Published: November 2022

Introduction. Sugar consumed in reasonable quantities plays a beneficial role for the human body. In recent decades, however, it has been found that increased sugar consumption has negative effects on the health of the population.

Material and methods. The paper presents a synthesis of official international and national documents and bibliographic sources on the occurrence of certain non-communicable diseases (NCDs) as a result of excessive sugar consumption. A focused search of literature sources was conducted using the Google Scholar search engine, PubMed, Research for Life, and Medline databases. The criteria for selecting the items included health problems caused by excessive sugar consumption.

Results. Excessive sugar consumption contributes to the emergence of various NBTs such as circulatory system diseases, type 2 diabetes and a. Excessive sugar consumption has a major contribution to the phenomenon of overweight and obesity with its consequences. Excess sugar in the daily diet is one of the main causes of tooth decay. According to WHO recommendations, complex, multi-sectoral interventions are needed to reduce sugar consumption.

Conclusions. In order to prevent NCDs associated with the nutritional factor, especially with excessive sugar consumption, in the Republic of Moldova, it is important to implement cost-effective interventions both socially and economically.

Introduction: Although there are several previous publications related to risk factors of COVID-19 infection, in Benin there are very few data to explain the outbreak risk factors.

Material and methods: This case-control study, conducted from 14 September to 20 October 2020, aimed to identify the risk factors associated with COVID-19 infection in Benin. Questions on knowledge, attitudes, and practices related to COVID-19, sociodemographic characteristics, nutritional factors, medical history, housing and working conditions of respondents were asked through a questionnaire survey. Bivariate and multivariate logistic regression analyses were conducted to identify the factors associated with COVID-19. The statistical significance was set at 5%.

Results: In multivariate logistic regression, no handwashing device installed at the home entrance (ORa = 1.86; 95% CI [1.07-3.21]) or a device delivering only water (ORa = 5.57; 95% CI [1.98-15.65]), using permanently air conditioning at workplaces (ORa = 5.48; 95% CI [2.40-12.57]), less knowledge of protective measures (ORa = 1.41; 95% CI [1.08-1.84]) and no knowledge on the coronavirus incubation period (ORa = 4.19; 95% CI [2.37-7.44]) were identified as risk factors for COVID-19 infection.

Conclusions: Based on the findings of this study, a contextual response should prioritize strategies that will raise awareness and population’s knowledge of COVID-19 as well as preventive practices.
The experience of public hospital managers concerning the development and implementation of management strategies
Authors: Niculita Ana
Published: November 2022

Introduction. The strategies developed by the management of public medical institutions are based on state regulations in various areas: type of services provided, human resources, etc., decisions need to be coordinated with central and/or local public authorities, to which the institution is subordinated. However, it is necessary for the process of developing and implementing strategies to include a number of mandatory steps at institutional level, which must be taken by the institution's management.

Material and methods. The aim of the study is to assess the experience of public hospital managers in developing and implementing management strategies. An assessment grid was applied for this purpose. The questions were classified into six fields: setting management strategy, added value strategy, analysis of institutional environment, institutional policies and strategic objectives, resources needed, strategy assessment.

Results. In the absence of the regulation on the structure and main rules for the development of institutional strategies, the study demonstrates a very different approach of the top management regarding the strategic process in public hospitals.

Conclusions. The different and sometimes erroneous approach to strategy development by the top managers results in a weak institutional strategic process.

Published: November 2022

Introduction: COVID-19 is an infectious disease of International Concern, due to the widespread geographic impact and high transmissibility, causing severe illnesses. The quick detection of cases and isolating them has become very crucial, therefore many testing facilities were set-up for monitoring the spread of the SARS-COV-2 virus, at the early days of the coronavirus pandemic. From Biosafety aspect this study investigates a reliable risk assessment method to identify and mitigate the risks of COVID-19 testing facilities using Rapid diagnostic tests (POCT), in order to protect the staff, the people who got tested, the community and the environment.

Material and methods: Many techniques have been used so far for performing a risk assessment. In the present study, SWIFT analysis suitable for biosafety facilities and for risks of different magnitude, was used for identifying threats and hazards and to calculate the risks for COVID-19 testing facilities.

Results: Our analysis showed several initial and potential risks, which could lead to unwanted exposure or release of the SARS-COV-2, and/or unwanted infection of staff and patients. With minor adjustments of the testing facility, by creating standard operating procedures and awareness of the potential risks, most of the identified risks could be mitigated.

