RESUMEN
Disseminated Cryptococcosis infection typically occurs in immunocompromised patients, often manifested as pneumonia or meningoencephalitis. Cases with involvement of either prostate or adrenal glands are less frequent. We describe a case of an immunocompromised 62-year-old man with new-found Idiopathic CD4 + T lymphocytopenia who presented with urinary irritation symptoms followed by headache. The patient was finally diagnosed as disseminated cryptococcosis of prostate, adrenal gland involvement with the help of combining histopathology of formalin-fixed, paraffin-embedded tissue with metagenomic next-generation sequencing technique to identify C neoformans sensu stricto in prostate, adrenal gland tissues. Clinicians should be aware of atypical presentations of cryptococcal disease. In this case of cryptococcosis in immunocompromised patients, we find that cryptococcosis can affect varied organs simultaneously and should be considered in the differential of infectious diseases. And mNGS technology helps to confirm the diagnosis.

BACKGROUND:Repetitive magnetic stimulation of either S3 nerve root or M1 area can improve the urination function of patients with urinary retention after spinal cord injury,but there are few reports on the repetitive magnetic stimulation of both sites in patients with urinary retention after spinal cord injury. OBJECTIVE:To observe the effect of repetitive magnetic stimulation of both S3 nerve root and M1 area on urinary retention after spinal cord injury. METHODS:Forty patients with urinary retention after spinal cord injury were enrolled and were randomly divided into two groups(n=20 per group):group A(repetitive magnetic stimulation in both S3 nerve root and M1 area)and group B(repetitive magnetic stimulation in the S3 nerve root and sham stimulation in the M1 area).Patients in both groups were given 4-week repetitive magnetic stimulation based on conventional bladder function intervention.The stimulation time and duration of treatment were same in both groups,with a treatment time of 21 minutes daily,5 days per week,for 4 weeks in total.The urination diary and urodynamics were compared between two groups. RESULTS AND CONCLUSION:Before treatment,there were no statistically significant differences in the average daily catheterization times,average daily catheterization volume,average single urinary volume,urinary storage period(maximum bladder volume,bladder pressure),and urinary voiding period(detrusor pressure,residual urine volume)between the two groups(P>0.05).After 4 weeks of treatment,the average daily catheterization times in group A were lower than before treatment(P<0.05),while the average single urination volume in group A was higher than that before treatment(P<0.05);and the average daily catheterization times in group B were lower than before treatment(P<0.05).After 4 weeks of treatment,the average daily catheterization times in group A were lower than those in group B,and the average single urination volume was higher than that in group B(P<0.05).After 4 weeks of treatment,the maximum bladder volume and detrusor pressure during urination were increased in both groups compared with before treatment(P<0.05),while the bladder pressure and residual urine volume at the maximum volume of the two groups were decreased compared with those before treatment(P<0.05).Compared with group B,the maximum bladder volume and detrusor pressure during urination were higher in group A,while the bladder pressure and residual urine volume at maximum volume were lower in group A(P<0.05).To conclude,two treatments can both improve the urination function of patients with urinary retention after spinal cord injury,and repetitive magnetic stimulation of both S3 nerve root and M1 area is superior to repetitive magnetic stimulation of S3 nerve root alone.Repetitive magnetic stimulation of both S3 nerve root and M1 area can effectively improve the urination function of patients with urinary retention after spinal cord injury.
