The burden of type 2 diabetes in Australia during the period 1990-2019: Findings from the global burden of disease study

AIMS

To describe morbidity and mortality trends of type 2 diabetes in Australia, from 1990 to 2019, compared with similar sociodemographic index (SDI) countries.

METHODS

Australia-specific Global Burden of Diseases data were used to estimate age-standardised, age-specific, and sex-specific rates for prevalence, years lived with disability (YLDs), years of life lost (YLLs), disability-adjusted life years (DALYs), and deaths due to type 2 diabetes between 1990 and 2019. Australian data were compared with 14 similar SDI countries.

RESULTS

Type 2 diabetes increased in Australia between 1990 and 2019. The age-standardised prevalence increased from 1,985 [95% Confidence Interval (CI): 1,786.7-2195.3] per 100,000 population, to 3,429 [95% CI 3,053.3-3,853.7]. Cases tripled, from 379,532 [342,465-419,475] to 1,307,261 [1,165,522-1,461,180]. The age-standardised death rates doubled, from 2,098 [1,953-2,203] per 100,000, to 4,122 [3,617-4,512]. DALYs doubled, from 70,348 [59,187-83,500] to 169,763 [129,792-216,150], with increases seen in YLDs and YLLs. Men displayed higher rates. Compared to similar SDI countries, Australia ranked 4th in terms of burden for type 2 diabetes.

CONCLUSIONS

The burden of type 2 diabetes in Australia has increased considerably over three decades. There is an urgent need to prioritise resource allocation for prevention programs, screening initiatives to facilitate early detection, and effective and accessible management strategies for the large proportion of the population impacted by type 2 diabetes.

Now you see it! Using wearable cameras to gain insights into the lived experience of cardiovascular conditions

Wearable cameras offer an innovative way to discover new insights into the lived experience of people with cardiovascular conditions. Wearable cameras can be used alone or supplement more traditional research methods, such as interviews and participant observations. This paper provides an overview of the benefits of using wearable cameras for data collection and outlines some key considerations for researchers and clinicians interested in this method. We provide a case study describing a study design using wearable cameras and how the data were used.

Wearable cuffless blood pressure monitoring devices: a systematic review and meta-analysis

Aims

High blood pressure (BP) is the commonest modifiable cardiovascular risk factor, yet its monitoring remains problematic. Wearable cuffless BP devices offer potential solutions; however, little is known about their validity and utility. We aimed to systematically review the validity, features and clinical use of wearable cuffless BP devices.

Methods and results

We searched MEDLINE, Embase, IEEE Xplore and the Cochrane Database till December 2019 for studies that reported validating cuffless BP devices. We extracted information about study characteristics, device features, validation processes, and clinical applications. Devices were classified according to their functions and features. We defined devices with a mean systolic BP (SBP) and diastolic BP (DBP) biases of <5 mmHg as valid as a consensus. Our definition of validity did not include assessment of device measurement precision, which is assessed by standard deviation of the mean difference-a critical component of ISO protocol validation criteria. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies version 2 tool. A random-effects model meta-analysis was performed to summarise the mean biases for SBP and DBP across studies. Of the 430 studies identified, 16 studies (15 devices, 974 participants) were selected. The majority of devices (81.3%) used photoplethysmography to estimate BP against a reference device; other technologies included tonometry, auscultation and electrocardiogram. In addition to BP and heart rate, some devices also measured night-time BP (n = 5), sleep monitoring (n = 3), oxygen saturation (n = 3), temperature (n = 2) and electrocardiogram (n = 3). Eight devices showed mean biases of <5 mmHg for SBP and DBP compared with a reference device and three devices were commercially available. The meta-analysis showed no statistically significant differences between the wearable and reference devices for SBP (pooled mean difference = 3.42 mmHg, 95% CI: -2.17, 9.01, I² 95.4%) and DBP (pooled mean = 1.16 mmHg, 95% CI: -1.26, 3.58, I² 87.1%).

Conclusion

Several cuffless BP devices are currently available using different technologies, offering the potential for continuous BP monitoring. The variation in standards and validation protocols limited the comparability of findings across studies and the identification of the most accurate device. Challenges such as validation using standard protocols and in real-life settings must be overcome before they can be recommended for uptake into clinical practice.

The Use and Perceived Barriers of the Partograph at Public Health Institutions in East Gojjam Zone, Northwest Ethiopia

Introduction:

The partograph is a vital tool used to reduce maternal and fetal mortality and morbidity and to prevent prolonged and obstructed labor, as well as postpartum hemorrhage and fistula formation. This study explored the use and barriers of the partograph among obstetric caregivers in East Gojam Zone, Northwest Ethiopia.