Conclusions: Our study demonstrated that when setting up a COVID-19 testing facility, a proper risk assessment should be part of the process, in order to ensure the safety of staff, patients, and the environment. Additionally, we proposed a number of multiple mitigation measures and recommendations, with the goal to reduce the risks during the rapid testing diagnostic procedure.
Using Social Media Pedagogies to teach School Mathematics in a selected Zimbabwean school during the COVID-19 Pandemic
Authors: Mutambara Lillias Hamufari Natsai , Tsakeni Maria
Published: November 2022

The COVID-19 pandemic tested teachers’ and learners’ resilience to continue teaching and learning with the limited use of traditional classrooms. What became apparent was the need to find alternative ways to maintain the interactions between the teachers and the learners. This study explored the teaching and learning of secondary mathematics during the COVID-19 pandemic based on the community of inquiry framework. An explorative single case study design with forty learners and seven teachers from a rural school in Zimbabwe as participants was used. The purposive selection of the participants was based on their experiences of emergency remote learning and classes where COVID-19 protocols were observed. Data were collected through open-ended and closed questionnaires given to learners and structured and semi-structured interviews conducted with teachers. The qualitative data were analysed through thematic content analysis techniques. The findings show that in the wake of limited access to sufficient educational technologies and internet connectivity, teachers had to find alternative ways to teach mathematical problems by using already worked-out examples and voice notes, thereby reducing the teaching presence and teacher-learner interactions. However, the reduction of the teaching presence was compensated by increased self-regulated learning as learners tried to make sense of the examples shared through social media tools. The study recommends building teachers’ technological and pedagogical knowledge to teach mathematics using cheap social media applications to improve the teaching, social and cognitive presence.

Aim: The purpose of this study is to present the importance of hemoperitoneum and retrospective analysis of tubal ectopic pregnancy cases treated in our clinic.

Material and Methods: This study respectively included 86 women who were diagnosed and treated for tubal ectopic pregnancy (EP) in our single-centre clinic between January 2012 and August 2013. Age, date of last menstrual period, human chorionic gonadotropin (β-hCG) level, the size and the presence of tubal EP masses, fetal cardiac activity and treatment procedures were evaluated and compared. The presence of hemoperitoneum for predictive treatment methods and factors that affecting the success of treatment methods were investigated.

Results: The mean age of the patients was 29.1±5.7 (16-41) years. Mean β-hCG level was 4448,5±8351,9 IU/L. Laparatomy was performed to 14 patients (16.3%), laparoscopy to 5 patients (5.8%), expectant management to 15 patients (17.4%). Methotrexate (MTX) treatment was given to 46 patients (53.5%) and laparoscopy was performed to 1 patient (1.2%) and laparatomy to 5 patients (5.8%) due to MTX treatment failure in 6 patients. Compared with the MTX treatment of tubal EP, the possible factors that affecting surgical management, such as the initial β-hCG level (p=0.004), whether there is hemorrhage in the abdominal cavity (p=0.03), the size of ectopic pregnancy mass (p=.005) and the presence of fetal heart activity (p
Numerical Simulations of Drainage Grooves in Response to Extensional Fracturing: Testing the Phobos Groove Formation Model
Authors: Cheng Bin , Asphaug Erik , Ballouz Ronald-Louis , Yu Yang , Baoyin Hexi
Published: November 2022

The long, shallow, parallel grooves that cut across the surface of the Martian moon Phobos remain enigmatic, with distinct implications for understanding the evolution of loose airless soils and the origin of Mars and its satellites. Phobos orbits deep inside the fluid Roche limit and is gradually spiraling in, creating global tidal strain, which leads to a model in which orbital decay is driving the formation of surface grooves on Phobos. Here we test this model by simulating the extension of a mildly cohesive regolith shell, driven by Phobos’s tidal strain imposed by orbital migration. Modeling Phobos as a rubble-pile interior overlaid by a cohesive layer, we find that the tidal strain could create parallel fissures with regular spacing, depending on the latitude and longitude. Fracture opening triggers drainage of upper loose material into these deep-seated valleys, which we show could lead naturally to the formation of groove-like structures. We map the prominent linear depressions on Phobos and find that some at midlatitudes correlate with the model-predicted groove orientations. Our analysis supports a layered heterogeneous structure for Phobos with possible underlying failure-induced fractures, as the precursor of the eventual demise of the de-orbiting satellite. However, we do observe significant areas showing absences and anomalies that are not consistent with the tidal fracturing model. The in situ observations on Phobos by the Mars Moons eXploration mission will conclusively determine the origin of its enigmatic striations.

