ABSTRACT
Objective:Long-term proton pump inhibitor(PPI) therapy may increase the risk of small intestinal bacterial overgrowth(SIBO). Few studies on the effect of on-demand and continuous PPI therapy are available in elderly. To investigate the prevalence of SIBO and the effect of on-demand and continuous PPI therapy on SIBO in elderly.Methods:A total of 200 elderly outpatients admitted to Department of Gastroenterology at the Second Medical Center of PLA General Hospital were enrolled and divided into 3 groups: continuous PPI group, on-demand PPI group and control group. SIBO was diagnosed according to methane and hydrogen lactulose breath test (LBT).The prevalence of SIBO in the 3 groups was analyzed.Results:The prevalence of SIBO was 71.5% in 200 elderly. PPI therapy and diabetes mellitus (DM) were independent risk factors for SIBO. The prevalence of SIBO was 77.1% (108/140) in elderly who underwent long-term PPI therapy and 58.3% (35/60) in those without PPI therapy ( P<0.01).The prevalence of SIBO was significantly higher in continuous PPI therapy group than that in on-demand PPI group and control group(88.6% vs. 65.7% and 58.3%, all P<0.01).However, no significant difference was found in the prevalence of SIBO between on-demand PPI group and control group ( P>0.05). In elderly who underwent long-term PPI therapy, the prevalence of SIBO increased significantly if administration time was longer than 61 months. Conclusions:SIBO usually occurs in elderly patients who receive continuous PPI rather than on-demand use. If elderly require long-term PPI therapy, on demand administration is suggested as long as primary diseases are properly treated.

ABSTRACT
Objective To study the occurrence of bronchopulmonary dysplasia (BPD) in extremely low birth weight (ELBW) infants and to determine the risk factors of severe BPD.Method From January 2007 to January 2017,ELBW infants admitted to neonatal intensive care unit (NICU) in Hunan Children's Hospital were retrospectively analyzed.They were assigned into severe and mild/moderate groups based on the severity of BPD.The general condition,maternal status,prenatal and delivery room treatment,transportation,clinical courses,therapy and outcome in NICU of the two groups were compared,and the risk factors of severe BPD were analyzed.Result A total of 367 cases were hospitalized during the 10 years.281 ELBW infants with complete medical records survived longer than 28 days were enrolled in this study.Among them,233 had BPD.Among BPD infants,116 cases were in the severe BPD group,47 cases (40.5％) died.117 cases were in the mild/moderate BPD group and 1 case (0.9％) died.The difference between the two groups was statistically significant (P ＜ 0.05).Multivariate Logistic regression analysis showed that the risk factors of severe BPD were duration of mechanical ventilation ≥ 7 days (OR =7.518,95 ％ CI 3.197 ～ 17.676),ventilator-associated pneumonia (OR =3.047,95 ％ CI 1.436 ～ 6.464),1 min Apgar score ≤7 (OR =2.341,95 ％ CI 1.142 ～ 4.796) and patent ductus arteriosus (OR =2.223,95 ％ CI 1.079 ～4.582).Conclusion The incidence and mortality of BPD,especially severe BPD,are high in ELBW infants.Avoiding asphyxia,shortening the time of mechanical ventilation,preventing infection and closing ductus arteriosus are important measures to reduce the severity of BPD.
ABSTRACT
Objective To study the transport risk and factors that influence deaths of very low birth weight (VLBW) and extremely low birth weight (ELBW) infants.Method All infants transferred to our neonatal intensive care unit (NICU) by our hospital transport team or local hospital transport team from January 2014 to December 2015 were included in our study.Their clinical data were retrospectively studied.The risks of transport between hospitals were analyzed.The risk factors of deaths within and after 7 days of admission were further analyzed by multivariate Logistic regression analysis.The receiver operation characteristic (ROC) curve was used to assess the sensitivity and specificity of mortality index for neonatal transportation (MINT),transport related mortality score (TREMS),transport risk index of physiologic stability (TRIPS) for predicting mortality of preterm infants.Result (1) A total of 527 cases of ELBW/VLBW infants were included in our study.There were no deaths during transport.There were 10.2％ (54/527) died within and 8.9％ (42/473) died after 7 days of hospitalization.(2) Multivariate Logistic regression analysis showed that scleredema of newborn,secondary transport,gastrointestinal malformations,metabolic acidosis,high TREMS score,and high MINT score were risk factors of mortality within 7 days of admission for ELBW/VLBW infants;necrotizing enterocolitis,intraventricular hemorrhage ≥ three degree,high MINT score and low admission weight were risk factors of mortality after 7 days of admission.(3) The area under the ROC curve for MINT,TREMS,and TRIPS score were 0.672,0.655 and 0.665,respectively.The cut-off values for MINT score (cut-off 8,sensitivity 0.444,specificity 0.829),for TREMS score (cut-off 2,sensitivity 0.500,specificity 0.757,for TRIPS score (cut-off 20,sensitivity 0.444,specificity O.829) were selected to predict mortality within 7 days of admission.Conclusion (1) Secondary transport is the transport-related risk factor of mortality within 7 days of admission for ELBW/VLBW infants.(2) High MINT score is the risk factor of mortality within and after 7 days of admission.(3) If MINT ≥ 8,TREMS ≥2,or TRIPS ≥20,it might significantly increase the risk of mortality of ELBW/ VLBW infants within 7 days of admission after transport.
