The alleged PcComponentes hack affects 16 million customers. It’s another nightmare for phishing attacks

by

In Hackmanac Cybersecurity alerts reporting alleged hacks and massive data thefts around the world are frequent. One of the last notices, posted yesterdayaffects a Spanish company on the rise: PcComponentes. If confirmed, the alleged data theft would have affected a huge number of users. 16 million affected. According to these data, a cyber attacker using the alias ‘daghetiaw’ claimed to have managed to infiltrate PcComponentes. By doing so, it has obtained the data of 16.3 million customers, specifically: DNI/NIF Orders and invoices Address Contact details (phone) Credit card metadata (type, expiration date) IP address A sample that seems to confirm the hack. The author of the cyberattack wanted to demonstrate that the database he managed to obtain is legitimate, and to do so he has published a free extract of 500,000 users. That is already a very bad sign and seems to confirm that this hack and massive data theft has indeed been successful. There were already problems a year ago. An This failure exposed a database with access credentials. And everything fits. In The Computer Chapuzas They have contacted 0xBogart and obtained more information about that incident. This user actually talks about the fact that a database from August 2023 was already stolen and that then “it had 11,951,125 users, it makes sense that in 2026 they will have 16 million.” This expert had access to PcComponentes’ servers for five years, and only lost it “when they abandoned their data center for Amazon Web Services,” he indicates in the El Chapuzas Informático text. Pc Componentes has not confirmed the hack. At the moment those responsible for Pc Componentes have neither confirmed nor denied the massive data theft. At Xataka we are trying to contact the company to clarify the details. Meanwhile, those responsible have 72 hours from when the hack was discovered to notify the Spanish Data Protection Agency (AEPD). Up next: phishing attacks. This new massive data theft represents a potential nightmare for PcComponentes customers. If the hack is confirmed, all that data could be used for much more convincing phishing attacks: the more information cyber attackers have about us, the more they can “convince” us with messages that appear to be authentic and that manage to confuse us. Or phishing. There is also the danger of identity theft: the stolen data allows the creation of a “user profile” with which a cybercriminal can impersonate one person to deceive another with social engineering techniques. If the database has been leaked there is little that PcComponentes clients can do because their information will already be exposed. It has not been clear if there are passwords included for access to the company website in the massive data theft, but our recommendation is to change that access password as soon as possible. In Xataka | The leak of 16 billion passwords would be the largest in history. If it weren’t for the fact that it’s a gigantic rehash

