La Revista Peruana de Ginecología y Obstetricia (RPGO) ha obtenido su inclusión en la importante base de datos Scopus. En una rápida recopilación de la publicación de la revista, se recuerda la dedicación editorial de sus seis editores, cuatro de los cuales acababan de presidir la Sociedad Peruana de Obstetricia y Ginecología (SPOG). Los momentos iniciales de trabajo editorial fueron realizados manualmente, en máquinas de escribir y visitando la imprenta continuamente, así como a los patrocinadores. El compromiso de los Comités Directivos de SPOG para financiar la publicación y distribución de los ejemplares permitió la gradual indexación a bases de datos locales, regionales e internacionales. Su internalización se amplió desde la publicación de la RPGO en el Open Journal Systems (OJS), sistema informático donde se publica los artículos con puntualidad, calidad, incluyendo sus características editoriales y la Información para los Autores. Ahora la publicación es solo virtual, en español e inglés, con visibilidad e impacto de los artículos desde el inicio de la RPGO en 1955. Con datos actualizados del OJS sobre la RPGO, el número de visitas mensuales a los resúmenes llegan hasta 10 mil y las descargas mensuales de artículos en formato PDF hasta más de 9 mil. Y, en el ámbito de revistas científicas de ginecoobstetricia de América Latina y España en Scopus, destaca el índice h de la RPGO por Google Scholar Metrics, como una de las mejores. Al presente, y frente a los desafíos futuros, la actividad de la RPGO ha sido fortalecida, estableciendo un equipo editorial y herramientas que permiten la ya iniciada profesionalización de los procesos de la actividad editorial.

The Peruvian Journal of Gynecology and Obstetrics (RPGO, for its acronym in Spanish) has obtained its inclusion in the important Scopus database. A quick review of the journal's publication recalls the editorial dedication of its six editors, four of whom had just recently chaired the Peruvian Society of Obstetrics and Gynecology (SPOG, for its acronym in Spanish). The initial editorial work was carried out manually, on typewriters and continuously visiting the printing press, as well as the sponsors. The commitment of the SPOG Steering Committees to finance the publication and distribution of the issues allowed the gradual indexing to local, regional and international databases. Its internalization was expanded since the publication of the RPGO in the Open Journal Systems (OJS), a computer system where articles are published with punctuality, quality, including their editorial characteristics and the Information for Authors. Now the publication is only virtual, in English and Spanish, with visibility and impact of the articles since the beginning of the RPGO in 1955. With updated OJS data on the RPGO, the number of monthly visits to the abstracts reaches up to 10 thousand and monthly downloads of articles in PDF format reach more than 9 thousand. And, in the field of obstetrics and gynecology scientific journals in Latin America and Spain in Scopus, the h index of the RPGO by Google Scholar Metrics stands out as one of the best. At present, and facing future challenges, the activity of the RPGO has been strengthened, establishing an editorial team and tools that allow the already initiated professionalization of the processes of the editorial activity.

Mecanismos de adaptação do coração em atletas de elite do sexo feminino: comparação com indivíduos sadios e tempo de treinamento / Heart adaptation mechanisms in elite female athletes: comparison with healthy individuals and time of training

Fundamento: O exercício intenso e continuado em atletas provoca fenótipos de remodelamento adaptativo, cujos parâmetros podem ser avaliados pela ecocardiografia convencional, e de deformação miocárdica. Assim, foi comparado o remodelamento miocárdico em atletas do sexo feminino (grupo atletas) com mulheres sedentárias da mesma faixa etária (grupo-controle) e entre atletas com maior e menor tempo de treinamento. Métodos: Foram selecionadas 57 futebolistas femininas (grupo atletas) e 25 mulheres sadias sedentárias (grupocontrole). As atletas foram divididas em dois grupos: grupo principal, com 32 atletas, e grupo sub-17, com 25 atletas. Foram determinadas, através de ecocardiografia, as dimensões, a função sistólica e diastólica das câmaras cardíacas e a deformação miocárdica (strain longitudinal, circunferencial, radial e mecânica rotacional), utilizando a estatística Z com significância de p < 0,05. Resultados: A idade dos grupos atletas, controle, principal e sub-17 foi de 22,1±6,3; 21,2±5,0; 26,5±5,1; e 16,5±0,6, respectivamente. O peso, o índice de massa corporal e a frequência cardíaca foram menores no grupo atletas. A espessura das paredes, o índice de massa do ventrículo esquerdo (VE), o volume do átrio esquerdo (AE), a fração de ejeção e as dimensões do ventrículo direito (VD) foram maiores no grupo atletas, mas dentro de valores normais. A deformação miocárdica mostrou diminuição do strain radial, da rotação basal, da rotação apical e do twist, sugerindo mecanismo de reserva contrátil. Esses parâmetros foram menores no grupo principal, que também apresentava maior espessura das paredes, maior volume do AE e maior tamanho do VD, sugerindo que o aumento da reserva contrátil se relaciona com maior tempo de treinamento. Conclusões: As atletas do sexo feminino com treinamento intenso de longa duração apresentam remodelamento adaptativo das câmaras cardíacas e aumento da reserva contrátil observada em repouso, com esses parâmetros mais acentuados nas atletas com maior tempo de treinamento.(AU)

