The Concept of Economic Operator and the Setting of Limitations to Awarding by Lots in Public Procurement in the Light of the Portuguese Public Contracts Code
Authors: Cunha Rodrigues Nuno
Published: December 2021

According to the EU 2014 directives, the contracting authority should divide into lots – or to justify not doing so. Furthermore, it may decide (i) to limit the number of lots to which each economic operator may submit tenders; (ii) to limit the maximum number of lots to be awarded per economic operator, or (iii) to aggregate all or part of the lots. In view of the limitation on the number of lots for which tenders may be submitted or the maximum number of lots to be awarded per competitor – either limitation to be determined in advance at the contracting authority’s discretion – the article addresses the question of whether albeit legally distinct competitors that maintain an economic unit or interdependent links may submit bids for different lots or groups of lots in the same procedure.

Malnutrition and the Risk of Catastrophic Health Expenditure in Nigeria
Authors: Sato Ryoko
Published: December 2021

BACKGROUND: Malnutrition among children not only affects their health consequences but also does it burden their households’ finance especially in developing countries. This study evaluates the household risk of catastrophic health expenditure (CHE) due to malnutrition treatments among malnourished children in Nigeria, according to zones and wealth quintiles. We simulate the CHE risk among households with malnourished children who seek treatment. 

METHODS: The CHE risk due to malnutrition among treated was computed based on 1) the out-of-pocket (OOP) expenditure and indirect costs associated with malnutrition treatment, and 2) household consumption expenditures. I derived the CHE risk associated with malnutrition across zones and wealth quintiles in Nigeria, using secondary data sources for healthcare utilization, OOP expenditures, and consumption expenditures.

RESULTS: There was a large variation of CHE risk according to zones and wealth quintiles. Among the poorest households, those in northeast and northwest would have the highest risk of CHE, up to 59 and 47%, while those in southwest would have the lowest risk of 14%. For all zones, as the wealth increases, the CHE risk would decrease. There would be zero or very little CHE risk among the richest households in any zones.

INTERPRETATION: Nutrition interventions will help malnourished children improve their health status. However, we should also be wary about the financial consequences of the treatment that households should bear.

The lure of administrative narrowness: blame and time in COVID-19 crisis management

As public institutions seek to come to grips with the crisis of COVID-19, they risk getting trapped in a unilateral here-and-now crisis management style that overlooks other long-term societal issues. We raise the question how and why this is the case. What makes here-and-now crisis management so ‘attractive’ from a political-administrative perspective? Through which strategies is this style being promoted? Guided by the literature on blame management, we empirically analyze the Dutch COVID-19 crisis communication. We specifically zoom into a pivotal yet underexposed facet: the role of time. Three time-related blame management strategies are empirically explored and interpreted: 1) playing with the time horizon; 2) organizing self-reinforcing institutional rhythms of monitoring and decision-making; 3) selectively naming uncertainties and risks. All three subtly add to a short time horizon in managing the COVID-19 crisis, revealing how interwoven time and blame are in public decision-making.
Investeren in de toekomst na COVID-19: speelt de crisis een rol in partijpositionering?

Investing in the future after COVID-19: does the crisis play a role in party-positioning?

Do the budgetary consequences of an acute crisis make us less willing to tackle long-term challenges? This paper asks whether the recent COVID-19 crisis has affected the willingness of parties to commit to so-called ‘policy investments’. These are policies where short-term costs are accepted in anticipation of higher benefits in the longer run. Theoretically, there is no unambiguous prediction as to whether the recent crisis plays a role in repositioning party preferences regarding policy investments. In light of this theoretical ambiguity, this article aims to provide an empirical answer by measuring and comparing party positioning regarding policy investments of Dutch parties during the two general elections for the House of Representatives (Tweede Kamerverkiezingen) of 2017 and 2021 respectively. To identify which proposals qualify as policy investments, and measure the corresponding willingness to engage in them, the article builds on calculations of the budgetary impact of party manifestos provided by the Netherlands Bureau for Economic Policy Analysis (Centraal Planbureau; Keuze in Kaart). The subsequent analysis shows that overall willingness of parties to engage in policy investments has increased during the COVID-19 crisis; suggesting that the tension between addressing short- and long-term challenges is less strict that often suggested.

