- Tesis Título Profesional Acceso EmbargadoFactores personales y sobrecarga del cuidador a personas con trastorno mental residentes en hogares protegidos de salud mental Iquitos 2025(Universidad Nacional de la Amazonía Peruana, 2026) Moreno Vela, Graciela del Carmen; Reátegui Yomona, Evelin Gabriela; Matute Panaifo, Eva LucíaThis research aimed to determine the relationship between personal factors and caregiver burden experienced by caregivers of individuals with mental disorders residing in mental health shelters in Iquitos, 2025. It was a quantitative, descriptive, non-experimental, correlational, and cross-sectional study with a sample of 32 caregivers. The survey technique was used. The instruments applied were the Stress Test - Reactivity Index, the Coopersmith Self-Esteem Scale for Adults, and the Zarit Caregiver Burden Scale. The results showed that the majority of caregivers were between 36 and 45 years old (62.5%), and less frequently between 56 years old and older (9.4%). Most caregivers were female (68.8%). Their economic situation was medium to good (43.7%), and minimal (12.6%). All caregivers reported low stress levels (100%), and low self-esteem (68.8%). Regarding caregiver burden, 50% reported no burden, followed by mild burden (31.2%) and a minimal amount of severe burden (18.8%). When relating personal factors to caregiver burden, a statistically significant relationship was found between stress, self-esteem, and burden (X² = 32.0; p < 0.001). This confirms the existence of a statistically significant relationship between the personal factors of stress, self-esteem, and caregiver burden, thus supporting the research hypothesis.
- Tesis Título Profesional Acceso EmbargadoValidación de una aplicación móvil con redes neuronales artificiales para el diagnóstico microscópico de malaria(Universidad Nacional de la Amazonía Peruana, 2026) Ramírez Calderón, Carlos Daniel; Rodríguez Ferrucci, Hugo Miguel; Cárdenas Vigo, RodolfoBackground: Malaria remains a major public health problem in the Peruvian Amazon, where timely diagnosis is limited by geographic barriers, a shortage of trained microscopists, and variability in routine microscopy. Methods: A quantitative, retrospective, analytical, observational, cross sectional study was conducted to evaluate the diagnostic performance of an artificial intelligence–based mobile application for microscopic malaria detection in thick blood smear slides, operated by non-expert users, using expert microscopy as the reference standard. A total of 397 slides from Intuto, Loreto, Peru, were included after data cleaning and quality control. Results: According to the reference standard, 205 slides were positive and 192 were negative. The mobile application achieved an overall accuracy of 77.3%, with a sensitivity of 71.2%, specificity of 83.9%, positive predictive value of 82.5%, negative predictive value of 73.2%, F1-score of 0.764, Youden index of 0.551, and Cohen’s kappa of 0.548. Sensitivity improved with increasing parasitemia. The Intuto laboratory outperformed the mobile application across the main diagnostic metrics. Conclusions: The mobile application demonstrated moderate diagnostic performance under real-world conditions, and parasitemia was identified as the main determinant of detection. Although it does not currently support autonomous clinical use, it may be useful as a complementary screening or decision-support tool in remote settings
- Tesis Título Profesional Acceso EmbargadoNiveles de harina de cáscara de plátano en ración de broilers e implicancia en los parámetros productivos, en Yurimaguas(Universidad Nacional de la Amazonía Peruana, 2026) Rios Flores, Maria Elvira; Macedo Córdova, WilderThe experiment was conducted at the Yurimaguas Research and Teaching Center (CIEY), Km 17 Farm, Faculty of Animal Science of the National University of the Peruvian Amazon, over a 42-day period, with the aim of evaluating the effect of green banana peel meal inclusion in broiler diets on feed intake, body weight gain, and feed conversion ratio. A total of 96 birds were assigned under a Completely Randomized Design with four treatments (0, 5, 10, and 15%) and four replicates. During the starter phase, feed intake ranged from 1.61 to 1.74 kg/bird with no statistical differences, while body weight gain varied from 0.86 to 0.97 kg, showing a similar response among diets. From 21 to 42 days, intake increased to 3.03–3.40 kg, with higher values observed at greater inclusion levels, whereas weight gain ranged from 1.71 to 1.92 kg, without significant treatment effects. Feed conversion ratio showed the best values in the control group (1.68 in the starter phase; 1.06 in the finisher phase; 1.63 overall), although differences compared to diets containing banana peel meal were moderate. It is concluded that banana peel meal can be included at levels of up to 15% without significantly compromising productive performance, representing a feasible alternative for the utilization of agro-industrial by-products in commercial poultry feeding systems.
