From the Λ cold dark matter paradigm, it is expected that galaxies merge and grow in their environments. These processes form various tidal features depending on the merger mass ratio, orbital parameters, and gas richness. We inspected 170

-band Abell cluster observations from the 2.1 m Fraunhofer-Teleskop Wendelstein and identify 111 of such features from which we select nine streams and five tails. A fast and innovative technique was developed for determining their photometric properties. The model is a Gaussian, including higher-order moments to describe the light profile in slices perpendicular to the elongation direction. From these models, FWHM apertures are generated. The method was developed, tested, and applied on the selected features and corresponding g- and r-band data from the Legacy Survey DR10. Regarding the novel modeling approach, we can measure surface and total brightnesses with precisions of 4% and 7%, respectively. Mean stream width precision, which also translates to the mean R
e along the feature is on average within 3% uncertainty. The measured streams have on average a surface brightness of

mag arcsec−2 and are dimmer than the tails in our sample (

mag arcsec−2). We infer that the progenitors of our streams can come from dwarfs, early-type galaxies or disks, based on the streams structural parameters. Furthermore, brightnesses and colors of the streams and tails are consistent with those of galaxies that populate the red sequence in the Coma cluster within 2σ.
Understanding Streaming Instabilities in the Limit of High Cosmic-Ray Current Density
Authors: Lichko Emily , Caprioli Damiano , Schroer Benedikt , Gupta Siddhartha
Published: February 2025

A critical component of particle acceleration in astrophysical shocks is the nonresonant (Bell) instability, where the streaming of cosmic rays (CRs) leads to the amplification of magnetic fields necessary to scatter particles. In this work we use kinetic particle-in-cell simulations to investigate the high-CR-current regime, where the typical assumptions underlying the Bell instability break down. Despite being more strongly driven, significantly less magnetic field amplification is observed than in low-current cases, an effect due to the anisotropic heating that occurs in this regime. We also find that electron-scale modes, despite being the fastest growing, mostly lead to moderate electron heating and do not affect the late evolution or saturation of the instability.
The Guitar Filament’s Magnetic Field Revealed by Starlight Polarization
Authors: Dinsmore Jack T. , Romani Roger W. , Mandarakas Nikos , Blinov Dmitry , Liodakis Ioannis
Published: February 2025

The Guitar nebula surrounding PSR B2224+65 boasts a pulsar X-ray filament likely aligned with the local magnetic field. We present new RoboPol stellar polarization data distributed along the line of sight to the pulsar. The polarizing effect of intervening magnetized dust allows us to extract a model for the dust-weighted magnetic field. We detect a magnetic field angle consistent with the filament if the pulsar is located in the more distant zone of its parallax-estimated distance range.

Most stripped-envelope supernova progenitors are thought to be formed through binary interaction, losing hydrogen and/or helium from their outer layers. Ultrastripped supernovae are an emerging class of transient that are expected to be produced through envelope stripping by a neutron star companion. However, relatively few examples are known, and the outcomes of such systems can be diverse and are poorly understood at present. Here we present spectroscopic observations and high-cadence, multiband photometry of SN 2023zaw, a rapidly evolving supernova with a low ejecta mass. SN 2023zaw was discovered in a nearby spiral galaxy at D = 39.7 Mpc. It has significant Milky Way extinction, E(B − V)MW = 0.21, and significant (but uncertain) host extinction. Bayesian evidence comparison reveals that nickel is not the only power source and that an additional energy source is required to explain our observations. Our models suggest that an ejecta mass of M
ej ∼ 0.07 M
⊙ and a synthesised nickel mass of M
Ni ∼ 0.007 M
⊙ are required to explain the observations. We find that additional heating from a central engine, or interaction with circumstellar material, can power the early light curve.
The Influence of Stellar Chromospheres and Coronae on Exoplanet Transmission Spectroscopy
Authors: Perdelwitz Volker , Chaikin-Lifshitz Adam , Ofir Aviv , Aharonson Oded
Published: February 2025

