What is Stage 4 Mesothelioma?

What is Stage 4 Mesothelioma?

Stage 4 Mesothelioma is the final stage of the Mesothelioma
disease. By the time a patient has entered Stage 4, the malignant mesothelioma
tumors have spread to different parts of the body, away from the origin of the
condition, in a process known as metastasis. Locations vary, but the cancer
tends to spread to organs such as the brain and spine, as well as the lymph

Stage 4 Mesothelioma is difficult to treat, as there are
limited viable treatments and patients may not be suitable for surgery because
they are often too weak for invasive procedures.

While Stage 4 Mesothelioma
more often than not results in a terminal diagnosis, because of the great advancements
in palliative care, it is possible to have a good quality of life. Many patients
are able to survive for many years after being given their prognosis. Of
course, the life expectancy varies from person to person, and a patient’s
outlook normally depends on the speed at which tumors are growing and how
responsive patients are to treatments.

What are the Symptoms of Stage 4 Mesothelioma?

When a patient reaches Stage 4, it is common for the patient
to experience symptoms such as breathlessness and severe coughing. Symptoms at
Stage 4 are not isolated to the chest cavity, and other symptoms that the
patient can suffer from include shortness of breath, tightness in the chest
area, as well as night sweats and hemoptysis (coughing up blood). Other
reported symptoms include night fevers, dysphagia and pain the abdomen as well
as prolonged fatigue.

In some cases, patients can suffer from cachexia. This is
not widely known, but is a syndrome that results in weight loss and weakness,
as well as muscle atrophy and appetite loss.

Stage 4 Mesothelioma can result in a high platelet count
(thrombocytosis) and in some cases anemia.

Have You Received a Stage 4 Diagnosis?

Here are some tips…

  • Try and get a second opinion from a dedicated mesothelioma
  • Find out if there are any clinical trials
    in your local area. Eligibility varies depending on your personal circumstances.
  • Try and exercise as much as possible and focus
    on keeping to a healthy diet. This helps with mood and can improve your quality
    of life.
  • See if there are any support groups in your area.
  • Try and seek inspiration by reading stories of
    people who are living with Mesothelioma.

For more information on Mesothelioma in general, we would recommend that you visit The Asbestos Cancer Organization.

Beware of Keyloggers – This is How Hackers Crack Accounts

Beware of Keyloggers – This is How Hackers Crack Accounts

The supposedly big hurdle for hackers when accessing accounts such as email, Facebook, online banking and so on is the password. However, the password for digital burglars seems to be no big deal anymore. Passwords can be spied out via so-called keyloggers. A keylogger is software that records the keystrokes and thus the string of the password.

The keylogging software is installed on the PC that the attacker wants to spy on. Frequently, keyloggers are also manually installed by people from the inner circle of the victim with the intent of secret surveillance.

The Keystrokes can be sent to the hacker online for example via Email. When the sent protocol is evaluated, sensitive data and passwords from platforms, banking software or e-mail accounts can get into the hacker’s hands.

Keylogger – What is Forbidden?

The software itself is not prohibited. A user can easily download a keylogger program. However, you come in conflict with the law when the software is installed on the computer without the knowledge and consent of the PC user to perform a covert spying.

A very popular keylogger program is the the software called “Wolfeye Keylogger”. In addition to recording keystrokes, the program has functions to record the screen of the PC user.

The illegal application is not a problem for data thieves. Therefore, on the official website of the Wolfeye Keylogger, the manufacturer expressly points out that the use on other computers without the consent of the owner is prohibited:

Protection against keyloggers

But how can a user protect himself from a keylogging program on the computer? As so often recommended, the use of a current antivirus tool is a must. Unfortunately, hackers also find backdoors here and manage to install the keylogging software on the computer despite virus scanners. The program code for the spy software may creep in unnoticed. The aforementioned Wolfeye Keylogger for example can be declared as an exception in the settings of the antivirus software and consequently no warning message is given during installation.

Password managers provide more security

Remedy could be a password manager. When using a suitable password manager, it is no longer necessary for the user to enter the password via the keyboard. The software recognizes which program or internet portal is being called up and automatically fills in the user name together with the password in the login window. This process cannot be detected by a keylogger.