RESUMEN
Objective:To study the clinical characteristics of congenital esophageal atresia (CEA) and risk factors of mortality associated with esophageal repair (ER) surgery.Methods:From January 2010 to December 2022, patients diagnosed of CEA using chest and abdomen X-ray and esophagography in our hospital were retrospectively reviewed. The patients were assigned into ER group and non-ER group according to the treatments. The ER group was subgrouped into survival group and death group according to the prognosis. Clinical data and outcomes were collected and compared between the groups.Results:A total of 553 cases were enrolled. According to Gross classification, 29 patients (5.2%) were type A, 2 patients (0.4%) were type B, 504 patients (91.1%) were type C, 6 patients (1.1%) were type D and 11 patients (2.0%) were type E. One patient had simple transluminal septal atresia of the esophagus. 406 patients were in ER group and 147 in non-ER group. Compared with ER group, non-ER group had significantly higher incidences of preterm birth, low birth weight and overall malformations (all P<0.05). In ER group, 152 patients (37.4%) received open thoracic surgery (OTS), 243 (59.9%) had video-assisted thoracoscopic surgery (VATS) and 11 (2.7%) were VATS converted to OTS. Postoperative anastomotic leakage (PAL) occurred in 92 patients (22.7%) and 15 patients (3.7%) died after surgery. The median length of hospital stay was 23 (17, 36) d. Compared with the survival group, the death group had higher incidences of preterm birth, low birth weight, VATS converted to OTS, mechanical ventilation after ER, and shorter length of hospital stay (all P<0.05). After adjusted for birth weight, VATS converted to OTS ( OR=9.585, 95% CI 1.899-48.374) and mechanical ventilation after ER ( OR=7.821, 95% CI 1.002-61.057) were risk factors of mortality in ER patients. Conclusions:Non-ER patients have higher incidences of preterm birth, low birth weight and overall malformations than ER patients. VATS is the method of choice for CEA. Preterm birth, low birth weight, VATS converted to OTS and mechanical ventilation after ER are risk factors of mortality in ER patients.
RESUMEN
With the prolongation of peritoneal dialysis time, the peritoneum probably confronts structural and functional deterioration due to multiple factors, which will affect the efficiency of peritoneal dialysis. Clinically effective measures to protect peritoneal function are still lacking. This article reviewed studies in the last decade on protection of peritoneal function, which included strategies on dialysis prescription, medicine treatments for protection of peritoneal function, and non-medicine treatments such as far-infrared therapy and stem cell transplantation, to provide guidances for subsequent researches.

RESUMEN
Objective:To investigate the neurobiochemical metabolites of caudate nucleus and thalamus in patients with obsessive-compulsive disorder and their relationship with obsessive-compulsive symptoms.Methods:From April 2019 to January 2022 in Beijing Anding Hospital, totally 25 untreated patients with obsessive-compulsive disorder were recruited, and 20 healthy controls matched with gender, age and educational background were recruited for the study.The maps of neurobiochemical metabolites of patients and normal controls were collected by hydrogen proton magnetic resonance spectroscopy.With bilateral caudate nucleus and thalamus as brain regions of interest.The relative concentrations of N-acetylaspartic acid (NAA), glutamic acid (Glu) and γ-aminobutyric acid (GABA) were fitted by LCModel software.At the same time, the clinical symptoms of patients were evaluated with Yale-Brown obsessive-compulsive scale (Y-BOCS) and Hamilton anxiety scale (HAMA). SPSS 20.0 software was used for statistical analysis.Independent double sample t-test was used to compare the differences of different nerve biochemical metabolite concentrations between patients with obsessive-compulsive disorders and healthy controls.Pearson correlation analysis was used to explore the correlation between biochemical metabolite concentrations and clinical symptoms. Results:The Glu concentration in the left thalamus of patients with obsessive-compulsive disorder (3.97±0.41) was higher than that of the control group (3.66±0.55)( t=-2.11, P<0.05), while the NAA concentration was (4.87±0.47)lower than that of the control group (5.15±0.44)( t=2.05, P<0.05). The GABA concentrations in the right caudate nucleus (0.50±0.18) and thalamus (0.80±0.19) were lower than those in the control group ((0.63±0.23), (0.96±0.24))( t=2.08, 2.36, both P<0.05). Pearson correlation analysis showed that the Glu concentration in the left caudate nucleus of patients with obsessive-compulsive disorder was positively correlated with the total score of Y-BOCS( r=0.46, P<0.05). Spearman correlation analysis showed that Glu concentration in the right caudate nucleus was positively correlated with the total score of HAMA in patients with obsessive-compulsive disorder ( r=0.46, P<0.05). Conclusion:NAA, Glu and GABA metabolism in caudate nucleus and thalamus are abnormal in patients with obsessive-compulsive disorder, and Glu concentration is positively correlated with the severity of obsessive-compulsive and anxiety symptoms.
