Delivering Behaviour Change Techniques via Short Text Messages to Promote Active Travel
Authors: Doğru Onur Cem
Published: March 2022

Active travel has many benefits for both individuals and societies. While the number of interventions aiming to promote active travel increases, it is usually not easy to deliver those interventions, identify ‘active components’ of them, and/or replicate them. The current paper reports two studies testing interventions that used SMS messages to deliver behaviour change techniques (BCTs) based on the Control Theory (i.e., goal-setting (behaviour), action planning, self-monitoring of behaviour). Study 1 sought to increase the use of a bike share scheme. Participants were randomly assigned to one of three experimental groups that received messages for three BCTs (n = 26), one BCT (n = 29), or no BCTs (n = 40) and were followed up one month later. The effect of intervention on bike use was significant when two intervention groups were combined and compared to the control group. Study 2 tested an intervention to decrease car use. Participants were randomly allocated to one of two experimental groups that receive three BCTs (n = 29) versus no BCTs (n = 32). The effect of the intervention on car use was marginally significant. The results of the two studies suggest that interventions delivering BCTs via SMS message may be used to promote active travel, although both studies were underpowered. Given the relative ease and low cost of delivering psychosocial interventions via SMS messages, the potential public health impact at a population level is, nonetheless, likely to be important.

Published: March 2022

Detecting the stroke etiology in young patients can be challenging. Among others, determining causality between ischemic stroke and patent foramen ovale (PFO) remains a complicated task for stroke neurologists, given the relatively high prevalence of PFOs. Thorough diagnostic workup to identify incidental vascular risk factors and rare embolic sources is crucial to avoid premature PFO closure suggesting successful secondary stroke prevention. In this paper, we report on a 38-year-old patient with recurrent vertebrobasilar territory, especially right posterior inferior cerebellar artery (PICA) territory strokes. After the initial suspicion of a left vertebral artery (VA) dissection was not confirmed by ultrasound and magnetic resonance imaging (MRI) and other major risk factors were excluded, a PFO was detected and closed. Successful PFO closure was confirmed by transesophageal echocardiography, yet recurrent transient-ischemic attacks and vertebrobasilar strokes, especially during nighttime and in the early morning, occurred despite various antiplatelet and antithrombotic regimes and a persistent right-to-left shunt was detected by bubble transcranial Doppler. Finally, MRI after another vertebrobasilar infarction detected a transient left VA occlusion that finally led to the diagnosis of a left VA pseudoaneurysm from an incident emboligenic dissection in the atlas segment. This pseudoaneurysm together with an anatomical variant of the right PICA originating with the right anterior inferior cerebellar artery from the basilar artery finally explained the recurrent ischemic events of the patient. After successful treatment with coil occlusion, the patient suffered no further stroke and recovered completely. In summary, stroke in the young remains a diagnostic challenge. The incidental finding of a PFO should not deter from thorough stroke workup and the follow-up of these patients including PFO closure verification should be performed under the guidance of vascular neurologists.

Published: March 2022

BACKGROUND:

There is emerging evidence that COVID-19 can trigger thrombosis because of a hypercoagulable state, including large-vessel occlusion ischemic strokes. Bihemispheric ischemic stroke is uncommon and is thought to indicate an embolic source. Here, we examine the findings and outcomes of patients with bihemispheric stroke in the setting of COVID-19.

METHODS:

We performed a retrospective cohort study at a quaternary academic medical center between March 1, 2020, and April 30, 2020. We identified all patients with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection who presented with simultaneous bihemispheric ischemic strokes.

RESULTS:

Of 637 COVID-19 admissions during the 2-month period, 13 had a diagnosis of acute ischemic stroke, including 5 who developed bihemispheric cerebral infarction. Three of those 5 (60%) were female, median age was 54 (range 41–67), and all five were being managed for severe COVID-19-related pneumonia complicated by acute kidney injury and liver failure before the diagnosis of cerebral infarction was established. Five presented with elevated ferritin, lactate dehydrogenase, and interleukin-6 (IL-6) levels, and four had lymphopenia and elevated D-dimer levels. All patients underwent neuroimaging with computed tomography for persistent depressed mentation, with or without a focal neurologic deficit, demonstrating multifocal ischemic strokes with bihemispheric involvement. Outcome was poor in all patients: two were discharged to a rehabilitation facility with moderate-to-severe disability and three (60%) patients died.