ABSTRACT
Objective To realize the clinical characteristics of fungemia in premature infants.Methods Clinical characteristics of fungemia in premature infants in the intensive care unit of a children''s hospital between January 2011 and December 2015 were analyzed retrospectively, general condition of premature infants, laboratory-related indicators, and antimicrobial susceptibility testing results were compared.Results From January 2011 to December 2015, 42 premature infants with confirmed fungemia were treated in this hospital, 22 (52.38％) of whom were with fungemia caused by Candida albicans(C.albicans), 13 (30.95％) by Candida parapsilosis (C.parapsilosis), 3 by Candida krusei (C.krusei), and 4 by other fungi.Patients were grouped according to the main pathogens causing infection: C.parapsilosis group and C.albicans group.Maternal genitourinary tract infection rate and incidence of fungal meningitis in C.albicans group were both higher than C.parapsilosis group(27.27％ vs 7.69％, 27.27％ vs 0.00％ respectively), peripherally inserted central catheter (PICC) rate in C.albicans group was lower than that in C.parapsilosis group(22.73％ vs 69.23％), platelet count in C.parapsilosis group was lower than C.albicans group, differences were all statistically significant (all P<0.05).Conclusion The major fungi causing fungemia in premature infants were C.parapsilosis and C.albicans, maternal reproductive system infection during pregnancy can easily lead to candidemia, premature infants with candidemia are more vulnerable to developing fungal meningitis;PICC is more likely to lead to C.parapsilosis fungemia, and platelet decline is more obvious.
ABSTRACT
Objective To explore the application of high frequency oscillation in the area of respiratory distress syndrome (RDS) of premature.Methods A total of 101 cases with RDS of premature was collected who needed the machine support in neonatal intensive care unite (NICU) during 2010.11.01-2011.10.30.Forty one cases (high frequency oscillation group) received the high frequency oscillation,while 60 cases received the common ventilation (Control Mechanical Ventilation group;control group).The results of blood gas analysis were recorded before ventilation,after ventilation for 2 hours,after ventilation for 12 hours,and after ventilation for 24 hours.The chest X-Ray and the complication were examined.Results The result of the blood-gas before ventilation,after ventilation for 2 hours,after ventilation for 12 hours,and after ventilation for 24 hours,FIO2,PO2,PCO2,and Pa(A-a) were statistically analyzed,and F-value was 16.202,14.764,16.135,8.434,P ＜ 0.01.For chest X-ray in high frequent oscillation group,there were 36 cases who had improved after ventilation 24 hours and all had improved after ventilation 72 hours;however,in common ventilation group,there were 30 cases who had improved after 24 hours and 50 cases had improved after 72 hours,x2 =15.372 and 7.584,P ＜ 0.01,there was statistical difference for two groups.However,there were not different in cerebral injury/healing damage and retinopathy of prematurity (ROP) for two groups.Conclusions High frequency oscillation is an effective way to treat RDS of premature.
ABSTRACT
Objective To investigate the effect of illness severity on preterm infant's hypothalamusputituary-adrenal (HPA) axis, we measured the serum concentration of cortisol,aldosterone and adrenocorticotropic hormone (ACTH). Methods Ninety preterm infants who were transferred to our hospital within 72 hours after birth were involved. These preterm infants were divided into two groups:gestational age (GA) ≥34 weeks' preterm infants and GA <34 weeks' preterm infants. We evaluated these preterm infants at the time of admission,day 7 and day 14 after birth with neonatal critical illness score (NCIS). Then they were divided into mild group and severe group by the lowest score. We measured their serum cortisol,aldosterone and ACTH at the time of admission,day 7 and day l4 after birth. Results (1) The serum cortisol concentration of preterm infants with severe illness was higher than that of preterm infants with mild illness. Among the GA ≥34 weeks' preterm infants,the serum cortisol concentration of preterm infants with severe illness was significandy higher than that of preterm infants with mild illness within 72 hours after birth (t = -2.263,P =0. 029). Among the GA <34 weeks' preterm infants,the serum cortisol concentration of preterm infants with severe illness was significantly higher than that of preterm infants with mild illness on day 14 after birth (t =-2. 913 ,P =0. 006). (2) Among the preterm infants with severe illness,the serum cortisol concentration of the GA≥34 weeks' was significantly higher than that of the GA < 34 weeks' within 72 hours after birth (t =-2. 641 ,P =0. 010) ;the serum cortisol concentration of the GA <34 weeks' was significantly higher than that of the GA≥34 weeks' on the day 14 after birth(t = -2. 189,P =0. 036) . (3) The serum cortisol concentration was significantly decreased in the GA≥34 weeks'preterm infants (F = 4. 679, P =0. 012). (4) The serum cortisol concentration of aldosterone and ACTH was not significantly different between preterm infants with severe illness and those with mild illness. Conclusion The preterm infant already has the ability to respond to stimuli by regulating cortisol secretion. The serum cortisol concentration increases as disease severity worsens.Serum aldosterone and ACTH concentration are not correlated with the severity of the disease.
