Vaccination against HPV does not increase the risk of autoneural neurodefunction syndrome in women Doi: https://doi.org/10.1136/bmj.m2930 Researchers recently assessed the risk of autoneuric neurodefunction syndrome associated with the 4-price HPV vaccine, including chronic fatigue syndrome, complex area pain syndrome, and erect TPD syndrome.
The study, a population-based self-controlled case study, was conducted in Denmark and involved 869 female participants aged 10-44 with autologic neuro dysfunction syndrome in 2007-16.
of the study was the difference in the incidence of autologic neurodefurction syndrome between HPV vaccination and non-vaccinated populations.
a total of 869 patients with autologic neurodefunctional disorder syndrome were diagnosed during the follow-up year of 1058,1902 people, of whom 136 were chronic fatigue syndrome, 535 were complex regional pain syndrome and 198 were positional erect TSD syndrome.
In the 365 days after the four-price HPV vaccination, there was no significant increase in the risk of all autologic neurodefurction syndrome (ratio 0.99) or specific syndrome risk (chronic fatigue syndrome risk ratio of 0.38; complex area pain syndrome risk ratio of 1.31; and risk of erective TPD 0.86).
.2. Female hair dye use and tumor risk assessment doi: https://doi.org/10.1136/bmj.m2942 Researchers recently assessed the relationship between hair dye use and tumor risk and mortality.
Nurses' Health Study included 117,200 female participants who reported no tumors at baseline examination and followed up for 36 years, with no significant increase in risk of solid cancer other than melanoma skin cancer in participants who never used hair dye (n-20805, with a risk ratio of 0.98) or blood system tumors (n-1807; 1.00).
In addition, the risk of death from most specific tumors in people who have used hair dyes (including skin squamous cell carcinoma, bladder cancer, melanoma, estrogen-positive breast cancer, progesterone-positive breast cancer, hormone-positive breast cancer, brain cancer, colorectal cancer, kidney cancer, lung cancer and most blood cancers) or cancer-related deaths (n=4860;0.96) has not been significantly increased.
found a slight increase in the risk of substrate cell carcinoma in people who had used it (n=22560;1.05).
is also of concern that the cumulative dose of hair dyes is associated with increased risk of estrogen-negative breast cancer, progesterone-negative breast cancer, hormone-neutral breast cancer and ovarian cancer.
the risk of specific tumors associated with hair dyes was race-related, with an increased risk of Hodgkin's lymphoma after hair dyeing in women with natural black hair (70 female patients, 24 of whom were natural brunettes), while in natural light hair color, the risk of substrate cell carcinoma was higher after hair dyeing.
.3: Workplace sexual harassment increases the risk of suicide among victims: https://doi.org/10.1136/bmj.m2984 Researchers recently assessed the risk of suicide and suicide attempts caused by sexual harassment in the workplace.
The prospective cohort study, conducted in Sweden and involving 86,451 participants in different occupations, was conducted between 1995 and 2013 in a self-survey on work-related sexual harassment, with the main endpoints of the study being suicide and suicide attempts.
13 years of follow-up, 125 (0.1 per cent) died by suicide and 816 (1 per cent) had attempted suicide (0.1 and 0.8 per 1000 years, respectively).
overall, 11 out of 4,095 participants with a self-reported history of sexual harassment in the workplace committed suicide, 114 out of 81,110 participants with no history of sexual harassment in the workplace, and 61 and 755 suicide attempts were committed among groups, respectively.
Cox regression analysis, sexual harassment in the workplace led to an increased risk of suicide (risk ratio 2.82) and suicide attempts (1.59), with no significant difference between male and female victims.
