Baseline evaluation of nutritional status and government feeding programs in Chiclayo, Peru.
Gross, Rainer; Lechtig, Aarón; López de Romaña, Daniel
2006-01-01
Because of the rapid growth of the urban population in Peru, food and nutrition insecurity will occur increasingly in this population. For appropriate policy setting and programming, the food and nutrition situation of the urban poor requires better understanding. To gain information about the nature, magnitude, severity, and causes of the nutritional problems of the population in low-income areas of the city of Chiclayo, Peru. A cross-sectional nutrition survey was conducted in 1,604 households, covering children under 5 years of age and their parents. The prevalence rates of stunting, wasting, overweight. and anemia in children were 15.4%, 1.3%, 4.6%, and 65.7%, respectively; one third of adults were overweight, and one tenth were obese; 2.1% of the mothers were underweight; and 34.3% of mothers and 12.2% of fathers had anemia. Governmental feeding programs did not address these problems adequately. Interventions must have adequate targeting; address appropriate responses at the household, community, and national levels; and reduce stunting, obesity, and iron-deficiency anemia.

In Peru, health protection rights and the National Health Authority (SUSALUD) coexist with the aim to ensure that every Peruvian may exercise his/her rights. According to the L.D. (Spanish: Decreto legislativo) N° 1158, strategies must be deployed to ensure effective decentralization and ensure compliance with user rights. As a result, the Northern Macro-regional Intendance (IMRN) was created, with headquarters in the city of Chiclayo, and a coverage area including Lambayeque, Tumbes, Piura, Cajamarca, La Libertad, and Amazonas. The northern macro-region promotes information dissemination, coordination, and local participation in health activities, with an emphasis on handling complaints and claims as well as implementation and operation support of user boards (JUS). After 6 months, implementation of the IMRN experience is undergoing consolidation.

The northern Altiplano plateau of southern Peru and northern Bolivia is one of the highest topographic features on the Earth, flanked by Western and Eastern Cordillera along its margin. It has strongly influenced the local and far field lithospheric deformation since the early Miocene (Masek et al., 1994). Previous studies have emphasized the importance of both the crust and upper mantle in the evolution of Altiplano plateau (McQuarrie et al., 2005). Early tomographic and receiver function studies, south of 16° S, show significant variations in the crust and upper mantle properties in both perpendicular and along strike direction of the Altiplano plateau (Dorbath et. al., 1993; Myers et al., 1998; Beck and Zandt, 2002). In order to investigate the nature of subsurface lithospheric structure below the northern Altiplano, between 15-18° S, we have determined three-dimensional seismic tomography models for Vp and Vs using P and S-wave travel time data from two recently deployed local seismic networks of CAUGHT and PULSE. We also used data from 8 stations from the PERUSE network (PERU Subduction Experiment). Our preliminary tomographic models show a complex variation in the upper mantle velocity structure with depth, northwest and southeast of lake Titicaca. We see the following trend, at ~85 km depth, northwest of lake Titicaca: low Vp and Vs beneath the Western Cordillera, high Vs beneath the Altiplano and low Vp and Vs beneath the Eastern Cordillera. This low velocity anomaly, beneath Eastern Cordillera, seems to coincide with Kimsachata, a Holocene volcano in southern Peru. At depth greater than ~85 km: we find high velocity anomaly beneath the Western Cordillera and low Vs beneath the Altiplano. This high velocity anomaly, beneath Western Cordillera, coincides with the well-located Wadati-Benioff zone seismicity and perhaps represents the subducting Nazca slab. On the southeast of lake Titicaca, in northern Bolivia, we see a consistently high velocity anomaly

Shadows of the colonial past--diverging plant use in Northern Peru and Southern Ecuador.
Bussmann, Rainer W; Sharon, Douglas
2009-02-02
This paper examines the traditional use of medicinal plants in Northern Peru and Southern Ecuador, with special focus on the Departments of Piura, Lambayeque, La Libertad, Cajamarca, and San Martin, and in Loja province, with special focus on the development since the early colonial period. Northern Peru represents the locus of the old Central Andean "Health Axis." The roots of traditional healing practices in this region go as far back as the Cupisnique culture early in the first millennium BC. Northern Peru and Southern Ecuador share the same cultural context and flora but show striking differences in plant use and traditional knowledge. Two hundred fifteen plant species used for medicinal purposes in Ecuador and 510 plant species used for medicinal purposes in Peru were collected, identified,. and their vernacular names, traditional uses, and applications recorded. This number of species indicates that the healers, market vendors, and members of the public interviewed in Peru still have a very high knowledge of plants in their surroundings, which can be seen as a reflection of the knowledge of the population in general. In Ecuador much of the original plant knowledge has already been lost. In Peru, 433 (85%) were Dicotyledons, 46 (9%) Monocotyledons, 21 (4%) Pteridophytes, and 5 (1%) Gymnosperms. Three species of Giartina (Algae) and one species of the Lichen genus Siphula were used. The families best represented were Asteraceae with 69 species, Fabaceae (35), Lamiaceae (25), and Solanaceae (21). Euphorbiaceae had 12 species, and Poaceae and Apiaceae each accounted for 11 species. In Ecuador the families best represented were Asteraceae (32 species), Euphorbiaceae, Lamiaceae, and Solanaceae (11 species each), and Apiaceae, Fabaceae, Lycopodiaceae (9 species each). One hundred eighty-two (85%) of the species used were Dicotyledons, 20 Monocotyledons (9.3%), 12 ferns (5.5%), and one unidentified lichen was used. Most of the plants used (83%) were native to Peru

Costs of the multimicronutrient supplementation program in Chiclayo, Peru.
Lechtig, Aarón; Gross, Rainer; Paulini, Javier; de Romaã, Daniel López
2006-01-01
There is little information on the cost parameters of weekly multimicronutrient supplementation programs. To assess the cost parameters and cost-effectiveness of a weekly multimicronutrient supplementation program in an urban population of Peru. Data from the Integrated Food Security Program (Programa Integrado de Seguridad Alimentaria [PISA]), which distributed capsules and foodlets to women and adolescent girls and to children under five, were extrapolated to a population of 100,000 inhabitants. The annual cost per community member was US$1.51. The cost-effectiveness ratio was US$0.12 per 1% of prevented anemia per community member. These costs are in the upper margin of iron supplementation alone. They will decrease notably when weekly multimicronutrient supplementation programs are integrated into health packages and participation by women increases. Focusing on micronutrient deficiencies would prevent these problems, and food-distribution programs would be effectively targeted to food-deficient populations.

Ground-water resources of the Lambayeque Valley, Department of Lambayeque, northern Peru
Schoff, Stuart L.; Sayan, M. Juan Luis
1969-01-01
Ground water in the Lambayeque Valley has been developed mainly for irrigation of sugarcane and rice. The locality is on the coastal plain of northern Peru, about 650 km (kilometers) northwest of Lima, the national capital. The area considered in this study is about 1,670 sq km (square kilometers) and is mainly on the alluvial fan of Rio Chancay and entirely in the Department of Lambayeque. Chiclayo, the departmental capital and largest city, has a population, of about 46,000. The climate is hot and virtually rainless. Agriculture is dependent on irrigation. The available water, whether in stream s or underground, is introduced from the Andean highlands by Rio Chancay. Rocks in the area range in age from Cretaceous, or possibly Jurassic, to Quaternary and in lithology from dense and hard igneous, sedimentary, and metamorphic rocks to unconsolidated sediments. The bedrock contains and yields water only in small quantities, if at all. The principal water-bearing strata are in the alluvium comprising the fan of Rio Chancay. Where ground water in the alluvium has been most intensively developed, the productive zone is within 20 m (meters) of the land surface and is composed approximately as follows: (1) relatively impermeable soil, clay, and clayey sand, 5 to 10 m thick, (2) permeable sand and gravel, 6 to 10 m thick, at places including one or more layers of clay, so that several water-bearing beds are distinguishable, and (3) relatively impermeable mixtures of clay, sand, and gravel extending below the bottom of wells. Unit 3 in the deepest test continued to 102 m. Unit 2 is the principal source of water tapped by irrigation wells. In the northern part of the area wells locally yield water rather freely from strata as deep as 73 m, but elsewhere in the area the strata deeper than 20 m are not very productive. Wells at and near Chiclayo yield only small amounts, and the deepest well disclosed, in 100 m of material, only 5.5 m of material that can be considered as

War and early state formation in the northern Titicaca Basin, Peru.
Stanish, Charles; Levine, Abigail
2011-08-23
Excavations at the site of Taraco in the northern Titicaca Basin of southern Peru indicate a 2,600-y sequence of human occupation beginning ca. 1100 B.C.E. Previous research has identified several political centers in the region in the latter part of the first millennium B.C.E. The two largest centers were Taraco, located near the northern lake edge, and Pukara, located 50 km to the northwest in the grassland pampas. Our data reveal that a high-status residential section of Taraco was burned in the first century A.D., after which economic activity in the area dramatically declined. Coincident with this massive fire at Taraco, Pukara adopted many of the characteristics of state societies and emerged as an expanding regional polity. We conclude that organized conflict, beginning approximately 500 B.C.E., is a significant factor in the evolution of the archaic state in the northern Titicaca Basin.

Full Text Available The smooth hammerhead shark Sphyrna zygaena (Linnaeus, 1758 is one of the elasmobranch species most used for human consumption in Peru. However, the level of mercury in hammerhead muscle tissue is unknown. This study assessed the level of mercury found in the muscle of hammerhead sharks and its relation with human health. Moreover, we evaluated the relationship between shark body size and mercury levels. We analyzed 27 muscle samples of neonates and juveniles captured in northern Peru. Mercury concentrations varied between 0.13 and 0.86 mg kg-1 wet weight. Moreover, we found a negative and significant relationship between shark body size and mercury levels. This study represents the first evaluation of mercury levels of sharks in Peru. Although the values found do not exceed levels recommended by the World Health Organization (< 1 mg kg-1, we recommend expanding this study to include other size classes of sharks as well as other marine resources used for human consumption.

Traditional medicinal plant use in Northern Peru: tracking two thousand years of healing culture
Bussmann, Rainer W; Sharon, Douglas
2006-01-01
This paper examines the traditional use of medicinal plants in Northern Peru, with special focus on the Departments of Piura, Lambayeque, La Libertad, Cajamarca, and San Martin. Northern Peru represents the center of the old Central Andean "Health Axis," stretching from Ecuador to Bolivia. The roots of traditional healing practices in this region go at least as far back as the Moche period (AC 100–800). Although about 50% of the plants in use reported in the colonial period have disappeared from the popular pharmacopoeia, the plant knowledge of the population is much more extensive than in other parts of the Andean region. 510 plant species used for medicinal purposes were collected, identified and their vernacular names, traditional uses and applications recorded. The families best represented were Asteraceae with 69 species, Fabaceae (35), Lamiaceae (25), and Solanaceae (21). Euphorbiaceae had twelve species, and Apiaceae and Poaceae 11 species. The highest number of species was used for the treatment of "magical/ritual" ailments (207 species), followed by respiratory disorders (95), problems of the urinary tract (85), infections of female organs (66), liver ailments (61), inflammations (59), stomach problems (51) and rheumatism (45). Most of the plants used (83%) were native to Peru. Fresh plants, often collected wild, were used in two thirds of all cases, and the most common applications included the ingestion of herb decoctions or the application of plant material as poultices.

Mineral resources of Peru's ancient societies
Brooks, W.E.
2003-01-01
Northern Peru has an exceptionally rich archaeological heritage that includes metalwork, ceramics and textiles. The success of at least a half-dozen pre-Columbian societies dating back 3,000 years and subsequent Spanish colonization in the 1400s has rested on the effective use of northern Peru's abundant resources. In the summer of 2000, my son Matt and I learned about that connection firsthand by volunteering at the Santa Rita B archaeological site in the Chao Valley near Trujillo in northern Peru. Riding donkey-back through the Andes and talking with local people, we got our hands dirty in the rich archaeology and geology of the area. We were able to correlate mineral occurrences to their various roles in society - opening a window into the region's fascinating past. From construction to metallurgy, pre-Columbian societies flourished and advanced because of their understanding and use of the available mineral resources.

The Globalization of Traditional Medicine in Northern Peru: From Shamanism to Molecules
Bussmann, Rainer W.
2013-01-01
Northern Peru represents the center of the Andean “health axis,” with roots going back to traditional practices of Cupisnique culture (1000 BC). For more than a decade of research, semistructured interviews were conducted with healers, collectors, and sellers of medicinal plants. In addition, bioassays were carried out to evaluate the efficacy and toxicity of plants found. Most of the 510 species encountered were native to Peru (83%). Fifty percent of the plants used in colonial times have disappeared from the pharmacopoeia. Market vendors specialized either on common and exotic plants, plants for common ailments, and plants only used by healers or on plants with magical purposes. Over 974 preparations with up to 29 different ingredients were used to treat 164 health conditions. Almost 65% of the medicinal plants were applied in these mixtures. Antibacterial activity was confirmed in most plants used for infections. Twenty-four percent of the aqueous extracts and 76% of the ethanolic extracts showed toxicity. Traditional preparation methods take this into account when choosing the appropriate solvent for the preparation of a remedy. The increasing demand for medicinal species did not increase the cultivation of medicinal plants. Most species are wild collected, causing doubts about the sustainability of trade. PMID:24454490

Vector-borne transmission of Trypanosoma cruzi is seen exclusively in the Americas where an estimated 8 million people are infected with the parasite. Significant research in southern Peru has been conducted to understand T. cruzi infection and vector control, however, much less is known about the burden of infection and epidemiology in northern Peru. A cross-sectional study was conducted to estimate the seroprevalence of T. cruzi infection in humans (n=611) and domestic animals [dogs (n=106) and guinea pigs (n=206)] in communities of Cutervo Province, Peru. Sampling and diagnostic strategies differed according to species. An entomological household study (n=208) was conducted to identify the triatomine burden and species composition, as well as the prevalence of T. cruzi in vectors. Electrocardiograms (EKG) were performed on a subset of participants (n=90 T. cruzi infected participants and 170 age and sex-matched controls). The seroprevalence of T. cruzi among humans, dogs, and guinea pigs was 14.9% (95% CI: 12.2-18.0%), 19.8% (95% CI: 12.7-28.7%) and 3.3% (95% CI: 1.4-6.9%) respectively. In one community, the prevalence of T. cruzi infection was 17.2% (95% CI: 9.6-24.7%) among participants Peru.

Only one species of triatomine was found, Panstrongylus lignarius, formerly P. herreri. Approximately forty percent (39.9%, 95% CI: 33.2-46.9% of surveyed households were infested with this vector and 14.9% (95% CI: 10.4-20.5% had at least one triatomine positive for T. cruzi. The cardiac abnormality of right bundle branch block was rare, but only identified in seropositive individuals.Our research documents a substantial prevalence of T. cruzi infection in Cutervo and highlights a need for greater attention and vector control efforts in northern Peru.

This work summarises such information from northern Peru, and presents new data on Rhodnius ecuadoriensis - an important local vector infesting 10-35% of dwellings in some zones. Three species are strongly synanthropic and may be suitable targets for chemical control of domestic/peridomestic bug populations. Panstrongylus herreri, the main domestic vector in the area, is probably present in sylvatic ecotopes in the Marañón river system. R. ecuadoriensis and Triatoma dimidiata seem exclusively domestic; biogeographical and ecological data suggest they might have spread in association with humans in northern Peru. Confirmation of this hypothesis would result in a local eradication strategy being recommended. Presence of trypanosome natural infection was assessed in 257 R. ecuadoriensis; Trypanosoma rangeli was detected in 4% of bugs. Six further triatomine species are potential disease vectors in the region (T. carrioni, P. chinai, P. rufotuberculatus, P. geniculatus, R. pictipes, and R. robustus, whilst Eratyrus mucronatus, E. cuspidatus, Cavernicola pilosa, Hermanlentia matsunoi, and Belminus peruvianus have little or no epidemiological significance. A strong community-based entomological surveillance system and collaboration with Ecuadorian public health authorities and researchers are recommended.

The plant species reported here are traditionally used in Northern Peru for a wide range of illnesses. Most remedies are prepared as ethanol or aqueous extracts and then ingested. The aim of this study was to evaluate the potential toxicity of these extracts. The toxicity of ethanolic and water extracts of 341 plant species was determined using a brine-shrimp assay. Overall 24% of the species in water extract and 76% of the species in alcoholic extract showed elevated toxicity levels to brine-shrimp. Although in most cases multiple extracts of the same species showed very similar toxicity values, in some cases the toxicity of different extracts of the same species varied from non-toxic to highly toxic. Traditional preparation methods take different toxicity levels in aqueous and ethanol extracts into account when choosing the appropriate solvent for the preparation of a remedy.

Currently, in rural communities from the Peruvian northern coast, it is common to find a climate of distrust and pessimism that accompanies the lack of coordinated social action and community participation among residents. This study analyzes the relationships that people develop with regard to the place where they live in, how it associates to the ways they participate in their community and the relationship that these two variables have with the perceived emotional climate, in a rural community from the northern coast of Peru (n = 81). Results indicate that place identity is significantly associated with a high community participation and a climate of trust in the community. Finally, a Path Analysis is performed to analyze comprehensively the relationship between these variables. The results suggest that place identity does have an influence on perceived positive climate in the community, being mediated by the dimensions of community participation.

Since 1983, cases of diseased donkeys and horses with symptoms similar to those produced by alphaviruses were identified in two departments in northern Peru; however serological testing ruled out the presence of those viruses and attempts to isolate an agent were also unproductive. In 1997, also in northern Peru, two new orbiviruses were discovered, each recognized as a causative agent of neurological diseases in livestock and domestic animals and, at the same time, mosquitoes were found to be infected with these viruses. Peruvian horse sickness virus (PHSV) was isolated from pools of culicid mosquitoes, Aedes serratus and Psorophora ferox, and Yunnan virus (YUOV) was isolated from Aedes scapularis in the subtropical jungle (upper jungle) located on the slope between the east side of the Andes and the Amazonian basin in the Department of San Martín. Both viruses later were recovered from mosquitoes collected above the slope between the west side of the Andes and the coast (Department of Piura) in humid subtropical areas associated with the Piura River basin. In this region, PHSV was isolated from Anopheles albimanus and YUOV was isolated from Ae. scapularis. We discuss the ecology of vector mosquitoes during the outbreaks in the areas where these mosquitoes were found. © 2015 The Society for Vector Ecology.

The plant species reported here are traditionally used in Northern Peru to treat bacterial infections, often addressed by the local healers as "inflammation". The aim of this study was to evaluate the minimum inhibitory concentration (MIC) of their antibacterial properties against gram-positive and gram-negative bacteria. The antimicrobial activity of ethanolic and water extracts of 141 plant species was determined using a deep-well broth microdilution method on commercially available bacterial strains. The ethanolic extracts of 51 species inhibited Escherichia coli, and 114 ethanolic extracts inhibited Staphylococcus aureus. In contrast, only 30 aqueous extracts showed activity against Escherichia coli and 38 extracts against Staphylococcus aureus. The MIC concentrations were mostly very high and ranged from 0.008 to 256 mg/ml, with only 36 species showing inhibitory concentrations of extracts exhibited stronger activity and a much broader spectrum of action than the aqueous extracts. Hypericum laricifolium, Hura crepitans, Caesalpinia paipai, Cassia fistula, Hyptis sidifolia, Salvia sp., Banisteriopsis caapi, Miconia salicifolia and Polygonum hydropiperoides showed the lowest MIC values and would be interesting candidates for future research. The presence of antibacterial activity could be confirmed in most species used in traditional medicine in Peru which were assayed in this study. However, the MIC for the species employed showed a very large range, and were mostly very high. Nevertheless, traditional knowledge might provide some leads to elucidate potential candidates for future development of new antibiotic agents. Copyright © 2010 Elsevier Ireland Ltd.

Mycobacterium ulcerans disease, Peru.
Guerra, Humberto; Palomino, Juan Carlos; Falconí, Eduardo; Bravo, Francisco; Donaires, Ninoska; Van Marck, Eric; Portaels, Françoise
2008-03-01
Eight adult patients (ages 18-58, 5 women) with Buruli ulcer (BU) confirmed by at least 2 diagnostic methods were seen in a 10-year period. Attempts to culture Mycobacterium ulcerans failed. Five patients came from jungle areas, and 3 from the swampy northern coast of Peru. The patients had 1-5 lesions, most of which were on the lower extremities. One patient had 5 clustered gluteal lesions; another patient had 2 lesions on a finger. Three patients were lost to follow-up. All 5 remaining patients had moderate disease. Diverse treatments (antituberculous drugs, World Health Organization [WHO] recommended antimicrobial drug treatment for BU, and for 3 patients, excision surgery) were successful. Only 1 patient (patient 7) received the specific drug treatment recommended by WHO. BU is endemic in Peru, although apparently infrequent. Education of populations and training of health workers are first needed to evaluate and understand the full extent of BU in Peru.

Haplotype and gene network analyses were performed on mitochondrial cytochrome oxidase I and cytochrome b gene sequences of Lutzomyia (Lu.) ayacuchensis populations from Andean areas of Ecuador and southern Peru where the sand fly species transmit Leishmania (Leishmania) mexicana and Leishmania (Viannia) peruviana, respectively, and populations from the northern Peruvian Andes, for which transmission of Leishmania by Lu. ayacuchensis has not been reported. The haplotype analyses showed higher intrapopulation genetic divergence in northern Peruvian Andes populations and less divergence in the southern Peru and Ecuador populations, suggesting that a population bottleneck occurred in the latter populations, but not in former ones. Importantly, both haplotype and phylogenetic analyses showed that populations from Ecuador consisted of clearly distinct clusters from southern Peru, and the two populations were separated from those of northern Peru.

Early Pottery Making in Northern Coastal Peru. Part I: Moessbauer Study of Clays
International Nuclear Information System (INIS)
Shimada, I.; Haeusler, W.; Hutzelmann, T.; Wagner, U.
2003-01-01
We report on an investigation of several ancient clays which were used for pottery making in northern coastal Peru at a kiln site from the Formative period (ca. 2000-800 BC) in the Poma Canal and at a Middle Sican pottery workshop in use between ca. AD 950 and 1050 at Huaca Sialupe in the lower La Leche valley. Neutron activation analysis, 57 Fe Moessbauer spectroscopy and X-ray diffraction were used for the characterisation of the clays. The changes that occur in iron-bearing compounds in the clays depending on the kiln atmosphere and on the maximum firing temperature were studied by Moessbauer spectroscopy and X-ray diffraction. Laboratory firing series under varying controlled conditions were performed to obtain a basic understanding of the different reactions taking place in the clays during firing. The results can be used as models in the interpretation of the Moessbauer spectra observed in ancient ceramics from the same context.

We present data from three seasons of experimental field work designed to recreate ancient Andean coastal ceramic firing techniques. Based on the recent discovery of two different archaeological ceramic production sites in the La Leche river valley of northern coastal Peru, the opportunity arose to apply Moessbauer spectroscopy and other analytical methods to reconstruct ancient firing procedures. Two sets of firings took place in 1993 and 1997 in Batan Grande using a partially restored Formative kiln from about 800 BC, local hardwood and cow dung as fuel. A third experiment followed in 2000 after the discovery of a Middle Sican ceramics workshop in use between ca. AD 950 and 1050 at Huaca Sialupe, where an exact replica of an ancient kiln was built from local clay, and fired with local wood and cow dung. Additionally, inverted urns found at Huaca Sialupe were tested for their potential use as furnaces for metal working. Moessbauer spectroscopy was used to compare the physical and chemical state of specimens produced in the field experiments with ancient ceramics and with specimens produced in controlled laboratory experiments.

For at least 6 m.y., El Niño events have posed the greatest environmental risk on the Peruvian coast. A better understanding of El Niño is essential for predicting future risk and growth in this tropical desert. To achieve this we analyzed archaeological and modern pre-bomb shells from the surf clam Donax for the radiocarbon reservoir effect (ΔR) to characterize late Holocene coastal upwelling conditions in northern Peru (8°14′S). Mean ΔR values from these shells suggest that modern upwelling conditions in this region were likely established between A.D. 539 and A.D. 1578. Our radiocarbon data suggest that upwelling conditions ca. A.D. 539 were less intense than those in modern times. The observed coastal water enrichment in 14C may be consequence of frequent strong El Niño events or extended El Niño–like conditions. These ΔR-inferred marine conditions are in agreement with proposed extended El Niño activity in proxy and archaeological records of ca. A.D. 475–530. Extended El Niño conditions have been linked to political destabilization, societal transformation, and collapse of the Moche civilization in northern Peru. A return to such conditions would have significant impacts on the dense population of this region today and in the near future.

Short report: serologic evidence of human ehrlichiosis in Peru.
Moro, Pedro L; Shah, Jyotsna; Li, Olga; Gilman, Robert H; Harris, Nick; Moro, Manuel H
2009-02-01
A serosurvey for human ehrlichiosis caused by Ehrlichia chaffeensis and Anaplasma phagocytophilum was performed in different regions of Peru by using indirect immunofluorescence assays (IFAs). Regions included an urban community in a shantytown in Lima (Pampas) and three rural communities located on the northern coast of Peru (Cura Mori), in the southern Peruvian Andes (Cochapata), and in the Peruvian jungle region (Santo Tomas). An overall E. chaffeensis seroprevalence of 13% (21 of 160) was found by IFA. Seroprevalences in females and males was 15% (16 of 106) and 9% (5 of 53), respectively. Seroprevalences in Cura Mori, Cochapata, Pampas, and Santo Tomas were 25% (10 of 40), 23% (9 of 40), 3% (1 of 40), and 3% (1 of 40), respectively. Seroprevalences in Cura Mori and Cochapata were significantly higher than in Santo Tomas or Pampas (P Peru. Further studies are needed to characterize Ehrlichia species in Peru, their vectors and their clinical significance.

2015-01-01
We report a cluster of imported vivax malaria in three of five Chilean travelers returning from Peru in March 2015. The cluster highlights the high risk of malaria in the Loreto region in northern Peru, which includes popular destinations for international nature and adventure tourism. According to local surveillance data, Plasmodium vivax is predominating, but Plasmodium falciparum is also present, and the incidence of both species has increased during recent years. Travelers visiting this region should be counseled about the prevention of malaria and the options for chemoprophylaxis. © 2015 International Society of Travel Medicine.

Taeniasis and cysticercosis are major causes of seizures and epilepsy. Infection by the causative parasite Taenia solium requires transmission between humans and pigs. The disease is considered to be eradicable, but data on attempts at regional elimination are lacking. We conducted a three-phase control program in Tumbes, Peru, to determine whether regional elimination would be feasible. We systematically tested and compared elimination strategies to show the feasibility of interrupting the transmission of T. solium infection in a region of highly endemic disease in Peru. In phase 1, we assessed the effectiveness and feasibility of six intervention strategies that involved screening of humans and pigs, antiparasitic treatment, prevention education, and pig replacement in 42 villages. In phase 2, we compared mass treatment with mass screening (each either with or without vaccination of pigs) in 17 villages. In phase 3, we implemented the final strategy of mass treatment of humans along with the mass treatment and vaccination of pigs in the entire rural region of Tumbes (107 villages comprising 81,170 people and 55,638 pigs). The effect of the intervention was measured after phases 2 and 3 with the use of detailed necropsy to detect pigs with live, nondegenerated cysts capable of causing new infection. The necropsy sampling was weighted in that we preferentially included more samples from seropositive pigs than from seronegative pigs. Only two of the strategies implemented in phase 1 resulted in limited control over the transmission of T. solium infection, which highlighted the need to intensify the subsequent strategies. After the strategies in phase 2 were implemented, no cyst that was capable of further transmission of T. solium infection was found among 658 sampled pigs. One year later, without further intervention, 7 of 310 sampled pigs had live, nondegenerated cysts, but no infected pig was found in 11 of 17 villages, including all the villages in which mass

[Update on tegumentary leishmaniasis and carrion's disease vectors in Peru].
Zorrilla, Victor; Vásquez, Gissella; Espada, Liz; Ramírez, Pablo
2017-01-01
Among approximately 190 species of Lutzomyia in Peru, only a small number have been identified as vectors of tegumentary leishmaniasis in Western and inter-Andean valleys. These include L. peruensis, L. verrucarum, L. tejadai, L. ayacuchensis, and L. pescei. In the Amazon region, L. yuilli yuilli, L. chagasi, L. davisi, and L. auraensis are naturally infected, among the subgenera Leishmania and Viannia. L. auraensis is newly reported as a potential vector of leishmaniasis in neotropical regions. Among the primary and most widely distributed vectors of human bartonellosis or Carrión's disease, L. verrucarum and L. peruensis are predominant in the Andean regions of northern, central, and southern Peru. Other potential vectors of Carrion's disease are L. serrana in the Monzon Valley, Huamalies, and Huanuco; L. pescei in Apurímac and Cusco; and L. robusta and L. maranonensis in Jaén, San Ignacio, and Utcubamba provinces, and the high forests of Peru. Because of the high prevalence of leishmaniasis and bartonellosis outside of known endemic areas in Peru, it is necessary to update data and distribution maps of these disease vectors. This may improve both prevention and control measures. Existing information about sandfly vectors in Peru is also provided in this article.

Radiometric dating of the extinction of the large Pleistocene fauna in Peru
International Nuclear Information System (INIS)
Falgueres, C.; Fontugne, M.
1994-01-01
The discovery in northern Peru of fossil deposits belonging to large mammals allows the dating of the extinction of this fauna. The method based on disequilibrium within the uranium family ( 230 Th/ 234 U) was used. The extinction occurred at the end of the Pleistocene and is contemporaneous with the beginning of the deglaciation. Moreover, this dating, compared with results of excavations of palaeo-indian ''Paijan'' sites, indicates that human groups in Peru did not play a significant role in extinction of this large fauna.

Rapid subduction of the Nazca plate beneath the northen Andes margin (~6 cm/yr) results in two different processes: (1) elastic stress is accumulating along the Nazca/South American plate interface which is responsible for one of the largest megathrust earthquake sequences during the last century. The 500-km-long rupture zone of the 1906 (Mw= 8.8) event was partially reactivated by three events from the 1942 (Mw = 7.8), 1958 (Mw = 7.7), to the 1979 (Mw = 8.2). However, south of latitude 1°S, no M>8 earthquake has been reported in the last three centuries, suggesting that this area is slipping aseismically (2) permanent deformation causes opening of the Gulf of Guayaquil, with northeastwards motion of the Northern Andean Block (NAB). We present a new GPS velocity field covering the northern Andes from south of the Gulf of Guayaquil to the Caribbean plate. Our velocity field includes new continuously-recording GPS stations installed along the Ecuadorian coast, together with campaign sites observed since 1994 in the CASA project (Kellogg et al., 1989). We first estimate the long-term kinematics of the NAB in a joint inversion including GPS data, earthquake slip vectors, and quaternary slip rates on major faults. The inversion provides an Euler pole located at long. -107.8°E, lat. 36.2°N, 0.091°/Ma and indicates little internal deformation of the NAB (wrms=1.2 mm/yr). As a consequence, 30% of the obliquity of the Nazca/South America motion is accommodated by transcurrent to transpressive motion along the eastern boundary of the NAB. Residual velocities with respect to the NAB are then modeled in terms Models indicate a patchwork of highly coupled asperities encompassed by aseismic patches over the area of rupture of the M~8.8 1906 earthquake. Very low coupling is found along the southern Ecuadorian and northern Peru subduction.

Climate conditions of the “El Niño” phenomenon for a hydro-eolic complementarity project in peru
Castillo N, Leonardo; Ortega M, Arturo; Luyo, Jaime E.
2018-05-01
Northern Peru is threatened by the consequences of a natural phenomenon called “El Niño”, mainly during the months of December to April. In the summer of 2017, this event reported strong climatic variations with intense rains, increasing the water levels of the Chira and Piura rivers, filling the Poechos reservoir, together with flooding and mudding. However, from an energetic perspective, these climatic alterations have a strong potential to increase the availability of the wind and hydro renewable energies in northern Peru. This work performs an evaluation of the hydro-eolic complementarity as part of the sustainability of energy systems. The study includes evaluation of historical records of wind velocity and water flow rates. It then evaluates correlation, analysis, and estimates the hydro and wind energy potentials generated by this phenomenon. The implications of the "El Niño" phenomenon are mostly negative. Nonetheless, it is possible to take advantage of higher wind and water flow rates with a hybrid energy system. The results obtained show a high degree of complementarity both normal and "El Niño" phenomenon condition in northern Peru.

This publication provides a brief account of Peru's geographic, history, government, and political and economic conditions. With an area of 1.28 million sq. km., Peru is the third largest country in South American and is home to 20.2 million inhabitants (6 million live in the capital city of Lima). The population is 45% Indian, 37% mestizo, 15% white, and 3% black, Asian, and other. The 2 official languages are Spanish and Quechua. Its literacy rate stands at 79%, and its infant mortality rate and life expectancy measure 91/1000 and 60.8 years respectively. Peru's pre-Colombian period notes the impressive achievements of the Inca civilization, which was conquered by Spain in 1531. The country gained its independence from Spanish rule in 1821. The article also mentions Peru's turbulent contemporary history, with territorial disputes, a strong military presence, and a series of coups that have interrupted civilian constitutional governments. As recently as 1985, Peru had its first exchange of power from 1 democratically elected leader to another in 40 years, when 36 year-old Alan Garcia Perez became president. Leader of the American Popular Revolutionary Alliance (APRA), GArcia espouses leftist but not non-communist politics, and is well-known for his message of anti-imperialism and Latin American integration. Peru's has seen terrorist activity from 2 marxist organizations, the Maoist Sendero Luminoso (The Shining Path) and the MRTA-MIR (Tupac Amaru Revolutionary Movement-Movement of the Revolutionary Left. In 1986, Peru's economy had a $17 billion Gross Domestic Product (GDP), a per capital GDP of $839, and an inflation rate of 62.9. The article also provides information concerning US economic assistance to Peru, as well as an assessment of US-Peruvian relations.

