Law From a law review The lower birth weight literature review implications of this ruling for international law are well documented, since they have been shown to facilitate the growth of bifidobacteria and lactobacilli in the colon of breast-fed neonates [ 36 – 38 ]. Quantification of caffeine intake Caffeine intake was estimated with a validated caffeine assessment tool, a questionnaire designed at the University of Leeds, to record habitual caffeine intake before and during pregnancy.
We recorded specific brand names, portion low birth weight literature review, methods of preparation, and quantity and frequency of intake for different gestational periods. We also obtained details Essay about friendship 50 words caffeine content for each item from published reports, 27 manufacturers, and coffee houses, and, from these, we estimated precise caffeine intakes using an SPSSv14 program low birth weight literature review in-house.
Saliva sample collection, storage, and transport Saliva samples for determining nicotine exposure defined as baseline values before the caffeine challenge were collected from women at recruitment, using a Salivette Sarstedt, Aktiengesellschaft, Loughborough, UK kept in the mouth for minutes.
Additionally, we assessed caffeine half life from a caffeine challenge test adapted from Butler et al 28 performed within two weeks of recruitment. We provided participants with appropriate materials and instructions to perform the test at home, and the samples were then returned in a prepaid envelope.
The test involved low birth weight literature review fasting, followed by the challenge a drink of ml diet cola containing Participants then collected saliva samples about one and five hours after the challenge.
Precise sample collection times and details of drinks or food consumed during the test period were recorded on a questionnaire. Salivary caffeine—Salivary caffeine was extracted and quantified using liquid: In addition, we assessed the association of maternal caffeine intake with birth weight.
We performed unconditional logistic regression modelling for fetal growth restriction and general linear modelling for birth weight, with stratification for the two homework weekly planner units, using Stata version 10 survey facilities. We also made statistical adjustment for salivary cotinine levels and self reported alcohol consumption in all models.
We conducted sensitivity analyses to assess the robustness of the results to adjustment for nausea, exclusion of low birth weight literature review risk pregnancies, multiparity, low birth weight literature review high or low caffeine intakes, and the maternity unit.
We also assessed the relation between the risk of fetal growth restriction and maternal caffeine intake during pregnancy by considering caffeine intake as a continuous variable: Caffeine half low birth weight literature review as assessed by the caffeine challenge test was not normally distributed.
The study found that preterm infants who received the supplement containing several species of lactobacilli and bifidobacteria plus fructooligosaccharides were more likely to become colonized with bifidobacteria. There were no significant differences in weight gain or the content of short-chain low birth weight literature review acids in the stool between groups. Antenatal Steroids Crowley reviewed the literature to assess the effects on fetal and neonatal morbidity and mortality and showed that treatment with antenatal corticosteroids is associated with a reduction in the incidence of RDS and IVH and a trend towards reduction in the incidence of NEC [ 45 ].
Possible explanations for the increase in NEC include the increased survival of more immature infants, increased use of antenatal steroids, and perhaps a tendency to institute and Thesis open access prudent, given the improved pulmonary status of these neonates.
Cochrane review which included 3 studies concluded that restricted water intake significantly reduces the risks of morbidities low birth weight literature review NEC [ 47 ].
Prophylactic Enteral Antibiotics The administration of prophylactic oral antibiotics has been investigated in NEC prevention. Evidence to date indicates that oral antibiotics can reduce NEC incidence [ 4849 ].
A statistically significant increase in the incidence of colonization with resistant bacteria was also shown. Thus routine use of prophylactic antibiotics cannot be recommended [ 50 ]. Lactoferrin Supplementation Lactoferrin, an antimicrobial glycoprotein present in colostrum and breast milk, is a key component of the mammalian innate response to infection.
Lactoferrin has broad microbicidal activity against Gram-positive cocci, Gram-negative bacilli, and Candida species. VLBW infants have low lactoferrin levels and this deficiency is exacerbated by delay in establishing enteral feeding.
A recently published Italian multicentre trial examined whether enteral supplementation with exogenous bovine lactoferrin for up to 6 weeks, either alone or in combination with a probiotic Lactobacillus, reduced the risk of NEC and low birth weight literature review nosocomial infection in VLBW infants. The incidence of NEC was decreased in the lactoferrin plus probiotic group only. It is plausible that a more modest independent effect of lactoferrin on the risk of NEC may still exist and further large trials are proposed to investigate this possibility.
Oral Immunoglobulins Immunoglobulins are one of many low birth weight literature review factors in human milk responsible for its protective effects on NEC. Neonates have decreased immunoglobulin levels, particularly secretory IgA [ 51 ]. Further trials are needed. In animal models of experimental enterocolitis, glutamine supplementation reduces mucosal damage and lowers the risk of invasive infection and death. Glutamine is abundant in human milk but present only in much lower levels in cow milk formula and absent in standard parenteral nutrition solutions.
A relative deficiency of arginine leading to inadequate NO production might predispose the premature infant to inadequate tissue NO levels, vasoconstriction, ischemic-reperfusion injury, and ultimately the development of proofreading editing services as a risk factor for the development of NEC [ 54 ].
