Congenital Anomalies in Neonates Admitted to a Tertiary Hospital in Southwest Ethiopia: A Cross Sectional Study

BackgroundCongenital anomalies affect 2–3% of all live births. Anomalies of the central nervous system account for the highest incidence followed by that of the cardiovascular and renal systems. There is scarcity of data in developing countries like Ethiopia. The aim of the study was determining the magnitude and type of congenital anomalies and associated factors in neonates admitted to the neonatology ward of Jimma Medical Center, Southwest Ethiopia.MethodsInstitution based cross sectional study was done from March 1 to July 30, 2020. A total of 422 mother-infant pairs were enrolled into the study. Structured questionnaires were used to capture the socio-demographic, obstetric and medical characteristics of the mothers, demographic characteristics of the infants and type of congenital anomalies. Univariate and multivariate logistic regression analyses were done and results are presented as narratives and using figures and tables.ResultsCloser to one in five neonates admitted to the neonatology ward (78, 18.5%, 95%CI 14.7–22.3) had congenital anomalies; the majority (59, 13.98%) having only one type of anomaly. Anomalies of the nervous system (29, 6.87%) and gastrointestinal system (24, 5.68%) accounted for the majority of the cases. Inadequate antenatal care follow-up (p=0.018, AOR=1.9, 95%CI1.115, 3.257) and lack of folate supplementation during pregnancy (p=0.027, AOR=2.35, 95%CI 1.101, 5.015) were associated with congenital anomalies in the neonates.ConclusionCongenital anomalies account for significant number of admissions. Significant association was seen between neonatal congenital anomalies and poor antenatal attendance and lack of folic acid supplementation during pregnancy.     

Ceramide changes in abdominal subcutaneous and visceral adipose tissue among diabetic and nondiabetic patients

BackgroundThis study profiles ceramides extracted from visceral and subcutaneous adipose tissue of human subjects by liquid chromatography‐mass spectrometry to determine a correlation with status of diabetes and gender.MethodsSamples of visceral and abdominal wall subcutaneous adipose tissue (n = 36 and n = 31, respectively) were taken during laparoscopic surgery from 36 patients (14 nondiabetic, 22 diabetic and prediabetic) undergoing bariatric surgery with a body mass index (BMI) >35 kg/m² with ≥1 existing comorbidity or BMI ≥40 kg/m². Sphingolipids were extracted and analyzed using liquid chromatography‐mass spectrometry.ResultsAfter logarithm 2 conversion, paired analysis of visceral to subcutaneous tissue showed differential accumulation of Cer(d18:1/16:0), Cer(d18:1/18:0), and Cer(d18:1/24:1) in visceral tissue of prediabetic/diabetic female subjects, but not in males. Within‐tissue analysis showed higher mean levels of ceramide species linked to insulin resistance, such as Cer(d18:1/18:0) and Cer(d18:1/16:0), in visceral tissue of prediabetic/diabetic patients compared with nondiabetic subjects and higher content of Cer(d18:1/14:0) in subcutaneous tissue of insulin‐resistant female patients compared with prediabetic/diabetic males. Statistically significant differences in mean levels of ceramide species between insulin‐resistant African American and insulin‐resistant Caucasian patients were not evident in visceral or subcutaneous tissue.ConclusionsAnalysis of ceramides is important for developing a better understanding of biological processes underlying type 2 diabetes, metabolic syndrome, and obesity. Knowledge of the accumulated ceramides/dihydroceramides may reflect on the prelipolytic state that leads the lipotoxic phase of insulin resistance and may shed light on the predisposition to insulin resistance by gender.     

Children who were vaccinated,breast fed and from low parity mothers live longer: A community based case-control study in Jimma,Ethiopia

Background  

Improving child survival through various health interventions has been one of the main preoccupations of public health programs in developing nations. However, efforts to understand the child death determinants and determine whether the health interventions are really contributing to the reduction of mortality were not satisfactory. The purpose of this study is to identify determinants and causes of child mortality.     

The goitre rate,its association with reproductive failure,and the knowledge of iodine deficiency disorders (IDD) among women in Ethiopia: Cross-section community based study

Background  

Iodine deficiency is severe public health problem in Ethiopia. Although urinary iodine excretion level (UIE) is a better indicator for IDD the goitre rate is commonly used to mark the public health significance. The range of ill effect of IDD is however beyond goitre in Ethiopia. In this study the prevalence of goitre and its association with reproductive failure, and the knowledge of women on Iodine Deficiency were investigated.     

