Uveal melanoma (UM) is the most common intraocular malignancy in adults. Recent advances highlight the role of tumor-derived extracellular vesicles (TEV) and circulating hybrid cells (CHC) in UM tumorigenesis. Bridged with liquid biopsies, a novel technology that has shown incredible performance in detecting cancer cells or products derived from tumors in bodily fluids, it can significantly impact disease management and outcome.

Method: This study utilized the large-scale genome-wide association studies (GWAS) summary statistics to evaluate the causal association between gut microbiota and HE risk.
Purpose: To compare the efficacy and safety of pars plana vitrectomy (PPV) with silicone oil compared to gas tamponade for uncomplicated rhegmatogenous retinal detachment (RRD).
Design: Systematic review and meta-analysis.
Methods: A systematic literature search was conducted on Ovid MEDLINE, Embase, and the Cochrane Library from January 2000 to September 2023 for comparative studies evaluating the efficacy and safety of PPV with either silicone oil or gas tamponade in the setting of uncomplicated RRD.

Whole-genome duplication (WGD) is one of the most common genomic abnormalities in cancers. WGD can provide a source of redundant genes to buffer the deleterious effect of somatic alterations and facilitate clonal evolution in cancer cells. The extra DNA and centrosome burden after WGD is associated with an elevation of genome instability.

Background: Extracranial-intracranial bypass is an effective treatment option for moyamoya disease and in well-selected cases of anterior circulation intracranial atherosclerotic disease; however, the effectiveness of bypass is less evident in posterior circulation atherosclerosis. Updated surgical techniques and clinical guidelines necessitate modern appraisal of arterial bypass for symptomatic patients with posterior circulation atherosclerotic disease who are refractory to medical management.
Objective: To evaluate the complications, graft patency, and postoperative outcomes of arterial bypass for posterior circulation intracranial atherosclerotic disease.
Background: Managing intraoperative aneurysm rupture (IAR) during intracranial aneurysm clipping can be challenging given the excessive hemorrhage and limited field of view under the microscope for visualizing the proximal artery and safe temporary clipping.
Objective: To describe the first known use of robotic arm for safeguarding IAR in microsurgical aneurysm clipping.
Methods: A robotic arm was used to safeguard 3 microsurgical clipping cases (1 pericallosal and 2 middle cerebral artery) performed by a single surgeon.
Objective: Side-to-side (S-S) superficial temporal artery-middle cerebral artery (STA-MCA) bypass was reportedly used to treat a special moyamoya disease (MMD) patient with collaterals arising from the donor STA. However, the S-S technique is not routinely performed to date, and its benefits are still unknown for adult MMD. The purpose of this study was to investigate the possibility of routine use of the S-S technique for adult MMD.

Scleral fixation and iris fixation are common intraocular lens (IOL) implantation techniques performed because of zonulopathy. There is a lack of consensus regarding their comparative efficacy and safety. This study aims to compare the efficacy and safety outcomes after scleral-fixated (SF) vs iris-fixated (IF) IOL implantation or fixation in adults.
View Article and Find Full Text PDFBackground: Cerebral bypass is a valuable surgical technique in well-selected patient populations. Updated clinical guidelines and improved surgical techniques warrant a contemporary reevaluation of the complications and patency to inform clinical practice and enhance postoperative patient care.
Objective: To assess the complication rates and postoperative graft patency for the 3 most common indications for bypass surgery: moyamoya disease, intracranial atherosclerosis, and intracranial aneurysms.
Background: Carotid artery stenting is associated with a higher rate of stroke compared to carotid endarterectomy (CEA). This is likely due to procedural emboli resulting from plaque disruption. The transcarotid artery revascularization (TCAR) method aims to reduce the stroke rate by flow-reversal.

Background And Objective: No consensus exists on the comparative efficacy and safety of sutured scleral-fixated (SSF) and anterior chamber (AC) intraocular lens (IOL) implantation. We aim to compare outcomes of these two techniques.
Patients And Methods: A systematic literature search of MEDLINE, Embase, and Cochrane CENTRAL was conducted (2005 to 2020).
Background: Studies on gender differences in attention-deficit/hyperactivity disorder (ADHD) comorbidities in the Asian populations have been limited and previous studies have shown inconclusive findings. Singapore is a city-state country in Southeast Asia with a population of 5.7 million.

Few studies have operationalised how to quantify and improve the patient centeredness of communication during the dietitian outpatient consultation. We sought to evaluate the impact of a renal diet question prompt sheet (QPS) on patient centeredness (PC) in dietitian outpatient clinics and describe the impact of a renal diet QPS on the volume and pattern of communication between dietitians (n = 4) and patients/carers (n = 24, n = 11).
View Article and Find Full Text PDFObjective: Superficial temporal artery-middle cerebral artery (STA-MCA) bypass is a common approach for treating moyamoya disease (MMD); however, the selection of recipient vessels is still controversial, and its relationship with postoperative cerebral hyperperfusion (CHP) has not been revealed. The aim of the study was to investigate the relationship between the hemodynamic sources of the recipient parasylvian cortical arteries (PSCAs) and the occurrence of postoperative CHP.
Methods: The authors retrospectively analyzed the clinical data from 68 adult patients (75 hemispheres) with MMD who underwent STA-MCA bypass.
Background: Adherence to the diet prescription for chronic kidney disease is suboptimal. Interventions to improve dietary adherence suggest that improving communication between the patient and the health professional is fundamental to improving outcomes. Providing patients with a question prompt sheet prior to the consultation has been demonstrated to be an effective method for improving communication between patient and health professional.

Current therapies are limited to osmotic agents, such as hypertonic saline (HS), which reduce intracranial pressure. Although studies have demonstrated edema reductions following HS, tissue survival has not been thoroughly examined.

Background The standard incision for far-lateral suboccipital approaches has been the classic "reverse hockey stick." Although that incision provides ample exposure, concern has been raised that excessive muscle dissection and skin elevation might lead to accumulation of cerebrospinal fluid (CSF) under the flap with increased risk of CSF leak. We hypothesize that the C-shaped incision can minimize the amount of muscle dissection and provide optimal exposure and surgical outcomes.

Here, versatile, cost-effective, and large-area growth of uniform and pinhole-free g-CN films is achieved by using a thermal vapor condensation method under atmospheric pressure. A comparison of the X-ray diffraction and Fourier transform infrared data with the calculated infrared spectrum confirmed the graphitic build-up of films composed of tri-s-triazine units.

Advances such as high-definition (HD) and three-dimensional (3D) endoscopy have been introduced and clearly improve visualization. However, do both technologies maintain an increased field of view? We hypothesize that the field of view of 3D endoscopy is restricted relative to two-dimensional (2D) HD endoscopy.
