Published: April 2024

Chylous fistulas (CF) are rare surgical complications and there is no standard treatment. This study presents the treatment modalities performed on patients who developed CF over a 10-year period. During the observation period, CF developed in 29 patients, 16 of whom were women. The mean age was 55.76± 13.48. Lymphatic duct injury was mostly seen in the abdomen (58.6%) and the most common reason was nephrectomy (20.7%). Extended lymphatic dissection due to malignancy was performed in 82.7% of all cases. Chylous leakage started postoperatively on 3.78±3.94 days (range: 1-19 days). Fasting, total parenteral nutrition (TPN), and somatostatin treatment were applied to all patients, and 75.8% of the fistulas were resolved completely with medical treatment. Surgical ligation of the lymphatic canal was performed in 7 patients. One was not successful and underwent percutaneous embolization of the thoracic lymphatic leakage cavity. All fistulas were resolved in 18.18±10.4 days. The resolution time and hospital stay were significantly higher in thoracic fistulas (p=0.017; p=0.003, respectively). In addition, malignant cases had longer resolution time (32.40±28.72 vs 16.27±11.25, p=0.036) and hospital stay (35.0±29.74 vs 16.25±14.05p= 0.002 respectively) than non-malignant. There was no chylothorax, chylous ascites, or recurrence at 20.55±22.88 months follow-up. Treatment of CF with fasting, TPN, and somatostatin analogs are effective. Other interventions such as surgical ligation with or without fibrin glue and interventional radiology treatments may be considered when conservative treatments fail.
The Relationship Between ESG Rating and Firm Value—Evidence from Companies Listed on Polish Capital Market in the WIG-ESG Index
Authors: Mikołajek-Gocejna Magdalena
Published: April 2024

The literature are abound with studies on the impact of environmental, social, and governance (ESG) factors on a company‘s value, or more broadly, on its financial performance. However, most analyses concern developed markets, mainly because the largest rating agencies operate in these markets, as well as because these are markets where ESG awareness and regulations have developed much faster. In developing markets, the number of studies in this area is disproportionately smaller. Therefore, the purpose of this article is to examine the relationship between the environmental, social, and governance ratings (ESGR) of Polish listed companies included in the WIG-ESG index and their value. This study covered 36 companies listed in WIG-ESG in the period of 2019–2023. We used market data, financial data from examined companies and ESG data provided by Refinitive. The empirical results were negative but a non-statistically significant influence of ESGR and a company’s value. Further analysis indicated that none of the sub-ratings (environmental rating (ER), social rating (SR) and governance rating (GR)) had significant impact on value. The Polish market does not seem to recognize the potential of ESG factors in building the long-term value of companies and believes that the costs of ESG factors outweigh the benefits. Investors seem to disregard or underestimate ESG criteria when valuing companies, which may seem irrational when looking at the long-term effects of ESG factors.

This article contributes to the existing literature by being part of the research on ESG factors and company value. The article expands the field of analysing the relationship between ESGRs and corporate value by examining this relationship not only using the overall ESGR, but also its individual sub-ratings. We also attempt to answer the question of where the channels of transmission of ESGRs on the value of the company are located, and which areas affect ratings. To the best of our knowledge, this is the first study of this type for the Polish market.
The Frailty of Models, the New Era, or a Rotten World of Consumers’ Financial Behaviour?
Authors: Warchlewska Anna
Published: April 2024

The aim of the article is to analyse the structure of consumer behaviour models and their applications to financial behaviour. The paper is theoretical in nature, examining generational breakdowns and selected trends in consumer behaviour. An analysis of the ‚rules‘ significant for types of consumer behaviour is conducted. Despite recently intensified theoretical and empirical analysis of consumer behaviour, a coherent research approach that integrates the issue of consumer behaviour with the specificities of the financial-services market has not yet been developed. Models remain frail, their functionality is still insufficient, and their applicability is constantly being altered by influences on consumer behaviour, including macro and microeconomic factors and the influence of scientific fields such as economics, sociology, psychology, management and anthropology. This article attempts to create a model that takes into account the general factors adopted in models constructed so far, along with the assumption that economic, cultural, social, personal, experiences, and other factors play a role in shaping and stimulating at least five variables: type of consumer from a particular generation (Cy); type of financial products and services (Xy); motivation (My); capacity (Capy); and opportunities (Oy).
Facts, values, and the epistemic authority of journalism: How journalists use and define the terms fake news, junk news, misinformation, and disinformation
Authors: Farkas Johan , Schousboe Sabina
Published: April 2024

