LNG-IUD safe and effective for managing heavy menstrual bleeding in adolescents with inherited bleeding disorders: Study

One in four adolescents with heavy menstrual bleeding (HMB)
since menarche may have an inherited bleeding disorder (IBD).
Levonorgestrel-containing intrauterine devices (LNG-IUDs) are the preferred
treatment for HMB in adolescents owing to the substantial and extended
reduction in bleeding and favorable side effect profile. Medical management
alone is frequently insufficient in persons with IBDs, yet several barriers
impact the use of LNG-IUDs in those with IBDs, including a lack of standardized
periprocedural guidelines, perceived higher bleeding risk associated with IUD
insertion complications, and placement-related pain. In addition, a recent
history of HMB increases the risk of IUD expulsion threefold. Moreover, first
spontaneous IUD expulsion is more frequent among adolescents, potentially because
of small uterine size. Expulsion risk factors include young age, history of
anemia, concurrent bleeding disorder diagnosis, and abnormal uterine bleeding.
While the LNG-IUD is as effective for HMB treatment in adolescents with IBDs as
those without IBDs, a key barrier to securing this extended efficacy is a more
frequent IUD expulsion rate within 30 days of insertion. Importantly,
expulsions after 30 days are not more frequent than in adolescents without
IBDs.

Cygan et al hypothesize dthat prophylactic menstrual
suppression after IUD insertion may reduce early (≤30 days) device expulsion.
The primary objective was to examine the rates of early IUD expulsion in
adolescents with IBDs with concurrent menstrual suppression.

The Penn State Health Women and Girls Bleeding Disorder
Clinic provides women’s health services for patients with suspected or
confirmed IBDs, including Ehlers-Danlos syndrome. This retrospective study included
adolescent girls (aged 10–21 years) with known or suspected IBDs undergoing IUD
insertion between November 1st, 2019 and September 7th, 2022. According to the
clinic practice pattern, participants continued their prior hormonal therapy
for at least 30 days after insertion. IUD insertion was within 60 days of the
last depot medroxyprogesterone acetate injection to ensure adequate coverage
for 30 days. Assessed data included the incidence of IUD expulsion, bleeding
disorder diagnosis, mode of menstrual suppression in the first 30 days after
insertion, subjective reported bleeding profiles at follow-up, and any observed
complications. Bleeding patterns were categorized as amenorrheic, light,
normal, or heavy.

Chart review identified 24 IUD insertions in 22 adolescents.
First follow-up for all 24 insertions occurred approximately 30 days after
insertion (mean 30 days).

For patients initially seen at 30 days, a second follow-up
visit was reviewed to confirm at least 30-day compliance with menstrual
suppression, evaluate bleeding pattern, and assess IUD status.

Hormonal menstrual suppression was utilized for 22 of 24
(92%) insertions.

Menstrual suppression was shown to be effective, with 14 of
24 patients (58%) reporting light bleeding and seven of 24 patients (29%)
reporting amenorrhea.

Altogether, no early expulsions because of excess bleeding
were noted after any of the 24 IUD insertions. There were no expulsions because
of heavy bleeding before 30 days for 21 of 22 individuals. One individual with
type IIA von Willebrand disease had two expulsions (the first within 30 days of
insertion and the second within 4 months [137 days]), neither associated with
excessive bleeding.

Given the absence of HMB, expulsions in this youngest
individual in the cohort were likely attributable to uterine size. A subsequent
19.5-mg LNGIUD inserted 1 year later remained in place for >12 months. One
individual experienced partial expulsion in the setting of excess bleeding more
than 6 months after placement, supporting the relationship between heavy blood
flow and displacement of the IUD from the endometrial cavity. One IUD was
electively removed within 4 months because of cramping without excessive
bleeding. No other expulsions were observed at the final follow-up. This
includes five individuals evaluated through 6 months and 11 individuals
followed through 12 months.

At final follow-up, for those whose IUDs remained in place,
bleeding was well controlled; 11 of 19 (58%) had amenorrhea and seven of 19
(36%) had light bleeding. In addition, there was no uterine perforation,
hemorrhage, or bleeding that required further hemostatic interventions.

