A systematic review and meta-analysis on the effect of goal-directed fluid therapy on postoperative outcomes in renal transplantation surgeries.

Introduction: This systematic review and meta-analysis investigated the impact of intraoperative goal-directed therapy (GDT) compared with conventional fluid therapy on postoperative outcomes in renal transplantation recipients, addressing this gap in current literature.

Method: A systematic search of patients aged ≥18 years who have undergone single-organ primary renal transplantations up to June 2022 in PubMed, Embase, Scopus and CINAHL Plus was performed. Primary outcome examined was postoperative renal function.

Predicting new-baseline glomerular filtration rate (NBGFR) after donor nephrectomy: validation of a split renal function (SRF)-based formula.

Background: Accurate prediction of post-donor nephrectomy (DN) glomerular filtration rate is potentially useful for evaluating and counselling living kidney donors. Currently, there are limited tools to evaluate post-operative new-baseline glomerular filtration rate (NBGFR) in kidney donors. We aim to validate a conceptually simple formula based on split renal function (SRF) previously developed for radical nephrectomy patients.

Findings from a Malaysian multicentre study on oropharyngeal squamous cell carcinoma.

Background: In addition to the conventional aetiologic agents of oropharyngeal squamous cell carcinoma (OPSCC) such as tobacco usage, alcohol consumption and betel quid usage, it has been established that a proportion of OPSCC are driven by persistent oncogenic human papillomavirus (HPV) infections. Currently, there is a lack of data on the burden of HPV- associated OPSCC in Asian countries including Malaysia.

Methods: A cross-sectional multicentre study with tissue analysis of Malaysian patients diagnosed with primary OPSCC within a five-year period, from 2015 to 2019 between 01/01/2015 to 31/12/2019 was undertaken.

Choosing the larger kidney on CT volumetry: a study on the early post-donation kidney function of living donors.

Background: Selecting the smaller kidney for donation has been advocated if there is a size difference of > 10% between the 2 kidneys but has never been prospectively evaluated. With increase in donor nephrectomies, it is important to evaluate this to minimize loss of renal function to donors.

Methods: 75 consecutive donor nephrectomy patients were included in our longitudinal study.

Use of metallic ureteric stents for chronic ureteric obstruction and its association with value-based care.

Introduction: We aimed to compare the real-world data and our clinical experience with metallic stents (MSs) and conventional polymeric stents (PSs) in the management of both malignant and benign chronic ureteric obstruction (CUO), in terms of clinical outcomes and costs.

Methods: Clinical data from our institution, including outcomes for all ureteric stents inserted for long-term management of CUO from all causes from 2014 to 2017, were retrospectively reviewed and compared between the MS and PS episodes.

Results: A total of 247 stents were placed in 63 patients with CUO over the 4-year study period.

Multi-photon microscopy for the evaluation of interstitial fibrosis in extended criteria donor kidneys: A proof-of-concept study.

Introduction: To evaluate the initial use of label-free second harmonic generation (SHG) imaging with two-photon excitation (2PE) auto-fluorescence in multiphoton microscopy (MPM) for the quantification of collagen/fibrosis on preimplantation biopsies of extended criteria donors (ECD).

Materials And Methods: Twenty preimplantation core biopsies were extracted from 10 donor kidney samples, of which originated from seven donors. Kidney Donor Profile Index (KDPI) and Remuzzi scores of biopsies were calculated.

The roles of gaze and head orientation in face categorization during rapid serial visual presentation.

Little is known about how perceived gaze direction and head orientation may influence human categorization of visual stimuli as faces. To address this question, a sequence of unsegmented natural images, each containing a random face or a non-face object, was presented in rapid succession (stimulus duration: 91.7 ms per image) during which human observers were instructed to respond immediately to every face presentation.

Effects of choral singing versus health education on cognitive decline and aging: a randomized controlled trial.

We conducted a randomized controlled trial to examine choral singing's effect on cognitive decline in aging. Older Singaporeans who were at high risk of future dementia were recruited: 47 were assigned to choral singing intervention (CSI) and 46 were assigned to health education program (HEP). Participants attended weekly one-hour choral singing or weekly one-hour health education for two years.