CONCLUSIONS:

Stroke is implicated in SARS-CoV-2 infection. Although causality cannot be established, we present the imaging and clinical findings of patients with COVID-19 and simultaneous bihemispheric ischemic strokes. Multifocal ischemic strokes with bihemispheric involvement should be considered in COVID-19 patients with severe infection and poor neurologic status and may be associated with poor outcomes.
Ischemic stroke due to sporadic and genetic pulmonary arteriovenous malformations
Authors: Tagliapietra Matteo , Turri Giulia , Bortolotti Federica , Mansueto Giancarlo , Monaco Salvatore
Published: March 2022

Pulmonary arteriovenous malformations (PAVMs) encompass congenital and genetic vascular anomalies characterized by complex interlacing of arteries and veins connected by fistulas, which allow rapid and continuous extracardiac right-to-left shunting (RLS). Presenting neurologic manifestations of PAVM include brain abscess and stroke, as the consequence of paradoxical embolism. Although rare, PAVM represents an overlooked cause of cryptogenic ischemic stroke in young adults, being misdiagnosed as patent foramen ovale and a preventable trigger of silent cerebral ischemic changes. In the emergency clinical setting, the recommended ischemic stroke workup in patients with RLS should include the influence of postural changes and the effect of Valsalva maneuver on the entity of the RLS on contrast-enhanced transcranial color Doppler ultrasound and the delay in the right inferior pulmonary vein and left heart opacification on contrast-enhanced transthoracic echocardiography. This is in addition to the evaluation of chest X-rays or thoracic computed tomography. We here describe two patients with ischemic stroke due to sporadic and genetic PAVM-associated paradoxical embolism.
Neurological deterioration and computed tomography perfusion changes with increased time to peak in lacunar stroke
Authors: Farooqui Amreen , Albayram Mehmet S , Reddy Varalakshmi Ballur Narayana , Nagaraja Nandakumar
Published: March 2022

OBJECTIVES:

Lacunar strokes can have fluctuations and progression in the acute period leading to poor outcomes. Our study sought to evaluate if, in lacunar strokes, neurological deterioration (ND) was associated with blood pressure (BP) variations, stroke size, or increased time to peak (TTP) on admission computed tomography perfusion (CTP).

METHODS:

Patients with lacunar stroke who had magnetic resonance imaging and CTP performed were enrolled in the study. ND was defined as ≥1-point worsening on a modified National Institutes of Health Stroke Scale (NIHSS) score or the Medical Research Council scale compared to baseline assessment. The difference in BP between the day of admission and the day of ND was calculated. Multivariate logistic regression analysis, adjusted for pertinent clinical and imaging covariates, was performed to determine predictors of ND.

RESULTS:

Among 409 patients screened, 49 were eligible for the study. There was no difference in age, gender, race, medical history, admission BP, and the modified NIHSS score between patients with and without ND. In unadjusted analysis, patients with ND tended to have increased TTP in the stroke area compared to the control (12 [63%] vs. 11 [37%], P = 0.07). On multivariate analysis adjusted for covariates, presence of an increased TTP on CTP was a predictor of ND (odds ratio [95% confidence interval] = 4.80 [1.15–20.10], P = 0.03).

CONCLUSION:

The presence of an increased TTP on CTP corresponding to the stroke lesion on diffusion-weighted imaging is a predictor of ND in patients with lacunar stroke. Larger studies are needed to confirm our findings.

Published: March 2022

Patients with left ventricular assist devices (LVADs) provide a unique challenge with regard to the management of subdural hematomas (SDH), due to preexisting comorbidities and induced coagulopathy. We report on the case of a 63-year-old female with a preexisting LVAD who developed an acute on chronic SDH with 15 mm of midline shift. She was successfully treated with middle meningeal artery (MMA) embolization and placement of a bedside subdural evacuating port system without hematoma recurrence at 1-year follow-up. Both operative and nonoperative management of SDHs in patients with LVAD is associated with high risk of mortality and morbidity. Chronic SDHs in this patient population can be successfully managed with a minimally invasive approach that includes MMA embolization and bedside subdural drain placement.