No early (≤30 days after insertion) IUD expulsions because
of heavy bleeding were observed. If the risk for IUD expulsion in IBDs is
decreased during the first menses following insertion, the LNG-IUD’s favorable
bleeding profile may contribute to lower rates of late expulsion once patients
experience a reduction in monthly blood loss. While acknowledging that this
study is limited by loss of follow-up and subjective assessment of bleeding
profile improvement, the absence of early expulsion observed here in the
context of menstrual suppression is a promising improvement over similarly
sized studies that have reported higher rates of IUD expulsion in adolescents
with IBDs. The LNG-IUD is a safe and effective method of managing HMB in
adolescents with IBDs. Concurrent menstrual suppression for at least 30 days
after insertion, to prevent bleeding-related early expulsion in this
population, may maximize safety and minimize complications for this at-risk
group.

Women with Endometriosis and uterine fibroids likely to have Premature death, suggests study

A new study published in the British Medical Journal showed that women who have a history of uterine fibroids and endometriosis may be more likely to die young after they have finished having children. With clinically significant prevalences of 10% and 15% to 30%, respectively, endometriosis and uterine fibroids are prevalent conditions among women in their reproductive years.

Growth of endometrial-like tissue outside the uterus is a hallmark of endometriosis. Uterine fibroids, on the other hand, are smooth muscle cell-based, non-cancerous tumors that usually develop inside or near the myometrium. But uterine fibroids and endometriosis have similar genetic roots, and they grow through a combination of proinflammatory, immunological, and endocrine mechanisms. As a result, Yi-Xin Wang looked at how endometriosis and uterine fibroids affected the long-term risk of premature death in women from the Nurses’ Health Study II (NHSII), which has been conducted every two years for 30 years in the United States.

In 1989, 110,091 women between the ages of 25 and 42 who had never had a hysterectomy previously were diagnosed with cancer, cardiovascular disease, or endometriosis or fibroids were included. The key performance indicators Hazard ratios (calculated using Cox proportional hazards models) for overall and cause-specific premature death based on uterine fibroids confirmed by ultrasound or hysterectomy or endometriosis verified by laparoscopy and reported in biennial questionnaires.

Over the course of 2994,354 person years of follow-up, 4356 premature deaths were documented, including 90 from respiratory illnesses, 304 from cardiovascular disorders, and 1459 from cancer. Women with and without laparoscopically diagnosed endometriosis had crude incidences of all-cause premature death of 2.01 and 1.40 per 1000 person years, respectively.

Laparoscopically verified endometriosis was linked to a hazard ratio of 1.19 for premature mortality in age-adjusted models and these models were reinforced after controlling for behavioral variables and other possible confounders. In cause-specific mortality studies, uterine fibroids verified by ultrasound or hysterectomy were linked to a higher chance of dying from a malignant tumor of gynecological organs, but not to all cause premature death.

Women who reported both endometriosis and uterine fibroids had a higher risk of premature mortality from all causes. Overall, women who had a history of endometriosis and uterine fibroids were more likely to die young and die from gynecological malignancies.

Sarcopenic obesity may increase risk of knee osteoarthritis, finds research

A new study published in the PLOS ONE journal showed that in middle-aged and older Chinese people, obesity, sarcopenic obesity, and low muscular strength were linked to an increased risk of occurrence of symptomatic knee osteoarthritis (OA) seven years later.

The growing number of people at risk for osteoarthritis and other health issues is a result of the changing aging demographics and the rising incidence of obesity. About 80% of all cases of OA worldwide are caused by knee OA, which is a common ailment. Sarcopenia is a physiological phenomenon that naturally happens with aging and is characterized by a loss of muscle mass and strength that can be increased by co-morbid illness states.

Also, obesity raises the risk of sarcopenia due to ectopically accumulated lipids and chronic inflammation in skeletal muscle. This study examined whether reduced muscular strength may mediate the effects of obesity on the start of knee OA in middle-aged and older Chinese populations, as well as the possible impacts of muscle strength and sarcopenic obesity on the incidence of knee OA.

The China Health and Retirement Longitudinal Study yielded a total of 12,043 participants. Using Poisson regression models, the effects of sarcopenic obesity on the development of knee OA were computed. The mediating proportion of muscular strength on the relationship between obesity and incidence of knee OA was estimated using mediation analysis.

