The study aimed to assess the situation of orphans and vulnerable children (OVC) in Nigeria. It found that 10.2% of children were orphans and 24.5% were OVC. OVC had poor access to education, health, nutrition, shelter and care, and psychosocial protection. They also engaged in more high-risk behaviors like sexual exploitation and lacked awareness of HIV/AIDS prevention compared to other children. The report recommends strengthening policies and programs to improve coordination and targeting of services for OVC in Nigeria.

The negative impacts of adolescent sexuality problems among secondary school ...lukeman Joseph Ade shittu
This study was conducted to focus on the negative health outcomes related to sexual behaviour in adolescents and young adults attending public school in the Oworonshoki region of Lagos, Nigeria, Africa. Since, there is a relative dearth of knowledge on adolescents who face unique and challenging economics, health and education problems in our society. Data on the socio-demographic characteristics, prevalence and knowledge towards STD including HIV/AIDS, prevalence of sexual abuse practice/sexual behaviour, family planning awareness and acceptance including abortion practice were sorted out using self structured questionnaires and administered to 60% of student’s population using a stratified random sampling technique. 55.8% lived with both parents. While, 50.3% of the mothers had basic secondary school qualifications, 72.4% of them are traders. 61.5% had sex education were from misinformed friends/peers while 51% had no basic knowledge about sexual behavioral practice and attitude towards STDs/AIDS (HIV). STD has a prevalence of 34 and 41% of boys used condoms for preventing STI/HIV transmission and unwanted pregnancies. One out of every five sexually active teenagers has experienced forced sex, especially among the circumcised girls who were more sexually active than the uncircumcised girls. 60% of girls between ages of 12 and 18 years had more than one unsafe abortion with severe vaginal bleeding (haemorrhage) as the chief complication. However, 65% of the girls did abortion for fear of leaving school and financial hardship as the reasons.
Over the past decade, Kenya has made tremendous efforts to enhance maternal and child health. Secure maternity policies such as free maternity care are one of the initiatives that have enhanced maternal and child health in all public health facilities. Despite these attempts, public health facilities for maternal and child health are still underused. This study employed a cross-sectional descriptive study design to identify determinants of free maternal health services by evaluating factors determining perceptions and health-seeking behavior of 384 pregnant mothers in Malava Sub-County, Kakamega County. The study used a mixed-method (quantitative and qualitative approaches). Questionnaires were administered to pregnant mothers selected for the study. The study employed a purposive sampling of research participants. Quantitative data were collected using the questionnaire administered by the research assistants whereas qualitative data were collected by the researcher through interview schedules. Quantitative data analysis was carried out using SPSS 23. However, qualitative data were analyzed through content analysis. Quantitative data representation was done in terms of frequency and percentages. Analysis of chi-square testing was used to assess the association between the variables of socio-economic and health facilities and the provision of free maternity facilities (p<0.05). The study established that the uptake of free maternal service by pregnant mothers was influenced by their level of primitivism and religious beliefs. In addition, this study found out that 53.8% and 77.7% of the pregnant mothers could not attend antenatal and post-natal care because government facilities were located far away from their residences and they also had less access to some information about free maternal health care. The results of this research would be disseminated to the hospital management team, Sub-Country health management team, County health management team, and other stakeholders, thereby demonstrating reasons for low uptake of free maternity services and helping to strategize for better service delivery. Based on the finding, the study recommends that to improve access to free maternal health care, the county government ought to place health services as close as possible to the community where people live. Secondly, there is a need to embrace the usage of the existing media network to sensitize pregnant mothers to the danger signs and the need to have decision-making powers over their safety. Lastly, hospital management ought to increase the awareness of free maternal health care and to include it among the community priorities during dialog days, action days, and other group discussions.
In 2020 Aeroflow Urology surveyed over 1,000 women between the ages of 40 to 64 about how incontinence affects their daily lives.
The results showed that 72% of women had experienced incontinence, and 65% reported that they continue to experience it at least once per month.
The results pointed toward a lack of education around this area of women's health, as well as a lack of access to resources and support for women experiencing urological problems.

