Wide Range of Global Challenges, G-7 Ministers Hope to Seal Commitments
Italy has also irked EU and U.S. allies by becoming the first G-7 member to sign up to a contentious Chinese plan to build a Silk Road-style global trade network, the trillion-dollar Belt and Road Initiative.
Foreign ministers from the Group of Seven advanced economies were wrapping up a two-day meeting in the French seaside resort of Dinard on Saturday where they hope to seal joint commitments on a range of global challenges and lay the groundwork for August’s G-7 summit in Biarritz.
Diplomats from G-7 countries, which include the U.S., France, Canada, Japan, Germany, Italy and the U.K., walked side-by-side against the rocky Atlantic coast backdrop and in the fresh Brittany air to project a united front before a working lunch. They hope to agree on a joint statement on the fight against trafficking drugs, arms and migrants in Africa’s troubled Sahel region, fighting cybercrime and stopping sexual violence against women in conflict zones, especially in Africa.
But U.S. officials said that points of discord will also be discussed at the talks led by the host, French Foreign Minister Jean-Yves Le Drian. U.S. Deputy Secretary of State John J. Sullivan said that Washington will use the G-7 forum to galvanize support for Venezuela’s opposition leader, Juan Guaido, who the U.S. has backed to lead the country into a “democratic transformation from the failed regime” of President Nicolas Maduro.
Guaido has embarked on an international campaign to topple the socialist administration of Venezuela’s president amid deepening unrest in the country, which has been plagued by nearly a month of power outages.
Washington seems to be at odds with Italy over its stance on the crisis-hit South American country, being the sole G-7 member state to not back Guaido.
The U.S. and Canada have pursued a pro-active stance on widening support for Guaido, according to French officials. But there has already been widespread alarm after Guaido was stripped of immunity by Maduro loyalists earlier this week.
“With Juan Guaido being stripped of his immunity … we don’t want the situation to escalate,” German Foreign Minister Heiko Maas said in Dinard on Saturday.
“We are still of the opinion that free elections should take place during which Venezuelans can decide themselves who will lead the country,” he added.

Anxiety Disorder is a completely normal response to perceived threats to your wellbeing. Whether it be a driving test, difficult exam or job interview, these are all situations which can commonly be labelled as ‘stressful’.
Any stressor can lead to anxiety, which is best described as an unpleasant feeling of intense fear. Regular levels of anxiety accompanying a stressful situation is a completely normal bodily reaction, but anxiety often morphs into disorders which can be hard to overcome.
Anxiety disorders are a fact of life for many. These occur when the body’s normal response to stress becomes out of hand, and it begins to produce an anxiety response to harmless situations.
A couple of examples of anxiety disorders include:
Social anxiety disorder. This is defined by a strong anxiety triggered by social situations, particularly ones such as talking in groups, talking to unfamiliar people or giving a speech. The root fear is being judged negatively by others in social situations.
Phobias. Phobias are classified as anxiety disorders, as they consist of an extreme fear response to a particular stimuli. A common phobia is arachnophobia, extreme anxiety and fear caused by spiders.
As seen from the examples, anxiety disorders are often centred around stimuli which are not anxiety-provoking for the whole population. That is the key when it comes to disorders.
What can we do to reduce anxiety?
There are multiple common remedies for anxiety, including the following:
Therapy, such as cognitive behavioural therapy (CBT).
Mindfulness and meditation.
low carb diets can be anti-inflammatory and in some cases decreases neuro-psychiatric symptoms.
Drug-related intervention, from herbal teas and cannabidiol oil to prescription medication like Prozac..
The final bullet is the one that we will focus on in this article, as want to gauge how drugs impact anxiety levels, and the testing which has gone into this.
Natural remedies including lifestyle changes such as exercise are often suggested as remedies for mild anxiety. Therapy is often suggested if anxiety becomes a real problem in someone’s life.
There is also a sliding scale of drug-related solutions. Herbal tea could be used to cure mild anxiety, whereas somebody would be prescribed medication like Prozac if their anxiety is severe.
How are drugs used to treat anxiety?
Different medication is prescribed depending on the severity of anxiety. For example, antidepressants and SSRIs such as Prozac, Zoloft and Paxil would only be administered if a patient was suffering from chronic anxiety. In this case, the drugs act on the brain’s neural pathways to alter the way in which the neurotransmitter serotonin is used.
Alternatively, antihistamines and beta-blockers are often recommended for more mild cases of anxiety. Rather than being taken daily in order to restructure the brain’s behavior, these are usually taken when anxiety occurs or before an anxiety-producing event.
For immediate relief of more acute anxiety, benzodiazepines such as diazepam and clonazepam are usually taken. However, these often receive bad press for their side effects which can include drowsiness, irritability and a physical dependence on the drug.
How do we find out which anti-anxiety drugs are safe for human use? Ethical animal testing is often the answer.
Testing for anti-anxiety solutions, particularly in rodents
Rodents are often used in scientific experiments which aim to identify new treatments for anxiety in humans. Considering the relative similarities of key brain structures, we can observe the effects of anxiety-provoking situations on rodents to know which parts of the brain could be involved in anxiety responses.
Lezak, 2017, provides excellent discussion on the testing of rodents for anxiety-like symptoms. He describes the stimuli we provide as ‘assays’, rather than ‘models’. By definition, a model is required to have extreme detail and be thoroughly tested.
One assay commonly used for anxiety measurement in rodents is the Open Field Test. This really is a basic test, involving a box in which a rodent is placed. The box is lined with tall walls which can be set to either clear or opaque.
Typically, a rodent feeling more anxiety-like would tend to stick close to the walls of the box, and venture out into the middle very little. Conversely, a ‘happy’ rodent would be explorative, and spend time in the open space in the middle of the box. It is also possible to analyze other behaviors of the rodent such as rearing, grooming and freezing, to judge its levels of confidence in its surroundings.
A simple study into measuring the effects of drugs on rodents in an Open Field Test would be to administer a benzodiazepine and record the difference in anxiety-like behaviors. There have been studies which confirm the reduction in rodent anxiety-like behaviors after administering a benzodiazepine, but which also report other changes in behavior such as shifts in locomotor pattern.
Any unexpected or additional effects which drugs have on rodents must be seriously considered before a drug is approved for human usage.
Can drugs also contribute to anxiety negatively?
So far, we have covered the ways in which drugs can be used to treat anxiety. However, it is also true that certain drugs can worsen the symptoms of anxiety.
Substance-induced anxiety disorders are the name given to anxiety, panic and fear caused by the taking of a drug, or stopping taking a drug.
Alcohol, as well as illegal drugs such as cocaine and LSD can be responsible for substance-induced anxiety disorders. This may be because of thoughts associated with the use of the drugs: “I’m worried that I’m too dependent on this drug”, “I know that if I stop taking this drug, my anxiety levels will go through the roof”.
As well as fear caused by the drug, there are other symptoms like insomnia, memory loss and difficulty breathing which can all contribute to increased anxiety levels after taking these drugs.
Abuse of stimulants and steroids in particular will cause a pounding, irregular heartbeat and racing thoughts.
In short, misusing any type of drug can lead to substance-induced anxiety disorders. If you already suffer from anxiety, the best course of action is to consult a doctor and take the drugs recommended to you, in their recommended doses.
The power of drugs on our mental wellbeing
It is clear that drugs have the capacity to affect our mental state in both positive and negative ways. In particular, anxiety is a symptom easily influenced by psychoactive drugs.
Understanding exactly what anxiety is, as well as knowing which types of drugs fit each severity level, will go a long way to fighting this disruptive mental disorder off.
