Introduction: Omicron is a highly divergent variant of concern (VOCs) of a severe acute respiratory syndrome SARS-CoV-2. It carries a high number of mutations in its spike protein hence;it is more transmissible in the community by immune evasion mechanisms. Due to mutation within S gene, most Omicron variants have reported S gene target failure (SGTF) with some commercially available PCR kits. Such diagnostic features can be used as markers to screen Omicron. However, Whole Genome Sequencing (WGS) is the only gold standard approach to confirm novel microorganisms at genetically level as similar mutations can also be found in other variants that are circulating at low frequencies worldwide. This Retrospective study is aimed to assess RT-PCR sensitivity in the detection of S gene target failure in comparison with whole genome sequencing to detect variants of Omicron. Methods: We have analysed retrospective data of SARS-CoV-2 positive RT-PCR samples for S gene target failure (SGTF) with TaqPath COVID-19 RT-PCR Combo Kit (ThermoFisher) and combined with sequencing technologies to study the emerged pattern of SARS-CoV-2 variants during third wave at the tertiary care centre, Surat. Results: From the first day of December 2021 till the end of February 2022, a total of 321,803 diagnostic RT-PCR tests for SARS-CoV-2 were performed, of which 20,566 positive cases were reported at our tertiary care centre with an average cumulative positivity of 6.39% over a period of three months. In the month of December 21 samples characterized by the SGTF (70/129) were suggestive of being infected by the Omicron variant and identified as Omicron (B.1.1.529 lineage) when sequence. In the month of January, we analysed a subset of samples (n = 618) with SGTF (24%) and without SGTF (76%) with Ct values Conclusions: During the COVID-19 pandemic, it took almost more than 15 days to diagnose infection and identify pathogen by sequencing technology. In contrast to that molecular assay provided quick identification with the help of SGTF phenomenon within 5 hours of duration. This strategy helps scientists and health policymakers for the quick isolation and identification of clusters. That ultimately results in a decreased transmission of pathogen among the community. 展开更多

BACKGROUND Heart failure(HF),a common cardiovascular condition,is characterized by significant morbidity and mortality.While traditional Chinese medicine(TCM)is often used as a complementary approach in HF management,systematic evalua-tions of its impact on clinical outcomes,TCM syndrome scores,and B-type natriuretic peptide(BNP)levels are lacking.This study fills this gap through a comprehensive analysis of randomized controlled trials(RCTs)focusing on TCM for HF treatment.It encompasses an assessment of methodological quality,a meta-analysis,and an evaluation of evidence quality based on established standards.The results offer crucial insights into the potential advantages and constraints of TCM in HF management.RCTs on TCM for HF treatment published since the establishment of the database were searched in four Chinese and English databases,including China National Knowledge Infrastructure,Wanfang,VIP Information Chinese Science and Technology Journal,and PubMed.Methodological quality was assessed for the included studies with the Cochrane risk-of-bias assessment tool,and the meta-analysis and publication bias assessment was performed with the RevMan5.3 software.Finally,the quality of evidence was rated according to the GRADE criteria.RESULTS A total of 1098 RCTs were initially retrieved.After screening,16 RCTs were finally included in our study,which were published between 2020 and 2023.These RCTs involved 1660 HF patients,including 832 in the TCM group[TCM combined with conventional Western medicine(CMW)treatment]and 828 in the CWM group(CWM treatment).The course of treatments varied from 1 wk to 3 months.TCM syndrome differentiation was analyzed in 11 of the included RCTs.In all included RCTs,outcome indicators included comprehensive clinical outcomes,TCM syndrome scores,and BNP levels.The meta-analysis results showed significant differences between the TCM and CWM groups in terms of comprehensive clinical outcomes[risk ratio=-0.54;95%confidence interval(CI)=-0.61,-0.47;P<0.00001],TCM syndrome scores[weighted mean difference(WMD)=-142.07;95%CI=-147.56,-136.57;P<0.00001],and BNP levels(WMD=-142.07;95%CI=-147.56,-136.57;P<0.00001).According to the GRADE criteria,RCTs where"TCM improves clinical comprehensive outcomes"were rated as low-quality evidence,and RCTs where"TCM reduces TCM syndrome scores"or"TCM decreases BNP levels"were rated as medium-quality evidence.CONCLUSION TCM combined with CWM treatment effectively improves comprehensive clinical outcomes and diminishes TCM syndrome scores and BNP levels in HF patients.Given the low and medium quality of the included RCTs,the application of these results should be cautious. 展开更多

The most common cause of intestinal failure is short bowel syndrome (SBS), occurring as a result of a small functional intestine length, usually less than 200 cm, leading to intestinal malabsorption. A 59-year-old female with a past medical history of Crohns disease status post total colectomy with ileostomy over 20 years ago came to the hospital due to progressive weakness. Despite medical management, the patient had high ileostomy output, leading to electrolyte disbalance, metabolic acidosis, dehydration, and progressive kidney decline. Due to the high dependence on continuous fluid supplementation, it was decided to place a port for parenteral hydration to maintain fluid replacements and homeostasis after discharge. Prompt initiation of parenteral fluid replacement and close follow-up on patients with ileostomy and intestinal failure is strongly recommended to avoid complications and prevent intestinal, liver, or kidney transplants. 展开更多

