Authors: Vajravelu Ashok , Selvan K.S. Tamil , Jamil Muhammad Mahadi Bin Abdul , Jude Anitha , Diez Isabel de la Torre
Published: September 2022

Wireless Capsule Endoscopy (WCE) allows direct visual inspecting of the full digestive system of the patient without invasion and pain, at the price of a long examination by physicians of a large number of photographs. This research presents a new approach to color extraction to differentiate bleeding frames from normal ones and locate more bleeding areas. We have a dual-system suggestion. We use entire color information on the WCE pictures and the pixel-represented clustering approach to get the clustered centers that characterize WCE pictures as words. Then we evaluate the status of a WCE framework using the nearby SVM and K methods (KNN). The classification performance is 95.75% accurate for the AUC 0.9771% and validates the exciting performance for bleeding classification provided by the suggested approach. Second, we present a two-step approach for extracting saliency maps to emphasize bleeding locations with a distinct color channel mixer to build a first-stage salience map. The second stage salience map was taken with optical contrast.We locate bleeding spots following a suitable fusion approach and threshold. Quantitative and qualitative studies demonstrate that our approaches can correctly distinguish bleeding sites from neighborhoods.
Fault tolerant data offloading in opportunistic fog enhanced IoT architecture
Authors: Kaur Parmeet
Published: September 2022

Internet of Things (IoT) is characterized by the large volumes of data collection. Since IoT devices are themselves resource-constrained, this data is transferred to cloud-based systems for further processing. This data collected over a period of time possesses high utility as it is useful for multiple analytical, predictive and prescriptive tasks. Therefore, it is crucial that IoT devices transfer the collected data to network gateways before exhausting their storage to prevent loss of data; this issue is referred to as the “data offloading problem”. This paper proposes a technique for fault tolerant offloading of data by IoT devices such that the data collected by them is transferred to the cloud with a minimal loss. The proposed technique employs opportunistic contacts between IoT and mobile fog nodes to provide a fault tolerant enhancement to the IoT architecture. The effectiveness of the proposed method is verified through simulation experiments to assess the reduction in data loss by use of proposed data offloading scheme. It is demonstrated that the method outperforms a state-of-art method.
A survey on cloud computing scheduling algorithms
Authors: Malekimajd Marzieh , Safarpoor-Dehkordi Ali
Published: September 2022

Cloud computing has emerged as one of the hottest topics in technology and has quickly become a widely used information and communication technology model. Performance is a critical component in the cloud environment concerning constraints like economic, time, and hardware issues. Various characteristics and conditions for providing solutions and designing strategies must be dealt with in different situations to perform better. For example, task scheduling and resource allocation are significant challenges in cloud management. Adopting proper techniques in such conditions leads to performance improvement. This paper surveys existing scheduling algorithms concerning the macro design idea. We classify these algorithms into four main categories: deterministic algorithms, metaheuristic algorithms, learning algorithms, and algorithms based on game theory. Each category is discussed by citing appropriate studies, and the MapReduce review is addressed as an example.
The role of female volunteers in disaster response organisations: A qualitative research
Authors: Ekşi Ali , Utanır Altay Sinem , Gümüşsoy Süreyya
Published: September 2022

