Repetitive Stress Injury can be regarded as a modern-day epidemic, a gift of industrialization. We have conducted a study to find the prevalence of musculoskeletal injuries in computer professionals with the aim to present data on the problem. The initial data was collected by a self-administered questionnaire enquiring about years of work and per day working hours, symptomatology with their duration and severity, their own appreciation of work output. These individuals were called up according to symptoms, assessed according to their symptomatology, relevant investigations and different modalities of treatment were advised. The study was conducted in one of the leading information technology company at our city. A total of 1159 questionnaires were collected. Six hundred and twenty-four (53.8%) had at least one positive symptom. 46.6% had stage 1 symptoms, 38.5% had stage 2 and 8.1% had stage 3 symptoms at the time of presentation. Two hundred and six patients were examined clinically by the senior author and a definitive clinicoanatomical diagnosis could be made only in 43 patients. Median age in our study group was 24 years. Ninety-eight (22.17%) of positive patients concluded decrease work output due to their symptoms, but only 50(11.3%) patients had consulted a doctor. Two hundred four (46.15%) of patients contributed their symptoms to an ill designed workstation. We conclude that repetitive stress injuries are a definitive problem in computer professionals. The median age in our study group was lower than many international studies. Nearly half of these patients were in stage 2 and stage 3 at presentation.

Published: April 2022

We present an extensive exploration of the impact of 29 physical parameters in the oxygen abundance for a sample of 299 star-forming galaxies extracted from the extended Calar Alto Legacy Integral Field Area Survey sample. We corroborate that the stellar mass is the physical parameter that better traces the observed oxygen abundance (i.e., the mass–metallicity relation; MZR), while other physical parameters could play a potential role in shaping this abundance, but with a lower significant impact. We find that the functional form that best describes the MZR is a third-order polynomial function. From the residuals between this best functional form and the MZR, we find that once considered the impact of the mass in the oxygen abundance, the other physical parameters do not play a significant secondary role in shaping the oxygen abundance in these galaxies (including the gas fraction or the star formation rate). Our analysis suggests that the origin of the MZR is related to the chemical enrichment evolution of the interstellar medium due, most likely, to the buildup of stellar mass in these star-forming galaxies.

We present statistical analysis of 11,200 proton kinetic-scale current sheets (CS) observed by the Parker Solar Probe during 10 days around the first perihelion. The CS thickness λ is in the range from a few to 200 km with the typical value around 30 km, while current densities are in the range from 0.1 to 10 μA m−2 with the typical value around 0.7 μA m−2. These CSs are resolved thanks to magnetic field measurements at 73–290 samples s−1 resolution. In terms of proton inertial length λ

. The magnetic field magnitude does not substantially vary across the CSs, and accordingly the current density is dominated by the magnetic-field-aligned component. The CSs are typically asymmetric with statistically different magnetic field magnitudes at the CS boundaries. The current density is larger for smaller-scale CSs, J

Published: April 2022

To address the global biodiversity crisis, standardized data that are rapidly obtainable through minimally invasive means are needed for documenting change and informing conservation within threatened and diverse systems, such as coral reefs. In this data paper, we describe 18S rRNA gene amplicon data (V1–V3 region) generated from samples collected to begin characterizing coral reef eukaryotic community composition at the Palmyra Atoll National Wildlife Refuge in the Central Pacific Ocean. Sixteen samples were obtained across four sample types: sediments from two sieved fractions (100–500 μm, n = 3; 500 μm-2 mm, n = 3) and sessile material scrapings (n = 3) from Autonomous Reef Monitoring Structures (ARMS) sampled in 2015, as well as seawater from 2012 (n = 7). After filtering and contaminant removal, 3,861 Amplicon Sequence Variants (ASVs) were produced from 1,062,238 reads. The rarefaction curves demonstrated adequate sampling depth, and communities grouped by sample type. The dominant orders across samples were polychaete worms (Eunicida), demosponges (Poecilosclerida), and bryozoans (Cheilostomatida). The ten most common orders in terms of relative abundance comprised ~60% of all sequences and 23% of ASVs, and included reef-building crustose coralline algae (CCA; Corallinophycidae) and stony corals (Scleractinia), two taxa associated with healthy reefs. Highlighting the need for further study, ~21% of the ASVs were identified as uncultured, incertae sedis, or not assigned to phylum or order. This data paper presents the first 18S rDNA survey at Palmyra Atoll and serves as a baseline for biodiversity assessment, monitoring, and conservation of this remote and pristine ecosystem.
Vegetation classification for northwestern Arctic Alaska using an EcoVeg approach: tussock tundra and low and tall willow groups and alliances
Authors: Wells Aaron F. , Swingley Christopher S. , Ives Susan L. , McNown Robert W. , Dissing Dorte
Published: April 2022

