Factors Associated with Home Births among Rural Mothers in Uganda; a Descriptive Survey of Gomba District

In Uganda, about 16 mothers die daily due to pregnancy, childbirth complications or within the first six weeks after delivery. For each maternal death, at least six mothers sustain permanent or temporary disabilities and morbidities. Until now, nearly 42% of the women still deliver at home and yet, 94% of them attend antenatal care at least once. Factors for the persistence of home births among mothers in rural areas of Uganda were therefore investigated to specifically determine the association between social demographic characteristics and home births, the impact of village health teams and the role played by sexual partners in influencing home births.

To Analyze the Casual Effect of Economic Growth, Energy Use on Fossil Fuel Consumption in Sub Saharan Africa with Structural Breaks

The study seeks to investigate the casual effect of the efficient energy use and GDP (economic growth) on fossil fuel consumption (Nonrenewable) for the sub Saharan Africa for the period 1980 to 2014. The study also seeks to investigate solutions to environmental issues. Zivot-Andrews unit root test with a structural break, Phillips and Perron unit root test with structural break revealed that the investigated variables become stationary at first-differences. The Gregory-Hansen cointegration test with a structural break shows efficient energy use, economic growth and energy consumption are co-integrated. The long-run estimates obtained from the VECM model indicate that in account of the changes in the structure of the economies, the environmental Kuznets curve does not exist due to validity of a U shaped curve. An increase in output growth (GDP) and efficient energy use positively affect environmental pollution. Based on the findings of this study, the study recommends investment in green technology as the economy growths.

First Known Case of Juvenile Gigantomachia in the United Kingdom - A Case Report

Gigantomastia is a rare condition which remains poorly understood. There is no universally accepted definition, however breast weight exceeding 3% of total body weight has been proposed. Juvenile gigantomastia, a subtype, involves sudden onset, excessive growth of breast tissue in relation to puberty and can occur before or after the onset of menstruation. This paper reports on the first known case of juvenile gigantomastia seen in the United Kingdom. A 16-year old female presented with a 12-month history of rapid breast growth. She had no other medical problems and no relevant family history. Examination revealed bilaterally enlarged breasts extending to the level of the anterior superior iliac spine, with enlarged superficial veins, ill-defined areola and areas of skin ulceration. A range of hormone and autoimmune tests were performed with all results found to be normal. After MDT discussion, the treatment of choice was reduction mammoplasty with an inferior pedicle technique and free nipple grafting if necessary. The total volume of tissue removed weighed 10.9 kg; 6.6 kg from the right breast, 4.3 kg from the left breast. Initial post-operative results demonstrate a highly satisfactory reduction with minimal scarring and no further growth of breast tissue. Histology showed a benign pattern secondary to extensive proliferation of glandular and stromal tissue. The tissue tested positive for both oestrogen and progesterone receptors and so the decision was made to treat the patient with tamoxifen until the age of 21 years in order to prevent recurrence. To our knowledge, this is the first reported case of juvenile gigantomastia in the UK.

Predictive Value of ERCC1 Expression on Treatment Response to Cisplatin-Based Regimens in Small Cell Lung Cancer: A Retrospective Analysis

We aimed to determine whether the excision repair cross-complementation group 1 (ERCC1) expression predicts response to cisplatin-based chemotherapy in patients with small cell lung cancer (SCLC). This was a retrospective study, in which hospital files of 31 patients (29 males, 2 females; mean age, 62.26±7.71 years) were reviewed. All patients were treated with etoposide+cisplatin. The lung biopsy and mediastinal lymph node samples were applied anti-human monoclonal antibodies against ERCC1: immunohistochemical staining was considered positive if 25-100% of the cells showed nuclear staining, and negative if less than 25% of the cells showed negative or slight staining. Response to treatment was evaluated as regression (complete or partial response), progressive disease, or stable disease. Of the patients, 18 (58.1%) had limited-stage, and 13 (41.9%) had extensive-stage SCLC. Median follow-up duration was 15 months (range: 1-60 months). ERCC1 staining was positive in 9 of 31 patients (29.0%). In 12 patients (38.7%), tumor regression (complete or partial response) was obtained after chemotherapy. Tumor regression rate was higher in ERCC1 positive patients than those with negative ERCC1 expression (66.7% vs. 27.3%, p=0.036). In conclusion, high expression of ERCC1 was associated with higher response rate to cisplatin-based regimens in patients with SCLC.

Ampullary Localization of Unruptured Ectopic Pregnancy of Eighteen Weeks about a Case

Ectopic pregnancy is therefore implanted out of the normal implantation site of the uterine cavity. It is a surgical emergency that can compromise the vital prognosis and fertility of patients when the diagnosis is made at the stage of rupturing. Its incidence has doubled or even tripled in the world in the last two decades. Although it still remains the leading cause of maternal mortality in the first trimester by tubal rupturing accounting for 13% of maternal deaths this increase is closely linked to several factors such as sexually transmitted infections, history of salpingitis, tubal surgery, abortions, inert or progesterone associated IUD use and smoking. Tubal location is by far the most common (96 to 99% of cases). The clinical signs are therefore relatively late and the rupture of the tube is preceded by a fissure syndrome. We report a rare case of unruptured ampullary pregnancy that has evolved to 18 weeks.

Anodizing for Design and Function

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.

Electronic-nose Applications in Forensic Science and for Analysis of Volatile Biomarkers in the Human Breath

The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.
