Published: December 2024

Aims. Pulsating stars in eclipsing binary systems offer a unique possibility to empirically identify pulsation modes using the geometric effect of the eclipses on the pulsation signals. Here we explore the δ Scuti-type pulsations in the eclipsing binary system KIC 3858884 with the aim of identifying the dominant modes using various photometric methods.
Methods. We used the Kepler short-cadence photometry data. Refined binary model and pulsation parameters were determined using an iterative separation of the eclipsing binary and pulsation signals. We used the photometric residuals, a phase modulation study, and a double eclipse mapping (EM) to identify the host stars of the dominant pulsations. Échelle diagram diagnostics were employed to locate the frequencies most affected by the eclipses. Direct-fitting (DF) methods assuming spherical harmonic surface patterns were explored to determine an orientation for the symmetry axis and to infer surface mode numbers ℓ and m. Ancillary mode number estimates were obtained from reconstructions of general surface patterns using dynamic eclipse mapping (DEM). The use of these methods allowed mode identifications that are independent of asteroseismic models.
Results. We unambiguously established the secondary star as the main source of the pulsations. Seven peaks were found to show pronounced modulations during the secondary eclipses. For the first time, we were able to detect two hidden modes with amplitude intensification during the eclipses. Only one additional frequency appears to originate from the primary. DF results point to an essentially aligned pulsation axis for the secondary. We successfully reconstructed surface patterns and determined mode numbers for most of the selected frequencies with both of our methods. We found one radial and three sectoral modes, (1,−1), (2,±2), and (3,±3). The two strongest modes were both found to be nonradial. The hidden modes were identified as (3,±1) and (2,±1), respectively. We find one additional radial mode to be a combination frequency. The partial disagreement between the results of the two methods may indicate that either the strongest modes deviate from strict spherical harmonics, or that the pulsation axis cannot be constrained by the photometric data alone. Future spectroscopic observations could help in resolving this discrepancy.

Published: December 2024

Introduction: Meniscal injuries often occur in association with anterior cruciate ligament (ACL) injury. Failure to detect meniscal tears in patients with ACL injuries can lead to more complex tears and make them more difficult to repair. Objective: To determine the degree of correlation between magnetic resonance imaging (MRI) and knee arthroscopy in diagnosing meniscal injuries in patients with ACL tears. Methods: A prospective descriptive study was conducted on 185 patients diagnosed with ACL tears through knee arthroscopy at Thong Nhat Hospital from April 2023 to April 2024. Results: The accuracy of MRI and its correlation with arthroscopy in detecting meniscal injuries is 69.2%, indicating a low degree of agreement between MRI and arthroscopy results. Diagnosis of meniscal injury location has an accuracy of 57.1%, indicating a minimal to low degree of agreement between MRI and arthroscopy results. Diagnosis of the injury region: Accuracy over 85%, with Kappa coefficients ranging from 0.3 to 0.59, p < 0.001. Diagnosis of the morphology of meniscal injuries: Accuracy over 89%, with Kappa coefficients ranging from 0.26 to 0.66, p < 0.001. Conclusion: There is a minimal to moderate correlation between MRI and arthroscopy in detecting, and diagnosing the location, region, and morphology of meniscal injuries in patients with ACL tears. Therefore, caution is advised when diagnosing meniscal injuries based solely on MRI findings in patients with ACL tears.
Functional outcomes of three-corner fusion without triquetrum excision versus conventional four-corner fusion in scaphoid non-union advanced collapse G II and III in active patients: a prospective randomized control trial
Authors: Youssef Khaled Nabil , Nabil Amr , Atiya Ahmed Naeem , El-Mahy Mohammed Mostafa 
Published: December 2024

