RESUMO
The objective of this systematic review is to give a comprehensive interpretation of menstrual cycle changes after the COVID-19 vaccination. Additionally, it is imperative to assess reports of menstrual changes following vaccination to dispel concerns that COVID-19 vaccines hinder the likelihood of pregnancy in the long run. A literature review was conducted using digital databases to systematically identify the studies reporting any menstrual abnormalities after the COVID-19 vaccine. Detailed patient-level study characteristics including the type of study, sample size, administered vaccines, and menstrual abnormalities were abstracted. A total of 78â¯138 vaccinated females were included in this review from 14 studies. Of these, 39â¯759 (52.05%) had some form of a menstrual problem after vaccination. Due to the lack of published research articles, preprints were also included in this review. Menorrhagia, metrorrhagia, and polymenorrhea were the most commonly observed problems and the overall study-level rate of menstrual abnormality ranged from 0.83% to 90.9%. Age, history of pregnancy, systemic side-effects of COVID-19, smoking, and second dose of COVID-19 vaccine were predictors of menstrual problems after vaccination.
Alteraciones menstruales tras la vacunación contra la COVID-19: revisión sistemática Resumen El objetivo de esta revisión sistemática es aportar una interpretación amplia sobre los cambios de los ciclos menstruales tras la vacunación contra la COVID-19. Además, es imperativo evaluar los informes sobre los cambios menstruales tras la vacunación, para disipar preocupaciones en cuanto a que las vacunas contra la COVID-19 dificultan la probabilidad de embarazo a largo plazo. Se realizó una revisión de la literatura utilizando bases de datos digitales para identificar sistemáticamente los estudios que reportan cualquier alteración menstrual tras la vacuna contra la COVID-19. Se resumieron las características detalladas del estudio al nivel del paciente, incluyendo tipo de estudio, tamaño de la muestra, vacunas administradas, y alteraciones menstruales. Se incluyó en la revisión a un total de 78â¯138 mujeres vacunadas, procedentes de 14 estudios. De ellas, 39â¯759 (52,05%) tuvieron algún tipo de problema menstrual tras la vacunación. Debido a la falta de artículos de investigación publicados, también se incluyeron preimpresos en esta revisión. Menorragia, metrorragia, y polimenorrea fueron los problemas más comúnmente observados, oscilando la tasa global de alteraciones menstruales a nivel de estudios entre el 0,83 y el 90,9%. La edad, los antecedentes de embarazos, los efectos secundarios sistémicos de la COVID-19, el tabaquismo y la segunda dosis de la vacuna contra la COVID-19 fueron factores predictivos de problemas menstruales tras la vacunación.
RESUMO
Introduction Literature has shown varying results regarding the presence of group B Streptococcal (GBS) infection in pregnant females with preterm premature rupture of membranes (PPROM). The infection can be detrimental to maternal and neonatal well-being. There is a lack of studies that showed the extent of this problem in the local population of Pakistan. Our study aims to determine the frequency of GBS infection in females with PPROM. Methods This cross-sectional study was conducted at the Department of Obstetrics & Gynecology, Lahore General Hospital, Pakistan for six months. Informed consent was obtained from each patient. Demographic data were also recorded. Then the amniotic fluid sample was taken during a vaginal examination and was sent to the laboratory of the hospital for assessment of the presence or absence of GBS. Reports were assessed for GBS infection. Baseline demographics including age, body mass index (BMI), parity, and gestational age were presented as mean and standard deviation. Categorical data like parity and GBS infection were presented as frequency and percentage. Results The mean age of women was 30.04 ± 6.75 years. The mean gestational age of patients was 34.51 ± 1.75 weeks. Among 150 women, GBS infection was diagnosed in 24 (16%) patients. The occurrence of GBS infection was significantly associated with the age and parity status of women (p < 0.05). However, it was not significantly associated with gestational age and BMI of women (p > 0.05). Conclusion Our study showed a low prevalence of GBS infection in females presenting with PPROM. Nonetheless, the presence of infection can lead to detrimental outcomes including neonatal and maternal sepsis. The rate and risk factors of maternal and neonatal GBS colonization may vary in different communities. These rates, as well as the incidence of neonatal disease, need to be thoroughly evaluated to develop appropriate strategies for prevention.
