Understanding knowledge of hypertension among affected individuals in low-Income (B40) communities in Malaysia: The RESPOND study.

INTRODUCTION: Achieving optimal control of blood pressure is easier when those affected understand the risks and consequences of hypertension and the principles of management. It is particularly important in disadvantaged groups among whom blood pressure control is often poor. However, effective responses require evidence of the knowledge and beliefs of those affected. This was undertaken as part of a larger study of the therapeutic journeys followed by individuals living in B40 (bottom 40% by income) households in Malaysia, the Responsive and Equitable Health Systems-Partnership on Non- Communicable Diseases (RESPOND).This paper describes their reported knowledge of hypertension, health, and measures that can improve hypertensive control. MATERIALS AND METHODS: The communities were selected from rural and urban populations in four peninsular states (Selangor, Kelantan, Perak, and Johor). Following a multistage sampling approach, communities in each stratum were selected according to probability proportional to the size and identified based on national census data by the community and administrative registers. Households were randomly selected. Eligible individuals were those aged between 35 and 70 years old, self-reported or identified as hypertensive at screening. Informed consent was taken. A survey using validated questionnaires was conducted. RESULTS: The total number of respondents was 579. The mean age was 59.0 (95%: 58.4, 59.7) and more were women (71.5%) than men (28.5%). Regarding respondents selfreported level of hypertension knowledge, 2.9% reported having no knowledge at all, 80.1% had little knowledge, and 17.9% were very familiar. Among all respondents, 56.2% (95% CI: 50.7, 61.6) correctly answered at least four out of five objective knowledge questions.Almost all (91.5%) were aware that hypertension could cause a stroke. However, one-fifth believed it could cause cancer. Almost threequarters said that people with high blood pressure generally felt well (72.1%) and recognized that they should not stop taking their medication (70.7%). Most of the respondents knew that people should take their medication even if they feel well (73.6%). Although more than half (66.0%) of the respondents rated their health as poor. Interestingly, most did not perceive themselves as having a long-term illness (95.0%). CONCLUSION: This study provides reassurance that individuals with hypertension in disadvantaged communities in Malaysia have a relatively good understanding of hypertension. Further research should explore the challenges they face on their therapeutic journeys.

The household economic burden of non-communicable diseases in 18 countries

BACKGROUND: Non-communicable diseases (NCDs) are the leading cause of death globally. In 2014, the United Nations committed to reducing premature mortality from NCDs, including by reducing the burden of healthcare costs. Since 2014, the Prospective Urban and Rural Epidemiology (PURE) Study has been collecting health expenditure data from households with NCDs in 18 countries. METHODS: Using data from the PURE Study, we estimated risk of catastrophic health spending and impoverishment among households with at least one person with NCDs (cardiovascular disease, diabetes, kidney disease, cancer and respiratory diseases; n=17 435), with hypertension only (a leading risk factor for NCDs; n=11 831) or with neither (n=22 654) by country income group: high-income countries (Canada and Sweden), upper middle income countries (UMICs: Brazil, Chile, Malaysia, Poland, South Africa and Turkey), lower middle income countries (LMICs: the Philippines, Colombia, India, Iran and the Occupied Palestinian Territory) and low-income countries (LICs: Bangladesh, Pakistan, Zimbabwe and Tanzania) and China. RESULTS: The prevalence of catastrophic spending and impoverishment is highest among households with NCDs in LMICs and China. After adjusting for covariates that might drive health expenditure, the absolute risk of catastrophic spending is higher in households with NCDs compared with no NCDs in LMICs (risk difference=1.71%; 95% CI 0.75 to 2.67), UMICs (0.82%; 95% CI 0.37 to 1.27) and China (7.52%; 95% CI 5.88 to 9.16). A similar pattern is observed in UMICs and China for impoverishment. A high proportion of those with NCDs in LICs, especially women (38.7% compared with 12.6% in men), reported not taking medication due to costs. CONCLUSIONS: Our findings show that financial protection from healthcare costs for people with NCDs is inadequate, particularly in LMICs and China. While the burden of NCD care may appear greatest in LMICs and China, the burden in LICs may be masked by care foregone due to costs. The high proportion of women reporting foregone care due to cost may in part explain gender inequality in treatment of NCDs. (AU)

Substernal thoracoscopic guidance during sternal reentry.

