The discovery over the last several decades of low- and moderate-luminosity active galactic nuclei (AGNs) in disk-dominated galaxies—which show no “classical” bulges—suggests that secular mechanisms represent an important growth pathway for supermassive black holes in these systems. We present new follow-up NuSTAR observations of the optically elusive AGNs in two bulgeless galaxies, NGC 4178 and J0851+3926. Galaxy NGC 4178 was originally reported as hosting an AGN based on the detection of [Ne v] mid-infrared emission detected by Spitzer, and based on Chandra X-ray imaging, it has since been argued to host either a heavily obscured AGN or a supernova remnant. Galaxy J0851+3926 was originally identified as an AGN based on its Wide-Field Infrared Survey Explorer mid-IR colors, and follow-up near-infrared spectroscopy previously revealed a hidden broad-line region, offering compelling evidence for an optically elusive AGN. Neither AGN is detected within the new NuSTAR imaging, and we derive upper limits on the hard X-ray 10–24 keV fluxes of <7.41 × 10−14 and <9.40 × 10−14 erg cm−2 s−1 for the AGNs in NGC 4178 and J0851+3926, respectively. If these nondetections are due to large absorbing columns along the line of sight, the nondetections in NGC 4178 and J0851+3926 could be explained with column densities of log(N
H/cm2) > 24.2 and 24.1, respectively. The nature of the nuclear activity in NGC 4178 remains inconclusive; it is plausible that the [Ne v] traces a period of higher activity in the past, but that the AGN is relatively quiescent now. The nondetection in J0851+3926 and multiwavelength properties are consistent with the AGN being heavily obscured.

We present the study of multiwavelength observations of an unidentified Fermi Large Area Telescope (LAT) source, 4FGL J1910.7−5320, a new candidate redback millisecond pulsar binary. In the 4FGL 95% error region of 4FGL J1910.7−5320, we find a possible binary with a 8.36 hr orbital period from the Catalina Real-Time Transient Survey, confirmed by optical spectroscopy using the SOAR telescope. This optical source was recently independently discovered as a redback pulsar by the TRAPUM project, confirming our prediction. We fit the optical spectral energy distributions of 4FGL J1910.7−5320 with a blackbody model, inferring a maximum distance of 4.1 kpc by assuming that the companion fills its Roche lobe with a radius of R = 0.7 R
☉. Using a 12.6 ks Chandra X-ray observation, we identified an X-ray counterpart for 4FGL J1910.7−5320, with a spectrum that can be described by an absorbed power law with a photon index of 1.0 ± 0.4. The spectrally hard X-ray emission shows tentative evidence for orbital variability. Using more than 12 yr of Fermi-LAT data, we refined the position of the γ-ray source, and the optical candidate still lies within the 68% positional error circle. In addition to 4FGL J1910.7−5320, we find a variable optical source with a periodic signal of 4.28 hr inside the 4FGL catalog 95% error region of another unidentified Fermi source, 4FGL J2029.5−4237. However, the γ-ray source does not have a significant X-ray counterpart in an 11.7 ks Chandra observation, with a 3σ flux upper limit of 2.4 × 10−14 erg cm−2 s−1 (0.3–7 keV). Moreover, the optical source is outside our updated Fermi-LAT 95% error circle. These observational facts all suggest that this new redback millisecond pulsar powers the gamma-ray source 4FGL J1910.7−5320 while 4FGL J2029.5−4237 is unlikely the γ-ray counterpart to the 4.28 hr variable.

We use our new light curves, along with historical data, to determine the rotation state, photometric properties, and convex shape models of the targets of the Lucy mission (3548) Eurybates and (21900) Orus. We determine a retrograde spin for both targets, with sidereal rotation periods of 8.7027283 ± 0.0000029 h and 13.486190 ± 0.000017 h, respectively. The phase curves of both objects are nearly linear in the phase-angle range observable from Earth and lack a pronounced opposition effect. Unsupervised classification of these phase curves by the Penttilä et al. tool suggests that Eurybates and Orus belong to the C and D taxonomic types, respectively, thereby independently confirming past classifications based on their spectral slope. Time-resolved color-index measurements show no systematic color variations correlated with rotation for either target at the 1% level, suggesting that no variegation is present on a hemispherical scale for any of the objects. Comparison of the shape models with stellar occultation data available for the two objects from the program by Buie et al. allows us to resolve the longitude ambiguity of the orientations of the spin axes and derive unique pole solutions for both targets. Furthermore, scaling the shape models to match the occultation chords produces accurate sizes and geometric albedos for both objects. The derived surface-equivalent spherical diameters are D

