Published: March 2024

L’intervention relationnelle est particulièrement adaptée pour répondre aux cas de négligence car elle repose sur les réactions de l’enfant comme guide pour ajuster les comportements parentaux. Grâce au visionnement commenté de courts échanges filmés entre l’enfant et son parent, ce dernier peut, avec l’aide de l’intervenant, apprendre à repérer le caractère plus ou moins sensible de ses agissements (ou absence d’agissements) à travers les réponses de l’enfant. Pour rendre le parent réceptif aux observations de l’intervenant, celui-ci veille à identifier et souligner les comportements positifs et adaptés qu’il présente, renforçant ainsi leur fréquence d’apparition et lui permettant de développer un plus grand sentiment de compétence et une meilleure compréhension des besoins de son enfant. Cet article vise à présenter le programme d’intervention relationnelle, sa structure et ses cibles. Cette présentation est illustrée par une vignette clinique. Ce programme a été évalué dans le cadre d’une recherche-action, fondée sur un essai randomisé contrôlé, menée en France auprès de familles suivies par les services de protection de l’enfance. De telles pratiques professionnelles révèlent une amélioration significative des comportements des parents et des enfants par rapport à l’intervention habituelle.

Authors: Derbissaly Bauyrzhan , Sadybekov Makhmud
Published: March 2024

In this paper, we consider an inverse source problem with nonlocal boundary conditions for the heat equation involving multi-term time-fractional derivatives. We determine a source term independent of the space variable, and the temperature distribution from the energy measurement. We reduce the solution of the inverse problem to finding solutions to two problems. The well-posedness of each problem is shown using the generalized Fourier method.
Réorientation à l’université : quand le sens des études se déconstruit et se reconstruit – Vers un processus de « dé-re-Construction » du sens
Authors: Arnoux-Nicolas Caroline , Cocandeau-Bellanger Laurence , Cocandeau Charline , Egido Angel
Published: March 2024

La recherche vise à examiner les processus de déconstruction et de reconstruction de sens dans les études menant à la décision de réorientation intra-universitaire volontaire d’étudiant·es. Le corpus a été recueilli par entretiens semi-directifs auprès de dix étudiant·es français·es. Les données font l’objet d’une double analyse, thématique et manuelle ainsi que lexicale et automatisée (logiciel Alceste). Les résultats soulignent le rôle du sens des études dans la décision de réorientation et proposent une mise en lumière novatrice d’un processus nommé dé-re-construction de sens qui combine la déconstruction du sens et sa reconstruction, deux processus imbriqués, voire concomitants. Les émotions, le ressenti d’incertitude, le mal-être psychologique ainsi que les difficultés et désillusions dans la formation suivie contribuent à la déconstruction de sens tandis que la rencontre avec un autrui significatif, la connaissance de soi et la recherche d’épanouissement favorisent la construction de sens et d’un nouvel équilibre auquel la réorientation peut contribuer.

Authors: Tacchini Sabrina , Brazier Caroline Éliane , Rossier Jérôme
Published: March 2024

De nombreuses activités professionnelles ont des effets dramatiques sur les écosystèmes et contribuent au dépassement des limites planétaires. En parallèle, le modèle économique actuel repose sur l’idée d’une croissance quantitative perpétuelle, qui augmente continuellement les dégradations environnementales. L’AIOSP exhorte la psychologie de l’orientation scolaire et professionnelle à tenir compte des problématiques écologiques et sociales. Le champ pourrait devenir un acteur de la transformation des modes de vie vers davantage de durabilité en proposant des interventions et des perspectives théoriques suggérant que l’activité humaine se situe entre un plafond écologique et un plancher social selon la « théorie du Donut » proposée par Raworth. Cet article propose d’examiner quelques pistes d’interventions compatibles avec cette théorie qui prendraient appui sur le développement de récits, de questionnements et de parcours vocationnels alternatifs. Il présente à titre d’exemple un dispositif groupal d’orientation « Slow ta carrière ! » qui tient compte des limites planétaires.
The critical role of accurate fossil identification: the case of the ostracods of the Codó Formation, NE Brazil
Authors: Coimbra João Carlos , Petró Sandro Monticelli
Published: March 2024