A main source of bias in transmission spectroscopy of exoplanet atmospheres is magnetic activity of the host star in the form of stellar spots, faculae, or flares. However, the fact that main-sequence stars have a chromosphere and a corona and that these optically thin layers are dominated by line emission may alter the global interpretation of the planetary spectrum has largely been neglected. Using a JWST NIRISS/SOSS data set of hot Jupiter HAT-P-18 b, we show that even at near-IR and IR wavelengths, the presence of these layers leads to significant changes in the transmission spectrum of the planetary atmosphere. Accounting for these stellar outer layers thus improves the atmospheric fit of HAT-P-18 b and increases its best-fit atmospheric temperature from

Correcting the Coordinates for Old Novae V707 Sco and V721 Sco
Authors: Schaefer Bradley E.
Published: February 2025

V707 Sco (Nova Sco 1922) and V721 Sco (Nova Sco 1950 no. 3) were both faint, poorly observed, classical novae near the Sting of the Scorpion. Both have substantially incorrect cataloged coordinates. I have recovered the correct coordinates by going back to the original Harvard archival plates. V707 Sco is at J2000 17:48:25.31, −36:36:37.0. V721 Sco is at J2000 17:42:14.62, −34:41:41.0. With these new positions, deep searches should turn up the quiescent counterparts, with their study adding to the large program of measuring the demographics of novae.

Published: February 2025

Introduction: Coronavirus disease 2019 (COVID-19) continues to pose a significant public health threat, requiring epidemiological and genomic surveillance. Next generation sequencing (NGS) is commonly utilized for monitoring viral evolution at a high cost. This study evaluated pooled sequencing as a cost-effective tool for monitoring virus variants.
Methodology: A simulation study was conducted to evaluate the efficacy of sample pooling for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing. In total, 72 original sets of raw data of gene sequencing with different genotypes were collected and combined to create 70 simulated samples based on five pooling strategies. A bioinformatics tool based on Freyja was utilized to analyze the variant composition of these 70 simulated pooled samples. The efficiency of recovering the correct genotypes of the original samples among different pooling strategies, result reports, and genotypes was evaluated with R software.
Results: The genetic composition of the pooled samples mostly recovered the genotype compositions of the original samples, with discrepancies between the top X results (where X is the number of original samples in the pool) and the complete results (p < 0.05). Variability in identification efficiency of genotypes were observed in the reports for the top X results (p < 0.05) across the five pooling strategies, but not in the reports of complete results (p > 0.05). Some original samples of low quality were not accurately identified.
Conclusions: Sample pooling coupled with streamlined genotyping offers a promising approach for cost-effective gene sequencing of SARS-CoV-2, which will aid in COVID-19genomic surveillance.

Published: February 2025

A Rapid Assessment Protocol (RAP) for non-canopy spiders was used to collect replicate samples from four lowland rainforest sites for a proof-of-concept comparison of spider assemblages from the Democratic Republic of the Congo (hereafter, Congo) and Panama. Collecting was done at two 0.25 ha sites in Panama and two 0.25 ha sites in Congo. At each site, three 0.01 ha plots were randomly located, and within each we did 1 person-hour of aerial sampling (sweeping and beating/brushing) and two person-hours of ground sampling (field sieving of leaf litter). The samples yielded 350 adult spiders belonging to 29 spider families. The Panama samples yielded more adult spiders (235 vs. 115) and more spider families (24 vs. 14) than the Congo samples. Overall, the dominant five spider families in these non-canopy samples were Theridiidae (24%), Salticidae (15%), Linyphiidae (11%), Oonopidae (10%), and Pholcidae (7%), with the 20 remaining families each making up less than 5% of the total adults. The three most abundant families in Congo were Theridiidae, Oonopidae, and Thomisidae, while the top three in Panama were Salticidae, Theridiidae, and Linyphiidae. An NMDS ordination analysis of the four plots failed to show significant differences between any of the four assemblages, but when the plots were analyzed by region, there was a significant difference in the family-level assemblages between the continents. This paper shows proof-of-concept that this RAP can produce statistically valid data from brief sampling trips by teams with inexperienced collectors and simple, inexpensive sampling equipment.