BACKGROUND: Despite a high demand for people to participate in disaster volunteering, the extent of contribution received from female volunteers in disaster response organisations constitutes an important debate. In the Elazığ earthquake on 24 January 2020, the role of female volunteers in rescuing a female victim from the wreckage once again demonstrated the importance of considering female volunteers when creating response capacities for disaster risks. OBJECTIVE: This qualitative study aims to evaluate the roles of female volunteers who play an active role in disaster response organisations in a society with gender equality issues. METHODS: This qualitative study included 15 National Medical Rescue Team (UMKE) female volunteers who took an active role in the Elazig earthquake and was performed between 15.07.2020 and 16.04.2021. Data were collected using an in-depth interview method. The data were analyzed using content analysis and the comments were given descriptively. RESULTS: Based on the qualitative analysis, the following concepts were explored among the participants: Volunteering, volunteering in disasters, the effects of volunteering on social life, being a woman in disasters, volunteering female in disasters, the ‘motherhood myth’, gender inequality. Women are key actors in tackling disaster damage and increasing available social resilience to disasters. In addition, women can use special attributes such as motherhood, which is socio-culturally defined and taught as an advantage, for the common good of society. Moreover, special elements, such as the image of the ‘superwoman’ in relation to the responsibilities imposed on women in disaster response organisations, which distort gender equality against women, appear as possible factors of harm for women. CONCLUSION: This study shows that female volunteers can play a life-saving role in chaotic situations such as disasters, contribute to the empowerment of women, increase sensitivity to gender and, in connection with this, the development of democracy in societies where gender inequality is high. On the other hand, special situations such as the image of ‘superwoman’, which aims for excellence in both private and public spheres in the responsibilities imposed on women, can destroy gender equality against women and increase women’s fragility.
The experience of meaningful rehabilitation as perceived by people with chronic pain: A phenomenological study
Authors: Liddiard Katrina J. , Raynor Annette J. , DeJong Helen , Brown Cary A.
Published: September 2022

BACKGROUND: People with chronic pain may seek rehabilitation to reduce pain and restore productivity and valued roles. Theoretically, a biopsychosocial approach makes rehabilitation more meaningful, however, the limited research on meaningful rehabilitation predominantly describes the perspective of therapists and researchers. The client’s perspective of meaningfulness in rehabilitation is lacking. OBJECTIVE: To investigate the experience of meaningfulness in rehabilitation from the perspective of people with chronic pain. METHODS: Qualitative, semi-structured interviews were conducted with Australian adults who had chronic pain and recent experience of occupational therapy or physiotherapy. Sampling continued until thematic saturation occurred. Transcripts were coded and analyzed using theory-driven and data-driven thematic analysis. RESULTS: Ten participants (four males; six females) were interviewed. Pain histories ranged from nine months to 20+ years, with conditions such as fibromyalgia or trauma. Three themes from a prior concept analysis were upheld, and a further three data-driven themes emerged. Results indicate that people with chronic pain seek a “genuine connection”; from a therapist who is “credible”; and can become a “guiding partner”, and they find rehabilitation meaningful when it holds “personal value”; is “self-defined”; and relevant to their sense of “self-identity”. CONCLUSIONS: The genuine connection and guiding partnership with a credible therapist, that is sought by people with chronic pain, may be at odds with aspects of contemporary rehabilitation. Client-defined meaningfulness is an important construct to engage clients in treatment and improve work and other occupational outcomes for people with chronic pain.
TUBERCULAR TESTICULAR ABSCESS: A CASE REPORT
Authors: Parse Rocci Jack , Agil Ahmad
Published: September 2022

Objective: This study aims to provide fellow physicians a better insight in diagnosing and managing similar cases. Case(s) Presentation: A 36 year old male presented to the emergency department with a chief complaint of red, painful, and progressively enlarging swelling of the left scrotal pouch since 1 week ago. The patient had a history of similar complaint and recurrent cloudy urine which were left untreated 1 year before. Based on physical examination and ultrasonography findings, the patient was diagnosed with left scrotal abscess and was treated by incisional drainage of abscess and necrotomy debridement under spinal anesthesia. Discussion: Tuberculosis infection of scrotal contents is rare and occurs in approximately 7% of the patients with tuberculosis, although tuberculosis itself is a global epidemic with more than 2 billion of the world population infected. In patients with genital tuberculosis, pulmonary and renal tuberculosis can be documented in 50% and 80-85% respectively. It is often secondary to the pre-existing tuberculosis of the urinary tract, which may be confirmed by the culture of early morning urine specimens. Conclusion: Treatment of testicular abscess is administration of appropriate antibiotics according to its causative organism accompanied by surgical drainage. Early diagnosis and prompt treatment of testicular abscess is necessary, since chronic and severe cases, as happened in this patient, usually resulted in nonviable testicular tissue and necessitate orchidectomy. This may be due to cumulative ischemia of the testicles from multiple mechanisms: inflammatory infiltration causing compression of the spermatic cord, thrombosis secondary to venous congestion and/or bacterial exotoxins.