RESUMEN
Objective:To investigate the dosimetric effects of prone immobilization devices combined with a belly board (PIDBBs) in the intensity-modulated radiotherapy (IMRT) for gynecologic cancers.Methods:A total of 20 patients with cervical or endometrial cancer treated with radiotherapy in the Third Affiliated Hospital of Sun Yat-sen University from August 2020 to June 2021 were retrospectively analyzed. Two sets of body contours were outlined for each patient. One set of body contours did not contain the immobilization devices, and the other contour set included the immobilization devices. For each patient, doses were calculated for the two sets of contours using the same 7-field IMRT plan and were recorded as Plan without and Plan with. The dosimetric difference caused by the immobilization devices was assessed by comparing the parameter values in the dose-volume histograms (DVHs) and by plan subtraction. The Gafchromic EBT3 film and anthropomorphic phantom were used to verify the calculated doses. Results:The target coverage and average dose of Plan with were lower than those of Plan without. Specifically, the V50 Gy, V49 Gy, and Dmean of planning target volume (PTV) decreased by 19.75%, 7.99%, and 2.54% ( t = 8.96, 10.49, 22.09, P < 0.01), respectively. The V40 Gy, V30 Gy, V20 Gy, V15 Gy, and Dmean of skins increased by 51.79%, 51.05%, 45.72%, 33.63% and 10.80% ( t = -2.54, -5.63, -15.57, -24.06, -13.88, P < 0.01), respectively. Doses to other organs at risk (OARs) showed no significant differences. As indicated by the EBT3 measurements, the doses to skins of the abdomen and pelvis on the anthropomorphic phantom increased by approximately 37.24% ( t = 10.86, P<0.01). Conclusions:Although PIDBBs can effectively reduce the low dose to the small intestine, the radiation attenuation caused by them can reduce the PTV coverage of radiotherapy plans and increase the doses to abdominal and pelvic skins sharply, especially for patients requiring irradiation of the groin and perineum.
RESUMEN
Objective:To explore the association between the intraperitoneal pressure (IPP) and clinical symptoms in peritoneal dialysis (PD) patients.Methods:It was a cross-sectional study. PD patients of Peking University First Hospital from January 1, to October 31, 2021, were enrolled according to the inclusion and exclusion criterion. The gold standard—Durand method was used to measure the IPP of PD patients for 2 L intraperitoneal volume, and clinical and laboratory data were collected. According to whether the IPP ≥ 18 cmH 2O or not, the participants were divided into elevated IPP group and normal IPP group. A self-designed semi-quantitative questionnaire was used to investigate the frequency and degree of five clinical symptoms, including abdominal distension, bloating, acid reflux, hiccup and chest tightness or suffrage, as well as the degree of symptom relief after emptying peritoneal dialysate. Pearson or Spearman correlation analysis was used to analyze the correlation between each variable and intraperitoneal pressure. Results:A total of 194 PD patients were enrolled, with age of (51.6±12.9) years old. Of them, there were 123 males (63.4%), 71 females (36.6%) and 60 patients (30.9%) with diabetes. The median dialysis vintage was 24.0 (10.0, 54.0) months. The IPP was (16.2±4.3) cmH 2O, and 70 (36.1%) patients had elevated IPP. Correlation analysis results showed that IPP was positively correlated with body weight ( r=0.23, P<0.001), body mass index ( r=0.41, P<0.001), body surface area ( r=0.15, P=0.030), triglyceride ( r=0.22, P=0.001), high-sensitivity C-reactive protein ( r=0.20, P<0.001), and negatively correlated with diabetes ( r=-0.14, P=0.034) and serum calcium ( r=-0.15, P=0.034). There was no significant correlation between IPP and the total frequency score of five clinical symptoms ( r=0.122, P=0.092). The frequency of stomach distension in elevated IPP group was significantly higher than that in normal IPP group ( P=0.002), and there were no significant differences in the degree and relief degree of stomach distension between the two groups (all P>0.05). There were no statistically significant differences in the extent, frequency and degree of relief of other four clinical symptoms between the two groups (all P>0.05). Conclusion:The increased IPP has little correlation with clinical symptoms, suggesting that it may be unreliable to adjust the infusion volume only by the subjective feeling of patients. It is necessary to monitor IPP as an objective variable.

