Impact of hyperglycemia on tuberculosis treatment outcomes: a cohort study.

Hyperglycemia is prevalent and closely associated with pulmonary tuberculosis (PTB). This study aimed to investigate the effects of hyperglycemia on the outcomes of PTB treatment. This study comprised 791 patients with PTB in total. Patients with fasting plasma glucose levels of ≥ 6.1 mmol/L were diagnosed with hyperglycemia. Anthropometric and baseline demographic data were also collected. The treatment response was assessed based on clinical symptoms (sputum production, cough, chest pain, fever, hemoptysis, night sweats, loss of appetite, and fatigue), sputum smear, chest computed tomography (CT), and adverse gastrointestinal responses (vomiting, nausea, abdominal distension, diarrhea, and constipation). A generalized estimating equation (GEE) was used to evaluate these relationships. Hyperglycemia affected 266 (33.6%) of the 791 patients with PTB. In GEE analyses, patients with hyperglycemia exhibited a greater incidence of elevated tuberculosis (TB) scores (odds ratio (OR) 1.569; 95% CI 1.040-2.369), cough (OR 1.332; 95% CI 1.050-1.690), and night sweats (OR 1.694; 95% CI 1.288-2.335). Hyperglycemia was linked with a higher risk of positive sputum smears (OR 1.941; 95% CI 1.382-2.727). During therapy, hyperglycemia was also associated with an increased incidence of vomiting (OR 2.738; 95% CI 1.041-7.198), abdominal distension (OR 2.230; 95% CI 1.193-4.171), and constipation (OR 2.372; 95% CI 1.442-3.902). However, the CT results indicated that hyperglycemia did not affect pulmonary lesions in patients with TB. Patients with TB and hyperglycemia are at a higher risk of severe clinical manifestations, positive sputum smears, and adverse gastrointestinal effects and, therefore, the special situation of hyperglycemic patients should be considered in the prevention and treatment of TB.

Levonorgestrel intrauterine system and breast cancer risk: An updated systematic review and meta-analysis of observational studies.

Objectives: Levonorgestrel intrauterine sustained release system (LNG-IUS) is an intrauterine hormonal contraceptive device. Breast cancer (BC) was the most common type of cancer in women in the world in 2020. The relationship between LNG-IUS and BC is controversial. We conducted an updated meta-analysis (larger sample capacity and including Asian data) to explore whether LNG-IUS can increase the risk of BC. Study design: We performed a thorough review of peer-reviewed publications from January 2005 through November 2022 using combinations of search terms for BC risk and LNG-IUS in the PubMed, Cochrane, Embase, Science Direct, and Web of Science databases. Studies reporting BC risk estimates among users of LNG-IUS were included according to the PRISMA criteria. Two authors independently evaluated all studies identified from the databases using Endnote software, and a third author resolved disagreements. The quality of evidence was evaluated using the Newcastle‒Ottawa Scale (NOS). A funnel plot was generated to assess publication bias. Results: We identified 3029 studies; 12 studies were included in our systematic review, and 6 studies involving 261,221 women were included in our meta-analysis. Two subgroup analyses were performed for different study designs. A total of 190,475 women were included in the meta-analysis of cohort studies, and the results were RR = 0.80 (95% CI 0.57-1.11, Z = 1.33, P = 0.18 > 0.05). The meta-analysis of the case‒control studies included 70,746 women, and the results were OR = 1.38 (95% CI 0.98-1.94, Z = 1.85, P = 0.06 > 0.05). Conclusions: Evidence of an increased risk of BC was not observed among LNG-IUS users. Implications: There are inconsistencies in existing studies that prevent us from confirming whether LNG-IUS can increase the risk of BC. Our updated meta-analysis preliminarily suggested that LNG-IUS did not increase the risk of BC, providing evidence for more clinically safe use and thus providing a better choice for contraception.

Predictive value of monocyte to lymphocyte ratio,neutrophil percentage to albumin ratio for diabetic macular edema / 新乡医学院学报

