Tıp fakültesi öğrencisinden Soner Yalçın’a mektup

medikritik Pt, 25/11/2019 - 06:49

Sayın Soner
Yalçın,

Uzun
yıllardır kitaplarınızı okurum. Son çıkan “Kara Kutu” kitabınızı da tıp
fakültesi okumam sebebiyle büyük bir ilgiyle derhal alıp okumaya başladım.
Kitabın sayfalarını çevirdikçe şaşkınlık içerisine girmeye başladım.

AŞI VE OTİZM İLİŞKİSİZLİĞİ

Aşının otizm
ile ilişkili olduğunu dillendirerek vatandaşı “aşı yaparken iki kere düşünün”
diye ürkütmeniz ilginç. Keşke aşı ve otizm konusunda kitabınızda kaynak
gösterdiğiniz Wakefield’in akıbetini de araştırsaydınız.

Yıl: 1998

Yer:
İngiltere

Gastroenterolog Andrew Wakefield ve arkadaşları
Lancet’te kızamık-kızamıkçık-kabakulak (KKK) aşısı yapıldıktan 1 ay sonra 8
çocukta otizm belirtilerinin başladığını bildiriyorlar.

Wakefield, KKK aşısının bağırsak enflamasyonuna
neden olduğunu, bunun sonucunda peptitlerin önce kan dolaşımına, ardından da
beyne geçmesiyle otizmin geliştiğini ileri sürüyor.

Çeşitli ülkelerde farklı araştırmacılarca yapılan
20 epidemiyolojik çalışmada, KKK aşıları ve aşılarda kullanılan thimerosal ile
otizm arasında ilişkiyi destekleyen hiçbir veri elde edilemiyor; ileri sürülen
biyolojik mekanizmanın bilimsel bir temelinin olmadığı ortaya konuyor.

Sonraki yıllarda, Wakefield’in aşı üreticelerine
dava açan avukatlarla para ilişkisi içinde olduğu, bazı araştırmalarının bu
davalarda yer alan avukatlar tarafından finanse edildiği anlaşılıyor.

İngiltere’de Ocak 2010’da Genel Tıp Konseyi (GTK)
Wakefield’i sahtecilik, araştırma tıbbının temel ilkelerini tekrarlayarak ihlal
etme gibi başlıklarda suçlu buluyor.Şubat 2010’da Lancet dergisi makaleyi geri
çekiyor.Mayıs 2010’da GTK Wakefield’in hekimlik yetkisini iptal ediyor.

Çok değil,
30 yıl önceyi düşündüğümüzde yakınlarımızın kaç aşıyla önlenebilir ölüm, kalıcı
engellilik ya da hastalıkla boğuştuğunu, kaçının sağlıklı ve uzun bir yaşam
sürmekten mahrum kaldığını hatırlamak güç değildir. Bu hastalıklardan ne
difteri kayboldu yeryüzünden ne kızamık, ne çocuk felci ne de boğmaca. Artık bu
hastalıkları çok az görmemizin nedeni 1980’li yıllardan itibaren sürdürdüğümüz
yüksek bağışıklama oranlarıdır. Dolayısıyla aşı reddi oranları arttıkça,
bu hastalıkların yeniden ve çok üzücü bir şekilde tüm halkımızın sağlığını
tehdit edeceği açıktır. Çocuklarımızın sağlıklı yaşam hakkının en temel bileşenlerinden
biri olan aşıların yerini alabilecek alternatif bir uygulama yoktur.

Sağlık
Bakanlığı verilerine göre;

19 yıldır
Türkiye’de çocuk felci, 2004’ten bu yana difteri vakası yok.

2001’de 30
bin olan kızamık vakası 2016’da sadece 9’a indi. Aşı karşıtlığı yüzünden
2019’da tekrar 2 bin 391 vaka bilirildi.

Çünkü
aşılanmayan kişi sadece kendine değil, bulaşıcılık açısından çevresindeki
kişiler için de risk oluşturur.