Objective:To analyze the impact of implementing regular supervision and communication based on employee needs in the management of head nurses on improving the nursing practice environment, for reference for improving the nursing proctice environment.Methods:In December 2020 and January 2022, convenience sampling method was used to select 5 nursing unit nurses from a hospital which implemented regular supervision and communication based on employee needs(January to December 2021) as the research subjects. The survey was conducted using the Gallup Q12 questionnaire(Q12 questionnaire), which included 12 items from 4 dimensions: basic needs, head nurse support, team cooperation, and self growth. At the same time, a focus group interview method was made to interviews 10 survey subjects regarding their regular supervision and communication experiences.Results:A total of 165 survey subjects were included in this study, including 77 before and 88 after the implementation.The average total score of the Q12 questionnaire increased from 53.75 points before implementation of supervision communication to 56.96 points after implementation, with a statistically significant difference( P<0.05). The scores of the four dimensions of basic needs, head nurse support, team collaboration, and self growth increased from 4.59 points, 4.41 points, 4.50 points, and 4.45 points before implementation to 4.84 points, 4.69 points, 4.75 points, and 4.75 points after implementation, with statistical significances( P<0.05). The interview results showed that supervisory communication can create a humanistic care atmosphere, enhance team cohesion, enhance self-efficacy, improve work efficiency, solve problems in a timely manner, and improve nursing quality. Conclusions:Implementing regular supervision and communication based on employee needs can strengthen the connection between the head nurse and nurses, and enhance nurses′ recognition of basic needs, head nurse support, teamwork, and self growth. It was conducive to creating a good nursing practice environment, meeting the emotional and growth needs of nurses, and improving their job satisfaction.
RESUMEN
【Objective】 To analyze the clinical characteristics and prognostic differences between type Ⅰ and type Ⅱ papillary renal cell carcinoma (PRCC), and identify the prognosis-related independent predictors. 【Methods】 A total of 143 PRCC patients treated during Jan.2012 and Dec.2019 were involved, including 91 type Ⅰ patients and 52 type Ⅱ patients. The prognostic factors were analyzed with univariate and multivariate Cox regression analysis. The differences in cancer-specific survival (CSS) between the two groups were analyzed with Kaplan-Meier method and log-rank test. 【Results】 The patients’ age was 53.41±13.50 years. After a mean follow-up of 63.27±26.20 months, 14 patients died, and the overall CSS was 90.2%. The prognosis of type Ⅰ patients was better than type Ⅱ patients (94.5% vs. 82.7%, P=0.020). Cox regression suggested that PRCC subtype and stage were significantly associated with prognosis. There was no difference in prognosis between type Ⅰ and type Ⅱ patients in T1/T2 subgroup (P>0.05). However, in T3/T4 subgroup, type Ⅰ patients had a significant better prognosis than type Ⅱ patients (P=0.023), while the above trends were not observed in G1/G2 and G3/G4 subgroups (P>0.05). 【Conclusion】 PRCC subtype and stage are independent prognostic predictors. The impact of PRCC subtype on prognosis is mainly manifested in the subgroup of patients with T3 or higher stage.
RESUMEN
@#Conventional transcatheter aortic valve replacement is normally recommended with transthoracic echocardiography, and contrast agent mediated fluoroscopy under anesthesia to guide a better implantation of the transcatheter valve. However, iodine-containing contrast agent possibly damages the patient’s kidney, and even induces the acute kidney injury. We reported a 75-year-old patient diagnosed with severe aortic valve stenosis, moderate regurgitation, and chronic renal failure. We performed the aortic valve replacement under the guidance of fluoroscopy and transesophageal ultrasound without contrast agent. Seven days after surgery, the patient recovered well and discharged with alleviated aortic stenosis and fixed transcatheter aortic valve.