Background: Intense continuous exercise provokes adaptive remodeling phenotypes in athletes, the parameters of which can be evaluated through conventional echocardiography and myocardial deformation. We compared myocardial remodeling in female athletes (athlete group) with sedentary women of the same age range (control group) and between older and younger athletes. Methods: A total of 57 female soccer players and 25 healthy sedentary women were selected. The athlete group was subdivided into a main group and those under 17 years of age (< 17 group). The dimensions and systolic and diastolic function of the cardiac chambers and myocardial deformation (longitudinal and circumferential, as well as radial strain and rotational mechanics) was determined through echocardiography, using the Z statistic with a significance level of p< 0.05. Results: The mean age of the athlete, control, main, and < 17 groups was 22.1 (SD, 6.3); 21.2 (SD, 5.0); 26.5 (SD, 5.1); 16.5 (SD, 0.6) years, respectively. Weight, body mass index and heart rate were lower in the athlete group. Wall thickness, left ventricular mass index, left atrial (LA) volume, ejection fraction, and right ventricular dimensions were higher in athlete group, but remained within normal ranges. Regarding myocardial deformation, there was decreased radial strain, basal rotation, apical rotation, and twisting in the athlete group, suggesting a contractile reserve mechanism. These parameters were lesser in the main athlete group, who also had greater wall thickness, greater volume in the left atrium (LA) and larger size in the right ventricle (RV), suggesting that increased contractile reserve is related to longer time spent in the sport. Conclusions: In female athletes who had undergone intense long-term training, we observed adaptive remodeling of the cardiac chambers and increased contractile reserve (at rest), and these changes were more pronounced in those with longer involvement in the sport.(AU)

Diagnostic utility of transcranial magnetic stimulation for neurodegenerative disease: a critical review / Utilidade diagnóstica da estimulação magnética transcraniana para doenças neurodegenerativas: uma revisão crítica

ABSTRACT. Neurodegenerative diseases pose significant challenges due to their impact on brain structure, function, and cognition. As life expectancy rises, the prevalence of these disorders is rapidly increasing, resulting in substantial personal, familial, and societal burdens. Efforts have been made to optimize the diagnostic and therapeutic processes, primarily focusing on clinical, cognitive, and imaging characterization. However, the emergence of non-invasive brain stimulation techniques, specifically transcranial magnetic stimulation (TMS), offers unique functional insights and diagnostic potential. TMS allows direct evaluation of brain function, providing valuable information inaccessible through other methods. This review aims to summarize the current and potential diagnostic utility of TMS in investigating neurodegenerative diseases, highlighting its relevance to the field of cognitive neuroscience. The findings presented herein contribute to the growing body of research focused on improving our understanding and management of these debilitating conditions, particularly in regions with limited resources and a pressing need for innovative approaches.

RESUMO. As doenças neurodegenerativas representam desafio significativo por seu impacto na estrutura cerebral, função e cognição. À medida que a expectativa de vida aumenta, a prevalência dessas doenças cresce rapidamente, resultando em substanciais encargos pessoais, familiares e sociais. Esforços têm sido feitos para otimizar os processos diagnósticos e terapêuticos, com foco principal na caracterização clínica, cognitiva e de imagem. No entanto, o surgimento de técnicas de estimulação cerebral não invasivas, especificamente a estimulação magnética transcraniana (EMT), oferece compreensão funcional e potencial diagnóstico únicos. A TMS permite a avaliação direta da função cerebral, fornecendo informações valiosas inacessíveis por outros métodos. Esta revisão teve como objetivo resumir a utilidade diagnóstica atual e potencial da EMT na investigação de doenças neurodegenerativas, destacando sua relevância para o campo da neurociência cognitiva. As conclusões aqui apresentadas contribuem para o crescente corpo de investigação centrado na melhoria da nossa compreensão e gestão dessas condições debilitantes, particularmente em regiões com recursos limitados e necessidade premente de abordagens inovadoras.