Aims: The USNVC is the standard for vegetation classification in the US and is part of the broader IVC. Recent work on the USNVC in Alaska established macrogroups, groups and alliances. Here we incorporate tussock tundra and low and tall willow (Salix) groups and alliances for northwestern Arctic Alaska into the IVC and USNVC classification. Study Area: The study area encompasses the Seward Peninsula, the western Brooks Range, and the northwestern foothills and Arctic coastal plain of Alaska. Methods: We used data from 2,087 relevé plots collected between 1992 and 2019 from northwestern Arctic Alaska to prepare a draft association classification using cluster analysis, ordination, and sorted tables. The draft classification was subject to peer review and subsequently refined. We fit the tussock tundra and low and tall willow associations into the USNVC using NMDS and GAMs to evaluate the patterns of environmental gradients against the ordination axis scores. Results: We identified eight tussock tundra and 37 low and tall willow associations. The associations fit in two classes, two subclasses, two formations, two divisions, three macrogroups, four groups, and 13 alliances. A description of the alliances, and a field guide to the northwestern Arctic Alaska tussock tundra and low and tall willow associations, including a dichotomous key and descriptions, is provided. Conclusions: Many of the tussock tundra and low and tall willow associations fit seamlessly within the USNVC, while some alliances had yet to be defined, and we have proposed new alliances here. In still other cases, we proposed a new group and recommend broadening the concept of an existing group using a data-driven approach. Since not all available data from Arctic Alaska were used in this study, we suggest continuing with a more comprehensive analysis to fulfill the gap at the alliance and association levels for Arctic Alaska.

Le conte créatif. Méthodologie thérapeutique pour les enfants victimes de traumatisme psychique
Authors: Gryson-Dejehansart Marie-Christine
Published: April 2022

La méthodologie exposée dans cet article a été élaborée voici plus de vingt ans pour et avec les enfants victimes de viols, l’ampleur des dégâts psychiques ayant été révélée par l’expertise judiciaire. La démarche théorique s’inspire de la phénoménologie des modes d’expression du sujet qui s’avèrent être à la fois révélateurs et moteurs thérapeutiques du trauma. La démarche pratique renvoie au constat de l’adéquation universelle du conte avec la mentalité infantile, tricotant un espace de fiction transitionnelle, facteur de résilience. L’expérience de création de contes avec les enfants victimes d’agressions psychocorporelles a objectivé les indicateurs de destruction et corrélativement les indicateurs de reconstruction psychique de l’identité. Cette méthode propose dix ancrages thérapeutiques à partir de balises narratives dûment décryptées. La thérapie par le conte créatif est applicable à toute autre problématique traumatique, en collectif ou en individuel.
Immédiateté médiatisée ou la médiation du langage théologique repensée par Rahner
Authors: Sendrez David
Published: April 2022

