Unrestricted vs 3-day low-residue diet for colonoscopy preparation. Results of a feasibility randomized trial.

AIM: To compare the impact of an unrestricted diet with a 3-day low-residue diet before colonoscopy on bowel preparation quality. METHODS: A randomized, multicenter, researcher-blinded, parallel-group feasibility trial was conducted to assess the efficacy of an unrestricted diet versus a 3-day low-residue diet for colonoscopy preparation. Participants, aged 50 to 69, were enrolled in a colorectal cancer screening program with no factors linked to poor bowel cleansing. The Boston Bowel Preparation Scale was used to evaluate colon preparation during intubation and withdrawal. Secondary outcomes included bowel exploration time, adenoma and polyp detection rates, and preparation and diet tolerability. The trial is registered under Clinical Trials (NCT04664543). RESULTS: One hundred and two individuals (mean age 59.3 ± 5.5 years, 40.1% female) were randomly assigned to each diet. All participants in both groups achieved adequate preparation (Boston scores ≥ 2 in each segment). Complete adherence to preparation was observed in the majority of participants in both groups. No significant differences were noted between groups in withdrawal or cecal intubation times, or in adenoma detection rates. The unrestricted diet was better tolerated than the 3-day low-residue diet (82.5% vs. 32.3%). Preparation assessed during intubation was adequate in 82.5% of the unrestricted diet group and in 90.3% of the 3-day low-residue diet group. CONCLUSIONS: It is feasible to test the impact of an unrestricted diet for adequate bowel preparation. Comparable cleansing results were achieved, but the unrestricted diet showed better tolerability.

Limitation of life support treatments in Spanish Intensive Care Units: Analysis of the ETHICUS II study.

OBJECTIVE: The aim of this study is to describe the results of Spanish ICUs in ETHICUS II study. DESIGN: Planned substudy of patients from ETHICUS II study. SETTING: 12 Spanish ICU. PATIENTS OR PARTICIPANTS: Patients admitted to Spanish ICU who died or in whom a limitation of life-sustaining treatment (LLST) was decided during a recruitment period of 6 months. INTERVENTIONS: Follow-up of patients was performed until discharge from the ICU and 2 months after the decision of LLST or death. MAIN VARIABLES OF INTEREST: Demographic characteristics, clinical profile, type of decision of LLST, time and form in which it was adopted. Patients were classified into 4 categories according to the ETHICUS II study protocol: withholding or withdrawing life-sustaining therapy, active shortening of the dying process, failed cardiopulmonary resuscitation and patients with brain death. RESULTS: A total of 795 patients were analyzed; 129 patients died after CPR, 129 developed brain death. LLST was decided in 537 patients, 485 died in the ICU, 90.3%. The mean age was 66.19 years ± 14.36, 63.8% of male patients. In 221 (41%) it was decided to withdraw life-sustaining treatments and in 316 (59%) withholding life-sustaining treatments. Nineteen patients (2.38%) had advance living directives. CONCLUSIONS: The predominant clinical profile when LTSV was established was male patients over 65 years with mostly cardiovascular comorbidity. We observed that survival was higher in LLST decisions involving withholding of treatments compared to those in which withdrawal was decided. Spain has played a leading role in both patient and ICU recruitment participating in this worldwide multicenter study.

Restrictive diets are unnecessary for colonoscopy: Non-inferiority randomized trial.

