Tropical forests harbour thousands of useful plants which are harvested and used in subsistence economies or traded in local, regional or international markets. The effect on the ecosystem is little known, and the forests resilience is badly understod. Palms are the most useful group of plants in tropical American forests and we will study the effect of extraction and trade of palms on forest in the western Amazon, the Andes and the Pacific lowlands. We will determine the size of the resource by making palm community studies in the different forest formations and determine the number of species and individuals of all palm species. The genetic structure of useful palm species will be studied to determine how much harvesting of the species contributes to genetic erosion of its populations, and whether extraction can be made without harm. We then determine how much palms are used for subsistence purposes by carrying out quantitative, ethnobotanical research in different forest types and then we study trade patterns for palm products from local markets to markets which involve export to other countries and continents. Palm populations are managed in various ways from sustainable ones to destructive harvesting; we will study different ways in which palms are managed and propose sustainable methods to local farmers, local governments, NGOs and other interested parties. Finally we will study national level mechanism that governs extraction, trade and commercialization of palm products, to identify positive and negative policies in relation to resilience of ecosystems and use this to propose sustainable policies to the governments. The results will be diseminated in a variety of ways, depending on need and stake holders, from popular leaflets and videos for farmers, reports for policy makers to scientific publication for the research community. The team behind the proposal represents 10 universities and research institutions in Europe and northwestern South America.

Background: The clinical and epidemiologic characteristics of pediatric sporotrichosis are poorly understood. Objective: To describe the incidence and clinical characteristics of cases of sporotrichosis in children 14 years of age and younger reported in Abancay from 2004 to 2011, stratified according to age. Methods: We performed a retrospective review of pediatric patients 14 years of age and younger who were diagnosed with sporotrichosis in a referral center at Abancay, a poor area located in the south central highlands of Peru, to estimate the incidence rates (per 100,000 person-years) according to age and sporotrichosis type (lymphocutaneous and fixed), and clinical characteristics of these patients. Results: Of the 240 pediatric cases identified, 131 (54.6%) were male. The median age at baseline was 6 years. The mean incidence rate was 81.4 cases per 100,000 person-years for the period from 2004 to 2011, and was highest among children ranging in age from 5-9 years. The incidence of lymphocutaneous sporotrichosis and fixed sporotrichosis was 55 and 27 cases per 100,000 person-years, respectively, and the face was the most commonly affected anatomic site. Ninety-six of the 240 patients (40%) reported previous contact with cats, and 46 (19.2%) had a clear history of traumatic inoculation with plant material. The therapeutic response to treatment with potassium iodide was satisfactory. Conclusion: In this retrospective study, we described a high incidence of sporotrichosis in children in the south central highlands of Peru, which increased with age. Lymphocutaneous sporotrichosis was the more common type with an incidence rate twice that of the fixed type. The face was the most commonly affected anatomic site, and infection appeared to be acquired predominantly through contact with cats. © 2017 International Society of Dermatology.

Orthopathy appeared in Peru in the 19th century in various guises and different spheres that transcended the activities of doctors. Sebastián Lorente, a doctor and educator, promoted hygiene education for schoolchildren through the publication of a Catechism of Hygiene, which went through multiple editions in the second half of the century. The structure and content of the Catechism is linked to European medical traditions such as the miasmatic interpretation of diseases, but also to local traditions like the medical topography of Hipólito Unanue, both of which had a vision of imposing “healthy” behaviors on the population, which assimilated the work of Johann Peter Frank. © 2017, Instituto Nacional de Salud.

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. © 2014, Instituto Nacional de Salud.

The growth of children living in Nuñoa, a Peruvian high-altitude community, was studied over a 35-year period using data collected in 1964 and 1999. There had been evidence of a secular trend in growth in the mid-1980s, but this was before a period of sociopolitical upheaval lasting until the late 1990s partly linked to the activities of the Shining Path group and the Peruvian government's response. Anthropometric data for 576 children examined in 1964-1966 were compared with data from 361 children examined in 1999. Data were converted to Z Scores using NCHS/WHO reference standards. Compared with the 1964 cohort, boys in 1999 had marginally greater height Z Scores, but among females, the trend was reversed. Stunting prevalence had decreased from 1964 levels, but still approached 60% in both sexes, among the highest rates recorded for a modern world population. The prevalence of low weight for height was less than expected, possibly because of the compensatory effect of enlarged chest diameter. This anatomical feature may represent the effect of chronic hypoxic stress, causing growth of the chest cavity at the expense of growth in height. In view of modest improvements during the late 1980s in this population, we believe that the relatively poor growth status of children a decade later may result from food disruption associated with later political instability. Compared with children in a nearby community, which benefits from the socioeconomic infrastructure associated with a large copper mine, Nuñoa children continue to fare relatively poorly. © 2009 Wiley-Liss, Inc.