The Class Ostracoda comprises bivalve microcrustaceans with great diversity and abundance in the Lower Cretaceous paleolakes of Brazil and the world. With species generally well-preserved and of relatively short biochrons, it has provided high-resolution biostratigraphic frameworks that permit long-distance correlations. In this context, the Lower Cretaceous biozones of the NE Brazilian basins have allowed the establishment of correlations between coeval geological sections not only in this region but also with those of the Brazilian marginal basins, including the rocks of the pre-salt deposits, as well as with West African basins. In addition to biostratigraphy, these microfossils have proved indispensable in paleoenvironmental and paleogeographical analyses, including studies on the opening of the South Atlantic Ocean. However, some publications have emerged that, regrettably, exhibit errors in species identification and/or the accurate interpretation of biostratigraphic works. These mistakes have led to proposed modifications in both the biochron and geographic distribution of index taxa and taxonomic synonymizations that are incongruent with the current state of knowledge of the species. Consequently, these inaccuracies have given rise to erroneous biochronostratigraphic correlations and paleoenvironmental inferences. In this context, we meticulously examine the current understanding of the taxonomy of ostracods from the Codó Formation (NE Brazil), which is essential for the debate on the use of Lower Cretaceous ostracods in stratigraphy. Keywords: biostratigraphy, paleoecology, microfossils, Lower Cretaceous, Brazil.
Taphofacies of coastal lakes based on mollusk death assemblages: a case study of Mirim Lake
Authors: Schmidt-Neto Hugo
Published: March 2024

Mirim Lake is the second-largest lacustrine body in Brazil, stretching for some 185 km and covering about 375 thousand hectares of water surface. This lake is part of the Patos-Mirim System, one of the world’s largest complexes of coastal lagoons, which is the result of the rise and fall of sea level over transgressive-regressive cycles triggered by glacio-eustasy during the Late Pleistocene and Holocene. Its characteristics and dynamics give it singular importance for studies on the genesis of shell accumulation in lagoons. This study aims to improve the knowledge of how the taphonomic signatures reflect the environmental characteristics and dynamics of Mirim Lake. Categorization of the arrangement and packing of death assemblages, as well as the orientation of shells, supported the biostratinomical approach. The taphonomic signatures included disarticulation, fragmentation, and corrosion of shells. Corrosion is the primary damage observed in the bioclasts, varying from a single loss of color to complete degradation. Differences in the characteristics of death assemblages observed in the dune fields and the lacustrine plain led to the recognition of two taphofacies. A more significant number of whole shells was observed in the dune field taphofacies, while sharp fragments and open-articulated bivalves in hydrodynamic unstable positions characterize the lacustrine plain taphofacies. The genesis of death assemblages and the taphonomic signatures of bioclasts were linked to three sedimentary dynamics attributed to the environment of Mirim Lake. Keywords: biostratinomy, taphonomic signatures, shell deposits, dune field, lacustrine plain.
Taphonomic significance of Aristotle's 'Wheel Paradox': an example with the cerithid gastropod Cerithium atratum (Born, 1778) from Conceição Lagoon, Santa Catarina State, Southern Brazil
Authors: Lopes Renato Pereira , Ferigolo Jorge
Published: March 2024

In the book Mechanical Problems, attributed to Aristotle, the author relates the differential degrees of wearing and rounding of pebbles and shells moved by waves on the seashore to the variable radii and diameters of these particles. This phenomenon, which became known as Aristotle’s ‘Wheel Paradox,’ seems to explain the pattern of abrasion observed in shells of gastropods Cerithium atratum (Born) found in Conceição Lagoon, on the Island of Santa Catarina, Brazil. In situ observations show that the elongated turriform shells of C. atratum deposited at shallow (< 30 cm) depths on a sandy bottom with pavements of disarticulated valves of Anomalocardia flexuosa Gmelin are subject to bidirectional wave-generated currents under fairweather conditions. The 47 specimens analyzed exhibit a pattern of abrasion characterized by the loss of the shell wall, apparently proceeding from the wider last whorl toward the narrow apex, culminating in the exposure of the columella. Experiments designed to test whether this pattern could be related to the ‘Wheel Paradox’ principle show that under bidirectional flow, the shells describe circles on the vertical plane around the longitudinal axis (rolling) and a pendulum movement (revolution) on the horizontal plane centered on the apex. The whorls located farther from the apex have larger diameters and describe broader arc segments. Thus, they have higher tangential velocities and travel longer paths, which could explain why they are abraded earlier than the narrower whorls. Recognizing similar abrasion features in fossil shells can provide information on the local paleo-currents, hydrodynamics, and relative time-averaging of death assemblages and allow distinguishing between natural or anthropogenic modification in archaeological specimens. Although the effects vary between shells with different shapes, Aristotle’s ‘Wheel Paradox’ principle explains the general abrasion pattern among gastropods under certain hydrodynamic conditions.

