If the internal thoracic artery is a collateral circulation to the lower extremities, careful consideration should be given to its use when coronary artery bypass grafting is required. We report a case of CABG with bilateral common iliac artery lesions and collateral circulation from the bilateral ITAs on the peripheral side.
A 58-year-old man was admitted to our department with claudication and dyspnea upon exertion. He was diagnosed with right common iliac artery obstruction and 90% stenosis of the left common iliac artery. Coronary angiography revealed three-vessel disease with 50% stenosis of the left main trunk. The bilateral ITA showed a rich collateral flow to the lower extremities. Hybrid single staged repair with percutaneous transluminal angioplasty for the left iliac lesion was performed, followed by off-pump coronary artery bypass grafting (CABG) and femoro-femoral crossover bypass. Postoperative angiography revealed that all grafts were patent. The postoperative course was uneventful, except that the patient's creatinine kinase level increased to 7177 U/L on postoperative day 1.
To treat coronary artery disease with peripheral artery disease, especially those with iliac artery occlusion lesions with collateral circulation from the ITA, not only graft selection but also the treatment strategies for peripheral lesions are considered extremely important. Hybrid single staged coronary and lower limb artery revascularization could be safely achieved by multidisciplinary team strategies.

Despite the health and economic benefits of exclusive breastfeeding, there is evidence of a decline globally and in Ghana. Previous studies addressing this problem are mostly quantitative with only a few of such studies using qualitative or mixed methods to examine the predictors, benefits, ways of improving and managing exclusive breastfeeding, and the challenges associated with exclusive breastfeeding from the perspective of exclusive and nonexclusive breastfeeding mothers, and health workers. This study employs the health belief model to examine the experiences of mothers and health workers regarding exclusive breastfeeding to fill this gap in the literature.
A cross-sectional qualitative study involving in-depth interviews was conducted among health workers and mothers attending child welfare clinic at two polyclinics in Madina, Accra-Ghana in 2019. Purposive sampling was used to select health facilities and participants for the study. Twenty participants comprising ten exclusive breastfeeding mothershallenges and strategies employed in managing exclusive breastfeeding, emanates from mothers' personal experiences and interactions with institutional factors. In view of this, there should be counselling on the management of challenges associated withexclusive breastfeedingand provision of accurateinformation on exclusive breastfeeding to enable mothers practice exclusive breastfeeding.
Different levels of experience affect and shape exclusive breastfeeding practice in Ghana. The decision to practice exclusive breastfeeding, as well as the challenges and strategies employed in managing exclusive breastfeeding, emanates from mothers' personal experiences and interactions with institutional factors. In view of this, there should be counselling on the management of challenges associated with exclusive breastfeeding and provision of accurate information on exclusive breastfeeding to enable mothers practice exclusive breastfeeding.
Integral membrane protein 2A (ITM2A) is a transmembrane protein expressed in a variety of tissues; little is known about its function, particularly in the brain. ITM2A was found to be highly enriched in human brain versus peripheral endothelial cells by transcriptomic and proteomic studies conducted within the European Collaboration on the Optimization of Macromolecular Pharmaceutical (COMPACT) Innovative Medicines Initiative (IMI) consortium. Here, we report the work that was undertaken to determine whether ITM2A could represent a potential target for delivering drugs to the brain.
A series of ITM2A constructs, cell lines and specific anti-human and mouse ITM2A antibodies were generated. Binding and internalization studies in Human Embryonic Kidney 293 (HEK293) cells overexpressing ITM2A and in brain microvascular endothelial cells from mouse and non-human primate (NHP) were performed with these tools. The best ITM2A antibody was evaluated in an in vitro human blood brain barrier (BBB) model and in an inM2A is expressed in brain microvessels, but further investigations will be needed to demonstrate that ITM2A is a potential target for brain delivery.
The present work describes our efforts to explore the potential of ITM2A as a target mediating transcytosis through the BBB, and highlights the multiple challenges linked to the identification of new brain delivery targets. Our data provide evidence that antibodies against ITM2A are internalized in ITM2A-overexpressing HEK293 cells, and that ITM2A is expressed in brain microvessels, but further investigations will be needed to demonstrate that ITM2A is a potential target for brain delivery.
Increases in resistance to fluoroquinolones have been correlated with the use of levofloxacin in the treatment of infections caused by Escherichia coli. The analysis presents the in vitro activity of ceftazidime-avibactam and comparator agents against 10,840 levofloxacin-resistant E. coli isolates collected from four geographic regions (Africa/Middle East, Europe, Asia/South Pacific, Latin America) between 2012 and 2018.
