Age related changes in the Q angle of non-professional football players.

Background: Football practice involves a great muscular demand, leading to the development of the lower limbs that, on occasions, can cause deviations from the normal anthropometric values. The quadriceps angle (Q angle) is a value often taken as a reference for the alignment of the lower limbs. Objective: To observe the changes of the Q angle in young football players, because of muscular effort, analyzing the differences between four groups of different ages and to determine whether the playing position might influence these variations. Methods: A cross sectional study was carried out with 104 male subjects divided into four groups according to age: under 8 years-old, 8-17 years-old, 17-21 years-old and over 21 years-old. A photograph was taken in standing position and the Q angle was plotted with KINOVEA® software. As for the reliability of the measurements, intraclass intra and interobserver coefficient were 0.958 and 0.860 respectively. The study was conducted in mid-season. Results: Q angle value is greater in those under 8 years of age and decreases gradually and significantly (p < 0.005) until 17-21 years of age, where it stabilizes at values of 5.73° ± 2.78 for right Q angle and 5.88° ± 2.55 for left Q angle. Two way ANOVA demonstrated a significant group*position interaction for goalkeepers with a medium effect size in both angles (p < 0.001) with a medium effect (η2 Right Q angle = 0.31; η2 Left Q angle = 0.37). The values remain unchanged in subjects over 21 years of age (p > 0.005), except for goalkeepers, who suffered a difference in the evolution of the angle within their age category (p < 0.005) and with a high effect size with the other positions (value > 0.8) except forward (value < 0.5). Conclusion: This study determines that the Q angle in football players decreases with growth, reaching values below 15° at the end of development. Playing positions only influence players over the age of 21, and the Q-angle of goalkeepers is greater than that of other players.

Acute liver failure due to anti-tuberculous treatment: when you travel without medical follow-up.

We present an uncommon cause of liver transplant in a patient with a particular personal situation, who suffered loss of follow-up during his antitubercular treatment. He presented a dress syndrome with fulminant liver failure that required a liver transplant. This case demonstrates the importance of close monitoring of liver function during this treatment.

Long-term clinical outcome and survival predictors in patients with cirrhosis after 10-mm-covered transjugular intrahepatic portosystemic shunt / Resultados clínicos a largo plazo y predictores de la supervivencia de pacientes con cirrosis hepática tras inserción de prótesis recubierta transyugular intrahepática porto-sistémica dilatadas a 10mm

Background and aims: Transjugular intrahepatic portosystemic shunts (TIPS) are successfully used in the management of portal hypertension (PH)-related complications. Debate surrounds the diameter of the dilation. The aim was to analyse the outcomes of and complications deriving from TIPS in patients with cirrhosis and identify predictors of survival. Methods: This was a retrospective single-centre study, which included patients with cirrhosis who had a TIPS procedure for PH from 2009 to October 2018. Demographic, clinical and radiological data were collected. The Kaplan–Meier method was used to measure survival and predictors of survival were identified with the Cox regression model. Results: A total of 98 patients were included (78.6% male), mean age was 58.5 (SD±/−9.9) and the median MELD was 13.3 (IQR 9.5–16). The indications were refractory ascites (RA), variceal bleeding (VB) and hepatic hydrothorax (HH). Median survival was 72 months (RA 46.4, VB 68.5 and HH 64.7) and transplant-free survival was 26 months. Clinical and technical success rates were 70.5% and 92.9% respectively. Age (HR 1.05), clinical success (HR 0.33), sodium (HR 0.92), renal failure (HR 2.46) and albumin (HR 0.35) were predictors of survival. Hepatic encephalopathy occurred in 28.6% of patients and TIPS dysfunction occurred in 16.3%. Conclusions: TIPS with 10-mm PTFE-covered stent is an effective and safe treatment for PH-related complications in patients with cirrhosis. Age, renal failure, sodium, albumin and clinical success are independent predictors of long-term survival.(AU)

Introducción: Los shunt intrahepático porto-sistémicos (TIPS) son utilizados con éxito en el tratamiento de las complicaciones de la hipertensión portal (HTP). Existe cierta controversia referente al diámetro dilatado. Los objetivos fueron analizar los resultados y las complicaciones derivadas de los TIPS en cirróticos, y determinar los factores predictores de la supervivencia. Métodos: Se trata de un estudio retrospectivo unicéntrico que incluyó pacientes cirróticos que recibieron un TIPS por HTP desde 2009 a octubre-2018. Se recogieron variables clínicas, demográficas y radiológicas. Se determinó la supervivencia mediante el método Kaplan-Meier y se identificaron los predictores de supervivencia con el modelo de regresión de Cox. Resultados: Se incluyeron 98 pacientes (78,6% varones). La media de edad fue de 58,5 años (DE ±9,9) y mediana de MELD 13,3 (RIC 9,5-16). Las indicaciones fueron ascitis refractaria (AR), hemorragia varicosa (HV) e hidrotórax hepático (HH). La mediana de supervivencia fue de 72 meses (AR 46,4; HV 68,5 y HH 64,7 meses) y la supervivencia libre de trasplante fue de 26 meses. El éxito técnico y clínico fue del 92,9 y 70,5%, respectivamente. La edad (HR 1,05), el éxito clínico (HR 0,33), el sodio (HR 0,92), la disfunción renal (HR 2,46) y la albúmina (HR 0,35) fueron factores predictivos de supervivencia. El 28,6% desarrolló encefalopatía hepática y un 16,3% presentó disfunción del TIPS. Conclusiones: Los TIPS con prótesis recubiertas dilatadas a 10mm son un tratamiento efectivo y seguro de las complicaciones derivadas de HTP en pacientes cirróticos. La edad, la disfunción renal, el sodio, la albúmina y el éxito clínico son factores independientes predictivos de la supervivencia a largo plazo.(AU)

De-novo nonalcoholic fatty liver disease at 5 years after liver transplantation: prevalence and predictive factors.