Geologic Water Storage in Pre-Columbian Peru
Energy Technology Data Exchange (ETDEWEB)
Fairley Jr., Jerry P.
1997-07-14
Agriculture in the arid and semi-arid regions that comprise much of present-day Peru, Bolivia, and Northern Chile is heavily dependent on irrigation; however, obtaining a dependable water supply in these areas is often difficult. The precolumbian peoples of Andean South America adapted to this situation by devising many strategies for transporting, storing, and retrieving water to insure consistent supply. I propose that the ''elaborated springs'' found at several Inka sites near Cuzco, Peru, are the visible expression of a simple and effective system of groundwater control and storage. I call this system ''geologic water storage'' because the water is stored in the pore spaces of sands, soils, and other near-surface geologic materials. I present two examples of sites in the Cuzco area that use this technology (Tambomachay and Tipon) and discuss the potential for identification of similar systems developed by other ancient Latin American cultures.

An extensive geochemical data set from the northern Peninsular Ranges Batholith (PRB) in southern California is compared and contrasted with the Arequipa segment of the Peruvian Coastal Batholith, including new granitoid samples recently collected near Ica (14°S, 76°W). The data include major and trace elements and Sr isotope ratios. This is part of an on-going study of subduction-related magmatism to refine a petrogenetic model of crust formation at plate boundaries, with a particular interest in the role of magma mixing. Research in the northern PRB suggests that continental crust is formed in several cycles: (1) mantle melting to give mafic volcanics and gabbroic intrusives, (2) basalt/gabbro melting to give felsic granitoids uncontaminated by continental crust and having low initial 87Sr/86Sr (Sri) values less than 0.704, and (3) crustal melting to give high Sri values greater than 0.704. Geochemical evidence was used to determine the extent of mixing between mafic and felsic magma that produced rocks of intermediate SiO2 composition. These differentiation cycles formed a west to east chronologic sequence and yielded granitoids of gabbro, tonalite, and granodiorite composition. Using principal component analysis on the northern PRB granitoids, the four factors affecting geochemical composition were categorized as differentiation, crustal contamination, depth of magma source, and conditions that yield a range from calcic to more alkaline granitoids. A similar major and trace element analysis is being done for a classic result of subduction in the Peruvian Coastal Batholith. The Peruvian samples recently collected include granitoids of the upper Cretaceous Coastal Batholith, as well as the associated volcanics of Cretaceous and Jurassic age. The Coastal Batholith samples include a range of granitoids from the early gabbros and from the four batholithic super-units (from west to east: Linga, Pampahuasi, Tiabaya, and Incahuasi) containing a combination of diorite

EXPERIMENTAL STUDIES ON YELLOW FEVER IN NORTHERN PERU.
Noguchi, H; Kligler, I J
1921-01-31
Fourteen typical cases of yellow fever were studied in northern Peru during an epidemic occurring in 1920, nine in Payta in March and April, and five in Morropon and Piura in April and May. The method of investigation was similar to that previously employed, but as the laboratory facilities were very meager certain changes were required. Although in Payta the work was handicapped by the lack of electric light, the scarcity of water and animal food, the unsuitability of the guinea pigs for inoculation, and the changes in culture media due to age, the results obtained under these adverse conditions were by no means negative. While in no instance was there a typical infection produced in animals, either by direct inoculation of blood or with culture materials, yet certain guinea pigs in each series showed temporary febrile reactions or definite hemorrhagic lesions of the lungs indicative of a mild leptospira infection. Direct search for Leptospira icteroides in the blood of patients or in culture materials was not made because the dark-field microscope could not be used. Subsequently, at Piura, the laboratory facilities were vastly, improved, the use of the dark-field microscope was made possible by means of a storage battery, and a fresh stock of young healthy guinea pigs was received from New York, and fresh rabbit serum obtained in Piura. In the study of the materials obtained from five cases of yellow fever in Morropon all these added facilities were taken advantage of, with the result that the outcome was positive and convincing. Cultures from the five cases were examined after 11, 12, and 13 days, and in those from three cases living leptospiras were found. By inoculation into suitable guinea pigs of culture material from these five cases, irrespective of whether or not leptospiras were detected under the dark-field microscope, a typical Leptospira icteroides infection was produced from four of the five cases. In one of these no leptospira had been detected in

ENSO impact on hydrology in Peru
Lavado-Casimiro, W. S.; Felipe, O.; Silvestre, E.; Bourrel, L.
2013-04-01
The El Niño and La Niña impacts on the hydrology of Peru were assessed based on discharge data (1968-2006) of 20 river catchments distributed over three drainage regions in Peru: 14 in the Pacific Coast (PC), 3 in the Lake Titicaca (TL) region, and 3 in the Amazonas (AM). To classify the El Niño and La Niña events, we used the Southern Oscillation Index (SOI) based on hydrological years (September to August). Using the SOI values, the events were re-classified as strong El Niño (SEN), moderate El Niño (MEN), normal years (N), moderate La Niña (MLN) and strong La Niña (SLN). On average during the SEN years, sharp increases occurred in the discharges in the north central area of the PC and decreases in the remaining discharge stations that were analyzed, while in the years of MEN events, these changes show different responses than those of the SEN. During the years classified as La Niña, positive changes are mostly observed in the majority of the stations in the rivers located in the center of Peru's Pacific Coast. Another important result of this work is that the Ilave River (south of the Titicaca watershed) shows higher positive (negative) impacts during La Niña (El Niño) years, a fact that is not clearly seen in the rivers of the northern part of the Titicaca watershed (Ramis and Huancane rivers).

Natural gas distribution network of Lima and Callao, Peru
Energy Technology Data Exchange (ETDEWEB)
Maroye, Stephane; Aerssens, Andre [Tractebel Engineering, Lima (Peru)
2005-07-01
In May 2002, Suez-Tractebel was awarded by the government of Peru a 30-year concession for the construction and operation of the gas distribution network in Lima, Peru. On 10 July, 2004, first gas was delivered to Lima, 1 month ahead of the official date. This gas distribution network, operated by GNLC (Gas Natural de Lima y Callao), delivers gas to some of the largest industries and power generators in and around Lima and the harbour area of Callao. Gas delivered in Lima comes through a 700 km HP gas pipeline from Camisea fields. This pipeline is operated by TGP (Transportadora de Gas del Peru). A City Gate is located at Lurin, on the southern side of the city. The gas distribution network is made of a 62 km main pipeline (20') with 25 km laterals. The main pipeline is operated at 50 bar, as the main customer, the Etevensa power plant, is located on the northern side of the city. Due to this high operating pressure combined to the surroundings, specific design philosophies were adopted to meet the extreme safety requirements. This paper highlights the specific measures taken during construction phase and the experience of the first months of operation of this challenging project. (author)

Effect of the Spanish Conquest on coastal change in Northwestern Peru
Belknap, Daniel F.; Sandweiss, Daniel H.
2014-06-01
When Francisco Pizarro and his small band of Spanish conquistadores landed in northern Peru in A.D. 1532 to begin their conquest of the vast Inca Empire, they initiated profound changes in the culture, language, technology, economics, and demography of western South America. They also altered anthropogenically modulated processes of shoreline change that had functioned for millennia. Beginning with the extirpation of local cultures as a result of the Spanish Conquest, and continuing through today, the intersection of demography, economy, and El Niño-driven beach-ridge formation on the Chira beach-ridge plain of Northwestern Peru has changed the nature of coastal evolution in this region. A similar event may have occurred at about 2800 calibrated y B.P. in association with increased El Niño frequency.

Crustal structure of north Peru from analysis of teleseismic receiver functions
Condori, Cristobal; França, George S.; Tavera, Hernando J.; Albuquerque, Diogo F.; Bishop, Brandon T.; Beck, Susan L.
2017-07-01
In this study, we present results from teleseismic receiver functions, in order to investigate the crustal thickness and Vp/Vs ratio beneath northern Peru. A total number of 981 receiver functions were analyzed, from data recorded by 28 broadband seismic stations from the Peruvian permanent seismic network, the regional temporary SisNort network and one CTBTO station. The Moho depth and average crustal Vp/Vs ratio were determined at each station using the H-k stacking technique to identify the arrival times of primary P to S conversion and crustal reverberations (PpPms, PpSs + PsPms). The results show that the Moho depth correlates well with the surface topography and varies significantly from west to east, showing a shallow depth of around 25 km near the coast, a maximum depth of 55-60 km beneath the Andean Cordillera, and a depth of 35-40 km further to the east in the Amazonian Basin. The bulk crustal Vp/Vs ratio ranges between 1.60 and 1.88 with the mean of 1.75. Higher values between 1.75 and 1.88 are found beneath the Eastern and Western Cordilleras, consistent with a mafic composition in the lower crust. In contrast values vary from 1.60 to 1.75 in the extreme flanks of the Eastern and Western Cordillera indicating a felsic composition. We find a positive relationship between crustal thickness, Vp/Vs ratio, the Bouguer anomaly, and topography. These results are consistent with previous studies in other parts of Peru (central and southern regions) and provide the first crustal thickness estimates for the high cordillera in northern Peru.

El Dorado : Peru is trying to catch Colombia as the must go jurisdiction in South America
International Nuclear Information System (INIS)
Stastny, R.P.
2010-01-01
Peru has vast and largely untapped reserves of crude and natural gas, but it wants foreign help to increase oil production to 500,000 barrels per day in 4 years from the current level of 140,000 barrels per day. Perupetro is a state company in Peru responsible for promoting investment in the petroleum sector. Peru hopes to lure nearly $2 billion in oil investment to its northern Amazon region through 2013. Companies operating in South America have been attracted to Peru in recent years by its exploration potential and one of the best fiscal regimes in the world, at a 5 percent minimum royalty and a 20 percent maximum royalty. However, the government has changed the rules for the blocks offered in the 2010 bid process, increasing the minimum royalty to 15 percent and the maximum to 35 percent. The intent was to bring the higher royalties more in line with Colombia's. However, some analysts claim that Peru lacks the critical mass to justify the increase in royalties. Other challenges facing resource development in Peru include lack of infrastructure and a slow regulatory system. Twenty-five blocks of land are up for bid in 2010, mostly early stage properties. The bidding process will indicate how companies will respond to the new economics of these blocks. 1 tab.

The variability of radiocarbon marine reservoir age through time and space limits the accuracy of chronologies in marine paleo-environmental archives. We report here new radiocarbon reservoir ages (ΔR) from the central coast of Chile ( 32°S) for the Holocene period and compare these values to existing reservoir age reconstructions from southern Peru and northern Chile. Late Holocene ΔR values show little variability from central Chile to Peru. Prior to 6000 cal yr BP, however, ΔR values were markedly increased in southern Peru and northern Chile, while similar or slightly lower-than-modern ΔR values were observed in central Chile. This extended dataset suggests that the early Holocene was characterized by a substantial increase in the latitudinal gradient of marine reservoir age between central and northern Chile. This change in the marine reservoir ages indicates that the early Holocene air-sea flux of CO2 could have been up to five times more intense than in the late Holocene in the Peruvian upwelling, while slightly reduced in central Chile. Our results show that oceanic circulation changes in the Humboldt system during the Holocene have substantially modified the air-sea carbon flux in this region.

An alluvial record of El Niño events from northern coastal Peru
Wells, Lisa E.
1987-12-01
Overbank flood deposits of northern coastal Peru provide the potential for the development of a late Quaternary chronology of El Niño events. Alluvial deposits from the 1982-1983 El Niño event are the basis for establishing a type El Niño deposit. Sedimentary structures suggesting depositional processes range from sheet flows to debris flows, with sheet flood deposits being the most common. The 1982-1983 deposits are characterized by a 50- to 100-cm- thick basal gravel, overlain by a 10- to 100-cm-thick sand bed, grading into a 1- to 10-cm-thick silty sand bed and capped by a very thin layer of silt or clay. The surface of the deposit commonly displays the original shear flow lines crosscut by postdepositional mud cracks and footprints (human and animal). Stacked sequences of flood deposits are present in Pleistocene and Holocene alluvial fill, suggesting that El Niño type events likely occurred throughout the late Quaternary. A relative chronology of the deposits is developed based on terrace and soil stratigraphy and on the degree of preservation of surficial features. A minimum of 15 El Niño events occurred during the Holocene; a minimum of 21 events occurred during the late Pleistocene. Timing of the Holocene events is bracketed by isochrons derived from the archaeologic stratigraphy. Corrected radiocarbon ages from included detrital wood provide the following absolute dates for El Niño events: 1720 ± 60 A.D., 1460 ± 20 A.D., 1380 ± 140 A.D. (error overlaps with the A.D. 1460 event; these may represent a single event), and 1230 ± 60 B.C.

Two major domestic terrorist groups have plagued Peru over the past 20 years, the Sendero Luminoso or "Shining Path" (SL) and the Revolutionary Movement Túpac Amaru (MRTA). On 28 August 2003, the Peruvian Truth and Reconciliation Commission reported that an estimated 69,280 persons were killed in the internal conflict in Peru from 1980 to 2000. Most of the victims were farmers (56%), most attacks occurred in rural settings (79%), and the SL was responsible for most of the deaths (54%). Aggressive anti-terrorism efforts by police and military during this period, often at the expense of basic human rights, also contributed to this large burden of terrorism on Peru. During the 1990s, terrorist attacks in Peru had spread to its urban areas. On 17 December 1996, 22 members of MRTA took over the Japanese ambassador's residence in Lima, holding 72 hostages until the grounds were stormed by Peruvian special forces on 23 April 1997. Until recently, emergency planning and preparedness for terrorism-related events in Peru were largely underdeveloped. In the last five years, Peru has taken two key steps towards developing a mature emergency response system, with the establishment of the country's first emergency medicine residency training program and the construction of the first dedicated trauma center in Lima.

Characteristics and origin of rock varnish from the hyperarid coastal deserts of northern Peru
Jones, Charles E.
1991-01-01
The characteristics of a new type of rock varnish from the hyperarid coastal deserts of northern Peru, combined with laboratory experiments on associated soil materials, provide new insights into the formation of rock varnish. The Peruvian varnish consists of an Fe-rich, Mn-poor component covering up to 95% of a varnished surface and a Fe-rich, Mn-rich component found only in pits and along cracks and ridges. The alkaline soils plus the catalytic Fe oxyhydroxides that coat much of the varnish surfaces make the Peruvian situation ideal for physicochemical precipitation of Mn. However, the low Mn content of the dominant Fe-rich, Mn-poor component suggests that such precipitation is minor. This, plus the presence of abundant bacteria in the Mn-rich varnish and the recorded presence of Mn-precipitating bacteria in varnish elsewhere, suggests that bacteria are almost solely responsible for Mn-precipitation in rock varnish. A set of experiments involving Peruvian soil samples in contact with water-CO 2 solutions indicates that natural fogs or dews release Mn but not Fe when they come in contact with eolian materials on rock surfaces. This mechanism may efficiently provide Mn to bacteria on varnishing surfaces. The lack of Fe in solution suggests that a large but unknown proportion of Fe in varnish may be in the form of insoluble Fe oxyhydroxides sorbed onto the clay minerals that form the bulk of rock varnish. The results of this study do not substantively change R. I. Dorn's paleoenvironmental interpretations of varnish Mn:Fe ratios, but they do suggest areas for further inquiry.

Large slope instabilities in Northern Chile and Southern Peru
Crosta, Giovanni B.; Hermanns, Reginald L.; Valbuzzi, Elena; Frattini, Paolo; Valagussa, Andrea
2014-05-01
Deep canyon incision into Tertiary paleosurfaces and large slope instabilities along the canyon flanks characterize the landscape of western slope of the Andes of northern Chile and South Peru. This area belongs to the Coastal Escarpment and Precordillera and is formed by coarse-grained clastic and volcanoclastic formations. The area is characterized by intense seismicity and long-term hyperaridity (Atacama Desert). Landslides along the canyon flanks affect volumes generally up to 1 km3 and locally evolved in large rock avalanches. We prepared a landslide inventory covering an area of about 30,000 km2, extending from Iquique (Chile) to the South and Tacna (Peru) to the North. A total of 606 landslides have been mapped in the area by use of satellite images and direct field surveys, prevalently including large phenomena. The landslides range from 1 10-3 km2 to 464 km2 (Lluta landslide). The total landslide area, inclusive of the landslide scarp and of the deposit, amounts to about 2,130 km2 (about 7% of the area). The mega landslides can be classified as large block slides that can evolve in large rock avalanches (e.g. Minimini landslide). Their initiation seems to be strongly associated to the presence of secondary faults and large fractures transversal to the slope. These landslides show evidence suggesting a re-incision by the main canyon network. This seems particularly true for the Lluta collapse where the main 'landslide' mass is masked or deleted by the successive erosion. Other landslides have been mapped along the Coastal Escarpment and some of the major tectonic escarpments with an E-W trend. We examined area-frequency distributions of landslides by developing logarithmically binned, non-cumulative size frequency distributions that report frequency density as a function of landslide planar area A. The size frequency distribution presents a strong undersampling for smaller landslides, due to the extremely old age of the inventory. For landslides larger than

Seroprevalence of hepatitis C antibody in Peru.
Hyams, K C; Phillips, I A; Moran, A Y; Tejada, A; Wignall, F S; Escamilla, J
1992-06-01
The prevalence in Peru of antibody to hepatitis C virus (anti-HCV) was determined in a survey of populations living in the northern jungle region and in groups at high risk of parenterally and sexually transmitted diseases. All sera were initially screened for anti-HCV using commercial first and second generation ELISAs; repeatedly reactive sera were further verified with a second generation immunoblot assay. Serum samples were also tested by ELISA for HBsAg, anti-HBs, and anti-HBc. None of 2,111 sera obtained in the survey of jungle residents was positive for anti-HCV by immunoblot assay. Twelve of 16 HIV-1 antibody positive hemophiliacs, one of 103 HIV-1 antibody positive homosexuals, and three of 602 HIV-1 negative registered female prostitutes were positive for anti-HCV. A high prevalence of total markers of hepatitis B infection was found in all subjects, especially in older subjects and groups at high risk of parenterally and sexually transmitted diseases. The findings of this study indicate that seropositivity for hepatitis C virus antibody is uncommon in Peru except in high risk groups and suggest that the epidemiology of hepatitis C differs substantially from hepatitis B.

Hymenolepis nana , the dwarf tapeworm, is a common intestinal infection of children worldwide. We evaluated infection and risk factor data that were previously collected from 14,761 children aged 2-15 years during a large-scale program in northern Peru. We found that 1,124 of 14,761 children (7.61%) had H. nana infection, a likely underestimate given that only a single stool sample was examined by microscopy for diagnosis. The strongest association with infection was lack of adequate water (adjusted prevalence ratio [aPR] 2.22, 95% confidence interval [CI] 1.82-2.48) and sanitation infrastructure in the house (aPR 1.94, 95% CI 1.64-2.29). One quarter of those tested did not have a bathroom or latrine at home, which doubled their likelihood of infection. Similarly, one quarter did not have piped public water to the house, which also increased the likelihood of infection. Continued efforts to improve access to basic water and sanitation services will likely reduce the burden of infection in children for this and other intestinal infections.

Full Text Available Objectives: To identify the prevalence and factors associated with fragility syndrome in older adults attending the EsSalud (Peruvian Social Security Health Insurance primary health care service, Chiclayo - Peru. Materials and methods: A descriptive, prospective and cross-sectional study was conducted on a sample consisting of 326 older adults from urban areas and surrounding districts of Chiclayo, who attend the outpatient service at the Hospital Naylamp and Policlínico Chiclayo Oeste. A data collection sheet including social-demographic variables, comorbidity and polypharmacy, and fragility syndrome clinical criteria was filled in. Results: The prevalence of fragility was 17.5% and that of pre-fragility, 40.9%. The most frequent fragility clinical criteria were as follows: self-reported fatigue (42.3% and decreased grip strength (32.8%. The bivariate analysis showed an association with age, level of education, occupation (class IV and V concerning manual work, comorbidity (class II, asymptomatic disease or asymptomatic disease that requires medication but is under control, polypharmacy, anemia, Parkinson’s disease and non-vascular neurological disease. The final prediction model covering the age (1.08, 95% CI: 1.03 to 1.12, higher education level as a preventive variable (0.21, 95% CI: 0.07 to 0.62, type II comorbidity (11 08, 95% CI: 1.45 to 84.38 and polypharmacy (2.49, 95% CI: 1.24 to 5.03 predicts the likelihood of fragility syndrome in 75.6%.

This paper provides information about Peru's dental history and dental school system, including the curriculum and dental licensure. With the increase in the number of dental schools in Peru, the number of dentists is also increasing. Until 1965, Peru had only three dental schools; currently, there are 14. Four of these dental schools are public, and ten are private. A five- or six-year dental program leads to the B.D.S. degree. After successful completion of a thesis defense or competency examination, the D.D.S. degree is awarded. The D.D.S. is mandatory for practicing dentistry in Peru. Currently, there are approximately 14,000 active dentists, with a dentist-patient ratio of approximately 1:2,000.

Clinanthus milagroanthus S. Leiva & Meerow, sp. nov. is described from the Department of La Libertad in Peru. The new species is most closely related to Clinanthus mirabilis (Ravenna) Meerow, with further affinities to Clinanthus viridiflorus (R. & P.) Meerow. It can be distinguished from Clinanthus mirabilis by its wider leaves, the much more brightly colored and wide spreading limb, and the much lighter colored perigone tube (yellowish green vs. dark green in Clinanthus mirabilis). A conspicuous bulge just proximal to the midpoint of the tube is a unique character of the new species.

Anopheline specimens were collected in 2011 by human landing catch, Shannon and CDC traps from the malaria endemic localities of Santa Rosa and San Pedro in Madre de Dios Department, Peru. Most specimens were either Anopheles (Nyssorhynchus) benarrochi B or An. (Nys.) rangeli, confirmed by polymerase chain reaction-restriction fragment length polymorphism-internal transcribed spacer 2 (PCR-RFLP-ITS2) and, for selected individuals, ITS2 sequences. A few specimens from Lupuna, Loreto Department, northern Amazonian Peru, were also identified as An. benarrochi B. A statistical parsimony network using ITS2 sequences confirmed that all Peruvian An. benarrochi B analyzed were identical to those in GenBank from Putumayo, southern Colombia. Sequences of the mtDNA COI BOLD region of specimens from all three Peruvian localities were connected using a statistical parsimony network, although there were multiple mutation steps between northern and southern Peruvian sequences. A Bayesian inference of concatenated Peruvian sequences of ITS2+COI detected a single clade with very high support for all An. benarrochi B except one individual from Lupuna that was excluded. No samples were positive for Plasmodium by CytB-PCR. PMID:23243107

Peru Brand: a Nation under Construction?
Elder Cuevas-Calderón
2016-01-01
During the last decade Peru has experienced a euphoric rediscovery –pseudo revaluation as a country– due to its booming gastronomy, tourism and economic growth.In this context, the presentresearch uses semio-psychoanalytic and postcolonial theories to explain Peru’s social outlook regarding the concept of nation, its reunion with a non-existent identity and the construction of the idea of nation based on the marketing campaign titled the Peru Brand. Thus, Peru Brand, far from uniting all Peru...

Plausible worst-case tsunamigenic scenarios definition plays a relevant role in tsunami hazard assessment focused in emergency preparedness and evacuation planning for coastal communities. During the last decade, the occurrence of major and moderate tsunamigenic earthquakes along worldwide subduction zones has given clues about critical parameters involved in near-field tsunami inundation processes, i.e. slip spatial distribution, shelf resonance of edge waves and local geomorphology effects. To analyze the effects of these seismic and hydrodynamic variables over the epistemic uncertainty of coastal inundation, we implement a combined methodology using deterministic and probabilistic approaches to construct 420 tsunamigenic scenarios in a mature seismic gap of southern Peru and northern Chile, extended from 17ºS to 24ºS. The deterministic scenarios are calculated using a regional distribution of trench-parallel gravity anomaly (TPGA) and trench-parallel topography anomaly (TPTA), three-dimensional Slab 1.0 worldwide subduction zones geometry model and published interseismic coupling (ISC) distributions. As result, we find four higher slip deficit zones interpreted as major seismic asperities of the gap, used in a hierarchical tree scheme to generate ten tsunamigenic scenarios with seismic magnitudes fluctuates between Mw 8.4 to Mw 8.9. Additionally, we construct ten homogeneous slip scenarios as inundation baseline. For the probabilistic approach, we implement a Karhunen - Loève expansion to generate 400 stochastic tsunamigenic scenarios over the maximum extension of the gap, with the same magnitude range of the deterministic sources. All the scenarios are simulated through a non-hydrostatic tsunami model Neowave 2D, using a classical nesting scheme, for five coastal major cities in northern Chile (Arica, Iquique, Tocopilla, Mejillones and Antofagasta) obtaining high resolution data of inundation depth, runup, coastal currents and sea level elevation.

Foreign oil companies weathering Peru's political crisis
International Nuclear Information System (INIS)
Anon.
1992-01-01
This paper reports that foreign oil companies are weathering Peru's political crisis, and the outlook for increased foreign participation in Peru's petroleum sector remains promising. There has been improvement in the political turmoil and soured international relations that followed President Alberto Fujimori's Apr. 5 suspension of Peru's Congress, charging political corruption and attempts to block his fiscal reforms. But there are fresh concerns over an increase in terrorism aimed at oil industry facilities by antigovernment guerrilla groups in Peru. Meanwhile, state-owned oil company Petroleos del Peru (Petroperu) continues efforts to sell assets as part of Fujimori's mandated privatization program. And foreign companies continue to grapple with uncertainty and bureaucratic red tape in chasing investment opportunities in Peru's beleaguered but opening petroleum sector

Tectonic subsidence analyses of miogeoclinal strata from mesozoic marginal basin of Peru
Energy Technology Data Exchange (ETDEWEB)
Devlin, W.J.
1988-01-01
The Western Peruvian trough is composed of an eastern miogeoclinical facies of carbonate and clastic strata, and a western eugeoclinal facies consisting of a succession of volcanic and sedimentary rocks. In norther and central Peru, the miogeocline is located between a tectonic hinge adjacent to platformal facies of the Maranon geanticline on the east, and an outer marginal high bounded by the Cordillera Blanca fault and Tapacocha axis on the west. Miogeoclinal and platformal strata in southern Peru occur in a broad belt between Arequipa and Lago Titicaca. A marginal basin setting has been proposed for the Western Peruvian trough and the several kilometers of subsidence in the basin has been attributed to back-arc extension and crustal thinning. As a test of this model, quantitative tectonic subsidence curves were constructed from representative sections within miogeoclinar strata from four localities. Preliminary results indicate that the calculated curves have the same overall form as the age-depth curve for ocean floor, suggesting that subsidence was controlled by cooling and thermal contraction of heated lithosphere. The slopes of the curves are less than those for subsidence of oceanic lithosphere. However, they are in agreement with geologic evidence that the miogeocline accumulated on continental crust. Significant variations in the timing of onset, duration, and magnitude of subsidence are observed between sections from northern and southern Peru.

Full Text Available OBJECTIVES: To estimate Chlamydia trachomatis (CT infection prevalence and associated risk factors among a low-income marginalized urban population in Peru. METHODS: Between April 2003 and April 2005, men and women at high-risk for sexually transmitted infections (STIs were recruited from low-income urban areas in three coastal cities in Peru (Chiclayo, Lima, and Trujillo. Consenting participants were studied using a sero-epidemiologic survey. Urine and vaginal swabs collected from men and women were evaluated using polymerase chain reaction (PCR (COBAS® AMPLICOR (CT/NG Test, Roche Molecular Diagnostics, Branchburg, NJ, USA for CT. RESULTS: Among the 2 440 participants recruited for the study (2 145 men and 295 women, overall prevalence of CT infection was 6.6% (95% CI, 5.6-7.6%: 5.5% (95% CI, 4.5-6.5% in men and 14.9% (95% CI, 11.7-27.1% in women. Chlamydial infection was inversely associated with age and positively associated with HIV infection and dysuria in men. Among women, chlamydial infection was inversely associated with age and positively associated with number of sex partners. CONCLUSIONS: CT infection was common among high-risk men and women in urban coastal Peru. Because chlamydial infection is associated with complications related to female reproduction, including infertility and ectopic pregnancy, interventions to prevent and treat infection and studies to determine the feasibility of population-based screening for CT should be conducted among the high-risk female population.OBJETIVOS: Estimar la prevalencia de la infección por Chlamydia trachomatis y los factores de riesgo asociados en una población marginal urbana de bajos ingresos de Perú.

This article highlights population statistics from Peru, the 3rd largest country in Latin America. The population in 1985 has been estimated at 19.7 million. In 1982, the birth rate was 35/1000 and the mortality rate was 10/1000. Infant mortality stood at 99/1000 live births and life expectancy at birth was 59 years. 41% of Peru's population is under 15 years of age, and only 4% is 65 years of age or older. The country's total fertility rate is 5.2 births/woman. Only 0.4% of the population is foreign born. Peru is highly urbanized, and 65% of the country's total population growth in 1981 occurred in its cities. 1 in 3 Peruvians resides in the capital city of Lima. The 2 largest racial groups are mestizos and whites (53%) and Indians (46%). 21% of the population is illiterate. 40.7% of the labor force is employed in agriculture; however, only 15% of the national income is derived from agriculture. The GNP per capita was US$1040 in 1983. The country's economy is in serious trouble at present, with an annual inflation rate of 250% and a foreign debt of US$13.5 billion.

Lima's population grew from 1 million to 7 million during 1969-89, almost entirely due to rural-urban immigration. Other urban areas such as Iquitos experienced similar growth over the period. National, regional, and municipal governments have been working to restore civil order in the country and to bring basic health, sanitation, and education programs to the population. However, language, attitudinal, and cultural differences impede progress in this diverse and changing country. Peru's young population of median age 21 years presents a challenge to the development and implementation of effective reproductive health care programs for the country. Pathfinder's work in Peru is helped by current President Alberto Fujimori's strong and active support for family planning. In the face of strong opposition from the Roman Catholic Church, President Fujimori has held onto his conviction and commitment to reduce levels of maternal morbidity and mortality in Peru by increasing the accessibility of family planning programs. Pathfinder's work in Peru with the US Agency for International Development (USAID) includes the 5-year program Project 2000 designed to improve maternal and child health in 12 priority regions of the country. Pathfinder is also working with USAID to link family planning to postpartum services in 30 public hospitals throughout the country. New programs will be launched with contributions from individuals and foundations.

Oil, gas potential in shallow water: Peru`s continental shelf basins
Energy Technology Data Exchange (ETDEWEB)
Zuniga-Rivero, F.; Keeling, J.A.; Hay-Roe, H. [BPZ and Associates Inc., Houston, TX (United States)
1998-11-16
This third article of a series highlights the three sedimentary basins that underlie the 16 million acres of continental shelf adjacent to a 650-mile stretch of Peruvian coastline. This area lies roughly between the ports of Chiclayo and Pisco. These basins offer a variety of reservoirs, traps, and source-rock potential in water depths of less than 1,000 ft. They are characterized by a thick sequence of Neogene strata, underlain by Paleogene, Mesozoic, and Upper Paleozoic sediments down to as much as 7 sec two-way time on modern seismic records. In some places the sedimentary section may reach an aggregate thickness in excess of 50,000 ft. From north to south these contiguous shelf basins are the Sechura-Salaverry, Huacho, and Pisco basins. All three basins are described.

Venezuelan equine encephalitis (VEE) virus was isolated in 1993, 1994, and 1995 from human cases of acute, undifferentiated, febrile illness in the Peruvian Amazon Basin. Two virus isolates were recovered in 1994 from Peruvian soldiers at a jungle outpost near Pantoja in northern Peru, and 10 isolates were obtained from military personnel and civilians in 1993-1995 in Iquitos, an urban center in northeastern Peru. The genetic relationship of these isolates to other VEE virus strains was determined by sequencing 856-867 nucleotide reverse transcription-polymerase chain reaction fragments derived from the PE2 glycoprotein gene. The sequences were compared with those of other VEE virus strains, including representatives of the IAB, IC, ID, IE, II, and IIIC subtypes. The two Pantoja isolates were most closely related to subtype IC and ID viruses previously isolated in Colombia and Venezuela, and to the ID viruses isolated during the 1970s in Iquitos. All of the recent Iquitos isolates were similar to one another, but they were more closely related to Panamanian ID strains than to isolates previously obtained in Iquitos, Peru, or in Colombia and Venezuela. The recent Iquitos VEE viral isolates were the first Panama-genotype VEE ID virus strains identified outside of the Republic of Panama.

Peru turnaround tied to privatization
International Nuclear Information System (INIS)
Anon.
1993-01-01
Petroleos del Peru predicts a 10% increase in Peru's oil production this year and a further increase in 1994. Petroperu also forecasts a sharp increase in drilling in Peru this year. After several years of declining oil production, a gradual turnaround in the cash strapped country's petroleum industry is largely tied to its progress in privatization. The government last year began a campaign to privatize all state owned companies by the end of July 1995. The paper discusses forecasts by Petroperu; the contract of Occidental del Amazonas Inc.; the Petromar privatization; Great Western's contract; development of the Aguaytia gas field; and refinery contracts

Several archaeological studies in the Central Andes have pointed at the temporal coincidence of climatic fluctuations (both long- and short-term) and episodes of cultural transition and changes of socioeconomic structures throughout the pre-Columbian period. Although most scholars explain the connection between environmental and cultural changes by the impact of climatic alterations on the capacities of the ecosystems inhabited by pre-Columbian cultures, direct evidence for assumed demographic consequences is missing so far. In this study, we address directly the impact of climatic changes on the spatial population dynamics of the Central Andes. We use a large dataset of pre-Columbian mitochondrial DNA sequences from the northern Rio Grande de Nasca drainage (RGND) in southern Peru, dating from ∼840 BC to 1450 AD. Alternative demographic scenarios are tested using Bayesian serial coalescent simulations in an approximate Bayesian computational framework. Our results indicate migrations from the lower coastal valleys of southern Peru into the Andean highlands coincident with increasing climate variability at the end of the Nasca culture at ∼640 AD. We also find support for a back-migration from the highlands to the coast coincident with droughts in the southeastern Andean highlands and improvement of climatic conditions on the coast after the decline of the Wari and Tiwanaku empires (∼1200 AD), leading to a genetic homogenization in the RGND and probably southern Peru as a whole.