Application of deep learning algorithms detecting fake and correct textual or verbal news
Authors: Dadvandipour Samad , Khaleel Yahya Layth
Published: September 2022

Abstract. The ongoing spread and expansion of information technology and social media sites have made it easier for people to access different types of news – political, economic, medical, social, etc. through these platforms. However, this rapid growth in news outlets and the demand for information has blurred the lines between real and fake news and led to the dissemination of fake news, which is a dangerous state of affairs. The outbreak of the coronavirus pandemic and awareness of the threats posed all across the globe. And a parallel rise in fake news and rumors, like unsubstantiated statements and deceptive ideas, were noticed. The main aim of this study is supposed to set out to overcome these kinds of problems in the future with the application of deep learning algorithms (LSTM, Bi-LSTM, BERT), using a large dataset (39279 rows) to identify fake and correct textual or verbal news. The results of the deep learning application using different algorithms show that the BERT model performed the best, achieving a text classification accuracy of 96.63 %.

Published: September 2022

The article examines the purpose, methods and tools of the monetary and credit policy of the National Bank of Ukraine. It is determined that the NBU is the main State-authorized institution in Ukraine, which is responsible for planning and implementing monetary and credit policy. Monetary and credit policy is a complex of measures in the field of money circulation and credit, which are intended to ensure the stability of the monetary unit of Ukraine due to the introduction of regulated by law funds and techniques. It is established that the financial sector is the key element of the national economy; its vital functions ensure the sustainable development of the economy, the creation and distribution of financial resources and services, the accumulation of investment capital, as well as the improvement of macroeconomic and monetary indicators. In today's harsh conditions such as: rising inflation, destruction of transport infrastructure, decline of business, reduction of sown areas, blockade of ports, devaluation of the UAH, growth of the budget deficit, issues of monetary regulation are becoming extremely important. The war projected on the country's economy, has become a difficult challenge for the National Bank in improving and adjusting the current monetary and credit policy, finding innovative mechanisms for its implementation. Carrying out an active foreign policy, attracting funds from the IMF, the World and European Banks, opening a special account to raise funds from individuals - these are some of the tools used by the NBU in wartime. On the other hand, the pressure on the world community is aimed at ending trade relations with the aggressor country, helping to minimize any attraction of funds into the Russian budget, thus depriving them of the opportunity to finance the war. Another important tool is the analysis of the world experience of countries in resolving the postwar crisis, and the adoption of their tools and mechanisms for economic recovery - all this is the purpose of this article.
The Russian-Ukrainian War Crisis as Part of the Profound Global Transformation Process: The Financial Mechanisms for Stabilization and Recovery
Authors:   Institute for Economics and Forecasting of NAS of Ukraine, Kornіvska Valerіia O.
Published: September 2022

The article is aimed at characterizing the modern crisis caused by the Russian-Ukrainian war as part of the profound world transformation process, and theoretical-methodological substantiating of the financial mechanisms for stabilization and recovery of the Ukrainian economy. As a result of the carried out study, it is shown that the current crisis in Ukraine is a component of the global transformational transition against the background of the formation of the information and digital economy. On the surface of economic phenomena, this transition is presented as: destabilization as result of the conflict adaptation of the networked person and the social simplification of the classical market entity; the clash of the fading liberal model of the world order and the beginnings of a new digital society; the crisis of globalization and localization. The stages of the unfolding crisis of globalization and localization are the following: the global financial and economic collapse of 2007-2009, the COVID-19 pandemic of 2020-2021, the stage of maximum entropy during the Russian military aggression against Ukraine in 2022. In the context of the crisis of globalization and localization, the role of the State-owned institutions is growing, which absorb global fluctuations and take maximum responsibility for themselves, creating risks for the formation of authoritarian societies. Simultaneously, with the crisis uncertainty growing, this is the most likely option to ensure relative stability and consistency. Financial mechanisms for stabilization and recovery of the Ukrainian economy should be implemented on the basis of the use of digital technologies to ensure supply and demand through the introduction of digital currency, the institution of unconditional income, the development of programs for automatic assistance to small and medium-sized enterprises in the context of crisis, the creation of financial development institutions in the format of a digital bank. Digital technologies will increase the risks of final leveling of market principles of economic activity and cause excessive overregulation, so further research in this direction will be focused on minimizing the risks of totalitarianization of the financial space in the digital economy.

