The speed and phase of locomotion dictate saccade probability and simultaneous low-frequency power spectra
Authors: Barnes Lydia , Davidson Matthew J. , Alais David 
Published: July 2024

Abstract
Every day we make thousands of saccades and take thousands of steps as we explore our environment. Despite their common co-occurrence in a typical active state, we know little about the coordination between eye movements, walking behaviour and related changes in cortical activity. Technical limitations have been a major impediment, which we overcome here by leveraging the advantages of an immersive wireless virtual reality (VR) environment with three-dimensional (3D) position tracking, together with simultaneous recording of eye movements and mobile electroencephalography (EEG). Using this approach with participants engaged in unencumbered walking along a clear, level path, we find that the likelihood of eye movements at both slow and natural walking speeds entrains to the rhythm of footfall, peaking after the heel-strike of each step. Compared to previous research, this entrainment was captured in a task that did not require visually guided stepping – suggesting a persistent interaction between locomotor and visuomotor functions. Simultaneous EEG recordings reveal a concomitant modulation entrained to heel-strike, with increases and decreases in oscillatory power for a broad range of frequencies. The peak of these effects occurred in the theta and alpha range for slow and natural walking speeds, respectively. Together, our data show that the phase of the step-cycle influences other behaviours such as eye movements, and produces related modulations of simultaneous EEG following the same rhythmic pattern. These results reveal gait as an important factor to be considered when interpreting saccadic and time–frequency EEG data in active observers, and demonstrate that saccadic entrainment to gait may persist throughout everyday activities.

Published: July 2024

Abstract
Evaluating the accuracy and calibration of the redshift posteriors produced by photometric redshift (photo-z) estimators is vital for enabling precision cosmology and extragalactic astrophysics with modern wide-field photometric surveys. Evaluating photo-z posteriors on a per-galaxy basis is difficult, however, as real galaxies have a true redshift but not a true redshift posterior. We introduce PZFlow, a Python package for the probabilistic forward modeling of galaxy catalogs with normalizing flows. For catalogs simulated with PZFlow, there is a natural notion of “true” redshift posteriors that can be used for photo-z validation. We use PZFlow to simulate a photometric galaxy catalog where each galaxy has a redshift, noisy photometry, shape information, and a true redshift posterior. We also demonstrate the use of an ensemble of normalizing flows for photo-z estimation. We discuss how PZFlow will be used to validate the photo-z estimation pipeline of the Dark Energy Science Collaboration, and the wider applicability of PZFlow for statistical modeling of any tabular data.

Abstract
Highly r-process-enhanced (RPE) stars are rare and usually metal poor ([Fe/H] < −1.0), and they mainly populate the Milky Way halo and dwarf galaxies. This study presents the discovery of a relatively bright (V = 12.72), highly RPE (r-II) star ([Eu/Fe] = +1.32, [Ba/Eu] = −0.95), LAMOST J020623.21+494127.9. This star was selected from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope medium-resolution (R ∼ 7500) spectroscopic survey; follow-up high-resolution (R ∼ 25,000) observations were conducted with the High Optical Resolution Spectrograph installed on the Gran Telescopio Canarias. The stellar parameters (T

= 1.52, [Fe/H] = −0.54, ξ = 1.80 km s−1) have been inferred taking into account nonlocal thermodynamic equilibrium effects. The abundances of [Ce/Fe], [Pr/Fe], and [Nd/Fe] are +0.19, +0.65, and +0.64, respectively, relatively low compared to the Solar r-process pattern normalized to Eu. This star has a high metallicity ([Fe/H] = −0.54) compared to most other highly RPE stars and has the highest measured abundance ratio of Eu to H ([Eu/H] = +0.78). It is classified as a thin-disk star based on its kinematics and does not appear to belong to any known stream or dwarf galaxy.
Cosmology from One Galaxy in a Void?
Authors: Wang 汪 Bonny Y. 玥 , Pisani Alice 
Published: July 2024

Abstract
Understanding galaxy properties may be the key to unlocking some of the most intriguing mysteries of modern cosmology. Recent work relied on machine learning to extract cosmological constraints on Ωm using only one galaxy. But if this is true, how should we select the galaxy to use for cosmology inference? In this Letter, we consider selecting a galaxy that lies in cosmic voids, the underdense regions of the cosmic web, and compare the constraints obtained with the ones obtained when randomly selecting a galaxy in the whole sample. We use the IllustrisTNG galaxy catalog from the Cosmology and Astrophysics with MachinE Learning Simulations (CAMELS) project and the VIDE void finder to identify galaxies inside voids. We show that void galaxies provide stronger constraints on Ωm compared to randomly selected galaxies. This result suggests that the distinctive characteristics of void galaxies may provide a cleaner and more effective environment for extracting cosmological information.
Functional knee and ankle outcomes of a peroneus longus tendon autograft for primary reconstruction of the anterior cruciate ligament
Authors: Hassan Alaa Zenhom Mahmoud , Zein Assem M.N. 
Published: July 2024