Bordetella pertussis is an important human pathogen that causes whooping cough (pertussis), an endemic illness responsible of significant morbidity and mortality, especially in infants and children. Worldwide, there are an estimated of 16 million cases of pertussis, resulting in about 195,000 child deaths per year. In Peru, pertussis is a major health problem that has been on the increase despite immunization efforts. The objective of this study was to determine the prevalence of B. pertussis among children under five years of age suspected to have whopping cough in Cajamarca, Peru. Children diagnosed with whooping cough admitted to the Hospital Regional de Cajamarca from August 2010 to July 2013 were included. Nasopharyngeal samples were obtained for B. pertussis culture and polymerase chain reaction (PCR) detection. In 133 children, the pertussis toxin and IS481 gene were detected in 38.35% (51/133) of the cases by PCR, while only 9.02% (12/133) of the Bordetella cultures were positive. The most frequent symptoms in patients with positive B. pertussis were paroxysm of coughing 68.63% (35/51), cyanosis 56.86% (29/51), respiratory distress 43.14% (22/51), and fever 39.22% (20/51). Pneumonia and acute bronchial obstructive syndrome were present in 17.65% (9/51) and 13.72% (7/51) of the cases, respectively. B. pertussis is responsible for an important proportion of whooping cough in hospitalized children in Cajamarca. Epidemiologic surveillance programs for B. pertussis are essential in Peru, especially in children who could most benefit from the vaccine.

Detrital zircon U-Pb age distributions from modern rivers and Mesozoic-Cenozoic basin fill in the northern Andes provide insights into pre-Andean, Andean, and active uplift and exhumation of distinctive sediment source regions. Diagnostic age signatures enable straightforward discrimination of competing sediment sources within the Andean magmatic arc (Western Cordillera-Central Cordillera), retroarc fold-thrust belt (Eastern Cordillera-Subandean Zone), and Amazonian craton (composed of several basement provinces). More complex, however, are the mid/late Cenozoic provenance records generated by recycling of basin fill originally deposited during early/mid Mesozoic extension, late Mesozoic thermal subsidence, and early Cenozoic shortening. Although subject to time-transgressive trends, regionally significant provenance patterns in Peru, Ecuador, and Colombia reveal: (1) Triassic-Jurassic growth of extensional subbasins fed by local block uplifts (with commonly unimodal 300-150 Ma age peaks); (2) Cretaceous deposition in an extensive postrift setting fed by principally cratonic sources (with common 1800-900 Ma ages); and (3) Cenozoic growth of a broad flexural basin fed initially fed by magmatic-arc rocks (100-0 Ma), then later dominance by thrust-belt sedimentary rocks with progressively greater degrees of basin recycling (yielding diverse and variable age populations from the aforementioned source regions). U-Pb results from modern rivers and smaller subbasins prove useful in evaluating source-to-sink relationships, downstream mixing relationships, hinterland-foreland basin connectivity, paleodrainage integration, and tectonic/paleotopographic reconstructions. Most but not all of the elevated intermontane basins in the modern hinterland of the northern Andes contain provenance records consistent with genesis in a broader foreland basin developed at low elevation. Downstream variations within modern axial rivers and Cenozoic axial basins inform predictive models of

In November 2013, a Plasmodium falciparum malaria outbreak of 11 cases occurred in Cusco, southern Peru, where falciparum malaria had not been reported since 1946. Although initial microscopic diagnosis reported only Plasmodium vivax infection in each of the specimens, subsequent examination by the national reference laboratory confirmed P. falciparum infection in all samples. Molecular typing of four available isolates revealed identity as the B-variant (BV1) strain that was responsible for a malaria outbreak in Tumbes, northern Peru, between 2010 and 2012. The P. falciparum BV1 strain is multidrug resistant, can escape detection by PfHRP2-based rapid diagnostic tests, and has contributed to two malaria outbreaks in Peru. This investigation highlights the importance of accurate species diagnosis given the potential for P. falciparum to be reintroduced to regions where it may have been absent. Similar molecular epidemiological investigations can track the probable source(s) of outbreak parasite strains for malaria surveillance and control purposes. PMID:26483121

Peru is an upper medium-income developing country with an increasing prevalence of chronic diseases, including diabetes. To review and describe the epidemiology, drivers, and diabetes care plan in Peru. The medical literature was reviewed based on systematic searching of PubMed, Scielo, and various gray literature from the International Diabetes Federation, World Health Organization, and local Peruvian agencies. In Peru, diabetes affects 7% of the population. Type 2 diabetes accounts for 96.8% of outpatients visits with this condition. Type 1 diabetes has an incidence of 0.4/100,000 per year, and gestational diabetes affects 16% of pregnancies. The prevalence of glucose intolerance is 8.11% and that of impaired fasting glucose 22.4%. The prevalence of overweight, obesity, and metabolic syndrome in adults is 34.7%, 17.5%, and 25%, respectively. Metabolic syndrome prevalence is greater in women and the elderly and at urban and low-altitude locations. Diabetes is the eighth cause of death, the sixth cause of blindness, and the leading cause of end-stage kidney disease and nontraumatic lower limb amputation. In Peru, diabetes accounts for 31.5% of acute myocardial infarctions and 25% of strokes. Infections, diabetic emergencies, and cardiovascular disorders are the main causes for admissions, with a mortality rate Diabetes is a major health care issue in Peru that exposes difficult challenges and shortcomings. The national strategy for tackling diabetes includes promotion of healthy lifestyles; training primary care physicians and providing them with evidence-based clinical practice guidelines, safe and effective medications, and tools for monitoring treatment; and, finally, construction of a comprehensive health care network for early referral in order to prevent, detect, and treat diabetic complications.

Severe Plasmodium falciparum malaria is uncommon in South America. Lima, Peru, while not endemic for malaria, is home to specialized centers for infectious diseases that admit and manage patients with severe malaria (SM), all of whom contracted infection during travel. This retrospective study describes severe travel-related malaria in individuals admitted to one tertiary care referral hospital in Lima, Peru; severity was classified based on criteria published by the World Health Organization in 2000. Data were abstracted from medical records of patients with SM admitted to Hospital Nacional Cayetano Heredia from 2006 to 2011. Of 33 SM cases with complete clinical data, the mean age was 39 years and the male/female ratio was 2.8. Most cases were contracted in known endemic regions within Peru: Amazonia (47%), the central jungle (18%), and the northern coast (12%); cases were also found in five (15%) travelers returning from Africa. Plasmodium vivax was most commonly identified (71%) among the severe infections, followed by P. falciparum (18%); mixed infections composed 11% of the group. Among the criteria of severity, jaundice was most common (58%), followed by severe thrombocytopenia (47%), hyperpyrexia (32%), and shock (15%). Plasmodium vivax mono-infection predominated as the etiology of SM in cases acquired in Peru. © The American Society of Tropical Medicine and Hygiene.

The relict forests of Northwest Peru and Southwest Ecuador
Directory of Open Access Journals (Sweden)
Maximilian Weigend
2013-05-01
Full Text Available The forest fragments or relict forests on the Western slopes of the Andes in northwest Peru and in south-west Ecuador are fragile ecosystems, which were largely continuous at some stage in the past. The importance and uniqueness of these forests as «refuges» and stable habitats roots partly in their complex diversity and their high levels of endemicity. These in turn are the outcome of a complex topography and ecology. In this introductory chapter 12 studies are analysed, which were presented at the Taller sobre Bosques Relictos de la Vertiente Occidental Andina del Norte del Perú y Sur del Ecuador in May 2004 at the X CONABOT, Trujillo-Perú. This helps to consolidate and update our knowledge on these over 20 forests fragments in northern Peru and two previously unknown fragments are presented for the first time: Bosque La Oscurana (Cajamarca and Kañaris (Lambayeque. Some ideas are exposed on the the relationships between the relict forests, how to analyse their dynamics, how to characterize their structure and how their conservation may be achieved. It is proposed that crucial elements in a conservation of these forests are a urgently inventorizing them to demonstrate their high diversity b emphasizing their economic potential with respect to the abundance of phytogenetic ressources c evaluating their role as catchment areas for the rivers which are the primary source of water for agriculture and urban life on the coast.

This work describes preliminary results from a 50 station broadband seismic network recently installed from the coast to the high Andes in Peru. UCLA's Center for Embedded Network Sensing (CENS) and Caltech's Tectonic Observatory are collaborating with the IRD (French L'Institut de Recherche pour le Developpement) and the Institute of Geophysics, in Lima Peru in a broadband seismic experiment that will study the transition from steep to shallow slab subduction. The currently installed line has stations located above the steep subduction zone at a spacing of about 6 km. In 2009 we plan to install a line of 50 stations north from this line along the crest of the Andes, crossing the transition from steep to shallow subduction. A further line from the end of that line back to the coast, completing a U shaped array, is in the planning phase. The network is wirelessly linked using multi-hop network software designed by computer scientists in CENS in which data is transmitted from station to station, and collected at Internet drops, from where it is transmitted over the Internet to CENS each night. The instrument installation in Peru is almost finished and we have been receiving data daily from 10 stations (out of total 50) since June 2008. The rest are recording on-site while the RF network is being completed. The software system provides dynamic link quality based routing, reliable data delivery, and a disruption tolerant shell interface for managing the system from UCLA without the need to travel to Peru. The near real-time data delivery also allows immediate detection of any problems at the sites. We are building a seismic data and GPS quality control toolset that would greatly minimize the station's downtime by alerting the users of any possible problems.

Although encephalomyocarditis virus (EMCV) infection has been commonly documented among domestic animals, less is known about EMCV transmission among humans. Recently, we described the isolation of EMCV from two febrile patients in Peru. To further investigate EMCV transmission in Peru, we screened febrile patients reporting to health clinics in Peru for serological evidence of recent EMCV infection. We also conducted a serological survey for EMCV-neutralizing antibodies in the city of Iquitos, located in the Amazon basin department of Loreto, Peru. Additionally, we screened serum from rodents collected from 10 departments in Peru for evidence of EMCV exposure. EMCV infection was found to be only rarely associated with acute febrile disease in Peru, accounting for 17% in cities in the tropical rainforest of northeastern Peru (Iquitos and Yurimaguas). On the basis of the serological survey conducted in Iquitos, risk factors for past infection include increased age, socioeconomic indicators such as residence construction materials and neighborhood, and swine ownership. Evidence from the rodent survey indicates that EMCV exposure is common among Murinae subfamily rodents in Peru (9.4% EMCV IgG positive), but less common among Sigmodontinae rodents (1.0% positive). Further studies are necessary to more precisely delineate the mode of EMCV transmission to humans, other potential disease manifestations, and the economic impact of EMCV transmission among swine in Peru.

1975-01-01
Single radial immune diffusion and counterelectrophoresis tests were used to examine 2,593 serum speciments from apparently healthy men, women, and children of Peru for the presence of hepatitis B antigen (Australia antigen). The object was to estimate the prevalence of the antigen in two contrasting geographic regions and to investigate the relationship between presence of the antigen and jungle hepatitis in eastern Peru. In connection with the latter goal, both single and serial serum samples collected from hepatitis cases during an epidemic in the northeast were also examined. Of the 2,593 apparently healthy subjects, the tests showed 1.4 per cent were carrying the antigen. However, when the data were broken down by geographic region it was found that 1.8 per cent of the subjects from eastern Peru were carriers, as compared to only 0.5 per cent of those from the northern coast. Moreover, incidences as high as 5 and 6.4 per cent were found in selected eastern areas, and a peak figure of 14.3 per cent was found in sera from children living in some of these areas. Comparison of the proportions of male and female sera positive for the antigen indicated that the proportion of males with HB Ag was nearly twice as high. However, sera collected from Indians of 20 different eastern tribes and from mestizos in the eastern region showed roughly the same proportion of samples positive for HB Ag in each ethnic group. The study also showed a close correlation between presence of the antigen and hepatitis infection during a 1972-1973 epidemic in eastern Peru. Testing of sera taken from hepatitis patients at that time showed many patients to be carrying HB Ag, specially in cases where serial blood samples were available. In all, positive test results were obtained for 81.2 per cent of the patients from whom two or more samples had been obtained.

The Andes Mountains exert critical controls on the climate, hydrology, and biodiversity of South America. The Bagua Basin, a low elevation (400-600 m) intermontane basin in northern Peru, offers a unique opportunity to study the ecological, climatic, and structural evolution of the western topographic boundary of the Amazonian foreland. Situated between the Marañon fold-thrust belt of the Western Cordillera and basement block uplifts of the Eastern Cordillera, the Bagua region contains a protracted, semi-continuous record of Triassic through Pleistocene sedimentation. Whereas Triassic-Cretaceous marine deposits were potentially related to extension and regional thermal subsidence, a Paleocene-Eocene shift to shallow marine and fluvial systems marks the onset of foreland basin conditions. Oligocene-Miocene sedimentation corresponds to a braided-meandering fluvial system with exceptional development of paleosols. In this study, we use new detrital zircon U-Pb geochronologic and oxygen stable isotopic datasets to establish a chronology of pre-Andean and Andean processes within the Bagua Basin. Detrital zircon geochronology provides constraints on when the Western and Eastern cordilleras shed sediments into the basin. Syndepositional zircons within Eocene, Oligocene and Miocene strata provide key age control for a previously poorly constrained depositional chronology. Preliminary results suggest a dramatic provenance shift in which Paleocene deposits contain almost exclusively cratonic populations (500-1600 Ma) whereas Eocene deposits show a mix of syndepositional zircons from the magmatic arc, recycled Mesozoic zircons, and cratonic zircon populations. Oxygen stable isotopes (δ18O) of carbonate nodules from Neogene paleosols will help elucidate when the Eastern Cordillera became an orographic barrier intercepting moisture from the Amazon basin to the east. Together, these records will help uncover the history of tectonics and climate interaction in tropical South

After months of delays, the sale of Petroleos del Peru SA (Petroperu) was postponed earlier this year until after the elections, which saw Peru`s incumbent President Alberto Fujimori reelected. In June, Fujimori appointed Amado Yataco Minister of Energy and Mines. Yataco, also serving as president of the privatization commission Copri, said a decision on the sale of Petroperu would be made quickly, perhaps by July 28, ahead of this report`s presstime. The uncertain status of Petroperu has not, however, slowed activity in Peru`s petroleum sector.

Malaria in Peru, dominated by Plasmodium vivax, remains a public health problem. The 1990s saw newly epidemic malaria emerge, primarily in the Loreto Department in the Amazon region, including areas near to Iquitos, the capital city, but sporadic malaria transmission also occurred in the 1990s-2000s in both north-coastal Peru and the gold mining regions of southeastern Peru. Although a Global Fund-supported intervention (PAMAFRO, 2005-2010) was temporally associated with a decrease of malaria transmission, from 2012 to the present, both P. vivax and Plasmodium falciparum malaria cases have rapidly increased. The Peruvian Ministry of Health continues to provide artemesinin-based combination therapy for microscopy-confirmed cases of P. falciparum and chloroquine-primaquine for P. vivax Malaria transmission continues in remote areas nonetheless, where the mobility of humans and parasites facilitates continued reintroduction outside of ongoing surveillance activities, which is critical to address for future malaria control and elimination efforts. Ongoing P. vivax research gaps in Peru include the following: identification of asymptomatic parasitemics, quantification of the contribution of patent and subpatent parasitemics to mosquito transmission, diagnosis of nonparasitemic hypnozoite carriers, and implementation of surveillance for potential emergence of chloroquine- and 8-aminoquinoline-resistant P. vivax Clinical trials of tafenoquine in Peru have been promising, and glucose-6-phosphate dehydrogenase deficiency in the region has not been observed to be a limitation to its use. Larger-scale challenges for P. vivax (and malaria in general) in Peru include logistical difficulties in accessing remote riverine populations, consequences of government policy and poverty trends, and obtaining international funding for malaria control and elimination. © The American Society of Tropical Medicine and Hygiene.

Occupational Safety and Health in Peru.
Cruz, Ismael; Huerta-Mercado, Raul
2015-01-01
Peru is a country located on the Pacific coast of South America with a population of more than 30 million inhabitants. In the past 10 years, Peru has had a steady economic growth. Peru is predominantly an extractive industry country, but the manufacturing and construction sectors are booming. It is in this context that regulations have been implemented to protect the safety and health of workers. One of the most important regulations is the Law on Safety and Health at Work, which has been recently promulgated. Regulations are complemented by training and education in occupational safety and health. The measures are yet to be fully implemented thus a positive effect in reducing accidents and occupational diseases at work has not yet been seen. Copyright © 2015 The Authors.

We describe a new species of Stenocercus from the montane forest of the right margin of the Marañón river in the northern portion of the Central Andes in northern Peru (Amazonas and La Libertad departments), at elevations ranging from 2300 to 3035 m. Stenocercus omari sp. nov. differs from other Stenocercus species, with the exception of S. amydrorhytus, S. chrysopygus, S. cupreus, S. johaberfellneri, S. latebrosus, S. melanopygus, S. modestus, S. ornatissimus, S. orientalis, and S. stigmosus, by having granular scales on the posterior surfaces of thighs, a conspicuous antehumeral fold and by lacking a vertebral crest. However, Stenocercus omari sp. nov. is easily distinguished from the aforementioned species, except S. orientalis, by the presence of prominently keeled dorsal head scales. The new species differs from S. orientalis by lacking a prominent oblique neck fold and by having a distinct deep postfemoral mite pocket.

Supergene nonsulfide ores form from the weathering of sulfide mineralization. Given the geochemical affinity of Ge to Si4+ and Fe3+, weathering of Ge-bearing sulfides could potentially lead to Ge enrichments in silicate and Fe-oxy-hydroxide minerals, although bulk rock Ge concentrations in supergene nonsulfide deposits are rarely reported. Here, we present the results of an investigation into Ge concentrations and deportment in the Cristal supergene Zn nonsulfide prospect (Bongará, northern Peru), which formed from the weathering of a preexisting Mississippi Valley-type (MVT) sulfide deposit. Material examined in this study originates from drillcore recovered from oxidized Zn-rich bodies 15-20 m thick, containing 5-45 wt% Zn and Ge concentrations 100 ppm. Microanalysis and laser ablation-ICP-MS show that precursor sphalerite is rich in both Fe (mean Fe = 8.19 wt%) and Ge (mean Ge = 142 ppm). Using the mineral geothermometer GGIMFis—geothermometer for Ga, Ge, In, Mn, and Fe in sphalerite—proposed by Frenzel et al. (Ore Geol Rev 76:52-78, 2016), sphalerite trace element data from the Cristal prospect suggest a possible formation temperature ( T GGIMFis) of 225 ± 50 °C, anomalously high for a MVT deposit. Germanium concentrations measured in both goethite (mean values 100 to 229 ppm, max 511 ppm) and hemimorphite (mean values 39 to 137 ppm, max 258 ppm) are similar to concentrations measured in hypogene sphalerite. Additionally, the Ge concentrations recorded in bulk rock analyses of sphalerite-bearing and oxidized samples are also similar. A persistent warm-humid climate is interpreted for the region, resulting in the development of an oxidation zone favoring the formation of abundant Zn hydrosilicates and Fe hydroxides, both able to incorporate Ge in their crystal structure. In this scenario, Ge has been prevented from dispersion during the weathering of the Ge-bearing sulfide bodies and remains in the resultant nonsulfide ore.

Full Text Available Zn-bearing phyllosilicates are common minerals in nonsulfide Zn deposits, but they seldom represent the prevailing economic species. However, even though the presence of Zn-bearing clays is considered as a disadvantage in mineral processing, their characteristics can give crucial information on the genesis of the oxidized mineralization. This research has been carried out on the Mina Grande and Cristal Zn-sulfide/nonsulfide deposits, which occur in the Bongará district (Northern Peru. In both of the deposits, Zn-bearing micas and clays occur as an accessory to the ore minerals. The XRD analyses and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS investigations revealed that the Zn-bearing micas that are occurring in both deposits mostly consist of I/S mixed layers of detrital origin, which have been partly altered or overprinted by sauconite during the supergene alteration of sulfides. Sporadic hendricksite was also identified in the Cristal nonsulfide mineral assemblage, whereas at Mina Grande, the fraipontite-zaccagnaite (3R-polytype association was detected. The identified zaccagnaite polytype suggests that both fraipontite and zaccagnaite are genetically related to weathering processes. The hendricksite detected at Cristal is a product of hydrothermal alteration, which is formed during the emplacement of sulfides. The complex nature of the identified phyllosilicates may be considered as evidence of the multiple processes (hydrothermal and supergene that occurred in the Bongará district.

Rivers as Political Boundaries: Peru and its Dynamic Borders
Abad, J. D.; Escobar, C.; Garcia, A. M. P.; Ortals, C.; Frias, C. E.; Vizcarra, J.
2014-12-01
Rivers, although inherently dynamic, have been chosen as political boundaries since the beginning of colonization for several reasons. Such divisions were chosen namely for their defensive capabilities and military benefits, and because they were often the first features mapped out by explorers. Furthermore, rivers were indisputable boundaries that did not require boundary pillars or people to guard them. However, it is important to understand the complexities of a river as a boundary. All rivers inevitably change over time through processes such as accretion, deposition, cut-off, or avulsion, rendering a political boundary subject to dispute. Depending upon the flow, size, and surrounding land, a river will migrate differently than others. As these natural features migrate one country loses land while another gains land leading to tension between legal rigidity and fluid dynamism. This in turn can manifest in social disruption due to cultural differences, political upheaval, or conflict risk as a result of scarce water resources. The purpose of this research is to assess the temporal and spatial variability of the political boundaries of Peru that follow rivers. Peru shares borders with Colombia, Brazil, Bolivia, Chile, and Ecuador. A large part of its northern border with Colombia follows the Putumayo River and later the Amazon River. Part of its eastern border with Brazil follows the Yavari River and later the Yaquirana River. These rivers are natural features used as political boundaries yet they differ in how each migrates. By means of a spatial and temporal analysis of satellite images it was possible to obtain erosion and deposition areas for the Putumayo River, the portion of the Amazon River that is part of the Peruvian boundary, the Yavari River, and the Yaquirana River. The erosion and deposition areas were related to land distribution among Peru, Colombia, and Brazil. By examining the Digital Elevation Model one can see how the altitude of the

[Fertility transition in Peru].
Ferrando, D; Aramburu, C E
1992-12-01
Data from national censuses and sample surveys are the basis for this examintion of differential fertility and the fertility transition in Peru. Changes in the level and structure of fertility in the 3 major geographic regions are compared, and the role of contraceptive usage and nuptiality changes in the fertility decline are analyzed. Peru's total fertility rate was estimated at 6.85 in 1965 and has since declined to 6.56 in 1965-70, 6.00 in 1970-75, 5.30 in 1975-80, 4.65 in 1980-85, and 4.00 in 1985-90. The fertility decline varied in intensity and timing in the geographic regions. A clear fertility decline began among upper and middle income groups in the principal cities in the 1960s, spreading gradually to the urban low income sectors. Not until the late 1970s did the fertility decline spread to the rest of the population, coinciding with the years of severe economic crisis. The urban total fertility rate declined from 6 to 3.77 during 1961-86, but rural fertility increased through 1972 to 8.12, before declining slightly to 7.62 in 1981 and more markedly to 6.65 in 1986. Sociocultural and economic differences between Peru's natural regions are appreciable, and account for the contrasts in fertility trends. The greatest changes occurred in metropolitan Lima, which already had relatively low fertility in 1961. Its total fertility rate declined 44% from 5.6 in 1961 to 3.13 in 1986. Fertility declined by slightly under 40% in the rest of the coast, by almost 25% in the jungle, and by scarcely 14% in the sierra. The total fertility rates in 1961 and 1986, respectively, were 6.38 and 4.13 on the coast, 6.64 and 6.45 in the highlands, and 7.92 and 5.97 in the lowlands. The fertility decline, especially in the lower classes, was a response initially to the process of cultural modernization which in slightly over 2 decades saw a profound transformation of Peru from a rural, Andean, illiterate, and agrarian society to an urban, coastal, literate, and commercial society

2015-07-01
Neurogenetics, the science that studies the genetic basis of the development and function of the nervous system, is a discipline of recent development in Peru, an emerging Latin American country. Herein, we review the clinical, scientific and ethical aspects regarding the development of this discipline, starting with the first molecular diagnosis of neurogenetic diseases, to family and population-based genetic association studies. Neurogenetics in Peru aims to better explain the epidemiology of monogenic and complex neurodegenerative disorders that will help in implementing public health policies for these disorders. The characterization of Peru and its health system, legal issues regarding rare diseases and the historical milestones in neurogenetics are also discussed.

Energy Technology Data Exchange (ETDEWEB)
1979-08-01
A comprehensive assessment of the biofuel potential of Peru is presented. Topics discussed cover current biofuel utilization practices; evaluation of Peruvian biomass productivity; identification of Peruvian agricultural and forestry resources; assessment of resource development and management concerns; identification of market considerations; description of biofuel technological options; and regional identification of biofuel technology applications. The discussion of current biofuel utilization centers on a qualitative description of the main conversion approaches now being practiced in Peru. Biomass productivity is evaluated in the context of the terrain, soil, and climatic conditions found in Peru. A quantitative description of the energy potential that could be realized from agricultural and forestry resources of Peru follows. A regional picture is given for the production of agricultural residues and forest resources that could potentially supply energy. The assessment of resource development and management concerns focuses on harvesting, reforestation, training, and the environmental consequences of utilization of forest resources. Market factors assessed include: importation, internal market development, external market development, energy policy and pricing, and transportation. Ten biofuel technology options for Peru were identified: small- to medium-scale gasification, a wood waste inventory, stationary and mobile charcoal production systems, wood distillation, forest resource development and management, electrical cogeneration, anaerobic digestion technology, development of ethanol production capabilities, and agricultural strategies for fuel production.Based upon these biofuel options, nine applications were identified for the Costa Region, eight for the Sierra Region, and ten for the Selva Region.

1600 AD Huaynaputina Eruption (Peru, Abrupt Cooling, and Epidemics in China and Korea
Directory of Open Access Journals (Sweden)
Jie Fei
2016-01-01
Full Text Available The 1600 AD Huaynaputina eruption in Peru was one of the largest volcanic eruptions in history over the past 2000 years. This study operated on the hypothesis that this event dramatically affected the weather and environment in China and the Korean Peninsula. Over the course of this research the Chinese and Korean historical literatures as well as dendrochronology records were examined. The historical evidence points to the conclusion that the eruption was followed by an abrupt cooling period and epidemic outbreaks in 1601 AD within both China and the Korean Peninsula. These records manifested themselves in unseasonably cold weather resulting in severe killing frosts in northern China in the summer and autumn of 1601 AD. In southern China (Zhejiang and Anhui Provinces and Shanghai Municipality, July was abnormally cold with snow, with an autumn that saw anomalously hot weather. In addition, there was unseasonable snowfall that autumn within Yunnan Province. Widespread disease outbreaks occurred in August, September, and October in northern and southern China. In Korea, the spring and early summer of 1601 AD were unusually cold, and conditions led to further widespread epidemics occurring in August.

A report has recently been published which describes the findings of the International Uranium Resources Evaluation Project (TUREP) Mission to Peru. The IUREP Orientation Phase Mission to Peru estimates that the Speculative Resources of that country fall within the range of 6 000 to 11 000 tonnes uranium. The majority of this potential is expected to be located in Late Tertiary ignimbrites and associated sediments in the high Andes of southern Peru. Other favourable geological environments include calcretes, developed from Tertiary volcanogenic sources over the Precambrian in the Pacific Coastal desert in southern Peru, and Hercynian subvolcanic granites in the eastern Cordillera of southern Peru. The Mission recommends that over a period of five years approximately U.S. $10 million be spent on exploration in Peru. The majority of this would be spent on drilling ($5 million) and tunnelling ($2 million) with an additional $3 million on surface and airborne radiometric surveys. (author)

Crop improvement projects in Peru
International Nuclear Information System (INIS)
Broeshart, H.
1978-01-01
Only two percent of the territory of Peru consists of arable land. Sixteen million people depend on the production of about three million hectares of land, which means that on the average only 1800 square metres is available per person. It is clear that Peru is one of the poorest countries of the world as far as available arable land is concerned and consequently it will have to drastically increase its agricultural production per unit area or import large quantities of agricultural products to feed its rapidly growing population. Agricultural research on the efficient use of fertilizers is being carried out by the regional experiment station (CRIA), by the National University of Agriculture, La Molina, Lima, dealing with programmes on maize, potatoes, cereals and forage crops, by national universities in the country and by specialized research institutes for tropical agriculture on sugar-cane, cotton, coffee and tea. Isotope and radiation techniques are a particularly effective means of determining the best cultural practices for the efficient use of fertilizers and water, and the Joint FAO/IAEA Division of Atomic Energy in Food and Agriculture has been involved in the organization of field and greenhouse programmes at experiment stations and universities in Peru since 1963

Economic impact of cystic echinococcosis in peru.
Moro, Pedro L; Budke, Christine M; Schantz, Peter M; Vasquez, Julio; Santivañez, Saul J; Villavicencio, Jaime
2011-05-01
Cystic echinococcosis (CE) constitutes an important public health problem in Peru. However, no studies have attempted to estimate the monetary and non-monetary impact of CE in Peruvian society. We used official and published sources of epidemiological and economic information to estimate direct and indirect costs associated with livestock production losses and human disease in addition to surgical CE-associated disability adjusted life years (DALYs) lost. The total estimated cost of human CE in Peru was U.S.$2,420,348 (95% CI:1,118,384-4,812,722) per year. Total estimated livestock-associated costs due to CE ranged from U.S.$196,681 (95% CI:141,641-251,629) if only direct losses (i.e., cattle and sheep liver destruction) were taken into consideration to U.S.$3,846,754 (95% CI:2,676,181-4,911,383) if additional production losses (liver condemnation, decreased carcass weight, wool losses, decreased milk production) were accounted for. An estimated 1,139 (95% CI: 861-1,489) DALYs were also lost due to surgical cases of CE. This preliminary and conservative assessment of the socio-economic impact of CE on Peru, which is based largely on official sources of information, very likely underestimates the true extent of the problem. Nevertheless, these estimates illustrate the negative economic impact of CE in Peru.

Peru steps up push to attract oil investment
International Nuclear Information System (INIS)
Anon.
1991-01-01
This paper reports that Peru's government is stepping up efforts to attract more foreign investment in its oil and gas sector. Since taking over in July 1990, the government of President Alberto Fujimori has taken a number of steps to privatize the oil sector, improve the fiscal regime for oil investment, and streamline regulations on oil and gas investment. In the most dramatic step, the Fujimori administration ended state oil company Petroleos del Peru's monopoly on downstream operations as well as imports and exports of oil and gas as part of sweeping new oil and gas legislation. In addition, officials of the Fujimori administration have been traveling to key oil centers around the world with a presentation on Peru's hydrocarbon potential, trying to spark interest in E and D investment there

2015-05-01
During 2010-2012, an outbreak of 210 cases of malaria occurred in Tumbes, in the northern coast of Peru, where no Plasmodium falciparum malaria case had been reported since 2006. To identify the source of the parasite causing this outbreak, we conducted a molecular epidemiology investigation. Microsatellite typing showed an identical genotype in all 54 available isolates. This genotype was also identical to that of parasites isolated in 2010 in the Loreto region of the Peruvian Amazon and closely related to clonet B, a parasite lineage previously reported in the Amazon during 1998-2000. These findings are consistent with travel history of index case-patients. DNA sequencing revealed mutations in the Pfdhfr, Pfdhps, Pfcrt, and Pfmdr1 loci, which are strongly associated with resistance to chloroquine and sulfadoxine/pyrimethamine, and deletion of the Pfhrp2 gene. These results highlight the need for timely molecular epidemiology investigations to trace the parasite source during malaria reintroduction events.

Safe management of discussed sealed sources in Peru
International Nuclear Information System (INIS)
Mallaupoma, M.
2000-01-01
The future safe development of nuclear energy and progressive increasing use of sealed sources in medicine, research, industry and other fields in Peru, in the past years have determined the necessity to formulate and apply an Institutional policy to assure harmless and ecologically rational management of disused sealed sources in Peru. Some results of the studies, which served as a basis for design and construction of a facility for treatment, conditioning and storage of conditioned sealed sources are presented in this paper. The waste management system in Peru comprises operational and regulatory capabilities. Both of these activities are performed under a legislation. The Nuclear Research Center RACSO has a radioactive waste management department which is in charge of the management of disused sealed sources produced in the country. It is considered as a centralized waste processing and storage facility (WPSF). (author)

The application of a topical medication containing balsam of Peru to the skin of an infant, particularly in the occluded diaper area, seems a great way to sensitize the infant not only to balsam of Peru but also to our fragrant environment.

The public sectors of developing countries require strengthened capacity in health informatics. In Peru, where formal university graduate degrees in biomedical and health informatics were lacking until recently, the AMAUTA Global Informatics Research and Training Program has provided research and training for health professionals in the region since 1999. The Fogarty International Center supports the program as a collaborative partnership between Universidad Peruana Cayetano Heredia in Peru and the University of Washington in the United States of America. The program aims to train core professionals in health informatics and to strengthen the health information resource capabilities and accessibility in Peru. The program has achieved considerable success in the development and institutionalization of informatics research and training programs in Peru. Projects supported by this program are leading to the development of sustainable training opportunities for informatics and eight of ten Peruvian fellows trained at the University of Washington are now developing informatics programs and an information infrastructure in Peru. In 2007, Universidad Peruana Cayetano Heredia started offering the first graduate diploma program in biomedical informatics in Peru.

[Neurogenetics in Peru, example of translational research].
Mazzetti, Pilar; Inca-Martínez, Miguel; Tirado-Hurtado, Indira; Milla-Neyra, Karina; Silva-Paredes, Gustavo; Vishnevetsky, Anastasia; Cornejo-Olivas, Mario
2015-10-01
Neurogenetics is an emerging discipline in Peru that links basic research with clinical practice. The Neurogenetics Research Center located in Lima, Peru is the only unit dedicated to the specialized care of neurogenetic diseases in the country. From the beginning, neurogenetics research has been closely linked to the study of Huntingtons Disease (HD), from the PCR genotyping of the HTT gene, to the current haplogroup studies in HD. Research in other monogenic diseases led to the implementation of alternative methodologies for the genotyping of Fragile X and Myotonic Dystrophy Type 1. Both, national and international collaborative efforts have facilitated the discovery of new genetic variants in complex multigenic diseases such as Parkinsons disease and Alzheimers disease. Additionally, multidisciplinary education and mentoring have allowed for the training of new neurogenetics specialists, supporting the sustained growth of the discipline in the country. The promotion of research in Peru has spurred the growth of neurogenetics research, although limitations in infrastructure, technology, and education remain a challenge for the further growth of research in this field.