Les locutions « symbole réel » et « immédiateté médiatisée » véhiculent des choix à la fois métaphysiques et théologiques fondamentaux que Karl Rahner pose à partir du paradigme christologique. Leur force heuristique, pour considérable qu’elle soit, aboutit pourtant à une critique de la médiation du langage théologique. Parce que Dieu se donne en immédiateté médiatisée, le langage est capable d’un discours théologique dont la qualité est à la mesure d’une conscience paradoxale, celle de son impuissance. Ainsi, la théologie accomplit d’autant mieux sa mission qu’elle sait recourir à la blessure du langage.
Psychiatric and Behavioral Characteristics Among Male Adolescents With Sexually Acting Out Behaviors Admitted to a Residential Treatment Facility
Authors: McCarthy Logan Spencer , Smith James Matthew , Cayce Jonathan Matthew
Published: April 2022

One quarter of sexual offenses in the criminal justice system are committed by children and adolescents. Mental health conditions, trauma history, and relationship to the victim may play a role in sexually acting out behaviors (SAB). A retroactive chart review was performed to discover commonalities among 109 adolescent males with SAB admitted to a residential treatment facility. Variables of interest included prior mental health diagnoses, trauma history, full scale intelligence quotient (IQ), relationship to the victim, sex of victim, history of multiple offenses, and history of sexually acting out on an individual aged ≤4 years. Results indicated that 70.6% of the sample had a diagnosis of attention-deficit/hyperactivity disorder, 24.7% had a full scale IQ <90, 41.3% had sexually acted out on more than one victim, and 22.9% sexually acted out solely on males. Pearson's chi-square analysis indicated a non-significant relationship between diagnostic groups and victim characteristics. [

Published: April 2022

The purpose of the current study was to examine prediction power of psychological factors (i.e., alexithymia and psychological distress) on fibromyalgia among high school students. A cross-sectional, correlational design was used. Data related to alexithymia, psychological distress, and fibromyalgia were collected from 483 high school students from the northern part of Jordan using stratified cluster random sampling. Results showed that psychological distress is a significant predictor of fibromyalgia (odds ratio = 1.1,
p
< 0.001). Significant differences were found between males and females in relation to alexithymia (
t
= −4.87,
p
< 0.001), psychological distress (
t
= −6.0,
p
< 0.001), and fibromyalgia (χ
2
= 4.14,
p
= 0.04, phi = 0.07). Age was only significantly correlated with alexithymia (
r
= 0.06,
p
< 0.05). Given the relationship among psychological distress, alexithymia, and fibromyalgia, mental health professionals should carefully observe psychological disturbances among high school students. [

Influences of SMILE and FS-LASIK on Corneal Sub-basal Nerves: A Systematic Review and Network Meta-analysis
Authors: Jiang Xiaodan , Wang Yiren , Yuan Hao , Li Yuanting , Wang Hongmei , An Zhuoyu , Li Xuemin
Published: April 2022

PURPOSE:

To compare postoperative corneal sub-basal nerve density and number between small incision lenticule extraction (SMILE) and femtosecond laser–assisted in situ keratomileusis (FS-LASIK).

METHODS:

A search was made in PubMed, EMBASE, and the Cochrane library for prospective comparative studies. The analysis was divided into two parts: network meta-analysis and traditional meta-analysis of the studies directly comparing two surgical groups. Stata 16 (Stata Corporation) and Rev-Man 5.4 (Cochrane) software were used to analyze the data.

RESULTS:

Twelve studies (n = 775) were included. In the network meta-analysis, the SMILE group showed a significant increase compared with the FS-LASIK group in corneal nerve density at 1 month postoperatively (mean: 4.23; 95% CI: 0.06 to 8.39,
P
< .05), and in the number of corneal nerve trunks at 6 months postoperatively (mean: 13.25; 95% CI: 10.20 to 16.30,
P
< .05). In the traditional meta-analysis, the SMILE group showed significant improvement compared with the FS-LASIK group in corneal nerve density at 1 (weighted mean difference [WMD]: −2.05, 95% CI: −3.11 to −1.00,
P
< .05) and 3 (WMD: −0.90, 95% CI: −1.30 to −0.50,
P
< .05) months postoperatively, and in the number of corneal nerve trunks (WMD: −2.52, 95% CI: −4.91 to −0.14,
P
< .05) and corneal nerve branches (WMD: −2.80, 95% CI: −3.41 to −2.19,
P
< .05) at 1 month postoperatively.