BackgroundPeroneus longus tendon (PLT) autograft is commonly used for anterior cruciate ligament (ACL) reconstruction because it is easily harvested and has the same size and strength as the ACL. There are few studies in the literature that discussed donor site complications after ACL reconstruction by PLT. PLT was used as an autograft for reconstructions of the medial patellofemoral ligament and deltoid ligament. We evaluated clinical and functional outcomes for knee, foot, and ankle joints after the use of PLT as an autograft in primary isolated ACL reconstruction.Patients and methodsWe retrospectively reviewed all patients who were operated for primary ACL reconstruction by PLT autograft from May 2020 to May 2021. Preoperatively and postoperatively, all patients were examined clinically for knee stability by anterior drawer, Lachman, and pivot shift tests, applying the International Knee Documentation Committee as well as the Lysholm score. American Orthopedic Foot and Ankle Score, Foot and Ankle Ability Measure, and ankle range of motion were used for the evaluation of postoperative foot and ankle functions. Return time to the sport was also evaluated.ResultsSixty-five patients with ACL-injured knees were included. Their mean age was 29.81 ± 8.33 years and ranged from 20 to 45 years, and males were 54 (83%) and females were 11 (17%). The mean postoperative follow-up period was 32.5 ± 3.1 months. Mean of American Orthopedic Foot and Ankle Score was 99.33 and Foot and Ankle Ability Measure was 99.7 after 12 months. Postoperative Lysholm score mean±SD was 95.30 ± 4.65, and the International Knee Documentation Committee mean±SD was 93.47 ± 9.82 withPvalue less than 0.001. Return to sport ranged from 4 to 8 months with mean±SD of 5.67 ± 0.75.ConclusionPLT autograft for primary reconstruction of isolated ACL injury did not affect foot and ankle functions with good knee stability and restoration of knee functions postoperatively, which facilitated the return to preoperative sports activity level.

Published: July 2024

Background
Antimicrobial resistance in surgical infections is known to have significant morbidity and mortality in extreme cases on top of increased costs in medical expenditure. This study aimed to analyze antimicrobial resistance patterns of microbes in open tibia fracture-related infection (FRI) using intraoperative tissue samples.

Methods
Between January and June 2022, a descriptive cross-sectional observational study was conducted involving patients aged 18 and above with open tibial shaft fractures. Microbiological culture and sensitivity of three intraoperative deep tissue and bone samples taken by sterile techniques using separate instruments in patients with infection. Antimicrobial susceptibility testing was performed using the Kirby-Bauer disk diffusion method along with biomechanical tests for microbial identification.

Results
Fifty-seven deep tissue samples were taken from 19 patients with FRI who underwent surgery during the study period were analyzed. Almost all (96.5%) intraoperative tissue samples were culture-positive identifying 73 bacterial isolates out of which 57.9% were polymicrobial. The most frequent isolated bacteria were Gram-negative bacteria 56 (76.7%) with a predominance of Proteus spp 13 (17.8%). Methicilin Resistance Staphyaureus comprised 12 (16.4%) of the isolates whereas Inducible Clindamycin resistance was identified in 8 (57.1%) of Staphyloccus aureus isolates. More than half of the isolates 30 (53.6%) comprised of Extended Spectrum Beta Lactamase producing bacteria. There was high resistance to Cephalosporins and Amoxyclavulanic acid as the efficacy was low ranging from 28.2, 27.8, and 30.0% for cefotaxime, ceftazidime and amoxicillin/clavulanic acid, respectively. Almost all Gram-negative bacteria 47 (83.9%) had multidrug resistance pattern except for Pseudomonas aureginosa that had 77.8 to 88.9% susceptibility to all tested antibiotics.

Conclusion
High resistance to cephalosporins in patients with delayed or late infection in open tibia FRI is alarming and further studies to establish causes are indicated.

Authors: Goudarzi Fatemeh , Babazadeh Raheleh , Ebadi Abbas , Khadivzadeh Talat 
Published: July 2024

Abstract

Background:
Adaptation to complications of hysterectomy is one of the topics of concern for women and health care providers. There is no instrument for evaluating adaptation to hysterectomy. This study aimed to design the Hysterectomy Adaptation Scale (HAS) and assess its psychometric properties.

Materials and Methods:
This methodological study was conducted from 2018 to 2020 in Mashhad, Iran. To develop the item pool, qualitative data from directed content analysis and data from the review of adaptation and coping instruments were used. The face, content, construct validity, internal consistency, and stability were used to evaluate the psychometric properties of HAS.