Relationship between maternal arterial and foetal cord carbon dioxide tension and neonatal outcome in critically ill pregnant women at delivery
Authors: Scharf Katelyn T , Bharadwaj Shobana , Lankford Allison , Wong Michael , Kodali Bhavani S
Published: March 2024

Background and Aims:

No studies have evaluated the relationship between maternal arterial partial pressure of carbon dioxide (mPaCO2) and umbilical cord venous partial pressure of carbon dioxide (PCO2) in critically ill pregnant women at delivery. Based on the studies in healthy pregnant women, an mPaCO2 target of ≤50 mmHg is a suggested threshold during mechanical ventilation in critically ill parturients. We evaluated the relationship between mPaCO2 and neonatal cord gases in critically ill parturients at delivery as the primary objective. The relationship between mPaCO2 and APGAR scores at delivery was also analysed as a secondary objective.

Methods:

Maternal and neonatal cord gas data at delivery and APGAR scores were obtained by a retrospective chart review of 25 consecutive parturients with severe respiratory compromise who were delivered during mechanical ventilation. Linear regression was used to assess the relationship between mPaCO2 and umbilical artery and vein PCO2 and between mPaCO2 and APGAR scores at 1 and 5 min.

Results:

There was a positive correlation between mPaCO2 and neonatal cord venous PCO2 (P = 0.013). Foetal venous PCO2 exceeded predelivery mPaCO2 by 17.5 (7.5) mmHg. There was an inverse relationship between mPaCO2 and neonatal APGAR scores at 1 and 5 min (P = 0.006 and P = 0.007, respectively).

Conclusion:

Foetal cord venous PCO2 can be predicted if mPaCO2 values are known. Unlike in healthy pregnant women, there was an inverse relationship between rising mPaCO2 levels and neonatal APGAR scores in critically ill pregnant women who had several associated compounding factors.
Cost analysis of different medical oxygen sources for a healthcare facility in India
Authors: Manhas Varun , Rawat Mahipal , Kaurav Yogesh S. , Goyal Sanjay , Dhir Sanjay , Sangineni Kalyani
Published: March 2024

Background and Aims:

Multiple sources of medical oxygen, namely liquid medical oxygen (LMO) tanks, pressure swing adsorption (PSA) plants, concentrators, and gaseous cylinders, are available at different healthcare facilities. These sources of oxygen have varying installation and operational costs. In low-resource settings, it is imperative to utilise these assets optimally. This study investigated the operational costs of multiple oxygen sources available at a healthcare facility.

Methods:

A Microsoft (MS) Excel-based model was developed to analyse and compare the oxygen manufacturing costs (in ₹/m3) using PSA plants and procurement costs (in ₹/m3) of LMO and third-party vendor-refilled cylinders.

Results:

The oxygen manufacturing costs for PSA plants of different capacities and running times on electricity and diesel generators (DGs) as a power source were calculated. This study highlights the cost-benefit of using PSA plants over LMO and third-party vendor-refilled cylinders as a source of oxygen. PSA plants are most economical when they are of higher capacity and used to their maximum capacity on electricity as the power source. On the contrary, they are most expensive when used on a DG set as a power source. Furthermore, this study provides evidence of PSA plants being more cost-effective for refilling cylinders using a booster compressor unit when compared to third-party vendor-cylinder refilling.

Conclusion:

Given their cost-effectiveness and low third-party dependence, they should be utilised to their maximum capacity as medical oxygen sources at healthcare facilities.
Prevalence and predictors of preoperative cardiac autonomic dysfunction among elective neurosurgical patients: A prospective observational study
Authors: Sangeetha RP , Chakrabarti Dhritiman , Sriganesh Kamath , Mahendranath Musumur , TN Sathyaprabha , Srinivas Dwarakanath
Published: March 2024

Background and Aims:

The autonomic nervous system (ANS) is cardinal for systemic homeostasis. Autonomic dysfunction is prevalent in as high as 65% of patients presenting for cardiac surgery in the Indian scenario. Pre-existing cardiac autonomic dysfunction (CAD) in surgical patients can accentuate perioperative haemodynamic fluctuations during stressful intraoperative events, predispose to adverse cardiac events, and contribute to morbidity and mortality. The prevalence and predictors of CAD in the elective neurosurgical population are unknown in the Indian scenario. The current study was conducted to bridge this knowledge gap.