Furthermore, meta-analyses of good low birth weight literature review randomized controlled trials of nonsteroidal anti-inflammatory agents for patent ductus arteriosus closures have not detected any significant effects dishtvchannels.000webhostapp.com the incidence of NEC. Polyunsaturated Fatty Acids Supplements Long chain fatty acids have been proposed to modulate inflammation and immunity.
Recently Carlson has shown low birth weight literature review incidence of NEC in group supplemented with egg phospholipids [ 56 ]. Acidification of Gastric Contents Carrion and Egan have documented that acidifying the feedings of preterm neonates to a pH low enough to inhibit gastric bacterial proliferation significantly lowers the risk of NEC [ 57 ].
Evidence exists that the use of histamine-receptor type 2 H2 blockers to suppress gastric acidity is associated with a higher risk of NEC and nosocomial infection in VLBW infants. Given lack of evidence that gastrooesophageal reflux is a cause of apnoea in preterm infants, it is recommended that use of H2 blockers should be restricted until robust i always do my homework in spanish that benefits outweigh harmful effects is obtained.
The indications for surgery include presence of pneumoperitoneum, indicating perforation of the low birth weight literature review, clinical deterioration despite maximal medical treatment, abdominal mass with intestinal obstruction, and development of intestinal stricture.
Relative indications include low birth weight literature review dilated intestinal loop, presence of portal gas, thrombocytopenia, and rapid fall in platelet count [ 60 ]. Conclusion NEC continues to be one of the most devastating and unpredictable diseases affecting premature infants. Although no difference was observed in the treatment failure rate between caffeine citrate and theophylline 23caffeine citrate is superior to theophylline for apnea of prematurity because of the once daily dose, lack of need of monitoring the drug low birth weight literature review, early onset of the effect, and minimal side effects 23456.
The use of doxapram could be harmful in the developing brain, with the possibility of cerebral dysfunction 7.
Only one study 14 mentioned the dosage of caffeine in a previous report, the CAP trial 5. Caffeine has the effect of reducing the frequency of apnea and improving low birth weight literature review function because, as a bronchodilator, it reduces diaphragmatic fatigue, it increases respiratory muscle strength, and it reduces resistance and increases compliance 221222324 Recently, the low birth weight literature review effects of caffeine in preterm infants, low birth weight literature review in the long-term and short-term, have been reported.
In addition, its effects on respiratory function, including apnea 5610 and the efficacy of the early commencement of caffeine therapy 141720have also been reported. The beneficial effect of caffeine on other neonatal morbidities may result from the anti-inflammatory and immunomodulatory properties of caffeine 2627 and the check my essay of caffeine during a critical period of disease progression or organ development in preterm infants The use of caffeine in preterm infants could affect neonatal outcomes by reducing the frequency of apnea and intermittent hypoxia, which can activate the pro-inflammatory cascade 111228 and the anti-inflammatory action of caffeine itself 1112 In the CAP trial 6the death rates did not differ between the caffeine group and the non-caffeine group, but early caffeine use was associated with a reduced risk of death compared to late caffeine use in this meta-analysis OR, 0.
The proposed low birth weight literature review mechanism of caffeine of reducing the risk of BPD is the blockade of the adenosine 2 receptor, which acts on inflammation and increases permeability and remodeling in the lung how to write autobiography essay for scholarship cerebral blood flow in IVH 910 Because it is the low birth weight literature review of greatest vulnerability to brain injury, the protective effect of caffeine may only manifest in the early caffeine group 9 As shown by the results of this meta-analysis, early caffeine use was associated with a decreased risk of ROP requiring laser photocoagulation OR, 0.
The use of caffeine was not low birth weight literature review with a difference in the incidence of NEC compared to the non-caffeine group 531but there was no information on the time of initiation of caffeine therapy.
The early initiation of caffeine did not reduce the risk of NEC 2 and was not low birth weight literature review with an increased risk of NEC Methylxanthine prophylaxis increased the success of extubation compared to the placebo group in preterm infants 32and the mean duration of mechanical ventilation was shorter in the early caffeine group than in the late caffeine group However, the results of the meta-analysis found no significant difference in the duration of mechanical ventilation between the early and late caffeine groups standard mean difference, The day of caffeine initiation mean value was 0.
In the study by Taha et al. dissertation on call centers
Therefore, the duration of mechanical ventilation was shortened with early caffeine therapy standard mean difference, Four studies 14151617 mentioned the duration of low birth weight literature review ventilation and were low birth weight literature review in the meta-analysis on the duration of mechanical ventilation, and two studies 1417 were excluded because they described the post-menstrual age at the last positive pressure ventilation or only mentioned the median value of mechanical ventilation.
Only two studies were included in this meta-analysis on the duration of mechanical ventilation, and inconsistent results were shown between the random and fixed effect model. Therefore, further studies are buy narrative essay to assess the effect of caffeine on the duration of low birth weight literature review ventilation.
The side effects following caffeine use did not differ compared to the placebo group, except for a temporary weight reduction 533 that was postulated to be an effect of the diuretic effect of caffeine Therefore, Caffeine use was found to have short-term and long-term benefits in preterm infants 56.
Some limitations of the present study need to be addressed. First, only one RCT study 8 regarding the effects of the early administration of caffeine was included, and we used a retrospective study in the meta-analysis. Second, we could not report the effect of early caffeine use on the treatment of apnea.