El diagnóstico de glaucoma se realiza teniendo en cuenta múltiples factores: el historial médico, la valoración clínica del nervio óptico, el valor de la presión intraocular, la gonioscopía y estudios paraclínicos estructurales y funcionales, entre otros.6,14 De estos, la correcta valoración clínica del nervio óptico es parte fundamental y toma en cuenta, a su vez, aspectos como el tamaño de la papila, la rotación, la inserción, las fibras circundantes, la vasculatura y uno de los aspectos más importantes y usado como la referencia más frecuentemente usada: el valor de la relación copa/disco (RCD).
El objetivo de este estudio es conocer la variabilidad del cálculo de proporciones que hacen médicos evaluadores en entrenamiento y con especialidad en glaucoma, en figuras geométricas precisas como lo son los círculos concéntricos.
Este estudio, ejecutado con círculos concéntricos medidos objetivamente, nos muestra que la variabilidad atribuible al determinar proporciones no es significativa con respecto a la reportada en nervios ópticos en vivo; sin embargo, sí contribuye a sumarse a la variabilidad total, sobre todo en relaciones copa/disco pequeñas e intermedias.

Published: September 2022

The international literature on the examination of inductive reasoning is rather rich. Approaching it from the direction of soft skills can be considered still novel. The main objectives were to draw a picture of the development level of first-grade teacher students’ inductive thinking, to analyse the time used for the solution of tasks and task items and finally to explore the interconnection between solution time and the performance achieved in the inductive test. According to the results of 204 students attending teacher training at J. Selye University in Slovakia, the abstract and analogue reasoning of these students is of medium development level, while their diagrammatic thinking is weaker. There is a connection between the time used for the items and the test results, both the task types and the students can be classified according to time consumption. The 10% having reached the best results are women, have parents with a degree, live in cities and took their secondary school leaving exams at secondary grammar schools Hungary. Female and correspondence students spent more time on solving the tasks than male and full-time students.

Integrated Wastewater and Waste Heat Recovery System in Coal-Fired Power Plants Using Reverse Osmosis to Produce Clean Water and Increase Thermal Efficiency
Authors: Brilian Vincentius Adven , Aulia Sasa , Octaviani Farah , Khalfani Thariq Arian
Published: September 2022

Indonesian electricity supply is still dominated by coal-fired power plants (CPP) by more than 50%. Water consumption for CPP in Indonesia reaches 222 million kL/year. Meanwhile, 10% of Indonesia's population is predicted to experience a clean water crisis in 2045. Most of the water consumed by CPP will be disposed of as wastewater, such as cooling tower blowdown and boiler blowdown. Boiler blowdown temperature is still relatively high. Thus, it wastes a high-quality of energy. Therefore, these conditions open the opportunity for innovations in improving clean water supply and increasing CPP’s thermal efficiency. In this research, a novel system that integrates wastewater recovery and waste heat recovery in CPP using reverse osmosis is proposed to produce clean water while increasing the CPP’s thermal efficiency. In this system, the boiler blowdown is streamed to a heat exchanger as the feedwater preheater. Then, the boiler blowdown flows to a Pelton turbine to generate electricity. The boiler blowdown will then be mixed with the cooling tower blowdown and streamed to a reverse osmosis system to produce clean water. The brine is converted by an electrolyzer into NaClO and H2. Thermodynamic and economic analyses are performed to assess the proposed system’s technical and economic feasibility. Based on the thermodynamic analysis calculation using the Engineering Equation Solver, the system is able to produce 162 kL/hr of clean water and the thermal efficiency of the coal-fired power plant increases by 0.4%. The economic analysis showed that the additional system is feasible with a payback period of 4.9 years.
A Critical Analysis of China’s Role in Global Energy Governance as a Strategy for Energy Security and Seeking Hegemony
Authors: Hawkins Diemas Sukma , Sari Nirmala , Chaerunnisa Indah , Kuraini Farahdiba
Published: September 2022