Methods:

In this single-centre prospective observational study conducted at a tertiary care neurosciences centre, among 400 consenting adult patients of either gender, between 18 and 80 years of age, undergoing elective neurosurgery, the preoperative ANS function at the bedside was assessed as the primary outcome measure. The ANS status was evaluated using ANSiscope™-derived indices of heart rate variability. The diagnosis of CAD was made when the ANS index exceeded a threshold of 13.5. Data regarding predictors of CAD were collected from patient records as the secondary outcome measure. Statistical analysis was done using the R software. A P-value of <0.05 was considered statistically significant.

Results:

The prevalence of preoperative CAD in our study population was 79.7% (319/400 patients). None of the demographic and baseline clinical characteristics we studied predicted CAD in our study.

Conclusion:

We observed a significant prevalence of preoperative CAD among elective neurosurgical patients. None of the parameters we evaluated predicted CAD in our study.
Varied presentations of primary cutaneous lymphoma: A case series from a tertiary care center in South India
Authors: Shana Baby , Ambooken Betsy , Balakrishnan Sunitha , Neelakandan Asokan , Ajithkumar Kidangazhiyathmana
Published: March 2024

Background:

Recent studies indicate an upsurge of primary cutaneous lymphoma (PCL) in the Indian population. Of late, we too have come across varied presentations of PCL in relatively younger individuals. Hence, we decided to study the clinical and immunohistological profile of patients with PCL in our department.

Methods:

All cases diagnosed as PCL from October 2016 to October 2019 were included. Clinical details, complete blood count, peripheral smear, imaging, histopathology, and immunohistochemistry of skin specimens were analyzed. Lymph node biopsy and bone marrow studies were done in most cases. Human T lymphotropic virus-1 (HTLV1) serology was done in 10 cases.

Results:

Of the 24 patients with PCL, 12 were below 50 years of age. Twenty-three patients (95.8%) had T-cell lymphoma and only one had B-cell PCL. Mycosis fungoides (MF) (n = 17; 71%) was the most common type of PCL. There were two (8.3%) cases each of adult T-cell lymphoma/leukemia (ATLL) and Sezary syndrome. MF had varied clinical morphology at presentation and variable clinical outcomes. Both cases of ATLL had features of immunosuppression in the form of infective dermatoses.

Conclusion:

We observed an increased proportion of T-cell type of PCL, with the age of onset being relatively early. HTLV-1 positivity was noted in three out of the 10 cases tested. More studies are needed to determine the factors responsible for the younger age of onset of PCL and the role of HTLV-1 infection in the development of PCL.
Spinal lymphangiomas: Case-based review of a chameleonic disease entity
Authors: Sop François Yves Legninda , Benato Alberto , Izoudine Blaise Koumare , Khouri Kifah , Marangon Anna , Fraschetti Flavia , Lonjon Nicolas , Ferraresi Stefano
Published: March 2024

Purpose:

Lymphangiomas are benign hamartomas in the spectrum of lymphatic malformations, exhibiting multifaceted clinical features. Spinal involvement is exceedingly rare, with only 35 cases reported to date. Both due to their rarity and chameleonic radiologic features, spinal lymphangiomas (SLs) are usually misdiagnosed; postoperatively, surgeons are thus confronted with an unexpected histopathological diagnosis with sparse pertinent literature and no treatment guidelines available.

Methods:

Here, we report the case of a 67-year-old female who underwent surgery for a T6-T7 epidural SL with transforaminal extension, manifesting with spastic paraparesis. Then, we present the results of the first systematic review of the literature on this subject, delineating the clinical and imaging features and the therapeutic implications of this rare disease entity.

Results:

Our patient was treated with T6-T7 hemilaminectomy and resection of the epidural mass, with complete recovery of her neurological picture. No recurrence was evident at 18 months. In the literature, 35 cases of SL were reported that can be classified as vertebral SL (n = 18), epidural SL (n = 10), intradural SL (n = 3), or intrathoracic lymphangiomas with secondary spinal involvement (n = 4). Specific treatment strategies (both surgical and nonsurgical) were adopted in relation to each of these categories.

Conclusion:

Gathering knowledge about SL is fundamental to promote both correct preoperative identification and appropriate perioperative management of this rare disease entity. By reviewing the literature and discussing an exemplary case, we delineate a framework that can guide surgeons facing such an unfamiliar diagnosis.
A radiological parametric comparison of low-grade lytic spondylolisthesis to degenerative spondylolisthesis – A retrospective approach to establish its dysplastic origin
Authors: Pratap K. R. , Tandon Vikas , Goparaju Aditya Sunder , Aryal Aayush
Published: March 2024

Objectives:

This study aims to compare low-grade lytic spondylolisthesis (LS) and degenerative spondylolisthesis (DS) radiologically. In addition, it seeks to identify underlying similarities between LS and DS.

