Vacuna del virus del papiloma humano: valoración bioética de la discriminación por sexo

La infección por el virus del papiloma humano (VPH) constituye la causa necesaria, aunque no suficiente, de la enfermedad de transmisión sexual más frecuente en el mundo, responsable del 4,5 % de todos los cánceres en ambos sexos. La vacunación frente al VPH, con niveles de eficacia y seguridad similares en ambos sexos, está dirigida básicamente a mujeres, para reducir la incidencia de infección y sus consecuencias, como el cáncer de cérvix. La transmisibilidad del virus en ambos sexos y la inmunidad colectiva que proporciona la vacunación universal hace que su extensión al sexo masculino constituya una cuestión no solo de salud pública, sino también un dilema bioético relacionado con la protección de la salud y la equitativa distribución de los recursos. Este trabajo aborda el análisis bioético de la extensión de la vacunación contra VPH a ambos sexos.

Human Papillomavirus (HPV) infection is the most common sexually transmitted disease worldwide, responsible for 4.5 % of all cancers in both sexes. HPV vaccination, with similar levels of efficacy and safety in both sexes, is aimed at women to prevent cervical cancer. The transmissibility of the virus in both sexes and the herd immunity provided by universal vaccination makes its extension to the male sex a matter not only of public health but also a bioethical dilemma related to the protection of health and the equitable distribution of resources. This research addresses the bioethical analysis of the extension of HPV vaccination to both sexes.

A infecção pelo vírus do papiloma humano (HPV, na sigla em inglês) constitui a causa principal, ainda que não suficiente, da doença de transmissão sexual mais frequente no mundo, responsável por 4,5 % de todos os cânceres em ambos os sexos. A vacinação contra o HPV, com níveis de eficácia e segurança semelhantes em ambos os sexos, está orientada basicamente a mulheres, para reduzir a incidência de infecção e suas consequências, como o câncer do colo do útero. A transmissão do vírus em ambos os sexos e a imunidade coletiva que a vacinação universal promove fazem com que sua extensão ao sexo masculino constitua uma questão não apenas de saúde pública, mas também um dilema bioético relacionado com a proteção da saúde e a equitativa distribuição dos recursos. Nesse sentido, neste trabalho, é abordada a análise bioética da extensão da vacinação contra o HPV em ambos os sexos.

Effect of aerobic water exercise during pregnancy on epidural use and pain: A multi-centre, randomised, controlled trial.

OBJECTIVE: The physical and psychological benefits of exercise during pregnancy are well established. However, the impact of exercise on pain during labour and the use of epidural analgesia has been less explored. The main aim of this study was to analyse the effectiveness and safety of moderate aerobic water exercise by pregnant women on the subsequent use of epidural analgesia during labour, induction of labour, mode of delivery, and pain perception. DESIGN: A multi-centre, parallel, randomised, evaluator blinded, controlled trial in a primary care setting. SETTING: Primary care centres in a health district of a tertiary obstetric metropolitan hospital in Mallorca, Spain. PARTICIPANTS: Pregnant women (14 to 20 weeks' gestation) who had low risk of complications. METHODS: Three hundred and twenty pregnant women were randomly assigned to two groups: women who practiced moderate aquatic aerobic exercise with usual antenatal care, and those who received usual prenatal care alone. The gynaecologist, anaesthesiologist and midwife who assisted the women during labour were blinded to group allocations. Principal outcome: use of epidural analgesia during labour. Other outcomes: use of epidural analgesia before 6 cm cervical dilation, labour pain, type of delivery, time of active labour, episiotomy or perineal tear, and induction of labour. RESULTS: The exercise program did not affect the use of epidural analgesia (OR = 0.79, 95% CI = 0.44 to 1.40), vaginal delivery (OR = 1.35, 95% CI = 0.73 to 2.41), or caesarean section (OR = 0.94, 95% CI = 0.47 to 1.89). However, women in the exercise group reported less pain during labour (mean difference: -0.6, 95% CI = -1.11 to -0.09). The two groups (moderate aquatic aerobic exercise versus usual antenatal care) showed no significant differences in maternal or newborn adverse events. CONCLUSION: Aquatic aerobic exercise during pregnancy had no effect on the use of epidural analgesia during labour, whereas pain perception was lower after aquatic exercise compared to usual care in pregnancy. The intervention was safe for pregnant women and their newborns.

Effectiveness of Moderate-Intensity Aerobic Water Exercise during Pregnancy on Quality of Life and Postpartum Depression: A Multi-Center, Randomized Controlled Trial.

BACKGROUND: The global prevalence of postpartum depression is about 20%. This disease has serious consequences for women, their infants, and their families. The aim of this randomized clinical trial was to analyze the effectiveness and safety of a moderate-intensity aerobic water exercise program on postpartum depression, sleep problems, and quality of life in women at one month after delivery. METHODS: This was a multi-center, parallel, randomized, evaluator blinded, controlled trial in a primary care setting. Pregnant women (14-20 weeks gestational age) who had low risk of complications and were from five primary care centers in the area covered by the obstetrics unit of Son Llatzer Hospital (Mallorca, Spain) were invited to participate. A total of 320 pregnant women were randomly assigned to two groups, an intervention group (moderate aquatic aerobic exercise) and a control group (usual prenatal care). One month after birth, sleep quality (MOS sleep), quality of life (EQ-5D), and presence of anxiety or depression (EPDS) were recorded. FINDINGS: Women in the intervention group were less likely to report anxiety or depression on the EQ5D (11.5% vs. 22.7%; p < 0.05) and had a lower mean EPDS score (6.1 ± 1.9 vs. 6.8 ± 2.4, p < 0.010). The two groups had no significant differences in other outcomes, maternal adverse events, and indicators of the newborn status. CONCLUSION: Moderate-intensity aquatic exercise during pregnancy decreased postpartum anxiety and depressive symptoms in mothers and was safe for mothers and their newborns.

Effectiveness and safety of moderate-intensity aerobic water exercise during pregnancy for reducing use of epidural analgesia during labor: protocol for a randomized clinical trial.

BACKGROUND: Epidural analgesia during labor can provide effective pain relief, but can also lead to adverse effects. The practice of moderate exercise during pregnancy is associated with an increased level of endorphins in the blood, and this could also provide pain relief during labor. Aerobic water exercises, rather than other forms of exercise, do not negatively impact articulations, reduce edema, blood pressure, and back pain, and increase diuresis. We propose a randomized controlled trial (RCT) to evaluate the effectiveness and safety of a moderate water exercise program during pregnancy on the need for epidural analgesia during labor. METHODS: A multi-center, parallel, randomized, evaluator blinded, controlled trial in a primary care setting. We will randomised 320 pregnant women (14 to 20 weeks gestation) who have low risk of complications to a moderate water exercise program or usual care. DISCUSSION: The findings of this research will contribute toward understanding of the effects of a physical exercise program on pain and the need for analgesia during labor.
