    BBC and vitamin D

    33% reduction in hospitalization with acute respiratory infections, (upper and lower) Covid Influenza Bronchitis Pneumonia Prostate cancer, colon cancer, ovarian cancer, breast cancer, cancer treatments, dementia, diabetes type 2, metabolic syndrome, obesity, polycystic ovary syndrome, all infections, covid, TB, low mood, Alzheimer’s Parkinson’s, MSK pains and problems, osteoporosis, MS, RA, SLE, DM1, Crohn’s, psoriasis, eczema, hypertension, CAD, heart failure, stroke, preeclampsia Vitamin D deficiency linked to hospital admissions https://www.bbc.com/news/articles/czx3g1d57xpo University of Surrey People with a severe vitamin D deficiency (below 15 nmol/L), a third more likely to be admitted to hospital with conditions including bronchitis and pneumonia. (15 nmol/L is 6 ng / ml) Abi Bournot, (lead author) "antibacterial and antiviral properties" of vitamin D are thought to help reduce the risk of respiratory tract infections." Improves immune recognition Supports T and B cell response Reduces excessive pro-inflammatory cytokines Promotes production of antimicrobial peptides against bacterial infections. Enhances antiviral white cell function, e.g. promotes interferon reserves "This research attaches hard data to support the theory. "Despite its importance to our overall health, many people are deficient and do not meet the government's recommended intake of 10 microgrammes of vitamin D per day." (10 micrograms is 400 iu) NHS data from 36,258 people. (40 to 69) For each 10 nmol/l (4 ng / ml) increase in vitamin D, the hospital admission rate for respiratory tract infections fell by 4%. Association between serum 25-hydroxyvitamin D status and respiratory tract infections requiring hospital admission: unmatched case-control analysis of ethnic groups from the United Kingdom Biobank cohort https://www.sciencedirect.com/science/article/abs/pii/S0002916525007713?via%3Dihub Background Vitamin D status has been found to be inversely associated with risk of respiratory tract infections (RTIs). Methods An unmatched case-control study (Observational, cases are not individually matched on specific characteristics) Data from United Kingdom Biobank Includes 500k adults with serum 25(OH)D status and hospital episodes N = 36,258, n = 27,872 Results 34% were White 28% Asian 19% Black 11% other 7% of mixed ethnicity. RTI rate was 8.5% (median time to RTI, 14.8 y) Each 25(OH)D +10 nmol/L increase) was significantly associated with a 4% lower hazard ratio (HR) for RTI hospitalization. (So difference between 15 nmol/L and 65 nmol/L would be 50% reduction) less than15 nmol/L v more than 75 nmol/L 33% reduction in hospitalization with acute respiratory infections Learn more about your ad choices.

    Excess deaths 2025

    Excess mortality: Deaths from all causes compared to average over previous years https://bmjpublichealth.bmj.com/content/2/1/e000282 1 January 2020 until 31 December 2022 47 countries of the Western World, 3, 098, 456 Excess mortality 2021, 42 countries 2022, 43 countries Conclusions Excess mortality has remained high in the Western World for three consecutive years This raises serious concerns. Government leaders and policymakers need to thoroughly investigate underlying causes of persistent excess mortality. 2015–2019 compared to 2020–2024 Percentage difference between the reported weekly or monthly deaths in 2020–2024 and the average deaths in the same period in 2015–2019 https://ourworldindata.org/grapher/excess-mortality-p-scores-average-baseline Correlation and causality Smoking is correlated with lung cancer Asbestos exposure is correlated with mesothelioma Alcohol consumption is associated with liver cirrhosis Obesity is correlated with high sugar intake Radiation exposure is correlated with cancer Dioxin exposure is correlated with cancer Causality may be adjudicated by larger scale associations, consistent between countries, where other explanations are unlikely, where effect follows cause, where greater exposure causes more harm with a plausible biological mechanism with coherence between bench science and epidemiological data supported by (even limited) experimentation. By analogy to other causes of harm and sometimes by reversibility. https://drjohncampbell.co.uk/ Learn more about your ad choices. Visit megaphone.fm/adchoices

The expected number of deaths is based on the average number of deaths for the same week, (2015-19) This baseline could be considered a lower estimate of the expected number of deaths since both population growth and an ageing population would be expected to push up the number of deaths observed each year. For example, New Zealand saw its population grow by around 9% since 2015, with the number of people aged 65 and over increasing by 18%. Learn more about your ad choices. Visit megaphone.fm/adchoices