In this article, we examine how journalists try to uphold ideals of objectivity, clarity, and epistemic authority when using four overlapping terms: fake news, junk news, misinformation, and disinformation. Drawing on 16 qualitative interviews with journalists in Denmark, our study finds that journalists struggle to convert the ideals of clarity and objectivity into a coherent conceptual practice. Across interviews, journalists disagree on which concepts to use and how to define them, accusing academics of producing too technical definitions, politicians of diluting meaning, and journalistic peers of being insufficiently objective. Drawing on insights from journalism scholarship and rhetorical argumentation theory, we highlight how such disagreements reveal a fundamental tension in journalistic claims to epistemic authority, causing a continuous search for unambiguous terms, which in turn produces the very ambiguity that journalists seek to avoid.
Executive functioning in children with ADHD Investigating the cross-method correlations between performance tests and rating scales
Authors: Olsen Kristoffer Dalsgaard , Sukhodolsky Denis , Bikic Aida
Published: April 2024

Objective

Replicated evidence shows a weak or non-significant correlation between different methods of evaluating executive functions (EF). The current study investigates the association between rating scales and cognitive tests of EF in a sample of children with ADHD and executive dysfunction.

Method

The sample included 139 children (aged 6–13) diagnosed with ADHD and executive dysfunctions. The children completed subtests of the Cambridge Neuropsychological Test Automated Battery (CANTAB). Parents completed the Behavior Rating Inventory of Executive Function (BRIEF) and the Children’s Organizational Skills Scale (COSS).

Analysis

Pairwise Spearman correlations were calculated between the composite and separate subscales of cognitive tests and rating scales. In secondary analyses, pairwise Spearman correlations were conducted between all composite scales and subscales, stratified by child sex and child ADHD subtype.

Results

The correlation analyses between composite scores yielded no significant correlations. The results when comparing CANTAB TO and BRIEF GE are r=−.095, p=.289, and r=.042, p=.643 when comparing CANTAB TO and COSS TO. The analyses between all composite scales and subscales found one significant negative correlation (r=−.25, p<.01). There are significant cross-method differences when stratified by the ADHD-Inattentive subtype, showing significant negative correlations (moderate) between CANTAB and BRIEF composite (r=−.355, p=.014) and subscales.

Discussion

It is possible that the different methods measure different underlying constructs of EF. It may be relevant to consider the effects of responder bias and differences in ecological validity in both measurement methods.

Conclusion

The results found no significant correlations. The expectation in research and clinical settings should not be to find the same results when comparing data from cognitive tests and rating scales. Future research might explore novel approaches to EF testing with a higher level of ecological validity, and designing EF rating scales that capture EF behaviors more so than EF cognition.
Psychometric Properties of the Parental Stress Scale in Swedish Parents of Children with and without Neurodevelopmental Conditions
Authors: Lindström Therese , Bergman Tiina Holmberg , Annerstedt Mathilde , Forster Martin , Bölte Sven , Hirvikoski Tatja
Published: April 2024

Background

Parents of children with neurodevelopmental conditions (NDC) are at risk of experiencing elevated levels of parental stress. Access to robust instruments to assess parental stress is important in both clinical and research contexts. Objective: We aimed to evaluate the psychometric properties of a Swedish version of the Parental Stress Scale (PSS), completed by parents of 3- to 17-year-old children, with and without NDCs.

