Sexual behaviours and their associated factors among young people in the Dodowa Health and Demographic Surveillance Site (DHDSS) in Ghana

Objective: This paper describes sexual behaviours and their associated factors among young people. Design: The study design is cross-sectional. Setting: Dodowa Health and Demographic Surveillance Site (DHDSS) in Ghana's Shai-Osudoku and Ningo Prampram districts. Participants: Young people aged 10 to 24 years, median age 17 years. Outcome measures: Self-reported to have ever had sex, non-use of a condom at last sex, and ever been pregnant or gotten someone pregnant. Results: Of the 1689 young people; 42% reported having ever had sex, not using a condom at last sexual activity (64%), and ever been pregnant or gotten someone pregnant (41%). The proportion of non-use of condoms at last sex was high across all age groups but was highest (93%) in a small proportion of 10 to 14-year-olds who have ever had sex. Higher proportions of females than males; were reported to have ever had sex (46%), not using a condom at their last sex (66%) and ever been pregnant or getting someone pregnant (56%). Age group (20 to 24), females, primary or junior high school, living alone and lower household socio-economic status were risk factors associated with all three outcome measures. Conclusion: Risky sexual behaviour is high among young people in the Dodowa HDSS. Therefore, interventions that promote safer sexual practices and help young people make timely decisions on their sexual and reproductive health care needs are required.

Challenges of accessing care in art clinic during COVID-19 lockdown in Lagos

Background: As the SARS-CoV-2 pandemic continues to ravage the world, its impact on the health systems and survival of people with chronic diseases especially People living with HIV [PLWH] could be undermined. It becomes relevant to assess the challenges PLWH face during this period to institute measures towards combating the negative effects of the pandemic. Aims: This study aims to investigate the challenges faced by PLWH in accessing care during the lockdown period in Lagos, Nigeria. The study was a cross-sectional one involving PLWH aged 18 years and above who presented for care. An interviewer-administered questionnaire was used to obtain information on demographic characteristics, their knowledge about COVID-19 disease, and challenges experienced in accessing care during the COVID-19-induced lockdown. Ethical approval was obtained from the Institution Research Ethics Board (IRB) of NIMR. Patients and Methods: Data generated from the survey was exported to Excel and analyzed using SPSS version 23.0. Results: The mean age of PLWH who participated in the study was 42.2 (±12.2) years. The majority were female (74.3%), married (66.3%), employed (58.9%), and on less than $100 monthly income (80.5%). The commonest challenges experienced were psychological (78.5%), financial (68%) and food (40.7%). There were significant association among the income status, lack of food (OR: 2.5, CI: 1.4-4.5, P = 0.002), financial challenges (OR: 1.7, CI: 1.0­3.0, P = 0.048) and psychological challenges (OR; 1.8, CI: 1.0-3.5, P = 0.05). Ninety­five percent of participants believed SARS-COV-2 infection is a viral infection. Conclusions: PLWH faces a myriad of challenges that would have a significant impact on their overall well-being and the gains of HIV care.

The role of serological testing in the SARS-CoV-2 outbreak

Antibody tests for the novel coronavirus, SARS-CoV2, have been developed both as rapid diagnostic assays and for high-throughput formal serology platforms. Although these tests may be a useful adjunct to a diagnostic strategy, they have a number of limitations. Because of the antibody and viral dynamics of the coronavirus, their sensitivity can be variable, especially at early time points after symptom onset. Additional data are required on the performance of the tests in the South African population, especially with regard to development and persistence of antibody responses and whether antibodies are protective against reinfection. These tests may, however, be useful in guiding the public health response, providing data for research (including seroprevalence surveys and vaccine initiatives) and development of therapeutic strategies

Microstructural observations on nissl substances in the cerebellar cortex of adult wistar rats following quinine administration