Peru 2007 tsunami runup observations and modeling
Fritz, H. M.; Kalligeris, N.; Borrero, J. C.
2008-05-01
On 15 August 2007 an earthquake with moment magnitude (Mw) of 8.0 centered off the coast of central Peru, generated a tsunami with locally focused runup heights of up to 10 m. A reconnaissance team was deployed in the immediate aftermath and investigated the tsunami effects at 51 sites. The largest runup heights were measured in a sparsely populated desert area south of the Paracas Peninsula resulting in only 3 tsunami fatalities. Numerical modeling of the earthquake source and tsunami suggest that a region of high slip near the coastline was primarily responsible for the extreme runup heights. The town of Pisco was spared by the presence of the Paracas Peninsula, which blocked tsunami waves from propagating northward from the high slip region. The coast of Peru has experienced numerous deadly and destructive tsunamis throughout history, which highlights the importance of ongoing tsunami awareness and education efforts in the region. The Peru tsunami is compared against recent mega-disasters such as the 2004 Indian Ocean tsunami and Hurricane Katrina.

A detailed understanding of the range of the golden-mantle tamarin, Saguinus tripartitus (Milne Edwards, 1878), in Amazonian Peru and Ecuador is of particular relevance, not only because it is poorly known but also because it was on the basis of its supposed sympatry with the saddleback tamarin (S. fuscicollis lagonotus) that Thorington (Am J Primatol 15:367-371, 1988) argued that it is a distinct species rather than a saddleback tamarin subspecies, as was believed by Hershkovitz (Living new world monkeys, vol I. The University of Chicago Press, Chicago, 1977). A number of surveys have been carried out since 1988 in the supposed range of S. tripartitus, in both Ecuador and Peru. Here we summarize and discuss these issues and provide a new suggestion for the geographic range of this species; that is, between the ríos Napo and Curaray in Peru and extending east into Ecuador. We also review current evidence for the distributions of Spix's black-mantle tamarin (S. nigricollis nigricollis), Graells' black-mantle tamarin (S. n. graellsi), and the saddleback tamarin (S. fuscicollis lagonotus), which are also poorly known, and examine the evidence regarding sympatry between them. We conclude that despite the existence of a number of specimens with collecting localities that indicate overlap in their geographic ranges, the fact that the four tamarins are [corrected] of similar size and undoubtedly very similar in their feeding habits militates strongly against the occurrence of sympatry among them.

An astronomical observatory for Peru
del Mar, Juan Quintanilla; Sicardy, Bruno; Giraldo, Víctor Ayma; Callo, Víctor Raúl Aguilar
2011-06-01
Peru and France are to conclude an agreement to provide Peru with an astronomical observatory equipped with a 60-cm diameter telescope. The principal aims of this project are to establish and develop research and teaching in astronomy. Since 2004, a team of researchers from Paris Observatory has been working with the University of Cusco (UNSAAC) on the educational, technical and financial aspects of implementing this venture. During an international astronomy conference in Cusco in July 2009, the foundation stone of the future Peruvian Observatory was laid at the top of Pachatusan Mountain. UNSAAC, represented by its Rector, together with the town of Oropesa and the Cusco regional authority, undertook to make the sum of 300,000€ available to the project. An agreement between Paris Observatory and UNSAAC now enables Peruvian students to study astronomy through online teaching.

Geomorphic Effects, Chronologies, and Archaeological Significance of El Nino Floods in Southern Peru
Magilligan, F. J.; Manners, R.; Goldstein, P.
2003-12-01
The catastrophic effects of large floods have been well documented, on both contemporary and paleo-timecales, especially for the conterminous U.S. Less is known, however, about extreme events in hyper-arid sub-tropical climates where synoptic scale meteorological causes, such as El Nino-Southern Oscillation events, are the driving atmospheric mechanism. This research documents the geomorphic effects of extreme floods in the Moquegua River valley of southern Peru, in the core of the Atacama Desert. Using a combination of geomorphic mapping, hydrolologic modeling, aerial photography, ASTER satellite imagery, and GIS, we document the geomorphic signature of large contemporary floods within the mid-valley section (1500 masl) of the Rio Moquegua. Stratigraphic evidence and paleostage indicators of paleofloods, such as slackwater deposits and preserved high level flood gravels, are used to evidence late Holocene paleoflood magnitude-frequency relationships. On contemporary timescales, channel belt expansion by lateral erosion during large floods, such as the recent '97 and '98 floods, correspond to as much as 30-40 hectares of floodplain loss along the 20 km study reach. Sixty years of repeat aerial photography indicates that channel belt expansion and floodplain erosion commonly occurs along the Rio Moquegua. The frequent resetting of floodplain alluvium conditioned by these large floods is supported by radiocarbon dating of floodplain exposures. These dates indicate that most of the contemporary floodplain alluvium is younger that 560 14C yrs BP. The highest terrace remnants date to 3250 14C yrs BP and record a series of overbank flood gravels. Evidence for the regionally extensive Miraflores ENSO flood, ca. 1300 AD, exists in tributary and along mainstem sections. This flood has been documented along the coasts of Northern Chile to northern Peru, and has been evoked to explain significant social collapse. Our field evidence indicates that it catastrophically affected

Molecular Epidemiology of Plasmodium falciparum Malaria Outbreak, Tumbes, Peru, 2010–2012

During 2010–2012, an outbreak of 210 cases of malaria occurred in Tumbes, in the northern coast of Peru, where no Plasmodium falciparum malaria case had been reported since 2006. To identify the source of the parasite causing this outbreak, we conducted a molecular epidemiology investigation. Microsatellite typing showed an identical genotype in all 54 available isolates. This genotype was also identical to that of parasites isolated in 2010 in the Loreto region of the Peruvian Amazon and closely related to clonet B, a parasite lineage previously reported in the Amazon during 1998–2000. These findings are consistent with travel history of index case-patients. DNA sequencing revealed mutations in the Pfdhfr, Pfdhps, Pfcrt, and Pfmdr1 loci, which are strongly associated with resistance to chloroquine and sulfadoxine/pyrimethamine, and deletion of the Pfhrp2 gene. These results highlight the need for timely molecular epidemiology investigations to trace the parasite source during malaria reintroduction events. PMID:25897626

Cultivation of minor tuber crops in Peru and Bolivia
Directory of Open Access Journals (Sweden)

Full Text Available A collection mission of three Andean tuber crops, oca (Oxalis tuberosa, Oxalidaceae, ulluco (Ullucus tuberosus, Basellaceae and añu (Tropaeolum tuberosum, Tropaeolaceae, was carried out in southern Peru, Bolivia and northern Argentina. This article deals with the observations made during this mission. 55 ulluco fields were visited. In general, the fields are small, 240m2 on average, and they are mostly situated on mountain slopes. The fields are fertilized with animal dung; chemical fertilizers are quite rare. In the fields, people work with hoes ang ploughs as they did hundreds of years ago. Mechanization of agriculture would prevent full utilization of the mountainous area of the Andes. Ulluco is usually interplanted with other crops, usually, many forms of ulluco in one field. Because of crop rotation description of the fields is partly valid for the cultivation of other crops, too. Due to drastic climatic variation, cultivation of mixed varieties maybe the best way to guarantee some yield. When results of the investigations are wished to benefit developing countries, knowledge of social, agricultural and environmental factors is of great value.

Fossil Cenozoic crassatelline bivalves from Peru: New species and generic insights
Directory of Open Access Journals (Sweden)
Thomas J. DeVries
2016-08-01
Full Text Available Discoveries of new fossil Cenozoic crassatellines in Peru provide a new phylogenetic perspective on “large” Neogene genera, in which four lineages are considered to have arisen independently from different Paleogene Crassatella ancestors. Latest Oligocene and early Miocene species of the new genus Tilicrassatella gen. nov.―T. ponderosa, T. torrens sp. nov., and T. sanmartini sp. nov. from the East Pisco Basin―probably evolved from the late Eocene species, Crassatella rafaeli sp. nov., which itself differed in significant respects from slightly older species of the East Pisco Basin, C. neorhynchus and C. pedroi sp. nov. The paciphilic genus, Hybolophus, is raised to full generic status. Added to its ranks are the East Pisco Miocene species H. maleficae sp. nov., H. terrestris sp. nov., and the oldest species of the genus, the late Eocene or Oligocene H. disenum sp. nov. from the Talara Basin of northern Peru. Kalolophus gen. nov., encompassing circum-Caribbean fossil species, the extant species, K. speciosus, and the trans-isthmus species, K. antillarum, appears to have evolved from the early Oligocene Floridian species, Crassatella portelli sp. nov. The genus Marvacrassatella is a western Atlantic Miocene lineage most likely descended from Kalolophus. The genus Eucrassatella is restricted to Australian and New Zealand taxa. The Eocene New Zealand species, Spissatella media, is transferred to Eucrassatella and deemed a candidate for the most recent common ancestor of younger Eucrassatella and all Spissatella species. In the southern Pacific Ocean, the circum-Caribbean region, and tropical western America, crassatelline lineages developed one or more of the following characters: large resilifers, smooth ventral margins, and an extended left anterior cardinal tooth. Some of these late Paleogene convergent character changes might have countered increased shear forces exerted on the crassatelline valves while burrowing into finer-grained and

Current approaches to gastric cancer in Peru and Mexico.
Santos, Erlan
2017-01-01
In Peru, the incidence of gastric cancer is reported to be around 15.8 per 100,000 inhabitants and it is the second most common oncological disease in men and the third one in women. Additionally, a high mortality index was reported, especially among poor people. To address this issue, in 2008, Peru initiated several insurance treatment plans of oncological diseases with promising results. In Mexico, there is a high predominance of gastric cancer in male gender compared to female gender, even reaching a 2/1 ratio, and the detection rate of early gastric cancer is low (10% to 20%) which results in a mainly palliative treatment with an overall survival rate in 5 years about 10% to 15% only. In Peru, the average age at diagnosis is around 62.96±14.75 years old and the most frequent symptoms includes abdominal pain, indigestion, loss of appetite, weight loss and gastrointestinal bleeding, while in Mexico, some studies reported an average age at diagnosis around 60.3±4.1 years old (range, 23-78 years old) and the most frequent symptoms were postprandial fullness (74.4%), abdominal pain (37.2%), weight loss (18.6%), and melena (4.6%). The anemia rate was 65.1% with a mean Hb level of 6.14 g/dL. In Peru, the most common gastric cancer type is the intestinal-type adenocarcinoma (around 34%), followed by the diffuse-type adenocarcinoma (18.7%), whilst among Mexicans, the diffuse-type was reported in 55.2% of cases, the intestinal-type was reported in 28.2% and the undifferentiated-type corresponded to 6%. In both, Peru and Mexico, 90% of the associated factors includes tabaquismo, diets rich in salt, smoked foods, and a sedentary lifestyle. Family inheritance and advanced age and pharmacological-resistant Helicobacter pylori infection are also important. Poverty has been heavily associated with a higher incidence of gastric cancer. The management of gastric cancer patients in Peru is carried out by general surgeons or general surgical oncologists. In recent years, efforts

Eugenics, medicine and psychiatry in Peru.
Stucchi-Portocarrero, Santiago
2018-03-01
Eugenics was defined by Galton as 'the science which deals with all influences that improve the inborn qualities of a race'. In Peru, eugenics was related to social medicine and mental hygiene, in accordance with the neo-Lamarckian orientation, that predominated in Latin America. Peruvian eugenists assumed the mission of fighting hereditary and infectious diseases, malnutrition, alcoholism, drug addiction, prostitution, criminality and everything that threatened the future of the 'Peruvian race'. There were some enthusiastic advocates of 'hard' eugenic measures, such as forced sterilization and eugenic abortion, but these were never officially implemented in Peru (except for the compulsory sterilization campaign during the 1995-2000 period). Eugenics dominated scientific discourse during the first half of the twentieth century, but eugenic discourse did not disappear completely until the 1970s.

Neurocysticercosis is a leading cause of seizures and epilepsy in most of the world, and it occurs when Taenia solium larval cysts infect the central nervous system. T. solium tapeworm infection is endemic in much of Peru, but there are scarce data on the prevalence in many rural highland communities where it is likely to be hyper-endemic. Peace Corps Volunteers live and work in these communities; however, to our knowledge, they have not been used to facilitate public health research. We utilized Peace Corps Volunteers to estimate the prevalence of T. solium tapeworm infection in seven rural communities in northern Peru. A convenience non-random sampling frame was used. Peace Corps Volunteers facilitated the collection of stool samples (N = 2,328), which were analyzed by sedimentation and microscopy. Niclosamide treatment and purgation preceded species identification, which was done by PCR-REA. Taenia sp. egg-positive stool samples were found in three of the seven communities we surveyed. The overall prevalence of Taenia sp. egg positivity was 2.1% (49/2,328) (95% CI = 1.6-2.8%) with prevalence up to 4.3% (42/977) (95% CI = 3.1-5.8%) by community. All 34 of the specimens tested by PCR-REA were T. solium. The overall prevalence of T. solium tapeworm infection was 1.5% (34/2,328) (95% CI = 1.0-2.0%). Prevalence up to 2.9% (28/977) (95% CI = 1.9-4.1%) by community was observed. This study recorded high T. solium tapeworm prevalence, and identified hyper-endemic rural communities. It demonstrates that synergy between researchers and Peace Corps Volunteers can be an effective means to conducting large-scale, community-based studies in remote areas of Peru.

This paper assesses empirically the motives and effectiveness of forex interventions in Peru. While the central bank of Peru states that its forex interventions aim only at containing excessive exchange rate volatility, the results of this paper show that, in practice, the interventions seem to have aimed at “leaning against the wind” as well. The results also show that forex sales, but not forex purchases, react to volatility, indicating asymmetry in the central bank’s reactions to episodes ...

Growth of a manganese nodule from Peru Basin: a radiochemical anatomy
International Nuclear Information System (INIS)
Reyss, J.L.; Lemaitre, N.; Marchig, V.; Southon, J.R.; Nelson, D.E.; Vogel, J.S.
1985-01-01
Attempts have been made to study the entire growth history of a manganese nodule from the northern part of Peru Basin in the Pacific using radiochemical profiles of 230 Th/ 232 Th, 227 Th/ 230 Th and 10 Be/ 9 Be. Combined with the observations on Fe-Mn contents and textural variation, the radiochemical data indicate that the nodule grew more or less concentrically throughout most of its existence since it formed 1.5 my ago, receiving Mn from both bottom water and pore water. This condition appeared to have changed about 180 ky ago when the growth became asymmetric in that the top and bottom sides became fixed in their relative positions on the sea floor. Since then, the bottom side accreted with a fast rate of close to 200 mm/my, apparently fueled by the supply of diagenetically remobilized Mn in pore water from the sediment substrate. In the meantime, the topside accumulated at about 6 mm/my, a value which is in the normal range for deep-sea nodules having their Mn supplied from the hydrogenous source. (author)

To determine the frequency of sports physical activity in the urban population of Peru and to identify the sociodemographic, economic, and environmental factors associated with that activity. This study utilized information collected by the country's National Household Survey (Encuesta Nacional de Hogares) in the second quarter of 1997. That Survey is overseen by Peru's National Institute of Statistics and Informatics (Instituto Nacional de Estadística e Informática). The Survey was based on a probabilistic, multistage sample that was stratified for all the urban areas of the country, which was divided into eight geographic regions: metropolitan Lima, northern coast, central coast, southern coast, northern mountains, central mountains, southern mountains, and jungle. In total, 14 913 homes were visited and 45 319 people at least 15 years of age were interviewed. The frequency of engaging in sports physical activity was classified as daily, every other day, weekly, or occasional. "Regular sports activity" (RSA) was defined as engaging in sports either every day or every other day. The preferences for and obstacles to sports practice were also examined. A descriptive analysis of the levels of RSA was carried out for gender, using the chi-square test. The factors associated with RSA were analyzed through conditional multiple logistic regression and analysis of residuals, multicollinearity, and interactions. The level of significance was set at P jungle (15.3%), central mountains (12.8%), and central coast (12.1%). RSA was least common in two regions: southern mountains (9.7%) and metropolitan Lima (10.6%). The income bracket was not associated with RSA. However, other variables associated indirectly with the socioeconomic level - such as having more formal education, being employed, and having access to the Internet or cable television - and consumption of sports information were significantly and directly associated with RSA. The most frequent barriers to

It is pointed out that there are 3 geographical divisions in Peru including: (1) the foggy coastal strip where rain is infrequent, insolation is low and population is high; (2) the mountainous Andes region with high insolation and many populated high mountain valleys; and (3) the rainy, Amazon basin covered with jungle, and sparcely populated with high but inconsistent insolation. Since there is little competition with other forms of energy, solar energy shows promise. Passive solar heating of buildings, particularly in the Andes region, is described, as well as the use of solar water heaters. Prototypes are described and illustrated. Industrial use of solar heated water in the wool industry as well as solar food drying and solar desalination are discussed. High temperature applications (electrical generators and refrigeration) as well as photovoltaic systems are discussed briefly. It is concluded that social and political factors are holding back the development of solar energy but a start (in the form of prototypes and demonstration programs) is being made. (MJJ)

We are in the second year of fieldwork surveying for Giant Otters in the southeastern rainforest of Peru, in three areas with differing levels of legal protection. While there is some illegal hunting still happening outside the protected areas, the main threat to the otters is badly-conducted tourism. Well-organised tourism can be a promising argument for establishing protected areas like national parks.

Contribution to the Uropodina mites of Peru (Acari: Mesostigmata).
Kontschán, Jenő; Friedrich, Stefan
2017-02-27
Soil dwelling Uropodina mites were collected from a primary lowland rainforest in Amazonian Peru. The species found belong to three different families. A new diagnosis and the type genus of Tetrasejaspidae fam. nov. are given, and the family is recorded from Peru for the first time on the basis of Tetrasejaspis sellnicki Hirschmann, 1973. Two rotundabaloghid mites were collected (Rotundabaloghia (Circobaloghia) magna Hirschmann, 1992 and Rotundabaloghia (Circobaloghia) iquitosensis Hirschmann, 1992), both already reported from Peru. A new species (Origmatrachys peruensis sp. nov.) from the family Trachyuropodidae was collected in large numbers from soil, and is described on the basis of females, males, nymphs and larvae. This is the first description of the protonymphs and larvae of Origmatrachys. The new species differs from the previously described ones in the basis of sculptural pattern of dorsal, ventral, sternal shields and the length of the setae in the central part of the dorsal shield. A new key to the known adults and deutonymphs of Origmatrachys is given.

The Santa Rita B archaeological site is in the Chao Valley, approximately 65 km southeast of Trujillo, northern Peru. Location of Santa Rita B at the emergence of several drainages from the Andean cordillera is an important factor in the almost continuous occupation of the site over the past 3,000 years. Mineral resources are abundant throughout the Andes; however, the north coast of Peru was an important center for pre-Columbian mining, metallurgy, and craftsmanship. Success of the Chavin, Moche, Chimu, and other north coast cultures is directly related to the availability and exploitation of mineral and energy resources that include: gold (?silver), as electrum, mainly from placers, and copper from local oxide and carbonate occurrences and from sulfides related to copper porphyry occurrences in the cordillera. An alloy of these three metals is referred to as tumbaga, which is the primary material for Andean metalcraft. Anthracite was used for mirrors by north coast cultures and is available near Rio Chicama, Rio Santa, and east of Santa Rita B. These outcrops are a part of the Alto Chicama, Peru's largest coalfield, which extends from Rio Chicama, in the north, for 200 km southward to Rio Santa. Charcoal from the algorrobo tree and llama dung are considered to be the common pre-Columbian energy sources for cooking and metalwork; however, availability and the higher heat content of anthracite indicate that it was used in metallurgical applications. Bitumen is available from petroleum seeps near Talara, north of the study area, and may have been used as glue or as cement. Hematite, goethite, limonite, and manganese oxides from clay-altered volcanic rock may have provided color and material for ceramics. Guano from the Islas Gua?apes, Chinchas, and Ballestas was used as fertilizer for cotton and other crops.

Full Text Available La neurocisticercosis, infección del sistema nervioso humano por el estadio larvario de la Taenia solium, es una causa importante de epilepsia y otras manifestaciones neurológicas en el Perú y en la mayoría de países en desarrollo. Desde 1987, el Grupo de Trabajo en Cisticercosis en Perú ha desarrollado una serie de estudios epidemiológicos que han llevado a estimar el impacto y entender la transmisión de la Taenia solium, y que posteriormente se aplicaron al diseño y ejecución de un programa de control en Tumbes, en la costa norte del país. En este artículo se revisan los principales hallazgos epidemiológicos, así como las líneas generales del programa de eliminación y las herramientas utilizadas. Los avances en el control de la teniasis/cisticercosis en nuestro país abren el camino hacia su eliminación y eventual erradicación.Neurocysticercosis, the infection of the human central nervous system by the larval stage of the cestode Taenia solium, is an important cause of epilepsy and other neurological manifestations in Peru and most developing countries. Since 1987, the Cysticercosis Working Group in Peru has performed a series of epidemiological studies which led to estimate the impact and to better understand the transmission of Taenia solium. This information was later applied to the design and execution of a control program in Tumbes, in the Northern Coast of Peru. This paper reviews the main epidemiological findings, as well as the conceptual framework of the elimination program and the tools used. Advances in the control of taeniasis/cysticercosis in our country open the road towards its elimination and potential eradication.

Holocene vegetation history from fossil rodent middens near Arequipa, Peru
Holmgren, C.A.; Betancourt, J.L.; Rylander, K.A.; Roque, J.; Tovar, O.; Zeballos, H.; Linares, E.; Quade, Jay
2001-01-01
Rodent (Abrocoma, Lagidium, Phyllotis) middens collected from 2350 to 2750 m elevation near Arequipa, Peru (16??S), provide an ???9600-yr vegetation history of the northern Atacama Desert, based on identification of >50 species of plant macrofossils. These midden floras show considerable stability throughout the Holocene, with slightly more mesophytic plant assemblages in the middle Holocene. Unlike the southwestern United States, rodent middens of mid-Holocene age are common. In the Arequipa area, the midden record does not reflect any effects of a mid-Holocene mega drought proposed from the extreme lowstand (100 m below modern levels, >6000 to 3500 yr B.P.) of Lake Titicaca, only 200 km east of Arequipa. This is perhaps not surprising, given other evidence for wetter summers on the Pacific slope of the Andes during the middle Holocene as well as the poor correlation of summer rainfall among modern weather stations in the central AndesAtacama Desert. The apparent difference in paleoclimatic reconstructions suggests that it is premature to relate changes observed during the Holocene to changes in El Nin??o Southern Oscillation modes. ?? 2001 University of Washington.

Seroprevalence and risk factors for Taenia solium cysticercosis in rural pigs of northern Peru.
Directory of Open Access Journals (Sweden)
César M Jayashi
Full Text Available Taenia solium is a cestode parasite that causes cysticercosis in both humans and pigs. A serological survey was undertaken to assess the seroprevalence and risk factors associated with porcine cysticercosis in the rural district of Morropon, Peru. Pigs aged between 2 and 60 months were assessed by the Enzyme-linked Immunoelectrotransfer blot (EITB assay to determine their serological status against porcine cysticercosis in a cross-sectional study. A total of 1,153 pigs were sampled. Porcine seroprevalence was 45.19% (42.31-48.06. The information about the animals and households was analyzed and risk factors associated with seroprevalence were determined by a multivariate logistic regression analysis. In the porcine population, the risk of being seropositive increased by 7% with every month of age (OR 1.07, 95% CI 1.05-1.09, and by 148% for pigs living in East Morropon (OR 2.48, 95% CI 1.82-3.37. Whereas, the presence of latrines in a household decreased the risk of being seropositive by 49% (OR 0.51; 95% CI 0.39-0.67. Sex and rearing system did not represent either risk or protective factors associated with the seroprevalence of porcine cysticercosis. The findings of this study could be used for further development of control programs that might focus on similar population groups within rural communities of developing countries where cysticercosis is endemic.

The Ilo batholith (17°00 - 18°30 S) crops out in an area of about 20 by 100 km, along the coast of southern Peru. This batholith is emplaced into the ‘Chocolate‘ Formation of late Permian to middle Jurassic age, which consists of more than 1000 m of basaltic and andesitic lavas, with interbedded volcanic agglomerates and breccias. The Ilo Batholith is considered to be a rarely exposed fragment of the Jurassic arc in Peru. Our aim is to reconstruct the magmatic evolution of this batholith, and place it within the context of long-lasting magma genesis along the active Andean margin since the Paleozoic. Sampling for dating and geochemical analyses was carried out along several cross sections through the batholith that were exposed by post-intrusion eastward tilting of 20-30°. Sparse previous work postulates early to middle Jurassic and partially early Cretaceous emplacement, on the basis of conventional K/Ar and 40Ar/39Ar dating methods in the Ilo area. Twenty new U-Pb zircon ages (LA-ICP-MS and CA-ID-TIMS) accompanied by geochemical data suggests the Ilo batholith formed via the amalgamation of middle Jurassic and early Cretaceous, subduction-related plutons. Preliminary Hf isotope studies reveal a primitive mantle source for middle Jurassic intrusions. Additional Sr, Nd and Hf isotope analyses are planned to further resolve the source regions of different pulses of plutonic activity. We strongly suggest that batholith emplacement was at least partly coeval with the emplacement of the late Permian to middle Jurassic Chocolate Formation, which was deposited in an extensional tectonic regime. Our age results and geochemical signature fit into the scheme of episodic emplacement of huge amounts of subduction related magmatism that is observed throughout the whole Andean event, particularly during the middle Jurassic onset of the first Andean cycle (southern Peru, northern Chile and southern Argentina). Although the exact geodynamic setting remains to be precisely

2016-01-01
As a group, transwomen in Peru have the highest prevalence of HIV (>20%) in the country, but they have little access to HIV prevention, testing and care services. Until recently, Peru's national HIV programme did not recognize transwomen and had remained essentially static for decades. This changed in December 2014, when the Ministry of Health expressed its commitment to improve programming for transwomen and to involve transwomen organizations by prioritizing the development of a "Targeted Strategy Plan of STIs/HIV/AIDS Prevention and Comprehensive Care for Transwomen." A policy dialogue between key stakeholders - Peru's Ministry of Health, academic scientists, civil society, transgender leaders and international agencies - created the conditions for a change in Peru's national HIV policy for transwomen. Supported by the effective engagement of all sectors, the Ministry of Health launched a plan to provide comprehensive HIV prevention and care for transwomen. The five-year plan includes new national guidelines for HIV prevention, care and support, and country-level investments in infrastructure and equipment. In addition to new biomedical strategies, the plan also incorporates several strategies to address structural factors that contribute to the vulnerability of transwomen. We identified three key factors that created the right conditions for this change in Peru's HIV policy. These factors include (1) the availability of solid evidence, based on scientific research; (2) ongoing efforts within the transwomen community to become better advocates of their own rights; and (3) a dialogue involving honest discussions between stakeholders about possibilities of changing the nation's HIV policy. The creation of Peru's national plan for HIV prevention and care for transwomen shows that long-term processes, focused on human rights for transwomen in Peru, can lead to organizational and public-policy change.

Implications of raising cigarette excise taxes in Peru
Directory of Open Access Journals (Sweden)
Martin Gonzalez-Rozada
Full Text Available ABSTRACT Objective To assess how raising cigarette excise taxes in Peru might impact cigarette consumption, and to determine if higher taxes would be regressive. Methods Total demand price elasticity was estimated by income groups using two datasets: quarterly time-series data from 1993 – 2012 and data from a cross-sectional survey of income and expenses conducted in 2008 – 2009 . A functional form of the cigarette demand in Peru was specified using the quarterly data set, and the demand price elasticity was estimated for the short and long run. Using the second data set and Deaton methodology, the implementation of elasticity estimation and by groups’ elasticity was done in a two-step procedure. Results Demand price elasticity was −0.7, implying that a 10% price increase via a new tax would reduce consumption by 7%. Demand price elasticity estimations by income group suggested that poorer families are not more price sensitive than richer ones, which implies that increasing cigarette taxes could be regressive. Conclusions Increasing cigarette taxes is the most efficient policy for inducing a reduction in smoking. However, in the case of Peru, an increase in cigarette taxes could be regressive.

[The national health system in Peru].
Sánchez-Moreno, Francisco
2014-01-01
In 1975, a group of professionals in Peru who were experts on national health systems began a process that led the country to be the first in South America to initiate a modern organization of the health system. This pioneering development meant that the creation of the National Health Services System [in Peru] in 1978 occurred before the health system reforms in Chile (1980), Brazil (1990), Colombia (1993), and Ecuador (2008). This encouraging start has had permanent reformist fluctuations since then, with negative development because of the lack of a State policy. Current features of the Peruvian system are inefficient performance, discontinuity, and lack of assessment, which creates a major setback in comparison with other health systems in America. In the 21st century, significant technical efforts have been missed to modernize the system and its functions. The future is worrying and the role of new generations will be decisive.

In Ecuador and Peru, geochemical information from Pacific coastal rivers is limited and scarce. Here, we present an unedited database of major element concentrations from five HYBAM observatory stations monitored monthly between 4 and 10 years, and the discrete sampling of 23 Andean rivers distributed along the climate gradient of the Ecuadorian and Peruvian Pacific coasts. Concentration (C) vs. discharge (Q) relationships of the five monitored basins exhibit a clear dilution behavior for evaporites and/or pyrite solutes, while the solute concentrations delivered by other endmembers are less variable. Spatially, the annual specific fluxes for total dissolved solids (TDS), Ca2+, HCO3-, K+, Mg2+, and SiO2 are controlled on the first order by runoff variability, while Cl-, Na+ and SO42- are controlled by the occurrence of evaporites and/or pyrite. The entire Pacific basin in Ecuador and Peru exported 30 Mt TDS·yr-1, according to a specific flux of ∼70 t·km-2·yr-1. This show that, even under low rainfall conditions, this orogenic context is more active, in terms of solute production, than the global average.

Full Text Available Organizations need well trained employees in order to maintain a competitive advantage. The purpose of this paper is to describe current training practices in Peru and to provide recommendations for improving organizational performance. This paper also aims to set priorities for future research work. Human capital theory and contributions on need assessment, and training planning, implementation and evaluation served as theoretical framework. This is a cross-sectional, exploratory study that used information from surveys conducted in 24 Peru-vian companies. The findings reveal a strong interest in training, particularly with regard to the improvement of competencies, preference for face-to-face training, and the use of reaction evaluation methods. The recommendations include, among others, improving the provisions for internal support, policies, technology, behavioral evaluation, and resources.

An economic evaluation of Peru's liquefied natural gas export policy
International Nuclear Information System (INIS)
Leung, Leonard; Jenkins, Glenn P.
2014-01-01
Peru's Camisea gas fields hold nearly 90% of the country's natural gas reserves. In the 1990s, the government had a policy to prioritize Camisea gas for domestic consumption. The revocation of this policy in the 2000s allowed private developers to export 40% of Camisea's proven reserves, equivalent to one third of Peru's total. This USD 3.9 billion liquefied natural gas (LNG) export project boasts the largest single foreign direct investment in Peru's history. A major component of the financing was granted by international financial institutions on economic grounds. While the project was expected to yield a substantial return to private investors, the export of one third of Peru's total proven natural gas reserves is not in line with its long-term interests. We undertake cost–benefit analyses for a series of scenarios, starting with the project's formative stage in the mid-2000s, and then in 2012, two years after it began its commercial operation. In all cases, Peru does not have sufficient reserves to warrant export, and the economic costs far exceed the benefits. This policy of LNG exports should not have been approved by the government, nor should the loans have been granted by international financial institutions to make it possible. - Highlights: • Peru's Liquefied Natural Gas project is creating an economic loss to the country. • Results of our analyses are robust for all scenarios considered. • The present value of the cost of replacing exported energy far exceeds tax revenue. • Projects cannot be approved based only on immediate benefits. • The potential opportunity costs of projects must be considered

Arboviral diseases are one of the most common causes of acute febrile illness (AFI) and a significant health problem in South America. In Peru, laboratory etiologic identification of these infections occurs in less than 50% of cases, leading to underdiagnoses of important emerging arboviruses. To assess the prevalence of the Dengue (DENV), Oropouche (OROV), Chikungunya (CHIKV), Mayaro (MAYV) and Zika (ZIKV) viruses in patients with acute febrile illness from Puerto Maldonado (Peru). Serum samples were obtained from patients with AFI during January 2016 to March 2016. A total of 139 specimens were analyzed for the presence of DENV, OROV, CHIKV, MAYV, and ZIKV using polymerase chain reaction (PCR). CHIKV in 9.4% and OROV in 8.6% were the most prevalent arboviruses, followed by DENV and ZIKV, with a prevalence of 6.5% and 5%, respectively. Among all patients, the most common symptoms accompanying fever were headaches 79.9%, muscle pain 65.5% and joint pain 63.3%. During this short 3-month period, 4 arboviruses were detected by PCR, CHIKV and OROV being the most common arboviruses in Puerto Maldonado (Peru). Thus, it is crucial to include OROV detection in the national health surveillance. Furthermore, the etiologic clinical diagnosis of arboviral infections is not possible due to the low specificity of symptoms; therefore an increase of cases confirmed by molecular diagnostic methods will enhance arboviral surveillance in Peru.

Our genetic analyses of uncharacterized bunyaviruses isolated in Peru identified a possible reassortant virus containing small and large gene segment sequences closely related to the Caraparu virus and a medium gene segment sequence potentially derived from an unidentified group C orthobunyavirus. Neutralization tests confirmed serologic distinction among the newly identified virus and the prototype and Caraparu strains. This virus, named Itaya, was isolated in 1999 and 2006 from febrile patients in the cities of Iquitos and Yurimaguas in Peru. The geographic distance between the 2 cases suggests that the Itaya virus could be widely distributed throughout the Amazon basin in northeastern Peru. Identification of a new Orthobunyavirus species that causes febrile disease in humans reinforces the need to expand viral disease surveillance in tropical regions of South America. PMID:25898901

Anopheles darlingi is a major vector for malaria in Central and South America. Behavioral, ecological, genetic, and morphologic variability has been observed across its wide distribution. Recent studies have documented that 2 distinct genotypes exist for An. darlingi: a northern lineage (Belize, Guatemala, Colombia, Venezuela, and Panama) and a southern lineage (Amazonia and southern Brazil). In order to determine if these genotypes exhibited different behavioral traits, entrance and exit movement patterns between 2 field populations of An. darlingi that represented each genotype were evaluated using experimental huts. The Belize population exhibited bimodal entrance, with peak entry occurring between 7:00-8:00 p.m. and 5:00-6:00 a.m. and peak exiting occurring between 7:00-8:00 p.m. The Peru population exhibited unimodal entrance, with peak entry occurring between 10:00-11:00 p.m. and peak exiting occurring between 11:00-12:00 a.m. with a secondary smaller peak at 2:30 a.m. Entrance and exit behavioral patterns were significantly different between the Belize and Peru populations of An. darlingi (log-rank [Mantel-Cox] P < 0.001). Information from the present study will be used in the future to determine if there is a correlation between genotype and host-seeking behavior and can be used in the present for regional vector risk assessment.

