In the last few years, many studies showed that to select cancer patients for a specific drug on the basis of specific genetic alterations could determine the greatest potential clinical benefit for a longer time, compared to treatment with the classic cytotoxic chemotherapy. Thus, oncology moves from the classic "one size fits all" approach, which provided classic chemotherapy agents on the basis of the cancer primary site and its histological type, to a new classification based on the tumor molecular profile. The characterization of the genetic alterations of the tumors, and the understanding of the complex interaction between the molecules of the same network represents, therefore, the rationale on which precision medicine is based. These advances have been made possible by the recent development of new technologies, such as next generation sequencing (NGS) or massive parallel sequencing (MPS), which allow the sequencing of larger gene portions compared to previous technologies, with reduced times and an increase in analytical sensitivity.</p> 2020-01-08T15:20:49+00:00 ##submission.copyrightStatement## http://revistas.urp.edu.pe/index.php/RFMH/article/view/2704 Presentation of the technical document: Analysis of the situation of Cancer in Peru 2018 2020-02-21T16:30:46+00:00 Willy Ramos jhony.delacruz@urp.edu.pe Jhony A. De La Cruz-Vargas jhony.delacruz@urp.edu.pe <p>The design and planning of prevention and control interventions as well as the evaluation of interventions already implemented require a situational analysis based on various systems and sources of information that allow directing and prioritizing resources to the most vulnerable and / or disadvantaged populations. Health situation analyzes constitute a powerful tool for the identification of needs and priorities, being essential for the construction of health policies. On December 27, 2019, the National Center for Epidemiology, Disease Prevention and Control presented in the Paraninfo of the Ministry of Health the "Analysis of the situation of cancer in Peru, 2018". This technical document seeks to contribute based on the analysis of data from various sources of information to the design of cancer prevention and control interventions in the country, particularly in the formulation of the National Plan for Comprehensive Cancer Care 2020-2024 which represents the continuation of the Hope Plan.</p> 2020-01-13T15:13:43+00:00 ##submission.copyrightStatement## http://revistas.urp.edu.pe/index.php/RFMH/article/view/2562 Perspectives for health technology assessment 2020-02-21T16:30:55+00:00 Marcus Tolentino Silva marcusts@gmail.com <p>An unplanned health care system is like a paper boat carried by a slowly sinking current. In times of disinformation and excessive distraction, investing in better facts on health technology assessment (HTA) will enable more active actions rather than reactive to the market dynamics. This paper aims to raise some reflections on HTA in terms of political context, health technologies and epidemiological priorities. The perspective of HTA is context dependent, intrinsic to its political and institutional articulation. At the moment, the paradox is to maintain a specialized structure in the face of economic austerity policies that reduce health resources, and a scenario of greater interest in raising public funds by the private sector. Particularly in Brazil, HTA will also have to deal with the gradual shift from a universal health system to a minimum portfolio of services offered by the private sector. The public sector will be requested for very expensive technologies, usually by judicial measures. The precariousness of work relationships will influence HTA workers because they will not have a link and identity with the health system. Thus, there will be more productive and less reflective HTA processes. The context of greater dependence on the private market will allow new problems with medical technologies to emerge, such as the opioid crisis in the United States.</p> 2019-12-26T15:45:00+00:00 ##submission.copyrightStatement## http://revistas.urp.edu.pe/index.php/RFMH/article/view/2543 Severity prognostic factors in patients with acute pancreatitis in Hospital Nacional Sergio E.

The management of the cadre by health personnel presents a high variability due to factors that are currently unknown. There is no standard of reference or a clinical prediction model that can guide our decisions when approaching a spider bite patient. Objective: Develop and validate a clinical prediction rule for systemic loxoscelism. Methods: An observational study of derivation and validation of a clinical prediction model was carried out with diagnostic test validation based on a historical single-arm cohort in patients treated at Vitarte Hospital between 2007 and 2016 and international clinical reports published. Results: Systemic loxoscelism occurred only in 32.9% (n = 24) of cases. For the bivariate analysis, the variables that showed a statistically significant association (P &amp;lt;0.05) were sex, bite in an independent abdomen in relation to other parts of the body, bite in other parts of the body than the abdomen, vomiting , fever and hemoglobinuria. The regression analysis included in the analysis the variables: sex, vomit, fever and hemoglobinuria. Bootstrapping determined the internal validity of the model. The area under the curve was 0.91 (P &amp;lt;0.05) and the sensitivity, specificity, LR + and LR- were 79.1%, 93.8%, 12.9 and 0.22 respectively. Conclusions: The protocol of prediction of systemic derived loxoscelism is valid, for the moment.</p> 2020-01-08T15:19:15+00:00 ##submission.copyrightStatement## http://revistas.urp.edu.pe/index.php/RFMH/article/view/2546 Learning and academic performance styles in nursing internships of a peruvian public university 2020-02-21T16:32:08+00:00 Ana Maria Chambi-Choque jhony.delacruz@urp.edu.pe Jorge Manrique-Cienfuegos jhony.delacruz@urp.edu.pe Tula Margarita Espinoza-Moreno jhony.delacruz@urp.edu.pe <p>Objective: To evaluate the learning style (EEAA) and its relation with the academic performance (RA), in Nursing Interns of a national university of Peru.

