrant community. Therefore, we determined the prevalence and correlates of Chagas disease in regional and international migrant populations at the Mexico/Guatemala border. Data were collected as part of a larger study of human immunodeficiency virus (HIV) and migration. Participants were a sample of recent regional and international migrants who used an illicit substance or had recent problem drinking. Trypanosoma cruzi infection was classified as testing positive on two different enzyme-linked immunosorbent assays (ELISAs). Interviewer-administered surveys captured sociodemographics, migration history, Chagas disease knowledge, and access to care. We enrolled 389 recent migrants, and the prevalence of Chagas disease was 3.1%. Only 19% of the participants reported having ever heard of the disease and less than 1% had been previously tested. Trypanosoma cruzi -positive participants were more likely to have been born in a rural area or town than a city (92% yes versus 59% no, P = 0.02) and have recently lived in a house with a makeshift roof (33% yes versus 8% no, P < 0.01), walls (42% yes versus 13% no, P < 0.01), or floor (50% yes versus 21% no, P < 0.02), or cinderblock walls (92% yes versus 63% no, P = 0.04). With migration rapidly changing the distribution of Chagas disease, more work needs to be done to create targeted surveillance programs and provide access to affordable treatment among Latin American migrants.

    Analyses of an 6 m sediment core from Lago Paixban in Peten, Guatemala, document the complex evolution of a perennial wetland over the last 10,300 years. The basal sediment is comprised of alluvial/colluvial fill deposited in the early Holocene. The absence of pollen and gastropods in the basal sediments suggests intermittently dry conditions until 9000 cal yr. BP (henceforth BP) when the basin began to hold water perennially. Lowland tropical forest taxa dominated the local vegetation at this time. A distinct band of carbonate dating to 8200 BP suggests regionally dry conditions, possibly associated with the 8.2 ka event. Wetter conditions during the Holocene Thermal Maximum are indicated by evidence of a raised water level and an open water lake. The timing of this interval coincides with strengthening of the Central American Monsoon. An abrupt change at 5500 BP involved the development of a sawgrass marsh and onset of peat deposition. The lowest recorded water levels date to 5500-4500 BP. Pollen, isotope, geochemical, and sedimentological data indicate that the coring site was near the edge of the marsh during this period. A rise in the water table after 4500 BP persisted until around 3500 BP. Clay marl deposition from 3500 to 210 BP corresponds to the period of Maya settlement. An increase in δ13C, the presence of Zea pollen, and a reduction in the percentage of forest taxa pollen indicate agricultural activity at this time. In contrast to several nearby paleoenvironmental studies, proxy evidence from Lago Paixban indicates human presence through the Classic/Postclassic period transition ( 1000 BP) and persisting until the arrival of Europeans. Cessation of human activity around 210 BP resulted in local afforestation and the re-establishment of the current sawgrass marsh at Lago Paixban.

    There is a lack of knowledge regarding the composition, production, distribution, and consumption of artisanal alcohol, particularly in the developing world. In Nahuala, an indigenous Mayan municipality located in highland Guatemala, heavy alcohol consumption appears to have had a significant negative impact on health, a major role in cases of violence and domestic abuse, and a link to street habitation. Cuxa, an artisanally, as well as commercially produced sugarcane alcohol, is widely consumed by heavy drinkers in this community. Cuxa samples from all distribution points in the community were obtained and chemically analyzed for health-relevant constituents and contaminants including methanol, acetaldehyde, higher alcohols, and metals. From those, only acetaldehyde was confirmed to be present in unusually high levels (up to 126 g/hl of pure alcohol), particularly in samples that were produced clandestinely. Acetaldehyde has been evaluated as 'possibly carcinogenic' and has also been identified as having significant human exposure in a recent risk assessment. This study explores the reasons for the elevated levels of acetaldehyde, through both sampling and analyses of raw and intermediary products of cuxa production, as well as interviews from producers of the clandestine alcohol. For further insight, we experimentally produced this alcohol in our laboratory, based on the directions provided by the producers, as well as materials from the town itself. Based on these data, the origin of the acetaldehyde contamination appears to be due to chemical changes induced during processing, with the major causative factors consisting of poor hygiene, aerobic working conditions, and inadequate yeast strains, compounded by flawed distillation methodology that neglects separation of the first fractions of the distillate. These results indicate a preventable public health concern for consumers, which can be overcome through education about good manufacturing practices, as well

    Two trapping systems were compared in a study in Guatemala during the wet season, May through Dec 2001. Trap/lure combinations consisting of green or yellow-based plastic McPhail-like traps baited with a synthetic 2-component lure (putrescine and ammonium acetate) and 300 mL of propylene glycol antifreeze as a preservative were compared to the traditional glass McPhail baited with torula yeast/borax and 300 mL of water. Both systems captured several key Anastrepha species including Anastrepha ludens Loew, A. obliqua, Macquart, A. serpentina Weidemann, A. striata Schiner, A. distincta Greene, A. fraterculus Weidemann as well as Ceratitis capitata Weidemann. Additionally, 13 other Anastrepha spp. were captured with the synthetic lure. The plastic traps captured more key flies than the McPhail trap except for A. distincta where there were no significant differences between the yellow-based plastic trap and the McPhail trap and no significant differences between any trap and lure for trapping A. fraterculus. The synthetic lure lasted 10 weeks. The sex ratio was female-biased for almost all captured key species in both systems. Moreover, there were significant numbers of captured nontarget insects in all traps; however, the captured flies in those traps with the synthetic lure were not adversely affected by these insects. Propylene glycol-based antifreeze was a superior preservative when compared to borax/water.

  1. Reconstructed Ancestral Enzymes Impose a Fitness Cost upon Modern Bacteria Despite Exhibiting Favourable Biochemical Properties.

