Análisis del consumo de café y su relación con los efectos en la salud en personas con hipertensión arterial que acuden a boticas de la urbanización Los Alisos. Callao, 2024
(Universidad Privada Norbert Wiener, 2025-04-11) Bonilla Mundaca, Lucerito Mayde; Mamani Yauyos, Julia Cristina; Llahuilla Quea, José Antonio
El café se ha establecido como una de las bebidas más populares y consumidas en todo el mundo y ha sido objeto de estudios sobre su impacto en la salud cardiovascular, especialmente en la presión arterial. A pesar de su alta prevalencia, los efectos de la cafeína sobre el riesgo de hipertensión siguen siendo inciertos. Algunos estudios sugieren que el consumo regular de café podría aumentar este riesgo, mientras que otros no encuentran una relación significativa. Esta falta de consenso es preocupante, ya que la hipertensión es un factor clave en las enfermedades cardiovasculares, principales causas de morbilidad y mortalidad global. Objetivo: “Evaluar la relación entre el consumo del café y efectos en la salud en personas con hipertensión arterial”. Metodología: Esta investigación de tipo básica empleó un enfoque cuantitativo y un método hipotético - deductivo, con un diseño no experimental de corte transversal, cuyo alcance fue descriptivo – correlacional, mediante la aplicación de 384 encuestas a personas con hipertensión arterial consumidoras de café que acuden a las diferentes boticas de la urbanización Los Alisos, Callao. Resultados: Se obtuvo una relación directa y significativa (Rho=0,512), indicando que un mayor consumo de café (tiempo, frecuencia y tipo) se relaciona con mayores efectos en la salud. Conclusión: El consumo de café se relaciona con los efectos en la salud en personas con hipertensión arterial que acuden a las boticas de la urbanización Los Alisos, respaldado por el p valor <0,05 rechazando la hipótesis nula.

Exposure to ionizing radiation and its effect on the health of healthcare workers
(Universidad Privada Norbert Wiener, 2017-12-03) Cortabrazo Asencio, Roxana Jacqueline; La Madrid Sanchez, Kattia Angelica; Borda Izquierdo, Alejandro
Objective: To systematize the available evidence on the effect of exposure to ionizing radiation on the health of healthcare workers. Materials and Methods: This work involves systematic reviews, with an observational and retrospective design, synthesizing the results of multiple studies. These are essential to Evidence-Based Nursing (EBN) due to their rigorous methodology, identifying relevant studies to address specific clinical practice questions. The search was restricted to full-text articles, which were critically assessed using the GRADE system to assign the strength of recommendations. Results: Ten scientific articles were reviewed; 20% (2) were from Colombia, 20% (2) from Spain, 20% (2) from Cuba, 10% (1) from Argentina, 10% (1) from Brazil, 10% (1) from the United States, and 10% (1) from Peru. Nine studies were systematic reviews (90%) and one study was quantitative, descriptive, cross-sectional, correlational, and retrospective (10%). According to the results, 100% (10) of the studies showed that exposure to ionizing radiation has a negative effect on the health of healthcare workers, causing harmful damage such as thyroid cancer, hyperthyroidism, gastric intestinal metaplasia, chromosomal aberrations, apoptosis, mutations, genomic instability, male infertility, and leukemia. Conclusions: Ionizing radiation exposure has a negative effect on healthcare workers' health; inappropriate and irrational use can lead to severe health consequences due to genotoxic and carcinogenic effects that increase frequently with prolonged exposure over days, months, and years. Therefore, safety measures must always be in place to prevent these effects.