Objective: To evaluate the efficacy, safety and adverse events caused by the application of 755 nm Alexandrite laser for the treatment of Ota nevus. Methods: Case series of 10 phototype IV patients with unilateral Ota Nevus treated between January 2017 and December 2018, which were treated with this light energy and with defined parameters. Results: The mean age was 29 years. The patients who completed the treatment did not show repigmentation in the treated lesion and the satisfaction index was acceptable. It was observed that the average of sessions to obtain favorable results varied between 8 and 10 applications. Among the most important adverse effects, post-inflammatory hyperpigmentation and the removal of the superficial layer of the post laser skin stand out. All were controlled without leaving permanent residual lesions. Conclusion: The 755 nm Alexandrite Q-switched laser is an effective technology to achieve a high degree of depigmentation in the treatment of Ota nevus and can be considered as a first-line treatment for the management of this pathology.</p> 2019-12-26T14:31:06+00:00 ##submission.copyrightStatement## http://revistas.urp.edu.pe/index.php/RFMH/article/view/2552 Anti-inflammatory activity of the ethnolic extract of the leaves of manihot esculenta Crantz (yuca) in an experimental model of acute inflammation 2020-02-21T16:32:22+00:00 Nathalie D.

Carrageenan was used as an inflammatory inducer that was administered intradermally; for the measurement of plantar edema, the Digital Water Plethysmometer (LE7500) was used. Tween 80 / water solution (1:10) was administered to the negative control group at a dose of 1mL./100g., To the betamethasone positive control group 4mg / Kg and to treatment groups 1 and 2 Manihot esculenta Crantz, 2 mg / kg and 4 mg / kg, respectively. The 1-tail ANOVA test and the Tukey post hoc test were used for comparisons between the groups. Results: In 37.67% of treatment group 2 a reduction in edema was observed 3 hours after administering Manihot esculenta Crantz (p &lt;0.05). In both administration groups of Manihot esculenta Crantz there was a nonsignificant trend to reduce plantar edema with values close to significance. Conclusion: The Manihot esculenta Crantz ethanolic extract at a 4 mg / kg dose probably have anti-inflammatory activity in this animal model of acute inflamation.</p> 2019-12-26T14:30:48+00:00 ##submission.copyrightStatement## http://revistas.urp.edu.pe/index.php/RFMH/article/view/2553 The measurement of inequality in the reduction of child mortality in Peru 2020-02-21T16:32:24+00:00 Ramón Figueroa Mujica guichiyt@hotmail.com Guisela Yábar Torres jhony.delacruz@urp.edu.pe Krupuskaya Figueroa Yabar jhony.delacruz@urp.edu.pe <p>Objective: To define the feasibility of determining inequality in infant mortality according to the mother's educational level and according to the wealth quintile of the 1991-2013 period, considering the level of precision of said rates. Methods: The type of study was quantitative and observational, with a crosssectional design based on repeated surveys. The data from the ENDES surveys corresponding to those of 1991, 1992, 1996, 2000, 2008 and 2013 were used. Infant mortality was determined using the direct method of synthetic cohort life tables. The level of precision of the estimates was determined by the relative error. Results: It´s observed that the level of precision of the estimates of these general rates has fluctuated between good and very good in the 1991-1992, 1996 and 2000 surveys; however, in 2008 and 2013 they only reach an acceptable level. Infant mortality rates tend to be lower as the mother's educational level improves, as well as the wealth quintile and elsewhere exists among successive surveys a tendency to reduce infant mortality in different categories. Conclusion: It is not feasible to determine the inequality of the measurement of Infant Mortality according to the mother's educational level and according to the wealth quintile in the period 1991-2013, because the sample size has not been increased, depending on the decreased mortality.</p> 2019-12-26T14:30:36+00:00 ##submission.copyrightStatement## http://revistas.urp.edu.pe/index.php/RFMH/article/view/2561 Advancing sustainable development goals through public health service learning 2020-02-21T16:30:57+00:00 Miguel A.