The use of negative-pressure wound therapy over a cultured epithelial autograft for full-thickness wounds secondary to purpura fulminans in an infant.

Purpura fulminans is a serious condition that can result in severe morbidity in the pediatric population. Although autologous skin grafts remain the gold standard for the coverage of partial- to full-thickness wounds, they have several limitations in pediatric patients, including the lack of planar donor sites, the risk of hemodynamic instability, and the limited graft thickness. In Singapore, an in-house skin culture laboratory has been available since 2005 for the use of cultured epithelial autografts (CEAs), especially in burn wounds.

Rhythmic timing in aging adults: On the role of cognitive functioning and structural brain integrity.

Here we asked whether impaired timing in older adults results from an aging clock or a more general brain and cognitive decline. Healthy aging adults (N = 70, aged 62-83 years) tapped to the beat of a periodic and a syncopated rhythm. Analyses focused on performance differences between rhythms (periodic-syncopated), which reduced the impact of timing unrelated processes.

Tryptophan-kynurenine ratio as a biomarker of bladder cancer.

Objectives: To investigate plasma and urinary kynurenine (KYN)-tryptophan (TRP) ratios in bladder cancer, expression of indoleamine 2,3-dioxygenase 1 (IDO1) in relation to tryptophan 2,3-dioxygenase (TDO2) in bladder tumour, and the correlation of KYN-TRP ratio with bladder tumour burden.

Methods: Metabotyping of the TRP-KYN metabolic axis was performed via a clinical case-control study. Expression of IDO1 and TDO2 was measured in human biopsied tissues.

Combination therapy of oxidised regenerated cellulose/collagen/silver dressings with negative pressure wound therapy for coverage of exposed critical structures in complex lower-extremity wounds.

Complex wounds with exposed critical structures such as tendon and bone are a conundrum in wound management, especially in the setting where the patient is not a suitable candidate for flap surgery. While the individual use of negative pressure wound therapy (NPWT) and oxidised regenerated cellulose (ORC)/collagen/silver (PROMOGRAN PRISMA) dressing has been described in the literature, there are little data on the efficacy of their combined use. In this study, we describe a novel technique of combining the use of NPWT and ORC/collagen/silver dressings to manage complex wound beds as an alternative management option for patients not suitable for reconstructive flap surgery.

Detection of Clinical Mesenchymal Cancer Cells from Bladder Wash Urine for Real-Time Detection and Prognosis.

Bladder cancer (BC) is a disease that requires lifelong surveillance due to its high recurrence rate. An efficient method for the non-invasive rapid monitoring of patient prognosis and downstream phenotype characterization is warranted. Here, we develop an integrated procedure to detect aggressive mesenchymal exfoliated bladder cancer cells (EBCCs) from patients in a label-free manner.

The Use of Acellular Dermal Matrix in Combination With Pedicled Buccal Fat Pad in Wide Cleft Palate Repair: A Case Report and Literature Review.

We describe a case of the combined use of acellular dermal matrix and pedicled buccal fat pad (BFP) in a wide U-shaped cleft palate repair. Acellular dermal matrix was used as a "patch" repair for the nasal mucosa defect as opposed to the conventional inlay graft. The advantages include reduced cost and a smaller avascular graft load.

Visceral obesity in Asian living kidney donors significantly impacts early renal function after donor nephrectomy.

Introduction: Obesity may be a risk factor for kidney donors to develop reduced renal function. The Framingham heart study suggested that visceral adipose tissue (VAT) confers a more adverse metabolic profile compared with subcutaneous adipose tissue (SAT). Asians tend to have a higher VAT composition and it is unclear if their kidney function is affected differently.

Robotic kidney autotransplantation in a porcine model: a procedure-specific training platform for the simulation of robotic intracorporeal vascular anastomosis.

Robotic-assisted kidney transplantation (RKT) with the Da Vinci (Intuitive, USA) platform has been recently developed to improve outcomes by decreasing surgical site complications and morbidity, especially in obese patients. This potential paradigm shift in the surgical technique of kidney transplantation is performed in only a few centers. For wider adoption of this high stake complex operation, we aimed to develop a procedure-specific simulation platform in a porcine model for the training of robotic intracorporeal vascular anastomosis and evaluating vascular anastomoses patency.