Reentry sternotomy is commonplace, as more patients are returning for second, third, or more repeat cardiac procedures. Catastrophic hemorrhage remains the most dreaded complication during reentry and carries a significant morbidity and mortality. Although various methods are used to reduce the risk of hemorrhage, we have found that substernal thoracoscopy is preferable. Our experience with this technique in both adults and children is presented.

Cardiac pheochromocytoma: resection after diagnosis by 111-indium octreotide scan.

Cardiac pheochromocytoma is an exceedingly rare and unusual clinical entity. Only 37 previous surgically treated adult patients were found in review of the surgical literature. We report the case of a 13-year-old boy who had a cardiac pheochromocytoma that was localized by the 111-indium diethylenetriamine pentaacetic acid octreotide scintigraphy scan and confirmed by magnetic resonance imaging after computed tomographic and B1-iodine-metaiodobenzylguanidine scans had failed. At operation, a 6-cm pheochromocytoma of the left atrium was found and successfully resected with reconstruction of the left atrium using autologous pericardium.

Fragmentation of a Celestin tube causing intestinal obstruction. Case report and review of the literature.

Current management of benign and malignant esophageal lesions has changed little in the past 25 years. Treatment of unresectable lesions has consisted primarily of exclusion and bypass procedures as well as prosthetic intubations for relief of dysphagia. A case of a Celestin tube fragmentation in a patient with unresectable esophageal carcinoma causing small bowel obstruction is presented. Diagnosis, management, and review of the literature are discussed. Recommendations for use of the Celestin tube in patients with good long-term prognoses include keeping a high index of suspicion for possible complications, close and regular radiographic and endoscopic follow-up, and early surgical intervention upon tube fragmentation.

ICP changes following application of the MAST suit.

The MAST suit is used primarily in the field to raise arterial pressure in patients with hemorrhagic shock. By 'squeezing' blood back to the heart and compressing arteries, the suit acts to transfuse the patient as well as to compress bleeding sites. Because of the sudden increase in venous return with abdominal compression, its use has been questioned after closed head injury, cardiac tamponade, and/or tension pneumothorax. A study was devised to evaluate the MAST suit in dogs following hemorrhage and hemorrhage with the creation of a tension pneumothorax, cardiac tamponade, and mass intracranial lesion. Pulmonary artery, central venous, systemic arterial, and intracranial pressures were monitored in control dogs before and after hemorrhage and application of the MAST suit. Following hemorrhage, the inflated MAST suit raised systolic arterial pressure as well as central venous, pulmonary artery, and intracranial pressures. The rise in intracranial pressure mirrored the rise in venous pressure and never reached potentially harmful levels in the hemorrhaged animals and animals with a mass intracranial lesion. In the animals with cardiac tamponade and tension pneumothorax, inflation of the abdominal portion of the MAST suit produced a marked rise in central venous and intracranial pressures. This was altered by either relieving the lesion or reducing the pressure of the abdominal portion of the MAST suit.

Surgical treatment of infective valvular endocarditis.

Infective valvular endocarditis, whether occurring on a native or prosthetic heart valve, continues to carry a serious prognosis. Death is usually due to congestive heart failure, arrhythmia, or embolic complications, rather than infection per se. While antimicrobial therapy and medications to control congestive heart failure continue to be the treatment of choice in most cases, early valve replacement is indicated in certain situations. During the past four years, 12 patients underwent valve replacement for infective endocarditis. Six patients underwent elective valve replacement after antibiotic or antifugal therapy. All survived the operation and were improved. Six other patients underwent emergency valve replacement. Two patients died intraoperatively and their operations, in retrospect, were delayed unnecessarily. Four patients survived and are improved. Prosthetic valve replacement during the course of infective valvular endocarditis should be considered based on indications such as congestive heart failure, rhythm disturbances, etc, rather than the status of the infection.
