Background: The co-existence of depression and hypertension increases the risk of cardiovascular disease mortality than hypertension alone. It is postulated that both these conditions share a common pathway, and understanding the natural history of their co-existence would be helpful for effective management. Objectives: to assess the prevalence of depression symptoms among hypertensive patients in Taif city, Saudi Arabia, and also to analyze various determinants related to their co-existence. Methods: Hypertensive patients attending a single tertiary care hospital in Taif city were recruited for our study after taking informed consent and ethical approval from the institution. A pretested proforma was used to collect data from the participants. Data were collected using three methods; the investigator recorded participants’ medical history and other clinical findings from hospital records in the first part. The participants themselves filled the second and third parts during their consultation in FM clinics. All data obtained were subjected to statistical analysis by an independent biostatistician. Results: The prevalence of depression among these hypertensive patients was 27.5%, and 2.5% had a severe form of depression. Middle-age was found to be an independent risk factor for the co-existence of hypertension and depression. Female hypertensive patients had a comparatively higher prevalence of depression (p=0.05). Even though depression was more seen among patients who smoked and didn’t do any physical activity, these were statistically not significant. Conclusion: Considering the high prevalence of depression among hypertensive patients, it is critical to developing screening programs and community education campaigns.

Published: September 2022

Purpose: The goal of this study was to determine the optimal method for treating gastric leaks in terms of resolution rate, complications, admission to the intensive care unit (ICU), conversion to other surgical techniques, and mortality. Methods: A retrospective analysis of patients treated at King Abdul-Aziz Specialist Hospital between 2017 and 2021 for post-LSG leaks. Age, gender, body mass index (BMI), preoperative comorbidities, leak rate, the interval between surgery and leak, the onset and site of leak, as well as the management lines and outcomes, were collected. Results: The leak rate following Laparoscopic Sleeve Gastrectomy (LSG) at our hospital was 0.53 percent, and there were no statistically significant differences in the demographic characteristics of patients with and without leaks. Despite the fact that 87.5 percent of patients were women, this was not statistically significant (P-value:0.09). The mean± SD interval between surgery and leak is 14 ±18.4, with early and acute leaks being the most common. Failure of first-line management, stent migration, and esophageal stricture were the most commoncomplications of leak management in our study. The mean length of hospital stays was 42.4 ±17.1 days, and the mortality rate was 12.5%. Conclusions: Leak after LSG is a drastic complication associated with substantial morbidity and mortality if diagnosis and treatment are delayed. Depending on the patient’s condition, location of the leak, and the time of diagnosis,; leak management may involve conservative, endoscopic, or surgical approaches. There are numerous measures that could be taken to reduce the leak incidence rate. Keywords: Bariatric surgery; Sleeve Gastrectomy; Leak; Treatment; Outcomes

Published: September 2022

Introduction: Documented articles have determined that viral illness during early pregnancy and several antiviral drugs are associated with an increased risk for neurodevelopmental congenital anomalies of the newborn. These include NTDs, the most common and severe malformations of spinal cord (spina bifida) or brain (anencephaly, encephalocele, hydrocephalus), which develop within 6 weeks of pregnancy with an incidence of one in 1000 neonates worldwide and they cause lifelong neurological complications. The aim of this study is to describe the clinical characteristics of simultaneous cases of COVID 19 in pregnant women with neural tube defects in their newborns. Patient and methods: This is descriptive study case series including cases of Neural Tube Defects when their mothers were affected with COVID-19 infection that was reported in Zahko Maternity hospital. Those in the labour unit were enrolled in this study and the cases was collected during the period 1st January 2020 and 1st January 2022. The information collected through direct interview with the mothers through questionnaire includes the information about the socio-demographic, obstetrical history and history of COVID 19 infection, severity presence of fever and type of medication received. Results: Regarding the general and obstetrical history of the patients, the current study revealed that the affected age group of mothers was as follows; 28 (41.2%) of them (26-30 years), and 15 (22.1) of them (> 35). Anemia and fever in the 1st trimester were found in 54 (79.4%) of them. Alcohol intake was reported in 2 (2.9%) of them, consanguinity in 19 (27.9%) of them, female newborns constituted 38 (55.9%), gestational diabetes mellitus in 1 (1.5%), diabetes mellitus in 6 (8.8%), and hypertension in 5 (7.4%). The drugs received during pregnancy, were as follows; antibiotics; all patients 100%; antihypertensive drugs received by 14 (20.6%), antipyretics 29 (42.6%), antacids 21 (30.9%), and antifungals 16 (23.5%). Conclusions: the COVID19 infection may be blamed as a cause of NTDs, and further research about the pathophysiology is needed.

