Comparing and using prominent social accountability frameworks in medical education: moving from theory to implementation in Northern Ontario, Canada
Authors: Wood Brianne , Bohonis Hafsa , Ross Brian , Cameron Erin
Published: June 2022

Background: Social accountability in medical education is conceptualized as a responsibility to respond to the needs of local populations and demonstrate the impact of these activities. The objective of this study was to rigorously examine and compare social accountability theories, models, and frameworks to identify a theory-informed structure to understand and evaluate the impacts of medical education in Northern Ontario.
Methods: Using a narrative review methodology, prominent social accountability theories, models, and frameworks were identified. The research team extracted important constructs and relationships from the selected frameworks. The Theory Comparison and Selection Tool was used to compare the frameworks for fit and relevance.
Results: Eleven theories, models, and frameworks were identified for in-depth analysis and comparison. Two realist frameworks that considered community relationships in medical education and social accountability in health services received the highest scores. Frameworks focused on learning health systems, evaluating institutional social accountability, and implementing evidence-based practices also scored highly.
Conclusion: We used a systematic theory selection process to describe and compare social accountability constructs and frameworks to inform the development of a social accountability impact framework for the Northern Ontario School of Medicine. The research team examined important constructs, relationships, and outcomes, to select a framework that fits the aims of a specific project. Additional engagement will help determine how to combine, adapt and implement framework components to use in a Northern Ontario framework.
A virtual rural medicine self learning module for preclerkship students
Authors: DeBiasio Celina , Su Charles , Campbell Craig , Wood Timothy J
Published: June 2022

Implication Statement
All Ontario medical schools have a mandatory preclerkship rural placement. Despite these mandatory placements, there is a lack of Canadian rural medicine pre-departure training for students.  We describe a virtual self-learning module (SLM) aimed to enhance medical students’ abilities to provide compassionate care during their rural medicine placements. This SLM improves students’ knowledge about rural health issues while also encouraging exploration of rural career options. Better preparation for a rural medicine placement may lead to an improved experience and eventually an increase in the number of students pursuing rural medicine careers.
Cancel culture: exploring the unintended consequences of cancelling the Canadian national licensing clinical examination
Authors: Touchie Claire , Pugh Debra
Published: June 2022

Assessment drives learning. However, when it comes to high-stakes examinations (e.g., for licensure or certification), these assessments of learning may be seen as unnecessary hurdles by some. Licensing clinical skills assessment in particular have come under fire over the years. Recently, assessments such as the Medical Council of Canada Qualifying Examination Part II, a clinical skills objective structured clinical examination, have been permanently cancelled. The authors explore potential consequences of this cancellation including those that are inadvertent and undesirable. Future next steps for clinical skills assessment are explored.
Licensing exams in Canada: a closer look at the validity of the MCCQE Part II
Authors: Smirnova Alina
Published: June 2022

The Medical Council of Canada Qualifying Exam (MCCQE) Part II aims to protect societal interests through examining recently graduated physicians using clinical scenarios with standardized patients. This position paper debates the role of the MCCQE Part II in the national licensing of physicians in Canada by focusing on the consequential validity evidence of this exam and considering future directions through discussing contemporary developments in high stakes examinations. Specifically, this paper compares both MCCQE Part I and Part II in their ability to predict future practice patterns of physicians and generalizability across specialties. In weighing up the evidence this paper considers commonly used counterarguments as well as the financial implications of this exam for both the candidates and the MCC. Finally, it concludes by providing recommendations for future licensing of physicians in Canada. The available consequential validity evidence for MCCQE Part II is limited. Though still limited, MCCQE Part I has more robust evidence that it is a better predictor of future practice patterns compared to with Part II. Combined with a lack of evidence that national licensing examinations lead to graduation of substandard doctors or an improvement of care, and the shift away from assessment of learning towards assessment for learning, the maximum impact of the MCC on safeguarding public’s interests will lie in working closely with residency programs and specialty colleges to facilitate a robust assessment program of essential competencies and clinical skills during residency training and specialty certification.
THE GLOBAL IMPACT OF RUSSIAN AEROSPACE CLOSURE
Authors: Sopamena Chairussani Abbas
Published: June 2022

The war between Russia and Ukraine has a long tail and has spawned sanctions between countries. Aggressive Russia has taken the decision to close their airspace for many countries which became a policy that brought the world back to the similar conditions that happen in the cold war era. This article is written to answer the question, what is the impact of the closure of Russian airspace on the airline industry and the world economy? With using realism and structural functionalist approach this research shows that Russia's actions are taken to as a way deter other countries which support Ukraine. Thus, it is a clear indication that the existing international institutions along with their international law are indeed failed in dealing with the tendency of states (Russia) to act aggressively and halt their misconduct on their international interactions.

