Importancia cultural de la flora empleada por la comunidad nativa Asheninka Sheremashe, Ucayali, Perú / Cultural importance of the flora used by the Asheninka Sheremashe native community, Ucayali, Peru

The cultural significance of the flora used by the native Asheninka Sheremashe community in Ucayali, Peru was determined. To do this, a fieldwork of over 4 months was conducted, involving semi-structured interviews with 106 residents through non-probabilistic convenience sampling. The community utilizes 139 plant species in their daily lives, belonging to 120 genera and 52 families, with the most abundant being Fabaceae, Arecaceae, Malvaceae, Solanaceae, Poaceae, and Rutaceae. Furthermore, 25.9% of the species are of significant importance to theinhabitants according to the Cultural Index (CI), such as Manihot esculenta, Theobroma cacao, Bixa orellana, Musa paradisiaca, Ficus insipida, among others. It can be concluded that the flora plays a prominent role in the life of the community, with the categories reporting the highest number of species being: food (29.35%), medicine (28.36%), culture (9.95%), construction (9.45%), lumber (6.97%), commerce (3.48%), craftsmanship (2.49%), toxic (2.49%), and other uses (7.46%)

Proportion of cancer cases and deaths attributable to potentially modifiable risk factors in Peru.

BACKGROUND: Limited evidence exists on the population attributable fraction (PAF) of cancer cases and deaths in Latin America. In Peru several studies have been published regarding the PAF of various risk factors and their associated diseases. The objective of this study was to estimate the fraction of cancer cases and deaths attributable to potentially modifiable risk factors in Peru in 2018, before the COVID-19 pandemic in the population of 15 years old and older. METHODS: An ecological study was conducted using the prevalence of exposure of the Peruvian population to modifiable risk factors for cancer, the relative risk associated with each factor, and the number of cancer cases and deaths in 2018 as inputs. We used the Parkin formula with a Montecarlo statistical simulation model to calculate the PAF and confidence intervals. The number of new cancer cases and deaths attributed to each risk factor was determined by multiplying the number of cases and deaths in each gender by the PAF of each risk factor. FINDINGS: In Peru, 38.5% of new cases (34.5% in men and 42% in women) and 43.4% of cancer-related deaths (43.4% in men and 43.4% in women) were attributable to modifiable risk factors. The number of cancers attributable was 25,308 (10,439 in men and 14,869 in women) and the number of deaths attributable to cancer was 14,839 (6,953 in men and 7,886 in women). The predominant modifiable risk factors contributing to the highest number of cases and deaths were HPV infection (4,563 cases, 2,409 deaths), current tobacco use (3,348 cases, 2,180 deaths), and helicobacter pylori infection (2,677 cases, 1,873 deaths). Among the risk factors, oncogenic infections constituted the group with the highest PAF (16.6% for cases, 19.2% for deaths) followed by other unhealthy lifestyle factors (14.2% for cases, 16.7% for deaths), tobacco (7.2% for cases, 7.2% for deaths) and ultraviolet radiation (0.5% for cases, 0.3% for deaths). CONCLUSIONS: Prior to the COVID-19 pandemic, 38.5% of cancer cases and 43.4% of cancer-related deaths in Peru were linked to modifiable risk factors in the population of 15 years old and older. Most preventable cancer cases and deaths were related to oncogenic infections, primarily caused by HPV and helicobacter pylori, followed by tobacco and obesity.

Implementation of new technologies designed to improve cervical cancer screening and completion of care in low-resource settings: a case study from the Proyecto Precancer.

BACKGROUND: This case study details the experience of the Proyecto Precancer in applying the Integrative Systems Praxis for Implementation Research (INSPIRE) methodology to guide the co-development, planning, implementation, adoption, and sustainment of new technologies and screening practices in a cervical cancer screening and management (CCSM) program in the Peruvian Amazon. We briefly describe the theoretical grounding of the INSPIRE framework, the phases of the INSPIRE process, the activities within each phase, and the RE-AIM outcomes used to evaluate program outcomes. METHODS: Proyecto Precancer iteratively engaged over 90 stakeholders in the Micro Red Iquitos Sur (MRIS) health network in the Amazonian region of Loreto, Perú, through the INSPIRE phases. INSPIRE is an integrative research methodology grounded in systems thinking, participatory action research, and implementation science frameworks such as the Consolidated Framework for Implementation Research. An interrupted time-series design with a mixed-methods RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) evaluation framework was used to examine the adoption of human papillomavirus (HPV) testing (including self-sampling), with direct treatment after visual inspection with portable thermal ablation, at the primary level. RESULTS: This approach, blending participatory action research, implementation science, and systems-thinking, led to rapid adoption and successful implementation of the new cervical cancer screening and management program within 6 months, using an HPV-based screen-and-treat strategy across 17 health facilities in one of the largest public health networks of the Peruvian Amazon. Monitoring and evaluation data revealed that, within 6 months, the MRIS had surpassed their monthly screening goals, tripling their original screening rate, with approximately 70% of HPV-positive women reaching a completion of care endpoint, compared with around 30% prior to the new CCSM strategy. CONCLUSIONS: Proyecto Precancer facilitated the adoption and sustainment of HPV testing with subsequent treatment of HPV-positive women (after visual inspection) using portable thermal ablation at the primary level. This was accompanied by the de-implementation of existing visual inspection-based screening strategies and colposcopy for routine precancer triage at the hospital level. This case study highlights how implementation science approaches were used to guide the sustained adoption of a new screen-and-treat strategy in the Peruvian Amazon, while facilitating de-implementation of older screening practices.