Aşı karşıtlığı toplum sağlığı sorunudur.

 Toplumda aşı karşıtlığının artmasını bildiğiniz halde tarafınızı koruyucu hekimliğin direği olan aşılardan değil aşı yapmamaktan yana alarak halk sağlığı sorununa ortak oluyorsunuz. Evet, aşıları üreten ilaç endüstrisinin herkes farkında ve bundan şikayetçi. Ancak bu sorunun çözümü aşıyı reddetmek olamaz. Yerli aşı üretimiyle bu sorun çözülmelidir.

ÇÖZÜM YERLİ AŞI ÜRETİMİ

İlaç
endüstrisi ile o ilaçları kullanmayarak mı mücadele edilir? Siz ve sizinle aynı
düşünen bir grup hastanın ilaçlarınızı bırakarak bu düzene tavır(!) aldığını
düşünelim. İlerleyen zamanda hastalığınızın oluşturduğu komplikasyonlar neyle
tedavi edilecek? Yine ilaçla. Yani koskoca ilaç endüstrisine karşı kişisel bir
tavırla mücadele edilemez. Devlet düzeyinde mücadele edilir.

Çiçek
aşısını 19. Yüzyılda Avrupalılara öğreten Kurtuluş Savaşı’nın zor dönemlerinde
aşı üreten Türkiye’de, 12 Mart 1971 askeri darbesiyle tifüs aşısı üretimine ve
12 Eylül 1980 askeri darbesiyle çiçek aşısı üretimine son verildi. AB “uyum”
sürecinin ilk adımı Gümrük Birliği’ne girerek 1996’da kuduz aşısı, 1997’de BCG
aşısı ve 1998’de toptan aşı üretimine son verildi. Aşılar ülkemizde sadece
ithalat yoluyla temin edilmeye başlandı.

İlaç
endüstrisiyle ilaca ve aşıya karşı çıkarak değil, kendi aşımızı ve ilacımızı
üreterek karşı çıkabiliriz.

Hastalar popülizmin kurbanı oluyor

“Modern
Tıp”a aykırı söylemlerde bulunan doktorların ekranlara çıkarılmadığını
söylüyorsunuz. İnsaf!

Bugün en çok ekranlara çıkan doktor Canan Karatay değil mi?

Siz de kanal
kanal gezip modern tıp ve aşı karşıtlığınızı anlatmadınız mı?

Bugün
basında ve medyada en çok yer alan doktorlar sizin kitabınızda referans
gösterdiğiniz kişilerdir.

Aksine
bilimsel tezleri savunan kişiler ekranlardan esirgeniyor, hastalar popüler
söylemlerin kurbanı oluyor.

Sizin ilaç
endüstrisine kafa tutan(!) ve halkın yanında dediğiniz Canan Karatay, Ahmet
Rasit Küçükusta gibi kişilerin özel muayenehane randevusu 700 TL’den başlıyor
ve 6 aydan önce sıra gelmiyor. Acaba bu popülerlikte ekranların etkisi var
mıdır?

Sağlığın
ekonomi-politiğini incelerken bu durumu da hesaba kattınız mı?

 Bir örnek vereyim:

Çocuk acil
polikliniğinde nöbetçi olduğum bir gün içeri bebeğiyle bir anne girdi. Bebeğin
yüzü gözü şişmiş ve kızarıktı, zor nefes alıyordu. Anne ağlıyordu. Ne olduğunu
sorduğumuzda “çörekotu yağı içirdim, televizyonda söylediler.” dedi. Çocuğun
tanısı anafilaksiydi.  Anafilaksi ciddi
bir alerjik reaksiyondur. Allerjene maruz kalmanın ilk dakikaları içerisinde
vücudun bütünü etkilenir. Baş etkeni de içeriği bilinmeden alınan ölçüsüz
gıdalardır.

O çocuk
yaşıyor, ancak her gün yüzlerce çocuk denetimsiz kullanılan bitkisel ürünlere
bağlı allerji ve anafilaksi sebebiyle acillerimize geliyor.