BACKGROUND AND AIMS: Nonalcoholic fatty liver disease (NAFLD) is a long-term complication after liver transplantation. Our aims were to determine de-novo-NAFLD at 5-year post-liver transplantation and identify predictive risk factors. METHODS: This was a retrospective analysis of de-novo-NAFLD at 5-year post-liver transplantation. NAFLD was defined as the radiological evidence of steatosis. Data from transplanted patients between November 2001 and May 2014 were collected. Noninvasive fibrosis scores were calculated. Predictors of de-novo NAFLD and survival were assessed by multivariate analyses and Kaplan-Meier method. RESULTS: A total of 252 liver transplantations were evaluated after applying exclusion criteria, (78.6% men) with 54.9 years old (SD ± 9.5). Prevalence of de-novo NAFLD at 5-year post-liver transplantation was 36.1%. Cardiovascular events were presented in 19.88% and 23.08% of non-NAFLD and NAFLD patients, (P = 0.58). On multivariate analysis, male sex (OR, 5.40; P = 0.001), obesity (OR, 3.72; P = 0.017), metabolic syndrome (OR, 4.69; P < 0.001) and de-novo diabetes (OR, 2.79; P = 0.018), were predictive. Significant fibrosis (≥F2) was presented in 58-86%. The mean survival in NAFLD and control group was 166.3 and 173.6 months, respectively (P = 0 0.50). CONCLUSION: De-novo NAFLD at fifth-year post-liver transplantation is frequently and associated with cardiovascular comorbidity. Male sex, obesity, de-novo diabetes and metabolic syndrome were factors associated with de-novo NAFLD. A significant proportion of patients had advanced fibrosis. This group trends toward worse patients' survival.

CONCLUSIONS: TIPS with 10-mm PTFE-covered stent is an effective and safe treatment for PH-related complications in patients with cirrhosis. Age, renal failure, sodium, albumin and clinical success are independent predictors of long-term survival.

Utility of Ethyl-Glucuronide for Evaluation of Abstinence in Patients Presenting for Liver Transplantation.

BACKGROUND: Cirrhosis as a result of alcohol-related liver disease is one of the most common indications for liver transplantation (LT) in Spain. Patients presenting for LT should be checked for alcohol abuse in clinical interviews and use of laboratory tests to confirm abstinence. The ethyl-glucuronide (EtG) test is very sensitive and can be positive in urine up to 5 days after consumption. Our main objective is to know the rate of alcohol abstinence by using the urine EtG test in patients evaluated for LT and to assess its correlation with the clinical interviews and laboratory test. METHODS: We conducted a prospective analysis of the results of the EtG in urine of patients evaluated for LT from January 2017 to March 2019 and its correlation with the medical and psychiatric interviews and with the laboratory test. RESULTS: We included 160 patients who were referred to LT evaluation. Among all cases, 84.1% were men, with an average age of 57.8 years. Alcohol-related liver disease was the most frequent cause (64.1%). Urine-EtG was positive in 10 patients (6.2%), 9 of them in patients with ALD and 1 in a patient with hepatitis C virus. The alcohol consumption was recognized by 80% of the patients in the clinical interview. Cases with positive EtG had higher levels of analytical parameters than those with a negative test. CONCLUSIONS: In our series, 6.2% of patients referred for LT evaluation had recently consumed alcohol. The determination of EtG in urine is probably an effective and objective technique in the detection of alcohol consumption to ensure abstinence in the LT candidates.

Immunosuppressive Treatment With mTOR Inhibitors for Malignancies After Liver Transplantation: Long-Term Survival Retrospective Analysis.

BACKGROUND: Immunosuppressive calcineurin inhibitors have been associated with an increased risk of post-transplant malignancies. The mammalian target of rapamycin inhibitors (mTORi) is an alternative immunosuppressive regimen with an antineoplastic effect. The aim of the study was to determine the long-term survival of mTORi-treated recipients with de novo or recurring tumors after liver transplantation (LT). METHODS: This retrospective analysis included mTORi-treated LT recipients between March 2013 and March 2019. We analyzed long-term survival and mTORi indications in an oncology setting in patients with de novo and recurrent malignancies after LT. Overall survival (OS) rate was compared from the Spanish Liver Transplant Registry (SLTR) data using the Kaplan-Meier method. High-risk hepatocellular carcinoma (HCC) was defined as microvascular invasion or satellite lesions as described in the liver explant. RESULTS: A total of 237 patients underwent LT during the study period; 111 patients underwent mTORi-based immunosuppression (48%, cancer was the main indication): 24.5% high-risk HCC; 24.4% HCC recurrence; 14.3% cholangiocarcinoma; and 36.7% de novo malignancies. The 1- and 5-year OS rates after LT in the mTORi group were 83% and 65%, respectively (SLTR group, 85% and 72.6%, respectively); 30.6% patients received mTORi monotherapy, and 38.7% patients had an early switch to mTORi in the first 3 months after oncologic diagnosis. mTORi monotherapy or oncologic treatment strategies had a nonsignificant association with prognosis. The OS rate was higher when the mTORi switch occurred early, 83% and 67%, respectively. CONCLUSIONS: mTORi-based immunosuppression may be a preferred option in patients transplanted with tumors. The OS rate was comparable to data from the SLTR. An mTORi early switch improves OS rate.