Quality of life and family functionality in patients with chronic renal insufficiency undergoing hemodialysis treatment at the Francisco de San Juan de Lurigancho Clinic, Lima - 2021
(Universidad Privada Norbert Wiener, 2021-11-28) Vilca Moreno, Evelyn Rocio; Fernández Rengifo, Werther Fernando
Introduction: Chronic kidney disease not only causes serious consequences for the patient in all dimensions of their health and quality of life, but it also directly involves their immediate family environment. Renal replacement through hemodialysis is a therapeutic alternative, but it affects the lifestyle and quality of life of the patient and their family members, who play a fundamental role that can have a positive or negative impact on the patient. Objective: To determine how quality of life is related to family functionality in patients with chronic kidney failure undergoing hemodialysis treatment at the Francisco I Clinic in San Juan de Lurigancho, Lima – 2021. Methods: The study will be observational, descriptive, relational, and cross-sectional. An intentional sample of 90 patients with chronic kidney disease undergoing hemodialysis replacement therapy will be selected between October and December 2021. A survey using validated and reliable instruments will be applied to estimate health-related quality of life through the KDQOL-36 questionnaire, developed by the Kidney Disease Quality of Life Working Group. It is an abbreviated version of the KDQOL-SF, with 36 items, designed for use with dialysis patients, which helps reduce interview time and optimize acceptance. To estimate family functioning, the Family Apgar instrument will be used, a useful psychometric tool that shows how family members perceive the overall level of functioning or functionality of the family unit.

Relación entre los índices plaquetarios y los niveles de dímero D en pacientes con sepsis en el Hospital PNP Luis N. Sáenz, 2024
(Universidad Privada Norbert Wiener, 2025-12-04) Vino Sánchez, Martha María; Huamán Cárdenas, Víctor Raúl
La sepsis es un síndrome clínico complejo asociado con alta mortalidad y desregulación de la coagulación, en el que los índices plaquetarios y el dímero D han sido propuestos como posibles biomarcadores de pronóstico. El objetivo del presente estudio fue determinar la relación que existe entre los índices plaquetarios y los niveles de dímero D en pacientes con sepsis. Se realizó un estudio cuantitativo, retrospectivo y transversal en una muestra de 83 pacientes hospitalizados con diagnóstico de sepsis entre enero y julio de 2024. Se analizaron el recuento plaquetario, el volumen plaquetario medio (VPM), la amplitud de distribución plaquetaria (PDW), el plaquetocrito (PCT) y los niveles de dímero D. Para el análisis de la asociación se utilizó la correlación de Spearman. Los resultados mostraron correlaciones muy fuertes y significativas (p < 0,001) entre los índices plaquetarios y el dímero D: recuento plaquetario (Rho = –0,865), VPM (Rho = 0,819), PDW (Rho = 0,818) y PCT (Rho = –0,816). Estos hallazgos evidencian que la disminución del número y masa plaquetaria, junto con la mayor heterogeneidad y tamaño de las plaquetas, se asocian a un incremento de la actividad trombótica reflejada en el dímero D. En conclusión, los índices plaquetarios, obtenidos de un hemograma rutinario, muestran una estrecha relación con el dímero D en pacientes con sepsis, lo que resalta su aplicabilidad clínica como predictores indirectos de la desregulación hemostática en esta condición.

(Universidad Privada Norbert Wiener, 2024-05-19) Fernández Julca, Heydi; Mori Castro, Jaime Alberto
Objective: "Analyze the relationship between work stress and quality of life among nursing professionals in the emergency department of a hospital in Lima, 2024." The study will follow a non-experimental design, applied type, quantitative approach, and correlational level. The sample will consist of 100 nurses. Two questionnaires will be used as instruments: The Nursing Stress Scale and the WHOQOL BREF quality of life scale, which will be administered through surveys. Both instruments have been validated using the KMO test, reporting indices of 0.932 and 0.76, with a significance level of 0.001 through Bartlett's sphericity test (p<0.001 and p<0.000). Reliability indices were reported using Cronbach's alpha: 0.98 for the first scale, and for the second instrument, quality of life reliability for each dimension was as follows: Physical 0.68; Psychological 0.69; Social 0.65; and Environment 0.69. Once all the data are collected, they will be analyzed using the statistical software SPSS v2.5 at both descriptive and inferential levels. For hypothesis testing, Spearman's Rho correlation coefficient will be used. All findings will be reported in figures and tables as appropriate. Additionally, the results will aim to address the study's stated objectives.
