Pulmonary rehabilitation (PR) is recognized as a multidisciplinary intervention designed to reduce symptoms, improve functional status, and prevent acute exacerbations in patients with chronic obstructive pulmonary disease (COPD).

This study was aimed at evaluating the effects of a long-term PR program on the hospitalization rate and mortality of patients with severe and very severe COPD.

This was a prospective study where cohorts of 195 patients undergoing a PR program were followed up for 5 years. They were divided into 3 groups control (PR = 0 or < 3 months), partial adherence (PR > 6 and ≤ 18 months) and adherence (PR = 24 months). All patients were evaluated every 6 months (D0, D6, D12, D18 and D24, and mapped annually concerning hospitalizations and mortality). Data were analysed by medians and interquartile ranges, and Kruskal-Wallis nonparametric comparative tests were applied. Comparisons of time to first admission and time to death were made using the Kaplan-Meier estimators, and the facsively favourable clinical effects, thus reducing the frequency of hospitalizations and mortality in this population.
Women with gestational diabetes (GDM) and weight gain during pregnancy above recommended more often give birth to macrosomic children. The goal of this study was to evaluate the diagnostic accuracy of the modified formula for ultrasound assessment of fetal weight created in a pilot study using a similar specimen in comparison to the Hadlock-2 formula.

This is a prospective, cohort, applicative, observational, quantitative, and analytical study, which included 213 pregnant women with a singleton pregnancy, GDM, and pregnancy weight gain above recommended. Participants were consecutively followed in the time period between July 1st, 2016, and August 31st, 2020. Ultrasound estimations were made within three days before the delivery. Fetal weights estimated using both formulas were compared to the newborns' weights.

A total of 133 fetal weight estimations were made. In comparison to the newborns' weight modified formula had significantly smaller deviation in weight estimation compared to the Hadlock-2 formula, higher frequency of deviation within 5% of newborns weights (78.2% [95% CI=0.74-0.83] vs. 60.2%), smaller frequency of deviations from 5 to 10% (19.5 vs. 33.8%) and above 10%, which was even more significant among macrosomic children. There were 36/50 (72%) correctly diagnosed cases of macrosomia by modified and 33/50 (66%) by Hadlock-2 formula. Area under the curve (AUC) for the modified formula was 0.854 (95% CI=0.776-0.932), and for the Hadlock-2 formula 0.824 (95% CI=0.740-0.908). The positive predictive value of the modified formula was 81.81%, the negative 97.91%.

In cases of greater fetal weights, the modified formula showed greater precision.

Parents and clinicians of children with cancer can provide advice to improve communication that reflects lessons learned through experience. We aimed to identify categories of communication advice offered to parents of children with cancer from clinicians and other parents.

(1) Semi-structured interviews with 80 parents of children with cancer at three sites; (2) single-item, open-ended survey administered following 10 focus groups with 58 pediatric oncology clinicians at two sites. We asked participants for communication advice to parents, and analyzed responses using semantic content analysis.

Parents provided five categories of communication advice to other parents. Advocacy involved asking questions, communicating concerns, and speaking up for the child. Support involved pursuing self-care, seeking and accepting help, and identifying supportive communities. Managing information involved taking and organizing notes, remaining open to difficult truths, and avoiding inaccurate information. Partnership ient advocates could offer experience-informed advice to parents who are seeking information and support.The polycomb repressive complexes 1 and 2 (PRCs; PRC1 and PRC2) are conserved histone-modifying enzymes that often function cooperatively to repress gene expression. The PRCs are regulated by long noncoding RNAs (lncRNAs) in complex ways. On the one hand, specific lncRNAs cause the PRCs to engage with chromatin and repress gene expression over genomic regions that can span megabases. On the other hand, the PRCs bind RNA with seemingly little sequence specificity, and at least in the case of PRC2, direct RNA-binding has the effect of inhibiting the enzyme. Thus, some RNAs appear to promote PRC activity, while others may inhibit it. The reasons behind this apparent dichotomy are unclear. The most potent PRC-activating lncRNAs associate with chromatin and are predominantly unspliced or harbor unusually long exons. Emerging data imply that these lncRNAs promote PRC activity through internal RNA sequence elements that arise and disappear rapidly in evolutionary time. These sequence elements may function by interacting with common subsets of RNA-binding proteins that recruit or stabilize PRCs on chromatin.