    Ancestral sequence reconstruction has been widely used to study historical enzyme evolution, both from biochemical and cellular perspectives. Two properties of reconstructed ancestral proteins/enzymes are commonly reported--high thermostability and high catalytic activity--compared with their contemporaries. Increased protein stability is associated with lower aggregation rates, higher soluble protein abundance and a greater capacity to evolve, and therefore, these proteins could be considered "superior" to their contemporary counterparts. In this study, we investigate the relationship between the favourable in vitro biochemical properties of reconstructed ancestral enzymes and the organismal fitness they confer in vivo. We have previously reconstructed several ancestors of the enzyme LeuB, which is essential for leucine biosynthesis. Our initial fitness experiments revealed that overexpression of ANC4, a reconstructed LeuB that exhibits high stability and activity, was only able to partially rescue the growth of a ΔleuB strain, and that a strain complemented with this enzyme was outcompeted by strains carrying one of its descendants. When we expanded our study to include five reconstructed LeuBs and one contemporary, we found that neither in vitro protein stability nor the catalytic rate was correlated with fitness. Instead, fitness showed a strong, negative correlation with estimated evolutionary age (based on phylogenetic relationships). Our findings suggest that, for reconstructed ancestral enzymes, superior in vitro properties do not translate into organismal fitness in vivo. The molecular basis of the relationship between fitness and the inferred age of ancestral LeuB enzymes is unknown, but may be related to the reconstruction process. We also hypothesise that the ancestral enzymes may be incompatible with the other, contemporary enzymes of the metabolic network.

  2. October 2005 Debris Flows at Panabaj, Guatemala:Hazard Assessment

    2007-05-01

    In October, 2005, tropical storm Stan caused heavy precipitation throughout much of Guatemala. In the community of Panabaj, Santiago Atitlán, a landslide of pyroclastic material originating high on the slopes of Tolimán volcano buried much of the community, leaving approximately 400 people dead. Current estimates by the Coordinadora Nacional para la Reducción de Desastres (CONRED) suggest that at least 2,600 people from the community of Panabaj, Santiago Atitlán have been displaced by the debris flows. Because the temporary housing for people displaced by the debris flows is located in an area that is geologically and morphologically similar to the area inundated by flows in October, 2005, this area may be potentially inundated by debris flows as well. In addition to the thousands of people living in temporary shelters, many hundreds of people are currently reoccupying land adjacent to or on the October, 2005 debris flows. Thus a large fraction of the surviving Panabaj community appears to remain at risk from future debris flows. We used differential GPS (Global Positioning System) to outline the boundaries of the debris flows, to estimate variation in flow thicknesses, and to determine their volumes. Mass movement on Tolimán volcano resulted in the generation of a moderate size debris flow (360,000 m3 of sediment plus water) that descended the volcano rapidly, bifurcated into two stream valleys high on the flanks of the volcano, and continued to descend both channels until these flows reached the alluvial fan near the shores of Lago de Atitlán. After bifurcating into two flows high on the flanks of the volcano, about 65% of the flow (by volume) descended the western channel, forming the Western flow. Approximately one kilometer above the alluvial fan, this channel descends steep topography, with a slope of 11.5°. This average slope gradually decreases down the channel, reaching only 5.3° just above the alluvial fan. In contrast, average slopes on the

    Migration necessarily precedes environmental change in the form of deforestation and soil degradation in tropical settlement frontiers. But what environmental factors may contribute to these migration streams in the first place? Identification of the environmental characteristics related to this process is crucial for understanding how environmental change and migration may form recurrent feedback loops. Further understanding of this process could be useful for developing policies to both reduce environmentally induced migration from origin areas and also palliate significant environmental change unleashed by settler deforestation in destination areas. Evidently, apprehension of this holistic process cannot be approached only from the destination since this ignores environmental and other antecedents to rural out-migration. This letter presents data from surveys conducted in areas of high out-migration to the agricultural frontier in northern Guatemala. The results suggest that land scarcity and degradation in origin communities are linked to out-migration in general and to the forest frontier of northern Guatemala in particular. (letter)

This song tradition of Santiago Atitlán, Guatemala is slowly disappearing as the socio-cultural context in which it flourished changes. By comparing the poetics of the song texts (including their rhythmic structure, versification, and use of poetic devices such as assonance, alliteration and onomatopoeia to the poetics of the Popol Vuh, a K’iché Maya text probably copied from a manuscript that predates the Spanish invasion, a continuity is discovered that places the song texts squarely within the tradition of Mayan literature and suggests common origins.

  11. Circulating Irisin Concentrations Are Associated with a Favourable Lipid Profile in the General Population.

    Directory of Open Access Journals (Sweden)

    Simon Oelmann

    Full Text Available Irisin is a myokine, which is mainly inversely associated with the risk for non-communicable diseases. Irisin improves cellular energy metabolism by uncoupling the mitochondrial respiratory chain resulting in increased energy expenditure using lipids. To date potential associations between irisin concentration and lipid profile are poorly understood. Therefore, this investigation aimed to evaluate potential associations between irisin and lipid levels in the general population.Data of 430 men and 537 women from the population-based Study of Health in Pomerania (SHIP-TREND with available irisin and lipid concentrations were used. Analyses of variance, linear and logistic regression models adjusted for age, HBA1c, waist circumference, physical activity, smoking, alcohol consumption, systolic blood pressure, ALAT were calculated.We detected significantly inverse associations between irisin and circulating levels of total [beta coefficient 0.21 (standard error 0.08, p = 0.01], low-density cholesterol [-0.16 (0.07, p = 0.03] and triglycerides [-0.17 (0.08, p = 0.02] for men. Females without lipid lowering medication had an inverse association between irisin and total cholesterol [-0.12 (0.06, p = 0.05]. Further, male subjects with irisin concentrations in the third tertile had an increased odds for elevated low-density cholesterol [odds ratio 1.96 (95% confidence interval 1.07-3.48, p = 0.03 and triglyceride [1.95 (1.09-3.47, p = 0.02] levels, even after exclusion of subjects with lipid lowering medication. In addition, our data revealed an annual rhythm of serum irisin levels with peak levels arise in winter and summer months.This is the first investigation to report a significant association between circulating irisin and a favourable lipid profile in the general population. This may infer that higher irisin concentrations are associated with a reduced risk for non-communicable diseases.