Published: February 2025

Turf-grasses are economically important horticultural crops, which have been utilised by humans to improve the environment for more than a thousand years. Turf-grasses are widely distributed in landscapes, slopes and sport fields, such as golf courses. Endophytic fungi are a resource of unexplored fungal diversity with potential bioactive compounds. In this study, culture-independent ITS amplicon sequencing and culture-dependent isolation methods were used to reveal fungal community in roots of the turf-grass Zoysia japonica. A total of 317 OTUs were identified from root samples of Z. japonica by analysis of ITS amplicon reads. Fungal community was dominated by Sordariales (32.45%), followed by Chaetothyriales (18.16%), unknown taxa in Sordariomycetes (14.63%) and Pleosporales (12.48%). During isolation, 151 endophytic fungal strains were obtained from roots of Z. japonica and a variety of taxa were found by ITS amplification and sequencing. Moreover, 11 endophytic fungal species were further characterised in this study, based on morphological characterisation and multi-loci phylogenetic analysis, including Niesslia dimorphospora, a newly-recorded species in Korea and 10 novel species (Dactylaria hwasunensissp. nov., Lophiostoma jeollanense sp. nov., Magnaporthiopsis zoysiaesp. nov., Poaceascoma endophyticumsp. nov., P. koreanumsp. nov., P. magnumsp. nov., P. zoysiiradicicolasp. nov., Stagonospora endophytica sp. nov., Setophoma zoysiaesp. nov. and Pseudorhypophila poaesp. nov.). Antifungal activities of these species were tested against the turf-grass brown patch pathogen Rhizoctonia solani AG2-2(IIIB), with S. zoysiae being the best antagonist. In addition, butanol extract from mycelia of S. zoysiae strongly inhibited R. solani AG2-2(IIIB) in vitro and in planta. The results of this study expand the biodiversity of endophytic fungi and revealed potential biological resources for future turf-grass management and bioactive compound exploitation.
Prevalence of Vision and Eye Movement Abnormalities in Children Referred to the Children's Epilepsy Surgery Service: A 5-Year Observational Study
Authors: Chan Shu-Yi Claire , Warnes Penny , Warsame Maryama , Atan Denize
Published: February 2025

Purpose

To report the prevalence of visual acuity, visual field, and ocular motility problems in children with epilepsy referred to the Children's Epilepsy Surgery Service (CESS) for surgery.

Methods

This was a retrospective observational study of all children referred to the CESS in Bristol between 2015 and 2020. Data extraction included age, age at epilepsy diagnosis, epilepsy etiology (as determined by seizure semiology, neuroimaging, and electroencephalography), anti-seizure drugs, visual acuity, visual field, ocular motility, and fundus imaging.

Results

A total of 221 children with epilepsy were seen during the study period: 60% (132/221) had structural etiologies, 8% (18/221) were genetic, and in 28% (62/221) the etiology was unknown. Overall, 53% (117/221) were found to have abnormalities, particularly strabismus (16%, 36/221), visual field defects (14%, 27/198), and reduced visual acuity (12%, 26/219). Notably, 54% (63/117) of children with ophthalmic abnormalities were new diagnoses in the CESS clinic. Younger children and those with neurodevelopmental disorders were less likely to complete all vision tests.

Conclusions

Ophthalmic abnormalities were prevalent among children referred for epilepsy surgery in Bristol and more than half were previously undiagnosed. The data support the adoption of an orthopticled vision screening service for children with medically refractory epilepsy, structural etiologies, and focal seizures, to better support their needs in the community.

Authors: Ganesh Sandra C. , Lusobya Rebecca Claire , Jogitha  , Rao Shilpa G. , Uduman Muhammed Sithiq , Devi Renuka , Narendran Kalpana
Published: February 2025

Purpose

To evaluate the efficacy of a single dose of botulinum toxin A injection into the medial rectus muscle to treat acute acquired concomitant esotropia (AACE).

Methods

This observational case series study included patients diagnosed as having AACE from January 2021 to December 2023 at a tertiary eye care center in South India willing to undergo botulinum toxin injections as the first treatment who experienced sudden-onset esotropia with diplopia. Their demographics, duration of symptoms, and visual acuity were recorded. Orthoptic evaluations, including measurement of esodeviation (prism cover test) for distance and near fixation, assessment of binocularity (Worth 4-dot test), anterior and posterior segment evaluations, and cycloplegic refraction, were conducted for all cases. Neurological examinations and relevant imaging studies were performed. All participants received a predetermined botulinum toxin A dose injected into the medial rectus muscle. Evaluations were conducted at 1 week, 1, 3, and 6 months, and 1 year after injection. Main outcome measures were ocular deviation and restoration of binocularity after botulinum toxin A injection. Motor success after injection was defined as angle of deviation less than 8 prism diopters of esotropia and sensory success as absence of diplopia.

