Affi Ayuba, Josiah Mutihir, Dalili Shabbal, A. S. Longwan, T. S. Selowo, A. Lukden, Stephen Pam, Mercy Solomon
Open Journal of Obstetrics and Gynecology (OJOG) , 2018, DOI: 10.4236/ojog.2018.812126
Abstract: Background: In developing countries like Nigeria, with poor socio-economic, early marriage, poor acceptance of contraception, poor spacing of pregnancies, high fertility rate and poor maternal and child health indices, leading to poor maternal-child outcome. There is a need to investigate the pattern of serum lipid changes during pregnancy in Nigeria women as hyperlipidemia may lead to poor maternal outcome. Materials and methods: A total of one hundred and forty (140) subjects between the ages of 20 and 45 years with mean age 29.74 ± 6.5 years of the study population. Group 1: the control comprises of thirty-five (35) healthy non pregnant subjects with mean age of 26.84 ± 5.2 volunteers of Nigeria origin. Group 2: the test involved one hundred and five (105) apparently healthy pregnant Nigerian women sub-divided into three groups; X, Y and Z each made of thirty-five (35) subjects distributed into 1
On the recovery from the Little Ice Age  [PDF]

Natural Science (NS) , 2010, DOI: 10.4236/ns.2010.211149
Abstract: A number of published papers and openly available data on sea level changes, glacier retreat, freezing/break-up dates of rivers, sea ice retreat, tree-ring observations, ice cores and changes of the cosmic-ray intensity, from the year 1000 to the present, are studied to examine how the Earth has recovered from the Little Ice Age (LIA). We learn that the recovery from the LIA has proceeded continuously, roughly in a linear manner, from 1800-1850 to the present. The rate of the recovery in terms of temperature is about 0.5°C/100 years and thus it has important implications for understanding the present global warming. It is suggested on the basis of a much longer period covering that the Earth is still in the process of recovery from the LIA; there is no sign to indicate the end of the recovery before 1900. Cosmic-ray intensity data show that solar activity was related to both the LIA and its recovery. The multi-decadal oscillation of a period of 50 to 60 years was superposed on the linear change; it peaked in 1940 and 2000, causing the halting of warming temporarily after 2000. These changes are natural changes, and in order to determine the contribution of the manmade greenhouse effect, there is an urgent need to identify them correctly and accurately and remove them

Adnan Adil, Muhammad Masood, Matloob Ahmed
Sociology Mind (SM) , 2013, DOI: 10.4236/sm.2013.34044
Abstract:

Information & Communication Technology (ICT) usage in Pakistan is growing trend. However, while there is expanded concern of knowledge about how ICT is in usage in low income countries, there is information lacking on how ICT is used by the university teachers in low income countries. This research studied perception of university teachers about use of ICT, in Pakistani universities. The research through purposive sampling was drawn on 57 teachers, belonging to the public sector universities of Lahore, Punjab, Pakistan. This survey consisted of 29 males and 28 females. Their ages vary from 26 to 50 years. Open-ended questionnaire was used for this survey. It also showed that respondents have availability of internet at office. The association between different variables was calculated from chi-square test, and the strength of association was measured by gamma. The result showed the moderate negative association between level of age and quantity of daily time spent on computer. It also showed that no association exists between category of teacher’s gender and quantity of daily time spent on computer. For enhancement of ICT integration into education, it was recommended that teachers must have access to infrastructure relating ICT and there should be provision of sufficient training to teachers.

Dealing with Model Mis-Specification in the Analysis of Morale in Old Age  [PDF]

Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.21008
Abstract:

A major challenge for analysis of data from observational and survey studies is dealing with model mis-specification. A common reason for model mis-specification is the violation of the independence assumption. Model mis-specification is frequently due to the inclusion of variables that are correlated with the error terms (serial correlation) or due to variables omitted from the study. The application of standard regression models to such data could lead to over inflated results, i.e. erroneous results, and misleading conclusions. Longitudinally designed studies make substantial improvements and provide an additional handle to control omitted variables. However, even with longitudinal data, model mis-specification could occur because of the nature of observations, i.e. surveys often include objectively as well as subjectively measured variables. Subjective variables are respon

Surgical Science (SS) , 2014, DOI: 10.4236/ss.2014.53018
Abstract:

