vide great precision in electrode array positioning and decreased perioperative morbidity, combining the advantages of endoscopic approaches with those of the retroauricular route.Despite major advances in HIV testing, ultrasensitive detection of early infection remains challenging, especially for the viral capsid protein p24, which is an early virological biomarker of HIV-1 infection. Here, To improve p24 detection in patients missed by immunological tests that dominate the diagnostics market, we show a click chemistry amplified nanopore (CAN) assay for ultrasensitive quantitative detection. This strategy achieves a 20.8 fM (0.5 pg/ml) limit of detection for HIV-1 p24 antigen in human serum, demonstrating 20~100-fold higher analytical sensitivity than nanocluster-based immunoassays and clinically used enzyme-linked immunosorbent assay, respectively. Clinical validation of the CAN assay in a pilot cohort shows p24 quantification at ultra-low concentration range and correlation with CD4 count and viral load. We believe that this strategy can improve the utility of p24 antigen in detecting early infection and monitoring HIV progression and treatment efficacy, and also can be readily modified to detect other infectious diseases.Rare bleeding disorders (RBDs), including factor (F) I, FII, FV, FVII, combined FV and FVIII (CF5F8), FXI, FXIII and vitamin-K dependent coagulation factors (VKCF) deficiencies, are a heterogeneous group of hemorrhagic disorder with a variable bleeding tendency. RBDs are due to mutation in underlying coagulation factors genes, except for CF5F8 and VKCF deficiencies. FVII deficiency is the most common RBD with >330 variants in the F7 gene, while only 63 variants have been identified in the F2 gene. Most detected variants in the affected genes are missense (>50% of all RBDs), while large deletions are the rarest, having been reported in FVII, FX, FXI and FXIII deficiencies. Most were located in the catalytic and activated domains of FXI, FX, FXIII and prothrombin deficiencies. Understanding the proper molecular basis of RBDs not only can help achieve a timely and cost-effective diagnosis, but also can help to phenotype properties of the disorders.
Subepidermal moisture (SEM) scanning is a novel technology that measures changes in localised oedema. Accumulation of subepidermal oedema is associated with early tissue damage that may lead to a pressure injury.
The primary study objective was to observe the variations in sacral subepidermal oedema levels over a continuous period of 60-degree head of bed elevation positioning.
Healthy adult participants were recruited in this prospective observational study. Participants were positioned at 60-degree head of bed elevation for 120min and sacral SEM measurements were collected at baseline and in 20min increments.
A total of 20 participants with a mean age of 39.3 years (SD=14.7) were recruited. The mean SEM delta value increased 6.3% from 0.46 SEM delta at baseline to 0.49 SEM delta after 120min, however these differences are not statistically significant (p=.21). There were also no significant findings between SEM delta variations and demographic factors.
In a sample of healthy individuals, 120min of continuous loading with a 60-degree head of bed elevation did not lead to a significant change in sacral subepidermal oedema levels. Further research on the response of healthy adult tissue under external forces associated with different angles of head of bed positioning may further contribute to our understanding pressure injury prevention.

Five days after the kidney transplantation, the patient showed some bizarre behaviors after discharge, such as leaving home at night without any notice and jumping out of the moving car. The patient was hospitalized with a risk for suicidal ideation. The patient had no previous psychological problems other than a depressive mood disorder at 14 years of age.
Graft-derived cell-free DNA (GcfDNA) is a promising biomarker for comprehensive monitoring of allograft injury because it overcomes the limitations of traditional approaches. The aim of this study is to investigate the association between the outliers of GcfDNA at initial time post transplantation and short-term renal graft function.
A total of 230 recipients who underwent primary kidney transplantation were recruited in the study. For each recipient, 10 mL of peripheral blood were collected at day 1 post transplantation. Both of the GcfDNA fraction (%) and GcfDNA concentration (cp/mL) were determined using droplet digital PCR. The study was conducted in accordance with the 1964 Helsinki Declaration and its later amendments.
There were no values that fall outside of the lower extreme in both of the GcfDNA fraction and GcfDNA concentration, and the upper fence of GcfDNA fraction and GcfDNA concentration were 13.5% and 680 cp/mL, respectively. Selleck H-1152 Recipients with GcfDNA concentration ≥680 cp/mL had a statistically significant higher serum creatinine at day 7 post-transplantation, when compared with the other group (P=.008). The receiver operating characteristic analysis obtained an area under the curve value of 0.869 when using GcfDNA concentration to predict the risk of serum creatinine ≥400 μmol/L, an optimal cut-off value was indicated at 975 cp/mL with high sensitivity (87.5%) and specificity (85%).
Our results suggest that the quantification of GcfDNA at initial time after transplantation might be used as a novel strategy for predicting short-term risk of impaired kidney allograft function or delayed graft function.