It already affects nine autonomous communities

On November 7, the Spanish Agency for Food Safety and Nutrition issued an alert after detecting listeria in the canned chopped sold by DIA and manufactured by the Cárnicas Serrano company. Now he just expanded it to six more products in a case that is beginning to become much more complicated than expected. First of all: What products are involved? Chopped can thin slices: Sliced ​​packaging 150 g from the brand “Nuestra Alacena (DIA)” | Lot number: 252771 with expiration date 11/18/25 Truffled turkey with pistachios: Sliced ​​packaging of the “Serrano” brand. | Batch number 252771 with expiration date 11/18/2025 Turkey mortadella with olives: Sliced ​​packaging from the La tabla brand (Aldi) | Lot numbers: 252761 with expiration date 11/17/2025 and 252771 with expiration date 11/18/2025 Turkey mortadella: Sliced ​​packaging from the “La tabla (Aldi)” brand. | Lot number: 252761 with expiration date 11/17/2025 and 252771 with expiration date 11/18/2025 Chopped turkey: Sliced ​​packaging of the brand “La tabla (Aldi)” | Lot number: 252761 with expiration date 11/17/2025 and 252771 with expiration date 11/18/2025 Maxi turkey: Sliced ​​packaging of the brand “La tabla (Aldi)” | Batch number: 252761 and 252763 with expiration date 11/17/2025. Maxi York: Sliced ​​packaging of the brand “La tabla (Aldi)” | Batch number and expiration date: 252761 and 252763 with expiration date 11/17/2025. What has happened? As I said, on November 7 (and through the Coordinated System for Rapid Information Exchange), the AESAN received a alert notification of the Junta de Andalucía regarding the presence of Listeria monocytogenes in a sliced ​​chop sold at DIA Supermarkets. At the same time that the product was withdrawn, the authorities traced the origin of the outbreak to Cárnicas Serrano, based in Paterna (Valencia). That is where they verified that the company (in addition to having its own brand) manufactured white label sausages. for several supermarkets. That’s why the case has escalated so quickly. According to the information availablethe distribution has been to the autonomous communities of Andalusia, Asturias, Cantabria, Castilla-La Mancha, Castilla y León, Extremadura, Community of Madrid, Basque Country and Valencian Community, yes ok “It is not ruled out that there may be redistributions to other communities autonomous”. What is listeriosis? Listeriosis is an infection caused by listeria monocytogenes. It is an ‘opportunistic’ disease that especially affects pregnant women, newborns, the elderly and, in general, people with a compromised immune system who have eaten contaminated food. Therefore, although generally It is considered a “mild illness” (similar, in many cases, to “gastroenteritis”) in these groups of people can cause quite serious conditions (septicemia or meningitis) and has mortality rates that are between 20 and 30%. The common problem is that people with invasive listeriosis usually develop symptoms between one and four weeks after eating contaminated food (there have been cases where symptoms begin to appear up to 70 days later). This often makes it difficult to identify contaminated food. During pregnancy it can cause a mild infection for the pregnant woman but be serious for the baby. The infection usually occurs due to food poisoning but in severe cases it reaches the blood or brain, causing septicemia, meningitis or encephalitis. Like other food infections, listeriosis can cause fever and diarrhea. How dangerous is the situation? It depends on the level of consumption that the contaminated product reaches. The AESAN recommends that people who have products affected by this alert at home refrain from consuming them. And that is the basic security measure. If you have consumed any of the products from the affected batches and present symptoms compatible with listeriosis (vomiting, diarrhea or fever), it is recommended to go quickly to a health center. Actually: no surprise. In 2019, when the great listeria outbreak in Sevillewas published a study on the epidemiological situation of the disease warned about the increase in hospitalizations. Between 1997 and 2015, there were 5,696 listeriosis-related hospitalizations in Spain. An incredibly high number considering that only a few serious cases require hospitalization. But perhaps the most problematic thing is not that, but the fact that the numbers have not stopped growing in those almost 20 years. In the 1990s, listeria outbreaks were linked to cold cuts, sausages, and other similar products. Today, outbreaks are linked to dairy products, fruits, vegetables and, perhaps related to the upward trend, convenience foods. Is it a trend? Yes, and a dangerous trend: the European Food Safety Authority (EFSA) is clear that it is an emerging disease in Europe and that is underdiagnosed. The biggest problem with these infections is that it is not enough to keep the products refrigerated: in slightly contaminated foods, the listeria monocytogenes They can continue to multiply inside the refrigerator. In foods that do not need to be cooked, this is problematic and can only be solved by being especially scrupulous in production processes and food hygiene. In this sense, Zaida Herrador and her team (2019) concluded that, despite the progress, the growth of the disease indicates that “it is necessary to improve the surveillance of this disease in animals and humans” while continuing to improve its control and “the prevention of cases” (with advice to pregnant women and immunosuppressed people). Despite the interest that all this generated in 2019, the pandemic made the issue invisible and the consequences are visible.

