sva Vijesti :: Svaki četvrti Hrvat pati od ‘nevidljive’ kronične bolesti, pitali smo liječnika kako prepoznati simptome By www.osijek031.com Published On :: Thu, 13 Nov 2025 19:15:00 GMT Autor: Redakcija 031 Naslov: Svaki četvrti Hrvat pati od ‘nevidljive’ kronične bolesti, pitali smo liječnika kako prepoznati simpPostano: 13.11.2025. 20:15 (GMT 1) Ne postoji jedna tableta koja će smanjiti probavne tegobe i mogućnost razvoja probavnih bolesti, kaže nam odmah prof. dr. sc. Silvio Mihaljević, specijalist gastroenterologije iz Croatia poliklinike u Osijeku. Kako navodi, stres, neredovita prehrana, hrana s puno masnoća i koncentriranih ugljikohidrata su sve redom faktori koji mogu dovesti do prolaznih probavnih tegoba, a, ako su pacijenti duže vremena izloženi nepravilnom stilu prehrane, mogu dovesti i do razvoja ozbiljnih bolesti, kao što su GERB, ulkusna bolest želuca i dvanaesnika, NASH, upalne bolesti crijeva, i slično. Učestalost ovih problema pritom je sve veća. Primjerice, više od pola milijuna ljudi u Ujedinjenom Kraljevstvu ima upalnu bolest crijeva, od kojih su dva glavna oblika Crohnova bolest i ulcerozni kolitis. One nastaju kada imunološki sustav napadne crijeva, uzrokujući niz iscrpljujućih simptoma od bolova u trbuhu i gubitka težine do proljeva i krvi u stolici. Vrlo često se gore navedene bolesti razvijaju tijekom dužeg vremenskog razdoblja s vrlo nespecifičnim tegobama u samom početku bolesti. Upravo je zato izuzetno važno obratiti pažnju na preventivne preglede, kaže prof. dr. sc. Mihaljević, jer postavljanje dijagnoze u ranoj fazi bolesti značajno doprinosi kraćem trajanju liječenja, manjom mogućnošću za razvojem brojnih komplikacija, a samim time i boljom kvalitetom života i puno kraćim izostankom s posla. Uzmimo za primjer samo nealkoholnu bolest masne jetre, jednu od najčešćih uzroka kronične bolesti jetre te najbrže rastuće bolesti probavnog sustava. Prema posljednjim podacima, svaki četvrti građanin Hrvatske ima nealkoholnu masnu jetru kao posljedicu nezdrave prehrane, konzumacije alkohola i nekretanja. Prof. dr. sc. Mihaljević navodi stoga da je iznimno bitna redovita kontrola laboratorijskih nalaza koji ukazuju na funkciju jetre jer kronične bolesti nemaju značajnije probavne tegobe, nego samo blage i nespecifične smetnje kao brzo umaranje i opća slabost. “Te nespecifične simptome pacijenti ignoriraju tako da se vrlo često brojne kronične bolesti jetre pronađu u poodmakloj fazi kada je liječenje manje uspješno. Zbog svega navedenog redovite kontrole jetrenih nalaza su najbitnije u ranom otkrivanju kroničnih bolesti jetre”, kaže specijalist gastroenterologije. Kako bi potaknula građane na preventivnu brigu o zdravlju, Croatia Poliklinika u Osijeku do kraja studenog omogućuje 20 posto popusta na endoskopske zahvate - gastroskopiju bez i s anestezijom i kolonoskopiju bez ili s anestezijom. Naime, osobe koje u anamnezi imaju rak nekog od organa probavnog sustava trebali bi u ranijoj životnoj dobi obavljati preventivne preglede svake dvije godine, a osobe starije životne dobi jednom godišnje. Brojni ljudi pritom odgađaju ranije spomenute endoskopske zahvate zbog neugodnosti ili straha, zbog čega prof. dr. sc. Mihaljević ističe da je važno pacijentima objasniti važnost obje pretrage jer se promjene koje se nađu tim pretragama vrlo često ne mogu dokazati nikakvim drugim laboratorijskim i radiološkim pretragama. “Kada im se objasni važnost navedenih pregleda te mogućnost dokumentiranja određenih promjena puno lakše će se odlučiti za navedene preglede. Prije gastroskopije možemo lokalno dati anestetik koji će u znatnoj mjeri umanjiti neugodnost samog pregleda, a prije kolonoskopije savjetujem uzimanje pola sata prije pregleda spazmolitika kako bi usporili peristaltiku crijeva i na taj način umanjili tegobe. Za one najzahtjevnije i najkompliciranije, oba pregleda možemo raditi u općoj anesteziji”, navodi prof. dr. sc. Mihaljević. [Sponzorirani članak] Full Article

sva Tsvangirai Leaves an Important Political Legacy in Southern Africa By www.chathamhouse.org Published On :: Wed, 21 Feb 2018 15:14:48 +0000 Tsvangirai Leaves an Important Political Legacy in Southern Africa Expert comment sysadmin 21 February 2018 The story of Zimbabwe’s ‘people’s champion’ offers a powerful example to a region in need of new political compromises. — Supporters hold up a poster of Morgan Tsvangirai during a memorial service in Harare. Photo: Getty Images. The death of Movement for Democratic Change (MDC) leader Morgan Tsvangirai is a loss for Zimbabwe. In nearly three decades of speaking truth to power, Tsvangirai helped to change his nation and the region. Southern Africa’s new politics His death marks a period of transition for regional