Assessment of descending aortic blood flow velocities with continuous wave Doppler echocardiography among healthy Children in South East Nigeria

2024-03-13T10:31:00+00:00

Background
The descending aorta velocity is important predictor of aortic disease in children and can be very helpful in some clinical and surgical decision making.
Aim
The purpose of this study is to assess the normative values of descending aorta velocity among children from South-East Nigeria. It also aimed to assess the correlation between age, body surface area and mean velocity across the descending aorta.
Methods
This is a cross-sectional study where the descending aorta velocity of one hundred and eleven children were enrolled consecutively using digitized two-dimensional and Doppler echocardiography.
Results
A total of 111 children had echocardiography to study their cardiac structures and compute their mean scores of their descending aorta velocity. The mean velocity across the descending aorta was 1.3±0.2m/s with maximum and minimum velocities of 2.06 and 0.84cm respectively. The mean descending aorta velocity in males (1.37±0.24 m/s) was significantly higher than that in females (1.24±0.18); (Student T test 3.09, p = 0.03). There was no correlation between age and mean velocity across the descending aorta (Pearson correlation coefficient; -0.03, p = 0.7) nor between body surface area and descending aorta velocity (correlation coefficient 0.01, p= 0.8).
Conclusions
The presented normalized values of the descending aorta velocity using a digitized two-dimensional and Doppler echocardiography among healthy children will serve as a reference values for further studies and can be applied for clinical and surgical use in children with various cardiac anomalies.

Comparing motor development in children with hydrocephalus after treatment with ventriculoperitoneal shunt and endoscopic third ventriculostomy: a cross-sectional study

2024-03-13T10:41:35+00:00

Introduction
Ventriculoperitoneal shunt insertion (VPSI) and endoscopic third ventriculostomy (ETV) are the major procedures for treating pediatric hydrocephalus. However, studies comparing motor development following the two treatments are limited.
Objective
We aimed to determine motor development outcomes in children with hydrocephalus up to 2 years of age after undergoing VPSI or ETV, to identify which surgical approach yields better motor outcomes and may be more effective for Malawian children.
Methods
This was a cross-sectional study where we recruited two groups of participants: one group consisted of children with hydrocephalus treated with VP shunt whilst the other group were treated with ETV, at least 6 months prior to this study. Participants were identified from the hospital records and were called to come for neurodevelopmental assessment using the Malawi Development Assessment Tool (MDAT).
Results
A total 152 children treated for hydrocephalus within an 18-month period met the inclusion criteria. Upon follow up and tracing, we recruited 25 children who had been treated: 12 had VPSI and 13 had ETV. MDAT revealed delays in both assessed motor domains: 19 out of the 25 children had delayed gross motor whilst 16 of 25 had delayed fine motor development. There was no significant difference between the shunted and the ETV groups.
Conclusion
Children with hydrocephalus demonstrate delays in motor development six to 18 months after treatment with either VPSI or ETV. This may necessitate early and prolonged intensive rehabilitation to restore motor function after surgery. Long-term follow-up studies with bigger sample sizes are required to detect the effect of the two treatment approaches.

Consumption and adverse reaction reporting of herbal medicines among people living with HIV at University teaching hospitals in Blantyre, Malawi and Ibadan, Nigeria