Objective To investigate the value of monocyte to lymphocyte ratio(MLR)and neutrophil percentage to albumin ratio(NPAR)in predicting diabetic macular edema(DME).Methods One hundred and one diabetic retinopathy patients admitted to the Third Affiliated Hospital of Xinxiang Medical University from January 2018 to February 2023 were selected as the research subjects,and they were divided into DME group(n=56)and non-DME group(n=45)based on fun-dus examination results.The general data such as gender,age,course of diabetes and laboratory indicators were collected by consulting medical records.Fasting elbow venous blood was collected early in the morning of the next day after the diagnosis of DME in both groups,the monocytes(MONO)count,lymphocyte(LYM)count,white blood cell(WBC)count,percentage of neutrophils(NEUT),plasma albumin(ALB),glycosylated haemoglobin(HbA1c)were measured by full automatic blood routine analyzer,and MLR,NPAR were calculated.General information and laboratory indexes of patients in the two groups were compared,and risk factors for DME were analyzed by multivariate logistic regression,and receiver operator characteristic(ROC)curve was applied to evaluate the predictive value of MLR and NPAR for DME.Results The course of diabetes,MONO count,NEUT,MLR,NPAR,WBC count,and HbA1c level of patients between the DME group were significantly higher than those in the non-DME group(P＜0.05);there was no statistically significant difference in gender,age,LYM count,and ALB level of patients between the two groups(P＞0.05).Multivariate logistic regression analysis showed that increased levels of WBC,MLR,and NPAR were independent risk factors for the occurrence of DME(P＜0.05).The ROC curve showed that the best cut-off value of MLR was 0.192,and the area under the curve(AUC)for the prediction of DME was 0.729(95％confidence interval:0.631-0.826),with a sensitivity of 58.9％and a specificity of 82.2％;while the best cut-off value of NPAR was 1.404,and the AUC for predicting DME occurrence was 0.884(95％confidence interval:0.820-0.949),with a sensitivity of 75.0％and a specificity of 91.1％;the AUC of MLR and NPAP for predicting the occurrence of DME was 0.906(95％confidence interval:0.851-0.906),with a sensitivity of 69.6％and a specificity of 93.3％.With MLR＞0.192 as positive and NPAR＞1.404 as positive,the parallel test of MLR and NPAR predicted the occurrence of DME with a sensitivity of 87.5％,a specificity of 71.1％,and an accuracy of 80.2％;while the tandem test of MLR and NPAR predicted the occurrence of DME with a sensitivity of 46.4％,a specificity of 97.8％,and an accuracy of 69.3％.Conclusion Increased levels of MLR and NPAR are independent risk factors for the occurrence of DME and have certain predictive value for DME.The predictive value of combined MLR and NPAR test for DME is higher than that of separate test,and parallel experiment is more helpful for the early prediction of DME.

Very early stage detection of acute myocardial infarction by harmonic ultrasonic integrated backscatter.

To study the very early diagnosis of acute myocardial infarction (AMI) by harmonic imaging ultrasonic integrated backscatter (IBS). Thirty normal persons, 68 cases with AMI, of whom 28 cases were at the very early stage of acute myocardial infarction (in 2 h), and 40 cases with acute myocardial infarction (in 2 to 12 h) were examined by IBS and the cyclic variation of integrated backscatter (CVIB) with HP-5500 ultrasonic system in different segment (the segment of myocardial infarction and no myocardial infarction). In the segment of AMI of the very early stage (in 2 h) the IBS (dB) is much higher than that of the segment of no AMI (18.7 versus 8.3), p < 0.001, the CVIB (dB) are lower (6.1 versus 7.6), p < 0.001. But at that time there are no obvious changes in ECG. In the other 40 cases with AMI in 2 to 12 h, IBS in the segment of AMI is obviously higher than the normal person and no infarction segment in the same heart (21.3:8.3, 20.2:8.5) p < 0.05, but CVIB (dB) is obviously lower than the normal person and no infarction segment in the same heart (5.8:7.6, 5.9:9.4) p < 0.05 the changes of the ultrasonic is coincidence with ECG. IBS (dB) are very obvious just as in ECG. The result demonstrates that ultrasonic tissue characterization with harmonic imaging integrated backscatter can be used for diagnosis in the very early stage of AMI, and can judge the segment range of AMI and function of the whole heart.

Prenatal diagnosis and pregnancy outcome of fetuses with isolated echogenic bowel / 中华围产医学杂志