What is it, who affects and when it comes into force

The Tax Agency has prepared a New Billing System for SMEs and Autonomousis called verifactu and is part of the Law 11/2021known as anti -arud law. Its objective is that all invoices issued in Spain meet some requirements and are verifiable by the Tax Agency. What is verifactu? Its official name is Veri*Factu, but we are going to omit the capital letters and asterisk in favor of readability. It is the name that the Tax Agency has put to the new billing regulations collected in the Royal Decree 1007/2003. It defines the requirements that must be adopted by the billing systems of companies and self -employed, so that All invoices follow a standard and are verifiable by the administration. Verifactu is not software to make invoices, but a technological system that will be integrated into the so -called SIF (Billing Computer Systems) to avoid possible fraud. Verifactu forces the SF to meet a series of technical requirements so that Each invoice issued is unalterable, safe and traceable. The verifactu system They will automatically send all invoices to the Tax Agency. This seeks to end the dual -use which allows a double accounting and hide the real sales of a company. All invoices issued with this system must carry the legend “verifiable invoice at the Electronic Headquarters of the AEAT” or “verifactu” and also will include a QR code. Who is obliged to use verifactu? Verifactu affects most companies and freelancers. Here are those who are obliged to meet this requirement: Companies: Companies Sociedad Anónima, Limitada Company, Cooperatives and any entity that is subject to the Corporation Tax. Autonomous: all, including those that pay them in the module regime. Revenue attribution regime entities: Includes communities of civil assets and societies. Foreign companies that have a branch in Spain: Although its headquarters are in another country, if the company operates in Spain lasting through an office, factory or branch, it will be obliged to use verifactu. Who is exempt from using verifactu? Although the vast majority of companies and professionals will be affected, there are some exemptions: Companies in the SII: he Immediate Information Supply It forces companies to communicate their turnover almost in real time, so the use of verifact would be redundant. Freelancers in modules or equivalence surcharge: The exemption only applies to cases where a complete invoice is not issued. If an invoice must be issued in an operation, they must use verifactu. Agrarian sector: Taxpayers who are accepted to the Special Regime of Agriculture, Livestock and Fisheries are exempt, but only in agrarian receipts (the buyer issues them). the Basque Country: It is a territory with their own tax regime and have their own system called Ticketbai. When does verifactu come into force? The verifactu system has been available since last April for those companies and freelancers that want to use it voluntarily. It will begin to be mandatory from next year Although companies will have to incorporate it much sooner than the self -employed, who have more margin. Companies: January 1, 2026. Autonomous: July 1, 2026. Companies that do not comply with the obligation to use certified software with verifactu face fines of up to 50,000 euros. For their part, software suppliers that do not meet the requirements could receive sanctions of up to 150,000 euros. How does verifactu work? Image: Tax Agency As we said above, verifactu is not a computer program as such that you can download and start using. To be able to issue invoices through this system, you have to get a SIF program that integrates it. At the moment it is not mandatory, but for developers the deadline to integrate it into their software has already defeated (it was July 1). This means that There are quite a few options that integrate it such as Quipu, Holded either Stel Order. These are the steps of the verifactu system: Invoice emission: The process does not change, the difference is that the program that is used must be certified for verifactu. Registration in the AEAT: Simultaneously, a file will be sent to the Tax Agency with the key data of the invoice. Recording records: In order to be unalterable, each new record is chained with the previous one. In this way a sequence is created that prevents modifying or erasing an invoice without breaking the complete chain. Impression and generation of QR: Also simultaneously, the invoice will be printed with a QR code and an alphanumeric identification code. What is the price of verifactu? Verifactu as such is free, but billing programs that usually have a Monthly cost. For example, Quipu has a basic plan for 14 euros per month, Holded for 14.50 euros and Stel Order offers a free plan.

A single click and goodbye to our passwords. This is the vulnerability that affects the extensions of several managers

by

We trust our Password managers as if they were digital safes. But, According to expert Marek Tóthjust visit the wrong website and click where it does not correspond to put that armor at risk. The technique presented in Def with 33 does not point to applications, but to extensions we use daily In the browser. In his tests, he ensures that this gesture can activate an information theft system without the user perceiving it. The research, made public in one of the main international conferences of computer security, documents how eleven extensions of password managers could be manipulated to filter data. Toth states that he notified the finding of manufacturers in April 2025 and that in mid -August several still still had corrections. The study includes practical tests, websites designed to demonstrate the failure and an estimate of the scope: about 40 million potentially exposed active facilities. How the attack works and why it affects you The technique described by Tóth is based on hiding the elements that the extensions insert on the page so that the user interacts with them without seeing it. With minimal changes in opacity or overlapthe attacker gets that The self -fulfilling is activated in the background. And there are several ways to achieve it, from manipulating the root element of the extension to altering the entire body of the site, in addition to variants by overlap. The most delicate scenario appears when a trap website is not necessary, but it is enough to take advantage of a legitimate page with a security failure. In those cases, he explains, the attacker can capture login credentials. The risk increases because many managers fill data not only in the original domain, but also in subdomains, which expands the attack surface without the user noticing it. According to data published by Tóth and collected by Socketon August 19, 1Password, Bitwarden, ENPASS, were continued as vulnerable Icloud PasswordsLastpass and Logmeonce. On August 20, Socket updated that Bitwarden had sent version 2025.8.0 with a patch, pending distribution in extensions. Among the managers who did apply corrective measures are NordPass, Dashlane, Keeper, Protonass and Roboform. Of course, this list can vary at any time if other companies publish arrangements after the dissemination. Extension of password manager for the browser The manufacturers reaction was disparate. Socket points out that 1Password and Lastpass classified the ruling as “informative”, a category that usually implies absence of immediate changes. Bitwarden, ENPASS and Apple (Icloud Passwords) confirmed that They work in updateswhile Logmeonce did not respond to contact attempts. Some companies admitted the existence of risk, but related to external vulnerabilities at the sites visited. While some developers decide how to act, Toth and Socket team agree that there are practical measures to reduce exposure. One of the most effective is to deactivate the manual self -fulfilling and resort to copying and paste. It is also recommended to configure the automatic filling only for exact URL coincidences, preventing it from working in subdomains. In chromium -based browsers, the use of the extension can be limited with the access option “When clicking”, so that the user explicitly authorizes each use. The researcher shows how it is possible to overlap invisible elements on the page to deceive the user and press the password manager without realizing it Not everything is as immediate as clicking and losing everything. For the attack to succeed, the extension must be unlocked, the browser has not restarted and the user interact at the right time. In addition, the analysis focused only on eleven extensions. There is no evidence that All solutions The market is vulnerable, although the expert warns that the pattern can be repeated in other types of extensions. The weak point is in the SUNthe internal structure used by websites to organize buttons, forms or menus. Password managers insert their elements there, and if a malicious page manages to move them, hide or force them, the user can end up clicking without realizing it. That same risk extends to other extensions such as cryptocurrency wallets or notes applications.

