Sleep Medicine in Portugal
Authors: Meira e Cruz Miguel , D’ Elia Cláudio , Feliciano Amélia
Published: March 2023

Sleep science and sleep medicine have seen massive growth in the last century in the world, and Portugal is not an exception. In the last 20 years, we have assisted an exponential increase in sleep disorders due to the increase in obesity, lifestyle (24/7 society), massive media utilization, and individual, family, and social commitments. Simultaneously, the scientific community, population, and media have focused on sleep and sleep disorders leading to a progressive need to invest in Sleep Medicine, at the clinical, research, and educational levels.

Despite the increase in diagnostic and treatment capacity of sleep disorders, the National Health Service, and private groups still do not fulfill the real needs. Still, in Portugal, sleep and its disorders are not fully taught in pre-graduated education. Additionally, sleep medicine is not an individual medical specialty and is shared by several medical specialties, such as Pneumology, Pediatrics, Psychiatry, Neurology, Otorhinolaryngology, Maxillofacial surgeons, and Dentistry, among others. Training programs of the different clinical specialties do not offer sleep medicine even as an option being mandatory only in the pulmonology curriculum.

Considering the importance of sleep for physical, mental, and social health, the growth of sleep disorders and their individual, familiar, social, and economic impact, sleep medicine should be one of the focuses of health development and investment in this century.

This chapter focuses on the historical insights and current development of Portuguese Sleep Science and Sleep Medicine fields.

Published: March 2023

Lithuania is a small country with a relatively short (31 year) history of independence in the modern era. Complicated history and geopolitical situation determined gaps in many socioeconomic spheres compared to other western European countries 30 years ago. Nevertheless, the country's ambitious goals and direction towards democratic values resulted in high recent socioeconomic ratings and acknowledgment among other European Union, NATO and Organisation for Economic Co-operation and Development members. The chapter presents short Lithuania’s geopolitical and healthcare system data, the current practice of sleep medicine, the practitioners involved, the availability of diagnostic tools and medications to treat common sleep disorders. It discusses challenges to the practice of sleep medicine: patient access to care, resource limitations and financial hardships, clinical and research knowledge gaps.

Somnology in Russia is a competency area for medical doctors from different disciplines. Most of them are cardiologists involved in private clinics located in the central and western parts of the country in the major cities. Some factors limit the development of somnology: differences between the regions, absence of legislative and regulatory absence of documents, lack of sleep-related services in the medical standards of health care, no insurance reimbursement, undergraduate sleep-related programs, and high cost of diagnostic and treatment equipment. Several professional societies focus on the development of different fields - clinical, fundamental, pediatric somnology, chronobiology and dream research. The postgraduate activities for medical doctors include different lectures online, web-based interactive educational modules on sleep disorders within the continuing medical education system, regular seminars in the major medical centers; certified (within other medical specialties) short training courses on sleep-disordered breathing and non-invasive ventilation and longer 36-72 hours courses in sleep medicine. The members of sleep-related societies perform various public activities all year round and in relation to the World Sleep Day. Diagnostic features of sleep practice include the unique use of rheopneumogram in Holter monitoring for very rough screening of apneas during sleep. Initiation of noninvasive ventilation therapy is more often started at home with the use of auto-CPAP machines. Various instrumental methods developed in Russia for insomnia treatment lack strong evidence. Support of the governmental institutions would help to solve present issues with regulatory standards in education and treatment in sleep medicine.
Natural Quorum Sensing Inhibitors: Potent Weapon to Control Bacterial Infections
Authors: Adhikari Manab Deb , Rai Nitya , Tiwary Bipransh Kumar
Published: March 2023

The emergence of antimicrobial-resistant pathogens is one of the most
serious public health threats that result mostly from the inappropriate and
indiscriminate use of conventional antibiotics for the treatment of infectious diseases.
These antibiotics mainly affect bacterial viability, resulting in the emergence of
resistant pathogens under this selective pressure. Thus, in turn, necessary to explore the
search for novel antimicrobial agents with a novel mechanism of action. The newer
class of antimicrobial agents, which target bacterial pathogenesis and virulence instead
of affecting bacterial viability, represents an alternate and interesting approach to
treating bacterial infections. Quorum sensing (QS) target is one of the main targets
among the various antivirulence and anti-pathogenesis approaches since it plays a
significant role in the expression of virulence and pathogenesis factors during the
infection process. The metabolites or compounds from plants and microorganisms have
been reported to inhibit quorum sensing. Due to the extensive diversity and complexity
of natural products as compared to conventional antibiotics, they show a wide range of
mechanisms of action. The use of natural QS inhibitors or quorum quenchers provides
a potential strategy and has been adopted as a model for the discovery of new
antimicrobial agents as quorum sensing inhibitors. In this chapter, the advancement in
searching for promising novel targets for the development of natural next-generation
antimicrobials to conquer infections caused by bacterial pathogens has been discussed
in detail.