Background and study aims In colonoscopy, preparation is often regarded as the most burdensome part of the intervention. Traditionally, specific diets have been recommended, but the evidence to support this policy is insufficient. The aim of this study was to evaluate the impact of the decision not to follow a restrictive diet on bowel preparation and colonoscopy outcomes. Patients and methods This was a multicenter, controlled, non-inferiority randomized trial with FIT-positive screening colonoscopy. The subjects were assigned to follow the current standard (1-day low residue diet [LRD]) or a liberal diet. The allocation was balanced for the risk of inadequate cleansing using the Dik et al. score. All participants received the same instructions for morning colonoscopy preparation. The primary outcome was the rate of adequate preparations as defined by the Boston Bowel Preparation Scale. Secondary outcomes included tolerability and measures of colonoscopy performance and quality. Results A total of 582 subjects were randomized. Of these, 278 who received the liberal diet and 275 who received the 1-day LRD were included in the intent-to-treat analysis. Non-inferiority was demonstrated with adequate preparation rates of 97.8% in the 1-day LRD and 96.4% in the liberal diet group. Tolerability was higher with the liberal diet (94.7% vs. 83.2%). No differences were found with respect to cecal intubation time, aspirated volume, or length of the examination. Global and right colon average adenoma detection rates per colonoscopy were similar. Conclusions The liberal diet was non-inferior to the 1-day LRD, and increased tolerability. Colonoscopy performance and quality were not affected. (NCT05032794).

Blind date: female fossorial amphisbaenians prefer scent marks of large and healthy males.

Selecting a good mate is a decision with important fitness consequences. For this reason, mate choice has promoted the evolution of sexual ornaments signaling the quality of an individual. In fossorial animals, inhabiting visually restricted underground environments, chemical senses should be very important for mate choice. We examined whether sexual chemical signals (substrate scent marks) produced by males of the Iberian worm lizard, Blanus cinereus, a strictly fossorial blind amphisbaenian, provide information to females on morphological traits and health state. We administered corticosterone (CORT) to males simulating a continuous stressor affecting their health. Females preferred settling at sites scent-marked by males in comparison with similar sites with female scent or unmarked sites, but the attractiveness of males' scent differed between individuals. Females preferred scent marks of larger/older males and with a higher immune response, while their body condition and CORT treatment were unrelated to female preferences. Chemical analyses showed that proportions of some compounds in precloacal secretions of males (used to produce scent marks) were correlated with the morphological (body size) and health state (immune response and body condition, but not CORT treatment) of these males. These results suggest that females may make site-selection decisions based on assessing the chemical characteristics of males' scent marks, which were reliably related to some of the traits of the male that produced the scent. Therefore, females might use chemical senses to increase the opportunities to find and mate with males of high quality, coping with the restrictions of the subterranean environment.

Phase angle and rectus femoris cross-sectional area as predictors of severe malnutrition and their relationship with complications in outpatients with post-critical SARS-CoV2 disease.

Background and aims: The diagnosis of malnutrition in post-critical COVID-19 patients is challenging as a result of the high prevalence of obesity, as well as the variability and previously reported inconsistencies across currently available assessment methods. Bioelectrical impedance vector analysis (BIVA) with phase angle (PhA) and nutritional ultrasound (NU®) are emerging techniques that have been proven successful in assessing body composition with high precision in previous studies. Our study aims to determine the performance and usefulness of PhA and rectus femoris cross-sectional area (RF-CSA) measurements in assessing body composition as part of the full routine morphofunctional assessment used in the clinical setting, as well as their capacity to predict severe malnutrition and to assess complications and aggressive therapy requirements during recent intensive care unit (ICU) admission, in a cohort of post-critically ill COVID-19 outpatients. Methods: This prospective observational study included 75 post-critical outpatients who recovered from severe COVID-19 pneumonia after requiring ICU admission. Correlations between all the morphofunctional parameters, complications, and aggressive therapy requirements during admission were analyzed. Multivariate logistic regression analysis and ROC curves were provided to determine the performance of NU® and PhA to predict severe malnutrition. Differences in complications and aggressive therapy requirements using the cutoff points obtained were analyzed. Results: In total, 54.7% of patients were classified by Subjective Global Assessment (SGA) as SGA-B and 45.3% as SGA-C, while 78.7% met the Global Leadership Initiative of Malnutrition (GLIM) criteria. PhA correlates positively with body cell mass/height (BCM/h) (r = 0.74), skeletal muscle index (SMI) (r = 0.29), RF-CSA (r = 0.22), RF-Y axis (r = 0.42), and handgrip strength (HGS) assessed using dynamometry (r = 0.42) and the Barthel scale (r = 0.29) and negatively with ICU stay (r = -0.48), total hospital stay (r = -0.57), need for invasive mechanical ventilation (IMV) (r = -0.39), days of IMV (r = -0.41), need for tracheostomy (r = -0.51), and number of prone maneuvers (r = -0.20). RF-CSA correlates positively with BCM/h (r = 0.41), SMI (r = 0.58), RF-Y axis (r = 0.69), and HGS assessed using dynamometry (r = 0.50) and the Barthel scale (r = 0.15) and negatively with total hospital stay (r = -0.22) and need for IMV (r = -0.28). Cutoff points of PhA < 5.4° and standardized phase angle (SPhA) < -0.79 showed good capacity to predict severe malnutrition according to SGA and revealed differences in ICU stay, total hospital stay, number of prone maneuvers, need for IMV, and need for rehabilitation, with statistical significance (p < 0.05). An RF-CSA/h < 2.52 cm2/m (for men) and <2.21 cm2/m (for women) also showed good performance in predicting severe malnutrition and revealed differences with statistical significance (p < 0.05) in ICU stay and total hospital stay. Conclusion: More than 75% of the post-critical COVID-19 survivors had malnutrition, and approximately half were obese. PhA, SPhA, RF-CSA, and RF-CSA/h, when applied to the assessment of body composition in post-critical COVID-19 patients, showed moderate-to-high correlation with other morphofunctional parameters and good performance to predict severe malnutrition and to assess complications and aggressive therapy requirements during ICU admission. Besides being readily available methods, BIVA and NU® can help improve the morphofunctional assessment of malnutrition in post-critical COVID-19 survivors; however, more studies are needed to assess the performance of these methods in other populations.