Case series of complicated bronchopulmonary lophomoniasis. Differential diagnosis of tuberculosis?

Pulmonary lophomoniasis is a rare and life-threatening disease, most commonly reported across Asian and Latin American countries. Here, we have reported two cases of pulmonary lophomoniasis presenting with atypical manifestations. Case #1 represents a 19-year-old male patient with clinical characteristics suggestive of tuberculosis, presenting with hemoptysis and receiving antituberculosis treatment. Case #2 represents a 69-year-old man with post-tuberculosis pulmonary disease with cystic bronchiectasis presenting with polymicrobial co-infection. Based on our case experience, lophomoniasis should be considered in patients with pneumonia who do not respond to antibiotic treatment, and the corresponding epidemiological factors should be carefully considered in addition to bronchoscopy for precise diagnosis.

Therapeutic Potential of Cannabinoid Profiles Identified in Cannabis L. Crops in Peru.

Cannabis is a plant that is cultivated worldwide, and its use is internationally regulated, but some countries have been regulating its medicinal, social, and industrial uses. This plant must have arrived in Peru during the Spanish conquest and remains widely cultivated illicitly or informally to this day. However, new regulations are currently being proposed to allow its legal commercialization for medicinal purposes. Cannabis contains specific metabolites known as cannabinoids, some of which have clinically demonstrated therapeutic effects. It is now possible to quantitatively measure the presence of these cannabinoids in dried inflorescences, thus allowing for description of the chemical profile or "chemotype" of cannabinoids in each sample. This study analyzed the chemotypes of eight samples of dried inflorescences from cannabis cultivars in four different regions of Peru, and based on the significant variation in the cannabinoid profiles, we suggest their therapeutic potential. The most important medical areas in which they could be used include the following: they can help manage chronic pain, they have antiemetic, anti-inflammatory, and antipruritic properties, are beneficial in treating duodenal ulcers, can be used in bronchodilators, in muscle relaxants, and in treating refractory epilepsy, have anxiolytic properties, reduce sebum, are effective on Methicillin-resistant Staphylococcus aureus, are proapoptotic in breast cancer, can be used to treat addiction and psychosis, and are effective on MRSA, in controlling psoriasis, and in treating glioblastoma, according to the properties of their concentrations of cannabidiol, cannabigerol, and Δ9-tetrahydrocannabinol, as reviewed in the literature. On the other hand, having obtained concentrations of THC, we were able to suggest the psychotropic capacity of said samples, one of which even fits within the legal category of "non-psychoactive cannabis" according to Peruvian regulations.

Understanding the pathogenic mechanisms and therapeutic effects in neurocysticercosis.

Despite being a leading cause of acquired seizures in endemic regions, the pathological mechanisms of neurocysticercosis are still poorly understood. This study aims to investigate the impact of anthelmintic treatment on neuropathological features in a rat model of neurocysticercosis. Rats were intracranially infected with Taenia solium oncospheres and treated with albendazole + praziquantel (ABZ), oxfendazole + praziquantel (OXF), or untreated placebo (UT) for 7 days. Following the last dose of treatment, brain tissues were evaluated at 24 h and 2 months. We performed neuropathological assessment for cyst damage, perilesional brain inflammation, presence of axonal spheroids, and spongy changes. Both treatments showed comparable efficacy in cyst damage and inflammation. The presence of spongy change correlated with spheroids counts and were not affected by anthelmintic treatment. Compared to white matter, gray matter showed greater spongy change (91.7% vs. 21.4%, p < 0.0001), higher spheroids count (45.2 vs. 0.2, p = 0.0001), and increased inflammation (72.0% vs. 21.4%, p = 0.003). In this rat model, anthelmintic treatment destroyed brain parasitic cysts at the cost of local inflammation similar to what is described in human neurocysticercosis. Axonal spheroids and spongy changes as markers of damage were topographically correlated, and not affected by anthelmintic treatment.

Influence of the geographic location and house characteristics on the concentration of microplastics in indoor dust.