Method

Main analyses were conducted on data from three independent samples: a community sample (n=1018), a treatment-seeking sample of parents of children with various disabilities (n=653), and a sample of parents of children with Attention-Deficit/Hyperactivity Disorder (ADHD) who themselves reported varying ADHD symptom severities (n=562). Additional analyses were enabled by the use of data from a complementary test-retest sample (n=337).

Results

The internal consistency of the PSS was good (Cronbach’s alpha, α=.87) and its test-retest reliability moderate (ICC=.66). The scale correlated in the expected direction with related constructs (r=.50–.56 in the community sample). An exploratory factor analysis found its internal structure to reflect two aspects of parental stress: Lack of Parental Rewards and Role Satisfaction (factor 1, α=.90) and Parental Stressors and Distress (factor 2, α=.85). The treatment-seeking parents of children with disabilities reported higher parental stress than community reference parents (p<.001; Cohen’s d=1.17). Moreover, we found that parents with high ADHD symptom severity reported higher parental stress than parents with low ADHD symptom severity (p<.001; d=0.39).

Conclusion

In summary, we found evidence in support of the reliability and validity of the PSS, which overall was judged to be useful as a measure of parental stress in a Swedish context. In addition, our results underline the importance of considering parental stress and related needs in assessments and intervention planning involving families of children with NDCs.

Authors: Wissik Tanja , Lušicky Vesna , Chiocchetti Elena
Published: April 2024

Knowing and collecting specialised terminology is part of legal translators and interpreters (LITs) daily work and professional competences. It is also an important quality aspect. In 2021, about 100 Austrian LITs participated in a survey aimed at collecting data on their knowledge of basic terminology principles and standards as well as their attitudes towards terminology work. Results show that terminology work is generally done under time pressure, rarely employing state-of-the-art tools, often disregarding terminological principles and without considering advantages related to data maintenance and exchange. The answers collected suggest that many LITs would benefit from hands-on training on tools and methods for sound and adequate terminology work targeted specifically at their professional group and activities.
Fleet Carrier in Name or Fact?: The Post-War Misinterpretation of USS Ranger as Unsuitable for Combat in the Pacific
Authors: Alvey James
Published: April 2024

Since World War Two, the USS Ranger (CV-4) has become perceived as incapable of combat in the Pacific Theater. Digitization has provided a new opportunity to examine its perception by commanders responsible for the carrier’s employment. These records reveal that the common perception of the carrier stemmed from diplomatic necessity, from an overworked bureau uneager for additional projects, and from commands eager to acquire Ranger for non-combat duty. Ranger was considered by the US Navy as fit for combat in the Pacific Theater during WWII, but other requirements overrode the need for one additional combatant carrier in the Pacific.

À la suite de la Seconde Guerre mondiale, l’USS Ranger(CV-4) était considéré comme un porte-avions incapable de combattre dans le théâtre du Pacifique. La numérisation a permis aux commandants responsables de l’emploi du porte-avions d’examiner cette perception sous un nouvel angle. Ces documents révèlent que la perception commune du porte-avions provenait de la nécessité diplomatique, d’un bureau surchargé de travail qui voulait éviter des projets supplémentaires et de commandements désireux d’acquérir le Ranger pour des tâches non combattantes. La marine américaine considérait le Ranger comme étant apte au combat dans le théâtre du Pacifique pendant la Seconde Guerre mondiale, mais d’autres exigences l’ont emporté sur la nécessité d’avoir un porte-avions de combat supplémentaire dans le Pacifique.
A Sailor’s View of Early Service in the Marine nationale on the Eve of the First World War
Authors: Madsen Chris
Published: April 2024

Conventional naval histories seldom consider the individual experiences of common sailors. Subaltern and other approaches to history from below use new sources to take a different viewpoint. In May 1913, recruit Georges Brucelle arrived in Toulon to start voluntary service in France’s Marine nationale. After completing common training, he specialized in torpedoes and undertook instruction to gain qualification. Assigned to a destroyer minelayer, Brucelle died along with many other of the ship’s crew during operations in 1915. Personal letters sent to his family reveal insights into the working and social lives of a French sailor just before the Great War.