governments and opposition parties alike. The Zuma era has ended in South Africa while Mozambique, Namibia and Angola have also seen political transitions, pushing modernization agendas to appeal to young citizenries that increasingly see politics in separate terms from the liberationist struggles of the previous generation. Regional opposition movements also face winds of change: the longstanding opposition leader in the Democratic Republic of the Congo, Etienne Tshekedi, passed away in 2017, and Mozambique’s Afonso Dhlakama and Kenya’s Raila Odinga are both aging. These movements similarly need to appeal to a younger audience or risk losing relevance. From trade unionist to opposition leader Tsvangirai’s career is an eloquent illustration of these challenges. Born in Buhera in rural eastern Zimbabwe, Tsvangirai worked in textiles and mining before politics – diverse experience which gave him crucial exposure to the lives of ordinary people across the country. In his early years, he also worked for ZANU-PF, before leaving to forge his own political path. He became increasingly active in mining politics, rising to the executive of the National Mineworker’s Union and, in 1989, to secretary-general of the powerful Zimbabwe Congress of Trade Unions. In the late 1990’s, Zimbabwe was riven by questions over land, war veterans, the Congo conflict, a shrinking economy and growing doubts about ZANU-PF itself. Opposition leaders of the time could not answer them; those such as Edgar Tekere and Margaret Dongo struggled to win support beyond their local constituencies, and liberation leader Joshua Nkomo’s ZAPU had been merged with ZANU-PF in the 1987 Unity Accord. But in 2000, Zimbabwe’s ‘perfect storm’ of a divisive constitutional referendum, land redistribution and a June election made Tsvangirai and the newly minted MDC, formed in 1999, a national rival to ZANU-PF. Through subsequent national elections in 2002, 2005, 2008 and 2013, Zimbabwe remained polarized between competing visions of Zimbabwe future: ZANU-PF’s powerful black liberationist politics of identity and the opposition’s equally compelling liberal democracy agenda. Tsvangirai’s achievement was to provide a credible alternative to liberation icon Robert Mugabe. Tsvangirai also resuscitated Zimbabwe’s tradition of urban nationalism, and was a successor to Benjamin Burombo and other mid-century Zimbabwean urban leaders. Tsvangirai would in turn be a touchstone for contemporary urban activists Evans Mawarire, Linda Masarira and others. From opposition to coalition The political struggle for Zimbabwe became global, with Mugabe and Tsvangirai both winning support from rival international power blocs. In March 2007, pictures of a beaten and bloodied Tsvangirai helped to galvanize support for the MDC in the 2008 elections. But the disputed result and violent subsequent run-off between Tsvangirai and Mugabe led the regional community to push both men into a coalition government, with Tsvangirai as prime minister. Despite continuous ructions, the Government of National Unity (GNU) held, and stabilized Zimbabwe’s collapsed economy, until 2013. Although often politically out-manoeuvred by Mugabe, Tsvangirai deserves credit for getting the opposition a share of political power and for holding his nerve against many who wanted to collapse the GNU. Tsvangirai was no saint; his complicated love life, and tacit approval of violent attacks on party dissenters, do him no credit. More importantly, the MDC neglected its grassroots supporters during the GNU, and paid the price in its comprehensive 2013 electoral defeat. But although diminished, Tsvangirai remained Zimbabwe’s most popular opposition politician, and the MDC’s new leaders will have quite a task ahead of them, even if they have been planning since his courageous 2016 public admission of colon cancer. The MDC after Tsvangirai Nelson Chamisa, one of the three MDC vice presidents, has now been appointed as acting president by the party’s national committee. Chamisa inherits a fractured and fractious party, and one which has also fallen out with the Tsvangirai family. The other two vice presidents, Thokozani Khupe and Elias Mudzuri, have also set their sights on party leadership. At 40, Chamisa, an orator with grassroots appeal, has a huge task. With general elections due by July, he has to unite the party, counter Zimbabwe’s rising ethno-politics, prove himself as leader of a broader opposition coalition and take on a resurgent President Emmerson Mnangagwa and ZANU-PF. Electorally, the opposition’s strongest card has always been the urban vote and the economy. But Mnangagwa has fast forwarded a comprehensive economic reform and