Published: March 2022

The effects of commercial formulations of Viburnum opulus and Equisetum arvense extract on anti-cytotoxicity and anti-genotoxicity were evaluated at the root tip of Allium cepa L. Distilled water (negative control), dimethyl sulfoxide (DMSO), ethyl methane sulfonate (EMS, positive control), 5% and 10% doses of V. opulus and E. arvense extracts were applied for 24 and 48 hours. Cytotoxicity and genotoxicity were evaluated by calculating %mitotic index and %chromosomal aberration index, respectively. When the 24h and 48h application of V. opulus and E. arvense extracts were compared with distilled water and DMSO applications; It was determined that these extracts increased the mitotic index and decreased the chromosomal aberration index. It was found that the mitotic index increased and the chromosomal aberration index decreased depending on the increase in the extract dose for 24h and 48h except for V. opulus. Chromosomal aberrations such as C-mitosis, polar shifting, and laggard chromosome were observed in A. cepa root tips meristematic cells by microscope. As a result of this research, it can be stated that commercial formulations of V. opulus and E. arvense extracts are anti-cytotoxic and anti-genotoxic in A. cepa root tip cells when compared with distilled water, DMSO and EMS groups.

Today, in factories, production is spread into a wide area and became complicated. Complicated production requires a better monitoring and control system to improve efficiency. For this purpose, SCADA systems are used. SCADA systems allow industries to monitor, control and access to real-time data and data logging. Nowadays, all large-scale industries have SCADA systems. The cost of the SCADA system makes it unreachable for small and medium-size industries but a SCADA system that is designed by using C# programming language would be cheaper and could perform the same. In this study, a SCADA system has been developed to monitor and control the smart model factory system in AFSUAM. SCADA interface is created by using C# programming language and the communication between PLC and the SCADA is set by using Mitsubishi MX Component tool. With the developed SCADA system, the process of a product entering the factory as raw material, going through several processes and becoming a product from the supply chain to the distributor has been modeled on a sample marble factory model, and a graphical user interface has been created considering the purposes such as real-time monitoring, controlling, data logging and preventing errors in the context of this model.

In recent years, according to the requirements of wireless applications, multiband and low profile patch antennas are desired. In this study, a simple rectangular patch triband microstrip antenna is developed to use for Bluetooth/WiFi applications. The antenna is in the form of rectangular slots with different lengths loaded on the rectangular patch with reduced ground size. FR-4 substrate with 1.6 mm thickness is used as substrate material and annealed copper is used as ground and patch materials. The designed antenna is simulated using CST MWS software program. Microstrip line feeding technique with discrete port is used to feed the antenna. According to the results, S11 parameters of three resonant frequencies can be given as  -15.08 dB, -11.88 dB and -24.03 dB at 2.39 GHz, 3.07 GHz and 4.92 GHz respectively. Gain values of the resonance frequencies can be given as follows, 2.25 dBi, 3.76 dBi and 1.92 dBi at 2.39 GHz, 3.07 GHz and 4.92 GHz respectively. Proposed antenna bandwidth can be given as, 197.5 MHz (2.29 GHz – 2.49 GHz) at 2.39 GHz, 116.1 MHz (3.01 GHz – 3.13 GHz) at 3.07 GHz and 266.2 MHz (4.79 GHz – 5.06 GHz) at 4.92 GHz, respectively. Since the designed antenna can work at 2.4 GHz and 5 GHz frequency bands with 2.24 dBi and 2.34 dBi, respectively, IEEE 802.11ac/b/g standards are supported by the antenna. So the proposed antenna can be used for Bluetooth and 2.4 GHz/5GHz WiFi applications.

