Die Analyse von und die Reflexion über Unterricht sind zentrale Elemente universitärer Lehrkräftebildung. Dabei kann sowohl in der Lehre als auch in der Forschung begriffliche Heterogenität bzgl. Reflexion konstatiert werden. Auch fehlt eine klare Abgrenzung zwischen Analyse und Reflexion von Unterricht. Aufbauend auf der Konzeption des Selbstbezugs als ein zentrales Unterscheidungsmerkmal wird mittels eines quasi-experimentellen Prä-Post-Interventions-Kontrollgruppendesigns geprüft, inwiefern sich Unterrichtsanalysen von Unterrichtsreflexionen in ihren Auswirkungen auf die professionelle Unterrichtswahrnehmung (PUW) und die klassenführungsbezogene Selbstwirksamkeit (SW) unterscheiden. An einer Stichprobe von 194 angehenden Lehrkräften im Master of Education einer Hochschule kann gezeigt werden, dass Unterrichtsanalyse und -reflexion vergleichbar positive Effekte auf die PUW zeigten (besser als eine Kontrollgruppe ohne spezifische Intervention). Allerdings zeigt die Reflexionsgruppe eine stärkere Zunahme klassenführungsbezogener SW im Vergleich zu den anderen beiden Gruppen. Die Ergebnisse deuten somit darauf hin, dass durch den expliziten Selbstbezug selbstgerichtete Kognitionen verstärkt thematisiert werden und damit zusätzliche Aspekte professioneller Kompetenz adressiert werden können.
Hintergrund
Ein Hauptziel der Versorgung von Patient*innen mit Cochlea-Implantat (CI) ist die Verbesserung des Sprachverstehens. Einer der Zielparameter ist die Sprachverständlichkeit in Ruhe. Die Versorgungsergebnisse lassen jedoch eine sehr große Variabilität erkennen, welche bislang nur unzureichend erklärt werden konnte. Ziel dieser nichtinterventionellen retrospektiven Studie war die Aufklärung dieser Variabilität. Dies erfolgte anhand einer ausgewählten Population von Patient*innen, bei der die Ätiologie keinen negativen Einfluss auf die postoperative Sprachverständlichkeit erwarten ließ.
Material und Methoden
Es wurden die audiometrischen Befunde der CI-Folgetherapie von 28 erwachsenen Patient*innen nach 6 Monaten CI-Erfahrung ausgewertet. Diese wurden in Relation zur präoperativen audiometrischen Untersuchung gesetzt und hinsichtlich eines unlängst publizierten Prädiktionsmodells für das postoperative Einsilberverstehen ausgewertet.
Ergebnisse
Durch Einschluss der postoperativen Hörfeldskalierung und des Hörverlusts für Zahlen in das Modell lassen sich 55 % der Variabilität in den Versorgungsergebnissen bzgl. des Einsilberverstehens erklären.
Schlussfolgerung
Die Ergebnisse dieser Studie legen nahe, dass ein Großteil der Ursachen für die Variabilität der Versorgungsergebnisse durch systematische postoperative audiometrische Kontrollen erfasst werden kann. Aus diesen Ergebnissen können sich unmittelbare Schlussfolgerungen für die Anpassungen der CI-Systeme ziehen lassen. Inwieweit diese jedoch von den einzelnen Patient*innen akzeptiert werden und somit zu einer Verbesserung der Befundlage führen, muss Gegenstand weiterer, möglichst prospektiver Studien sein.
Hintergrund
Die Zertifizierung von Zentren für Beatmungsentwöhnung in der neurologisch-neurochirurgischen Frührehabilitation (NNFR) durch die Deutsche Gesellschaft für Neurorehabilitation (DGNR) ist seit dem 01.10.2021 möglich.
Ziel der Arbeit
Die Ergebnisse der Zertifizierung von Einrichtungen im ersten Jahr nach Aufnahme des Verfahrens werden vorgestellt.
Material und Methoden
Im Rahmen der Zertifizierung werden 28 Kriterien geprüft, darunter eine Reihe mandatorisch zu erfüllender Charakteristika der Einrichtung. Die Kriterien gliedern sich in Strukturkriterien (i = 7), Diagnostikkriterien (i = 6), Personalkriterien (i = 3), Kriterien der internen Organisation (i = 7) und Qualitätsmanagementkriterien (i = 5).