Breast cancer is considered one of the major healthcare problems and one of the top biomedical research priorities among all biomedical research. Breast cancer is a common but extremely complex disease. The incidence of breast cancer becoming more aggressive is increasing, with around one million and seven hundred thousand new cases that get worse yearly, and this incidence is expected to increase significantly in the next 5–10 years. These rates are suggestive of the slow progress of this disease. Worldwide, Breast cancer is the most common cancer affecting women. The mortality rates for women who are already diagnosed with breast cancer have improved, but even then, the median survival in the metastatic stage is low, around 24 months. For the treatment, chemotherapy is the gold-standard approach for most cancer types and the modest improvement in both survival rates and toxicity reduction. Every newly diagnosed breast cancer should be presented at a multidisciplinary conference to ensure optimal management by all specialties involved. A careful history of a woman’s risk and symptoms and a thorough physical examination are important in the evaluation of breast problems and appropriately timed imaging and diagnostic studies are also important. Early detection of breast cancer at a stage when it is potentially curable and there is the possibility of saving a breast should be the goal of all health care professionals. Also, careful consideration should be given to the unique nature of each tumor and patient. This article aims to provide a brief introduction and the clinical picture of the disease, Etiology, Pathophysiology, Epidemiology, Nutrition, Prevention, and good practice management advice.

Headache is a common presenting symptom in Primary Care with a wide list of differential diagnoses and important red flag symptoms. It is vital in Primary Care to undertake a comprehensive history, careful examination and appropriate investigations when patients present with any of these symptoms. Clinicians should be mindful of the differential diagnoses and red flag symptoms in order to appropriately manage patients. It is also crucial to recognise when to get help from secondary care colleagues when faced with rare and complex cases that may need hospital admission for further investigations, management and monitoring. This case highlighted the importance of being aware of different, including rare, differentials when confronted with a common presenting symptom.

Authors: O. Bayma Lucas , A. Pereira Marconi
Published: September 2022

Climate prediction is a relevant activity for humanity and, for the success of the climate forecast, a good historical database is necessary. However, because of several factors, large historical data gaps are found at different meteorological stations, and studies to determine such missing weather values are still scarce. This work describes a study of a combination of several machine learning techniques to determine missing climatic values. This study extends our previous work, producing a computational framework, formed by three different methods: neural networks, regression bagged trees and random forest. Deep data analysis and a statistical study is conducted to compare these three methods. The study statistically demonstrated that the random forest technique was successful in obtaining missing climatic values for the state of Minas Gerais and can be widely used by the responsible agencies to improve their historical databases, consequently, their climate forecasts.

Authors: GÖK Mehmet Ali , KARATAY Emrah , ÇİFTÇİ Ali
Published: September 2022

Giriş: Günümüzde laparoskopik herni onarımları altın standart olma yolunda ilerlemektedir. Fakat laparoskopik total ektraperitoneal (TEP) inguinal herni onarımlarında disseksiyon balonun ve mesh sabitleyicinin getirdiği maliyet bu ameliyatların yapılmasında engel teşkil etmektedir. Bu çalışmanın amacı cerrahi deneyimle birlikte maliyetli malzemeler kullanmadan standart laparaskopik aletlerle bu ameliyatların yapılabilirliğini irdelemektir.

Yöntemler: Mart 2019-Nisan 2021 tarihleri arasında disseksiyon balonu ve mesh sabitleyici kullanılmadan laparoskopik TEP inguinal herni onarımı yapılan hastalar retrospektif olarak incelendi. Yaş,cinsiyet, intraoperatif ve postoperatif görülen komplikasyonlar, ameliyat süresi, hospitalizasyon süresi, günlük aktiviteye dönüş süresi, nüks parametreleri değerlendirildi.

