ABSTRACT

Objective To investigate the association between maternal food group intakes during pregnancy and the risk of infantile eczema in a Chinese population. Methods A prospective birth cohort study was conducted and 523 women were recruited at 20-28 weeks of pregnancy in Guangzhou from 2017 to 2018. A validated 81-item quantitative food frequency questionnaire was used to assess maternal dietary intakes during the past month. Food items were divided into ten food groups according to the Chinese Dietary Guidelines. Offspring were followed up at 6 months by the symptom questionnaire of eczema. Multivariate Logistic regression model was conducted to evaluate the association between maternal food group intakes during pregnancy and the risk of infantile eczema. Results The cumulative incidence of eczema at 6 months was 51.8%. Maternal consumption of poultry was higher in the eczema group (27.62±25.20 g/d) than the control group (22.03±22.63 g/d, P=0.022). Comparing to the lowest quantile (Q1), higher maternal intake of poultry (Q4) and fish (Q3) were significantly associated with an increased risk of infantile eczema (OR=2.71, 95% CI=1.24-4.81; OR=2.38, 95% CI=1.23-4.59, respectively) after multivariate adjustment. Conclusion Higher intakes of poultry or fish during pregnancy were associated with an increased risk of infantile eczema in Chinese population.

ABSTRACT

<p><b>BACKGROUND</b>Rheumatic diseases involve multiple organs that are affected by immunological mechanisms. Treatment with corticosteroids and immunosuppressive agents may also increase the frequency of infection. Cytomegalovirus (CMV) is a widespread herpes virus and a well-recognized pathogen, which causes an opportunistic and potentially fatal infection in immunocompromised patients. This retrospective study aimed to investigate the clinical and laboratory characteristics of CMV pneumonia in patients with rheumatic diseases after immunosuppressive therapy in a single center in Shanghai, China.</p><p><b>METHODS</b>Eight hundred and thirty-four patients with rheumatic diseases who had undergone CMV-DNA viral load tests were included, and the medical records of 142 patients who were positive for CMV-DNA in plasma samples were evaluated. GraphPad Prism version 5.013 (San Diego, CA, USA) was used to conduct statistical analysis. The correlation between CMV-DNA viral loads and lymphocyte counts was assessed using the Spearman rank correlation coefficient test. Significance between qualitative data was analyzed using Pearson's Chi-squared test. The cut-off thresholds for CMV-DNA viral load and lymphocyte count were determined by receiver operating characteristic (ROC) curve analysis.</p><p><b>RESULTS</b>One hundred and forty-two patients had positive CMV viral load tests. Of these 142 patients, 73 patients with CMV pneumonia were regarded as symptomatic, and the other 69 were asymptomatic. The symptomatic group received higher doses of prednisolone (PSL) and more frequently immunosuppressants than the asymptomatic group (P < 0.01). The symptomatic group had lower lymphocyte counts, especially CD4+ T-cells, than the asymptomatic group (P < 0.01). By ROC curve analysis, when CD4+ T-cell count was <0.39 × 109/L, patients with rheumatic diseases were at high risk for symptomatic CMV infection. The CMV-DNA load was significantly higher in the symptomatic patients than that in asymptomatic patients (P < 0.01; threshold viral loads: 1.75 × 104 copies/ml). Seven patients had a fatal outcome, and they had lower peripheral lymphocyte counts (P < 0.01), including CD4+ and CD8+ T-cells (P < 0.01).</p><p><b>CONCLUSIONS</b>When CD4+ T-cell count is <0.39 × 109/L, patients are at high risk for pulmonary CMV infection. Patients are prone to be symptomatic with CMV-DNA load >1.75 × 104 copies/ml. Lymphopenia (especially CD4+ T-cells), presence of symptoms, and other infections, especially fungal infection, are significant risk factors for poor outcome, and a higher PSL dosage combined with immunosuppressants may predict CMV pneumonia.</p>