internationalist agenda. This, and Mugabe’s exit, have forced Chamisa, Joice Mujuru and other opposition leaders to play catch-up. Zimbabwe’s elections, the first since 2000 without Mugabe and Tsvangirai as contenders, will be of global interest as the country navigates the new political dynamics. The people’s champion Morgan Tsvangirai’s resilience earned him respect from friends and foes alike, with Zimbabwe’s President Mnangagwa and Vice President Constantino Chiwenga visiting him at home a few weeks ago. A former nominee for the Nobel Peace Prize, Tsvangirai, popularly known by his totem of ‘Save’ and also called mudhara [the old man] deserves national hero status. He will certainly be remembered as the ‘people’s champion’, and a pioneer in bridging the generational and ideological fissures that have shaped Southern Africa’s politics. With their leader now gone, the turbulent MDC will undoubtedly be hoping for a ‘remembrance vote’ in his memory to carry them through the elections. But beyond that, his story offers a powerful example to a region in need of new political compromises. Full Article

sva Is there a single surge mechanism? Contrasts in dynamics between glacier surges in Svalbard and other regions By hdl.handle.net Published On :: 2003-01-01T00:00:00Z Is there a single surge mechanism? Contrasts in dynamics between glacier surges in Svalbard and other regions Murray, Tavi; Strozzi, Tazio; Luckman, Adrian; Jiskoot, Hester; Christakos, Panos During the 1990s, Monacobreen, a 40-km-long tidewater glacier in Svalbard, underwent a major surge. We mapped the surge dynamics using ERS synthetic aperture radar images, differential dual-azimuth interferometry and intensity correlation tracking. A series of 11 three-dimensional (3-D) velocity maps covering the period 1991–1997 show a months-long initiation and years-long termination to the surge, with no indication of a surge front travelling downglacier. During the surge, the front of the glacier advanced 2 km, the velocity and derived strain rate increased by more than an order of magnitude, and maximum ice flow rates measured during 1994 were 5md 1. The spatial pattern of both velocity and strain rate was remarkably consistent and must therefore be controlled by spatially fixed processes operating at the glacier bed. We combine these results with those published in the literature to construct a typical Svalbard glacier surge cycle and compare this to surge dynamics of glaciers from other cluster regions, especially those of Variegated Glacier in Alaska. The strong contrast in dynamics suggests that there exist at least two distinct surge mechanisms. Sherpa Romeo green journal. Permission to archive final published version. Full Article
sva Late surge glacial conditions on Bakaninbreen, Svalbard, and implications for surge termination By hdl.handle.net Published On :: 2002-01-01T00:00:00Z Late surge glacial conditions on Bakaninbreen, Svalbard, and implications for surge termination Smith, A. M.; Murray, Tavi; Davison, B. M.; Clough, A. F.; Woodward, J.; Jiskoot, Hester Bakaninbreen is a polythermal glacier in southern Spitsbergen, Svalbard, that last surged between 1985 and 1995. Seismic reflection data were acquired during early quiescence in spring 1998, just upstream of the surge front. The results were combined with complementary ground-penetrating radar data to investigate the glacial structure and basal conditions. We find no difference between the ice thickness values determined from the seismic and radar methods, suggesting that any layer of basal ice cannot be greater than 5 m thick. Interpretation of the amplitude of the seismic reflections indicates the presence of permafrost close to the glacier base. A thin layer of thawed deforming sediment separates the glacier from this underlying permafrost. In an area just upstream of the surge front the permafrost becomes discontinuous and may even be absent, the ice being underlain by 10–15 m of thawed sediments overlying deeper bedrock. Highpressure water is believed to have been required to maintain the propagation of the surge, and this area of thawed sediment is interpreted as a route for that water to escape from the basal system. When the surge front passed over this thawed bed, the escaping water reduced the pressure in the subglacial hydraulic system, initiating the termination of the surge. Surge termination was therefore primarily controlled by the presurge permafrost distribution beneath the glacier, rather than any feature of the surge itself. This termination mechanism is probably limited to surges in polythermal glaciers, but the techniques used may have wider glaciological applications. Sherpa Romeo green journal.