Purpose: This study assessed some microstructural effects of quinine; commonly used in malaria chemotherapy; especially in chloroquine-resistant and cerebral malaria; on the Nissl substance in the cerebellar cortex of adult Wistar rats using microanatomical studies. Methods: Twenty seven adult male Wistar rats; weighing between 150g and 190g; were randomly separated into groups A; B and C (n=9). The rats in group A served as the control and received intramuscular injection of physiological saline. Group B rats were injected intramuscularly with liquid quinine; 16mg/kg body weight as a start dose; followed by 8mg/kg body weight 8 hourly for seven days. Group C rats received the same treatment as group B but were subjected to a withdrawal period of one week. Groups A and B rats were sacrificed at the end of the treatment while group C rats were sacrificed at the end of one week. The cerebellum of each rat was removed and fixed in 10formol saline for histological analysis. Results: The findings showed that the Nissl substances in the cerebellar cortex in control rats stained more intensely and distinctly compared with the less intense stain and degenerated Nissl substances in the treated rats.Conclusion: The observed degenerative changes in the Nissl substances in the cerebellar cortex of the treated rats may affect the synthesis of proteins in correlation with neuronal functions

Ultrasonographic measurements of the hepatobiliary axis of children with sickle cell anaemia in steady state

Sickle cell anaemia is associated with structural manifestations in the hepatobiliary axis but these manifestations have not been sufficiently examined in Nigerian or African children. This study wasconducted to evaluate the results of ultrasono-graphic measurements of the hepatobiliary axis of children with sickle cell anaemia in a Nigerian teaching hospital. One hundred and twenty children with Hb SS in steady state aged between 12 months and 15 years and sixty children with Hb AA matched by age and sex (as controls) were consecutively recruited from April through November 2002. Past and present medical histories were obtained and physical examination and abdominal ultrasonography were performed. The mean liver span; the common hepatic duct and common bile duct diameters; the longitudinal and transverse dimensions (but not the wall thickness) of the gallbladder were significantly higher in test subjects than controls (p 0.05). Multiple regression showed that age correlated significantly with all the studied ultrasound scan (USS) measurements (p 0.05). Recurrent episodes of abdominal pain correlated with gallbladder wall thickness (p

Neonatal sepsis in a Nigerian Tertiary Hospital: Clinical features, clinical outcome, aetiology and antibiotic susceptibility pattern

Background: Neonatal sepsis is a significant cause of neonatal mortality in developing countries. The aetiological agents and their antimicrobial susceptibility patterns are dynamic.Objectives: This study determined clinical features, aetiology, antimicrobial susceptibility and clinical outcome of neonatal sepsis in a Nigerian Tertiary Hospital.Methods: Neonates undergoing sepsis evaluation at a Nigerian Tertiary Hospital were included in the study. Demographic and clinical information were obtained using standard questionnaires. Blood samples were cultured on MacConkey, Blood and Chocolate agar. Isolated bacteria were identified based on morphology, Gram stain appearance and standard commercially prepared biochemical tests. Antimicrobial susceptibility testing was performed on Mueller-Hinton agar using the Kirby-Bauer method.Results: Eighty-five of the 180 neonates admitted during the study period were recruited. Fifty-five neonates presented with early-onset sepsis and 30 with late-onset sepsis. Culture-proven sepsis was detected in 19 (22.4%) neonates. The incidence of culture-proven sepsis in the hospital was 2.8/100 live-births. The most common clinical feature at presentation was respiratory distress. Gram-negative bacteria accounted for 78.9 percent of all isolates and were the only organisms encountered in early-onset sepsis. Isolated pathogens were predominantly Klebsiella spp (31.6%), Enterobacter spp (21.1%) and coagulase-negative Staphylococci (15.8%). The isolates were most sensitive to ofloxacin. Gram-negative bacteria showed high resistance to cefuroxime and ampicillin. The case-fatality rate was 26%.Conclusion: Gram-negative bacilli, especially Klebsiella spp, was predominant. Neonatal sepsis persists as a cause of mortality in this region. Regular antimicrobial surveillance for empirical treatment remains an important component of neonatal care