Results

A total of 72 patients were included in the study. Their mean age was 10.39 ± 5.73 years (range: 2 to 24 years) and 49 (68.1%) were male and 23 (31.9%) were female. Forty-nine (63.88%) had emmetropia, 7 (9.7%) had myopia, and 19 (26.38%) had hyperopia. After injection, the percentage of patients experiencing diplopia reduced from 79.2% at presentation (n = 57) to 18.6% at 1 week after injection (n = 13), 4.9% at 1 month after injection (n = 3), 2.2% at 3 months after injection (n = 1), and none at 6 months and 1 year after injection. Forty-two (58.3%) patients for distance and 41 (56.9%) for near attained motor and sensory success as early as 1 week after injection. Of the 28 patients who attended follow-up visits more than 1 year after injection, 85.7% maintained both motor and sensory success.

Conclusions

Botulinum toxin A is an effective first-line treatment for patients with AACE. It provides sustainable motor and sensory restoration, faster rehabilitation, and reduced need for invasive surgery in at least two-thirds of patients.

Claude Autant-Lara, Jacques Prévert et l’adaptation au cinéma de l’opérette Ciboulette (1932-1933)
Authors: Janssens Christian
Published: February 2025

Le premier long métrage français de Claude Autant-Lara, co-scénarisé par celui-ci avec Jacques Prévert, a été relativement peu étudié jusqu’à présent. Son intérêt réside dans la situation paradoxale des deux auteurs : au début des années 1930, agents de la sphère de qualité, non reconnus par leurs pairs, ils acceptent un travail de commande destiné au grand public, à savoir l’adaptation de l’opérette « à succès » Ciboulette. À l’appui principal d’archives « non-film » – deux scénarios conservés dans le fonds Claude Autant-Lara de la Cinémathèque Suisse, le troisième par la fondation Fatras/Succession Jacques Prévert –, nous montrons qu’en fonction d’exigences contradictoires, les deux auteurs choisissent et modifient leur stratégie d’adaptation.
Simonne Mareuil, « étoile d’aujourd’hui » sans lendemain
Authors: Albera François
Published: February 2025

La jeune femme du Chien andalou a connu un destin singulier : débutant sans « métier » dans de nombreux films dès 1922, elle connaît un moment de célébrité en 1926 où l’on voit en elle une « étoile d’aujourd’hui », une « jeune première de comédie ». Les revues publient son portrait en « une » et les lecteurs peuvent commander sa photo dédicacée. Puis, après Peau de Pêche, Un chien andalou et Ces dames aux chapeaux verts, sa carrière s’infléchit, malgré le soutien de Marie Epstein et Jean Benoit-Lévy. Jusqu’en 1939 elle est cantonnée à des rôles secondaires et on l’oublie. Son spectaculaire suicide par le feu en 1954 rappelle qu’elle fut la partenaire de « l’épileptique » Pierre Batcheff dans le film de Buñuel et Dalí, le seul que l’on cite désormais. C’est cependant l’image qu’elle donnait alors dans ses autres films qui peut faire comprendre le choix des cinéastes du Chien andalou.
A Knowledge-Driven Approach to AI-Based Personalized Test Paper Creation in Programming Education
Authors: Wu Zhiqiang , Wan Shuhui
Published: February 2025

Computer programming education plays an important role in modern society, however, students' knowledge base, learning style, and ability level vary widely. Personalized teaching has become a key issue in education reform. As the existing question bank system mainly labels the difficulty coefficient of the questions by manual means, and cannot objectively and accurately provide personalized learning paths for different students. This paper puts forward two parameters of “students' ability value” and “difficulty value of test question”, constructs the corresponding relationship table between students' ability value and difficulty value of test question, establishes the mathematical model, and generates the test paper that meets students' learning ability. Compared with other algorithms, the algorithm designed in this paper has a faster convergence speed and the success rate of paper generation. Through practical application and questionnaires, it is evident that the personalized question bank designed in this paper can effectively help students better grasp programming knowledge.