ABSTRACT

Objective To assess the relationship between cardiovascular risk factors and osteoporosis. Methods 2202 women aged 50-73 years were included in this cross-sectional study from the communities in Guangzhou, from July 2008 to January 2010. Cardiovascular risk factors including age, years since menopause, physical activity, anthropometrics, body composition, blood pressure, fasting serum lipids, glucose and uric acid, intima-media thickness(IMT) of carotid artery were assessed. Ultrasonic bone density (speed of sound) at the radius and tibia were determined. Osteoporosis was defined as T-score≤-2.5. Common factors for the cardiovascular risk factors were extracted using the factor analysis method. Results Eight common factors representing obesity, lean mass, blood triglycerides and uric acid, cholesterol, age, blood pressure, IMT and physical activity were extracted. Data from the Multivariate logistic regression showed a dose-dependent association of greater scores of age and IMT factors and lower score of lean mass factor with the increased risk of osteoporosis at the radius and tibia. As compared with the bottom quartile, the OR (95%CI) of radius and tibia osteoporosis were 0.62 (0.44-0.88) and 0.62 (0.48-0.80) for lean mass factor, 4.02 (2.72-5.94) and 3.68(2.81-4.82) for age factor, 1.41 (1.00-2.00) and 1.54 (1.19-2.00) for IMT factors, respectively. Moreover, greater blood pressure score was associated with higher risk of radius osteoporosis while the higher obese score, was correlated with the increased risk of tibia osteoporosis. Conclusion The cardiovascular-related risk factors of greater IMT, obesity, blood pressure and lower lean mass scores were associated with increased osteoporosis risks while called for more concern among the Chinese women.

ABSTRACT

To report an unusual case of synchronous renal cell carcinoma and CNS lymphoma in a patient with autosomal dominant polycystic kidney disease [ADPKD]. A 58-year-old woman presented with progressive right hemiparesis of 2 months' duration. A brain CT scan revealed multiple enhanced lesions in the basal ganglia and the right occipital lobe. CMS lymphoma was confirmed by a stereotactic biopsy. Polycystic kidneys and a right renal mass were found incidentally. It was decided to treat the patient with cranial radiotherapy and chemotherapy first. The patient achieved complete remission of CMS lymphoma after 3 months, but the renal mass remained unchanged. A needle biopsy of the renal mass revealed renal cell carcinoma and unilateral nephrectomy was performed successfully. The patient remained in complete remission at 6-year follow-up. The patient was treated successfully with a combination of chemotherapy, radiotherapy, and unilateral nephrectomy. This report highlights the need for clinicians to remain alert to the possibility of double malignancies while caring for ADPKD patients, especially when multiple unexplained manifestations exist

ABSTRACT

Objective To explore the influence of occupational stress and negative life events that occur during pregnancy on different types of low birth weight (LBW). Methods 438 singleton LBW infants (birth weight of less than 2500 g and their pregnancy term from 28 to 42 weeks) were selected as case group, and they were further divided into symmetric LBW infants (337 cases) and asymmetric LBW infants (101 cases). According to situation of each LBW infant, a singleton with full term and normal birth weight was selected as control group matched by sex, pregnancy term, time during delivery and types of hospital.All of their mothers were inquired by well trained investigators on their socio-demographic characteristics, occupational stress, and negative life events that occurred in different pregnancy term. After controlling for mother's age, occupation,education level and family income, multinomial logistic regression was employed to asses the influence of occupational stress and negative life events on symmetric LBW and asymmetric LBW. Results Compared with those using low technical skills, mothers with high technical skill utilization significantly decreased the risk of laboring both symmetric LBW ( OR = 0.69, 95 % CI:0.49-0.98) and asymmetric LBW (OR = 0.53,95%CI: 0.31-0.89). Compared with those without