The New Invincibles: HIV Screening among Older Adults in the U.S

Background Thirteen percent of the U.S. population is ages 65 and older, a number projected to reach 20% by 2030. By 2015, 50% of Human Immunodeficiency Virus (HIV)-infected individuals in the U.S. are expected to be ages 50 and older. Current Centers for Disease Control and Prevention guidelines recommend “opt-out” HIV screening for individuals ages 13–64. The purpose of this study was to assess the occurrence and barriers to HIV screening in older adults, and to evaluate the rationale for expanding routine HIV screening to this population. Methods The study used 2009 National Health Interview Survey (NHIS) data. A total of 12,366 (unweighted) adults, ages 50 and older, participated in the adult section of the NHIS and answered questions on the HIV/AIDS, Sexually Transmitted Diseases, and Tuberculosis components. Associations between HIV screening, socio-demographic variables, and knowledge of HIV-related disease were examined using logistic regression models. Results The HIV screening rate within this population was 25.4%. Race had no statistically significant effect. Low risk perception of HIV exposure (84.1%) accounted for low likelihood of planned screening (3.5%) within 12 months post survey. A routine medical check-up was the single most common reason for HIV screening (37.6%), with only about half (52.7%) of the tests suggested by a health care provider. Conclusion It is imperative that practices and policies are developed and implemented to increase HIV awareness and screening in the older adult population. Increased health care provider awareness of the importance of HIV screening, especially for those 65 and older, is critical. Health policies and clinical guidelines should be revised to promote and support screening of all adults.

The effects of malaria and HIV co‐infection on hemoglobin levels among pregnant women in Sekondi‐Takoradi, Ghana

To assess the burden of maternal malaria and HIV among pregnant women in Ghana and to determine the risk of anemia among women with dual infection.

Adolescent pregnancy and the risk of Plasmodium falciparum malaria and anaemia—A pilot study from Sekondi-Takoradi metropolis, Ghana

The problem of malaria in adolescence has been surpassed by the immense burden of malaria in children, most especially less than 5. A substantial amount of work done on malaria in pregnancy in endemic regions has not properly considered the adolescence. The present study therefore aimed at evaluating the prevalence of Plasmodium falciparum and anaemia infection in adolescent pregnant girls in the Sekondi-Takoradi metropolis, Ghana. The study was carried out at four hospitals in the Sekondi-Takoradi metropolis of the western region of Ghana from January 2010 to October 2010. Structured questionnaires were administered to the consenting pregnant women during their antenatal care visits. Information on education, age, gravidae, occupation and socio-demographic characteristics were recorded. Venous bloods were screened for malaria using RAPID response antibody kit and Geimsa staining while haemoglobin estimations were done by cyanmethemoglobin method. The results revealed that adolescent pregnant girls were more likely to have malaria infection than the adult pregnant women (34.6% verses 21.3%, adjusted OR 1.65, 95% CI, 1.03-2.65, P=0.039). In addition, adolescent pregnant girls had higher odds of anaemia than their adult pregnant women equivalent (43.9% versus 33.2%; adjusted OR 1.63, 95% CI, 1.01-2.62, P=0.046). Taken together, these data suggest that adolescent pregnant girls were more likely to have malaria and anaemia compared to their adult pregnant counterpart. Results from this study shows that proactive adolescent friendly policies and control programmes for malaria and anaemia are needed in this region in order to protect this vulnerable group of pregnant women.

Overdiagnosis and overtreatment of malaria in children in a secondary healthcare centre in Sekondi-Takoradi, Ghana

Overdiagnosis and overtreatment of malaria is a major problem in children in malaria-endemic countries. This retrospective study identified children who were admitted with fever and were treated with or without anti-malarial medications and discharged at the Paediatric Unit of the Effia-Nkwanta Regional Hospital. The medical records of all children were searched, retrieved and assessed. A total of 1160 records from children (age range, 0–12 years) were reviewed and evaluated. Of the total number, 21.3% had laboratory confirmed malaria, 38.4% were malaria negative, while 40.3% had no malaria tests performed. In addition, the results showed that 4.5% of the laboratory confirmed malaria positive cases were not given anti-malarial medication while 84.1% of the malaria negative cases were given these incorrectly. Furthermore, 78.2% of the children with no malaria tests were prescribed anti-malarial medication. The presumptive diagnosis of malaria should be abandoned and the installation of a functional laboratory services promoted.

