Article Synopsis
  • Sleep architecture in people with depression, especially older adults, is not well-defined, prompting a study to compare sleep patterns between depressed and non-depressed individuals aged over 50.
  • A systematic review identified 15 articles from over 2000, with data showing that depressed adults had significantly poorer sleep quality — less total sleep time, longer time to fall asleep, and more disruptions during the night compared to controls.
  • Although older depressed adults had some distinct sleep characteristics, inconsistencies in findings and the removal of certain studies affected the overall results, indicating that differences in sleep architecture vary among different age groups and are not consistently observed.

Article Synopsis
  • * In lab tests, starving copepods actively ingested pieces of the microplastic, which caused the fibers to penetrate deep into their digestive systems.
  • * All copepods with the fibers in their mouths died within 24 hours, indicating that even a single piece of microplastic can have a lethal impact on marine life due to its non-degradable nature.

Eating disorders (EDs) present a chronic issue to child paediatric mental health services due to their high mortality and relapse rates. The transition from Child and Adolescent Mental Health Services to Adult Mental Health Services is a particularly high-risk period for young people with EDs given their high vulnerability to change, which can negatively impact treatment outcomes. However, there is lack of evidence on the feasibility of inclusive and youth-specific interventions that address the multiple and complex needs of this group during their transition to adult care.

This study investigated the impacts of the removal of sand bund on the macrobenthos community structure, seagrass cover, and sediment particle size in Merambong Shoal, Malaysia. The reclamation project deposited sand bund in the middle of Merambong seagrass shoal, resulting in its division into northern (NS) and southern (SS) halves. Ecosystem changes were monitored over a 31-month period using the transect lines method.

Endoscopic ultrasound guided-pancreatic duct drainage (EUS- PDD) is one of the most technically challenging procedures for the interventional endoscopist. The most common indications for EUS- PDD are patients with main pancreatic duct obstruction who have failed conventional endoscopic retrograde pancreatography (ERP) drainage or those with surgically altered anatomy. EUS- PDD can be performed via two approaches: the EUS-rendezvous (EUS- RV) or the EUS-transmural drainage (TMD) techniques.

Management of upper gastrointestinal (UGI) tract gastrointestinal stromal tumor (GIST) has evolved significantly over the past two decades. For GIST size smaller than 5 cm, laparoscopic resection has become the current standard. To avoid postoperative gastric deformity and preserve gastric function, laparoscopic endoscopic cooperative surgery (LECS) was developed and various modifications have been reported and utilized successfully.

Background: Adding intraperitoneal paclitaxel (IP-PTX) to paclitaxel/5-fluoropyrimidine has shown promising results in patients with gastric cancer peritoneal metastases (GCPM) but has not been studied with standard-of-care platinum/fluoropyrimidine combinations. Our goal to was evaluate IP-PTX with capecitabine/oxaliplatin (XELOX) in GCPM.

Methods: Forty-four patients with GCPM received IP PTX (40 mg/m, Days 1, 8), oral capecitabine (1000 mg/m twice daily, Days 1-14) and intravenous oxaliplatin (100 mg/m, Day 1) in 21-day cycles.

Sleep spindles are key electroencephalogram (EEG) oscillatory events that occur during non-rapid eye movement (NREM) sleep. Deficits in sleep spindles are present in populations with sleep and neurological disorders, and in severe mental illness. Pharmacological manipulation of these waveforms is of growing interest with therapeutic potential in targeting spindle deficits relating to memory impairment.

Despite multidisciplinary treatment for patients with advanced gastric cancer, their prognosis remains poor. Therefore, the development of novel therapeutic strategies is urgently needed, and immunotherapy utilizing anti-programmed death 1/-programmed death ligand-1 mAb is an attractive approach. However, as there is limited information on how programmed death ligand-1 is upregulated on tumor cells within the tumor microenvironment, we examined the mechanism of programmed death ligand-1 regulation with a particular focus on interferon gamma in an in vitro setting and in clinical samples.

Trypsin-modulating oostatic factor (TMOF) is an effective mosquito larvicide, but information on its potential toxicity to non-target organisms is limited. To investigate this, triplicate groups of 10 were exposed to 0, 10, 50 or 100 mg/L nominal TMOF concentrations for 12 days. Tail moisture, crude protein, and hepatopancreatic glycogen/histopathology were unaffected, but increasing TMOF linearly decreased survival and growth.

Steroid-resistant nephrotic syndrome (SRNS) causes 15% of chronic kidney disease (CKD). Here we show that recessive mutations in FAT1 cause a distinct renal disease entity in four families with a combination of SRNS, tubular ectasia, haematuria and facultative neurological involvement. Loss of FAT1 results in decreased cell adhesion and migration in fibroblasts and podocytes and the decreased migration is partially reversed by a RAC1/CDC42 activator.

Background & Aims: It is not clear how the duration of upper endoscopy affects the detection of cancer or premalignant lesions that increase the risk for gastric cancer. We investigated whether the length of time spent performing esophagogastroduodenoscopy (EGD) affects the detection of important pathologic features of the stomach.

Methods: We collected data from 837 symptomatic patients, during a 3-month period in 2010, who underwent a first diagnostic EGD at a tertiary university hospital in Singapore.

Tin dioxide (SnO2) is a potential candidate to replace conventional titanium dioxide (TiO2) in dye-sensitized solar cells (DSSCs) because of its wider bandgap and higher electron mobility. However, SnO2 suffers from low band edge that causes severe backflow of electrons towards electrolyte (charge recombination). Herein, we demonstrate that gallium (Ga) doping can increase the band edge of SnO2, and we show that DSSCs using a Ga-doped SnO2 nano-cuboids based photoanode offer improved open circuit potential (~0.

Outcome body size of gastrostomy tube (g-tube)-fed children with chronic kidney disease (CKD) was investigated. CKD patients, stages 2-5, who had a g-tube inserted and removed between 1985 and 2007 were retrospectively reviewed (n=20) for anthropometrics, lab values, and steroid use from insertion to latest date. CKD patients never having had a g-tube placed (n=82) acted as the comparison population with similar data collection at start and end of the latest 5-year period.