exposure to negative life events, mothers with negative life event score ≥ 3 in the whole duration of pregnancy had significantly increased the risk of delivering symmetric LBW ( OR = 2.30, 95% CI : 1.08-4.88), mothers with negative life event score ≥3 in the middle three months of pregnancy, ≥3 in the last three months of pregnancy, = 2 and ≥3 in the whole duration of pregnancy had significantly increased the risk of delivering asymmetric LBW, and their OR (95 % CI ) was 8.85 (1.97-39.68), 3.80 ( 1.40-10.29 ),3.58(1.33-9.66) and 3.48 (1.32-9.13), respectively. Conclusion Occupational stress and negative life events might produce different influence on symmetric LBW and negative life events that occurr in the different terms of pregnancy had different impact on symmetric LBW and asymmetric LBW.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the reliability and validity of parent proxy-report scales of Pediatric Quality of Life Inventory Version 4.0 (PedsQL 4.0) Generic Core Scales, the Chinese Version.</p><p><b>METHODS</b>3493 school students aged 6-18 years were recruited using multistage cluster sampling method. Health-related quality of life was assessed using the above-mentioned PedsQL 4.0 scales. The internal consistency was assessed, using Cronbach's a coefficient, while its validity was tested through correlation analysis, t-test and exploratory factor analysis.</p><p><b>RESULTS</b>The internal consistency reliability for Total Scale Score (Cronbach's alpha = 0.90), Physical Health Summary Score (alpha= 0.81), and Psychosocial Health Summary Score (alpha= 0.89) were excellent. Six major factors were extracted by factor analysis which basically matched the designed structure of the original version accounting for nearly 66% of the variance. The total Scale Score significantly decreased by 3.5 to 13.3 (P < 0.05) in children and adolescents who had diseases including cold, skin hypersensitiveness, food allergy, courbature or arthralgia, breathlessness with a frequency of 6 times or more per year or had asthma as compared to those with lower frequency (< or = 5 times/y) of the diseases or without asthma. We found moderate to high correlations between items and the subscales. Correlation coefficients ranged between 0.45 to 0.84 (P < 0.01).</p><p><b>CONCLUSION</b>The reliability and validity of the parent proxy-report scales of PedsQL 4.0 Generic Core Scales of the Chinese Version were as good as the original version. Our findings suggested that the scales could be applied to evaluate the health-related quality of life in childhood children in similar Chinese regions to Guangzhou.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the effects of dietary fatty acids on the serum lipids in hypercholesterolemic subjects.</p><p><b>METHODS</b>All 297 residents with hypercholesterolemia were enrolled in Guangzhou. The dietary composition and the changes in serum lipid levels during the 6-month follow-up were analyzed.</p><p><b>RESULTS</b>(1) 297 subjects were enrolled and 281 subjects (88 male, 193 female) completed the 6-month follow-up. The serum TC concentration of the subjects was (6.09+/-0.68) mmol/L at baseline. (2) According to the percentage of energy from total fat, all of the subjects were divided into three groups, including total fat % en<25% (group I, 90 subjects), 25%-30% (group II, 97 subjects), >30% (group III, 94 subjects). The reduction of TC and LDL-C in group I and group II was greater than that in group III. (3) According to the percentage of energy from SFA, all of the subjects were divided into three groups, including SFA % en<7% (group I, 81 subjects), 7%-10% (group II, 129 subjects), >10% (group III, 71 subjects). The reduction of TC and LDL-C in group I and group II was greater than that in group III. (4) All of the subjects were divided into three groups, according to the percentage of energy from MUFA, including MUFA % en<10% (group I, 93 subjects), 10%-13% (group II, 106 subjects), >13% (group III, 82 subjects). The reduction of TC and LDL-C in group II was greater than that in group I and group III. (5) All of the subjects were divided into three groups according to the percentage of energy from PUFA, including PUFA % en<7% (88 subjects), 7%-9% (94 subjects), >9% (99 subjects).