The Effect of Educational Attainment on HIV Testing Among African Americans

A person is infected with human immunodeficiency virus (HIV) every nine and half minutes in the United States., Moreover, one in five people infected with HIV in the United States does not know their status. While African Americans make up just 14% of the United States population, they constitute 44% of new HIV infections each year in the United States.4 This study examined the relationship between level of education and HIV testing among African Americans. A sample of 3,254 African American men and women between 18–84 years of age was isolated from the 2008 National Health Interview Survey and analyzed. The results revealed that African Americans with greater educational attainment (high school diploma or greater) are more likely to report having been tested for HIV than those who have not graduated from high school.

Evaluation of Blood Transfusions in Anemic Children in Effia Nkwanta Regional Hospital, Sekondi-Takoradi, Ghana

Blood transfusion is a common practice in sub-Saharan Africa as a way of correcting anemia in children with mild and severe sicknesses. This study evaluated this practice in a secondary health-care institution in Ghana. A retrospective study was done over a 3-year period from January 2010 to December 2012. Medical records of children admitted, successfully treated, and discharged from the hospital were collected and analyzed. Data were analyzed using Epi Info version 7. Transfusions were more among male children (89, 63.1%) than female children (52, 36.9%). The highest number of blood transfusions were carried out on children in the age range 0-1 year (66, 46.8%). The majority of the blood transfusions were done on children with hemoglobin concentration level of 5 g/dL and below. Children with malaria parasitemia (83, 58.9%) had more transfusions than children without malaria parasitemia (58, 41.1%). Fever alone (43, 30.5%) and fever with gastrointestinal symptoms (33, 23.4%) were the predominant symptoms among children who had blood transfusions. In conclusion, younger children received more transfusions than older children. Also, male children received more blood transfusions than female children. Malaria was observed as a major contributory factor to the requirement for blood transfusions among the children.

Prevalence of intermittent preventive treatment with sulphadoxine-pyrimethamine (IPTp-SP) use during pregnancy and other associated factors in Sekondi-Takoradi, Ghana.

BACKGROUND Intermittent preventive treatment in pregnancy (IPTp) with sulphadoxine-pyrimethamine (SP) has been adopted as policy by most countries in sub-Saharan Africa. This cross-sectional study assessed the prevalence of IPTp-SP usage for prevention of malaria among pregnant women as well as evaluated factors associated with IPTp-SP use during pregnancy in Sekondi-Takoradi region of Ghana. METHODS Pregnant women attending their antenatal-care with either clinical/ultrasound evidence of pregnancy were recruited. Venous blood was screened for malaria using RAPID response antibody kit and Giemsa staining. Haemoglobin estimations were done by cyanmethemoglobin method while Human Immunodeficiency Virus (HIV) screening was performed by the national diagnostic algorithm of two rapid antibody test and western blot confirmation. RESULTS Of the 754 consented pregnant women interviewed in this study, 57.8% had received IPTp-SP while 42.2% had not at their first contact with the study personnel. Furthermore, 18.6% (81/436) of those that received IPTp-SP were malaria positive while 81.4% (355/436) were malaria negative. The results also indicated that 47.7% (51/107) of the pregnant women in their third trimester who were meant to have received at least two-doses of SP had received ≥2 doses while 35.5% (38/107) had received 1 dose. In multivariable logistic regression analysis, pregnant women in their third trimester who received ≥2 doses of SP showed decreased likelihoods of malaria (adjusted OR, 0.042; 95% CI, 0.003-0.51; P = 0.013). CONCLUSION IPTp-SP usage among pregnant women in Sekondi-Takoradi reduces malaria and its use for malaria prevention should be strengthened with proper dosage completion and coverage.

