      Tenorio-Mucha, Janeth; Romero-Albino, Zoila; Roncal-Vidal, Vasti; Cuba-Fuentes, María Sofía (Medical Body of the Almanzor Aguinaga Asenjo National Hospital, 2021-10-21)
      Objetive: To evaluate the quality of life of older adults who belong to the Seniors Centers (CAM) of the Social Security during the COVID-19 pandemic. Material and methods: Data were collected through telephone calls to older adults aged 60 years and over in the CAM. Quality of life was assessed with the EQ-5D-3L questionnaire, which considers the dimensions of mobility, self-care, activities of daily living, pain/discomfort and anxiety/depression and an analog scale from 0 to 100. The presence of depression, anxiety, comorbidities and functional status were also measured. A bivariate analysis with nonparametric tests was performed to assess the association between covariates and the quality of life analog scale. In addition, a simple regression analysis was performed using generalized linear models of the Poisson family to evaluate variables associated with the presence of problems in the quality of life dimensions. Results: A total of 99 older adults participated, mostly women (84.9%) and with an average age of 73.1 years, 83.3% had a higher education level and 86.7% lived with their spouse. Older adults with obesity, lung disease, inability to manage their own money, feeling fatigued, and hearing problems reported a lower than average score (<78.9) on the analogous quality of life scale. Osteoarticular diseases and feeling fatigued increase the likelihood of having problems with mobility, performing daily activities, and pain/discomfort. Conclusions: Older adults quality of life is influenced by multiple factors that must be addressed to improve their physical and mental well-being.

    • Quantitative real-time polymerase chain reaction for enteropathogenic Escherichia coli: a tool for investigation of asymptomatic versus symptomatic infections

      Barletta, Francesca; Ochoa, Theresa J.; Mercado, Erik H.; Ruiz, Joaquim; Ecker, Lucie; Lopez, Giovanni; Mispireta, Monica; Gil, Ana I.; Lanata, Claudio F.; Cleary, Thomas G. (Oxford University Press, 2015-05-30)
      BACKGROUND: Enteropathogenic Escherichia coli (EPEC) strains are pediatric pathogens commonly isolated from both healthy and sick children with diarrhea in areas of endemicity. The aim of this study was to compare the bacterial load of EPEC isolated from stool samples from children with and without diarrhea to determine whether bacterial load might be a useful tool for further study of this phenomenon. METHODS: EPEC was detected by polymerase chain reaction (PCR) of colonies isolated on MacConkey plates from 53 diarrheal and 90 healthy children aged <2 years. DNA was isolated from stool samples by cetyltrimethylammonium bromide extraction. To standardize quantification by quantitative real-time PCR (qRT-PCR), the correlation between fluorescence threshold cycle and copy number of the intimin gene of EPEC E2348/69 was determined. RESULTS: The detection limit of qRT-PCR was 5 bacteria/mg stool. The geometric mean load in diarrhea was 299 bacteria/mg (95% confidence interval [CI], 77-1164 bacteria/mg), compared with 29 bacteria/mg (95% CI, 10-87 bacteria/mg) in control subjects (P = .016). Bacterial load was significantly higher in children with diarrhea than in control subjects among children <12 months of age (178 vs 5 bacteria/mg; P = .006) and among children with EPEC as the sole pathogen (463 vs 24 bacteria/mg; P = .006). CONCLUSIONS: EPEC load measured by qRT-PCR is higher in diarrheal than in healthy children. qRT-PCR may be useful to study the relationship between disease and colonization in settings of endemicity.

    • Quiste de colédoco en una lactante de tres meses de edad: diagnóstico prenatal y manejo quirúrgico

      Corrochano Fatule, Mariana; Llanos Rodriguez, Rodolfo; Garcia, Alcides; [email protected] (Asociación Interciencia, 2014-11-03)
      El quiste de colédoco es una patología poco común, diagnosticada generalmente después del nacimiento; pero en los últimos tiempos el diagnóstico prenatal ha tomado mayor importancia, pues permite una intervención precoz y brinda un mejor pronóstico a los pacientes. Se presenta el caso de una lactante que fue diagnosticada mediante ecografía obstétrica, a las 21 semanas de vida intrauterina; confirmándose luego el diagnóstico por medio de resonancia magnética. La paciente fue operada a los tres meses de vida, realizándosele una quistectomía, colecistectomía y derivación biliodigestiva en Y de Roux, con evolución posoperatoria favorable.

    • Radiographic and Clinical Brain Infarcts in Cardiac and Diagnostic Procedures: A Systematic Review and Meta-Analysis.