Published: November 2022

Introduction: The most common infection in cholestatic infants is caused by human cytomegalovirus (HCMV). The aims were to detect the presentation of HCMV in cholestatic infants and to evaluate the concordance, sensitivity, and specificity between serology and polymerase chain reaction (PCR) of HCMV from liver biopsy and urine specimens.

Methodology: A descriptive observational study with a cross-sectional approach was conducted on 35 cholestatic infants with ethical approval. Specimens were liver biopsy, urine, and anti-HCMV serology. Liver and urine specimens were performed to nested PCR, followed by statistical analysis.

Results: PCR from the liver biopsy and urine specimen were positive in 74.3% and 85.7%, respectively. There was no concordance between IgM with the liver PCR, but there was a concordance between IgM with the urine PCR and between IgG with the liver and urine PCR. The sensitivity and specificity of IgM with the liver PCR were 46 % and 56%, respectively, with a diagnostic accuracy of 49%. While IgG sensitivity was 96% with a diagnostic accuracy of 80%. IgG sensitivity and IgM specificity compared with the urine PCR were 93% and 100%, respectively, with a diagnostic accuracy of more than 60%.

Conclusions: It demonstrates a high prevalence of HCMV DNA in urine and liver biopsy from cholestatic infants. HCMV PCR assay is more sensitive and specific than the anti-HCMV IgM, but IgG has high sensitivity and accuracy diagnostic. Therefore, serological examination is an option for diagnosing HCMV infection in cholestatic infants in developing countries with no PCR facilities.

Published: November 2022

Background : In the data analysis report it was found that in more than 80 countries the number of deaths due to COVID-19. The vaccine in Semarang City has been carried out, the Semarang City Health Service noted, there are 1,216,650 people who have received the first and second doses of the COVID-19 vaccine. The use of informed consent in the COVID-19 vaccine is still very low. It was found that 80% of COVID-19 vaccines used incomplete informed consent in every medical action. The purpose of this study was to determine the implementation of informed consent for COVID-19 vaccination in the Semarang City Region.
Materials and Methods: The carried out by means of a sampling non-probability sampling technique wasusing purposive sampling, namely a sampling technique with certain considerations made by the researchers themselves, based on characteristics, namely that they had already done a second dose of vaccine and also with the characteristics of the population that had been previously known. The sample is 100 people.
Results: Informed consent was explained to the patient, not all were informed, because there were still things that had not been explained, such as procedures for action, previous medical history. Informed consent of the COVID-19 vaccine was not given in the first and second doses. However, the majority are given in the first dose. The information provided by health workers at the time of vaccinating COVID-19 did not provide a complete explanation. The explanation to the patient is enough to explain what is important and more orally.
Conclusion: The implementation of COVID-19 vaccination can be carried out on men and women aged 18-60 years, the implementation of informed consent for COVID-19 vaccination is not in accordance with the applicable laws and regulations, namely the place is not in the right place. give informed consent for the COVID-19 vaccination, the information in the informed consent is still incomplete, so it has not been fully informed to patients. It is recommended to evaluate the implementation of informed consent to see the suitability of its implementation with the laws and regulations.
L’instance du nombre dans l’inconscient
Authors: Porge Erik
Published: November 2022

L’avènement du zéro opératoire, au vi e  siècle en Inde, fut un événement qui a transformé de fond en comble les opérations de comptage. Quelles en furent les conséquences pour un savoir des modalités de comptage de l’inconscient, c’est ce que Lacan tenta de résoudre. Déchiffrer les formations de l’inconscient, c’est reconnaître que le nombre démontre la puissance combinatoire de celles-ci (par exemple, celle de la condensation et du déplacement), affirme Lacan dès 1953. Tout au long de son œuvre, il associe le nombre à son approche du réel de l’inconscient comme savoir. Il rend compte de la nécessité d’une comptabilité spécifique des formations de l’inconscient. Il introduit dans ses calculs de nouveaux rapports aux nombres, tel le +1 pour le sujet et le nombre d’or auquel il identifie l’objet a. En même temps il récuse l’appellation de nombre pour le Un qu’il désigne comme « signifiant de l’inexistence » du sujet et dont il démontre la bifidité. Selon Lacan, tirant une leçon du nœud borroméen, le nombre un commence à trois. D’une façon générale il privilégie certains nombres en leur donnant une valeur algorithmique et il conclut que l’inconscient ne compte pas au-delà de six.
« L’esp d’un laps, soit puisque je n’écris qu’en français »
Authors: Hascoët Anaïs
Published: November 2022