CONCLUSIONS:

The corneal nerve injury in the FS-LASIK group was worse than that in the SMILE group. The corneal nerve recovery in the SMILE group was better at 3 months postoperatively. However, there was no significant difference in corneal nerve density and number between the two groups at 6 months postoperatively.

Authors: Vinciguerra Riccardo , Fernández-Vega-Cueto Luis , Poo-Lopez Arancha , Eliasy Ashkan , Merayo-Lloves Jesús , Elsheikh Ahmed , Madrid-Costa David , Lisa Carlos , Alfonso José F.
Published: April 2022

PURPOSE:

To evaluate the effect of the implantation of intracorneal ring segments (ICRS) in keratoconus on the dynamic corneal response (DCR) parameters obtained with the Corvis ST (Oculus Optikgeräte GmbH).

METHODS:

This prospective clinical study included patients who underwent ICRS implantation for keratoconus over a period of 1 year. On the day of the surgery and at least 1 month after ICRS implantation, the following measurements were made: corrected and uncorrected distance visual acuity, corneal tomography indices with the Pentacam (Oculus Optikgeräte GmbH), biomechanically corrected intraocular pressure (bIOP), Corvis ST DCR parameters, integrated inverse concave radius (1/R), deformation amplitude ratio (DA ratio), stiffness parameter at first applanation (SP-A1), stress–strain index (SSI), and highest concavity radius (HRC).

RESULTS:

Fifty-one eyes of 40 patients were included with a median follow-up time of 3 months (interquartile ratio [IQR]: 2 to 6 months). Statistical analysis showed that ICRS implantation did not affect corneal biomechanical measurements evaluated with the Corvis ST, which was demonstrated by non-significant changes in the SP-A1 (
P
= .637), 1/R (
P
= .647), HRC (
P
= .177), DA ratio (
P
= .735), and SSI (
P
= .501). Additionally, the results showed that bIOP measurements were not significantly affected by ICRS implantation (
P
= .113).

CONCLUSIONS:

ICRS implantation does not affect corneal biomechanical measurements in early follow-up.

Structure of split additively orthodox semirings
Authors: Huang Kaiqing , Chen Yizhi , Gan Aiping
Published: April 2022

The ideas of transversals are important to study algebraic structures which are useful for investigating semirings structure. In this paper, we introduce and explore split additively orthodox semirings which are special semirings with transversals. After obtaining some property theorems of split additively orthodox semirings, the structure theorem for them is obtained by using idempotent semirings, additively inverse semirings, and Munn semigroup. It not only extends and strengthens the corresponding results of Clifford semirings and split orthodox semigroups but also develops a new way to study semirings.

Published: April 2022

This article analyzes the assessment of the four development levels of the Digital Teaching Competence (DTC) to recognize the needs and formulation of challenges in training and educational innovation required in the pedagogical practices of university professors under the current context of the Covid-19 pandemic. The study used an empirical-analytical methodology with a non-experimental, transactional, descriptive design. The sample design was probabilistic, estimated with 95% confidence and 5% error among 252 teachers from various faculties of the University of La Guajira (Colombia). The selected instrument corresponded to the rubric's application to evaluate the university professor's digital teaching competence in Latin America. Among the study's significant results, we highlight that the rubric presented a high Cronbach's alpha reliability (α: 0.947). In the general assessment of DTC development, it was estimated that 78.2% of teachers are in the first two levels of DTC development assessment (Beginning and Middle). The evaluation rubric allows identifying challenges and opportunities that teacher training must address to advance the professional development of professors.

