Knowledge, attitudes and practices of COVID-19 in rural Bangladesh: a cross-sectional study.

OBJECTIVES: Understanding the knowledge, attitudes and practices (KAP) of COVID-19 within distinct populations may aid further public health messaging. This study's aims were to explore KAP towards COVID-19 in rural Bangladesh and identify any potential links to sociodemographics, existing clinical conditions and sources of information. DESIGN: Cross-sectional community-based study. SETTING: Participants were recruited from 18 villages using multistage cluster random sampling. METHODS: Data were collected through face-to-face interviews, from June to November 2021, using a structured questionnaire. Data included sociodemographics, clinical conditions, sources of information and KAP of COVID-19 questions. Χ2 test, multiple logistic regression and correlation analyses were performed. RESULTS: A total of 1603 participants were included with mean ages of 42.3±14.2 years, ranging from 18 to 60 years. Of these, 51% were male, 42.2% had secondary education and 45% had comorbidities. Television was the main source of COVID-19 information (55.8%). The overall correct response rate of KAP questions was 90%, 78% and 59%, respectively. In stepwise multiple logistic regression, good knowledge was associated with higher education (adjusted OR (AOR): 4.61, 95% CI: 2.40 to 8.85, p<0.001), employment, high body mass index (overweight and obese) and trust in the sources of information. Being female (AOR: 1.48, 95% CI: 1.19 to 1.85, p<0.001), having depression (AOR: 1.80, 95% CI: 1.34 to 2.43, p<0.001), being a past smoker and sources of information (family members/friends/relatives/neighbours) were associated with positive attitudes. Good practices were associated with older age (AOR: 1.52, 95% CI: 1.10 to 2.11, p=0.01), higher education (AOR: 2.78, 95% CI: 1.58 to 4.89, p<0.001) and having anxiety, while current smokers and fully vaccinated people were less likely to be engaged in good practices. Positive significant correlations between domains of KAP were observed as well as between past vaccination KAP and COVID-19 KAP. CONCLUSION: This study uncovered gaps in understanding and practices, and identified targeted intervention especially for young and less educated people using mass media to promote updated knowledge regarding COVID-19 and the efficacy of preventive practices.

Retrospective comparison of ultrasound guided percutaneous and open skeletal muscle biopsies.

BACKGROUND: Open skeletal muscle biopsy has been the mainstay of sample retrieval in patients with suspected muscle diseases. However, this technique is limited by surgeon and theatre availability, potentially resulting in delayed diagnosis and increasing hospital stay. AIMS: To compare the effectiveness and timeliness of ultrasound guided 14-gauge needle percutaneous muscle biopsy in comparison with open biopsy. METHODS: We performed a retrospective chart review on 19 inpatients who underwent ultrasound-guided percutaneous muscle biopsy using a 14-gauge needle and 19 consecutive inpatients who underwent open surgical muscle biopsy between January 2017 and June 2019. Patient demographics, length of stay, biopsy sample size and the correlation between histological and clinical diagnosis were compared between groups. RESULTS: The median age of both groups was 64 years. Seventy-nine percent of surgical patients were female compared with 58% who had percutaneous biopsy. Surgical biopsies yielded larger samples (median 864 mm3 vs 17 mm3 , P = 0.03). While there was no difference in the length of inpatient stay (median 8 days), patients who had percutaneous biopsy had a shorter referral to procedure time (median 3 days vs 5 days, P = 0.012). Eighty-four percent of patients underwent MRI prior to percutaneous muscle biopsy, whereas only 16% had imaging before surgical biopsy (P ≤ 0.001). Most surgical biopsies were performed on the quadriceps whereas a wide range of muscles were sampled using the percutaneous technique. Overall, the percutaneous muscle sample was non-diagnostic in five cases (26%) despite a clinical diagnosis of myopathy. By comparison, two surgically obtained samples (11%) were non-diagnostic. CONCLUSION: Ultrasound guided percutaneous muscle biopsies were performed faster and a wider range of muscles were targeted. However, this technique yielded smaller samples, which were non-diagnostic in 26% of cases. Increasing the needle gauge or number of passes may improve the diagnostic yield of this technique.