Microplastics (MPs) are known for their ubiquity, having been detected in virtually any environmental compartment. However, indoor MPs concentrations are poorly studied despite being closely related to human exposure. The present study aims to evaluate the presence of MPs in settled atmospheric dust in 60 houses distributed in 12 districts of the metropolitan city of Lima, Peru, and investigate the influence of their geographical location and house characteristics. MPs concentration ranged from 0.01 to 33.9 MPs per mg of dust. Fibers and blue were the most frequent shape and color (98 % and 69 %, respectively). Also, 82 % of the particles were between 500 µm - 5 mm in size. A higher concentration of MPs was identified in the center-south of the city. The houses located on the highest floors (levels 4 to 13 to ground) displayed higher concentrations. MPs were primarily composed of polyester (PET), polypropylene (PP), and ethylene-vinyl acetate (EVA), among others. The polymers identified suggest that MPs derived from the fragmentation of components frequently found in houses, such as synthetic clothing, food storage containers, toys, carpets, floors, and curtains. The incorporation of MPs from the outside into dwellings is not ruled out. Future studies should evaluate the influence of consumption habits and housing characteristics on the abundance of MPs.

Measuring Socioeconomic Inequalities in HIV Testing During Antenatal Care: A Peruvian National Survey.

Although several Latin American countries have 70% antenatal care coverage, the proportion of human immunodeficiency virus (HIV) testing of Peruvian pregnant women and the socioeconomic inequalities of this preventive measure are unknown. This study aimed to determine socioeconomic inequalities and quantify the contribution of contextual and compositional factors on HIV testing during prenatal care in Peru. A cross-sectional study of the 2021 Demographic and Family Health Survey data was conducted. The outcome variable was HIV testing of pregnant women during prenatal care. An analysis of inequalities was performed including the determination of concentration curves and a decomposition analysis of concentration indices. Of a total of 17521 women aged 15 to 49 years, 91.4% had been tested for HIV during prenatal care. The concentration curves showed that prenatal HIV testing was concentrated among richer women, while the decomposition analysis determined that the main contributors to inequality were having a higher education, residing in an urban area, and in the highlands, belonging to the wealthy quintile, and being exposed to television and newspapers. Strategies focused on improving access, promotion and restructuring of prevention of mother-to-child transmission measures should be prioritized.

Short-, mid-, and long-term complications after multisystem inflammatory syndrome in children over a 24-month follow-up period in a hospital in Lima-Peru, 2020-2022.

Objective: To determine the short-, mid-, and long-term complications after multisystem inflammatory syndrome in children (MIS-C) over a 24-month follow-up period in a hospital in Lima, Peru, 2020-2022, and to explore differences according to the immunomodulatory treatment received and type of SARS-CoV-2 virus circulating. Methods: Ambispective 24-month follow-up study in children <14 years of age diagnosed with MIS-C at the Hospital Nacional Edgardo Rebagliati Martins (HNERM). Results: A total of 62 children were admitted with MIS-C. The most common short-term complications and serious events were intensive care unit (ICU) admission, invasive mechanical ventilation (IMV) due to respiratory failure, and shock; predominantly during the second pandemic wave (lambda predominance) and in children that received intravenous immunoglobulin (IVIG) plus a corticosteroid. Two patients died during the first wave due to MIS-C. During prospective follow-up (median of 24 months; IQR: 16.7-24), only 46.7% of patients were followed for >18-24 months. Of the total, seven (11.3%) patients were identified with some sequelae on discharge. Among the 43 remaining children, sequelae persisted in five (11.6%) cases (neurological, hematological, and skin problems). Six patients (13.9%) presented with new onset disease (hematologic, respiratory, neurological, and psychiatric disorders). One patient died due to acute leukemia during the follow-up period. None of them were admitted to the ICU or presented with MIS-C reactivation. Two patients presented persistence of coronary aneurysm until 8- and 24-month post-discharge. Conclusion: In our hospital, children with MIS-C frequently developed short-term complications and serious events during the acute phase, with less frequent complications in the mid- and long-term. More studies are required to confirm these findings.

Impact of oral onditions on Quality of Life in Peruvian Preschoolers in Rural and Urban Areas / Impacto de las alteraciones bucales en la calidad de vida de preescolares peruanos de zonas rurales y urbanas

Abstract The objective of this study is to determine the impact of oral conditions on the quality of life related to the oral health of preschool children in a rural and urban area of Cusco. The study was descriptive and cross-sectional, from a population of 179 preschoolers aged 3 to 5 years, from two public early childhood education institutions, and their respective parents or caregivers in the department of Cusco, Peru. We worked with the entire population that met the inclusion and exclusion criteria, seventy-four preschool children were selected for each area, deciding to have the same amount of children per group based on the smallest group. A clinical odonto-stomatological examination was carried out for oral conditions (dental caries, malocclusion, and dental trauma) according to the WHO's criteria and a survey that was used for sociodemographic characteristics. In addition, a validated Peruvian version of the ECOHIS questionnaire was used to obtain data on the impact on quality of life. All the variables of the total and individual scores of the ECOHIS domains were analyzed individually and the Kruskal-Wallis test was used to determine the association between variables. The oral conditions prevalence in preschool children in rural areas referring to dental caries was 100% (dmft index > 6), dental trauma 10.8%, and malocclusions 60.8%; for the urban area dental caries was 93.2% (dmft index > 6), dental trauma 9.5% and malocclusions 36.5%. Of the three oral conditions only the experience of dental caries was related to the OHRQOL of preschoolers in urban and rural areas.

