Propofol, a commonly used intravenous anaesthetic, binds to type A gamma aminobutyric acid (GABA) receptors in mammalian brain. Previous work on its anaesthetic action has characterised either the biochemistry underlying propofol binding or the associated changes in brain network dynamics during sedation. Despite these advances, no study has focused on understanding how propofol action at the cellular level results in changes in brain network connectivity.

We used human whole-brain microarray data to generate distribution maps for genes that mark the primary GABAergic cortical interneurone subtypes (somatostatin, parvalbumin [PV], and 5-hydroxytryptamine 3A. Next, 25 healthy participants underwent propofol-induced sedation during resting state functional MRI scanning. We used partial least squares analysis to identify the brain regions in which connectivity patterns were most impacted by propofol sedation. We then correlated these multimodal cortical patterns to determine if a specific interneurone subtype was disproportionately expressed in brain regions in which connectivity patterns were altered during sedation.

Brain networks that were significantly altered by propofol sedation had a high density of PV-expressing GABAergic interneurones. Brain networks that anticorrelated during normal wakefulness, namely the default mode network and attentional and frontoparietal control networks, increased in correlation during sedation.

PV-expressing interneurones are highly expressed in brain regions with altered connectivity profiles during propofol-induced sedation. This study also demonstrates the utility of leveraging multiple datasets to address multiscale neurobiological problems.

In recent years, the vitrification and laser warming of coral propagules has demonstrated promising results. During cryopreservation, cellular membranes undergo substantial reconfigurations that may affect survival. Fat enrichment may alter the physical proprieties of cell membranes and improve resistance to low temperatures. Therefore, the aim of this study was to determine whether supplementation of exogenous lipids using liposomes would improve cryosurvival and further development of the vitrified and laser-warmed coral larvae of Seriatopora caliendrum and Pocillopora verrucosa. A vitrification solution (VS) composed of 2 M ethylene glycol (EG), 1 M propylene glycol (PG), 40% (w/v) Ficoll, and 10% gold nanoparticles (at a final concentration of 1.2 × 1018 particles/m3 and an optimised emission wavelength of 535 nm) was chosen. Coral larvae were subjected to vitrification with VS incorporating one of four lipid classes phosphatidylcholine (PC), phosphatidylethanolamine (PE), erucic acid (EA), and linoleic acid (LA). Warming was achieved using a single laser pulse (300 V, 10 ms pulse width, 2 mm laser beam diameter). A significantly higher vitality rate was observed in S. caliendrum larvae subjected to vitrification and laser warming with EA-incorporated VS, and P. verrucosa larvae vitrified and laser warmed using PE-incorporated VS achieved a significantly higher settlement rate. Our study demonstrated that supplementation of exogenous lipids with liposomes enhances coral larvae cryotolerance and improves cryopreservation outcomes. Lipid enrichment may play a key role in cryobanking coral propagules, and in propagule development after thawing.Grading is one of the best prognostic indicators of prostate cancer with Gleason grade 5 having the worst outcome. The prognostic influence of grade 5 patterns remains uncertain. A total of 646 prostate needle biopsy sets with Gleason score (GS) 9-10 prostatic adenocarcinoma were prospectively analysed. Patterns of grade 5 were correlated with radical prostatectomy (RP) adverse findings of high tumour volume (TV), extra-prostatic extension (EPE), seminal vesicle invasion (SVI) and lymph node involvement (LNI) in 472 and biochemical recurrence (BCR) in 338 patients after RP. Mean age and serum PSA were 69 years (range 37-91) and 26.1 ng/mL (range 1.4-1800), respectively. Gleason scores were 4+5=9 in 539 (83%), 5+4=9 in 94 (15%) and 5+5=10 in 13 cases (2%). Clusters/cords, single cells, sheets and comedocarcinoma were found in 86%, 69%, 26% and 18% with a pure pattern in 25% of cases. Comparing cases with and without sheets, there were no significant differences with RP high TV (p=0.8577), EPE (p=0.5372), SVI (p=0.5183) and LNI (p=0.4323). However, the presence of sheets predicted a significantly higher BCR rate (p=0.0033), while for tumours with single cells, the interval to BCR was significantly shorter (p less then 0.0001). GSK461364 Comparing cases with and without the other patterns, two other significant differences were found. Comedocarcinoma predicted high TV (p=0.0230) and single cells predicted EPE (p=0.0101). This study shows that all patterns currently used to assign a Gleason grade 5, including sheets, comedocarcinoma, single cells and clusters/cords, are associated with aggressive outcomes validating their inclusion in grade 5.Antisynthetase syndrome (AS) is a rare disease that affects patients with inflammatory myopathies such as polymyositis (PM) and dermatomyositis (DM). In patients with AS, up to 95% of patients develop antisynthetase syndrome-associated interstitial lung disease (AS-ILD). Although AS-ILD commonly occurs in patients with a well-established diagnosis of AS, it can be the first or only manifestation of an occult AS. The frequency of interstitial lung disease (ILD), myopathy, and skin involvement are often dependent on the type of myositis-specific antibodies present. AS-ILD patients who are positive for both anti-Jo-1 and anti-SSA/RO-52 autoantibodies often present with a severe degree of lung restriction on pulmonary function tests and radiologic imaging with an inadequate response toward immunosuppressive therapies. We describe a 65-year-old woman who presents with chronic dyspnea. She was initially diagnosed with corticosteroid-resistant cryptogenic organizing pneumonia based on the radiological findings on her CT chest. link2 Her symptoms did not improve, and she suffered from intolerable corticosteroid-related side effects. link3 Reviews of systems were positive for arthritis and Raynaud's phenomenon. She was found to have elevated inflammatory markers and autoantibodies such as anti-Jo-1, anti-RO-52, and anti-SSA. A diagnosis of AS-ILD resistant to corticosteroid therapy was made. Her lung function improved with combination therapy of mycophenolate and rituximab. Our case highlights that a detailed history and physical exam, compatible radiologic imaging, and autoantibodies are essential for the diagnosis of AS-ILD.

