Perception of oral contraception - do women think differently from gynaecologists?

PURPOSE: This study aimed to assess the experience and satisfaction with contraceptives and use of Combined Oral Contraceptives (COC) by women and compare their perceptions with those of gynaecologists. METHODS: This was a multicentre survey study conducted in Portugal, during April and May, 2021 with women using contraceptives and gynaecologists. Online quantitative questionnaires were carried out. RESULTS: A total of 1508 women and 100 gynaecologists were included. Cycle control was the pill non-contraceptive benefit most valued by gynaecologists and women. For gynaecologists, the main pill concern was the risk of thromboembolic events, but they believed that weight gain was the main concern for their patients. The pill was the most used contraceptive (70%) and women were largely (92%) satisfied. The pill was associated with health risks for 85% of users, mainly thrombosis (83%), weight gain (47%), and cancer (37%). The attributes of the pill most valued by women are contraceptive efficacy (82%), followed by low risk of thromboembolic events (68%), good cycle control (60%), non-interference with libido and mood (59%) and weight (53%). CONCLUSION: Most women use contraceptive pills and are generally satisfied with their contraceptive. Cycle control was the most valued non-contraceptive benefit for gynaecologists and women, agreeing with physicians' beliefs about women. On the other hand, contrary to physicians' beliefs, that women's main concern is weight gain, women are mainly concerned with risks associated with contraceptives. Thromboembolic events are women's and gynaecologists most valued risk. Finally, this study indicates the need for physicians to better understand what COC users really fear.

Comparing women's perceptions with those of gynaecologists regarding Combined Oral Contraceptives, this study showed that contrary to physicians' beliefs, that women's main concern is weight gain, their main concern are risks associated with contraceptives. So, physicians need to better understand what women really fear.

Isolated Non-16/18 High-Risk Human Papillomavirus Cervical Infection: Re-Evaluation After One Year.

INTRODUCTION: High-risk human papillomavirus cervical infection is currently a well-established cause of cervical cancer. However, only a few women with persistent infections will develop cervical precancerous and malignant lesions. Approximately 20% of all cervical cancers are attributable to non-16/18 serotypes. This study aims to evaluate the results of our clinical approach to women with this infection. MATERIAL AND METHODS: We conducted an observational and prospective study from September 2012 to September 2017, which included women with isolated non-16/18 high-risk human papillomavirus infection (with normal cytology). After re-evaluation, two groups were compared: women with spontaneous regression of the infection and women with persistent infection. Clinical and demographic data were analysed as well as the rate of progression to precancerous and malignant lesions. RESULTS: We included 165 women, of which 121 were re-evaluated with co-test at least one year later. After re-evaluation, 13.2% of women revealed precancerous lesions but only two (1.7%) of them presented high-grade squamous intraepithelial lesions. Sixty-seven women (55.4%) showed spontaneous regression of the infection and 54 women (44.6%) maintained it. Women with persistent infection developed more precancerous lesions (27.8%; p < 0.001) and high-grade squamous intraepithelial lesions (3.7%; p < 0.001). There was also an association between persistent infection and postmenopausal status. DISCUSSION: Human papillomavirus 16/18 cervical infection is associated with higher risk of cervical cancer when compared with other serotypes. CONCLUSION: Re-evaluation with co-test one year after the diagnosis of isolated non-16/18 human papillomavirus infection seems to be a reasonable approach.

Introdução: O cancro cervical é causado pelo papiloma vírus humano de alto risco. No entanto, apenas algumas mulheres com infeções persistentes desenvolvem lesões pré-malignas e malignas. Aproximadamente 20% destas neoplasias são causadas por serotipos que não os 16 e 18. Este estudo surge com o objetivo de avaliar a nossa prática clínica neste âmbito. Material e Métodos: Realizámos um estudo observacional e prospetivo entre setembro de 2012 e setembro de 2017, com inclusão de mulheres com infeção cervical isolada com papiloma vírus humano de alto risco, excluindo os serotipos 16 e 18 (com citologia negativa). Após reavaliação, comparámos dois grupos: mulheres que apresentaram resolução espontânea da infeção e mulheres com infeção persistente. Foram analisados dados clínicos e demográficos bem como a taxa de progressão para lesões precursoras e malignas. Resultados: Incluímos 165 mulheres e reavaliámos com co-teste 121 delas com pelo menos um ano de intervalo. Após reavaliação, 13,2% desenvolveram lesões precursoras, mas apenas duas (1,7%) foram consideradas de alto grau. Sessenta e sete mulheres (55,4%) apresentaram resolução espontânea da infeção e 54 (44,6%) mantiveram-na. As mulheres com infeção persistente desenvolveram mais lesões precursoras (27,8%; p < 0,001) e de alto grau (3,7%; p < 0,001). Constatou-se uma associação entre a persistência da infeção e pós-menopausa. Discussão: A infecção cervical com serotipos 16/18 associa-se a uma maior risco de desenvolvimento de cancro cervical quando comparada com outros serotipos. Conclusão: A reavaliação com co-teste um ano após o diagnóstico de infecção cervical isolada com papiloma vírus humano de alto risco, excluindo os serotipos 16 e 18, parece ser uma abordagem adequada.