Resumen El objetivo de este estudio es determinar el impacto de las alteraciones bucales en la calidad de vida relacionada con la salud bucal de niños preescolares de una zona rural y urbana de Cusco. El estudio fue descriptivo y transversal, de una población de 179 preescolares de 3 a 5 años de edad, de dos instituciones públicas de educación inicial, y sus respectivos padres o cuidadores en el departamento de Cusco, Perú. Se trabajó con toda la población que cumplió con los criterios de inclusión y exclusión, se seleccionaron setenta y cuatro niños preescolares por cada área, decidiendo tener la misma cantidad de niños por grupo en base al grupo más pequeño. Se realizó un examen clínico odonto-estomatológico para detectar alteraciones bucales (caries dental, maloclusión y trauma dental) según los criterios de la OMS y una encuesta que se utilizó para las características sociodemográficas. Además, se utilizó una versión peruana validada del cuestionario ECOHIS para obtener datos sobre el impacto en la calidad de vida. Todas las variables de los puntajes totales e individuales de los dominios ECOHIS fueron analizadas individualmente y se utilizó la prueba de Kruskal-Wallis para determinar la asociación entre variables. La prevalencia de alteraciones bucales en niños preescolares de zonas rurales referida a caries dental fue del 100% (índice dmft > 6), traumatismo dental 10,8% y maloclusiones 60,8%; para la zona urbana la caries dental fue del 93,2% (índice dmft > 6), el traumatismo dental 9,5% y las maloclusiones 36,5%. De las tres alteraciones bucales, sólo la experiencia de caries dental se relacionó con la OHRQOL de los preescolares de las zonas urbana y rural.

Rechazo de donantes de sangre en un hospital peruano durante la pandemia de la covid-19 / Rejection of blood donors in a Peruvian hospital during the COVID-19 pandemic i: en

Introducción: El SARS-CoV-2 ha tenido un impacto negativo y significativo en los sistemas de salud a nivel mundial, lo cual además amenazó el suministro de sangre necesario para las transfusiones clínicas. Objetivo: Describir las causas del rechazo de donantes de sangre durante la pandemia de covid-19. Métodos: Se realizó un estudio observacional, transversal y retrospectivo en una población de donantes que acudió al Banco de Sangre del Hospital Nacional Ramiro Prialé Prialé, de Huancayo, en Perú, de julio del 2020 a igual mes del 2022. Las variables analizadas fueron sexo, grupo sanguíneo ABO, factor Rh y tipos y causas de rechazo. Resultados: Del total de 10 177 donantes de sangre, fueron diferidos y excluidos 3390 (33,3 %); la causa más frecuente de diferimiento fue el hematocrito bajo (18,0 %) y la de exclusión, la positividad por el anticuerpo del núcleo de la hepatitis B (36,8 %). Asimismo, predominó el sexo masculino entre los que fueron rechazados (55,2 %) y se evidenció un incremento de la tendencia politómica en los donantes diferidos (R²=0,2214) y excluidos (R²=0,1178). Conclusiones: La prevalencia de diferimiento y exclusión de donantes de sangre hallada en esta serie fue relativamente alta en comparación con la registrada en otros estudios, lo cual se debió principalmente, en cada caso respectivo, al hematocrito bajo y a la presencia del anticuerpo del núcleo de la hepatitis B.

Introduction: SARS-CoV-2 has had a negative and significant impact on global health systems, threatening the necessary blood supply for clinical transfusions. Objective: To describe the causes of rejection of blood donors during the COVID-19 pandemic. Methods: An observational, cross-sectional and retrospective study was carried out in a population of donors who attended the Blood Bank of Ramiro Prialé Prialé National Hospital, in Huancayo, Peru, from July, 2020 to the same month, 2022. The analyzed variables were sex, the ABO blood group, Rh factor and types and causes of rejection. Results: Of total of 10 177 blood donors, 3390 (33.3%) were differed and excluded; the most frequent cause of differing was the low hematocrit (18.0%) and the most frequent cause of exclusion was antibody to hepatitis B core antigen positivity (36.8%). Likewise, male sex predominated among those who were rejected (55.2%) and an increment of the polytomous tendency was evidenced in differed (R²=0.2214) and excluded donors (R²=0.1178). Conclusions: The prevalence of differing and exclusion in blood donors was relatively high compared to that reported in other studies, which was mainly due, in each respective case, to the low hematocrit and the presence of antibody to hepatitis B core antigen.