Published: March 2023

The recent advancements in modern drug discovery as phytopharmaceuticals greatly impact the management and cure of various kinds of fungal diseases. Day by day, the demand for natural, novel anti-fungal drugs is increasing. Natural products are in more demand because they have fewer side effects. The induction of synthetic drugs has diverted researchers' attention toward natural products. Bioactive compounds from different natural sources have immense potential as therapeutic agents as well as antifungal properties. Many of the chemical constituents obtained from nature are easily accessible. The chemical constituents are supposed to be efficient with fewer side effects compared with synthetic drugs to prevent fungal diseases. Phytopharmaceuticals can alter and modulate biological systems without adverse effects and elicit therapeutic benefits. A systematic approach is elaborated in the recent chapter on the basis of their sources, chemistry and the functional aspects of bioactive chemical constituents, along with the recent developments in the field of pharmaceutical technology and research. It also touches upon phytopharmaceuticals as anti-fungal substances, a relatively new trend in drugs. They are acquiescent to transformation into novel dosage forms with relevance against fungal diseases. 
Host Factors: New Dimension in Antiviral Drug Targeting
Authors: Majee Prativa , Kumar Amit , Nayak Debasis
Published: March 2023

A spike in the emergence of several viruses is observed in the modern era,
including the present SARS-CoV2 virus. The continuous emergence of new viral
strains and growing resistance to the existing antiviral drugs urge new drug targets and
novel antiviral candidates against them. Host genes utilized by the viruses for their
proliferation, also known as host factors, have surfaced as a new antiviral strategy. If
affordable to the host cells, targeting the host factors may prove beneficial in
controlling viral infection. Host factors play an essential function in the viral life cycle,
and modulating their functions would thus impact viral replication. Often, the
interacting interfaces between the host and the viral proteins aim at antiviral
interventions. This aspect of antiviral drug development is in its inception phase.
However, with the advancement in molecular techniques identifying various viral host
factors, this field is believed to have immense potential as an antiviral drug targeting
strategy. This chapter briefly describes the host proteins' implication in viral biology
and how they can be exploited to treat viral diseases.

Minimally Invasive Treatments for Glioblastoma: A Review of Current and Emerging Surgical Technologies
Authors: Mezzacappa Frank , Davidson Caroline , Aizenberg Michele
Published: March 2023

Glioblastoma (GBM) is malignant, primary intracranial neoplasm associated with poor outcomes. Maximal, safe cytoreduction remains an important component of effective treatment for patients with this disease; however, some patients are not candidates for resection due to comorbid status, tumor location, or other factors. In this review, we aimed to describe minimally invasive surgical techniques that are emerging as important tools for improving safety and efficiency in GBM cytoreduction, including for patients with previously unresectable lesions. Specifically, we aimed to describe the commercially available tubular retractor systems and describe the available data regarding the benefits, risks, and utility of these retractors for patients with GBM. Additionally, we aimed to describe laser interstitial thermal therapy (LITT) and its use in GBM, including a description of the mechanism of action, commercially available systems, the steps in surgical implantation, available outcomes data, and future directions for the technology in this context. Finally, we aimed to review the use of MRI-guided high-intensity focused ultrasound (MRgHIFU) in GBM, including a description of its mechanism and data regarding efficacy in GBM. The availability and use of tubular retractors, LITT, and MRgHIFU provide clinically effective alternative methods for cytoreduction in GBM and are also emerging as important tools for the expansion of treatment to GBM that previously may have been classified as nonresectable. This review will assist in the development of an intimate knowledge of the use and utility of these techniques and is important for clinicians caring for patients with GBM.
Real-time Symptom Assessment in Patients With Endometriosis: Psychometric Evaluation of an Electronic Patient-Reported Outcome Measure, Based on the Experience Sampling Method
Authors: van Barneveld Esther , Lim Arianne , van Hanegem Nehalennia , van Osch Frits , Vork Lisa , Kruimel Joanna , Bongers Marlies , Leue Carsten
Published: March 2023

Background

The experience sampling method (ESM) holds advantages over traditional retrospective questionnaires including a high ecological validity, no recall bias, the ability to assess fluctuation of symptoms, and the ability to analyze the temporal relationship between variables.

