If 80% of these cases request tests, testing demand would exceed 1.4 million tests per week for five consecutive months. Demand was significantly lower in the low cough or fever incidence scenario, with 129,115 (95%CI 111,596 - 151,679) tests per day in January 2021, compared to 340,921 (95%CI 276,039 - 424,491) tests per day in the higher incidence scenario. Conclusions Our results show that national COVID-19 testing demand is highly dependent on background cough or fever incidence. This study highlights that the UK's response to the COVID-19 pandemic must ensure that a high proportion of people with symptoms request tests, and that testing capacity is sufficient to meet the high predicted demand.

The emergence of drug-resistant tuberculosis (TB), is a major menace to cast off TB worldwide. Line probe assay (LPA; GenoType MTBDRplus ver. 2) and Xpert MTB/RIF assays are two rapid molecular TB detection/diagnostic tests. To compare the performance of LPA and Xpert MTB/RIF assay for early diagnosis of rifampicin-resistant (RR) TB in acid-fast bacillus (AFB) smear-positive and negative sputum samples.

A total 576 presumptive AFB patients were selected and subjected to AFB microscopy, Xpert MTB/RIF assay and recent version of LPA (GenoType MTBDRplus assay version 2) tests directly on sputum samples. Results were compared with phenotypic culture and drug susceptibility testing (DST). DNA sequencing was performed with rpoB gene for samples with discordant rifampicin susceptibility results.

Among culture-positive samples, Xpert MTB/RIF assay detected Mycobacterium tuberculosis (Mtb) in 97.3% (364/374) of AFB smear-positive samples and 76.5% (13/17) among smear-negative samples, and the corresponding values for LPA test (valid results with Mtb control band) were 97.9% (366/374) and 58.8% (10/17), respectively. For detection of RR among Mtb positive molecular results, the sensitivity of Xpert MTB/RIF assay and LPA (after resolving discordant phenotypic DST results with DNA sequencing) were found to be 96% and 99%, respectively. Whereas, specificity of both test for detecting RR were found to be 99%.

We conclude that although Xpert MTB/RIF assay is comparatively superior to LPA in detecting Mtb among AFB smear-negative pulmonary TB. However, both tests are equally efficient in early diagnosis of AFB smear-positive presumptive RR-TB patients.