Methods:

This study included patients with low-grade single-level spondylolisthesis at L4–L5 or L5–S1. They were categorized into LS and DS. Radiological features, including pedicle height, width, transverse, and sagittal angle, as well as anterior vertebral heights (AVH) and posterior vertebral heights (PVH), were measured using T1-weighted magnetic resonance imaging.

Results:

The study involved 88 patients: 46 in the DS group and 42 in the LS group. In the LS group, the AVH was significantly higher than the posterior height at L4 and L5 (L4 PVH/AVH ratio 0.93 in LS vs. 0.96 in DS; L5 PVH/AVH ratio 0.84 in LS vs. 0.92 in DS), and pedicles were more medially oriented (L4: 19.62° in LS vs. 17.7° in DS; L5: 28.92° in LS vs. 26.47° in DS). In addition, at L5, the pedicle height (10.67 mm in LS vs. 11.48 mm in DS) and width (13.56 mm in LS vs. 14.37 mm in DS) were smaller compared to the DS group.

Conclusions:

Low-grade LS shows distinct radiological vertebral and pedicle anatomy compared to DS. Short and thin pedicles and wedge-shaped vertebrae in LS resemble DS, indicating its dysplastic origin.
En bloc resection followed by gluteal advancement flap for sacral Ewing’s sarcoma: A novel technique
Authors: Joseph Jeena , Prabhu Krishna , Jonathan Edmond , Jesudason Mark Ranjan , Gupta Ashish Kumar
Published: March 2024

Ewing’s sarcoma is a rare and highly aggressive bone tumor primarily affecting children and adolescents. It commonly presents in the pelvic and axial skeleton, with sacral involvement posing unique challenges due to its intricate anatomical location. This report details the case of an 18-year-old male with sacral Ewing’s sarcoma, emphasizing the diagnostic, surgical, and reconstructive aspects of management. The patient presented with lower back pain, lower limb weakness, and urinary incontinence, which prompted an extensive diagnostic evaluation. Magnetic resonance imaging and computed tomography scans revealed a large lytic mass extending from the S2 vertebra to the coccyx invading the presacral space. Biopsy confirmed the diagnosis of Ewing’s sarcoma, characterized by the EWS-FLI1 type 1 translocation. A multidisciplinary team comprising neurosurgeons, colorectal surgeons, and plastic surgeons was formulated. En bloc resection of the tumor, lumbopelvic fixation, and soft-tissue reconstruction using bilateral gluteus maximus advancement flaps were successfully performed. The procedure aimed to address both the oncological and functional aspects of the patient’s condition. Chemotherapy and radiotherapy were administered as adjuvant therapies. At 2-year follow-up, the patient was ambulating independently with no residual tumor on imaging. This case highlights the complex nature of sacral Ewing’s sarcoma and underscores the importance of a multidisciplinary approach. The described surgical technique, including the innovative use of gluteus maximus advancement flaps for soft-tissue reconstruction, contributes to reducing wound complications and promoting successful patient outcomes. The presented approach serves as a valuable addition to the armamentarium of treatment options for this challenging malignancy.
Venous pathology targeted surgical management in Hirayama disease: A comprehensive case series of nine cases exploring this potential etiology
Authors: Sharma Deepak Nandkishore , Yerramneni Vamsi Krishna , Yerragunta Thirumal , Gaikwad Govind B. , Rangan Vasundhara S. , Akurati Sasank
Published: March 2024

Objective:

Hirayama disease is a rare cause of cervical myelopathy predominantly affecting young individuals. The disease is classically characterized by muscle atrophy in the distal upper limbs. While various etiopathogenesis such as dural sac dysplasia, nerve root dysplasia, structural abnormalities of the spinal ligament, and venous dysplasia have been proposed, this study explores the potential role of venous pathology and surgical management on the basis of it.

Methodology:

This is a prospective descriptive case series of nine cases. The diagnosis was made based on the Huashan diagnostic criteria which includes clinical manifestation, imaging, and electrophysiology. In cases where magnetic resonance imaging (MRI) failed to demonstrate engorged veins, a computed tomography (CT) venogram of the cervical spine was used as an imaging tool. All patients underwent cervical laminectomy and coagulation of the posterior epidural venous plexus with or without laminoplasty. All the patients were followed up regularly; clinical improvement and neck disability index were assessed.