Even if a password manager provides a little more security, the user should always create different passwords, so that in case of theft the hacker does not get to all accounts. In addition, a firewall can detect suspicious processes in the background that are displayed to the user.

Absolutely guaranteed security does not exist, even if very complex passwords are used together with a password manager. A procedure that is supposed to provide further security has proved its worth: the so-called two-factor authentication.

The two-factor authentication:

In this technique, the password (the 1st factor) is combined with a numerical code (the 2nd factor). The second factor, the code, is sent via SMS to the user’s mobile phone, for example. In order to perform a successful login, the first hurdle is to enter the complex password and the second hurdle, a code via SMS. This produces a very high level of security. Unfortunately, this methodology could not really prevail among the users. CMS such as WordPress, Drupal or Typo3 provide webmasters with plugins and modules to install two-factor authentication on the website.

Software producers strive to protect access with biometric data. Known among other things is the fingerprint with which a smartphone can be unlocked. Also on the face recognition is filed. Windows 10 already provides authentication of the face via the webcam with the software “Hello”.


Users can be more secure when using their computer by…

• Using complex passwords
• Use of a password manager
• Installing anti-virus software
• Running a firewall
• Use of two-factor authentication

Oktoberfest – The Munich Beer Festival in Numbers

Oktoberfest – The Munich Beer Festival in Numbers

Situated on massive grounds of 34.5 hectares nothing the Oktoberfest does…is small.

From 2018 data it’s recorded that over 13,000 people were employed at the event over the two weeks via carnival attractions, stall holders and food and drink services (including the 14 massive beer tents) and that an estimated 6.3 million visitors came to the Beer Festival in Munich.

Oktoberfest – The Munich Beer Festival

But to
get a real scope of the enormity of the Oktoberfest check out our list of stats

  1. Top 10 countries in terms of visitors to the event were USA, Great
    Britain, Austria, France, Switzerland, the Netherlands, Italy, Australia,
    Sweden and Belgium.
  2. Over 100000 seats were available in the 14 large tents and more than 20
    small tents.
  3. The Oktoberfest has its own Postal Office and over 500 postcard per day
    were officially sent from there.
  4. Guests drank 7.5 million litres of beer according to the Munich Brewers
  5. 101000 beer mass (Steins) were confiscated by security personnel at beer
    tent exits.
  6. Almost 300000 coffees and teas were purchased, 1.1 million units of
    water and lemonade, 43000 litres of sparkling wine and 169000 litres of
    non-alcoholic beer
  7. 550000 chickens were consumed along with 116 Oxen, 57 Calves, 44000kg of
    fish, 280000 sausages, 75000 pork knuckles, 100000kgs of salads, 200000kgs of
    bread (including pretzels)
  8. Lost property included 900 passports, 350phones, 300 keys, 460 wallets
    and so much more including a couple of dogs.

This really is a massive event and is still by far the world’s largest
beer fair or Volkfest (“people’s festival”). 
Known as the Wiesn locally, the Oktoberfest is held in the fairgrounds of
what used to be Theresa’s Meadows (Theresienwiese), just outside the city
centre of Munich and is an integral part of Bavarian culture that other cities
across the world have emulated since the first Oktoberfest took place back in

Many people who attend the Munich Oktoberfest do so with
official, well established companies many of whom offer accommodation options
to suit all budgets and Oktoberfest Tours that are
organised and cost effective.

In 2019 the Oktoberfest will operate from the famous opening ceremony
the “O’Zapft is” at midday on September 21st and run through until
11pm on Sunday the 6th of October. PROST!

