RESUMEN

Objective: To analyze the validity of self and informant reports, depressive symptomatology, and some sociodemographic variables to predict the risk of cognitive decline at different follow-up times. Methods: A total of 337 participants over 50 years of age included in the CompAS and classified as Cognitively Unimpaired (CU), Subjective Cognitive Decline (SCD) and Mild Cognitive Impairment (MCI) groups were assessed at baseline and three follow-ups. A short version of the QAM was administered to assess the severity of subjective cognitive complaints (SCCs), and the GDS-15 was used to evaluate the depressive symptoms. At each follow-up assessment, participants were reclassified according to the stability, regression or progression of their conditions. Logistic regression analysis was used to predict which CU, SCD and MCI participants would remain stable, regress or progress at a 3rd follow-up by using self- and informant-reported complaints, depressive symptomatology, age and education at baseline and 2nd follow-ups as the predictive variables. Results: Overall, self-reported complaints predicted progression between the asymptomatic and presymptomatic stages. As the objective deterioration increased, i.e., when SCD progressed to MCI or dementia, the SCCs reported by informants proved the best predictors of progression. Depressive symptomatology was also a predictor of progression from CU to SCD and from SCD to MCI. Conclusion: A late increase in self-reported complaints make valid estimates to predict subjective decline at asymptomatic stages. However, an early increase in complaints reported by informants was more accurate in predicting objective decline from asymptomatic stages. Both, early and late decrease in self-reported complaints successfully predict dementia from prodromic stage. Only late decrease in self-reported complaints predict reversion from prodromic and pre-symptomatic stages.

RESUMEN

Episodic memory (EM), one of the most commonly assessed cognitive domains in aging, is useful for identifying pathological processes such as mild cognitive impairment and dementia. However, EM tests must be culturally adapted, and the influence of sociodemographic variables analyzed, to provide cut-off points that enable correct diagnosis. The aim of this article is to report updated Spanish normative data for three EM tests: the California Verbal Learning Test, the Logical Memory subtest of the Wechsler Memory Test, and the Rivermead Behavioral Memory Test. Measures include immediate, short-, and long-delay free recall, intrusions, and global scores. The entire sample is comprised of 1,193 cognitively unimpaired participants aged +50, recruited from three cohort studies within the Spanish Consortium for Ageing Normative Data. Participants who subsequently developed cognitive impairment, detected at follow-up, were removed from the total sample. Data analysis included transformation of percentile ranges into scalar scores, tests for the effects of education level, age, and sex on performance, and linear regression to calculate scalar adjustments. Tables with percentile ranges and scalar scores for each measure are provided, with adjustments for age, education level, and sex, as required. The normative scores provide robust data for assessing EM in Spanish middle-aged and old populations. Effects of sex, age, and education level in each measure are discussed.

RESUMEN

IMPORTANCE: Testicular adrenal rest tumors (TARTs), often found in male patients with congenital adrenal hyperplasia (CAH), are benign lesions causing testicular damage and infertility. We hypothesize that chronically elevated adrenocorticotropic hormone exposure during early life may promote TART development. OBJECTIVE: This study aimed to examine the association between commencing adequate glucocorticoid treatment early after birth and TART development. DESIGN AND PARTICIPANTS: This retrospective multicenter (n = 22) open cohort study collected longitudinal clinical and biochemical data of the first 4 years of life using the I-CAH registry and included 188 male patients (median age 13 years; interquartile range: 10-17) with 21-hydroxylase deficiency (n = 181) or 11-hydroxylase deficiency (n = 7). All patients underwent at least 1 testicular ultrasound. RESULTS: TART was detected in 72 (38%) of the patients. Prevalence varied between centers. When adjusted for CAH phenotype, a delayed CAH diagnosis of >1 year, compared with a diagnosis within 1 month of life, was associated with a 2.6 times higher risk of TART diagnosis. TART onset was not predicted by biochemical disease control or bone age advancement in the first 4 years of life, but increased height standard deviation scores at the end of the 4-year study period were associated with a 27% higher risk of TART diagnosis. CONCLUSIONS AND RELEVANCE: A delayed CAH diagnosis of >1 year vs CAH diagnosis within 1 month after birth was associated with a higher risk of TART development, which may be attributed to poor disease control in early life.