In the turn of the twenty-first, China has grown to become the largest energy consumer in the world, the largest energy producer globally and has risen to prominence as one of the leaders in the development of alternative and renewable energy sources. This has granted China the status as a leader in global energy governance. But while China has actively participated in international energy markets as a massive competition, this has also been juxtaposed with an odd reluctance to ambitiously participate in global energy regimes. However, under President Xi Jinping this has changed, and China has become more and more dominant in the global energy sector; not just in the market but now in its governance. From its inclusion in international energy institutions to its role in energy development in the Belt and Road Initiative, BRICS and New Development Bank; we can now see how China has expanded its dominance in the energy sector. By using qualitative methods, this paper critically analyses China’s strive to become a global hegemony via dominance in the energy development sector, both as a tool for its energy security as well as to hold geopolitical control over developing nations that rely on China for their energy needs.

Published: September 2022

Este artículo describe una propuesta metodológica para generar una recuperación de los recursos que invierten las empresas en equipos (planta y equipo médicos) para mejorar su productividad. Con el tiempo, estos activos fijos se deprecian y dejan de utilizarse, quedando categorizados como improductivos. Por tal razón, se propone una estrategia de salida de estos activos fijos improductivos que involucre a los colaboradores de la empresa en la adquisición de estos. Además, se presenta una validación de este propuesto mediante un instrumento de tipo encuesta aplicado al personal de una empresa del sector asistencial en Colombia. El análisis muestra que con el modelo de gestión de activos fijos propuesto se recuperaría una fracción de la inversión económica que la empresa ha realizado en la compra de estos equipos, pero se incrementaría el sentido de pertenencia de los colaboradores de la organización.

Authors: Islam Ashraful , Alim Md Abdul , Islam Md Shafiqul , Deb Subrata , Mahmud Md Shaleh
Published: September 2022

Purpose: Urinary stone disease is a systemic metabolic and recurrent disease. It is the third most common disease of the urinary tract. Urolithiasis affects 4%-15% of the world population and this is increasing. Treatment of urinary stone disease moved dramatically from open operative procedures to endoscopic, minimally invasive, and noninvasive methods. The introduction of shock wave lithotripsy (SWL) has revolutionized the treatment of urinary stones with the concept of disintegration of stones. The present study aims to evaluate the outcome of SWL in the treatment of urinary stone disease.
Methods and Materials: This retrospective observational study was conducted in the department of urology, SOMCH from June 2019- to March 2021. Renal stone <2.0 cm & upper Ureteric stone <1.5 cm were included and radiolucent stones, patients having ureteral obstruction with grossly impaired renal function, UTI, uncontrolled bleeding disorder, pregnancy & BMI >30kg/m2 were excluded. A total of 115 patients was enrolled. SWL with Siemens Lithoskope (3rd generation) lithotripter was used with a standard number of shock waves 2500-3500 per session & an energy setting of 3.0-3.5 KV. NSAID was given in suppository form and intravenous pethidine just before starting shock for analgesia and all were under antibiotic prophylaxis. Patients were discharged the day after the SWL procedure with the advice of follow-up every 2 weeks for 3 months. All patients were followed up with history, urine R/M/E & C/S to detect UTI, plain X-ray KUB region to see stone clearance or any other complications.
Results: Total 179 sessions of SWL procedure done for 115 patients (1.55/ patient) with the urinary stone of both gender between 19 to 70 years. Of them, 82(71.3%) were male and 33(28.7%) female and 94(81.5%) were in the 20-60 years age group. Renal stones 78(67.9%), upper ureteric stones 37(32.1%), and 70(60.8%) were on the left side. Preprocedure stenting was done in 35(30.4%) patients due to obstruction & residual stones. 70(60.9%) have achieved stone clearance after the first session of SWL. After a maximum of 3 sessions of SWL and 3 months follow up found that 99(86%) patients were stone-free. Only 16(14%) found treatment failure and needed auxiliary procedures like URS, RIRS, etc because of hard stone, steinstrasse, and patients’ non-compliance due to pain & fearlessness. 13(11.3%) patients complain of moderate pain after SWL and needed a maximum of 2 days of hospitalization with an injectable pain killer. UTI was found in 9(7.8%) patients, of the 7(6.1%) were pre-stenting. Gross hematuria was found in 2(1.7%) patients due to HDN & UTI.
Conclusion: As the stone clearance rate is high with fewer complications however multiple sessions are required, SWL, a noninvasive procedure, is a good option for the treatment of urinary stone disease.

