The Macro View – Health, Economics, and Politics and the Big Picture. What I Am Watching Here And Abroad.
September 29, 2022 Edition-----The world seems to be lurching to be overwhelmed by issues around most of the major powers being in conflict for a real risk of a global recession affecting the UK, Europe, the US and much of Asia. We seem to be in some pretty difficult times right now …In OZ Parliament is now back after the death of the Queen and it will be interesting to see how things play out and what the Budget looks like in the face of an upcoming recession.-----Major Issues.-----https://www.afr.com/politics/federal/a-nation-shorn-of-britishness-is-still-waiting-for-the-republic-20220915-p5bi90A nation shorn of Britis...

Third heart sound in health and disease
Third heart sound (S3) occurs in early diastole due to rapid deceleration of transmitral blood flow as the ventricles fill [1]. It corresponds in timing to shortly after the peak of the early diastolic E wave of transmitral flow. S3 occurs just after the opening of the atrioventricular valve as blood filling the atria during ventricular systole flows quickly into the ventricles [2].
Third heart sound can occur under physiological conditions as well as in disease, though not heard in all individuals. A prospective study of 580 patients had isolated valvular mitral regurgitation in 299, aortic regurgitation in 121 and prim...

Annulus paradoxus and annulus reversus on tissue Doppler in constrictive pericarditis
Annulus paradoxus
The term “annulus paradoxus” was proposed by Ha JW et al to indicate the inverse correlation of E/E’ to pulmonary capillary wedge pressure (PCWP) on tissue Doppler evaluation in constrictive pericarditis. Usually a positive correlation is found in patients with primary myocardial disease between E/E’ and PCWP [1]. In their study of 10 patients, E’ was not elevated despite high left ventricular filling pressures. Hence E/E’ was low, with a mean 9 and it was <15 in 9 of their 10 patients.
Another study of 130 surgically confirmed patients with constrictive pericardit...

Tei index – Myocardial performance index
Tei index – Myocardial performance index
Tei index – myocardial performance index (MPI) is the ratio of the time spent in isovolumetric activity divided by the time spent in ventricular ejection [1]. In other words, it is the sum of isovolumic contraction and relaxation times divided by the ejection time [2].
MPI = (ICT + IRT) / ET
ICT: isovolumic contraction time; IRT: isovolumic relaxation time; ET: ejection time
Myocardial performance index has an inverse relation with global ventricular function in that increasing values indicate worsening global ventricular function. There is good correlation between Doppl...

… But There Are No Cases in Turkmenistan
written by Dr. Stephen A. Berger
If you search the Internet for countries which have reported COVID-19, an endless variety of sources will describe the status of this disease in 207 countries and their dependencies. Few if any of these sites mention countries where this disease does not exist!
As of April 19, GIDEON lists twenty-four countries (10.4% of the global total) that had not yet encountered a single case. Ironically, at this point, these countries enjoy a form of “medical isolation” – thanks to the disease itself! The chance that a traveler – let alone an infected traveler – can arrive in a new coun...

Understanding Ischemic mitral regurgitation
The mechanism of MR in ischemic /Functional is complex. Technically, pure ischemic MR should have a structurally normal leaflet and the subvalvular mechanism dominates But,the combination of the two is also prevalent. In fact, a degenerative component is added to this in many elderly patients.
Mechanism of Ischemic mitral regurgitation
Any of the following may contribute either alone or in in different combinations.
Global LV dilatation with or without annular dilatation
Spherical left ventricle

Neuromyth: “Brain Training” Is Supported by Neuroscience
Online computer games promise to improve “memory, problem solving, concentration, speed of thinking, language, and visual-spatial recognition.” They further promise that they “work your social skills, social awareness, self-awareness, and self-control” while you’re having fun. These are tempting offers, and this is a very lucrative and growing business in the United States as people age and many older adults seek out ways to maintain cognitive functioning.
“Brain training” grew from $600 million in annual revenues in 2009 to more than a $1 billion in 2012 and is projected to reach $4 to $10 billion by 2020, a...

Left ventricular outflow tract gradient in hypertrophic obstructive cardiomyopathy
Left ventricular outflow tract gradient (LVOT) in hypertrophic obstructive cardiomyopathy (HOCM) is usually measured from the apical five chamber view (apical 5C) in echocardiography. Initially the apical 5C view is obtained and then the colour Doppler flow mapping (CFM) is done to locate the flow in LVOT. Continuous wave (CW) Doppler cursor is then aligned along the LVOT colour jet of HOCM. The CW jet in HOCM is described as dagger shaped or sickle shaped, unlike the symmetrical tongue ...

Adding Uzbeks to the Travel Ban Will Further Expose its Phony Criteria
Sayfullo Saipov, an Uzbek national,killed at least eight people with a truck in New York yesterday. Uzbekistan is a central Asian country north of Afghanistan ofalmost 30 million people—88 percent of whom are Muslim. President Trump did not include Uzbeks inhis travel ban released last month, but he is already sounding bellicose,writing that he will not allow ISIS to “enter our country” andthat he “ordered Homeland Security to step up our already Extreme Vetting Program,” a phrase which hesometimes uses as shorthand for the travel ban.But adding Uzbekistan to the travel ban would be unwise for a president whose...

Hypocrisy on Election Interference
In his press conference last month, President Barack Obama sternlyvoiced concern about “potential foreign influence in our election process.”The goal may be a valid one, but it cloaks hypocrisy of staggering proportions. The United States has been assiduously intervening in foreign elections for decades —perhaps even for centuries.The central issue in the 2016 election was with some hacked emails, published by Wikileaks, indicating that some top members of the Democratic National Committee were rooting for Hillary Clinton to win their party ’s nomination for president. This seems to have been the extent of the “i...

Muslims Rapidly Adopt U.S. Social Values
Concerns about Muslim assimilation made news again this week when Donald Trumperroneouslyclaimed that U.S. Muslim neighbors failed to report the San Bernardino shooters. But this persistent idea that U.S. Muslims are not assimilating could not be more inaccurate. In fact, U.S. Muslims —81 percent of whom are immigrants or children of immigrants —are the most socially liberal and religiously tolerant in the world and becoming more so with each passing year.U.S. Muslims Are Adopting Americans ’ Liberal Social and Religious ViewsMore than 80 percent of Muslim Americans are immigrants or the children of immigrants, accor...

"Their forbidden love sent them into exile in the high mountains of central Afghanistan, briefly to Tajikistan and even to jails. But more than 2 years after the young Afghan couple eloped against the wishes of their families, they arrived in New York City late last night. The couple, Zakia and Mohammad Ali, are on a 90-day visa granted by the American Embassy in Kabul and plan to apply for asylum with the help of an international aid group. When @nytimes reporter Rod Nordland first told their story 2 years ago, Zakia and Mohammad had never been alone in a room together. After they eloped, they were hunted by both their fa...