    This paper discusses the development Mayan linguistics as an authoritative field of knowledge in Guatemala. In particular, it links missionary linguists' and Maya linguists' activities with shifting nationalist agendas from the 1920s in to the late 1980s. It is argued that during the historical and intellectual moment that linguistics becomes an authoritative epistemology, phonetic analysis functions as a creative index that constitutes "expert" knowledge for particular semiotic and ideological reasons tied to competing versions of the Guatemalan imagined community.

    Despite recommendations that women give birth with a skilled birth attendant (SBA), 70% of births in Guatemala occur outside health facilities with informally trained traditional birth attendants (TBAs). To increase SBA in rural, indigenous communities, a professional midwifery school accredited by the government is scheduled to open in 2017. Drawing from Filby's model on barriers to the successful integration of professional midwifery into health systems, this paper aims to identify threats - and facilitators-toward professional midwifery's re-introduction in Guatemala. To elucidate perceptions, attitudes and expectations towards professional midwifery, qualitative, in-depth interviews were conducted with 32 physicians, nurses, and TBAs in six health centers and with key decision makers and professional midwives (PMs) in Guatemala City. We conducted open and axial coding in Atlas.ti and performed normative comparisons of participants' attitudes, perceptions, and expectations with the National Vision for professional midwifery and relative comparisons within and across disciplinary subgroups. Unprompted, physicians, nurses and TBAs were unable to correctly define professional midwifery. Yet, when professional midwifery was defined for them, they expressed willingness to work with PMs, seeing them as a needed human resource, instrumental in providing intercultural care and strengthening facility relationships with TBAs. Some stakeholders anticipated resistance toward PMs due to provider turf issues. Notable differences in expectations among all groups included ideas for supervision of and by the PMs and the PM's role in monitoring women and conducting births in communities alongside TBAs. Facilitators to professional midwifery's success include national political will, stakeholders' uniformity of vision, and the potential for improved intercultural care. Barriers are mostly professional in nature, including impediments to autonomous practice by PMs, hierarchical

    To estimate the number of new cases of cleft lip and cleft palate in the department (state) of Alta Verapaz, Guatemala, in 2012. Cross-sectional survey of midwives from communities identified through a two-stage cluster-sampling process. Midwives were asked how many babies they had delivered in the past year and how many of those newborns had various types of birth defects, as illustrated in pictures. Indigenous Mayan communities in rural north-central Guatemala. Midwives (n = 129) who had delivered babies in the previous year. Reports of babies born with cleft lip and cleft palate. A 1-year prevalence rate of 18.9 per 10,000 for cleft lip and 4.7 per 10,000 for cleft palate was estimated for Alta Verapaz. None of the cases of cleft lip also had cleft palate. The indigenous communities in north-central Guatemala might have a relatively high cleft lip prevalence rate compared with the global average.

    Over 5% of the world's population has varying degrees of hearing loss. Mutations in GJB2 are the most common cause of autosomal recessive non-syndromic hearing loss (ARNHL) in many populations. The frequency and type of mutations are influenced by ethnicity. Guatemala is a multi-ethnic country with four major populations: Maya, Ladino, Xinca, and Garifuna. To determine the mutation profile of GJB2 in a ARNHL population from Guatemala, we sequenced both exons of GJB2 in 133 unrelated families. A total of six pathogenic variants were detected. The most frequent pathogenic variant is c.131G>A (p.Trp44*) detected in 21 of 266 alleles. We show that c.131G>A is associated with a conserved haplotype in Guatemala suggesting a single founder. The majority of Mayan population lives in the west region of the country from where all c.131G>A carriers originated. Further analysis of genome-wide variation of individuals carrying the c.131G>A mutation compared with those of Native American, European, and African populations shows a close match with the Mayan population. © 2015 John Wiley & Sons A/S.

    To explore the use of rapid needs assessment (RNA) surveys to determine the prevalence and factors contributing to delays in vaccination of children in two low middle-income countries (LMIC). Data from two RNA surveys performed as part of program improvement evaluations in Guatemala and Peru were used for this analysis. The primary endpoint was the timeliness of immunization with delay defined as administration of vaccines beyond 28 days from recommended age for DTwP-HepB-Hib (Penta) and measles-mumps-rubella (MMR) vaccines, as well as past age-restrictions for rotavirus vaccine. Independent risk factors analyzed included child's gender, birth year, number of children in household, maternal age, maternal education, and food insecurity. Vaccine information was available from 811 children from 838 households surveyed. High rate of immunization delays was observed, with 75.6% of children in Guatemala and 57.8% of children in Peru being delayed for the third dose of Penta primary series. Factors associated with delayed vaccination in Guatemala included advanced maternal age and increased number of children in household. In Peru, significant associations were birth year before 2009, lower maternal education level, and increased number of children in household. RNA is a fast and effective method to identify timely vaccine coverage and derive a hypothesis of factors possibly associated with vaccination delay. Copyright © 2016 Elsevier Ltd.