The aim of this study is to evaluate the safety and effectiveness results of sleeve gastrectomy as a bariatric technique.

Observational follow-up study of a cohort of patients who underwent sleeve gastrectomy in our center between 2008 and 2017. A total of 223 patients were included 166 as a primary technique (group 1) and 57 as a hypothetical first stage (group 2).

In group 1, the postoperative morbidity is 12.6%, with a fistula rate of 4.2%; 5.4% required reoperation and mortality was 0.6%. In group 2, postoperative morbidity is 14%, with a fistula rate of 5.3%; 10.5% required reoperation and mortality was 5.3%. In group 1, 79.6% and 62.5% of patients at 2 and 5 years respectively managed to achieve a % EBMIL>50%. In group 2, the second stage was completed only in 8 patients (14.0%). Of the patients who did not complete the second stage, 32.2% and 5.9% achieved a % EEBMIL>100% at 2 and 5 years. Analyzing those who completed the second stage, the mean EEBMIL% was 90.5% and 93.4% at 2 and 5 years.

Sleeve gastrectomy is a safe technique in patients with BMI<45 and effective in terms of weight loss in the short-medium term. In patients with BMI>55, a preoperative optimization aimed at reducing morbidity and mortality is necessary, as well as adequately planning the second stage, without which it is clearly insufficient.

Use of laparoscopic pancreaticoduodenectomy (LPD) in place of open pancreaticoduodenectomy (OPD) remains controversial. Our aim was to evaluate the results of LPD versus OPD in non-pancreatic periampullary adenocarcinoma (NPPC), a less aggressive tumor.

Here, 488 NPPC patients who underwent LPD or OPD were analyzed in this study. The propensity score matching was used to balance the patients in two groups. Statistical analysis was conducted to investigate the differences between LPD and OPD in patients with NPPC.

The LPD group had shorter operative time, less intraoperative bleeding, and less postoperative hospital stay than OPD group. The 30- and 90-day mortality rates were significantly lower in LPD than in OPD group. There was no statistical difference in long-term survival between the two groups.

For NPPC, LPD may be the preferred surgical treatment due to its advantages over OPD in terms of intraoperative blood loss and short-term mortality.

The incidence of placenta accreta spectrum has increased in recent years, largely driven by increasing rates of cesarean delivery. Prenatal detection of placenta accreta spectrum is primarily made by ultrasound and is important to reduce maternal morbidity associated with the condition. Despite a large body of research on various placenta accreta spectrum ultrasound markers and their screening performance, inconsistencies in the literature persist. In response to the need for standardizing the definitions of placenta accreta spectrum markers and the approach to the ultrasound examination, the Society for Maternal-Fetal Medicine convened a task force with representatives from the American Institute of Ultrasound in Medicine, the American College of Obstetricians and Gynecologists, the American College of Radiology, the International Society of Ultrasound in Obstetrics and Gynecology, the Society for Radiologists in Ultrasound, the American Registry for Diagnostic Medical Sonography, and the Gottesfeld-Hohler Memorial Ultrasound Foundation. The goals of the task force were to assess placenta accreta spectrum sonographic markers on the basis of available data and expert consensus, provide a standardized approach to the prenatal ultrasound evaluation of the uterus and placenta in pregnancies at risk of placenta accreta spectrum, and identify research gaps in the field. This manuscript provides information on the Placenta Accreta Spectrum Task Force process and findings.