Several authors have developed equations to estimate methane (CH4) emissions by cattle according to variables such as dry matter and nutrient intake, live weight, or weight gain. Mathematical models using these variables show a large variability of results, being necessary to identify those which provide more precise and accurate predictions. For this reason, the objective of this study was to validate enteric CH4 emissions estimated from mathematical models through a comparison with a database of CH4 emissions obtained from cattle experiments carried out in tropical regions. A database of 495 individual cattle CH4 emissions data (g day-1) obtained from 19 studies in three tropical Latin American countries was built for this study. Results showed that mathematical models developed for cattle in tropical production systems overestimated CH4 emissions when they were compared with our database. The mathematical model with higher precision and accuracy was the one that included dry matter intake and organic matter digestibility in the equation (Equation 7. R2=0.34, Cb=0.94, CCC=0.55, RMSE=60.8%, r=0.58), followed by models that included neutral detergent fiber intake data (Equation 5). Our data did not show a relationship between CH4 emissions and gross energy intake or live weight.

Wistar rats were treated as Group A: Control; Group B: Lead (50 mg kg-1 b wt.); Group C: Lead (50 mg kg-1 b wt.) and jamun seed extract (JSE) (200 mg kg-1 b wt.); Group D: Lead (50 mg kg-1 b wt.) and orange peel extract (OPE) (200 mg kg-1 b wt.); Group E: OPE (200 mg kg-1 b wt.) and Group F: JSE (200 mg kg-1 b wt.). Serum urea, creatinine and serum uric acid levels were analyzed on days 7 and 14. Rats from Group B showed increased serum creatinine from days 7 to 14. Creatinine level decreased in group C and group D at days 7 and 14 as compared to group B. Increased serum urea was recorded in group B rats from 7 days. Rat from group C or group D showed decreased serum urea after days 7 day and 14 as compared to Group B. Lead exposure to rats provoked increased serum uric acid on days 7 and 14. Uric acid decreased in group C and group D on days 7 and 14 as compared to rats of group B. No alteration in creatinine, urea and uric acid level was seen in OPE and JSE treated rats at days 7 and 14.

Published: February 2025

In view of the need to improve the development of family production enterprises, zootechnical and economic planning were conducted in a rural settlement in 0.78 ha of water depth for the rearing and marketing of juveniles of the tambatinga hybrid (♀ tambaqui Colossoma macropomum x ♂ pirapitinga Piaractus brachypomus) to verify its economic viability. For the zootechnical indicators, a 16-month production cycle was determined, with three juvenile production cycles and two fattening cycles. For the remaining fish that were not sold, the quantity of initial and final fish, stock biomass, average initial and final weight, apparent feed conversion, and mortality rate were determined. For economic planning, a total operating cost methodology was adopted to determine the costs per unit of production, gross revenue, gross margin, net profit, and profitability index. The production of juveniles of many sizes is economically viable for family farming, showing attractive profitability indicators even under adverse zootechnical conditions. This study demonstrated the effectiveness of zootechnical and economic planning on a property that can optimize production and use of the area, as well as showing producers how rewarding it is to farm fish.

Published: February 2025

This study aimed to evaluate the effectiveness of different LED lamp colors (red and white) on the productive performance and egg quality of light laying hens. A total of 144 birds of the commercial strain Hy-Line® W-36 aged 44 weeks were distributed in a completely randomized design with two treatments (red and white LEDs) and 12 replicates, totaling 24 experimental plots with six birds each. Treatment means were compared by the F Test (5% probability) on the statistical software SISVAR. This study found that laying hens under red LED lamps showed a trend of greater egg production bird-1 day-1 (%) (p = 0.084), average egg weight (g) (p = 0.0826), egg mass (p < 0.05), and shell thickness (mm) and height (mm) (p < 0.01), whereas birds under white LED light showed better yolk color (p < 0.05). It is concluded that red LED illumination increases egg production and quality in light laying hens.