Demographic, functional and clinical characteristics in hip fracture patients according to mental status of Spanish National Hip Fracture Registry.

OBJECTIVE: To describe the differences according to mental status at admission on the care process and 30-day outcomes in hip fracture patients, mainly regarding the use of rehabilitation resources and anti-osteoporotic medication, by analysing data from the Spanish National Hip Fracture Registry (RNFC, "Registro Nacional de Fracturas de Cadera" in Spanish). METHODS: We analysed prospectively collected data from a cohort of patients admitted participating in the Spanish National Hip Fracture Registry (RNFC) in 76 Spanish hospitals between 2017 and 2019. We classified participants using Short Portable Mental Status Questionnaire (SPMSQ), defining two groups: patients with ≤2 SPMSQ score and patients with >2 SPMSQ score. RESULTS: Of 21,254 patients was recorded SPMSQ in 17,242 patients, 9052 were >2 SPMSQ score (52.6%). These were older (87.7 vs. 85.3 years; p<0.001), had worse mobility (no-independent walking ability 26.0% vs. 4.5%; p<0.001) and were more likely to be living in nursing homes (35.3% vs. 9.6%; p<0.001). They were more likely to be treated nonoperatively (3.8% vs. 1.5%; p>0.001), less early mobilisation (57.5% vs. 68.9%; p<0.001) and suffered higher in-hospital mortality (5.2% vs. 2.7%; p<0.001). At discharge, they received less anti-osteoporotic medication (37.9% vs. 48.9%; p<0.001) and returned home less often (29.8%% vs. 51.2%; p<0.001). One month after fracture, patients with >2 SPMSQ score had poorer mobility (no-independent walking ability 44.4% vs. 24.9%; p<0.001) and were newly institutionalised in a nursing home more (12.6% vs. 12.0%; p<0.001) and were more likely to die by one-month post-fracture (9.5% vs. 4.6%; p<0.001). CONCLUSION: RNFC patients with >2 SPMSQ score were more vulnerable and had poorer outcomes than patients with ≤2 SPMSQ score, suggesting that they need specialised care in-hospital and in the recovery phase.

Amivantamab Compared with Real-World Physician's Choice after Platinum-Based Therapy from a Pan-European Chart Review of Patients with Lung Cancer and Activating EGFR Exon 20 Insertion Mutations.