Resistencia a los azoles en cepas de Aspergilus fumigatus sensu stricto aislados de muestras clínicas respiratorias

Introducción. La aspergilosis invasiva presenta alta mortalidad en pacientes con enfermedades crónicas e inmunocomprometidos. Aspergillus fumigatus sensu stricto (AFSS) es el principal agente etiológico y su tipificación requiere de métodos moleculares. La incidencia incrementada de AI resistentes a los antifúngicos demanda un diagnóstico certero y oportuno. Métodos. Se estudiaron 20 cepas de la micoteca del Instituto de Medicina Tropical - Universidad Nacional Mayor de San Marcos, aisladas de muestras respiratorias e identificadas como Aspergillus fumigatus sensu lato mediante el estudio macroscópico y microscópico. Las cepas fueron referidas a la Universidad Nacional del Litoral para su tipificación mediante una PCR screening para AFSS basada en secuencias del gen CYP51A y el estudio de sensibilidad antifúngica para voriconazol (VOR), itraconazol (ITC), posaconazol (POS), isavuconazol (ISA), anidulafungina (ANF), caspofungina (CSF) y anfotericina B (AMB) obteniendo la concentración inhibitoria mínima (CIM) mediante el protocolo de CLSI M38M51S-Ed3. Resultados. Las 20 cepas fueron identificadas como AFSS. Ninguna de las cepas tuvo una CIM por encima del punto de corte clínico (VOR), ni epidemiológico (ITC, ISA, AMB y CSF). POS fue la droga más potente frente a la colección de cepas evaluadas (media geométrica (GM) de CIM de 0,042 µg/ml). Conclusiones. Todos los aislamientos fueron tipificados como AFSS sensibles a los azoles según los puntos de corte clínico, posaconazol tuvo la mayor actividad antifúngica. Nuestros hallazgos aportan a incrementar la escasa información sobre la etiología y sensibilidad a los antifúngicos de uso clínico de las aspergilosis invasiva en nuestro país.

Introduction. Invasive Aspergillosis (IA) poses a significant threat to patients with chronic diseases and compromised immune systems, with Aspergillus fumigatus sensu stricto (AFSS) being the primary etiological agent. Accurate and timely diagnosis is crucial, particularly given the rising incidence of IA strains resistant to antifungals, necessitating molecular methods for typing. Methods. Twenty strains from Instituto de Medicina Tropical - Universidad Nacional Mayor de San Marcos, mycological collection, previously identified as Aspergillus fumigatus sensu lato through macroscopic and microscopic analysis, were studied. These strains were forwarded to the Universidad Nacional del Litoral for AFSS typing using a PCR screening based on CYP51A gene sequences. Antifungal susceptibility testing was performed for Voriconazole (VOR), Itraconazole (ITC), Posaconazole (POS), Isavuconazole (ISA), Anidulafungin (ANF), Caspofungin (CSF), and Amphotericin B (AMB), obtaining Minimum Inhibitory Concentrations (MICs) according to CLSI M38M51S-Ed3. Results. All 20 strains were identified as AFSS. None of the strains exhibited MICs above the clinical breakpoint (VOR) or the epidemiological cutoffs (ITC, ISA, AMB, and CSF). POS demonstrated the highest potency against the strain collection, with a geometric mean MIC of 0,042 µg/ml. Conclusions. All isolates were classified as azole-sensitive Aspergillus fumigatus sensu stricto (AFSS) based on clinical cutoff points, particularly posaconazole, which exhibited superior antifungal activity. Our findings contribute to augmenting the limited information on the etiology and clinical antifungal sensitivity of IA in our country.

Residencia de Medicina Física y Rehabilitación en el Perú: número de vacantes y análisis de los planes de estudios

Introducción. En el Perú existe un déficit de médicos fisiatras y los estándares para la formación de especialistas en Medicina Física y Rehabilitación (MFyR) no han sido actualizados desde el 2002. No existen estudios que aborden esta problemática. Objetivos. Describir el número de vacantes y analizar los planes de estudios de los programas de residencia de MFyR. Métodos. Estudio observacional descriptivo. Revisamos el número de vacantes para MFyR ofertadas en el período 2017-2022. Asimismo, recolectamos las variables de interés de los planes de estudios de los programas de residencia, incluyendo el abordaje de 30 competencias básicas recomendadas por la Sociedad Internacional de MFyR (ISPRM). Resultados. Durante el periodo 2017-2022, 11 universidades ofertaron 283 vacantes para MFyR, de las cuales 89,4% correspondieron a la ciudad de Lima. El número de vacantes mostró una tendencia a la baja desde el 2018 hasta el 2021. 7 de 11 planes de estudios abordaron por lo menos el 75% de las competencias básicas recomendadas por la ISPRM, y ninguno abordó el 100% de estas competencias. Además, encontramos heterogeneidad respecto a los cursos teóricos, el número de créditos académicos y las rotaciones externas permitidas. Conclusiones. En el Perú, el número de vacantes para MFyR disminuyó durante la pandemia por COVID-19, a pesar de su rol fundamental en la atención de la población afectada por la enfermedad y del déficit de médicos fisiatras. Ningún plan de estudios incluye todas las competencias básicas recomendadas por la ISPRM, lo cual alerta sobre la necesidad de actualizarlos y reestructurarlos.

