[Use of imaging criteria to identify cervical metastases using CT scans in head and neck tumours].

2008

Abstract Objective To assess the diagnostic certainty of CT images to identify regional spread of head and neck tumours. Patients and method A CT study was performed on 86 patients with neoplasms in the larynx and/or pharynx. After this, surgical dissection was performed for 142 neck sides. In the imaging study the following parameters were considered for all patients before suspecting malignant nodes: size of adenopathy bigger than 10–11 mm, irregular borders, central necrosis, spherical shape, capsular enhancement, and presence of groups with 3 or more lymphadenopathies. Results 48.5% of dissections were N+. Sensitivity and specificity for physical examination were 59% and 82%, respective…

Survival time and differences between dementia with Lewy bodies and Alzheimer’s disease following diagnosis: a meta-analysis of longitudinal studies.

2019

Objective: To synthesize the evidence across longitudinal studies comparing survival in dementia with Lewy bodies (DLB) and Alzheimer's disease (AD). Methods: We conducted a systematic review and meta-analysis of studies comparing survival in clinically diagnosed DLB to AD. Longitudinal cohort studies were identified through a systematic search of major electronic databases from inception to May 2018. A random effects meta-analysis was performed to calculate survival time and relative risk of death. Results: Overall, 11 studies were identified including 22,952 patients with dementia: 2029 with DLB (mean diagnosis age 76.3; 47% female) compared with 20,923 with AD (mean diagnosis age 77.2; 6…

1998

In this article, we show that the performances of 5- to 6-year-old children in arithmetic tests can be predicted from their performances in neuro-psychological tests administered a number of months in advance, independently of their level of development.

Sustained virological response to interferon-alpha is associated with improved outcome in HCV-related cirrhosis: a retrospective study

2007

The effect of achieving a sustained virological response (SVR) following interferon-α (IFNα) treatment on the clinical outcomes of patients with HCV-related cirrhosis is unknown. In an attempt to assess the risk of liver-related complications, HCC and liver-related mortality in patients with cirrhosis according to the response to IFNα treatment, a retrospective database was developed including all consecutive patients with HCV-related, histologically proven cirrhosis treated with IFNα monotherapy between January 1992 and December 1997. SVR was an undetectable serum HCV-RNA by PCR 24 weeks after IFNα discontinuation. HCC was assessed by ultrasound every 6 months. Independent predictors of al…

Definite and indeterminate nonalcoholic steatohepatitis share similar clinical features and prognosis : A longitudinal study of 1893 biopsy-proven no…

2021

[Background and Aim] Histological score systems may not fully capture the essential nonalcoholic steatohepatitis (NASH) features, which is one of the leading causes of screening failure in clinical trials. We assessed the NASH distribution and its components across the fibrosis stages and their impact on the prognosis and their relationship with the concept of metabolic-associated fatty liver disease (MAFLD).

Morphological and Postural Changes in the Foot during Pregnancy and Puerperium: A Longitudinal Study

2021

The aim of this study is to observe the morphological and postural changes to the foot that take place during pregnancy and the puerperium. Method: In this descriptive, observational, longitudinal study, we analysed 23 pregnant women, with particular attention to morphological and postural aspects of the foot, at three time points during and after pregnancy: in weeks 9–13 of gestation, weeks 32–35 of gestation and weeks 4–6 after delivery. The parameters considered were changes in foot length, the Foot Posture Index (FPI) and the Hernández Corvo Index, which were analysed using a pedigraph and taking into account the Body Mass Index (BMI). The same procedure was conducted in each review. Re…

Coping, stress, and personality in Spanish nursing students: A longitudinal study

2014

The purpose of this study was to examine the dominant stress coping style in nursing students, its relationships with stressful life events and personality traits, and the students' changes during their academic training. A non-experimental two-wave longitudinal design was carried out in 199 nursing students recruited from three Spanish nursing schools. The Stressful Life Events Scale, NEO-FFI, and COPE questionnaire were administered at the beginning (T1) and end (T2) of their nursing studies. Descriptive statistics, Anova(s), NPar tests, and Pearson correlations were carried out. Results show that nursing students' dominant coping style was emotion-focused coping, both at T1 and T2. Highl…

Catastrophic health expenditure: A comparative analysis of smoking and non-smoking households in China.

2020

Introduction Smoking is hazardous to health and places a heavy economic burden on individuals and their families. Clearly, smoking in China is prevalent since China is the largest consumer of tobacco in the world. Chinese smoking and nonsmoking households were compared in terms of the incidence and intensity of Catastrophic Health Expenditures (CHEs). The factors associated with catastrophic health expenditures were analyzed. Methods Data for this study were collected from two waves of panel data in 2011 and 2013 from the national China Health and Retirement Longitudinal Study (CHARLS). A total of 8073 households with at least one member aged above 45 were identified each year. Catastrophic…

Is processing speed a valid neurocognitive endophenotype in bipolar disorder? Evidence from a longitudinal, family study.

2021

[Background] Substantial evidence supports the existence of neurocognitive endophenotypes in bipolar disorder (BD), but very few longitudinal studies have included unaffected relatives. In a 5-year, follow-up, family study, we have recently suggested that deficits in manual motor speed and visual memory could be endophenotype candidates for BD. We aimed to explore whether this also applies to processing speed.