Everything to know, what each symbol means and how it affects you

by

The day came. From today, Juniode 2025, all mobile phones and tablets will have to have the energy label. Yes, that same label that we are used to seeing In every small and large house appliance. This regulation entered into force on September 20, but it has not been until now that the validity has been full. From today, if a manufacturer wants to sell its mobiles and tablets in European territory, you will have to add the label in the box. It is an interesting change and that we will begin to notice sooner rather than later in the linear of electronics and websites. Thus, we are going to review everything that needs to know about this label, what each symbol means and what the regulation on ecological design that also comes into play. What devices affects. According to Regulation (EU) 2023/1669 of the commission of June 16, 2023this new regulation will apply to mobile phones (with a tactile screen between four and seven inches), wireless landlines and tablets (with touch screen between seven and 17.4 inches). Those devices will have to have their energy EPREL energy tag (acronym for European Product Registry for Energy Labelling). Energy label that we will see from now on mobiles and tablets | Image: European Union What is the label. Virtually identical to what you can find in any appliance and similar to the one you can see on these lines. There are several symbols and their meanings are as follows: A QR code with a link provided by the manufacturer to product -related information. The commercial brand of the device. If the mobile is Samsung, “Samsung”. The identifier of the specific model. For example, the Samsung Galaxy S25 Ultra 256 GB is the SM-S938BZBDEUB. The Energy Efficiency Scale: “A” is the maximum possible score and “G” is the worst. The device efficiency level according to the anterior scale. The autonomy of the battery per cycle measured in hours and minutes per complete battery charge. That is, how much the battery lasts for the mobile. The reliability of the device in free fall: “A” is the maximum possible score and “e” is the worst. The repair of the device: “A” is the maximum possible score and “E” is the worst. Load cycles supported by the phone until the battery reaches 80% of its maximum capacity. In other words, the battery degradation rate. Classification of Water Resistance, Dust and Subsibility. For this indicator the IP certificate. The regulation number. In this case, “2023/1669“ Where will it be shown? The label must measure at least 68 x 136 millimeters, so we will probably find it in the back of the device box. However, the label must be visible in the linear and exposed products, so we will surely find it printed near the plate with the information and the price of the terminal. On the websites, the approach is the same as with the appliances: upload the label as a more product photo and adopt the reduced format for the preview. This is seen the energy labeling in appliances in Amazon (really in any ecommerce, it is something standard). From now on, when we look for a mobile we should see the same | Image: Xataka How all this is measured. The European Regulation establishes that measurements and calculations will be made using harmonized norms whose reference numbers have been published in the Official Gazette of the European Union or other reliable, precise and reproducible methods that take into account the most advanced methods generally accepted. ” While these standards arrive, other transitory test methods have been established. For example, the assigned capacity and autonomy of the battery in cycles is measured with respect to the standard IEC in 61960-3: 2017Rayado resistance based on the standard In 15771: 2010resistance to accidental falls depending on the IEC 60068-2-31, repeated free fall-Procedure 2etc. All this is detailed In Annex IV bis of the Regulation. It is not something “random” or that each brand can do as they want. Fallen tests made to a OnePlus 13 | Image: Xataka What if it is rounded? In fact, the regulation contemplates the possibility that a falsea brand the data. Annex IV establishes that manufacturers should not design their devices to change their behavior if they detect that they are being subjected to rehearsal, ergo that are being investigated. If detected, the device would not pass the certification and could not be sold at our borders. How to measure that? With common tolerances. Suppose a country decides to check if what the X brand says about autonomy per cycle is true. When doing the test, we already know that it is standard, the value obtained cannot be less than the value declared in +3%. If the brand ensures that the battery endures 60 minutes, but the test determines that it endures 50 minutes, the device does not meet the tolerances (in this case the maximum acceptable would be 58.2 minutes) and, therefore, does not comply with the regulation. All this, again, comes detailed in the document. Fairphone 5 | Image: Fairphone That the devices hold more. Another interesting aspect is that the regulation establishes a series of minimums in the call Ecological Design Regulation. This imposes on manufacturers some figures that play in favor of the consumer, who put on the table not a few challenges and that, surely, to speak in the coming months. The main points are the following: Fall resistance: Mobile will have to endure 45 falls from a meter high without a case or protector. In the case of folding, 35 closed and 15 open falls (always with the pre -installed sheet). Rayados resistance: mobile phones must have a minimum level of level four on the MOHS scale. This obviously does not apply to folding. Water and dust resistance: mobile phones, all, must be resistant to objects of more than one millimeter already thickness and water splashes. It would be the equivalent of an IP42 or … Read more