Objective:To investigate the clinical value of isolated fetal echogenic bowel (FEB) as an indicator for invasive prenatal diagnosis.Methods:This retrospective study enrolled 183 pregnant women who were diagnosed with isolated FEB and underwent invasive prenatal diagnosis in Fujian Maternity and Child Health Hospital from August 2013 to January 2021. Clinical data including the results of conventional karyotyping and chromosomal microarray analysis (CMA), cytomegalovirus (CMV) DNA loads in amniotic fluid and pregnancy outcomes were reviewed analyzed. Chi-square test was used for statistical analysis Results:Karyotyping was performed on all of the 183 fetuses and three (1.64%) aneuploidies (one case of trisomy 21, one trisomy 18 and one 47,XYY syndrome) were detected. One trisomy 21 and four pathogenic (P)/likely pathogenic (LP) copy number variation (CNV) were detected among 108 fetuses who received CMA. The detection rate of P/LP chromosomal abnormalities by CMA was higher than that by karyotyping, but there was no significant difference between them [4.63% (5/108) vs 0.93% (1/108), χ 2=1.54, P>0.05]. In addition, three cases of variants of uncertain significance (VOUS) were detected by CMA. CMV DNA loads of fetal cells in the amniotic fluid samples of the 166 cases were determined, and only one (0.6%) was positive (CMV DNA up to 7.01×10 6 copies/ml), and no abnormalities were found in karyotype analysis and CMA detection. A total of 176 cases were followed up, and among them only one case of intrauterine infection and seven cases (three aneuploidies and four P/LP CNV) of chromosomal abnormalities were terminated after genetic counseling. Three fetuses with VOUS and other 165 fetuses without chromosomal abnormalities had a good prognosis after birth. Conclusions:Isolated FEB may be the abnormal ultrasound finding in fetuses with chromosomal abnormalities or CMV infection. Prenatal genetic testing and the exclusion of intrauterine infection are important for management during pregnancy and prognosis assessment of FEB.

Investigation of iodine nutritional status of children aged 8 to 10 years in Xiamen City from 2017 to 2019 / 中华地方病学杂志

Objective:To learn about the iodine nutritional status of children aged 8 to 10 years in Xiamen City after the reform of salt industry system, and to provide scientific basis for reasonable prevention and control of iodine deficiency disorders.Methods:From 2017 to 2019, 6 districts were selected each year in Xiamen City 5 sampling districts were divided according to the oriation of east, west, south, north and center in each district. One town (street, hereinafter refered as to town) was selected from each sampling district. One primary school was selected from each town. For each primary school, at least 40 non-boarding children aged 8 to 10 years (age balanced, half male and half female) were selected. Edible salt samples in the households and random urine samples of children aged 8 to 10 years were collected, and salt iodine and urinary iodine contents were measured, while thyroid volume was examined by B-ultrasound.Results:From 2017 to 2019, the coverage rate of iodized salt in Xiamen City was 97.34% (1 206/1 239), 96.89% (1 214/1 253), and 93.33% (1 175/1 259), respectively; the consumption rate of qualified iodized salt was 96.13% (1 191/1 239), 95.61% (1 198/1 253), and 91.58% (1 153/1 259), respectively; the median urinary iodine was 182.90, 182.81, 164.00 μg/L, respectively. The prevalence of goiter of boys and girls was 1.01% (19/1 889) and 2.26% (42/1 862), respectively.Conclusions:After the reform of salt industry system, the iodine nutritional status of children aged 8 to 10 years is generally at an appropriate level in Xiamen City. However, the consumption rate of qualified iodized salt is reduced, which increases the risk of iodine deficiency for residents. Therefore, we should strengthen the propaganda of scientific iodine supplement, maintain a high consumption rate of qualified iodized salt, and prevent the harm of iodine deficiency.

Prenatal ultrasonographic manifestations and genetic analysis of eight fetuses with 16p11.2 microdeletions / 中华医学遗传学杂志

OBJECTIVE@#To analyze the intrauterine phenotype and genotype of eight fetuses carrying a 16p11.2 microdeletion.@*METHODS@#5100 fetuses undergoing routine prenatal diagnosis were subjected to single nucleotide polymorphism-based microarray (SNP-array) analysis. Fetuses harboring a 16p11.2 microdeletion were analyzed for their ultrasonographic characteristics.@*RESULTS@#Eight fetuses were found to harbor a microdeletion in the 16p11.2 region. Among these, six had a typical 500-600 kb deletion, while the remaining two had an atypical 220 kb deletion at the distal part of 16p11.2. Four fetuses showed vertebral malformations, two had mild left ventriculomegaly, one had hydrocephalus, and one had pulmonary valve stenosis with regurgitation. The parents of five fetuses have accepted pedigree verification, and the results confirmed that the 16p11.2 microdeletions carried by fetuses all had a de novo origin.@*CONCLUSION@#The intrauterine phenotypes of fetuses carrying a 16p11.2 microdeletion may be variable, and the deletion can be effectively detected with the SNP-array assay.