Les histoires navales conventionnelles tiennent rarement compte des expériences individuelles des marins ordinaires.

En mai 1913, la recrue Georges Brucelle arrive à Toulon pour commencer le service volontaire dans la Marine nationale. Après avoir terminé une formation commune, il se spécialise dans les torpilles et entreprend une instruction pour obtenir une qualification. Affecté à un contre-torpilleur mouilleur de mines, Brucelle mourut avec de nombreux autres membres de l’équipage du navire lors d’opérations en 1915. Des lettres personnelles envoyées à sa famille donnent un aperçu de la vie professionnelle et sociale d’un marin français juste avant la Grande Guerre.
Features of the implementation of speech strategies and tactics in the slogan of television food advertising
Authors: Hu Ziming
Published: April 2024

The article is devoted to the study of speech strategies and tactics in the slogan of television food advertising. The slogan as an element of the advertising text plays a significant role in influencing the consciousness and behavior of the addressee. Slogans implement various speech strategies and tactics to ensure the success of advertising communication. The difficulty of studying this phenomenon lies in a short formulation with great strategic potential and its uncertain relationship with the main text of television advertising. The relevance of this study is related to the importance of the slogan in the advertising text and the prospects for studying speech strategies and tactics in the slogan of television food advertising. The article aims to identify the features of speech strategies and tactics in the slogan of television food advertising.  The method of linguistic and pragmatic analysis was used in the work, which makes it possible to identify speech strategies and tactics in the slogan of television advertising of food products and describe the linguistic features of their implementation. The novelty of the research lies in a comprehensive examination of speech strategies and tactics in the slogan, taking into account the main advertising text. As a result of the analysis, corporate slogan, product slogan and festive slogan were highlighted in television advertising. The slogans of television food advertising highlight presentation strategy, convincing strategy, persuading strategy and reminiscent strategy, as well as tactics and techniques within the framework of relevant strategies. The linguistic means of verbalization of techniques used within the framework of appropriate speech strategies and tactics in television advertising of food are described. The correlation of their implementation with the main advertising text has been established. The slogan of a TV advertisement usually implements several strategies and tactics at the same time. The implementation of the convincing strategy in a product slogan is relevant to the main advertising text. The implementation of other strategies in the slogan is not related to the main advertising text.

PURPOSE. The method of regression analysis of fires occurring at landfills of solid municipal waste (SMW) has established the relationship between the depth of the hearth and the time of fire elimination when using surface extinguishing agents. A multifunctional fire extinguishing system for municipal solid waste at a landfill with an aqueous medium in a metastable phase state is proposed. The efficiency of the proposed system is evaluated. METHODS. Methods of analysis and synthesis were used to evaluate the available data. To study the processes of volumetric fire extinguishing, the theory of branched-chain combustion processes was used. The objectivity of the theoretical dependencies found was confirmed by the experimental method. FINDINGS. The method of regression analysis of fires occurring at landfills of SMW has established the relationship between the depth of the hearth and the time of fire elimination. A comprehensive fire extinguishing system for SMW landfills using WSMPC with the possibility of autonomous operation is proposed. The system can also be used to prevent the occurrence of heterogeneous flame in the thickness of SMW. RESEARCH APPLICATION FIELD. The results obtained can be used to develop a fire extinguishing system for SMW at a landfill with an aqueous medium in a metastable phase state. CONCLUSIONS. The obtained results of the study will allow us to form a theoretical basis for describing the mechanisms of volumetric fire extinguishing of SMW landfills using WSMPC.
Algorithm for analysing actions of fire departments when extinguishing a fire
Authors:   Forensic expert institution of the federal fire service “Fire Test Laboratory” in the Irkutsk region, KASHIN Aleksander N.
Published: April 2024