Introduction: Four-corner fusion has long been the preferred treatment for stages II and III of scaphoid nonunion advanced collapse with intact radiolunate articulation. Three corner fusions were then proposed as a more limited procedure with improved ulnar deviation through triquetrum excision. However, we believe triquetrum preservation would decrease the radiolunate contact pressure without affecting the ulnar deviation range. Methods: This prospective randomized study was performed between March 2019 and May 2021 and involved a total of 34 patients who underwent four corner fusions or three corner fusions without triquetrum excision for SNAC grade II and III. The average follow-up period was 2 years. Follow-up included radiological and clinical evaluation (range of motion, grip strength, visual analogue scale, and modified Mayo wrist scores). Results: There were no significant differences between the two groups as regards the postoperative range of motion, grip strength, visual analogue scale, modified Mayo wrist scorers, and complication rate. However, the three-corner fusion group had less mean operative time compared to the four-corner fusion (mean ± SD; 77.6 ± 16.9, 103.8 ± 10.2 min – P < 0.001) respectively. Conclusion: The authors concluded that three-corner fusion without triquetrum excision offered a comparable functional outcome and complication rate to four-corner fusion with less operative time in the three-corner fusion group.

Authors: Cejka Daniel 
Published: December 2024

ZUSAMMENFASSUNGEin neuer Ansatz zur Beurteilung des CKD-MBD-Syndroms (CKD-MBD: „chronic kidney disease – mineral bone disorder“) ist die Messung des Mineral-Puffer-Systems des Blutes. Mittels der Messung von endogenen Kalziproteinpartikeln (CPP: „calciprotein particles“) und der Bestimmung der CPP-Kristallisations-Zeit ex vivo (T50-Test) kann der Gesamtzustand des Mineral-Puffer-Systems des Blutes festgestellt werden. In Zukunft könnte die Optimierung des Mineral-Puffer-Systems die bisherigen Parameter – Phosphat, Kalzium, Parathormon (PTH) – ersetzen. Entsprechende klinische Studien sind allerdings noch erforderlich.

Authors: Marin Cuartas Tomas , Nasri Ahmad Farid , Bollmann Stefan 
Published: December 2024

Zusammenfassung
Anamnese und klinischer Befund Eine 59-jährige Patientin mit unauffälliger Krankengeschichte stellte sich wegen seit ca. 7 Tagen bestehender wässriger Diarrhöen, starken Unterbauchschmerzen und Fieber vor. Bei der körperlichen Untersuchung war das Abdomen distendiert, die Darmgeräusche waren nicht auskultierbar, und es bestand ein akutes Abdomen mit generalisierter Abwehrspannung sowie deutlich erhöhten Entzündungsparametern.
Untersuchungen Die Computertomografie des Abdomens zeigte einen ausgeprägten Aszites und Zeichen einer Peritonitis. Es bestand die Indikation zur operativen Exploration. Zunächst erfolgte eine Laparoskopie. Hierbei zeigte sich eine diffuse eitrige Peritonitis. Eine Organperforation oder ein anderweitiger Focus konnten ausgeschlossen werden.
Diagnose, Therapie und Verlauf Nach Abstrich-Entnahme erfolgte die ausgiebige Lavage und Drainagen-Einlage. Die bakteriologische Untersuchung und die Blutkulturen zeigten β-hämolysierende Streptokokken der Gruppe A, was zur Diagnose einer spontanen bakteriellen Streptokokken-Peritonitis führte. Die Patientin wurde antibiotisch behandelt, erholte sich zunehmend und konnte beschwerdefrei entlassen werden.
Folgerung Die primäre spontane bakterielle Peritonitis durch Streptococcus pyogenes gehört zu den seltenen Ursache eines akuten Abdomens. Eine frühzeitige Diagnose und sofortige Antibiotikatherapie sind entscheidend für die Prognose.
Berufsbezogener Ü45-Gesundheitscheck: Liegt ein Bedarf bei
Beschäftigten in der Pflege vor?
Authors: Raiber Lea , Kaluscha Rainer , Tepohl Lena 
Published: December 2024

