Post-traumatic stress disorder (PTSD) increases the risk of cardiovascular disease and type 2 diabetes. PTSD has been found to associate with reduced cardiac contractility, cardiac ischemia, inflammation, and insulin resistance. Some lifestyle factors, including smoking, alcohol consumption, poor diet, and lack of physical activity, are believed to increase cardiometabolic disease risk in individuals with PTSD.

Dog ownership is known to improve cardiac health in the general population. Evidence suggests that dog ownership might be considered as an alternative intervention for improving PTSD condition. A large-scale study on the Swedish population found an association between dog ownership and reduced cardiovascular mortality risk over a follow-up period of 12 years.

In the current study, scientists have explored the effect of dog or cat ownership on the risk of cardiometabolic disease among US military veterans. Study design

The National Health and Resilience in Veterans Study (NHRVS), which includes multiple online surveys, was initiated in 2011 to evaluate the association between psychological health and successful aging among US military veterans. Data from the most recent cohort (2019 – 2020) of the NHRVS was used in the current study.

A total of 4,069 veterans participated in the first survey in November 2019. The second survey, which included questions about dog and cat ownership, was conducted on 3,078 veterans in November 2020. 

The presence of certain cardiometabolic diseases, including heart disease, heart attack, high cholesterol, hypertension, stroke, and diabetes, was assessed in the surveys. The presence of lifetime PTSD, major depressive disorder, alcohol use disorder, nicotine use disorder, and substance use disorder were also assessed. Regarding lifestyle factors, the weekly frequency of physical exercise was assessed.     Important observations

About 99% of survey participants responded about dog or cat ownership. Specifically, about 39% and 24% of participants responded affirmatively about dog and cat ownership, respectively.

The analysis of non-adjusted self-reported data revealed significantly lower prevalence of heart disease, high blood pressure, diabetes, and high cholesterol among dog owners compared to that among non-dog owners. However, no significant effect of cat ownership was observed on the prevalence of any cardiometabolic conditions.

Dog owners were found to be younger than non-dog owners and were more likely to be female. A higher prevalence of tested psychological disorders and addictive behaviors was observed among dog owners compared to that among non-dog owners. In addition, dog owners were found to be more physically active than non-dog owners.

The analysis of self-reported data after adjustment for age, sex, trauma load, psychological disorders, addictive behaviors, and exercise revealed that dog ownership is significantly associated with a lower risk of high blood pressure and high cholesterol.    

Considering participants’ physical exercise levels, the analysis revealed a reduction in heart disease risk with the induction of habitual exercise among dog owners. Moreover, dog owners showed a significantly lower risk of high blood pressure than non-dog owners, even with more lifetime traumatic events.

Considering the age of participants, the analysis revealed a higher risk of diabetes among dog owners over 80 years compared to age-matched non-dog owners. Similarly, a comparative higher risk of stroke was observed among dog owners aged over 70 years.

Among participants without nicotine use disorder, having a dog was found to reduce the risk of stroke. In contrast, an increased risk of stroke was observed among dog owners who had nicotine use disorder. Study significance

The study reveals that having a dog may reduce the risk of high blood pressure and high cholesterol among US military veterans. However, a negative impact of dog ownership on the risk of diabetes and stroke has been observed among older veterans and those with nicotine use disorder. Future studies are needed to establish these correlations more firmly.

Overall, the study highlights the benefits of having a dog in terms of reducing the risk of PTSD-related cardiometabolic disease. Journal reference: Woodward, S., Baldassarri, S. and Pietrzak, R.

US-Saudi relationship feels tighter than ever as Trump signs flurry of deals

In today’s Saudi Arabia, convention centres resemble palaces. 

The King Abdul Aziz International Conference Centre was built in 1999 but inside it feels like Versailles.

Some might call it kitsch, but it’s a startling reflection of how far this country has come – the growth of a nation from desert bedouins to a vastly wealthy regional powerbroker in just one generation.

Trump signs deal with Saudi Arabia

At a bar overnight, over mocktails and a shisha, I listened to one young Saudi man tell me how his family had watched this transformation.

His father, now in his 60s, had lived the change – a child born in a desert tent, an upbringing in a dusty town, his 30s as a mujahideen fighting the Soviets in Afghanistan, his 40s in a deeply conservative Riyadh and now his 60s watching, wide-eyed, the change supercharged in recent years.

The last few years’ acceleration of change is best reflected in the social transformation. Women, unveiled, can now drive. Here, make no mistake, that’s a profound leap forward.

Through a ‘western’ lens, there’s a way to go – homosexuality is illegal here. That, and the murder of Saudi journalist Jamal Khashoggi, are no longer openly discussed here.

Bluntly, political and economic expedience have moved world leaders and business leaders beyond all that.

Trump visit is ‘about opulence’

The guest list of delegates at the convention centre for the Saudi-US Investment Forum reads like a who’s who of America’s best business brains.

