Objetivo: Construir un modelo predictor para la conversión de pacientes sometidos a colecistectomía laparoscópica de emergencia. Material y Método: Analítico, observacional, retrospectivo de corte transversal en 203 historias de pacientes sometidos a colecistectomía laparoscópica de emergencia en el Hospital Víctor Lazarte Echegaray durante el periodo 2016-2017. Resultados: La frecuencia de conversión fue de 18.7% del total de pacientes. En el análisis bivariado, la edad (p=0.001; OR=10,56, IC95%=4,73-23,56), el sexo masculino (p=0.001; OR=10,98, IC95%=4,67-25,82), IMC (p=0,001; IC 95%= 1,23-3,10), leucocitos ≥18 000xmm3 (p=0,001 OR=5,95, IC95%=2,77-12.81) mostraron diferencia estadística significativa (p<0.05). En el análisis multivariado, la edad (p=0.000; OR=7,82, IC95%=2,60-23,48), el sexo masculino (p=0.000; OR=11,26, IC95%=3,58-35,33), IMC (P=0,001; OR=1,53, IC 95%= 1...

Background. The Peruvian population during Covid-19 has been exposed to stressful and traumatic events, associated with close experiences with suffering and death; but these experiences have also generated positive psychological growth. The objective was to develop a model of structural equations to determine if coping with stress is a predictor of post-traumatic growth in a Peruvian population. Method. The design was predictive cross-sectional. 310 people participated, 58 % men and 42 % women, aged 18 to 63 years (M=31.6). The COPE-28 Spanish version (Morán et al., 2010) and the Postraumatic Growth Inventory PTGI (Tedeschi & Calhoun, 1996), adapted by Ramos-Vera et al (2021). Results. In the first model, the coping strategies religion (β=.209, p<.01), self-distraction (β=.111, p<.01) and disconnection (β=-.147, p<.05) are significant predictors and explain 14.9 % of pos...

Objetivo: Determinar si la proteína c reactiva es un predictor de riesgo para la infección de sitio operatorio en pacientes apendicectomizados a cielo abierto del Hospital Belén de Trujillo. Material y métodos: Estudio analítico de cohorte histórica, en el cual se incluyó 188 historias clínicas de pacientes apendicectomizados a cielo abierto, de los cuales se dividieron en 2 grupos: 94 pacientes con proteína c reactiva elevada y 94 con proteína c reactiva normal al momento del ingreso por el servicio de emergencia. Las pruebas estadísticas fueron el riesgo relativo (RR) y la regresión logística. Resultados: Se evidenció que la proteína C reactiva se asocia de manera significativa (p=0.026) y muestra un valor predictivo positivo (RR=2.222) para infección en el sitio operatorio. La frecuencia de infección del sitio operatorio en apendicectomizados a cielo abierto fue de 15...

En este trabajo el autor considera una prueba de vida, de tipo 1I con censura, (terminología anglosajona) de N elementos cuyos tiempos de vida siguen una ley exponencial y construye un predictor bayesiano empírico del tiempo en que ocurrirá la r-ésima falla, habiendo observado la k-ésima, en la misma prueba. Además compara este predictor, con respecto a un predictor clásico y a un predictor bayesiano, a través de la simulación.

The present study has as aim the measure of the effect of the personality over the job satisfaction. There were assessed 65 workers (74.24% male and 25.75% female) from a transportation Enterprise located in Arequipa City, with two instruments: Job Satisfaction Questionnaire by Arias and Justo (2013) and Millon’s Inventory of Personality Styles (MIPS). The results indicate low and moderate levels of job satisfaction, so as high punctuations on the personality styles such as Openness, Modification, Individualism, Sensation, Reflection, Systematization, Righteous, Conformism and Control. Moreover, there were registered differences according to the sex, marital status, educational attainment, charge, work zone.

Objective: To determine the perinatal predictors of persistently low Apgar at 5 minutes in an EsSalud hospital. Material and methods: Observational, analytical case-control study. A census analysis of 889 neonates with low Apgar (<7) at the first minute treated at the Octavio Mongrut Muñoz Hospital from 2009-2018 was carried out, after verification of the inclusion and exclusion criteria. The EsSalud Perinatal Surveillance System (SVP) was used. The Chi square test and crude odds ratio (ORc) were used as a measure of association. Likewise, binary logistic regression was applied to estimate adjusted odds ratios (ORa). Results: There were 17,780 live births during the study period, of which 889 (11.9%) had low Apgar scores at one minute. The incidence of persistently low Apgar score at five minutes was 5.68 per 1,000 live births. In the multivariate analysis, the only perinatal predict...

The COVID-19 pandemic impacted the mental health of thousands of young people and adults, especially in its initial phase, since the disease was perceived as an uncertain and continuous threat, resulting in the fear of the coronavirus becoming dysfunctional, generating psychological discomfort. The principal aim of the study was to evaluate the psychosocial variables that predict fear of the coronavirus and its dimensions, in a sample of 384 Peruvian youth and adults, women (64.5%) and men (35.5%), between the ages of 18 and 67 (M= 26.36, SD=9.17). The predictor variables evaluated were Uncertainty, Stress, and the Use of the media, using for their measurement the IUS-12, the PSS-10 and the Scales of Use of the media and Fear of the coronavirus that belong to the Questionnaire of the Psychological Impact of the Coronavirus by Sandín et al. (2020). The results of the multiple linear regr...

Ante la capacidad predictiva de la teoría de la acción planificada en diversas gamas de conducta y la necesidad de explicar el rendimiento académico, no abordado hasta el momento por dicho modelo, se planteó como objetivos construir un instrumento que mida la acción planificada hacia el estudio, así como obtener sus evidencias de validez, y determinar si la acción planificada hacia el estudio predice el rendimiento académico en estudiantes de Psicología de una universidad particular de Trujillo. El estudio fue instrumental y ex post facto retrospectivo de grupo único. La muestra no probabilística de 153 participantes, respondió a la Escala de Acción Planificada para la Dedicación al Estudio (APDE), versión retrospectiva. Se obtuvo las evidencias de validez basadas en el contenido del instrumento (V=1; p<0.05); en su dimensionalidad (4 factores que explican el 66% de la var...

Objective: To evaluate the nutritional status as a predictor of mortality in elderly people with gastric cancer. Materials and methods: An observational, prospective and analytical study which included 47 patients over 60 years of age with a diagnosis of gastric cancer, referred to the geriatric department of the Hospital Nacional Guillermo Almenara from March 2014 to October 2015. The Body Mass Index (BMI) and the Mini Nutritional Assessment Short-Form (MNA-SF) were used to evaluate the patients. Results: Forty-seven (47) patients with a diagnosis of gastric cancer were included: 33 (70.2 %) were males, and the mean age was 75.52 (SD +/- 6.88) years for males and 77 (SD + / - 7.66) years for women. When performing the survival analysis, it was found that the nutritional assessment using the MNA-SF obtained statistical significance (p <0.05). Conclusions: In conclusion, A poor nutriti...
