X-Linked hypophosphatemia. Data from a Spanish adult population cohort.

BACKGROUND: X-linked hypophosphatemia (XLH) represents the most prevalent cause of hereditary hypophosphatemia. X-linked hypophosphatemia causes an elevation of fibroblast growth factor 23 (FGF23), a hormone responsible for inducing hyperphosphaturia, and reduced active vitamin D synthesis. Challenges in diagnosis and the absence of well-defined clinical guidelines have resulted in higher rates of late diagnoses. While numerous reports focus on pediatric X-linked hypophosphatemia patients, studies in adults are limited. METHODS: Multicenter, cross-sectional, observational study of a cohort of adult patients diagnosed with X-linked hypophosphatemia. The study identified demographic, clinical, genetic, laboratory variables, treatments used, comorbidities, and complications. RESULTS: Twenty patients diagnosed with X-linked hypophosphatemia were collected. The median age at diagnosis was 11 (1-56) years and at data collection was 44 (21-68) years. Fifty percent of cases were diagnosed in adulthood. Main clinical manifestation was osteoarticular pain, in 75% of cases, and no relation to age at diagnosis, height, phosphorus, or parathyroid hormone (PTH) levels was observed (p > 0.05). Lower limb deformities were associated with reduced stature and earlier diagnosis (p < 0.05). Sixty percent of patients reported pain requiring chronic medication and no significant correlation was found with other variables. Anxiety and depression were found in an important number of patients. FGF23 levels were not related to any of the clinical variables studied (p > 0.05). DISCUSSION: This is the largest study on adult patients with X-linked hypophosphatemia in southern Europe. It may offer valuable insights into the natural progression and course of the condition in adults, which can aid in better clinical management.

Metabolomics of Plasma in XLH Patients with Arterial Hypertension: New Insights into the Underlying Mechanisms.

X-linked hypophosphatemia (XLH) is a rare genetic disorder that increases fibroblast growth factor 23 (FGF23). XLH patients have an elevated risk of early-onset hypertension. The precise factors contributing to hypertension in XLH patients have yet to be identified. A multicenter cross-sectional study of adult patients diagnosed with XLH. Metabolomic analysis was performed using ultra-performance liquid chromatography (UPLC) coupled to a high-resolution mass spectrometer. Twenty subjects were included, of which nine (45%) had hypertension. The median age was 44 years. Out of the total, seven (35%) subjects had a family history of hypertension. No statistically significant differences were found between both groups for nephrocalcinosis or hyperparathyroidism. Those with hypertension exhibited significantly higher levels of creatinine (1.08 ± 0.31 mg/dL vs. 0.78 ± 0.19 mg/dL; p = 0.01) and LDL-C (133.33 ± 21.92 mg/dL vs. 107.27 ± 20.12 mg/dL, p = 0.01). A total of 106 metabolites were identified. Acetylcarnitine (p = 0.03), pyruvate p = (0.04), ethanolamine (p = 0.03), and butyric acid (p = 0.001) were significantly different between both groups. This study is the first to examine the metabolomics of hypertension in patients with XLH. We have identified significant changes in specific metabolites that shed new light on the potential mechanisms of hypertension in XLH patients. These findings could lead to new studies identifying associated biomarkers and developing new diagnostic approaches for XLH patients.

Using Principles of Digital Development for a Smartphone App to Support Data Collection in Patients With Acute Myocardial Infarction and Physical Activity Intolerance: Case Study.