ABSTRACT

<p><b>OBJECTIVE</b>To assess the association of physical activity with bone mass in premenarche girls.</p><p><b>METHODS</b>Bone mineral density (BMD) and bone mineral content (BMC) at the whole body, femoral neck, Ward triangle and L1-L4 spine were measured using dual-energy X-ray absorptiometry (DXA) in 194 premenarche girls (10 +/- 1, year). Physical activity and dietary calcium intakes were assessed by using frequency questionnaire and diary.</p><p><b>RESULTS</b>It was found that BMD and BMC were significantly and positively associated with weight-bearing physical activities (WBPA) (P < 0.01), total physical activities (TPA) (P < 0.01) rather than non-weight-bearing physical activity (P > 0.05) at all the studied bone sites (P < 0.01). Both BMC and BMD were tending to a better increase of WBPA. When WBPA increases from 227 to 415 (kcal/d), mean BMC and BMD were increased in 17.5%-29.0% and 8.8%-17.1%, respectively.</p><p><b>CONCLUSION</b>It should be helpful for premenarche girls to improve bone mass by increasing physical activities, especially weight-bearing physical activities.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the prevalence rate of hypertension and the risk factors in Guangxi Hei Yi Zhuang population.</p><p><b>METHODS</b>A total of 1068 people of Hei Yi Zhuang nationality aged 20 and over were surveyed. Blood pressure, height, weight, serum lipid and apolipoprotein levels were measured ,and both body surface areas and body mass index were calculated. Results were compared with those in 933 people of Han nationality living in the same district.</p><p><b>RESULTS</b>The prevalence rates of hypertension in Hei Yi Zhuang population were significantly higher than that in Han population (25.2% vs. 17.3%, P < 0.001) ,as well as the isolated systolic hypertension (12.5% vs. 3.9%, P < 0.001). The mean levels of systolic pressure and pulse pressure in Hei Yi Zhuang population were significantly higher than those in Han population (125.20 +/- 18.62 vs. 121.88 +/- 15.99 mm Hg, P < 0.001 and 48.64 +/- 14.75 vs. 44.98 +/- 11.12 mm Hg, P <.001; respectively). The prevalence rate of hypertension in Hei Yi Zhuang population was positively correlated with triglyceride, sex and age whereas the prevalence rate of hypertension in Han population was positively correlated with total cholesterol, sex, age, and alcohol consumption. Rates of awareness on hypertension in Hei Yi Zhuang and Han population were 8.6% vs. 21.1% (P <.001), patients with treatment rate of established hypertension were 4.5 vs. 15.5 (P < 0.001) with the control rates as 1.9 vs. 10.6 (P < 0.001).</p><p><b>CONCLUSION</b>The prevalence rate of hypertension in Guangxi Hei Yi Zhuang population was significantly higher than that in Han ethnic group. The causes of high prevalence rate of hypertension might be ascribed to special geographical surroundings, unhealthy life style, high sodium intake, low education, and possibly genetic factors. The rates on awareness, treatment and control of hypertension were still under satisfaction.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effect of a novel blockade technique for gastric cancer on blood-borne metastasis of gastric cancer cells to portal vein.</p><p><b>METHODS</b>Twenty-three cases of gastric cancer were divided into routine operation group (8 cases intraoperatively without blockade technique) and blockade group (15 cases with blockade technique). Blood samples from portal vein pre- and intraoperatively, as well as gastroepiploic vein limited within the blockade area were obtained to detect CK19 mRNA expression by using RT-PCR technique.</p><p><b>RESULTS</b>Before the dissection of gastric lesion, the overall positive rate of CK19 mRNA expression in portal vein blood is 34.7% (9/23), including 37.5% (3/8) in routine operation group and 33.3% (5/15) in blockade group. While the course of tumor resection, those positive rates were 87.5% (7/8) in routine operation group and 6.7% (1/15) in blockade group respectively (P < 0.05). CK19 mRNA expression in the right gastroepiploic venous blood limited within the blocking area was all positive in 15 cases of blockade group.</p><p><b>CONCLUSION</b>This blockade technique can be used effectively to block the intraoperative spread of gastric cancer cells, thus prevent blood-borne metastasis due to operative manipulation.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the validity of criteria currently used in China for the classification of symmetric small for gestational age infants (SGA) as compared with its definition.</p><p><b>METHODS</b>This study included 417 inpatients diagnosed as SGA in authors' hospital from January 1998 to June 2002. Symmetric SGA was diagnosed by the following three criteria: (1) the Ponderal Index (PI), (2) the crown-heel length-to-head circumference ratio (BL/HC) issued in Chin J Pediatr (1988;26:164 - 165), as well as (3) the SGA definition. The definition criterion was considered as the "gold standard". The sensitivity, specificity, false positive and negative values, positive and negative predictive values, exact agreement ratio, diagnosis index, and Cohen's Kappa value were used to evaluate the validity and agreement of the methods of PI and BL/HC. Receiver Operating Characteristic (ROC) analysis was used to evaluate the validity of the diagnosis.</p><p><b>RESULTS</b>Of 417 SGA infants, 376 (90.17%), 376 (90.17%) and 187 (44.84%) subjects were diagnosed as symmetric type with PI, BL/HC and the definition criteria, respectively. (2) The agreement rate and Kappa value between PI and BL/HC was 80.82% and -0.093 (SEM 0.026), respectively. And the agreement rates between PI or BL/HC and the definition criterion were 49.88% and 50.84%, respectively. As compared with the definition criterion, the PI and BL/HC methods had sensitivities of 91.8% - 96.4%, specificities of 9.3% - 25.9%, positive predictive values of 45.8% - 51.1%, negative predictive values of 72.7% - 82.8%, diagnosis indices of 4.9% - 17.7% and Kappa values of 0.070 - 0.167. (3) The areas under the ROC curves in full-term and preterm infants by PI method were 0.635 (95% CI, 0.573 - 0.697) and 0.698 (95% CI, 0.622 - 0.725), respectively. PI cutoffs at 2.47 in full-term SGA, at 2.43 in preterm SGA, and BL/HC cutoff at 1.43 produced the maximum diagnosis indices that were 24.7%, 39.6% and 33.7%, respectively. When the PI at 2.50 (full-term), PI at 2.31 (preterm) and BL/HC values at 1.46, the sensitivity closed mostly to the specificity. The sensitivities and specificities in full-term and preterm infants were 59.4% and 59.3%, 65.3% and 65.5%, and 66.3% and 65.5%, respectively.</p><p><b>CONCLUSION</b>In the classification of SGA, the results showed a poor agreement between PI or BL/HC and the definition criterion. The results suggested that the current cutoffs of PI and BL/HC might not be appropriate for the diagnosis of symmetric SGA. Low AUC suggested that PI and BL/HC could not give a valid diagnosis at any cutoffs.</p>