      Cho, Sung-Min; Deshpande, Abhishek; Pasupuleti, Vinay; Hernandez, Adrian V.; Uchino, Ken (American Heart Association, 2017-10)
      BACKGROUND AND PURPOSE: The incidence of periprocedural brain infarcts varies among cardiovascular procedures. In a systematic review, we compared the ratio of radiographic brain infarcts (RBI) to strokes and transient ischemic attacks across cardiac and vascular procedures. METHODS: We searched MEDLINE and 5 other databases for brain infarcts in aortic valve replacement, coronary artery bypass grafting, cardiac catheterization, and cerebral angiogram through September 2015. We followed the PRISMA (preferred reporting items for systematic reviews and meta-analyses) recommendations. We defined symptomatic rate ratio (RR) as ratio of stroke plus transient ischemic attack rate to RBI rate. RESULTS: Twenty-nine studies involving 2124 subjects met the inclusion criteria. In meta-analysis of aortic valve replacements with 494 people, 69.4% (95% confidence interval (CI), 57.6%-81.4%) had RBIs, whereas 3.6% (95% CI, 2.0%-5.2%) had clinical events (RR, 0.08; 95% CI, 0.05-0.12). Coronary artery bypass grafting among 204 patients had 27.4% (95% CI, 6.0%-48.8%) RBIs and 2.4% (95% CI, 0.3%-4.5%) clinical events (RR, 0.11; 95% CI, 0.05-0.26). Cardiac catheterization among 833 people had 8.0% (95% CI, 4.1%-12.0%) RBIs, and 0.6% (95% CI, 0.1%-1.1%) had clinical events (RR, 0.16; 95% CI, 0.08-0.31). Cerebral angiogram among 593 people had 12.8% (95% CI, 6.6-19.0) RBIs and 0.6% (95% CI, 0%-13%) clinical events (RR, 0.10; 95% CI, 0.04-0.27). The RR of all procedures was 0.10 (95% CI, 0.07-0.13) without differences in the RRs across procedures (P=0.29). CONCLUSIONS: One of 10 people with periprocedural RBIs during cardiac surgeries and invasive vascular diagnostic procedures resulted in strokes or transient ischemic attacks, which may serve as a potential surrogate marker of procedural proficiency and perhaps as a predictor of risk for periprocedural strokes.
    • Radiographic and symptomatic brain ischemia in CEA and CAS: A systematic review and meta-analysis

      Cho, Sung-Min; Deshpande, Abhishek; Pasupuleti, Vinay; Hernandez, Adrian V.; Uchino, Ken (American Academic of Neurology, 2017-10-11)
      OBJECTIVE: In a systematic review, we compared ratio of new periprocedural radiographic brain ischemia (RBI) to the number of strokes and TIAs among patients undergoing carotid endarterectomy (CEA) and carotid artery stenting (CAS). METHODS: We searched 5 databases for entries related to brain ischemia in CEA or CAS from inception through September 2015. We included articles with CEA or CAS and systematic performance of preprocedural and postprocedural brain MRI and reporting of RBI and stroke incidence. We calculated a symptomatic risk ratio of number of strokes and TIAs to RBI. Random effects models were used. RESULTS: Fifty-nine studies (5,431 participants) met the inclusion criteria. There were 22 cohorts in CEA, 34 in CAS with distal protection, 8 in CAS with proximal protection, 9 in CAS without protection, and 9 in CAS with unspecified devices. Overall, 30.7% (95% confidence interval [CI] 26.6%-34.7%) had RBI, while 3.2% (95% CI 2.6%-3.8%) had clinical strokes or TIAs, with a stroke and TIA to RBI weighted ratio of 0.18 (95% CI 0.15-0.22). CEA had lower incidence of RBI compared to CAS (13.0% vs 37.4%) and also lower number of strokes and TIAs (1.8% vs 4.1%). The stroke and TIA to RBI ratio did not differ across 5 different types of carotid interventions (p = 0.58). CONCLUSIONS: One in 5 persons with periprocedural radiographic brain ischemia during CEA and CAS had strokes and TIAs. The stable ratio of stroke and TIA to radiographic ischemia suggests that MRI ischemia could serve as a surrogate measure of periprocedural risk.

