Glaucoma medical treatment as a predictor of XEN45 subconjunctival gel implant hypotensive efficacy.

PURPOSE: The aim of this study was to determine the preoperative characteristics influencing hypotensive efficacy of the XEN45 gel stent in patients with open-angle glaucoma at one-year follow-up. MATERIALS AND METHODS: This was a retrospective multicentre study. All patients who underwent XEN45 gel stent implantation between January 2017 and January 2021 were included. The main study outcome was the assessment of one-year postoperative intraocular pressure (IOP) and glaucoma medication differences according to the number and type of preoperative topical treatments or glaucoma surgery, glaucoma stage and time since diagnosis. Follow-up period was 1-year post-surgery in all cases. IOP reduction and surgery success (not requiring reoperation or pressure failures [IOP > 18 mmHg and < 20% reduction in IOP]), safety and cost savings in topical glaucoma therapy after surgery were secondarily assessed. Linear regression analysis to determine the preoperative parameters influence on 1-year postoperative results was performed. RESULTS: XEN45 gel stent was implanted in 85 patients. One-year postoperative mean IOP dropped from 20.6 ± 4.1 to 13.7 ± 2.8 mmHg (p < 0.0001). Likewise, mean number of topical treatments decreased from 2.05 ± 0.9 to 0.36 ± 0.65 (p < 0.001). Both were mainly influenced by the number of preoperative glaucoma treatments, such that for each one-glaucoma medication increase, postoperative intraocular pressure increased by 1.18 mmHg (95% CI 0.56-1.79, p < 0.0001) and number of glaucoma medications increased by 0.3 (95% CI 0.16-0.43, p < 0.001). Overall success rates (with and without supplemental glaucoma medication use) were 97.6% (95% CI 94.5-100%), 87.1% (95% CI 80.2-87.1%) and 61.2% (95% CI 51.6-72.5%) at 3, 6 months and 1 year after surgery. No sight-threatening adverse events were reported. Mean annual cost savings on medical treatment since surgery reached EUR 251.19 ± 169. 93 euros. CONCLUSIONS: One year after surgery, XEN45 gel implant significantly reduced IOP and number of topical medications with an adequate safety profile being both mainly influenced by the number of preoperative glaucoma treatments.

Peritoneal Dialysis during the COVID-19 Pandemic Is an Effective Treatment in Developing Countries: A Report from Mexico.

INTRODUCTION: During the height of the coronavirus disease-19 (COVID-19) pandemic, some renal replacement therapy (RRT) modalities were insufficient, forcing medical centers to diversify the RRT modalities offered. In this study, we reported the outcomes of chronic peritoneal dialysis (PD) patients and acute PD in critically ill patients during COVID-19 pandemic in a tertiary care medical center in Mexico. METHODS: This descriptive, longitudinal, observational, retrospective study included 47 adult patients with atypical pneumonia in a tertiary care medical center in Mexico during the first and second waves of the COVID-19 pandemic. Chronic PD patients and PD incident patients due to acute kidney injury (AKI) were included. RESULTS: Forty-seven patients were studied (29 chronic PD patients and 18 incident PD patients due to AKI); median age was 59 (48-68) years; 63.8% were men. The ultrafiltrate volume per day was 815 (596.1-1,193.2) mL. Overall mortality was 61.7%, 55.2% in chronic PD patients, and 72.2% in PD incident patients due to AKI. A higher Sequential Organ Failure Assessment (SOFA) score, the need for mechanical ventilation at admission, and the requirement for vasopressors were predictors for mortality (p < 0.01). CONCLUSION: In low- and lower-middle-income countries, PD was a valid alternative for RRT during the COVID-19 pandemic. In AKI patients, PD can correct hyperkalemia, acidosis, uremia, and volume overload; however, there was higher mortality in PD incident patients due to AKI. The main risk factors for mortality were a high SOFA score at admission, the need for invasive mechanical ventilation, and the requirement for vasopressors.

Utility of the IMPACT score for predicting heart transplant mortality. Analysis on a contemporary cohort of the Spanish Heart Transplant Registry.