From water boards to ‘climate boards’? Opportunities and threats for strategic repositioning in times of crises

Dutch water boards are commonly viewed as important player in making the Netherlands climate-proof, resonating in calls to transform water boards into ‘climate boards’. Upcoming legislative changes (i.e. the Environment and Planning Act) stress the importance of integrated approaches, emphasizing spatial quality and collaboration. Dutch water boards are therefore in a strategic repositioning process, in which the relation to the spatial planning domain stands central. The institutions’ adaptation process started already in the 1990s, yet the urgency of the current climate crisis makes it more pressing. However, strategic repositioning might be hampered due to the corona crisis. An acute crisis can absorb all attention and thereby impede a long-term transition. The question is, though, if this also applies to the water boards, as they do not have a primary responsibility in combatting Covid-19. Based on a framing analysis of strategic position papers and interviews with water board employees, we shed light on this repositioning process by identifying the water boards’ new ‘mission mystique’ and accompanying opportunities and dilemmas. We conclude that water boards remain rather cautious in living up to their new mission of a proactive partner in integrated planning; they could use their strong reputation as water authorities to act more courageous in climate-related spatial planning decisions.

Administrative craftsmanship in turbulent times

Recent events and media reporting have turned the spotlights on the role and behaviour of senior civil servants and their relationships with political office holders. In this article I ask how political-administrative interactions are perceived and enacted in the current Dutch core executive. I answer this research question by providing eight concise observations based on extensive qualitative fieldwork (300 hours) and dozens of interviews among top public servants and political executives. The observations fall into two heuristic categories: Institutional context and role and behaviour. Together, they provide an impressionistic picture how work of government elites takes shape, situated in the institutional context. These findings are particularly important as increasing media pressure and enhanced ‘publicness’ of public servants call for a stocktake of political-administrative relations and administrative behaviour. The findings have implications for both students and practitioners of public administration.
Evolution of XR Research in Brazil according to the first 22 SVR editions
Authors: Peres Fabiana F F , Teixeira João Marcelo
Published: December 2021

Although Virtual Reality technology was first developed almost sixty years ago, there has been little survey work giving an overview on how research in VR, AR and MR evolved in Brazil along with their future trends. We provide such analysis by reviewing the development made since the first WRV event, back in 1997, until SVR 2020. The first 22 event editions may help understand how the area was explored and provide a roadmap for future research. The 609 full papers analyzed were compiled into an open catalog, available on the internet. It features important filter capabilities, enabling the quick selection of papers based on citation number, conference topic, area of application, user experiments, statistical analysis and so on. We hope this tool to be of great value to the field, and also for helping researchers decide which topics should be explored when they are beginning their own studies in the area. In this analysis, we also refer to the most frequent authors in the area and how they contributed to the field based on their expertise and research group.

Published: December 2021

This empirical study yields surprising results from the connection between digitalization and the older generation. The research question explores: To what extent do seniors "want" and "can" interact with digital media? The author investigates how a digital element for the mediation of art and culture in the museum environment is accepted and perceived by senior citizens. In addition, staff members were interviewed and mediation activities were systematically observed. The data collected in this qualitative study confirms a positive reflection of the seniors, while at the same time offering clues for reducing a digital divide and increasing digital participation of seniors outside museum spaces as well.

Process Review on Dissimilar Metal Joining of Steel and Ti Alloys
Authors: You Hyeonjeong , Lee Taehyun , Kang Minjung , Kim Cheolhee
Published: December 2021

Titanium alloys have high specific strength and excellent high-temperature properties. However, Ti alloys have limited weldability with other metals due to the formation of brittle intermetallic compounds. Moreover, when steel is a counterpart of dissimilar metal joining, the soundness of weld is hardly achieved due to weld defects. Numerous studies have been conducted to achieve joint strength by minimizing the effects of Fe-Ti intermetallic compounds. In most studies, pure titanium or Ti-6Al-4V alloy were selected as the Ti base metal, whereas stainless steel, low carbon steel, or alloy steel were selected as the steel base metal. To date, joining processes such as diffusion bonding, brazing, fusion welding, and solid-state joining have been investigated. In this study, the characteristics of each of these joining processes were reviewed. More specifically, the formation of intermetallic compounds was analyzed when Ti alloy and steel were directly joined without using interlayer materials.
Microstructural Evolution of Cantilever Wire Probe after Touch-Down Fatigue Cycles for Power Semi-Conductor Wafer Testing
Authors: Hong Won Sik , Kim Mi-Song , Kim Myeongin
Published: December 2021