Televizyonda
sürekli halka alternatif tıp adı altında önerilen ve internet dahil her ortamda
satışı yapılan bu ürünlerin denetimi var mı? Yok.

İlaç ve
aşıların ekonomi-politiğinden bahsedelim demişsiniz. Haklısınız, bahsedelim.

Alternatif tıp şarlatanlarının 2018 küresel pazarı yaklaşık 60 milyar dolar, 2026’da 210 milyar dolar olması bekleniyor. Aşı karşıtlığının da bir ekonomi-politiği var Soner Bey. Bugün bitkisel tedavi(!) ürünleri satan İbrahim Saraçoğlu Cumhurbaşkanı Başdanışmanlığı koltuğunda oturmaktadır.

Kitabınızda
Canan Karatay’ı cansiperane savunuyorsunuz. Tercihinizdir. Ancak şu cümlenize
anlam veremiyorum:

Gebelere
yaptığımız “şeker yükleme testi” hakkında demişsiniz ki “75-100 gram glikoz
vererek yapılan ölçümde anne karnındaki 300 gram bebek bundan nasıl
etkileniyor?”

Bu cümleyi
kurmak konuya yabancı olduğunuzu açıkça gösteriyor.

Soner Bey,
gebe bir kadın bir dilim pasta ya da tatlı yediği takdirde bile neredeyse şeker
yükleme testindeki ile aynı miktarda şeker vücuduna girmektedir. Bu şekerin
kandaki ve bebeğe geçen miktarını belirleyen şey insülin hormonudur. Karşı
çıktığınız test anne adayı ve bebek için hayati önem taşımaktadır. Gebeliğince
diyabeti kontrol altında olmayan annelerin bebekleri ciddi zararlar görüyor. Bu
zararları konuşmak ise başka bir yazı konusudur.

Karatay’ın
açıklamasından sonra şeker yükleme testi yaptırmak istemeyen bir çok gebe
kadının bebeği ciddi risk altında kalmıştır. Üstelik Karatay’ın böyle bir
açıklaması varsa, ispatlayıp neden bilim camiasına sunmuyor?

Ayrıca çok
merak ettiğim bir husus var. Siz ve Canan Karatay, neden bu konularda uzman
olan kişilerle aynı programa katılmıyorsunuz?

Türk Diyabet
Vakfı Başkanı Prof. Dr. Temel Yılmaz, Canan Karatay’ı söylediklerini tartışmak
için açıktan davet etti. Kendisi neden sağlık camiasına mensup hiç kimseyle bu
konuları tartışmadı?[1]

Bazı yanlışlar tüm doğruları götürür

Kitabınızda
“bilinçli hasta” kavramını kullanmışsınız çok doğru. Eskiden baba modeli
doktorluk esastı. Doktor tek otoriteydi, hasta her dediğini yapmak zorundaydı
ve doktorun hastaya bilgi verme zorunluluğu yoktu. Oysa şimdi arkadaş modeli
hekimliğe geçiliyor. Yani doktor hastayı bilgilendiriyor ve tedaviyi işbirliği
halinde yapıyorlar.

Türkiye’de
sağlık okuryazarlığı artırılmalı. Basın ve medyada zorunlu klipler
döndürülmeli. Hastane bekleme salonlarında sıradan TV kanalları değil, bu
klipler dönmeli. Memesinde kitle saptayan hasta göğüs hastalıklarına gelmemeli,
genel cerrahiye gideceğini bilmeli.

Tıp eğitimi
yenilenmeli, çok haklısınız. Batı’ya endeksli bir eğitim modeli ile Türk
halkına uyumlu bir sağlık hizmeti vermek ve Türk tıbbını dünyadaki gerçek
konumuna ulaştırmak oldukça zor.

Tıp
öğretiminin “hastalık yok,
hasta var” sözlerinde
anlam kazanan temel ilkesi uygulamada karşılığını bulmuyor. Sağlık sistemi
hakkındaki eleştirilerde haklısınız; fazlası var, eksiği yok.