Three new species of Neofidelia (Hymenoptera: Apoidea: Megachilidae) from Northern Chile.
Dumesh, Sheila; Packer, Laurence
2013-02-01
Neofidelia apacheta Dumesh and Packer, sp. nov., N. camanchaca Dumesh and Packer, sp. nov., and N. submersa Dumesh and Packer, sp. nov. are described from northern Chile. Neofidelia apacheta is known from large numbers of specimens and localities at moderately high elevation (1600-3200m). Neofidelia camanchaca is only known from the ho-lotype male. Neofidelia submersa is known from the holotype male and a pair of paratypes in poor condition, all from a coastal fog oasis. Comparisons are made with the two previously described species of the genus. The collection of N. apa-cheta from so far north in Chile suggests that Neofidelia is likely to be found in southern Peru. A key for the five species of the genus is provided.

An Ectopic Case of Tunga spp. Infection in Peru
Maco, Vicente; Maco, Vicente P.; Gotuzzo, Eduardo
2010-01-01
Tungiasis is a neglected ectoparasitism of impoverished areas in South America and sub-Saharan Africa. The sand flea Tunga spp. preferably infests the soles and the periungueal and interdigital regions of the feet. Ectopic tungiasis is rare, even in highly endemic areas. We describe a case of an indigenous patient in Peru who presented with a nodular lesion in the extensor aspect of the knee and whose biopsy was compatible with Tunga spp. This is the first documented case of knee tungiasis in an endemic country. The historical, clinical, histological, and current epidemiological aspects of tungiasis in Peru are discussed here. PMID:20519602

Venezuelan equine encephalitis virus (VEEV) has been responsible for hundreds of thousands of human and equine cases of severe disease in the Americas. A passive surveillance study was conducted in Peru, Bolivia and Ecuador to determine the arboviral etiology of febrile illness. Patients with suspected viral-associated, acute, undifferentiated febrile illness of Peru, and more recently (2005), in Madre de Dios, Peru. We performed phylogenetic analyses with VEEV from Bolivia, Ecuador and Peru and compared their relationships to strains from other parts of South America. We found that VEEV subtype ID Panama/Peru genotype is the predominant one circulating in Peru. We also demonstrated that VEEV subtype ID strains circulating in Ecuador belong to the Colombia/Venezuela genotype and VEEV from Madre de Dios, Peru and Cochabamba, Bolivia belong to a new ID genotype. In summary, we identified a new major lineage of enzootic VEEV subtype ID, information that could aid in the understanding of the emergence and evolution of VEEV in South America.

Molecular Epidemiology and Genetic Variation of Pathogenic Vibrio parahaemolyticus in Peru
Gavilan, Ronnie G.; Zamudio, Maria L.; Martinez-Urtaza, Jaime
2013-01-01
Vibrio parahaemolyticus is a foodborne pathogen that has become a public health concern at the global scale. The epidemiological significance of V. parahaemolyticus infections in Latin America received little attention until the winter of 1997 when cases related to the pandemic clone were detected in the region, changing the epidemic dynamics of this pathogen in Peru. With the aim to assess the impact of the arrival of the pandemic clone on local populations of pathogenic V. parahaemolyticus in Peru, we investigated the population genetics and genomic variation in a complete collection of non-pandemic strains recovered from clinical sources in Peru during the pre- and post-emergence periods of the pandemic clone. A total of 56 clinical strains isolated in Peru during the period 1994 to 2007, 13 strains from Chile and 20 strains from Asia were characterized by Multilocus Sequence Typing (MLST) and checked for the presence of Variable Genomic Regions (VGRs). The emergence of O3:K6 cases in Peru implied a drastic disruption of the seasonal dynamics of infections and a shift in the serotype dominance of pathogenic V. parahaemolyticus. After the arrival of the pandemic clone, a great diversity of serovars not previously reported was detected in the country, which supports the introduction of additional populations cohabitating with the pandemic group. Moreover, the presence of genomic regions characteristic of the pandemic clone in other non-pandemic strains may represent early evidence of genetic transfer from the introduced population to the local communities. Finally, the results of this study stress the importance of population admixture, horizontal genetic transfer and homologous recombination as major events shaping the structure and diversity of pathogenic V. parahaemolyticus.

Full Text Available BACKGROUND: Currently, there is a paucity of data regarding human adenovirus (HAdv circulation in Andean regions of South America. To address this shortcoming, we report the clinical, phylogenetic, and epidemiologic characteristics of HAdv respiratory tract infection from a large sentinel surveillance study conducted among adults and children in Peru. METHODS/PRINCIPAL FINDINGS: Oropharyngeal swabs were collected from participants visiting any of 38 participating health centers, and viral pathogens were identified by immunofluorescence assay in cell culture. In addition, molecular characterization was performed on 226 randomly selected HAdv samples. Between 2000 and 2010, a total of 26,375 participants with influenza-like illness (ILI or severe acute respiratory infection (SARI were enrolled in the study. HAdv infection was identified in 2.5% of cases and represented 6.2% of all viral pathogens. Co-infection with a heterologous virus was found in 15.5% of HAdv cases. HAdv infection was largely confined to children under the age of 15, representing 88.6% of HAdv cases identified. No clinical characteristics were found to significantly distinguish HAdv infection from other respiratory viruses. Geographically, HAdv infections were more common in sites from the arid coastal regions than in the jungle or highland regions. Co-circulation of subgroups B and C was observed each year between 2006 and 2010, but no clear seasonal patterns of transmission were detected. CONCLUSIONS/SIGNIFICANCE: HAdv accounted for a significant fraction of those presenting with ILI and SARI in Peru and tended to affect the younger population disproportionately. Longitudinal studies will help better characterize the clinical course of patients with HAdv in Peru, as well as determine the role of co-infections in the evolution of illness.

Diagnostic overview of the illegal trade in primates and law enforcement in Peru.
Shanee, Noga; Mendoza, A Patricia; Shanee, Sam
2017-11-01
Peru has one of the richest primate faunas of any country. The illegal trade in wild primates is one of the largest threats to this fauna in Peru. We characterize the illegal trade in primates through empirical and ethnographic data. We collected data from traffic routes and centers throughout Peru and evaluate current efforts to combat this traffic. Based on our findings from 2,070 instances of wildlife crime involving 6,872 primates, we estimate the domestic trade in primates for pets and bushmeat in Peru in the hundreds of thousands per year, with the larger bodied Atelidae facing the highest direct consequences. We found that government authorities lack sufficient staff, capacity, resources, infrastructure, and protocols to efficiently combat illegal trade in primates. Also, the complicated legal framework and lack of cooperation and antagonism with the public further limit these efforts. Wildlife authorities in Peru are able to confiscate only a fraction of primates traded and mostly intervene in cases of private pet owners rather than traffickers. We estimate that the current rate of illegal trade in primates is comparable to levels of trade prior to the 1973 ban on primates' exportation. The combination of direct observations on primate trade and ethnographic data allows a comprehensive look at primate trade in Peru. We call upon decision makers and international funders to channel their efforts toward "on the ground" actions such as increasing the ability of the authorities to act, giving them "in action" training in law enforcement and establishing strict control measures against corruption.

This work explores the effects of European contact on Andean foodways in the Lambayeque Valley Complex, north coast Peru. We test the hypothesis that Spanish colonization negatively impacted indigenous diet. Diachronic relationships of oral health were examined from the dentitions of 203 late-pre-Hispanic and 175 colonial-period Mochica individuals from Mórrope, Lambayeque, to include observations of dental caries, antemortem tooth loss, alveolar inflammation, dental calculus, periodontitis, and dental wear. G-tests and odds ratio analyses across six age classes indicate a range of statistically significant postcontact increases in dental caries, antemortem tooth loss, and dental calculus prevalence. These findings are associated with ethnohistoric contexts that point to colonial-era economic reorganization which restricted access to multiple traditional food sources. We infer that oral health changes reflect creative Mochica cultural adjustments to dietary shortfalls through the consumption of a greater proportion of dietary carbohydrates. Simultaneously, independent skeletal indicators of biological stress suggest that these adjustments bore a cost in increased nutritional stress. Oral health appears to have been systematically worse among colonial women. We rule out an underlying biological cause (female fertility variation) and suggest that the establishment of European gender ideologies and divisions of labor possibly exposed colonial Mochica women to a more cariogenic diet. Overall, dietary change in Mórrope appears shaped by local responses to a convergence of colonial Spanish economic agendas, landscape transformation, and social changes during the postcontact transition in northern Peru. These findings also further the understandings of dietary and biocultural histories of the Western Hemisphere. (c) 2009 Wiley-Liss, Inc.

Astrology in seventeenth-century Peru.
Brosseder, Claudia
2010-06-01
This article discusses three aspects of the history of astrology in seventeenth-century Peru that are of larger interest for the history of science in Latin America: Creole concerns about indigenous idolatry, the impact of the Inquisition on natural philosophy, and communication between scholars within the Spanish colonies and the transatlantic world. Drawing mainly on the scholars Antonio de la Calancha, Juan de Figueroa, and Ruiz de Lozano, along with several Jesuits, the article analyzes how natural and medical astrology took shape in Peru and how they fostered astronomical investigations of the southern skies. While natural and medical astrology, showing New and Old World influences, oscillated between orthodoxy and heterodoxy, and between scholasticism and new science, judicial astrology remained undeveloped. Toward the end of the seventeenth century the discourse about astrology took an unexpected turn, reflecting a newly invigorated moral and Christian reading of the heavens that was in part a response to a deep-rooted dissatisfaction with the failure of the extirpation of idolatry campaigns. Inscribing divine and cardinal virtues, the Virgin Mary, Christian saints, and Greco-Roman allegories into the heavens was considered a way to finally solve the problem of idolatry and to convey Creole greatness.

Although age constraints on crustal deformation and sediment accumulation prove critical to testing hypotheses of orogenic plateau construction, a common lack of marine facies, volcanic tuffs, and suitable fossils hinders many attempts at chronological reconstructions. A series of elevated retroarc basins along the axis of the Andean orogenic belt provide opportunities to define the timing of deformation and transformation from foreland to hinterland basin configurations. In this study, we present new U-Pb ages of detrital zircons in the Ayaviri intermontane basin of southern Peru (~4 km elevation) in the northern part of the central Andean (Altiplano) plateau. Nearly all sandstone samples show strong unimodal U-Pb age peaks (generally defined by > 5-50 zircons), suggesting these age peaks represent syndepositional volcanism and can be regarded as accurate estimates of true depositional (stratigraphic) age. Integration of these ages with structural and stratigraphic relationships demonstrate the utility of zircon U-Pb geochronology in defining both (1) the timing of basin partitioning and (2) the pace of sediment accumulation. (1) U-Pb ages for several sandstone samples from growth-strata packages associated with two basin-bounding faults reveal structural partitioning of the Ayaviri basin from late Oligocene to Miocene time. In the north, displacement along the southwest-directed Ayaviri thrust fault commenced in late Oligocene time (~28-24 Ma), inducing initial structural partitioning of an upper Eocene-Oligocene, > 5 km thick succession potentially representing an early Andean retroarc foreland basin. In the south, the Ayaviri basin was further disrupted by initial displacement along the northeast-directed Pasani thrust fault in early to middle Miocene time (~18-15 Ma). (2) Additional U-Pb analyses from the Ayaviri basin fill help delimit the long-term rates of sedimentation, suggesting relatively short-lived (< 5 Myr) pulses of accelerated accumulation. Rapid

Molecular epidemiology of American/Asian genotype DENV-2 in Peru.
Cruz, Cristhopher D; Forshey, Brett M; Juarez, Diana S; Guevara, Carolina; Leguia, Mariana; Kochel, Tadeusz J; Halsey, Eric S
2013-08-01
During the past decade, countries in South America have reported dengue hemorrhagic fever (DHF) associated with American/Asian genotype of dengue virus serotype 2 (DENV-2). DENV-2 strains have been associated with large outbreaks of dengue fever and DHF in numerous regions of Peru since the mid-1990s, but studies to address the origins, distribution, and genetic diversity of DENV-2 strains have been limited. To address this knowledge gap, we sequenced the envelope gene region of DENV-2 isolates from Peru, Ecuador, Paraguay, and Bolivia. Sequences were aligned and compared to a global sample of DENV-2 viruses. Phylogenetic analysis confirmed the circulation of two DENV-2 genotypes in Peru: American (prior to 2001) and American/Asian (2000 to present). American/Asian genotype variants can be classified into two lineages, and these were introduced into Peru from the north (Ecuador, Colombia, and/or Venezuela) and the east (Brazil and Bolivia). American/Asian lineage II replaced lineage I after 2009. We estimate the time to the most recent common ancestor for American/Asian DENV-2 genotype in the Americas was in 1980, and 1984 and 1989 for lineages I and II, respectively. In light of evidence for increased virulence of lineage II of American/Asian DENV-2, our results support the need for continuous monitoring for the emergence of new DENV genotypes that may be associated with severe disease.

Objectives In Peru, a country with constrained health resources, breast cancer control is characterized by late stage treatment and poor survival. To support breast cancer control in Peru, this study aims to determine the cost-effectiveness of different breast cancer control interventions relevant for the Peruvian context. Methods We performed a cost-effectiveness analysis (CEA) according to WHO-CHOICE guidelines, from a healthcare perspective. Different screening, early detection, palliative, and treatment interventions were evaluated using mathematical modeling. Effectiveness estimates were based on observational studies, modeling, and on information from Instituto Nacional de Enfermedades Neoplásicas (INEN). Resource utilizations and unit costs were based on estimates from INEN and observational studies. Cost-effectiveness estimates are in 2012 United States dollars (US$) per disability adjusted life year (DALY) averted. Results The current breast cancer program in Peru ($8,426 per DALY averted) could be improved through implementing triennial or biennial screening strategies. These strategies seem the most cost-effective in Peru, particularly when mobile mammography is applied (from $4,125 per DALY averted), or when both CBE screening and mammography screening are combined (from $4,239 per DALY averted). Triennially, these interventions costs between $63 million and $72 million per year. Late stage treatment, trastuzumab therapy and annual screening strategies are the least cost-effective. Conclusions Our analysis suggests that breast cancer control in Peru should be oriented towards early detection through combining fixed and mobile mammography screening (age 45-69) triennially. However, a phased introduction of triennial CBE screening (age 40-69) with upfront FNA in non-urban settings, and both CBE (age 40-49) and fixed mammography screening (age 50-69) in urban settings, seems a more feasible option and is also cost-effective.

In Portovelo in southern Ecuador, 87 gold processing centers along the Puyango-Tumbes River produce an estimated 6 tonnes of gold per annum using a combination of mercury amalgamation and/or cyanidation and processing poly-metallic ores. We analysed total Hg, Hg isotopes, total arsenic, cadmium, copper, lead and zinc in water and sediment along the Puyango in 2012-2014. The highest total mercury (THg) concentrations in sediments were found within a 40 km stretch downriver from the processing plants, with levels varying between 0.78-30.8 mg kg-1 during the dry season and 1.80-70.7 mg kg-1 during the wet season, with most concentrations above the CCME (Canadian Council of Ministers of the Environment) Probable Effect Level (PEL) of 0.5 mg kg-1. Data from mercury isotopic analyses support the conclusion that mercury use during gold processing in Portovelo is the source of Hg pollution found downstream in the Tumbes Delta in Peru, 160 km away. The majority of the water and sediment samples collected from the Puyango-Tumbes River had elevated concentrations of, arsenic, cadmium, copper, lead and zinc exceeding the CCME thresholds for the Protection of Aquatic Life. At monitoring points immediately below the processing plants, total dissolved concentrations of these metals exceeded the thresholds by 156-3567 times in surface waters and by 19-740 times in sediment. The results illustrate a significant transboundary pollution problem involving Hg and other toxic metals, amplified by the fact that the Puyango-Tumbes River is the only available water source in the semi-arid region of northern Peru.

Interventions to promote behaviors to reduce sodium intake require messages tailored to local understandings of the relationship between what we eat and our health. We studied local explanations about hypertension, the relationship between local diet, salt intake, and health status, and participants' opinions about changing food habits. This study provided inputs for a social marketing campaign in Peru promoting the use of a salt substitute containing less sodium than regular salt. Qualitative methods (focus groups and in-depth interviews) were utilized with local populations, people with hypertension, and health personnel in six rural villages. Participants were 18-65 years old, 41% men. Participants established a direct relationship between emotions and hypertension, regardless of age, gender, and hypertension status. Those without hypertension established a connection between eating too much/eating fried food and health status but not between salt consumption and hypertension. Participants rejected dietary changes. Economic barriers and high appreciation of local culinary traditions were the main reasons for this. It is the conclusion of this paper that introducing and promoting salt substitutes require creative strategies that need to acknowledge local explanatory disease models such as the strong association between emotional wellbeing and hypertension, give a positive spin to changing food habits, and resist the "common sense" strategy of information provision around the causal connection between salt consumption and hypertension.

2009-04-01
Full Text Available Abstract Background National malaria control programmes must deal with the complex process of changing national malaria treatment guidelines, often without guidance on the process of change. Selecting a replacement drug is only one issue in this process. There is a paucity of literature describing successful malaria treatment policy changes to help guide control programs through this process. Objectives To understand the wider context in which national malaria treatment guidelines were formulated in a specific country (Peru. Methods Using qualitative methods (individual and focus group interviews, stakeholder analysis and a review of documents, a retrospective analysis of the process of change in Peru's anti-malarial treatment policy from the early 1990's to 2003 was completed. Results The decision to change Peru's policies resulted from increasing levels of anti-malarial drug resistance, as well as complaints from providers that the drugs were no longer working. The context of the change occurred in a time in which Peru was changing national governments, which created extreme challenges in moving the change process forward. Peru utilized a number of key strategies successfully to ensure that policy change would occur. This included a having the process directed by a group who shared a common interest in malaria and who had long-established social and professional networks among themselves, b engaging in collaborative teamwork among nationals and between nationals and international collaborators, c respect for and inclusion of district-level staff in all phases of the process, d reliance on high levels of technical and scientific knowledge, e use of standardized protocols to collect data, and f transparency. Conclusion Although not perfectly or fully implemented by 2003, the change in malaria treatment policy in Peru occurred very quickly, as compared to other countries.

Mummified trophy heads from Peru: diagnostic features and medicolegal significance.
Verano, John W
2003-05-01
Several forms of mummified human trophy heads were produced by prehistoric and historic native groups in South America. This paper describes the diagnostic features of trophy heads produced by the Nasca culture of ancient Peru. A growing interest in these mummified heads among collectors of Pre-Columbian art and antiquities has led to their illegal exportation from Peru, in violation of national and international antiquities laws. Requests from the Peruvian government to protect its cultural patrimony led the United States in 1997 to declare these heads as items subject to U.S. import restriction, along with six other categories of human remains. Despite such restrictions, Nasca trophy heads continue to reach private collectors outside of Peru and thus may be encountered by local, state, or federal law enforcement officials unfamiliar with their characteristic features and origin. The objective of this paper is to describe the features that allow Nasca trophy heads to be identified and distinguished from other archaeological and forensic specimens that may be submitted to a forensic anthropologist for identification.

The 1997–1998 El Niño as an unforgettable phenomenon in northern Peru: a qualitative study
Bayer, Angela M.; Danysh, Heather E.; Garvich, Mijail; Gonzálvez, Guillermo; Checkley, William; Alvarez, María; Gilman, Robert H.
2014-01-01
During the 1997–98 El Niño Southern Oscillation (ENSO), Tumbes, Peru received 16 times the annual average rainfall. We explored how Tumbes residents perceived the ENSO’s impact on basic necessities, transport, healthcare, jobs and migration. Forty-five individuals from five rural communities, including those that were isolated and not isolated from the rest of Tumbes during this ENSO, participated in five focus groups and six individuals constructed nutrition diaries. When asked about events in the past twenty years, participants considered the El Niño as a major negative event. Negative effects that were ameliorated quickly were decreased access to transport and healthcare and increased infectious diseases. Residents needed more time to rebuild housing, recover agriculture, livestock and income stability, and return to eating sufficient animal protein. Although large-scale assistance minimized the ENSO’s effects, residents needed more timely support. Residents’ perspectives on their risks to flooding should be considered to generate effective assistance. PMID:24601921

Counterfeit medicines in Peru: a retrospective review (1997-2014).
Medina, Edwin; Bel, Elvira; Suñé, Josep María
2016-04-04
To consolidate and assess information on counterfeit medicines subject to pharmaceutical alerts issued by the Peruvian Medicines Regulatory Authority over 18 years (1997-2014) of health monitoring and enforcement. A retrospective review of drug alerts. A search of the website of the General Directorate of Medicines, Supplies and Drugs (DIGEMID) of the Ministry of Health of Peru for drug alerts issued between 1997 and 2014. Drug alerts related to counterfeit medicines. A total of 669 DIGEMID alerts were issued during the study period, 354 (52.91%) of which cover 1738 cases of counterfeit medicines (many alerts deal with several cases at a time). 1010 cases (58.11%) involved pharmaceutical establishments and 349 (20.08%) involved non-pharmaceutical commercial outlets. In 126 cases (7.25%), counterfeit medicines were seized in an unauthorised trade (without any marketing authorisation); in 253 cases (14.56%) the type of establishment or business associated with the seized product was not identified. Counterfeit medicines are a serious public health problem in Peru. A review of the data cannot determine whether counterfeit medicines in Peru increased during the study period, or if monitoring by different government health agencies highlighted the magnitude of the problem by providing more evidence. The problem is clearly structural, since the majority of cases (58.11% of the total) were detected in legitimate supply chains. Most counterfeit medicines involve staple pharmaceutical products and common dosage forms. Considerable work remains to be done to control the serious problem of counterfeit medicines in Peru.

We report on an interdisciplinary study of ceramic material excavated in 1999 and 2001 at a 1000-year old ceramic and metal production site, located at Huaca Sialupe in the La Leche valley on the north coast of Peru and dating to the Middle Sican period (AD 900-1100). Sherds of Sican red- and blackware, numerous moulds, several kilns and other evidence of pottery making were found. The pottery, in particular, is famous for its fine texture and perfect black surface finish. In addition, some clay lumps and sherds of unfired Sican pottery were excavated. Within the same workshop several large inverted ceramic urns used as furnaces were found together with Middle Sican metal working tools and debris. Various physical methods were applied to investigate this material. The ancient firing procedures could be elucidated by comparing the spectra observed for the ancient sherds with model spectra of laboratory and field fired clay samples. This shows that the fine ware made at Huaca Sialupe was intentionally fired under strongly reducing conditions at temperatures up to 900 o C. Reoxidation at the end of the reducing firing took place only occasionally. Less care was taken in firing moulds used for pottery making.

The IUREP Orientation Phase Mission to Peru believes that the Speculative Resources of that country fall between 6,000 and 11,000 tonnes uranium. There has been no uranium production in Peru and there are no official estimates of uranium resources. Past exploration in Peru (dating from about 1952) has indicated a paucity of valid uranium occurrences and radioactive anomalies. Only recently (1980) have anomalous areas been identified, (Macusani-Picotani). The identified Speculative Resources are mainly in Late Tertiary ignimbrites and associated sediments in the high Andes of southern Peru. Geologically, there are direct parallels between these resources and deposits of the Los Frailes areas of neighbouring Bolivia. Other minor Speculative Resources may be present in calcretes developed from Tertiary volcanogenic sources over the Precambrian in the Pacific Coastal desert of southern Peru but no positive indications have been recognised. Hercynian sub-volcanic granites in the eastern cordillera of southern Peru may have some associated Speculative Resources both intra and extra granitic. No Speculative Potential could be identified in Permo-Triassic or Tertiary post tectonic continental sediments anywhere in Peru. Such potential may exist but further reconnaissance of the continental late Tertiary basins, with positive indications would be required before inclusion of potential in this category. Recent discoveries in the volcanogenic environment of southern Peru have been by carborne, helicopter borne and on on-foot reconnaissance of isolated areas. It is recommended that there be a more systematic, integrated study of the entire volcanic district assisted by volcanic petrographic examination. Assessment of the known occurrences requires immediate subsurface study by drilling and exploration audits to assess their continuity, grade variation and thickness. This phase will be significantly more expensive than previous exploration. Non-core drilling should supplement

Annotated checklist of Solanum L. (Solanaceae for Peru
Directory of Open Access Journals (Sweden)
Tiina Särkinen
2015-04-01
Full Text Available The genus Solanum is among the most species-rich genera both of the Peruvian flora and of the tropical Andes in general. The present revised checklist treats 276 species of Solanum L., of which 253 are native, while 23 are introduced and/or cultivated. A total of 74 Solanum species (29% of native species are endemic to Peru. Additional 58 species occur only in small number of populations outside Peru, and these species are here labelled as near-endemics to highlight the role Peru playes in their future protection. Species diversity is observed to peak between 2500 – 3000 m elevation, but endemic species diversity is highest between 3000 – 3500 m elevation. Cajamarca has the highest number of endemic (29 spp. and total species (130 spp., even when considering the effect of area. Centers of endemic species diversity are observed in provinces of Cajamarca (Cajamarca, Huaraz and Carhuaz (Ancash, and Canta and Huarochirí (Lima. Secondary centres of endemism with high concentrations of both endemics and near-endemics are found in San Ignacio and Cutervo (Cajamarca, Santiago de Chuco (La Libertad, Oxapampa (Pasco, and Cusco (Cusco. Current diversity patterns are highly correlated with collection densities, and further collecting is needed across all areas, especially from Arequipa, Ayacucho, Puno, Ancash, Huánuco, Amazonas and Cajamarca, where high levels of species diversity and endemism are indicated but only a few collections of many species are known.

The societal burden of blindness secondary to retinopathy of prematurity in Lima, Peru.
Dave, Hreem B; Gordillo, Luz; Yang, Zhou; Zhang, Monica S; Hubbard, G Baker; Olsen, Timothy W
2012-10-01
To determine the cost-effectiveness of laser treatment for retinopathy of prematurity (ROP) in Lima, Peru. A cost-of-illness study (in US dollars) to determine the direct cost of treatment, the indirect lifetime cost of blindness, and the quality-adjusted life years. The direct cost of ROP-related treatment was determined by reviewing data retrospectively from a social security sector hospital. The indirect cost was determined using national economic data of Peru published by the Central Information Agency (CIA), including the per capita gross domestic product, the sex-adjusted income distribution, and years spent in the work force. Indirect costs per child that were avoided by treatment were calculated using the known natural history of ROP vs evidence-based treatment. For ROP-related neonatal blindness in Peru, we estimate the total indirect cost saving at $197,753 per child and the direct cost of laser treatment at $2496 per child. The societal lifetime cost saving per child is estimated at $195,257. The mean annual income per educated adult in Peru is $8000 and treating 1 child is equivalent to employing 24 educated Peruvians per year. The generational cost savings for society is approximately $516 million, or the equivalent of 64,500 educated Peruvian work years. The societal burden of blindness far exceeds the costs of treatment per child. Proper screening and treatment of ROP prevents blindness and leads to substantial cost savings for society. Public health policy in Peru and other middle-income countries should consider financial impact when allocating healthcare resources. Copyright © 2012 Elsevier Inc. All rights reserved.

Genotypes and subgenotypes of hepatitis B virus circulating in an endemic area in Peru.
Ramírez-Soto, Max Carlos; Bracho, Maria Alma; González-Candelas, Fernando; Huichi-Atamari, Milagros
2018-01-01
Although hepatitis B virus (HBV) infection is still endemic in Abancay, Peru, two decades after vaccination against hepatitis B started in the area, little is known about the diversity and circulation of genotypes and subgenotypes of the virus. To identify the genotypes and subtypes of HBV circulating in Abancay, complete genome sequences of 11 treatment-naive HBV-infected patients were obtained, and phylogenetic analysis was conducted with these and additional sequences from GenBank. Genotyping revealed the presence of genotype F in all the samples from Abancay. Subgenotype F1b was dominant and only one isolate belonged to subgenotype F4, which represents the first description of this subgenotype in Peru. Phylogenetic analysis revealed that most subgenotype F1b isolates from Peru clustered in a subgroup along with two sequences from Argentina, whereas two clusters with two HBV/F1b sequences each were indicative of recent epidemiological linkage, but only one could be verified by independent data. These results suggest that the HBV subgenotype F1b seems to be the predominant subgenotype in Abancay, Peru.

The high incidence of human hepatocellular carcinoma (HCC) in Peru and the wide use of medicinal plants in this country led us to study the activity against HCC cells in vitro of somes species used locally against liver and digestive disorders. Ethnopharmacological survey: Medicinal plant species with a strong convergence of use for liver and digestive diseases were collected fresh in the wild or on markets, in two places of Peru: Chiclayo (Lambayeque department, Chiclayo province) and Huaraz (Ancash department, Huaraz province). Altogether 51 species were collected and 61 ethanol extracts were prepared to be tested. Biological assessment: All extracts were first assessed against the HCC cell line Hep3B according a 3-step multi-parametric phenotypic assay. It included 1) the evaluation of phenotypic changes on cells by light microscopy, 2) the measurement of the antiproliferative activity and 3) the analysis of the cytoskeleton and mitosis by immunofluorescence. Best extracts were further assessed against other HCC cell lines HepG2, PLC/PRF/5 and SNU-182 and their toxicity measured in vitro on primary human hepatocytes. Ethnopharmacological survey: Some of the species collected had a high reputation spreading over the surveyed locations for treating liver problems, i.e. Baccharis genistelloides, Bejaria aestuans, Centaurium pulchellum, Desmodium molliculum, Dipsacus fullonum, Equisetum bogotense, Gentianella spp., Krameria lapacea, Otholobium spp., Schkuhria pinnata, Taraxacum officinale. Hep3B evaluation: Fourteen extracts from 13 species (Achyrocline alata, Ambrosia arborescens, Baccharis latifolia, Hypericum laricifolium, Krameria lappacea, Niphidium crassifolium, Ophryosporus chilca, Orthrosanthus chimboracensis, Otholobium pubescens, Passiflora ligularis, Perezia coerulescens, Perezia multiflora and Schkuhria pinnata) showed a significant antiproliferative activity against Hep3B cells (IC50≤ 50µg/mL). This was associated with a lack of toxicity on primary

[Social programs and reducing obesity in Peru: reflections from the research].
Diez-Canseco, Francisco; Saavedra-Garcia, Lorena
2017-01-01
In recent decades, overweight or obesity have increased dramatically in middle- and low-income countries; a situation which consolidates chronic non-communicable diseases (NCD) as one of the leading causes of mortality and disability worldwide. Currently, half the people in Peru over the age of 15 years are overweight, and one fifth suffer from obesity. The situation is worsening and increasingly affects people in poverty, who frequently benefit from food supplement programs designed to combat food insecurity and malnutrition. There is an urgent worldwide need to find policies and programs that help fight the problem of obesity at the population level, a task that is still pending. In this article, we review the current epidemic of overweight and obesity in Peru and the world and its most significant consequences and causes, with an emphasis on access to and availability of foods. We describe the largest food supplement programs and synthesize the research on interventions in order to reflect on how their findings might help social programs work as a platform to reduce obesity and prevent NCD in Peru.

The epidemiological profile and trends of road traffic injuries (RTIs) in Peru have not been well-defined, though this is a necessary step to address this significant public health problem in Peru. The objective of this study was to determine trends of incidence, mortality, and fatality of RTIs in Peru during 1973-2008, as well as their relationship to population trends such as economic growth. Secondary aggregated databases were used to estimate incidence, mortality and fatality rate ratios (IRRs) of RTIs. These estimates were standardized to age groups and sex of the 2008 Peruvian population. Negative binomial regression and cubic spline curves were used for multivariable analysis. During the 35-year period there were 952,668 road traffic victims, injured or killed. The adjusted yearly incidence of RTIs increased by 3.59 (95% CI 2.43-5.31) on average. We did not observe any significant trends in the yearly mortality rate. The total adjusted yearly fatality rate decreased by 0.26 (95% CI 0.15-0.43), while among adults the fatality rate increased by 1.25 (95% CI 1.09-1.43). Models fitted with splines suggest that the incidence follows a bimodal curve and closely followed trends in the gross domestic product (GDP) per capita. The significant increasing incidence of RTIs in Peru affirms their growing threat to public health. A substantial improvement of information systems for RTIs is needed to create a more accurate epidemiologic profile of RTIs in Peru. This approach can be of use in other similar low and middle-income settings to inform about the local challenges posed by RTIs.

Full Text Available This article identifies the main variables that explain judicial corruption in Chile, Peru, and Ecuador. Improving the current methodological strategies used to measure judicial corruption and incorporating endogenous and exogenous variables in the model, this article argues that legal training of the judges, respect for the judicial career, and the fragmentation of political power explain different degrees of judicial corruption. Through a comparative diachronic and synchronic research design of Chile, Peru and Ecuador, the article shows institutional designs with more legal steps will be more inclined to illegal payments or other types of judicial corruption.