Results:

All nine patients were male and exhibited classical clinical features, electrophysiological abnormalities, and MRI findings except, in one patient where a CT venogram helped in establishing the diagnosis as the MRI was inconclusive. Postoperatively, all patients had neurological improvement and stabilization of the disease. All patients who underwent CT venogram and cervical spine X-ray in neutral and dynamic position demonstrated no recurrence of engorged venous plexus or significant instability except one patient developing kyphosis. One patient experiencing symptoms in the other limb underwent a second surgery.

Conclusion:

This comprehensive case series strongly supports venous pathology as a potential etiology of Hirayama disease. Surgical management with laminectomy and venous coagulation with or without expansile laminoplasty has delivered consistent improvement in neurological outcomes and long-term disease stabilization without the restriction of movements and lesser complications. However, further research is warranted to elucidate the mechanism underlying cervical venous dilatation.

Published: March 2024

This technical report illustrates the technique to perform computed tomography (CT)-guided bone biopsies in the body and dens of the axis (C2 vertebra) through a posterior transpedicular approach with the use of preoperative contrast-enhanced scans to highlight the course of the vertebral artery. The technique is presented through two exemplification cases: a pediatric patient with osteoblastoma and secondary aneurysmal bone cyst and one adult patient with melanoma metastasis. This case highlights the potential of the CT-guided posterolateral/transpedicular approach for performing safe and effective biopsies in the body and dens of C2, even in pediatric patients.
C1-C2 sublaminar taping for displaced odontoid synchondrosis fracture in an infant: A case report and novel surgical technique
Authors: Campbell Ryan J. , Yasutomi Motofumi , Nicholls Sarah , Mazepa Elizabeth , Ruff Stephen , Gray Randolph
Published: March 2024

Pediatric cervical spine injuries are rare, and the diagnosis and management can be challenging. Surgical intervention has been recommended in unstable odontoid synchondrosis injuries or those that have failed nonoperative measures. However, the literature remains sparse on the operative management of severe injuries due to the low incidence. An 18-month-old female sustained an unstable odontoid synchondrosis fracture from a motor vehicle accident. Due to ongoing instability after initial immobilization in a halo, the decision was made to proceed with surgical management. With the patient positioned prone and neural monitoring throughout, a posterior approach was utilized. Subperiosteal exposure of the C1 posterior arch was performed bilaterally. A spinal fixation band was passed under the right C1 posterior arch, around the C2 spinous process, under the left C1 posterior arch, and finally back under the C2 spinous process. The C1-C2 distraction was reduced using intraoperative imaging, and the sublaminar tape construct was secured and reinforced. The halo was then reattached. Postoperative recovery was complicated by a halo pin-site infection which was treated with oral antibiotics. The halo was removed after 3 months, following a computerized tomography that demonstrated union. X-rays at 6 months revealed anatomical alignment with the union. Surgery is recommended in pediatric odontoid synchondrosis fractures refractory to nonoperative management. Sublaminar taping of C1-C2 with a spinal fixation band has been demonstrated to be an effective surgical technique in the management of an unstable odontoid synchondrosis fracture.
Upper and lower cervical alignment parameters measured on supine magnetic resonance imaging with the occipital slope as a key marker of cervical alignment
Authors: Karabag Hamza , Iplikcioglu Ahmet Celal
Published: March 2024

Objectives:

Cervical spine alignment is evaluated by measuring the cervical angles or parameters on standing plain radiography. In this study, we aimed to evaluate mainly the upper cervical alignment and the correlation between upper and lower cervical sagittal parameters measured on supine magnetic resonance imaging (MRI).

Materials and Methods:

Cervical MRIs of 210 outpatients were reviewed to measure the upper and lower cervical sagittal parameters. Their mean values were compared with normative values measured on standing X-ray from the literature. Correlations between the parameters were analyzed using the Pearson’s correlation coefficient.

Results:

The C0 slope was correlated with all other parameters, except for the C2–7 sagittal vertical axis. The strongest correlations (r > 0.500) were between the CL and C2 slope, between the CO2 and C0 slope, and between the C2 slope and C0 slope.

Conclusion:

On supine MRI, the C0 slope is a key marker of cervical spinal alignment. A strong correlation was observed between the C2 slope and C0 slope; therefore, the relationship between upper and lower cervical alignment could be assessed using slopes on MRI.
The Study of COVID-19 Infection in Health-Care Workers Post-COVID Vaccination
Authors: Kinge Kirti Vinayak , Miranda Roshni C. , Chate Priyanka Dnyanoba
Published: March 2024

Background:

Indian Council of Medical Research report in April 2021 showed the incidence of breakthrough infection ranged from 0.02% to 0.04%, in spite of immunization with the COVID vaccine. Hence, the current study was done to find out postvaccination occurrence of COVID-19 in health-care workers (HCWs) and describe the characteristics of postvaccination illness.