RESUMEN
Objective: To evaluate the clinical value of the MeltPro MTB assays in the diagnosis of drug-resistant tuberculosis. Methods: A cross-sectional study design was used to retrospectively collect all 4 551 patients with confirmed tuberculosis between January 2018 and December 2019 at Beijing Chest Hospital, Capital Medical University. Phenotypic drug sensitivity test and GeneXpert MTB/RIF (hereafter referred to as "Xpert") assay were used as gold standards to analyze the accuracy of the probe melting curve method. The clinical value of this technique was also evaluated as a complementary method to conventional assays of drug resistance to increase the detective rate of drug-resistant tuberculosis. Results: By taking the phenotypic drug susceptibility test as the gold standard, the sensitivity of the MeltPro MTB assays to detect resistance to rifampicin, isoniazid, ethambutol and fluoroquinolone was 14/15, 95.7%(22/23), 2/4 and 8/9,respectively; and the specificity was 92.0%(115/125), 93.2%(109/117), 90.4%(123/136) and 93.9%(123/131),respectively; the overall concordance rate was 92.1%(95%CI:89.6%-94.1%),and the Kappa value of the consistency test was 0.63(95%CI:0.55-0.72).By taking the Xpert test results as the reference, the sensitivity of this technology to the detection of rifampicin resistance was 93.6%(44/47), the specificity was100%(310/310), the concordance rate was 99.2%(95%CI:97.6%-99.7%), and the Kappa value of the consistency test was 0.96(95%CI:0.93-0.99). The MeltPro MTB assays had been used in 4 551 confirmed patients; the proportion of patients who obtained effective drug resistance results increased from 83.3% to 87.8%(P<0.01); and detection rate of rifampicin, isoniazid, ethambutol, fluoroquinolone resistance, multidrug and pre-extensive drug resistance cases were increased by 3.2%, 14.7%, 22.2%, 13.7%, 11.2% and 12.5%, respectively. Conclusion: The MeltPro MTB assays show satisfactory accuracy in the diagnosis of drug-resistant tuberculosis. This molecular pathological test is an effective complementary method in improving test positivity of drug-resistant tuberculosis.

Objective: To investigate the characteristics of pharmacokinetic (PK) and pharmacodynamic (PD) parameters of antibacterial agents in children with sepsis treated by extracorporeal membrane oxygenation (ECMO). Methods: In this prospective cohort study, 20 children with sepsis (confirmed or suspected) who were treated with ECMO and antimicrobial in the Department of Critical Medicine of Hunan Children's Hospital from March 2021 to December 2022 were enrolled as the ECMO group. Through therapeutic drug monitoring (TDM), the PK-PD parameters of antibacterial agents were analyzed. Twenty five children with sepsis in the same department who were treated with vancomycin but no ECMO at the same time were enrolled as the control group. The individual PK parameters of vancomycin were calculated by Bayesian feedback method. The PK parameters in the two groups were compared, and the correlation between trough concentration and area under the curve (AUC) was analyzed. Wilcoxon rank sum test was used for inter group comparison. Results: Twenty patients in the ECMO group, included 6 males and 14 females, with an onset age of 47 (9, 76) months. In the ECMO group, 12 children (60%) were treated with vancomycin, and the trough concentration was less than 10 mg/L in 7 cases, 10-20 mg/L in 3 cases, and >20 mg/L in 2 cases; AUC/minimum inhibitory concentration (MIC) (MIC=1 mg/L)<400 was in 1 case, 400-600 in 3 cases, and >600 in 8 cases. Among the 11 children (55%) who were treated with β-lactam antibiotics, there were 10 cases with drug concentration at 50% dosing interval (CT50)>4 MIC and 9 cases with trough concentration>MIC, both CT50 and trough concentration of cefoperazone reached the target. Among the 25 cases of control group, 16 were males and 9 females, with an onset age of 12 (8, 32) months. There was a positive correlation between vancomycin trough concentration and AUC (r2=0.36, P<0.001). The half-life of vancomycin and the 24-hour AUC (AUC0-24 h) in the ECMO group were higher than those in the control group (5.3 (3.6, 6.8) vs. 1.9 (1.5, 2.9) h, and 685 (505, 1 227) vs. 261 (210, 355) mg·h/L, Z=2.99, 3.50, respectively; both P<0.05), and the elimination rate constant and clearance rate was lower than those in the control group (0.1 (0.1, 0.2) vs. 0.4 (0.2, 0.5), 0.7 (0.5, 1.3) vs. 2.0 (1.1, 2.8) L/h, Z=2.99, 2.11, respectively; both P<0.05). Conclusion: The PK-PD parameters in septic children treated by ECMO varied with a longer half-life, higher AUC0-24 h, lower elimination rate constant and clearance rate.