    • Recurrence of urinary tract infections due to escherichia coli and its association with antimicrobial resistance

      Ormeño, Maria Angeles; Ormeño, Maria José; Quispe, Antonio M.; Arias-Linares, Miguel Angel; Linares, Elba; Loza, Felix; Ruiz, Joaquim; Pons, Maria J. (Mary Ann Liebert Inc., 2022-02-01)
      We analyzed the association between antibiotic resistance and recurrent urinary tract infection (rUTI) by Escherichia coli. Susceptibility levels to 14 antimicrobial agents and the presence of extended-spectrum β-lactamases (ESBL) were established using MicroScan. Incidences of multidrug resistant (MDR), extensively drug resistant (XDR), and ESBL-producer isolates as well as rUTIs were estimated. The time to recurrence was established adjusted for number of antibiotic-resistant families and MDR as predictors of interest, respectively. Overall, 8,553 urinary tract infection (UTI) cases related to E. coli, including 963 rITU, were analyzed with levels of resistance >30% in all cases, except for amikacin, nitrofurantoin, and carbapenems. The incidence of rUTI was of 11.3%, being 46.5%, 24.3%, and 42.5% for MDR, XDR, and ESBLs, respectively. Bivariate analysis showed that rUTI was associated with age, gender, resistance to specific antimicrobials, MDR, and XDR. The number of antibiotic families tested as resistant, MDR, XDR, gender, and age were associated with time to recurrence when adjusted for number of antibiotic families, and MDR, gender, and age were related when adjusted for MDR. High rates of antibiotic resistance to the usual antibiotics was observed in E. coli causing UTI, with female sex, age, and antibiotic resistance being risk factors for the development of rUTI.

    • Reducing salt in bread: a quasi-experimental feasibility study in a bakery in Lima, Peru

      Saavedra Garcia, Lorena; Sosa Zevallos, Vanessa; Diez Canseco, Francisco (The Nutrition Society, 2015-05-22)
      Objectives: To explore salt content in bread and to evaluate the feasibility of reducing salt contained in ‘pan francés’ bread. Design: The study had two phases. Phase 1, an exploratory phase, involved the estimation of salt contained in bread as well as a triangle taste test to establish the amount of salt to be reduced in ‘pan francés’ bread without detection by consumers. In Phase 2, a quasi-experimental, pre–post intervention study assessed the effects of the introduction of low-salt bread on bakery sales. Setting: A municipal bakery in Miraflores, Lima, Peru. Subjects: Sixty-five clients of the bakery in Phase 1 of the study; sales to usual costumers in Phase 2. Results: On average, there was 1·25 g of salt per 100 g of bread. Sixty-five consumers were enrolled in the triangle taste test: fifty-four (83·1 %) females, mean age 58·9 (SD 13·7) years. Based on taste, bread samples prepared with salt reductions of 10 % (P = 0·82) and 20 % (P =0·37) were not discernible from regular bread. The introduction of bread with 20 % of salt reduction, which contained 1 g of salt per 100 g of bread, did not change sales of ‘pan francés’ (P=0·70) or other types of bread (P =0·36). Results were consistent when using different statistical techniques. Conclusions: The introduction of bread with a 20 % reduction in salt is feasible without affecting taste or bakery sales. Results suggest that these interventions are easily implementable, with the potential to contribute to larger sodium reduction strategies impacting the population’s cardiovascular health.

    • Reforma del sector salud en el Perú: Derecho, gobernanza, cobertura universal y respuesta contra riesgos sanitarios

      Velásquez, Aníbal; Suarez, Dalia; Nepo-Linares, Edgardo; [email protected] (Instituto Nacional de Salud (INS), 2016-09)
      In 2013, Peru initiated a reform process under the premise of recognizing the nature of health as a right that must be protected by the state. This reform aimed to improve health conditions through the elimination or reduction of restrictions preventing the full exercise of this right, and the consequent approach aimed to protect both individual and public health and rights within a framework characterized by strengthened stewardship and governance, which would allow system conduction and effective responses to risks and emergencies. The reform led to an increase in population health insurance coverage from 64% to 73%, with universalization occurring through the SIS affiliation of every newborn with no other protection mechanism. Health financing increased by 75% from 2011, and the SIS budget tripled from 570 to 1,700 million soles. From 2012 to May 2016, 168 health facilities have become operational, 51 establishments are nearing completion, and 265 new projects are currently under technical file and work continuity with an implemented investment of more than 7 billion soles. Additionally, this reform led to the approval of the Ministry of Health intervention for health emergencies and strengthened the health authority of the ministry to implement responses in case of risks or service discontinuity resulting from a lack of regional or local government compliance with public health functions.