Impact of confined placental mosaicism on non-invasive prenatal testing and pregnancy outcomes / 中华医学遗传学杂志

OBJECTIVE@#To assess the impact of confined placental mosaicism (CPM) on non-invasive prenatal testing (NIPT) and pregnancy outcomes.@*METHODS@#Copy number variation sequencing (CNV-seq) and single nucleotide polymorphism array (SNP-array) were carried out on placental specimen sampled from eight pregnancies with confirmed false-positive NIPT results. The impact of CPM on NIPT and pregnancy outcomes were analyzed based on the laboratory tests and clinical characteristics.@*RESULTS@#Five of the eight cases with false-positive NIPT results were proven to be CPM involving trisomy 9, 13, 21, 22, and X, respectively. The mosaic ratios for different placental regions have varied from 4% to 80%. Two fetuses with confirmed CPM showed fetal growth restriction (FGR) and additional ultrasound abnormalities, 1 fetus showed only FGR. The remaining two fetuses showed normal growth.@*CONCLUSION@#NIPT is highly sensitive to CPM, whilst CPM is an important cause for false-positive NIPT result. CPM may be associated with FGR. Investigation of the presence of CPM is important for both pre- and post-test genetic counseling and management of the pregnancy.

OBJECTIVE@#To analyze the prenatal ultrasonic characteristics and genetic features of 14 fetuses with chromosome 22q11 microdeletion syndrome (22q11DS).@*METHODS@#4989 fetuses were analyzed by using single nucleotide polymorphism array (SNP array) in the Fujian Maternal and Child Health Hospital from November 2016 to November 2019.@*RESULTS@#SNP array showed that 11 fetuses had classic 3 Mb microdeletion in 22q11 region, one fetus had 2.0 Mb microdeletion, and two fetuses had 1.0 Mb microdeletion. The 1.0 Mb microdeletion in 22q11 region contains SNAP29 and CRKL genes, which may increase the risk of congenital renal malformation and cardiovascular malformation.@*CONCLUSION@#Prenatal ultrasonic characteristics of fetuses with 22q11 microdeletion syndrome vary, and SNP array is a powerful tool to diagnose such diseases, which can provide accurate genetic diagnosis and enable prenatal diagnosis.

Progress in nutrition treatment for severe pneumonia / 中国医师杂志

Severe pneumonia is a common disease in intensive care unit (ICU), which is characterized by acute onset, poor prognosis, and can cause multiple systems dysfunction. For critical ill patients, in a state of stress, catabolism is increased, and nutritional risk is extremely high. Proper nutrition treatment can reduce the decomposition of own tissues in the stress period and supplement the protein and energy needed by the body′s metabolism. Therefore, the nutritional treatment of severe pneumonia patients is particularly important. This paper mainly reviews the nutritional literatures of severe pneumonia and critical ill patients in recent years, in order to provide more appropriate nutritional treatment for severe pneumonia patients.

An investigation of iodine nutritional status of children aged from 8 - 10 and pregnant women before and after adjustment of salt iodine concentration in Xiamen City / 中华地方病学杂志

Objective:To investigate the iodine nutritional status among children aged from 8 - 10 and pregnant women in Xiamen City before and after adjustment of salt iodine concentration, and scientifically evaluate the suitability of the new standard iodized salt adjustment policy for Xiamen City.Methods:In the pre-adjustment period (2011) and the post-adjustment period (2018), cross-sectional research methods and stratified cluster sampling methods were adopted in six districts of Xiamen City. The salt samples of residents and pregnant women, urine samples of children aged from 8 - 10 and pregnant women were collected to determine the iodine level; thyroid of children aged from 8 - 10 was examined. Changes in salt iodine, urine iodine and goiter prevalence before and after adjusting iodine content of salt were compared.Results:The median of salt iodine in residents after the adjustment (23.5 mg/kg) was significantly lower than that of before (28.9 mg/kg, Z = - 10.512, P < 0.05), the median of salt iodine in pregnant women after the adjustment (23.7 mg/kg) was significantly lower than that of before (29.2 mg/kg, Z = - 12.622, P < 0.05); the consumption rate of qualified iodized salt in residents after the adjustment (95.7%, 1 196/1 250) was significantly lower than that of before (97.1%, 1 608/1 656; χ 2 = 4.250, P < 0.05); before and after adjustment of salt iodine concentration, the consumption rate of qualified iodized salt in pregnant women was 94.7% (124/131) and 95.9% (579/604), respectively. No significant difference was found when comparing the consumption rate of qualified iodized salt in pregnant women (χ 2 = 0.015, P > 0.05). There was significant difference in median urinary iodine (from 204.2 to 183.9 μg/L, detected in 652, 1 250 urine samples, respectively) of children aged 8 - 10 years ( Z = - 3.583, P < 0.05); the difference of iodine nutritional status in pregnant women before and after adjustment of salt iodine concentration(130.2, 130.8 μg/L, detected in 132, 604 urine samples, respectively) was not significant ( Z = - 1.715, P > 0.05). The thyroid goiter rate of children aged 8 - 10 years had reduced from 1.1% (14/1 239) to 0.2% (2/1 253), the difference was statistically significant (χ 2 = 9.195, P < 0.05). Conclusions:As a whole, the measure of control and prevention of iodine deficiency disorders through iodized salt is implemented well in Xiamen City. After adjustment of salt iodine concentration, the iodine status of children aged from 8 to 10 is adequate, but the pregnant women has showed iodine deficiency.