2024-03-13T10:53:50+00:00

Background
Consumption of herbal medicines among people living with HIV is a common practice in Sub-Saharan Africa. The utilization of herbal medicines was at 17.5% and 67.9% in Malawi and Nigeria, respectively. There is inadequate data on use and adverse reactions (ADRs) reporting of herbal medicines among people living with HIV (PLWHIV). This study was designed to investigate use and ADRs reporting of herbal medicines among PLWHIV at the University Teaching Hospitals in Blantyre, Malawi and Ibadan, Nigeria.
Methodology
A cross-sectional study was conducted among PLWHIV attending Antiretroviral Therapy (ART) clinic at Queen Elizabeth Central Hospital, Blantyre, Malawi and University College Hospital, Ibadan, Nigeria. A structured questionnaire was administered to 360 and 370 participants in Blantyre and Ibadan respectively, through face-to-face interviews after obtaining their informed consent.
Results
The prevalence of herbal medicines use among PLWHIV in Malawi and Nigeria was at 80.6% and 55.7% (p<0.001), respectively. The most frequently used herbal medicines in Malawi were Aloe vera (14.0%), Moringa oleifera (14.0%), Zingiber officinale (13.0%) and Allium sativum (7.0%). Likewise, in Nigeria, the most commonly used herbal medicines were Zingiber officinale (15.0%), Vernonia amygdalina (14.0%), Moringa oleifera (9.0%), and Allium sativum (11.0%). The major reason for herbal medicines’ use in Malawi was ready availability (42.1%) and perception that it boosts immunity (44.6%) in Nigeria. The PLWHIV reported experiencing suspected herbal medicine ADRs in Malawi (3.9%) and in Nigeria (8.0%).
Conclusion
A higher percentage of people living with HIV are using herbal medicines in Malawi as well as in Nigeria. In both countries, a few participants reported experiencing suspected ADRs related to herbal medicines.

Utilisation of standardised outcomes measures by clinical Physiotherapists working in Namibia: a nationwide cross-sectional study

2024-03-13T11:14:07+00:00

Introduction
The utilisation of standardised outcome measures (SOMs) is crucial for evaluating patients’ health status. Physiotherapists are highly recommended to use SOMs routinely. Despite the well-documented benefits of using SOMs, the utilisation of SOMs in clinical practice is still problematic particularly in Africa. In Namibia, there is dearth of information about SOMs utilisation by physiotherapists and the associated factors. This study was aimed at determining the extent of routine utilisation of SOMs and the associated demographic and work-related factors among physiotherapists.
Methods
A cross-sectional, nationwide, online survey was conducted and all registered qualified physiotherapists and intern physiotherapists working in public or private hospitals/clinics were invited to participate. Data was analysed using Statistical Package for the Social Sciences (SPSS) version 29.0. The Chi-square (χ2) and Fishers exact test investigated the relationship between the associated factors and routine SOMs utilisation. The alpha level was set at 0.05.
Results
Of 230 participants who received the invitational link, 99 (43.0%) responded timeously to the call to participate. Although 97.9% (n=94) of the participants indicated having used at least one type of SOMs in the last six months, the frequency of utilisation varied. Routine utilisation, defined as 70%-100% of the time, was reported in only 49.0% of the participants. The Chi-square test only showed significant findings for gender (p=0.01) and clinical specialty (p=0.004). The odds of utilising SOMs were 4.13 greater among physiotherapists with a clinical specialty and 3.88 times greater for females than males.
Conclusion
The rates for routine utilisation of SOMs by Namibian physiotherapists are unfavourable. Female gender and clinical specialty influenced the utilisation of SOMs in daily clinical practice. Cognisant of the study limitations, these results call for the need to improve the routine utilisation of the SOMs in Namibia.

The Interest in Betting, Smoking, Alcohol, and Drugs in Malawi: Changing Trends between 2012-2022