BACKGROUND: Advances in health have highlighted the need to implement technologies as a fundamental part of the diagnosis, treatment, and recovery of patients at risk of or with health alterations. For this purpose, digital platforms have demonstrated their applicability in the identification of care needs. Nursing is a fundamental component in the care of patients with cardiovascular disorders and plays a crucial role in diagnosing human responses to these health conditions. Consequently, the validation of nursing diagnoses through ongoing research processes has become a necessity that can significantly impact both patients and health care professionals. OBJECTIVE: We aimed to describe the process of developing a mobile app to validate the nursing diagnosis "intolerance to physical activity" in patients with acute myocardial infarction. METHODS: We describe the development and pilot-testing of a mobile system to support data collection for validating the nursing diagnosis of activity intolerance. This was a descriptive study conducted with 11 adults (aged ≥18 years) who attended a health institution for highly complex needs with a suspected diagnosis of coronary syndrome between August and September 2019 in Floridablanca, Colombia. An app for the clinical validation of activity intolerance (North American Nursing Diagnosis Association [NANDA] code 00092) in patients with acute coronary syndrome was developed in two steps: (1) operationalization of the nursing diagnosis and (2) the app development process, which included an evaluation of the initial requirements, development and digitization of the forms, and a pilot test. The agreement level between the 2 evaluating nurses was evaluated with the κ index. RESULTS: We developed a form that included sociodemographic data, hospital admission data, medical history, current pharmacological treatment, and thrombolysis in myocardial infarction risk score (TIMI-RS) and GRACE (Global Registry of Acute Coronary Events) scores. To identify the defining characteristics, we included official guidelines, physiological measurements, and scales such as the Piper fatigue scale and Borg scale. Participants in the pilot test (n=11) had an average age of 63.2 (SD 4.0) years and were 82% (9/11) men; 18% (2/11) had incomplete primary schooling. The agreement between the evaluators was approximately 80% for most of the defining characteristics. The most prevalent characteristics were exercise discomfort (10/11, 91%), weakness (7/11, 64%), dyspnea (3/11, 27%), abnormal heart rate in response to exercise (2/10, 20%), electrocardiogram abnormalities (1/10, 9%), and abnormal blood pressure in response to activity (1/10, 10%). CONCLUSIONS: We developed a mobile app for validating the diagnosis of "activity intolerance." Its use will guarantee not only optimal data collection, minimizing errors to perform validation, but will also allow the identification of individual care needs.

The Factors associated with the onset of sexual activity in adolescents: Analytic cross-sectional

Introduction: Different physical, social, affective, and sexual changes take place during adolescence, such as the sexual debut. Objective: To explore the factors associated with the onset of sexual activity in adolescents attending school (12­16 years) in Bucaramanga. Materials and Methods: This analytical cross-sectional study included 440 adolescents from a public school. An instrument developed by Latin American Center for Perinatology - History of Adolescents was applied, and descriptive and bivariate analyses were conducted using a binomial regression model adjusted by age and sex, with sexual activity onset as the outcome and possible associated factors as exposures. Results: The prevalence of the onset of sexual activity was 22.27% (95% CI: 18.56­26.46). Factors associated with greater prevalence of sexual activity onset were having a criminal record and partner PR=3.24, (95%CI: 2.60­4.05) and PR=2.00, (95%CI: 1.42­2.82), respectively. Male gender PR=1.19, (95% CI: 0.84­1.67), using tobacco PR=1.23 (95% CI: 0.73­2.06), alcohol consumption PR=1.23, (95% CI: 0.73­2.06), and other psychoactive substance use PR=1.78, (95% CI: 0.99­3.19) were risk factors; meanwhile, socializing with friends was a protective factor PR=0.27, (95% CI: 0.20­0.36). Discussion: Follow-up by parents and school support decrease the risk of adolescent sexual activity onset. Furthermore, interventions in the family and school settings are important. Conclusion: There are conditions that could promote the beginning of sexual activity in adolescence such as being male, having a partner, having a criminal record, smoking, and consuming alcohol or other substances could promote adolescent sexual activity onset, while socializing with friends was found to be a protective factor.

Corrélation of EQ-5D and mRS in ischémie stroke: a multicenter cross-sectional study

Introduction: Assessing Health-Related Quality of Life (HRQOL), in addition to evaluating functional status in stroke patients could complement clinician practice. Objective: To assess HRQOL, applying EuroQol-5-dimensions (EQ-5D) in Colombian patients with stroke and correlating its results with the modified Rankin Scale (mRS). Methods: Analytical cross-sectional study in a cohort of ischemic stroke patients in Colombia at three months as a median follow-up (Q1: 1- Q3:3) after their event. We correlated EQ-5D domains, EQ-5D index, mRS with EQ-5D VAS score. We generated a simple linear regression robust model to evaluate the variability between using r2. Results: A total of 91 patients completed the EQ-5D questionnaire, with a mean age of 71.2 years; 59.3% were male. We identified an inverse correlation between EQ-5D VAS and EQ-5D domains with the highest for mobility (rs = -0.69) and the lowest for pain/discomfort (rs -0.52, p<0.001). The r2 ranged from 0.25 (pain/discomfort) to 0.47 (EQ-5D index). Patients with mRS ≥ 3 significantly reduced their EQ-5D VAS score by 25.64 points (95% CI -33.04, -18.24). Variability in EQ-5D VAS scores occurred by EQ-5D index (47%) and by mRS (34%). Conclusions: The correlation between EQ-5D and mRS was favorable. Although EQ-5D and mRS evaluated different spheres on stroke patients, applying the EQ-5D instrument in real-world clinical settings might contribute multidimensional information on how life is affected after a stroke. This kind of information serves to orientate rehabilitation strategies on specific domains such as depression, self-care, anxiety, and pain. This is especially relevant for patients with disabilities (mRS ≥ 3).

