Ten-Year Results From the Natrelle 410 Anatomical Form-Stable Silicone Breast Implant Core Study

Background: Silicone breast implants have long been used for breast augmentation and reconstruction. During this time, these medical devices have gone through a number of modifications to improve their safety, quality, and clinical outcome performance. Objectives: The authors conducted a 10-year study to determine the safety and effectiveness of Natrelle 410 silicone breast implants. Methods: This prospective, multicenter study enrolled 941 subjects who were undergoing either augmentation, augmentation revision, reconstruction, or reconstruction revision. Data on complications, reoperations, explantations, and subject satisfaction were collected at annual clinic visits, and one-third of subjects underwent biennial magnetic resonance imaging (MRI) to screen for implant rupture. The authors used the Kaplan-Meier estimator to calculate risk rates for local complications, reoperations, and explantations. Results: Capsular contracture rates increased approximately 1% per year from the previously reported 6-year rates. The rates were significantly lower than those from the Natrelle round gel core study. The overall rate of confirmed ruptured implants in subjects who underwent MRI was 5.7%. Eleven late seromas were reported. The most common reason for explantation was a subject requesting a size or style change. Satisfaction rates remained high through 10 years, with most subjects saying they were somewhat or definitely satisfied with their implants. Conclusions: This 10-year prospective trial demonstrated the long-term safety and effectiveness of Natrelle 410 anatomical form-stable implants. The complication rates were low and the satisfaction rates were high

Terrestrial small mammal diversity and abundance in central Benin: Comparison between habitats, with conservation implications.

International audienceWe performed a terrestrial small mammal species inventory in the Agoua and Wari-Maro forest reserves (Benin). Four localities were sampled, and in each locality, three habitats were surveyed: dense forest, open forest or woodland savannah and shrub savannah. This is the first comprehensive inventory for small mammals in central Benin. We captured 794 small mammals representing twenty species (six shrew species, fourteen rodent species). Three new species that need to be described were recorded. We observed a mixture of both true forest species and of species adapted to a wider range of habitats ranging from savannah to forest clearings. Species with either Sudanian or Guinea–Congolian affinities were recorded, as well as a new species endemic to Togo and Benin. This rich biodiversity underlines the urgent need for an effective protection of these forests. The Sudanian species Crocidura cf. foxi was more abundant in Wari-Maro than in Agoua forest, while the Guineo–Congolian species Praomys misonnei and Hylomyscus sp were only captured in Agoua forest. These results are in agreement with the fact that these two forests belong to two distinct chorological zones

The Prevalence and Incidence of Epiretinal Membranes in Eyes With Inactive Extramacular CMV Retinitis

Purpose: To determine the prevalence and incidence of epiretinal membranes (ERM) in eyes with inactive extramacular cytomegalovirus (CMV) retinitis in patients with acquired immune deficiency syndrome (AIDS). Methods. A case–control report from a longitudinal multicenter observational study by the Studies of the Ocular Complications of AIDS (SOCA) Research Group. A total of 357 eyes of 270 patients with inactive CMV retinitis and 1084 eyes of 552 patients with no ocular opportunistic infection (OOI) were studied. Stereoscopic views of the posterior pole from fundus photographs were assessed at baseline and year 5 visits for the presence of macular ERM. Generalized estimating equations (GEE) logistic regression was used to compare the prevalence and 5-year incidence of ERM in eyes with and without CMV retinitis at enrollment. Crude and adjusted logistic regression was performed adjusting for possible confounders. Main outcome measures included the prevalence, incidence, estimated prevalence, and incidence odds ratios. Results: The prevalence of ERM at enrollment was 14.8% (53/357) in eyes with CMV retinitis versus 1.8% (19/1084) in eyes with no OOI. The incidence of ERM at 5 years was 18.6% (16/86) in eyes with CMV retinitis versus 2.4% (6/253) in eyes with no OOI. The crude odds ratio (OR) (95% confidence interval, CI) for prevalence was 9.8 (5.5–17.5) (P < 0.01). The crude OR (95% CI) for incidence was 9.4 (3.2–27.9) (P < 0.01). Conclusions: A history of extramacular CMV retinitis is associated with increased prevalence and incidence of ERM formation compared to what is seen in eyes without ocular opportunistic infections in AIDS patients

MELISSE, a large multicentric observational study to determine risk factors of venous thromboembolism in patients with multiple myeloma treated with immunomodulatory drugs

International audienceImmunomodulatory drugs (IMiDs) are associated with an increased risk of venous thromboembolism (VTE) in multiple myeloma (MM) patients. We designed MELISSE, a multicentre prospective observational study, to evaluate VTE incidence and identify risk factors in IMiDs-treated MM. Our objective was to determine the real-life practice of VTE prophylaxis strategy. A total of 524 MM patients were included, and we planned to collect information at baseline, at four and at 12 months, on MM therapy, on VTE risk factors and management. VTE incidence was 7% (n=31), including 2.5% pulmonary embolism (PE) (n=11), similar at four or 12 months. VTE was observed at all risk assessment levels, although the increased risk assessment level correlated to a lower rate of VTE, maybe due to the implemented thromboprophylaxis strategy. VTE occurred in 7% on aspirin vs 3% on low-molecular-weight heparin (LMWH) prophylaxis, and none on vitamin K antagonists (VKA). New risk factors for VTE in IMiDs-treated MM were identified. In conclusion, VTE prophylaxis is compulsory in IMiDs-treated MM, based on individualised VTE risk assessment. Anticoagulation prophylaxis with LMWH should clearly be prioritised in MM patients with high VTE risk, along with VKA. Further prospective studies will identify most relevant VTE risk factors in IMiDs-treated MM to select accurately which MM patients should receive LMWH prophylaxis and for which duration to optimise VTE risk reduction