INTRODUCTION AND OBJECTIVES: The Index for Mortality Prediction After Cardiac Transplantation (IMPACT) score was derived and validated as a predictor of mortality after heart transplantation (HT). The primary objective of this work is to externally validate the IMPACT score in a contemporary Spanish cohort. METHODS: Spanish Heart Transplant Registry data were used to identify adult (>16 years) HT patients between January 2000 and December 2015. Retransplantation, multiorgan transplantation and patients in whom at least one of the variables required to calculate the IMPACT score was missing were excluded from the analysis (N = 2810). RESULTS: Median value of the IMPACT score was five points (IQR: 3, 8). Overall, 1-year survival rate was 79.1%. Kaplan-Meier 1-year survival rates by IMPACT score categories (0-2, 3-5, 6-9, 10-14, ≥15) were 84.4%, 81.5%, 79.3%, 77.3%, and 58.5%, respectively (Log-Rank test: p < .001). Performance analysis showed a good calibration (Hosmer-Lemeshow chi-square for 1 year was 7.56; p = .47) and poor discrimination ability (AUC-ROC .59) of the IMPACT score as a predictive model. CONCLUSIONS: In a contemporary Spanish cohort, the IMPACT score failed to accurately predict the risk of death after HT.

Depth of field and visual performance after implantation of a new hydrophobic trifocal intraocular lens.

PURPOSE: To assess the depth of field (DOF) by means of defocus curve analysis applying different visual acuity criteria in patients following cataract surgery and bilateral implantation of a new trifocal diffractive intraocular lens (IOL). METHODS: Fifty eyes of 25 consecutive patients who underwent implantation of the Asqelio™ trifocal IOL (AST Products Inc., USA) were enrolled in this observational prospective study. Monocular subjective DOF was obtained from defocus curves with absolute and relative criteria of tolerance for different visual acuities values. Patient's visual satisfaction, postoperative refraction and visual acuity at far, intermediate (67 cm) and near (40 cm) distances were also measured at 1 and 3-months post-surgery. Analysis of variance was used to assess differences in refractive error after the surgical procedure, and paired t-tests were used to assess differences in VA. Patient satisfaction results were reported as percentages. RESULTS: Spherical equivalent was 0.05 ± 0.23 D and residual cylinder 0.01 ± 0.23 D 3-months after the surgery. Absolute DOF obtained was 3.29 ± 0.91 D considering 0.1 LogMAR as cut-off value, and 4.82 ± 0.69 D when 0.3 logMAR as cutoff value. Relative DOF considering a drop of 0.1 logMAR from maximum visual acuity was 2.57 ± 0.82 D, and 1.27 ± 0.70 D when a drop of 0.04 logMAR was considered. Visual acuities obtained 3-months after the surgery were 0.03 ± 0.13, - 0.05 ± 0.06, 0.03 ± 0.08 and 0.04 ± 0.08 logMAR for uncorrected and best-corrected for distance, and best distance-corrected for intermediate and near distances, respectively. Average response to visual satisfaction queries was 8.24/10 at distance, 8.04/10 at intermediate, and 7.88/10 at near. CONCLUSIONS: Patients implanted with this trifocal IOL showed a significant improvement in visual acuity at different distances providing wide absolute and relative DOF values. The outcomes demonstrate that this lens is predictable yielding good patient satisfaction rates.