Objective

This study aimed to evaluate the psychometric properties of an endometriosis-specific ESM tool.

Methods

This is a short-term follow-up prospective study, including patients with premenopausal endometriosis aged ≥18 years who reported dysmenorrhea, chronic pelvic pain, or dyspareunia between December 2019 and November 2020. An ESM-based questionnaire was sent out by a smartphone application 10 times a day during 1 week on randomly chosen moments. Additionally, patients completed questionnaires concerning demographics, end-of-day pain scores, and end-of-week symptom scores. The psychometric evaluation included compliance, concurrent validity, and internal consistency.

Results

Twenty-eight patients with endometriosis completed the study. Compliance for answering the ESM questions was as high as 52%. End-of-week pain scores were higher than ESM mean scores and showed peak reporting. ESM scores showed strong concurrent validity when compared with symptoms scored by the Gastrointestinal Symptom Rating Scale–Irritable Bowel Syndrome, 7-item Generalized Anxiety Disorders Scale, 9-question Patient Health Questionnaire, and the majority of questions of the 30-item Endometriosis Health Profile. Cronbach α coefficients demonstrated a good internal consistency for abdominal symptoms, general somatic symptoms, and positive affect, and an excellent internal consistency for negative affect.

Conclusions

This study supports the validity and reliability of a newly developed electronic instrument for the measurement of symptoms in women with endometriosis, based on momentary assessments. This ESM patient-reported outcome measure has the advantage of providing a more detailed view on individual symptom patterns and offers the possibility for patients to have insight in their symptomatology, leading to more individualized treatment strategies that can improve the quality of life of women with endometriosis.

Authors: Escobar Maria Fernanda , Montes Patricia Isabel , Sangiovanni Saveria , Libreros Laura , Alarcon Juliana , Madriñan Jorge
Published: March 2023

BACKGROUND

Due the unprecedented need for continuity in child health care during the confinement time subsequently to the Covid 19 pandemic, a high complex university hospital in the southwestern region of Colombia implemented a telemedicine program.

OBJECTIVE

We aim to describe the clinical experience using telemedicine for pediatric consultation and the behavior of routinary parameters evaluated during pediatric consultation

METHODS

A retrospective descriptive study was conducted. A total of 1.200 pediatric patients followed via telemedicine in clinical routine check-ups were included. Qualitative variables were summarized with absolute frequencies and percentages quantitative variables were presented with the measures of central tendency, and their respective measures of dispersion were represented according to a Shapiro Wilk test.

RESULTS

Of the 1.200 patients including boys and girls, 26% of girls and 27% of boys had some type of alteration, even though many caregivers did not give enough information about weight and height.

CONCLUSIONS

Our preliminary experience suggests that telemedicine provides support in the care of pediatric patients, however, it requires strategies to assess parameters measured routinely in the pediatric consultation. This study is a basis for developing further experience, strategies and research about caregivers and patient satisfaction, economic effect on families and the health system, and the role of telemedicine in pediatrics in low- and middle-income countries

Parent Perceptions of Trainees in Pediatric Care: Cross-Sectional Study (Preprint)
Authors: Strouf Motley Haley , Kerr Bradley , Sklansky Daniel J , Eickhoff Jens , Moreno Megan A , Babal Jessica C
Published: March 2023

BACKGROUND

Clinical experience and progressive autonomy are essential components of medical education and must be balanced with patient comfort. While previous studies have suggested that most patients accept trainee involvement in their care, few studies have focused specifically on the views of parents of pediatric patients or examined groups who may not report acceptance.

OBJECTIVE

This study aims to understand parental profiles of resident and medical student involvement in pediatric care and to use latent class analysis (LCA) methodology to identify classes of responses associated with parent demographic characteristics.

METHODS

We used data from a national cross-sectional web-based survey of 3000 parents. The survey used a 5-point Likert scale to assess 8 measures of parent perceptions of residents and medical students. We included participants who indicated prior experience with residents or medical students. We compared responses about resident involvement in pediatric care with responses about student involvement, used LCA to identify latent classes of parent responses, and compared demographic features between the latent classes.