In the present work, we were interested in the study of the oscillatory phenomenon of ammonia-water two-phase flow inside the bubble pump of absorption-diffusion refrigerators. In fact, flow instability can reduce the efficiency of the bubble pump. The simulation of two-phase flow in the bubble pump is conducted by using the drift flow model. Balance equations of the drift flow model and their closure relationships, as well as the numerical method, were developed. The numerical resolution allowed defining the void fraction, the liquid and vapor velocities, the pressure, and the mixing enthalpy against time. The effect of heat flux received by the bubble pump is simulated in the transitional regime. Simulated results of the vapor, liquid, and mass velocities show a flow fluctuation at the beginning of the operation. The duration of the fluctuation increase from 6 s to 12 s by reducing the heat flux from 5 to 2 kW/m².The void fraction profile makes it possible to distinguish that the slug and churn regimes are those which dominate the pump’s operating regime for a heat flux of 2 and 3 kW/m². The pumping action is influenced by the heat flux. A maximum of 10 kW/m² value of heat flux is defined for an obtained minimum of the pumping action.

Modern nuclear medicine is a rapidly developing field that includes various non-invasive molecular imaging techniques with the ability to examine the whole body.

Inflammation is a frequent complication in surgical and traumatological practices, which is a complex, local and general pathological process that occurs in the body in response to injury. Having arisen under the influence of a damaging factor, inflammation is characterized by the development of a dynamic complex of changes. However, the search for inflammation foci of inflammation by traditional diagnostic methods in some cases is difficult even with a detailed clinical picture. In this case, nuclear medicine, which is able to visualize pathological processes, including those with a pathological increase in metabolism, may be the best option for finding the affected area.

A wide variety of radiopharmaceutical drugs makes it possible to determine the localization of the inflammatory focus in a short time and with high accuracy and makes nuclear imaging methods a priority for the early diagnosis of pathophysiological reactions.

This paper presents a review of domestic and foreign literature on the use of specific and nonspecific radiopharmaceuticals in the diagnosis of inflammation. Own cases is also presented.

Synovial sarcoma (SS) is a rare malignant soft tissue tumor that is associated with a high risk of distant metastasis, which significantly reduces patients` life expectancy. The analysis of volume indicators of PET/ CT)with 18F-fluorodeoxyglucose (FDG) was performed in two patients with the same grade of SS malignancy. The presented clinical cases demonstrate that in different patients with similar values 18F- FDG of the standardized uptake value (SUVmax) PET/CT volume indicators such as Metabolic Tumor Volume (MTV) and Total Lesion Glycolysis (TLG) can vary significantly, and therefore they can be additional prognostic factors for overall survival.

В статье предлагается метод определения массы корпуса наливных судов ледового плавания для начальных стадий проектирования. В основе предлагаемого метода лежит использование зависимостей, полученных путем регрессионного анализа результатов прямого расчета массы корпусных конструкций наливного судна и использование данных судна-прототипа. Прямым расчетом определялись массы наружной и внутренней обшивки, поперечного и продольного набора, верхней палубы и главных продольных и поперечных переборок, как наиболее влияющие на массу корпуса и зависимые от ледового класса элементы нагрузки. Прямой расчет массы корпусных конструкций проводился для каждого ледового класса по классификации РМРС в диапазоне проектных скоростей , уз, с учетом конструктивных особенностей, характеризующих принадлежность судна к определенному ледовому классу. Полученные зависимости для расчета массы корпуса в первом приближении, могут быть использованы в математической модели проектирования наливного судна ледового плавания при определении водоизмещения порожнем и последующей оценке стоимости постройки судна.