- Tesis Título Profesional Acceso EmbargadoÍndice neutrófilo/linfocito como biomarcador predictor de apendicitis aguda complicada en el Hospital Regional de Loreto, 2023-2024(Universidad Nacional de la Amazonía Peruana, 2026) Acosta Rios, Piero Alejandro; Valera Tello, Eduardo AlbertoAcute appendicitis is one of the leading causes of emergency abdominal surgery; however, differentiating between its complicated and uncomplicated forms remains a clinical challenge, as delayed diagnosis is associated with increased morbidity and prolonged hospital stay. In this context, the neutrophil-to-lymphocyte ratio (NLR) has been proposed as an accessible and low-cost inflammatory biomarker with potential diagnostic value. The aim of this study was to determine the predictive capacity of the NLR for complicated acute appendicitis in patients treated at the Hospital Regional de Loreto during 2023–2024. An observational, analytical, retrospective, and cross-sectional study was conducted, including 565 patients with surgically confirmed acute appendicitis. Predictive capacity was evaluated using receiver operating characteristic curve analysis, from which the optimal cut-off point was determined. Patients with complicated appendicitis showed significantly higher NLR values compared to those with uncomplicated forms (mean rank: 124.07 vs. 76.93; p < 0.001). A value greater than or equal to 8 was significantly associated with complicated appendicitis. The analysis demonstrated an area under the curve of 0.736 (95% confidence interval: 0.667–0.804; p = 0.035), indicating acceptable discriminative capacity. The NLR is a useful biomarker for predicting complicated acute appendicitis.
- Tesis Título Profesional Acceso EmbargadoInfluencia de la fertilización fosfórica sobre la producción forrajera y nutricional del pasto maralfalfa en el CIEY-UNAP, Yurimaguas(Universidad Nacional de la Amazonía Peruana, 2026) Ruiz Huaranga, Juana Iris; Macedo Córdova, WilderThe study evaluated the effect of four doses of rock phosphate (T1: 0 kg RP/ha, T2: 100 kg RP/ha, T3: 150 kg RP/ha, and T4: 200 kg RP/ha) on the production and quality of maralfalfa grass at 45 and 60 days. At 45 days, green matter production in T1 was 9.68 Tn/ha, while the fertilized treatments reached higher values, with T3 standing out at 28.98 Tn/ha; however, no statistically significant differences were found (P > 0.05). At 60 days, T3 again showed the highest numerical value at 53.65 Tn/ha, surpassing T1 (30.55 Tn/ha), T2 (24.80 Tn/ha), and T4 (29.95 Tn/ha), although this difference was not statistically significant. Dry matter content at 45 days was highest in treatment T3 (5.18 Tn/ha), compared to 3.10 Tn/ha in T1. At 60 days, T3 again showed the highest value at 12.70 Tn/ha, demonstrating a clear numerical superiority, although without statistical significance (P > 0.05). Regarding protein content, at 45 days T3 presented the highest percentage (12.14%), without statistical significance; however, at 60 days significant differences were observed (P < 0.05), where T3 (8.32%) and T4 (8.06%) surpassed the control (7.16%). Finally, phosphorus content showed a dose-dependent response, with T4 being the treatment with the highest content at 45 days (0.43%) and at 60 days (0.25%), with statistically significant differences among all treatments in this latter evaluation. Overall, T3 stood out as the best in terms of productivity and protein content, while T4 was superior in phosphorus accumulation.