Introducción: La evaluación de la Calidad de Vida Relacionada con la Salud (CVRS) y el estado funcional de pacientes con Ataque Cerebrovascular (ACV), podría complementar la práctica clínica. Objetivo: Evaluar la CVRS, aplicando EuroQol-5-dimensiones (EQ-5D) en pacientes colombianos con ACV y correlacionar sus resultados con la escala de Rankin Modificada (mRS). Métodos: Estudio de corte transversal analítico anidado a una cohorte de pacientes con ACV isquémico en Colombia con mediana de 3 meses de seguimiento (Q1: 1- Q3:3) post-ictus. Correlacionamos los dominios del EQ-5D, índice EQ-5D y mRS con la puntuación de EQ-5D VAS. Generamos un modelo de regresión lineal simple para evaluar la variabilidad usando r2. Resultados: Un total de 91 pacientes con una edad media 71,2 años; 59,3 % hombres. Se encontró correlación inversa entre los dominios EQ-5D, mayor para movilidad (rs = -0,69) y menor para dolor/malestar (rs -0,52, p < 0,001). El r2 osciló entre 0,25 (dolor/malestar) y 0,47 (índice EQ-5D). Los pacientes con mRS ≥ 3 redujeron significativamente su puntuación EQ-5D VAS en 25,64 puntos (IC 95%: -33,04; -18,24). La variabilidad en las puntuaciones EQ-5D VAS se produjo por el índice EQ-5D (47 %) y por mRS (34 %). Conclusiones: La correlación entre EQ-5D y mRS fue favorable. Aunque EQ-5D y mRS evalúan diferentes esferas en los pacientes con ACV, la aplicación del EQ-5D en podría aportar información multidimensional sobre cómo se afecta la vida después de un ictus, así como orientar estrategias de rehabilitación en esferas como depresión, autocuidado, ansiedad y dolor; especialmente relevante para pacientes con discapacidades (mRS ≥ 3).

Acquired perforating dermatosis in patients on peritoneal dialysis: a report of 3 cases.

Background: Acquired perforating dermatosis (APD) is a heterogeneous group of unfrequented diseases (2.5 cases for 100,000 habitants) associated with multiple pathologies like end-stage renal disease and other concomitant conditions such as diabetes mellitus (DM). Case Description: We described 3 cases of APD in patients on peritoneal dialysis (PD), one of them with a giant variant of reactive perforating collagenosis (RPC). The first case is a 28-year-old man with chronic kidney disease on PD and a lousy control of disturbances of calcium and phosphorus metabolism that develops an APD. The second case is a 44-year-old man with DM, chronic kidney disease (CKD) on PD, and poor control of disturbances of calcium and phosphorus metabolism that develops an RPC. The third case is a 58-year-old man with DM, rheumatoid arthritis, hypothyroidism, CKD and bad control of calcium and phosphorus metabolism that develops a giant variant of RPC with poor evolution. Conclusions: CKD and concomitant conditions such as DM present an increased risk of developing APD. Poor control of calcium and phosphorus metabolism is frequently found in patients with CKD and seems to be related to the development of APD in our cases. With the description of these cases, we want to emphasize the importance of knowing this rare disease, in order to promptly refer to Dermatology and start treatment.

Role of the Nephrologist in Non-Kidney Solid Organ Transplant (NKSOT).

BACKGROUND: Chronic kidney disease (CKD) is a common complication of a non-kidney solid organ transplant (NKSOT). Identifying predisposing factors is crucial for an early approach and correct referral to nephrology. METHODS: This is a single-center retrospective observational study of a cohort of CKD patients under follow-up in the Nephrology Department between 2010 to 2020. Statistical analysis was performed between all the risk factors and four dependent variables: end-stage renal disease (ESKD); increased serum creatinine ≥50%; renal replacement therapy (RRT); and death in the pre-transplant, peri-transplant, and post-transplant periods. RESULTS: 74 patients were studied (7 heart transplants, 34 liver transplants, and 33 lung transplants). Patients who were not followed-up by a nephrologist in the pre-transplant (p < 0.027) or peri-transplant (p < 0.046) periods and those who had the longest time until an outpatient clinic follow-up (HR 1.032) were associated with a higher risk of creatinine increase ≥50%. Receiving a lung transplant conferred a higher risk than a liver or heart transplant for developing a creatinine increase ≥50% and ESKD. Peri-transplant mechanical ventilation, peri-transplant and post-transplant anticalcineurin overdose, nephrotoxicity, and the number of hospital admissions were significantly associated with a creatinine increase ≥50% and developing ESKD. CONCLUSIONS: Early and close follow-up by a nephrologist was associated with a decrease in the worsening of renal function.