Coronavirus Disease 2019 in Solid Organ Transplant: A Multicenter Cohort Study.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has led to significant reductions in transplantation, motivated in part by concerns of disproportionately more severe disease among solid organ transplant (SOT) recipients. However, clinical features, outcomes, and predictors of mortality in SOT recipients are not well described. METHODS: We performed a multicenter cohort study of SOT recipients with laboratory-confirmed COVID-19. Data were collected using standardized intake and 28-day follow-up electronic case report forms. Multivariable logistic regression was used to identify risk factors for the primary endpoint, 28-day mortality, among hospitalized patients. RESULTS: Four hundred eighty-two SOT recipients from >50 transplant centers were included: 318 (66%) kidney or kidney/pancreas, 73 (15.1%) liver, 57 (11.8%) heart, and 30 (6.2%) lung. Median age was 58 (interquartile range [IQR] 46-57), median time post-transplant was 5 years (IQR 2-10), 61% were male, and 92% had ≥1 underlying comorbidity. Among those hospitalized (376 [78%]), 117 (31%) required mechanical ventilation, and 77 (20.5%) died by 28 days after diagnosis. Specific underlying comorbidities (age >65 [adjusted odds ratio [aOR] 3.0, 95% confidence interval [CI] 1.7-5.5, P < .001], congestive heart failure [aOR 3.2, 95% CI 1.4-7.0, P = .004], chronic lung disease [aOR 2.5, 95% CI 1.2-5.2, P = .018], obesity [aOR 1.9, 95% CI 1.0-3.4, P = .039]) and presenting findings (lymphopenia [aOR 1.9, 95% CI 1.1-3.5, P = .033], abnormal chest imaging [aOR 2.9, 95% CI 1.1-7.5, P = .027]) were independently associated with mortality. Multiple measures of immunosuppression intensity were not associated with mortality. CONCLUSIONS: Mortality among SOT recipients hospitalized for COVID-19 was 20.5%. Age and underlying comorbidities rather than immunosuppression intensity-related measures were major drivers of mortality.

Spatial ecology of conflicts: unravelling patterns of wildlife damage at multiple scales.

Human encroachment into natural habitats is typically followed by conflicts derived from wildlife damage to agriculture and livestock. Spatial risk modelling is a useful tool to gain the understanding of wildlife damage and mitigate conflicts. Although resource selection is a hierarchical process operating at multiple scales, risk models usually fail to address more than one scale, which can result in the misidentification of the underlying processes. Here, we addressed the multi-scale nature of wildlife damage occurrence by considering ecological and management correlates interacting from household to landscape scales. We studied brown bear (Ursus arctos) damage to apiaries in the North-eastern Carpathians as our model system. Using generalized additive models, we found that brown bear tendency to avoid humans and the habitat preferences of bears and beekeepers determine the risk of bear damage at multiple scales. Damage risk at fine scales increased when the broad landscape context also favoured damage. Furthermore, integrated-scale risk maps resulted in more accurate predictions than single-scale models. Our results suggest that principles of resource selection by animals can be used to understand the occurrence of damage and help mitigate conflicts in a proactive and preventive manner.

Subjective and objective depth of field measures in pseudophakic eyes: comparison between extended depth of focus, trifocal and bifocal intraocular lenses.

PURPOSE: To evaluate different intraocular lens (IOL) designs and to determine whether extended depth of focus (EDOF) lenses provide a higher depth of field (DOF) than the rest considering both subjective and objective measurements. METHODS: A total of 100 eyes undergoing cataract surgery were divided into six groups depending on the IOL implanted: bifocal designs were Tecnis ZMB and ZLB (Abbott Laboratories, Illinois, USA), trifocal designs were Finevision (PhysIOL, Liège, Belgium) and AT LISA Tri (Carl Zeiss Meditec., Jena, Germany) and EDOF designs were Symfony (Abbott Laboratories, Illinois, USA) and MiniWell (SIFI MedTech, Catania, Italy). Subjective DOF was obtained from defocus curves for the range of vergences which provide a VA over 0.1 LogMAR and 0.2 LogMAR. Aberrometry was measured and Visual Strehl Optical Transference Function (90%) was used to quantify objectively the DOF. RESULTS: Symfony IOL group showed better subjective and objective DOF compared to the rest of IOL groups, with statistically significant differences (p < 0.001). Comparison between subjective and objective DOF showed that subjective measures were higher for all IOLs, being these differences statistically significant for all groups when compared with objective measures (p < 0.001). CONCLUSION: Objective and subjective measures of DOF are not comparable due to differences in methodologies and criterions to define the level of degradation acceptance. Nevertheless, both objective and subjective measures demonstrate a greater DOF for EDOF designs compared to bifocal and trifocal IOLs, being the Symfony IOL the one providing higher levels of subjective and objective DOF.

