Congenital tuberculosis (TB) is rare and the prognosis is poor if not detected early. The diagnosis is often delayed owing to non-specific clinical presentation, misdiagnosis and undiagnosed maternal TB during pregnancy. A 12-day-old girl presented with a 5-day history of fever, cough, poor feeding and respiratory distress. Her mother had a cough and fever at 30 weeks gestation which was managed empirically as community-acquired pneumonia without a TB workup. Immediately postpartum, her mother developed a high fever and shortness of breath and required admission to the intensive care unit. The infant was separated from her mother after delivery. The infant's chest radiograph showed bilateral miliary nodules. Thoracic and abdominal computed tomography (CT) showed multiple enlarged lymph nodes and congenital TB was suspected. Early morning gastric aspirate and sputum (obtained through a suction tube) were positive for acid-fast bacilli on smear microscopy and subsequently Mycobacterium tuberculosis was cultured from both specimens. Lumbar puncture was performed and cerebrospinal fluid (CSF) was compatible with TB meningitis. TB-polymerase chain reaction (TB-PCR) was positive. Her mother was diagnosed with miliary TB on postpartum day 17. Both were given anti-TB chemotherapy. BI-2493 cell line Unfortunately, despite the treatment, the infant died from multiple organ dysfunction syndrome (MODS) caused by congenital TB at the age of 14 days. This case highlights the importance of screening pregnant women for TB in regions where it is highly prevalent. A high index of suspicion of maternal and congenital TB is critical to early diagnosis, especially in such regions.Activation of protein kinase A by cyclic AMP results in a multi-fold upregulation of CaV1.2 currents in the heart, as originally reported in the 1970's and 1980's. Despite considerable interest and much investment, the molecular mechanisms responsible for this signature modulation remained stubbornly elusive for over 40 years. A key manifestation of this lack of understanding is that while this regulation is readily apparent in heart cells, it has not been possible to reconstitute it in heterologous expression systems. In this review, we describe the efforts of many investigators over the past decades to identify the mechanisms responsible for the β-adrenergic mediated activation of voltage-gated Ca2+ channels in the heart and other tissues.We report a rare case of tetralogy of Fallot with dextrocardia and anomalous coronary artery. Although this is an unusual complex disease, we have successfully repaired it with a combination of transatrial/transpulmonary and trans-right ventricle techniques.Background Rubella continues to be a leading cause of vaccine-preventable congenital birth defects and permanent organ damage, especially in developing countries. For women who are infected with the rubella virus (RV) before conception or during the first trimester of pregnancy, the unborn child has up to a 90% probability of developing congenital rubella syndrome. There are limited data on the seroprevalence of the rubella virus among pregnant women in Sub-Saharan Africa. Therefore, the aim of this study was done to determine the pooled seroprevalence of rubella among pregnant women in Sub-Saharan Africa.Methods The PRISMA guidelines protocol was followed to write the systematic review and meta-analysis. Published studies were searched in Medline, PubMed, Google scholar, advance google and Cochrane Library. The search terms on the databases are "rubella"OR "rubeo*", "rubella"AND"seroepidemiology", "seroprevalen *" OR "prevalen*", "seroprevalen *" OR "seroimmun*", "rubella antibod*"AND "pregnan*", "seroprevalen *" AND "sub-Saharan Africa".The heterogeneity of studies was weighed using Cochran's Q test and I2 test statistics. Publication bias was assessed by using Egger's and Begg's test.Results Twenty-eight studies were included in this meta-analysis. The pooled seroprevalence of anti-RV IgG among pregnant women in Sub-Saharan African was 89.0% (95%CI 84.6-92.3), and the pooled prevalence of anti-RV IgM among pregnant women in Sub-Saharan Africa was 5.1% (95%CI 2.6-9.9).Conclusion This meta-analysis showed that seronegativity and acute infection with RV among pregnant women in sub-Saharan Africa is high compared to other studies and the WHO threshold among women of child-bearing age. This finding calls for primary health care providers to make the community aware of this rubella-susceptible group and its healthcare burden, with the desired outcome that sub-Saharan Africa countries would introduce an implementation strategy for rubella vaccination of pregnant women and women of child-bearing age.Cellular dynamics of KORRIGAN 1 (KOR1) is closely linked with cellulose biosynthesis and plant osmotic stress tolerance. Cycling of KOR1 between the plasma membrane (PM) and trans-Golgi Network (TGN) is maintained by sequence motifs and protein structures that are recognized by cellular transport and quality control mechanisms. Several mutations in KOR1, as well as in the host genetic background, promote the mistargeting of KOR1 and induce KOR1 accumulation in the tonoplast (TP). Yet, little is known about how retention and sorting of KOR1 are regulated in the PM-TGN cycle. Forward genetic screening for GFP-KOR1 mislocalizing phenotype resulted in several mutant lines with different localization patterns or signal intensity of GFP-KOR1. One of the identified mutants were disrupted at UDP-glucoseglycoprotein glucosyltransferase (UGGT) locus, which is essential for the protein quality control in the ER. Our finding suggests the mis/unfolded structure of KOR1 triggers the TP targeting.Sclerostin is a protein synthesized mainly by osteocytes whose function is to inhibit bone formation. A recent monoclonal antibody, Romosozumab, is able to block sclerostin. The aim of this meta-analysis is to compare the safety of Romosozumab with placebo and alendronate. Five randomized controlled trials that described the safety of Romosozumab in healthy men and postmenopausal women were analyzed. The measures to be compared were the number of adverse events and the number of serious adverse events. Specific results included injection site reaction, arthralgia, nasopharyngitis, and back pain. A total of 11,741 patients were included in this meta-analysis, in three different groups Romosozumab, alendronate, and placebo. Significant differences were seen between the groups with regard to injection site reaction 5.88% in the Romosozumab group versus 3.62% in the placebo group (Mantel-Haenszel [M-H] 1.54, confidence interval [95% CI] 1.22-1.96; p  less then  0.001) and 2.62% in the alendronate group (M-H 1.8, 95% CI 1.