The difference between sleep and wakefulness is critical for human health. Sleep takes up one third of our lives and remains one of the most mysterious conditions; it plays an important role in memory consolidation and health restoration. Distinct neural behaviors take place under awake and asleep conditions, according to neuroimaging studies. While disordered transitions between wakefulness and sleep accompany brain disease, further investigation of their specific characteristics is required. In this study, the difference is objectively quantified by means of network controllability. We propose a new pipeline using a public intracranial stereo-electroencephalography (stereo-EEG) dataset to unravel differences in the two conditions in terms of system neuroscience. Because intracranial stereo-EEG records neural oscillations covering large-scale cerebral areas, it offers the highest temporal resolution for recording neural behaviors. After EEG preprocessing, the EEG signals are band-passed into sub-slow (0.1-1 Hz), delta (1-4 Hz), theta (4-8 Hz), alpha (8-13 Hz), beta (13-30 Hz), and gamma (30-45 Hz) band oscillations. Then, dynamic functional connectivity is extracted from time-windowed EEG neural oscillations through phase-locking value (PLV) and non-overlapping sliding time windows. Next, average and modal network controllability are implemented on these time-varying brain networks. Based on this preliminary study, it appears that significant differences exist in the dorsolateral frontal-parietal network (FPN), salience network (SN), and default-mode network (DMN). The combination of network controllability and dynamic functional networks offers new insight for characterizing distinctions between awake and asleep stages in the brain. In other words, network controllability captures the underlying brain dynamics under both awake and asleep conditions.

Peritoneal dialysis (PD) catheter-related infections are important risk factors for catheter loss and peritonitis. 2023 International Society for Peritoneal Dialysis (ISPD) catheter-related infection recommendations have revised and clarified definitions and classifications of exit site infection and tunnel infection, such as cause-specific catheter-related infection, culture-negative catheter-related infection, refractory catheter-related infection, and infection- related catheter removal. A new target for the exit site infection rate should not exceed 0.40 episodes per year at risk. The recommendation about topical antibiotic cream or ointment to catheter exit site has been downgraded. New recommendations for exit site infection include clarified suggestion of exit site dressing cover and revised topical antibacterial agents as well as antibiotics treatment duration. In addition to catheter removal and reinsertion, new salvage options for catheter are suggested. The paper outlines the updated main content of the guide.
RESUMEN
Objective:To investigate the prognosis and risk factors for children diagnosed with all types of subaortic stenosis(SAS) who developed recurrent left ventricular outflow tract obstruction after surgical treatment.Methods:The study retrospectively included patients aged 0-18 years old who underwent open heart SAS surgery at Fuwai Hospital from 2016-2019. Children with hypertrophic obstructive cardiomyopathy were excluded. Detailed operative notes, medical records and ultrasound information, and follow-ups were extracted. Recurrent SAS was defined as left ventricular outflow tract gradient 30 mmHg(1 mmHg=0.133 kPa) 1 month after SAS surgical treatment.Results:A total of 137 children were included in this study. The medium age of children at the time of SAS surgery was 4.6 years old(3 months-17.8 years old). After a median follow-up of 4.36 years(3.2-5.7 years), a total of 30 patients developed recurrent LVOTO, with a recurrence rate of 21.9%, and 7(5.1%) underwent a second surgery. Compared to the non-recurrent group, children in the recurrent group were younger at the time of surgery( P=0.0443), had a smaller body surface area( P=0.0485), and a longer length of stay( P=0.0380). In Cox analysis, when only considering preoperative variables, the independent risk factor for LVOTO recurrence were a peak left ventricular outflow tract gradient higher than 50 mmHg( HR=5.25, P=0.001), a BSA less than 0.9( HR=2.5, P=0.023), and a length of SAS 5 mm( HR=2.29, P=0.050). When both preoperative and intraoperative variables were considered, preoperative peak left ventricular outflow tract gradient 50 mmHg( HR=4.91, P=0.002) and peeling from the aortic valve( HR=3.23, P=0.010) were independent risk factors for postoperative recurrence. Conclusion:Recurrent LVOTO after SAS surgical repair is common, and regular postoperative follow-up is crucial to evaluate whether a secondary intervention is required. Regular postoperative follow-up is needed for children at high risk.