    The Chronic Disease Research Fellowship Program (RFP) aims to build the research capacity of recent medical graduates to support the development of chronic disease control strategies. Guatemala is undergoing an epidemiologic transition. However, given the way universities and the health care system are structured, it lacks an environment that fosters research careers and generates the required knowledge to implement sound public health policies and clinical strategies. The RFP was implemented at the Cardiovascular Unit of Guatemala. This 4-year Program recruited two one-year fellows and provided funding to define a research topic, write a protocol and implement the research. Strong emphasis is placed on developing skills in knowledge translation and exchange to bridge the "know-do" gap. Close mentoring relationships between the Principal Investigator and former and current fellows are fostered through the Program. The mentoring Program has generated strategic data to support the implementation of sound chronic disease control strategies, mainly related to tobacco control. Results have been presented nationally and internationally. Research training has included principles of biostatistics and epidemiology, and a journal club. The Program is increasingly generating interest among medical graduates to pursue further research training abroad and is building local research capacity. Fellows and research assistants have created a research network in Guatemala and abroad. The main obstacle the Program faces is ensuring long-term sustainability. A mentoring program can lead to an increase in research interest and capacity in a low-income country with little research infrastructure.

    2014-12-01

    Full Text Available A finales de los años setenta y principios de los ochenta, Guatemala, El Salvador y Nicaragua fueron escenario de una serie de conflictos internos, en gran parte como resultado de las desigualdades económicas y sociales, y de regímenes políticos represivos, alimentados por las políticas de las grandes superpotencias de la época. Después de la firma de los acuerdos de paz en 1996, la presencia de empresas de seguridad privada en Guatemala se ha incrementado en forma significativa en relación con el ambiente de inseguridad y la demanda de protección por parte de la sociedad en general. La prestación del servicio de seguridad por el sector privado constituye un reto al papel del Estado como protagonista principal de los asuntos de salvaguardia y garante del amparo físico y patrimonial de los ciudadanos. En ausencia de un sistema legal eficiente o de una estructura regulatoria, estas actividades del sector privado plantean el tema de la legalidad, legitimidad y entrega de cuentas en la esfera de la política de seguridad. Este ensayo tiene como objetivo analizar el estado del control y la supervisión del sector privado en el ámbito de la seguridad pública de Guatemala.

    CONCLUSION: Although there are no available data in the literature to confirm or reject the contribution of the chronic nail infection to the malignant process, we emphasise the importance of this co-existence regarding the possible disguising of the malignant process. An early biopsy of a chronic persistent nail lesion may be preventive and beneficial regarding avoiding more aggressive treatments and achieving a favourable prognosis.

  11. Research on interactive genetic-geological models to evaluate favourability for undiscovered uranium resources

    Current methods of evaluating favourability for undiscovered uranium resources are unduly subjective, quite possibly inconsistent and, as a consequence, of questionable reliability. This research is aimed at reducing the subjectivity and increasing the reliability by designing an improved method that depends largely on geological data and their statistical frequency of occurrence. This progress report outlines a genetic approach to modelling the geological factors that controlled uranium mineralization in order to evaluate the favourability for the occurrence of undiscovered uranium deposits of the type modelled. A genetic model is constructed from all the factors that describe the processes, in chronological sequence, that formed uranium deposits thought to have a common origin. The field and laboratory evidence for the processes constitute a geologic-occurrence base that parallels the chronological sequence of events. The genetic model and the geologic-occurrence base are portrayed as two columns of an interactive matrix called the ''genetic-geologic model''. For each column, eight chronological stages are used to describe the overall formation of the uranium deposits. These stages consist of (1) precursor processes; (2) host-rock formation; (3) preparation of host-rock; (4) uranium-source development; (5) transport of uranium; (6) primary uranium deposition; (7) post-deposition modification; and (8) preservation. To apply the genetic-geological model to evaluate favourability, a question is posed that determines the presence or absence of each attribute listed under the geologic-occurrence base. By building a logic circuit of the attributes according to either their essential or non-essential nature, the resultant match between a well-documented control area and the test area may be determined. The degree of match is a measure of favourability for uranium occurrence as hypothesized in the genetic model

    Full Text Available This article challenges two general assumptions that have guided the study of Mexican foreign policy in the last four decades. First, that from this policy emerges national consensus; and, secondly that between Mexico and the US there is a “special relation” thanks to which Mexico has been able to develop an autonomous foreign policy. The two assumptions are discussed in light of the impact on Mexican domestic politics of the 1954 USsponsored military coup against the government of government of Guatemala. In Mexico, the US intervention reopened a political fracture that had first appeared in the 1930’s, as a result of President Cárdenas’radical policies that divided Mexican society. These divisions were barely dissimulated by the nationalist doctrine adopted by the government. The Guatemalan Crisis brought some of them into the open. The Mexican President, Adolfo Ruiz Cortines’ priority was the preservation of political stability. He feared the US government might feel the need to intervene in Mexico to prevent a serious disruption of the status quo. Thus, Ruiz Cortines found himself in a delicate position in which he had to solve the conflicts derived from a divided elite and a fractured society, all this under the pressure of US’ expectations regarding a secure southern border.Este artículo ofrece una discusión crítica de dos presupuestos generales que han orientado el estudio de la política exterior mexicana en las últimas cuatro décadas.