As fatigue fracture occurs in the bending area of the wire probe of the probe card owing to fatigue load during the touch-down (T/D) test, the development of wire probe materials with improved fatigue properties according to the wire materials is required. In this study, Tungsten (W), Rhenium-Tungsten (ReW), Beryllium-Copper (BeCu), and P7 (Palladium - Silver - Copper alloy, Pd-Ag-Cu) alloy were used to measure the tensile strength of the cantilever wire which was utilized for testing the electrical property of power semiconductor wafers used in the probe card. Additionally, the fatigue characteristics and microstructure changes of the wire were analyzed according to the T/D fatigue test using a scanning electron microscope, and electron back-scattered diffraction analysis was used for comparative analysis. In W and ReW wire probes with high initial yield strength, the misorientation angle due to grain elongation was smaller than that of P7. Accordingly, the grain deformation due to strain generation was small, whereas in materials with low initial yield strength, the misorientation angle was smaller. However, the amount of strain generated by grain orientation deformation was large. Therefore, under long-term T/D test conditions, it is assumed that ReW, W, and BeCu wire materials, which generate less deformation after long-term use than those with high initial strength, are superior to P7 materials.

Published: December 2021

Owing to global trends, automation with the fourth industrial revolution, and environmentally friendly policies owing to certified emission reduction, wire arc additive manufacturing (WAAM) is attracting attention in various industrial fields. In addition, the demands of non-ferrous metals such as aluminum and magnesium alloys are attracting attention from industries that require lightweight, large, and complex metallic parts that can be fabricated through WAAM. In this study, additive manufacturing (AM), WAAM, and current issues on the WAAM of non-ferrous metals particularly aluminum and magnesium alloys are discussed.
Dimension Precision and Uniformability Depending on the Interpass Distance Variation of Automated-Wire Arc Additive Manufacturing using 5 Cr-4 Mo Tool Steel Alloy

Published: December 2021

Die casting molds for aluminum are fabricated using machining billets of tool steels, such as Cr-Mo tool steel. However, this approach has several limitations, including significant material loss and a long lead time. Wire arc additive manufacturing (WAAM) is an alternative fabrication method that yields low material loss and has a short lead time. However, WAAM involves the repetitive stacking of layers based on designed tool paths using CAD/CAM. Thus, the predictability and uniformability of each layer are the most important factors. The interpass distance is an important parameter in a given process; however, studies on the interpass distance of the WAAM process are limited. In this study, it was determined that the interpass distance significantly influences the arc stability owing to the arc interference induced by the variation in distance from the prior deposited pass; more arc interference was observed as the interpass distance decreased. This phenomenon was validated via analysis using a high-speed camera and the variation in the amount of spatter. Furthermore, it was observed that the interpass distance influences the dimensional precision and uniformability. The interpass distance influences the arc interference unless it is greater than 100%. Thus, it is important to determine a point of balance based on the arc stability, dimension predictability, and uniformability of each layer.

Authors: Lee Jeong-Han , Park Hyun-Kuk
Published: December 2021

Spark plasma sintering method (SPS) is a new rapid sintering method developed recently for the fabrication of ceramics and composites. This method provides an advantage for sintering high-temperature materials by applying high temperature and pressure in a short time using a direct pulsed current. In this study, Binderless-WC, WC-6 wt.%Co, WC-6 wt.%Co-1 wt.% Si3N4 and WC-6 wt.%Co-2.5 wt.% Si3N4 hard materials were densified using a horizontal ball-milled WC-Co, WC-Co-Si3N4 powders, and spark plasma sintering process (SPS process). Each SPSed Binderless-WC, WC-6 wt.%Co-1 wt.% Si3N4 and WC-6 wt.%Co-2.5 wt.% Si3N4 hard materials were almost completely dense with a relative density of up to 99.2 % after the simultaneous application of a pressure of 60 MPa. The average crystallite size of WC for Binderless-WC, WC-6 wt.%Co-1 wt.% Si3N4 and WC-6 wt.%Co-2.5 wt.% Si3N4 hard materials were about 41.8, 27.4, 30.8, and 38.2 nm, respectively. Mechanical properties, microstructure, and phase analysis of SPSed Binderless-WC, WC-6 wt.%Co-1 wt.% Si3N4 and WC-6 wt.%Co-2.5 wt.% Si3N4 hard materials were investigated.
Scenarios of increasing the econo­mic efficiency of the Kaliningrad regional transport system
Authors: Gumenyuk Ivan S. , Voloshenko Ksenia Yu. , Voloshenko Ksenia Yu.
Published: December 2021

