RESUMEN

Prevalence rates of peripartum depression and anxiety are high and correlate with adverse maternal and neonatal outcomes. Mindfulness-based interventions (MBI) have been shown to reduce mental distress during pregnancy. A multicenter, randomized controlled study was conducted after screening for depressive symptoms. The intervention group (IG) was given access to an 8-week supervised eMBI between weeks 29 and 36 of pregnancy and followed up to 5 months postpartum. Psychometric data were collected using the Edinburgh Postnatal Depression Scale (EPDS), the State-Trait Anxiety Inventory (STAI), the Pregnancy-Related Anxiety Questionnaire (PRAQ-R), the Freiburg Mindfulness Inventory (FMI-14) as well as the Patient Health Questionnaire (PHQ). Out of 5299 pregnant women, 1153 scored >9 on the EPDS and N = 460 were included in the RCT. No significant interaction effects for depressive symptoms and anxiety were found. Pregnancy- and birth-related anxiety decreased significantly in the IG and 6 weeks after birth, the rate of women at risk for adverse mental outcome was significantly lower compared to the CG. Mindfulness scores improved significantly in the IG. The eMBI program did not show effective regarding general depressive or anxiety symptoms, however, positive results were demonstrated regarding pregnancy and birth-related anxiety and the prevention of postpartum depression.

RESUMEN

BACKGROUND: Mental disorders are common during the peripartum period and may have far-reaching consequences for both mother and child. Unfortunately, most antenatal care systems do not provide any structured screening for maternal mental health. As a consequence, mental illnesses are often overlooked and not treated adequately. If correctly diagnosed, cognitive behavioral therapy is currently the treatment of choice for mental illnesses. In addition, mindfulness-based interventions (MBIs) seem to represent a promising treatment option for anxiety and depression during the peripartum period. Considering the internet's increasing omnipresence, MBIs can also be offered electronically via a (tablet) computer or smartphone (electronically based MBI = eMBI). OBJECTIVE: The current study aims to examine the clinical effectiveness and cost-effectiveness of an eMBI (the mindmom application) developed by an interdisciplinary team of gynecologists, psychologists, and midwives, teaching pregnant women how to deal with stress, pregnancy-related anxiety, and depressive symptoms. The study sample consists of pregnant women in their third trimester who screened positive for emotional distress. The mindmom study is a bicentric prospective randomized controlled trial (RCT), which is currently conducted at the University women's hospitals of Heidelberg and Tübingen, Germany. METHODS: Within the scope of the routine prenatal care, pregnant women attending routine pregnancy care in Baden-Wuerttemberg, Germany, are invited to participate in a screening for mental distress based on the Edinburgh Postnatal Depression Scale (EPDS). Women with an EPDS screening result > 9 will be referred to one of the mindmom coordinating study centers and are offered counseling either face-to-face or via videotelephony. After an initial psychological counseling, women are invited to participate in an eMBI in their last pregnancy trimester. The study will enroll N = 280 study participants (N = 140 per group), who are randomized 1:1 into the intervention (IG) or control group (treatment as usual = TAU). All participants are requested to complete a total of 7 digital assessments (5 visits pre- and 2 follow-up visits postpartum), involving self-report questionnaires, sociodemographic and medical data, physiological measures, and morning cortisol profiles. The primary outcome will be depressive and anxiety symptoms, measured by the Edinburgh Postnatal Depression Scale, the State Trait Anxiety Questionnaire, and the Pregnancy-Related Anxiety Questionnaire. Secondary outcomes include mindfulness, satisfaction with birth, quality of life, fetal attachment, bonding, mode of delivery, and cost-effectiveness. DISCUSSION: This is the first German RCT to examine the (cost-)effectiveness of an eMBI on maternal mental health during pregnancy. If successful, the mindmom app represents a low-threshold and cost-effective help for psychologically distressed women during pregnancy, thereby reducing the negative impact on perinatal health outcome.