Animals often use signals to communicate their dominance status and avoid the costs of combat. We investigated whether the frequency of the electric organ discharge (EOD) of the weakly electric fish, Sternarchorhynchus sp., signals the dominance status of individuals. We correlated EOD frequency with body size and found a strong positive relationship. We then performed a competition experiment in which we found that higher frequency individuals were dominant over lower frequency ones. Finally, we conducted an electrical playback experiment and found that subjects more readily approached and attacked the stimulus electrodes when they played lowfrequency signals than high-frequency ones. We propose that EOD frequency communicates dominance status in this gymnotiform species. © 2011 The Royal Society.

In this paper we present an extension of the proximal point algorithm with Bregman distances to solve constrained minimization problems with quasiconvex and convex objective function on Hadamard manifolds. The proposed algorithm is a modified and extended version of the one presented in Papa Quiroz and Oliveira (J Convex Anal 16(1): 49-69, 2009). An advantage of the proposed algorithm, for the nonconvex case, is that in each iteration the algorithm only needs to find a stationary point of the proximal function and not a global minimum. For that reason, from the computational point of view, the proposed algorithm is more practical than the earlier proximal method. Another advantage, for the convex case, is that using minimal condition on the problem data as well as on the proximal parameters we get the same convergence results of the Euclidean proximal algorithm using Bregman distances. © 2012 Springer Science+Business Media New York.


Background: HIV-associated cognitive impairment occurs even in the early stages of infection. Short-term memory, psychomotor speed, attention, and executive functioning are the main capacities affected. Controversy exists regarding whether highly active antiretroviral therapy (HAART) is helpful in combating this process. The objective of the present study is to determine the association between cognitive impairment and HAART in HIV-infected patients from Hospital Regional de Huacho. Methods: Prospective study of HIV patients meeting criteria to start HAART. Twenty-one HIV-positive patients were recruited between April and July 2011. Researchers administered a standardised neuropsychological test battery before and 4 weeks after onset of HAART. Psychomotor speed, executive function, short term memory (visual and verbal), attention, and visuospatial performance were evaluated. Results: Nineteen patients completed the study (14 males and 5 females). In the pre-HAART evaluation, most patients scored below average on the executive function and psychomotor speed subtests. Psychomotor speed and immediate visual memory improved significantly after four months of treatment with HAART. Conclusions: Some degree of cognitive decline may present even in the early and asymptomatic stages of HIV infection. The benefits of antiretroviral treatment for cognitive performance can be detected after only a few weeks of follow-up. © 2013 Sociedad Española de Neurología.

Purpose To describe the clinical and epidemiologic characteristics of sporotrichosis in ocular adnexa and give an insight into factors associated with this condition. Design Retrospective case series and literature review. Methods We retrospectively reviewed all cases of sporotrichosis in ocular adnexa between 2004 and 2014 in the Santa Teresa Clinic of Abancay, Peru and reviewed all case reports of sporotrichosis in ocular adnexa in the literature. Results We reviewed records of 21 patients with sporotrichosis in ocular adnexa; 12 (57.1%) of them were male and their median age surrounded 9 years. In our series, 19 patients had lesions in the eyelids and 2 in the eyebrows. The lymphocutaneous form occurred in 62% of them. Ten patients (47.6%) were cured with potassium iodide. Among 65 patients with sporotrichosis in ocular adnexa (our 21 patients and 44 from the literature), the average age was 9 years, and 78% were ≤15 years of age; 54% were male. The lesions were more frequent on the eyelids (n = 53 [82%]), followed by the lacrimal gland (n = 5), conjunctiva (n = 4), and eyebrows (n = 3). The lymphocutaneous clinical form (54%) was the most frequent. Fifty patients were cured: 31 of them with potassium iodide, 16 with itraconazole, and 3 with a combination including potassium iodide, itraconazole, and fluconazole. Twenty-nine patients (44.6%) resided in a hyperendemic region, and 5 patients reported contact with cats that had sporotrichosis. Conclusions Sporotrichosis in ocular adnexa is associated with children ≤15 years of age, and in 82% of these cases the disease is limited to the eyelids. © 2016 Elsevier Inc.