Introduction: Primary Sjögren’s syndrome (SS) is the most common connective tissue disease after rheumatoid arthritis and affects mostly women between 30 and 40 years of age with an estimated prevalence between 0.1% and 0.6%. This observation illustrates an incidental finding of a case of SS in a young female patient in a context of obstructive renal failure (ARF) due to uterine fibroids. Observation: This was a 31-year-old woman hospitalized for anuric AKI (Acute Kidney Injury) with a creatinine level of 1247 μmol/l. Her history included sickle cell disease A/C and an unoperated uterine fibroid diagnosed 3 years ago. Approximately 2 months before her admission, her symptomatology was made of dizziness, physical asthenia, vomiting, poly-arthralgia, morning rash, pollakiuria and oral dryness. Abdominal examination showed a painless transverse mass in the pelvis. Biological examination showed a CRP (C-reactive protein) level of 488 mg/l. The cytobacteriological examination of the urine was normal and the proteinuria was 1.35 g/24 hours. The CT scan showed kidneys measuring 110 mm on the right and 113 mm on the left associated with bilateral pyelo-caliceal dilatation on a large polymyomatous uterus of interstitial and submucosal type. Immunologically, the anti-nuclear factor, the rheumatoid factor and the anti-SSA antibodies were positive. The resumption of the interrogation within the framework of the research of the subjective dry syndrome to find a notion of intermittent xerophthalmia 4 months ago. The Schirmer test was positive in the left eye. The initial management consisted of a polymyomectomy after 3 sessions of hemodialysis. Background treatment combining prednisone 5 mg/day and methotrexate 20 mg/week was started in parallel with the use of artificial tears. The evolution after twelve (12) months of treatment was favorable with a complete disappearance of the signs dry syndrome and full recovery of renal function. Conclusion: SS can have an insidious evolution and remain stable for many years, hence its fortuitous discovery in this case of obstructive ARF on uterine fibroid. In this context we insist on the interest of the immunological assessment in a patient in period of genital activity with a significant proteinuria and non-specific extrarenal signs. 展开更多

BACKGROUND Post-hepatectomy liver failure(PHLF)is one of the main causes of postoperative mortality and is challenging to predict early in patients after liver resection.Some studies suggest that the postoperative serum phosphorus might predict outcomes in these patients.AIM To perform a systematic literature review on hypophosphatemia and evaluate it as a prognostic factor for PHLF and overall morbidity.METHODS This systematic review was performed according to preferred reporting items for systematic reviews and meta-analyses statement.A study protocol for the review was registered in the International Prospective Register of Systematic Reviews database.PubMed,Cochrane and Lippincott Williams&Wilkins databases were systematically searched up to March 31,2022 for studies analyzing postoperative hypophosphatemia as a prognostic factor for PHLF,overall postoperative morbidity and liver regeneration.The quality assessment of the included cohort studies was performed according to the Newcastle-Ottawa Scale.RESULTS After final assessment,nine studies(eight retrospective and one prospective cohort study)with 1677 patients were included in the systematic review.All selected studies scored≥6 points according to the Newcastle-Ottawa Scale.Cutoff values of hypophosphatemia varied from<1 mg/dL to≤2.5 mg/dL in selected studies with≤2.5 mg/dL being the most used defining value.Five studies analyzed PHLF,while the remaining four analyzed overall complications as a main outcome associated with hypophosphatemia.Only two of the selected studies analyzed postoperative liver regeneration,with reported better postoperative liver regeneration in cases of postoperative hypophosphatemia.In three studies hypophosphatemia was associated with better postoperative outcomes,while six studies revealed hypophosphatemia as a predictive factor for worse patient outcomes.CONCLUSION Changes of the postoperative serum phosphorus level might be useful for predicting outcomes after liver resection.However,routine measurement of perioperative serum phosphorus levels remains questionable and should be evaluated individually. 展开更多

In order to rectify the problems that the com- ponent reliability model exhibits deviation, and the evalu- ation result is low due to the overlook of failure propagation in traditional reliability evaluation of machine center components, a new reliability evaluation method based on cascading failure analysis and the failure influ- enced degree assessment is proposed. A direct graph model of cascading failure among components is established according to cascading failure mechanism analysis and graph theory. The failure influenced degrees of the system components are assessed by the adjacency matrix and its transposition, combined with the Pagerank algorithm. Based on the comprehensive failure probability function and total probability formula, the inherent failure proba- bility function is determined to realize the reliability evaluation of the system components. Finally, the method is applied to a machine center, it shows the following: 1) The reliability evaluation values of the proposed method are at least 2.5% higher than those of the traditional method; 2) The difference between the comprehensive and inherent reliability of the system component presents a positive correlation with the failure influenced degree ofthe system component, which provides a theoretical basis for reliability allocation of machine center system. 展开更多