    • Refractory Thrombocytopenia Responds to Octreotide Treatment in a Case of Evans Syndrome with Gastric Neuroendocrine Tumor

      Chung Delgado, Kocfa; Revilla Montag, Alejandro; Guillén Bravo, Sonia; Ríos Díaz, Hugo; Alva Muñoz, José C. (Hindawi Publishing Corporation, 2014-03-12)
      A 37-year-old woman with history of Evans Syndrome with poor response to high-dose corticoid treatment presented to the emergency department with gastrointestinal and vaginal bleeding. The patient was later diagnosed with severe thrombocytopenia and a stage G1, well-differentiated gastric neuroendocrine tumor, confirmed by a biopsy. A total gastrectomy was performed to eradicate the tumor. After being treated with a total splenectomy for her Evans Syndrome with no clinical or laboratory improvement, she began regular treatment with octreotide on the basis of a possible hepatic metastasis. Days after the initiation of the octreotide, an increase in the platelet count was evidenced by laboratory findings, from 2,000 platelets/mm3 to 109,000 platelets/mm3 . Weeks later, the hepatic metastasis is discarded by a negative octreotide-body scan, and the octreotide treatment was interrupted. Immediately after the drug interruption, a progressive and evident descent in the platelet count was evidenced (4000 platelets/mm3 ). The present case report highlights the possible association between octreotide treatment and a severe thrombocytopenia resistant to conventional treatment.

    • Relationship between stunting in children 6 to 36 months of age and maternal employment status in Peru: A sub-analysis of the Peruvian Demographic and Health Survey

      Chávez-Zárate, Airin; Maguiña, Jorge L.; Quichiz-Lara, Antoinette Danciana; Zapata-Fajardo, Patricia Edith; Mayta-Tristán, Percy (Public Library of Science, 2019-04-01)
      Objectives This study aimed to determine the relationship between stunting in children 6 to 36 months old and maternal employment status in Peru. Methods A secondary data analysis was conducted using information from the Demographic and Health Survey (DHS) in Peru. We used a representative sample of 4637 mother-child binomials to determine the association between stunting in children 6 to 36 months of age and the employment status of their mothers. Results The prevalence of stunting among children was 15.9% (95% CI: 13.9–16.7). The prevalence of working mothers was 63.7%. No association was found between maternal employment status and the presence of stunting in children [prevalence ratio (PR) = 1.04; 95% confidence interval (95% CI): 0.9 to 1.2; p = 0.627). However, on multivariate analysis we found that the prevalence of stunting was significantly higher among children of mothers performing unpaid work (12.4%) (PR = 1.38; 95% CI: 1.2–1.6; p < 0.001) compared with those of paid working mothers. Conclusion No significant association was found between maternal employment status and the presence of stunting in children 6 to 36 months of age. However, children of mothers doing unpaid work are at higher risk of stunting. These findings support the implementation of educational programs and labour policies to reduce the prevalence of stunting among children.

    • Religious affiliation and the intention to choose psychiatry as a specialty among physicians in training from 11 Latin American countries

      Calizaya-Gallegos, Carlo; Mayta-Tristan, Percy; Pereyra-Elías, Reneé; José Montenegro-Idrogo, Juan; Avila-Figueroa, Johana; Benítez-Ortega, Ingrid; Cabrera-Enriquez, John; Calixto, Omar-Javier; Pablo Cardozo-López, Juan; Grandez-Urbina, José Antonio; Moreno-Loaiza, Oscar; Rodriguez, Manuel A.; Sepúlveda-Morales, Roxana; Sierra-Avendaño, Jairo A.; Carreño, Fabian; Vásquez-García, Gelsing Richard; Vasquez-Sullca, Roy R.; Yescas, Gilberto; [email protected] (SAGE Publications Ltd, 2018)
      The worldwide scarcity of psychiatrists makes the identification of the factors associated with the intention to choose this specialty an important issue. This study aims to evaluate the association between religious affiliation and the intention to choose psychiatry as a specialty among medical students from 11 Latin American countries. We conducted a cross-sectional, multi-country study that included first- and fifth-year students of 63 medical schools in 11 Latin-American countries between 2011 and 2012. The main outcome and measures were the intention to pursue psychiatry as a specialty over other specialties (yes/no) and religious affiliation (without: atheist/agnostic; with: any religion). A total of 8308 participants were included; 53.6% were women, and the average age was 20.4 (SD = 2.9) years. About 36% were fifth-year students, and 11.8% were not affiliated with any religion. Only 2.6% had the intention to choose psychiatry; the highest proportion of students with the intention to choose psychiatry was among students in Chile (8.1%) and the lowest among students in Mexico (1.1%). After adjusting for demographic, family, academic as well as personal and professional projection variable, we found that those who had no religious affiliation were more likely to report the intention to become a psychiatrist [OR: 2.92 (95%CI: 2.14-4.00)]. There is a strong positive association between not having a religious affiliation and the intention to become a psychiatrist. The possible factors that influence this phenomenon must be evaluated in greater depth, ideally through longitudinal research.