Cet article fait suite à l’établissement d’une version critique en anglais de la « Préface à l’édition anglaise du Séminaire XI » de Jacques Lacan. Une première traduction de ce texte en anglais a été réalisée par Alan Sheridan qui est parue en 1977 dans l’édition en langue anglaise du Séminaire, Livre XI sous le titre The Four Fundamental Concepts of Psychoanalysis chez Hogarth Press. Sheridan a omis de traduire une partie de la première phrase de cette préface ; il n’a pas compris ce que Lacan voulait dire par « l’esp d’un laps » qu’il a réduit à « l’espace d’un lapsus ». N’y aurait-il pas là un trait d’esprit de Lacan ? Que faire des expressions que l’on ne comprend pas ou encore quand on est face à de l’intraduisible ? Cet écrit tente d’apporter des réponses à ces questions avec l’aide de travaux contemporains.
Le dieu inconnu
Authors: Schürmann Reiner , Blanchet Vincent
Published: November 2022

Reiner Schürmann a été appelé « l’un des philosophes majeurs du xx e  siècle » et « le continuateur peut-être le plus important d’une pensée de la mystique dans la lignée d’Eckhart et de Heidegger ». Nombre des chercheurs qui connurent Schürmann ou s’intéressent aujourd’hui à son œuvre souscriraient volontiers à de tels jugements, dans la mesure où cette œuvre déploie, comme nulle autre, les conséquences philosophiques et politiques de ce que Maître Eckhart et Heidegger appellent le délaissement ou le laisser être ( Gelassenheit ). Pourtant, presque rien n’a été dévoilé des deux bornes entre lesquelles s’inscrit le cheminement personnel de Schürmann quant au délaissement : sa découverte de ce concept – ou, plus exactement, de ce mode de vie – lors de ses études auprès des dominicains du Saulchoir, et la manière dont le délaissement a pu façonner sa mort trois décennies plus tard. Ces parties précoce et tardive de son œuvre, consacrées au délaissement et à sa mise en acte, sont toutefois cruciales pour comprendre le parcours de Schürmann et donc pour apprécier ce qu’il peut aujourd’hui offrir à la pensée et à l’existence. Si, dans ses œuvres publiées, Schürmann minimise l’importance de l’expérience chrétienne du délaissement, voire critique en elle une figure dérivée et même trompeuse de la  Gelassenheit , c’est bien elle qui lui a permis de s’engager sur son chemin de pensée. C’est elle aussi qui, à plus d’un titre, l’attendait au terme de son parcours, lequel apparaît alors comme un cercle faisant retour en soi.

Deep neural networks are becoming central in several areas of computer vision. While there have been a lot of studies regarding the classification of images and videos, future frame prediction is still a rarely investigated approach, and even some applications could make good use of the knowledge regarding the next frame of an image sequence in pixel-space. Examples include video compression and autonomous agents in robotics that have to act in natural environments. Learning how to forecast the future of an image sequence requires the system to understand and efficiently encode the content and dynamics for a certain period. It is viewed as a promising avenue from which even supervised tasks could benefit since labeled video data is limited and hard to obtain. Therefore, this work gives an overview of scientific advances covering future frame prediction and proposes a recurrent network model which utilizes recent techniques from deep learning research. The presented architecture is based on the recurrent decoder-encoder framework with convolutional cells, which allows the preservation of Spatio-temporal data correlations. Driven by perceptual-motivated objective functions and a modern recurrent learning strategy, it can outperform existing approaches concerning future frame generation in several video content types. All this can be achieved with fewer training iterations and model parameters.