2024-03-13T11:22:58+00:00

Background
In recent years, the online gambling market has rapidly developed, and betting has become one of the most popular forms of gambling. The aim of this study was to analyse the interest of the Malawian population in terms related to betting, sports betting, alcohol, cigarettes, and some psychoactive drugs through the relative search volumes of Google Trends.
Methods
Internet search query data related to betting, sports betting, alcohol, cigarettes, and psychoactive drugs were obtained monthly from Google Trends for the period 2010-2022. Comparisons of interest levels in these topics were conducted in Malawi, and correlation coefficients were calculated.
Results
In Malawi, relative search volumes for betting and sports betting terms were the highest (average RSVs: 66% and 30%). It was found that from 2019 onwards, the interest in betting and sports-related search topics and keywords increased significantly (p < 0.001). Strong positive correlations were found between betting-related keywords and alcohol and gross domestic product (r = 0.831 and r = 0.901, p < 0.001). A positive correlation was found between betting and psychoactive drug-related terms (minimum r = 0.417, p < 0.01).
Conclusions
This study concludes that the interest of the Malawian population in betting has increased in recent years, while interest in psychoactive drugs and alcohol remains high. Gross domestic product is highly correlated with society’s interest in betting. It was additionally found that Google Trends can be used as a tool to predict and monitor future risky behaviours, such as gambling disorder.

Clinical features and Surgical Outcomes of Thyroid Goitre Presenting to Ear, Nose and Throat Department of Queen Elizabeth Central Hospital, Blantyre, Malawi

2024-03-13T12:26:44+00:00

Introduction
In Malawi there is a perception that goitre is common and causes significant public health and economic burdens. The purpose of this study was to assess the demographic distribution, clinical presentation, investigations, management, outcomes and complications of goitre seen at Queen Elizabeth Central Hospital (QECH), Blantyre, Malawi.
Method
A single hospital-based descriptive retrospective study from January 2017 to December 2018 for all patients presenting with goitre.
Results
Out of 9073 patients who presented to ENT department, 105 patients presented with goitre representing 1% of all patients seen during the study period. The Male: Female ratio was 1:25. The mean symptom duration with goitre was 4 years (SD +/- 6.4). Thyroid function test results were available in 54 patients and out of these, 53(98%) patients were euthyroid. Ultrasound scan (USS) reports were available in 44 patients, of these 32(73%) were multinodular goitres. In 70 cases, pathology results were available and showed that 20% were thyroid cancers and that papillary thyroid carcinoma was the commonest cancer (64%).Two recurrent laryngeal nerve injuries were recorded in 79 surgical procedures representing 2.5% of patients (6.3% overall complication rate). Inpatient stay ranged from 2 days to 49 days (median 3 days).
Conclusion
Goitre at our centre is more common in women than in men. One in five patients in this cohort had thyroid cancers. This prevalence is higher than other areas in the world highlighting the need for cytology services on every patient before surgery and histology services after surgery. Recurrent laryngeal nerve injury and other complications were infrequent demonstrating local high safety of thyroid surgery, despite late presentation to the ENT department.

Comparison of two different Nasal Interfaces used in Non-Invasive Respiratory support in terms of Neonate comfort

2024-03-13T11:37:54+00:00

Background
Non-Invasive Ventilation (NIV) is the first choice approach in neonates with sufficient respiratory effort that require respiratory support. The type of nasal interface used in NIV affects both efficacy and patient comfort. The aim of this study is to investigate the effects of different nasal interfaces used in NIV support on neonatal patient comfort.
Methods
Our study evaluated patients who received NIV support for 24 hours. The patients were randomly divided into two groups according to the type of nasal interface used, which were RAM cannula and short binasal prong (SBP). The patients’ demographic and clinical data were noted. Their sleep was monitored for 24 hours with an actigraphy device.
Results
A total of 82 patients were evaluated. The sleep efficiency in the RAM cannula group was significantly higher (respectively, 65.7% [10.22-95.25] vs. 57.81% [2.49-77], p=0.004). Although not statistically significant, the neonates in the RAM cannula group exhibited longer total sleep time (respectively, 10.4 ± 4.28 hours vs. 9.02 ± 3.73 hours, p=0.161). Comparison of heart rates and respiratory rates indicate that the patients in the RAM cannula group were more comfortable.
Conclusions
Our study found that infants who received NIV support through a RAM cannula experienced more efficient sleep. Holistic approaches in neonatal intensive care units are vital for better neurodevelopmental outcomes in newborns. Although non-invasive, the interface used in NIV should also be a part of this holistic approach.