Zusammenfassung
Ziel der Studie Die hohen physischen und psychischen Belastungen im
Pflegeberuf können sich negativ auf den Gesundheitszustand der Pflegekräfte
auswirken. Das Modellprojekt „Gesundheitscheck für Pflegekräfte aus dem Stadt-
und Landkreis Karlsruhe“ bot Pflegenden ab dem 45. Lebensjahren – auf Basis
ihrer selbsteingeschätzten Arbeitsfähigkeit mittels Work Ability Index (WAI) –
die Teilnahme an einem berufsbezogenen Gesundheitscheck an. Diese Arbeit
betrachtet die berufliche und gesundheitliche Situation von älteren
Pflegekräften, den (subjektiven) Bedarf für einen Ü45-Gesundheitscheck und zieht
einen Vergleich zwischen Teilnehmer/-innen und Nichtteilnehmer/-innen.
Methodik 1.466 Pflegekräfte im Alter zwischen 45 und 52 Jahre wurden zur
Teilnahme am Ü45-Gesundheitscheck eingeladen und im Nachgang schriftlich
befragt. Die Datengrundlage bildeten 202 Fragebögen (49 Teilnehmer/-innen und
153 Nichtteilnehmer/-innen). Es erfolgte eine deskriptive Auswertung und mittels
Chi2- und Rangsummentests wurden Gruppenunterschiede analysiert.
Ergebnisse Als Hauptbelastungsfaktoren der befragten Pflegekräfte wurden
organisatorische Umstände, hohe Arbeitsintensität sowie unzureichende Entlohnung
identifiziert. Erkrankungen bzw. Beschwerden des Muskel-Skelett-Systems und der
Psyche waren am stärksten verbreitet. 18,6% der Befragten waren eher bzw. sehr
unzufrieden mit ihrem gegenwärtigen Gesundheitszustand. Als stark bzw. sehr
stark gefährdet durch die aktuelle Tätigkeit sahen 39,1% ihre körperliche und
27,6% ihre seelische Gesundheit. 25,9% der Pflegekräfte hielten es für sehr
unwahrscheinlich und 32,4% für eher unwahrscheinlich, dass sie bis zum Erreichen
des Rentenalters in der Pflege tätig sein können. Einen persönlichen Bedarf für
einen Ü45-Gesundheitscheck sahen 63,0%. Gruppenunterschiede zwischen
Teilnehmer/-innen und Nichtteilnehmer/-innen zeigten sich durch eine signifikant
höhere Belastung aufgrund von Muskel-Skelett-Erkrankungen (p=0,0002),
Gesundheitszufriedenheit (p=0,0053), den subjektiven Bedarf für einen
Gesundheitscheck (p<0,0001) und Belastungsfaktoren am Arbeitsplatz
(körperliche Tätigkeiten [p=0,00035], zeitgleiche Bewältigung vieler Aufgaben
[p=0,0380], Umgang mit kognitiv eingeschränkten [p=0,0095] sowie mit
leidenden/sterbenden Patienten/-innen [p=0,0164]).
Schlussfolgerung Die Pflegekräfte berichteten von einem hohen
Belastungsniveau am Arbeitsplatz und häufig von gesundheitlichen
Beeinträchtigungen. Es wird deutlich, dass ein konkreter Bedarf zur
Inanspruchnahme eines berufsbezogenen Ü45-Gesundheitschecks für diese Alters-
und Berufsgruppe besteht.