[Spatial analysis of gestational anemia in Peru, 2015].
Hernández-Vásquez, Akram; Azañedo, Diego; Antiporta, Daniel A; Cortés, Sandra
2017-01-01
To establish regional prevalences of anemia in pregnant women receiving care at public clinics in Peru in 2015 and identify high-prevalence district conglomerates. An ecological study was carried out on data from pregnant women with anemia registered on the Nutritional Status Information System (SIEN) who received care in 7703 public clinics in 2015. Regional and district prevalences of gestational anemia were calculated. District conglomerates with a high prevalence of gestational anemia were identified using the Moran Index. Information was gathered from 311,521 pregnant women distributed in 1638 districts in Peru. The national prevalence of anemia was 24.2% (95% confidence interval [95% CI]: 24.0-24.3%), the rural prevalence was 30.5%, and the urban prevalence was 22.0%. The regions of Huancavelica (45.5%; 95% CI: 44.2-46.7%), Puno (42.8%; 95% CI: 41.9-43.7%), Pasco (38.5%; 95% CI: 36.9-40.0%), Cusco (36.0%; 95% CI: 35.3-36.8%), and Apurímac (32.0%; 95% CI: 30.8-33.1%) had the highest prevalences of anemia. The local Moran Index identified 202 high-priority districts (hot spots) (12.3% of total; 44 urban and 158 rural) located in Ancash, Apurímac, Arequipa, Ayacucho, Cajamarca, Cusco, Huancavelica, Huánuco, Junín, La Libertad, Lima, Pasco, and Puno containing high-prevalence district conglomerates. Gestational anemia in Peru has its highest prevalence rates in rural and southern mountainous areas. The district conglomerates with high prevalence rates of gestational anemia coincide with the areas of high regional prevalence.

Can oral challenge with balsam of Peru predict possible benefit from a low-balsam diet?
Veien, N K; Hattel, T; Laurberg, G
1996-06-01
Previous studies have shown that some patients sensitive to balsams and/or fragrances obtain long-term benefits by following a low-balsam diet, whereas others do not. This study was performed to determine whether a low-balsam diet was a helpful long-term treatment for selected patients sensitive to balsam of Peru and/or a perfume mixture and to determine whether oral challenge with balsam of Peru could predict which balsam-sensitive patients might benefit from a reduction in balsam intake. Questionnaires were sent to 46 patients with positive patch test results to balsam of Peru and/or a perfume mixture and chronic dermatitis of a morphology consistent with endogenous dermatitis who had experienced improvement after 1 to 2 months on a diet intended to reduce the intake of balsams. The questionnaires were mailed 1 to 3 years after the initiation of the diet treatment to inquire about a possible long-term benefit of the diet. Twenty-eight of the 46 patients stated in the questionnaire that they had long-term benefits from the diet treatment. These included 16 of 22 patients who had reacted to a placebo-controlled oral challenge with 1 g balsam of Peru, 3 of 10 who had no reaction or a placebo reaction to the oral challenge, and 9 of 14 who had not been challenged orally. The efficacy of the diet treatment was not correlated to whether the patient had patch test reactivity to either balsam of Peru, the perfume mixture, or both substances. Food items most commonly mentioned by patients as causing aggravation of their symptoms on at least three different occasions were wine, candy, chocolate, cinnamon, curry, citrus fruit, and flavorings. In its present form, the oral challenge procedure with balsam of Peru offers only limited assistance in selecting patients who are likely to benefit from diet treatment.

We report on an interdisciplinary study of ceramic material excavated in 1999 and 2001 at a 1000-year old ceramic and metal production site, located at Huaca Sialupe in the La Leche valley on the north coast of Peru and dating to the Middle Sicán period (AD 900-1100). Sherds of Sicán red- and blackware, numerous moulds, several kilns and other evidence of pottery making were found. The pottery, in particular, is famous for its fine texture and perfect black surface finish. In addition, some clay lumps and sherds of unfired Sicán pottery were excavated. Within the same workshop several large inverted ceramic urns used as furnaces were found together with Middle Sicán metal working tools and debris. Various physical methods were applied to investigate this material. The ancient firing procedures could be elucidated by comparing the spectra observed for the ancient sherds with model spectra of laboratory and field fired clay samples. This shows that the fine ware made at Huaca Sialupe was intentionally fired under strongly reducing conditions at temperatures up to 900°C. Reoxidation at the end of the reducing firing took place only occasionally. Less care was taken in firing moulds used for pottery making.

Phytophthora infestans (Mont.) de Bary, the causal agent of potato late blight, is responsible for tremendous crop losses worldwide. Countries in the northern part of the Andes dedicate a large proportion of the highlands to the production of potato, and more recently, solanaceous fruits such as cape gooseberry (Physalis peruviana) and tree tomato (Solanum betaceum), all of which are hosts of this oomycete. In the Andean region, P. infestans populations have been well characterized in Ecuador and Peru, but are poorly understood in Colombia and Venezuela. To understand the P. infestans population structure in the Northern part of the Andes, four nuclear regions (ITS, Ras, β-tubulin and Avr3a) and one mitochondrial (Cox1) region were analyzed in isolates of P. infestans sampled from different hosts in Colombia and Venezuela. Low genetic diversity was found within this sample of P. infestans isolates from crops within several regions of Colombia and Venezuela, revealing the presence of clonal populations of the pathogen in this region. We detected low frequency heterozygotes, and their distribution patterns might be a consequence of a high migration rate among populations with poor effective gene flow. Consistent genetic differentiation exists among isolates from different regions. The results here suggest that in the Northern Andean region P. infestans is a clonal population with some within-clone variation. P. infestans populations in Venezuela reflect historic isolation that is being reinforced by a recent self-sufficiency of potato seeds. In summary, the P. infestans population is mainly shaped by migration and probably by the appearance of variants of key effectors such as Avr3a.

Solar water heating for small cheese factories in Peru
Energy Technology Data Exchange (ETDEWEB)
Oliveros Donohue, A A
1982-03-01
Plans are described for the implementation of 40 small plants to be used for cheese production. As a start, a demonstration plant has been built in San Juan de Chuquibambilla-Puno, Peru. Design and testing of a flat plate solar collector, to be used for water heating purposes, are described. The cheese making process is discussed. Essentially two pots are required, one at 32/sup 0/C and one at 80/sup 0/. Two flat plate collectors (1.12 m/sup 2/ each) are connected to a 150 l storage tank. Instrumentation and results are discussed. Total efficiency of the process is given as 40%. It is concluded that future installations should consider using biogas digesters and wind driven water pumps in addition to the solar collectors. A brief discussion of the climate, population distribution, and economy of Peru is given. (MJJ)

In Peru, the prevalence and consequences of inhalant abuse appear to be low in the general population and high among marginalized children. Inhalant use ranks third in lifetime prevalence after alcohol and tobacco. Most of the use appears to be infrequent. Among marginalized children, that is, children working in the streets but living at home or children living in the street, the problem of inhalant abuse is a serious problem. Among children working in the streets but living at home, the lifetime prevalence rate for inhalant abuse is high, ranging from 15 to 45 percent depending on the study being cited. For children living in the streets, the use of inhalant is even more severe. As mentioned earlier in this chapter, most of these street children use inhalants on a daily basis. The lack of research on the problem of inhalant abuse is a serious impediment to development of intervention programs and strategies to address this problem in Peru. Epidemiologic and ethnographic research on the nature and extent of inhalant abuse are obvious prerequisites to targeted treatment and preventive intervention programs. The urgent need for current and valid data is underscored by the unique vulnerability of the youthful population at risk and the undisputed harm that results from chronic abuse of inhalants. Nonetheless, it is important to mention several programs that work with street children. Some, such as the Information and Education Center for the Prevention of Drug Abuse, Generation, and Centro Integracion de Menores en Abandono have shelters where street children are offered transition to a less marginal lifestyle. Teams of street educators provide the children with practical solutions and gain their confidence, as well as offer them alternative socialization experiences to help them survive the streets and avoid the often repressive and counterproductive environments typical of many institutions. Most of the children who go through these programs tend to abandon

Chronology of guitarrero cave, peru.
Lynch, T F; Gillespie, R; Gowlett, J A; Hedges, R E
1985-08-30
Dating by accelerator mass spectrometry of wooden artifacts, cord, and charcoal samples from Guitarrero Cave, Peru, supports the antiquity of South America's earliest textiles and other perishable remains. The new dates are consistent with those obtained from disintegration counters and leave little doubt about the integrity of the lower Preceramic layers and their early cultivars. Re-evaluation of the mode of deposition suggests that most of the remains resulted from short-term use of the cave in the eighth millennium B.C., with a possible brief human visit as early as 12,560 years ago.

We studied the phylogeography and plumage variation of the Russet-crowned Warbler (Myiothlypis coronata), from Venezuela to Bolivia, with focus on populations from Ecuador and northern Peru. We analyzed sequences of mitochondrial and nuclear genes, geographic distributions, as well as photographs of specimens deposited at museum collections. Phylogenetic analyses identified three major lineages formed by populations from: Venezuela and Colombia (M. c. regulus), Ecuador and northern Peru (M. elata, M. castaneiceps, M. orientalis, M. c. chapmani), and central Peru and Bolivia (M. c. coronata). We found further population structure within M. c. regulus and M. c. coronata, and population structure and complexity of plumage variation within the Ecuador-northern Peru lineage. Time-calibrated trees estimated that most intraspecific variation originated during the Pleistocene; however, this pattern may not be attributed to an increase in diversification rate during that period. We discuss these results in the context of the importance of geographic-ecological barriers in promoting lineage diversification along the Andes and put forward a preliminary taxonomic proposal for major lineages identified in this study.

Background The epidemiological profile and trends of road traffic injuries (RTIs) in Peru have not been well-defined, though this is a necessary step to address this significant public health problem in Peru. The objective of this study was to determine trends of incidence, mortality, and fatality of RTIs in Peru during 1973–2008, as well as their relationship to population trends such as economic growth. Methods and Findings Secondary aggregated databases were used to estimate incidence, mortality and fatality rate ratios (IRRs) of RTIs. These estimates were standardized to age groups and sex of the 2008 Peruvian population. Negative binomial regression and cubic spline curves were used for multivariable analysis. During the 35-year period there were 952,668 road traffic victims, injured or killed. The adjusted yearly incidence of RTIs increased by 3.59 (95% CI 2.43–5.31) on average. We did not observe any significant trends in the yearly mortality rate. The total adjusted yearly fatality rate decreased by 0.26 (95% CI 0.15–0.43), while among adults the fatality rate increased by 1.25 (95% CI 1.09–1.43). Models fitted with splines suggest that the incidence follows a bimodal curve and closely followed trends in the gross domestic product (GDP) per capita Conclusions The significant increasing incidence of RTIs in Peru affirms their growing threat to public health. A substantial improvement of information systems for RTIs is needed to create a more accurate epidemiologic profile of RTIs in Peru. This approach can be of use in other similar low and middle-income settings to inform about the local challenges posed by RTIs. PMID:24927195

Full Text Available Venezuelan equine encephalitis virus (VEEV has been responsible for hundreds of thousands of human and equine cases of severe disease in the Americas. A passive surveillance study was conducted in Peru, Bolivia and Ecuador to determine the arboviral etiology of febrile illness. Patients with suspected viral-associated, acute, undifferentiated febrile illness of <7 days duration were enrolled in the study and blood samples were obtained from each patient and assayed by virus isolation. Demographic and clinical information from each patient was also obtained at the time of voluntary enrollment. In 2005-2007, cases of Venezuelan equine encephalitis (VEE were diagnosed for the first time in residents of Bolivia; the patients did not report traveling, suggesting endemic circulation of VEEV in Bolivia. In 2001 and 2003, VEE cases were also identified in Ecuador. Since 1993, VEEV has been continuously isolated from patients in Loreto, Peru, and more recently (2005, in Madre de Dios, Peru. We performed phylogenetic analyses with VEEV from Bolivia, Ecuador and Peru and compared their relationships to strains from other parts of South America. We found that VEEV subtype ID Panama/Peru genotype is the predominant one circulating in Peru. We also demonstrated that VEEV subtype ID strains circulating in Ecuador belong to the Colombia/Venezuela genotype and VEEV from Madre de Dios, Peru and Cochabamba, Bolivia belong to a new ID genotype. In summary, we identified a new major lineage of enzootic VEEV subtype ID, information that could aid in the understanding of the emergence and evolution of VEEV in South America.

More prehistoric trepanned crania have been found in Peru than any other location worldwide. We examine trepanation practices and outcomes in Peru over nearly 2000 years from 400 BC to provide a perspective on the procedure with comparison with procedures/outcomes of other ancient, medieval, and American Civil War cranial surgery. Data on trepanation demographics, techniques, and survival rates were collected through the scientific analysis of more than 800 trepanned crania discovered in Peru, through field studies and the courtesy of museums and private collections in the United States and Peru, over nearly 3 decades. Data on procedures and outcomes of cranial surgery ancient, medieval, and during 19th-century through the American Civil war were obtained via a literature review. Successful trepanations from prehistoric times through the American Civil War likely involved shallow surgeries that did not pierce the dura mater. Although there are regional and temporal variations in ancient Peru, overall long-term survival rates for the study series were about 40% in the earliest period (400-200 BC), with improvement to a high of 91% in samples from AD 1000-1400, to an average of 75%-83% during the Inca Period (AD 1400s-1500). In comparison, the average cranial surgery mortality rate during the American Civil war was 46%-56%, and short- and long-term survival rates are unknown. The contrast in outcomes highlights the astonishing success of ancient cranial surgery in Peru in the treatment of living patients. Copyright © 2018 Elsevier Inc. All rights reserved.

[Gestational syphilis and associated factors in public hospitals of Peru during 2000-2010].
Gonzales, Gustavo F; Tapia, Vilma; Serruya, Suzanne J
2014-04-01
To determine the epidemiological profile of gestational syphilis and associated factors in a Peruvian population. The study is a secondary analysis of data obtained from public hospitals in Peru for the 2000-2010 period. 652,636 pregnant women were included from 37 cities and 45 health centers in Peru. The prevalence of gestational syphilis was 0.7%, while 80.7% reported screening for gestational syphilis. The highest prevalence of maternal syphilis is found in the lowland rainforest followed by the highland rainforest. In the three regions of Peru decreased prevalence of gestational syphilis has been seen throughout the years. The prevalence for 2010 are 0.2% on the coast, in the highlands 0.23% and 0.47% in the jungle. The lack of education and prenatal care, high parity, cohabiting or single, and living in the jungle, are associated with having a positive syphilis test. The results suggests that prevalence of gestational syphilis has declined over the decade 2000-2010.

It remains unclear whether lineages of influenza A(H3N2) virus can persist in the tropics and seed temperate areas. We used viral gene sequence data sampled from Peru to test this source-sink model for a Latin American country. Viruses were obtained during 2010-2012 from influenza surveillance cohorts in Cusco, Tumbes, Puerto Maldonado, and Lima. Specimens positive for influenza A(H3N2) virus were randomly selected and underwent hemagglutinin sequencing and phylogeographic analyses. Analysis of 389 hemagglutinin sequences from Peru and 2,192 global sequences demonstrated interseasonal extinction of Peruvian lineages. Extensive mixing occurred with global clades, but some spatial structure was observed at all sites; this structure was weakest in Lima and Puerto Maldonado, indicating that these locations may experience greater viral traffic. The broad diversity and co-circulation of many simultaneous lineages of H3N2 virus in Peru suggests that this country should not be overlooked as a potential source for novel pandemic strains.

The Belén flora, in north coastal Peru, is the most diverse fruit and seed assemblage known from the Paleogene of South America. Almost no original paleobotanical work has been done on this assemblage since the pioneering treatments published by E.W. Berry, in the 1920’s and the precise age has not been settled. Nevertheless, the flora has been regarded as an important focal point in understanding the vegetational, orogenic and climatic history of northern South America, and in recent literature has been assumed to be early Eocene. In order to tighten the age assignment, which has varied from early Eocene to early Oligocene in the opinions of different authors, we revisited the Belén site, measured the stratigraphic section, and processed the fruit and seed-containing sediment for age-diagnostic microfossils. Although pollen and foraminifera were not recovered, the sediment is rich in diatoms. The diatom assemblage includes Lisitzinia ornata and Rocella vigilans among others, indicating a latest early Oligocene age (~30-28.5 Ma) for these deeper marine sediments that we infer to have been subsequently reworked into the Belén environment . This association leads us to consider the Belén flora, to be late Oligocene in age as is also consistent with its placement in the Mancora Formation. We also reevaluate the botanical identifications, based on the original museum specimens supplemented by more recently collected specimens. The Belén flora provides a window to extinct forests in South America before the rising of the Andes in western Peru.

Peru's importance to the United States in the nineteenth century has been underappreciated because there were few instances of sharp conflict between the two nations. But, beginning with U.S. export of coarse cloth from new cotton mills just after Peruvian independence, continuing during the influence of Peruvian guano on U.S. "scientific agriculture," and then in the period of Peru's extraordinary effort to build trans-Andean railways, Peru exercised important influence on U.S. economy and ...

Radiation Therapy in Peru: Achievements and Challenges
International Nuclear Information System (INIS)
Guerrero, P.; Má, C.; Venegas, D.; Bustamante, R.
2015-01-01
Peru is the fastest growing economy in Latin America (sustained increase in GDP, low inflation and poverty reduction). The health system is fragmented and until 2012, almost half of the population had no health insurance. The current government poses: Improved access to health and education, employment and social security, reducing extreme poverty, within a context of social inclusion. The Plan for Prevention and Control of Cancer (“Plan Esperanza”) was established in 2012 in order to reduce cancer mortality and morbidity, with greater access to oncology services (promotion, prevention, early diagnosis, treatment and palliative care). With an area of 1 285 216 square kilometers and almost 30 million inhabitants, cancer treatment resources are scarce. Regarding Radiation Therapy, until 2007, it existed only in Lima, the capital city (over 9 million inhabitants). Later, another services were established in two more regions. At present, there is 23 radiotherapy machines in whole country. In this regard, Plan Esperanza is working on strengthening Radiation Therapy Services nationwide. Considering the population demand and availability of other cancer services (chemotherapy, oncologic surgery), the regions where need create new radiotherapy services were identified: 3 Hospitals in Lima (in peripheral areas: Cayetano Heredia at the North, Hipólito Unanue at East and Maria Auxiliadora at South). Also, other Regions of the country: Piura, Lambayeque, La Libertad at North; Junín in the Central Highland, Cusco in the Southern Highland, and Loreto in the Northern Forest. Each with 2 linear accelerators, except Loreto, where they will consider two 60 Cobalt bomb instead, due to the geographical conditions. Moreover, one linear accelerator in Arequipa Region will be acquired. In Lima, the Hospitals are projected to become operational in 2016, while in the Regions, the Ministry of Health is providing them technical assistance in needs identification, planning and

Subcutaneous mycoses in Peru: a systematic review and meta-analysis for the burden of disease.
Ramírez Soto, Max Carlos; Malaga, German
2017-10-01
There is a worrying lack of epidemiological data on the geographical distribution and burden of subcutaneous mycoses in Peru, hindering the implementation of surveillance and control programs. This study aimed to estimate the disease burden of subcutaneous mycoses in Peru and identify which fungal species were commonly associated with these mycoses. We performed a meta-analysis after a systematic review of the published literature in PubMed, LILACS, and SciELO to estimate the burden of subcutaneous mycoses in 25 regions in Peru. The disease burden was determined in terms of prevalence (number of cases per 100,000 inhabitants) and the number of reported cases per year per region. A total of 26 studies were eligible for inclusion. Results showed that sporotrichosis was the most common subcutaneous mycosis (99.7%), whereas lobomycosis, chromoblastomycosis, and subcutaneous phaeohyphomycosis were rare. Cases of eumycetoma and subcutaneous zygomycosis were not found. Of the 25 regions, the burden of sporotrichosis was estimated for four regions classified as endemic; in nine regions, only isolated cases were reported. The highest burden of sporotrichosis was in Apurimac (15 cases/100,000 inhabitants; 57 cases/year), followed by Cajamarca (3/100,000 inhabitants; 30/year), Cusco (0.5/100,000 inhabitants; 4/year), and La Libertad (0.2/100,000 inhabitants; 2/year). In two regions, the mycoses predominantly affected children. Sporotrichosis is the most common subcutaneous mycosis in Peru, with a high disease burden in Apurimac. Chromoblastomycosis, lobomycosis, and subcutaneous phaeohyphomycosis are rare mycoses in Peru. © 2017 The International Society of Dermatology.

Full Text Available A new, uniquely colored species of the loricariid catfish genus Otocinclus, O. cocama is described from a tributary to the lower río Ucayali in northern Peru. The new species is distinguished from other Otocinclus species by two putatively autapomorphic features, the distinct color pattern, consisting of vertically elongated blotches spanning from the dorsal midline to the ventral border of flanks, and by a complete lateral line. The phylogenetic relationships of the new species are investigated and it is apparently more closely related to a clade formed by O. huaorani, O. bororo, O. mariae, and O. mura. Comments on the impact of taxonomic revisions for the discovery and description of previously undetected biodiversity are also presented.

Studies were conducted from 1986 through 1993 to further define the geographic distribution and relative importance of different species of Leishmania as a cause of leishmaniasis in Peru. Patients with a clinical diagnosis of cutaneous and/or mucosal or diffuse cutaneous leishmaniasis were enrolled at the Naval Medical Research Institute Detachment (NAMRID) Laboratory in Lima, the Tropical Disease Clinic at San Marcos University Daniel A. Carrión, the Central Military Hospital, and a Ministry of Health hospital in Cusco, Peru. Clinical features, lesion aspirates, and biopsy tissue were obtained from each patient. All specimens were collected and assayed separately, including multiple specimens from some of the same patients for Leishmania parasites by inoculating aliquots of either aspirates or biopsy tissue suspensions onto Senekji's blood agar medium. Stocks of Leishmania isolates were used to prepare promastigotes to produce extracts for identifying the Leishmania species by the cellulose acetate electrophoresis enzyme technique. A total of 351 isolates of Leishmania were obtained from 350 patients who were infected primarily in the low and high jungle of at least 15 different Departments of Peru. Of the 351 isolates, 79% were identified as L. (V.) braziliensis, 7% as L. (V.) guyanensis, 10% as L. (V.) peruviana, 2% as L. (V.) lainsoni, and 1.7% as L. (L.) amazonensis. The clinical form of disease varied depending on the species of Leishmania, with L. (V.) braziliensis being associated most frequently with cutaneous, mucosal ulcers and mixed cutaneous and mucosal disease, and L. (V) peruviana, L. (V.) guyanensis, L. (V.) lainsoni with cutaneous lesions. Leishmania (L.) amazonensis was isolated from six patients, three with cutaneous lesions, one with mucosal lesions, and two with diffuse cutaneous lesions. Among all of the leishmaniasis cases, males were affected more frequently, and cases occurred among patients less than 10 to more than 51 years of age. These

Potential Predictability and Prediction Skill for Southern Peru Summertime Rainfall
WU, S.; Notaro, M.; Vavrus, S. J.; Mortensen, E.; Block, P. J.; Montgomery, R. J.; De Pierola, J. N.; Sanchez, C.
2016-12-01
The central Andes receive over 50% of annual climatological rainfall during the short period of January-March. This summertime rainfall exhibits strong interannual and decadal variability, including severe drought events that incur devastating societal impacts and cause agricultural communities and mining facilities to compete for limited water resources. An improved seasonal prediction skill of summertime rainfall would aid in water resource planning and allocation across the water-limited southern Peru. While various underlying mechanisms have been proposed by past studies for the drivers of interannual variability in summertime rainfall across southern Peru, such as the El Niño-Southern Oscillation (ENSO), Madden Julian Oscillation (MJO), and extratropical forcings, operational forecasts continue to be largely based on rudimentary ENSO-based indices, such as NINO3.4, justifying further exploration of predictive skill. In order to bridge this gap between the understanding of driving mechanisms and the operational forecast, we performed systematic studies on the predictability and prediction skill of southern Peru summertime rainfall by constructing statistical forecast models using best available weather station and reanalysis datasets. At first, by assuming the first two empirical orthogonal functions (EOFs) of summertime rainfall are predictable, the potential predictability skill was evaluated for southern Peru. Then, we constructed a simple regression model, based on the time series of tropical Pacific sea-surface temperatures (SSTs), and a more advanced Linear Inverse Model (LIM), based on the EOFs of tropical ocean SSTs and large-scale atmosphere variables from reanalysis. Our results show that the LIM model consistently outperforms the more rudimentary regression models on the forecast skill of domain averaged precipitation index and individual station indices. The improvement of forecast correlation skill ranges from 10% to over 200% for different

To identify health promoting contents (information that can be transformed into decision-making resources to improve quality of life and the health of individuals or groups) in Facebook postings by the ministries of health in Brazil and Peru. This case study compared the messages published in Facebook by the ministries of health from Brazil and Peru during World AIDS Day. Content analysis was employed to identify health promoting contents in the messages posted between November 2013 and February 2014. A total of 105 messages were published on the topic of interest (37 from Peru and 68 from Brazil). In both cases, most messages focused on individuals, addressing the change or adoption of personal behaviors relating to the prevention and detection of HIV - 34 messages (50.0%) for Brazil and 17 (45.9%) for Peru. Twenty-one (30.9%) messages with a structural emphasis were published by Brazil and 14 (37.8%) by Peru, addressing the context of health care system organization, including HIV/ AIDS health policies, available services, access to HIV testing and initiatives to promote testing. Hybrid messages, including both emphases, were less frequent: 13 (19.1%) for Brazil and six (16.2%) for Peru. Health promoting contents were identified in hybrid messages, which provided resources to expand the understanding of individuals about the susceptibility to AIDS.

Magnetometry and Ground-Penetrating Radar Studies in the Sihuas Valley, Peru
Wisnicki, E.; Papadimitrios, K.; Bank, C.
2013-12-01
The Quillcapampa la Antigua site in Peru's Sihuas Valley is a settlement from Peru's Middle Horizon (600-100 A.D.). Archaeological interest in the area stems from the question of whether ancient civilizations were able to have extensive state control of distant groups, or whether state influence occurred through less direct ties (e.g., marriage, religion, or trade). Our geophysical surveys are preliminary to archaeological digging in the area. Ground-penetrating radar and magnetometry attempt to locate areas of interest for focused archaeological excavation, characterize the design of architectural remains and burial mounds in the area, and allow archaeologists to interpret the amount of influence the Wari civilization had on the local residents.

Safeguard Verification as Cooperative Measure for Non Proliferation Control in Peru
International Nuclear Information System (INIS)
Ramirez, R.
2010-01-01
Peru applies the safeguard measures on its nuclear activities based in the International Atomic Energy Agency (IAEA) Safeguard Agreement and the Additional Protocol which has been fully implemented becoming part of the Integrated Safeguard since 2005. In addition to international safeguard commitments Peru is also committed with the United Nations 1540 Resolution by which national controls has to be established for preventing the proliferation of mass destruction weapons and their vector systems. The safeguards measures have become an important part of the verification activities related to this Resolution by analyzing of materials and equipment to be imported or that may be in transit across the country. These activities are part of those developed jointly with other governmental organizations. (author)

2001-01-01
The paper describes the inventory of radioactive sources in Peru and assesses the control. Three groups of source conditions are established: controlled sources, known sources, and lost and orphan sources. The potential risk, described as not significant, for producing accidents is established and the needed measures are discussed. The paper concludes that, while the control on sealed sources is good, there is still room for improvement. (author)

Camera trap survey of medium and large mammals in a montane rainforest of northern Peru
Directory of Open Access Journals (Sweden)
Carlos F. Jiménez
2011-05-01
Full Text Available Camera traps are a powerful tool for inventorying elusive and rare species and very useful to obtain ecologi- cal data for plans that involve wildlife conservation. In Peru, several surveys have been carried out in lowland Amazonia especially in the southeastern part of the country, but none in montane cloud forests or Yungas. We present the first camera trap studies produced in Peruvian Yungas at the locality of Querocoto village (Chota, Cajamarca, based on 2002 (dry season and 1264 (wet season camera traps-days (CTD. Two localities were surveyed in wet and dry season: The Pagaibamba Protection Forest and the San Lorenzo Forest. The wet season study was carried out in October and November, and the dry season in July to September of 2008. Eight mammalian species were recorded in both seasons. Some 66 (91.7% independent records were obtained in the dry season, but only six (8.3% in the wet one, suggesting a seasonality effect. The Mountain Paca Cunicu- lus taczanowskii was the most commonly photographed species, with 17.0 and 1.6 capture frequencies (dry and wet season respectively, whereas the Long-tailed weasel Mustela frenata (0.5 capture frequency in the dry season was the most rare species. Activity patterns suggest that Mountain Paca C. taczanowskii and the Andean Skunk C. chinga are nocturnal, while Spectacled Bear T. ornatus and Tayra E. barbara are diurnal in the study area. Our records of the Ocelot Leopardus pardalis and the Tayra E. barbara are among the highest altitudinal records known for each species. In addition, the Anta Tapirus pinchaque was also identified by its tracks, representing one of the first record known south of the Huancabamba Depression.

The effects of energy co-governance in Peru
International Nuclear Information System (INIS)
Fontaine, Guillaume
2010-01-01
Soon after the launching of the Camisea Gas Project, in 2000, Peru became a medium-range Latin American gas exporting country. Our central argument is that energy governance in this country has been shifting from a 'hierarchical' to a 'co-governance' mode. Accordingly, interactions among the State, the society and economic actors are now regulated in a horizontal and decentralized way, rather than a vertical and centralized one. This shift contributed to the success of the Camisea gas project and had a positive effect on foreign direct investments inflow in the energy sector (1). In addition, it has helped Peru reach energetic self-sufficiency, while improving its energy balance (2). Meanwhile, energy policy has welcomed a major participation of social actors, contributing to institutionalized arrangements between the State, the companies and indigenous communities and their NGO partners (3). Two theoretical conclusions can be drawn from this study. First, the State's role remains central in energy governance, thus invalidating the 'hollowing of the State' thesis. Second, the co-governance mode helps to overcome the 'resource curse' thesis.

Full Text Available Among odontocetes, members of the family Kogiidae (pygmy and dwarf sperm whales are known as small-sized and in many respects enigmatic relatives of the great sperm whale Physeter macrocephalus. Most of the still scanty fossil record of Kogiidae is represented by isolated skulls and ear bones from Neogene deposits of the Northern Hemisphere, with the significant exception of Scaphokogia, a highly autapomorphic genus from late Miocene deposits of the Pisco Formation exposed along the southern coast of Peru. Here we report on a new fossil kogiid from Aguada de Lomas, a site where the late Miocene beds of the Pisco Formation are exposed. This specimen consists of an almost complete cranium representing a new taxon of Kogiidae: Koristocetus pescei gen. et sp. nov. Koristocetus mainly differs from extant Kogia spp. by displaying a larger temporal fossa and well-individualized dental alveoli on the upper jaws. Coupled with a relatively elongated rostrum, these characters suggest that Koristocetus retained some degree of raptorial feeding abilities, contrasting with the strong suction feeding specialization seen in Recent kogiids. Our phylogenetic analysis recognizes Koristocetus as the earliest branching member of the subfamily Kogiinae. Interestingly, Koristocetus shared the southern coast of present-day Peru with members of the genus Scaphokogia, whose unique convex rostrum and unusual neurocranial morphology seemingly indicate a peculiar foraging specialization that has still to be understood. In conclusion, Koristocetus evokes a long history of high diversity, morphological disparity, and sympatric habits in fossil kogiids, thus suggesting that our comprehension of the evolutionary history of pygmy and dwarf sperm whales is still far from being exhaustive.

This article examines trajectories of nationalism in twentieth-century Argentina, Mexico, and Peru through the analytical lens of schooling. I argue that textbooks reveal state-sponsored conceptions of nationhood. In turn, the outlooks and practices of teachers provide a window for understanding how state ideologies were received, translated, and reworked within society. During the late nineteenth century, textbooks in Mexico, Argentina, and Peru conceived of the nation as a political communi...

Shark fisheries in the Southeast Pacific: A 61-year analysis from Peru
Gonzalez-Pestana, Adriana; Kouri J., Carlos; Velez-Zuazo, Ximena
2016-01-01
Peruvian waters exhibit high conservation value for sharks. This contrasts with a lag in initiatives for their management and a lack of studies about their biology, ecology and fishery. We investigated the dynamics of Peruvian shark fishery and its legal framework identifying information gaps for recommending actions to improve management. Further, we investigated the importance of the Peruvian shark fishery from a regional perspective. From 1950 to 2010, 372,015 tons of sharks were landed in Peru. From 1950 to 1969, we detected a significant increase in landings; but from 2000 to 2011 there was a significant decrease in landings, estimated at 3.5% per year. Six species represented 94% of landings: blue shark ( Prionace glauca), shortfin mako ( Isurus oxyrinchus), smooth hammerhead ( Sphyrna zygaena), common thresher ( Alopias vulpinus), smooth-hound ( Mustelus whitneyi) and angel shark ( Squatina californica). Of these, the angel shark exhibits a strong and significant decrease in landings: 18.9% per year from 2000 to 2010. Peru reports the highest accumulated historical landings in the Pacific Ocean; but its contribution to annual landings has decreased since 1968. Still, Peru is among the top 12 countries exporting shark fins to the Hong Kong market. Although the government collects total weight by species, the number of specimens landed as well as population parameters (e.g. sex, size and weight) are not reported. Further, for some genera, species-level identification is deficient and so overestimates the biomass landed by species and underestimates the species diversity. Recently, regional efforts to regulate shark fishery have been implemented to support the conservation of sharks but in Peru work remains to be done. PMID:27635216

[Anisakidosis a marine parasitic zoonosis: unknown or emerging in Peru?].
Cabrera, Rufino; Del Pilar, María; Altamirano, Trillo
2004-01-01
The purpose of this review is to show the experimental studies carried out on the biological cycle, culture, pathogenicity of the anisakidae nematode larvae and to disseminate the information regarding current epidemy and the probable emergence of anisakidosis in Peru, and in addition, to propose measures of prevention and control, as well as the perspective and need for investigation. The studies of experimental pathogenicity in cats, dos, and hamsters are incomplete. Eight cases of acute human anisakidosis have been reported (5 confirmed and 3 unconfirmed). It is probable that it emerges during the "El Niño" Weather Phenomenon; however, during normal conditions it is probably due to the increase of raw fish consumption and other factors. In the coast of Peru, five and four fishes of direct human consumption are parasited by the Anisakis simplex and Anisakis physeteris larva, respectively, and two fishes are parasited by the Pseudoterranova decipiens. The main host for the Anisakis simplex is the dolphin (Delphinus delphia), but the Contracaecum osculatum is hosted by the sea lion: Otaria byronia and Arctocephalus australis, P. decipiens parasita a O. byronia. Eviscerating the fish would be most adequate prevention method to lessen the risk of human infection. There is evidence that anisakidosis is an underestimated zoonosis in Peru, and that it is probably and emerging disease. Therefore, its presence is to be suspected in patients with the prototype clinical syndrome.