Ergebnisse
Insgesamt 13 Zentren wurden im ersten Jahr zertifiziert, die zusammen über 283 Betten zur Beatmungsentwöhnung („weaning“) in der NNFR verfügen und im Jahr vor der Zertifizierung 2278 Personen im Weaning betreuten, im Median pro Einrichtung 134 (Bereich [Min-Max] 44–414). Nur selten war das Weaning nicht erfolgreich, sodass vor Entlassung auf eine Heimbeatmung eingestellt werden musste (invasive Heimbeatmung Median pro Einrichtung 10 Personen, Bereich 2–25; nichtinvasive Heimbeatmung Median 0 Personen, Bereich 0–57). Festgestellt wurde ein hohes Maß an Prozess- und Strukturqualität in den zertifizierten Zentren: Über alle Prüfbereiche hinweg waren die Prüfkriterien zu allermeist erfüllt (Median Erfüllungsgrad 86 %) bzw. erfüllt mit von den Auditor*innen dokumentierten Verbesserungspotenzialhinweisen (Median 11 %).
Schlussfolgerung
Erfolgreiches Weaning in der NNFR und ein hohes Maß an Prozess- und Strukturqualität lassen sich anhand der Zertifizierungsergebnisse der Zentren belegen, die diesen integrativen Ansatz bei der Beatmungsentwöhnung verfolgen.
This text is designed to give the reader a helping hand in writing a scientific paper. It provides generic advice on ways that a scientific paper can be improved. The focus is on the following ethical and non-technical issues: (1) when to start writing, and in what language; (2) how to choose a good title; (3) what should be included in the various sections (abstract, introduction, experimental, results, discussion, conclusions, and supporting information (supplementary material); (4) who should be considered as a co-author, and who should be acknowledged for help; (5) which journal should be chosen; and (6) how to respond to reviewers’ comments. Purely technical issues, such as grammar, artwork, reference styles, etc., are not considered.
We consider Walsh’s conformal map from the exterior of a compact set E ⊆ C onto a lemniscatic domain. If E is simply connected, the lemniscatic domain is the exterior of a circle, while if E has several components, the lemniscatic domain is the exterior of a generalized lemniscate and is determined by the logarithmic capacity of E and by the exponents and centers of the generalized lemniscate. For general E, we characterize the exponents in terms of the Green’s function of Ec. Under additional symmetry conditions on E, we also locate the centers of the lemniscatic domain. For polynomial pre-images E = P−1(Ω) of a simply-connected infinite compact set Ω, we explicitly determine the exponents in the lemniscatic domain and derive a set of equations to determine the centers of the lemniscatic domain. Finally, we present several examples where we explicitly obtain the exponents and centers of the lemniscatic domain, as well as the conformal map.
Purpose
Mixing with liquids or soft foods is a common procedure to improve acceptability of oral medicines in children but may affect drug stability and the in vivo performance of the administered drug product. The aim of the present study was to obtain an overview of the variability of critical attributes of commonly used vehicles and to identify which vehicle characteristics need to be considered when developing in vitro methods for evaluating product quality.
Methods
One product of each vehicle listed in the FDA draft guidance “Use of Liquids and/or Soft Foods as Vehicles for Drug Administration” was analyzed with regard to composition, calorific content and physicochemical properties.
Results
The studied vehicles show wide variability, both in composition and physicochemical properties. No correlation was observed between vehicle composition and physicochemical properties. Comparison of results of the present study with previously published data also provided variability in physicochemical properties within individual vehicle types.
Conclusions
To identify acceptable (qualified) vehicles for global drug product labeling, it is important that the vehicles selected for in vitro compatibility screening reflect the variability in composition and essential physicochemical properties of the vehicles recommended on the product label, rather than relying on results obtained with a single vehicle of each type. Future activities will focus on the development of standardized dosing vehicles that can represent key vehicle characteristics in all their variability to ensure reliable risk assessment.