The article proposes a method for determining the weight of the hull of ice-going tankers for the initial stages of design. The proposed method is based on the use of dependencies obtained by regression analysis of the results of direct calculation of the weight of hull structures of a tanker and the use of data from a prototype vessel. The weights of the outer and inner shell, the transverse and longitudinal framework, the upper deck and the main longitudinal and transverse bulkheads were determined by direct calculation as the load components that most affect the weight of the hull and depend on the ice class. The direct calculation of the weight of hull structures was carried out for each ice class according to the RMRS classification in the range of design speeds , kn, taking into account the design features characterizing the ship's belonging to a certain ice class. The obtained dependences for calculating the weight of the hull in the first approximation can be used in the mathematical model of designing ice-going tanker when determining the lightweight and subsequent assessment of the cost of building the vessel.
The safety of a ship swaying under the influence of irregular winds and waves

При динамическом воздействии ветровой нагрузки обычно рассматривается отношение предельного выдерживаемого судном кренящего момента, называемого иногда минимальным опрокидывающим моментом, к расчетному кренящему моменту от давления ветра. Это отношение называется коэффициентом запаса остойчивости или критерием погоды, а также основным критерием. Оценка динамической остойчивости судна существенно осложняется, если в критерии погоды учитыва­ется кренящее действие не только ветровой нагрузки, но и набегающих волн. Суммарный эффект воздейст­вия кренящих моментов на судно зависит от целого ряда факторов: от характера набегающих волн, положе­ния судна по отношению к волнению, степени динамичности ветровой нагрузки, сдвига по фазе между креня­щим моментом от давления ветра и возмущающим моментом волнения. При построении критерия погоды отмеченные факторы могут быть учтены различным образом, в разной степени и в разных комбинациях, однако всегда стараются удовлетворить очевидным условиям: выбранная ком­бинация воздействия ветра и волн должна быть, с одной стороны, достаточно тяжелой в отношении остойчи­вости, а с другой, — вполне вероятной в смысле возможности ее возникновения в процессе эксплуатации.

During the dynamic impact of the wind load the ratio of extremely withstand heeling moment of the ship, sometimes referred to as the minimum overturning moment, to the calculated heeling moment from wind pressure is usually considered. This ratio is called the safety factor or the stability criterion of the weather, as well as the basic criterion. The Assessment of dynamic stability of the ship is significantly complicated if the criterion of the weather takes into account not only the heeling from wind load, but from the incoming waves also. The total effect of the heeling moments on the ship depends on several factors: the nature of incoming waves, location of the ship relative to the excitement, the degree of dynamic wind load, the phase shift between heeling moment from wind pressure and excited moment of the waves. When building a criterion of weather the above-mentioned factors can be taken into account in different ways, in different degrees and in different combinations, but always trying to satisfy the obvious conditions: the selected combination of impact of wind and waves should be, on the one hand sufficiently hard for stability and on the other, — it is probable in the sense that it occurs during operation.
Variations in physical and mechanical properties of model fine-grained ice during experiment

Определение физико-механических свойств моделированного льда является одним из важнейших этапов экспериментальных исследований в ледовом бассейне, предназначенном для изучения ходкости и управляемости судов во льдах, а также ледовых нагрузок на морские инженерные и гидротехнические сооружения. Подходы к выполнению таких измерений в ледовых бассейнах всего мира стандартизированы и соответствуют рекомендациям Международного Комитета Опытовых Бассейнов. Определённой особенностью экспериментальных исследований данного типа является то, что достаточно сложно с высокой точностью добиться требуемых значений толщины или прочности моделированного льда. В связи с этим разработаны и применяются методики корректировки результатов модельных испытаний. Но при этом остается открытым вопрос выбора времени для измерений свойств льда и частоты их выполнения, т.к. влияние длительности эксперимента на изменчивость физико-механических свойств льда изучено слабо. Данная проблема обусловлена еще и тем, что продолжительность модельных испытаний в современных ледовых бассейнах, отличающихся увеличенными размерами ледового поля, варьируется в зависимости от количества пробегов и уровня сложности исследований. В ледовом бассейне Крыловского Центра выполнены необходимые для изучения данного вопроса измерения в ровном льду, смоделированном по технологии FG, и сделаны выводы о влиянии температуры воздуха на основные характеристики ледяного покрова гранулированного типа. Полученные результаты направлены на снижение неопределённости результатов модельных испытаний в ледовом бассейне.