Renal Disease Is Associated With Poor Outcomes Following Isolated Coronary Artery Bypass Grafting.

BACKGROUND: People with renal disease have a markedly higher risk of cardiovascular disease as well as morbidity and mortality after cardiac surgery. Little is known regarding the post-operative adverse outcomes following isolated coronary artery bypass graft (CABG) in the Australian population with renal disease. OBJECTIVES: The aim of this study was to examine the effect of different stages of renal disease on patients' risk of post-operative mortality and complications following isolated CABG in an Australian cohort. METHODS: Using the ANZSCTS (Australian and New Zealand Society of Cardiac and Thoracic Surgeons) registry, data from 44,968 patients who underwent isolated CABG between 2001 and 2014 were used. The effect of renal disease stages on short- and long-term outcomes were examined using multivariable logistic and Cox's regression methods respectively. RESULTS: Three of 4 Australian patients (74.6%) who underwent isolated CABG had some degree of renal disease: 50.2% mild; 20.9% moderate; 2.1% severe; and 1.6% dialysis-dependent. Adjusted risk of 30-day mortality increased with deteriorating renal disease from mild (1.6-fold) to dialysis-dependent (4.6-fold). Worsening renal disease was also associated with higher risk of post-operative complications. Hazard ratio for long-term survival shows steady increase of mortality risk with worsening renal disease categories from 1.1-fold for mild to 3.9-fold for patients on dialysis. CONCLUSIONS: Pre-existing renal disease is significantly associated with 30-day and long-term mortality, length of intensive care unit and hospital stay as well as several other post-operative complications.

Burden of macro- and micro-vascular complications of type 2 diabetes in Bangladesh.

OBJECTIVE: The aim was to estimate the burden of macro- and micro-vascular complications on hospitalisation and healthcare cost among people with type 2 diabetes mellitus in Bangladesh. METHODS: A cross-sectional study was carried out in 2017. A total of 1253 patients were recruited from six hospitals. Information related to cost and complications of type 2 diabetes were collected. Multiple logistic and non-parametric regression analyses were performed to evaluate the effect of complications on hospitalisation and average annual cost. RESULTS: Overall, 63.4% of the participants had complications of which 14.8% and 20.7% had macro- and micro-vascular complications respectively and 27.9% had both. Use of insulin, presence of both hypertension and dyslipidaemia, coronary artery diseases, stroke, nephropathy, and retinopathy were significantly associated with hospitalisation. Further, use of oral hypoglycaemic agent with a combination of insulin, presence of coronary artery diseases, stroke, nephropathy, and retinopathy increased the average annual cost. CONCLUSION: The prevalence of macro- and micro-vascular complications were very high in Bangladesh and majority of them are key drivers for hospitalisation and increased healthcare cost. An improvement of primary prevention strategy for complications is urgently needed which in turn will reduce the long-term healthcare cost for type 2 diabetes in Bangladesh.

Cost-of-illness of type 2 diabetes mellitus in low and lower-middle income countries: a systematic review.

BACKGROUND: Diabetes is one of the world's most prevalent and serious non-communicable diseases (NCDs). It is a leading cause of death, disability and financial loss; moreover, it is identified as a major threat to global development. The chronic nature of diabetes and its related complications make it a costly disease. Estimating the total cost of an illness is a useful aid to national and international health policy decision making. The aim of this systematic review is to summarise the impact of the cost-of-illness of type 2 diabetes mellitus in low and lower-middle income countries, and to identify methodological gaps in measuring the cost-of-illness of type 2 diabetes mellitus. METHODS: This systematic review considers studies that reported the cost-of-illness of type 2 diabetes in subjects aged 18 years and above in low and lower-middle income countries. The search engines MEDLINE, EMBASE, CINAHL, PSYCINFO and COCHRANE were used form date of their inception to September 2018. Two authors independently identified the eligible studies. Costs reported in the included studies were converted to US dollars in relation to the dates mentioned in the studies. RESULTS: The systematic search identified eight eligible studies conducted in low and lower-middle income countries. There was a considerable variation in the costs and method used in these studies. The annual average cost (both direct and indirect) per person for treating type 2 diabetes mellitus ranged from USD29.91 to USD237.38, direct costs ranged from USD106.53 to USD293.79, and indirect costs ranged from USD1.92 to USD73.4 per person per year. Hospitalization cost was the major contributor of direct costs followed by drug costs. CONCLUSION: Type 2 diabetes mellitus imposes a considerable economic burden which most directly affects the patients in low and lower-middle income countries. There is enormous scope for adding research-based evidence that is methodologically sound to gain a more accurate estimation of cost and to facilitate comparison between studies.

