EVALUACIÓN DEL PRENDIMIENTO Y DESARROLLO DE CLONES DE CAUCHO (Hevea brasiliensis) PROPAGADOS POR INJERTO EN LA SELVA PERUANA

<p><strong>Background.</strong> The latex yield in <em>Hevea brasiliensis</em> trees is highly variable; Therefore, it is important to propagate commercial clones of this species by grafting in order to standardize or improve latex yields and therefore improve the economic income of producers in this part of the Amazon region. <strong>Objective.</strong> To evaluate the attachment and development of rubber clones propagated by grafting in the Peruvian jungle. <strong>Methodology.</strong> Nine-month-old patterns installed in the field were used. These were grafted with budding rods from the commercial clones TR-1, FX-3864, RRIM-600, IAN-873 and MDF-180. A completely randomized block design was used with five treatments and three blocks with 15 experimental units; each containing 30 repetitions. The data obtained were subjected to analysis of variance and Tukey's multiple range test (p<0.05) and the Kruskal Wallis test. <strong>Results.</strong> The best results in attachment and number of shoots were obtained in grafts with clone MDF-180 with values of 73.33 % and 7.83 shoots respectively; Regarding days to the appearance of the shoot and length, clone TR-1 presented it with 36.63 days and 27.47 cm; The largest leaf area was presented by the graft with clone IAN-873 with 55.46 cm<sup>2</sup>, while the highest chlorophyll content was obtained in grafts with clone RRIM-600 with 47.18 SPAD. <strong>Implications</strong>. More studies are required to establish the quality and adaptability of rubber clones propagated by grafting in different site conditions and establish patterns of tree productivity in a short time; Likewise, it is desired to evaluate the quality and quantity of latex produced by these clones. <strong>Conclusions.</strong> These results indicate the feasibility of propagating <em>Hevea brasiliensis</em> through shoot grafting in the field, which opens great possibilities for propagating rubber trees with better commercial characteristics, particularly with greater latex production.</p>

Iron deficiency anemia as a risk factor for pulp disease in children from the central Peruvian jungle: a case‒control study.

To investigate iron-deficiency anemia as a risk factor for dental pulp disease in children from the central Peruvian jungle. A case-control study was carried out with 270 children, of which 90 referred to cases and 180, to controls. Patients with pulp disease were diagnosed according to the criteria of the Association of Endodontists and the American Board of Endodontics. A specific questionnaire was used to assess ferrous sulfate consumption, maternal education level, maternal age, occupation, and household income. Data were analyzed using Pearson's correlation coefficient and a binary logistic regression. Iron deficiency anemia offers a risk factor for pulp disease in children (OR 7.44, IC 95% 4.0-13.8). According to multivariate analysis using binary logistic regression, ferrous sulfate consumption (OR 13.8, IC 95% 5.6.33.9), maternal education level (OR 2.4, IC 95% 1.1-5.3), maternal age (OR 7.5, IC 95% 2.9-19.4), household income (OR 4.0, IC 95% 1.6-9.6), and caries (OR 10.7, IC 95% 4.5-25.7) configured independent factors that were statistically associated with pulp disease. Iron deficiency anemia, ferrous sulfate consumption, maternal education level, maternal age, household income, and dental caries were positively associated with pulp disease in children.

Teleodontology in the Central Peruvian Jungle: Quality and Service Satisfaction

The research analyzes the teledentistry service applied in health services during COVID-19, studying the quality of the teledentistry service and the level of satisfaction of patients treated with this care model. A sample of 341 patients was worked on, using the SERVQUAL model. The results showed a statistically significant relationship between quality of service in teledentistry and patient satisfaction (p<0.05), where 34.9% patients perceived low quality of service and dissatisfaction, while 33.7% were pleased with the care. We conclude that, given the dental health difficulties, the population of the Peruvian central jungle is dissatisfied with the teledentistry service.