Introduction. In Peru there is a shortage of physiatrists, and the standards for the training of specialists in Physical Medicine and Rehabilitation (PM&R) have not been updated since 2002. There are no studies that have focused on this problem. Objectives. To describe the number of PM&R positions and analyze the PM&R residency programs' curriculums. Methods. Descriptive observational study. We reviewed the number of PM&R positions offered in the 2017-2022 period. Likewise, we collected the variables of interest from the curriculums that offer this residency program, including the approach of 30 basic competencies recommended by the International Society of PM&R (ISPRM). Results. During the 2017-2022 period, 11 universities offered 283 PM&R positions, of which 89.4% corresponded to the city of Lima. The number of positions showed a downward trend from 2018 to 2021. 7/11 curriculums addressed at least 75% of the basic competencies recommended by the ISPRM, and none of them addressed 100% of these competencies. In addition, we found heterogeneity between universities respect to the theoretical courses taught, the number of academic credits and the external rotations allowed. Conclusions. In Peru, the number of PM&R positions decreased during the COVID-19 pandemic, despite its crucial role in caring for the affected population and the shortage of physiatrists. No curriculum includes all the basic competencies recommended by ISPRM, highlighting the need to update and restructure them.

Aceptación y reticencia a las vacunas contra COVID-19 en ingresantes a una universidad pública peruana durante la tercera ola pandémica

Introducción. Los estudiantes universitarios influyen en las decisiones de su familia y comunidad a favor de la vacunación. Objetivo. Identificar las principales razones para la aceptación o reticencia vacunal contra COVID-19 en ingresantes a una universidad pública. Métodos. Estudio transversal en una muestra de 408 estudiantes. Se preguntó si había completado las tres dosis de vacuna contra COVID-19 y la principal razón para la aceptación o reticencia vacunal. Se realizó un análisis descriptivo, se aplicó la prueba chi cuadrado y exacta de Fisher. Resultados. El 85,5% aceptó la vacuna principalmente por no querer contagiar a familiares (38,1%) y no querer enfermarse (27,8%). El 14,5% fue reticente, especialmente por prolongados tiempos de espera en vacunatorios (37,3%) y lejanía de los centros de vacunación (13,6%). Conclusiones. En los universitarios estudiados, el temor a la enfermedad impulsó la aceptación de la vacuna contra COVID-19 y la inaccesibilidad a los servicios de salud generó la reticencia.

Introduction. University students influence their family and community decisions in favor of vaccination. Objective. To identify the main reasons for COVID-19 vaccine acceptance or hesitancy among university entrants. Methods. A cross-sectional study in a sample of 408 students. We asked whether the student had completed the three doses the COVID-19 vaccine and the main reason for vaccine acceptance or hesitancy. A descriptive analysis was performed, the chi-square test and Fisher's exact were applied. Results. 85.5% accepted vaccination mainly because they did not want to infect family members (38.1%) and did not want to get sick (27.8%). 14.5% were hesitancy especially due to long waiting times in vaccination centers (37.3%) and distance from vaccination centers (13.6%). Conclusions. In the university students studied, the fear of disease drove COVID-19 vaccine acceptance and inaccessibility to health services generated vaccine hesitancy among university entrants.

The objective of this report was to describe the first 10 suspected cases of Guillain Barre Syndrome in Piura. It was possible to identify the presence of Campylobacter jejuni in the stool samples of 80% of the reported patients. It is very important to quickly and opportunely recognize the patient with a suspected diagnosis of Guillain Barré, and to carry out the necessary studies in an outbreak to identify the triggering agents of the condition.

Características clínicas en pacientes atendidos en una unidad de psiquiatría de emergencia en un hospital general de Perú

Introducción. En los últimos 10 a 20 años, la psiquiatría de emergencia ha experimentado un progreso constante en cuanto a la prestación de servicios altamente especializados y enfocados en el paciente. Este aumento global refleja desafíos en accesibilidad y calidad de atención. En el contexto peruano, la legislación de salud mental y múltiples directrices clínicas orientan la prestación de servicios, no obstante, la insuficiencia de datos representa una barrera significativa para la toma de decisiones informadas. Objetivo. Examinar y reportar las características sociodemográficas y clínicas de los pacientes evaluados en la Unidad de Psiquiatría de Emergencia del Hospital Nacional Guillermo Almenara Irigoyen (HNGAI), de Lima, Perú, y analizar la naturaleza de los cuadros sintomatológicos y sindrómicos. Métodos. Estudio descriptivo, transversal. Se estudiaron las interconsultas recibidas por la Unidad de Psiquiatría de Emergencia del HNGAI, entre julio y diciembre del 2022. Se aplicó un análisis factorial de los síntomas. Resultados. En 1037 pacientes vistos en interconsulta, la edad promedio fue 41,15 ± 23,52 años. El 65,2 % fueron mujeres. La tasa de derivación fue de 1,18 %. Los trastornos más frecuentes fueron los del humor (27,8 %); los síntomas más frecuentes fueron el afecto ansioso (47,3 %), insomnio (38,8 %) y ánimo depresivo (32,6 %).

