This chronic infection is accompanied by prolonged cytokine production, which might affect the immuno-reproductive communication and favour the establishment of an adverse state. This was a prospective study designed to evaluate possible impact of some cytokine variations on menstrual cycle in TB infected females. Methods: A total of 90 premenopausal females aged (18-45) years were randomly recruited and grouped into 30 Symptomatic TB, 30 Symptomatic TB females on ATT and 30 Control females. Blood samples were collected at follicular (Fp) and luteal phases (Lp) of menstrual cycle for determination of IL-8, IL-6, TNFα, IL-4, CD4+ T-cells, and Absolute Lymphocytes counts using enzyme-linked immunosorbent assay (ELISA), Cyflow SL Green Cytometer and Sysmex K21N Hematology Analyzer respectively. Results: There was significantly higher IL-6, IL-8, IL-4 and TNFα with lower CD4 T-cells and Abs Lym counts in TB and TB on ATT compared to Control females at both phases of menstrual cycle (P<0.05). All the cytokines were significantly lowered with higher CD4 T-cells in TB on ATT compared to TB females at both phases (P<0.05). Hypogonadism correlated positively with pro and anti-inflammatory cytokines Conclusion: The study revealed significant cytokine alterations which suggest active inflammatory process while CD4 T-cells and Abs Lym dropped showing some degree of derangement in cellular immunity at both phases of menstrual cycle; which tends to normalize on treatment. This may affect the reproductive potentials in these women.","PeriodicalId":10369,"journal":{"name":"Clinical investigation","volume":"32 1","pages":"63-73"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75984254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Asthma is still poorly controlled in more than 50% of patients despite the availability of very effective drugs. GINA defined criteria for asthma control include asking about daytime symptoms, limitation of activity, night-time symptoms/awakenings and need for reliever treatment. Standardized and validated questionnaires such as asthma control test (ACT) help to assess the level of asthma control. Approximately 30 to 40% of asthmatic children are affected by sleep disturbances. Asthma symptoms during night-time must be seen as a special feature of asthma. Computerized cough, wheeze and respiratory rate monitoring provides additional and objective information on current night-time symptoms. To reduce risk for children with asthma, control of night-time symptoms is important to improve respiratory function and quality of sleep.","PeriodicalId":10369,"journal":{"name":"Clinical investigation","volume":"13 1","pages":"103-107"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79009464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim: To evaluate the independent association of systemic inflammation markers to HDL-C concentration, considering the relative contribution of envioromental, and metabolic factors, in a well-characterized Mexican-Mestizo population. Methods: We used logistic regression and linear regression analysis to assess the effect of inflammatory (high sensitivity C-reactive protein (hs-CRP), adiponectin, tumor necrosis factor alpha, interleukins 6, 10, 15, and 1β), environmental (diet and physical activity) and metabolic factors (triglyceride (TG) levels, insulin resistance, abdominal visceral fat) on HDL-C concentrations, in 907 adults (46.5% female, aged 52 ± 9 years), without diabetes, TG ≤ 600 mg/dL, and hs-CRP ≤ 3 mg/L. Results: We found hypoalphalipoproteinemia (HA: HDL-C ≤ 50 mg/dL in women and ≤ 40 mg/dL in men) in 44.8% of women and 48.8% of men. Carbohydrate intake (standardized coefficient β: -0.109 and -0.142), TG (-0.280 and -0.418), and interleukin-1β (-0.156 and -0.159) were inversely and independently associated to HDL-C levels, whereas adiponectin had a positive effect on the lipoprotein concentrations (0.196 and 0.169) for women and men, respectively (p<0.05 for all). Conjointly, these variables explained 33% of the variance in HDL-C levels. Conclusion: The study confirms the strong association of TG and carbohydrate intake with HDL-C levels. In addition, the results highlight the relevance of inflammatory processes in HA, which is one of the most prevalent cardiovascular risk factors in the Mexican population.","PeriodicalId":10369,"journal":{"name":"Clinical investigation","volume":"85 1","pages":"113-121"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90873327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to assess the predictive value of Q waves in inferior leads, alone or in combination with repolarization abnormalities, for the diagnosis of inferior wall myocardial infarction confirmed by imaging studies. Methods: Fifty-six patients, in whom computerized interpretation of the electrocardiogram resulted in the diagnosis of inferior wall myocardial infarction, and in whom imaging studies were also available, were included in this study. Electrocardiograms were performed using the GE MACHD 5500. Electrocardiograms were interpreted using the MUSE GE system. Echocardiograms and nuclear medicine cardiac imaging were performed and interpreted using standard equipment and techniques. S AS 9.3 software (SAS Institute, Inc., Cary, North Carolina) was used to calculate 95% exact binomial confidence intervals (CI) for the population PPVs. Results: Computerized interpretation of the ECGs leading to the diagnosis of old inferior wall myocardial infarction when compared with inferior wall myocardial infarction confirmed by imaging studies, had a positive predictive value of 52.78%. Adding the criteria of Q waves wider than 0.04 ms, using manual interpretation of ECG, increased the positive predictive value of the test to 80%. However, the presence of ST changes and/or negative or isoelectric T waves, in the presence of diagnostic Q waves in the inferior leads, increased the positive predictive value to 92%. Conclusion: These results suggest that the computerized interpretation of ECG results in a high rate of false positive readings of old inferior myocardial infarction. This may result in overutilization of imaging modalities. Presence of diagnostic Q waves in inferior leads, if accompanied by repolarization abnormalities, improves the accuracy of the electrocardiogram for the diagnosis of inferior wall myocardial infarction..","PeriodicalId":10369,"journal":{"name":"Clinical investigation","volume":"30 1","pages":"155-160"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79035126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Liprotamase is a biotechnology-derived, non-porcine, enzyme replacement without enteric coating. This study compared the effects of liprotamase and porcinederived pancrelipase on Coefficient of Fat Absorption (CFA) in patients with Exocrine Pancreatic Insufficiency (EPI) due to CF. Methods: We conducted a randomized, open-label, assessor blind, parallel group, multicenter, international trial to evaluate the noninferiority of liprotamase to porcine pancrelipase in 128 CF patients’ age ≥7 years with pancreatic insufficiency (Study NCT02279498). Subjects were randomized to liprotamase or pancrelipase, dose-matched to pre-study lipase doses. The primary endpoint was the between group difference in least square (LS) mean change from baseline in CFA, with a non-inferiority margin of -15% for the lower bound of the 95% confidence interval (CI). Key secondary endpoints compared treatment effects on CFA in the absence or presence of concomitant gastric acid suppression (GAS), and coefficient of nitrogen absorption (CNA). Results: Liprotamase missed the noninferiority criterion for CFA (95% CI -16.0, -7.7%), but met that criterion for CNA (95% CI -1.9, -0.7%). Concomitant GAS was associated with higher CFA with liprotamase but not pancrelipase. Conclusion: In this study, liprotamase was inferior to pancrelipase with regards to CFA, but not CNA. Higher doses and GAS may improve the efficacy of liprotamase.","PeriodicalId":10369,"journal":{"name":"Clinical investigation","volume":"5 1","pages":"147-154"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81043096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