RESUMEN

INTRODUCTION: The COVID-19 pandemic has led to major changes in the day-to-day operations of residential care facilities. Little is known about the impact it has had on professionals working in nursing homes in Spain. This research arose from the need to explore the situation experienced during the pandemic and to delve into the experiences as narrated by professionals working in nursing homes. The aim of the RESICOVID study was to analyze the effects on professionals of the measures taken in response to the COVID-19 pandemic in nursing homes. MATERIAL AND METHOD: 31 professionals (mean age: 32.9 years; 83.8% women, in various areas of care) were interviewed. Seventy-one percent of the sample presented a diagnosis of COVID-19. The analysis was performed with the Atlas-ti v8 program. RESULTS: From the analysis of the interviews, 128 quotations were extracted, coded in the following dimensions: 1. experience of confinement; 2. perception of changes; 3. health problems; 4. cognitive and functional changes; 5. loneliness. CONCLUSIONS: Burnout, overload, lack of resources and uncertainty caused by the COVID-19 pandemic have generated feelings of fear, exhaustion, anxiety, frustration and sadness in professionals who continue to this day without sufficient resources to face the situation. The design of contingency plans for future health crises should take into account this impact on care professionals.

RESUMEN

OBJECTIVE: Congenital adrenal hyperplasia (CAH) requires exogenous steroid replacement. Treatment is commonly monitored by measuring 17-OH progesterone (17OHP) and androstenedione (D4). DESIGN: Retrospective cohort study using real-world data to evaluate 17OHP and D4 in relation to hydrocortisone (HC) dose in CAH patients treated in 14 countries. PATIENTS: Pseudonymized data from children with 21-hydroxylase deficiency (21OHD) recorded in the International CAH Registry. MEASUREMENTS: Assessments between January 2000 and October 2020 in patients prescribed HC were reviewed to summarise biomarkers 17OHP and D4 and HC dose. Longitudinal assessment of measures was carried out using linear mixed-effects models (LMEM). RESULTS: Cohort of 345 patients, 52.2% female, median age 4.3 years (interquartile range: 3.1-9.2) were taking a median 11.3 mg/m2 /day (8.6-14.4) of HC. Median 17OHP was 35.7 nmol/l (3.0-104.0). Median D4 under 12 years was 0 nmol/L (0-2.0) and above 12 years was 10.5 nmol/L (3.9-21.0). There were significant differences in biomarker values between centres (p < 0.05). Correlation between D4 and 17OHP was good in multiple regression with age (p < 0.001, R2 = 0.29). In longitudinal assessment, 17OHP levels did not change with age, whereas D4 levels increased with age (p < 0.001, R2 = 0.08). Neither biomarker varied directly with dose or weight (p > 0.05). Multivariate LMEM showed HC dose decreasing by 1.0 mg/m2 /day for every 1 point increase in weight standard deviation score. DISCUSSION: Registry data show large variability in 17OHP and D4 between centres. 17OHP correlates with D4 well when accounting for age. Prescribed HC dose per body surface area decreased with weight gain.

RESUMEN

Introducción: La pandemia por la COVID-19 ha generado grandes cambios en el funcionamiento diario de los centros residenciales; poco se sabe del impacto que ha tenido en los profesionales que trabajan en residencias de personas mayores en España. Esta investigación surge por la necesidad de explorar cuál ha sido la situación vivida durante la pandemia y profundizar en las experiencias tal y como son narradas por los profesionales que trabajan en las residencias para personas mayores. El objetivo del estudio RESICOVID ha sido analizar los efectos en los profesionales de las medidas que se tomaron en las residencias frente a la pandemia por COVID-19.Material y métodos: Se realizaron entrevistas a 31 profesionales del cuidado (media edad: 34,31 años, DS: 9,56; 83,8% mujeres). El 71% de los participantes tuvieron diagnóstico de COVID-19. El análisis fue realizado con el programa Atlas-ti v8.Resultados: Del análisis de las entrevistas se extrajeron 128 citas que fueron codificadas en las siguientes dimensiones: 1. vivencia del confinamiento; 2. percepción de cambios; 3. problemas de salud; 4. cambios en el área cognitiva y funcional; 5. soledad.Conclusiones: La sobrecarga, la falta de recursos y la incertidumbre causada por la pandemia por COVID-19 ha generado sentimientos de miedo, desgaste, ansiedad, frustración y tristeza en los profesionales que continúan a día de hoy sin recursos suficientes para encarar la situación. El diseño de planes de contingencia para futuras crisis sanitarias deberá tener en cuenta este impacto en los profesionales del cuidado. (AU)