In Vitro Grown Micro-Tissues for Cardiac Cell Replacement Therapy in Vivo.

BACKGROUND/AIMS: Different approaches have been considered to improve heart reconstructive medicine and direct delivery of pluripotent stem cell-derived cardiomyocytes (PSC-CMs) appears to be highly promising in this context. However, low cell persistence post-transplantation remains a bottleneck hindering the approach. Here, we present a novel strategy to overcome the low engraftment of PSC-CMs during the early post-transplantation phase into the myocardium of both healthy and cryoinjured syngeneic mice. METHODS: Adult murine bone marrow mesenchymal stem cells (MSCs) and PSC-CMs were co-cultured on thermo-responsive polymers and later detached through temperature reduction, resulting in the protease-free generation of cell clusters (micro-tissues) composed of both cells types. Micro-tissues were transplanted into healthy and cryo-injured murine hearts. Short term cell retention was quantified by real-time-PCR. Longitudinal cell tracking was performed by bioluminescence imaging for four weeks. Transplanted cells were further detected by immunofluorescence staining of tissue sections. RESULTS: We demonstrated that in vitro grown micro-tissues consisting of PSC-CMs and MSCs can increase cardiomyocyte retention by >10fold one day post-transplantation, but could not fully rescue a further cell loss between day 1 and day 2. Neutrophil infiltration into the transplanted area was detected in healthy hearts and could be attributed to the cellular implantation rather than tissue damage exerted by the transplantation cannula. Injected PSC-CMs were tracked and successfully detected for up to four weeks by bioluminescence imaging. CONCLUSION: This approach demonstrated that in vitro grown micro-tissues might contribute to the development of cardiac cell replacement therapies.

Testing the stability of internal quality controls stored in the automated Atellica Solution refrigerated storage module.

Objectives: Atellica Solution (AS) is a platform that incorporates immunoassay and chemistry modules. AS is fitted with a refrigerated storage module (RSM) for internal quality controls (QC). The objective of this study was to assess the maximum permissible storage time in AS for QCs. Methods: A total of 48 analytes were tested using QC materials: Liquid Assayed Multiqual (MQ), Liquichek Immunology (LI), Liquichek Lipids (LL), and Liquichek Urine Chemistry (UC). The percentage of variation between results (Xt%) was calculated as the difference between the mean value of the triplicate performed at every time point of the study (Xt) and the average of the triplicate performed in the baseline time (Xo). Stability was assessed based on the total change limit (TCL), which combines analytical and biological variation: TCL=±âˆš((1.65 * CVa)2 + (0.5 * CVb)2). Results: A total of 40 of the 48 analytes tested remained stable at the end of the study. In relation to MQ and UC QCs, 32 of the 39 analytes remained stable for the whole study period (15 days) except for alkaline phosphatase, aspartate aminotransferase, calcium, lactate dehydrogenase, and total bilirubin in MQ, and chlorine and glucose in UC. In LI and LL QCs, eight of the nine analytes were stable throughout the 20 days of the study, except transferrin in LI. Conclusions: The Atellica Solution refrigerated storage module is a reliable system for the storage of quality control materials.

Background: Women across the globe are at risk of physical or sexual abuse by an intimate partner or other offender. Violence against women can lead to physical injuries, impaired mental health, and specific chronic diseases. In some cases, such types of violence can even result in disability or death for some victims. Objetive: To identify the factors that cause domestic violence in women of Guanajuato. Material and methods: Prospective, observational, analytical and cross-sectional study. 325 patients of 18 years or older who were literate and visited a third level hospital were included. The Scale of Violence in Couple Relations with a Likert-type response was administered. Data were analyzed by descriptive statistics. Frequencies and percentages of all variables, chi-square test, and bivariate analysis were used. Results: Of 325 women of 36 (30-46) years of age, 214 (65.8%) were married. The majority were high school graduates, 152 (46.8%). 52% of women reported having experienced domestic violence at least once. Knowing the existence of a domestic violence protection law produced an OR 0.34 (0.20-0.57), p-0.001 and knowing the meaning of domestic violence gave an OR 0.35 (0.21-0.58 ), p<0.001. Conclusions: A high percentage of women reported having experienced domestic violence at least once. The determinants of violence were similar in women with and without exposure to it. Protective factors were knowledge of the law and the meaning of domestic violence.

