A new species of coral-dwelling crab (Decapoda: Brachyura: Cryptochiridae: Opecarcinus) from the West Pacific.

Based on material acquired from Green Island, Taiwan, using a combined approach of traditional morphology-based taxonomy and molecular barcoding, we describe a new species of coral-dwelling crab, Opecarcinus ngankeeae sp. nov., from the scleractinian hosts Pavona decussata and P.

Critical thermal maxima and oxygen uptake in Elysia viridis, a sea slug that steals chloroplasts to photosynthesize.

Photosynthetic animals produce oxygen, providing an ideal lens for studying how oxygen dynamics influence thermal sensitivity. The algivorous sea slug Elysia viridis can steal and retain chloroplasts from the marine alga Bryopsis sp. for months when starved, but chloroplast retention is mere weeks when they are fed another green alga, Chaetomorpha sp.

Phylomitogenomics elucidates the evolution of symbiosis in Thoracotremata (Decapoda: Cryptochiridae, Pinnotheridae, Varunidae).

Background: Thoracotremata belong to the large group of "true" crabs (infraorder Brachyura), and they exhibit a wide range of physiological and morphological adaptations to living in terrestrial, freshwater and marine habitats. Moreover, the clade comprises various symbiotic taxa (Aphanodactylidae, Cryptochiridae, Pinnotheridae, some Varunidae) that are specialised in living with invertebrate hosts, but the evolutionary history of these symbiotic crabs is still partially unresolved.

Methods: Here we assembled and characterised the complete mitochondrial genomes (hereafter mitogenomes) of three gall crab species (Cryptochiridae): , and .

Interspecific coral competition does not affect the symbiosis of gall crabs (Decapoda: Cryptochiridae) and their scleractinian hosts.

Coral reefs accommodate a myriad of species, many of which live in association with a host organism. Decapod crustaceans make up a large part of this associated fauna on coral reefs. Among these, cryptochirid crabs are obligately associated with scleractinian corals, in which they create dwellings where they permanently reside.

Telepresence for surgical assistance and training using eXtended reality during and after pandemic periods.

Existing challenges in surgical education (See one, do one, teach one) as well as the COVID-19 pandemic make it necessary to develop new ways for surgical training. Therefore, this work describes the implementation of a scalable remote solution called "TeleSTAR" using immersive, interactive and augmented reality elements which enhances surgical training in the operating room. The system uses a full digital surgical microscope in the context of Ear-Nose-Throat surgery.

Deep learning for surgical phase recognition using endoscopic videos.

Background: Operating room planning is a complex task as pre-operative estimations of procedure duration have a limited accuracy. This is due to large variations in the course of procedures. Therefore, information about the progress of procedures is essential to adapt the daily operating room schedule accordingly.

Efficacy of Internet-Based Cognitive Behavioral Therapy for Treatment-Induced Menopausal Symptoms in Breast Cancer Survivors: Results of a Randomized Controlled Trial.

Purpose: We evaluated the effect of Internet-based cognitive behavioral therapy (iCBT), with or without therapist support, on the perceived impact of hot flushes and night sweats (HF/NS) and overall levels of menopausal symptoms (primary outcomes), sleep quality, HF/NS frequency, sexual functioning, psychological distress, and health-related quality of life in breast cancer survivors with treatment-induced menopausal symptoms.

Patients And Methods: We randomly assigned 254 breast cancer survivors to a therapist-guided or a self-managed iCBT group or to a waiting list control group. The 6-week iCBT program included psycho-education, behavior monitoring, and cognitive restructuring.

Electronic Health Program to Empower Patients in Returning to Normal Activities After General Surgical and Gynecological Procedures: Intervention Mapping as a Useful Method for Further Development.

Background: Support for guiding and monitoring postoperative recovery and resumption of activities is usually not provided to patients after discharge from the hospital. Therefore, a perioperative electronic health (eHealth) intervention ("ikherstel" intervention or "I recover" intervention) was developed to empower gynecological patients during the perioperative period. This eHealth intervention requires a need for further development for patients who will undergo various types of general surgical and gynecological procedures.

A Randomized Study of Yoga for Fatigue and Quality of Life in Women with Breast Cancer Undergoing (Neo) Adjuvant Chemotherapy.

Objectives: To compare the effectiveness of yoga added to standard care (SC) versus SC only, in women with breast cancer during chemotherapy.

Design: A multicenter pragmatic, randomized controlled study.

Settings/location: Three hospitals in the Netherlands.

Breast magnetic resonance elastography: a review of clinical work and future perspectives.

This review on magnetic resonance elastography (MRE) of the breast provides an overview of available literature and describes current developments in the field of breast MRE, including new transducer technology for data acquisition and multi-frequency-derived power-law behaviour of tissue. Moreover, we discuss the future potential of breast MRE, which goes beyond its original application as an additional tool in differentiating benign from malignant breast lesions. These areas of ongoing and future research include MRE for pre-operative tumour delineation, staging, monitoring and predicting response to treatment, as well as prediction of the metastatic potential of primary tumours.

Intestinal Ralstonia pickettii augments glucose intolerance in obesity.

An altered intestinal microbiota composition has been implicated in the pathogenesis of metabolic disease including obesity and type 2 diabetes mellitus (T2DM). Low grade inflammation, potentially initiated by the intestinal microbiota, has been suggested to be a driving force in the development of insulin resistance in obesity. Here, we report that bacterial DNA is present in mesenteric adipose tissue of obese but otherwise healthy human subjects.

Molecular diversity of benthic ctenophores (Coeloplanidae).

