RESUMO

Background: In Mexico less than half of the treated hypertensive patients reach blood pressure (BP) targets. Most hypertensive individuals rely on the standard medical care (SMC) to achieve the BP control goals; however, the efficacy of BP telemonitoring (BPT) to achieve BP targets has been poorly studied. Aim: To compare the efficacy of BPT versus SMC to achieve BP goals in patients with uncontrolled hypertension. Methods: A two-arm, open-label clinical trial was conducted in patients ≥18 years with uncontrolled hypertension. The participants were randomized to 2 arms (BPT vs SMC) and followed for 12 weeks. For the statistical analysis, the chi-squared test and covariance were used. Results: One hundred and seventy-eight participants were included, BPT (n = 94) and SMC (n = 84), after 12 weeks of follow up, we observed a baseline-adjusted reduction in systolic BP with both BPT (-13.5 [1.3] mmHg) and the SMC (-5.9 [1.4] mmHg; p < 0.001) but a greater decrease with BPT (p < 0.001). Likewise, we found a baseline-adjusted reduction of diastolic BP with BPT (-6.9 [0.9] mmHg) and SMC (-2.7 [0.9] mmHg) (p = 0.007) with a more significant percentage change from baseline with BPT (-6.8% [1.0] vs 2.5% [1.1]; p = 0.007). In the BPT arm, a larger proportion of patients achieved the BP target versus SMC (30.5% vs 12.8%; p = 0.005). Conclusion: BPT showed a greater proportion of patients achieving office BP control goals (<140/90 mmHg), compared to standard medical care.

RESUMO

Resumen La enfermedad renal crónica (ERC) es de alta prevalencia en América Latina y en todo el mundo. Se estima que entre 10 y 20% de la población adulta es portadora de ERC y su prevalencia va en aumento. La ERC progresa en forma silenciosa. Su diagnóstico temprano y oportuno permite iniciar un tratamiento efectivo, en la mayoría de los casos, para detener la enfermedad. Desde hace mucho tiempo, el análisis de la creatininemia es la principal prueba utilizada para valorar la función renal, pero su confiabilidad es limitada. De acuerdo con las recomendaciones de las GUIAS KDOQI del año 2002 la tasa de filtración glomerular estimada (TFGe) obtenida a través de fórmulas, se estableció como una de las herramientas principales para detectar la enfermedad renal de manera precoz, ya que alerta de forma precisa al médico y al equipo de salud sobre el nivel de función renal del paciente. La detección de una TFGe disminuida (menor de 60 mL/min/1,73 m2) es clínicamente relevante, ya que permite establecer el diagnóstico de enfermedad renal en adultos. En el año 2022, en una encuesta realizada por SLANH y COLABIOCLI dirigida a los laboratorios de análisis clínicos de América Latina (n: 237), el 49% de los mismos no informaban la TFGe rutinariamente. En base a esta realidad SLANH y COLABIOCLI elaboraron estas recomendaciones de consenso en referencia al uso de la TFGe.

Abstract Chronic kidney disease (CKD) has a high prevalence worldwide and in Latin America (10 to 20% of the adult population) and is increasing. CKD progresses silently. Opportune diagnosis and treatment are effective in most cases to improve outcomes. Serum creatinine was the main test to assess kidney function, but its reliability is limited. Through the KDOQI Guidelines 2002, the estimated glomerular filtration rate (eGFR) obtained from equations was established as one of the main tools for the early detection of kidney disease in clinical practice. The detection of a decreased eGFR (less than 60 mL/min/1.73 m2) is clinically relevant. This cut-off level establishes the diagnosis of kidney disease in adults. In 2022 SLANH and COLABIOCLI conducted a survey among the clinical laboratories from Latin America. The survey included 237 laboratories, 49% of which did not routinely report the eGFR. Based on this situation, SLANH and COLABIOCLI have elaborated the following consensus recommendations regarding the use of eGFR.