Bulgular: Çalışma 86’sı sağ,76’sı sol, 44’ü çift taraflı olmak üzere 220 fıtık hastasına uygulanan TEP onarımı sonuçları üzerinden yapılmıştır. Ortalama yaş 52.55±18.02 yıldır. 186’sı erkek, 34’ü kadındır. Günlük aktiviteye dönüş sürelerinin ortalaması 3.98±1.68 gün, ameliyat süresinin ortalaması 39.55±11.32 dakikadır. Hastanede kalış süresinin ortalaması 0.78±0.16 gündür. Olguların 23 ünde intraoperatif komplikasyon, %5’inde seroma görülmüştür. 6. ay kontrolünde 3 hastada nüks görülmüştür.

Tartışma: Disseksiyon balonu ve mesh sabitleyici kullanılmadan yapılan laparoskopik TEP inguinal herni onarımı; literatürdeki diğer laporoskopik onarımlar ile kıyaslandığında komplikasyon oranlarının hastanede yatış ve günlük aktiviteye dönüş sürelerin benzer olması ve daha az maliyetli bir yöntem olmasından dolayı yaygın bir şekilde kullanılması önerilir.
Oldukça Nadir Görülen Toplum Kaynaklı Yara Yeri Enfeksiyonu Etkeni: Ralstonia pickettii
Authors: ALKAN BİLİK Özge , İNCE Fatma Meral , ÖZCAN Nida
Published: September 2022

Ralstonia pickettii (R. pickettii), Ralstonia cinsi içerisinde en sık rastlanılan tür olup non-fermenter, aerobik, Gram-negatif bir basildir. Fırsatçı bir patojen olan bakteri, hastane ortamından ve çevresel kaynaklardan bulaşabilir. R. pickettii immunkompetan bireylerde oral flora ve üst solunum yolu florasında kommensal olarak yaşayabilirken immun-kompromize kişilerde şiddetli enfeksiyonlara neden olabilmektedir. R. pickettii ile ilgili toplum kaynaklı rapor edilmiş az sayıda vaka bildirilmişken, genellikle hastane kaynaklı enfeksiyonlar rapor edilmiştir. Bu olguda ise toplum kökenli yara yeri enfeksiyonu olan erişkin bir hasta sunulmuştur.

Alt ekstremitede seropürülan akıntılı açık lezyon şikayeti ile başvuran 69 yaşında kadın hastanın laboratuvar parametrelerinden lökosit ve nötrofil sayısı ile sedimantasyon hızı değeri normalden yüksek olarak değerlendirildi. Yara kültürü alınan hastaya sefuroksim aksetil 2 x 500 mg/gün tablet tedavisi ampirik olarak başlandı. Numuneden hazırlanan Gram boyalı preparatta bol PMNL ve gram negatif basiller görüldü, Q-skoru Q3 olarak değerlendirildi. Kültürde üremiş olan koloniler Vitek 2 Compact (bioMerieux, Fransa) otomatize sistemi ile R. pickettii olarak tanımlandı. Mikroorganizmanın antibiyotik duyarlılık testi yine aynı otomatize sistem ile çalışıldı. Suş gentamisin, amikasin, piperasilin-tazobaktam, seftazidim, sefepim, siprofloksasin ve meropeneme standart dozda duyarlı iken trimetoprim-sulfametoksazole dirençliydi. 3 gün sonra poliklinik kontrolüne gelen hastanın yarasında iyileşme gözlendiği için mevcut antimikrobiyal tedavi devam ettirildi.

Bu olgu sunumunda, R. pickettii’nin toplumdan edinilmiş yara yeri enfeksiyonlarında karşımıza çıkabileceğine dikkat çekmek istedik. Genellikle kontaminant olarak kabul edilen bazı mikroorganizmaların enfeksiyon etkeni olabileceği akılda tutulmalı, toplum kökenli R.pickettii enfeksiyonu olasılığı göz ardı edilmemelidir.

Yapılan literatür taramasında ülkemizden bildirilmiş R. pickettii’ye bağlı toplum kaynaklı yara yeri enfeksiyonuna rastlanmadı. Dolayısı ile vakamız bildiğimiz kadarıyla, Türkiye’de bildirilen R. pickettii’ye bağlı ilk toplum kaynaklı yara yeri enfeksiyonu vakasıdır.