Patients with advanced non-small cell lung cancer (NSCLC) with epidermal growth factor receptor gene (EGFR) Exon 20 insertions (Exon20ins) at the second line and beyond (2L+) have an unmet need for new treatment. Amivantamab, a bispecific EGFR- and MET-targeted antibody, demonstrated efficacy in this setting in the phase 1b, open-label CHRYSALIS trial (NCT02609776). The primary objective was to compare the efficacy of amivantamab to the choices made by real-world physicians (RWPC) using an external control cohort from the real-world evidence (RWE) chart review study, CATERPILLAR-RWE. Adjustment was conducted to address differences in prognostic variables between cohorts using inverse probability weighting (IPW) and covariate adjustments based on multivariable regression. In total, 114 patients from CHRYSALIS were compared for 55 lines of therapy from CATERPILLAR-RWE. Baseline characteristics were comparable between the amivantamab and IPW-weighted RWPC cohorts. For amivantamab versus RWPC using IPW adjustment, the response rate ratio for the overall response was 2.14 (p = 0.0181), and the progression-free survival (PFS), time-to-next-treatment (TTNT) and overall survival (OS) hazard ratios (HRs) were 0.42 (p < 0.0001), 0.47 (p = 0.0063) and 0.48 (p = 0.0207), respectively. These analyses provide evidence of clinical and statistical benefits across multiple outcomes and adjustment methods, of amivantamab in platinum pre-treated patients with advanced NSCLC harboring EGFR Exon20ins. These results confirm earlier comparisons versus pooled national registry data.

Recurrent reactive infectious mucocutaneous eruption (RIME) secondary to Chlamydophila pneumoniae infection in an adult.

The terminology surrounding the clinical syndrome characterized by acute mucositis with minimal skin involvement has been a subject of debate over time. In recent years, terms such as mycoplasma-induced rash and mucositis and reactive infectious mucocutaneous eruption (RIME) have been introduced to encompass milder mucocutaneous diseases associated with respiratory infections, with implications for management and prognosis. We report the first case of recurrent RIME associated with Chlamydophila pneumoniae infection in an adult patient. RIME is likely underreported due to misclassification and a lack of testing for potential pathogens. Early recognition of recurrent RIME is of particular interest from the patient's perspective to reduce the frequency and duration of hospital admissions.

Comparison of the Latin America Regulation Landscape and International Reference Health Authorities to Hasten Drug Registration and Clinical Research Applications.

INTRODUCTION: Promptly providing new drugs to fulfill unmet medical needs requires changes in drug development and registration processes. Health Authorities (HAs) considered as reference due to their experience and acknowledgement (Food and Drug Administration [FDA] among others) already consider innovative clinical trial (CT) designs and flexible approval procedures, but Latin America (LATAM) regulations are still far. A comparison was performed to identify gaps. MATERIALS AND METHODS: CT requirements for drug Marketing Authorization Application (MAA) and CT approval regulations were compared between LATAM and reference HAs (FDA/European Medicines Agency [EMA]/Health-Canada/Swissmedic/Therapeutic Goods Administration [TGA]/Pharmaceuticals and Medical Devices Agency [PMDA]), as of August 2022. Procedure included reference HAs regulations review, item selection, identification in LATAM regulations, and International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) guidelines (ICH-E6[R2]/ICH-E8[R1]) implementation revision. RESULTS: For MAA, specific application requirements or ICH guideline M4(R4) on common technical document (CTD) adoption are generally stated, and phase-I/III performance is mandatory (explicitly/implicitly). Faster patient access procedures are infrequent: Priority-drug programs, conditional authorizations, or expedited procedures are scarce or non-existent. Regulatory reliance procedures are adopted through different pathways. Regarding CT approval, innovative/complex CT designs are not prohibited but usually omitted. Some countries implemented adapted CT conducting during the COVID-19 pandemic. Early scientific advice meetings (HA-sponsor) are occasionally considered. Most countries are not formally ICH-joined. CONCLUSIONS: LATAM regulations must adapt to new regulatory standards (FDA/EMA/ICH) through implementation of frequent updates, reliance/expedited procedures, early HA-sponsor interactions, innovative/complex CTs, mandatory phase-III reaching elimination, and decentralized elements for CT conducting.