Computer-Assisted Navigation Accurately Delivers Preoperative Targets for Acetabular Component Orientation During Direct Anterior Approach Total Hip Arthroplasty
Authors: Bradley Michael P. , Muir Jeffrey M. , Wang Sheila
Published: January 2023

Despite its success, total hip arthroplasty (THA) remains associated with potentially significant complications associated with component malposition. Preoperative planning can mitigate some of these potential concerns; however, the accurate intraoperative delivery of preoperative targets can be challenging. Computer-assisted navigation may assist with intraoperative target delivery, although the integration of these two technologies is relatively uncommon. We retrospectively reviewed cases of THA planned with a computed tomography–based preoperative planning software and performed with the use of an imageless, computer-assisted navigation system. Postoperative acetabular component orientation from radiographs was compared with preoperative targets and intraoperative navigation measurements. A total of 76 patients were included in the analysis. The mean anteversion target (20.0°±3.1°) did not differ significantly from the mean intraoperative navigation measurement (20.5°±3.3°;
P
=.30; mean difference, 2.2°±2.3°). The mean radiographic measurement (26.6°±6.5°) differed from the target by a mean of 7.5°±6.1° (
P
<.001). The mean inclination target (38.4°±1.9°) did not differ significantly from the mean intra-operative measurement (38.0°±1.5°;
P
=.20; mean difference, 1.3°±1.7°) but differed from the radiographic measurement by a mean of 5.2°±4.2° (41.8°±5.6°;
P
<.001). No adverse events were reported in the 90-day period following the index procedure. Our study demonstrated that an imageless navigation system can accurately deliver computed tomography–derived preoperative targets for acetabular component orientation. Differences noted on radiographs may be due to the difference in patient positioning for the postoperative imaging (standing) as compared with preoperative imaging or surgery itself (supine). [

A comment to improve tumor-treating fields therapy
Authors: Fioranelli Massimo , Sepehri Alireza
Published: January 2023

Recent investigations have shown that special frequencies and intensities of electromagnetic waves could control the differentiations of some types of cells. Using this fact, tumor-treating fields (TTFields) therapy has been proposed as a technique which uses alternating electric fields of intermediate frequency (~100–500 kHz) and low intensity (1–3 V/cm) to disrupt the cell divisions of tumors. However, this technique may have harmful effects on ionic liquids around normal cells. For example, electrodes could induce an extra electrical current within blood vessels. To observe these effects, we connected electrodes to a slide that includes water and some extra ions and put them under a 1000× microscope. We found that some ions, microbes and cells move toward negative electrons and some go away. These attractions of cells by electrodes could cause the destruction of the brain. We also found some electrical currents within the liquid emerge which absorb or repel water molecules and induce some bubbles. If these types of bubbles arise within the blood vessels, they can exert a force on the membranes of normal cells and destroy them. To avoid these problems, we suggest that electrodes should be replaced by some electromagnetic sender/receiver which emits some special frequencies. These frequencies could be absorbed only by blood vessels around the tumors because these vessels may be created only to provide the needed food for tumor cells and thus have a different potential and electrical current as compared to vessels around normal cells. Thus, these tumor vessels could act as the antenna for TTFields.
The dressing field method in gauge theories - geometric approach
Authors: Zając Marcin
Published: January 2023

Recently, T. Masson, J. Francois, S. Lazzarini, C. Fournel and J. Attard have introduced a new method of the reduction of gauge symmetries called the dressing field method. In this paper we analyse this method from the fiber bundle point of view and we show the geometric implications for a principal bundle underlying a given gauge theory.We show how the existence of a dressing field satisfying certain conditions naturally leads to the reduction of the principal bundle and, as a consequence, to the reduction of the configuration and phase bundle of the system.
Influence of chlorotrifluoroethylene on crystal structure and polymer dynamics of poly(vinylidenefluoride-co-chlorotrifluoroethylene) antibacterial copolymers
Authors: Kongcharoensuntorn Wisatre , Atorngitjawat Pornpen
Published: January 2023