RESULTS

Of the 3000 parents who completed the survey, 1543 met the inclusion criteria for our study. Participants reported higher mean scores for residents than for medical students for perceived quality of care, comfort with autonomously performing an examination, and comfort with autonomously giving medical advice. LCA identified 3 latent classes of parent responses: Trainee-Hesitant, Trainee-Neutral, and Trainee-Supportive. Compared with the Trainee-Supportive and Trainee-Neutral classes, the Trainee-Hesitant class had significantly more members reporting age <30 years, household income < US $50,000, no college degree, and lesser desire to receive future care at a teaching hospital (all P<.05).

CONCLUSIONS

Parents may prefer greater clinical autonomy for residents than medical students. Importantly, views associated with the Trainee-Hesitant class may be held disproportionately by members of historically and currently socially marginalized demographic groups. Future studies should investigate underlying reasons for trainee hesitancy in these groups, including the possibility of mistrust in medicine.

Black Lives Matter (2013) and the Civil Rights Movement (1960s) in the United States of America: A Same Story with a different name and Strategies
Authors: Faye Diome
Published: March 2023

The article examines with a fine-tooth comb the evolution of the civil rights movements of African Americans by making a comparative study between the civil rights movement of the sixties and the Black Lives Matter Movement in 2013. After the great hopes raised by Barack Obama's election in 2008, the series of savage and often unpunished killings of young African Americans between 2012-2020 sparked the ire of the black community gathered around the Black Lives Matter Movement. Although the ideological foundations of both movements remain the valorization of black lives in all areas of daily life in the United States, the Black Lives Matter Movement (2013) and the Civil Rights Movements of the 1960s did not embrace the same strategies of struggle and the same leadership. From the centralization of leadership of the sixties, the decentralization of leadership in the Black Lives Matter Movement has been more efficient and practical. The use of new information and communication technologies by the Black Lives Matter Movement has significantly contributed to the visibility and massification of the movement in the United States and around the world.
A model for the horst and graben structure of Midocean ridge crests based upon spreading velocity and basalt delivery to the Oceanic crust
Authors: Anderson Roger N. , Noltimier H.C.
Published: March 2023

La cresta de la dorsal del Pacifico oriental entre los 17° N a los 40° S se caracteriza por un horst central. Este rasgo se atribuye a! producto estacionario de una deriva constante en torno a la cresta, en que la varianza de la velocidad de inyección es menor que la varianza de la velocidad de deformación horizontal. Se elabora un modelo basado en estos dos parámetros, con el que se logra explicar tanto la topografía del horst central como de un graben central. Este último ocurre cuando en el modelo se postula una velocidad del fondo marino suficientemente baja, de modo que la varianza de la velocidad de inyección vertical es mayor que la varianza de la velocidad de deformación horizontal. Se supone que esto ocurrirá solamente cuando la deriva es intermitente, debido a la solidificación y ruptura alternada de la zona central de intrusión. Por lo tanto, la configuración del horst central sería la "normal". Dicho de otra manera, hay formación de graben central cuando el material asciende por la cresta sobre distancias mayores que las necesarias para acelerar el material de la cresta desde una velocidad horizontal nula hasta la velocidad de dispersión. De lo contrario, se forma un horst central.

Se midieron los contenidos de Uranio, Torio y Potasio usando la espectrometría de rayos - Ꝩ en algunas  rocas así como también  en aguas termales de la depresión central del  estado de Chiapas. Los resultados de estas mediciones demuestran que las muestras no tienen altos contenidos  de radiactividad, implicando posiblemente que los elementos radiactivos no son  responsables de la presencia de manantiales termales del área. Además, los cálculos  de balance térmico  de un modelo geológico que mejor representa  un cuerpo extrusivo ígneo emplazado en dicha depresión central, indican que éste  y otros cuerpos  pueden ser las posibles fuentes de calor  para las aguas termales  en el área.