    To evaluate the effect of Go4it, a multidisciplinary group education programme for adolescents with overweight or obesity. Uncontrolled intervention study. At the obesity outpatient clinic of the Transmural Research and Treatment Centre for Overweight and Obese Children of the VU University Medical Center, Amsterdam, The Netherlands, a group education programme was developed for adolescents (age 12-18 year) who are overweight or obese. Obese adolescents who were referred to the obesity outpatient clinic were asked to participate. During 7 sessions (one session every two weeks) the adolescents were educated on the health consequences of obesity, diet, physical activity, energy balance, improving self-esteem and how to handle bullying and other difficult situations. All sessions were held in groups of 8-10 adolescents. In addition, two sessions were organised for the parents concerning the health consequences of obesity, diet, and physical activity. Body weight and height, glucose tolerance (by an oral glucose tolerance test; OGTT), and insulin resistance were measured at enrolment into the Go4it programme and 6 months later. In total, 93 adolescents (39 boys, 54 girls) were included with a mean age of 3.9 (SD: 1.7) years. Of those, 69 adolescents (74%) attended at least 6 out of 7 sessions of the education programme. Stabilisation or reduction in obesity levels following completion of Go4it was achieved in 51 (74%) of these participants. 50 adolescents had a second OGTT. The BMI standard deviation score (BMI-sds) decreased by 4.3% for boys (p = 0.020) and 3.3% for girls (p = 0.017). Among girls, fasting blood glucose levels decreased by an average of 0.37 mmol/l (95% CI: 0.14-0.60) and insulin concentrations decreased by an average of 299 pmol/l (95% CI: 71-528). Participation in the Go4it education programme is accompanied by a stabilisation or reduction in the level of obesity and has favourable effects on glucose and insulin metabolism.

    Medical tourism has attracted considerable interest within the Latin American and Caribbean (LAC) region. Governments in the region tout the economic potential of treating foreign patients while several new private hospitals primarily target international patients. This analysis explores the perspectives of a range of medical tourism sector stakeholders in two LAC countries, Guatemala and Barbados, which are beginning to develop their medical tourism sectors. These perspectives provide insights into how beliefs about international patients are shaping the expanding regional interest in medical tourism. Structured around the comparative case study methodology, semi-structured interviews were conducted with 50 medical tourism stakeholders in each of Guatemala and Barbados (n = 100). To capture a comprehensive range of perspectives, stakeholders were recruited to represent civil society (n = 5/country), health human resources (n = 15/country), public health care and tourism sectors (n = 15/country), and private health care and tourism sectors (n = 15/country). Interviews were transcribed verbatim, coded using a collaborative process of scheme development, and analyzed thematically following an iterative process of data review. Many Guatemalan stakeholders identified the Guatemalan-American diaspora as a significant source of existing international patients. Similarly, Barbadian participants identified their large recreational tourism sector as creating a ready source of foreign patients with existing ties to the country. While both Barbadian and Guatemalan medical tourism proponents share a common understanding that intra-regional patients are an existing supply of international patients that should be further developed, the dominant perception driving interest in medical tourism is the proximity of the American health care market. In the short term, this supplies a vision of a large number of Americans lacking adequate health insurance willing to

    Full Text Available En Guatemala el estudio de los cetáceos inició en la década de los sesenta con los primeros registros de varamiento y captura incidental. Sin embargo, pocos trabajos científicos con datos de cetáceos han sido publicados. Con el objetivo de centralizar la información de cetáceos y obtener conocimiento biológico para el desarrollo de planes de manejo y conservación, se realizó una revisión bibliográfica de cetáceos en Guatemala que recaba información de los últimos 50 años. Se obtuvo un total de 1,014 registros de avistamiento (1979-2011, 62 registros de captura incidental (1961/85 y 16 registros de varamientos (1975, 2007-2012, los cuales se analizaron en mapas batimétricos y en mapas de presiones antropogénicas. Se identificaron diecinueve especies pertenecientes a cinco familias de cetáceos, incluyendo Balaenopteridae, Delphinidae, Ziphiidae, Kogiidae y Physeteridae. El esfuerzo y área de muestreo varió durante 1961-2012. Se identificaron diferentes patrones de distribución especie-específicos. La mayoría de avistamientos se registraron cerca de zonas con topografía compleja. Aunque los eventos de captura incidental se registraron únicamente en alta mar, los resultados sugieren que especies de distribución costera se encuentran en zonas con mayor riesgo antropogénico. Se reportaron ocho especies de cetáceos varados, eventos ocurridos principalmente en el departamento de Escuintla desde el año 2007. Debido a la gran diversidad en los patrones de distribución, comportamiento y uso de hábitat de los cetáceos, combinado con los riesgos antropogénicos de la zona, es necesario que se considere un enfoque integral cuando se implementen planes de manejo y conservación marina en Guatemala.

    We describe the Mesoamerican leaf litter weevil genus Plumolepilius Barrios-Izás & Anderson, new genus (Coleoptera: Curculionidae: Molytinae: Conotrachelini) (type species P. trifiniensis Barrios-Izás & Anderson, new species), species of which inhabit mountain ecosystems from the state of Chiapas in southeastern Mexico to northern Panama. In this paper we describe nine new species from Mexico, Guatemala, and El Salvador: P. trifiniensis Barrios-Izás & Anderson, new species (El Salvador and Guatemala); P. branstetteri Barrios-Izás & Anderson, new species (Guatemala and Mexico); P. longinoi Barrios-Izás & Anderson, new species (Guatemala and Mexico); P. cortezi Barrios-Izás & Anderson, new species (Guatemala and Mexico); P. canoi Barrios-Izás & Anderson, new species (Guatemala); P. schusteri Barrios-Izás & Anderson, new species (Guatemala and Mexico); P. daryi Barrios-Izás & Anderson, new species (Guatemala); P. yolnabajensis Barrios-Izás & Anderson, new species (Guatemala); and P. macalajauensis Barrios-Izás & Anderson, new species (Guatemala).        The genus and the species are named and described, information on their geographical distributions is given and images of the habitus of both sexes and the aedeagus are presented. A key to the species of Plumolepilius based on males is included.        The monophyly of Plumolepilius was confirmed by a parsimony analysis of external and male aedeagus morphology and the genus is best characterized by the presence of plumose scales lining the prosternal channel. Phylogenetic analysis supports that Lepilius Champion 1905 is the sister genus of Plumolepilius.