Spatial analysis of hypertension in Peruvian adults, 2022

To perform a spatial analysis of arterial hypertension in the Peruvian adult population to identify geographic patterns with a higher concentration of cases. A spatial analysis was conducted using data from the Demographic and Family Health Survey (ENDES) 2022. A sample of 29,422 adults was included, and the global Moran's index and Getis-Ord Gi* analysis were used to evaluate spatial autocorrelation and cluster concentration. The age-standardized prevalence of arterial hypertension was 19.2%. Clusters with a high concentration of arterial hypertension were observed in departments along the Peruvian coast such as Tumbes, Piura, Lambayeque, La Libertad, Ancash, and Lima, as well as in the northern regions of the Highlands. Clusters were also found in the regions of Loreto and Madre de Dios in the Peruvian jungle. This study revealed geographic patterns of arterial hypertension in Peru, with a higher concentration of cases along the Peruvian coast and in certain regions of the Highlands and Jungle. These findings highlight the need to develop strategies for the prevention and control of the disease, especially in the areas identified as high-prevalence clusters.

COVID-19 may lower quality of life when infections and deaths increase: A longitudinal study in the Peruvian jungle.

Quality of life (QoL) is a multifactorial concept on the perception of the individual's wellbeing underpinned by environmental, psychological, and physical factors. Several studies have shown changes in QoL in the COVID-19 pandemic and may be due to increases in mortality rates, however, no study has investigated this among Peruvian jungle dwellers. Here, we have sought to estimate the QoL of individuals before and after the increase in cases and deaths from COVID-19. A questionnaire-based longitudinal study was conducted in 102 inhabitants (mean 40.75 ± 7.49 years). The Spanish version of the WHOQOL-BREF was used in two stages: April and June. The first stage was accomplished before the first confirmed case of COVID-19, and the second stage was when the daily mortality rate was 3.5% with an incidence of 87%. Sixty (54.8%) participants were women, 67 (61.9%) were >31 years, and 38 (34.5%) and 32 (29.1%) participants had primary and secondary education, respectively. In the first and second stage we obtained an overall mean QoL of 46.65 ± 23.2 and 35 ± 27.7 points, respectively. Individuals had significantly lower QoL in the face of increased deaths in physical (p = 0.001), mental (p = 0.028) and environmental (p = 0.001) health domains, with the latter having the greatest impact (51.84 ± 5.81 vs. 16.66 ± 5.55 points). Quality of life of Peruvian jungle dwellers is reduced during periods of increased mortality and incidence by COVID-19. Preventive strategies aimed at reducing the impact of COVID-19 on the mental health and global wellbeing of individuals living in the Amazon are recommended to Peruvian authorities.

Agricultural associations and fair trade in the Peruvian rainforest: a socioeconomic and ecological analysis

Fair trade initiatives represent an essential support for the scarce opportunities that have arisen in the agricultural sector, as they cover various areas that contribute to increasing good trade practices. It is essential to highlight the contribution of fair trade in urban and rural areas, as it becomes a valuable incentive for differentiation. The main objective of this study was to determine how Fair Trade is applied in the socioeconomic and ecological sphere in an association of sustainable agricultural producers in the Peruvian jungle. This is quantitative research with a non-experimental cross-sectional design. The survey technique was used, and a questionnaire was applied to 99 agricultural producers in the Amazon region of northern Peru, because it would help to analyze the new challenges of fair trade. In addition, data analysis and processing was carried out with Microsoft Office Excel and SPSS. The results show that 51% of the producers surveyed have been sensitized to adopt socially responsible actions aimed at strengthening sustainable development, social responsibility and good practices for fair trade in favor of the preservation of the resources of the Peruvian Amazon, as well as the socioeconomic development of farmers and the region itself. Forty-seven percent carry out social responsibility activities under the guidance of the Fairtrade organization, which has accompanied farmers to obtain Fairtrade certification. In addition, 59% of respondents say that they engage in healthy competition that generates trust among farmers. Fairtrade enables associated farmers to improve their ethical behavior and respect for their rights as well as those of the entire community.