Marine algae produce complex polysaccharides, which can be degraded by marine heterotrophic bacteria utilizing carbohydrate-active enzymes. The red algal polysaccharide porphyran contains the methoxy sugar 6-O-methyl-D-galactose (G6Me). In the degradation of porphyran, oxidative demethylation of this monosaccharide towards D-galactose and formaldehyde occurs, which is catalyzed by a cytochrome P450 monooxygenase and its redox partners. In direct proximity to the genes encoding for the key enzymes of this oxidative demethylation, genes encoding for zinc-dependent alcohol dehydrogenases (ADHs) were identified, which seem to be conserved in porphyran utilizing marine Flavobacteriia. Considering the fact that dehydrogenases could play an auxiliary role in carbohydrate degradation, we aimed to elucidate the physiological role of these marine ADHs. Although our results reveal that the ADHs are not involved in formaldehyde detoxification, a knockout of the ADH gene causes a dramatic growth defect of Zobellia galactanivorans with G6Me as a substrate. This indicates that the ADH is required for G6Me utilization. Complete biochemical characterizations of the ADHs from Formosa agariphila KMM 3901T (FoADH) and Z. galactanivorans DsijT (ZoADH) were performed, and the substrate screening revealed that these enzymes preferentially convert aromatic aldehydes. Additionally, we elucidated the crystal structures of FoADH and ZoADH in complex with NAD+ and showed that the strict substrate specificity of these new auxiliary enzymes is based on a narrow active site.
There is broad scientific consensus that current food systems are neither sustainable nor resilient: many agricultural practices are very resource-intensive and responsible for a large share of global emissions and loss of biodiversity. Consequently, current systems put large pressure on planetary boundaries. According to economic theory, food prices form when there is a balance between supply and demand. Yet, due to the neglect of negative external effects, effective prices are often far from representing the ‘true costs’. Current studies show that especially animal-based foodstuff entails vast external costs that currently stay unaccounted for in market prices. Against this background, we explore how informational campaigning on agricultural externalities can contribute to consumer awareness and tolerance of this matter. Further, we investigate the socially just design of monetary incentives and their implementation potentials and challenges. This study builds on the informational campaign of a German supermarket displaying products with two price tags: one of the current market price and the other displaying the ‘true’ price, which includes several environmental externalities calculated with True Cost Accounting (TCA). Based on interpretations of a consumer survey and a number of expert interviews, in this article we approach the potentials and obstacles of TCA as a communication tool and the challenges of its factual implementation in agri-food networks. Our results show that consumers are generally interested in the topic of true food pricing and would to a certain extent be willing to pay ‘true prices’ of the inquired foods. However, insufficient transparency and unjust distribution of wealth are feared to bring about communication and social justice concerns in the implementation of TCA. When introducing TCA into current discourse, it is therefore important to develop measures that are socially cautious and backed by relevant legal framework conditions. This poses the chance to create a fair playing (‘polluter pays’) with a clear assignment of responsibilities to policy makers, and practitioners in addition to customers.
Einleitung/Hintergrund
DC_TRAIN_APHASIA ist eine multizentrische, randomisiert-kontrollierte Studie, die seit November 2019 unter Federführung der Universitätsmedizin Greifswald durchgeführt wird (ClinicalTrials.gov Identifier: NCT03930121). Die Studie untersucht, ob adjuvante transkranielle Gleichstromstimulation („transcranial direct current stimulation“, tDCS) den Erfolg einer 3‑wöchigen intensiven Sprachtherapie bei chronischer Aphasie steigern kann.
Material und Methode
Bis Ende 2024 sollen bundesweit 130 Patient:innen eingeschlossen werden. Die Entwicklung innovativer Rekrutierungsstrategien stellt seit Beginn der Studie eine Herausforderung dar. Neben gängigen Rekrutierungsmethoden wie der direkten Ansprache von Menschen mit Aphasie in Kliniken, Logopädiepraxen, Rehabilitationseinrichtungen und Selbsthilfegruppen wurden Radiowerbespots, Fernsehbeiträge und Auftritte in sozialen Medien erprobt.
Zwischenergebnisse
Bis zum aktuellen Zeitpunkt konnten 110 Patient:innen in die Studie eingeschlossen werden. Zum größten kurzzeitigen Rücklauf führte die Rekrutierung über einen Fernseh- bzw. Radiobeitrag. Den größten langfristigen Rücklauf ergab die Rekrutierung über Logopädie- und Neurologiepraxen, Selbsthilfegruppen und soziale Medien. Teilnehmer:innen berichteten als „Testimonials“ positiv von der Sprachtherapie und der Anwendung von tDCS, die sich als gut verträglich erwies.