RESUMEN
@#Objective To summarize the characteristics of children diagnosed with secondary subaortic stenosis after the surgical closure for ventricular septal defect and explore its potential mechanism. Methods We retrospectively collected patients aged from 0 to 18 years, who underwent ventricular septal defect closure and developed secondary subaortic stenosis, and subsequently received surgical repair from 2008 to 2019 in Fuwai Hospital. Their surgical details, morphological features of the subaortic stenosis, and the follow-up information were analyzed. Results Six patients, including 2 females and 4 males, underwent the primary ventricular septal defect closure at the median age of 9 months (ranging from 1 month to 3 years). After the first surgery, patients were diagnosed with secondary subaortic stenosis after 2.9 years (ranging from 1 to 137 months). Among them, 2 patients underwent the second surgery immediately after diagnosis, and the other 4 patients waited 1.2 years (ranging from 6 to 45 months) for the second surgery. The most common type of the secondary subaortic stenosis after ventricular septal defect closure was discrete membrane, which located underneath the aortic valve and circles as a ring. In some patients, subaortic membrane grew along with the ventricular septal defect closure patch. During the median follow-up of 8.1 years (ranging from 7.3 to 8.9 years) after the sencond surgery, all patients recovered well without any recurrence of left ventricular outflow tract obstruction. Conclusion Regular and persistent follow-up after ventricular septal defect closure combining with or without other cardiac malformation is the best way to diagnose left ventricular outflow tract obstruction in an early stage and stop the progression of aortic valve regurgitation.
RESUMEN
Objective@#To prospectively evaluate the efficacy of lauromacrogol injection for ablation (LIA) of benign predominantly cystic thyroid nodules and its related factors. @*Materials and Methods@#A total of 142 benign predominantly cystic thyroid nodules (median volume, 12.5 mL; range, 0.4– 156 mL) in 137 patients (male:female sex ratio, 36:101; mean age ± standard deviation [SD], 49 ± 13 years) were treated with LIA after being confirmed as benign via cytology. The volume reduction rate (VRR) of the nodules and cosmetic score were evaluated during follow-up at 1, 3, and 6 months after treatment and every 6 months thereafter. A VRR of ≥ 50% at the 12-month follow-up was considered to indicate effective treatment. The associations between the clinical factors and nodular ultrasound features, including the initial nodule volume, proportion of solid components, vascularity grade and ineffective treatment (VRR of < 50% at the 12-month follow-up), and regrowth were analyzed. @*Results@#All patients completed follow-up for at least 12 months. The average ± SD follow-up period was 32 ± 11 months (range, 12–54 months). The effective treatment rate was 73.2% (104/142), while the regrowth rate was 12.0% (17/142) at the last follow-up. Grade 2–3 intranodular vascularity in the solid components of the nodules was the only independent factor associated with ineffective treatment, with an odds ratio (reference category, grade 0–1) of 3.054 (95% confidence interval, 1.148–8.127) (p = 0.025). @*Conclusion@#LIA is an effective treatment for predominantly cystic thyroid nodules. Grade 2–3 intranodular vascularity in the solid components of nodules is the only independent risk factor for ineffective LIA.
