The effects of the etonogestrel 0.12mg/ethinyl estradiol 0.015mg vaginal ring (NuvaRing ®) on inflammatory biomarkers
Certain types of hormonal contraception have been associated with alterations of the inflammatory balance which is of concern due to known association of proinflammatory activation with risk of HIV. We investigated how the use of NuvaRing ® alters biomarkers of inflammation in the vaginal compartment. (Source: Fertility and Sterility)

Establishment of a Molding Procedure to Facilitate Formulation Development for Co-extrudates.
Abstract
Co-extrusion offers a number of advantages over conventional manufacturing techniques. However, the setup of a co-extrusion line is cost- and time-intense and formulation development is challenging. This work introduces a novel procedure to test the applicability of a co-extruded reservoir-type system at an early product development stage. We propose vacuum compression molding (VCM), a fast procedure that requires only small material amounts, for the manufacturing of cylindrical reservoir-type system. To this end, the commercially available co-extruded product NuvaRing(®) and variations thereof w...

Stroke and Etonogestrel/Ethinyl Estradiol Ring (NuvaRing): Clinical, Radiological, and Prognostic Features
A recent study found that NuvaRing (a vaginal contraceptive ring containing 15 µg ethinyl estradiol and 120 µg etonogestrel) has 2.5 times increased relative risk of thrombotic stroke compared to nonuse. (Source: Journal of Stroke and Cerebrovascular Diseases)

Comparison of combined hormonal vaginal ring and low dose combined oral hormonal pill for the treatment of idiopathic chronic pelvic pain: a randomised trial
Objective: To compare the efficacy and acceptability of combined hormonal vaginal ring with combined oral hormonal pill in women with idiopathic chronic pelvic pain. Study design: Randomised prospective interventional trial conducted in 60 women with idiopathic chronic pelvic pain. Women were randomised into two groups of 30 each. In each group, treatment was given for 84 days using either combined vaginal ring or combined oral hormonal pill. Hormonal vaginal ring releases 15mcg of ethinyl estradiol and 120mcg of the etonogestrel per day while the hormonal pill contained 30mcg of ethinyl estradiol and 150mcg of levonorg...

Comparison of combined hormonal vaginal ring and low dose combined oral hormonal pill for the treatment of idiopathic chronic pelvic pain: a randomised trial
Conclusion: Present study demonstrates for first time that both vaginal and oral hormonal therapy are effective in treatment of idiopathic chronic pelvic pain and vaginal ring may be a better choice with higher satisfaction rate and fewer side effects.

Hormonal contraceptives for contraception in overweight or obese women.
CONCLUSIONS: The evidence generally did not indicate an association between higher BMI or weight and effectiveness of hormonal contraceptives. However, we found few studies for most contraceptive methods. Studies using BMI, rather than weight alone, can provide information about whether body composition is related to contraceptive effectiveness. The contraceptive methods examined here are among the most effective when used according to the recommended regimen.We considered the overall quality of evidence to be low for the objectives of this review. More recent reports provided evidence of varying quality, while the quality...

Effect of Hormonal Contraception on the Function of Plasmacytoid Dendritic Cells and Distribution of Immune Cell Populations in the Female Reproductive Tract
Conclusions: The presented evidence suggests that the use of some types of hormonal contraception is associated with reduced functional capacity of circulating pDCs and altered immune environment in the female reproductive tract. (Source: JAIDS Journal of Acquired Immune Deficiency Syndromes)

The Case Files: Unusual Headache
By Al-Hashimi, Siddhartha DO; Leavens, John MD
A 23-year-old woman with a history of migraine headaches presented to the emergency department for a different-than-usual headache. She had a six-day history of intermittent headaches. The onset was at rest, and there was no history of trauma.
The headache was located behind her left eye, and it radiated into the posterior portion of her head. She characterized it as being 8/10 in intensity. Bright lights were reported as an exacerbating factor. The headache was associated with nausea and multiple episodes of emesis. She had 10 episodes of vomiting the evening prior to arri...

Stroke and Etonogestrel/Ethinyl Estradiol Ring (NuvaRing): Clinical, Radiological, and Prognostic Features. (P2.012)
Conclusions: In this largest case series of NuvaRing associated stroke to date, approximately half of the strokes are venous and half are arterial. Stroke typically occurred within the first year of use, and as soon as 2 weeks after NuvaRing initiation.Disclosure: Dr. Piran has nothing to disclose. Dr. Balucani has nothing to disclose.

Cerebral venous sinus thrombosis in the setting of combined vaginal contraception
We present a case of a 27-year-old women admitted to the hospital with migraine and left upper extremity weakness. Subsequent imaging with computed tomography and magnetic resonance angiography/venography demonstrated an acute-appearing central venous sinus thrombosis. Her only risk factor for venous thromboembolism (VTE) was the use of etonogestrel/ethinyl estradiol vaginal contraceptive ring (NuvaRing). The contraceptive ring was removed and the patient was treated according to the current guidelines. She achieved full neurologic recovery at 6 months’ follow-up. Here, we describe this unusual case and review the risk o...

Budget impact analysis of 8 hormonal contraceptive options.
Conclusions: Higher initial acquisition costs for the etonogestrel implant and levonorgestrel IUD were offset within 1 year by lower contraceptive failure rates and consequent pregnancy costs. Thus, after accounting for typical use failure rates of contraceptive products, the etonogestrel implant and levonorgestrel IUD emerged as the least expensive hormonal contraceptives.

Investigating the feasibility of temperature-controlled accelerated drug release testing for an intravaginal ring.
The objective of the present study was to investigate if temperature can be utilized to accelerate drug release from Nuvaring(®), a reservoir type intravaginal ring based on polyethylene vinyl acetate copolymer that releases a constant dose of contraceptive steroids over a duration of three weeks. The reciprocating holder apparatus (USP 7) was utilized to determine real-time and accelerated etonogestrel release from ring segments. It was demonstrated that drug release increased with increasing temperature which can be attributed to enhanced drug diffusion. An Arrhenius relationship of the zero-order release constants was ...