Published: November 2022

This work focuses on the role taken by different forms of language during the first academic experience of symmetry by young children, in the context of primary school in France. We pay special attention to. A situation of introduction of symmetry in a class of CE1 (grade 7 or 8 years) was observed to this purpose. This paper aims to provide our analysis of this situation, which are grounded into a didactical theoretical framework enriched with semantic, discursive and metaphorico-conceptual analysis tools. This original approach allows us to understand the symmetry in all its complexity and to analyze finely the inter-influence of three dimensions (acting-talking-thinking) that characterize both the mathematical activity of the students and of the teacher.
Les moments d’exposition des connaissances analyses et exemples

Published: November 2022

We investigate several issues tied to the moments when the teacher introduces in his classroom the general, formal mathematical knowledge (the “course”). These issues are especially explained with reference to a theoretical hypothesis stated in terms of “pseudo-concepts”. Our didactical analyses take into account the contents of the course and its sequence of events. In particular we clarify several discursive “proximities” that may or may not appear during the sequence of events. Such proximities are particularly associated to explicit “closenesses” between students’ work over contextualized activities and the underlying general non-contextualized statement. These analyses are first illustrated on examples extracted from a course about graphical representation of functions (14-16 years old students). Secondly, we compare three types of courses on sequences and functions’ limits given to first-year university students: a textbook, a video and a lecture. The study reveals differences between diverse courses. It leads to clarify the issue about the specificity of the courses’ input in the students’ learning.

Investing in the stock market has never been an easy task. This paper develops a stock recommendation and trade assistance that uses the past performance of the stock to predict its future performance using linear regression model. Linear regression model has given an accuracy of 99.8% as compared to support vector machine (SVM) which resulted into an accuracy of 94.6%. Data set used under the study was extracted from the historic stock data of reliance industries limited (RIL). To analyze whether to buy or sell the stock, four financial algorithms, namely Bollinger bands, moving average convergence/divergence indicator (MACD), money flow index (MFI), and relative strength index (RSI) are employed to find the composite result. Moreover, sentiment analysis of the news depending upon the earning calls and the annual general meetings is done to provide an overall stock and market sentiment analysis. In-depth balance sheet analysis of the company is also done using various instruments to make the trade assistance more accurate. The values for WACC, D/E ratio, and NPV obtained are 14.99, 0.76, and 8.9 lakh crores for RIL.

Published: November 2022

This study analyzes the knowledge value chain of a center for continuing education that offers skill development programs for adult learners. It analyzes how the center can improve efficiency and capacity by effective knowledge sharing (KS) that requires both information and communication technologies (ICT) and the conducive organizational cultures. The case study methodology was used to study the factors that influence KS in an academic environment. KS depends on the type of knowledge, motivation, and opportunity to share. The results show that both knowledge management systems and a conducive organizational culture are needed to implement an effective KS strategy. Thus, the study focuses on the emergent approach, i.e., focusing on interpersonal dynamics and the nature of their daily tasks, and engineering or management approach, i.e., focusing on the infrastructure of KS. This study shows how systematic and organized KS can help an organization offer continuing education services effectively and improve performance in the competitive marketplace.

Authors: Park Jack Heesung , Linton Daniel , Thornber Ben
Published: November 2022

Computational fluid dynamics simulations of the flow around the ROtor Body INteraction (ROBIN)-mod7 fuselage with pressure-sensitive paint rotor are conducted using an immersed boundary method and an actuator surface model in OpenFOAM. The ROBIN-mod7 fuselage is represented by the immersed
boundary method, while the unsteady rotor is modeled using the actuator surface model. A comprehensive analysis of the generic helicopter configuration is carried out for the hovering flight condition; the isolated fuselage is simulated to provide its baseline aerodynamics, and the isolated
rotor and rotor–fuselage cases are studied to measure the rotor performance in hover and the fuselage effect on the performance. The validation of each test case is conducted against both experimental measurements and computational data from the literature. The surface pressure data
from the isolated fuselage case shows good agreement with the experimental measurements. Also, the rotor performance predicted on the isolated and installed rotors (rotor–fuselage) has excellent agreement with the reference data; in particular, the performance data on the installed rotor
agree with the experimental data better than the previous numerical study does. The fuselage effect has been analyzed by comparing the isolated rotor and rotor–fuselage datasets. The computational effort for different grid levels of each test case is provided. Overall, the results have
demonstrated an equivalent level of accuracy compared to the previous high-fidelity simulation results at their fraction of setup and computational expenses.
Comparative analysis of airway invasive aspergillosis and endobronchial spread of tuberculosis on high resolution computed tomography