[Home therapeutic adherence of pelvic floor muscle exercises in urinary incontinence]. / Adherencia terapéutica domiciliaria de ejercicios musculares del suelo pélvico en incontinencia urinaria.

Background: Urinary incontinence (UI) is a medical and social problem that has a great impact on the quality of life of women. Pelvic floor muscle strengthening exercises have been shown to be a form of conservative treatment. However, there is still high failure in this treatment. Objective: To analyze the factors associated with low home therapeutic adherence to pelvic floor exercises in patients with UI. Material and methods: An analytical cross-sectional prolective study was carried out in women aged 20-85 years, with UI and under conservative treatment with pelvic floor muscle exercises. They were questioned about their demographic data; the Morisky Green therapeutic adherence questionnaire and the Likert-type satisfaction scale were applied on the results of the questionnaire. Results: 235 women with UI and with a prescription for pelvic floor muscle exercises, with a median of 55 (46-64) years, were analyzed. The lack of adherence to pelvic floor exercises was observed in 130 (55.32%), whose causes were their work (37.69%), forgetfulness (23.08%) and lack of interest (12.08%). The risk factors for non-adherence were having 3 or less children (OR 1.81 [95% CI 1.10-3.23], p = 0.02), and not feeling satisfied with the exercises (OR 6.70 [95% CI 3.75-11.97], p < 0.001. Conclusion: The factors associated with low home therapeutic adherence to pelvic floor exercises in patients with urinary incontinence were having 3 or less children and not being satisfied with the results.

Conclusión: los factores asociados a la baja adherencia terapéutica domiciliaria de los ejercicios del SP en pacientes con IU fueron tener 3 hijos o menos y no sentirse satisfecha con los resultados sobre la mejoría en los síntomas de IU.

[Inflammatory indexes and their association with the severity of preeclampsia]. / Índices inflamatorios y su asociación con la severidad de la preeclampsia.

Background: Recent studies have confirmed the relationship between some inflammatory indexes and preeclampsia (PE); however, they have not been analyzed in PE with and without severity criteria. Objective: To know the association between inflammatory indexes and the severity of PE. Material and methods: Analytical cross-sectional prolective study. Pregnant patients were included, divided into group 1 (PE without severity criteria); group 2 (PE with severity criteria); group 3 (normotensive pregnant women). Records were reviewed and inflammatory indexes [(neutrophil-lymphocyte ratio [NLR], platelet-lymphocyte ratio [PLR], lymphocyte-monocyte ratio [LMR] and systemic immune index [SII]) were calculated. Results: 240 patients were analyzed, 80 per group; age 28 (IQR 27-29) years. A significant difference was observed between group 1, group 2 and group 3, NLR 3.29 (IQR 2.82-3.69), 3.59 (IQR 2.83-4.2) and 3.42 (IQR 3.17-3.92), respectively, p = 0.02; PLR 121.59 (IQR 103.78-132), 108.32 (IQR 92.96-127.43) 136 (IQR 115.18-157.56), respectively, p = 0.01; LMR and SII showed no difference between the groups. LMR made possible to distinguish PE with and without severity criteria, cut-off point of ≥ 3.20, sensitivity 56%, specificity 56%, AUC 0.56, p = 0.01, and cut-off point ≥ 3.24, sensitivity 58%, specificity 58%, AUC 0.57, p = 0.04, respectively; the LMR ≥ 3.24 was associated with PE without severity criteria (OR 2.02 [95%CI 1.08-3.80], p = 0.03). Conclusions: The MLR was the only inflammatory index analyzed that was associated with the presence of PE without severity data. No inflammatory index was associated with PE with severity data.