Pamplona’s San Fermin – More than just a Bull Run…

Pamplona’s San Fermin – More than just a Bull Run…

The introduction of a much more family friendly fiesta in 2016 is reaping major rewards for the City Council of Pamplona with data collected from the 2018 event showed yet another year of increases in the number of people involved in the arts and activities program with more than 1.5million attending the event. As the city itself has a population of under 200,000 inhabitants this is good news for the local economy and the 2019 event is expected to once again experience growth. The largest attendances were again recorded at the massive nightly fireworks displays with an estimated 434,000 people witnessing the pyrotechnics and also at the Giants and Big Heads of Pamplona staging’s (the Comparsa de Gigantes y Cabezudos) where more than 190,000 witnessed these massive cardboard and paper mache statues, dance, walk, twirl and party in the streets of Pamplona. There are so many vibrant, exciting and participatory events at San Fermin nowadays proving it is way beyond participants remembering the event just for the Running of the Bulls.

Pamplona’s San Fermin fireworks

The municipal
campaign to raise awareness among all citizens and visitors to San Fermines in
Pamplona has been based on a more modern event with increased artistic and
cultural events, a fiesta free from sexist aggressions and crime and to instil
a more “green” basis to the entire fiesta with waste reduction and recycling
programs at the forefront.

There was, in 2018, 490 Official Acts on the Municipal
Program of San Fermines and in 2019 there are expected to be even more than
this. Naturally it would be impossible for anyone to attend all these events
and just keeping up with where all these events are located and when they are
on would prove to be a titanic task for any experienced festival goer.

Fortunately the City
Council of Pamplona have made this task much easier with the recent
introduction of an Official App for the event available on both android and iOS
and downloadable in Spanish, Basque, English and

marvellous new App will update the user accurately with:

  • The events program Check when and where events are
    taking place.
  • Giants and Big-heads. Locate the position of the “Comparsa”
    in real time.
  • What to do now? Get information on active and
    forthcoming events.
  • The “Encierro”. Do you intend to run the bulls? Get
    information on the track and be aware of the regulations and recommendations
    for runners.
  • Services. Locate all the service available to all:
    information offices, left luggage facilities, public toilets, police stations,
    first-aid posts, parking buildings, shower facilities, and much more

To ensure your full enjoyment in Pamplona for the
Festival of San Fermin and The Running of the Bulls this new App is highly recommended. There are many places
offering San Fermin Accommodation and a number of fantastic tour companies that
operate Pamplona Tours during San Fermin. If you’re planning on heading to San Fermin
this year think about downloading the awesome Official App of the City Council of Pamplona from the Google Play Store
or The Apple Store.

How Does SEO Work?

Google (аnd Bing, whiсh аlѕо роwеr Yаhоо search

Google uѕеѕ over 200 signals in scoring thеir

fосuѕ tоо muсh on individuаl ranking signals and lооk аt thе widеr goal оf
Gооglе, tо provide the bеѕt аnѕwеrѕ fоr itѕ users.

SEO, thеrеfоrе, invоlvеѕ making sure a wеbѕitе is
ассеѕѕiblе, tесhniсаllу ѕоund, uѕеѕ wоrdѕ thаt people tуре intо the ѕеаrсh

Google uѕеѕ a hyperlink based аlgоrithm (knоwn аѕ

How to Do SEO

SEO invоlvеѕ tесhniсаl аnd сrеаtivе activities
thаt аrе often grouped intо ‘Onsite SEO’ аnd ‘Offѕitе SEO’. This terminology iѕ
quite dаtеd, but it is uѕеful tо undеrѕtаnd, аѕ it splits practices thаt саn bе
performed оn a website, аnd аwау frоm a wеbѕitе.

These activities rеԛuirе
еxреrtiѕе, often from multiple individuаlѕ аѕ the skillsets rеԛuirеd
tо саrrу thеm out at a high lеvеl, аrе ԛuitе

Onѕitе SEO refers tо асtivitiеѕ оn a website to
improve оrgаniс visibility. Thiѕ lаrgеlу means optimising a website аnd соntеnt
tо imрrоvе the accessibility, rеlеvаnсу аnd experience fоr users. Some of thе
typical асtivitiеѕ inсludе –

Kеуwоrd Rеѕеаrсh – Anаlуѕing the types оf wоrdѕ аnd frequency uѕеd by рrоѕресtivе customers tо find a brands ѕеrviсеѕ оr рrоduсtѕ. Undеrѕtаnding thеir intеnt аnd a users еxресtаtiоnѕ frоm thеir ѕеаrсh.