O objetivo da presente pesquisa é analisar as potencialidades das práticas de Justiça Restaurativa (JR) no processo de desenvolvimento de adolescentes que aceitaram participar dessas práticas. A pesquisa é de natureza qualitativa, descritiva e exploratória, composta de entrevista semiestruturada com dois adolescentes que participaram do Núcleo de JR (NJR). A pesquisa é um estudo multi caso. Para a análise dos dados, utilizou-se a análise de conteúdo. Os resultados indicam os desdobramentos da participação dos adolescentes no NJR, identificando o reconhecimento de si como apoio psicossocial para deter laços sociais e uma crítica ao modelo familiar. Com relação a aspectos vinculares dos adolescentes, estes conseguem identificar um rol deles envolto na busca por melhores condições de vida. Concernente à história de vida, os adolescentes sofrem efeitos do histórico de infância com ausência da figura paterna. Com relação às percepções dos adolescentes sobre sua participação junto ao NJR, estes tiveram, por parte da família, a reedição da violência por meio da desqualificação, mas também possibilidade de comunicação do sofrimento e experimentação de violência da segurança pública até chegar ao NJR. O conjunto de dados permite reflexões para a ampliação de práticas com adolescentes em conflito com a lei a partir do NJR.

100 Things (or so) a Ship Designer Needs to Know
Authors: Andrews David
Published: September 2022

It is probably invidious for anyone to propose some 100 things one should know about regarding an endeavour as diverse and complicated as ship design, however we are all familiar with little books in bookshops with “100 things and artist/architect etc. should know”, often accompanied by witty cartoons. Alas the latter has not yet to be achieved in this case – perhaps readers can provide their own illustrations to many of the items or more likely add their own.

The presenter/author of this listing has provided more conventional keynotes than this to several IMDC conferences. These have included “The Fascination of Ship Design” to the 2006 IMDC at Ann Arbor and “Is Marine Design now a Mature Discipline?” to the 2012 IMDC in Glasgow. As the originator of the IMDC State of Art Reports and since 2015 the International Chair of the IMDC series of conferences, the author has sought to bring together those issues that highlight the unique nature of Ship/Marine Design. Aside from ships being our largest mobile artefacts, the process by which they are conceived and brought to fruition is as varied as there are different vessels and consequently it is hard to pin down. In a recent substantial publication, the author produced an argument that the earliest stages of the design of complex vessels were indeed sophisticated, not least in the decision making that should underlie such a process. A summary of this argument and several other publications attempting to address many of the wider aspects of the process are presented as scene setting to the just over one hundred short statements that are listed as one way to convey to current and future practitioners of this challenging “art”, as summarising “what one ought to know”.

The listing is largely due to the author ‘though there are some from other practitioners of ship design that were too good to not include. The author has also found that there seems to be about seven broad categories that the statements seemed to address within the overall ”ship design” field. These are also presented for others to challenge.
An Integrated Simulation Workflow for Automated IMO Maneuverability Verification for Ship Design Based on Computational Fluid Dynamics
Authors: Mucha Philipp , Wheeler Miles
Published: September 2022

Understanding vessel maneuvering characteristics is important when designing ships.  Classification societies require vessels to pass pre-defined requirements for various maneuvers.  Within the design process, the use of high-fidelity simulation software can be used to help understand a vessel’s characteristics.  Particularly, computational fluid dynamics (CFD) approaches can be used to calculate the required hydrodynamic coefficients used in indirect maneuvering calculations. However, this typically requires dozens of simulations to be run with large amount of data processing as well. This paper focuses on an automated workflow that is setup to compute all the tests required to compute the hydrodynamic coefficients required for modelling vessel trajectories while also plotting various maneuvers and comparing the vessel’s performance against IMO regulations.  The workflow will determine whether or not the vessel will pass these regulations as well as determine all the required inputs to the maneuvering model.  The workflow will be implemented on a pod driven twin screw vessel and a practical example will be showcased while exploring different vessel configurations.
Design Novelty and Cost-Learning Dynamics in Offshore Fish Farming
Authors: Pettersen Sigurd Solheim
Published: September 2022