Introducción: estudios recientes han confirmado la relación que existe entre algunos índices inflamatorios y la preeclampsia (PE); sin embargo, no se han analizado en la PE con y sin criterios de severidad. Objetivo: conocer la asociación entre los índices inflamatorios y la severidad de la PE. Material y métodos: estudio transversal analítico prolectivo. Se incluyeron pacientes embarazadas, distribuidas en PE sin criterios de severidad (grupo 1), PE con criterios de severidad (grupo 2) y normotensión (grupo 3). Se revisaron expedientes y se calcularon los índices inflamatorios (índice neutrófilos linfocitos [INL], plaquetas linfocitos [IPL], linfocito monocito [ILM] e inmunosistémico [IIS]). Resultados: se analizaron 240 pacientes, 80 por grupo; edad de 28 años (RIC 27-29). Se observó diferencia significativa entre grupo 1, grupo 2 y grupo 3, INL 3.29 (RIC 2.82-3.69), 3.59 (RIC 2.83-4.2) y 3.42 (RIC 3.17-3.92), respectivamente, p = 0.02; IPL 121.59 (RIC 103.78-132), 108.32 (RIC 92.96-127.43) 136 (RIC 115.18-157.56), respectivamente, p = 0.01; ILM y ISS no mostraron diferencia entre los grupos. ILM permitió distinguir PE con y sin criterios de severidad, punto de corte ≥ 3.20, sensibilidad 56%, especificidad 56%, AUC 0.56, p = 0.01, y, punto de corte ≥ 3.24, sensibilidad 58%, especificidad 58%, AUC 0.57, p = 0.04, respectivamente; el ILM ≥ 3.24 se asoció con PE sin criterios de severidad (RM 2.02 [IC 95% 1.08-3.80], p = 0.03). Conclusiones: el ILM fue el único índice inflamatorio analizado que se asoció con la presencia de PE sin criterios de severidad. Ningún índice inflamatorio se asoció con la PE con datos de severidad.

[Association of the Pediatric Appendicitis Score with hospital stay and postoperative complications]. / Asociación de la Escala pediátrica de apendicitis con la estancia hospitalaria y las complicaciones postoperatorias.

Background: Acute appendicitis (AA) is the most common surgical emergency in children. Assessment scales improve the timely detection of cases. Objective: To evaluate the association of the Pediatric Appendicitis Scale (PAS) with hospital stay (HS) and postoperative complications of appendectomy. Material and methods: Observational, analytical, longitudinal and retrolective study. Patients from 2 months to 15 years of age, without comorbidities, who underwent appendectomy for complicated (CAA) and uncomplicated (UCAA) acute appendicitis were included. PAS score prior to an appendectomy was obtained, and the time of HS and postoperative complications were evaluated. Results: 64 patients were evaluated, age 8 (IQR 8-12) years, PAS score 6 (IQR 4-8). The time from the onset of symptoms to the request for care in the emergency department was shorter (p < 0.0001) and the total neutrophil count was higher (p = 0.001) in the CAA group. No difference was shown in the PAS score between patients with CAA and UCAA (6 [4-7] vs. 7 [4-8], p = 0.087]. A PAS score ≥ 7 was associated with an increased risk of prolonged HE (p = 0.007), but was not associated with postoperative complications. The PAS score alongside the time elapsed from the onset of symptoms until the assistance in the Pediatric Emergency Department, were associated with an increased risk of prolonged HE (R2 = 0.2246, p = 0.003). Conclusions: A PAS score ≥ 7 is associated with prolonged HS, likewise, the PAS score alongside the time elapsed between the onset of symptoms and assistance in emergency care is associated with prolonged HS.