    Limited data are available regarding the molecular epidemiology of Mycobacterium tuberculosis (Mtb) strains circulating in Guatemala. Beijing-lineage Mtb strains have gained prevalence worldwide and are associated with increased virulence and drug resistance, but there have been only a few cases reported in Central America. Here we report the first whole genome sequencing of Central American Beijing-lineage strains of Mtb. We find that multiple Beijing-lineage strains, derived from independent founding events, are currently circulating in Guatemala, but overall still represent a relatively small proportion of disease burden. Finally, we identify a specific Beijing-lineage outbreak centered on a poor neighborhood in Guatemala City. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Limited funding for medical technology, low levels of education and poor infrastructure for delivering and maintaining technology severely limit medical decision support in low- and middle-income countries. Perinatal and maternal mortality is of particular concern with millions dying every year from potentially treatable conditions. Guatemala has one of the worst maternal mortality ratios, the highest incidence of intra-uterine growth restriction (IUGR), and one of the lowest gross national incomes per capita within Latin America. To address the lack of decision support in rural Guatemala, a smartphone-based system is proposed including peripheral sensors, such as a handheld Doppler for the identification of foetal compromise. Designed for use by illiterate birth attendants, the system uses pictograms, audio guidance, local and cloud processing, SMS alerts and voice calling. The initial prototype was evaluated on 22 women in highland Guatemala. Results were fed back into the refinement of the system, currently undergoing RCT evaluation.

    A host of large uranium deposits have been successively discovered abroad by means of geological exploration, metallogenetic model studies and the application of new geophysical and geochemical methods since 1970's. Thorough undertaking geological research relevant to prospecting for super large uranium deposits have attracted great attention of the worldwide geological circle. The important task for the vast numbers of uranium geological workers is to make an afford to discover more numerous large and super large uranium deposits in China. The author comprehensively analyses the regional geological setting and geological metallogenetic conditions for the super large uranium deposits in the world. Comparative studies have been undertaken and the prospecting direction and favourable target areas for the exploration of super large uranium deposits in China have been proposed

    Improving understanding on groundwater chemistry is a key priority for water supply from groundwater resources, especially in developing countries. A hydrochemical study was performed in an area of SW Guatemala (Samalà River basin), where water supply to population is groundwater-based and no systematic studies on its groundwater resources have been performed so far. Traditional hydrochemical analyses on major ions and some trace elements metals coupled with chemometric approach were performed, including principal component analysis and hierarchical clustering analysis. Results evidence that chemical differentiation is linked to the spatial distribution of sampled waters. The most common hydrochemical facies, bicarbonate calcium and magnesium, is linked to infiltration of meteoric waters in recharge areas represented by highlands surrounding Xela caldera, a wide plateau where most of population is concentrated. This trend undergoes chemical evolution in proximity of active volcanic complexes in the southern area, with enrichment in sulphate, chloride and magnesium. Chemical evolution also occurs towards the centre of Xela caldera due to slow circulation in aquifer and consequent sodium enrichment due to ion exchange with the porous medium. Water quality did not reveal severe concerns, even though some sources of contamination could be identified; in particular, agriculture and urban wastewater could be responsible for observed threshold exceedances in nitrate and lead. This integrated multi-approach to hydrochemical data interpretation yielded to the achievement of important information that poses the basis for future groundwater protection in an area where main water features were almost unknown.

    Guatemala is experiencing an increasing burden of cancer but lacks capacity for cancer prevention, control and research. In partnership with a medical school in the United States of America, a multidisciplinary Cancer Control Research Training Institute was developed at the Instituto de Cancerología (INCAN) in Guatemala City. This institute provided a year-long training programme for clinicians that focused on research methods in population health and sociocultural anthropology. The programme included didactic experiences in Guatemala and the United States as well as applied training in which participants developed research protocols responsive to Guatemala's cancer needs. Although INCAN is the point of referral and service for Guatemala's cancer patients, the institute's administration is also interested in increasing cancer research - with a focus on population health. INCAN is thus a resource for capacity building within the context of cancer prevention and control. Trainees increased their self-efficacy for the design and conduct of research. Value-added benefits included establishment of an annual cancer seminar and workshops in cancer pathology and qualitative analysis. INCAN has recently incorporated some of the programme's components into its residency training and established a research department. A training programme for clinicians can build cancer research capacity in low- and middle-income countries. Training in population-based research methods will enable countries such as Guatemala to gather country-specific data. Once collected, such data can be used to assess the burden of cancer-related disease, guide policy for reducing it and identify priority areas for cancer prevention and treatment.

    We continue to build support for the proposal to use H II galaxies (HIIGx) and giant extragalactic H II regions (GEHR) as standard candles to construct the Hubble diagram at redshifts beyond the current reach of Type Ia supernovae. Using a sample of 25 high-redshift HIIGx, 107 local HIIGx, and 24 GEHR, we confirm that the correlation between the emission-line luminosity and ionized-gas velocity dispersion is a viable luminosity indicator, and use it to test and compare the standard model ΛCDM and the Rh = ct universe by optimizing the parameters in each cosmology using a maximization of the likelihood function. For the flat ΛCDM model, the best fit is obtained with Ω _m= 0.40_{-0.09}^{+0.09}. However, statistical tools, such as the Akaike (AIC), Kullback (KIC) and Bayes (BIC) Information Criteria favour Rh = ct over the standard model with a likelihood of ≈94.8-98.8 per cent versus only ≈1.2-5.2 per cent. For wCDM (the version of ΛCDM with a dark-energy equation of state wde ≡ pde/ρde rather than wde = wΛ = -1), a statistically acceptable fit is realized with Ω _m=0.22_{-0.14}^{+0.16} and w_de= -0.51_{-0.25}^{+0.15} which, however, are not fully consistent with their concordance values. In this case, wCDM has two more free parameters than Rh = ct, and is penalized more heavily by these criteria. We find that Rh = ct is strongly favoured over wCDM with a likelihood of ≈92.9-99.6 per cent versus only 0.4-7.1 per cent. The current HIIGx sample is already large enough for the BIC to rule out ΛCDM/wCDM in favour of Rh = ct at a confidence level approaching 3σ.