Fish farming in exposed and offshore waters are potential solutions to many biological and environmental problems currently facing marine aquaculture. Offshore fish farming will require development of larger, more complex marine structures and elaborate logistical support systems, including service vessels. While innovation in concept design for these systems are currently awarded by regulators, production costs that are substantially higher than for existing fish farming system represent a barrier to competitiveness. In this paper, we show that offshore fish farming can become competitive when global seafood demand grows, due to cost-learning dynamics previously documented in a wide range of industries. Using historical time series for production and costs, we find evidence of cost-learning curves in existing aquaculture, suggesting that unit capital expenditures decline at a given rate every time cumulative production capacity doubles. To investigate the potential for offshore fish farming, we develop a simple system dynamics model of key trends and important feedback mechanisms that drive investments in technologies for offshore fish farming. The analysis indicates that policies that reward novel concepts, like license waivers or subsidies, can trigger cost-learning dynamics and move offshore fish farming towards competitiveness. We also find that design novelty may limit the cost reductions that accrue from cost-learning effects. Following the quantitative results, we discuss how the forecasted cost-learning dynamics can be exploited under a regulatory regime that favors innovative concepts. Finally, we reflect on the opportunities an emerging offshore fish farming industry provides for ship design and for the re-use of vessels that have become stranded assets.
Innovative Maritime Design Education at NHL Stenden University of Applied Sciences

Published: September 2022

To educate ship designers of the future, NHL Stenden University of Applied Sciences aims to continuously innovate education  and update the curriculum, for example looking at digitally enabled education. In agreement with this Design Based Education (DBE) has been introduced, a new educational concept. In DBE, students work on projects that are provided by industry partners with core subjects providing the required information to successfully complete the projects.

Another endeavour is the introduction of the BSc minor “Advanced Engineering Tools for ShipX”, where X is shorthand for design and operation. This course is concentrated on engineering tools and methods that have emerged in the (construction) industry over the past decades. Because quite some tools are implemented in software, the minor starts with a programming course. However, the emphasis of the minor is not on programming, but on algorithms and algorithmic thinking. For programming languages come and go, while smart algorithms remain to serve us for centuries. Additionally in the BSc, gamification is used to educate an old trade: ship stability. Students experience the primary behaviour of a raft and the forces that act upon it in virtual reality. Afterwards the theory will have to be elaborated a bit more, and the students will have to practice with calculations, but first comes the understanding and only then the math.

The master Marine Shipping Innovation focusses on maritime professionals that want to expand their knowledge and learn to innovate. Many students have several years of industry experience and bring with them their expertise and knowledge. A trade they share with their teachers who also combine their teaching job with an additional job in industry. The master offers on demand education, where students can select from a wide range of subjects to further expand their knowledge.

At traditional universities, the focus lies on fundamental research, for example, design methods and design tools. Research at universities of applied science is more practical in nature. Engineering in general and the maritime industry specifically is very practical and the application of research is of high interest to the industry. For that reason the major Marine Technology has been selected to run a pilot for a post master applied research program called a Professional Doctorate (PD). The pilot starts in 2022 and currently the implementation of this program is in full swing.

In short, this article will discuss the education innovations in both the bachelor and master programs for Marine Technology. It will discuss how the changes are implemented and what the effect is on the education. Finally it will discuss the current steps that are taken to successfully introduce the Professional Doctorate.
Impact of Ship Coatings in Ice Covered Waters
Authors: Reimer Nils
Published: September 2022

Coatings for Ice-Going vessels as well as for Ice-Breaking vessels can significantly influence the resistance while sailing in ice-covered waters. Corresponding to the ice-breaking capability and the operational profile different coating variants can be applied. For vessels which are not or only partially sailing in ice covered waters anti fouling is an important part of the coating while vessels mainly operating in ice, the friction and abrasiveness are important factors. On the other hand yachts or other vessels requiring a smooth hull finish covering the steel structure are nowadays sailing in ice covered areas more frequently. These hulls are traditionally smoothened by filler while also new developments based on automatically applied foam are in the development phase.