RESUMO

La miositis osificante traumática (MOT) es una enfermedad en la que ocurre osificación heterotópica en dos a cuatro semanas tras uno o múltiples traumatismos. El objetivo de este artículo es describir las características clínicas y radiológicas de un caso de MOT en un recién nacido (RN) después de la canulación intravenosa de vía periférica, poco frecuente en la práctica clínica en neonatología. Presentamos a un RN pretérmino de 33 semanas en que, a los 20 días de vida, se evidenció lesión tumoral en el tercio distal del antebrazo izquierdo de 3 cm por 2 cm, que no impresionaba dolor, ni limitación a la movilización, y en la que no había signos infecciosos. El resto del examen físico osteomuscular era normal. En la zona de lesión, tres semanas antes, se había instalado un catéter intravenoso periférico (CIVP). Una radiografía del antebrazo izquierdo demostró lesión calcificada al nivel de las partes blandas, sin disrupción de las estructuras óseas adyacentes; la ecografía del antebrazo reveló una imagen focal ovalada, de contornos parcialmente definidos, con sombra acústica posterior; el resto de los estudios de huesos largos era normal. Los niveles séricos de fosfatasa alcalina, calcio, fósforo también eran normales. En vista de la lesión tumoral al examen físico y la imagen calcificada en partes blandas a través de radiografía simple, con antecedente de microtraumas de VVP, se concluyó MOT. Se hizo seguimiento, con disminución del tamaño hasta que la lesión desapareció a los cuatro meses. No requirió control radiológico. La MOT es infrecuente en el RN, y, en general, la resolución es autolimitada y tiene buen pronóstico

Traumatic myositis ossificans (TMO) is a disorder in which heterotopic ossification occurs two to four weeks after one or multiple traumas. The goal of the present article is to describe the clinical and radiological characteristics of a case of TMO in a newborn (NB) after a peripheral intravenous cannulation, a rare procedure in the clinical practice of neonatology. The patient is a premature 33-week-old NB who, 20 days after birth, presented with a 3 cm x 2 cm lump in the distal third of the left forearm that did not seem to cause pain or to limit movements, and with no evidence of infection. The rest of the physical exam was within normal limits. Three weeks before the lesion, a peripheral intravenous catheter (PIVC) was placed in that area. A radiograph of the left forearm showed soft-tissue calcification without disruption of adjacent bone structures. Ultrasound revealed a focal, oval soft tissue lesion with partially-defined borders and posterior acoustic shadow; the rest of study showed normal long bones. The serum levels of alkaline phosphatase, calcium, and phosphorus were all normal. In view of the tumor lesion on the physical examination and the calcified image in softtissue on plain X-ray and a recent history of PIVC microtrauma, we reached to the diagnoses of TMO. During the follow-up, the lesion decreased in size until it completely disappeared four months after the diagnosis. No radiological control was needed. Uncommon in NBs, TMO is generally self-limited and with a good prognosis

RESUMO

OBJECTIVE: To assess effectiveness of pharmacologic interventions to relieve pain in patients suffering an acute stone episode. METHODS: Relevant trials that included patients with acute renal colic and radiological findings of urinary stones were identified in four databases. The main outcome was pain relief evaluated by Visual Analogue Scale score (VAS). RESULTS: In overall, diclofenac was superior to other NSAIDs for pain relief (MD of -12.57 [95% CI: -19.26, -5.88]). Paracetamol was superior to morphine for pain reduction at 30minutes (MD of -3.92 [95% CI: -6.41, -1.43]) and also to placebo at 15minutes (MD of -24.77 [95% CI: -33.19, -16.35]) and at 30minutes (MD of -16 [95% CI:-29, -2.96]) after drug administration. Finally, diclofenac was superior to paracetamol for pain reduction at 60 (MD of 6.60 [95% CI: 4.37, 8.83]) and 90minutes (MD of 3.4 [95% CI: 2.01, 4.79]). CONCLUSIONS: Diclofenac was superior to other NSAIDs and paracetamol for diminishing pain in patients suffering an acute stone episode. Paracetamol was superior to morphine and placebo for short pain relief. Future trials should address the role of paracetamol in the management of pain in patients suffering an acute stone episode.

RESUMO

Resumen ANTECEDENTES: la prehipertensión es una condición que aumenta el riesgo de padecer hipertensión arterial. Las concentraciones séricas elevadas de ácido úrico se asocian con hipertensión arterial y dificultan su control. OBJETIVO: evaluar las concentraciones circulantes de ácido úrico en pacientes prehipertensos en comparación con las de sujetos normotensos e hipertensos. MATERIAL Y MÉTODO: estudio clínico transversal en el que de enero a junio de 2016 las concentraciones séricas de ácido úrico se determinaron por método enzimático en pacientes con prehipertensión (de acuerdo con los criterios del JNC VII), así como en sujetos normotensos y sujetos hipertensos. Los métodos estadísticos usados fueron ANOVA y prueba exacta de Fisher. RESULTADOS: se incluyeron 90 pacientes con prehipertensión, 90 sujetos normotensos y 90 sujetos hipertensos. Encontramos que el grupo de prehipertensos tuvo valores significativamente mayores de ácido úrico que los normotensos (6.24±1.5 mg/dL vs 5.4±1.2 mg/dL, p=0.000206), mientras que aunque los valores en hipertensos fueron superiores (6.7±2 mg/dL), no alcanzaron significación estadística con los prehipertensos (p=0.99). Encontramos asociación significativa entre hiperuricemia con prehipertensión (p=0.015 IC 95%; 1.18-3.99). CONCLUSIONES: los pacientes prehipertensos mostraron concentraciones de ácido úrico superiores a las de los normotensos y aunque los valores mencionados fueron menores que en los hipertensos, esto no fue significativo. La hiperuricemia puede contribuir, al menos en parte, a mayor progresión hacia hipertensión arterial observada en los prehipertensos.