Introduction: This study is an effort to develop an alternative to available graft sources for complex and long-segment strictures. For this to assess the outcome of harvesting a full-thickness abdominal skin graft for urethral reconstruction we conducted this study.
Material and Method: The study was prospective type of observational study. Data were collected between June 2019 and November 2021 from patients underwent urethroplasty using full thickness skin grafts harvested from abdominal skin.
Result: Total 16 patients followed up. Mean stricture length was 8 + 3.38 cm (range 5-12 cm). The aetiology [Figure 2] of urethral stricture included urethritis (6 patients), urethral trauma (7 patients), failed hypospadias repair (2 patient) and unknow (1 patient). The mean prepared graft length was 8.68 + 4.58 cm (range 7–14 cm), the mean operation time was 86.45 + 30.28 minutes (range 55 –130 minutes). Median follow-up was 24 months. 2 patients developed febrile urinary tract infections requiring oral antibiotics. 1 patient with history of urethritis developed recurrent stricture. So overall success rate is 93.75% with p value of < 0.001; that is statistically significant.
Conclusion: Selective use of abdominal skin grafts may be well suited for patients with long-segment urethral strictures in one or two stages when other graft sources are not available or feasible.

Cystic Renal Cell Carcinoma – Sometimes A Diagnostic Dilemma: A Case Report on Rare Multilocular Cystic Renal Cell Carcinoma
Authors: Shaikh Azfar Uddin
Published: September 2022

Cystic renal tumors often create diagnostic dilemma. It might be a cancer in a complex cyst, cystic degeneration of a renal cell carcinoma, Papillary cystic renal cell carcinoma or multilocular cystic renal cell carcinoma (MCRCC). MCRCC is a rare cystic tumor of the kidney. It is recognized as a separate subtype of renal cell carcinoma in WHO classification of adult renal tumors in 2004 with excellent prognosis. A 47 years old male presented with an incidentally detected large right renal cystic lesion in the upper and hilar region. After discussion with the patient about the possibilities, right radical nephrectomy was performed. Histopathology was done by one of the renowned Pathologists of the country and was reported as a rare variety Multilocular Cystic Renal Cell Carcinoma. It is very important to differentiate this type of cystic renal cell carcinoma from cystic degeneration of conventional RCC.

Published: September 2022

Bladder urothelial carcinoma (UC) it is the fifth most prevalent carcinoma in humans, nevertheless in children and young adults it’s very rare. It usually occurs in older adults. We present a 4-year-old boy with a painful microscopic hematuria. Ultrasound revealed a irregular lobulated mass lesion in right supero-lateral wall of urinary bladder and a thick bond extending towards left lateral wall which was confirmed by computed tomography (CT). The first biopsy was compatible with urothelial papilloma. Transurethral resection of the bladder tumor (TURBT) was performed and histopathology showed urothelial neoplasm of low malignant potential (PULMP).