Diagnosis of cutaneous lymphomas is challenging and requires high clinical suspicion and close collaboration between dermatologists, pediatric oncologists and pathologists. Skin involvement of non-Hodgkin lymphomas in children or adolescents can either be primary cutaneous or secondary due to an underlying nodal lymphoma. The most common primary cutaneous lymphomas encountered in children are of T-cell origin, with mycosis fungoides being the most prevalent cutaneous T-cell lymphoma, followed by CD30+ lymphoproliferative disorders. While cutaneous lymphomas share clinicopathologic characteristics between juvenile and adult forms, there are important differences in terms of clinical presentation, diagnosis and treatment. The hypopigmented variant of mycosis fungoides seems to be overrepresented in the pediatric age group. Prognosis and treatment of mycosis fungoides are stage dependent. The majority of children present with early-stage disease and respond well to topical corticosteroids and phototherapy.Primär kutane Lymphome sind extranodale T- oder B-Zell-Non-Hodgkin-Lymphome, die vorwiegend ältere Patienten betreffen, aber in allen Altersgruppen einschließlich der ersten Lebensjahre auftreten können. Die Diagnose kutaner Lymphome ist eine Herausforderung und erfordert einen hohen klinischen Verdacht sowie enge Zusammenarbeit zwischen Dermatologen, pädiatrischen Onkologen und Pathologen. Generell müssen primär kutane Lymphome von sekundär kutanen Lymphomen, welche meist von nodalen oder extranodalen Lymphomen ausgehen, unterschieden werden. Die häufigsten primär kutanen Lymphome im Kindesalter sind T-Zell Lymphome, wobei Mycosis fungoides das häufigste kutane T-Zell-Lymphom darstellt, gefolgt von CD30+ lymphoproliferativen Erkrankungen. Während klinisch-pathologische Merkmale kutaner Lymphome bei Jugendlichen und Erwachsenen ähnlich sind, gibt es wichtige Unterschiede bezüglich klinischer Präsentation, Diagnose und Behandlung. Die hypopigmentierte Variante der Mycosis fungoides scheint in der pädiatrischen Altersgruppe überrepräsentiert zu sein. Prognose und Behandlung der Mycosis fungoides sind stadienabhängig. Die Mehrheit der Kinder weist ein frühes Krankheitsstadium auf und spricht gut auf topische Kortikosteroide und Phototherapie an.
In der Primär- und Sekundärprävention von Berufsdermatosen werden Hautschutzprodukte eingesetzt, die eine präexpositionelle Schutzwirkung aufweisen sollen. Insbesondere finden sich auf dem Markt zahlreiche Produkte, die zum Einsatz bei Feuchtarbeit ausgelobt werden. Eine objektive Qualitätsbeurteilung dieser Produkte für Anwender ist auf Grund fehlender vergleichender Wirksamkeitsstudien oft nicht möglich.

In einer doppelblinden, randomisierten und kontrollierten In-vivo-Studie wurden sechs kommerzielle Hautschutzexterna in einem repetitiven Irritationsmodell untersucht. Sie wurden hinsichtlich ihrer präexpositionellen Schutzwirkung vor dem durch Natriumlaurylsulfat (SLS) induzierten irritativen Kontaktekzem mittels hautphysiologischer Methoden getestet. Es wurde ein Wirkindex anhand des transepidermalen Wasserverlustes (TEWL) gemäß des Protokolls der multizentrischen Studie des Forschungsprojektes FP275 der Deutschen Gesetzlichen Unfallversicherung DGUV berechnet.

Die untersuchten Externa zeigten eine Schutzwirkung gegen SLS im Vergleich zum unbehandelten Kontrollfeld, wiesen allerdings signifikante Wirkunterschiede auf. Die Auswertung der Nebenparameter Corneometrie und visueller Score erbrachte ebenfalls Unterschiede zwischen den Externa.

Die zwischen den untersuchten Externa festgestellten Unterschiede hinsichtlich der Wirkgüte ermöglichten eine Einteilung der Produkte, welche als Grundlage für die Auswahl geeigneter Schutzpräparate dienen kann.

Indirect methods targeting biomarkers constitute an alternative to extend detection time frames in doping control analyses. Gene expression analysis (i.e., transcriptomics) has already shown interesting results in both humans and equines for erythropoietin (EPO), growth hormone (GH), and anabolic androgenic steroid (AAS) misuses. read more In humans, circulating cell-free microRNAs in plasma were described as new potential biomarkers for control of major doping agent (MDA) abuses. The development of a quantitative polymerase chain reaction (qPCR) method allowing the detection of circulating miRNAs was carried out on equine plasma collected on different type of tubes (EDTA, lithium-heparin [LiHep]). Although analyzing plasma collected in EDTA tubes is a standard method in molecular biology, analyzing plasma collected in LiHep tubes is challenging, as heparin is a reverse transcription (RT) and a PCR inhibitor. Different strategies were considered, and attention was paid on both miRNAs extraction quality and detection sensitivity. The detection of endogenous circulating miRNAs was performed and compared between the different types of tubes. In parallel, homologs of human miRNAs characterized as potential biomarkers of doping were sought in equine databases. The miRNA eca-miR-144, described as potential erythropoiesis stimulating agents (ESAs) administration candidate biomarker was retained and assessed in equine post-administration samples. The results about the qPCR method development and optimization are exposed as well as the equine miRNAs detection. To our knowledge, this work is the first study and the proof of concept of circulating miRNAs detection in plasma dedicated to equine doping control.