Published: April 2022

This paper probed deep into the motivation of students’ persistency for online learning from the perspective of user experience of online learning platforms, in the purpose of increasing user stickiness and formulating effective operation strategies in a targeted manner. Existing studies on the motivation of students’ persistency for online learning mostly focus on theories, while few of them have talked about the problem with the multiple mediation effect taken into consideration, for this reason, this paper aims to fill in this research gap and explore the mechanism behind the motivation of students to carry out online learning persistently under the multiple mediation effect. At first, this paper built an improved support vector machine (SVM) classifier and used it to predict the duration of students' online learning; then, it adopted a structural equation model to analyze the data of students’ willingness to continue online learning; after that, this paper gave a theoretical analysis on the motivation of students’ persistency for online learning under multiple mediation effect, and constructed a basic regression model for the said matter; at last, this paper employed experimental results to verify the prediction accuracy of the constructed model, and gave the corresponding estimation results.
Classification of Breast Cancer Tumors Using Mammography Images Processing Based on Machine Learning
Authors: Zahedi Farahnaz , Karimi Moridani Mohammad
Published: April 2022

Abstract— Using intelligent methods to identify and classify a variety of diseases, in particular cancer, has gained tremendous attention today. Tumor classification plays an important role in medical diagnosis. This study's goal was to classify breast cancer (BC) tumors using software-based numerical techniques. To determine whether breast cancer masses are benign or malignant, we used MATLAB version 2020b to build a neural network. In the first step, the features of the training images and their output classes were used to train the network. Optimal weights were obtained after several repetitions, and the network was trained to produce the best result in the test phase after several repetitions.

Because of using effective and accurate features, the method suggested here, which was based on an artificial neural network, delivered the diagnostic accuracy, specificity, and sensitivity of 100%, 100%, and 100%, respectively, to discern benign from malignant BC tumors, showing a better performance compared to previously proposed methods. One of the challenges for imaging-based diagnostic techniques in medicine is the difficulty of processing dense tissues. Breast cancer is one of the most common progressive diseases among females. Early diagnosis makes treatment easier and more effective. Using AI-based methods for automated diagnosis purposes can be valuable and have a reduced error rate because accurate diagnosis by manual means is time-consuming and error-prone.

Authors: B. S. Mahalakshmi , S. V. Sheela
Published: April 2022

Segmentation is one of the essential steps towards the identification of any object in the domain of image processing. In the area of hand-based biometric which is mainly deployed for a user authentication system, segmentation plays a critical role. A review of existing studies shows that there is a very less amount potential contribution in this regard. Therefore, this manuscript presents a novel optimization scheme towards palm geometry recognition system where segmentation process is the prime highlights for classification of hand and background considering a case study of finger recognition. Further, the proposed scheme uses masking operation where the Region-of-Interest section of hand is subjected to segmentation. Further proposed system uses machine learning approach (convolution neural network and Siamese Neural Network) to further assist in optimizing the segmentation performance. The experimental outcome of the study shows proposed system offers better accuracy compared to the existing system.
Robust Diagnostic System for COVID-19 Based on Chest Radiology Images
Authors: N. Sasikaladevi , A. Revathi
Published: April 2022

The proposed system is based on a diagnosis of COVID from x-ray images. In the respiratory system, 17 different viral infections are possible. Accurately discriminating COVID from other viral infections is necessary today as it spreads rapidly. The proposed system differentiates COVID infection accurately from other viral infections. The convolutional neural network (CNN) provides superior performance for disease diagnosis based on images in the deep learning era. In this chapter, to solve this issue, the authors propose a hypergraph-based convolutional neural network-based fast and accurate diagnosis system for COVID. In this work, the hypergraph represents the sophisticated features of a lung x-ray image to diagnose COVID. In-depth features are extracted from the x-ray images using residual neural networks. In order to discriminate COVID viral infection from other viral infections, the hypergraph fusion approach is used.
Autonomous Vehicle Tracking Based on Non-Linear Model Predictive Control Approach
Authors: Vu Trieu Minh , Moezzi Reza , Cyrus Jindrich , Hlava Jaroslav , Petru Michal
Published: April 2022