Soner Bey, “Kara Kutu”da Modern Tıp anlayışının yanlışlarından yola çıkarak Modern Tıp’ı bütünüyle zan altında bırakma hatasına düşmüşsünüz. Hele ki aşılar hakkındaki söyledikleriniz haklı olduğunuz birçok konunun önüne geçiyor.

SONUÇ

Yukarıda
bahsettiğim yanlışları öne sürerek bireysel tavırlarla bu şartlara karşı çıkmak
daha büyük bir yanlıştır. İlaç ve aşı, tekelleşme ve kapitalizme bağlı olarak
yanlış güçlerin elinde de olabilir, ancak insanlığın en büyük mucizeleridir.
Yerli ve milli üretim atağını ilaç ve aşı alanında geliştirmek halk sağlığımız
ve ekonomimiz için yapılacak en doğru iş olacaktır.

Kabul ediyoruz, günümüzde, tıp hizmetinin son derece kâr odaklı olması, doktor hasta ilişkisinin gitgide mekanikleşmesi ve ilaç firmalarının etik olmayan uygulamaları nedeniyle insanların modern tıbba olan güvenleri azalmış durumda. Pek çok doktor muayenesi son derece kısa sürüyor ve hastalar sıklıkla geçiştirildikleri hissine kapılıyorlar. Muayene sırasında yüzlerine bile bakamayan ve bir sonraki hastaya yetişme kaygısı ile hastanın kendini ifade etmesine imkan veremeden reçete yazıp hastanın eline tutuşturan doktorlar nedeniyle hastalar kendilerini uzun uzadıya dinleyecek alternatif tıpçıları tercih ediyorlar. Benzer şekilde ciddi yan etkileri olan bilinen ilaçların bu etkilerinin tam olarak açıklanmadan hastalara verilmesi nedeniyle hastalarda hekimlerinin verdiği ilaçlara genel bir güvensizlik oluşmuş durumda.

Kitabınızda
anti-kapitalizm ile bilim düşmanlığı arasındaki farkı silikleştiriyorsunuz.
İlaç endüstrisindeki  parasal akıştan namuslu
her biliminsanı ve duyarlı hekim eleştirmelidir. Ama bunu aşılar konusunda kuşku
yaratmaya kadar götürürerek anti-kapitalizm değil, üzülerek söylemek zorundayım
bilim ve toplum düşmanlığı yapmış olursunuz.

Emin olun,
ilaç endüstrisini en çok sağlık camiasında eleştiriliyor. Ancak yerine önerilen
bir sistem olmayınca yaptığınız eleştiriler yine ilaç endüstrisini beslemekten
öte gitmiyor.

Broken spheres
Dyson died in 2020 before any of his spheres could be found — although they are just one of a dozen ideas that bear his name.
<a href=https://kra30att.cc>kra at</a>
“As a young scientist, Dyson showed that three competing quantum theories were actually the same theory — he summarily ended the competition,” said William Press, the Leslie Surginer Professor of Computer Science and Integrative Biology at the University of Texas at Austin. He was not involved in the study. “Later, he applied his genius to areas of astronomy, cosmology, the extraterrestrial realm, and also the very real problem of nuclear proliferation here on planet Earth. At the time of his death, he was recognized as a provocative and creative thinker.”

George Dyson also attested to his father’s fascination and comprehensive reach across disciplines.
https://kra30att.cc
kra30 at
“Taking advantage of a short attention span and an aversion to bureaucracy, he contributed to five fields of mathematics and eleven fields of physics, as well as to theoretical biology, engineering, operations research, literature, and public affairs,” the younger Dyson said. “Many of his ideas were controversial, with one of his guiding principles being that ‘It is better to be wrong than to be vague.’”

The approach of the researchers behind the new study could offer a more fruitful path in the search for extraterrestrial intelligence, said Tomotsugu Goto, an associate professor of astronomy at the National Tsing Hua University in Taiwan. He also was not involved with the study.

