Abstract BACKGROUND Host immunity is essential for efficient recognition and clearance of M. tuberculosis infection. Polymorphisms in genes that regulate immune response have been reported to influence the susceptibility/resistance to pulmonary tuberculosis (TB). Here we evaluated associations between 14 polymorphisms in 12 core genes involved in immune responses and pulmonary TB in Moldavian population, and investigated whether interactions between these and previously analyzed polymorphisms could exist and modulate the risk of pulmonary TB. METHODS Polymorphisms VDR rs7975232, VDR rs1544410, VDR rs2228570, MR1 rs1052632, TLR1 rs5743618, TLR2 rs111200466, TLR10 rs11096957, SLC11A1 rs2276631, IL1B rs1143643, IL10 rs1800896, IFNG rs2430561, TNF rs1800629, IRAK1 rs1059703, and FOXP3 rs2232365 were genotyped in 271 Moldavian pulmonary TB cases and 251 community-matched healthy controls. Associations were tested using Fisher test and logistic regression. Complemented with the data from our previous study (PMID: 30529560), investigation of gene-gene interactions was performed for a total of 43 loci. Significance level was adjusted by the Bonferroni correction. RESULTS Single polymorphism analysis revealed a nominal association between TNF rs1800629 and pulmonary TB (Fisher exact test p-value = 0.01843). Marginal differences between cases and controls were observed for haplotypes in the gene cluster TLR1-TLR6-TLR10 and gene TLR2. In the pairwise interaction analysis, the combination of genotypes TLR6 rs5743810 GA and TLR10 rs11096957 GT was significantly associated with an increased genetic risk of pulmonary TB (OR = 2.48, 95% CI = 1.62–3.85; Fisher exact test p-value = 1.5 × 10− 5, significant after Bonferroni correction). CONCLUSION The TLR6 rs5743810 and TLR10 rs11096957 two-locus interaction confers a significantly higher risk for pulmonary TB and has potential as a novel biomarker for predicting TB susceptibility.

Polymorphisms in genes that control immune function and regulation may influence susceptibility to pulmonary tuberculosis (TB). In this study, 14 polymorphisms in 12 key genes involved in the immune response ( VDR, MR1, TLR1, TLR2, TLR10, SLC11A1, IL1B, IL10, IFNG, TNF, IRAK1, and FOXP3) were tested for their association with pulmonary TB in 271 patients with TB and 251 community-matched controls from the Republic of Moldova. In addition, gene–gene interactions involved in TB susceptibility were analyzed for a total of 43 genetic loci. Single nucleotide polymorphism (SNP) analysis revealed a nominal association between TNF rs1800629 and pulmonary TB (Fisher exact test P = 0.01843). In the pairwise interaction analysis, the combination of the genotypes TLR6 rs5743810 GA and TLR10 rs11096957 GT was significantly associated with an increased genetic risk of pulmonary TB (OR = 2.48, 95% CI = 1.62–3.85; Fisher exact test P value = 1.5 × 10−5, significant after Bonferroni correction). In conclusion, the TLR6 rs5743810 and TLR10 rs11096957 two-locus interaction confers a significantly higher risk for pulmonary TB; due to its high frequency in the population, this SNP combination may serve as a novel biomarker for predicting TB susceptibility.

Tuberculosis (TB) is considered as the leading killer among infectious diseases because of bacteria resulted in a high number ofmorbidity and mortality world wide. One risk factor for tuberculosisis diabetes mellitus (DM). The prevalence of TB and DM jump together globally, especially in developing countries, including Indonesia. Early and accurate diagnosis of TB cases in the enforcement is sputum smear examination. Monitoring of TB seen through sputum conversion. The purpose of this studyis to determine the duration of sputum conversion difference new case smear positive pulmonary TB patients with and without DM in hospital Prof. Dr.Margono Soekarjo (RSMS) Purwokerto. Thestudy design is observational analytic with cohort retrospective study. Sample of this study was patients who checked their health in Lung Clinis of RSMS Purwokerto obtained total sample of 44 people, consisting of 22 patients clinically diagnosed new cases smear-positive pulmonary TB with DM and 22 patients without DM in 2009 until 2012.Results of this study were analyzed using Fisher Exact Test. pvalues obtainedof 0.000 (p <0.05) (95% CI = 0,288-0,718) with relative risk 0,455. The conclusion is there were significant differences in sputum conversion time between the group of patients suffering from pulmonary uberculosis with and without DM. The conversion of sputum in patients with pulmonary tuberculosis who suffered DM is longer than patients without DM. Relative risk value which is equal to 0.455 which means that patients with DM have pulmonary tuberculosis risk by 0.455 times more likely to experience delays in sputum conversion than TB patients without DM

Abstract OBJECTIVE To identify the presence of phlebitis and the factors that influence the development of this complication in adult patients admitted to hospital in the western Brazilian Amazon. METHOD Exploratory study with a sample of 122 peripheral intravenous catheters inserted in 122 patients in a medical unit. Variables related to the patient and intravenous therapy were analyzed. For the analysis, we used chi-square tests of Pearson and Fisher exact test, with 5% significance level. RESULTS Complication was the main reason for catheter removal (67.2%), phlebitis was the most frequent complication (31.1%). The mean duration of intravenous therapy use was 8.81 days in continuous and intermittent infusion (61.5%), in 20G catheter (39.3%), inserted in the dorsal hand vein arc (36.9 %), with mean time of usage of 68.4 hours. The type of infusion (p=0.044) and the presence of chronic disease (p=0.005) and infection (p=0.007) affected the development of phlebitis. CONCLUSION There was a high frequency of phlebitis in the sample, being influenced by concomitant use of continuous and intermittent infusion of drugs and solutions, and more frequent in patients with chronic diseases and infection.