RESUMEN
Objective:To explore the impact of narrative nursing on the meaning and quality of life in chemotherapy patients with advanced lung cancer.Methods:A total of 86 chemotherapy patients with advanced lung cancer hospitalized in the Oncology Department of Shanghai Pulmonary Hospital Affiliated to Tongji University from October 2020 to November 2021 were selected and divided into control group with 42 cases and narrative group with 44 cases by random number table method. The control group was treated with routine nursing of patients with tumor chemotherapy while the narrative group was implemented on narrative nursing intervention as well as routine nursing. A total of 12 to 14 times, each chemotherapy period was 7 times. The effect of the intervention was assessed by Meaning in Life Scale for Advanced Cancer Patients (MiLS)、Chinese Version of the Functional Assessment of Cancer Therapy-Lung(FACT-L 4.0) and Distress Thermometer (DT) before intervention, 1 week, 3 weeks and 2 months after intervention.Results:Forty cases in the control group and 42 cases in the narrative group were involved in the statistical analysis. Two months after intervention, the total score of MiLS, the score of the will to search for meaning, the meaning of life and satisfaction,existential frustration, life control, suffering tolerance and death acceptance in the control group were (98.60 ± 9.17), (14.90 ± 1.91), (13.38 ±2.62), (16.40 ± 2.73), (26.48 ± 3.19), (14.30 ± 1.68), (13.15 ± 3.07) points, which were significantly lower than those in the narrative group (112.02 ± 9.73), (16.45 ± 2.24), (16.31 ± 1.96), (19.40 ± 2.42), (28.76 ±3.48), (16.14 ± 1.82), (14.95 ± 2.39) points, and the difference were statistically significant ( t value were -6.42 --2.98, all P<0.01), and the main effect between groups and time were statistically significant ( F values were 2.76-24.47, all P<0.05). Two months after intervention, the total score of FACT-L, social/family status, emotional status, functional status and lung cancer specific module in control group were (90.75 ± 11.65), (18.58 ± 3.75), (15.65 ± 3.85), (13.48 ± 3.34), (22.00 ± 4.93) points, which were lower than those in the narrative group (102.12 ± 9.32), (20.36 ± 4.29), (18.10 ± 3.25), (16.74 ± 4.05), (24.80 ±3.83) points, the differences were statistically significant ( t values were-4.89--1.99, all P<0.05), and there was intergroup effect ( F values were 5.14-24.47, all P<0.05). Three weeks and 2 months after intervention, the psychological distress score of control group were (3.88 ± 2.73), (3.60 ± 2.19) points, which were significantly higher than the narrative group (2.52 ± 2.18), (1.90 ± 1.78) points, and the differences were statistically significant ( t=2.50, 3.85, both P<0.05), with a time, groups, interaction effect ( F=15.29, 15.86, 2.80, all P<0.05). Conclusions:Narrative nursing can effectively improve the meaning and quality of life and relieve psychological distress in chemotherapy patients with advanced lung cancer. It is worthy of clinical promotion.
RESUMEN
ObjectiveTo investigate the intestinal absorption characteristics of multi-index components in Danggui Buxuetang with drug absorption simulating system (DASS) established by everted intestinal sac model. MethodThe intestinal absorption solution at different time points after administration of Danggui Buxuetang was collected and detected by high performance liquid chromatography (HPLC), acetonitrile (A)-0.2% glacial acetic acid solution (B) was used as the mobile phase for gradient elution (0-16 min, 15%-23%A; 16-20 min, 23%-28%A; 20-25 min, 28%-30%A; 25-30 min, 30%A; 30-35 min, 30%-65%A; 35-45 min, 65%-95%A), the detection wavelength was 302 nm. HPLC fingerprint of intestinal absorption solution was established and the common peak was calibrated, and the relative cumulative absorption rate of each index component was calculated. The relative cumulative absorption curves of components were fitted with various mathematical models by DDSolver 1.0 to explore the absorption law of different components. ResultThe absorption process of C2 (calycosin-7-glucoside) and C6 in Danggui Buxuetang was in line with zero-order equation, C9 was best fitted by Weibull equation, and the remaining 7 components were in line with Makoid-Banakar equation. C1 with C2, C3, C5, C7 and C10, C2 with C5 and C7, C3 with C4, C5, C7 and C10, C4 with C6 and C10, C5 with C7, C6 with C10, C7 with C10, C8 with C9 were absorbed simultaneously during the absorption process. With the prolongation of time, the overall cumulative absorption rate of Danggui Buxuetang increased. At 120 min, the overall cumulative absorption rate of Danggui Buxuetang exceeded 38%, and reached 49.14% at 180 min. ConclusionTen ingredients in Danggui Buxuetang are absorbed in the jejunum, but absorption law of various components is different, which shows that the intestinal absorption of compound preparations of traditional Chinese medicine (TCM) has multiple characteristics. Intestinal absorption study of TCM compound preparations with chemical composition as the index can reveal some of its absorption law, but it is not complete.