Desenlace funcional asociado al ataque cerebrovascular menor en una población colombiana: un estudio de cohorte / Functional outcome associated with minor stroke in a colombian population: a cohort study

RESUMEN INTRODUCCIÓN. El ACV menor hace referencia a un evento isquémico que cursa con síntomas leves. Se ha señalado que estos pacientes pueden presentar un desenlace clínico desfavorable. OBJETIVO: Evaluar el desenlace funcional a 90 días de pacientes con ACV isquémico menor, atendidos en dos hospitales de Bucaramanga, Colombia, entre los años 2015 y 2017. MÉTODOS. Estudio de cohorte en pacientes con ACV isquémico agudo y un puntaje NIHSS ≤ 5 puntos. Un desenlace clínico desfavorable a 90 días de seguimiento fue medido como un puntaje Rankin-m ≥ 3 puntos. Se realizó un análisis bivariado a través de modelos de regresión binomial simple y ajustado por edad y sexo. Un valor p <0,05 fue considerado estadísticamente significativo. RESULTADOS. Se incluyeron 90 pacientes (edad de 66,6± 13,5 años, 54,4% (n=49) de sexo masculino). El 36,5% (n=23) de los pacientes presentó un puntaje Rankin-m de 3 a 6 puntos. El antecedente de diabetes mellitus (RR: 2,50 IC 95%:1,33-4,70) y un Rankin-m previo de 2 (RR 2,12 IC 95%:1,39-3,24) fueron variables independientemente asociadas a discapacidad significativa. CONCLUSIÓN. Un estado funcional previamente comprometido, sumado a la disfunción endotelial que genera la diabetes mellitus, contribuye a un desenlace desfavorable en los pacientes con ACV menor.

ABSTRACT INTRODUCTION. Minor stroke refers to an ischemic vascular event that start with discrete symptoms. It has been suggested that these patients may have an unfavorable clinical outcome. AIM. To evaluate the functional outcome at 90 days in patients with minor ischemic stroke in two hospitals in Bucaramanga, between 2015 and 2017. METHODS. Cohort study in patients with acute ischemic stroke and NIHSS ≤ 5 points. An unfavorable clinical outcome was measured according to the modified Rankin Scale as ≥ 3 points. A bivariate analysis was performed through simple binomial regression models adjusted for age and sex. A p-value <0.05 was considered statistically significant. RESULTS. 90 patients were included (Aged 66.6 ± 13.5 years, 49 males (54%); 23 (36,5%) presented a modified Rankin score of 3-6 points. A history of diabetes (RR: 2.50 CI 95%: 1.33-4.70) and a modified Rankin score of 2 points prior to the event (RR 2.12 CI 95%: 1.39-3.24) were independently associated with significant disability CONCLUSION. A previously compromised functional state, added to the endothelial dysfunction generated by diabetes mellitus, contribute significantly to an unfavorable outcome in patients with minor stroke.

The metabolomic differential plasma profile between dialysates. Pursuing to understand the mechanisms of citrate dialysate clinical benefits.

Background: Currently, bicarbonate-based dialysate needs a buffer to prevent precipitation of bicarbonate salts with the bivalent cations, and acetate at 3-4 mmol/L is the most used. However, citrate is being postulated as a preferred option because of its association with better clinical results by poorly understood mechanisms. In that sense, this hypothesis-generating study aims to identify potential metabolites that could biologically explain these improvements found in patients using citrate dialysate. Methods: A unicentric, cross-over, prospective untargeted metabolomics study was designed to analyze the differences between two dialysates only differing in their buffer, one containing 4 mmol/L of acetate (AD) and the other 1 mmol/L of citrate (CD). Blood samples were collected in four moments (i.e., pre-, mid-, post-, and 30-min-post-dialysis) and analyzed in an untargeted metabolomics approach based on UPLC-Q-ToF mass spectrometry. Results: The 31 most discriminant metabolomic variables from the plasma samples of the 21 participants screened by their potential clinical implications show that, after dialysis with CD, some uremic toxins appear to be better cleared, the lysine degradation pathway is affected, and branched-chain amino acids post-dialysis levels are 9-10 times higher than with AD; and, on its part, dialysis with AD affects acylcarnitine clearance. Conclusion: Although most metabolic changes seen in this study could be attributable to the dialysis treatment itself, this study successfully identifies some metabolic variables that differ between CD and AD, which raise new hypotheses that may unveil the mechanisms involved in the clinical improvements observed with citrate in future research.