The effect of chlorotrifluoroethylene (CTFE) on dynamic relaxations of poly(vinylidenefluoride-co-chlorotrifluoroethylene) films (P(VDF-CTFE)) containing 0, 10, 15 and 20% of CTFE was investigated via broadband dielectric spectroscopy (DRS) and dynamic mechanical analysis (DMA). The interpretation was accompanied by the crystal structure obtained from Fourier transform infrared spectroscopy, wide-angle X-ray diffraction, small-angle X-ray scattering and differential scanning calorimetry. Increment of CTFE contents caused reducing the degree of crystallinity but did not impact the long period, lamellar thickness, and amorphous layer thickness. Four dynamic processes were clearly observed in DRS spectra for the neat poly(vinylidene fluoride) and P(VDF-CTFE) which were attributed to the local motion of amorphous chains (β), the segmental relaxation of amorphous chains (α1), the local conformational rearrangement of the TGTGʹ conformation (α2) and the process associated with Maxwell–Wagner–Sillars interfacial polarization (αMWS). The extra relaxation was observed for P(VDF-CTFE), which was more likely associated to the molecular motion of CTFE chain segments (αc), correspondent with DMA results. These PVDF and P(VDF-CTFE) conducted as self-antibacterial materials.
Optimal harvesting strategy for stochastic hybrid delay Lotka-Volterra systems with Lévy noise in a polluted environment
Authors: Wang Sheng , Dong Lijuan , Yue Zeyan
Published: January 2023

This paper concerns the dynamics of two stochastic hybrid delay Lotka-Volterra systems with harvesting and Lévy noise in a polluted environment (i.e., predator-prey system and competitive system). For every system, sufficient and necessary conditions for persistence in mean and extinction of each species are established. Then, sufficient conditions for global attractivity of the systems are obtained. Finally, sufficient and necessary conditions for the existence of optimal harvesting strategy are provided. The accurate expressions for the optimal harvesting effort (OHE) and the maximum of expectation of sustainable yield (MESY) are given. Our results show that the dynamic behaviors and optimal harvesting strategy are closely correlated with both time delays and three types of environmental noises (namely white Gaussian noises, telephone noises and Lévy noises).

Published: January 2023

Vision-related quality of life (QoL) analyzes the visual function concerning individual well-being based on activity and social participation. Because QoL is a multivariate construct, a multivariate statistical method must be used to analyze this construct. In this paper, we present a methodology based on STATIS multivariate three-way methods to assess the real change in vision-related QoL for myopic patients by comparing their conditions before and after corneal surgery. We conduct a case study in Costa Rica to detect the outcomes of patients referred for myopia that underwent refractive surgery. We consider a descriptive, observational and prospective study. We utilize the NEI VFQ-25 instrument to measure the vision-related QoL in five different stages over three months. After applying this instrument/questionnaire, a statistically significant difference was detected between the perceived QoL levels. In addition, strong correlations were identified with highly similar structures ranging from 0.857 to 0.940. The application of the dual STATIS method found the non-existence of reconceptualization in myopic patients, but a statistically significant recalibration was identified. Furthermore, a real change was observed in all patients after surgery. This finding has not been stated previously due to the limitations of the existing statistical tools. We demonstrated that dual STATIS is a multivariate method capable of evaluating vision-related QoL data and detecting changes in recalibration and reconceptualization.