In order to apply the performance-based seismic design, an engineer must first find out whether the column is expected to fail in shear before or after flexural yielding. According to column failure characteristics and failure mode of reinforced concrete column, the UW-PEER structure performance database was discussed and analyzed. In order to investigate the relevance of failure mode and factors such as longitudinal reinforcement ratio, transverse reinforcement ratio, hoop spacing to depth ratio, aspect ratio, shearing resistance demand to shear capacity ratio and axial load ratio, Fisher's discriminant analysis(FDA) of the above factors was carried out. A discriminant function was developed to identify column failure mode. Results show that three factors, i.e., Vp /Vn, hoop spacing to depth ratio and aspect ratio have important influence on the failure mode. The failure mode has less to do with longitudinal reinforcement ratio, transverse reinforcement ratio and axial load ratio. Through using these three factors and the model proposed, over 85.6% of the original grouped cases were correctly classified. The value of coefficient of Vp /Vn is the largest, which means that discriminant equation is most sensitive to the shearing resistance demand to shear capacity ratio. 展开更多

AIM: To assess the efficacy and safety of TECA type hybrid artificial liver support system (TECA-HALSS) in providing liver function of detoxification, metabolism and physiology by treating the patients with acute liver failure (ALF). METHODS: The porcine liver cells (1-2) x 10(10) were separated from the Chinese small swine and cultured in the bioreactor of TECA-BALSS at 37.0 degrees C and circulated through the outer space of the hollow fiber tubes in BALSS. The six liver failure patients with various degree of hepatic coma were treated by TECA-HALSS and with conventional medicines. The venous plasma of the patients was separated by a plasma separator and treated by charcoal adsorbent or plasma exchange. The plasma circulated through the inner space of the hollow fiber tubes of BALSS and mixed with the patients' blood cells and flew back to their blood circulation. Some small molecular weight substances were exchanged between the plasma and porcine liver cells. Each treatment lasted 6.0-7.0 h. Physiological and biochemical parameters were measured before,during and after the treatment. RESULTS: The average of porcine liver cells was (1.0-3.0) x 10(10) obtained from each swine liver using our modified enzymatic digestion method. The survival rate of the cells was 85%-93% by trypan blue stain and AO/PI fluorescent stain. After cultured in TECA-BALSS bioreactor for 6 h, the survival rate of cells still remained 70%-85%. At the end of TECA-HALSS treatment, the levels of plasma NH(3), ALT, TB and DB were significantly decreased. The patients who were in the state of drowsiness or coma before the treatment improved their appetite significantly and regained consciousness, some patients resumed light physical work on a short period after the treatment.One to two days after the treatment, the ratio of PTA increased warkedly. During the treatment, the heart rates, blood pressure, respiration condition and serum electrolytes (K(+), Na(+) and Cl(-)) were stable without thrombosis and bleeding in all the six patients. CONCLUSION: TECA-HALSS treatment could be a rapid, safe and efficacious method to provide temporary liver support for patients with ALF. 展开更多

BACKGROUND Liver resection is an effective treatment for benign and malignant liver tumors.However,a method for preoperative evaluation of hepatic reserve has not yet been established.Previously reported assessments of preoperative hepatic reserve focused only on liver failure in the early postoperative period and did not consider the long-term recovery of hepatic reserve.When determining eligibility for hepatectomy,the underlying pathophysiology needs to be considered to determine if the functional hepatic reserve can withstand both surgery and any postoperative therapy.AIM To identify pre-hepatectomy factors associated with both early postoperative liver failure and long-term postoperative liver function recovery.METHODS This study was a retrospective cohort study.We retrospectively investigated 215 patients who underwent hepatectomy at our hospital between May 2013 and December 2016.Early post-hepatectomy liver failure(PHLF)was defined using the International Study Group of Liver Surgery’s definition of PHLF.Long-term postoperative recovery of liver function was defined as the time taken for serum total bilirubin and albumin levels to return to levels of<2 mg/dL and>2.8 g/dL,respectively,and the time taken for Child-Pugh score to return to Child-Pugh class A.RESULTS Preoperative type IV collagen 7S was identified as a significant independent factor associated with both PHLF and postoperative long-term recovery of liver function.Further analysis revealed that the time taken for the recovery of Child-Pugh scores and serum total bilirubin and albumin levels was significantly shorter in patients with type IV collagen 7S≤6 ng/mL than in those with type IV collagen 7S>6 ng/mL.In additional analyses,similar results were observed in patients without chronic viral hepatitis associated with fibrosis.CONCLUSION Preoperative type IV collagen 7S is a preoperative predictor of PHLF and longterm postoperative liver function recovery.It can also be used in patients without chronic hepatitis virus. 展开更多