Gender inequity in the medical profession: the women doctors in Spain (WOMEDS) study.

BACKGROUND: The long-standing underrepresentation of women in leadership positions in medicine is well-known, but poorly documented globally. There is some evidence of the gender gap in academia, medical society leadership, or specific problems in some specialties. However, there are no investigations analyzing all medical specialties together and reporting the glass ceiling from a 360º perspective that includes positions in academia, research, professional organizations, and clinical activity. Additionally, the majority of studies have a US perspective, and we wonder if the perspective of a European country might be different. The WOmen in MEDicine in Spain (WOMEDS) project ( https://womeds.es ) aims to describe and characterize, in a systematic and detailed way, the gender bias in the medical profession in Spain in order to monitor its evolution over time and contribute to prioritizing gender policies. METHODS: We retrieved data for the calendar years 2019-2021 from several sources and selected surveys. We built four groups of indicators to describe leadership positions in the medical profession: (i) leadership in healthcare according to specialty and region; (ii) leadership in scientific and professional bodies; (iii) academic career; and (iv) leadership in clinical research activity. As a summary measure, we reported the women ratios, calculated as the percentage of women in specific top positions divided by the percentage of women in the relevant population. RESULTS: We found gender inequity in leadership positions in all four settings. During the observed period, only 27.6% of the heads of departments in hospitals were women compared to 61.1% of women in medical staff. Ten of the 46 medical societies grouped in the Spanish Federation of Medical Societies (FACME) (21.7%) had a women president at some point during the study period, and only 4 annual congresses had ratios of women speakers higher than 1. Women were over-represented in the lower positions and underrepresented in the top academic ones. Only 26% and 27%, respectively, of the heads of departments and deans were women. The applications for public funding for research projects are led by women only in 45% of the cases, and the budget granted to women in public calls was 24.3% lower than that of men. CONCLUSION: In all the areas analyzed, the leadership positions are still mostly occupied by men despite the feminization of medicine in Spain. The severe gender inequity found calls for urgent interventions within a defined time horizon. Such measures must concern all levels, from national or regional regulation to changes in organizational culture or incentives in specific organizations.

RESUMEN EN ESPAÑOL: ANTECEDENTES: La prolongada infrarrepresentación de las mujeres en los puestos de liderazgo en medicina es bien conocida, pero está poco documentada de forma global. Hay evidencia sobre la brecha de género en la universidad, en el liderazgo en sociedades médicas o en determinadas especialidades. Sin embargo, no hay investigaciones que analicen el techo de cristal de cada una de las especialidades médicas desde una perspectiva 360º que incluya el liderazgo en la universidad, en la investigación con fondos públicos, en la representación en sociedades científicas y colegios profesionales y en la actividad clínica. Además, la mayoría de los estudios tienen una perspectiva estadounidense y nos preguntamos si la perspectiva de un país europeo podría ser diferente. El proyecto Mujeres en Medicina en España (WOMEDS) ( https://womeds.es ) tiene como objetivo describir y caracterizar de forma sistemática y detallada sesgo de género en la profesión médica en España, para monitorizar su evolución en el tiempo y contribuir a priorizar las políticas de género. MéTODOS: Construimos cuatro grupos de indicadores sobre liderazgo de mujeres médicos: (i) en la asistencia sanitaria; (ii) en las organizaciones científicas y profesionales; (iii) carrera académica, y; and (iv) l en la investigación basándonos en datos públicos y resultados de encuestas propias s referidas a los años 2019­2021. Como medida de análisis, calculamos los ratios de mujeres, definidos como el porcentaje de mujeres en puestos altos específicos dividido por el porcentaje de mujeres en la población relevante. RESULTADOS: Encontramos un sesgo de género en los cuatro ámbitos. Durante el periodo observado, solo el 27.6% de los jefes de servicio de los hospitales eran mujeres, frente al 61.1% de mujeres en la plantilla. Diez de las 46 sociedades médicas agrupadas en la Federación de Asociaciones Científico Médicas Españolas (FACME) (21.7%) tuvieron una mujer como presidente en algún momento del periodo de estudio y sólo 4 congresos anuales tenían ratios de mujeres ponentes superiores a 1. Las mujeres estaban sobrerepresentadas en los cargos inferiores e infrarrepresentadas en los cargos académicos superiores. Sólo el 26% y el 27%, respectivamente, de los jefes de departamento y decanos eran mujeres. La solicitud de proyectos de investigación con financiación pública fue liderada por mujeres en un 45% de los casos y la financiación media de los proyectos concedidos a las mujeres fue un 24.3% inferior a la de los hombres. CONCLUSIóN: En todos los ámbitos analizados, las posiciones de liderazgo siguen siendo mayoritariamente ocupada por varones a pesar de la feminización de la medicina. Para cambiar esto, será necesario tomar medidas, tanto regulatorias -a nivel nacional y nacional regional como promover cambios en la cultura organizativa o en los incentivos en organizaciones concretas.