The development of the considerable transport and logistics potential of the Kaliningrad region is hampered by several factors. This problem, to which we will refer to as a transport deadlock effect, translates into the limited contribution of transport to the regional economy. Particularly, it manifests itself at the level of regional gross value added, where the contribu­tion of transport is much smaller than one might expect given the significant role the industry plays in the economy of the region. In this study, we examine major ways of increasing the economic efficiency of the regional transport system from the value added perspective. We posit that the structure of cargo handled and the redistribution of value added in favour of regional actors have the dominant influence on economic efficiency. Using our own simula­tion model and the earlier developed system of transport tariffs and value added calculation for the Kaliningrad region, we produce scenarios and consider changes in value added in the case of selected cargoes carrying intermediate, investment, and consumer goods (as defined in the International Classification for Broad Economic Categories ICT BEC-4). Our calcula­tions show that higher value added and greater economic efficiency of a regional transport system are associated with re-orientation towards investment and consumer goods. The most visible effect is associated with rail and road transport. As to sea transport, the decisive role is played by an increase in the physical volume of cargo handled. The results of this study and its modelling tools can be applied in the analysis of the current situation and in the assess­ment of the efficiency of transport systems in other regions. Another possible application is the identification of growth conditions for an industry, particularly, when developing projects and proposals for increasing the efficiency of transport services.
Contemporary relations between the state power and the armed forces from the perspective of political science
Authors: Danilović Neđo
Published: December 2021

The subject of the research in this paper are contemporary aspects of the relation between branches of the state power and the Armed Forces. The general starting hypothesis was: "If the state power holders do not have stable support in economic and political actors of the social structure and do not ensure their interaction with social, political, cultural, information and communications and security system, then the execution of the modern role of the Armed Forces in the political system is difficult." Almost all main analytical and synthetic methods of knowledge have been used in the paper, and the comparative method when it comes to general scientific methods. From the data collection methods the operational method of document content analysis has been used. The paper emphasizes several main findings, first of all, that the Armed Forces and other elements of the defence system in the process of protection of vital social values should be under constant supervision and civilian control of the legitimately elected legislative power, and the executive power should provide conditions, budget and supreme command and through ministerial instructions give guidelines and priorities for the development of the Armed Forces and directly control them. The judicial power sanctions anti-constitutional and illegal actions of the Armed Forces members, as well as other citizens of the society, but also protects the rights and freedoms of those who seek justice.

Background/Aims: Endoscopic evaluation of intraductal papillary mucinous neoplasms (IPMNs) is useful in determining whether the lesions are benign or malignant. This study aimed to examine the usefulness of peroral pancreatoscopy (POPS) in determining the prognosis of IPMNs.Methods: POPS with videoscopy was performed using the mother–baby scope technique. After surgery, computed tomography/magnetic resonance cholangiopancreatography or ultrasonography and blood tests were performed every 6 months during the follow-up.Results: A total of 39 patients with main pancreatic duct (MPD)–type IPMNs underwent POPS using a videoscope, and the protrusions in the MPD were observed in 36 patients. The sensitivity and specificity of cytology/biopsy performed at the time of POPS were 85% and 87.5%, respectively. Of 19 patients who underwent surgery, 18 (95%) patients had negative surgical margins and 1 (5%) patient had a positive margin.Conclusions: In IPMNs with dilatation of the MPD, POPS is considered effective if the lesions can be directly observed. The diagnosis of benign and malignant lesions is possible depending on the degree of lesion elevation. However, in some cases, slightly elevated lesions may increase in size during the follow-up or multiple lesions may be simultaneously present; therefore, careful follow-up is necessary.