Objectives:

The objectives of this study were to find out postvaccination COVID-19 illness characteristics such as severity, outcome, and required treatment in HCWs.

Subjects and Methods:

An analytical cross-sectional study was conducted over the duration of 3 months from July to September 2021 on 988 HCWs. The data were collected using Google Forms made available on social media platforms. Continuous data were analyzed by Mann–Whitney test and categorical variables using the Chi-square test or Fisher’s exact test.

Results:

Seventy-two (7.2%) out of 988 HCWs that participated in the study were tested COVID-19 positive (56.9% by reverse transcription–polymerase chain reaction, 38.9% by rapid antigen, and 4.16% by CBNAAT) postvaccination. The observed breakthrough infection was 3.84%. There were 18.3% and 5.6% cases of confirmed COVID-19 infection postpartial and complete vaccination, respectively (P = 0.000455). Those HCWs who had direct patient contact i. e., doctors and hospital staff 62 (6.7%) were more infected than other categories of HCWs (P = 0.010). Out of 72 cases who tested positive for COVID-19 infection, 52 were mild, 18 were moderate, and 2 were severe cases.

Conclusion:

Complete vaccination with two doses of the indigenous COVID vaccine is highly effective to bring down COVID illness-related hospitalization, severity, and death.
Facial mask-wearing prediction and adaptive gender classification using convolutional neural networks
Authors: Oulad-Kaddour Mohamed , Haddadou Hamid , Palacios-Alonso Daniel , Conde Cristina , Cabello Enrique
Published: March 2024

The world has lived an exceptional time period caused by the Coronavirus pandemic. To limit Covid-19 propagation, governments required people to wear a facial mask outside. In facial data analysis, mask-wearing on the human face creates predominant occlusion hiding the important oral region and causing more challenges for human face recognition and categorisation. The appropriation of existing solutions by taking into consideration the masked context is indispensable for researchers. In this paper, we propose an approach for mask-wearing prediction and adaptive facial human-gender classification. The proposed approach is based on convolutional neural networks (CNNs). Both mask-wearing and gender information are crucial for various possible applications. Experimentation shows that mask-wearing is very well detectable by using CNNs and justifies its use as a prepossessing step. It also shows that retraining with masked faces is indispensable to keep up gender classification performances. In addition, experimentation proclaims that in a controlled face-pose with acceptable image quality' context, the gender attribute remains well detectable. Finally, we show empirically that the adaptive proposed approach improves global performance for gender prediction in a mixed context.
A note on some $p$-adic analytic Hecke actions
Authors: Pan Lue
Published: March 2024

We show that the action of Hecke operators away from

p

on the space of (

p

-adic) overconvergent modular forms is (

p

-adically) locally analytic in a certain sense. As a corollary, the action of the Hecke algebra can be extended naturally to an action of rigid functions on its generic fiber. This directly determines the Hodge–Tate–Sen weights of Galois representation associated to an overconvergent eigenform and confirms a conjecture of Gouvêa.

Published: March 2024

Background: The association of the combination of body mass index (BMI) and weight change at admission with prognoses in patients with heart failure (HF) is unclear. Therefore, we investigated whether BMI and weight changes at admission affect mortality in patients with HF.Methods: This retrospective cohort study lasted 99 months, starting in April 2014, and included 4,862 patients with HF from a Japanese real-world database. Cubic and thin-plate smoothing spline analyses were performed to investigate the association of BMI and weight changes with mortality. The percentage weight change was calculated every 6 months. The study outcome was the presence or absence of death.Results: The patients’ mean age was 81.5±9.6 years, and 1,239 (25.5%) patients died. Cubic spline analysis revealed a negative correlation of BMI with mortality hazard ratio (HR) (BMI of 18.5 kg/m2 and 25 kg/m2; HR=1.3 [1.2–1.4] and 0.8 [0.7–0.9], respectively). Cubic spline analysis of weight change showed that weight loss tended to increase the mortality HR (each 6% decrease in weight change rate was associated with a 1.1 times higher mortality risk (95% CI [1.0–1.2]) Thin-plate smoothing spline analysis showed that the odds ratio (OR) negatively correlated with BMI (1-year mortality: BMI of 18.5 kg/m2, 22 kg/m2, and 25 kg/m2; OR at 0% weight change=1.5, 1.0, and 0.7, respectively; 2-year mortality: BMI=18.5 kg/m2, 22 kg/m2, and 25 kg/m2; OR at 0% weight change=1.4, 0.9, and 0.7, respectively).Conclusion: A low BMI in patients with HF was associated with a higher risk of mortality. Weight loss in patients, regardless of BMI, was associated with a higher OR for mortality.