Introduction COVID- 19 is a disease that has claimed the lives of many people. However, alterations in labo-ratory profiles in the city of Tacna have not been accurately established in association with its severity to support diagnosis and treatment. Objective To determine biomarkers related to the severity of COVID- 19 in patients treated at the social security hospital in Tacna during 2020. Methods We performed an observational, cross- sectional, and analytical study that included 308 patients with COVID- 19 from the social security hospital in Tacna, Peru, during the "first wave" of the pandemic (from July to August 2020). Immunological, hematological, arterial gas, hemostasis, and biochemical markers were collected. Patients were categorized into mild, moderate, and severe based on the clinical criteria found on clinical records. Correlation strength was per-formed according to Spearman's Rho coefficient. The performance of the biomarkers associat-ed with severity was analyzed with the Receiver Operating Characteristic curve. Results Regarding hematological markers there was a positive correlation with monocyte count (correla-tion coefficient: 0.841; area under the curve 97.0%; p < 0.05) and a negative correlation with lymphocyte count (correlation coefficient: -0.622; area under the curve 82.7%; p < 0.05). Regarding biochemical markers, arterial gases and hemostasis, no significant correlations were found. In immunological markers, we found positive correlation with ferritin (correlation coef-ficient: 0.805; area under the curve 94.0%; p < 0.05), and C- reactive protein (correlation coeffi-cient: 0.587; area under the curve 87.4%; p < 0.05). Conclusions The biomarkers that can be considered as parameters associated with the severity of COVID- 19 are the absolute blood count of monocytes and serum ferritin concentration.

According to the percentage of lymphocytic infil-tration, 52% reported a rate of mild infiltration, 21% moderate, and 27% intense. At 72 months of follow-up, survival was 31% in G1, 48% in G2, and 77% in G3 (P= 0.001). Conclusion: The degree of intense lymphocytic infiltration in gastric cancer patients was associated with better survival at the 72-month follow-up.

Factores de riesgo de complicaciones perinatales en el embarazo de adolescentes / Risk factors for perinatal complications in adolescent pregnancy

Resumen OBJETIVO: Identificar los factores asociados que condicionan complicaciones perinatales en las adolescentes embarazadas. MATERIALES Y MÉTODOS: Estudio de serie de casos, retrospectivo, efectuado en adolescentes embarazadas atendidas en el Hospital General de la Zona 6, Ciudad Juárez, Chihuahua, entre marzo de 2020 y marzo de 2021. Se evaluaron las complicaciones perinatales que se clasificaron en: maternas durante el embarazo, trabajo de parto y puerperio. Y perinatales en el neonato. También se tomaron en cuenta los antecedentes obstétricos (embarazos, partos, cesáreas, abortos y complicaciones). Se utilizó la prueba de χ2 y en las variables estadísticamente significativas se llevó a cabo regresión logística. RESULTADOS: Se evaluaron 287 expedientes clínicos y se encontró asociación estadísticamente significativa entre las complicaciones perinatales y los embarazos sin control prenatal. El 49.8% de las adolescentes tuvieron complicaciones perinatales durante el embarazo, 24.4% en el trabajo de parto y el 0.3% en el puerperio, mientras que el 25.4% no experimentó complicaciones. CONCLUSIONES: Es evidente que la falta total o parcial de control prenatal, aunada al hecho de ser multigesta, soltera, consumir alcohol, vivir con los padres y encontrarse en la adolescencia temprana fueron factores de riesgo de complicaciones perinatales en el embarazo. En esta etapa de la vida el embarazo se asocia con diversos factores sociodemográficos que favorecen las complicaciones perinatales.

Abstract OBJECTIVE: To identify the associated factors that condition perinatal complications in pregnant adolescents. MATERIALS AND METHODS: Retrospective, case series study conducted in pregnant adolescents attended at the Hospital General de la Zona 6, Ciudad Juárez, Chihuahua, between March 2020 and March 2021. Perinatal complications were evaluated and classified as: maternal during pregnancy, labor and puerperium. And perinatal complications in the neonate. Obstetric history (pregnancies, deliveries, cesarean sections, abortions and complications) was also taken into account. The test of 2 was used and logistic regression was performed for statistically significant variables. RESULTS: A total of 287 clinical records were evaluated and a statistically significant association was found between perinatal complications and pregnancies without prenatal control. 49.8% of the adolescents had perinatal complications during pregnancy, 24.4% in labor, and 0.3% in the puerperium, while 25.4% experienced no complications. CONCLUSIONS: It is evident that the total or partial lack of prenatal control, together with the fact of being multigestational, single, consuming alcohol, living with parents and being in early adolescence were risk factors for perinatal complications in pregnancy. At this stage of life, pregnancy is associated with various sociodemographic factors that favor perinatal complications.