Background/aimDiastasis recti abdominis (DRA) is defined as a separation of the 2 muscle bellies of rectus abdominis. To date there is scant knowledge on prevalence, risk factors, and consequences of the condition. The present study aimed to investigate the prevalence of DRA during pregnancy and post partum, presence of possible risk factors, and the occurrence of lumbopelvic pain among women with and without DRA.MethodsThis prospective cohort study followed 300 first-time pregnant women from pregnancy till 12 months post partum. Data were collected by electronic questionnaire and clinical examinations. DRA was defined as a palpated separation of ≥2 fingerbreadths either 4.5 cm above, at or 4.5 cm below the umbilicus. Women with and without DRA were compared with independent samples Student's t-test and χ2/Fisher exact test, and OR with significance level >0.05.ResultsPrevalence of DRA was 33.1%, 60.0%, 45.4%, and 32.6% at gestation week 21, 6 weeks, 6 months and 12 months post partum, respectively. No difference in risk factors was found when comparing women with and without DRA. OR showed a greater likelihood for DRA among women reporting heavy lifting ≥20 times weekly (OR 2.18 95% CI 1.05 to 4.52). There was no difference in reported lumbopelvic pain (p=0.10) in women with and without DRA.ConclusionsPrevalence of mild DRA was high both during pregnancy and after childbirth. Women with and without DRA reported the same amount of lumbopelvic pain 12 months post partum.

Objectives: To identify if the presence of migraine before pregnancy predisposes to hypertensive disorders of pregnancy. Methods: Observational study undertaken from a database of a follow-up study, composed of women consecutively assisted, at the first postnatal week, at IMIP. Its objective was to evaluate the course of migraine during pregnancy and postpartum in women with migraine before pregnancy. The Fisher exact test was used considering the significance level of less than 5%. Results: Of the 686 women, 38.8% were migraine sufferers before pregnancy. 14.3% referred hypertensive disorders of pregnancy. The presence of migraine before pregnancy and to have been submitted to a cesarean section (p<0.001) were factors associated with the presence of hypertensive disorders in pregnancy. Conclusion: Migraine before pregnancy is an associated factor to hypertensive disorders of pregnancy. The diagnosis of migraine should always be taken into consideration during antenatal care, for the prevention of complications.

Introduction: Uterine prolapse is a gynecological problem that women often experience with a prevalence of 50% and is predicted that the next 30 years will increase by 45% as life expectancy increases. Increased degrees of uterine prolapse have an impact on the deterioration of women's quality of life. The uterine prolapse is influenced by several mutually supportive factors. The purpose of this study was to analyze the relationship between these factors to the degree of uterine prolapse.Methods: This research is an observational analytic research with cross sectional approach. The number of samples were 65 patients with uterine prolapse at Policlinic Gynecology RSUD Dr. Soetomo Surabaya from 2015-2017. Sampling was done by consecutive sampling. To find out the significant level, the collected data will be tested with Fisher Exact Test statistic at significance level α = 0,05.Results: The result showed that there was significant difference between degree of uterine prolapse with age factor (p = 0,016) and obesity (p = 0,041). As for the parity factor (p = 0.508) there was no significant difference between the parity factor and the degree of uterine prolapse.Discussion: Age is a major factor affecting the degree of uterine prolapse, weakening of pelvic floor tissue and muscle in elderly women is the main cause. While on the obesity factor, there is no data to support that obesity is related to the degree of uterine prolapse because the trend indicates that the majority of patients are not obese. In contrast the parity factor, although according to the statistical test there is no difference to the degree of uterine prolapse, the trend shows that parity leads to increased incidence of uterine prolapse itself.Conclusion: Age is a factor that affects the degree of uterine prolapse.

Introduction: Hyperuricemia (HU) is the strongest predictor of gout and highly associated with major CVD including hypertension, HF, and CKD. The Hmong, a unique Asian population numbering > 60,000 in Minnesota, have a two-fold increased risk of gout compared to non-Hmong, rising prevalence of CVD, and may differ from other Asian populations in these regards. A genetic predisposition to elevated Serum Uric Acid (SUA) may help identify individuals at risk for gout and CVD. We quantified the Minor Allele Frequencies (MAFs) of known genetic variants (SNPs) associated with HU and compared the MAFs between our Hmong sample and both a reference (HapMap) population of Caucasian (CEU) as well as Han-Chinese (CHB). Methods: Salivary DNA from 235 self-identified Hmong was genotyped using either a Sequenom (iPLEX Gold) or TaqMan approach. MAFs for seven SNPs within candidate genes ( SLC2A9, SLC22A12, PDZK1, and ABCG2 ) identified by GWAS, were determined in our Hmong sample. Associations between HU and genotype were examined for 57/235 Hmong with known SUA levels. A Chi-Square or Fisher exact test with a Bonferroni corrected significance level (<0.007) was used to evaluate MAF differences. Mean SUA concentrations were compared by genotype using one-way ANOVA. Results: Our Hmong participant's age [mean (±SD)] was 30.2 (15.4) years, with >61% overweight or obese and a mean (±SD) SUA of 6.3 (1.7) mg/dL. Although the frequency of risk alleles in the Hmong were significantly higher compared to CEU (6/7) and CHB (3/7) populations, independent SNP by SNP analysis did not show a clear association with SUA. Risk allele frequencies were always more frequent in the Hmong versus comparator groups. Conclusion: MAFs of selected SNPs for HU are not independent of race. The higher prevalence of risk alleles for HU in the Hmong versus CEU and CHB populations may partly explain the clinically observed higher prevalence of gout and CVD risk in the Hmong. Although sample size precludes a robust assessment of an association between genotype and SUA, to our knowledge this is the first study to examine the genetic basis of HU in the Hmong.