Barriers to Cervical Cancer and Breast Cancer Screening Uptake in Low-Income and Middle-Income Countries: A Systematic Review

Background: Cervical cancer (CCa) and breast cancer (BCa) are the two leading cancers in women worldwide. Early detection and education to promote early diagnosis and screening of CCa and BCa greatly increases the chances for successful treatment and survival. Screening uptake for CCa and BCa in low and middle - income countries (LMICs) is low, and is consequently failing to prevent these diseases. We conducted a systematic review to identify the key barriers to CCa and BCa screening in women in LMICs. Methods: We performed a systematic literature search using Ovid MEDLINE, EMBASE, PsycINFO, SCOPUS, CINHAL Plus, and Google scholar to retrieve all English language studies from inception to 2015. This review was done in accordance with the PRISMA-P guidelines. Results: 53 eligible studies, 31 CCa screening studies and 22 BCa screening studies, provided information on 81,210 participants. We found fewer studies in low-income and lower - middle - income countries than in upper - middle - income countries. Lack of knowledge about CCa and BCa, and understanding of the role of screening were the key barriers to CCa and BCa screening in LMICs. Factors that are opportunities for knowledge acquisition, such as level of education, urban living, employment outside the home, facilitated CCa and BCa screening uptake in women in LMICs. Conclusions: Improvements to CCa and BCa screening uptake in LMICs must be accompanied by educational interventions which aim to improve knowledge and understanding of CCa and BCa and screening to asymptomatic women. It is imperative for governments and health policy makers in LMICs to implement screening programmes, including educational interventions, to ensure the prevention and early detection of women with CCa and BCa. These programmes and policies will be an integral part of a comprehensive population-based CCa and BCa control framework in LMICs.

Sharing sensitive health information through social media in the Arab world.

BACKGROUND: Sharing daily activities on social media has become a part of our lifestyle, but little is known about sharing sensitive health information in the Arab world. OBJECTIVE: The objective of this study is to explore how social media users in the Arab world share sensitive health information through Facebook. DESIGN: A retrospective qualitative analysis was used in the study. SETTINGS AND PARTICIPANTS: A total of 110 Facebook groups, related to HIV, sickle cell and depression were screened between 5 June and 1 December 2014. RESULTS: Forty four Facebook groups met the inclusion criteria. 28 471 posts were extracted, of which 649 met inclusion criteria. Forty two percent of health information exchanged were related to HIV, 34% to depression and 24% to sickle cell diseases. The majority of postings were from Egypt 21.1%, Saudi Arabia 20%, Algeria 10% and Libya 9.2%. Male posts were 54.2% while 45.8% were posted by females. Individuals utilized Facebook groups to share personal experiences of their disease 31%, in addition to being used for seeking queries 13.6%, offering explicit advice 8.3%, reporting signs and symptoms of the disease 7.3% and posting their communication with the health-care provider 6.6%. CONCLUSIONS: Users in the Arab world use social media to exchange sensitive health information, which could have serious implications regarding the privacy of the information shared with other members of the group. On the other hand, sharing health information could have positive effects for patients, such as sharing disease experiences and peer support. However, more work is needed to ensure that Facebook users in the Arab world are aware of the potential consequences of sharing sensitive health information through social media.