Autonomous driving vehicles are developing rapidly; however, the control systems for autonomous driving vehicles tracking smoothly in high speed are still challenging. This chapter develops non-linear model predictive control (NMPC) schemes for controlling autonomous driving vehicles tracking on feasible trajectories. The optimal control action for vehicle speed and steering velocity is generated online using NMPC optimizer subject to vehicle dynamic and physical constraints as well as the surrounding obstacles and the environmental side-slipping conditions. NMPC subject to softened state constraints provides a better possibility for the optimizer to generate a feasible solution as real-time subject to online dynamic constraints and to maintain the vehicle stability. Different parameters of NMPC are simulated and analysed to see the relationships between the NMPC horizon prediction length and the weighting values. Results show that the NMPC can control the vehicle tracking exactly on different trajectories with minimum tracking errors and with high comfortability.
Bilateral symmetrical spontaneous anterior capsule rupture of the cataractous lens in a child
Authors: Thrishulamurthy Chinmayee J , Saiprasad Deepthi
Published: April 2022

We report the management of a rare case of bilateral, symmetrical, and spontaneous anterior lens capsule rupture with total soft cataractous lens in a 7-year-old child. The patient had no other predisposing factors or systemic associations. Bilateral lens aspiration was done through the fibrosed capsular opening, which behaved like a stable capsulorhexis and hydrophobic intraocular lens was implanted. At 6 weeks follow-up, the patient had good visual outcome without any astigmatism. Although capsule rupture is reported in trauma, Alports syndrome or in hypermature cataracts, to our best knowledge this is the first case report of bilateral symmetrical spontaneous anterior capsule rupture in an otherwise normal child.

Published: April 2022

A 33-year-old female presented with sudden painless blurring of vision in both eyes. She gave a history of dog bite and had received two doses of intradermal anti-rabies vaccination 2 weeks prior to the onset of symptoms. Ophthalmological evaluation showed bilateral retrobulbar neuritis, superior nasal field defects in the right eye and vasculitis, and temporal hemianopia in the left eye. Extensive laboratory investigations ruled out all underlying infections, connective tissue disorders, and systemic vasculitis. Good response to pulse steroid therapy was noted. To our knowledge, this is the first case report of retrobulbar neuritis with retinal vasculitis following chick embryo cell-derived anti-rabies vaccination.

We report a 16-year-old female patient with diagnosis of xeroderma pigmentosum (XP), previously treated for simultaneous conjunctival squamous cell carcinoma in the right eye (OD) and conjunctival melanoma in the left eye (OS), showing progressive keratoconus during follow-up. Considering the risk of cross-linking treatment due to UV exposure in XP patients, an intrastromal corneal ring segment was implanted in the right eye. The patient was fitted with mini-scleral lenses that would promote corneal lubrication and provide the patient with better visual acuity than glasses. The patient has been followed-up for 1 year with no tumor recurrence and good vision.

We report a case of using synthetic cannabinoids (Bonzai) with hypertensive choroidopathy with bilateral multiple inkblot fluorescein leakage similar to acute central serous chorioretinopathy (CSC). The systemic blood pressure of the patient was 210/140 mm Hg. In fundus fluorescein angiography (FFA), there were multiple inkblot hyperfluorescent areas and an enlarging spot of fluorescein in the early phases and increased in the late phases similar to acute CSC in both eyes. All of the multiple focal hyperfluorescence areas in the FFA had disappeared, and hypofluorescent areas remained in their places at second month with systemic blood pressure regulation.

We present a very rare case of fungal orbital cellulitis which presented to us as a pus-discharging fistula below the medial canthus. The patient presented with signs of orbital cellulitis along with a pus-discharging fistula below the medial canthus with positive mucopurulent discharge from the puncta and fistula on syringing. It started with swelling near the medial canthus. The patient responded well on broad-spectrum antibiotics but developed a necrotic patch on the hard palate. The Magnetic resonance imaging (MRI) showed intraconal and extraconal involvement. Diagnostic nasal endoscopy (DNE) was done and the tissue was sent for Potassium hydroxide (KOH) mounting, culture, and histopathology. After the KOH mount showed budding-like yeast cells, the patient was started on antifungals and discharged when the repeat culture report showed no growth. Therefore, a high level of suspicion should be maintained for a fungal cause even in the presence of the pus-discharging fistula.
Tamoxifen maculopathy – A case with early optical coherence tomography changes
Authors: Kiranmayee Sai P , Kalluru Viswanath , Govindahari Vishal
Published: April 2022