Published: November 2022

The presence of tree-in-bud (T-I-B) pulmonary opacities on high resolution computed tomography (HRCT) in tuberculosis endemic areas is frequently regarded as a sine qua non for endobronchial tuberculosis (TB). That is not always the case, however. They can also be found in immunocompromised non-neutropenic patients with airway invasive aspergillosis (IA). Understanding the differences between the two conditions is thus critical for making an accurate diagnosis. This research aims to pinpoint those distinguishing characteristics. The study defines the distribution and morphology of T-I-B opacities and other ancillary pulmonary findings in the two conditions by performing a retrospective analysis of HRCT features in 53 immunocompromised patients with lower respiratory tract symptoms, 38 of whom were positive for TB on BAL fluid analysis and 15 confirmed IA by Galactomannan method. While the global distribution of T-I-B opacities affecting all lobes favoured TB (p=0.002), the basal distribution overwhelmingly favoured IA (p<0.0001). Morphologically, dense nodules with discrete margins were associated with TB, whereas nodules with ground-glass density and fuzzy margins were associated with IA. Clustering of nodules was observed in 18 TB patients (p=0.0008). Cavitation was found in 14 (36.84%) of TB patients but not in any of the IA patients. Peri-bronchial consolidation was found in seven (46.67%) of the IA cases and four (10.53%) of the TB cases (p=0.005, 0.007). The presence of ground-glass opacity and bronchiectasis did not differ significantly between the two groups. Not all T-I-B opacities on HRCT chest in immunocompromised patients in endemic TB areas should be reported as tubercular. Immunocompromised non-neutropenic patients with airway IA can be identified earlier with tree-in-bud opacities on HRCT chest, even in the absence of a nodule with halo, resulting in earlier and more effective management.

A total of 2,137 papers were found, and 20 papers were ultimately analyzed. Results: Most studies were conducted in the United States (55.0%) and in the medical field (45.0%), and most were experimental studies (35.0%). The results were organized across five categories: 1) preventive precautions, 2) characteristics of children's developmental stages, 3) encouraging voluntary participation, 4) continuity of interventions, and 5) teaching methods. Conclusion: Safety accident prevention interventions should cover the establishment of a safe home environment, include voluntary participation, and provide routine follow-up interventions. Additionally, practical training and teaching methods that incorporate feedback rather than a lectureoriented approach should be adopted.
Parenting experiences of mothers of moderate-to-late preterm children in South Korea: a qualitative study
Authors: Lee Sangmi
Published: November 2022

Purpose: This study investigated the parenting experiences of mothers of young children born moderate-to-late preterm (MLPT) in South Korea. Methods: In this qualitative study, semi-structured focus group interviews were conducted with 10 mothers of MLPT children from infancy to preschool age. The interviews were video-recorded, transcribed verbatim, and analyzed using qualitative content analysis. Results: Four categories resulted from the analysis of parenting experiences of mothers with young MLPT children, as follows: "becoming a mother of an early-born child", "difficulties as the primary caregiver for a high-risk child", "helpful social support, but still a lack of professional support for parenting a high-risk child", and "mothers and children growing together". Conclusion: Mothers of young MLPT children experienced difficulties due to concerns about their child's health, growth and development, and insufficient child-rearing support. Therefore, social support systems should be strengthened and more aggressive nursing strategies should be adopted for mothers of young MLPT children.
Influence of hardiness, mother-child interactions, and social support on parenting stress among North Korean refugee mothers: a cross-sectional study
Authors: Lee In-Sook , Jeon Jung-Hee
Published: November 2022

Purpose: This study investigated the factors that influence parenting stress, including hardiness, parent-child interactions, and social support, to provide basic data for developing a program to reduce parenting stress in North Korean refugee mothers.Methods: A descriptive study design was used. Data were collected between September and December 2021, and 123 North Korean refugee mothers participated.Results: The mean scores were 69.42 out of 135 for hardiness, 48.45 out of 144 for interactions, 47.32 out of 90 for social support, and 51.84 out of 90 for parenting stress. The parental distress score was higher than that of child-related stress. Hardiness was significantly related to North Korean refugee mothers' parenting stress. Multiple regression analysis indicated that the explanatory power for hardiness and the number of supporters was approximately 19% for parenting stress (F=6.84, p<.001). As such, the factors with a relatively strong influence on parenting stress were hardiness (β =-.40, p<.001) and having four or more supporters (β=-.27, p=.027). Conclusion: This study's findings suggest the need to identify ways to increase North Korean refugee mothers' psychological hardiness and encourage them to extend their sources of social support and enhance their style of parenting.