Quality education can be traced back to the level of early childhood education as assessed by the participation rate in Early Childhood Education (ECE). The ECE participation rate is determined by three indicators: the School Participation Rate (SPR), the Gross Enrollment  Rate (GER), and the Pure Participation Rate (PPR). However, there are still gaps in the national ECE participation rate, children who have not earned ECE services, and some villages that do not have ECE institutions. Although the Ministry of Education and Culture has established guidelines for one village one ECE. The purpose of this research is to provide an overview of ECE participation rates in Riau Province and to explain what factors influence them. This study used descriptive analysis. Secondary data were obtained from the Central Bureau of Statistics, the Ministry of Education and Culture, and the Ministry of National Development Planning/National Development Planning Agency. The results show that the ECE participation rate, in general, has been fluctuating, especially in the last five years, and that the GER of children attending ECE in Riau province is still lower than the national rate, while the PPR in rural areas is higher than the NER in urban areas. According to PER by gender, girls who attend ECE on time contribute more than boys. Those are influenced by the fact that ECE institutions are not recorded in the education database, and there are social trends that lead parents to prefer homeschooling over ECE institutions, particularly with the impact of the COVID-19.
Los orígenes del surf en Hawai. ¿La mejor campaña de marketing turístico de la historia? (The origins of surfing in Hawaii. The best tourism marketing campaign in history?)
Authors: Santos Diego
Published: March 2022

El surf es una práctica que cada vez acapara más relevancia en nuestra sociedad. Esta práctica tiene en multitud de comunidades implicaciones socioeconómicas que son cada vez más importantes ya que el aumento de practicantes ha conllevado también un aumento de empresas que tratan de prestarles servicios. Muestra de su creciente relevancia social es que cada vez son más los medios de comunicación generalista que dan cobertura a noticias vinculadas con el deslizamiento sobre las olas, en especial, seguramente por su estética radical, a los hitos alcanzados por los surfistas que cabalgan olas gigantes. El crecimiento de practicantes de surf se vincula con la representación fenomenológica que tiene de muchos de los valores aspiracionales de la sociedad contemporánea como la libertad, la vida en la naturaleza o el hedonismo. Valores asociados al espíritu Aloha, al cual se vinculan los orígenes del surf. Sin embargo, los hallazgos realizados tras una revisión bibliográfica de varios de los principales textos bibliográficos sobre la historia y cultura surf, nos llevan a la conclusión de que parece evidente la existencia de un interés en ofrecer una visión romántica de los orígenes del surf. El nacimiento del surf, aunque muchos historiadores pretendan negarlo, es una total incógnita, sin embargo, vincularlo con raíces polinesias ha servido para moldear la imagen paradisíaca socialmente construida que el marketing ha logrado perpetuar. 
Abstract. Surfing is a practice that is becoming increasingly important in our society. This practice has socioeconomic implications in many communities that are increasingly important since the increase in practitioners has also led to an increase in companies that try to provide them with services. An example of its growing social relevance is that more and more general media are covering news related to surfing the waves, especially, surely due to its radical aesthetics, the milestones reached by surfers riding giant waves. The growth of surfers is linked to the phenomenological representation that they have of many of the aspirational values of contemporary society such as freedom, life in nature or hedonism. Values associated with the Aloha spirit, to which the origins of surfing are linked. However, the findings made after a bibliographical review of several of the main bibliographical texts on the history and culture of surfing, lead us to the conclusion that the existence of an interest in offering a romantic vision of the origins of surfing seems evident. The birth of surfing, although many historians try to deny it, is a total unknown, however, linking it with Polynesian roots has served to shape the socially constructed paradisiacal image that marketing has managed to perpetuate.