Technical Auditing – Ensuring thе website саn be сrаwlеd аnd indexed, is соrrесtlу geo-targeted, and iѕ frее frоm errors or user еxреriеnсе barriers.

Onѕitе Oрtimiѕаtiоn – Imрrоving thе wеbѕitе ѕtruсturе, intеrnаl nаvigаtiоn, оn-раgе alignment аnd соntеnt rеlеvаnсу tо help prioritise kеу areas аnd target relevant search рhrаѕеѕ.

The аbоvе liѕt only tоuсhеѕ upon a small numbеr of
асtivitiеѕ invоlvеd in Onѕitе SEO аѕ аn overview.

Offsite SEO

Offsite SEO rеfеrѕ tо асtivitiеѕ carried оutѕidе
оf a website to imрrоvе оrgаniс visibility. Thiѕ is оftеn referred to аѕ ‘link
building’, which аimѕ tо inсrеаѕе thе numbеr оf rерutаblе linkѕ frоm оthеr
wеbѕitеѕ, as ѕеаrсh еnginеѕ use thеm аѕ a ѕсоring аѕ a vote оf truѕt.

Linkѕ frоm wеbѕitеѕ аnd раgеѕ with mоrе truѕt,
рорulаritу аnd rеlеvаnсу will pass mоrе vаluе to аnоthеr wеbѕitе, thаn аn
unknоwn, рооr wеbѕitе thаt isn’t truѕtеd bу the search engines. Sо the ԛuаlitу
оf a link iѕ thе mоѕt important ѕignаl.

Sоmе оf the tурiсаl асtivitiеѕ include –

Cоntеnt (‘Mаrkеting’) – Reputable wеbѕitеѕ link to еxсерtiоnаl соntеnt. Sо creating amazing соntеnt will hеlр attract linkѕ. Thiѕ might inсludе a hоw to guidе, a story, a visualisation or infographic with соmреlling dаtа.

Digitаl PR – PR provides rеаѕоnѕ for other websites to tаlk аnd link to a wеbѕitе. Thiѕ might bе intеrnаl nеwѕflоw, writing for external рubliсаtiоnѕ, оriginаl research or ѕtudiеѕ, еxреrt interviews, ԛuоtеѕ, рrоduсt рlасеmеnt аnd muсh mоrе.

Outrеасh & Prоmоtiоn – Thiѕ invоlvеѕ соmmuniсаting with key journalists, blоggеrѕ, influencers оr wеbmаѕtеrѕ about a brаnd, rеѕоurсе, content or PR to earn coverage аnd ultimаtеlу earn links tо a wеbѕitе.

Thеrе’ѕ obviously a huge numbеr оf reasons whу a
wеbѕitе might link tо аnоthеr and not all of thеm fit intо the саtеgоriеѕ
аbоvе. A gооd rulе оf thumb on whеthеr a link iѕ valuable iѕ tо consider the ԛuаlitу
оf rеfеrrаl trаffiс (visitors thаt might сliсk оn thе link tо viѕit your
wеbѕitе). If thе ѕitе wоn’t ѕеnd аnу viѕitоrѕ, оr thе аudiеnсе is соmрlеtеlу
unrelated аnd irrеlеvаnt, then it might nоt rеаllу be a link thаt’ѕ wоrth

It’s imроrtаnt tо rеmеmbеr Link ѕсhеmеѕ ѕuсh аѕ
buуing links, еxсhаnging linkѕ еxсеѕѕivеlу, or lоw-ԛuаlitу
dirесtоriеѕ and аrtiсlеѕ that aim tо manipulate Gооglе’ѕ rаnkingѕ, аrе against
thеir guidеlinеѕ and Gооglе can take асtiоn bу реnаliѕing a website.

Thе best and mоѕt ѕuѕtаinаblе аррrоасh to improve thе inbоund links tо a wеbѕitе is еаrning thеm, bу providing gеnuinе and соmреlling rеаѕоnѕ for websites tо сitе аnd link to thе brand аnd content fоr whо thеу are, the ѕеrviсе or product thеу рrоvidе or thе соntеnt they сrеаtе.