The analysis of these connections is fundamental to understand some of the contemporary social dynamics affecting not only that country.

    Intimate partner violence (IPV) is a significant public health problem with a demonstrated link to increased sexually transmitted infection (STI)/HIV-related risk and vulnerability. While IPV is an important issue in Central America, the link to STI/HIV risk has not been explored in this region. In this study, the relationship between emotional and physical/sexual IPV and the STI/HIV-related risk behaviors of sex worker patronage and infidelity is assessed among male IPV perpetrators using data from a national survey conducted in 2009 in Guatemala (n = 4773 married/partnered men). Bivariate associations between background characteristics and emotional and physical IPV perpetration were explored. Logistic regression models were run to test associations between IPV for each sexual risk behavior. Perpetration of emotional and physical/sexual IPV was more common among married/partnered men who were older than 24, had more education, lived in urban areas, or were in common law versus married unions. Reports of past-year emotional IPV perpetration increased as wealth quintile increased. After adjusting for demographics and other characteristics, physical/sexual IPV perpetration was associated with past-year infidelity (AOR 1.9, 95% CI: 1.1-3.6). Lifetime emotional IPV (AOR 1.4, 95% CI: 1.1-1.7) and physical/sexual IPV 1.6 (95% CI 1.2-2.0) were positively associated with a history of sex worker patronage. Endorsement of traditional gender role norms showed a marginally positive association with past-year infidelity in the adjusted model (AOR 1.3, 95% CI 1.0-1.8). The study findings from Guatemala reinforce the growing evidence globally that male IPV perpetrators are more likely to engage in risky sexual behavior, including sex worker patronage and main partner infidelity. The concurrency of violence and increased STI/HIV risk may compound the health risks for female victims of IPV who also face injury and psychological trauma.

    Full Text Available The western highlands of Guatemala lie within the area where maize was first domesticated, and maize remains central to farmers' livelihood security. Over 50% of the population in the region are in poverty, and over 48% suffer from chronic malnutrition. Development efforts have focused on improved land management, crop diversification, and improved access to markets, especially for high-value vegetable crops such as snow peas. As a result of successful initiatives worldwide, more attention is being directed at the extent to which farmers can benefit from market opportunities for indigenous crops by receiving a price premium for providing the environmental service of conserving agricultural biodiversity. Such an approach bridges the gap between poverty alleviation and in situ conservation. We explored this potential development pathway through both qualitative and quantitative research. Focus groups were conducted in 5 communities in the maize-growing highlands of Guatemala, followed by a survey of 989 farm households in 59 locations. Our results show that most farmers in the western highlands of Guatemala are severely maize deficient; on average, farm households produce enough maize for only 6.9 months of consumption a year and are forced to purchase maize to meet basic consumption needs. The results are in sharp contrast to research conducted in highland communities in neighboring Mexico, where many farmers are able to sell their maize in relatively lucrative specialty maize markets. In the context of renewed interest in reducing poverty in Central America, our research suggests that rather than focus on market development for local maize varieties, development efforts should target other types of interventions.

    Full Text Available La diabetes mellitus es un problema de salud con alcances económicos y sociales. La prevalencia mundial está aumentando: se estima que para 1985 había 30 millones de personas con diabetes, 177 millones en el año 2000 y se estima que para el año 2030 habrá 438 millones de diabéticos. En Guatemala el 8% de la población tiene diabetes y se desconoce el porcentaje no diagnosticado y en pre-diabetes; además el país tiene índices de obesidad, sobrepeso y sedentarismo altos, situación que predispone a la aparición de la enfermedad. En el mundo cada 6 segundos muere alguien a causa de complicaciones relacionadas con diabetes y en Guatemala ocupa la tercera causa de mortalidad general. Existen varios tipos de diabetes, sin embargo, el ensayo se enfoca en la diabetes tipo 2 debido a que representa el 90% de los casos pero sobre todo por que es prevenible. Para el autor existen tres momentos importantes de los pacientes diabéticos: (1 paciente sano y con riesgo qué enfermará de diabetes, (2 paciente diabético que tendrá complicaciones y (3 pacientes con complicaciones que morirán. En los tres momentos se puede intervenir directamente, sin embargo, existen deficiencias como la ausencia de programas de prevención y la ineficiencia del sistema asistencial público. El autor propone posibles soluciones en base a evidencia científica para detener el aumento de casos de diabetes mellitus, disminuir las complicaciones micro y macro vasculares en los pacientes y principalmente, generar una cultura preventiva en Guatemala.

    This paper presents the analysis of installing the vertical axis wind turbines between the building passages on an island in Stockholm, Sweden. Based on the idea of wind speed amplification due to the venture effect in passages, practical measurements were carried out to study the wind profile for a range of passage widths in parallel building passages. Highest increment in wind speed was observed in building passages located on the periphery of sland as wind enters from free field. Wind mapping was performed in the island to choose the most favourable location to install the vertical axis wind turbines (VAWT). Using the annual wind speed data for location and measured amplification factor, energy potential of the street was calculated. This analysis verified that small vertical axis wind turbines can be installed in the passage centre line provided that enough space is provided for traffic and passengers.