Return to work after breast cancer: barriers and facilitators
Authors: Ruggieri Raffaella , Gabanelli Paola , Belluccio Chiara , Giorgi Ines , Fiabane Elena
Published: February 2025

Breast cancer is the most diagnosed neoplasm among women. The incremental advantages obtained in terms of survival make it possible to consider this disease as a chronic disease. Furthermore, the increasing impact on working-age women associated with the increase in the retirement age raises the question of return to work (RTW). Adequate work reintegration is important from a psychological, economic and social point of view. The objective of this study is to investigate the factors implicated in the RTW of women diagnosed with breast cancer according to recent scientific literature. The factors involved in returning to work after breast cancer are classifiable in socio-demographic, medical-clinical, occupational, psychosocial, cognitive and physical activityrelated factors. Among these the most cited are the medicalclinical (treatments, type of cancer, disease-related consequences), work-related (support from colleagues and supervisors, characteristics of work and the workplace) and psychosocial (social support, depression, anxiety) factors. The results obtained allow to have some indications for planning return to work interventions after breast cancer. Future studies are needed to distinguish the implication of factors at each stage of the RTW process in order to plan successful RTW interventions.
A FOLLOW-UP STUDY ON THE REDUCTION OF BURNOUT LEVELS THROUGH MINDFULNESS MEDITATION IN HEALTH CARE PROFESSIONALS

Published: February 2025

The 8-week mindfulness meditation (MM) trainings have proven to be helpful for reducing burnout due to work-related stress. Most studies reported these positive effects with evaluations made immediately before and immediately after the therapeutic interventions. Little is known, however, about the symptoms of burnout in the months following these interventions.In our exploratory study, the effects of an 8-week MM training were assessed in a group of health care professionals (n = 19) with vulnerability to develop burnout; a 9-month follow-up was conducted on the subjects (n=8) who continued to meditate after the end of the training. Other health care professionals of the same company, who did not meditate during this research, served as control group. Burnout, mindfulness abilities and job satisfaction were evaluated through self-reports.Data showed that during the training the levels of burnout did not decrease, but significant reductions were observed during the follow-up. This indicates the possibility of obtaining results with MM even in subjects who do not have standard response time to the therapy and highlights the importance of monitoring the healing process.

The ageing of the population has confronted manycountries with the problem of the progressive decline in thepercentage of people participating in the labour force. It is estimated that in 2050, people over 60 will make up 37% of the entire European population and 22% of the world's population. Lengthening working careers and increasing labour participation have consequently become important strategic objectives in some Nordic countries as well as in many other western countries.
EXPOSURE RISK FOR WORKERS IN AN HADRONTHERAPY CENTRE AND COLLECTIVE AND INDIVIDUAL PROTECTION MEASURES
Authors: Ferrarini Michele
Published: February 2025

In the last few years a wide dissemination of hadrontherapy facilities is taking place. In these facilities, proton or heavy ion (mainly carbon) accelerators are used to treat cancers in peculiar positions (i.e. close to critical organs), 58 or with peculiar biological features that make them not eligible for conventional radiation therapy with photons.During the design, the commissioning and the use of these facilities many radiation safety issues are to be addressed, that are different from the ones that the professionals in the field are used to facing.Many problems need to be solved, among which the characterization of the radiations fields produced by the accelerators, the shielding design, the design of the interlock systems, and the management of the activated materials (PE1I). Both the personal and environmental dosimetry systems need to be set up and implemented, taking into consideration the peculiarities of the involved radiation fields, that are often made of many different high energy particles.So, the approach to this kind of problems is usually much more complex than the one that is required for lower energy machines, and the adopted techniques are much more similar to the ones used for the high energy research accelerators.Due to the complexity of the physics involved in the radiation/ matter interaction at these energies, the radiation safety calculations are often based on Monte Carlo simulations (that take into account all the physical processes for all the particles involved), and the data should be cross-checked with the experimental data available in literature (e.g. Na06).Moreover, all the radiation measurements must be carried out with instruments conceived for this kind of radiation fields, or anyway with instruments whose behavior can be foreseen also when measuring in high energy mixed fields (Na04).The shielding design and the activation evaluations obviously depend on the different accelerator technologies (e.g. if synchrotrons, or cyclotrons, are used) and on the energy and nature of the accelerated beam. On the other hand, while the technologies used for the interlock safety systems are well known, a big research and development effort is still ongoing about the technologies adopted for personal or environmental dosimetry. Anyway, while the state-of-the-art of instrumentation is still far from being completely satisfactory, many detectors are available, that can be a good option to solve some of the measurement problems found in such environments.
[The protections of workers with oncological pathologies and the role of the competent doctor for their reintegration into work]
Authors: Caldi Fabrizio , Guglielmi Giovanni , Cristaudo Alfonso
Published: February 2025