“However, contamination by circumstellar debris disks, which mimic Dyson Sphere infrared signatures, remains a concern,” he added in an email. “Authors argue that the debris disks around (dwarf stars) are rare, but the 7 candidate authors selected out of 5 million sources are also rare. Despite this, the seven candidates warrant further investigation with powerful telescopes for a more definitive evaluation.”

Water and life
<a href=https://ethereumok.io/>Ethereum Mixer</a>
Lightning is a dramatic display of electrical power, but it is also sporadic and unpredictable. Even on a volatile Earth billions of years ago, lightning may have been too infrequent to produce amino acids in quantities sufficient for life — a fact that has cast doubt on such theories in the past, Zare said.

Water spray, however, would have been more common than lightning. A more likely scenario is that mist-generated microlightning constantly zapped amino acids into existence from pools and puddles, where the molecules could accumulate and form more complex molecules, eventually leading to the evolution of life.

“Microdischarges between obviously charged water microdroplets make all the organic molecules observed previously in the Miller-Urey experiment,” Zare said. “We propose that this is a new mechanism for the prebiotic synthesis of molecules that constitute the building blocks of life.”

However, even with the new findings about microlightning, questions remain about life’s origins, he added. While some scientists support the notion of electrically charged beginnings for life’s earliest building blocks, an alternative abiogenesis hypothesis proposes that Earth’s first amino acids were cooked up around hydrothermal vents on the seafloor, produced by a combination of seawater, hydrogen-rich fluids and extreme pressure.
Yet another hypothesis suggests that organic molecules didn’t originate on Earth at all. Rather, they formed in space and were carried here by comets or fragments of asteroids, a process known as panspermia.

“We still don’t know the answer to this question,” Zare said. “But I think we’re closer to understanding something more about what could have happened.”

Though the details of life’s origins on Earth may never be fully explained, “this study provides another avenue for the formation of molecules crucial to the origin of life,” Williams said. “Water is a ubiquitous aspect of our world, giving rise to the moniker ‘Blue Marble’ to describe the Earth from space. Perhaps the falling of water, the most crucial element that sustains us, also played a greater role in the origin of life on Earth than we previously recognized.”

‘Dyson spheres’ were theorized as a way to detect alien life. Scientists say they’ve found potential evidence
<a href=https://kra31s.cc>кракен даркнет</a>
What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar panels that completely surrounds a star — harnessing all the energy it produces.

“One should expect that, within a few thousand years of its entering the stage of industrial development, any intelligent species should be found occupying an artificial biosphere which completely surrounds its parent star,” wrote Dyson in a 1960 paper in which he first explained the concept
https://kra31s.cc
kraken ссылка
If it sounds like science fiction, that’s because it is: Dyson took the idea from Olaf Stapledon’s 1937 novel “Star Maker,” and he was always open about that. The late scientist was a professor emeritus at the Institute of Advanced Study in Princeton, New Jersey.
Still, coming from a thinker who some in the scientific community say might have been worthy of a Nobel Prize early in his career, the concept took hold and the hypothetical megastructures became known as Dyson spheres, even though the physicist later clarified that they would actually consist of “a loose collection or swarm of objects traveling on independent orbits around the star.”

In his paper, Dyson also noted that Dyson spheres would give off waste heat detectable as infrared radiation, and suggested that looking for that byproduct would be a viable method for searching for extraterrestrial life. However, he added that infrared radiation by itself would not necessarily mean extraterrestrial intelligence, and that one of the strongest reasons for searching for such sources was that new types of natural astronomical objects might be discovered.

“Scientists (at the time) were largely receptive, not to the likelihood that alien civilisations would be found to exist, but that a search for waste heat would be a good place to look,” said George Dyson, a technology writer and author and the second of Dyson’s six children, via email. “Science fiction, from ‘Footfall’ to ‘Star Trek,’ took the idea and ran with it, while social critics adopted the Dyson sphere as a vehicle for questioning the wisdom of unlimited technological growth.”