RESUMEN

The von Hippel-Lindau (VHL) disease is an autosomal dominant cancer syndrome caused by mutations in the VHL tumor suppressor gene. VHL protein (pVHL) forms a complex (VBC) with Elongins B-C, Cullin2, and Rbx1. Although other functions have been discovered, the most described function of pVHL is to recognize and target hypoxia-inducible factor (HIF) for degradation. This work comprises the functional characterization of two novel variants of the VHL gene (P138R and L163R) that have been described in our center in patients with VHL disease by in vitro, in vivo, and in silico approaches. In vitro, we found that these variants have a significantly shorter half-life compared to wild-type VHL but still form a functional VBC complex. Altered fibronectin deposition was evidenced for both variants using immunofluorescence. In vivo studies revealed that both variants failed to suppress tumor growth. By means of molecular dynamics simulations, we inspected in silico the nature of the changes introduced by each variant in the VBC complex. We have demonstrated the pathogenicity of P138R and L163R novel variants, involving HIF-dependent and HIF-independent mechanisms. These results provide the basis for future studies regarding the impact of structural alterations on posttranslational modifications that drive pVHL's fate and functions.

RESUMEN

Objectives: International guidelines recommend additional salt supplementation during infancy in classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. The influence of corticoid medication and growth has not been assessed. Aim: To investigate the current use of salt supplementation, fludrocortisone (FC) and hydrocortisone (HC) dosage as well as weight, height, BMI and blood pressure (BP) in CAH children aged 0-3 years. Methods: Retrospective multicentre analysis using data from the I-CAH registry. Salt-treated (ST) and non-salt-treated (NST) children were compared regarding FC and HC dosage, weight, height and BP at 0, 3, 6, 9, 12, 18, 24, 30, and 36 months. Results: We analysed 2483 visits of 331 patients born after year 2000 in 13 countries (male, n = 145) with 203 ST patients (61%). NST children had significantly higher FC dosages at 1.5-4.5 months and higher HC dosages until 1.5 months of age. No differences in weight, length and BP between subgroups were observed. Children of the whole cohort showed increased BMI-SDS during the study period and about half of the reported BP readings were >P95. Conclusion: In children treated with additional salt supplementation, FC and HC dosages are lower during the first months of life but without differences in weight, length and BP until 3 years of age compared to NST children. All children showed an increase in BMI-SDS and a high rate of BP readings >P95 until 3 years, indicating the start of weight gain and negative effects on blood pressure already in very early life.

RESUMEN

Introduction: This study aimed to evaluate, in adults with mild cognitive impairment (MCI), the brain atrophy that may distinguish between three AT(N) biomarker-based profiles, and to determine its clinical value. Methods: Structural MRI (sMRI) was employed to evaluate the volume and cortical thickness differences in MCI patients with different AT(N) profiles, namely, A-T-(N)-: normal AD biomarkers; A+T-(N)-: AD pathologic change; and A+T+(N)+: prodromal AD. Sensitivity and specificity of these changes were also estimated. Results: An initial atrophy in medial temporal lobe (MTL) areas was found in the A+T-(N)- and A+T+(N)+ groups, spreading toward the parietal and frontal regions in A+T+(N)+ patients. These structural changes allowed distinguishing AT(N) profiles within the AD continuum; however, the profiles and their pattern of neurodegeneration were unsuccessful to determine the current clinical status. Conclusion: sMRI is useful in the determination of the specific brain structural changes of AT(N) profiles along the AD continuum, allowing differentiation between MCI adults with or without pathological AD biomarkers.