Evaluation of physical & mechanical properties of model ice is one of the most important aspects of experimental studies in ice basins designed to investigate ship propulsion and maneuverability in ice-covered waters as well as ice loads on engineering and hydraulic structures. These measurements in ice basins follow standard procedures across the world and comply with recommendations of the ITTC Committee. A certain specific feature of these types of experimental studies is that it is quite difficult to achieve the target thickness or strength values of model ice with a high accuracy. In this connection methods for correction of model test data have been developed and implemented. However, the time and frequency of measuring the ice properties remain an open question because the influence of experiment duration on variable physical & mechanical properties has been studied poorly. This problem is also caused by the fact that the test duration in modern ice basins capable of generating larger ice sheets varies depending on the number of test runs and particulars of studies. For investigation of this issue the Ice Basin of Krylov State Research Centre has conducted measurements in level ice modeled using FG ice technology and some conclusions have been drawn regarding the impact of air temperature on the main characteristics of FG ice type. The obtained results are aimed at reducing the uncertainty of model test results gathered in the ice basin.

Работа посвящена возможности использования пароводяного струйного аппарата (ПВСА) в качестве движителя на скоростных судах.Для достижения поставленной цели целесообразно использовать ПВСА, предназначенный для обеспечения циркуляции теплоносителя в первом контуре. Особенностью такого ПВСА является сверхкритическое течение среды в диффузоре.Рассмотрены варианты получения водяного пара путем сжигания водорода или водородосодержащего топлива в кислороде или воздухе. В качестве водородосодержащего топлива целесообразно использовать метан или аммиак. В камеру сгорания необходимо подавать воду для того, чтобы увеличить массовую долю водяного пара в парогазовой смеси.Установлено, что сверхкритическое течение среды в диффузоре рассматриваемого ПВСА позволяет использовать его в качестве движителя. Необходимо только так выбрать параметры ПВСА, чтобы скачка конденсации в диффузоре не было.

The work is devoted to the possibility of using a steam-water jet apparatus (PVSA) as a propulsion device on high-speed ships.To achieve this goal, it is advisable to use PVSA, designed to ensure the circulation of the coolant in the primary circuit. A feature of such a PVA is the supercritical flow of the medium in the diffuser.Options for obtaining water vapor by burning hydrogen or hydrogen-containing fuel in oxygen or air are considered. It is advisable to use methane or ammonia as a hydrogen-containing fuel. It is necessary to supply water to the combustion chamber in order to increase the mass fraction of water vapor in the gas-vapor mixture.It has been established that the supercritical flow of the medium in the diffuser of the PVSA under consideration makes it possible to use it as a propeller. It is only necessary to choose the PVSA parameters in such a way that there is no condensation jump in the diffuser.

В статье рассматривается определение нелинейных сил второго порядка, обусловленных взаимодействием различных видов колебаний на основании применения трехмерной потенциальной теории. Для их определения необходимо вычисление потенциалов второго порядка малости. Представленное решение в отечественной практике является новым. Решение задачи осуществляется на основании методов малого параметра и интегральных уравнений с учетом нелинейного граничного условия на свободной поверхностью жидкости. В работе расчет интегралов по свободной поверхности проводится напрямую за счет их сходимости на бесконечном удалении от судна. Нелинейные силы и моменты определяются в работе с использованием различных функций Грина: для бесконечно-глубокой жидкости и жидкости ограниченной глубины, когда H→∞. Полученные результаты практически полностью согласуются между собой. Приводятся результаты расчетов нелинейных сил и моментов для разных судов. Расчеты представлены в сравнении с расчетами по двумерной теории, выполненными также для случая бесконечно глубокой жидкости и жидкости ограниченной глубины при больших значениях отношения глубины к осадке H/T. Показано хорошее согласование результатов между собой в большинстве случаев. Показана возможность расчета нелинейных сил, возникающих при взаимодействии отдельных видов качки на произвольных курсовых углах.