Serum vitamin D levels correlate with the presence and histological grading of colorectal adenomas in peri and postmenopausal women.

BACKGROUND & AIMS: Vitamin D is known to modulate immune function and proliferation. Higher vitamin D [25(OH)D3] serum levels have been reported to have protective effects on adenoma detection and colorectal cancer (CRC) development and survival. METHODS: This retrospective cohort study included 315 peri and post-menopausal women submitted to opportunistic colorectal and osteoporosis screening at the gynaecology outpatient clinic of a tertiary medical centre between 2004 and 2015. Colonoscopy findings were correlated with 25(OH)D3 and PTH serum levels, and subsequently adjusted in a multivariate logistic regression model. Confounding factors included demographic and colorectal risk factors, pharmacological therapies and bone densitometry metrics. RESULTS: A total of 77 lesions were identified in 66 patients. Vitamin D insufficiency (<30 ng/mL) and deficiency (<20 ng/mL) were identified in 79.4% and 35.2% of patients, respectively. In univariate analysis, lower levels of 25(OH)D3 were associated with polyp, adenoma and advanced adenoma detection. After adjusting for confounders, an association with polyps could not be observed, but a trend towards a negative correlation with adenoma detection was found (adjusted OR: 0.96; 95% CI 0.92-1.00; p = 0.083). Regarding advanced adenoma detection, 25(OH)D3 (adjusted OR: 0.86; 95% CI 0.77-0.97; p = 0.013) proved to be an independent predictive factor. No association was found between 25(OH)D3 levels and lesion detection site. CONCLUSION: The association of 25(OH)D3 serum levels with colorectal lesions seems to be restricted to adenomatous lesions and is influenced by histological grading. Vitamin D may be a valuable biomarker for optimization of risk stratification in group-specific CRC screening protocols.

Activity of two enzymes associated with apoptosis and cell aging in arterial hypertension.

OBJECTIVE: To study the activity of two enzymes, transmembrane reductase (TMR) and cytosolic low molecular weight protein tyrosine phosphatase (ACP1), in arterial hypertension (HT) in a sample of adults aged over 50 years. METHODS: A sample of 153 adults, 77 with hypertension and 76 normotensive (NT), aged between 50 and 90 years (mean: 71.87 +/- 11.59), of both sexes, was studied. TMR (mmol/cell/h) and ACP1 (micromol/gHb/h) activity in red blood cells was determined by spectrophotometry. Statistical analysis was carried out using the Student's t test and Pearson's correlation. RESULTS: We observed a significant difference in TMR activity between normotensive and hypertensive subjects, with lower levels in the hypertensives (NT = 4.762 +/- 2.595; HT = 3.878 +/- 1.748), p = 0.01. ACP1 activity, although higher in hypertensive patients, did not differ significantly from normotensive subjects (p = 0.08) (NT = 242.827 +/- 97.618; HT = 309.561 +/- 150.738). No correlation was observed between the activity of the two enzymes in either the hypertensive or the normotensive group. CONCLUSIONS: The lower level of activity of transmembrane reductase in arterial hypertension may be implicated in cardiovascular aging processes, reinforced by greater cytosolic acid phosphatase activity, with repercussions on cell proliferation and energy metabolism, leading to atherosclerosis.

Oxidative stress in Portuguese children with Down syndrome.

BACKGROUND: Individuals with Down syndrome have an accelerated process of ageing which is thought to be associated with oxidative stress. AIM: Since Zn/Cu superoxide dismutase is increased by about 50% in children with Down syndrome, glutathione and other less known antioxidant mechanisms were studied to determine whether there were changes in reactive oxygen species. METHODS: Plasma reduced and oxidised glutathione and red blood cells enzymes including acid phosphatase, methemoglobin reductase and transmembrane reductase were evaluated in Portuguese children with Down syndrome and their siblings, who were used as a control group. RESULTS: No significant differences were found between the study and control groups. A negative correlation was noted between total glutathione and acid phosphatase in the siblings without Down syndrome, but not in the children with Down syndrome. CONCLUSION: Although it is claimed that the production of hydrogen peroxide is enhanced in children with Down syndrome, their antioxidant mechanisms do not seem to be significantly different compared with their siblings. This may result in an excess of reactive oxygen species that could help to explain accelerated ageing in children with Down syndrome. Further studies will be needed to shed light on these mechanisms.