Diskussion
Die multizentrische Studie DC_TRAIN_APHASIA prüft die Wirksamkeit von tDCS als adjuvante Applikation für intensive Sprachtherapie bei chronischer Aphasie. Die vorliegende Übersicht soll künftigen Studien als Leitfaden zur Rekrutierung von Stichproben dienen, die Menschen mit eingeschränkten kommunikativen Fähigkeiten umfassen.
Purpose
Despite being rarely reported, ischemic insults resulting from compromising small brainstem perforators following microvascular decompression (MVD) remain a potential devastating complication. To avoid this complication, we have been using indocyanine green (ICG) angiography intraoperatively to check the flow within the small brainstem perforators. We aim to evaluate the safety and usefulness of ICG videoangiography in MVD.
Methods
We extracted retrospective data of patients who received ICG videoangiography from our prospectively maintained database for microvascular decompression. We noted relevant data including demographics, offending vessels, operative technique, outcome, and complications.
Results
Out of the 438 patients, 15 patients with a mean age (SD) of 53 ± 10.5 years underwent intraoperative ICG angiography. Male:female was 1:1.14. The mean disease duration prior to surgery was 7.7 ± 5.3 years. The mean follow-up (SD) was 50.7 ± 42.0 months. In 14 patients, the offending vessel was an artery, and in one patient, a vein. Intraoperative readjustment of the Teflon pledget or sling was required in 20% (3/15) of the cases. No patient had any sort of brainstem ischemia. Eighty percent of the patients (12/15) experienced complete resolution of the spasms. 86.7% (13/15) of the patients reported a satisfactory outcome with marked improvement of the spasms. Three patients experienced slight hearing affection after surgery, which improved in two patients later. There was no facial or lower cranial nerve affection.
Conclusion
Intraoperative ICG is a safe tool for evaluating the flow within the brain stem perforators and avoiding brainstem ischemia in MVD for hemifacial spasm.
Toarciconiopteryx dipterosimilis gen. et sp. nov. is described from the Lower Toarcian of Grimmen (Western Pomerania, Germany) based on a hind wing. This enigmatic wing superficially resembles a dipteran forewing, but analysis in detail establishes that it belongs to the Neuroptera. We assign it to the Coniopterygidae with great confidence by its great concordance with the hind wings of that family, but a small possibility remains that it might belong to the Dipteromantispidae, although the very derived haltere-like hind wings of all its known members are entirely unlike it. We, therefore, consider it to be the oldest record of Coniopterygidae. We create the new subfamily Toarciconiopteryginae subfam. nov. for it, which is distinguished from other Coniopterygidae by its hind wings possessing two branches of RP and a proximal forking of M. These conditions are also known in some Sialidae (Megaloptera), supporting the hypothesis that Coniopterygidae is the sister group of all other Neuroptera, as Megaloptera is considered by most authors to be sister to Neuroptera. New interpretations of some aspects of the Coniopterygidae venation are proposed.
Flies form high-density associations with human settlements and groups of nonhuman primates and are implicated in transmitting pathogens. We investigate the movement of nonhuman primate-associated flies across landscapes surrounding Kibale National Park, Uganda, using a mark–recapture experiment. Flies were marked in nine nonhuman primate groups at the forest edge (x̄ = 929 flies per group), and we then attempted to recapture them in more anthropized areas (50 m, 200 m and 500 m from where marked; 2–21 days after marking). Flies marked in nonhuman primate groups were recaptured in human areas (19/28,615 recaptured). Metabarcoding of the flies in nonhuman primate groups revealed the DNA of multiple eukaryotic primate parasites. Taken together, these results demonstrate the potential of flies to serve as vectors between nonhuman primates, livestock and humans at this biodiverse interface.
Medieval texts reveal the normalised presence of Saami peoples in medieval Fennoscandia, suggesting close interactions involving trade, relationships, rituals, and magic. Despite growing recognition of these relations, the Saami remain overlooked in general studies of the Middle Ages, often relegated to symbolic roles or footnotes. As a result, Saami characters are typically depicted as the exotic Other within Norse society, often being stripped of agency and humanity in historical narratives. To counter these biases and distorted narratives, an essential step is analysing exclusionary structures in medieval literature and critically reviewing existing research on Saami representation. This process challenges dehumanising portrayals and confronts present-day stereotypes. The present study aims to ‘re-humanize’ (as Paulette F. C. Steeves puts it) the medieval Saami past by using decolonising frameworks and perspectives offered by the so-called ‘Indigenous turn’ of medieval studies, bridging medieval studies and Indigenous studies within a Norse context.