We have been seeing that Ozempic affects fertility. Now the United Kingdom has begun to take the “Ozempic Babies” seriously

by

Ozempic He began his career as a drug against diabetes but became one of the most popular medications worldwide when we realized that among its “side effects” was weight loss. Since then we have been detecting other possible effects, positive and negative but surely the most surprising of these is on its effects on fertility. Set deals with the phenomenon of the “Ozempic Babies” The United Kingdom warns. The authority responsible for regulating drugs and health products in the United Kingdom, MHRA (Medicines and Healthcare Products Regulatory Agency) warned a few days ago of a “new” side effect associated with the consumption of Ozempic, that of an increase in pregnancy probability. While this is the first time that the organism warns about the effect, the first news about this occurred More than a year ago. How it works. Ozempic is the brand with which Danish pharmaceuticals Novo Nordisk markets a diabetes treatment based on semaglutida. This compound also serves as a basis for Wegovyname under which the drug oriented to weight loss is marketed. To understand why the same compound can function as a treatment against diabetes and as a thinning we have to understand how it acts in our body. The semaglutida works as an agonist of the peptide receptors similar to glucagon-1 (LPG-1), that is, it works as an analogue of this key hormone in the digestive process. When we eat our body naturally secretes the GLP-1 hormone to transmit two messages. The first to the pancreas, so that it begins to segregate insulin with which to metabolize the sugars of the food. The second to the brain, so that this knows that we are satiated. Drugs like Zepbound and Mounjaro They act similarlyalthough the tirzepatida on which they are based works as a double analogue of LPG-1 and GIP hormones (gastric inhibitor polypeptide). Ozempic Babies. A little over a year ago, dozens of women in treatment with any of these medications They started informing of a strange phenomenon: They were becoming pregnant despite being considered infertile or despite resorting to contraceptives. This phenomenon was soon baptized as the “Ozempic Babies“,” Ozempic babies. “ How do you do it? Since the phenomenon began to document, many wondered how it was possible. There are two mechanisms (alternative or complementary) that can explain this phenomenon. The first has to do with contraceptives, specifically with oral contraceptives. One of Ozempic’s effects is that of slow down our digestionwhich in turn makes nutrients and other compounds absorb more slowly. In the preparation of an oral treatment, absorption speed is an important variable to take into account. Drugs such as contraceptives are designed for specific speeds, if these change too much, treatment can lose efficacy. He Another mechanism that could explain this phenomenon has to do with its slimming effect. As experts also highlight, there is an inverse relationship between obesity and overweight and fertility. It is possible, that by facilitating weight loss the drug is also contributing to increasing the probabilities of pregnancy. A double problem. The problem is double since it not only implies a greater probability of an unwanted pregnancy; also because this type of treatments They are contraindicated Not only for pregnant women, but also in those who seek to be. According to the recommendations, who wants to find a pregnancy should interrupt these treatments At least two months In advance to allow our body to return to normal and avoid unnecessary risks in a process as complex as gestation. Positive effects and negative effects. The “fever” by Ozempic and the drugs of its class began with a side effect: a medication aimed at treating diabetes made those who consumed it lose weight. The demand for these compounds has allowed us to find other possible Side effectspositive and negative, on which we have a greater or lesser degree of certainty. Possible adverse effects documented by the manufacturer itself can find problems such as aggravation of diabetic eye disease, potential allergic reactions and a variety of gastrointestinal symptoms, from nausea to constipation. However, since it also began to be used We have found indications on other possible effects. Some positives such as helping the fight against addictions or possible effects on renal health either cardiovascular. In the negative face we have also found indications of loss of hair and eye problems.