Objective: To estimate the impact of patient’s age on surgical outcomes in patients undergoing robotic hysterectomy. Methods: A retrospective review of prospectively collected cohort data for a consecutive series of patients undergoing gynecologic robotic surgery. Patient’s age and perioperative variables were collected from the database, charts, and other hospital records of all patients undergoing robotic hysterectomy. Results: 399 patients underwent robotic surgery for gynecologic disease. 370 patients who were under age 70 were compared with 29 patients who were over age 70. When comparing all patients under age 70 with patients over age 70, the mean age was 48.4 and 77 (P < 0.05), mean BMI was 32.1 and 28.3 kg/m2 (P < 0.05), mean procedure time was 185 and 211 minutes (min) (P = 0.09), mean console time was 123 and 148 min (P = 0.056), mean OR (Operating room) time was 237 and 273, mean EBL (Estimated blood loss) was 71 and 65 ml (P = 0.74), Hb (Hemoglobin) drop was 1.4 and 1.2 (P = 0.45), uterine weight was 212 and 95 gm (P = 0.98), and length of stay was 1.4 and 1.6 days (P = 0.33) (Table 1). The patients over age 70, when procedures were combined, had a statistically significant lower mean BMI, uterine weight and longer Operating room (OR) time. However, when stratified by the type of procedure performed, there was no difference in surgery times among those under 70 and over 70 years of age. The elderly patients were more likely to have cancer, which was in almost half the elderly patients, and thus necessitate staging. Thus adding the performance of lymph node dissection likely resulted in the increased length of the surgery time that was noted in the combined group (Tables 1,

Abstract:


Background: This study was undertaken to address the controversy regarding immunologic response to combination antiretroviral therapy (cART) among older patients. Methods: In a cross-sectional study all patients attending the HIV Clinic at Imam Khomeini Hospital (Tehran) from 2010 to 2011 were evaluated. Immunologic response was investigated using consecutive CD4+ T-cell counts in a one-year interval and outcomes were analyzed for older (>=50 yrs) and younger (<50 yrs) patients using SPSS version 16.0. Results: A total of 714 patients were actively enrolled in the clinic while 24 were 50 years or older, and had initiated ART; a similar random group of younger patients was selected as the control. Hepatitis C was the most prevalent co-infection in both groups. Patients with no serologic evidence of hepatitis B and C had significantly higher CD4+ T-cell counts than HIV/HBV co-infected patients after 12 months (p = 0.04). The average increased CD4+ T-cell counts in 6, 9, and 12 months of cART initiation were lower among older patients but the difference was not significant (50.75 vs. 123.08; p = 0.37, 132.87 vs. 710.58; p = 0.25, 271.27 vs. 500; p = 0.65). Conclusion: About 11% of the registered HIV-positive patients at our clinic were 50 years or older while their immunologic response to cART showed to be different. Specific needs of older HIV infected patients are highly recommended to be addressed in future treatment and care programs.

Case Reports in Clinical Medicine (CRCM) , 2015, DOI: 10.4236/crcm.2015.48056
Abstract: Introduction: Elderly patients represent a difficult category of surgical candidates for orthopedic surgery because they have multiple associated diseases and a high degree of osteoporosis. Presentation of Case: We present the case of a 103 years old woman with a pertrohanteric hip fracture treated successfully using a 135° dynamic hip screw. Discussion: There are many discussions about this kind of patients regarding postoperative complications, duration of hospitalization, stage of recovery and the patient’s status at discharge. Conclusion: We conclude that surgery may benefit patients who are over 100 year-old.

Adrian Furnham, John Crump
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.612147
Abstract: Over 6000 adult managers attending an assessment centre completed the MBTI and also specified in detail how long it had been before they were promoted to a managerial role, and also, where appropriate, to a senior managerial role. Correlational analyses showed shorter times to promotion were associated with being Extraverted and a Sensing Type. Regressions showed that Feeling types took longer to be promoted to managerial roles, and that Perceiving types took longer to be promoted to senior positions. Implications for the selection and management of people were considered.

"D.D. Farhud,M.S Kamali,M.Mahmoudi,R. Saffari "
Iranian Journal of Public Health , 1990,
Abstract: Three generations of women (3570 daughters, 1148 mothers and 131 grandmothers) from Tehran, Iran have been studied for menarcheal age. The results show that the age of onset of menarche has decreased in the present generation- 13.599, compared to 13.690 and 13.870 years, amount their mothers and grandmothers, respectively. These results, when compared with results obtained concerning the other Iranian groups, show the effect of both genetic and nongenetic factors on the onset of menarche.

Abstract: The aim of the study was to assess correlation level of dental and chronological maturity related to gender in a group of children of our population. Material and method: Total number of 320 girls and boys, 7 to 14 years old, participated in the study. Dental age assessed by Demirjian's method. Statistical data were analyzed by mean value and SD for dental maturity in age groups of 7, 8, 9, 10, 11, 12, 13 and 14 years for girls and boys, respectively. Calculating the equation of linear regression and the determination and correlation ratio assessed correlation level of dental and chronological age. Results and conclusion: According to the results obtained, it can be concluded that mean values of dental age are coinciding with the chronological maturity in all 8 age groups which is confirmed by high interdependence of dental and chronological maturity (78.6% for boys and 79.6% for girls). .