Detailed knowledge of the service durability including the abrasiveness as well frictional coefficient can significantly influence the selection of the optimal paint for the targeted operational profile. To evaluate these effects and to gain a wider knowledge about ice and hull interaction test capabilities are extended during the research project “MegaYachtSchaum” in HSVA’s ice laboratory. The new developed test capabilities for frictional resistance and ice compression tests are presented and described in detail. First tests analyses using the automated test execution and evaluation setup  ” are presented. Findings generated by the newly implemented post processing tool will be discussed and conclusions about applicability of the newly developed test capabilities are given based on the example case. Furthermore the new test capabilities for ice friction and compression tests will be discussed based on their future assistance to select the most suitable hull coating for each trade.

Published: September 2022

Despite the continuous improvement of safety measures, maritime accidents remain a concern in our society. Thus, as the literature has shown, over the last ten years, the frequency of groundings and collisions accidents in the maritime domain has increased. An official accident investigation is conducted for each serious maritime accident, however, the level of detail changes from accident to accident, hence, the details about human contributors and organisational issues are not systematically analysed and reported in a way that makes future extraction of trends and comparisons possible. With the aim to better capture human and organisational factors, this paper proposes to utilise the Safety Human Incident & Error Learning Database (SHIELD) HF Taxonomy, which was developed in the context of the European Union SAFEMODE project, in line with the key components of NASA-HFACS, HERA, and Reason’s Swiss Cheese Model. Therefore, in this study, ten collision and ten grounding maritime accidents reported by various maritime agencies are analysed via the SHIELD HF Taxonomy to identify the main accident contributors, including design deficiencies. The paper further proposes a framework for how these results can be utilised to develop the design and operational measures to prevent collision and grounding accidents. The paper demonstrates the benefits of using HF taxonomy for identifying the underlying causes as well as developing mitigating design solutions.

Acompañamiento socioeducativo y resiliencia en jóvenes migrantes extutelados: una aproximación desde las oportunidades, los sueños y los apoyos
Authors: Herrera-Pastor David , Ruiz-Román Cristóbal , Bernedo Muñoz Isabel María , Crecente Dapena María
Published: September 2022

La falta de oportunidades que encuentran los jóvenes migrantes que viajan a España sin sus familias, choca con los sueños que les impulsan a arriesgar sus vidas cruzando desde África hacia Europa. Uno de los grandes retos que tiene hoy la acción socioeducativa que se desarrolla con este colectivo es promover sistemas de apoyo e inclusión que no los dejen en los márgenes de la sociedad. Este artículo se desprende de un proyecto europeo con jóvenes migrantes extutelados por el sistema de protección de menores que tenía como objetivo explorar los procesos de resiliencia y el acompañamiento socioeducativo experimen¬tados por dichos jóvenes. La metodología cualitativa combinaba varias técnicas de recogida de datos en las que se llevaron a cabo 32 Entrevistas para las Lifeline y 1 Grupo Focal con jóvenes migrantes, 1 DAFO y 1 Grupo Focal con profesionales de la acción socioeducativa y 4 Diarios Analíticos del alumnado universitario voluntario. Se presentan resultados en relación a tres grandes categorías: “Oportunidades”, “Sueños” y “Apoyos”, que se analizan poniendo de relieve el papel que adquieren tanto en las narrativas y desarrollo de los proyectos vitales de los jóvenes, como en la práctica de los profesionales de la acción socioeducativa. Todo ello se pone en discusión con la literatura más reciente para extraer algunas ideas valiosas para la práctica de la educación social en relación al tipo de acompañamiento educativo y a los procesos de resiliencia que estos jóvenes migrantes esperan poder desarrollar en sus proyectos migratorios.
Livinglabs como modelos de innovación abierta. Análisis a partir del concepto de extitución
Authors: Aceros Juan C. , Martín García Antonio Víctor , Gutiérrez Pérez Bárbara Mariana
Published: September 2022