RESUMEN

BACKGROUND: Peripartum depression and anxiety disorders are highly prevalent and are correlated with adverse maternal and neonatal outcomes. Antenatal care in Germany does not yet include structured screening and effective low-threshold treatment options for women facing peripartum depression and anxiety disorders. Mindfulness-based interventions (MBIs) are increasingly becoming a focus of interest for the management of such patients. Studies have shown a decrease in pregnancy-related stress and anxiety in expectant mothers following mindfulness programs. OBJECTIVE: The aim of this study was to explore the clinical effectiveness of a 1-week electronic course of mindfulness on prenatal depression and anxiety in hospitalized, high-risk pregnant women. We hypothesized that participating in a 1-week electronic MBI (eMBI) could alleviate symptoms of depression and anxiety during the hospital stay. METHODS: A prospective pilot study with an explorative study design was conducted from January to May 2019 in a sample of 68 women hospitalized due to high-risk pregnancies. After enrolling into the study, the participants were given access to an eMBI app on how to deal with stress, anxiety, and symptoms of depression. Psychometric parameters were assessed via electronic questionnaires comprising the Edinburgh Postnatal Depression Scale (EPDS), State-Trait Anxiety Inventory (STAI-S), and abridged version of the Pregnancy-Related Anxiety Questionnaire (PRAQ-R). RESULTS: We observed a high prevalence of peripartum depression and anxiety among hospitalized high-risk pregnant women: 39% (26/67) of the study participants in the first assessment and 41% (16/39) of the participants in the second assessment achieved EPDS scores above the cutoff value for minor/major depression. The number of participants with anxiety levels above the cutoff value (66% [45/68] of the participants in the first assessment and 67% [26/39] of the participants in the second assessment) was significantly more than that of the participants with anxiety levels below the cutoff value, as measured with the STAI-S. After completing the 1-week electronic course on mindfulness, the participants showed a significant reduction in the mean state anxiety levels (P<.03). Regarding pregnancy-related anxiety, participants who completed more than 50% of the 1-week course showed lower scores in PRAQ-R in the second assessment (P<.05). No significant changes in the EPDS scores were found after completing the intervention. CONCLUSIONS: Peripartum anxiety and depression represent a relevant health issue in hospitalized pregnant patients. Short-term eMBIs could have the potential to reduce anxiety levels and pregnancy-related anxiety. However, we observed that compliance to eMBI seems to be related to lower symptoms of pregnancy-related stress among high-risk patients. eMBIs represent accessible mental health resources at reduced costs and can be adapted for hospitalized patients during pregnancy.

RESUMEN

The lack of proper treatment for serious infectious diseases due to the emergence of multidrug resistance reinforces the need for the discovery of novel antibiotics. This is particularly true for tuberculosis (TB) for which 3.7% of new cases and 20% of previously treated cases are estimated to be caused by multi-drug resistant strains. In addition, in the case of TB, which claimed 1.5 million lives in 2014, the treatment of the least complicated, drug sensitive cases is lengthy and disagreeable. Therefore, new drugs with novel targets are urgently needed to control resistant Mycobacterium tuberculosis strains. In this manuscript we report the characterization of the thiopeptide micrococcin P1 as an anti-tubercular agent. Our biochemical experiments show that this antibiotic inhibits the elongation step of protein synthesis in mycobacteria. We have further identified micrococcin resistant mutations in the ribosomal protein L11 (RplK); the mutations were located in the proline loop at the N-terminus. Reintroduction of the mutations into a clean genetic background, confirmed that they conferred resistance, while introduction of the wild type RplK allele into resistant strains re-established sensitivity. We also identified a mutation in the 23S rRNA gene. These data, in good agreement with previous structural studies suggest that also in M. tuberculosis micrococcin P1 functions by binding to the cleft between the 23S rRNA and the L11 protein loop, thus interfering with the binding of elongation factors Tu and G (EF-Tu and EF-G) and inhibiting protein translocation.

RESUMEN

The discovery of Streptomyces-produced streptomycin founded the age of tuberculosis therapy. Despite the subsequent development of a curative regimen for this disease, tuberculosis remains a worldwide problem, and the emergence of multidrug-resistant Mycobacterium tuberculosis has prioritized the need for new drugs. Here we show that new optimized derivatives from Streptomyces-derived griselimycin are highly active against M. tuberculosis, both in vitro and in vivo, by inhibiting the DNA polymerase sliding clamp DnaN. We discovered that resistance to griselimycins, occurring at very low frequency, is associated with amplification of a chromosomal segment containing dnaN, as well as the ori site. Our results demonstrate that griselimycins have high translational potential for tuberculosis treatment, validate DnaN as an antimicrobial target, and capture the process of antibiotic pressure-induced gene amplification.