A total of 12,043 people were included in the trial, and 2,008 of them developed knee OA. Poisson analysis showed a causal relationship between the start of knee OA and both abdominal and overall obesity. The participants who had the greatest degree of normalized grip strength were 0.33 times less likely to experience incident knee OA than those in the control group, and chair-rising time was linked to a 0.65-fold higher risk of incident knee OA.

Similar findings were found via sensitivity analysis. When compared to the reference group, the participants with sarcopenic obesity had an approximately twofold increased incidence of acute knee OA. The relationship between obesity and the incidence of knee OA was mediated by normalized grip strength and chair-rising time. Overall, the study found that incidence-symptomatic knee OA is influenced by sarcopenic obesity and low muscular strength in middle-aged and older Chinese individuals.

Increased maternal butylparaben exposure elevates risk of asthma: Study

A recent study published in the Environmental Pollution journal highlighted how prenatal exposure to certain chemicals, commonly found in everyday products, may contribute to asthma development in children. This study analyzed the effects of maternal urinary phenol concentrations during early pregnancy on childhood asthma risk at age four.

The research examined a total of 3,513 mother-child pairs enrolled in the Japan Environment and Children’s Study (JECS) Sub-Cohort Study. Maternal urine samples, collected during the first trimester of pregnancy, were tested for 24 types of phenols, including parabens, bisphenol A, octylphenol, and nonylphenol. Also, phenol levels varied widely among participants. One key finding was that methylparaben was present at high concentrations in almost all samples, with an average level of 267.7 ng/ml and a large variation across individuals.

The analysis revealed significant associations between prenatal exposure to certain phenols and the risk of asthma in children. High levels of butylparaben in maternal urine were linked to a 54% increase in the odds of asthma onset by age four. Meanwhile, exposure to 4-nonylphenol showed a gender-specific effect where the boys born to mothers with detectable levels of this compound had more than double the odds of developing asthma (odds ratio: 2.09), and the girls showed no significant increase in risk.

These findings underline the complexity of phenol exposure and its potential to impact children’s health differently based on gender and chemical type. While the mechanisms remain unclear, the results indicate that certain phenols act as endocrine disruptors, possibly influencing respiratory health through hormonal pathways.

The study provides a crucial step toward understanding the risks of prenatal chemical exposure. Given that many of these phenols are widely used in consumer products, the findings emphasize the need for increased awareness and potential regulation to minimize exposure during pregnancy. And so, avoiding products containing butylparaben or nonylphenol during pregnancy might help reduce the risk of asthma in children.

Overall, these findings will inspire further studies to investigate the biological pathways involved and inform future public health guidelines to protect vulnerable populations, particularly pregnant women and children.

Risk of bleeding after dental extractions rather low among patients on antiplatelet therapy, suggests study

A study published in BMC Oral Health suggests that the risk of bleeding after dental extractions is rather low among patients on antiplatelet therapy.

This retrospective study aimed to identify high-risk dental extraction patients and the timing of postoperative haemorrhage to evaluate whether preventive hospitalization should be considered in patients on antiplatelet medication (AP) or anticoagulants. The study included 1595 procedures; 1319 were conducted under monotherapy (Group I: AP; Group II: indirect oral anticoagulant [IAC]; Group III: direct oral anticoagulant [DOAC]) and 276 under dual therapy (Group IV: double AP; Group V: AP and IAC; Group VI: AP and DOAC). We evaluated the incidence, frequency and timing of haemorrhage, hospitalization rate, and treatment of bleeding incidents. Results: The incidence of hemorrhagic events was significantly higher in the dual therapy groups compared to the monotherapy groups (p < 0.001). Comparing the procedures under monotherapy, those on DOAC (Group III) had a significantly higher risk of postoperative bleeding than Groups I and II (p < 0.001) and a higher rate of repeated bleeding episodes (p = 0.035).

Regarding bleeding incidents, 44% (dual therapy) vs. 51.1% (monotherapy) occurred on the day of surgery. The bleeding risk after dental extractions is overall low and patients were often hospitalized preventively due to their comorbidities rather than actual bleeding risk. Patients should be instructed about local compression, and surgeries should be completed in the morning to avoid emergency visits. However, patients with cardiovascular diseases and dual therapy had a higher risk of postoperative haemorrhage. Thus, hospitalization is to be considered in these cases.