Tbilisi, Georgia — Jailed journalist Mzia Amaghlobeli gets weaker every day as her hunger strike has reached three weeks in Rustavi, a town near the Georgian capital of Tbilisi, her lawyer says. Now the 49-year-old is having difficulty walking the short distance from her cell to the room where they usually meet, and human rights officials, colleagues and family fear for her life.
<a href=https://kra-22.at>kra25 at</a>
Amaghlobeli was arrested Jan. 12 during an anti-government protest in the coastal city of Batumi, one of over 40 people in custody on criminal charges from a series of demonstrations that have hit the South Caucasus nation of 3.7 million in recent months.
<a href=https://kraken25-at.net>kra20.at</a&gt;
The political turmoil follows a parliamentary election that was won by the ruling Georgian Dream party, although its opponents allege the vote was rigged.

Protests highlight battle over Georgia's future. Here's why it matters.
Its outcome pushed Georgia further into Russia's orbit of influence. Georgia aspired to join the European Union, but the party suspended accession talks with the bloc after the election.

As it sought to cement its grip on power, Georgian Dream has cracked down on freedom of assembly and expression in what the opposition says is similar to President Vladimir Putin's actions in neighboring Russia, its former imperial ruler.

“We got 53 candidates for anomalies that cannot be well explained, but can’t say that all of them are Dyson sphere candidates, because that’s not what we are specifically looking for,” said Gabriella Contardo, a postdoctoral research fellow at the International School for Advanced Studies in Trieste, Italy, who led the earlier study. She added that she plans to check the candidates against Suazo’s model to see how many tie into it.

“You need to eliminate all other hypotheses and explanations before saying that they could be a Dyson sphere,” she added. “To do so you need to also rule out that it’s not some kind of debris disk, or some kind of planetary collision, and that also pushes the science forward in other fields of astronomy — so it’s a win-win.”

Both Contardo and Suazo agree that more research is needed on the data, and that ultimately they could turn to NASA’s James Webb Space Telescope for more information, as it is powerful enough to observe the candidate stars directly. However, because of the lengthy, competitive procedures that regulate use of the telescope, securing access might take some time.
If Dyson spheres really exist, what could they be used for? “If you picture ourselves having as much energy as the sun is providing every second, we could do unheard of things,” Suazo said. “We could do interstellar travel, maybe we could even move the entire solar system to our preferred location, if we wanted.”

But don’t hold your breath, because the technology and the raw materials required to build the hypothetical structures are far beyond humanity’s grasp.

“They are so big that everything we have on Earth would not be enough to build them,” Suazo added. “Freeman Dyson said that we should dismantle Jupiter — the whole planet (for the raw materials).”

That supercolossal scale probably means that Dyson spheres, if they exist at all, are very rare.

Tbilisi, Georgia — Jailed journalist Mzia Amaghlobeli gets weaker every day as her hunger strike has reached three weeks in Rustavi, a town near the Georgian capital of Tbilisi, her lawyer says. Now the 49-year-old is having difficulty walking the short distance from her cell to the room where they usually meet, and human rights officials, colleagues and family fear for her life.

Amaghlobeli was arrested Jan. 12 during an anti-government protest in the coastal city of Batumi, one of over 40 people in custody on criminal charges from a series of demonstrations that have hit the South Caucasus nation of 3.7 million in recent months.

The political turmoil follows a parliamentary election that was won by the ruling Georgian Dream party, although its opponents allege the vote was rigged.

Protests highlight battle over Georgia's future. Here's why it matters.
Its outcome pushed Georgia further into Russia's orbit of influence. Georgia aspired to join the European Union, but the party suspended accession talks with the bloc after the election.

As it sought to cement its grip on power, Georgian Dream has cracked down on freedom of assembly and expression in what the opposition says is similar to President Vladimir Putin's actions in neighboring Russia, its former imperial ruler.