La innovación abierta es una forma de organizar los procesos de innovación ydesarrollo (I+D) que se ha popularizado recientemente. La distancia que el modelo de la innovación abierta pretende establecer con respecto a la innovación cerrada es un lugar comúnen gran cantidad de publicaciones. Sin embargo, diversos trabajos la ponen en duda. En este artículo proponemos una lectura crítica de la innovación abierta a la luz del concepto de “extitución”. Con ayuda de esta noción describimos la forma como determinadas organizacionesdefinen su “ambiente de innovación” y los “actores externos” a los que pretenden articular a los procesos de I+D. Los casos de estudio son los laboratorios vivos en España que se dedican al sector de la salud y el bienestar. El material se recolectó utilizando métodos virtuales yse analizó utilizando un enfoque inspirado en la Sociología de la Traducción. Los resultados dan cuenta de una persistente invitación a establecer relaciones fuertes con el laboratorio, a través de un conjunto de esfuerzos de problematización, interesamiento y enrolamiento,mediante las cuales estos se relacionan con su exterioridad. A partir de estos resultados, se discute el carácter extitucional de los laboratorios vivos en el contexto de la gerontecnologíaeducativa.

Pain and asthenia are symptoms of difficult control in cancer patients and greatly determine their quality of life. Conventional ozone therapy is used successfully in the symptomatic control of patients with cancer. We believe that the administration of ozone at high doses through IPO3 could provide an additional benefit in the control of refractory symptoms in patients with cancer.
We present below a cancer patient with very deteriorated quality of life, successfully treated with IPO3.
The patient is a 48-year-old woman with a history of breast cancer who has a disseminated metastatic recurrence that affects bones, skull, liver, lung and peritoneum, with symptomatology refractory to symptomatic medication. Her quality of life was limited by severe asthenia (which kept her bedridden for more than two months) and pain refractory to symptomatic treatment with opiates and corticosteroids.
The patient was treated with a cycle of rectal ozone therapy, consisting of a conditioning cycle with 15 sessions of oxygen / ozone rectally, followed by placement of a peritoneal catheter to subsequently perform five IPO3 sessions.
At the end of the treatment, all the symptoms of the patient were resolved completely, allowing the withdrawal of all the analgesic medication, returning the patient to a normal life. There were no side effects, and the beneficial effects of this IPO3 cycle were maintained for more than two months. The analysis showed diminution of the tumor and inflammatory markers during the treatment.
Ozone therapy at high doses should be considered in cancer patients with severe symptoms and refractory to conventional treatment.

SARS-CoV-2 is an RNA virus that can cause pneumonia leading to acute respiratory distress syndrome and pulmonary fibrosis (PF). Lung damage caused by COVID-19 can cause severe permanent respiratory failure. Ozone therapy (OT) is used as a complementary treatment during the COVID-19 pandemic. PF, which is one of the interstitial lung diseases, is also radiologically identified in COVID-19 patients. In this case report, regression and healing on thorax CT findings are presented for a severe COVID-19 pneumonia-related intensive care unit patient who was diagnosed with PF on the post-COVID ward and treated with OT on the ward and even after discharge from hospital.

Bio-oxidative therapies accelerate oxygen metabolism, stimulate the antioxidant defense system, having analgesic, anti-inflammatory and immunomodulatory properties, among others.

A quasi-experimental study was carried out with the objective of knowing the clinical behavior of osteoporosis during ozone treatment at the Provincial Center for retinitis pigmentosa, Camagüey (Cuba) from January - June 2006.

The universe: 53 patients, 50 cases that met the inclusion criteria: patients with osteoporosis, those who agreed to participate in the study with prior informed consent and who decided to join the study by suspending or eliminating previously used therapies.
Ozone was rectally applied, 20 sessions in 2 cycles per year.

It was registered the following variables: age groups and sex, evaluation of signs and symptoms, distribution according to occupation, clinical evolution according to cycles, variation of drug treatment and social and economic impact.

The predominant ages: 31-40 and +41 years with 16 (32%) and 21 (42%) respectively, the main symptom pain 50 (100%), occupation: workers: 42 (84%). After 20 sessions of ozone, the results were: improved 38 (76%), 50 (100%) decreased the dose of medications.

