CancerThe evidence for a relationship between vitamin B12 and cancer risk is mixed. Some evidence supports a link between increased cancer risk and higher intakes or blood concentrations of vitamin B12, some supports a link with lower intakes or concentrations, and some evidence indicates no link at all.

Some observational evidence also shows an association between supplements containing vitamin B12 and a higher risk of certain types of cancer. For example, an assessment of 77,118 participants aged 50 to 76 years in the Vitamins and Lifestyle cohort study found that use of at least 55 mcg/day supplemental vitamin B12 for an average of 10 years was associated with a 40% higher risk of lung cancer in men [60]. However, the study found no association between supplemental vitamin B12 use and cancer risk in women.

Limited clinical trial evidence supports the finding that higher vitamin B12 intakes might increase cancer risk. In an analysis of data on 2,524 participants in the B Vitamins for the Prevention of Osteoporotic Fractures trial who were treated with supplements containing 400 mcg/day folic acid and 500 mcg/day vitamin B12 for 2 to 3 years, the risk of colorectal cancer was significantly higher, at 3.4%, in the supplementation group than in the placebo group, whose rate was 2% [61]. However, high folic acid levels are potentially linked to increased risk of colorectal cancer, so the result might be due to the folic acid rather than the vitamin B12 [62]. Furthermore, the supplements had no significant effect on overall cancer risk.

Some observational evidence shows no association between high vitamin B12 concentrations or intakes and increased risk of certain cancers. For example, higher vitamin B12 intakes or serum concentrations were not associated with an increased risk of pancreatic cancer [63], breast cancer [64], or esophageal cancer or gastric cancer [65]. Clinical trials support the lack of association between higher vitamin B12 intakes and cancer risk. [66-68]. For example, a meta-analysis of 18 RCTs that included 74,498 individuals found that supplements containing B vitamins, including 20 to 2,000 mcg/day vitamin B12, had little or no effect on cancer incidence, cancer deaths, or all-cause mortality during follow-up periods of 2 to 7.3 years [68].

Finally, evidence pointing to an association between lower vitamin B12 levels and a higher cancer risk includes observational data showing a risk of gastric cancer that was 5.8 times higher in male smokers with lower vitamin B12 levels (less than 394 pg/mL [291 pmol/L]) than in those with levels higher than 591 pg/mL (436 pmol/L) [69]. Also, two meta-analyses found associations between lower vitamin B12 concentrations or intakes and a higher risk of colorectal cancer [70] and prostate cancer [71].

However, a few observational studies have found no such association [88,89]. In addition, according to a systematic review of 35 prospective cohort studies in 14,325 participants aged 47 to 101 years followed for an average of 5.4 years, the evidence does not support a role for low vitamin B12 in the development of cognitive impairment or dementia [90].

If you were previously married, you must obtain evidence of the termination of EVERY prior marriage you have had. Your evidence must be an original or certified copy of one of the following documents: FINAL legal divorce decree, death certificate, or annulment papers.

If you are applying for an IR1, CR1, or F2A visa as the spouse of a U.S. citizen or Lawful Permanent Resident and your petitioning spouse was previously married: You must obtain evidence of the termination of EVERY prior marriage your petitioning spouse has had. This evidence must be an original or certified copy of one of the following documents: FINAL legal divorce decree, death certificate, or annulment papers.

Collecting, documenting, and analyzing different types of evidence (like the ones explained below) not only helps you make the right decision in your workplace investigations, but can also keep you out of costly legal and reputational trouble.

Or, another employee has accused Morgan of stealing cash from her till. Others share that she is often late for her shift, bad-mouths the company, and is rude to customers. This character evidence suggests that she is not committed to her job and may not feel remorse for stealing from the company.

It requires a deduction of facts from other facts that can be proven and, while not considered to be strong evidence, it can be relevant in a workplace investigation, which has a different burden of proof than a criminal investigation.

This is one of the most reliable types of evidence to use in your investigation. While there are some cases where demonstrative evidence can be explained away, this is rare. Collect as many pieces as you can to strengthen your investigation and make the right final decision.

Digital evidence can be any sort of digital file from an electronic source. This includes email, text messages, instant messages, social media posts, files and documents extracted from hard drives, electronic financial transactions, audio files, and video files.

Digital evidence can be found on any server or device that stores data, including some lesser-known sources such as home video game consoles, GPS sport watches and other wearable tech, and internet-enabled devices used in home automation.

Collecting digital evidence requires a skillset not always needed for physical evidence. There are many methods for extracting digital evidence from different devices and these methods, as well as the devices on which evidence is stored, change rapidly.

Preserving digital evidence is also challenging because, unlike physical evidence, it can be altered or deleted remotely. Investigators need to be able to authenticate the evidence, and also provide documentation to prove its integrity.

To combat this challenge, when you uncover a piece of digital evidence, document it right away. Take a screenshot or screen capture video that clearly shows the time and date. That way, if the accused person deletes the item, you have proof that it was there.

Once you have your documentation record (e.g. image or recording), pop it into your case management system right away. With i-Sight, not only can you store your records right in the case file, but these actions will be added to the case action timeline so you can prove what pieces of evidence you uploaded and when.

This type of evidence can exonerate the accused person, usually the defendant in a criminal case. Prosecutors and police are required to disclose to the defendant any exculpatory evidence they find or risk having the case dismissed.

For instance, workplace violence, accidents that lead to injury or death, or extreme cases of harassment (especially sexual harassment) might require forensic evidence to be collected and analyzed to reach a conclusion.

The fact that the company would destroy a key tool of their business processes (and potential forensic evidence), coupled the the timing of the shut down, made federal investigators so suspicious they wrote a filing about it.

Without documentation of the evidence and an explanation of how you used it to reach your conclusion, you risk having your investigation challenged by management or one of the parties. Make sure your investigation report is thorough and compliant by using our free template.

As you go through your workplace investigation, try to collect as many types of evidence as you can. A weak investigation with little evidence puts you at risk of lawsuits, non-compliance fines, and distrust from your employees. The stronger the case you can build for your conclusion, the lower your chances of these negative consequences.

The map shows the share of the population that is accessing the internet for all countries of the world. Internet users are individuals who have used the Internet (from any location) in the last 3 months. The Internet can be used via a computer, mobile phone, personal digital assistant, games machine, digital TV etc.

There is evidence that in other rich countries people also spend many hours per day online. This chart shows the number of hours young people spend on the internet across a selection of rich countries. As we can see, the average for the OECD is more than 4 hours per day, and in some countries the average is above 6 hours per day. 2ff7e9595c