Evaluating the functional, sexual and seasonal variation in the chemical constituents from feces of adult Iberian wolves (Canis lupus signatus).

Chemical signals deposited in feces play an important role in intraspecific and interspecific communication of many mammals. We collected fresh feces of adult wolves from wild breeding groups. All samples visually identified as belonging to wolves were subsequently identified to species level by sequencing a small fragment of mtDNA and sexed typing DBX6 and DBY7 sex markers. Using gas chromatography-mass spectrometry (GC-MS), we identified 56 lipophilic compounds in the feces, mainly heterocyclic aromatic organic compounds, such as indole or phenol, but also steroids, such as cholesterol, carboxylic acids and their esters between n-C4 and n-C18, aldehydes, alcohols and significant quantities of squalene and α-tocopherol, which would increase the chemical stability of feces on humid substrates. There was variability in the number and proportions of compounds between sexes, which could be indicative of their function as chemical signals. We also found variability in different reproductive states, especially in odorous compounds, steroids and α-tocopherol. Feces with a presumed marking function had higher proportions of α-tocopherol and steroids than feces with non-marking function. These compounds could be involved in intragroup and intergroup communication of wolves and their levels in feces could be directly related with the wolf's sex and physiological and reproductive status.

Repercusión de la restricción de visitas familiares por la pandemia en la evolución clínica del paciente geriátrico hospitalizado / Impact of the restriction of family visits due to the pandemic on the clinical evolution of the hospitalized geriatric patient

La restricción de acompañamiento de familiares a pacientes hospitalizados tiene consecuencias para el paciente, la familia y los profesionales. En este estudio nos planteamos como objetivo analizar la opinión de los profesionales sanitarios sobre la presencia familiar en los cuidados y recuperación del paciente geriátrico hospitalizado. Se realizó un estudio descriptivo observacional multicéntrico desarrollado mediante una encuesta dirigida a profesionales de hospitales de Madrid. Respondieron 314 profesionales (43,6% enfermeras, 26,1% auxiliares de enfermería y 15,6% médicos) de diferentes hospitales. El 80% (IC 95%: 75-84%) afirmaron que la restricción de las visitas dificultaba la recuperación del paciente, y el 84% (IC 95%: 80-88%) que los cuidados familiares no se pueden suplir por los profesionales, aunque sí mejorar mediante formación y aumento de personal (91%). El 70% piensan que cuando los pacientes están solos, comen y beben menos, sufren más broncoaspiración y delirium, y mayor dificultad para la higiene y la movilización. Los profesionales sanitarios reconocieron que los cuidados que desarrollan los familiares de los pacientes facilitan su recuperación. (AU)

