RESUMO

Body composition and phase angle (PhA) have been used to predict mortality in multiple diseases. However, little has been studied regarding segmental measurements, which could potentially help assess subtle changes in specific tissue segments. This study aimed to identify the total PhA cut-off point associated with mortality risk and changes in body composition within a week of hospitalisation in non-critical hospitalised patients with COVID-19. A cohort study was conducted where patients underwent to a complete nutritional assessment upon admission and after seven days, and followed up until hospital discharge or death. A receiver operating characteristic curve was constructed to determine the PhA cut-off point, and the Kaplan­Meier estimator was used to determine survival analysis. Segmental and complete body compositions on admission and after 7 d were compared. We included 110 patients (60 men) with a mean age of 50·5 ± 15·0 years and a median BMI of 28·5 (IQR, 25·6­33·5) kg/m2. The median length of hospital stay was 6 (IQR, 4­9) d, and the mortality rate was 13·6 %. The PhA cut-off point obtained was 4°, with significant differences in the survival rate (P < 0·001) and mortality (HR = 5·81, 95 % CI: 1·80, 18·67, P = 0·003). Segmental and whole-body compositions were negatively affected within one week of hospitalisation, with changes in the approach by the graphical method in both sexes. Nutritional status deteriorates within a week of hospitalisation. PhA < 4° is strongly associated with increased mortality in non-critical hospitalised patients with COVID-19.

RESUMO

BACKGROUND: Hepatorenal syndrome is a condition that occurs in people with chronic liver disease (such as alcoholic hepatitis, advanced cirrhosis, or fulminant liver failure) and portal hypertension. The prognosis is dismal, often with a survival of weeks to months. Hepatorenal syndrome is characterised by the development of intense splanchnic vasodilation favouring ascites and hypotension leading to renal vasoconstriction and acute renal failure. Therefore, treatment attempts focus on improving arterial pressure through the use of vasopressors, paracentesis, and increasing renal perfusion pressure. Several authors have reported that the placement of transjugular intrahepatic portosystemic shunts (TIPS) may be a therapeutic option because it decreases portal pressure and improves arterial and renal pressures. However, the evidence is not clearly documented and TIPS may cause adverse events. Accordingly, it is necessary to evaluate the evidence of the benefits and harms of TIPS to assess its value in people with hepatorenal syndrome. OBJECTIVES: To evaluate the benefits and harms of transjugular intrahepatic portosystemic shunts (TIPS) in adults with hepatorenal syndrome compared with sham, no intervention, conventional treatment, or other treatments. SEARCH METHODS: We used standard, extensive Cochrane search methods. The latest search date was 2 June 2023. SELECTION CRITERIA: We included only randomised clinical trials with a parallel-group design, which compared the TIPS placement with sham, no intervention, conventional therapy, or other therapies, in adults aged 18 years or older, regardless of sex or ethnicity, diagnosed with chronic liver disease and hepatorenal syndrome. We excluded trials of adults with kidney failure due to causes not related to hepatorenal syndrome, and we also excluded data from quasi-randomised, cross-over, and observational study designs as we did not design a separate search for such studies. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes were 1. all-cause mortality, 2. morbidity due to any cause, and 3. serious adverse events. Our secondary outcomes were 1. health-related quality of life, 2. non-serious adverse events, 3. participants who did not receive a liver transplant, 4. participants without improvement in kidney function, and 5. length of hospitalisation. We performed fixed-effect and random-effects meta-analyses using risk ratio (RR) or Peto odds ratio (Peto OR), with 95% confidence intervals (CI) for the dichotomous outcomes and mean difference (MD) or standardised mean difference (SMD) for the continuous outcomes. We used GRADE to assess certainty of evidence. MAIN RESULTS: We included two randomised clinical trials comparing TIPS placement (64 participants) versus conventional treatment (paracentesis plus albumin 8 g/L of removed ascites) (66 participants). The co-interventions used in the trials were dietary treatment (sodium less than 60 mmoL/day), spironolactone (300 mg/day to 400 mg/day), and furosemide (120 mg/day). Follow-up was up to 24 months. Both were multicentre trials from Spain and the USA, and Germany, conducted between 1993 and 2002. Most participants were men (aged 18 to 75 years). We are uncertain about the effect of TIPS placement compared with conventional treatment, during the first 24 months of follow-up, on all-cause mortality (RR 0.88, 95% CI 0.55 to 1.38; 2 trials, 130 participants; I2 = 58%; very low-certainty evidence) and on the development of any serious adverse event (RR 1.60, 95% CI 0.10 to 24.59; 2 trials, 130 participants; I2 = 78%; very low-certainty evidence). The use of TIPS may or may not result in a decrease in overall morbidity such as bacterial peritonitis, encephalopathy, or refractory ascites, during the first 24 months of follow-up, compared with the conventional treatment (RR 0.95, 95% CI 0.77 to 1.18; 2 trials, 130 participants; I2 = 0%; low-certainty evidence). We are uncertain about the effect of TIPS placement versus conventional treatment on the number of people who did not receive a liver transplant (RR 1.03, 95% CI 0.93 to 1.14; 2 trials, 130 participants; I2 = 0%; very low-certainty evidence) or on the length of hospitalisation (MD -20.0 days, 95% CI -39.92 to -0.08; 1 trial, 60 participants; very low-certainty evidence). Kidney function may improve in participants with TIPS placement (RR 0.53, 95% CI 0.27 to 1.02; 1 trial, 70 participants; low-certainty evidence). No trials reported health-related quality of life, non-serious adverse events, or number of participants with improvement in liver function associated with the TIPS placement. Funding No trials reported sources of commercial funding or conflicts of interest between researchers. Ongoing studies We found one ongoing trial comparing TIPS with conventional therapy (terlipressin plus albumin) and listed one study as awaiting classification as no full-text article could be found. AUTHORS' CONCLUSIONS: TIPS placement was compared with conventional treatment, with a follow-up of 24 months, in adults with hepatorenal syndrome type 2. Based on two trials with insufficient sample size and trial limitations, we assessed the overall certainty of evidence as low or very low. We are unsure if TIPS may decrease all-cause mortality, serious adverse events, the number of people who did not receive a liver transplant, and the days of hospitalisation because of the very low-certainty evidence. We are unsure if TIPS, compared with conventional treatment, has better effects on overall morbidity (bacterial peritonitis, encephalopathy, or refractory ascites). TIPS may improve kidney function, but the certainty of evidence is low. The trials included no data on health-related quality of life, non-serious adverse events, and liver function associated with the TIPS placement. We identified one ongoing trial and one study awaiting classification which may contribute to the review when information becomes available.