Tell me who your friends are?! The mediating role of friends' use in cannabis abuse

Abstract Objectives To evaluate the relationship between age at onset of cannabis use and cannabis abuse in a sample of Portuguese cannabis users, testing the mediating role of the number of friends using cannabis and comparing these relationships between male and female subsets. Method A sample of 529 Portuguese cannabis users comprising 276 males and 244 females aged from 14 to 21 years completed a sociodemographic questionnaire, the Cannabis Abuse Screening Test (CAST), and answered four questions related to cannabis use. Data were analyzed using the PROCESS macro in SPSS version 26.0. Results Age at onset of cannabis use was negatively related to the number of friends using cannabis, while the number of friends using cannabis had a positive relationship with cannabis abuse. As predicted, the number of friends using cannabis seems to have a mediating role in the relationship between cannabis onset age use and cannabis abuse, since the indirect effect was found to be significant. The pattern of the relationships among the variables observed was found to be similar for both male and female subsets of the sample. However, males reported higher cannabis abuse than females. Conclusion The results highlight the mediating role of friends' use of cannabis in the relationship between age at onset of cannabis use and users' abuse. These results highlight the importance of early intervention in cannabis use. In particular, the pattern of the relationships observed among the studied variables emphasizes the need to monitor and conduct peer training interventions or interventions to promote of social skills.

Electroencefalograma cuantitativo en la predicción precoz de la isquemia cerebral tardía en hemorragia subaracnoidea aneurismática: reporte de un caso / Quantitative electroencephalogram for prediction of delayed ischemia in subarachnoid haemorrhage: report of one case

Subarachnoid hemorrhage (SAH) is a devastating disease, with a mortality rate of 35%. Among patients who survive the initial bleeding, the leading cause of morbidity and mortality is delayed cerebral ischemia (DCI). Electroencephalography (EEG) can detect cerebral ischemia in the early stages. We report a 66-year-old female patient who consulted for ictal headache and impaired consciousness. On admission, she was confused, dysarthric, and with meningeal signs. Brain angio-CT showed SAH FISHER IV and an aneurysm of the left posterior cerebral artery. After excluding the aneurysm (by coiling), the patient recovered the altered consciousness. Continuous EEG monitoring was initiated. On the sixth day of follow up, she had a transient headache and apathy. The brain MRI showed low cerebral blood flow in the left frontotemporal area, without ischemic lesions. On the seventh day, she presented expression aphasia and right facial-brachial paresis. Angiography confirmed severe vasospasm in M1 and M2 segments bilaterally. Pharmacological angioplasty with nimodipine was performed, with an excellent radiological response, although not clinical. A second MRI was carried out on the eighth day, which showed a left insular infarction and generalized vasospasm. A second therapeutic angiography was performed; the patient persisted with aphasia and left central facial paresis. The quantitative EEG analysis performed retrospectively showed a generalized reduction in the spectral edge frequency 95 (SEF95; meaning slowing in the EEG signal) at the fourth day of follow up, three days earlier than the clinical and imaging diagnosis of DCI was established.

Encefalopatía subaguda en una paciente con policondritis recidivante: caso clínico / Subacute encephalopathy associated with relapsing polychondritis: report of one case

Relapsing polychondritis (RP) is a rare multisystemic autoimmune disorder characterized by the inflammation and destruction of cartilages, with preference for auricular, nasal and laryngotracheal cartilages. RP may also affect proteoglycan-rich structures, such as, blood vessels, eyes, kidneys, and heart. The central nervous system (CNS) is involved in less than 3% of patients. We report a 32-year-old female with RP associated with a progressive subacute encephalopathy characterized by behavioral disturbances, auditory and visual hallucinations. The EEG showed generalized slow activity and a mononuclear pleocytosis with increased protein was found in the cerebrospinal fluid. The brain magnetic resonance imaging showed multiple supra and infratentorial nodular inflammatory lesions. After initiating treatment with corticosteroids and cyclophosphamide, a significant improvement in chondritis and neurological status was observed.