The article considers the definition of nonlinear second-order forces caused by the interaction of various types of motions based on the application of three-dimensional potential theory. To determine them, it is necessary to calculate the potentials of the second order of smallness. The presented solution is new in domestic practice. The problem is solved on the basis of small parameter methods and integral equations taking into account the nonlinear boundary condition on the free surface of the liquid. The paper shows the possibility of calculating the integrals over the free surface directly due to their convergence at an infinite distance from the ship. Nonlinear forces and moments are determined in the work using various Green's functions: for an infinitely deep fluid and a fluid of limited depth when H → ∞. The results obtained are in almost complete agreement with each other. The results of calculations of nonlinear forces and moments for different ships are presented. The calculations are presented in comparison with the calculations according to the two-dimensional theory, performed also for the case of an infinitely deep liquid and a liquid of limited depth at large values of ratio H / T. A good agreement of the results is shown among themselves in most cases. The possibility of calculating nonlinear forces arising from the interaction of certain types of motions at arbitrary course angles is shown
Cuisines of Diaspora: Expressions of Iranian Foodways & Culinary Traditions
Authors: Kamal Nazmi , Chung Marian
Published: June 2022

The project "Cuisines of Diaspora" was a community-based research inquiry that aimed to expose the status quo of Iranian culinary culture within the decades-strong Iranian diaspora in the North Shore area of Vancouver, BC, Canada. Using a qualitative and interpretive approach with a
case study methodology, the research employed multiple tools using semistructured interviews, market observations, photovoice samples, and city archives, as well as other interactions with community members and stakeholders. Nineteen interview responses were obtained alongside a magnitude
of data through secondary research findings. The findings suggest a lack of regional Iranian cuisine representation in the North Shore and a thirst for a more diverse offering that reflect the various Iranian provinces. Furthermore, the findings illustrate the growth in dining entertainment
options including artistic cultural representations through song, dance, and other art forms. Other findings suggest a strong sense of gastrodiplomacy by the Iranian community, which supports advocacy and promotion of Iranian cuisine. Finally, there is an appetite for more community events
that highlight Iranian culture and cuisine and a potential for preserving food culture through community partnerships and sustainable sourcing of food ingredients.
Effectiveness Diagnosis of Pulmonary Tuberculosis (TB) in Children Based on Clinical Symptoms
Authors: Tinartayu Seshy , Syarrah Tiara Harrini
Published: June 2022

Background: Diagnosis of pulmonary tuberculosis (TB) in children is still a challenge because the gold standard by examining sputum AFB is difficult. This study aimed to see the effectiveness of diagnosing TB in children based on clinical symptoms.

Methods: This study is a retrospective study with a case-control design, and consecutive sampling from the medical records of pediatric TB patients at Panembahan Senopati Hospital, Bantul for the period January 2014 - December 2016. The total population is 90, and the sample is 73. Children diagnosed with a score (score 6) are in the control group (n=30), while children with a diagnosis score of <6 were diagnosed with pulmonary TB based on clinical symptoms, we categorized them into the case group (n=43).

Results: There was no difference in gender, age, and group domicile. However, there was no significant difference in nutritional status (malnutrition), long cough, and chest X-ray. The difference between the two groups was found in symptoms of fever and enlarged lymph nodes. Also, it was found in TB contacts and the Mantoux test but this could be a recall bias because in the diagnosis group this is rarely done. The sequential scoring parameters from the most common were chest X-ray, malnutrition, cough, enlargement of lymph nodes, fever, contact TB, and the Mantoux test. Improvement of symptoms (cough, fever, lymph nodes, and chest X-ray) after 6 months of therapy occurred 100% in both groups.

Conclusion: The diagnosis of TB in children based on clinical symptoms can be used as an effective alternative.

