Asian Journal of Advances in Medical Science, Volume 4, Issue 4, Page 5-11

Polyunsaturated fatty acids (PUFAs) are a vital component for human health. PUFA cannot be synthesized by human system and hence dependance on other sources has become inevitable.

Though porcine liver and fish oil were the dependable sources for ages past, yet cheaper microbial source was sought after and have gained importance as well. Such microbial oils normally used as biofuels can also be used for several therapeutic purposes. Hence, this study was designed to evaluate the quality and quantity of lipids produced by a probiotic yeast, Rhodotorula mucilaginosa. The lipid production potential of Rhodotorula mucilaginosa has indeed attracted a lot of attention. Isolation and characterization of the probiotic yeast with enhanced lipid production and determining the lipid components have become the aim of the work.

STRESS, EMOTIONS, AND COPING: THE LIVED EXPERIENCES OF PRIMARY CAREGIVERS WHO RAISE ADOLESCENTS WITH BIPOLAR DISORDER

KIMBERLY MORTON CUTHRELL

Asian Journal of Advances in Medical Science, Volume 4, Issue 4, Page 19-32

The purpose of this phenomenological study was to examine the relationship between primary caregivers and their adolescents who have bipolar disorder and the caregivers’ coping and adapting skills in handling their adolescents’ behaviors. The caregivers’ perceptions of their coping and adapting skills were interpreted and analyzed through transcribing, coding, and mapping processes by using Creswell’s six-coding step strategy [1]. The data were analyzed using Blumer’s [2] symbolic interaction, and constructs from R. Lazarus’s [3] stress and emotion theory, Selye’s [4] stress theory, and R. Lazarus and Folkman’s [5] transactional model of stress and coping provided the foundation of this phenomenological study to explore the stress and emotions of the primary caregivers of adolescents with bipolar disorder. Sixteen caregivers from North Carolina were selected by purposive sampling (snowball sampling) to share their stories during semi-structured interviews. The results of this qualitative analysis were examined using a phenomenological approach that took advantage of narrative inquiry and symbolic interaction that looked for emergent themes. Primary thematic results indicated that the primary caregivers of adolescents with bipolar disorder encountered stress, physical alignments, and emotional problems that often led to damaged marriages; strained or broken family relations; employment problems; and negative associations with neighbors, law enforcement, social services, and the school system. An unexpected finding was that the men in the study who were caring for adolescents with bipolar disorder were more likely than women in similar circumstances to prefer physical methods such as jogging and walking as ways to reduce their stress. No other studies found this specific finding. Results will be used to enhancethe current literature by providingempirical insights that support the need for further research into bipolar disorder among adolescents.

Asian Journal of Advances in Medical Science, Volume 4, Issue 4, Page 33-41

Background: Following the success of the Lolli-Method or Lolli-Test as a surveillance method in Germany, the Ministry of Health, Singapore investigated the feasibility of deploying the method as a rostered routine testing in vulnerable individuals such as children, nursing homes and frontline workers; and evaluated the sensitivity and ideal pooling ratio of the Lolli-Method. 

Methods: The study was conducted in two phases – the first phase was to assess the operational feasibility of the Lolli-Method. It was held in conjunction with air sampling at a childcare centre with children ages 2 to 6 years old across 40 days. The second phase was to evaluate the sensitivity of the Lolli-Method with different pooling ratios and was conducted in collaboration with the National Centre for Infectious Diseases (NCID) where each pool was spiked with one Lolli swab from a COVID-positive patient. All patients enrolled in this study have their viral load cycle threshold (CT) levels assessed prior to admission via a mid-turbinate oropharyngeal (MTOP) polymerase chain reaction (PCR) swab. 

Results: The sensitivity of the pooled Lolli-Test was similar to antigen rapid tests with 100% sensitivity (3/3) in a pooling ratio of 20:1 for patients with viral loads of cycle threshold (CT) levels below 20. For individuals with lower viral loads, the sensitivity of the Lolli-Test was 66.7% (2/3) in a pooling ratio of 20:1 and 100% (2/2) in a smaller pooling ratio of 15:1. The operational feasibility of the Lolli-Test was assessed to be high amongst study participants although students were noted to require some additional assistance from teachers. 

Conclusion: The Lolli-Test is an effective surveillance method with adequate sensitivity to detect a COVID-19 infected individual in a pool of up to 20 albeit largely dependent on the viral load. Furthermore, the Lolli-Test also provides a less invasive alternative sample collection method for individuals who cannot tolerate or have contraindications for the regular nasal or oropharyngeal swabs such as young children. More studies should be done to assess the Lolli-Test’s true limit of detection and to evaluate the use of the Lolli-Method in infants and for other respiratory diseases such as influenza.