Published: November 2022

Intentional ingestion of organophosphorus compound (OP) poisoning continues to be a frequent reason for critical care admission in India. For the past 6 decades, the OP compounds used in India for the poisoning had effects on cholinergic and neurogenic fibers producing the respiratory and neurologic presentation. Recently, a less frequent OP poison has appeared which acts on cardiac sympathetic fibers with bradycardia and hypotension as presenting features. The shock which was nonresponsive to dopamine/dobutamine was identified as a major cause of death in patients with dimethoate poisoning in a large prospective cohort study. Severe dimethoate poisoning in contrast to other OP compounds has a high case fatality rate. There have been case reports from outside India. We report the first two cases with successful treatment of this toxicity in India.

Background:

A stroke is defined by the rapid emergence of clinical symptoms and focuses on evidence (applicable to individuals in a deep coma and those with subarachnoid hemorrhage) or widespread brain damage. The study aimed to evaluate the clinical characteristics of patients with acute ischemic stroke in a tertiary care hospital in North India.

Methods:

By analyzing case files and conducting patient interviews, information on the patients was gathered and evaluated. The study's inclusion and exclusion criteria were based on the 2018 American Heart Association and American Stroke Association (AHA/ASA) thrombolysis guidelines for acute ischemic stroke. Recent major trauma or major surgery within 14 days not involving the head, seizure at the onset of stroke, systemic malignancy, and pregnancy were excluded.

Results:

The study enlisted the participation of 76 patients who were divided into two groups. Patients in the one group were given tenecteplase, whereas the other group were given alteplase. Patients in the tenecteplase and alteplase groups were of different ages and had various other risk factors for hypertension, atrial fibrillation, diabetes, smoking, and previous stroke or transient ischemic attack. The risk factor distribution in both the groups was statistically significant for variables such as hypertension and diastolic blood pressure (P < 0.05). Stroke in internal carotid artery territory was present in 3 out of 42 in the tenecteplase group and 2 out of 32 in the alteplase group. Most patients in both the groups had a stroke of undetermined cause. Small vessel and large vessel strokes were found in 9.5% and 14.7%, respectively.

Conclusion:

In the development of stroke, there is a definite relationship between age and gender. A sedentary lifestyle, food, and obesity are risk factors for stroke. According to an AHA/ASA drug utilization analysis, most medicines were appropriate for stroke patients.

Published: November 2022

Background:

The use of mobile phones (MPs) in hospital halls, laboratories, intensive care units, and operating rooms is a common practice. There are no proper guidelines for the disinfection of MPs that meet hospital standards. This study investigated the bacterial contamination on MPs of health-care workers employed in tertiary healthcare Sher-i-Kashmir Institute of Medical Sciences (SKIMS) Srinagar, Jammu and Kashmir.”

Materials and Methods:

One-hundred and fifty-five health-care workers (57 doctors, 50 nurses, 35 technical staff, and 21 other employees) were included in a cross-sectional study performed from January 2018 to June 2018 at the SKIMS, Srinagar, Jammu and Kashmir. Social demographic characteristics (such as gender and occupation) and cell phone-related questions were gathered through a self-administered questionnaire (e.g., frequency of MP disinfection and use of the MP at work). Sample collection and processing were done correctly to avoid any bias.

Results:

Majority (79%) were working in different wards of the institute, followed by (51%) working in different laboratories and (8%) working in intensive care settings. The majority of the participants (42%) said they used their phone less than ten times per day; 33% said they used it 10–20 times/day. In terms of disinfection, 107 (69%) of the participants cleaned their MP occasionally, 31 (20%) never cleansed their phone, and just 17 (11%) regularly disinfected their phone. Out of 155 MPs sampled, 125 (80.6%) showed microbial growth, and 30 (19.4%) were free of microbial growth. Out of the total 125 positive samples, 51 (40.8%) were Gram-positive bacilli (which was considered as airborne contamination), 36 (28.8%) were Gram-positive cocci (GPC), 25 (20%) Gram-negative bacilli, 11 (8.8%) were mixed growth, and 2 (1.6%) were yeasts. Out of 36 GPC, Staphylococcus aureus was predominant, i.e., 15 (41.6%), followed by Enterococcus spp. 12 (33.3%), Coagulase-negative Staphylococci spp. 7 (19.4%), and Streptococci spp. 2 (5.5%).

Conclusion:

Almost all MPs were contaminated, with more than half of them harboring pathogenic microorganisms. It could pose a significant risk to both health-care personnel and patients in the form of nosocomial infections.