The hypothalamus–pituitary–adrenal axis is the main physiological stress response system and regulating the release of cortisol. The two corticoid receptors encoded by the genes NR3C1 and NR3C2 are the main players in regulating the physiological response to cortisol. This biological system has been linked to neurocognitive processes and memory, yet the mechanisms remain largely unclear. In two independent general population studies (SHIP, total sample size > 5500), we aim to diseantangle the effects of genetic variation, gene expression and cortisol on verbal memory and memory associated brain volume. Especially for NR3C1 results exhibited a consistent pattern of direct an interactive effects. All three biological layers, genetic variation (rs56149945), gene expression for NR3C1 and cortisol levels, were directly associated with verbal memory. Interactions between these components showed significant effects on verbal memory as well as hippocampal volume. For NR3C2 such a complex association pattern could not be observed. Our analyses revealed that different components of the stress response system are acting together on different aspects of cognition. Complex phenotypes, such as cognition and memory function are regulated by a complex interplay between different genetic and epigenetic features. We promote the glucocorticoid receptor NR3C1 as a main target to focus in the context of verbal memory and provided a mechanistic concept of the interaction between various biological layers spanning NR3C1 function and its effects on memory. Especially the NR3C1 transcript seemed to be a key element in this complex system.
The aim of this study was to investigate the impact of resilience, alexithymia and the subjectively perceived severity (fear of death, pain intensity, helplessness) of myocardial infarction (MI) on posttraumatic symptom severity (PTSS) after MI. Patients were assessed with the Posttraumatic Diagnostic Scale (PDS), Resilience Scale (RS-11) and Toronto Alexithymia Scale (TAS-20). Subjectively perceived severity of MI was measured with three items on a 10-point Likert scale. To test our hypothesis, we applied Pearson correlations as well as multiple hierarchical linear regression analyses. A higher resilience score was significantly associated with lower (r = − .39, p < .001) PTSS. Higher scores of alexithymia (r = .38, p < .01) and subjectively perceived helplessness (r = .42, p < .001) were associated with higher PTSS. Multiple hierarchical linear regression analyses revealed that resilience, the TAS-20 subscale difficulty identifying feelings (DIF) and especially subjectively perceived helplessness were independent significant predictors for the PTSS, adjusted R2 = .29, F(5, 102) = 9.57, p < .001. Our results suggest that resilience reduces the PTSS whereas alexithymia and subjectively perceived helplessness increase the risk. Especially the subjectively perceived helplessness explains a high degree of variance of PTSS and should be assessed to hindering further mental health burden.
Purpose
The significance of the underlying literature in clinical guidelines can be weakened by the risk of bias, which could negatively affect the recommendations. Especially in controversial matters, such as fluoride use for caries prevention in children, biased results may be not reliable and lead to incorrect conclusions. This study was performed to detect bias in underlying literature of the German guideline for caries prevention using fluoride in children, where no consensus was reached between paediatricians and paediatric dentists.
Methods
Three tools used for risk of bias assessments of different study designs were RoB 2 for RCTs, ROBINS-I for non-randomized studies, and ROBIS for systematic reviews. For each study cited in the guideline two independent risk of bias assessments were performed. Disagreements were resolved by consensus.
Results
Out of 58 papers, 48.3% (n = 28) showed high risk of bias, with the majority in sections regarding fluoride tablets, fluoridated toothpaste, and paediatricians’ recommendations. 9 out of 20 recommendations and statements were based on studies with high risk of bias, all of which were in these three controversial sections. 13 out of 29 RCTs showed high risk of bias (44.8%), as all 13 non-randomized trials did, while only 2 of 16 (12.5%) systematic reviews had high risk of bias.
Conclusion
Considering risk of bias of cited studies in clinical guidelines may result in substantial changes in its recommendations and aid in reaching consensus. Efforts should be made to assess risk of bias of underlying literature in future clinical guidelines.