PURPOSE. The author has analyzed scientific sources on models and algorithms for making managerial decisions on actions when extinguishing fires. Issues that have not received attention were identified. A model of decision-making by the fire crew chief at the stage of choosing the decisive direction upon arrival at the scene of emergency has been proposed. The purpose of the study is to develop an algorithm for analyzing actions of fire departments during examination of fire extinguishing organization on the example of eliminating combustion. For this purpose, the expert actions sequence during examining a fire extinguishing organization has been determined and considered. METHODS. For the purposes of the study methods of system analysis and comparison have been used. FINDINGS. The results of the scientific sources analysis have allowed the author to propose an algorithm for analyzing actions of fire departments during examination of a fire extinguishing organization, on the example of combat operations stage to eliminate combustion. The conditions that determine the decisive direction in a fire have been presented. After establishing the correctness of the decisive direction choice, the expert assesses the sufficiency of means and forces to carry out actions to extinguish a fire. The proposed flowchart for analyzing firefighting combat operations allows the expert to determine how many means and forces have arrived at the scene of fire extinction, whether additional means and forces were requested on time, сorrectness and efficiency of their use. To improve the analysis of combat operations, a draft algorithm for the actions of fire departments at the stage of combustion elimination when organizing fire extinguishing is proposed, which will make it possible to qualify violations of participants in extinguishing a fire during its elimination. RESEARCH APPLICATION FIELD. The proposed algorithm for analyzing combat operations can be used when conducting an examination of a fire extinguishing organization at the stage of eliminating combustion, as well as when analyzing and studying fires by fire department employees. CONCLUSIONS. The proposed algorithm can be used to carry out investigation of a fire extinguishing organization. Knowledge and understanding (expert) the entire process of combat operations to extinguish fires by a specialist on the example of a fire eliminating stage, will contribute to the completeness of the analysis when carrying out this type of investigations.

PURPOSE. The article deals with the issues of justifying possibility for using personal mobile device to search for people by Wi-Fi signal emission power. In case of fire individuals from technical staff at the facility under protection may not notice or hear the warning about fire and evacuation start. Having lost time to evacuate people may be cut off from main escape routes and become fire hazardous factors’ victims. METHODS. Using statistical model (ITU-R 1238) for calculations inside buildings and premises and data on routers location and placement order, an experiment has been conducted to locate a person when his mobile phone emits only residual signal power at this person’s specific location. FINDINGS. To simulate search for people and calculate matrix of signal power loss indoors and matrix of signal power levels at receiver input MatLab R2018 system has been used. Using two-way radio channel (based on Wi-Fi wireless network) is mandatory for system functioning to search for people in buildings, which allows not only identifying a person but also determining his exact location. It should be taken into account that dividing the room into cubes with dimensions 0.5×0.5×0.5 m makes it possible to determine person’s position in a particular place – lying or standing. RESEARCH APPLICATION FIELD. It is advisable to include study results in research and development work of EMERCOM of Russia research organizations and other ministries and departments involved in fire safety systems creation for critical protected facilities. CONCLUSIONS. Using the system for personal search during fires and emergencies will make it possible to locate people carrying mobile devices in real time and evacuate them to a safe zone when required.

PURPOSE. Advertising currently produced fire and rescue appliances demonstrates the advantages of their performance characteristics. This plays an important role in a market economy and highly competitive environment. At the same time, appliances for rescuing people must meet the requirements established for this specific product, i.e. have a document certifying compliance of the manufactured product with the legislative requirements in the field of technical regulation. Such a document is a compliance certificate or a compliance declaration. Using the example of a sectional evacuation appliance the modern process of documenting the compliance of a fire and rescue appliance with the requirements of technical regulations and standardization documents is analyzed. METHODS. When carrying out this work, theoretical methods such as classification, analysis, modeling and deduction were used. FINDINGS. The authors analyzed in detail individual forms of assessing the compliance of objects (products) under protection with fire safety requirements. It was established that a sectional evacuation appliance is to be assessed in terms of compliance with fire safety requirements in the form of confirming compliance of objects (products) under protection. It is hypothesized that the scheme for confirming the compliance of a sectional evacuation appliance will be carried out according to 4d scheme (for a batch of fire safety appliances or a single product), since choosing a scheme for declaring the conformity of fire safety appliances is carried out by the applicant on the basis of their own evidence and evidence obtained in a test laboratory. RESEARCH APPLICATION FIELD. The obtained research results may be useful to individuals or legal entities engaged in the production and (or) sale of means for rescuing people in case of fire in high-rise buildings. CONCLUSIONS. Available means of moving people to a fire-safe area in many cases may be the only way to save them. This opportunity is provided by special technical means that operate on external energy sources or work on the principle of smoothly reducing the energy of falling body weight from height. Taking this into account, it is especially important to assess the compliance of rescue appliances with the requirements of technical regulations, carrying out a full set of operations and conditions established by the conformity validation scheme before they are put into circulation.