Prehospital Care (PHC) is one of the fundamental pillars of Emergency Medical Systems that attempts to provide the best assistance, in the shortest time and at the lowest cost. For this purpose, it requires main components such as human resources and physical resources. Objective: To determine if the professional competencies of the personnel of the Ecuadorian Institute of Social Security (IESS) in the city of Guayaquil respond to the Prehospital Care Service in accordance with the legal hiring profiles. Materials and methods: The research has a quantitative approach, observational, prospective and cross-sectional design. The type of study is descriptive, since it allowed the collection of information and the individual or group measurement of the studied variable. The population of this study consisted of 32 professionals working as paramedics at the Ecuadorian Institute of Social Security in the city of Guayaquil. The results: Once the data were obtained, 56.3% of the professionals were female. With respect to the degree of the professionals registered in Senescyt, only 56.3% of them have incomplete degrees. For the professionals, 56.3% have the position of paramedic 1. 81.3% have the equivalent amount of work experience. In securing the scene, 46.9% meet the requirements. Pre-hospital care procedures at the IESS is one of the most important points in this study, since 65.6% of the patients were found to be partially compliant with these care procedures. Conclusion: In the review of competencies, we deduced that not all personnel were hired according to the hiring profile issued by the MDT. We could observe a clear difference between the hiring profiles between paramedic 1 to paramedic 5, which have different types of relevance, which shows that there is a lack of training at all levels(AU)

Prevalencia y Severidad de Caries Dental en los Niños Beneficiarios del Programa de Salud Oral Asociados a Escuelas de Chile

RESUMEN: La caries es la enfermedad crónica más prevalente en niños constituyendo un problema de salud pública a nivel mundial. El objetivo de este estudio fue determinar la prevalencia y severidad de caries en niños y niñas pertenecientes al Programa de Salud Oral asociado a escuelas de la Junta Nacional de Auxilio Escolar y Becas (JUNAEB). Se realizó un estudio de corte trasversal basado en datos del año 2015 del Sistema Informático del Programa de Salud Oral de JUNAEB. Las variables de estudio fueron presencia y severidad de caries (índices ceod y COPD) y las variables de asociación exploratorias fueron zona geográfica, provincias, sexo, tipo de dependencia administrativa del colegio, tipo de enseñanza, sistema de salud, situación de extrema pobreza, tipo de dentición y tipo de atención. La asociación independiente entre las variables se analizó mediante el test de Chi2 y t-test. La muestra quedó constituida por 162.116 individuos, siendo el 50 % mujeres. La población estudiada mostró una prevalencia de 49 % y un índice ceod y COPD de 2,48 y 1,55 respectivamente. La mayor prevalencia (63 %) fue la zona centro sur y la región del Bío-Bío mostró los mayores índices de severidad (p<0,001). Las asociaciones más significativas fueron entre caries y el nivel socioeconómico y zona geográfica (p<0,001). Este estudio evidencia la asociación de la prevalencia/ severidad de caries y el nivel socioeconómico, y la distribución geográfica de la caries; lo cual hace necesario implementar medidas preventivas que compensen la ruralidad o la falta de fluoración del agua en algunas zonas geográficas de pobreza extrema.

ABSTRACT: Caries is the most prevalent chronic disease in children, constituting a worldwide public health problem. The aim of this study was to determine the prevalence and severity of caries in children included in the Oral Health Program associated to schools of the National Board of School Aid and Scholarships (JUNAEB). A cross- sectional study based on data from 2015 electronic register JUNAEB Oral Health Program was carried out. The main variables studied were presence and severity of caries (dmft and DMFT indices) and association variables were geographical area, sex, type of administrative dependency of the school, type of education, health system, and situation of extreme poverty, type of teething and type of care. The independent association between the variables was analyzed using the Chi2 test and the t-test.The sample consisted of 162,116 individuals, 50 % being women. The studied population showed a prevalence of 49 % and a CEOD and COPD index of 2.48 and 1.55, respectively. The highest prevalence (63 %) was the south-central zone and the Bío- Bío region showed the highest severity indices (p <0.001). The most significant associations were between caries and socioeconomic level and geographic area (p <0.001). This study shows the association between caries prevalence / severity and socioeconomic level, and the geographical distribution of caries, which make necessary the implementation of preventive measures that compensate rurality, or the lack of water fluoridation in some areas of extreme poverty.