Non-duplicate clinical isolates of E. coli were collected from participating centres and shipped to IHMA, Inc., (Schaumburg, IL, USA). Susceptibility testing was performed with frozen broth microdilution panels manufactured by IHMA, according to CLSI guidelines. N6F11 Levofloxacin-resistance was defined at a minimum inhibitory concentration of ≥ 2mg/L. Isolates collected between 2012 and 2015 were tested for extended-spectrum β-lactamase (ESBL) activity by determining susceptibility to cefotaxime, cefotaxime-clavulanate, ceftazidime, and ceftazidime-clavulanate as recommended by CLSI guidelinesns between 2012 and 2018 was consistently high. Susceptibility to the comparator agents colistin, tigecycline, imipenem and meropenem was also high.
Antimicrobial susceptibility to ceftazidime-avibactam among levofloxacin-resistant E. coli isolates, including ESBL-positive isolates, collected from four geographical regions between 2012 and 2018 was consistently high. Susceptibility to the comparator agents colistin, tigecycline, imipenem and meropenem was also high.
Both mild and conventional controlled ovarian stimulation are the frequently used protocols for poor ovarian responders. However, there are some debates about which treatment is better. Moreover, little is known about the follicular physiology after the two ovarian stimulation protocols. This study was intended to investigate the features in granulosa cells and follicular fluid micro-environment after the two different ovarian stimulation protocols in poor responders.
Granulosa cells RNA were sequenced using Illumina Hiseq technology. Specific differently expressed genes and proteins were verified by real-time quantitative PCR and Western blot analysis. Moreover, hormone and cytokine concentrations in the follicular fluid were measured by electrochemiluminescence immunoassay and enzyme-linked immunoabsorbent assay. The correlation between the results of molecular experiments and the laboratory outcomes were analyzed by Spearman correlation analysis.
The differentially expressed genes between the two grolation or the mild ovarian stimulation, showing that the TGF-β signaling pathway may correlate with the good-quality of embryos in the mild group, which may be instrumental to the choice of optimal management for IVF patients.
In addition to heterogeneity and artificial selection, natural selection is one of the forces used to combat climate change and improve agrobiodiversity in evolutionary plant breeding. Accurate identification of the specific genomic effects of natural selection will likely accelerate transfer between populations. Thus, insights into changes in allele frequency, adequate population size, gene flow and drift are essential. However, observing such effects often involves a trade-off between costs and resolution when a large sample of genotypes for many loci is analysed. Pool genotyping approaches achieve high resolution and precision in estimating allele frequency when sequence coverage is high. Nevertheless, high-coverage pool sequencing of large genomes is expensive.
Three pool samples (n = 300, 300, 288) from a barley backcross population were generated to assess the population's allele frequency. The tested population (BC
F
) has undergone 18 generations of natural adaption to conventional farming practological background and statistical robustness.
Patient journey maps are increasingly used as a tool that enables healthcare providers to refine their service provision to best meet patient needs. We developed a cervical dystonia patient journey map (CDPJM) that describes the holistic patient experience from pre-diagnosis through to long-term treatment.
The CDPJM was developed in 2 stages; a patient survey (open questions and multichoice) of 15 patients with CD was conducted to inform the design of the CDPJM, which was then refined and validated by an expert-patient focus group.
Qualitative analysis of the patient survey supported five key stages of the patient journey symptom onset, diagnosis and therapeutic relationship with healthcare professionals, initiation of care for CD, start of CD treatment, and living with treated CD. Following symptom onset, survey respondents described having multiple visits to their family doctor who prescribed strong pain killers and muscle relaxants and referred their patient to up to 10 different specialists for diagrest more and avoid going to work and experience life restrictions."
We present the first patient journey map for CD that can be used to guide local service mapping and to compare current provision with what patients say they want and need.

Acute thrombotic thrombocytopenic purpura (TTP) is an aggressive thrombotic microangiopathy that if not treated, can have a 90% mortality rate. Timely, extensive plasma exchange (PEX) has been indicated to reduce the mortality rate to < 10%, but its side effects are not well-known. We present here a case of a patient presented with Comb (+) TTP and developed catheter-associated deep vein thrombosis (DVT).
A 27-year-young man presented with persistent thrombocytopenia and Coombs positive anemia was firstly diagnosed with Evans syndrome. However, he was refractory to a methylprednisolone pulse therapy with a combination of platelet transfusion and eventually developed microangiopathy of central nerve system. Several pathological manifestations of the disease were prevented by PEX. The immediate start of PEX (1500mL/d) induced a complete remission of acquired TTP and disappearance of neurological signs and symptoms. However, external iliac and femoro-popliteal venous thrombosis was diagnosed subsequently, inferior vena cava filter (IVC) filter was immediately implanted accompanied with anticoagulation therapy.