I denne artikel præsenteres en undersøgelse af fortællinger om sprog i København skrevet af 51 københavnere. Selvom sprog sjældent behandles i forbindelse med lydhistorie, udgør mangfoldigheden af sprog i byen en central del af byens lyduniverser. Samtaler, råb og sang, for eksempel på torvet, i bussen eller i baggården, fungerer som semiotiske elementer i menneskers konstruktioner af og navigation i byens rum. Undersøgelsen konkluderer, at de københavnere, der deltog i undersøgelsen, på ingen måde oplever sprog som meningsneutrale dele af byens lydbillede. Tværtimod understreger deltagernes historier, at lyd indgår som et tegn i den altid igangværende produktion af byens mange betydninger.

Breaking away from inferiority: the strive for legitimacy in postcolonial service encounters
Authors:   , Azikiwe Evelyn
Published: December 2021

This study examines how service worker identity is mediated through global cultural flows and the consumption practices of elite clients within beauty stores in Nigeria. With a social constructionist approach and Foucault’s theoretical perspectives on power, subject and technologies of the self, I used qualitative methods involving fieldwork such as participant observation and interviews for the data collection. The findings of the study expose how inequalities that go deeper than differences in wealth and economic status shape the experiences and subject positions taken by the service workers in this context; symbolic meanings and values attached to global brands are embedded within socio-historical discourses and class differentiations; lastly, stigma is found to be a significant driver of behaviour as the workers collectively and consistently express a deep sense of inferiority in relation to their client's status, as well as relaying stories of struggle and striving for their acceptance. Thus, in seeking to manage these social asymmetries, western brands are used to mask the perceived subjugated identities experienced by the workers. The findings extend Fanon’s and Spivak’s postcolonial theoretical perspectives by examining how workers' identities are transformed through the internalization of inferiority within the context of beauty salons in Nigeria. Also, it enhances the overall theoretical perspectives of brands in the marketplace, especially in postcolonial settings like Nigeria. The implication of this study provides more insights into the socio-cultural context of global brands, which offers new business opportunities for emerging markets such as Nigeria. This is relevant because the success of most big firms from developed economies within the emerging markets is crucial, particularly as they are already operating in a saturated business environment.
Getting personal: investigating how living with universal credit affects emotions and identities
Authors:   , Negus Sophia Constance
Published: December 2021

This thesis investigates the impacts of Universal Credit (UC) on emotions, wellbeing, identities, and the ‘self’. The findings are of growing importance as increasing numbers of people are receiving UC. Six million people now engage with a ‘violent’ system (Cooper and Whyte, 2017) which pushes people further from the labour market, society, health, and their ‘self’. UC introduced radical changes to British working-age social security, with aims to ‘simplify’ the system, reduce costs and fraud, and ‘make work pay’. Since launching in 2013, there has been growing evidence on the negative impacts of UC, yet, little is known about the impact UC has on emotions, wellbeing, identities, and the ‘self’, a gap in knowledge this thesis addresses. A geographically bound case-study was adopted using semi-structured interviews and participant-solicited diaries to investigate the diverse realities and impacts of UC. The analytical framework utilises several concepts and theories, drawing upon Elias (1994) as it is argued UC is a ‘civilising offensive’ (Powell, 2013), and Goffman (1997/2007) to explore the impacts on identities. This thesis provides empirical contributions to knowledge surrounding the extent and severity of the impacts of UC on emotions and the ‘self’. The research found that harm inflicted from UC carries serious consequences and the experiences indicate a systemic erosion of people, lives, and possibilities. The findings demonstrate how UC is experienced as dehumanizing and destabilising of emotions, wellbeing and the ‘self’. It provides important insights into how people respond to UC and the significant resources spent on ‘self-management’ as individuals attempt to preserve their identities which are under threat from institutional scrutiny, stigma and increasing poverty. Therefore, this thesis provides an important contribution to knowledge surrounding the corrosive nature of UC.