Introduction. In the last 10 to 20 years, emergency psychiatry has undergone consistent progress in providing highly specialized and patient-focused services. This global advancement reflects challenges in accessibility and quality of care. In the Peruvian context, mental health legislation and various clinical guidelines guide service provision; however, the lack of data constitutes a significant barrier to informed decision-making. Objective. The objective of this study was to examine and report the sociodemographic and clinical characteristics of patients evaluated at the Emergency Psychiatry Unit of the National Guillermo Almenara Irigoyen Hospital (HNGAI) in Lima, Peru, and analyze the nature of the symptomatic and syndromic profiles present. Methods. This was a descriptive, cross-sectional study. Interconsultations received by the Emergency Psychiatry Unit of HNGAI between July and December 2022 were analyzed. A factorial analysis of symptoms was conducted. Results. Out of a total of 1037 patients seen in interconsultation, the mean age was 41.15 ± 23.52 years. 65.2% of the patients were female. The referral rate was 1.18%. Mood disorders (27.8%) were the most frequent diagnoses, with anxious affect (47.3%), insomnia (38.8%), and depressive mood (32.6%) being the most common symptoms. Antipsychotics (50.4%) were the most used treatment modality. Exploratory factor analysis of symptoms revealed the presence of seven important syndromic factors: psychotic, delirium, depressive-suicidal, obsessive-compulsive, negative, apathetic, and anxious. Conclusion. The typical patient in this sample was a female in the early forties. Mood disorders and anxious symptoms were the most prevalent. Exploratory factor analysis identified the presence of seven syndromes. There is a need to increase systematic data collection and investment in emergency psychiatry research to enhance the care provided to these patients.

Hospitalization and mortality during the pandemic in chronic hemodialysis patients and the general population in Peru / Hospitalização e mortalidade durante a pandemia em pacientes em hemodiálise crônica e na população em geral no Peru

ABSTRACT Background: Patients with chronic kidney disease have a higher risk of severe disease and mortality from COVID-19 than the general population. Objective: To compare hospitalization and mortality rates during the pandemic among chronic hemodialysis (HD) patients and the general population in Lima (Peru). Methods: This retrospective cohort included an assessment of the database of chronic HD patients of the health service providers of the social health insurance benefit networks of Lima and Callao between 2019 and 2021. Hospitalization and mortality rates were obtained for every 1,000 individuals, and variations in the percentages of COVID-19 cases and deaths were calculated. These rates were compared with those of the general population data and standardized by age and sex. Results: An average of 3,937 chronic HD patients were evaluated each month. Of these, 4.8% had COVID-19 and 64.97% were mild cases. The hospitalization rates per 1,000 patients were 19.5, 29.28, and 36.7 in 2019, 2020, and 2021, respectively. The mortality rates per 1,000 patients were 5.9, 9.74, and 11.49 in 2019, 2020, and 2021, respectively. When compared to the standardized general population, the peaks of both rates coincided with the plateaus of the waves during the pandemic. The hospitalization rate for COVID-19 was 12 times higher in HD patients than in the general population, and the mortality rate for COVID-19 was twice as high. Conclusion: HD patients had higher hospitalization and standardized mortality rates than the general population. Peaks in hospitalizations and mortality coincided with the plateaus of the first and second waves of the pandemic.

Resumo Histórico: Pacientes com DRC apresentam maior risco de doença grave e mortalidade por COVID-19 do que a população geral. Objetivo: Comparar taxas de hospitalização e mortalidade durante a pandemia entre pacientes em hemodiálise crônica (HD) e a população geral em Lima (Peru). Métodos: Esta coorte retrospectiva incluiu avaliação do banco de dados de pacientes em HD crônica dos prestadores de serviços de saúde das redes de benefícios do seguro social de saúde de Lima e Callao, entre 2019-2021. Obteve-se taxas de hospitalização e mortalidade para cada 1.000 indivíduos, e foram calculadas variações nas porcentagens de casos de COVID-19 e óbitos. Estas taxas foram comparadas com os dados da população geral e padronizadas por idade e sexo. Resultados: Uma média de 3.937 pacientes em HD crônica foram avaliados mensalmente. Destes, 4,8% tinham COVID-19, 64,97% eram casos leves. As taxas de hospitalização por 1.000 pacientes foram 19,5; 29,28; e 36,7 em 2019, 2020, e 2021, respectivamente. As taxas de mortalidade por 1.000 pacientes foram 5,9; 9,74 e 11,49 em 2019, 2020, e 2021, respectivamente. Quando comparados à população geral padronizada, os picos das taxas coincidiram com os platôs das ondas da pandemia. A taxa de hospitalização para COVID-19 foi 12 vezes maior em pacientes em HD do que na população geral e a taxa de mortalidade por COVID-19 foi duas vezes maior. Conclusão: Pacientes em HD apresentaram taxas de hospitalização e mortalidade padronizada mais elevadas do que a população geral. Os picos das hospitalizações e mortalidade coincidiram com os platôs da primeira e segunda ondas da pandemia.

Multiantigen print immunoassay (MAPIA) for the diagnosis of neurocysticercosis: a single-center diagnostic optimization and accuracy study in Lima, Peru.