Signing a flurry of different deals worth about $600bn (£451bn) of inward investment from Saudi to the US – which actually only represent intentions or ‘memorandums of understanding’ at this stage – the White House said: “The deals… represent a new golden era of partnership between the United States and Saudi Arabia.

“From day one, President Trump‘s America First Trade and Investment Policy has put the American economy, the American worker, and our national security first.”

That’s the answer when curious voters in faraway America wonder what this is all about.

With opulence and extravagance, this is about a two-way investment and opportunity.

There are defence deals – the largest defence sales agreement in history, at nearly $142bn (£106bn) – tech deals, and energy deals.

Underlying it all is the expectation of diplomatic cooperation, investment to further the geopolitical strategies for both countries on key global challenges.

Trump says US will end sanctions on Syria

In the convention centre’s gold-clad corridors, outside the plenary hall, there are reminders of the history of this relationship.

There is a ‘gallery of memories’ – the American presidents with the Saudi kings – stretching back to the historic 1945 meeting between Franklin D Roosevelt and King Saud on board the USS Quincy. That laid the foundation for the relationship we now see.

Curiously, the only president missing is Barack Obama. Sources suggested to me that this was a ‘mistake’. A convenient one, maybe.

It’s no secret that the US-Saudi relationship was at its most strained during his presidency. Obama’s absence would give Trump a chuckle.

From Monday: Why does Saudi Arabia love Trump?

Today, the relationship feels tighter than ever. There is a mutual respect between the president and Saudi Crown Prince Mohammed bin Salman – Trump chose Saudi Arabia as his first foreign trip in his last presidency, and he’s done so again.

But there are differences this time. Both men are more powerful, more self-assured, and of course the region has changed.

There are huge challenges like Gaza, but the two men see big opportunities too. A deal with Iran, a new Syria, and Gulf countries that are global players.

Trump’s biggest ‘deals’ during second term so far

Trump 'thinking' of going to Turkey for proposed Zelenskyy-Putin talks - as Russia silent on attending

Donald Trump has often said that his “favourite word” is “tariff”. Surely “deal” would come a close second.

The president‘s new term in the White House has been dominated by a protectionist agenda aimed at restoring America’s domestic manufacturing base and jobs.

His primary objective is cutting America’s trade deficit – by which the country imports more in value terms, than it exports.

That gap, the largest for any country in the world, stands at about $1.1trn (£830bn) annually.

The threat of, and later, the implementation of stop-start tariffs has flung the global trade order into chaos, with some companies and traditional trading partners taking the opportunity of a “deal”, when able to.

Mr Trump has claimed that his work to date is worth $10trn (£7.5trn) to the US economy but experts have said the values are likely to be much lower and almost impossible to quantify.

Here, we outline some of the big deals to have been claimed so far in a bid to achieve Mr Trump’s economic and trade goals.

‘US is losing’ trade war

Stargate

A boost to AI infrastructure in the US was announced by the president on his first full day back in the White House.

The OpenAI-led venture, mostly funded by Japan’s Softbank, will see up to $500bn (£375bn) spent on data centres up to 2029.

It has been widely reported this week that progress has stalled, however, due to US trade tariffs.

Apple

The iPhone maker announced in February its largest ever spending commitment, of more than $500bn (£375bn) over four years.

Along with AI data centres, the company has pledged to build an “advanced” factory in Texas under Mr Trump’s push for US manufacturing growth.

Nvidia

The world’s most valuable chipmaker revealed in April that it was to invest $500bn (£375bn) in the US over four years.

The company, which makes the majority of its chips in Taiwan currently, said it was to spend the bulk of the money on domestic AI servers. Two manufacturing plants – in Arizona and Texas – will also be expanded under the plans.

Starmer defends US deal

US-UK trade deal

More of a truce than a comprehensive trade deal – and almost impossible to put a value on given the disruption to date – but this was the first “deal” that the Trump administration did to end some tariffs against a country.

It sees 25%+ duties on UK-made cars cut to 10% under a quota system that will also see steel tariffs scrapped.

However, a 10% levy remains on all other goods.

Prime Minister Sir Keir Starmer said that the partially completed agreement would save “thousands of jobs”.

US and China pause worst of trade war

US-China trade deal

The president hailed a “reset” in relations with China following a deal, revealed on 12 May, that will end the effective trade embargo between the world’s two largest economies.

US tariffs of 145% and those imposed by China, of up to 125%, had effectively killed most trade altogether but have been paused for 90 days. They have been replaced by effective rates of 30% and 10% respectively.

Saudi Arabia

Donald Trump signed a “$600bn deal” with Saudi Arabia, which includes the “largest defence sales agreement in history” on Tuesday 13 May.

He said during his visit to the kingdom that, in addition to purchases of $142bn (£107bn) of US-made military equipment, there will also be multi-billion dollar deals in Saudi Arabia with US firms including Amazon, Uber and Oracle.