Coeloplanidae, the largest family of benthic ctenophores, comprises 33 species, all described based on traditional morphological characteristics, such as coloration, length, and number of aboral papillae, which are highly variable and can be affected by fixation methods and environmental conditions. Thus, there is a need for reliable genetic markers to complement the morphological identifications at the species level. Here, we analyzed 95 specimens from 11 morphologically distinct species of benthic ctenophores from the Red Sea and Sulu Sea, and tested selected regions of four genetic markers (ITS1, 18S rRNA, 28S rRNA and COI) for their ability to differentiate between species.

Coat of many colours-DNA reveals polymorphism of mantle patterns and colouration in Caribbean Röding, 1798 (Gastropoda, Ovulidae).

The iconic gastropod genus is commonly observed in the Caribbean, where it lives in association with various octocorallian hosts. Each species in the genus has a unique, characteristic mantle pattern and colouration, which separates the valid taxa. Because of its abundance and recognisability has been used as a model organism in several studies concerning allelochemicals, reef degradation, and physical defence mechanisms.

Efficacy of Internet-Based Cognitive Behavioral Therapy in Improving Sexual Functioning of Breast Cancer Survivors: Results of a Randomized Controlled Trial.

Purpose We evaluated the effect of Internet-based cognitive behavioral therapy (CBT) on sexual functioning and relationship intimacy (primary outcomes) and body image, menopausal symptoms, marital functioning, psychological distress, and health-related quality of life (secondary outcomes) in breast cancer survivors (BCSs) with a DSM-IV diagnosis of a sexual dysfunction. Patients and Methods We randomly assigned 169 BCSs to either Internet-based CBT or a waiting-list control group. The CBT consisted of weekly therapist-guided sessions, with a maximum duration of 24 weeks.

Extreme mitochondrial variation in the Atlantic gall crab Opecarcinus hypostegus (Decapoda: Cryptochiridae) reveals adaptive genetic divergence over Agaricia coral hosts.

The effectiveness of migration in marine species exhibiting a pelagic larval stage is determined by various factors, such as ocean currents, pelagic larval stage duration and active habitat selection. Direct measurement of larval movements is difficult and, consequently, factors determining the gene flow patterns remain poorly understood for many species. Patterns of gene flow play a key role in maintaining genetic homogeneity in a species by dampening the effects of local adaptation.

Substitution of Usual Perioperative Care by eHealth to Enhance Postoperative Recovery in Patients Undergoing General Surgical or Gynecological Procedures: Study Protocol of a Randomized Controlled Trial.

Background: Due to the strong reduction in the length of hospital stays in the last decade, the period of in-hospital postoperative care is limited. After discharge from the hospital, guidance and monitoring on recovery and resumption of (work) activities are usually not provided. As a consequence, return to normal activities and work after surgery is hampered, leading to a lower quality of life and higher costs due to productivity loss and increased health care consumption.

Cognitive Impairment in a Subset of Breast Cancer Patients After Systemic Therapy-Results From a Longitudinal Study.

Context: Studies indicate adverse effects of breast cancer (BC) and cancer treatment on cognitive function.

Objectives: To investigate the effects of systemic treatment on cognitive performance in BC patients.

Methods: Participants were BC patients scheduled to receive systemic treatment (BC + SYST; n = 31), or no systemic treatment (BC; n = 24) and no-cancer (NC) controls (n = 33).

Phylogenetic relationships within the Phyllidiidae (Opisthobranchia, Nudibranchia).

The Phyllidiidae (Gastropoda, Heterobranchia, Nudibranchia) is a family of colourful nudibranchs found on Indo-Pacific coral reefs. Despite the abundant and widespread occurrence of many species, their phylogenetic relationships are not well known. The present study is the first contribution to fill the gap in our knowledge on their phylogeny by combining morphological and molecular data.

The phylogenetic position of a new species of Plakobranchus from West Papua, Indonesia (Mollusca, Opisthobranchia, Sacoglossa).

Plakobranchus papua Meyers-Muñoz & van der Velde, sp. n. from West Papua (Papua Barat province, Indonesia), is described based on its external morphology, colour pattern, internal anatomy, radula and reproductive system.

Trace fossil evidence of coral-inhabiting crabs (Cryptochiridae) and its implications for growth and paleobiogeography.

Members of the Cryptochiridae are small, fragile, symbiotic crabs that live in domiciles in modern corals. Despite their worldwide occurrence with over 50 species known today, their fossil record is unknown. We provide the first unambiguous evidence of cryptochirids in the fossil record through their crescentic pits, typical for certain cryptochirids, in Western Atlantic fossil corals, while the Eocene genus Montemagrechirus is excluded from the Cryptochiridae and referred to Montemagrechiridae fam.

Occurrence patterns of coral-dwelling gall crabs (Cryptochiridae) over depth intervals in the Caribbean.

Coral-associated invertebrates form a major part of the diversity on reefs, but their distribution and occurrence patterns are virtually unstudied. For associated taxa data are lacking on their distribution across shelves and environmental gradients, but also over various depths. Off Curaçao we studied the prevalence and density of coral-dwelling gall crabs (Cryptochiridae), obligate symbionts of stony corals.

Phylogenetic ecology of gall crabs (Cryptochiridae) as associates of mushroom corals (Fungiidae).

Coral-associated fauna is a relatively understudied topic. Hence, the nature of the relationship between an associated organism and its host is usually unknown. In the present study, the obligate associations between gall crabs (Decapoda: Cryptochiridae) and mushroom corals (Scleractinia: Fungiidae) are reviewed from a phylogenetic perspective.