Evaluation of the relationship between Knee Osteoarthritis and Meniscus Pathologies

2024-03-13T11:51:46+00:00

Background
Knee osteoarthritis is a common, degenerative joint disease that causes chronic pain that affects daily life. Our study aims to evaluate geriatric patients aged 65 and over with knee pain in terms of osteoarthritis with radiography and magnetic resonance imaging and to investigate its relationship with meniscal pathologies.
Methods
Radiography and magnetic resonance imaging of patients aged 65-88 years with knee pain were evaluated in terms of knee osteoarthritis and staging was performed. Meniscal pathologies were evaluated in magnetic resonance imaging, and the prevalence of different meniscal lesion types was calculated. In addition, the relationship between knee osteoarthritis and meniscal pathologies was analyzed.
Results
Radiographic evidence of knee osteoarthritis was found in 182 (84.2%) of the 216 cases in our study group. A strong correlation was found between the degrees of knee osteoarthritis on magnetic resonance imaging and radiography. At least one meniscus pathology was observed in all 182 radiography cases with knee osteoarthritis findings. At least one meniscus pathology was observed in 29 (85.3%) of those without osteoarthritis signs. It was determined that meniscus degeneration, tear, and extrusion were observed more frequently in patients with knee osteoarthritis than in patients without osteoarthritis. Meniscal extrusion and complex and horizontal-type tears were the most common lesions.
Conclusions
Osteoarthritis was found to be common in geriatric patients with knee pain. A correlation was found between radiography and magnetic resonance imaging regarding knee osteoarthritis. It was observed that meniscal pathologies were detected more frequently in patients with knee osteoarthritis.

Awareness of urinary incontinence in pregnant women as a neglected issue: a cross-sectional study

2024-03-13T11:58:49+00:00

Background
Pregnancy and labor are independent risk factors for the development of urinary incontinence (UI). Although UI is common during pregnancy, it is a health problem mostly neglected by pregnant women. The high prevalence of UI in pregnancy and its effects on the postpartum period justifies the need to determine the knowledge and attitudes of pregnant women regarding the prevention and management of UI. It is necessary to increase the awareness of pregnant women about UI, educate, consultant, and integrate pelvic floor muscle training into prenatal care services. This study aims to determine the UI awareness of pregnant women and their knowledge and attitudes in this context.
Methods
This cross-sectional study was conducted with 255 pregnant women in a university hospital in Turkey between March and September 2020. Data were collected using the Incontinence Knowledge Questionnaire (PIKQ) and Urinary Incontinence Attitude Scale (UIAS).
Results
The UI prevalence was 51% during pregnancy. The mean score of PIKQ was 8.07±2.64, and only 6.3% of participants correctly answered all the questions regarding UI. The mean score of UIAS was 42.33±3.48. A positive correlation was found between UI knowledge and attitude score (r=0.35, p=0.00).
Conclusions
The results showed that although UI is prevalent during pregnancy, pregnant women’s knowledge of UI is poor. Nearly half of pregnant women need information. They tend to display positive attitudes towards UI, but not sufficient to improve their health-seeking behavior. Strategies should be developed to increase pregnant women’s awareness of UI and to encourage them health-seeking behaviors for the prevention/management of UI during prenatal visits.

A special case of acute portal vein thrombosis

2024-03-13T12:05:43+00:00

Among the risk factors and underlying etiology of acute portal vein thrombosis, viral hepatitis is an extremely rare cause. We report a case of a young healthy 40-year-old male who was diagnosed with acute hepatitis A virus infection and presented with acute portal vein thrombosis. This article describes the possible pathophysiological mechanisms, clinical symptoms, and treatment of acute portal vein thrombosis in this patient. Based on this patient’s history and treatment, we encourage testing for hepatitis A serological markers in the emergency department in a population with recent hepatitis A exposure risk factors and concurrent unexplained acute portal thrombosis.