Macrofaunal diversity and composition are essential to understanding the ecosystem structures and functions of mangroves in any dynamic estuarine coast. To understand the temporal distribution of macrofaunal community structures and diversity on the surface sediment in the intertidal mangrove forest next to the seagrass beds, this study was conducted at Punang-Sari-River estuary, Lawas, Sarawak (Malaysian Borneo), South China Sea. Sampling was done during post-monsoon, intermediate-September, pre-monsoon, and monsoon from July 2019 to February 2020. The mean macrofauna abundance was higher pre-monsoon, while Gastropoda Optediceros breviculum (L. Pfeiffer, 1855) was the most abundant (RA = 0.704). Important Species Index (ISI = 70.36) and percentage of contribution (64.97%) were also higher for this species than any other records from the site. The ANOSIM (Analysis of Similarity), Jaccard index and SIMPER (Similarity Percentage Analysis) analysis suggested that the highest species abundance similarity was observed between pre-monsoon and monsoon, while the highest dissimilarity was observed between intermediate-September and pre-monsoon (74.67%). Seasonal PCA, nMDS, and cluster analysis revealed that pre-monsoon and monsoon were comparable in species and individual abundance. The dominance (0.85) was found significantly higher (P < 0.0001) in intermediate-September, while Simpson (0.734), Shannon (1.56) and Evenness indices (0.528) were found higher in monsoon, followed by the higher Margalef richness indices (3.21) in post-monsoon. It was observed that the seasonal ecological parameters were found to be significantly (P < 0.05) different, including the temperature, salinity, rainfall, pore water nitrogenous compounds (NO2, NO3 and NH3-N), phosphorus compound (PO4) and micro minerals. The Canonical Correspondence Analysis (CCA) results suggested that ecological factors influenced several species. Considering the few studies on mangrove macrofauna in Malaysian Borneo, further research on their trophic structures and food web interactions is very important to disclose their overall characteristics and ecosystem functions.

The investigation of visitors’ perceptions of service performance is essential in identifying best practices for zoo management. This is critical to ensure a worthwhile experience for visitors and guarantee the long-term viability of the business. However, despite the current demands and expectations of visitors, the facets of zoo management remain under-researched. This study conducted a descriptive analysis to identify and prioritise the dimensions of perceived zoo service performance that require attention from Rabbitland Zoo management to make informed decisions towards better service offerings. The research findings revealed that location and ticket pricing received the highest mean score, indicating that both dimensions align with visitors’ demands. Although three dimensions of service performance, namely animal welfare, amenities, and educational-related needs, received mean scores between 3.50 and 3.95 (medium performance), these areas require attention from management as they are more likely to impact visitors’ willingness to pay for future zoo visits. In particular, animal-based educational projects can be a promising strategy to enhance school and family market attraction. Furthermore, future research may explore emerging perspectives on zoo management through expert opinions, uncovering the potential development of sustainable business models in zoo tourism.

In the 65 years since gaining independence, Malaysia’s political landscape has seen significant growth in student activism, particularly in terms of student political freedom in public universities. The 1960s and 1970s were regarded as the golden age of student movements in Malaysia, marking the peak of student political freedom. However, the enactment of the Universities and University Colleges Act 1971 (UUCA) suppressed all political activities by students. Recently, two important developments took place, namely the amendment of UUCA in 2019, which has allowed students to engage in political activities inside and outside the campus, and the implementation of Undi18, which has rekindled students’ political freedom. This study examines the views and understanding of the informants regarding the concept and practice of student political freedom. This study also highlights the existing values associated with student political freedom. The research design employed in this article is qualitative and conducted through a case study. We interviewed 15 informants from Universiti Sains Islam Malaysia, Universiti Tun Hussein Onn Malaysia, and Universiti Teknologi Malaysia. The concept of student political freedom was perceived as encompassing freedom of speech, freedom of associations, and the right to vote. Current practices of student political freedom include the use of social media platforms, political participation, and the formation of associations. In terms of student political freedom, the informants emphasised values of social responsibility, integrity, and intellectualism. In essence, this study presents findings on the current political scene in public universities post-UUC amendment and the passing of Undi18 bill, which purportedly create a more conducive democratic space for student political freedom.