Published: January 2023

Rising income is driving the demand for online trading services across all income brackets. After the demand of online trading, many brokers have entered the cutthroat competition, high customer expectation, and dynamic technological changes have forced brokers to thrive on service quality. Online brokerage service as opted as an appropriate research framework for two main reasons. First, online brokerage is a service-intensive, fast-growing industry that is well suited for current research purposes. Second, there are few empirical studies measuring quality of service aspects and customer satisfaction and switching intention in the context of online securities. A relevant conceptual framework was outlined from extant literature which reveals an association between overall e-service quality, customer satisfaction and switching intension. Key dimensions were identified in the research which will add to the existing body of literature of service marketing. The finding of the research adds more depth in the body of literature of e-service quality in the online brokerage sector.
Attitudes, Awareness, and Use of the Consumer Protection Act Among Retail Furniture Consumers in the Umlazi Township, South Africa

Published: January 2023

The Consumer Protection Act (CPA) of 2008 was developed with the intention to protect consumers and promote fair dealings and responsible conduct of retailers in the marketplace. However, consumers continue to suffer in the marketplace due to defective products, unfair dealings, and poor service despite there being a CPA that was developed to protect their rights. Studies revealed a reduction in the number of registered complaints and an unchanged market environment for retail consumers pertaining to handling their consumer disputes. A quantitative study was conducted with a random sample of 95 retail furniture consumers who visited five furniture retail shops at Kwa Mnyandu Mall in the Umlazi township. Furniture retail consumers in Umlazi are aware of the CPA, however, they have reasonably less or no knowledge of the consumer rights contained in the CPA. Identified shortcomings in the use of the CPA to handle customer complaints is also explored. It was evident from the findings that retail consumers know that there is a CPA but they are unclear on how it is supposed to protect them when dissatisfied with a product.

Published: January 2023

In higher education, the role of assessment has evolved from serving only the purpose of evaluation of the outcomes of the learning process to assessment as part of the learning purposes. Summative or formative, the potential of assessment to facilitate learning is now recognised. Feedback is one of the most influential factors on learning but is also one of the least satisfactory elements of the student experience. How has interest in, understanding of, and implementation of feedback changed over time? What are the general characteristics of feedback implementation found in literature? To what productive directions might future research feedback on assessment take? To gain these insights, a systematic quantitative review of literature on feedback on written assessment in higher education was undertaken, revealing that feedback as a field of inquiry, despite burgeoning interest, remains nascent, mostly ‘stuck in old ways'.
Influence of Agriculture M(i) Services on Rice Planting Costs on Chinese Family Farms
Authors: Cheng Zhang , Hu Ni
Published: January 2023

Through a questionnaire survey on family farms in Chongqing, Shaanxi, Henan, Liaoning, and other provinces and cities, the authors compared and analyzed the factor importance ranking results of three models—multiple linear regression, SNA social network, and multi-layer perceptron neural network—indicating that different research methods have different calculation results. The results are similar and consistent, and the role of agricultural mechanization and informatization services in the three stages of rice planting—harvesting, plowing, and sowing—is significant. The high use of agricultural machinery services during the harvesting, tillage, and sowing stages of rice planting can reduce the cost of rice planting on family farms.

Published: January 2023

Removal of lettuce basal leaves is a technique used by the seed industry; however, the effects on seed production and physiological potential are unknown. Genetic dissimilarity is fundamental in the identification of individuals in terms of traits of interest, although it is rarely considered in relation to seeds that are tolerant to thermoinhibition. The aim of this study was to ascertain the relationship between defoliation of lettuce plants and seed yield/physiological quality, as well as the genetic dissimilarity among genotypes with regard to seed thermoinhibition. We used 35 lines of biofortified lettuce, the cultivars Uberlândia 10000, Belíssima, UFU MC BIOFORT1, and Everglades (tolerant to thermoinhibition), and Grand Rapids and Verônica (susceptible to thermoinhibition). The seed yield and physiological quality of the genotypes with and without defoliation were evaluated, artificially aged, and germinated at four temperatures in a factorial arrangement. The genetic dissimilarity was estimated by Tocher graphing and the UPGMA clustering method, based on the Mahalanobis generalized distance (D 2 ii). Four UFU genotypes and Grand Rapids had high seed yields. With removal of basal leaves, there was higher seed yield per plant and there was an effect on their physiological quality. The genotypes exhibited genetic variability for thermoinhibition, with UFU-86#2#1#1 and Everglades showing similar performance.
A noção de individuação em Jung e a educação
Authors: Seibt Cezar Luís
Published: January 2023

