1Creation and control of high-dimensional multi-partite classically entangled light显示文摘Vector beams,non-separable in spatial mode and polarisation,have emerged as enabling tools in many diverse applications,from communication to imaging.This applicability has been achieved by sophisticated laser designs controlling the spin and orbital angular momentum,but so far is restricted to only two-dimensional states.Here we demonstrate the first vectorially structured light created and fully controlled in eight dimensions,a new state-of-the-art.We externally modulate our beam to control,for the frst time,the complete set of classical Greenberger-Horne-Zeilinger(GHZ)states in paraxial structured light beams,in analogy with high-dimensional multi-partite quantum entangled states,and introduce a new tomography method to verify their fidelity.Our complete theoretical framework reveals a rich parameter space for further extending the dimensionality and degrees of freedom,opening new pathways for vetorilly structured light in the classical and quantum regimes.Yjie Shen Iaac Nape Xilin Yang Xing Fu Mali Gong Darryl Naidoo Andrew Forbes 2021Light(Science & Applications)2021,10,5:4
2Diabetic nephropathy in Africa:A systematic review显示文摘AIM:To determine the prevalence and incidence of diabetic nephropathy in Africa.METHODS:We performed a systematic narrative review of published literature following the MOOSE Guidelines for Meta-Analysis and Systematic Reviewsof Observational Studies.We searched Pub MedMEDLINE for all articles published in English and French languages between January 1994 and July 2014 using a predefined strategy based on the combination of relevant terms and the names of each of the 54 African countries and African sub-regions to capture the largest number of studies,and hand-searched the reference lists of retrieved articles.Included studies reported on the prevalence,incidence or determinants of chronic kidney disease(CKD) in people with diabetes within African countries.RESULTS:Overall,we included 32 studies from 16 countries;two being population-based studies and the remaining being clinic-based surveys.Most of the studies(90.6%) were conducted in urban settings.Methods for assessing and classifying CKD varied widely.Measurement of urine protein was the most common method of assessing kidney damage(62.5% of studies).The overall prevalence of CKD varied from 11% to 83.7%.Incident event rates were 94.9% for proteinuria at 10 years of follow-up,34.7% for endstage renal disease at 5 years of follow-up and 18.4% for mortality from nephropathy at 20 years of followup.Duration of diabetes,blood pressure,advancing age,obesity and glucose control were the common determinants of kidney disease.CONCLUSION:The burden of CKD is important among people with diabetes in Africa.High quality data from large population-based studies with validated measures of kidney function are still needed to better capture the magnitude and characteristics of diabetic nephropathy in Africa.Jean Jacques N Noubiap Jashira Naidoo Andre P Kengne 2015World Journal of Diabetes2015,6,5:3
3A retrospective cohort study of body mass index and survival in HIV infected patients with and without TB co-infection显示文摘Background:High early morbidity and mortality following antiretroviral therapy(ART)initiation has been a distinguishing feature of ART programmes in resource limited settings(RLS)compared to high-income countries.This study assessed how well body mass index(BMI:kg/m^(2))correlated with survival among HIV infected patients with and without TB co-infection.Methods:We retrospectively evaluated clinical data from 1000 HIV infected patients,among whom 389 were also co-infected with TB,between January 2008 and December 2010,in KwaZulu-Natal,South Africa.Results:Among 948 patients eligible for analysis,15.7%(149/948)were underweight(<18.50),55.9%(530/948)had normal BMI(≥18.50-24.90),18.7%(177/948)were overweight(25.00-29.00)and 9.7%(92/948)were obese(≥30.00).Irrespective of TB status,underweight patients,had significantly higher risk of death compared to those with normal BMI at baseline(aHR=2.9;95%CI:1.5-5.7;P=0.002).Conclusions:Irrespective of TB co-infection,low BMI correlated with mortality in HIV infected patients.Trial registration:UKZN Biomedical Research Ethics Committee Reference number E 248/05,23 September 2005.Kogieleum Naidoo Nonhlanhla Yende-Zuma Stanton Augustine 2018Infectious Diseases of Poverty2018,7,1:3
4Umbilical cord blood stem cell treatment for a patient with psoriatic arthritis显示文摘Clinical and laboratory results document psoriatic arthritis in a 56-year old patient. The symptoms did not resolve with standard treatments(nonsteroidal anti-inflammatory drugs, steroids and methotrexate). TNF-alpha inhibitors(certolizumab pegol and adalimumab) were added to the treatment regime, with some adverse effects. A trial of human umbilical cord stem cell therapy was then initiated. The stem cells were enriched and concentrated from whole cord blood, by removal of erythrocytes and centrifugation. The patient received several infusions of cord blood stem cells, through intravenous and intra-articular injections. These stem cell treatments correlated with remission of symptoms(joint pain and psoriatic plaques) and normalized serologic results for the inflammatory markers C-reactive protein and erythrocyte sedimentation rate. These improvements were noted within the first thirty days post-treatment, and were sustained for more than one year. The results of this trial suggest that cord blood stem cells may have important therapeutic value for patients with psoriatic arthritis, particularly for those who cannot tolerate standard treatments.Margaret Coutts Rowena Soriano Rajendran Naidoo Habib Torfi 2017World Journal of Stem Cells2017,9,12:3
5Isolated free intra-abdominal fluid on CT in blunt trauma: The continued diagnostic dilemma显示文摘Purpose: The clinical significance of isolated flee fluid (FF) without solid organ injury on computed to- mography (CT) continues to pose significant dilemma in the management of patients with blunt abdominal trauma (BAT). Methods: We reviewed the incidence of FF and the clinical outcome amongst patients with blunt abdominal trauma in a metropolitan trauma service in South Africa. We performed a retrospective study of 121 consecutive CT scans over a period of 12 months to determine the incidence of isolated FF and the clinical outcome of patients managed in a large metropolitan trauma service, Results: Of the 121 CTs, FF was identified in 36 patients (30%). Seven patients (6%) had isolated FF. Of the 29 patients who had free fluid and associated organ injuries, 33 organ injuries were identified. 86% (25/ 29) of all 29 patients had a single organ injury and 14% had multiple organ injuries. There were 26 solid organ injuries and 7 hollow organ injuries. The 33 organs injured were: spleen, 12; liver, 8; kidney, 5; pancreas, 2; small bowel, 4; duodenum, 1. Six (21%) patients required operative management for small bowel perforations in 4 cases and pancreatic tail injury in 2 cases. All 7 patients with isolated FF were initially observed, and 3 (43%) were eventually subjected to operative intervention. They were found to have an intra-peritoneal bladder rupture in 1 case, a non-expanding zone 3 haematoma in I case, and a negative laparotomy in 1 case. Four (5?%) patients were successfully managed without surgical interventions. Conclusions: Isolated FF is uncommon and the clinical significance remains unclear. Provided that reli- able serial physical examination can be performed by experienced surgeons, an initial non-operative approach should be considered.Victor Y. Kong Damon Jeetoo Leah C.