Helicobacter pylori is main causative agent of acute gastritis and peptic ulcer disease. In certain population, this infection leads to gastric cancers viz., adenocarcinoma, and mucosal-associated lymphoid tissue (MALT) lymphoma. The objective of this study was to comparatively evaluate invasive (RUT) and non-invasive (IgM and IgG ELISA) methods for detection of H. pylori infection among patients visiting a tertiary care hospital. A total of 285 dyspeptic patients undergoing endoscopic examination were included in this study. From each patient one biopsy specimen and serum samples were collected. Biopsy specimen was subjected to RUT and IgM & IgG ELISA tests were performed using serum samples. H. pylori was detected in 127 (44.6%) and 126 (44.2%) cases by RUT and IgM ELISA, respectively. H. pylori were detected in 85 (29.8%) samples by IgG ELISA. Based on the combination of RUT and IgM ELISA test, total 128 (44.9%) patients were positive for H. pylori infection. Most of the positive cases belonged to 21-40 years age group (60 of 128) followed by 41-60 years age group (31 0f 128). All the three diagnostic methods viz., RUT, IgM ELISA and IgG ELISA used in this study showed a greater prevalence of H. pylori infection in female gender compared to male gender. In this study, sensitivity of both RUT and IgM ELISA was similar across different age groups and gender. The advantage of IgM ELISA over RUT is that it does not require endoscopy. Therefore, IgM ELISA could be considered as safe and an alternative method for detection of this pathogen.

Individuals with comorbidities (i.e., Diabetes Mellitus, hypertension, heart diseases) are more likely to develop a more severe form of coronavirus disease 2019 (COVID-19), thus, they should take necessary precautions to avoid infection with severe acute respiratory syndrome coronavirus–2 (SARS-CoV-2) and its emerging variants and subvariants by getting COVID-19 vaccination and booster doses. In this regard, we used text analytics techniques, specifically Natural Language Processing (NLP), to understand the perception of Twitter users having comorbidities (diabetes, hypertension, and heart diseases) towards the COVID-19 vaccine booster doses. Understanding and identifying Twitter users’ perceptions and perspectives will help the members of medical fraternities, governments, and policymakers to frame and implement a suitable public health policy for promoting the uptake of booster shots by such vulnerable people. A total of 176,540 tweets were identified through the scrapping process to understand the perception of individuals with the mentioned comorbidities regarding the COVID-19 booster dose. From sentiment analysis, it was revealed that 57.6% out of 176,540 tweets expressed negative sentiments about the COVID-19 vaccine booster doses. The reasons for negative expressions have been found using the topic modeling approach (i.e., risk factors, fear of myocardial fibrosis, stroke, or death, and using vaccines as bio-weapons). Of note, enhancing the COVID-19 vaccination drive by administering its booster doses to more and more people is of paramount importance for rendering higher protective immunity under the current threats of recently emerging newer Omicron subvariants which are presently causing a rise in cases in a few countries, such as China and others, and might lead to a feasible new wave of the pandemic with the surge in cases at the global level.
Qualitative and Quantitative Studies on Biopigment Producing Algal Regime from Marine Water Resources of Sundarban Region
Authors: Debnath Shrestha , Ghosh Dipankar
Published: March 2023

The current scientific studies have shown that extensive quantities of synthetic pigments are used worldwide in diverse industries. Synthetic pigments have shown enormous toxicity issues compared to natural colorants and dyes in current industrial usage. Diverse microbial communities, including fungi, bacteria, archaea, and yeast are current biopigment producers. However, the aforementioned biopigments are expensive, least efficient, and less eco-friendly to attain industrial sustainability. Thus, algae-based bio pigments are one of the best natural resources to meet today’s challenges. Algal pigments increase the product’s marketability and carry multiple therapeutic properties, including antioxidant, anti-inflammatory, and neuroprotective actions. These multidimensional qualities of algal pigments have piqued the interest of the food, pharmaceutical, cosmetic, and nutraceutical industries resulting in most potential implementation. Thus, a paradigm shift requires identifying potential algal communities having a higher biopigment-producing ability for future manufacturing and commercialization as a sustainable way forward. Hence, the current study has been designed for effective isolation and screening of algal isolates (i.e. DS1, DS2, DS3, DS4, DS5) from a different region of sundarban water resources concerning the investigation of algal pigments (i.e. chlorophyll-a, chlorophyll-b and carotenoid). In a nutshell, the current study shows that DS2 isolate produces a significant quantity of carotenoid (9.729 mg/g DCW), chlorophyll a (7.872 mg/g DCW), and chlorophyll b (7.176 mg/g DCW) amongst all isolates. Hence, the present study reveals that DS2 algal isolates might be a potential predecessor of biopigment production, having pivotal applications in food, pharmaceutical, cosmetic, and nutraceutical industries in the near future.