Abstract BACKGROUND: Prehypertension increases the risk of hypertension, serum uric acid levels are also associated with increased risk of hypertension. Increased levels of resistin and/or decreased levels of adiponectin are associated with cardiovascular mortality and the development of hypertension. OBJECTIVE: To evaluate uric acid serum levels in normotensive, prehypertensive and hypertensive patients. MATERIAL AND METHOD: A clinical, cross-sectional study was made from January to June 2016 in which circulating levels of uric acid were measured (enzymatic method) in normotensive, prehypertensive and hypertensive patients. Statistical analysis was performed with ANOVA and Fisher test. RESULTS: Ninety normotensive, 90 prehypertensive and 90 hypertensive patients were included. Prehypertensive patients have significantly greater levels of uric acid than normotensive subjects (6.24±1.5 mg/dL vs 5.4±1.2 mg/dL, p=0.000206). We also observed that hypertensive patients had increased, although non-significantly, values of uric acid than prehypertensive subjects (6.7±2 mg/dL, p=0.99). We also found a significantly association between hyperuricemia and prehypertension (p=0.015 IC 95%; 1.18-3.99). CONCLUSIONS: Prehypertensive patients had greater levels of uric acid when compared with normotensive subjects, this may explain why prehypertensive patients shown increased risk for hypertension than normotensive patients.

RESUMO

OBJECTIVE: To determine survival of a cohort of patients with acral lentiginous melanoma (ALM), treated at the National Cancer Institute of Colombia, the largest referral hospital of the country. METHODS: All patients diagnosed with an invasive ALM between 2003 and 2009 at the Colombian National Cancer Institute were included for analyses and followed for vital status and date of death. Using Kaplan-Meier methods, overall survival at 1, 3 and 5 years post diagnosis was determined, and Cox proportional hazards models were constructed for the variables showing a significant effect on survival in univariate analyses. RESULTS: Overall survival of this cohort of 90 patients was 77% at 1 year, 59% at 3 years and 54% at 5 years after diagnosis. Females had a better prognosis in univariate analyses but this advantage disappeared in multivariate models. Clinical stage was a strong predictor of survival, in univariate and multivariate models, particularly among elderly patients. CONCLUSIONS: Prognosis of ALM in Colombia is relatively poor, particularly for patients with higher clinical stage. The large proportions of ALM diagnosed in stage III and IV explain the relatively poor survival, and illustrate the importance of improving prognosis by lowering stage at diagnosis through better education and early detection programmes.

RESUMO

The objective was to analyze the association between disease occurrence during early lactation and reproductive performance and survival of dairy cows in high-producing herds, under different management practices in three geographic regions of Chile. Data included 30,757 lactation records of cows calving from January 2013 to June 2014 in three different locations: Central (C) area (n = 6198 cows in eight herds), Central-South (CS) area(n = 17,234 cows in 12 herds), and South (S) area (n = 7325 cows in six herds). Data were analyzed using logistic regression and ANOVA, considering cow as the experimental unit. Covariables offered to the models included parity number, season of calving, cow and herd relative milk yield, geographic location, and management system. Average milk yield (305 ME) per cow were 12,091, 11,783, and 6852 kg for C, CS, and S regions, respectively. Time from calving to first service and time to conception were consistently greater for cows with at least one disease event within 50 days in milk (DIM), for cows that were reported lame, or for cows that had mastitis or metritis. The odds (95% confidence interval) of pregnancy at 150 DIM (P150) and the odds of survival until 150 DIM (S150) for cows that had at least one disease event within 50 DIM were 0.84 (0.79-0.91) times the odds of pregnancy and 0.25 (0.22-0.28) times the odds of survival for healthy cows. The odds of P150 for cows located in the C and CS areas were 1.56 (1.36-1.80) and 1.16 (1.04-1.30) times the odds of P150 for cows in the S area. The odds of S150 for cows located in the C and CS areas were 0.48 (0.37-0.62) and 0.54 (0.42-0.67) times the odds of S150 for cows in the S area. These data suggested that cow health status and geographic location are significantly associated with reproductive performance and survival in this population of Chilean dairy cows.