RESUMEN

(1) Background: Long-term care facilities (LTCFs) have been harmed by the coronavirus, and older adults have remained isolated for a long time with many restrictions. The aim of this study was to measure the decline in cognitive, functional, and affective status in a care facility after the lockdown in the first wave of the COVID-19 pandemic and to compare it with previous measures in order to determine if this decline was accelerated. (2) Methods: Ninety-eight participants were recruited. Data from three retrospective pre-lockdown assessments and an additional post-lockdown assessment were analyzed. Mixed ANOVA analyses were performed according to the Clinical Dementia Rating levels, considering social-contact frequency during the lockdown as a covariate. (3) Results: The cognitive and functional scores were lower and depression scores were higher after the strict lockdown, accelerating a general pattern of decline that was already present in LTCF residents. The frequency of social contact eliminated the measurement differences in the cognitive and functional scores and the group differences in depression scores. (4) Conclusions: The effects of the SARS-CoV-2 lockdown in an LTCF were mediated by the frequency of contact. Clinical implications: Preventive measures must be taken to ensure social contact with relatives and friends and reduce the negative consequences of social isolation in LTCFs.

RESUMEN

In this article international trends in surgical practice in girls with congenital adrenal hyperplasia (CAH) are evaluated. All cases that had been classified in the I-CAH/I-DSD registry as 46,XX CAH and who were born prior to 2017 were identified. Centers were approached to obtain information on surgical decision making. Of the 330 included participants, 208 (63.0%) presented within the first month of life, and 326 (98.8%) cases were assigned female. Genital surgery had been performed in 250 (75.8%). A total of 64.3, 89.2, and 96.8% of cases residing in Europe, South America and Asia, respectively, had at least one surgery. In a logistic regression model for the probability of surgery before the second birthday (early surgery) over time an increase of probability for early vaginal surgery could be identified, but not for clitoral surgery or both surgeries combined. Genitoplasty in girls with CAH remains controversial. This large international study provides a snapshot of current practice and reveals geographical and temporal differences. Fewer surgeries were reported for Europe, and there seems to be a significant trend towards aiming for vaginal surgery within the first 2 years of life.

RESUMEN

OBJETIVE: We followed our previously reported algorithm based on intra and postoperative parathyroid hormone (PTH) levels to predict postthyroidectomy hypoparathyroid hypocalcemia. The objective of the study was to assess if this strategy is useful and safe to reduce hypocalcemia, hospitalisation length and postsurgery calcium sampling. DESIGN, PATIENTS, MEASSUREMENTS: We classified our series of 66 patients according to their risk of hypoparathyroidism based on PTH determinations. We treated high-risk patients with calcium and vitamin D1-25 supplementation and obtained routine daily calcium samples to control low-risk patients until 48 h postsurgery. We compared the outcomes and overall results of this new approach with those of a historical control group of patients with equivalent PTH measurements who were treated only if they presented hypocalcemia. RESULTS: In the high-risk subgroup (n = 30), five patients had hypocalcemia within the first 24 h. Compared with the high-risk control subgroup, the incidence of hypocalcemia fell from 100% to 17% (p < .001), and the median hospitalisation length from 6 to 3 days (p < .001). In the low-risk subgroup (n = 36), 28 patients remained normocalcemic with significantly less calcium sampling (p < .001). Eight patients had hypocalcemia; seven of them required neck dissection, which was the only risk factor related to postsurgical hypoparathyroidism (RR: 2.1 [confidence interval 95%: 1.4-3.1]; p < .001). The overall incidence of hypocalcemia decreased by 58% in our patients compared to the control group. CONCLUSIONS: Assessing PTH levels to classify the risk of hypoparathyroidism and to initiate preventive therapy was an effective approach that improved the safety of our paediatric patients by reducing the incidence of hypocalcemia and the length of hospitalisation after thyroidectomy in paediatric patients.