Detrital zircon U-Pb geochronology of a metasomatic calc-silicate in the Tsäkkok Lens, Scandinavian Caledonides
Authors: Barnes Christopher J. , Majka Jarosław , Bukała Michał , Nääs Erika , Rousku Sabine
Published: December 2021

The Tsäkkok Lens of the Seve Nappe Complex in the Scandinavian Caledonides comprises eclogite bodies hosted within metasedimentary rocks. These rocks are thought to be derived from the outermost margin of Baltica along the periphery of the Iapetus Ocean, but detrital records from the sedimentary rocks are lacking.Many metasedimentary outcrops within the lens expose both well-foliated metapelitic rocks and massive calc-silicates. The contacts between these two lithologies are irregular and are observed to trend at all angles to the high-pressure foliation in the metapelites. Where folding is present in the metapelites, the calc-silicate rocks are also locally folded. These relationships suggest metasomatism of the metapelites during the Caledonian orogenesis. Zircon U-Pb geochronology was conducted on sixty-one zircon grains from a calc-silicate sample to investigate if they recorded the metasomatic event and to assess the detrital zircon populations. Zircon grains predominantly show oscillatory zoning, sometimes with thin, homogeneous rims that have embayed contacts with the oscillatory-zoned cores. The zircon cores yielded prominent early Stenian, Calymmian, and Statherian populations with a subordinate number of Tonian grains. The zircon rims exhibit dissolution-reprecipitation of the cores or new growth and provide ages that span similar time frames, indicating overprinting of successive tectonic events. Altogether, the zircon record of the calc-silicate suggests that the Tsäkkok Lens may be correlated to Neoproterozoic basins that are preserved in allochthonous positions within the northern extents of the Caledonian Orogen.
Selected aspects of modern seismic imaging and near-surface velocity model building in the area of Carpathian fold and thrust belt
Authors: Dalętka Andrzej Michał

Despite the increasing technological level of the reflection seismic method, the imaging of fold and thrust belts remains a demanding task, and usually leaves some questions regarding the dips, the shape of the subthrust structures or the most correct approach to velocity model building. There is no straightforward method that can provide structural representation of the near-surface geological boundaries and their velocities. The in-terpretation of refracted waves frequently remains the only available technique that may be used for this purpose, although one must be aware of its limitations which appear in the complex geological settings.
In the presented study, the analysis of velocity values obtained in the shallow part of Carpathian orogenic wedge by means of various geophysical methods was carried out. It revealed the lack of consistency between the results of 3D refraction tomography and both the sonic log and uphole velocities. For that reason, instead of the indus-try-standard utilization of tomography, a novel, geologically-consistent method of velocity model building is pro-posed. In the near-surface part, the uphole velocities are assigned to the formations, documented by the surface geologic map. Interpreted time-domain horizons, supplemented by main thrusts, are used to make the velocity field fully-compatible with the litho-stratigraphic units of the Carpathians.
The author demonstrates a retrospective overview of seismic data imaging in the area of the Polish Carpathian orogenic wedge and discusses the most recent global innovations in seismic methodology which are the key to successful hydrocarbon exploration in fold and thrust regions.

The Src tyrosine kinase controls cancer-critical protein glycosylation through Golgi to ER relocation of GALNTs enzymes. How Src induces this trafficking event is unknown. Golgi to ER transport depends on the GTP exchange factor (GEF) GBF1 and small GTPase Arf1. Here, we show that Src induces the formation of tubular transport carriers containing GALNTs. The kinase phosphorylates GBF1 on 10 tyrosine residues; two of them, Y876 and Y898, are located near the C-terminus of the Sec7 GEF domain. Their phosphorylation promotes GBF1 binding to the GTPase; molecular modeling suggests partial melting of the Sec7 domain and intramolecular rearrangement. GBF1 mutants defective for these rearrangements prevent binding, carrier formation, and GALNTs relocation, while phosphomimetic GBF1 mutants induce tubules. In sum, Src promotes GALNTs relocation by promoting GBF1 binding to Arf1. Based on residue conservation, similar regulation of GEF-Arf complexes by tyrosine phosphorylation could be a conserved and widespread mechanism.

G protein-coupled receptors (GPCRs) are among the most promising drug targets. They often form homo- and heterodimers with allosteric cross-talk between receptor entities, which contributes to fine-tuning of transmembrane signaling. Specifically controlling the activity of GPCR dimers with ligands is a good approach to clarify their physiological roles and validate them as drug targets. Here, we examined the mode of action of positive allosteric modulators (PAMs) that bind at the interface of the transmembrane domains of the heterodimeric GABAB receptor. Our site-directed mutagenesis results show that mutations of this interface impact the function of the three PAMs tested. The data support the inference that they act at the active interface between both transmembrane domains, the binding site involving residues of the TM6s of the GABAB1 and the GABAB2 subunit. Importantly, the agonist activity of these PAMs involves a key region in the central core of the GABAB2 transmembrane domain, which also controls the constitutive activity of the GABAB receptor. This region corresponds to the sodium ion binding site in class A GPCRs that controls the basal state of the receptors. Overall, these data reveal the possibility of developing allosteric compounds able to specifically modulate the activity of GPCR homo- and heterodimers by acting at their transmembrane interface.