Patients were incorporated into society in less time, improving their bio-psycho-social state with a cost five times lower than the standard treatment.
The Impact of the Age of the Vehicle Fleet on Traffic Safety - Vehicle as the Third Pillar of Traffic Safety
Authors: Deretić Nemanja , Stanimirović Dragan
Published: September 2022

Traffic accidents are, today, accepted as a global problem and activities are being undertaken to adapt and transfer successful practices from the most developed countries to underdeveloped and developing countries. The impact of a road transport system is so significant that its safety or lack of safety affects a wide range of social needs. Road safety or mobility without risk of death or injury affects health, poverty, equality, the environment, employment, education, gender equality and the sustainability of communities. Many nations around the world have improved the effect of pillar interventions by applying them selectively and strategically in accordance with the principles of the safe system approach. The safe system approach addresses problems closer to their root cause and on a broader level than conventional methods. The five pillars of road safety identified in the Global Plan for the Decade of Action 2011-2020 include a set of evidence-based interventions that can measurably improve road safety. Preparation and adoption of strategic documents - a traffic safety system development policy and strategy is a great way to demonstrate traffic safety management. The most important common denominator for all successful traffic safety practices is science-based strategic traffic safety management, which has clear, honest and publicly expressed political support. The paper presents the analysis of the third pillar „safer vehicles“ and its influence on the approach of the safe system from different aspects.
New Phase of Motor Vehicle Development

Development of motor vehicles has gone through several technological phases and today we are definitely in a new era that is primarily related to steering autonomy and vehicle propulsion systems. Although electric vehicles have become an absolute priority in some countries, their global expansion is happening and it is to be expected that they will become a near future in these regions as well. Today, special attention is drawn to advances in the development of autonomous driving systems, which will cause many changes in design, regulations and the environment. For the coming wave of change, we need to be adequately prepared and take part in global processes. In addition, it should be noted that the futuristic versions of vehicles capable of moving in multiple environments, on land, on or in water and in the air, are being widely promoted, and the EU is introducing mandatory application of some active and passive safety systems.

Published: September 2022

The paper describes the importance and the role of the subsystem of flexible transportation of passengers (paratransit) in the system of a public city transportation of passengers (PCTP). It is a system with several forms and can be defined by several parameters, but in large number of cities in the world it gains more importance in the PCTP system. This paper describes this system with its characteristics, i.e. its positive characteristics that lead to increased combined mobility of population in cities in the PCTP system, i.e. to decreased use of passenger cars.

There is a lack of studies evaluating frailty and physical activity in people aged 100 years or older. This review aimed to synthesize the evidence on frailty and physical activity in centenarians. A systematic review was conducted according to the PRISMA guidelines. We searched the PubMed, CINAHL, SCOPUS, Web of Science, and Lilacs databases for articles published until 18 June 2020. This review was registered with PROSPERO (CRD42020162913). Five studies were included in this review according to the eligibility and exclusion criteria. In summary, the reviewed studies show that centenarians are fragile and that frailty increases with age; however, women are frailer than men. The most common frailty criteria were low physical activity level(78% to 72.5%), muscle weakness (84.2% to 66%), and slow walking speed (77.6% to 48.4%). Most centenarians perform less exercise than younger older adults, have a low physical activity level, live in nursing homes, and exhibit functional disability. Regarding the methodological quality of the studies, one article was classified as regular and the other four as poor. Frailty and a low physical activity level arecommon in centenarians. Experimental studies with better methodological quality are necessary to better understand the causal relationship between variables.

Introduction: Rheumatoid arthritis (RA) is classified as an autoimmune, chronic disease affecting diarthrodial joints and periarticular structures. Objective: To evaluate whether low-intensity laser treatment (LLLT) and/or exercise reduce the deleterious effects of tissue in a rheumatoid arthritis model. Methods: 128 rats were divided into two inflammatory periods: acute (7 days) and chronic (28 days) and subdivided into control, injury and treatment. The protocol with Freund's Complete Adjuvant was used in two inoculations, one intradermal and one intraarticular in the tibiofemoral joint, the control animals received saline solution. For treatment, LLLT 660 nm, 5 J/cm² was used in the sensitized joint and climbing exercise in stairways with an overload of 100 grams. After the experimental period, the animals were euthanized and the joints were prepared for morphometric analysis of the total thickness, superficial, deep, and cellular density of the articular cartilage. Generalized Linear Models with Sidak post-test were chosen. Results: The control group was found to be different from the lesion group with greater joint cartilage thickness, and the animals treated with exercise alone increased the joint cartilage compared to the control group. Conclusion: The animals treated with laser association and exercise showed improvement in the morphometric aspects of the articular cartilage.