It affects few people, but Williams syndrome can help us understand new details about human evolution

by

Williams syndrome is a condition with its own “personality.” And it is not quite a way of speaking, some call it “personality of the Williams syndrome”And it is one of the features that usually characterize people with this uncommon condition. Let’s start at the beginning: What is Williams syndrome. The origin of this can be found in the genes of the people in which it manifests itself, specifically in chromosome seven. The absence of a region that covers between 25 and 28 genes is what causes the appearance of the syndrome. This absence can be hereditary. Although most cases are not inherited but the result of chance, who manifest this syndrome have a 50% chance of transmitting it to their descendants. This is because it is a Dominant autosomal inheritance. The syndrome affects a person between 18,000 and 7,500and does it similarly regardless of sex. According to Explain in The conversation Deborah Riby, expert from Durham University, this syndrome usually comes associated with some concrete facial features But also with problems that affect the health of those who are born with him, including heart problems and difficulties when feeding. This syndrome is usually rigged with intellectual disabilities that can be between mild and moderate, but perhaps their most defining feature, and is greater extraversion and trust. The “Williams Syndrome Personality“Includes traits, Riby explains, as the greatest sensitivity and consciousness that occurs in parallel to the difficulties that people with this syndrome present. “Many individuals are highly mad (…), some are music experts and the large majority are highly social. ‘Extroven‘,’ Over-amygible ‘, and’ emotionally sensitive ‘, are frequently used descriptions to describe (this personality), ” Riby details In your article. People with this syndrome, very often, present hyperacusia, an extreme auditory sensitivity that can be responsible for high levels of anxiety. Levels that in turn can be disabling. These features are rigged with A vulnerability related, and that is that people with the syndrome can be excessively confident, explained to the BBC Alyson Muotri, from the University of California, San Diego (UCSD). Contrary to autism? The different vision of social exchanges that characterizes people with this syndrome makes some see this syndrome as “The opposite of autism”. The idea that this disorder is an opposite to autism is also nuanceable, says Riby. “There are several cognitive domains that are problematic in both disorders. Deficits in nonverbal behavior such as visual contact, facial expressions, interpretation of gestures, are widely documented. Additionally, we know that both disorders are associated with difficulties in sensory processing, high anxieties and repetitive behaviors or restrictive interests,” Riby adds to your article. The existence of this type of relationship, both similarities and differences, lead to the possibility that learning more about one could lead us to better know the other. Especially, Riby proposes, knowing more details about this syndrome of such clear genetic origin can give us clues about the biological mechanisms that determine the appearance of something as complex as autism is. And this is not the only way in which this syndrome can help us advance in the knowledge of our own species. Some experts seek how to take advantage of this to find out new data on how they evolved as human traits, trust or sympathy. Studies on this syndrome have managed to link some of their features with the disappearance of one gene or another. Interestingly, experts They have not found the gene “Limiting sympathy” whose disappearance makes these people more extroverted and friendly.

Drinking too much affects our brain. And its effects are not far from those of a brain injury