Introducción: la apendicitis aguda (AA) es la patología quirúrgica de urgencia más común en niños. Las escalas de valoración mejoran la detección oportuna de casos. Objetivo: evaluar la asociación de la Escala pediátrica de apendicitis (PAS) con la estancia hospitalaria (EH) y las complicaciones postoperatorias de apendicectomía. Material y métodos: estudio observacional, analítico, longitudinal y retrolectivo. Se incluyeron pacientes de 2 meses a 15 años, sin comorbilidades, intervenidos por apendicectomía por apendicitis aguda complicada (AAC) y no complicada (AANC). Se obtuvo el puntaje PAS previo a apendicectomía y se evaluó la EH y complicaciones postoperatorias. Resultados: se evaluaron 64 pacientes, edad 8 (RIC 8-12) años, puntaje de PAS 6 (RIC 4-8). El tiempo desde el inicio de los síntomas hasta la atención en urgencias fue menor (p < 0.0001) y la cuenta de neutrófilos totales fue mayor (p = 0.001) en el Grupo de AAC. No hubo diferencia en el puntaje PAS entre pacientes con AAC y AANC (6 [4-7] frente a 7 [4-8], p = 0.087). El puntaje PAS ≥ 7 se asoció con incremento del riesgo de EH prolongada (p = 0.007), pero no con complicaciones postoperatorias. El puntaje PAS en conjunto con el tiempo transcurrido desde el inicio de los síntomas hasta la atención en Urgencias Pediátricas se asoció a incremento del riesgo de EH prolongada (R2 = 0.2246, p = 0.003). Conclusiones: el puntaje PAS ≥ 7 se asocia con EH prolongada, y el puntaje PAS en conjunto con el tiempo transcurrido entre el inicio de síntomas y la atención en urgencias se asocia a EH prolongada.

[Comparison of unfavorable perinatal outcomes in primiparous adolescents and adults]. / Comparación de resultados perinatales desfavorables en primigestas adolescentes y adultas.

Background: Adolescent pregnancy may be associated with medical complications related to the biological immaturity of the mother, and adult primiparous mothers may present perinatal outcomes associated with pre-existing age-related chronic changes. Objective: To compare unfavorable perinatal outcomes in adolescent and adult primiparous women. Material and methods: Observational, cross-sectional, retrospective and analytical study. Records of adolescent women from 12-19 years and adult women from 20-40 years in their first pregnancy, with a gestation of more than 20 weeks, who entered the Obstetrics Area of a third level hospital for pregnancy resolution were included. Perinatal outcomes were compared using chi-squared, Fisher's exact test, or Mann-Whitney U test. Results: 220 records of primiparous women, 110 adolescents aged 18 (16-19) and 110 adults aged 24 (21-25) were included. Adolescent mothers presented as unfavorable perinatal outcomes newborns (NB) small-for-gestational-age (SGA): odds ratio (OR) 2.95 (95%CI 1.10-7.85), p = 0.04. Adult pregnant women presented more comorbidities (gestational hypertension [11.82 vs. 3.64%] and preeclampsia [10.91 vs. 4.55%], gestational diabetes [6.36 vs. 0.91%], [p = 0.006]) that were associated with prematurity (p = 0.018) and with hospitalization in the NB (p = 0.008). Conclusions: Adolescent mothers presented twice more SGA NB. Prematurity and hospitalization of the NB was associated with the presence of comorbidities in adult mothers.

Introducción: el embarazo en la adolescencia puede estar asociado a complicaciones médicas relacionadas con la inmadurez biológica de la madre y las madres primigestas adultas pueden presentar resultados perinatales asociados a alteraciones crónicas preexistentes relacionadas con la edad. Objetivo: comparar los resultados perinatales desfavorables en primigestas adolescentes y adultas. Material y métodos: estudio observacional, transversal, retrospectivo y analítico. Se incluyeron expedientes de mujeres adolescentes de 12-19 años de edad y mujeres adultas de 20-40 años primigestas, con gestación mayor de 20 semanas, que ingresaron al área de Obstetricia de un hospital de tercer nivel para resolución del embarazo. Los resultados perinatales se compararon con chi cuadrada, prueba exacta de Fisher o U de Mann-Whitney. Resultados: se incluyeron 220 expedientes de mujeres primigestas, 110 adolescentes de 18 (16-19) años y 110 adultas de 24 (21-25) años. Las madres adolescentes presentaron como resultados perinatales desfavorables a recién nacidos (RN) con peso bajo para edad gestacional (PBEG): razón de momios (RM) 2.95 (IC 95% 1.10-7.85), p = 0.04. Las embarazadas adultas presentaron más comorbilidades (hipertensión gestacional [11.82 frente a 3.64%] y preeclampsia [10.91 frente a 4.55%], diabetes gestacional [6.36 frente a 0.91%], [p = 0.006]) que se asociaron con prematurez (p = 0.018) y con la hospitalización en el RN (p = 0.008). Conclusiones: las madres adolescentes presentaron dos veces más RN con PBEG. La prematurez y la hospitalizacion del RN se asoció a la presencia de comorbilidades de las madres adultas.