Published: March 2022

The aim of this study was to examine the possible differences on anthropometrics and strength performance between young basketball players with different maturity status. Thirty-one male players (12-15 years) participated in the study. Their maturity status was estimated by the years from/to their peak height velocity (PHV) and players were categorized as pre-, mid- or post-PHV. The analysis of variance showed significant differences in players’ body weight and height according to their maturity group. Players’ strength performance (1RM, SJ and CMJ) was significantly different between the maturity groups. Pearson’s correlation analysis showed a correlation between the PHV and the players’ weight, height and performance in 1RM (r = 0.74 – 0.80; p < .001) but not with the performance in the SJ and the CMJ (r = 0.19; p = .295 and r = 0.35; p = .055, respectively). In addition, the linear regression analysis showed that the PHV predicted the players’ weight, height and performance in 1RM (β = 0.74-0.80; p < .001; R2 = 0.55-0.65). The results of this study showed anthropometric and strength performance advantages for young basketball players with an advanced maturity status. These findings may have an impact on talent identification, selection and long-term development processes.
Resumen. El objetivo de este estudio fue examinar las posibles diferencias antropométricas y de rendimiento de fuerza entre jóvenes jugadores de baloncesto con diferente estado madurativo. Treinta y un jóvenes (12-15 años) participaron en el estudio. Su estado madurativo fue estimado con los años desde/hasta su pico de velocidad de crecimiento (PHV) y se les categorizó como pre-, mid- o post-PHV. Los análisis de la varianza mostraron diferencias significativas en el peso y la altura de los jugadores de acuerdo con su grupo de maduración. El rendimiento en fuerza de los jugadores (1RM, SJ y CMJ) fue significativamente distinto entre los grupos madurativos. El análisis de correlación de Pearson mostró correlación entre el PHV y el peso, la altura y el rendimiento en fuerza de los jugadores en el 1RM (r = 0.74 – 0.80; p < .001), pero no en el SJ ni el CMJ (r = 0.19; p = .295 and r = 0.35; p = .055, respectivamente). Además, el análisis de regresión lineal mostró que el PHV predijo el peso, la altura y la fuerza de los jugadores en el 1RM (β = 0.74-0.80; p < .001; R2 = 0.55-0.65). Los resultados de este estudio muestran ventajas antropométricas y de rendimiento en tareas de fuerza para los jóvenes jugadores de baloncesto con estado madurativo avanzado. Estos hallazgos pueden ser relevantes en los procesos de identificación, selección y desarrollo a largo plazo.

Published: March 2022

Introduction
The COVID-19 virus has already caused a pandemic and needs no fresh introduction. Many studies in western literature have described the prevalence of anosmia and ageusia as symptoms of COVID-19. However, to our knowledge, there is no study describing the trend of new onset ageusia amongst covid positive patients in the Indian population. The objective of this study is to analyze the trend of new onset ageusia in COVID-19 affected individuals in the Indian population.
Materials and Methods
This is a retrospective observational study conducted in a treatment facility set up in Eastern part of India. The data was collected from Sep 2020 to Dec 2020. The study included 422 patients who were laboratory confirmed COVID-19 positive cases. Clinical data was extracted from the medical records of the patients. All the patients were treated as inpatients. The data was collected by Critical care specialist and Physician. All patients were classified as asymptomatic and symptomatic. The presence or absence of new onset ageusia was documented and statistically analyzed.
Results
Of 422 cases studied, 401 (95.0%) were male and 21 (5.0%) were female with the mean age of 37.9 ± 8.3 years. 147 (34.8%) were symptomatic and 275 (65.2%) were asymptomatic with 18 % (76/422) patients having ageusia in the study population.
Conclusion
The prevalence of ageusia amongst covid positive patients in Indian population is lesser as compared to reports in the western literature. The cause of this difference in prevalence of ageusia in different ethnicities is unknown. Apparently healthy individuals with new onset ageusia should be considered as asymptomatic covid carriers and should be treated accordingly.

Published: March 2022

Introduction
The shape of the nose is a signature indicating the ethnicity, age, and sex of the person. Our aim is to map the range of various anthropometric parameters of nose in South Indians.
Materials and Methods
This study includes measurement and statistical analysis of different parameters of nose among 61 South Indian medical students (34 females;27 males) using digital Vernier calipers.
Results
The means of various parameters were- 1) Nasal Breadth -2.9cm (males) and 2.5 cm (females). 2) Nasal height-5 cm (males) and 4.9cm (females). 3) The nasofacial angle-37.9 degree (males) and 36.7 degree (females). 4) The nasolabial angle 115.2 degree (males) and 116.5 degree (females). 5) The nasofrontal angle 127.1 degree (males) and 134.7 degree (females). 6) The most common type of nose is leptorrhine in both males and females.
Conclusion
All the measurements can be used for evaluation of nasal deformity, treatment planning and post-surgical evaluation of the correction achieved during rhinoplasty.