Tamoxifen is an antiestrogen agent used as adjuvant therapy in breast carcinoma. Crystalline maculopathy due to tamoxifen toxicity, though rare, causes irreversible changes in the retina. High-resolution imaging like spectral-domain optical coherence tomography (SD-OCT) can detect early degenerating changes like crystalline deposits and cavitation in the retina. Early detection helps in the prevention of visual loss by prompt consideration in discontinuing or replacing the drug. Periodic screening with SD-OCT is essential as structural changes in the retina are noted even in asymptomatic patients receiving low-dose tamoxifen.

We report a case series highlighting clinical correlation of recurrence of Reis–Bucklers corneal dystrophy (RBCD) with histopathology (HPE), genetic analysis, and electron microscopy (EM). This was an interventional case series of three cases in three generations of one family. The index case was a 23-year-old male with bilateral recurrent RBCD following OD PTK and OS ALTK done 6 years earlier. His father had undergone OU PK. His 35-year-old sister and 9-year-old niece were also affected who underwent OU ALTK. Clinical examination, histopathological examination (HPE), and electron microscopy (EM) evaluation were done. The recurrence of RBCD was noted in one of the three members of the same family. Corneal examination showed a dense reticulate pattern of epithelial-stromal involvement. On HPE, disrupted Bowman's membrane and underlying abnormal subepithelial collagen staining positive with PAS and Masson's trichrome were noted. On EM, degenerated stroma with dense collagen fibrils in aggregates, dispersed among regular collagen fibrils, were noted. All four members showed TGFß1 mutation (chromosome 5q31) with Arg124Leu mutation. A trend toward more advanced presentation with increasing age of cases was noted. The clinical and pathological correlation was performed. Clinical correlation with HPE, EM with genetic analysis of RBCD is interesting with presentation severity varying in different generations.

Introduction:

Hyponatremia is a frequent finding in hospitalized patients and is associated with poor clinical outcomes. While hyponatremia is known to commonly occur in certain infections, its association with melioidosis has not been studied previously. We studied incidence and impact of hyponatremia on clinical outcomes in melioidosis.

Methods:

This was a retrospective analysis of a single-center hospital registry of culture-positive patients with melioidosis hospitalized during a 10-year period (January 01, 2010, through January 31, 2021). Hyponatremia was defined as serum sodium of <135 mmol/L, and severe hyponatremia as serum sodium <120 mmol/L. The association of hyponatremia with in-hospital mortality, need for intensive care unit (ICU) stay and mechanical ventilation was studied.

Results:

Of 201 patients with melioidosis, 169 (84.1%) had hyponatremia, with severe hyponatremia in 35 (17.4%) patients. Older age (adjusted odds ratios [OR] 1.03, 95% confidence intervals [CI]: 1.00–1.06; P = 0.049) and acute kidney injury (AKI) (adjusted OR 3.30, 95% CI: 1.19-9.19; P = 0.02) were independently associated with hyponatremia. Twenty-two patients had been evaluated for cause of hyponatremia and of these, 11 (50%) had syndrome of inappropriate antidiuresis. Severe hyponatremia was associated with in-hospital mortality (adjusted OR 3.75, 95% CI: 1.37–10.27; P = 0.01), need for ICU stay (adjusted OR 7.04, 95% CI: 2.88–17.19; P < 0.001) and mechanical ventilation (adjusted OR 3.99, 95% CI: 1.54–10.32; P = 0.004).

Conclusion:

Hyponatremia occurs in 84.1% of hospitalized patients with melioidosis. Older age and AKI are associated with a higher incidence of hyponatremia. The presence of severe hyponatremia is an independent predictor of in-hospital mortality, need for mechanical ventilation and ICU stay.