PURPOSE. The article is devoted to the experimental study of thermophysical characteristics of steel on an experimental model – a metal plate of 600×600×5 mm, and to determining effective thermophysical characteristics of a fireproof coating made of a two-component epoxy composition under standardized temperature conditions. METHODS. In this work the finite element method implemented in the Ansys Mechanical software complex was applied for numerical thermotechnical calculation. The inverse heat conduction problem method was also applied for determining thermophysical characteristics of fireproof coatings. FINDINGS. As a result of the study the temperature fields were obtained in the cross section of steel structures with a fireproof coating under various fire temperature conditions. The conducted analysis showed that the discrepancies between numerical modeling and experimental data were satisfactory. RESEARCH APPLICATION FIELD. The results obtained can be applied for designing passive fire protection systems for building structures at construction facilities. As a result of the calculations, a number of values of fire resistance limits of structures with a fireproof coating from a two-component epoxy composition were obtained, taking into account the influence of standardized temperature fire regimes. All these data are put down in the tables of structures fire resistance ratings for three critical temperatures values based on which the corresponding nomograms were built. CONCLUSIONS. The study confirms the effectiveness of epoxy-based fireproof coatings to improve fire resistance of steel structures. Thermotechnical calculation and experimental modeling make it possible to determine the effectiveness of fireproof materials and justify their application in buildings and structures designed in accordance with standardized temperature fire modes requirements.

Clinical profile and photocontact sensitivity pattern in patients with cosmetic dermatitis: A prospective study
Authors: Monalisa Kumari , Sahoo Bijaylaxmi
Published: April 2024

Background

With the rise in cosmetic usage, adverse reactions related to cosmetics have also risen. Photocontact dermatitis to cosmetics is a challenging entity to diagnose and manage.

Objectives

To evaluate the clinical features and photocontact sensitivity patterns in patients with cosmetic dermatitis and establish their association based on patch and photopatch test results.

Methods

A prospective observational study, where 80 patients with a clinical diagnosis of cosmetic dermatitis were patch or photopatch tested (as per indication) with the Indian standard series, Indian cosmetic and fragrance series, and the patient’s personal product(s).

Results

A total of 104 positive reactions were observed in 57/80 patients, of which 50 were relevant to cosmetics usage. Sixty-five patients underwent a photopatch test, and 17 tested positive. Photosensitivity in patients was significantly associated with a positive photopatch test (p-value < 0.001). Various new photo-allergens were discovered, including propylene glycol, triethanolamine, chloroacetamide, isopropyl myristate, cetrimide and hexamine. Facial melanosis was a predominant clinical finding in 44 patients, with pigmented contact dermatitis detected in 19 (43.2%) of these cases.

Limitations

Patients’ personal products could not be tested on every patient. Chemical analysis of indigenous products and the individual chemical ingredients of the patient’s personal products could not be patch-tested separately. Phototesting was not performed in patients with photosensitivity.