O artigo apresenta algumas das reflexões produzidas por Carl Gustav Jung no que se refere à relação entre o indivíduo e a sociedade, e verifica as contribuições que ele traz para entendermos melhor o nosso tempo e os processos de formação e o desenvolvimento humano. Essa polaridade tem importância fundamental na compreensão de nós mesmos e do nosso dever-ser, sobretudo porque tendemos normalmente para um ou outro extremo da tensão. Hoje, segundo seu diagnóstico, predomina a tendência da identificação com alguma função coletiva, definhando o desenvolvimento e aprimoramento pessoal. Importa, assim, primordialmente ajustar-se e identificar-se com um papel social oferecido pela comunidade da qual participamos; e a educação contribui com esse ideal de ajustamento e conformidade. O desafio, por isso, é a integração entre o mundo interno e o mundo externo, com o desenvolvimento da pessoa a partir da comunhão entre seus diversos aspectos, inclusive das suas sombras. É o processo de individuação, por meio do qual há a aproximação com o ideal arquetípico do Si-Mesmo. Logo, não se trata de negligenciar o desenvolvimento social, mas de associar a ele o apelo que vem da singularidade, integrando as duas exigências em um todo mais elevado.

Published: January 2023

O artigo tem como objetivo examinar os critérios éticos estabelecidos na legislação brasileira que orientam a pesquisa com seres humanos, nas teses defendidas e aprovadas entre os anos de 2017 e 2019, do Programa de Pós-Graduação em Educação de uma universidade pública localizada na região Sudeste do país com elevada avaliação pela Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). A pesquisa foi baseada na análise bibliográfica e documental. O trabalho encontra-se organizado em três partes: 1) procede a uma breve discussão sobre a ética nas pesquisas acadêmicas no Brasil; 2) aborda os marcos regulatórios da ética nas pesquisas em Educação no Brasil e 3) examina os procedimentos éticos utilizados nas teses de doutorado em Educação - objeto da investigação. Na análise e tratamento dos dados levantados, identificamos que, do total das 154 teses examinadas, 107 enquadraram-se nos critérios éticos e legais estabelecidos nas resoluções nacionais. Desse quantitativo, apenas 71 teses foram submetidas ao comitê de ética da universidade; 36 teses apresentavam a necessidade de submissão e não foram submetidas. Nessa análise genérica, conclui-se que os procedimentos éticos de pesquisa demandam maior difusão no meio acadêmico relacionado à pesquisa em Educação. Nesse sentido, reconhecemos e defendemos a importância de alimentar e aprofundar o debate sobre a ética na pesquisa a fim de construir marcos regulatórios específicos para as Ciências Humanas e Sociais e, particularmente, para a área da Educação, respeitando suas singularidades de metodologias e objetos de pesquisa.

Published: January 2023

Motor skills during childhood are extremely important for having an active lifestyle in adulthood; however, with the technological advance several plays and even the family environment have undergone changes, which affected the lifestyle adopted by the population. The present study aimed at investigating motor proficiency and blood pressure, as well as assessing the mediating role of nutritional status in such a correlation. This is a cross-sectional study carried out with 374 children aged 7 to 10 from the city of Maringá-PR. The nutritional status was measured by using the Body Mass Index (BMI) according to age and sex. The Bruininks-Oseretsky Test of Motor Proficiency, Second Edition, (BOT-2), was used to evaluate motor proficiency; the blood pressure was measured by using the Omron Deluxe HEM-7200® digital meter. The results showed a negative correlation between motor proficiency and body mass index and systolic and diastolic blood pressure. The analysis of structural equations revealed that there was no statistically significant direct impact of motor proficiency on blood pressure. However, when the mediation of nutritional status was included, a significant negative correlation between motor proficiency and nutritional status was seen, but positive in relation to systolic and diastolic blood pressure. In conclusion, motor proficiency has no direct influence on blood pressure; however, when mediated by nutritional status, the effect becomes significant. It is worth mentioning that the lower the motor proficiency and the higher the body mass, the higher the systolic and diastolic blood pressure was.

