    Abstract This open access book examines the multiple intersections between national and international courts in the field of investment protection, and suggests possible modes for regulating future jurisdictional interactions between domestic courts and international tribunals. The current system of foreign investment protection consists of more than 3,000 international investment agreements (IIAs), most of which provide for investment arbitration as the forum for the resolution of disputes between foreign investors and host States. However, national courts also have jurisdiction over certain matters involving cross-border investments. International investment tribunals and national courts thus interact in a number of ways, which range from harmonious co-existence to reinforcing complementation, reciprocal supervision and, occasionally, competition and discord. The book maps this complex relationship between dispute settlement bodies in the current investment treaty context and assesses the potential role of domestic courts in future treaty frameworks that could emerge from the States' current efforts to reform the system. The book concludes that, in certain areas of interaction between domestic courts and international investment tribunals, the "division of labor" between the two bodies is not always optimal, producing inefficiencies that burden the system as a whole. In these areas, there is a need for improvement by introducing a more fruitful allocation of tasks between domestic and international courts and tribunals - whatever form(s) the international mechanism for the settlement of investment disputes may take. Given its scope, the book contributes not only to legal analysis, but also to the policy reflections that are needed for ongoing efforts to reform investor-State dispute settlement

    Title translation Preoperative conditioning and surgical strategies for treatment of complex abdominal wall hernias.
    Abstract The successful treatment of complex abdominal wall hernias requires individualized and if necessary interdisciplinary treatment concepts. Due to the high potential for abdominal and cardiopulmonary complications, specialized centers with a high level of expertise and experience should undertake the care of patients. Prehabilitation and optimization of hernia-specific risk factors and comorbidities play an essential role in the treatment algorithm. Preoperative conditioning prior to surgery can be crucial for success. Bariatric surgery for weight loss and administration of botulinum toxin A in the lateral abdominal wall for stretching the musculature to provide myofascial advancement and enlargement of the torso diameter are parts of such strategies. The preoperative progressive pneumoperitoneum has its justification in massive evisceration, facilitates repositioning of the viscera and helps the patient to slowly adapt to the postoperatively changed abdominal pressure conditions. From a surgical technical point of view, the following principle should apply: "mesh augmentation comes before defect bridging". This means preference should be given to a morphological functional restoration of the myofascicular abdominal wall compared to procedures that merely bridge abdominal wall defects based on meshing. The retromuscular preperitoneal mesh strengthening in the sense of a sublay technique is the gold standard. This can be extended to anterior or posterior component separation techniques in order to achieve a reduction of tension to the midline and/or to achieve enlargement of the space for mesh placement.

    Title translation Principles and parallels of prevention and repair of parastomal hernia with meshes.
    Abstract After formation of a permanent terminal stoma by enterostomy, parastomal hernia (PSH) occurs in up to 80% of cases and leads to a wide variety of symptoms and complications with a high rate of emergency operations due to incarceration (ca. 15%). Consequently, greater consideration should be given to PSH prevention even as early as the time of enterostomy and generously applied indications for elective repair of manifest PSH. The aim of this article is to summarize and evaluate the current evidence for PSH repair and prevention. Poor postoperative results after attempted repair of manifest PSH with slit meshes in different layers of the abdominal wall shift the focus onto stoma lateralization (sandwich and Sugarbaker techniques) or 3‑dimensional tunnel-shaped implants with meshes to cover the stomal edges. To date, the best strategy for PSH prevention has still not been defined and techniques with slit meshes show different results. Nevertheless, 10 prospective randomized trials, meta-analyses, a Cochrane review and guidelines from the European Hernia Society (EHS) about various slit-mesh devices in sublay, onlay and intraperitoneal positions confirmed significantly reduced rates of PSH after mesh augmentation compared to conventionally sutured enterostomy without morbidity associated with the implanted material. Despite the positive data situation PSH prevention is seldom performed in daily practice, which is due to uncertainty surrounding the most suitable surgical strategy, the necessity to spend additional time at the end of a demanding operation, the aversion to implanting meshes into a contaminated operative field and the lack of remuneration of preventive surgical procedures. Future trials should, therefore, no longer compare standard enterostomy techniques with one prevention method in general but should have a new focus on techniques providing adequate results in PSH repair (Sugarbaker, sandwich and 3‑D tunnel meshes), probe the advantages and evaluate the differences in outcome between these strategies.

    Title translation New laparoendoscopic and minimally invasive extraperitoneal mesh augmentation techniques for ventral hernia repair.
    Abstract In recent years techniques for ventral hernia repair have undergone a dynamic evolution with the development of minimally invasive and laparoendoscopic techniques. Despite the multitude of methods, five main criteria for setting the target have emerged: 1) functional and morphological reconstruction of the abdominal wall, 2) extraperitoneal mesh augmentation, 3) abandonment of penetrating fixation elements, 4) minimal surgical access trauma of the abdominal wall and 5) minimized intraperitoneal dissection that jeopardizes adherent intestinal structures. The mesh position varies between preperitoneal retromuscular and supraneurotic or preaponeurotic on the anterior rectus sheath. The different approaches can be carried out transhernially or distant from the abdominal wall defect. The latter can be realized by laparoscopic transperitoneal, endoscopic subcutaneous and endoscopic retromuscular/preperitoneal approaches. Some techniques can be extended to anterior or posterior component separation to reduce tension and to enlarge the space for mesh placement. Robot-assisted surgery opens up new perspectives in laparoendoscopic abdominal wall surgery due to additional instrumental degrees of movement. This enables the possibility of preperitoneal ventral hernia operations also behind and lateral to the posterior rectus muscle compartments as was only previously known below the arcuate line from inguinal hernia surgery.

    Abstract A new species of frog, Eleutherodactylus geitonos sp. nov., is described from the southeastern slope of the Cordillera Central, Dominican Republic. The new frog is closely related to E. haitianus and both species share a small size. They differ in some morphological proportions and other external features, coloration, advertisement calls and DNA sequences of the 16S rRNA gene. Morphological and bioacoustic comparisons with other species in the E. abbotti species group are also provided. Our preliminary genetic data suggest that the taxonomic status of E. neodreptus (a synonym of E. audanti) and E. melatrigonum need to be re-evaluated.

    Se describe una especie nueva de rana, Eleutherodactylus geitonos sp. nov., de la ladera sureste de la Cordillera Central, República Dominicana. Esta especie está cercanamente emparentada con E. haitianus, con la cual comparte una talla pequeña. Ambas especies se diferencian en algunas características y proporciones morfológicas, llamadas de anuncio, coloración y las secuencias del gen 16S ARNr. Son abordadas las comparaciones morfológicas y bioacústicas con otras especies del grupo E. abbotti. La filogenia obtenida a partir de datos genéticos preliminares sugieren que el estatus taxonómico de E. neodreptus (sinónimo de E. audanti) y E. melatrigonum requiere ser reevaluado.