An Overview of the Use of Bromelain-Based Enzymatic Debridement (Nexobrid®) in Deep Partial and Full Thickness Burns: Appraising the Evidence.

Recent introduction of rapid bromelain-based enzymatic debridement has been increasingly popular in its use in nonsurgical debridement in deep partial and full thickness burns. We designed this study to evaluate the evidence suggested by current studies on the perceived benefits of using Nexobrid® compared with traditional surgical standard of care in burns wound debridement. A comprehensive search on electronic databases Pubmed, Embase, and Web of Science was done to identify studies published between 1986 and 2017 involving the use of Nexobrid® in deep partial and full thickness burns.

Preoperative Renal Volume: A Surrogate Measure for Radical Nephrectomy-Induced Chronic Kidney Disease.

Objectives: Surgically induced chronic kidney disease (CKD) has been found to have less impact on survival as well as function when compared to medical causes for CKD. The aim of this study is to evaluate whether preoperative remaining kidney volume correlates with renal function after nephrectomy, which represents an individual's renal reserve before surgically induced CKD.

Methods: A retrospective review of 75 consecutive patients (29.

Rearing in seawater mesocosms improves the spawning performance of growth hormone transgenic and wild-type coho salmon.

Growth hormone (GH) transgenes can significantly accelerate growth rates in fish and cause associated alterations to their physiology and behaviour. Concern exists regarding potential environmental risks of GH transgenic fish, should they enter natural ecosystems. In particular, whether they can reproduce and generate viable offspring under natural conditions is poorly understood.

Domestication and growth hormone transgenesis cause similar changes in gene expression in coho salmon (Oncorhynchus kisutch).

Domestication has been extensively used in agricultural animals to modify phenotypes such as growth rate. More recently, transgenesis of growth factor genes [primarily growth hormone (GH)] has also been explored as a rapid approach to accelerating performance of agricultural species. Growth rates of many fishes respond dramatically to GH gene transgenesis, whereas genetic engineering of domestic mammalian livestock has resulted in relatively modest gains.

Isolation, characterization and comparison of Atlantic and Chinook salmon growth hormone 1 and 2.

Background: Growth hormone (GH) is an important regulator of skeletal growth, as well as other adapted processes in salmonids. The GH gene (gh) in salmonids is represented by duplicated, non-allelic isoforms designated as gh1 and gh2. We have isolated and characterized gh-containing bacterial artificial chromosomes (BACs) of both Atlantic and Chinook salmon (Salmo salar and Oncorhynchus tshawytscha) in order to further elucidate our understanding of the conservation and regulation of these loci.

Parvicapsula minibicornis in anadromous sockeye (Oncorhynchus nerka) and coho (Oncorhynchus kisutch) salmon from tributaries of the Columbia River.

The myxosporean parasite Parvicapsula minibicornis is described from adult sockeye and coho salmon during spawning migrations in tributaries of the Columbia River in Canada and the United States. These observations extend the known distribution of this parasite from the Fraser River drainage basin. The parasite was identified in Columbia River salmonids using polymerase chain reaction (PCR) and by in situ hybridization, but unlike in Fraser River salmon, it was not observed in conventional histological preparations of the kidney.

Preferential PCR amplification of parasitic protistan small subunit rDNA from metazoan tissues.

A "universal non-metazoan" polymerase chain reaction (UNonMet-PCR) that selectively amplifies a segment of nonmetazoan Small Subunit (SSU) rDNA gene was validated. The primers used were: 18S-EUK581-F (5'-GTGCCAGCAGCCGCG-3') and 18S-EUK1134-R (5'-TTTAAGTTTCAGCCTTGCG-3') with specificity provided by the 19-base reverse primer. Its target site is highly conserved across the Archaea, Bacteria, and eukaryotes (including fungi), but not most Metazoa (except Porifera, Ctenophora, and Myxozoa) which have mismatches at bases 14 and 19 resulting in poor or failed amplification.