The purpose of this study was to measure and increase the awareness of the risk of ionizing radiation and its protection among medical staff (non-radiological staff) at Najran region. This study was conducted in selected hospitals and health centers in the Najran region, for the medical staff (both gender, age: 22-60 years), as they were classified into four groups doctors, nurses, administrative staff, and workers, in which their data were collected through a distributed questionnaire. A two-stage questionnaire, where the first phase included their general awareness of the risks of ionizing radiation and its protection, while the second phase included measuring their awareness post the educational week that was held on September 26, 2020 - October 1, 2020. The general result of the study showed insufficient awareness of the risk of ionizing radiation and its protection among medical staff, adequate awareness increase after implementing the educational week, and the estimated rate of increasing their awareness by 90% in different gender and ages groups. The group of males and females between the ages of 22 and 30 recorded the highest participation and awareness at both pre and post-educational weeks compared to other groups.It is important to improve the level of knowledge and awareness regarding radiation hazards and radiation protection to prevent injuries among medical staff in hospitals.

Physiological alterations in pregnancy may induce changes in salivary secretion and a predisposition to anxiety disorders. Clonazepam, a benzodiazepine, is recommended as the first choice for the treatment of anxiety disorders. To date, no studies have described the consequences of using this drug on the salivary glands of pregnant women. Therefore, the objective was to evaluate the alterations induced by exposure to Clonazepam in the salivary glands of pregnant mice. Twenty-two pregnant Swiss mice were divided into a control group (C) and a treated group (T), which received distilled water and 10 mg Kg-1 of Clonazepam, respectively, via gavage, daily, from the 5 to the 17th day of pregnancy. On the 18th day, euthanasia and collection of salivary glands were carried out, and the salivary glands were histologically processed and morphometrically analyzed under an optical microscope. The area, perimeter, and diameter of the acini and the thickness of the secretory ducts of each gland were measured. Parametric data (expressed as mean and standard deviation) were analyzed using the Student's t-test, and non-parametric data (expressed as median and interquartile range) using the Mann-Whitney test (p <0.05). Parotid glands’ acinar diameters (C: 44.1 ± 12.2 µm; T: 36.5 ± 7.8 µm; p =0.002) and ductal thicknesses (C: 16.9 [14.3-21.3] µm; T: 15.1 [13.4-16.3] µm; p =0.043) were statistically smaller in the T group than in the C group. No further alterations were found in other parameters from parotid glands, nor in submandibular and sublingual glands. It is concluded that Clonazepam induces morphological alterations in the parotid glands of pregnant mice. These alterations are probably associated with hyposalivation and xerostomia, already described as a common complaint among the users of benzodiazepines. Further studies are, therefore, suggested to assess the implications of these findings on pregnant women’s oral health.

Electroencephalogram (EEG) signal classification is a crucial and very difficult task. Meanwhile, extracting features that are representative and able to discriminate different types of EEG signals is a complex task. Such features are usually fed to machine learning algorithms to classify the EEG signals based on the extracted features. This paper proposed a highly accurate and real-time features extraction method that can be used to help physicians in detecting different types of seizures and states in EEG signals characterized by a set of features extracted from the power spectrum of the EEG window. This is achieved by applying the following four steps. First, the EEG signals dataset contains different classes of EEG signals: Normal Eye Closed, Normal Eye Opened, Focal Seizure, Non-Focal Seizure, and Ictal Seizure activities. Second, each EEG signal has a length of 4097 samples sampled with a sampling frequency of 173.6 Hz which resulted in 23.6 seconds in length, this signal will be truncated into windows (Sub-signals) with a length of 349 samples (Approximately 2 seconds) with a total number of 12 windows for each signal. Afterward, the Fourier Transform (FT) based power spectrum will be computed for each window, then a set of different features are extracted from each window's FT power spectrum, and these features are classified using different Machine Learning (ML) algorithms. The results showed that the proposed methodology yields around 98% accuracy for the five different classification scenarios using different ML algorithms. The suggested method is hence robust, fast, real-time, accurate, and simple.