Published: December 2024

ZusammenfassungDer Einsatz von Psychedelika in Psychiatrie und Psychotherapie wird vertieft
wissenschaftlich untersucht, national wie international zunehmend fachlich und
gesellschaftlich diskutiert sowie international bereits teilweise klinisch
praktiziert. Der Artikel bietet eine kurze Standortbestimmung auch hinsichtlich
Evidenzlage, kritischer klinischer Fragen und Risiken. Rechtliche, ethische und
ökonomische Aspekte werden beleuchtet, therapeutische Qualifikationen möglicher
Anwender werden diskutiert und es wird unter Benennung noch aktueller
Herausforderungen auf eine mögliche klinisch-psychiatrische Einbettung
eingegangen. Insgesamt wird besprochen, unter welchen Voraussetzungen in der
Anwendung von Psychedelika ein gewisses Potenzial hinsichtlich Erweiterung des
Behandlungsspektrums psychischer Erkrankungen liegen könnte, insb. angesichts
auch unter derzeitigen Methoden häufig therapieresistenter und chronischer
Verläufe. Auf jeden Fall wären wesentliche grundsätzliche Fragen vor einer
eventuellen Einführung zu klären.
Association Between Homocysteine and All-Cause Mortality Among
Osteoarthritis Patients: A Cohort Study from the NHANES Database
Authors: Shi Yu , Lu Minan , He Feng , Chen Jinzhong , Zheng Chuanchuan , Lu Lu 
Published: December 2024

AbstractThis study explored the association between serum Hcy level and the all-cause
mortality among osteoarthritis (OA) patients. This cohort study included
patients diagnosed as OA from the National Health and Nutrition Examination
Survey (NHANES) 1999–2006. Abbott Homocysteine assay, a fully automated
fluorescence polarization immunoassay (FPIA) method, was used to measure the
level of serum Hcy. Covariates included sociodemographic information,
lifestyles, history of diseases and medications were extracted from the
database. The weighted univariate, multivariate Cox proportional hazard models
and restricted cubic splines (RCS) were utilized to explore the association
between Hcy level and all-cause mortality in OA patients, with hazard ratios
(HRs) and 95% confidence intervals (CIs). Subgroup analyses based on different
age, gender, duration of OA, complications and C-reactive protein (CRP) were
further assessed by this association. Totally 1384 OA patients were included in
this study, of which 817 (59.03%) died by 31 December 2019. After adjusting all
covariates, high Hcy level was associated with the high all-cause mortality
among OA patients (HR=1.31, 95%CI: 1.02–1.67), especially in females (HR=1.43,
95%CI: 1.07–1.91), aged >60 years (HR=1.49, 95%CI: 1.14–1.94), duration of OA
>10 years (HR=1.40, 95%CI: 1.01–1.95), with the history of hypertension
(HR=1.37, 95%CI: 1.03–1.80), without the history of diabetes (HR=1.36, 95%CI:
1.01–1.82) or CRP >0.29 mg/l (HR=1.51, 95%CI: 1.04–2.19). High serum Hcy
level was associated with high risk of all-cause mortality in OA patients. Our
results suggest that serum Hcy is a promising biomarker for the prognosis of OA
patients.

Published: December 2024

Abstract
Introduction Duodenal atresia is one of significant causes of neonatal intestinal obstruction. It often co-occurs with Down syndrome. This study is conducted to estimate the global prevalence of duodenal atresia in Down syndrome patients and to investigate associated factors.
Methods Conducting a systematic review with meta-analysis of 18 eligible studies reporting duodenal atresia prevalence in pediatric Down syndrome patients. Study quality is assessed using the Newcastle-Ottawa Scale. The subgroup analysis on region, study quality, publication year, and design is addressed. Gender-specific prevalence rates are examined.
Results The pooled prevalence of duodenal atresia in Down syndrome is 3.0%, with significant heterogeneity. The Middle East reports a higher prevalence of 6.0%, while Latin America, India, and Canada exhibit a lower prevalence of 1.0%. High-quality studies demonstrate 2% prevalence, while moderate-quality studies report 4.0%. Gender analysis indicates a similar incidence for females and males at 3.0%. Prevalence varies with study design: case-control studies report 4.0%, cross-sectional studies report 2.0%, and prospective cohort studies report 2.0%.
Conclusions Duodenal atresia is common in Down syndrome patients, affecting 3.0% of the patients worldwide. Regional variations exist, necessitating further investigation. Gender does not significantly impact prevalence. This study highlights the need for region-specific research to enhance clinical decision-making for individuals with Down syndrome and duodenal atresia.