It remains unclear whether lineages of influenza A(H3N2) virus can persist in the tropics and seed temperate areas. We used viral gene sequence data sampled from Peru to test this source–sink model for a Latin American country. Viruses were obtained during 2010–2012 from influenza surveillance cohorts in Cusco, Tumbes, Puerto Maldonado, and Lima. Specimens positive for influenza A(H3N2) virus were randomly selected and underwent hemagglutinin sequencing and phylogeographic analyses. Analysis of 389 hemagglutinin sequences from Peru and 2,192 global sequences demonstrated interseasonal extinction of Peruvian lineages. Extensive mixing occurred with global clades, but some spatial structure was observed at all sites; this structure was weakest in Lima and Puerto Maldonado, indicating that these locations may experience greater viral traffic. The broad diversity and co-circulation of many simultaneous lineages of H3N2 virus in Peru suggests that this country should not be overlooked as a potential source for novel pandemic strains.

The South American gymnophthalmid genus Euspondylus is distributed from Venezuela through Peru, with its highest diversity occurring in Peru. Euspondylus paxcorpus sp. nov. is a new species from Junín, Peru possessing prefrontal scales and represented by 60 specimens. The new species differs from all other species by the combination of four supraoculars with supraocular/supraciliary fusion, 5-7 occipitals, a single palpebral scale, five supralabials and infralabials, quadrangular dorsal scales with low keels arranged in transverse series only, 40-45 in a longitudinal count and 22-28 in a transverse count, 12 rows of ventrals in a transverse count and 23-25 in a longitudinal count, and no sexual dimorphism in coloration. The discovery of E. paxcorpus increases the known number of Euspondylus species to 13. Because the coloration patterns of the specimens were greatly different after preservation in alcohol, caution should be used when identifying Euspondylus species from museum specimens.

Mapping the nutrition transition in Peru: evidence for decentralized nutrition policies.
Chaparro, M Pia; Estrada, Leobardo
2012-09-01
The study objectives were to map the different stages of the nutrition transition for each department within Peru, and to determine the nutrition policy needs for each geographic area based on their current stage in the nutrition transition. Results show that most of the country is suffering from a double-burden of malnutrition, with high rates of stunting among children less than 5 years of age and high rates of overweight and obesity among women of reproductive age. Currently, Peru has only country-wide nutrition policies, administered by the Ministry of Health, that are primarily focused on stunting prevention. This study argues for the need to have decentralized nutrition policies that vary according to what type of malnutrition is being experienced in each geographic area.

Full Text Available This literature review aims to compile publications from 1985 to 2015, such as original articles, short communications and case reports, on the prevalence of liver fluke in cattle, sheep and goats in Peru; as well as to collect scientific articles, conference proceedings and theses carried out at Peruvian universities. A descriptive and transversal bibliometric study was performed, with an internet search strategy based on the combination of keywords and Boolean operators used in databases such as Science Direct, Web of Knowledge, Scopus, and Proquest. Peru has many hyperendemic areas of fascioliosis in cattle and sheep (>50 %, which are within the highest in the world. Goats only have mesoendemic infection rates (10-50 %. The age group of full mouth goats presents the most prevalence within all three species, but the variable of sex shows no significant difference.

Human immunodeficiency virus (HIV)-associated tuberculosis deaths have decreased worldwide over the past decade. We sought to evaluate the effect of HIV status on tuberculosis mortality among patients undergoing treatment for tuberculosis in Lima, Peru, a low HIV prevalence setting. We conducted a prospective cohort study of patients treated for tuberculosis between 2005 and 2008 in two adjacent health regions in Lima, Peru (Lima Ciudad and Lima Este). We constructed a multivariate Cox proportional hazards model to evaluate the effect of HIV status on mortality during tuberculosis treatment. Of 1701 participants treated for tuberculosis, 136 (8.0%) died during tuberculosis treatment. HIV-positive patients constituted 11.0% of the cohort and contributed to 34.6% of all deaths. HIV-positive patients were significantly more likely to die (25.1 vs. 5.9%, P Peru started providing free antiretroviral therapy. As HIV diagnosis and antiretroviral therapy provision are more widely implemented for tuberculosis patients in Peru, future operational research should document the changing profile of HIV-associated tuberculosis mortality.

This study aimed to better understand current clinical practice of rehabilitation professionals in Lima, Peru, and to explore the existence of and potential for interprofessional collaboration. A secondary purpose was to assess rehabilitation professionals' agreement with evidence-based stroke rehabilitation statements and confidence performing stroke rehabilitation tasks prior to and following an interprofessional stroke rehabilitation training. Current clinical practice for rehabilitation professionals in Peru differs from high-income counties like the United States, as physical therapists work with dysphagia and feeding, prosthetist orthotists serve a strictly technical role, and nurses have a limited role in rehabilitation. Additionally, while opportunity for future interprofessional collaboration within stroke rehabilitation exists, it appears to be discouraged by current health system policies. Pre- and post-training surveys were conducted with a convenience sample of 107 rehabilitation professionals in Peru. Survey response options included endorsement of professionals for rehabilitation tasks and a Likert scale of agreement and confidence. Training participants largely agreed with evidence-based stroke rehabilitation statements. Differences in opinion remained regarding the prevalence of dysphagia and optimal frequency of therapy post-stroke. Substantially increased agreement post-training was seen in favour of early initiation of stroke rehabilitation and ankle foot orthosis use. Participants were generally confident performing traditional profession-specific interventions and educating patients and families. Substantial increases were seen in respondents' confidence to safely and independently conduct bed to chair transfers and determine physiological stability. Identification of key differences in rehabilitation professionals' clinical practice in Peru is a first step toward strengthening the development of sustainable rehabilitation systems and

[Human and animal fascioliasis in Peru: impact in the economy of endemic zones].
Espinoza, José R; Terashima, Angélica; Herrera-Velit, Patricia; Marcos, Luis A
2010-01-01
Fasciola hepatica is the causative agent of fasciolosis in Peru; the disease is an important public health problem by the high prevalence of the human infection affecting mainly children and a major veterinary problem by the high rates of infected livestock. The human disease is endemic in the Sierra and the Coast but sporadic in the Amazonia, and reported in 18 Departments, while the animal infection in 21 of 24 Departments of Peru. Transmission occurs in Andean rural populations engaged in agriculture, but recently an increasing number of people became infected in the cities. The epidemiological situation in Peru includes i) Departments with non-autochtonous cases, where infection occurs by consumption of contaminated vegetables brought from endemic areas or infection is acquired by visit to endemic areas; ii) Departments with hypoendemic and mesoendemic villages, where transmission occurs by ingest of contaminated vegetables and prevalence ≤10%; and iii) Departments with hyper-endemic villages with human prevalence >10 %, with an intense transmission by consumption of contaminated vegetables. The disease affects bovine, sheep, goat, swine, equine, South American camelids, rabbits and guinea pigs. The negative impact of fasciolosis in the livestock economy is not lesser than US$ 50 million per year, estimation based on the prevalence and the number of condemned livers in the abattoirs. It is difficult to estimate the economic impact of this infection in the human health due to its status of neglected disease, but fasciolosis is hyper-endemic in the poorest Andean areas of Peru where the situation has to be recognized as a public health emergency.

Cancer is a genetic disease caused by changes in the DNA sequence or expression. Based on the origin of these changes, cancer can be classified as sporadic, and hereditary or familial. Based on the cancer records in Peru, it is expected that 5 to 30% of all patients with cancer, i.e. about 2,000 to 12,000 people, have hereditary cancer, meaning that a similar number of families have a higher risk of developing cancer compared to the general population. Therefore, the purpose of genetic co...

Prevalence of childhood overweight and obesity and associated factors in Peru.
Preston, Emma C; Ariana, Proochista; Penny, Mary E; Frost, Melanie; Plugge, Emma
2015-12-01
To determine the prevalence of and factors associated with childhood overweight and obesity among a cohort of children 7-8 years of age in Peru. This was a cross-sectional secondary analysis of data from the Young Lives longitudinal study of childhood poverty. The sample was a cohort of 1 737 children 7-8 years of age in 2009. Prevalence of overweight and obesity was assessed using body mass index-forage Z-scores. Logistic regression was used to determine associations with a number of individual, household, and community factors. Prevalences of overweight and obesity were 19.2% and 8.6%, respectively. A prevalence of 32.0% and 23.5% overweight and obesity was found among males and females, respectively. High socioeconomic status, living in Lima, having a mother who was overweight or obese, being male, and being an only child or having only one sibling were associated with being overweight and obese at this age. This study shows a high prevalence of childhood and maternal overweight and obesity in Peru. In contrast to findings in many high-income countries, the findings in Peru indicate that children from wealthier households were more likely to be overweight or obese than those from poorer households. In addition, there is something particularly obesogenic about the Lima environment that merits further investigation, and several key issues to consider when targeting future interventions and research.

1981-03-26
The anchovy harvest off the coast of Peru has decreased from a maximum of about 12 million tons in 1970 to about 1 million tons/year between 1977 and 1979. This rise and collapse of the Peruvian anchovy fishery between the 1950s and the 1970s was accompanied by marked changes in the fluxes of a carbon budget for the upwelling ecosystem. These carbon budget changes are discussed in relation to anchovy production. (JMT)

Cystic hydatid disease (CHD) is a common cause of lung and liver disease worldwide. Despite Peru being highly endemic, information about the level of knowledge is scarce and poor. A telephone survey was applied to assess the knowledge in the caregivers of patients treated for CHD at a paediatric hospital at Lima, Peru. Of the 26 contacted families, only 5 (20%) answered correctly all seven questions. A higher education degree was associated with correct answers (P = 0.002). Most respondents (17, 65%) incorrectly identified the etiologic agent and mode of transmission. Lact of knowledge is likely a major contributor to maintain the endemicity of disease in Peru.

A multi-criteria decision analysis approach to assessing malaria risk in northern South America
Directory of Open Access Journals (Sweden)
Temitope O. Alimi
2016-03-01
Full Text Available Abstract Background Malaria control in South America has vastly improved in the past decade, leading to a decrease in the malaria burden. Despite the progress, large parts of the continent continue to be at risk of malaria transmission, especially in northern South America. The objectives of this study were to assess the risk of malaria transmission and vector exposure in northern South America using multi-criteria decision analysis. Methods The risk of malaria transmission and vector exposure in northern South America was assessed using multi-criteria decision analysis, in which expert opinions were taken on the key environmental and population risk factors. Results Results from our risk maps indicated areas of moderate-to-high risk along rivers in the Amazon basin, along the coasts of the Guianas, the Pacific coast of Colombia and northern Colombia, in parts of Peru and Bolivia and within the Brazilian Amazon. When validated with occurrence records for malaria, An. darlingi, An. albimanus and An. nuneztovari s.l., t-test results indicated that risk scores at occurrence locations were significantly higher (p < 0.0001 than a control group of geographically random points. Conclusion In this study, we produced risk maps based on expert opinion on the spatial representation of risk of potential vector exposure and malaria transmission. The findings provide information to the public health decision maker/policy makers to give additional attention to the spatial planning of effective vector control measures. Therefore, as the region tackles the challenge of malaria elimination, prioritizing areas for interventions by using spatially accurate, high-resolution (1 km or less risk maps may guide targeted control and help reduce the disease burden in the region.

We herein describe a new colorful species of Polychrus with a conspicuous sexual dimorphism from the dry forest of the northern portion of Región de La Libertad, Peru. The new species differs from all other Polychrus species, in that this species has very small dorsal scales and thus a higher number of scales around midbody and in the middorsal line from behind the occipital scales to the level of the posterior edge of the thigh. Furthermore, we redescribe Polychrus peruvianus whose original description is short and lacks information on intraspecific variation and sexual dimorphism. Also, we add some information on intraspecific variation and ecology of Polychrus gutturosus. Finally, we synonymize Polychrus spurrelli Boulenger with Polychrus gutturosus.

Cervical cancer is a preventable disease which causes significant morbidity and mortality, particularly in developing countries. Although technology for early detection continues to improve, prevention programs suffer from significant barriers. Community-based participatory research is an approach to research which focuses on collaboration with the community to surmount these barriers. The objective of this study was to evaluate the utility of community-based participatory research techniques in a mother-child screen/treat and vaccinate program for cervical cancer prevention in Manchay, Peru. Human papillomavirus (HPV) self-sampling and cryotherapy were used for the screen/treat intervention, and the Gardasil vaccine was used for the vaccine intervention. Community health workers from Manchay participated in a 3-day educational course, designed by the research team. The community health workers then decided how to implement the interventions in their community. The success of the program was measured by (1) the ability of the community health workers to determine an implementation plan, (2) the successful use of research forms provided, (3) participation and retention rates, and (4) satisfaction of the participants. (1) The community health workers used a door-to-door approach through which participants were successfully registered and both interventions were successfully carried out; (2) registration forms, consent forms, and result forms were used correctly with minimal error; (3) screen/treat intervention: 97% of registered participants gave an HPV sample, 94% of HPV-positive women were treated, and 90% returned for 6-month follow-up; vaccine intervention: 95% of registered girls received the first vaccine, 97% of those received the second vaccine, and 93% the third; (4) 96% of participants in the screen/treat intervention reported high satisfaction. Community-based participatory research techniques successfully helped to implement a screen/treat and vaccinate

Influenza and Other Respiratory Viruses 5(1), 1–5. Background Globally, respiratory infections are the primary cause of illness in developing countries, specifically among children; however, an etiological agent for many of these illnesses is rarely identified. Objectives Our study aimed to estimate the frequency of human bocavirus (HBoV) infection among pediatric populations in Argentina, Nicaragua and Peru. Methods We conducted a cross‐sectional study using stored samples of an influenza‐like illness surveillance program. Irrespective of previous diagnosis, nasopharyngeal or nasal swab specimens were randomly selected and tested using real‐time PCR from three sites during 2007 from patients younger than 6 years old. Results A total of 568 specimens from Argentina (185), Nicaragua (192) and Peru (191) were tested. The prevalence of HBoV was 10·8% (95% CI: 6·3; 15·3) in Argentina, 33·3% in Nicaragua (95% CI: 26·6; 40·1) and 25·1% in Peru (95% CI: 18·9; 31·3). Conclusions These findings demonstrate circulation of HBoV in Argentina, Nicaragua and Peru among children with influenza‐like symptoms enrolled in a sentinel surveillance program. PMID:21138534

This paper reports on strong measures that are being taken to resuscitate Peru's hydrocarbon sector. The first step last August was the cutting of fuel subsidies in half. Then the administration issued tax vouchers to state utilities for the money they still owed national oil company Petroperu. A precursor to what are expected to be widespread changes to the existing petroleum legislation occurred last fall. As part of a package of fiscal reforms, the official base rate that the government paid Occidental Petroleum to produce crude for Petroperu was dropped. A new, free market rate was adopted, which was six times the old base rate

Archaeological excavations at a U-shaped pyramid in the northern Lake Titicaca Basin of Peru have documented a continuous 5-m-deep stratigraphic sequence of metalworking remains. The sequence begins in the first millennium AD and ends in the Spanish Colonial period ca. AD 1600. The earliest dates associated with silver production are 1960 + or - 40 BP (2-sigma cal. 40 BC to AD 120) and 1870 + or - 40 BP (2-sigma cal. AD 60 to 240) representing the oldest known silver smelting in South America. Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) analysis of production debris indicate a complex, multistage, high temperature technology for producing silver throughout the archaeological sequence. These data hold significant theoretical implications including the following: (i) silver production occurred before the development of the first southern Andean state of Tiwanaku, (ii) the location and process of silverworking remained consistent for 1,500 years even though political control of the area cycled between expansionist states and smaller chiefly polities, and (iii) that U-shaped structures were the location of ceremonial, residential, and industrial activities.

The history of 20th century malaria control in Peru.
Griffing, Sean M; Gamboa, Dionicia; Udhayakumar, Venkatachalam
2013-08-30
Malaria has been part of Peruvian life since at least the 1500s. While Peru gave the world quinine, one of the first treatments for malaria, its history is pockmarked with endemic malaria and occasional epidemics. In this review, major increases in Peruvian malaria incidence over the past hundred years are described, as well as the human factors that have facilitated these events, and concerted private and governmental efforts to control malaria. Political support for malaria control has varied and unexpected events like vector and parasite resistance have adversely impacted morbidity and mortality. Though the ready availability of novel insecticides like DDT and efficacious medications reduced malaria to very low levels for a decade after the post eradication era, malaria reemerged as an important modern day challenge to Peruvian public health. Its reemergence sparked collaboration between domestic and international partners towards the elimination of malaria in Peru.

Beijing family strains of Mycobacterium tuberculosis have attracted worldwide attention because of their wide geographical distribution and global emergence. Peru, which has a historical relationship with East Asia, is considered to be a hotspot for Beijing family strains in South America. We aimed to unveil the genetic diversity and transmission characteristics of the Beijing strains in Peru. A total of 200 Beijing family strains were identified from 2140 M. tuberculosis isolates obtained in Lima, Peru, between December 2008 and January 2010. Of them, 198 strains were classified into sublineages, on the basis of 10 sets of single nucleotide polymorphisms (SNPs). They were also subjected to variable number tandem-repeat (VNTR) typing using an international standard set of 15 loci (15-MIRU-VNTR) plus 9 additional loci optimized for Beijing strains. An additional 70 Beijing family strains, isolated between 1999 and 2006 in Lima, were also analyzed in order to make a longitudinal comparison. The Beijing family was the third largest spoligotyping clade in Peru. Its population structure, by SNP typing, was characterized by a high frequency of Sequence Type 10 (ST10), which belongs to a modern subfamily of Beijing strains (178/198, 89.9%). Twelve strains belonged to the ancient subfamily (ST3 [n = 3], ST25 [n = 1], ST19 [n = 8]). Overall, the polymorphic information content for each of the 24 loci values was low. The 24 loci VNTR showed a high clustering rate (80.3%) and a high recent transmission index (RTIn−1 = 0.707). These strongly suggest the active and on-going transmission of Beijing family strains in the survey area. Notably, 1 VNTR genotype was found to account for 43.9% of the strains. Comparisons with data from East Asia suggested the genotype emerged as a uniquely endemic clone in Peru. A longitudinal comparison revealed the genotype was present in Lima by 1999. PMID:23185395

Bioethics has still not acquired an identity of its own in Peru. The Ethics Committee of the Peruvian Medical School and the National AIDS Commission are review committees that deal with ethical problems arising in practice. Doubts regarding quality control of the drugs being tested have been raised in research on human subjects. Questions related to reproduction are very important. There is a high incidence of adolescent pregnancies, and illegal abortions result in many deaths and hospitalizations of women in serious condition. Birth control methods, such as vasectomy, conflict with attitudes about manhood in Peruvian society. Euthanasia is prohibited by the Ethical Code of the Peruvian Medical School, and legislation penalizes assisted suicide. Organ transplantation is hindered by concerns over early declaration of death. Handicapped children are often rejected by society owing to an absurd belief in the possibility that disorders such as Down's syndrome are contagious. The Ministry of Health requires state hospitals to accept AIDS patients, but instances of rejection are still reported.

Is Peru Prepared for Large-Scale Sustainable Rural Electrification?
Directory of Open Access Journals (Sweden)
Sarah Feron
2018-05-01
Full Text Available Peru has historically been among the Latin-American countries with a low rural electrification rate. Aiming to improve this situation, the country conducted several electrification efforts in the last few decades that included off-grid photovoltaic (PV solutions for remote areas (where the grid expansion was unviable. More recently, the government has also sponsored a ‘massive program’ that aims to deploy a minimum of 150,000 off-grid PV solutions in the upcoming years. In this paper, we assess the sustainability of rural electrification programs in Peru, paying special attention to the ongoing “massive program”. Our assessment considers four dimensions of sustainability (institutional, economic, environmental, and socio-cultural and is based on an exhaustive qualitative document analysis complemented by semi-structured expert interviews. We found that the lack of strong formal institutions with a flexible and decentralized structure seriously compromises the sustainability of rural electrification efforts in Peru. Staff rotation and overlapping competences have caused disturbing changes and inhibited following a strategic line, while widespread outsourcing combined with weak controls have often affected the reliability of the deployed systems. Although cross subsidies have made off-grid PV systems affordable for users, systems often fell short of energy demand. Notably, we found that Peruvian officials appear to be unaware of the importance of local participation, and there is a significant mistrust between the government and the rural population (especially in areas where mining is extensive. As a consequence, most of the projects are still designed without the participation and engagement of the communities, which has frequently led to project failures, payment defaults, and inhibited seizing opportunities regarding productive uses of off-grid PV systems. We expect that our findings may help Peruvian institutions to address the most

We present the preliminary results of a provenance study of obsidians samples from Cerrillos (ca. 800-100 b.c.) using Moessbauer Spectroscopy. The Cerrillos archaeological site, located in the Upper Ica Valley, Peru, is the only Paracas ceremonial center excavated so far. The archaeological data collected suggest the existence of a complex social and economic organization on the south coast of Peru. Provenance research of obsidian provides valuable information about the selection of lithic resources by our ancestors and eventually about the existence of communication routes and exchange networks. We characterized 18 obsidian artifacts samples by Moessbauer spectroscopy from Cerrillos. The spectra, recorded at room temperature using different velocities, are mainly composed of broad asymmetric doublets due to the superposition of at least two quadrupole doublets corresponding to Fe 2+ in two different sites (species A and B), one weak Fe 3+ doublet (specie C) and magnetic components associated to the presence of small particles of magnetite. Multivariate statistical analysis of the Moessbauer data (hyperfine parameters) allows to defined two main groups of obsidians, reflecting different geographical origins.

Impacts of Unsustainable Mahogany Logging in Bolivia and Peru
Directory of Open Access Journals (Sweden)
Roberto F. Kometter
2004-06-01
Full Text Available Although bigleaf mahogany [Swietenia macrophylla King (Meliaceae] is the premier timber species of Latin America, its exploitation is unsustainable because of a pattern of local depletion and shifting supply. We surveyed experts on the status of mahogany in Bolivia and Peru, the world's past and present largest exporters. Bolivia no longer has commercially viable mahogany (trees > 60 cm diameter at breast height across 79% of its range. In Peru, mahogany's range has shrunk by 50%, and, within a decade, a further 28% will be logged out. Approximately 15% of the mahogany range in these two countries is protected, but low densities and illegal logging mean that this overestimates the extent of mahogany under protection. The international community can support mahogany conservation by funding park management and by encouraging independent verification of the legality of mahogany in trade. Our findings demonstrate that a systematic expert survey can generate reliable and cost-effective information on the status of widespread species of concern and help to inform appropriate management policy.

We aimed to describe the patterns of nutritional status and sleep duration in children from Ethiopia, India, Peru and Vietnam; to assess the association between short sleep duration and overweight and obesity, and if this was similar among boys and girls in Peru. Analysis of the Young Lives Study, younger cohort, third round. In Ethiopia there were 1,999 observations, 2,011, 2,052 and 2,000 in India, Peru and Vietnam, respectively. Analyses included participants with complete data for sleep duration, BMI, sex and age; missing data: 5.9% (Ethiopia), 4.1% (India), 6.0% (Peru) and 4.5% (Vietnam). Exposure was sleep duration per day: short (overweight and obesity. Multivariable analyses were conducted using a hierarchical approach to assess the effect of variables at different levels. Overweight/obesity prevalence was 0.5%/0.2% (Ethiopia), 1.3%/0.3% (India), 6.1%/2.8% (Vietnam), and 15.8%/5.4% (Peru). Only Peruvian data was considered to explore the association between short sleep duration and overweight and obesity, with 1,929 children, aged 7.9±0.3 years, 50.3% boys. Short and regular sleep duration was 41.6% and 55.6%, respectively. Multivariable models showed that obesity was 64% more prevalent among children with short sleep duration, an estimate that lost significance after controlling for individual- and family-related variables (PR: 1.15; 95%CI: 0.81-1.64). Gender was an effect modifier of the association between short sleep duration and overweight (p = 0.030) but not obesity (p = 0.533): the prevalence ratio was greater than one across all the models for boys, yet it was less than one for girls. Childhood overweight and obesity have different profiles across developing settings. In a sample of children living in resource-limited settings in Peru there is no association between short sleep duration and obesity; the crude association was slightly attenuated by children-related variables but strongly diminished by family-related variables.

2015-11-01
In the present study, we investigated 238 fleas collected from cats and dogs in three regions of Peru (Ancash, Cajamarca, and Lima) for the presence of Bartonella DNA. Bartonella spp. were detected by amplification of the citrate synthase gene (16.4%) and the 16S-23S intergenic spacer region (20.6%). Bartonella rochalimae was the most common species detected followed by Bartonella clarridgeiae and Bartonella henselae. Our results demonstrate that dogs and cats in Peru are infested with fleas harboring zoonotic Bartonella spp. and these infected fleas could pose a disease risk for humans.

METHODS: This was a cross-sectional secondary analysis of data from the Young Lives longitudinal study of childhood poverty. The sample was a cohort of 1 737 children 7-8 years of age in 2009. Prevalence of overweight and obesity was assessed using body mass index-forage Z-scores. Logistic regression was used to determine associations with a number of individual, household, and community factors. RESULTS: Prevalences of overweight and obesity were 19.2% and 8.6%, respectively. A prevalence of 32.0% and 23.5% overweight and obesity was found among males and females, respectively. High socioeconomic status, living in Lima, having a mother who was overweight or obese, being male, and being an only child or having only one sibling were associated with being overweight and obese at this age. CONCLUSIONS: This study shows a high prevalence of childhood and maternal overweight and obesity in Peru. In contrast to findings in many high-income countries, the findings in Peru indicate that children from wealthier households were more likely to be overweight or obese than those from poorer households. In addition, there is something particularly obesogenic about the Lima environment that merits further investigation, and several key issues to consider when targeting future interventions and research.

The 15 August 2007 Peru tsunami runup observations and modeling
Fritz, Hermann M.; Kalligeris, Nikos; Borrero, Jose C.; Broncano, Pablo; Ortega, Erick
2008-05-01
On 15 August 2007 an earthquake with moment magnitude (Mw) of 8.0 centered off the coast of central Peru, generated a tsunami with locally focused runup heights of up to10 m. A reconnaissance team was deployed two weeks after the event and investigated the tsunami effects at 51 sites. Three tsunami fatalities were reported south of the Paracas Peninsula in a sparsely populated desert area where the largest tsunami runup heights were measured. Numerical modeling of the earthquake source and tsunami suggest that a region of high slip near the coastline was primarily responsible for the extreme runup heights. The town of Pisco was spared by the Paracas Peninsula, which blocked tsunami waves from propagating northward from the high slip region. The coast of Peru has experienced numerous deadly and destructive tsunamis throughout history, which highlights the importance of ongoing tsunami awareness and education efforts to ensure successful self-evacuation.

A bi-national appellation of origin: Pisco in Chile and Peru
Directory of Open Access Journals (Sweden)
Pablo Lacoste
2013-12-01
Full Text Available Pisco is a brandy made from selected grapes, restricted as Appellation of Origin (AO in 1931 in Chile by executive order number 181 of May 15, and also legally protected by Peru in 1991 by executive resolution of December 12 and executive order 001-91-ICTI/IND of January 16. This AO has given rise to a commercial controversy between producers of both countries, who claim it as their own. This article proposes a new thesis: The AO of pisco is actually bi-national, belonging to Chile as well as to Peru. The reason is that the producers of the two countries contributed to the origin and consolidation of this product. Pisco would not exist without the participation of both of them. Therefore, the two countries have co-ownership rights since they are co-founders.

Peru is an increasingly popular tourist destination that poses a risk to travelers due to endemic vector-borne diseases (VBDs). The objective of our study was to determine which factors are associated with receiving pre-travel advice (PTA) for VBDs among travelers visiting Cuzco, Peru. A cross-sectional secondary analysis based on data from a survey among travelers departing Cuzco at Alejandro Velazco Astete International Airport during the period January-March 2012 was conducted. From the 1819 travelers included in the original study, 1717 were included in secondary data analysis. Of these participants, 42.2% received PTA and 2.9% were informed about vector-borne diseases, including yellow fever (1.8%), malaria (1.6%) and dengue fever (0.1%). Receiving information on VBDs was associated with visiting areas endemic to yellow fever and dengue fever in Peru. The only disease travelers received specific recommendations for before visiting an endemic area for was yellow fever. Only 1 in 30 tourists received information on VBD prevention; few of those who traveled to an endemic area were warned about specific risks for infectious diseases prior to their trip. These important findings show that most tourists who travel to Peru do not receive PTA for the prevention of infectious and VBD, which can affect not only the travelers but their countries of origin as well.

Rubella during pregnancy can cause serious fetal abnormalities and death. Peru has had integrated measles/rubella surveillance since 2000 but did not implement congenital rubella syndrome (CRS) surveillance until 2004, in accordance with the Pan American Health Organization recommendations for rubella elimination. The article describes the experience from the CRS sentinel surveillance system in Peru. Peru has maintained a national sentinel surveillance system for reporting confirmed and suspected CRS cases since 2004. A surveillance protocol was implemented with standardized case definitions and instruments in the selected sentinel sites. Each sentinel site completes their case investigations and report forms and sends the reports to the Health Region Epidemiology Department, which forwards the data to the national Epidemiology Department. CRS surveillance data were analyzed for the period 2004-2007. During the period 2004-2007, 16 health facilities, which are located in 9 of the 33 health regions, representing the 3 main geographical areas (coast, mountain, and jungle), were included as sentinel sites for the CRS surveillance. A total of 2061 suspected CRS cases were reported to the system. Of these, 11 were classified as CRS and 23 as congenital rubella infection. Factors significantly associated with rubella vertical transmission were: (1) in the mother, maternal history of rash during pregnancy (odds ratio [OR], 12.0; 95% confidence interval [CI], 3.8-37.8); (2) and in the infant, pigmentary retinopathy (OR, 18.4; 95% CI, 3.2-104.6), purpura (OR, 14.7; 95% CI, 2.8-78.3), and developmental delay (OR, 4.4; 95% CI, 1.75-11.1). The surveillance system has been able to identify rubella vertical transmission, reinforcing the evidence that rubella was a public health problem in Peru. This system may serve as a platform to implement surveillance for other congenital infections in Peru.

Breast cancer incidence and mortality rates continue to rise in Peru, with related deaths projected to increase from 1208 in 2012, to 2054 in 2030. Despite improvements in national cancer control plans, various barriers to positive breast cancer outcomes remain. Multiorganisational stakeholder collaboration is needed for the development of functional, sustainable early diagnosis, treatment and supportive care programmes with the potential to achieve measurable outcomes. In 2011, PATH, the Peruvian Ministry of Health, the National Cancer Institute in Lima, and the Regional Cancer Institute in Trujillo collaborated to establish the Community-based Program for Breast Health, the aim of which was to improve breast health-care delivery in Peru. A four-step, resource-stratified implementation strategy was used to establish an effective community-based triage programme and a practical early diagnosis scheme within existing multilevel health-care infrastructure. The phased implementation model was initially developed by the Breast Cancer Initiative 2·5: a group of health and non-governmental organisations who collaborate to improve breast cancer outcomes. To date, the Community-based Program for Breast Health has successfully implemented steps 1, 2, and 3 of the Breast Cancer Initiative 2·5 model in Peru, with reports of increased awareness of breast cancer among women, improved capacity for early diagnosis among health workers, and the creation of stronger and more functional linkages between the primary levels (ie, local or community) and higher levels (ie, district, region, and national) of health care. The Community-based Program for Breast Health is a successful example of stakeholder and collaborator involvement-both internal and external to Peru-in the design and implementation of resource-appropriate interventions to increase breast health-care capacity in a middle-income Latin American country.

To determine the proportion of postpartum women aged 15-49 in Peru who are susceptible to rubella, in order to help address strategies to eliminate rubella and to prevent congenital rubella syndrome (CRS) in the country. A cross-sectional survey was conducted during March and April 2003 in six main regional hospitals, in the three geographic regions (coast, mountain, and jungle) of Peru. For the postpartum women who provided written informed consent, a questionnaire was administered and a blood specimen was collected. Sera were tested for rubella immunoglobulin G (IgG) antibody, using a commercial enzyme-linked immunosorbent serologic assay (ELISA) kit. Univariate, bivariate, and multivariate analyses were carried out to assess risk factors for susceptibility. In total, 1 236 postpartum women were enrolled. The overall proportion of IgG-antibody negative women was 12.8% (95% confidence interval (CI): 10.9%-14.6%). Bivariate analysis found the following variables associated with susceptibility: living in the jungle region (odds ratio (OR) = 1.65; 95% CI: 1.13-2.42); age jungle region (OR = 1.67; 95% CI: 1.13-2.46); age Peru among the countries facing a moderate level of risk for the occurrence of CRS cases. The findings suggest the need to also provide the rubella vaccine to other population groups, especially women of childbearing age.

Peru has made great improvements in reducing stunting and child mortality in the past decade, and has reached the Millennium Development Goals 1 and 4. The remaining challenges or missed opportunities for child survival needs to be identified and quantified, in order to guide the next steps to further improve child survival in Peru. We used the Lives Saved Tool (LiST) to project the mortality impact of proven interventions reaching every women and child in need, and the mortality impact of eliminating inequalities in coverage distribution between wealth quintiles and urban-rural residence. Our analyses quantified the remaining missed opportunities in Peru, where prioritizing scale-up of facility-based case management for all small and sick babies will be most effective in mortality reduction, compared to other evidenced-based interventions that prevent maternal and child deaths. Eliminating coverage disparities between the poorest quintiles and the richest will reduce under-five and neonatal mortality by 22.0 and 40.6 %, while eliminating coverage disparities between those living in rural and urban areas will reduce under-five and neonatal mortality by 29.3 and 45.2 %. This projected neonatal mortality reduction achieved by eliminating coverage disparities is almost comparable to that already achieved by Peru over the past decade. Although Peru has made great strides in improving child survival, further improvement in child health, especially in newborn health can be achieved if there is universal and equitable coverage of proven, quality health facility-based interventions. The magnitude of reduction in mortality will be similar to what has been achieved in the past decade. Strengthening health system to identify, understand, and direct resources to the poor and rural areas will ensure that Peru achieve the Sustainable Development Goals by 2030.