Effects of sedative drugs on diaphragm activity and the timing of extubation in elderly patients after elective surgery / 中华老年医学杂志

Objective:To investigate the effects of sedatives on the activity of the diaphragm assessed by ultrasound and the timing of extubation in elderly patients after elective surgery.Methods:All 60 eligible elderly patients were randomly divided into three groups: the propofol group, the midazolam group and the control group(n=20, each group). Remifentanil was used in the three groups to keep the Critical Care Pain Observation Tool(CPOT)score less than 3.Patients in the propofol and midazolam groups were given propofol and midazolam sedation respectively, and the Richmond Agitation Sedation Scale(RASS)score was maintained at -2.Diaphragmatic activity was measured, the time from the end of the operation to extubation was recorded, and delirium was evaluated, and the above results were compared with those of the control group, which did not receive sedatives.Results:The activity of the diaphragm was lower in the propofol and midazolam groups than in the control group[(1.10±0.12)cm, (1.17±0.30)cm vs.(1.63±0.25)cm, F=30.170, P=0.000], and there was no significant difference between the propofol group and the midazolam group( t=25.340, P=0.615). There was no significant difference in duration of extubation among the propofol, midazolam and control groups[(1.41±2.08)d, (1.25±1.53)d vs.(1.19±1.40)d, F=0.089, P=0.915]. The incidence of delirium was higher in the midazolam group than in the propofol and control groups[55.0%(11/20), 20.0%(4/20) vs.15.0%(3/20), χ2=5.230, P=0.022, χ2=7.030, P=0.008)], but the difference between the propofol group and control group was not statistically significant( χ2=0.170, P=0.677). Conclusions:The application of sedatives after elective surgery has an effect on the activity of the diaphragm in elderly patients, and the effects of propofol and midazolam are similar.However, propofol and midazolam have no influence on the duration of extubation in elderly patients after elective surgery.Compared with propofol, midazolam increases the incidence of delirium in elderly patients after elective surgery.

Electroacupuncture and nerve and tendon gliding exercises can relieve mild to moderate carpal tunnel syndrome / 中华物理医学与康复杂志

Objective To observe the effect of electroacupuncture and nerve and tendon gliding exercises on mild to moderate carpal tunnel syndrome.Methods Forty patients with mild to moderate carpal tunnel syndrome were randomly divided into an observation group and a control group,each of 20.Both groups were given neurotrophic drugs.The observation group was additionally provided with electroacupuncture and nerve and tendon gliding exercises,while the control group was given routine health education for 4 weeks.The Boston carpal tunnel syndrome questionnaire (BCTQ),a visual analogue scale (VAS),thumb and middle finger to wrist motor conduction velocity (MCV),sensory nerve action potentials (SNAPs),median nerve distal motor latency (DML) and the amplitude of compound muscle action potential (CMAP) of the musculi abductor pollicis brevis were evaluated.Results There were no significant differences in any of the measurements between the two groups before the treatment.After four weeks of treatment,significantly better improvement was observed in the average SCV of the thumb and wrist,the SCV of the digitus medius and wrist,the SNAP of the thumb and wrist,the SNAP of the digitus medius and wrist,the DML of the nervus medianus and the CMAP of the abductor pollicis brevis in the observation group compared to before the treatment and compared to the control group.Moreover,there was a significant decrease in the observation group's average BCTQ symptom score and function score and in their VAS ratings.However,in the control group significant differences were only found in the average SCV of the thumb and wrist,the DML of the nervus medianus and in their VAS ratings.Conclusions Electroacupuncture and nerve and tendon gliding exercises can significantly relieve symptoms and restore hand function.They are worth applying in clinical practice.