Superficial fungal infections are common among school-going children due to their involvement in practices that promote the spread at school or home. However, practices, knowledge and attitude of these children on prevention and control of fungal infection are poorly understood. This study assessed the practices, knowledge and attitude on the prevention and control of fungal infections among 163 children aged 5-12 years in western Kenya. A cross-sectional study design and systematic sampling method were adopted. Information on knowledge, attitude and practices on fungal prevention and control was collected using a structured questionnaire. Results showed that over 50% of the pupils had adequate knowledge on prevention and control of superficial fungal infections. On attitude, 58.9%of the children believed that those with fungal infection should not be allowed to play with others or go to school. Furthermore, 70.6% and 54.6% of the pupils agreed that sharing of toys and hairbrushes respectively leads in promoting the infections. These findings show that pupils demonstrate a good knowledge of superficial fungal with marked limited infection and control measures. Therefore, there is a need for stakeholders in health and education sectors to develop a policy framework involving learners in prevention and control of fungal infections.

Abstract—Obesity is the major global nutrition concern. Modernisation and urbanisation have led to changes in dietary and lifestyle factors which are contributing to the increased prevalence of overweight and obesity.
Objective: To find out various life style risk factors for obesity among school children of affluent families aged 10-18 years in Jaipur city.
Methods: A cross-sectional study in ten randomly selected schools of Jaipur city with tuition fee > 18000 ₹/year was conducted from July 2012 to April 2013. 1610 students of class V to XII were included and their detailed life style history with anthropometric measurements was recorded after their informed written consent. Indian Academy of Pediatrics' growth Monitoring Guidelines for children from birth to 18 years was followed for defining and classifying obesity.
Result: 364 (22.61%) participants were found obese/overweight. Watching television during meals, frequency of main meals outside home per month, frequency of snacks outside home per week and duration of television/ computer watching per day were found significant predictors of overweight/ obesity on binary multivariate logistic regression method.
Conclusion: The present study highlights childhood overweight/obesity is an emerging health problem (22.61%) and lifestyle factors are important risk for it.

A presentation by Bassam Abu Hamad, Dr Nicola Jones, Agnieszka Malachowska and Professor Sarah Baird to the 3rd Regional Conference: Investing in Healthier Generations in Amman, Amman, Jordan, December 2019
Background: With the widespread use of highly active antiretroviral therapy, the epidemic of HIV has evolved into a chronic disease. HIV is extremely stigmatizing, resulting in highly emotionally charged responses to disclosure. World Health Organization (WHO) recommends that children should be informed of their HIV status at ages of 6 to 12 years and full disclosure at about 8 to 10 years. Disclosure process is much more difficult when the person being disclosed to is an adolescent. However, disclosure of HIV to a child should be an ongoing process that may last several years depending on the cognitive development of the child.
Methods: This study investigated the determinants of HIV status disclosure among HIV infected adolescents. A total of 209 HIV infected adolescents (10-19 years) who have been on treatment for at least six months, and are taking lifelong anti-retroviral therapy from Bondo County Hospital, Got Agulu and Uyawi Sub County Hospital in Bondo Sub County were enrolled. Simple random sampling was employed in selecting the adolescents. Data was collected using a structured questionnaire. Quantitative data was analysed using both descriptive and inferential statistics while statistical tests including Pearson Correlation analysis and multiple linear regression were used to test the hypotheses.
Results: Findings on the overall parental perceptions regarding risks and benefits of disclosure and disclosure of HIV status to adolescents show that 180 (86.12%) of the respondents had a negative attitude compared to 29 (13.88%) who held a positive attitude. 122 (58.37%) of the respondents believed that overall availability and quality of counselling was moderate. 10 (4.78%) of the respondents believed that the overall availability and quality of counselling was high. Quality services and perception of the parents have been found to be good predictors of disclosure of HIV status among the newly diagnosed adolescents in Bondo sub-County, p-value<0.05.
Conclusion and recommendation: This study identified quality of service and perception of the parents as the two factors determining the disclosure of HIV status. There is a correlation between the parental perceptions regarding risks and benefits of disclosure and the quality of counselling to parental disclosure of HIV status to adolescents. Therefore the study recommends deliberate efforts to ensure quality service delivery and age specific disclosure counselling to caregivers to equip them with adequate knowledge on disclosure.

Couples presenting to the infertility clinic- Do they really have infertility...Sujoy Dasgupta
Dr Sujoy Dasgupta presented the study on "Couples presenting to the infertility clinic- Do they really have infertility? – The unexplored stories of non-consummation" in the 13th Congress of the Asia Pacific Initiative on Reproduction (ASPIRE 2024) at Manila on 24 May, 2024.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