Authors: Arzoo Ralhan  , Muskan Sodhi
Published: June 2022

Background: Spinal block provides excellent anesthesia for cesarean section, but it is frequently accompanied byhypotension, which if untreated can pose serious risks to mother and baby. Over the years, many interventions have beentried to prevent hypotension, but no single technique has proven to be effective and reliable. This study was carried outwith the aim to find if wrapping the legs with elastic crepe bandage in addition to traditional methods was effective inpreventing post spinal hypotension.Materials and Methods: A total of 60 full-term parturients with an uncomplicated pregnancy belonging to AmericanSociety of Anesthesiologists I or II were allocated randomly (30 in each group) to have their legs wrapped with elasticcrepe bandage or no wrapping was done. All patients received intravenous (IV) crystalloid (20 ml/kg) 15 min priorto spinal injection and were placed in left lateral position. Electrocardiography and oxygen saturation was monitoredcontinuously and heart rate, blood pressure was measured every 2 min until delivery of baby and every 5 min thereafteruntil end of cesarean section. Significant hypotension was treated with IV phenylephrine 50 μg bolus doses.Results: The frequency of hypotension was significantly less (P = 0.009) in Group B (legs wrapped group) 3 (10%) patientswhen compared with Group A (nonleg wrapped) 13 (43.33%). In Group A 10 (33.33%) patients and in Group B 3 (10%)patients required rescue dose with phenylephrine which was statistically significant (P = 0.0003). Difference in the “meanchange of arterial pressure” between Group A and B was highly significant (P < 0.001) recorded at 4, 6, and 8 min.Conclusion: Incidence of hypotension can be reduced by wrapping the legs with elastic crepe bandage with a subsequentreduction in the use of potent vasopressor. Since leg wrapping with crepe bandage is cheap, easy, readily available,noninvasive, and nonpharmacological method, it can be recommended for preventing post spinal hypotension in adeveloping country like ours.

Type 2 diabetes mellitus and hypertension overlap in the population. In many subjects, development of diabetes mellitusis characterized by a relatively rapid increase in plasma glucose values. Whether a similar phenomenon occurs duringthe development of hypertension is not known. We analyzed the pattern of blood pressure (BP) changes during thedevelopment of hypertension in patients with or without diabetes mellitus using data from the MCDS and in the FOSduring a 7-year follow-up. Diabetes mellitus at baseline was a significant predictor of incident hypertension (in FOS,odds ratio, 3.14; 95% confidence interval, 2.17–4.54) independently of sex, age, body mass index, and familial diabetesmellitus. Conversely, hypertension at baseline was an independent predictor of incident diabetes mellitus. In comparisonwith the nonconverters group, hypertension and diabetes mellitus converters shared a metabolic syndrome phenotype(hyperinsulinemia, higher body mass index, waist girth, BP, heart rate and pulse pressure, and dyslipidemia). Overall,results were similar in the 2 ethnic groups. We conclude that (1) development of hypertension and diabetes mellitustrack each other over time, (2) transition from normotension to hypertension is characterized by a sharp increase in BPvalues, and (3) insulin resistance is one common feature of both prediabetes and prehypertension and an antecedent ofprogression to 2 respective disease states.

Background: In India, two most common substances for which people seek treatment are alcohol and opioids. Theconceptualization of personality in substance users shifted from the notion of an “addictive personality” to recognitionthat certain personality traits specifically impulsivity, sensation-seeking, novelty-seeking, low agreeableness andconscientiousness, high neuroticism are associated with substance use disorders and influence their development,maintenance and course.Methods: 70 people with alcohol related disorders and 70 patients with opioid related disorders diagnosed by DSM 5were interviewed with SADQ, LEEDS and NEO FFI3 to assess severity of substance related disorders and personality ofthose patients.Results: The study showed than neuroticism (32.25±4.22) was more in severe alcohol dependence patients and sowas extraversion (31.50±3.94). agreeableness (38.00±5.57) and conscientiousness (40.33±4.73) was more in the mildphysical dependency group. Openness to experience had similar ranges in all the 3 dependency groups. Neuroticism(38.25±3.55) was very high in high dependency OUD group and so was extraversion (34.92±3.65). Openness to experience,agreeableness and conscientiousness had neutral findings in all the three dependence category.Discussion: Previous studies showed agreeableness and conscientiousness were high in alcohol related disorders and inOpioid dependant patients neuroticism and extraversion were high. Our findings are also in the same way. Hence, therewas significant association between the personality profile factors and the type of substance dependence and severity.