The German Centre for Cardiovascular Research (DZHK) is one of the German Centres for Health Research and aims to conduct early and guideline-relevant studies to develop new therapies and diagnostics that impact the lives of people with cardiovascular disease. Therefore, DZHK members designed a collaboratively organised and integrated research platform connecting all sites and partners. The overarching objectives of the research platform are the standardisation of prospective data and biological sample collections among all studies and the development of a sustainable centrally standardised storage in compliance with general legal regulations and the FAIR principles. The main elements of the DZHK infrastructure are web-based and central units for data management, LIMS, IDMS, and transfer office, embedded in a framework consisting of the DZHK Use and Access Policy, and the Ethics and Data Protection Concept. This framework is characterised by a modular design allowing a high standardisation across all studies. For studies that require even tighter criteria additional quality levels are defined. In addition, the Public Open Data strategy is an important focus of DZHK. The DZHK operates as one legal entity holding all rights of data and biological sample usage, according to the DZHK Use and Access Policy. All DZHK studies collect a basic set of data and biosamples, accompanied by specific clinical and imaging data and biobanking. The DZHK infrastructure was constructed by scientists with the focus on the needs of scientists conducting clinical studies. Through this, the DZHK enables the interdisciplinary and multiple use of data and biological samples by scientists inside and outside the DZHK. So far, 27 DZHK studies recruited well over 11,200 participants suffering from major cardiovascular disorders such as myocardial infarction or heart failure. Currently, data and samples of five DZHK studies of the DZHK Heart Bank can be applied for.
Flies are implicated in carrying and mechanically transmitting many primate pathogens. We investigated how fly associations vary across six monkey species (Cercopithecus ascanius, Cercopithecus mitis, Colobus guereza, Lophocebus albigena, Papio anubis, and Piliocolobus tephrosceles) and whether monkey group size impacts fly densities. Fly densities were generally higher inside groups than outside them, and considering data from these primate species together revealed that larger groups harbored more flies. Within species, this pattern was strongest for colobine monkeys, and we speculate this might be due to their smaller home ranges, suggesting that movement patterns may influence fly–primate associations. Fly associations increase with group sizes and may thus represent a cost to sociality.
The extent to which the left–right dimension still structures party systems in highly developed, industrialized democracies is a contested field in comparative politics. Most studies in this area take the position that a stable and universal left–right dimension is either still the most important game in town or has become obsolete and replaced by other policy dimensions. Although country-specific studies focusing on voters’ left–right self-placement discover different meanings of left and right that vary between countries and change over time, few macro-comparative studies focusing on parties or governments take this aspect into account. Using a left–right concept for party politics from the PIP project on Parties, Institutions and Preferences that distinguishes an ideological core derived from political theory, as well as country- and time-specific issues uncovered through empirical analysis, the article demonstrates fundamental differences in the relevance and meaning of left and right by analyzing 34 party systems from 1945 to 2020. The article shows that the thesis of the decline of the left and right is premature. An important aspect for the continued high relevance of the left–right dimension is the fact that left and right changes their meaning by including controversial issues such as European integration, migration and environmental degradation.
Objective
To conduct a systematic review of the published scientific evidence to evaluate the efficacy of nonsurgical periodontal therapy (NSPT) in treating periodontitis in patients with concurrent systemic conditions (diabetes, CVD, erectile dysfunction, chronic kidney disease, rheumatoid arthritis, polycystic ovarian syndrome, obesity, pregnancy). We hypothesised that NSPT results in better periodontal outcomes when compared to untreated controls after follow-up.
Materials and methods
A systematic search (PUBMED/EMBASE) was conducted from 1995 to 2023 to identify randomised controlled trials (RCTs) with a minimum follow-up of 3 months. The primary outcome was the difference in mean probing depth (PD), and the secondary outcomes were mean clinical attachment loss (CAL), percentage of sites with PD ≤ 3 mm (%PD ≤ 3 mm) and percentage of sites with bleeding on probing (%BOP) between the treated and untreated control group in patients with comorbidities.
Results
The electronic search resulted in 2,403 hits. After removing duplicates, 1,565 titles and abstracts were screened according to the eligibility criteria, resulting in 126 articles for full-text screening. Following this, 44 studies were analysed. Restricting to studies with low bias or some concerns, NSPT group demonstrated a 0.55 mm lower mean PD (95%CI: −0.69; −0.41) after 3 months compared to the control group.
Conclusion
Compared to the untreated controls, NSPT notably reduced mean PD, mean CAL, and %BOP while increasing %PD ≤ 3 mm in patients with concurrent systemic conditions. These findings suggest that NSPT is also an effective procedure in managing periodontitis in patients with concurrent systemic conditions.
Trial registration
This systematic review was registered under the protocol registration number CRD42021241517/PROSPERO.
