Aims  Lipoprotein(a) [Lp(a)] is a causal and independent risk factor for cardiovascular disease (CVD). People with elevated Lp(a) are often prescribed statins as they also often show elevated low-density lipoprotein cholesterol (LDL-C) levels. While statins are well-established in lowering LDL-C, their effect on Lp(a) remains unclear. We evaluated the effect of statins compared to placebo on Lp(a) and the effects of different types and intensities of statin therapy on Lp(a). Methods and results  We conducted a systematic review and meta-analysis of randomized trials with a statin and placebo arm. Medline and EMBASE were searched until August 2019. Quality assessment of studies was done using Cochrane risk-of-bias tool (RoB 2). Mean difference of absolute and percentage changes of Lp(a) in the statin vs. the placebo arms were pooled using a random-effects meta-analysis. We compared effects of different types and intensities of statin therapy using subgroup- and network meta-analyses. Certainty of the evidence was determined using GRADE (Grading of Recommendations, Assessment, Development, and Evaluation). Overall, 39 studies (24 448 participants) were included. Mean differences (95% confidence interval) of absolute and percentage changes in the statin vs. the placebo arms were 1.1 mg/dL (0.5–1.6, P < 0.0001) and 0.1% (−3.6% to 4.0%, P = 0.95), respectively (moderate-certainty evidence). None of the types of statins changed Lp(a) significantly compared to placebo (very low- to high-certainty evidence), as well as intensities of statin therapy (low- to moderate-certainty evidence). Conclusion  Statin therapy does not lead to clinically important differences in Lp(a) compared to placebo in patients at risk for CVD. Our findings suggest that in these patients, statin therapy will not change Lp(a)-associated CVD risk.

Background: Gender-affirming treatments are reported to improve mental health significantly. However, a substantial number of transgender individuals report a relapse in, or persistence of, mental health problems following gender-affirming treatments. This is due to multiple stressors occurring during this period, and in general as a consequence of widespread stigma and minority stress. Aim: The aim of this pilot study was to identify different coping strategies that transgender individuals use in response to stressors prior to and following gender-affirming treatments, as mediator of mental health. Methods: Qualitative interviews were conducted to better understand the treatment outcomes and healthcare experiences of Dutch transgender individuals who had received gender-affirming treatments. Nineteen participants were included, of which 12 identified as (transgender) male, six as (transgender) female and one as transgender. Outcomes: Inductive coding and theory-informed thematic analysis were used to assess stressors (ncodes = 335) and coping strategies (ncodes = 869). Results: Four stressor domains were identified, including lack of support system, stressors related to transition, and physical and psychosocial stressors post-transition. We identified six adaptive coping strategies of which acceptance, help seeking and adaptive cognitions concerning gender and transition were reported most frequently. Of the seven maladaptive strategies that we identified, social isolation and maladaptive cognitions concerning gender and transition were the most-reported maladaptive coping strategies Clinical implications: The results indicated that transgender individuals may experience significant stress, both transgender-specific and non-specific, prior to and following gender-affirming treatments and, as a result, use many coping strategies to adapt. Increased awareness of stressors and (mal)adaptive coping strategies may help to improve mental healthcare and overall support for transgender individuals. Strengths and Limitations: This is the first (pilot) study to provide insight into the range of stressors that transgender individuals experience during and after gender-affirming treatments, as well as the variety of coping strategies that are used to adapt. However, since this was a pilot study assumptions and generalizations of the evidence should be made cautiously. Conclusion: Results of this pilot study showed that transgender individuals may undergo significant stress during and after gender-affirming medical treatment related to the treatments and the social experiences that occur during this period, and as a result, use a range of coping strategies to adapt to the stress.