The restriction of family accompaniment of hospitalised patients has consequences for the patient, family and professionals. The aim of this study was to analyse the opinion of healthcare professionals on the family presence in the care and recovery of hospitalised geriatric patients. A descriptive, observational, multicentre study was carried out by means of a survey addressed to professionals from hospitals in Madrid. A total of 314 professionals (43.6% nurses, 26.1% nursing assistants, 15.6% doctors) from different hospitals responded. Eighty percent (95%CI: 75%-84%) stated that the restriction of visits hindered the patient's recovery and 84% (95%CI: 80%-88%) stated that the family care cannot be substituted by professionals, although it can be improved through training and increased staffing (91%). Seventy percent think that when patients are alone, they eat and drink less, suffer more bronchial aspiration and delirium, and have greater difficulty in hygiene and mobilisation. Healthcare professionals recognised that the care provided by patients’ relatives facilitates their recovery. (AU)

Intersexual and body size-related variation in chemical constituents from feces and cloacal products involved in intraspecific communication of a fossorial amphisbaenian.

Background: Many animals rely on chemical cues for intraspecific communication. This is especially important in fossorial animals because visual restrictions of the underground environment limit the opportunities for visual communication. Previous experiments showed the ability of the amphisbaenian Trogonophis wiegmanni to discriminate between several categories of conspecifics based on chemical cues alone. However, in contrast with many other reptile species, T. wiegmanni does not have external secretory glands, but uses uncharacterized secretions from the cloaca in intraspecific chemosensory communication. Methods: Using gas chromatography-mass spectrometry (GC-MS), we analyzed the lipophilic compounds from feces and cloacal products freshly extracted from the cloaca of male and female T. wiegmanni. We identified and estimated relative proportions of the compounds found, and tested for intersexual and body-size related differences. Results: We found a total of 103 compounds, being some steroids (mainly cholesterol and cholestanol), some alkanes and squalene the most abundant and frequent. Further, we found intersexual differences, with males, especially larger ones, having higher proportions of several alkanes between C13 and C24 and of squalene than females, which had higher proportions of several steroids and also of nonacosane and methylnonacosane than males. We compared these findings with secretions of other animals and discuss the potential role of these compounds and their variations in intraspecific communication of amphisbaenians.

Clinical and Demographic Characteristics of Centenarians versus Other Age Groups Over 75 Years with Hip Fractures.

Objective: The primary objective was to describe the clinical characteristics, management, and outcomes of centenarians with fragility hip fracture and compare them to other age groups. The secondary objective was to determine the variables associated with length of stay, in-hospital mortality and 30-day mortality. Materials and Methods: This is a secondary analysis of the Spanish National Hip Fracture Registry. We included patients ≥75 years admitted for fragility hip fractures in 86 Spanish hospitals between 2017 and 2019, dividing the sample into four age groups. The variables studied were baseline characteristics, type of fracture, management, length of stay, in-hospital mortality and 30-day mortality. Results: We included 25,938 patients (2888 were 75-79 years old; 14,762 octogenarians; 8,035 nonagenarians and 253 centenarians). Of the centenarians, 83% were women, 33% had severe dementia, 9% had severe dependency and 36% lived in residential care homes. Six out of ten had intertrochanteric fracture. Length of hospital stay was 8.6 days; in-hospital mortality was 10.3% and 30-day mortality 20.9%. Older age groups had more women, severe functional dependency, severe dementia, intertrochanteric fracture, living in care facilities and being discharged to nursing care. They had less frequent early mobilization, osteoporosis treatment and discharge to rehabilitation units. In-hospital and 30-day mortality were higher with increasing age. In centenarians, time to surgery >48 hours was independently associated with length of stay (correlation coefficient 3.99 [95% CI: 2.35-5.64; p<0.001]) and anaesthetic risk, based on an ASA score of V, was related to 30-day mortality (ASA score II [OR 0.25, 95% CI: 0.09-0.70; p=0.009] and ASA score III [OR 0.43, 95% CI: 0.19-0.96; p=0.039]). Conclusion: Centenarians had different clinical characteristics, management and outcomes. Although centenarians had worse outcomes, nearly 4 out of 5 centenarians were alive one month after surgery.

[Impact of the restriction of family visits due to the pandemic on the clinical evolution of the hospitalized geriatric patient]. / Repercusión de la restricción de visitas familiares por la pandemia en la evolución clínica del paciente geriátrico hospitalizado.