Entrenamiento de atención focalizada para disminuir la ansiedad en pacientes candidatos a craneotomía.

BACKGROUND: The focused attention training has been used in pre surgery patients because of the benefits of its use decrease of psychological symptoms like anxiety, eases the post operatory period and recovery. Also, there are favorable changes in a psychological level as well as pain healing. OBJECTIVE: Show that the focused attention training is effective in patients who are candidates to a craniotomy. METHOD: The study includes 11 participants in an age of 29 to 60 age from the Hospital de Especialidades del Centro Médico Nacional Siglo XXI, from May to September 2021. The Hospital Anxiety and Depression Scale (HADS) was applied pre, post and follow-up, to search anxiety symptoms and the focused attention training was used in the 11 patients. RESULTS: The data was analyzed and checked with the Friedman test, for not parametric data and to identify differences in anxiety levels. It was observed that there are differences (p < 0.05) in both anxiety and depression. CONCLUSIONS: Anxiety decreased significantly before and after the focused attention training, the follow-up was kept the same way for 40 days; which means the training helped the patient to decrease anxiety.

ANTECEDENTES: El entrenamiento de atención focalizada se ha utilizado en pacientes prequirúrgicos por los beneficios que conlleva: disminuye los síntomas psicológicos como ansiedad, facilita el periodo posoperatorio y la recuperación, cambios favorables a nivel fisiológico y reducción del dolor, entre otros. OBJETIVO: Demostrar la eficacia del entrenamiento de atención focalizada en pacientes candidatos a craneotomía. MÉTODO: El estudio incluyó 11 participantes de entre 29 y 60 años de edad del Hospital de Especialidades del Centro Médico Nacional Siglo XXI, de mayo a septiembre de 2021. Se aplicó la Hospital Anxiety and Depression Scale (HADS) antes, después de la intervención y a los 40 días para investigar síntomas de ansiedad, y se utilizó el entrenamiento de atención focalizada en los 11 participantes. RESULTADOS: Se analizaron los datos con la prueba de Friedman para datos no paramétricos con el fin de identificar diferencias en los niveles de ansiedad. Se observó que sí hay diferencias (p < 0.05) tanto en ansiedad como en depresión. CONCLUSIONES: La ansiedad disminuyó significativamente entre las mediciones antes y después de la intervención. La medición posterior continuó de la misma manera durante los 40 días, lo que significa que el entrenamiento ayudó al paciente a disminuir la ansiedad.

Impact of Acetate versus Citrate Dialysates on Intermediary Metabolism-A Targeted Metabolomics Approach.

Acetate is widely used as a dialysate buffer to avoid the precipitation of bicarbonate salts. However, even at low concentrations that wouldn't surpass the metabolic capacity of the Krebs tricarboxylic acid (TCA) cycle, other metabolic routes are activated, leading to undesirable clinical consequences by poorly understood mechanisms. This study aims to add information that could biologically explain the clinical improvements found in patients using citrate dialysate. A unicentric, cross-over, prospective targeted metabolomics study was designed to analyze the differences between two dialysates, one containing 4 mmol/L of acetate (AD) and the other 1 mmol/L of citrate (CD). Fifteen metabolites were studied to investigate changes induced in the TCA cycle, glycolysis, anaerobic metabolism, ketone bodies, and triglyceride and aminoacidic metabolism. Twenty-one patients completed the study. Citrate increased during the dialysis sessions when CD was used, without surpassing normal values. Other differences found in the next TCA cycle steps showed an increased substrate accumulation when using AD. While lactate decreased, pyruvate remained stable, and ketogenesis was boosted during dialysis. Acetylcarnitine and myo-inositol were reduced during dialysis, while glycerol remained constant. Lastly, glutamate and glutarate decreased due to the inhibition of amino acidic degradation. This study raises new hypotheses that need further investigation to understand better the biochemical processes that dialysis and the different dialysate buffers induce in the patient's metabolism.

Lipidic profiles of patients starting peritoneal dialysis suggest an increased cardiovascular risk beyond classical dyslipidemia biomarkers.