The odds of accident-type casualties in a Peruvian jungle road

The current analysis analyzed the odds of casualties by road accidents. Hence, data were classified into tertiles for better research, and accident types were classified into five following the authority methodology: rollovers, crash, roadway departure, special accident, and car capsizing. Multi-logistic regression was employed for the data analysis. This research found that rollover was the most deadly accident, and the crash was the most probable to cause injuries.

Characterization of the bacterial microbiome of Amblyomma scalpturatum and Amblyomma ovale collected from Tapirus terrestris and Amblyomma sabanerae collected from Chelonoidis denticulata, Madre de Dios- Peru

BackgroundTicks are arthropods that can host and transmit pathogens to wild animals, domestic animals, and even humans. The microbiome in ticks is an endosymbiotic, pathogenic and is yet to be fully understood.ResultsAdult male Amblyomma scalpturatum (A. scalpturatum) and Amblyomma ovale (A. ovale) ticks were collected from Tapirus terrestris (T. terrestris) captured in the rural area of San Lorenzo Village, and males Amblyomma sabanerae were collected from Chelonoidis denticulate (C. denticulate) of the Gamita Farm in the Amazon region of Madre de Dios, Peru. The Chao1 and Shannon–Weaver analyses indicated a greater bacterial richness and diversity in male A. sabanerae (Amblyomma sabanerae; 613.65–2.03) compared to male A. scalpturatum and A. ovale (A. scalpturatum and A. ovale; 102.17–0.40). Taxonomic analyses identified 478 operational taxonomic units representing 220 bacterial genera in A. sabanerae and 86 operational taxonomic units representing 28 bacterial genera in A. scalpturatum and A. ovale. Of the most prevalent genera was Francisella (73.2%) in A. sabanerae, and Acinetobacter (96.8%) in A. scalpturatum and A. ovale to be considered as the core microbiome of A. sabanerae and A. scalpturatum/A. ovale respectively.ConclusionsWe found a high bacterial diversity in male of A. sabanerae collected from C. denticulata showed prevalence of Francisella and prevalence of Acinetobacter in male A. scalpturatum and A. ovale collected from T. terrestris. The greatest bacterial diversity and richness was found in males A. sabanerae. This is the first bacterial metagenomic study performed in A. scalpturatum/A. ovale and A. sabanerae collected from T. terrestris and C. denticulata in the Peruvian jungle.

No cumplimiento del esquema de vacunación nacional en niños menores de 5 años en la selva peruana en el año 2019

In the past decade, levels of coverage on children vaccination had been decreasing nationwide, even more in the Peruvian jungle, reason why is an important public health’s subject to attend. The purpose of this investigation was to analyze maternal and social factors that are associated with incomplete vaccination schedules on children under 5 years old on the Peruvian jungle. It is an observational, analytic investigation, using a secondary source from the Demographic and Family survey (ENDES) from 2019, where is found the information of all the under 5 years old with the healthcare card of oral information given by the mother. Then after selecting the chosen variables, we used the SPSS statistic program for the posterior analysis. Of the 4373 surveys studied; it was shown that 57.5% of children under 5 years have the incomplete vaccination schedule. The multivariate analysis found that non-compliance with the vaccination schedule associated with maternal and social factors such as not having health insurance (ORa 1.72; p<0.01, IC95% 1.39-2,13), poverty (ORa-1,427, p<0.01, IC95% 1.89-1.71), native mother tongue (ORa-1.50, p<0.01, IC-1.13-2,0), problems attending the health center (ORa-1,213, p=0.02, IC95% 1.02-1.44), live outside the city (ORa-1.31, p<0.01, IC95% 1.09- 1.58), age under the age of 24 as a mother/guardian (ORa-1.38, p<0.01, IC95% 1,186-1,619). Not having health insurance, living in poverty, having trouble going to the health center, living outside the city, having a different mother tongue than Spanish and age under 24 are factors associated with non-compliance with the vaccination schedule.

Riverside protection by means of gabions in a stream of the Peruvian jungle.