Results:
The final version of the HAS consisted of 24 items with a reported content validity index of 0.9. Six factors were extracted from the principal component analysis, which explained 60.3 of the observed variance. Model fit indices in confirmatory factor analysis showed that the model was well fitted. The values of the alpha coefficient and intra-class coefficient were 0.86 and 0.95, respectively.

Conclusions:
The HAS is a valid and reliable scale for evaluating the adaptation level of hysterectomized Iranian women. HAS can distinguish between hysterectomized women who have adapted to hysterectomy and those who have not. It can be used to assess the adaptation of hysterectomized women in research and clinical practice.

Authors: Ibrahim Asmaa Abobakr , Gaballah Samia , Abu Bakr Elsaid Noha M. , Mohamed Heba Alkotb 
Published: July 2024

Abstract

Background:
Hypertensive disturbances during pregnancy are the leading cause of maternal and fetal death; unfortunately, no effective treatment exists. Therefore, interventions that reduce the likelihood of developing preeclampsia during pregnancy are required. This study aimed to see how Progressive Muscle Relaxation (PMR) compared to breathing exercise techniques affected Blood Pressure (BP) levels among mildly preeclamptic pregnant women.

Materials and Methods:
A convenience sample was used in a quasi-experimental study of 75 mild preeclamptic pregnant women in the Obstetrical Outpatient Clinics at the Suez Canal University Hospital in Ismailia, Egypt. They were divided into three groups: study group [I]: the deep breathing exercise group; study group [II]: the PMR group; and study group [III]: the control group. Data were collected using two methods: an interviewing information collection tool and a physiological measurement tool.

Results:
There was a statistical significant difference in systolic and diastolic blood pressure after six weeks of training among intervention groups (PMR and breathing excercise technique with p value 0.001 for both groups) compered to contol group. However, there was no statistical difference in BP (systolic or diastolic) after two weeks of intervention among the three groups.

Conclusions:
PMR and breathing techniques could effectively control BP in pregnancy complicated by mild preeclampsia. Both techniques could be introduced in routine antenatal care for women diagnosed with mild preeclampsia. Health and fitness professionals should focus more on preparing and delivering various sports programs incorporating various muscle relaxations and breathing techniques.
The Use of Gemcitabine and Docetaxel as a Novel Combination for Hyperthermic Intraperitoneal Chemotherapy in the Management of Recurrent Complicated Abdominal Sarcoma: Case Report and Review of Literature
Authors: Azzam Ayman Zaki , Aldawalibi Burhan Ammar , Amin Tarek Mahmoud 
Published: July 2024

Abstract
Sarcoma is a rare mesenchymal tumor. Evaluation of sarcoma patients primarily or after recurrence must be done in an experienced center. En bloc surgical resection is the mainstay of treatment for all sarcoma subtypes. The primary surgery or re-resection after recurrence must be done by an experienced, well-trained surgeon. Correlation between the imaging findings, the operative, and the histopathological findings is a must. We report a patient who was diagnosed with retroperitoneal sarcoma and had three surgical resections with incomplete removal. The last resection was complicated by a urinary leak. The tumor was resected piecemeal with the use of gemcitabine and docetaxel as a novel combination for hyperthermic intraperitoneal chemotherapy in recurrent complicated abdominal sarcomas.

ABSTRACT.
Extended spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae poses a global problem and complicates therapeutic choices. The paucity of data in resource-poor countries undermines the understanding of the problem’s extent, and cases of antimicrobial treatment failure continue to accumulate. This study aimed to determine the prevalence and clinical implications of ESBL-producers at the University Teaching Hospital of Kigali in Rwanda. A 1-year cross-sectional retrospective study was conducted on Escherichia coli and Klebsiella pneumoniae isolated in blood and urine from January 1 to December 31, 2022. In total, 1,283 isolates were recorded. The results showed an overall prevalence of ESBL phenotypes at 300/1,283 (23.4%). Extended spectrum beta-lactamase–positive E. coli was more frequently detected than K. pneumoniae in both urine (20.6% versus 10.1%) and blood (8.8% versus 6.2%). These isolates were 100% resistant to amoxicillin-clavulanic acid, third-generation cephalosporins, piperacillin, sulbactam ampicillin, ampicillin, cefuroxime, and cefoxitin. The least resistance was observed to amikacin (18%), meropenem (10%), and polymyxin B (3%). Hospital stays ranging from 8 to 21 days were the most frequent, and the mortality rate was 10.3% in patients with ESBL cases, which was more than double the general hospital mortality rate in the same period. In conclusion, our findings indicate a high prevalence of ESBL phenotypes, high antibiotic resistance rates, prolonged hospital stays, and an increased mortality rate. These findings suggest the need for continued surveillance, planning appropriate interventions, and caution during empirical therapy.