RESUMEN

El raquitismo afecta la diferenciación y mineralización del cartílago de crecimiento como consecuencia, en última instancia, de una alteración en los niveles de fósforo y/o calcio. El secundario a la deficiencia de vitamina D es la forma más frecuente (raquitismo carencial). Las manifestaciones clínicas durante los primeros años de vida suelen comprometer en forma más marcada las epífisis de los huesos.Se describe el caso de un lactante de 8 meses con diagnóstico de alergia a la proteína de la leche de vaca que presentó múltiples fracturas patológicas mientras se encontraba bajo tratamiento con fórmulas lácteas a base de aminoácidos. Se efectuó el diagnóstico de raquitismo hipofosfatémico por deficiencia de fósforo y, tras 3 meses de tratamiento con sales de fosfato, calcio, calcitriol, el abandono paulatino de la leche elemental y el descenso gradual de la medicación antiácida, el paciente evolucionó con curación clínico-radiológica del cuadro


The rickets is a disease that affects the differentiation and mineralization of the growth cartilage, as an ultimate consequence of a balance loss in calcium and phosphate levels. Vitamin D deficiency is the most common cause of the rickets (nutritional rickets). Its clinical manifestation during the first years of life involves long bones epiphysis in a more severe way.We report an 8-month-old infant who was diagnosed with cow ́s milk protein allergy and suffered from multiple fractures while receiving elemental formula as part of his treatment. The final etiology was hypophosphatemic rickets secondary to phosphate deficiency, and after 3 months of phosphate, calcium and calcitriol supplementation, in addition to the gradually reduction of the proportion of elemental formula intake and the decline of the antacid doses, clinical and radiological heal was achieved.

RESUMEN

OBJECTIVE: Despite published guidelines no unified approach to hormone replacement in congenital adrenal hyperplasia (CAH) exists. We aimed to explore geographical and temporal variations in the treatment with glucocorticoids and mineralocorticoids in CAH. DESIGN: This retrospective multi-center study, including 31 centers (16 countries), analyzed data from the International-CAH Registry. METHODS: Data were collected from 461 patients aged 0-18 years with classic 21-hydroxylase deficiency (54.9% females) under follow-up between 1982 and 2018. Type, dose and timing of glucocorticoid and mineralocorticoid replacement were analyzed from 4174 patient visits. RESULTS: The most frequently used glucocorticoid was hydrocortisone (87.6%). Overall, there were significant differences between age groups with regards to daily hydrocortisone-equivalent dose for body surface, with the lowest dose (median with interquartile range) of 12.0 (10.0-14.5) mg/m2/day at age 1-8 years and the highest dose of 14.0 (11.6-17.4) mg/m2/day at age 12-18 years. Glucocorticoid doses decreased after 2010 in patients 0-8 years (P < 0.001) and remained unchanged in patients aged 8-18 years. Fludrocortisone was used in 92% of patients, with relative doses decreasing with age. A wide variation was observed among countries with regards to all aspects of steroid hormone replacement. CONCLUSIONS: Data from the I-CAH Registry suggests international variations in hormone replacement therapy, with a tendency to treatment with high doses in children.

RESUMEN

Disorders of Sex Development (DSD) are anomalies occurring in the process of fetal sexual differentiation that result in a discordance between the chromosomal sex and the sex of the gonads and/or the internal and/or external genitalia. Congenital disorders affecting adrenal function may be associated with DSD in both 46,XX and 46,XY individuals, but the pathogenic mechanisms differ. While in 46,XX cases, the adrenal steroidogenic disorder is responsible for the genital anomalies, in 46,XY patients DSD results from the associated testicular dysfunction. Primary adrenal insufficiency, characterized by a reduction in cortisol secretion and overproduction of ACTH, is the rule. In addition, patients may exhibit aldosterone deficiency leading to salt-wasting crises that may be life-threatening. The trophic effect of ACTH provokes congenital adrenal hyperplasia (CAH). Adrenal steroidogenic defects leading to 46,XX DSD are 21-hydroxylase deficiency, by far the most prevalent, and 11ß-hydroxylase deficiency. Lipoid Congenital Adrenal Hyperplasia due to StAR defects, and cytochrome P450scc and P450c17 deficiencies cause DSD in 46,XY newborns. Mutations in SF1 may also result in combined adrenal and testicular failure leading to DSD in 46,XY individuals. Finally, impaired activities of 3ßHSD2 or POR may lead to DSD in both 46,XX and 46,XY individuals.