Chikungunya is a common tropical viral infection in India. The majority of patients have limited systemic manifestations. Neurological manifestations of chikungunya may be due to direct viral infection or immune mediated. We present a case of a 45-year-old male who presented with acute onset paraplegia with diminution of vision in the right eye. A detailed evaluation revealed a diagnosis of chikungunya myeloradiculitis with viral keratitis. The patient was treated with steroids followed by intravenous immunoglobulin and had a good recovery.

Published: April 2022

Introduction:

Catastrophic neurological decline, although exceedingly rare, takes a huge toll on pregnant population. In view of varied symptomatology and risks to the fetus, diagnosis and management of the neurological disorders in pregnancy is always a challenging task. The evaluation and management should be performed in a stepwise fashion and requires a multidisciplinary approach. Radiological imaging, especially magnetic resonance imaging (MRI), has revolutionized the diagnosis of these disorders, thereby exacerbating maternal and fetal outcome.

Aim:

The present study was conducted with the aim to characterize some of the significant neurological disorders complicating pregnancy and puerperium and to study the role of imaging, especially MRI, in differentiation and exclusion of various neurologic conditions, which helps an obstetrician to point to a specific diagnosis and management.

Materials and Methods:

Our study was an observational study conducted in the Department of Obstetrics and Gynecology in collaboration with the Department of Radiodiagnosis of GMC, Srinagar, from June 2018 to January 2020. The images were obtained with MRI and subjected for radiological interpretation.

Results:

A total of 750 patients were included in the study out of which 25 patients had neurological complications. Out of 25 patients, 13 were in the antenatal period and 12 were in the puerperium. There were 10 (40.0%) cases of posterior reversible encephalopathy syndrome (PRES), 6 (24%) cases of cerebral venous thrombosis (CVT), 3 (12.0%) cases of embolic infarcts, 2 (8.0%) cases of status epilepticus, 2 (8.0%) cases of pituitary apoplexy, 1 (4.0%) case of Wernicke encephalopathy, and 1 (4.0%) case of metastasis to brain (choriocarcinoma).

Conclusion:

Diagnosis of neurological complications of pregnancy and postpartum plays a crucial role in reducing fetomaternal morbidity and mortality. MRI stands above all imaging modalities in early diagnosis of these neurological complications, simultaneously taking care of fetal safety as well. The most common neurological complications that cause increased maternal mortality are PRES and CVT. Hence, early imaging can help in early and appropriate management of serious pregnancy-related neurological catastrophes.

Practice Problem: Nurse turnover can adversely impact any health system's financial performance and the clinical practice environment, and it is detrimental to patient safety and quality of care. PICOT: The PICOT question that guided this project was for nurses on a Labor and Delivery and Antepartum unit at a 382-bed community hospital in Austell, GA(P), does the utility of a contemporary shared governance structure in everyday practice (I) compared to the current shared governance structure (C) decrease nurse turnover rates (O) within four weeks (T)? Evidence: Shared governance permits the reduction of turnover and the intent to leave for nurses by promoting nursing autonomy and engagement, directly linked to decreasing turnover rates. Intervention: The contemporary shared governance structure facilitated nurse decision-making at the point of care in real-time and interprofessional team collaboration to effect change. Outcome: Nurse turnover rates compared four weeks prior and post-implementation showed a decrease from 68.26% to 63.08%, translating into a 5.11% drop-in turnover rates. Conclusion: The contemporary shared governance structure facilitated the direct care nurse's ability to make changes at the point of care in collaboration with the interprofessional team using a rolling idea-generating process integrated into everyday practice. The project was clinically significant as it transformed the direct care nurse's autonomy in their practice fostering a positive practice environment in four weeks. This project showed how nurse engagement could be improved when on-demand decision-making in the clinical area was facilitated, resulting in reduced turnover to yield better patient outcomes and overall organization performance.