AHLAM ALNAQEB, ANAAM RUSTOM, ESRAA BARAKAT, YOUSRA FARE

Asian Journal of Advances in Medical Science, Volume 4, Issue 4, Page 42-53

Background: Road traffic injures is a significant public health issue which increase the global concern after being the tenth leading causes of death worldwide. The major victims from this issue are road users which include drivers, passengers, cyclists and pedestrians. According to Qatar National Road Safety Strategy, every year around 220 people lose their lives and a further 550 victims are seriously injured due to road traffic accidents (National Road Safety Strategy, 2013-2022). However, pedestrians’ fatal injuries constitute about twelve percent of the total death rate.

Objective: To investigate the health care resources and costs burden of pedestrian injuries from Road Traffic Accidents (RTAs) in Qatar during 2009 to 2011 and to estimate the injury severity score and mortality rates among these patients in order to provide evidence on the burden of managing pedestrians’ injuries in Qatar.

Methods: A retrospective cross sectional analysis of data collected from Hamad General Hospital trauma registry between January 2009 and December 2011. We used a cost model for various healthcare services used by the HMC Finance Department. Resource use and cost data are produced across various injury severity scores and years. Since this study is investigating and analyzing pedestrians’ injury resources and costs, the injury severity score is chosen as the main variable reflecting the total cost, length of stay (LOS) cost, intensive care unit (ICU) cost, ward unit cost, total procedure cost, total diagnostic cost, and blood unit cost. The frequency of sex, nationality 1 (Arab – Non-Arab – Qatari), nationality 2 (Nepal, India, Pakistan, Bangladesh, Philippines, and others), and year were analyzed. Data were analyzed using SPSS program.

Results: The discoveries of this report could be determined as the following; the majority of pedestrians’ injury was males and the highest rate of admission was in year 2011. It can be noticed that there are significant differences in diagnosis cost due to years with p-value <0.0001. The injury severity score had a strong relationship with the total cost, length of stay (LOS), total procedure cost, total diagnostic cost, and blood unit cost. Thus, there are significant differences between groups of total procedure cost, LOS cost, blood unit cost, and total cost due to ISS with p-value <0.0001. The injury severity score had a strong relationship with the total cost, length of stay (LOS), total procedure cost, total diagnostic cost, and blood unit cost.

Conclusion: This report offers evidence on healthcare resources and costs burden of pedestrians’ injuries over three years period in Qatar. It gives indication on how to better manage these patients in terms of healthcare resource allocations, and can be used in future planning by policy makers.

Asian Journal of Advances in Medical Science, Volume 4, Issue 4, Page 54-61

Trichomoniasis is a global public health problem affecting human genitals especially women with severe complications in pregnancy. It is poorly reported. A cross sectional survey of pregnant women in Aba North local council, Abia State southeast Nigeria was undertaken using specimen microscopy and structured questionnaire. Of 286 women investigated the overall prevalence of T. vaginalis alone in the population was 2.1%.  T. vaginalis disease proportion was associated with age (p < 0.05). Age range of 25-29 years had highest prevalence (4.8%) while 30-34 years had the least infection (1.05%). Pregnant mothers < 18 years and those within 35 years and above had no T. vaginalis infection. There was no association between trimester and disease proportion (p > 0.05). Of other STIs observed, Candida infection was highest (35.3%) while Chlamydia sp had the least prevalence (0.35%). Pregnant mothers within age of 25–29 years had more Candida infection (63.9%) than age group of 40 years and above. E. coli, Bacteria vaginosis, Staph aureus, and Chlamydia sp, had prevalences of 11.6%, 6.32%, 15.79%, and 1.05% respectively. Proportion of T. vaginalis, Candida, and E. coli infections in relation to age were statistically significant (p < 0.05). Proportions of observed STIs were significantly (p<0.05) associated with marital status. Candida sp and Staph aureus infections were more prevalent among traders and least among housewives. T. vaginalis and other STIs were not associated with level of education (p>0.05). There was significant (p<0.05) relationship between number of sex partners and sexually transmitted infections. Use of contraceptive such as condom was associated with proportion of infection (p < 0.05). T. vaginalis and other STIs are important public health threat in Aba hence routine screening and education of women about safe sex are highly recommended.

Asian Journal of Advances in Medical Science, Volume 4, Issue 4, Page 1-4

Background: Reporting a case of osteochondroma in an uncommon location in a pediatric patient.

Presentation of Case: A female patient with a history of limited pronation in the right forearm due to a solitary lesion in anterolateral part of distal third of the ulna, features suggesting ostechondroma both in imaging and histopathology.

Discussion: Distal ulnar exostosis are described in the literature in relation with multiple hereditary exostoses disease and deformities in ulna or both forearm bones requiring a surgical intervention but a solitary isolated forearm exostosis is rare.

Conclusion: Osteochondromas in the forearm are rare but they should be considered in the differential diagnosis if features are suggesting it.