RESUMEN

BACKGROUND: Although congenital adrenal hyperplasia (CAH) is known to be associated with adrenal crises (AC), its association with patient- or clinician-reported sick day episodes (SDE) is less clear. METHODS: Data on children with classic 21-hydroxylase deficiency CAH from 34 centers in 18 countries, of which 7 were Low or Middle Income Countries (LMIC) and 11 were High Income (HIC), were collected from the International CAH Registry and analyzed to examine the clinical factors associated with SDE and AC. RESULTS: A total of 518 children-with a median of 11 children (range 1, 53) per center-had 5388 visits evaluated over a total of 2300 patient-years. The median number of AC and SDE per patient-year per center was 0 (0, 3) and 0.4 (0.0, 13.3), respectively. Of the 1544 SDE, an AC was reported in 62 (4%), with no fatalities. Infectious illness was the most frequent precipitating event, reported in 1105 (72%) and 29 (47%) of SDE and AC, respectively. On comparing cases from LMIC and HIC, the median SDE per patient-year was 0.75 (0, 13.3) vs 0.11 (0, 12.0) (P < 0.001), respectively, and the median AC per patient-year was 0 (0, 2.2) vs 0 (0, 3.0) (P = 0.43), respectively. CONCLUSIONS: The real-world data that are collected within the I-CAH Registry show wide variability in the reported occurrence of adrenal insufficiency-related adverse events. As these data become increasingly used as a clinical benchmark in CAH care, there is a need for further research to improve and standardize the definition of SDE.

RESUMEN

El incremento de la expectativa de vida con el advenimiento de la terapia antirretroviral de alta eficacia plantea desafíos en cuanto a la toxicidad e interacciones medicamentosas. El síndrome de Cushing exógeno por interacción entre ritonavir y fluticasona inhalada en niños con diagnóstico de infección por virus de la inmunodeficiencia humana y patología pulmonar crónica es infrecuente. Hasta el momento, hay 20 casos reportados. Se describen 3 casos pediátricos con diagnóstico de infección por virus de la inmunodeficiencia humana y patología pulmonar crónica que presentaron síndrome de Cushing exógeno con fluticasona inhalada en dosis habituales por la interacción medicamentosa entre esta y ritonavir. Los pacientes resolvieron el cuadro clínico luego de 2-4 meses de suspensión de la fluticasona y permanecieron asintomáticos en el seguimiento

RESUMEN

The increase in life expectancy with the advent of highly effective antiretroviral therapy poses challenges in terms of toxicity and drug interactions. Exogenous Cushing syndrome by interaction between ritonavir and inhaled fluticasone in children diagnosed with human immunodeficiency virus infection and chronic pulmonary pathology is rare. So far, there are 20 cases reported. Three pediatric cases are reported, with a diagnosis of human immunodeficiency virus infection and chronic pulmonary pathology who presented exogenous Cushing syndrome with inhaled fluticasone at usual doses due to drug interaction between it and ritonavir. The patients resolved the clinical picture after 2-4 months of fluticasone suspension and remain asymptomatic in the follow-up.

RESUMEN

BACKGROUND: The Tip-of-the-Tongue (ToTs) state is considered a universal phenomenon and is a frequent cognitive complaint in old age. Previous cross-sectional studies have found that ToT measures successfully discriminate between cognitively unimpaired adults and adults with Mild Cognitive Impairment (MCI). The aim of this study was to identify longitudinal patterns of ToTs in individuals with subjective complaints and with MCI regarding progress of their cognitive status. METHOD: The study included 193 participants with subjective cognitive complaints (SCC) and 56 participants with MCI who completed a baseline and two follow-up assessments, with an interval of about 18 months between each assessment. Participants were classified into three groups by considering cognitive stability or deterioration from the baseline diagnosis: SCC-stable, MCI-stable and MCI-worsened. Participants performed a ToT task involving recognition and naming of famous people depicted in 50 photographs. Generalized Linear Mixed Models (GLMM) were used to model longitudinal changes in familiarity, feeling of knowing, semantic access, phonological access and verbal fluency. RESULTS: Phonological access differentiated MCI patients, stable and worsened, from adults with SCCs at all evaluation times. Phonological access declined over time in the three groups, without significant interactions between groups and time. DISCUSSION: This study provides the first longitudinal evidence of differences in ToT measures for adults with MCI. The findings indicate that phonological access measures successfully differentiated between the diagnostic groups. However, slopes remain irrespective of the diagnostic group and progression toward more advance stages of cognitive impairment.