Rural Community Disaster Preparedness and Risk Perception in Trujillo, Peru.
Stewart, Matthew; Grahmann, Bridget; Fillmore, Ariel; Benson, L Scott
2017-08-01
Introduction Disasters will continue to occur throughout the world and it is the responsibility of the government, health care systems, and communities to adequately prepare for potential catastrophic scenarios. Unfortunately, low-and-middle-income countries (LMICs) are especially vulnerable following a disaster. By understanding disaster preparedness and risk perception, interventions can be developed to improve community preparedness and avoid unnecessary mortality and morbidity following a natural disaster. Problem The purpose of this study was to assess disaster preparedness and risk perception in communities surrounding Trujillo, Peru. After designing a novel disaster preparedness and risk perception survey based on guidelines from the International Federation of Red Cross and Red Crescent Societies (IFRC; Geneva, Switzerland), investigators performed a cross-sectional survey of potentially vulnerable communities surrounding Trujillo, Peru. Data were entered and analyzed utilizing the Research Electronic Data Capture (REDCap; Harvard Catalyst; Boston, Massachusetts USA) database. A total of 230 study participants were surveyed, composed of 37% males, 63% females, with ages ranging from 18-85 years old. Those surveyed who had previously experienced a disaster (41%) had a higher perception of future disaster occurrence and potential disaster impact on their community. Overall, the study participants consistently perceived that earthquakes and infection had the highest potential impact of all disasters. Twenty-six percent of participants had an emergency supply of food, 24% had an emergency water plan, 24% had a first aid kit at home, and only 20% of the study participants had an established family evacuation plan. Natural and man-made disasters will remain a threat to the safety and health of communities in all parts of the world, especially within vulnerable communities in LMICs; however, little research has been done to identify disaster perception

Climatic Cycles and Gradients of the El Niño Core Region in North Peru
Directory of Open Access Journals (Sweden)
Rütger Rollenbeck
2015-01-01
Full Text Available Climatic processes in northern Peru are evaluated on surface observation independent of modelling studies. The region is characterized by regular oscillations, but episodic El Niño-events introduce strong disturbances. Conceptual models based on observations, remote sensing data, and output of regional climate models are compared with data from a new station network. The results show regular oscillations of all climate variables on the annual and daily time scale. The daily cycle is probably associated with thermotidal forcings, causing gravity waves to emanate from the Andes Cordillera. Main factors are the interaction of large scale pressure systems like the Southeast Pacific High and the intertropical convergence zone (ITCZ. Also, there are regional factors: an extended sea-breeze system, the barrier-effect of the Andes, additional energy input by elevated radiation absorption at the mountain slopes, local wind systems, and the variations of the sea surface temperature. At the coast, a low-level jet works as a thermodynamic energy sink, suppressing deep convection and supporting the aridity. Those patterns are found in most of the station data and the processes of this climate can generally be confirmed. The overturning of this stable system with the onset of El Niño-conditions is possibly caused by disruptions of the regional circulation.

Young adults 18 to 25 years old show the highest prevalence of marijuana use in Latin America. This study analyzes the changes in prevalence of marijuana use among university students in the Andean Community (Bolivia, Colombia, Ecuador, and Peru) from two studies carried out in 2009 and in 2012. Data were collected through representative two-stage samples of universities and students in the Andean Community. An online survey was administered using a standardized questionnaire. Prevalence was calculated for lifetime, past year, and past month. Marijuana was the most widely used illicit substance consumed among university students, in 2009 and in 2012. Past month prevalence among university students in 2009 in Colombia was 5.27%, in Peru 1.00%, in Ecuador 1.68%, and in Bolivia 0.76%. Past month prevalence in 2012 in Colombia was 7.14%, in Ecuador 3.67%, in Peru 1.62%, and in Bolivia 1.45% in 2012. Among university students in the Andean Community, past month prevalence increased among both males and females between 2009 and 2012 in most countries. Marijuana continues to be the most commonly used illicit drug in Latin American countries. Increases in prevalence among young adults could have important implications for national drug policy.

Statistical panorama of female physics graduate students for 2000-2010 in Peru
Cerón Loayza, María Luisa; Bravo Cabrejos, Jorge Aurelio
2013-03-01
We report the results of a statistical study on the number of women entering the undergraduate and master's programs of physics at Universidad Nacional Mayor de San Marcos in Peru. From 2006 through 2010, 13 female students entered the master's degree program but no females graduated with the degree. Considering that Peru is a developing country, a career in physics is not considered an attractive professional choice even for male students because it is thought that there are no work centers to practice this profession. We recommend that the causes preventing female physics students from completing their studies and research work be analyzed, and that strategies be planned to help women complete their academic work. We are considering getting help from the Peruvian Physics Society (SOPERFI) in order to draw more attention for our plan.

Abandonment of treatment is a major cause of treatment failure and poor survival in children with cancer in low- and middle-income countries. The incidence of treatment abandonment in Peru has not been reported. The aim of this study was to examine the prevalence of and factors associated with treatment abandonment by pediatric patients with solid tumors in Peru. We retrospectively reviewed the sociodemographic and clinical data of children referred between January 2012 and December 2014 to the two main tertiary centers for childhood cancer in Peru. The definition of treatment abandonment followed the International Society of Paediatric Oncology, Paediatric Oncology in Developing Countries, Abandonment of Treatment recommendation. Data from 1135 children diagnosed with malignant solid tumors were analyzed, of which 209 (18.4%) abandoned treatment. Bivariate logistic regression analysis showed significantly higher abandonment rates in children living outside the capital city, Lima (forest; odds ratio [OR] 3.25; P < 0.001), those living in a rural setting (OR 3.44; P < 0.001), and those whose parent(s) lacked formal employment (OR 4.39; P = 0.001). According to cancer diagnosis, children with retinoblastoma were more likely to abandon treatment compared to children with other solid tumors (OR 1.79; P = 0.02). In multivariate regression analyses, rural origin (OR 2.02; P = 0.001) and lack of formal parental employment (OR 2.88; P = 0.001) were independently predictive of abandonment. Treatment abandonment prevalence of solid tumors in Peru is high and closely related to sociodemographical factors. Treatment outcomes could be substantially improved by strategies that help prevent abandonment of therapy based on these results. © 2018 Wiley Periodicals, Inc.

Full Text Available Whale watching is the human activity of encountering cetaceans in their natural habitat for recreational and scientific purposes. Despite the high diversity of cetaceans in Peruvian waters, this activity has yet to be developed. Herein we present data regarding the distribution of humpback whales (Megaptera novaeangliae off northern Peru, evaluating the possibility of extending whale watching activities in this area. Data were obtained from surveys conducted from an ecotourism boat. Humpbacks were distributed in shallow waters, usually in pairs or trios throughout the study period between late July and late September. The presence of whales off northern Peru is due to winter migration for breeding and calving purposes. A high probability of encountering humpbacks within the study area could encourage the development of a whale watching industry. As this stage in the life cycle of this species is very delicate, we suggest the adoption of the precautionary principie in the management of the activity in order to minimize the risk of negative impacts on humpback populations. Whale watching in northern Peru is feasible and could be considered an alternative to fishing.La observación de ballenas es la actividad humana de observar estos cetáceos en su habitat natural con fines recreacionales y científicos.

'You should build yourself up as a whole product': Transgender female identity in Lima, Peru.
Pollock, Lealah; Silva-Santisteban, Alfonso; Sevelius, Jae; Salazar, Ximena
2016-01-01
Transgender women in Lima, Peru have, until recently, been grouped together with gay and bisexual men in the category MSM, or men who have sex with men, with little consideration of their unique situation and needs. Transgender women, self-identified in Peru as travesti, are a socially vulnerable population with many unmet health needs, including an HIV prevalence of 30%. Understanding specific transgender identities and their contexts will contribute to the improvement and development of HIV prevention programs. Through qualitative open-ended interviews with trans-identified women in Lima, Peru, this study found that the non-normative travesti identity is constructed within a conservative homophobic and heteronormative social context. Participants strive towards appearances and relationships perceived as feminine, seeking out silicone injections and abusive men as social markers of this femininity. Sex work is the primary economic activity available and travestis are often alienated from their families and communities. Work is needed to increase self-esteem and decrease violence, stigma, and discrimination. There is a need for multilevel HIV prevention campaigns prioritising travesti in Lima, utilising a human rights framework.

CIRPLAST: Cleft Lip and Palate Missions in Peru.
Navarro, Carlos E
2015-06-01
The author presents a 20-year experience leading cleft lip and palate surgical volunteer missions in Peru for CIRPLAST, a nonprofit volunteer plastic surgery goodwill program that has provided free surgery for patients with cleft lip and palate deformities in remote areas of Peru. Surgical procedures were performed by the author, together with a group of experienced plastic surgeons, under the auspices of the Peruvian Plastic Surgery Society, and local health authorities. CIRPLAST missions are scheduled annually in different locations around Peru. Selected patients for surgery after adequate screening are photographed, and their cleft deformity is recorded. Scheduled patients or their parents, when they are minors, sign an informed consent form. Patients operated on in any given day are examined and photographed 1 day after surgery, before discharge. Between 30 and 35 patients are operated on at each mission site. About 2 weeks after the mission, patients are checked and photographed, and the outcome of surgery is recorded. Complications that may occur are recorded and treated by the CIRPLAST team as soon as possible. Almost all operations are performed under general endotracheal anesthesia coupled by local anesthesia containing a vasoconstrictor, to reduce bleeding and facilitate tissue dissection. All wounds of the lip and palate are closed with absorbable sutures, to avoid the need for suture removal. After cleft lip surgery, patients go to the recovery room for monitoring by nurses until they recover completely. A total of 6108 cleft lip and palate repairs, primary and secondary, were performed by CIRPLAST in 141 missions, between May 12, 1994, and October 15, 2014. The medical records of the 5162 patients (84.5%) who returned for follow-up (ranging from 12 days to 9 years) were reviewed retrospectively. Between 45% and 70% of the patients operated on a mission have returned for early follow-up and some the following year. There were 3176 males (51.9%) and 2932

[The concept of man and alcoholism in ancient Peru].
Mariátegui, J
1985-12-01
In the ancient Peru, particularly in the Inca Empire, the review of alcohol use and abuse must be made according to the ethnohistorical and cultural context with special emphasis on ideological and customary aspects. The outstanding research sources of alcohol consume types and characteristics are: a) The examination of chronicles of the Spanish Conquest and related papers on a textual criticism; b) The study of language from its semantic scope; and c) The archaeological and ethnological testimony. The only alcoholic beverage existing in the Inca's times was "chicha", mainly that of corn fermentation which was used under the ceremonial, ritual and convivial modalities. The pathological drinking types are clearly defined in the lexicon of the Pre-Columbian Peru prevailing languages, mainly Quechua. The social control of drinking overindulgence was evident and the repressive and punitive measures were similar to those of the great ancient civilizations. The image conveyed by most of the chroniclers as to alcohol excessive drinking among Inca people belongs to the trauma of Conquest which suppressed the psychopolitical and sociocultural control that supported their universe of values generating all sort of misbehaviors and selfdestructive types of toxic consume.

METHODS AND FINDINGS: Analysis of the Young Lives Study, younger cohort, third round. In Ethiopia there were 1,999 observations, 2,011, 2,052 and 2,000 in India, Peru and Vietnam, respectively. Analyses included participants with complete data for sleep duration, BMI, sex and age; missing data: 5.9% (Ethiopia, 4.1% (India, 6.0% (Peru and 4.5% (Vietnam. Exposure was sleep duration per day: short (<10 hours versus regular (10-11 hours. Outcome was overweight and obesity. Multivariable analyses were conducted using a hierarchical approach to assess the effect of variables at different levels. Overweight/obesity prevalence was 0.5%/0.2% (Ethiopia, 1.3%/0.3% (India, 6.1%/2.8% (Vietnam, and 15.8%/5.4% (Peru. Only Peruvian data was considered to explore the association between short sleep duration and overweight and obesity, with 1,929 children, aged 7.9±0.3 years, 50.3% boys. Short and regular sleep duration was 41.6% and 55.6%, respectively. Multivariable models showed that obesity was 64% more prevalent among children with short sleep duration, an estimate that lost significance after controlling for individual- and family-related variables (PR: 1.15; 95%CI: 0.81-1.64. Gender was an effect modifier of the association between short sleep duration and overweight (p = 0.030 but not obesity (p = 0.533: the prevalence ratio was greater than one across all the models for boys, yet it was less than one for girls. CONCLUSIONS: Childhood overweight and obesity have different profiles across developing settings. In a sample of children living in resource-limited settings in Peru there is no association between short sleep duration and obesity; the crude association was slightly

[Experiences in the prevention and control of Carrión's disease in Peru].
Maguiña Vargas, Ciro; Pachas, Paul
2014-04-01
Carrion's disease, the iconic disease in Peruvian medicine has been found in the mountains of Ecuador, Colombia and the Andean valleys of Peru. In the 1990s, the phenomenon of El Niño was associated with significantly increased risk of disease in Ancash, Cajamarca and Cusco. In Cusco in 1998 there was an acute phase epidemic in various Andean provinces and the jungle area. Between 2001 and 2005 the disease has spread or reactivated in different regions such as Ancash, Cajamarca, Amazonas, Piura, Cusco, La Libertad, Puno, and Ayacucho. In 2004 a major outbreak of the disease in all of Peru was presented, reporting more than 11 164 cases, and therefore diverse strategies based vector susceptibility studies was applied, lowering significantly the number of cases.

2003-05-01
The Cosmos Coronagraphic Observatory was completely destroyed by terrorists in 1988. In 1995, in coordination with the Minister of Education of Peru, a project to construct a new Educational Astronomical Observatory has been executed. The main purpose of the observatory is to promote an interest in basic space sciences in young students from school to university levels, through basic astronomical studies and observations. The planned observatory will be able to lodge 25 visitors; furthermore an auditorium, a library and a computer room will be constructed to improve the interest of people in astronomy. Two 15-cm refractor telescopes, equipped with a CCD camera and a photometer, will be available for observations. Also a 6-m dome will house a 60-cm class reflector telescope, which will be donated soon, thanks to a fund collected and organized by the Nishi-Harima Astronomical Observatory in Japan. In addition a new modern planetarium donated by the Government of Japan will be installed in Lima, the capital of Peru. These installations will be widely open to serve the requirements of people interested in science.

Assessment of patient safety culture in private and public hospitals in Peru.
Arrieta, Alejandro; Suárez, Gabriela; Hakim, Galed
2018-04-01
To assess the patient safety culture in Peruvian hospitals from the perspective of healthcare professionals, and to test for differences between the private and public healthcare sectors. Patient safety is defined as the avoidance and prevention of patient injuries or adverse events resulting from the processes of healthcare delivery. A non-random cross-sectional study conducted online. An online survey was administered from July to August 2016, in Peru. This study reports results from Lima and Callao, which are the capital and the port region of Peru. A total of 1679 healthcare professionals completed the survey. Participants were physicians, medical residents and nurses working in healthcare facilities from the private sector and public sector. Assessment of the degree of patient safety and 12 dimensions of patient safety culture in hospital units as perceived by healthcare professionals. Only 18% of healthcare professionals assess the degree of patient safety in their unit of work as excellent or very good. Significant differences are observed between the patient safety grades in the private sector (37%) compared to the public sub-sectors (13-15%). Moreover, in all patient safety culture dimensions, healthcare professionals from the private sector give more favorable responses for patient safety, than those from the public sub-systems. The most significant difference in support comes from patient safety administrators through communication and information about errors. Overall, the degree of patient safety in Peru is low, with significant gaps that exist between the private and the public sectors.

Glacial evolution of the Ampato Volcanic Complex (Peru)
Alcalá, J.; Palacios, D.; Zamorano, J. J.; Vázquez, L.
2009-04-01
Ice masses on the Western range of the Central Andes are a main source of water resources and act as a geoindicator of variations in the climate of the tropics (Mark, 2008). The study of their evolution is of particular interest since they are situated in the transition zone between the tropical and mid-latitude circulation areas of the atmosphere (Zech et al., 2007). The function of this transition area is currently under debate, and understanding it is essential for the development of global climate models (Kull et al, 2008; Mark, 2008). However our understanding of the evolution of glaciers and their paleoclimatic factors for this sector of the Central Andes is still at a very basic level. This paper presents initial results of a study on the glacial evolution of the Ampato volcanic complex (15°24´- 15° 51´ S, 71° 51´ - 73° W; 6288 m a.s.l.) located in the Western Range of the Central Andes in Southern Peru, 70 km NW of the city of Arequipa. The main objectives are to identify the number of glacial phases the complex has undergone using geomorphological criteria to define a time frame for each phase, based on cosmogenic 36Cl dating of a sequence of moraine deposits; and to estimate the glacier Equilibrium Line Altitude (ELA) of each phase. The Ampato volcanic complex is formed by 3 great andesitic stratovolcanoes, the Nevados HualcaHualca-Sabancaya-Ampato, which started forming between the late Miocene and early Quaternary (Bulmer et al., 1999), aligned N-S and with summits covered with glaciers. The Sabancaya volcano is fully active, with its latest eruption occurring in 2001. Glacial landforms were identified and mapped using photointerpretation of vertical aerial photographs from 1955 (1:35,000 scale, National Geographic Institute of Peru), oblique photographs from 1943 (Aerophotographical Service of Peru), and a geo-referenced high-resolution Mrsid satellite image from 2000 (NASA). This cartography was corrected and improved through fieldwork. It was

Cost-effectiveness of norovirus vaccination in children in Peru.
Mirelman, Andrew J; Ballard, Sarah Blythe; Saito, Mayuko; Kosek, Margaret N; Gilman, Robert H
2015-06-17
With candidate norovirus (NV) vaccines in a rapid phase of development, assessment of the potential economic value of vaccine implementation will be necessary to aid health officials in vaccine implementation decisions. To date, no evaluations have been performed to evaluate the benefit of adopting NV vaccines for use in the childhood immunization programs of low- and middle-income countries. We used a Markov decision model to evaluate the cost-effectiveness of adding a two-dose NV vaccine to Peru's routine childhood immunization schedule using two recent estimates of NV incidence, one for a peri-urban region and one for a jungle region of the country. Using the peri-urban NV incidence estimate, the annual cost of vaccination would be $13.0 million, offset by $2.6 million in treatment savings. Overall, this would result in 473 total DALYs averted; 526,245 diarrhea cases averted;153,735 outpatient visits averted; and 414 hospitalizations averted between birth and the fifth year of life. The incremental cost-effectiveness ratio would be $21,415 per DALY averted; $19.86 per diarrhea case; $68.23 per outpatient visit; and $26,298 per hospitalization. Using the higher jungle NV incidence rates provided a lower cost per DALY of $10,135. The incremental cost per DALY with per-urban NV incidence is greater than three times the 2012 GDP per capita of Peru but the estimate drops below this threshold using the incidence from the jungle setting. In addition to the impact of incidence, sensitivity analysis showed that vaccine price and efficacy play a strong role in determining the level of cost-effectiveness. The introduction of a NV vaccine would prevent many healthcare outcomes in the Peru and potentially be cost-effective in scenarios with high NV incidence. The vaccine cost-effectiveness model could also be applied to the evaluation of NV vaccine cost-effectiveness in other countries. In resource-poor settings, where NV incidence rates are expected to be higher. Published

[eHealth in Peru: implementation of policies to strengthen health information systems].
Curioso, Walter H
2014-01-01
Health information systems play a key role in enabling high quality, complete health information to be available in a timely fashion for operational and strategic decision-making that makes it possible to save lives and improve the health and quality of life of the population. In many countries, health information systems are weak, incomplete, and fragmented. However, there is broad consensus in the literature of the need to strengthen health information systems in countries around the world. The objective of this paper is to present the essential components of the conceptual framework to strengthen health information systems in Peru. It describes the principal actions and strategies of the Ministry of Health of Peru during the process of strengthening health information systems. These systems make it possible to orient policies for appropriate decision-making in public health.

Protected areas (PAs) are a conservation mainstay and arguably the most effective conservation strategy for species protection. As a 'megadiverse' country, Peru is a priority for conservation actions. Peruvian legislation allows for the creation of state PAs and private/communal PAs. Using publicly available species distribution and protected area data sets we evaluated the coverage of Threatened terrestrial vertebrate species distributions and ecoregions provided by both kinds of PA in Peru. Peru's state PA system covers 217,879 km 2 and private/communal PAs cover 16,588 km 2 . Of the 462 species of Threatened and Data Deficient species we evaluated, 75% had distributions that overlapped with at least one PA but only 53% had ≥10% of their distributions within PAs, with inclusion much reduced at higher coverage targets. Of the species we evaluated, 118 species are only found in national PAs and 29 species only found in private/communal PAs. Of the 17 terrestrial ecoregions found in Peru all are represented in PAs; the national PA system included coverage of 16 and private/communal PAs protect 13. One ecoregion is only protected in private/communal PAs, whereas four are only covered in national PAs. Our results show the important role private/communal PAs can play in the protection of ecological diversity. Copyright © 2017 Elsevier Ltd. All rights reserved.

Weekly multimicronutrient supplementation was initiated as an appropriate intervention to protect poor urban populations from anemia. To identify the lessons learned from the Integrated Food Security Program (Programa Integrado de Seguridad Alimentaria [PISA]) weekly multimicronutrient supplementation program implemented in poor urban populations of Chiclayo, Peru. Data were collected from a 12-week program in which multimicronutrient supplements were provided weekly to women and adolescent girls 12 through 44 years of age and children under 5 years of age. A baseline survey was first conducted. Within the weekly multimicronutrient supplementation program, information was collected on supplement distribution, compliance, biological effectiveness, and cost. Supplementation, fortification, and dietary strategies can be integrated synergistically within a micronutrient intervention program. To ensure high cost-effectiveness of a weekly multimicronutrient supplementation program, the following conditions need to be met: the program should be implemented twice a year for 4 months; the program should be simultaneously implemented at the household (micro), community (meso), and national (macro) levels; there should be governmental participation from health and other sectors; and there should be community and private sector participation. Weekly multimicronutrient supplementation programs are cost effective options in urban areas with populations at low risk of energy deficiency and high risk of micronutrient deficiencies.

[History of training and certification programs of medical specialists in Peru].
Burstein Alva, Zuño
2014-01-01
In this paper, historical reference is made about legal provisions for recognition of the training and certification of medical specialists in Peru through university programs provided since 1928 and culminating in 1973 with the legal authorization by the relevant state authority to implement the Second Specialization Program in Human Medicine and to grant the Certification of Specialist in the Name of the Nation upon completion of a university residency program and specialized training by the regular modality, and the recognition by the university with the non-regular modality. In Peru it has been established to the present that the Professional Certifications of Specialists in Human Medicine in the Name of the Nation, both in regular modality as well as in non-regular modality, can only be granted by public or private universities authorized for this mission and, besides, no other public or private institution can claim this role that corresponds exclusively for the Peruvian University.

Highly refined surveillance data on the 2009 A/H1N1 influenza pandemic are crucial to quantify the spatial and temporal characteristics of the pandemic. There is little information about the spatial-temporal dynamics of pandemic influenza in South America. Here we provide a quantitative description of the age-specific morbidity pandemic patterns across administrative areas of Peru. We used daily cases of influenza-like-illness, tests for A/H1N1 influenza virus infections, and laboratory-confirmed A/H1N1 influenza cases reported to the epidemiological surveillance system of Peru's Ministry of Health from May 1 to December 31, 2009. We analyzed the geographic spread of the pandemic waves and their association with the winter school vacation period, demographic factors, and absolute humidity. We also estimated the reproduction number and quantified the association between the winter school vacation period and the age distribution of cases. The national pandemic curve revealed a bimodal winter pandemic wave, with the first peak limited to school age children in the Lima metropolitan area, and the second peak more geographically widespread. The reproduction number was estimated at 1.6-2.2 for the Lima metropolitan area and 1.3-1.5 in the rest of Peru. We found a significant association between the timing of the school vacation period and changes in the age distribution of cases, while earlier pandemic onset was correlated with large population size. By contrast there was no association between pandemic dynamics and absolute humidity. Our results indicate substantial spatial variation in pandemic patterns across Peru, with two pandemic waves of varying timing and impact by age and region. Moreover, the Peru data suggest a hierarchical transmission pattern of pandemic influenza A/H1N1 driven by large population centers. The higher reproduction number of the first pandemic wave could be explained by high contact rates among school-age children, the age group most affected

Previous studies of inequality in health and mortality have largely focused on income-based inequality. Maternal education plays an important role in determining access to water and sanitation, and inequalities in child mortality arising due to differential access, especially in low- and middle-income countries such as Peru. This article aims to explain education-related inequalities in child mortality in Peru using a regression-based decomposition of the concentration index of child mortalit...

Modeling an economic evaluation of a salt fluoridation program in Peru.
Mariño, Rodrigo J; Fajardo, Jorge; Arana, Ana; Garcia, Carlos; Pachas, Flor
2011-01-01
This article models the cost-effectiveness, from a societal viewpoint, of a dental caries prevention program using salt fluoridation for children 12 years of age, compared with non-intervention (or status quo) in Arequipa, Peru. Standard cost-effectiveness analysis methods were used. The costs associated with implementing and operating the salt-fluoridation program were identified and measured using 2009 prices. Health outcomes were measured as dental caries averted over a 6-year period. Clinical effectiveness data was taken from published data. Costs were measured as direct treatment costs, programs costs and costs of productivity losses as a result of dental treatments. The incremental cost-effectiveness ratio was calculated. A hypothetical population of 25,000 12-year-olds living in Arequipa, Peru was used in this analysis. Two-way sensitivity analyses were conducted over a range of values for key parameters. Our primary analysis estimated that if a dental caries prevention program using salt-fluoridation was available for 25,000 6-year-old children for 6 years, the net saving from a societal perspective would total S/. 11.95 [1 US$ = S/. (2009) 3.01] per diseased tooth averted when compared with the status quo group. That is, after 6 years, an investment of S/.0.32 per annum per child would result in a net saving of S/.11.95 per decayed/missing/filled teeth prevented. While the analysis has inherent limitations as a result of its reliance on a range of assumptions, the findings indicate that for the situations prevailing in Peru, there are significant health and economic benefits to be gained from the use of salt fluoridation.

. To calculate the burden of smoking-related disease and evaluate the potential economic and health impact of tax-induced cigarette price increase in Peru. A microsimulation model was used to estimate smoking-attributable impact on mortality, quality of life, and costs associated with heart and cerebrovascular disease, chronic obstructive pulmonary disease, pneumonia, lung cancer, and another nine cancers. Three scenarios, involving increased taxes, were evaluated. . A yearly total of 16,719 deaths, 6,926 cancer diagnoses, 7,936 strokes, and 7,548 hospital admissions due to cardiovascular disease can be attributed to smoking in Peru. Similarly, 396,069 years of life are lost each year from premature death and disability, and the cost of treating smoking-attributable health issues rises to 2,500 million soles (PEN 2015). Currently, taxes on tobacco cover only 9.1% of this expense. If cigarette prices were to increase by 50% over the next 10 years, 13,391 deaths, 6,210 cardiovascular events, and 5,361 new cancers could be prevented, representing an economic benefit of 3,145 million (PEN) in savings in health costs and increases in tax revenues. . Smoking-attributable burden of disease and costs to the health system are very high in Peru. Higher cigarette taxes could have substantial health and economic benefits for the country.

Background In ethnobotanical research, the investigation into traditional knowledge of medicinal plants in the context of migration has been of increasing interest in recent decades since it is influenced and changed by new environmental and social conditions. It most likely undergoes transformation processes to match the different living circumstances in the new location. This study compares the traditional knowledge of medicinal plants held by Tyroleans – and their descendants – who emigrated to Australia, Brazil and Peru at different time scales. The study’s findings allow a discussion of the complexities and dynamics that influence this knowledge within the context of long-distance migration. Methods Information was obtained from 65 informants by free-listing, semi-structured interviews and non-participatory observation in Tyrol (Austria) and the migrants’ countries: Australia, Brazil and Peru. The collected data was analysed using different quantitative approaches, including statistical tests, and compared between the countries of investigation. Results All respondents in all four investigation areas claimed that they had knowledge and made use of medicinal plants to treat basic ailments in their day-to-day lives. Informants made 1,139 citations of medicinal plants in total in free lists, which correspond to 164 botanical taxa (genus or species level) in Tyrol, 87 in Australia, 84 in Brazil and 134 in Peru. Of all the botanical taxa listed, only five (1.1%) were listed in all four countries under investigation. Agreement among informants within free lists was highest in Tyrol (17%), followed by Peru (12.2%), Australia (11.9%) and Brazil (11.2%). The proportion of agreement differs significantly between informants in Australia and Tyrol (p = 0.001), Brazil and Tyrol (p = 0.001) and Peru and Tyrol (p = 0.001) and is similar between informants in the migrant countries, as indicated by statistical tests. We recorded 1,286 use citations

A Solar Station for Education and Research on Solar Activity at a National University in Peru
Ishitsuka, J. K.
2006-11-01
pepe@geo.igp.gob.pe Beginning in 1937, the Carnegie Institution of Washington made active regional observations with a spectro-helioscope at the Huancayo Observatory. In 1957, during the celebration of the International Geophysical Year Mutsumi Ishitsuka arrived at the Geophysical Institute of Peru and restarted solar observations from the Huancayo Observatory. Almost 69 years have passed and many contributions for the geophysical and solar sciences have been made. Now the Instituto Geofisico del Peru (IGP), in cooperation with the Faculty of Sciences of the Universidad Nacional San Luis Gonzaga de Ica (UNICA), and with the support of the National Astronomical Observatory of Japan, are planning to construct a solar station refurbishing a coelostat that worked for many years at the Huancayo Observatory. A 15 cm refractor telescope is already installed at the university, for the observation of sunspots. A solar Flare Monitor Telescope (FMT) from Hida Observatory of Kyoto University could be sent to Peru and installed at the solar station at UNICA. As the refurbished coelostat, FMT will become a good tool to improve education and research in sciences.

The majority of malaria rapid diagnostic tests (RDTs) detect Plasmodium falciparum histidine-rich protein 2 (PfHRP2), encoded by the pfhrp2 gene. Recently, P. falciparum isolates from Peru were found to lack pfhrp2 leading to false-negative RDT results. We hypothesized that pfhrp2-deleted parasites in Peru derived from a single genetic event. We evaluated the parasite population structure and pfhrp2 haplotype of samples collected between 1998 and 2005 using seven neutral and seven chromosome 8 microsatellite markers, respectively. Five distinct pfhrp2 haplotypes, corresponding to five neutral microsatellite-based clonal lineages, were detected in 1998-2001; pfhrp2 deletions occurred within four haplotypes. In 2003-2005, outcrossing among the parasite lineages resulted in eight population clusters that inherited the five pfhrp2 haplotypes seen previously and a new haplotype; pfhrp2 deletions occurred within four of these haplotypes. These findings indicate that the genetic origin of pfhrp2 deletion in Peru was not a single event, but likely occurred multiple times. PMID:24077522

Mobile Phones and Economic Development in Rural Peru
Beuermann, Diether W.; McKelvey, Christopher; Vakis, Renos
2012-01-01
We estimate the effects of mobile phone coverage on different measures of economic development. We exploit the timing of mobile coverage at the village level merging it with a village-level panel dataset for rural Peru. The main findings suggest that mobile phone expansion has increased household real consumption by 11 per cent, reduced poverty incidence by 8 percentage points and decreased extreme poverty by 5.4 percentage points. Moreover, those benefits appear to be shared by all covered h...

Eight Leishmania promastigotes were isolated from different geographical areas: three (LP1, LP2, and LP3) from the provincial department La Libertad and the fourth (LP4) from the department of Cajamarca (northern Peru); another three (LM1, LM2, and LM3) in the province of Campeche (Mexico); and the last (LS1) from a clinical case of a dog in Madrid (Spain). The isolates were characterized by carbohydrate cell-surface residues using agglutinations with four purified lectins, by isoenzyme analysis using different isoenzymes, by analysis of kinetoplast DNA (kDNA) restriction fragment length polymorphism using four different restriction endonucleases and by the final metabolite patterns after in vitro culture. These isolates were compared with four reference strains and typified as: Leishmania (Leishmania) donovani, two strains of L. (L.) infantum, and one species of L. (Viania) peruviana. According to our results and the statistical study, the Peruvian isolates represent three different strains: one would be L. (V.) peruviana, another the strain isolated in Cajamarca (LP4) and the third would include the three strains from the department of La Libertad (LP1, LP2, and LP3), these latter three isolates being phylogenetically closer to the reference strain L. (L.) donovani. Meanwhile, the three isolates from Mexico form a group with close phylogenetic relationships to each other. The isolate from Spain belongs to the species L. (L.) infantum. Thus, a close correlation was drawn between the identity of each strain and its geographical origin.

Biting midges (Diptera: Ceratopogonidae) were collected at 16 periurban and rural sites around Iquitos, Peru, between 17 October 1996 and 26 May 1997. Culicoides paraensis (Goeldi), the principal vector of Oropouche virus, was the most commonly collected species (9,086 flies) with Culicoides insinuatus Wirth & Blanton second (7,229 flies). Although both species were collected at all sampling sites (linear (distance surveyed approximately 25 km), C. paraensis dominated at northern collection sites (> 90%), whereas C. insinuatus prevailed at southern collection sites (> 60%). C. paraensis were collected from human sentinels at a constant rate throughout daylight hours, at similar rates during wet and dry months, and regardless of rainfall. Larval developmental substrates for C. paraensis included decaying platano (Musa x paradisiaca L. [Musaceae]) stems, stumps, flowers, fruits, and debris beneath platano trees as well as from soil beneath a fruiting mamay (Syzygium malaccense Merr. & Perry [Myrtaceae] ) tree and organic-rich mud along a lake shoreline. C. insinuatus adults likewise emerged from decaying platano and organic-rich mud along a lake shoreline, but also from debris accumulated in the axils of aguaje (Mauritia flexuosa L. [Palmae]) fronds and decaying citrus fruit. Despite high numbers of biting adults near putative substrates, adults of neither species emerged from other decomposing plant material, soil, phytotelmata, or artificial containers. Because both species of biting midges emerged in high numbers from all parts of platano (ubiquitous in Iquitos), it will be challenging to control them through sanitation.