Patients on peritoneal dialysis (PD) have an increased risk of cardiovascular disease (CVD) and an atherogenic lipid profile generated by exposure to high glucose dialysis solutions. In the general population, the reduction of classic lipids biomarkers is associated with improved clinical outcomes; however, the same results have not been seen in PD population, a lack of data this study aims to fulfill. Single-center prospective observational study of a cohort of CKD patients who started renal replacement therapy with continuous ambulatory peritoneal dialysis. The differences in the lipid profile and analytical variables before and 6 months after the start of peritoneal dialysis were analyzed. Samples were analyzed on an Ultra-Performance Liquid Chromatography system. Thirty-nine patients were enrolled in this study. Their mean age was 57.9 ± 16.3 years. A total of 157 endogenous lipid species of 11 lipid subclasses were identified. There were significant increases in total free fatty acids (p < 0.05), diacylglycerides (p < 0.01), triacylglycerides, (p < 0.01), phosphatidylcholines (p < 0.01), phosphatidylethanolamines (p < 0.01), ceramides (p < 0.01), sphingomyelins (p < 0.01), and cholesterol esters (p < 0.01) from baseline to 6 months. However, there were no differences in the classical lipid markers, neither lysophosphatidylcholines, monoacylglycerides, and sphingosine levels. 6 months after the start of the technique, PD patients present changes in the lipidomic profile beyond the classic markers of dyslipidemia.

Resultados: foram incluídos 36 artigos com um total de 19.036 pacientes; 50% (n=18) utilizaram o NAS, 27,7%(n=10) utilizaram uma combinação de métodos como NAS, NEMS, TISS-28 ou VACTE, 13,8%(n=5) utilizaram o TISS-28, 5,6% (n=2) utilizaram registros de câmeras de vídeo e 2,7%(n=1) utilizaram o NEMS para quantificar o tempo gasto pela enfermagem no cuidado. Discussão: atualmente não há consenso sobre métodos de mensuração da carga de trabalho em enfermagem, nesse sentido, faz-se necessária a realização de mais estudos de validação e comparação para melhorar o gerenciamento do cuidado de enfermagem em UTI. Conclusão: O instrumento mais utilizado para quantificar a carga de trabalho de enfermagem é o Nursing Activities Score (NAS), outros instrumentos identificados foram: NEMS, TISS-28 e VACTE.

Non-albuminuric Diabetic Kidney Disease Phenotype: Beyond Albuminuria.

Diabetic kidney disease (DKD) is the leading cause of chronic and end-stage kidney disease worldwide. Its pathogenic mechanism is complex, and it can affect the entire structures of the kidneys such as the glomerulus, tubules and interstitium. Currently, the urinary albumin excretion rate and the estimated glomerular filtration rate are widely accepted as diagnostic criteria. However, some studies have reported a different or non-classical clinical course of DKD, with some patients showing declined kidney function with normal levels of albuminuria, known as the 'non-albuminuric DKD' phenotype. The pathogenesis of this phenotype remains unclear, but some clinical and pathological features have been postulated. This review explores the evidence regarding this topic.

Cumplimiento de la lista de verificación de seguridad de la cirugía en un hospital de Santander. Un estudio de corte trasversal / Compliance with the surgical safety checklist in a hospital in Santander. A cross-sectional study

Introducción: La seguridad del paciente constituye una prioridad en la atención en salud, siendo la lista de verificación para la seguridad quirúrgica una de las estrategias implementadas por la OMS. El objetivo fue determinar el nivel de cumplimiento en la aplicación de la lista de verificación de seguridad de la cirugía en personal de sala quirúrgica de una institución pública. Materiales y Métodos: Estudio de corte transversal en 45 miembros del equipo quirúrgico de un hospital, en los cuales se evaluó el cumplimiento a la lista de chequeo de la OMS durante el mes de julio y agosto del año 2018. Resultados: El cumplimiento global fue del 13.3% (n=6), siendo la fase previa a la anestesia la que alcanzó el mayor nivel (55.6%, n=25). El mayor cumplimiento lo registró el personal de instrumentación quirúrgica (100%, n=8), mientras el más bajo el personal de enfermería (25%, n=3), con diferencias estadísticamente significativas (p=0.005). Adicionalmente, se observó una correlación entre los años de trabajo en el servicio y el cumplimiento en fase de transferencia (rho= -0.30, p=0.048). Discusión: El cumplimiento general fue bajo, lo cual corrobora la hipótesis planteada y resulta similar a otros estudios descritos en la literatura. Conclusiones: El cumplimiento general a la lista de chequeo fue muy bajo, con comportamientos diferenciales al ser las instrumentadoras quirúrgicas las que presentaron mayor cumplimiento y el personal de enfermería el menor. El ítem de profilaxis antibiótica el de menor cumplimiento, mientras que la fase previa a la anestesia la de mayor nivel.