Malaria and associated co-morbidity in children admitted with fever manifestation in Western Ghana: A retrospective study

INTRODUCTION Children under five years of age are highly vulnerable to malaria infection and often face dire consequences such as severe malaria if they are not promptly and adequately treated with effective anti-malarial medications. We set out to evaluate malaria and associated co-morbidity among children admitted with febrile illness in Sekondi-Takoradi, Ghana. METHODOLOGY This retrospective study focused on children admitted with fever over a three-year period at the pediatric unit of Effia-Nkwanta Regional Hospital. The children were identified, and the medical records of those who were successfully treated and discharged were searched, retrieved, and reviewed. RESULTS A total of 1,193 children were identified and selected for analysis. The mean duration of admission increased from 2.17 days in 2010 to 3.36 in 2012. Conversely, the mean age decreased from 3.85 years in 2010 to 2.74 in 2012. Overall, laboratory-confirmed malaria prevalence decreased; however, this decrease was only observed among children five years of age or younger, while malaria prevalence increased among children one year of age or younger. The proportion of children with severe malarial anemia significantly increased, while the proportion of those with mild malaria decreased significantly. CONCLUSIONS Despite the general decrease in malaria morbidity seen in this study, children younger than one year of age remain at increased risk of malaria morbidity. With an increase in malaria prevalence among children younger than one year of age over the three years of study, integrated and targeted control measures are highly needed for this age group.

Evaluating the knowledge of sickle cell disease and hemoglobin electrophoretic pattern among people living in Sekondi-Takoradi Metropolis, Ghana

Background: Sickle cell disease (SCD) is an inherited lifelong hemolytic disorder affecting many children in sub-Saharan Africa, especially in West and Central Africa. There is a limited public health education on SCD in Ghana with only two information centers in Accra and Kumasi, respectively. Methodology: This cross-sectional study evaluated the knowledge of SCD among people living in Sekondi-Takoradi metropolis. Churches, saloons, internet cafes and bus stations were randomly selected in the center of the city with proximity to the central market. Results: A total of 621 individuals were recruited, 52.5% (326) had knowledge of their hemoglobin (Hb) electrophoretic pattern while 47.5% (295) had none. In addition, 93.4% individuals had knowledge of SCD while 6.6% had no knowledge of SCD. Older individuals exhibited better knowledge of their Hb electrophoretic pattern than the younger ones (P = 0.019). Individuals with tertiary education and married couples exhibited higher knowledge of SCD when compared to their counterparts (P Conclusion: Despite the relatively high knowledge of SCD and Hb electrophoretic pattern observed in this study, it is very important to increase neonatal screenings and health care services to the region. In addition, more emphasis is needed to increase public awareness of SCD especially in schools, churches, hospitals and the media.

Influence of Education on HIV Infection among Pregnant Women Attending their Antenatal Care in Sekondi-Takoradi Metropolis, Ghana

This study investigated the influence of the level of education on HIV infection among pregnant women attending antenatal care in Sekondi-Takoradi, Ghana. A cross-sectional study was conducted at four hospitals in the Sekondi-Takoradi metropolis. The study group comprised 885 consenting pregnant women attending antenatal care clinics. Questionnaires were administered and venous blood samples were screened for HIV and other parameters. Multivariable logistic regression analyses were performed to determine the association between the level of education attained by the pregnant women and their HIV statuses. The data showed that 9.83% (87/885) of the pregnant women were HIV seropositive while 90.17% (798/885) were HIV seronegative. There were significant differences in mean age (years) between the HIV seropositive women (27.45 ± 5.5) and their HIV seronegative (26.02 ± 5.6) counterparts (p = .026) but the inference disappeared after adjustment (p = .22). Multivariable logistic regression analysis revealed that pregnant women with secondary/tertiary education were less likely to have HIV infection compared with those with none/primary education (adjusted OR, 0.53; 95% CI, 0.30–0.91; p = .022). Our data showed an association with higher level of education and HIV statuses of the pregnant women. It is imperative to encourage formal education among pregnant women in this region.