We conclude that although Xpert MTB/RIF assay is comparatively superior to LPA in detecting Mtb among AFB smear-negative pulmonary TB. However, both tests are equally efficient in early diagnosis of AFB smear-positive presumptive RR-TB patients.Objective To investigate the clinical characteristics, treatment and prognosis of TRPC6 variation induced children with steroid-resistant nephrotic syndrome (SRNS). Methods Clinical data of four patients with nephrotic syndrome carrying TRPC6 variations, who were admitted to the Department of Nephrology and Rheumatology, Children's Hospital of Shanghai from Jan. 2017 to Dec. 2019, was retrospectively analyzed. The literature search was conducted with "nephrotic syndrome" "child" and "TRPC6 variation" as keywords in China National Knowledge Infrastructure (CNKI), Wanfang, Weipu and Pubmed databases until August 2020. Results One of the four cases was male, and the others were female. Onset age ranged from 4-year-1-month to 12-year-2-month. They presented severe proteinuria, hypoalbuminemia or edema as a first symptom. Four patients had anemia, and two patients had secondary hyperparathyroidism, and one patient had renal atrophy. Renal pathology showed that one case was immune complex associated with glomeruloninuria and hypoproteinemia, 6 cases only showed proteinuria. BI-2865 The pathological type of 19 cases were FSGS, 2 cases were IgA nephropathy, 2 cases were minimal change disease, 1 case was collapse glomerulopathy, 1 case was C1q nephropathy, and 1 case was immune complex associated glomerulonephritis. Glucocorticoid therapy was ineffective in 18 cases, and calcineurin inhibitor was ineffective in 11 cases. The prognosis of the disease was poor. Renal failure occurred in 12 cases, and the time to end stage renal disease was from 4 months to 13.8 years. Conclusions TRPC6 variation can cause SRNS at a young age. FSGS is the primary pathological type of SRNS causing by TRPC6 variation. Glucocorticoid and immunosuppressive therapy are mostly ineffective. The disease progressed rapidly and the prognosis is poor.Objective To analyze the clinical, genetic characteristics and follow-up data of Chinese patients with hypophosphatasia (HPP). Methods A retrospective analysis was conducted on six children with HPP admitted to the Department of Endocrinology, Genetics and Metabolism in Beijing Children's Hospital from October 2010 to January 2019. Summarized the clinical and follow-up data of all six patients, as well as the pathogenic variants of five children. Results The serum alkaline phosphatase levels of all six children (five males and one female) were significantly reduced (2-49 U/L). The 6 patients aged from 2 months to 6 years and 4 months, 4 infantile HPP, 1 childhood HIP and 1 odonto HPP. The four patients with infantile HPP presented with anorexia, slow weight gain and hypercalcemia, whereas the one patient with childhood HPP and the other patient with odonto HPP had tooth loss. The patient with childhood HPP also manifested with motor dysfunction. Genetic testing was conducted for five patients and 4 unrelated Chinese families and revealed 10 variations in ALPL gene, including 7 missense variation, 1 insertion variation, 1 frameshift variation, 1 deletion variation.Of which 3 were novel (p.Y28C, p.268, F>L, p.A176V).One of the infantile patients lost follow-up and the other three deceased. The clinical conditions were much improved with medical intervention for patients with childhood, orodonto HPP. Conclusions While HPP patients with different ages of onset present with common features, the prognosis differ significantly. The prognosis is good for patients with childhood, orodonto HPP and poor for patients with infantile HPP. Genetic testing is the main method for definitive diagnosis.Objective To investigate the clinical characteristics, treatment and prognosis of children with acquired thrombotic thrombocytopenic purpura (TTP). link2 Methods The clinical manifestations, laboratory examination, treatment and prognosis of 5 children with acquired TTP hospitalized in Beijing Children's Hospital, Capital Medical University from January 2016 to July 2019 were analyzed retrospectively. Results There were 5 children with acquired TTP including 2 males and 3 females, with the onset age of 8.9(0.8-14.5) years, while 11 children with TTP in the same period. Thrombocytopenia and microangiopathic hemolytic anemia were found in all 5 patients. Only one patient had typical pentalogy of TTP, 3 patients had nervous system symptoms and 3 patients had fever, while renal impairment was relatively rare (1 case). Laboratory examination showed severe thrombocytopenia (7(4-14) ×109/L) and low level of hemoglobin (70(58-100)g/L) in all 5 children. Blood biochemical examination showed that total bilirubin (mainly indihe clinical manifestations are mainly thrombocytopenia and microangiopathic hemolytic anemia, the plasma ADAMTS 13 activity and inhibitor test are helpful for the diagnosis of acquired TTP. Plasma exchange and rituximab are effective treatment. This disease requires long-term follow-up.Objective To analyze the patients' clinical and genetic characteristics with pseudohypoparathyroidism (PHP) and investigate the correlation between clinical phenotypes and genotypes. Methods Twenty PHP patients were ascertained at Children's Hospital Zhejiang University School of Medicine from January 2011 to July 2020. Clinical manifestation, laboratory examination and gene test results were retrospectively analyzed. Results In these twenty patients, eighteen cases showed resistance to parathyroid hormone (PTH) and thirteen cases had Albright's hereditary osteodystrophy (AHO) phenotype. Gene abnormalities were found in all the twenty PHP patients, which included seven patients with GNAS gene variations (six frameshifts and one missense) and thirteen patients with GNAS gene methylation defects. Moreover, twelve children with both PTH resistance and AHO phenotype were clinically diagnosed as PHP-Ⅰa, meanwhile, seven carried GNAS variations and five had methylation abnormalities with a correct diagnosis of PHP-Ⅰb. link3 Conclusions Patients with AHO phenotype and PTH resistance may have a high genetic diagnosis rate. Because PHP-Ⅰb clinical phenotype may be similar to PHP-Ⅰa, early genetic detection is required for the differential diagnosis. In addition, children without PTH resistance should also be followed up regularly, which may help the early diagnosis.Objective To study the clinical characteristics and risk factors of post polypectomy electrocoagulation syndrome (PPECS) in children. Methods Clinical data of 23 children with PPECS in Children's Hospital Affiliated to Zhengzhou University from January 2015 to December 2019 were retrospectively analyzed. Additionally, 115 children without PPECS who had polypectomy performed by the same endoscopist at the same time were collected into the control group. The morbidity, clinical characteristics and therapeutic protocol were analyzed, and the risk factors of PPECS were analyzed by Logistic regression. Results Among the total 2 083 children who had endoscopic polypectomy with electrocautery, 23 children (1.1%) developed PPECS. All had abdominal pain and fever. The average age of the children with PPECS was (3.5±1.5) years, including 19 cases (82.6%) younger than 3 years. There were 18 cases with polyps larger than 25 mm (78.3%). The endoscopic operation time ((56±15) vs. (24±8) min, t=18.086, P less then 0.01), thtors of PPECS. Conclusions The clinical features of PPECS in children are fever, abdominal pain and leukocytosis after the procedure. The lesion size ≥ 25 mm, broad-based polyps and lesion located in the right hemicolon are the independent risk factors of pediatric PPECS.Objective To summarize the effect of Chinese Children's Cancer Group (CCCG) Wilms tumor (WT)-2015 protocol. Methods This was a prospective study. CCCG-WT-2015 protocol was revised on the basis of the CCCG-WT-2009 protocol. Clinical data of 288 children diagnosed with newly diagnosed kidney neoplasms in fourteen pediatric centers between September 2015 to December 2018 were summarized. The age of onset, distribution of pathological subtypes, staging, curative effect and prognostic factors of these children were analyzed. Kaplan-Meier method was used for survival curve and Log-Rank method was used for univariate analysis. Results Among 288 cases with kidney neoplasms, there were 261 cases of WT, including 254 cases (97.3%) with favorable histology (FH) WT and 7 cases (2.7%) with unfavorable histology WT (UFHWT). The 3 year events free survival (EFS) rate for FHWT and UFHWT were (88.9±2.1)% and (80.0±17.9)%, which were better than that in WT-2009 (81.2% and 71.7%). In the 96 cases of stage Ⅲ/Ⅳ FHWT with indications for radiotherapy, 76 cases received radiation, another 20 cases received M protocol chemotherapy (cyclophosphamide, etoposide, gentamycin, vincristine and adriamycin) instead of radiation. The 3 year EFS rate for these two groups were (84.7±4.3)% and (84.7±8.1)%(χ2=0.015, P=0.902). There were 22 renal clear cell sarcoma and 5 malignant rhabdoid tumor, 3 year EFS rate of them was (94.4±5.4)% and (20.0±17.9)%. Univariate analysis was performed for age, gender, pathological type, stage, whether rupture occurred during operation, whether complete remission (CR) occurred at the end of treatment and radiotherapy. Pathological types (χ2=44.329,P less then 0.01) and failure to achieve CR at the end of the treatment (χ2=49.459,P less then 0.01) were independent factor for predicting survival. Conclusion Compared with CCCG-WT-2009, treatment of renal tumors in CCCG-WT-2015 study yielded good survival outcome, which can be further applied.