Published: June 2022

Background: Previous studies propose that hypothyroidism might play a crucial role in the pathogenesis of non-alcoholicfatty liver disease (NAFLD), but findings from published studies on the relationship between hypothyroidism and NAFLDare still controversial. Our study aimed to make a comprehensive evaluation of the relationship between hypothyroidismand NAFLD through a meta-analysis.Methods: The pooled odds ratios (ORs) with 95% confidence intervals (95% CIs) were calculated to evaluate the strengthof the relationship between hypothyroidism and NAFLD through meta-analysis.Results: Thirteen articles were ultimately included in our meta-analysis. Meta-analysis of the 13 studies found a highcorrelation between hypothyroidism and NAFLD (OR = 1.52, 95% CI 1.24–1.87, P < 0.001). Meta-analysis of 9 studiesproviding adjusted ORs found that hypothyroidism was independently correlated with NAFLD (OR = 1.72, 95% CI1.32–2.23, P < 0.001). Subgroup analysis found that both overt hypothyroidism and subclinical hypothyroidism weresignificantly correlated with NAFLD, and the pooled ORs were 1.70 (95% CI 1.23–2.36, P = 0.002) and 1.40 (95% CI1.10–1.77, P = 0.006), respectively. Besides, meta-analysis of studies providing adjusted ORs also found that both overthypothyroidism and subclinical hypothyroidism were independently correlated with NAFLD, and the pooled ORs were1.81 (95% CI 1.30–2.52, P < 0.001) and 1.63 (95% CI 1.19–2.24, P = 0.002), respectively.Conclusion: The meta-analysis provides strong epidemiological evidence for the relationship between hypothyroidismand NAFLD. Both individuals with subclinical and overt hypothyroidism are at higher risk for NAFLD than euthyroidsubjects.

Published: June 2022

Abstract

Background/problem: Road traffic injuries are the leading cause of injury and death in the productive age group. Two-wheeler riders accounted for nearly half of fatal and nonfatal injuries. Head injury is the most common cause of death

among them, which can be reduced by the appropriate use of the helmet. Though there was a law about the compulsorywearing of a helmet in the state, it was never enforced in the district and helmet usage rate in a district before the campaignvaried from 1% to 5%.Methods: ‘Helmethon’, a unique multi-faceted Campaign in the district of India was carried out for a period of threemonths in the year 2015 to promote helmet for prevention of head injuries. The campaign targeted the general public witha special focus on youth and stakeholders, who are responsible for enforcement of helmet legislation.Results: Campaign was successful in sensitizing the community and drawing the stakeholder’s attention towards theimportance of preventing head injuries through enforcement of helmet law. The law was enforced in Tumkur district inless than a fortnight following the campaign and helmet usage rate among riders soon after enforcement had increasedto 80% from a mere 1%.Conclusion: A well planned and committed helmet campaign shall sensitize the community regarding helmet safety andencourages them to use it. It also influences stakeholders to enforce the helmet law with the least resistance.

Background: Blood is a specialised connective tissue that gives each individual their identity by determining theirblood group and type. In transfusion medicine, the blood group has clinical significance. Malnutrition is one of theworld’s significant health issues, with anaemia accounting for a significant proportion of the problem, particularly inunderdeveloped nations. Reduced haemoglobin levels have an unfavourable effect on the functioning of other humanbodily systems. The association between blood groups and disorders including stomach cancer and pernicious anaemiahas been established. Previously, several research examining the relationship between anaemia and different bloodtypes yielded mixed results. As a result, the current study was conducted in order to shed light on blood groups andhaemoglobin (Hb) levels.Objectives: To determine if there is a relationship between blood group distribution and the prevalence of anaemiaamong young medical students based on the variations of haemoglobin concentration of individuals.
Materials& Methods: First-year MBBS and BDS students enrolled to GMC Jammu in the academic year 2020-21 wereused as subjects, and blood grouping was performed using the conventional antisera slide agglutination method. Withthe use of Sahli’s hemoglobinometer, the participants’ haemoglobin content was calculated. Hb less than 13 g/dl for males and less than 12 g/dl for females was deemed anaemia.