Introduction: Patient safety constitutes a priority in health care, being the surgical safety checklist one of the strategies implemented by the WHO. The objective was to determine the level of compliance in the application of the surgical safety checklist in surgical room personnel of a public institution. Materials and Methods: Cross-sectional study in 45 members of the surgical team in a hospital, in which compliance to the WHO checklist was evaluated during July and August 2018. Results: Overall compliance was 13.3% (n=6), with the pre-anesthesia phase reaching the highest level (55.6%, n=25). The highest compliance was recorded by the surgical instrumentation staff (100%, n=8), while the lowest by the nursing staff (25%, n=3), with statistically significant differences (p=0.005). Additionally, a correlation was observed between years of work in the service and compliance in the transfer phase (rho= -0.30, p=0.048). Discussion: Overall compliance was low, which corroborates the stated hypothesis and is similar to other studies described in the literature. Conclusions: The overall compliance to the checklist was very low, with differential behaviors as the surgical instrument technicians showed the highest compliance and the nursing staff the lowest. The antibiotic prophylaxis item was the least compliant, while the pre-anesthesia phase was the most compliant.

Introdução: A segurança do paciente é prioridade na assistência à saúde, sendo o checklist de segurança cirúrgica uma das estratégias implantadas pela OMS. O objetivo foi determinar o nível de conformidade na aplicação da lista de verificação de segurança cirúrgica na equipe de centro cirúrgico de uma instituição pública. Materiais e métodos: Estudo transversal em 45 membros da equipe cirúrgica de um hospital, no qual foi avaliada a conformidade com o checklist da OMS durante os meses de julho e agosto de 2018. Resultados: A adesão geral foi de 13,3%(n=6), sendo a fase anterior à anestesia a que atingiu o nível mais alto (55,6%, n=25). A maior conformidade foi registrada pela equipe de instrumentação cirúrgica (100%, n=8), enquanto a menor foi pela equipe de enfermagem (25%, n=3), com diferenças estatisticamente significativas (p=0,005). Além disso, foi observada correlação entre anos de trabalho no serviço e adesão na fase de transferência (rho = -0,30, p=0,048). Discussão: A adesão geral foi baixa, o que corrobora a hipótese levantada e é semelhante a outros estudos descritos na literatura. Conclusões: O cumprimento geral do checklist foi muito baixo, com comportamentos diferenciados, visto que a instrumentação cirúrgica foi a que mais aderiu e a equipe de enfermagem menos. A profilaxia antibiótica item a de menor complacência, enquanto a fase pré-anestésica a de maior grau.

Importancia del sitio de terminación de la vena cefálica del antebrazo / Importance of the cephalic antebrachial vein termination site

RESUMEN: Las venas superficiales de la fosa cubital se han estudiado con varios fines, venopunciones, cateterismos, fístulas, entre otros. Se han descrito varios patrones venosos en esta región en diferentes poblaciones. En uno de estos la vena cefálica termina en la vena basílica a nivel del antebrazo generando posibles riesgos de lesiones durante la canalización. En el presente estudio se evaluaron 200 miembros superiores de 100 personas colombianas, 50 mujeres y 50 hombres, 70 de ellas nacidas en la ciudad de Bucaramanga y 30 en la ciudad de Villavicencio. Se registró el número de venas cefálicas y su sitio de terminación, en el brazo o antebrazo. El patrón venoso que predominó en ambos miembros superiores fue el tipo I. El patrón IV en el cual la vena cefálica termina en la vena basílica se presentó en 12 casos (6 %) en el miembro superior derecho y en 17 casos (8,5 %) en el miembro superior izquierdo. Se encontró dos venas cefálicas entre el 13 % y 13,5 % dependiendo del lado y tres venas cefálicas entre el 1 % y 2 %. Conocer esta particularidad de los patrones venosos podría disminuir el riesgo de complicaciones durante la venopunción.

SUMMARY: The superficial veins of the ulnar fossa have been studied for various purposes, venipuncture, catheterization, fistulae, among others. Various venous patterns have been described in this region in different populations. In one of these, the cephalic vein ends in the basilic vein at the level of the forearm, generating possible risks of injury during cannulation. In the present study, 200 upper limbs of 100 Colombians, 50 women and 50 men, were evaluated, 70 of them born in the city of Bucaramanga and 30 in the city of Villavicencio. The number of cephalic veins and their termination site, on the arm or forearm, were recorded. The venous pattern that predominated in both upper limbs was type I. Pattern IV in which the cephalic vein ends in the basilic vein occurred in 12 cases (6 %) in the right upper limb and in 17 cases (8.5 %) in the left upper limb. Two cephalic veins were found between 13 % and 13.5 % depending on the side and three cephalic veins between 1 % and 2 %. Knowing this particularity of venous patterns could reduce the risk of complications during venipuncture.