Background/Aims: Helicobacter pylori (H. pylori) can disseminate between couples. The present study compared the findings of gastric cancer screening between seronegative subjects according to the presence of an infected spouse.Materials and Methods: Follow-up data of seronegative subjects were analyzed among married couples who underwent gastric cancer screening via gastroscopy, serum pepsinogen, and anti-H. pylori IgG assays between January 2010 and May 2016. New detection rates of H. pylori infection and gastric neoplasm at the follow-up screening were compared between seronegative subjects according to the H. pylori-infected status of spouse.Results: Among 246 seronegative subjects with an H. pylori-infected spouse, 92 underwent follow-up tests (case group). Among 278 seronegative subjects with seronegative spouse, 94 underwent follow-up tests (control group). The past infection rate was higher in the case group than in the control group (52/92 vs. 34/94; P=0.005). New H. pylori infection was diagnosed in three of the 92 cases and two of the 94 controls (3.2% vs. 2.1%; P=0.681). During the mean follow-up of 67.9±36.0 months, three adenocarcinomas and two adenomas (5/184) were newly detected among the cases and their spouses, whereas none (0/188) were detected among the controls and their spouses (2.7% vs. 0%; P=0.029).Conclusions: Gastric neoplasm occurred more frequently in couples with an H. pylori-infected spouse. Because the past infection rate is higher among seronegative subjects with an infected spouse, gastric cancer screening is recommended in both partners when the spouse is infected.
Helicobacter pylori Eradication and Gastric Cancer Prevention
Authors: Park Chan Hyuk
Published: December 2021

Since Warren and Marshall demonstrated Helicobacter pylori (H. pylori) as a cause of gastritis in the early 1980s, H. pylori has been associated with various gastric diseases, including gastric ulcer, gastric mucosa-associated lymphoid tissue (MALT) lymphoma, gastric adenoma, gastric adenocarcinoma, and hyperplastic gastric polyps. H. pylori eradication therapy can treat some associated diseases, including low-grade gastric MALT lymphoma, and significantly reduce the risk of peptic ulcer recurrence or progression of atrophic gastritis and intestinal metaplasia. In East Asia, where H. pylori and gastric cancer are prevalent, several studies have been conducted to prove whether the risk of gastric cancer development is reduced through H. pylori eradication therapy. Early studies failed to show the benefits of H. pylori eradication therapy in gastric cancer prevention. However, recent studies with extended follow-up periods have reported reduced risks of gastric cancer after treatment of H. pylori infection. H. pylori eradication therapy effectively prevents gastric cancer even in patients who were treated for early gastric cancer, and can be used in treating hyperplastic gastric polyps. Herein, we reviewed current evidence supporting the benefits of H. pylori eradication therapy to help clinicians understand its impact on gastric cancer prevention and hyperplastic polyp treatment.

Hip fractures in elderly patients are becoming a major social problem from various perspectives, including the progressive aging of global societies. The elderly have a high risk of hip fracture, even with minor injuries because of osteoporosis, while early surgical treatment may be difficult due to comorbidities and medication. In this study, significant risk factors were identified. Patients over age 70 had three times the mortality of younger patients. Greater than three pre-existing medical conditions is associated with a 25 percent mortality rate, more than twice that of healthier patients. Surgery performed on the first day of admission and beyond the fifth day was associated with a 34 percent mortality rate. Those patients operated in during days 2 through 5 had a 5.8 percent mortality rate. There was no failures related to inadequate stem or mechanical loosening. The tendency to dislocation can be clinically identifiable by major discrepancy in length, there was no failures related to inadequate stem or mechanical loosening. The tendency to dislocation can be clinically identifiable by major discrepancy in length and only 1 patient had shortening of about 2 cms post operatively which was slightly better than that of James et al (11%).