The objective of this work was to determine a design for a riparian protection infrastructure using gabions in the Peruvian jungle. The methodology used was of an applied, quantitative type, the sample is the area between kilometers 1,060 and 1,660 of the Chaupimayo creek, Madre de Dios, Peru. The conclusionswere that the soil on the surface is clayey sand (SC) and the depth is silty gravel (GM), the micro-basin has an area of 0,365 km2, and a perimeter of 3,03 km. Likewise, it was obtained that the design base will be made up of two types of A gabion of 1,00 m x 1,00 m, and the second level will be made up of a type B gabion of 1,50 m x 1.00 m. In the highest part by a type A gabion, the structure will have a type C mattress of 1,00 m x 0,50 m.

ABSORCIÓN DIFERENCIADA DE CADMIO Y SU EFECTO EN LA FISIOLOGÍA DE SEIS GENOTIPOS DE CACAO (Theobroma cacao L.) EN SAN RAMÓN, SELVA CENTRAL DEL PERÚ

<p><strong>Background.</strong> Cacao is an important source of income, especially for small farmers in developing countries. However, its commercialization, and consequently its production, is threatened by the high levels of cadmium (Cd<sup>+2</sup>) in grains. <strong>Objective. </strong>This work was carried out with the objective of determining the differentiated uptake of six cacao genotypes in San Ramón, central Peruvian jungle. <strong>Methodology.</strong> The treatments consisted of the combination of different doses Cd<sup>+2</sup> (0, 50, 100 and 150 ppm) with the genotypes CCN-51, ICS-60, ICS-95, POUND-7 and VRAE-99. <strong>Results.</strong> The results indicate that POUND 7 absorbed a greater amount of Cd<sup>+2</sup> concentrated mainly in the root, while CCN-51 concentrated it mainly in the aerial tissues. In VRAE-99, a significant drop in stem height and diameter was observed, especially at the 150 ppm dose. This genotype was shown to be more sensitive to this metal at high doses (150 ppm) and decreased its photosynthetic rate and its efficiency in the use of water, which was confirmed by the increase in the internal carbon content. <strong>Implications.</strong> In general, it was found that POUND-7 is a promising genotype that can potentially be used as a rootstock because it is capable of accumulating Cd+2 mainly in the roots. <strong>Conclusion.</strong> Although cacao is considered a Cd<sup>+2</sup> accumulator plant, this heavy metal can negatively affect the physiology of the plant as in the case of VRAE-99. Further studies are suggested to better understand how Cd<sup>+2</sup> affects cacao physiology.</p>

Genetic diversity and population structure of Leishmania (Viannia) braziliensis in the Peruvian jungle.

BackgroundHuman cutaneous leishmaniasis caused by Leishmania (Viannia) braziliensis is highly prevalent in the Peruvian jungle, where it affects military forces deployed to fight against drug trafficking and civilian people that migrate from the highland to the lowland jungle for economic activities such as mining, agriculture, construction, and chestnut harvest.We explored the genetic diversity and population structure of 124 L. (V.) braziliensis isolates collected from the highland (Junín, Cusco, and Ayacucho) and lowland Peruvian jungle (Loreto, Ucayali, and Madre de Dios). All samples were genotyped using Multilocus Microsatellite Typing (MLMT) of ten highly polymorphic markers.Principal findingsHigh polymorphism and genetic diversity were found in Peruvian isolates of L. (V.) braziliensis. Most markers are not in Hardy-Weinberg equilibrium; this deviation is most likely caused by local inbreeding, as shown by the positive FIS values. Linkage Disequilibrium in subpopulations was not strong, suggesting the reproduction was not strictly clonal. Likewise, for the first time, two genetic clusters of this parasite were determined, distributed in both areas of the Peruvian jungle, which suggested a possible recent colonization event of the highland jungle from the lowland jungle.ConclusionsL. (V.) braziliensis exhibits considerable genetic diversity with two different clusters in the Peruvian jungle. Migration analysis suggested a colonization event between geographical areas of distribution. Although no human migration was observed at the time of sampling, earlier displacement of humans, reservoirs, or vectors could have been responsible for the parasite spread in both regions.