RESUMO

Introduction: Management of pediatric cancer patients involves invasive procedures such as punctures, injections, catheter placements, and chemotherapy which can generate fatigue, nausea, vomiting, anxiety, and pain. Virtual Reality (VR) is a nonpharmacological intervention classified as a cognitive-behavioral method to relieve symptoms. Methods: We designed a crossover protocol and included 20 patients between 9 and 12 years old; ten were male. All patients had acute lymphoblastic leukemia diagnosis and were treatedwith St. Jude's XV protocol in the maintenance phase. Pain and anxiety were measured with validated scales in the pediatric population. Results: Although we used a small group of patients, we found statistical difference in the reduction of anxiety and perception of time. Discussion: These results open a window to non-pharmacological treatments and show a strategy to improve quality of life in children inside the hospital.

RESUMO

Abstract Background: The association between childhood cancer and socioeconomic status has been widely studied. However, none of the results are conclusive. This study aimed to analyze the association between the Human Development Index (HDI) and the acute lymphoblastic leukemia (ALL) incidence in children under the Popular Medical Insurance Care. Methods: We conducted an observational, descriptive, and population-based study covering 55% of the Mexican population (58 million). Results: The most impoverished states were located in the south east region of Mexico, while the north was more homogeneous, with HDIs varying between 0.73 and 0.79. Our findings emphasize that the metropolitan area of Mexico City and the State of Nuevo Leon have the highest levels of HDI. Regions were graded from I to IV according to their HDIs in ascending order. The HDIs varied from 0.667 to 0.830/100,000 children/year, with a national average of 0.746. The leukemia incidence for regions I, II, III, and IV was 6.12, 6.53, 4.96, and 9.95. An analysis of ALL incidence in Mexico showed significant differences for region IV in comparison with the other regions based on the HDI values (p = 0.0001). Conclusions: Further in-depth studies, including the economic aspects of the different geographic regions and their ethnographic characteristics, would give a more comprehensive panorama.


Resumen Introducción: Se ha estudiado la relación entre el nivel socioeconómico y el cáncer en niños. Sin embargo, aún no existen resultados concluyentes. El objetivo de este trabajo fue analizar la asociación entre el Índice de Desarrollo Humano (IDH) y la incidencia de leucemia linfoblástica aguda en niños atendidos por el Seguro Popular. Métodos: Se realizó un estudio observacional y descriptivo. La población estudiada representa el 55% de la población mexicana (58 millones). Resultados: Los Estados más pobres se localizaron en la región sureste de México, mientras que el norte del país fue más homogéneo, con un IDH que varió entre 0.73 y 0.79. Los hallazgos muestran que el área metropolitana de la Ciudad de México y el Estado de Nuevo León tienen un IDH más alto. Las regiones se graduaron del I al IV en orden ascendente de acuerdo con su IDH. El IDH varió de 0.667 a 0.830 por 100,000 niños por año, con un promedio nacional de 0.746. La incidencia de leucemia por 100,000 niños por año en las regiones I, II, III y IV fue de 6.12, 6.53, 4.96 y 9.95, respectivamente. El análisis de variabilidad de la incidencia de leucemia linfoblástica aguda en México muestra diferencias entre la región IV y el resto de las regiones de acuerdo con los valores del IDH (p = 0.0001). Conclusiones: Se deben realizar estudios más profundos que consideren no solo los aspectos económicos de las diferentes regiones, sino también sus características etnográficas, lo cual podría dar un panorama más amplio.