    Although fire was arguably the primary tool used by the Maya to alter the landscape and extract resources, little attention has been paid to biomass burning in paleoenvironmental reconstructions from the Maya lowlands. Here we report two new well-dated, high-resolution records of biomass burning based on analysis of macroscopic fossil charcoal recovered from lacustrine sediment cores. The records extend from the early Holocene, through the full arc of Maya prehistory, the Colonial, and post-Colonial periods ( 9000 cal yr BP to the present). (Hereafter BP) The study sites, Lago Paixban and Lago Puerto Arturo, are located in northern Peten, Guatemala. Results provide the first quantitative analysis from the region demonstrating that frequent fires have occurred in the closed canopy forests since at least the early Holocene ( 9000 BP), prior to occupation by sedentary agriculturalists. Following the arrival of agriculture around 4600 BP, the system transitioned from climate controlled to anthropogenic control. During the Maya period, changes in fire regime are muted and do not appear to be driven by changes in climate conditions. Low charcoal influx and fire frequency in the Earliest Preclassic period suggest that land use strategies may have included intensive agriculture much earlier than previously thought. Preliminary results showing concentrations of soot/black-carbon during the middle and late Preclassic periods are lower than modern background values, providing intriguing implications regarding the efficiency of Maya fuel consumption.

    This study assessed correlates of inconsistent condom use with casual partners and the prevalence of sexual risk behaviors and STIs in the Mexico/Guatemala border region using a sample of 392 migrants (303 men, 85 women) who reported current substance use or problem drinking. We ran separate univariate logistic regression models for men and women, and multivariate logistic regression models for men only. Prevalence of syphilis was 1.2% among women and 2.3% among men; HIV prevalence was 2.4% among women and 1.3% among men. Inconsistent condom use with casual partners was higher in women with greater education and lower among women who sold sex. In men, less access to free condoms, drug use with sexual partners, and drug use before sex were independently associated with inconsistent condom use with casual partners. Sexual and substance use risk behaviors were common, and HIV/STI prevention efforts should target both genders and expand beyond most-at risk populations.

    Exposure to household wood smoke from cooking is a risk factor for chronic obstructive lung disease among women in developing countries. The Randomized Exposure Study of Pollution Indoors and Respiratory Effects (RESPIRE) is a randomized intervention trial evaluating the respiratory health effects of reducing indoor air pollution from open cooking fires. A total of 504 rural Mayan women in highland Guatemala aged 15-50 years, all using traditional indoor open fires, were randomized to either receive a chimney woodstove (plancha) or continue using the open fire. Assessments of chronic respiratory symptoms and lung function and individual measurements of carbon monoxide exposure were performed at baseline and every 6 months up to 18 months. Use of a plancha significantly reduced carbon monoxide exposure by 61.6%. For all respiratory symptoms, reductions in risk were observed in the plancha group during follow-up; the reduction was statistically significant for wheeze (relative risk = 0.42, 95% confidence interval: 0.25, 0.70). The number of respiratory symptoms reported by the women at each follow-up point was also significantly reduced by the plancha (odds ratio = 0.7, 95% confidence interval: 0.50, 0.97). However, no significant effects on lung function were found after 12-18 months. Reducing indoor air pollution from household biomass burning may relieve symptoms consistent with chronic respiratory tract irritation.

    The lowland Maya site of Ceibal, Guatemala, had a long history of occupation, spanning from the Middle Preclassic Period through the Terminal Classic (1000 BC to AD 950). The Ceibal-Petexbatun Archaeological Project has been conducting archaeological investigations at this site since 2005 and has obtained 154 radiocarbon dates, which represent the largest collection of radiocarbon assays from a single Maya site. The Bayesian analysis of these dates, combined with a detailed study of ceramics, allowed us to develop a high-precision chronology for Ceibal. Through this chronology, we traced the trajectories of the Preclassic collapse around AD 150-300 and the Classic collapse around AD 800-950, revealing similar patterns in the two cases. Social instability started with the intensification of warfare around 75 BC and AD 735, respectively, followed by the fall of multiple centers across the Maya lowlands around AD 150 and 810. The population of Ceibal persisted for some time in both cases, but the center eventually experienced major decline around AD 300 and 900. Despite these similarities in their diachronic trajectories, the outcomes of these collapses were different, with the former associated with the development of dynasties centered on divine rulership and the latter leading to their downfalls. The Ceibal dynasty emerged during the period of low population after the Preclassic collapse, suggesting that this dynasty was placed under the influence from, or by the direct intervention of, an external power.

  18. Does consumption of processed foods explain disparities in the body weight of individuals? The case of Guatemala.

    Overweight/obesity, caused by the 'nutrition transition', is identified as one of the leading risk factors for non-communicable mortality. The nutrition transition in developing countries is associated with a major shift from the consumption of staple crops and whole grains to highly and partially processed foods. This study examines the contribution of processed foods consumption to the prevalence of overweight/obesity in Guatemala using generalized methods of moments (GMM) regression. The results show that all other things remaining constant, a 10% point increase in the share of partially processed foods from the total household food expenditure increases the BMI of family members (aged 10 years and above) by 3.95%. The impact of highly processed foods is much stronger. A 10% point increase in the share of highly processed food items increases the BMI of individuals by 4.25%, ceteris paribus. The results are robust when body weight is measured by overweight/obesity indicators. These findings suggest that increasing shares of partially and highly processed foods from the total consumption expenditure could be one of the major risk factors for the high prevalence of overweight/obesity in the country.