Calidad de vida relacionada con la salud en personas con hipertensión y diabetes mellitus / Quality of life related to health in people with hypertension and diabetes mellitus

OBJETIVO: Determinar los factores sociodemográficos y clínicos asociados a la Calidad de Vida relacionada con la salud (CVRS) en personas con hipertensión arterial y diabetes mellitus tipo 2. MÉTODOS: Estudio analítico de corte transversal en una muestra de 184 usuarios de un programa de control de riesgo cardiovascular en Bucaramanga (Colombia). Se utilizó el instrumento EQ-5D-3L para evaluar la calidad de vida. Un modelo de regresión lineal múltiple fue llevado a cabo usando como desenlace la Escala Visual Análoga y como posibles predictores las dimensiones del EQ-5D, ajustando por edad, sexo, grupo de intervención (variable instrumental) y variables clínicas como la patología de base y el control de la misma. RESULTADOS: La mediana de edad fue 63 años, 73,3% mujeres, 88,0% nivel socioeconómico bajo; mediana de Presión Arterial Sistólica de 130 mmHg (116,0-145,0) y de HbA1c 5,7% (5,4-6,2) en la población general, hallándose diferencias estadísticamente significativas entre los grupos de patología. La mediana de la Escala Visual Análoga fue de 80(Q1:59-Q3:95) puntos, sin diferencias estadísticamente significativas entre los grupos de patología. Manifestar dolor/malestar, tener problemas en las actividades cotidianas y el no control de la hipertensión arterial disminuyó la percepción de la calidad de vida relacionada con la salud, en 7,5, 18,1 y 7,3 puntos, respectivamente. CONCLUSIONES: La CVRS, en general, fue alta. Esta fue mayor en las personas con diabetes mellitus tipo 2. Factores relacionados con la funcionalidad y control de la enfermedad fueron asociados con una menor percepción de la CVRS

OBJECTIVE: To determine the sociodemographic and clinical factors associated with health-related Quality of Life (HRQoL) among people with hypertension and type 2 diabetes mellitus. METHODS: Analytical cross-sectional study in a sample of 184 users of a cardiovascular risk control program in Bucaramanga (Colombia). The EQ-5D-3L instrument was used to assess quality of life. A multiple linear regression model was carried out using the Visual Analog Scale as the outcome and the dimensions of the EQ-5D as possible predictors, adjusting for age, sex, intervention group (instrumental variable), and clinical variables such as the disease and its control. RESULTS: The median of age was 63 years, 73.3% women, 88.0% low socioeconomic level; Median Systolic Blood Pressure of 130 mmHg (116.0-145.0) and HbA1c 5.7% (5.4-6.2) in the general population, showing statistically significant differences between the pathology groups. The median of Visual Analog Scale was 80(Q1: 59-Q3: 95) points, with no statistically significant differences between the pathology groups. Manifesting pain/discomfort, problems with usual activities and lack of hypertension control decreased the perception of HRQoL, by 7.5, 18.1 and 7.3 points, respectively. CONCLUSIONS: The HRQoL in general was high. It was higher among people with type 2 diabetes mellitus. Factors related to the functionality and control of the disease were associated with a lower perception HRQoL

Raquitismo hipofosfatémico ligado al cromosoma X: diagnóstico en la edad adulta y forma paucisintomática / X-linked hypophosphatemic rickets: Diagnosis in adult and paucisymptomatic form

El raquitismo hipofosfatémico ligado al cromosoma X (XLH) es la principal forma de raquitismo hereditario causada por la mutación del gen PHEX y que se manifiesta principalmente en la infancia. Clínicamente cursa con retraso en el crecimiento y deformidades óseas, sin embargo, existen formas de presentación atípicas que dificultan el diagnóstico. Presentamos un caso de XLH con diagnóstico tardío y forma paucisintomática que presenta múltiples fracturas y gran afectación en su calidad de vida, en tratamiento con la terapia clásica para esta enfermedad.(AU)

X-linked hypophosphataemic rickets (XLH) is the main form of hereditary rickets caused by mutation of the PHEX gene and occurs mainly in childhood. Clinically, it causes growth retardation and bone deformities; however, there are atypical forms of presentation that make diagnosis difficult. We present a case of XLH of late diagnosis and paucisymptomatic form with multiple fractures and greatly affecting quality of life, under treatment with traditional therapy for this disease.(AU)