Authors: Lakshanadeve V.M. , Vikram Raj Mohanam T.C. , Savery Nishanth , Kurien Mary
Published: March 2022

Introduction
Postoperative hearing outcome after tympanomastoid surgery may sometimes be disappointing. This study aims to identify the factors influencing hearing outcome in squamous type of chronic otitis media (COM).
Materials and Methods
Prospective descriptive study on consecutive patients undergoing tympano-mastoidectomy for squamous COM.
Results
Analysis of 40 ears revealed that 10% had discharge less than one year with majority (75%) having more than three years. Pars flaccida and postero-superior pars tensa retraction pockets were most common findings with frank cholesteatoma only in 10%. Though mean preoperative pure tone average was significantly better (p=0.004) in those with ear discharge less than one year, 50% required type IV tympanoplasty, irrespective of duration of discharge. Type IV tympanoplasty revealed significant worsening of hearing (p=0.05), unlike type I-III where intact stapes suprastructure showed a significant postoperative improvement (p = 0.036). Successful graft uptake with discharge free ear was noted in 97.5% by 12 weeks.
Conclusion
Majority of our patients availed otolaryngologist opinion after more than three years of onset of discharge. Significant ossicular erosion occurs early in the disease. Preoperative better audiogram is not a predictor of ossicular status. Lack of significant symptoms and subtle clinical finding in the tympanic membrane, overlooked by the patient as well as the primary health care provider are confounding factors for early referral and surgical intervention by otolaryngologist. There appears to be a considerable delay for the common person in reaching the services of otolaryngologist; a relevant issue which need to be addressed at a national level to reduce the burden of the disease.

Authors: D C Sathyaki , P A Nalina
Published: March 2022

Introduction
Keloids are well known for recurrence. There is no standardized regimen for the treatment of keloids. Many different treatment modalities such as surgical excision, intralesional corticosteroids, radiotherapy, and pressure earrings have been used for keloids. Surgical excision alone may result in recurrence rate of 40%-100%.  This study was conducted to evaluate the efficacy of triamcinolone in preventing recurrence of Keloid.
Materials and Methods
Of the 40 patients who underwent excision of keloid at a tertiary care centre, surgery alone was performed in 20 patients and surgery with post operative intra-lesional triamcinolone injection was given weekly interval for 6 weeks in another 20 patients. Patients were followed up for the period of 2 years
 Results
Recurrence was found in 5 patients who underwent excision alone and there was no recurrence among patients who received post operative intra-lesional triamcinolone.
Conclusion
Multi-modality treatment is better to prevent recurrence of Keloid.

Introduction
Oral Submucous Fibrosis (OSMF) in severe cases involves palatal and paratubal muscles of Eustachian tube leading to Eustachian tube dysfunction and hearing disabilities. This study aims to evaluate to evaluate hearing status and Eustachian tube function in patients of Oral Submucous Fibrosis and to correlate them with various groups of the disease.
Materials and Methods
A Cross Sectional study was carried out in a Tertiary Care Hospital on diagnosed patients of OSMF. Patients with hearing loss due to other middle ear pathologies or previous ear surgeries were excluded. Patients were classified into various Groups depending on the severityof the disease. They were subjected to Pure Tone Audiometry and Impedance Audiometry. Results obtained were statistically analysed.
Results
A total of 121 patients (242 ears) were included in the study. On Pure Tone Audiometry, minimal hearing loss was found in 20(8.26%) ears while mild and moderate hearing loss was seen in 26(10.74%) and 28(11.58%) ears respectively. On tympanometry, Type B and Type C tympanograms(abnormal) were seen in 36(14.88) and 26(10.74%) ears, respectively. On Eustachian Tube Function Test, out of 242 ears, 67 ears (27.68%) showed Eustachian tube dysfunction. On using Pearson’s chi square test, significant association was found between degree of hearing loss, type of tympanograms and eustachian tube function with various groups of OSMF (p value < 0.05).
Conclusion
OSMF may affect hearing efficiency and Eustachian tube function as the disease progresses.

Framework Towards Decentralized Autonomous Space
Authors:   ETH Zurich, Wang Hongyang
Published: March 2022

In this presentation, we introduce the concept of Decentralized Autonomous Space, where agents of human and self-owning machines come together and are governed through a blockchain-enabled decentralized system. The research focuses on the governance aspects of such a space, meaning the decision-making and value allocation processes. Then the proof-of-concept prototype is described. The prototype is designed to be a single-person, soler-powered, and self-owning meditation space. The technical feasibility of the space is established through a preliminary electronic system that is connected and autonomously broadcast to the blockchain. Users can interact with the space by connecting crypto wallets. Ultimately, this research explores the possibility of the coordination of mixed-agent communities and the possibility to improve system efficiency and social equity through introducing non-rent seeking digital infrastructures and decentralized governance systems.
