Three year's retrospective cohort studies on pulmonary TB incidence from 1987 to 1990 in Shanghai

Objective: To evaluate current clinical evidence for management of oral anticoagulation therapy after gastrointestinal bleeding (GIB) with an emphasis on whether to, when to, and how to resume an anticoagulation therapy. Data Sources: Relevant articles from MEDLINE, Cochrane Library, and EMBASE databases were identified from 1946 through May 20, 2017, using the keywords: gastrointestinal hemorrhage or gastrointestinal bleeding and antithrombotic therapy or anticoagulation therapy or warfarin or dabigatran or rivaroxaban or apixaban or edoxaban.Study Selection and Data Extraction: All English-language studies assessing management of oral anticoagulation therapy after GIB were evaluated. Data Synthesis: A total of 9 studies were identified. Four retrospective cohort studies showed that resuming anticoagulation therapy was associated with significantly lower rate of thromboembolism (TE) in the general population. Meta-analyses and prospective cohort studies also supported this finding. Two retrospective cohort studies indicated an increase in GIB when anticoagulation reinitiation occurred in less than 7 days without a decrease in TE. Resuming therapy between 7 and 15 days did not demonstrate a significant increase in GIB or TE. A large retrospective study showed that apixaban was associated with the significantly lowest risk of GIB compared with both rivaroxaban and dabigatran. Conclusion: Anticoagulation therapy resumption is recommended, with resumption being considered between 7 and 14 days following GIB regardless of the therapy chosen. Data for warfarin management after GIB should be applied with caution to direct oral anticoagulants (DOACs) because of the quicker onset and experimental nature of reversal agents. Apixaban may be a preferred option when restarting a DOAC therapy.

Clock Protein

The importance of circadian factors in managing patients is poorly understood. We present two retrospective cohort studies showing that lungs reperfused between 4 and 8 AM have a higher incidence (OR 1.12; 95% CI 1.03 to 1.21; p=0.01) of primary graft dysfunction (PGD) in the first 72 hours after transplantation. Cooling of the donor lung, occurring during organ preservation, shifts the donor circadian clock causing desynchrony with the recipient. The clock protein REV-ERBα directly regulates PGD biomarkers explaining this circadian regulation while also allowing them to be manipulated with synthetic REV-ERB ligands.

Retrospective Cohort Studies

Objective To investigate the relationship between maternal exposure to alcohol and low birthweight (LBW). Methods The literature search was performed in January 2017 using the following electronic databases: Medline, Embase, LILACS, SciELO, Web of Science, Scopus, CINHAL, Proquest, and PsychInfo. The search strategy used the following terms: alcohol drinking, binge drinking, alcohol-related disorders, alcoholism, alcohol addiction/use/abuse/consumption, light/moderate/social/low drinking, low birthweight, case-control studies, retrospective studies, and cohort studies. No restrictions regarding language or publication date were considered. The literature search yielded 2,383 articles, and after screening and eligibility assessment, 39 articles were included in the systematic review, and 38 studies were included in the meta-analysis. Results Maternal alcohol consumption was associated with LBW among retrospective cohort studies (relative risk [RR] = 1.37; 95%CI [confidence interval]:1.10–1.77; I2 = 98.4%; p < 0.01). Prospective cohort studies (RR = 1.11; 95%CI: 0.98–1.25; I2 = 81.5%; p < 0.01), and case-control studies (odds ration [OR] = 1.16; 95%CI: 0.68–1.97; I2 = 61.2%; p = 0.05) showed no association between alcohol and LBW. No publication bias was identified, and the meta-regression showed that the sample size influenced the high heterogeneity among retrospective cohort studies. The subgroup analysis showed differences in association between groups when compared by sample size, type of adjustment, or crude measures and publication year. Conclusions We have not found an association between alcohol consumption during gestation and LBW in the analysis in all of the subgroups. In addition, we have found a high heterogeneity between the primary studies, which is related to methodological differences in the conduction of these studies.