Neurocysticercosis (NCC) is the most common helminthic infection of the human central nervous system. The antibody detection assay of choice is the enzyme-linked immunoelectrotransfer blot assay using lentil-lectin purified parasite antigens (LLGP-EITB, Western blot), an immunoassay with exceptional performance in clinical samples. However, its use is mainly restricted to a few research laboratories because the assay is labor-intensive and requires sophisticated equipment, expertise, and large amounts of parasite material for preparation of reagents. We report a new immunoprint assay (MAPIA) that overcomes most of these barriers. We initially compared the performance of five different antigen combinations in a subset of defined samples in the MAPIA format. After selecting the best-performing assay format (a combination of rGP50 + rT24H + sTs14 antigens), 148 archived serum samples were tested, including 40 from individuals with parenchymal NCC, 40 with subarachnoid NCC, and 68 healthy controls with no evidence of neurologic disease. MAPIA using three antigens (rGP50 + rT24H + sTs14) was highly sensitive and specific for detecting antibodies in NCC. It detected 39 out of 40 (97.5%) parenchymal NCC cases and 40/40 (100%) subarachnoid cases and was negative in 67 out of 68 (98.53%) negative samples. MAPIA using three recombinant and synthetic antigens is a simple and economical tool with a performance equivalent to the LLGP-EITB assay for the detection of specific antibodies to NCC. The MAPIA overcomes existing barriers to adoption of the EITG LLGP and is a candidate for worldwide use.

Trends in gastric cancer mortality 2005-2020 in Peru and its geographical areas: A joinpoint regression analysis.

BACKGROUND: Gastric cancer (GC) is the leading cause of cancer death in Peru. However, information regarding trends in mortality rates in Peru and its geographical areas in the last few decades is lacking. Our objective was to describe GC mortality rates in Peru between 2005 and 2020. METHODS: Age standardized mortality rates (ASMR) were calculated per 100,000 person-years using the world SEGI standard population. Joinpoint regression analysis was performed to examine mortality trends. The analysis of the last 5 years was performed for Peru and its geographical areas. RESULTS: GC mortality rates in 2005 and in 2020 were 13.81 and 10.52, respectively, for men and 11.81 and 8.06, respectively, for women. Between 2016 and 2020, Huanuco and Huancavelica reported the highest mortality rates (≥20 deaths per 100,000). In men, Peru and the highlands region reported significant decreases in GC mortality rates in both sexes for some periods. Coastal region significant decreased by 2.6 % in all periods for women. In both sexes, six provinces reported significant decreases in GC mortality rates. CONCLUSION: Although GC mortality rates in Peru have declined over the past 16 years. They are still one of the highest in the Latin American and Caribbean region. It is important that the Peruvian State seek to reduce the mortality of this disease through prevention efforts, timely detection and treatment in all patients.

Postinfectious bronchiolitis obliterans in children: case series at a pediatric hospital in Peru.

BACKGROUND: Postinfectious bronchiolitis obliterans is a rare lung disease; there are limited reports in South America. CASE REPORT: We report 10 patients with this disease diagnosed at the Instituto Nacional de Salud del Niño-Breña (Lima-Peru). The median age at diagnosis was 19 months and all patients had a history of severe acute respiratory infection. The most frequent symptoms were cough, respiratory distress, wheezing, and hypoxemia. The mosaic attenuation pattern was the most frequent on the tomography. All the patients had positive serology for adenovirus. The treatment received was methylprednisolone pulses, azithromycin, hydroxychloroquine, and inhaled corticosteroids. No patient died during the follow-up. CONCLUSIONS: In previously healthy children with a history of severe acute respiratory infection and persistent bronchial obstructive symptoms, the diagnosis of postinfectious bronchiolitis obliterans should be considered. This is the first report in Peru with a therapeutic regimen adapted to our institution.

INTRODUCCIÓN: La bronquiolitis obliterante postinfecciosa es una enfermedad pulmonar poco frecuente; existen limitados reportes en Sudamérica. CASO CLÍNICO: En esta serie se reportan 10 pacientes con esta enfermedad diagnosticados en el Instituto Nacional de Salud del Niño-Breña (Lima-Perú). La mediana de edad al diagnóstico fue de 19 meses. Todos los pacientes presentaron el antecedente de infección respiratoria aguda grave. Los síntomas más frecuentes fueron tos, dificultad respiratoria, sibilancias e hipoxemia; el patrón de atenuación en mosaico fue la característica más frecuente en la tomografía. Todos tenían serología positiva para adenovirus. Se administró tratamiento con pulsos de metilprednisolona, azitromicina, hidroxicloroquina y corticoides inhalados. Ningún paciente falleció durante el seguimiento. CONCLUSIONES: En los niños previamente sanos con antecedente de infección respiratoria aguda grave y sintomatología obstructivo bronquial persistente se debe considerar el diagnóstico de bronquiolitis obliterante postinfecciosa. Este es el primer reporte en Perú con un régimen terapéutico adaptado a nuestra institución.