The protection of the worker affected by neoplastic pathologies and his reintegration into work represent subjects of undoubted relevance for the occupational physician. Many are the workers affected by neoplastic diseases and more are those who are able to regain good living conditions and sufficient work capacity to be reintegrated into profitable work. Several rights are related to the assessment of a certain percentage of disability, the recognition of "Handicap in a serious situation", and others according to the requirements of the Italian law for the right to work of disabled people (L. 68/99 s.m.i.).The Occupational Physician manages the oncology patient through the targeted placement ex L. 68/99 s.m.i. or, more often, during the activity of health surveillance has to assess whether the job, considering the risks connected to it, is compatible with the conditions of biological validity of the worker, identifying, possibly, prescriptions or limitations.In our experience, customized working plan is an operational methodology that has proved to be very useful.In practice, the Occupational Physician uses a method to help the back to work of the worker with disability, formalizing before the limits to the performance of the work activity.The assessment of fitness for work is related to a work plan presented by the employer, based on the indications of the occupational physician, based on disability (health conditions/worker's susceptibility) that modulates or avoids job tasks that could prove harmful or aggravating the health condition of the employee. Teleworking and smart working can also be considered among the possible protection measures.Finally, it is useful to recall the role of INAIL for workers with a recognized neoplastic pathology related to work.With the Italian law 190/2014 art. 1, paragraph 166 are assigned to the INAIL the skills relating to the reintegration and work integration of people with disabilities from work with expenses for the INAIL. There are therefore a number of reference measures by the ¡INAIL and the types of interventions for reintegration are identified.

Objective. To describe the functional recovery of consecutive inpatients with Critical Illness Polyneuropathy (CIP) at the time-point of the discharge from rehabilitation units according to Barthel Index scores. To examine whether age, gender, pre-ICU admission diagnosis, tracheostomy performance, heterotopic ossification development and duration of neuro-rehabilitation treatment are among the prognostic factors that can predict the functional outcome in studied patients.Design. A retrospective observational clinical study from January 2010 to December 2014. Three rehabilitation units in Greece.Results. Sixteen subjects (57.1%) had >60 Bl discharge scores, showing a prospect in gaining further independence. Females presented a tendency for better functional outcome vs males (73.8±12.6 vs 58.6±23.4, p=0.082). Respiratory, septic and neurologic patients demonstrated better rates of functional improvement after the rehabilitation process vs cardiac patients (p<0.001, p=0.009 and p=0.019, respectively vs p=0,072). Heterotopic ossification development proved to be an adverse independent prognostic factor of functional outcome (47.8 ≤ 25.7 vs 68.8 ≤ 17.7, p=0.023).Conclusions. A proportion of included patients experienced severe disability with poor prospect of further functional development and return to work at the discharge from the rehabilitation units. According to the present study, which is the first that focuses only on CIP and its outcome, specific prognostic factors can be defined. Our results can be used as pilot data for larger studies, so that firmer conclusions can be drawn.
[The Digital Fitness in the Neuromotor Field]
Authors: Springhetti Isabella
Published: February 2025

The digitization of processes has become a necessity to make health management remain sustainable.Current organizational models do not enable the increasing efficiency in process governance required by the increasing demand for rehabilitation services. Vice versa, new technologies have an innovative potential for compensation of disability and for operations management. This is context in which the concept of a "comprehensive digital rehabilitation" also said "digital gym" is developed: as a governance system for the whole inpatient rehabilitation path. The author describes the fundamentals of the Maugeri clinical model for a "Digital Gym" and examines some methodological, clinical and organizational issue concerning: information technology, machine operation protocols, clinical evaluation, machine operator interaction, patient doctor interaction, personalization of care, operational changes linked to the electronic workschedule, and the important training needs.