Authors: Kumar Niraj , Pal Chandan Kumar , Betgeri Somsharan Shankerappa , Mukund Amar 
Published: December 2024

Abstract
Introduction Femoral pseudoaneurysm is one of the common complications following femoral artery catheterization. It poses a significant morbidity and a nonsurgical technique with the utmost low complication risk is warranted. Various methods have been used to treat these pseudoaneurysms including manual compression, ultrasound-guided compression, and percutaneous injection of thrombin or glue. Various novel methods are also being used to treat the pseudoaneurysms, including angioseal closure device, vascular plugs, etc. Cirrhosis poses a separate challenge with deranged coagulation and hyperfibrinolysis, making traditional methods, which are dependent on patients' coagulation cascade, less effective.
Materials and Methods We used a novel technique to treat the complicated femoral pseudoaneurysm using a suture-mediated closure device, Perclose ProGlide system (Abbott Vascular, California, United States). The transaneurysmal approach was used in seven patients. All the patients had acute or chronic liver disease with deranged coagulation. Six patients had femoral arterial access for angiographic procedure while one had a femoral line for intensive care unit monitoring. Compression was done in all the patients, but failed. Percutaneous injection of thrombin was done in two patients.
Results Technical success was achieved in 7/7 (100%) patients. There was instantaneous thrombosis of the pseudoaneurysm, which was confirmed the next day by ultrasound. There were no procedure-related complications.
Conclusion Transaneurysmal closure of the femoral pseudoaneurysm using suture-mediated closure device is a novel and effective, minimally invasive bedside technique that can be used in patients with deranged coagulation.

Authors: Nischal Neha , Mishra Chetna , Singh Jatinder Pal 
Published: December 2024

AbstractShoulder pain is a common and increasing indication for patients being referred for pain relief injections. To address this, patients are offered corticosteroid injections for the glenohumeral joint as well as the subacromial subdeltoid (SASD) bursa under ultrasound guidance, which allows direct visualization of the needle and target structures with a more confident and real-time needle placement. We demonstrate a new technique, the rotator interval bursa (RIB) technique, of sequential injection of the glenohumeral joint targeting the rotator interval as well as the SASD bursa via the anterior approach with a single prick.

Published: December 2024

After the successful synthesis of graphene, the search area for 2D-nanomaterials became even larger. Currently, studies have been expanded from graphene to transition metal dichalcogenides such as molybdenum disulfide (MoS2), molybdenum diselenide (MoSe2), tungsten disulfide (WS2), and layered transition metal oxides. In this study, MoS2-nanoflakes were prepared by the liquid phase exfoliation technique. Binary mixtures of ethanol and deionized water in different percentages (100%, 80%, 60%, 40%, 20%, and 0%) were used as the solvent to synthesize the MoS2-nanoflakes in a large scale. The quality of the solvents for exfoliation was determined using the Hansen solubility parameters. The analysis revealed that 60% ethanol-to-water mixture worked better than all the other mixtures. This study explored the structural, morphological, and optical properties of the produced nanoflakes. The UV–Vis spectroscopy showed a rise in absorption intensity with increasing sonication time, indicating thickness reduction of the nanoflakes. In addition, the yield percentage increases up to 20% with increasing sonication time. From the atomic force microscope images, the average thickness of the MoS2-nanoflakes has been found to be ∼10 nm. However, it has been found that the thickness of the nanoflakes decreases with increasing sonication time. Fourier transform infrared spectroscopy has confirmed that there was no contamination. The lateral size of the nanoflakes has been determined using dynamic light scattering. For 60% ethanol solvent, the lateral size of the nanoflakes has been found to be 168.6 nm. The dispersion remained stable for ∼28 days.