by

We know that alcohol is a risk to our health Even in small doses. However, it is also known that the problems associated with alcoholic beverages grow significantly when we exceed the limits of what we call “moderate consumption.” Like a brain injury. A new study has observed That excessive alcohol consumption was related to the appearance of hyaline arterosclerosis, a disorder linked to brain lesions. The team highlights that, the association observed between alcohol and disorder should not be understood as proof in itself that alcohol is causing brain injuries. “Severe alcohol consumption is an important global public health problem linked to an increase in health problems and death,” pointed in a press release Alberto Fernando Oliveira Justo, co -author of the study. “We observe how alcohol affects the brain according to people age. Our research shows that excessive alcohol consumption damages the brain, which can lead to memory and cognition problems.” Hyaline artosclerosis. As explained by the study responsible for the study, the Hyaline artosclerosis It is a disorder that causes narrowing of some blood vessels, which makes them thicker and rigid. This in turn makes it difficult to flow from blood and therefore end up causing damage to the brain. This disorder can be originated in areas of the brain where there have been damaged injuries or tissue. Another disease linked to this disorder is Diabeteswhich can cause similar effects concentrated in the kidneys. From autopsies. In his study, the team responsible for the analysis had 1,781 participantsalready killed ages above 75 years. To study the impact of alcohol in their brains, cases in which brain autopsies of the bodies were used. Thus the equipment was able to look for signs of brain injuries such as TAU protein accumulations and signs of hyaline arterosclerosis. How much is a lot. The question of How much alcohol is a lot of alcohol It is difficult to answer clearly and concisely. The tolerance of our body with respect to this substance depends on factors such as our age, sex or body mass. In his study, the team conducted interviews with the relatives of the deceased people on which the study was based. From the information they classified these people among those who never drank (965 people in this group); moderate drinkers (319 participants); excess drinkers (129 people); and ex -owners who did it in excess (368 people). Finding the relationship. Once other factors were controlled, the team estimated that people in the category of excessive consumption had a risk of cerebral vascular lesions 133% higher than those who did not drink. The risk was 89% higher in the case of former owners and 60% higher in the case of those who drank moderately. The team also found indications of a relationship between alcohol consumption and the appearance of tau clusters, although this was a lower magnitude than that observed with hyaline arterosclerosis. The details of the study were published In an article In the magazine Neurology. A difficult balance. The team also observed other relationships in its study. For example cognitive problems that manifested between drinkers or a 13 -year reduction in the life expectancy of excess drinkers with respect to non -drinkers. The study represents a new test of the risks associated with alcohol. It is not rare to find information about the benefits of low gradation drinks such as wine but experts usually coincide in pointing out that, in regard to health, risks exceed possible benefits. In any case, these risks increase with consumption, something that we must also take into account.

How it affects the change from time to sleep

At two will be the three and, as a consequence of that, the dream patterns throughout Europe They will put themselves Above up. Another year. And it is logical: the day after time change, people It takes 33 minutes more than average In going to bed. In addition, they wake up 19 minutes before. That is, what does it affect us? Clear. And not only in quantitative terms; but also in qualitative term. The quality of sleep during the week following time change is frankly bad. Much worse in people between 20 and 30. These are U’s conclusionsn Analysis of sleep patterns of Samsung Health users in more than 40 countries and is interesting. Not because it is extremely representative. After all, the data starts from a huge sample selection bias: they are only its users. However, it does allow us to approach this curious phenomenon with first -hand data. Something that, until recently, was quite complicated. Samsung Health The Spanish surprise. That’s where a surprise comes to us. As I say, the analysis covers more than 40 countries around the world where the time change occurs. Of all of them, Spain is the one who showed greater stability in your sleep patterns. That is, Samsung Health users in Spain are the ones who least affected themselves in their dream for the hourly change. On average, they only delayed bedtime in 16 minutes (the country closest to us was Italy with 19) and the schedule of waking was only affected in five minutes during the first week; two during the second. Why does this happen? Well, the truth is that it is difficult to say. A possible reason may be, of course, that the Spaniards We go to bed very late. That leaves us little margin, on average, to delay the time to go to bed. However, there are other possibilities. As Jose María Olalla has defends for yearsProfessor of Physics at the University of Seville, in countries like ours “it cannot be said that (the change of seasonal schedule) is a bad idea.” Olalla explains that “at summer time it works well in summer and winter time works well in winter. Having summer time in winter is complicated, having the winter time in summer is also complicated. For different reasons, but it will always be a problem.” There are countries where change is a solution and others in which not. That is, the change of time is a simple, coordinated and fast way to adapt the schedule of the whole society to the fact that, in summer, the sun rises before. It is true that it can CAUSE DISPRUPTIONS DURING THE FIRST DAYS or weeks; But taking into account that seasonality is natural, that change would have to occur yes or yes. And the disruptions would remain in one way or another. However, we must not take it very seriously. On the one hand, we do not know how wide the sample in Spain. On the other, as well as Olalla told us“people usually do what they want, even in front of the official schedule. They do strange things, things that often collide with what theoretically is adequate.” Image | Lukas Blazek | Anthony Tran In Xataka | “Cenan at 10, they work at 9”: foreigners are understandably intrigued about how we sleep in Spain