[Inflammatory indexes during remission induction of pediatric acute leukemia]. / Índices inflamatorios durante la inducción a la remisión de leucemia aguda pediátrica.

Background: Inflammatory indexes can reflect the severity of serious diseases such as acute leukemia (AL), which is why they can predict mortality. Objective: To evaluate the prognostic value of mortality of inflammatory indexes during the remission induction stage in patients with pediatric AL. Material and methods: Observational, longitudinal, analytical and retrolective study. Patients aged 0 to 17 years, with a recent and confirmed diagnosis of AL, who had basal (at diagnosis, before the start of treatment) and final (at the end of remission induction, or, in the cases of death, during the period prior to this outcome) complete blood count were included. Results: We included 78 patients, 67 with acute lymphoblastic leukemia (ALL), and 11 with acute myeloblastic leukemia (AML), with 11 and 2 deaths, respectively. Regarding ALL, no index showed significant cut-off points to distinguish deaths. Concerning AML, the indices whose cut-off points distinguished the patients who died in the basal measurement, were the monocyte-lymphocyte ratio (MLR) ≥ 3.11 (sensitivity [Se] 100%, specificity [Sp] 66.67%, AUC 0.8333, p 0.03), and, at the final measurement, the neutrophil-lymphocyte ratio (NLR) ≥ 1.30 and MLR ≥ 0.57 (both with Se 100% and Sp 88.89%, AUC 1.0, p < 0.00001) and systemic immune index (SII) ≥ 246612 (Se 100%, Sp 88.89%, AUC 0.9444, p < 0.0001). With bivariate analysis, only the latter demonstrated an increase in the risk of mortality (p = 0.02). Conclusions: The basal MLR and the final NLR, MLR and SII are prognostic inflammatory indices of mortality in patients with AML undergoing remission induction.

Introducción: los índices inflamatorios pueden reflejar la severidad de padecimientos graves como la leucemia aguda (LA), con lo que pueden predecir la mortalidad. Objetivo: evaluar el valor pronóstico de mortalidad de los índices inflamatorios durante la etapa de inducción a la remisión en pacientes con LA pediátrica. Material y métodos: estudio observacional, longitudinal, analítico y retrolectivo. Se incluyeron pacientes de 0 a 17 años, con diagnóstico reciente y confirmado de LA, que contaron con citometría hemática basal (al diagnóstico, antes del inicio de tratamiento) y final (al término de la inducción a la remisión o en los casos de defunción, en el periodo previo a este desenlace). Resultados: incluimos 78 pacientes, 67 con leucemia linfoblástica aguda (LLA) y 11 con leucemia mieloblástica aguda (LMA), con 11 y 2 defunciones, respectivamente. En la LLA ningún índice mostró puntos de corte significativos para distinguir muertes. En la LMA, los índices cuyos puntos de corte distinguieron a los pacientes que fallecieron en la medición basal fueron el índice monocito linfocito (IML) ≥ 3.11 (sensibilidad [S] 100%, especificidad [E] 66.67%, AUC 0.8333, p 0.03) y en la medición final, el índice neutrófilo linfocito (INL) ≥ 1.30 y el IML ≥ 0.57 (ambos con S 100% y E 88.89%, AUC 1.0, p < 0.00001) y el índice inmunosistémico (IIS) ≥ 246612 (S 100%, E 88.89%, AUC 0.9444, p < 0.0001). Con análisis bivariado solo este último mostró incremento del riesgo de mortalidad (p = 0.02). Conclusiones: el IML basal y el INL, IML e IIS finales son índices inflamatorios pronósticos de mortalidad en pacientes con LMA en inducción a la remisión.