Breaking the Pilot Healthcare Barrier

Published: September 2022

INTRODUCTION: It has been proposed that pilots face a perceived barrier to seeking medical care due to what a change in health status might mean to their status as a pilot. While this is often common knowledge to pilots and some physicians, this phenomenon has limited research
or characterization in the medical literature. In this commentary, we propose a definition for the barrier pilots face in seeking healthcare in hopes of focusing future research efforts.Hoffman W, Bjerke E, Tvaryanas A. Breaking the pilot healthcare barrier. Aerosp Med Hum Perform.

Hereditary Angioedema Management: From Dealing to Leading
Authors: Porębski Grzegorz , Cancian Mauro , Aygören-Pürsün Emel , Caballero Teresa
Published: September 2022

A two-part digital symposium series entitled ‘Hereditary Angioedema (HAE) Management: From Dealing to Leading,’ took place during the European Academy of Allergy and Clinical Immunology (EAACI) Hybrid Congress, held in Prague, Czechia, in July 2022. The first symposium, ‘The Journey Towards Disease Control in HAE’, held on 1st July 2022, was chaired by Markus Magerl, Department of Dermatology and Allergy, Charite Universitätsmedizin, Berlin, Germany. Speakers Grzegorz Porębski, Department of Clinical and Environmental Allergology, Jagiellonian University Medical College, Kraków, Poland, and Mauro Cancian, Department of Systems Medicine, University of Padova, Italy, discussed how the advent of new disease-specific HAE treatments have contributed to the evolution of the HAE management guidelines, and the resulting impact on the lives of patients with HAE. The latest international management guidelines from the World Allergy Organization (WAO)/EAACI newly define the goals of treatment in HAE as achieving total control of the disease and normalising patients’ lives, stressing that this can currently only be achieved by long-term prophylactic (LTP) treatment. The second symposium, ‘Making the Goals of HAE Management Achievable with Subcutaneous C1-Inhibitor’, held on 2­nd July 2022, was chaired by Pavlína Králíčková, Department of Clinical Immunology and Allergology, University Hospital Hradec Králové, Czechia, who also provided a brief overview of the development of the subcutaneous formulation of C1-inhibitor for LTP. Emel Aygören-Pürsün, Angioedema Clinic and Center for Hereditary Angioedema, University Hospital Frankfurt, Goethe University, Germany, and Teresa Caballero, Allergy Department, Hospital Universitario La Paz, Madrid, Spain, then used case studies to highlight the necessity of assessing and monitoring a patient’s disease activity, the associated quality of life, and disease control to allow for possible adaptations to the treatment plan. Both speakers also highlighted how the use of subcutaneous C1-inhibitor for LTP can contribute towards the achievement of the goals of HAE treatment, namely achieving total disease control and normalising patients’ lives.
‘Why does Africa matter and what should be our aim?’ British Foreign Policy, the Commonwealth, and the 1965 East and Central African Heads of Missions Meeting
Authors: Cullen Poppy
Published: September 2022

This article explores British decolonisation through the lens of the first meeting of Britain’s Heads of Missions (Ambassadors and High Commissioners) in East and Central Africa in May 1965. The meeting gives a unique insight into the thoughts and ambitions of a select group of senior diplomats as they offered their ideas of what policy should be and assessed Britain’s historical and contemporary relationship with Africa. Mid-1965 was a moment when multiple, if limited, options were available as the British government sought to reconfigure relationships and preserve influence in former colonies. The meeting is significant in a number of ways. Firstly, the meeting was an expression of power relations between different government departments in Whitehall, with the Commonwealth Relations Office valuing Africa more than the powerful Foreign Office; secondly, it reinforced the diplomats’ sense of their position as supposed ‘experts’ on Africa, more advanced and rational than the Africans with whom they worked; thirdly, it revealed official beliefs that Britain was the more powerful partner in relationships with Africa, able to exert influence though ongoing bilateral relationships and the Commonwealth.