Air pollution and daily hospital admissions in metropolitan Los Angeles

We used daily time-series analysis to evaluate associations between ambient carbon monoxide, nitrogen dioxide, particulate matter [less than and equal to] 10 microm in aerodynamic diameter (PM(10)), or ozone concentrations, and hospital admissions for cardiopulmonary illnesses in metropolitan Los Angeles during 1992-1995. We performed Poisson regressions for the entire patient population and for subgroups defined by season, region, or personal characteristics, allowing for effects of temporal variation, weather, and autocorrelation. CO showed the most consistently significant (p<0.05) relationships to cardiovascular admissions. A wintertime 25th-75th percentile increase in CO (1.1-2.2 ppm) predicted an increase of 4% in cardiovascular admissions. NO(2), and, to a lesser extent, PM(10) tracked CO and showed similar associations with cardiovascular disease, but O(3) was negatively or nonsignificantly associated. No significant demographic differences were found, although increased cardiovascular effects were suggested in diabetics, in whites and blacks (relative to Hispanics and Asians), and in persons older than 65 years of age. Pulmonary disease admissions associated more with NO(2) and PM(10) than with CO. Pulmonary effects were generally smaller than cardiovascular effects and were more sensitive to the choice of model. We conclude that in Los Angeles, atmospheric stagnation with high primary (CO/NO(2)/PM(10)) pollution, most common in autumn/winter, increases the risk of hospitalization for cardiopulmonary illness. Summer photochemical pollution (high O(3)) apparently presents less risk.     

Young adult and middle age mortality in Butajira demographic surveillance site,Ethiopia: lifestyle,gender and household economy

Background  

Public health research characterising the course of life through the middle age in developing societies is scarce. The aim of this study is to explore patterns of adult (15–64 years) mortality in an Ethiopian population over time, by gender, urban or rural lifestyle, causes of death and in relation to household economic status and decision-making.     

Differences between measured and resultant joint moments during voluntary and artificially elicited isometric knee extension contractions

OBJECTIVE: Examine two hypotheses: (a) during isometric knee extension contractions the moment measured at the dynamometer is different from the resultant moment in the same plane around the knee joint and (b) during isometric contractions, at the same given resultant moment the knee angle while loading is different from the knee angle while unloading. DESIGN: Comparative study in which the geometrical and the kinetic differences between joint and dynamometer were determined. BACKGROUND: It is usually assumed that the moment measured by the dynamometer is equivalent to the resultant joint moment. The non-rigidity of the dynamometer-leg system can influence the equivalence of these two moments. METHOD: Twenty seven subjects performed isometric maximal knee extension contractions and contractions induced by electrostimulation on a dynamometer. The kinematics of the leg were recorded using 8 cameras (120 Hz). RESULTS: The resultant moment at the knee joint and the moment measured by the dynamometer are different. During a knee extension effort the knee angle changes significantly. At identical resultant knee joint moments the knee angles are different when comparing the loading and the unloading phases. CONCLUSIONS: The differences between the measured and the resultant joint moments might influence the estimation of parameters as: muscle forces, moment-angle relationship and strain and hysteresis of tendons and aponeuroses. RELEVANCE: Torque dynamometers have been often used to estimate muscle forces, to examine neuromuscular processes and to determine the mechanical properties of tendons and aponeuroses.     

Tissue factor pathway inhibitor-2 (TFPI-2) recognizes the complement and kininogen binding protein gC1qR/p33 (gC1qR): implications for vascular inflammation

Evidence is accumulating to suggest that TFPI-2 is involved in regulating pericellular proteases implicated in a variety of physiologic and pathologic processes including cancer cell invasion, vascular inflammation, and atherosclerosis. Recent immunohistochemical studies of advanced atherosclerotic lesions, demonstrated a similar tissue distribution for TFPI-2, High Molecular Weight Kininogen (HK), and gC1qR/p33 (gC1qR), a ubiquitously expressed, multicompartmental cellular protein involved in modulating complement, coagulation, and kinin cascades. Further studies to evaluate TFPI-2 interactions with gC1qR demonstrated direct interactions between gC1qR and TFPI-2 using immunoprecipitation and solid phase binding studies. Specific and saturable binding between TFPI-2 and gC1qR (estimated Kd: approximately 70 nM) was observed by ELISA and surface plasmon resonance (Biacore) binding assays. Binding was inhibited by antibodies to gC1qR, and was strongly dependent on the Kunitz-2 domain of TFPI-2, as deletion of this domain reduced gC1qR-TFPI-2 interactions by approximately 75%. Deletion of gC1qR amino acids 74-95, involved in C1q binding, had no effect on gC1qR binding to TFPI-2, although antibodies to this region and purified C1q both inhibited binding, most likely via allosteric effects. In contrast, HK did not affect TFPI-2 binding to gC1qR. Binding of TFPI-2 to gC1qR produced statistically significant but modest reductions in TFPI-2 inhibition of plasmin, but had no effect on kallikrein inhibition in fluid phase chromogenic assays. Taken together, these data suggest that gC1qR may participate in tissue remodeling and inflammation by localizing TFPI-2 to the pericellular environment to modulate local protease activity and regulate HK activation.