Heart transplant (HTx) recipients constitute a group vulnerable to COVID-19 infection. Vaccination has been a turning point in the evolution of the pandemic. The objective was to analyze a series of HTx recipients with COVID-19 prior to vaccination and post vaccination.
Inclusion All HTx recipients diagnosed with COVID-19 (February 2020 to April 2022).
HTx younger than 16 years. They were subdivided into prevaccination period (February 2020 to February 2021) and postvaccination period (March 2021 to April 2022). They were classified into 3 groups according to severity. Group 1 mild symptoms without admission. Group 2 admission for nonsevere pneumonia. Group 3 severe pneumonia according to American Thoracic Society/Infectious Diseases Society of America criteria. The general therapeutic attitude before and after vaccination was similar in both groups.
A total of 65 HTx recipients have had COVID-19 to date (10.7% of the 374 HTx recipients alive). In the prevaccination period, 22 HTx recipients presentedd the percentage of hospitalization for nonsevere pneumonia slightly below the average hospitalization and mortality.
Currently, a high percentage of patients with congenital heart disease (CHD) reach adulthood. The consequence is that more and more patients will require a heart transplant (HTx) or heart-lung transplant (HLTx). The objective of the study was to analyze the evolution and temporary trend of the number of HTxs and HLTxs in patients with and without CHD.
We performed a retrospective analysis of all HTxs and HTLxs from a Spanish transplant hospital. Retransplant and other combined transplants were excluded. HTx and HLTx were divided into 2 groups (CHD or non-CHD). The number of procedures of each modality was grouped in 5 years.
A total of 930 HTxs were analyzed between 1987 and 2020; 36 were CHD (18 HTxs and 18 HLTxs). HTx and HLTx in CHD showed a growing progressive trend, probably because of the greater number of these patients who reach adulthood and finally develop advanced heart failure. HTx in patients without CHD showed a very high rise in the first decade, reaching the maximum peak around the year 2000, with a poststabilization trend or even progressive reduction in the number of procedures. HLTx in patients without CHD showed a marked ascent during the first decade with a peak around 2005 and subsequent significant decline in recent years practically in disuse, probably because of the possibility of circulatory assistance in the case of right ventricular failure.
The number of HTxs and HLTxs in CHD has a progressive rise. The number of HTx in patients without CHD remains relatively stable. HLTx in patients without CHD shows a marked decrease.

Mounting evidence in recent years has demonstrated that the number of obese adolescents has continued to rise. Obese adolescents are more likely to be diagnosed with type 2 diabetes, which causes additional harm. This study aimed to compare the clinical outcomes of bariatric surgery and medical treatment.
We conducted a multicenter, nonrandomized, retrospective study on 202 obese adolescents with type 2 diabetes who received surgery or medical treatment in three hospitals from 2017 to 2019. We analyzed the effects of surgery and medical treatment in terms of weight loss, glycemic control and the remission of type 2 diabetes. Propensity score matching was conducted to balance the confounding factors.
Among the 202 adolescents, 109 adolescents underwent surgery, and the remaining 93 adolescents received nonsurgical treatment. Both in the entire cohort and in the propensity-score matching cohort, the mean body mass index (BMI) and total weight in the surgery group notably decreased. Similarly, the effect of surgery on glycemic control (with respect to HBG, HbA1c, HOMA-IR) was superior to that of medical treatment. In the surgery group, the remission rate of diabetes was 76.1% in the entire cohort and 80.5% in the matched group, which was significantly higher than that in the control group (6.5% and 5.7%, respectively). In addition, LRYGB had better effects on weight loss and glycemic control than LSG.
Bariatric surgery is more effective in the control of weight loss and type 2 diabetes than medical treatment. The effects between different types of bariatric surgeries remain to be further investigated, and longer follow-up times are needed.

Postoperative nausea and vomiting are regarded as a serious concern after thyroidectomy. Electroacupuncture shows the potential to reduce general anesthesia-related side effects. The aim of this study was to evaluate the efficacy of electroacupuncture in preventing postoperative nausea and vomiting that commonly occurs in patients after thyroidectomy.
This study was a prospective randomized controlled trial with a two-arm, patient blind structure. Sixty-four participants were randomly assigned to the acupuncture (n=35) or control (n=29) group. Patients in the acupuncture group received electroacupuncture and intradermal press needles. The primary endpoint was the incidence and severity of postoperative nausea and vomiting, and secondary endpoints were the length of hospital stay, pain severity, and postoperative in-hospital morbidity.
The total incidence of postoperative nausea and vomiting was 40.6% (26/64). There was no difference in the incidence between the control (10/29, 34.5%) and acupuncture (16/35, 45.