The restriction of family accompaniment of hospitalised patients has consequences for the patient, family and professionals. The aim of this study was to analyse the opinion of healthcare professionals on the family presence in the care and recovery of hospitalised geriatric patients. A descriptive, observational, multicentre study was carried out by means of a survey addressed to professionals from hospitals in Madrid. A total of 314 professionals (43.6% nurses, 26.1% nursing assistants, 15.6% doctors) from different hospitals responded. Eighty percent (95%CI: 75%-84%) stated that the restriction of visits hindered the patient's recovery and 84% (95%CI: 80%-88%) stated that the family care cannot be substituted by professionals, although it can be improved through training and increased staffing (91%). Seventy percent think that when patients are alone, they eat and drink less, suffer more bronchial aspiration and delirium, and have greater difficulty in hygiene and mobilisation. Healthcare professionals recognised that the care provided by patients' relatives facilitates their recovery.

Post-Intensive Care Unit Multidisciplinary Approach in Patients with Severe Bilateral SARS-CoV-2 Pneumonia.

Background: Short and long-term sequelae after admission to the intensive care unit (ICU) for coronavirus disease 2019 (COVID-19) are to be expected, which makes multidisciplinary care key in the support of physical and cognitive recovery. Objective: To describe, from a multidisciplinary perspective, the sequelae one month after hospital discharge among patients who required ICU admission for severe COVID-19 pneumonia. Design: Prospective cohort study. Environment: Multidisciplinary outpatient clinic. Population: Patients with severe COVID-19 pneumonia, post- ICU admission. Methods: A total of 104 patients completed the study in the multidisciplinary outpatient clinic. The tests performed included spirometry, measurement of respiratory muscle pressure, loss of body cell mass (BCM) and BCM index (BCMI), general joint and muscular mobility, the short physical performance battery (SPPB or Guralnik test), grip strength with hand dynamometer, the six-minute walk test (6-MWT), the functional assessment of chronic illness therapy-fatigue scale (FACIT-F), the European quality of life-5 dimensions (EQ-5D), the Barthel index and the Montreal cognitive assessment test (MoCA). While rehabilitation was not necessary for 23 patients, 38 patients attended group rehabilitation sessions and other 43 patients received home rehabilitation. Endpoints: The main sequelae detected in patients were fatigue (75.96%), dyspnoea (64.42%) and oxygen therapy on discharge (37.5%). The MoCA showed a mean score compatible with mild cognitive decline. The main impairment of joint mobility was limited shoulder (11.54%) and shoulder girdle (2.88%) mobility; whereas for muscle mobility, lower limb limitations (16.35%) were the main dysfunction. Distal neuropathy was present in 23.08% of patients, most frequently located in lower limbs (15.38%). Finally, 50% of patients reported moderate limitation in the EQ-5D, with a mean score of 60.62 points (SD 20.15) in perceived quality of life. Conclusions: Our findings support the need for a multidisciplinary and comprehensive evaluation of patients after ICU admission for COVID-19 because of the wide range of sequelae, which also mean that these patients need a long-term follow-up. Impact on clinical rehabilitation: This study provides data supporting the key role of rehabilitation during the follow-up of severe patients, thus facilitating their reintegration in society and a suitable adaptation to daily living.

Psychological Consequences of Fear of COVID-19: Symptom Analysis of Triggered Anxiety and Depression Disorders in Adolescents and Young Adults.

Among the innumerable consequences of the pandemic caused by COVID-19 are those of a psychological nature, among which we find fear. For this reason, it is important to carry out research on the fear of contagion and its behavior, especially in the population as a whole, and the consequences that these facts entail. The present study examines the fear of contagion and illness by COVID-19 and its relationship with symptoms of anxiety disorders and depression in a total of 1370 participants aged 16 to 29 years. The results indicate that fear of COVID-19, fear of death from COVID-19 infection, and concern that family members and/or friends will be infected with COVID-19 are predictors of symptoms related to depressive disorder. elderly and social phobia.