Published: February 2025

Seaports are complex systems in which workers can be exposed to a large variety of safety and health risks. Nevertheless, a little literature is available concerning this topic, if we exclude the specific area of shipbuilding industry.Objectives. The aim of this paper is to update the review of the scientific literature previously published as result of a project concerning the occupational risks in seaports.Methods. Literature on this theme, obtained consulting the main databases (PubMed, Scholar and CCOHS) from 2012 and up to April 2019, was reviewed.Results. Five of eight articles published after 2012 were related to risk of release or formation of volatile compounds in restricted and poorly ventilated areas or inhalation of particles from specific goods. Three papers specifically debated musculoskeletal disorders related to loading unloading procedures, occupational diseases and injuries.Conclusions. The update of the literature highlighted intrinsically dangerous goods, toxic volatile compounds and emissions as critical aspects of seaport activities related to goods handling. Recently, the literature shows a growing interest in occupational health, especially work-related musculoskeletal diseases. Prevention measures and implementation of worker's training and information are identified by all authors as the more effective action to increase health and safety.
[Bio-hazard in research laboratories]

Published: February 2025

Objectives. To deal with biohazards in research laboratories (RL), identify exposure features, types and incidence of laboratory-acquired infections/diseases (LAI), and prevention strategies.Methods. Literature search and appraisal, non-systematic, last 40 years; legislation, guidelines and good practices evaluation. Results. Biohazards are relevant in RL, in various biomedical, agri-food and industrials sectors, with a variety of LAI (especially viruses and bacteria), modes of exposure and transmission; LAI decrease after preventive measures, vaccinations and clinical treatments; LAl underestimation, due to underreporting and subclinical LAI; need to implement and comply with well-known and available technical and scientific guidelines, good medical and laboratory practices; need for specific health education and training; lack of reporting and epidemiologic surveillance systems, with consequent limited data on risk assessment and effectiveness of preventive interventions. Conclusions. The roles of the occupational physician must be underlined, especially for risk assessment, health and clinicepidemiologic surveillance, with the need to monitor effectiveness of preventive interventions, particularly for biosafety and biosecurity levels in RL. It should be useful to increase capacity of epidemiologic surveillance for LAI, through networking or dedicated websites, in order to collect and analyze accidents, injuries, infections, or adverse events occurred to workers in RL.

Authors: Jain Prachi , Rathee Manu , Bansal Arush , Jain Shreya
Published: February 2025

Background:

Oral health plays a crucial role in maintaining the general health of an individual. Parkinson disease (PD) has known to disrupt the oral functions. Prosthetic rehabilitation can be done in these patients. However, there is scarcity of literature to assess the effectiveness or impact of rehabilitation with prosthesis either fixed or removable on various oral functions and quality of life (QoL) or satisfaction of PD patients. The purpose of this systematic study was to assess the effectiveness of prosthodontic rehabilitation in patients with PD.

Materials and Methods:

The literature search was conducted in the PubMed and CINAHL database for the articles till 2024 in English language. An exploration of gray literature was also included through Google Scholar. Manual search in the references of the selected articles was also done for relevant articles. The methodological quality assessment of cohort studies was done using Newcastle–Ottawa quality assessment form for Cohort Studies (NOS). Assessment of cross-sectional studies was done using the Appraisal tool for Cross-Sectional Studies (tool) and aassessment of case series was done using JBI critical appraisal tool for case series.

Results:

A total of 6 articles were selected from PubMed, 1 from CINAHL, and 2 from Google Scholar. Four articles studied the masticatory efficiency. Oral perception and motor ability were analyzed in two articles. Oral Health QoL was assessed in four articles. One article studied the electromyographic activity.

Conclusion:

Based on this systematic review, it can be suggested that prosthetic rehabilitation using fixed or removable prosthesis offer potential benefits in PD patients improving the oral functions and QoL. However, there is a dearth of long-term research on evaluation of impact of prosthetic rehabilitation in improving the oral function and QoL of PD patients.