Puçá fruits are native to the Cerrado biome yet little explored, presenting different varieties with distinct fruit peel colors. Although puçá fruits have been known to exhibit a good source of bioactive compounds, the phenolic profile of some varieties remains unknown. Based on this context, our research aimed to evaluate the chemical composition and bioactive compounds and characterize for the first time the phenolic profile in yellow puçá, brown puçá, and black puçá by high-performance liquid chromatography coupled with diode array detection (HPLC–DAD). The three puçá varieties contained considerable quantities of important food constituents, such as high concentrations of vitamin C, carotenoids and phenolic compounds. These fruits are mostly composed of phenolic acids, with p-coumaric acid being the major compound in all varieties, while ellagic acid was detected only in the brown puçá. Moreover, (−)-epicatechin was found only in the yellow puçá. This study is the first to report the identification of the phenolic profile in puçá. Moreover, our data indicate that the three fruit varieties present a promising chemical composition, suggesting that they may serve as potential sources of natural antioxidants. In addition, these findings can contribute to the establishment of puçá as a novel ingredient for formulations with functional claims.
Premenstrual Syndrome and Premenstrual Dysphoric Disorder
Authors: Paul Sayanti , Pal Arghya
Published: January 2023

Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) are two very closely related disorders that are seen in the overlapping territories of gynecology and mental health. Grossly, both these disorders are characterized by psychiatric and somatic symptoms that become prominent during the luteal phase of the menstrual cycle and cause significant impairment in the activities of daily living and usually spontaneously resolve shortly after the completion of the menstrual cycle. Researchers worldwide have been bemused by the simultaneous existence of these two diagnostic entities. The popular belief has been that the diagnostic entity of PMS has been mainly endorsed by the various gynecological societies worldwide, contrary to PMDD, which is a relatively newer diagnostic entity created by the American Psychiatric Association during the publication of the Diagnostic and Statistical Manual of Mental Disorders. The current article intends to trace the incredible journey of these entities from its inception to their current form and its utility in the current scenario and propose future implications.

Intraocular cysticercosis with central nervous system involvement is not that rare. We report a male child with a right-sided painful blind eye who had intraocular cysticercosis and granuloma in the left frontal lobe of the brain. There was an incidental finding of chronic inflammation in the choroid of that eye supported by histopathology. Immunohistochemistry for T-cells marker and B-cells marker was variable. The patient was treated with antiparasitic, anti-epileptic medications, and oral steroids subsequently.

Context:

Coinfection and superadded infections in patients with coronavirus disease 2019 (COVID-19) has been reported on multiple series. The emerging second wave of the pandemic has come with a lot of changes, especially in developing countries like India. One of such changes is sudden, significant rise in mucormycosis cases.

Aims:

To find out clinicopathological association of invasive mucormycosis with COVID-19 infection status and immunocompromised state.

Settings and Design:

A cross-sectional study done at a tertiary care centre.

Methods and Material:

All cases admitted in the dedicated mucormycosis ward between 1-06-2021 and 15-06-2021 were included in the study. The cases were admitted with suspicion of mucormycosis. The histopathological results were correlated with KOH mount and radiological reports. The clinicopathological association of occurrence of mucormycosis in post-covid and non-COVID patients along with other risk factors.

Statistical Analysis Used:

Odds ratio, chi square test were used to find the association using MS Excel 2010 and SPSS.

Results:

Thirty-six (81.82%) cases were of the post-COVID status, and 8 cases were non-COVID status. Out of 36 post-COVID patients, 33 (91.67%) showed evidence of invasive mucormycosis and of 8 non-COVIDpatients, 7 had evidence of mucormycosis (odds ratio = 1.57). Out of the total diagnosed cases of mucormycosis, 21 (52.5%) patients were known cases of diabetes mellitus (DM), and 7 (17.5%) cases of newly diagnosed hyperglycemia. Thirty (75%) patients out of 40 had some form of immunocompromised state. This shows statistically significant association of DM and immunocompromised state with the occurrence of mucormycosis in post-COVID patients (chi square value2 = 6.891, P value = 0.008). Twenty-five patients had the history of steroid use during the treatment of COVID-19.

Conclusions:

The infection with COVID-19 definitely increases the odds of contracting mucormycosis, but most of the cases had diabetes mellitus. So, it is possible that COVID-19 virus predisposes individuals to invasive fungal infection by precipitating DM.