Methods: Pilot study, ecological from secondary sources. Modifiable risk factors, exposure prevalence, relative risks of these factors (RR) or an approximation by means of possibilities ratio (OR) were searched and selected. The information was recorded in a data collection form which was validated by expert judgment. For the calculation of the Population Attributable Fraction (FAP), the formula proposed by Parkin was tested and a statistical simulation model was developed with R. Studio V. 3.6.1 software. Results: In Peru there are prevalence studies for the majority of modifiable risk factors; Likewise, studies with OR estimates for several of the factors are available in Latin America; however, studies from the United States had to be used for the remaining factors. No national studies of ionizing or ultraviolet radiation were found. The syntax of the statistical simulation model was tested, which proved to be valid and consistent with the results of international FAP studies within the ranges of published studies. Conclusion: It is feasible and viable to carry out PAF studies of modifiable risk factors for cancer in Latin American countries, particularly in Peru, where the information required for its estimation is available.</p> 2020-01-28T01:07:30+00:00 ##submission.copyrightStatement## http://revistas.urp.edu.pe/index.php/RFMH/article/view/2660 Prevalence and factors associated with the low consumption of fruits and vegetables in students of the professional career of human medicine of a peruvian university 2020-02-21T16:30:49+00:00 Alan Huamancayo-Espíritu jhony.delacruz@urp.edu.pe Luis Pérez-Cárdenas alan.smill7@gmail.com <p><strong>Objective</strong>: To determine the prevalence and factors associated with the low consumption of fruits and vegetables in students of the professional career of human medicine of the National University Hermilio Valdizán (UNHEVAL). <strong>Methods</strong>: Cross-sectional study. The population was constituted by 371 students of the professional career of Human Medicine who were enrolled and taking courses in July 2018. It was applied a self-administered questionnaire which allowed to obtain information about the consumption of fruits and vegetables. From the collected data it was obtained the prevalence and factors associated with low consumption of fruits and vegetables. <strong>Results</strong>: The prevalence of low consumption of fruits and vegetables was 60,1% (IC95%: 55,0% -65,2%). The main reasons for not consuming fruits and vegetables were that it is rare to get them in the cafeterias of the university (78,7%), insufficient time for their selection, purchase and preparation (73,6%) and living with one of the parents who were in charge for their feeding. (55,3%). The multivariate analysis found that the only factor associated with low consumption of fruits and vegetables was the insufficient time for selection, purchase and preparation; whereas, living with one of the parents constituted a factor protector. <strong>Conclusion</strong>: There is a high prevalence of low consumption of fruits and vegetables in students of the professional career of human medicine of the UNHEVAL. The insufficient time for the selection, purchase and preparation of fruits and vegetables is an associated factor and living with one of the parents constitutes a protector factor.</p> 2020-01-09T18:29:50+00:00 ##submission.copyrightStatement## http://revistas.urp.edu.pe/index.php/RFMH/article/view/2280 Radiological semiology in emergency brain pathology 2020-02-21T16:32:34+00:00 Alexander Humberto Román Meza alexrom2490@gmail.com Celso Huamán-Correa jhony.delacruz@urp.edu.pe <p>Radiology is a great tool in the diagnosis of encephalic pathologies, especially in situations of neurological urgency and emergency, to rule out the presence of a specific pathology, and to definite the location and size of the lesion, or clarify an initial uncertain diagnosis.

Fernandez-Sandoval majus_1996@hotmail.com Bryam J. Vasquez-Zavala jhony.delacruz@urp.edu.pe <p>Introduction: Traffic accidents (AT) are the first priority in health research in Peru, According to the World Health Organization (WHO) it is estimated that the economic costs of vehicle impact and injuries due to AT are 1 % and 1.5% of the Gross National Product (GNP) in low and middle income countries; In Peru it is approximately 1.5 - 2% of the Gross Domestic Product (GDP). Objective: To determine if there is an association between the time of prehospital care and hospital mortality in victims of traffic accidents. Methods: A systematic review was carried out through the literature search of related articles in indexing sources such as PubMed and BIREME. Results: Delays in the transfer of patients to the hospital and the lack of pre-hospital Emergency Medical System (SME) were significantly associated with an increase in mortality (P: 0.000) and the need for an SME as a prehospital care provider was significant predictor of emergency mortality with an adjusted odds ratio [OR] 2.19; 95% CI [1.88–2.55], and in the first 24 hours of admission with an adjusted OR 2.31; 95% CI [1.95–2.73]. Conclusion: The time of pre-hospital care in traffic accidents is significantly associated with hospital mortality, therefore, it is proposed to study factors associated with the longtime of pre-hospital care.</p> 2019-12-26T14:29:29+00:00 ##submission.copyrightStatement## http://revistas.urp.edu.pe/index.php/RFMH/article/view/2556 Xp11.2 translocation renal carcinoma in a child 2020-02-21T16:32:30+00:00 Gloria Paredes-Guerra gloriaparedes2000@yahoo.com Javier Larios-León jhony.delacruz@urp.edu.pe Carol Gonzales-Gonzales jhony.delacruz@urp.edu.pe <p>Translocation renal cell carcinoma (t-RCC) is a subtype of renal cell carcinoma (RCC).