Conclusion

In patients with suspected cosmetic dermatitis with history of photosensitivity or those with facial melanosis of unknown origin, a photopatch test is crucial to detect potentially hidden photo allergens. Many new photo allergens have emerged in the present study. Cosmetic companies should provide detailed information regarding each constituent of the cosmetic products.
Parasagittal meningeal hemangiopericytoma/solitary fibrous tumor: Two case reports and a literature review
Authors: Cekov Asen Hristov , Vezirska Donika Ivova , Tzekov Christo Tzekov , Nakov Vladimir Stefanov
Published: April 2024

Background:

Solitary fibrous tumor/meningeal hemangiopericytoma (SFT/M-HPC) is a rare neoplasm which accounts for around 1% of the intracranial masses. This pathology has a high risk for recurrence and metastasis to distant locations such as the liver, lungs, and bones. Precise diagnosis necessitates detailed histopathological examination.

Case Description:

We present two case reports of SFT/M-HPC. The first case is a 44-year-old female who presented with headache, nausea, vomiting, and frontal ataxia for several months. Imaging findings showed a large parasagittal extra-axial mass with compression of the frontal horns of both lateral ventricles. She underwent gross total resection with an uncomplicated postoperative period. The patient had no recurrent tumors or distal metastases in the follow-up period of 5 years. The second case is a 48-year-old male who presented with right-sided hemianopsia and hemiparesis. Computed tomography (CT) scans revealed a large parieto-occipital extra-axial mass with superior sagittal sinus engulfment and dislocation of the interhemispheric fissure. He underwent gross total resection with an uncomplicated postoperative period. Six years later, he presented with right-sided weakness. CT scan showed a multifocal recurrent mass at the previous location. He underwent subtotal resection with an uncomplicated postoperative period.

Conclusion:

SFT/M-HPC should be considered when presented with a meningioma-like tumor mass on preoperative imaging. Immunohistochemical study is crucial for the correct diagnosis. Strict long-term follow-up examinations and regular magnetic resonance imaging scans are key to preventing the appearance of metastases and large recurrent masses.

Published: April 2024

Background:

More than 700,000 people suffer from vertebral compression fractures attributed to osteoporosis, metastatic disease, or trauma each year in the United States, and undergo kyphoplasty. They are typical. These often undergo kyphoplasty to treat resultant pain or new neurological deficits. Here, we present three patients who, due to significant comorbidities, underwent kyphoplasty performed in the lateral decubitus rather than the prone position.

Case Description:

Three females, two with metastatic cancer and one with osteoporosis, presented with lumbar compression fractures and new accompanying pain and/or neurological deficits. Due to significant accompanying comorbidities, kyphoplasty was safely and effectively performed in all three patients utilizing the lateral decubitus rather than the prone position.

Conclusion:

Although vertebral kyphoplasties are typically performed in the prone position, here, we present three patients who, due to significant comorbidities, safely and effectively underwent kyphoplasties performed in the lateral decubitus position.

Published: April 2024

Depression and anxiety are two of the most prevalent mental health disorders worldwide, affecting millions of individuals across various age groups, and social categories. While the origins of these disorders are complex and multifaceted, recent advancements in Neuroscience provide valuable insights into the underlying mechanisms that contribute to the development and maintenance of mood and anxiety disorders. This review delves into the intricate interplay of neurobiological factors involved in these mental disorders, shedding light on the neural pathways, neurotransmitters, and structural/functional circuit changes that contribute to their manifestations. A special focus is given on new and upcoming insights in Neuroscience that emerge from a deeper understanding of the complex interplay of biological and environmental factors that takes place at a multi-scale level, from genes to behaviors.

We evaluated the impact of irbesartan (150mg once/day for 6 months) on kidney function, echocardiographic parameters and pre-clinical atherosclerosis indexes in 33 patients with newly onset of hypertension and without overt kidney dysfunction (Hypertensive Group–HTG). 15 age- and sex-matched, normotensive, healthy individuals (Normotensive Group–NTG) served as controls, without receiving any medication. After 6 months, HTG further improved its kidney function, flow-mediated dilation, diastolic function, left ventricle mass and left atrium volume implicating a cardio and reno-protective action in patients with newly onset of hypertension.