Methods and materials:

A cross-sectional study design consisting of both quantitative and qualitative methods was utilized. Data was collected through a structured clinical observation checklist and semistructured questions. The content of the checklists was developed according to modified WHO partograph. Thematic analysis was employed using open code software version 3.6. Coding was done immediately after the data was collected. The coded data was defined and categorized into groups. Once the categories were identified and the names given, the data was related to the objectives of the study. Data was crosschecked to ensure consistency between the themes and the categories. Then we summarized the themes and drew conclusions that gave answers to the research questions.

Results and conclusion:

This study showed that participants believed partograph is an essential tool used to reduce maternal and fetal mortality and morbidity and to prevent prolonged and obstructed labor, as well as postpartum hemorrhage. They explained that work overload, lack of skill and competency, negligence, lack of motivation and a shortage of infrastructure and resources hindered utilization of the partograph.

Childhood behavioural disorders in Ambo district, western Ethiopia. II. Validation of the RQC

We report here on a study conducted to measure the validity of an Amharic version of the Reporting Questionnaire for Children (RQC), that was used in a survey of childhood behavioural disorders in a predominantly rural district in western Ethiopia. Mothers of 196 children aged 5-15 years, who were initially interviewed by the RQC were re-interviewed by a psychiatrist who was unaware of the RQC status of these children. The re-interview was conducted using a DSM IV checklist. The study showed that a cut-off point of one or more positive responses to any of the 10 questions on the RQC maximized sensitivity (87.5%) and specificity (65%). The discriminatory power of each item was also computed, and the item dealing with wetting/soiling oneself was found to have the highest ability to identify cases from non-cases. The item on abnormal speech was found to have the least discriminating power.

Childhood behavioural disorders in Ambo district, western Ethiopia. I. Prevalence estimates

The study was conducted between September 1994 and May 1995 in Ambo district, western Ethiopia. The prevalence of childhood behavioural disorder in children was found to be 17.7%. Behavioural disorder was found to be more common in boys than in girls. The prevalence increased with age. The most frequent symptoms reported were headache and nervousness. The least prevalent symptom was stealing things from home. As age increased, the risk of behavioural disorder increased. The increase in risk was statistically significant in the 15-year-old group when compared to the age group 5-7 years (adjusted Odds Ratio, OR = 1.89, 95% confidence interval, CI: 1.08-2.85). Childhood mental disorder was statistically significantly associated with parental age and with parental marital status. Children whose parents were < or = 24 years old had a higher risk of having mental disorders (OR: 2.03, 95% CI: 1.30-3.16) compared to those children whose parents were in the 45+ age group. Children whose parents were categorized as unmarried, divorced, separated, or widowed had a higher risk of having behavioural disorders (OR: 2.22, 95% CI: 1.70-2.91) than children whose parents were married. There was a statistically significant association between parental psychoneurosis and children's behavioural disorders; children whose mothers had psychoneuroses were at a higher risk of having behavioural disorders as compared to those whose mothers had no psychoneurosis (OR: 1.78, 95% CI: 1.34-2.35).

[Hysterical syndromes in a population of ambulatory neuropsychiatric patients in northwest Ethiopia. Phenomenology, psychosocial and sociocultural background]

Among 1240 first-time patients in the out-patient department of Gondar College of Medicas Sciences during the period September 1985-Juli 1986, there was, be European standards, an astonishingly high percentage of hysterical symptoms: 12.5% of all cases, 33.5% of all neurotic cases, with markedly "classic" symptomatology. These hysterical behavior patterns were interpreted as being, in the main, special problem solution mechanisms with secondary acquisition of illness under rapidly changing social conditions.

[The status of epileptic patients in a developing African country: northwest Ethiopia]

Of 1240 first-time consultations in the neuropsychiatric clinic of the Gondar College of Medical Sciences in an eleven-month period during 1985 and 1986, 152 patients came seeking relief from seizures. This paper deals with the origins and background of diagnostic, differential diagnostic, and therapeutic problems, and with problems of social rehabilitation. While in such a tradition-bound society certain hypotheses continue to have an unfavorable effect, there are unmistakable signs of positive change against a background of rapid social change. Conclusions are drawn for the better management of epileptic patients in developing countries.

[Description of an ambulatory neuropsychiatric patient population in the Gondar region, Northwest Ethiopia: epidemiologic and clinical aspects]

The paper deals with the morbidity profile of 1240 patients in the neuropsychiatric outpatient department of the Gondar College of Medical Sciences in the course of eleven months in the years 1985-1986, and proceeds to compare in with a previous analysis, that of Bach and Bachmann (1987). Although the morbidity profile tallies remarkably well with that in Central Europe, the extensive practice of consulting traditional healers disguises the exact situation. Constantly shifting regional peculiarities has a great influence on the morbidity of individual clinical pictures. Epidemiological and clinical aspects are discussed in the context of the relevant African literature.
