Hypertension prevalence and its trend in Bangladesh: evidence from a systematic review and meta-analysis.

BACKGROUND: Hypertension, itself being a major chronic condition, is one of the most significant risk factors for premature cardiovascular diseases and mortality. Hypertension is responsible for 13% of global deaths and three-quarters of the world's hypertensive population reside in low- and middle-income countries. Bangladesh is one of those countries that experiencing an epidemiological transition from communicable to non-communicable diseases, a nutritional transition from a traditional diet to process and fast food, and an increase in a sedentary lifestyle, resulting in increased hypertension prevalence. We carried out a systematic review and meta-analysis to identify existing research on hypertension prevalence in Bangladesh, summarize findings and assess its temporal change. METHODS: We searched MEDLINE, EMBASE and PubMed and relevant references to identify studies on the prevalence of hypertension in Bangladesh. We used Random-effects meta-analysis to pool the prevalence estimates and performed subgroup analyses. We assessed heterogeneity, a trend in prevalence of hypertension and publication bias in selected studies. RESULTS: Our search initially identified 735 articles and after removing duplicates, reviewing titles and abstracts, and screening full texts, 53 studies were finally selected. The studies comprised 305,432 subjects and reported overall, gender-specific, geographical location specific and criteria specific prevalence of hypertension. We identified the range of hypertension prevalence is from 1.10% to 75.0% and the overall weighted pooled prevalence of hypertension is 20.0%. An extremely high heterogeneity (I2 = 99.53%; Cochran Q-statistic p < 0.001) was observed in the prevalence of hypertension. Consequently, we performed subgroup analysis based on gender, age group and geographical location of the study participants, the cut-off level used to define hypertension, and the types of hypertension reported and presented our findings accordingly. An overall increasing trend of hypertension prevalence is also observed. CONCLUSIONS: The prevalence of hypertension is high and rising in Bangladesh. Strategies targeting prevention are required to mitigate a further increase in the prevalence and reduce the morbidity and mortality associated with it.

Health awareness, lifestyle and dietary behavior of university students in the northeast part of Bangladesh.

INTRODUCTION: University students generally face a variety of challenges. During this period of life, they practice some unhealthy eating patterns and lifestyles. Therefore, we aimed to assess the health awareness status of university students from the northeast part of Bangladesh and to evaluate its associated factors. METHODS: We conducted a cross-sectional study using a stratified random sampling among public and private university students from the northeast region of Bangladesh and interviewed 1143 students. We used a self-reported questionnaire, including questions related to awareness status, lifestyle practice, dietary habit and socio-demographic factors. To assess students' health awareness status and its association with their lifestyle practices and socio-demographic factors, we used logistic regression models. RESULTS: The majority (61%) of the students were not aware of better health status and their dietary habits were not adequate. Smokers [odds ratio (OR): 0.66; 95% confidence interval (CI): 0.44, 0.99] were less likely to be aware of better health status. The participants who thought that they were leading a healthy lifestyle were less likely (OR: 0.71; CI: 0.56, 0.92) to be aware. Moreover, frequency of participating in sports and the psychological factors related to eating behaviors were significantly (p < 0.05) associated with health awareness status. CONCLUSION: Our study findings may help to create a foundation for possible interventional programs on health awareness and nutritional education to improve the health awareness status and dietary behavior of university students. To prevent students from poor eating habits while feeling happy, effective programs (e.g. seminars, projects and media campaigns) should be held, which may include enhancing healthy and recommended amounts of food consumption.

Technetium-99m sestamibi scintimammography complements mammography in the detection of breast cancer.

Mammography remains the technique of choice for the detection of early breast cancer. The sensitivity of mammography is 85%, but is decreased in patients with dense breasts. Sestamibi scintimammography (SCM) has been suggested as an adjunctive modality to improve the detection of breast cancer. We conducted a study to determine the impact of SCM in patient management. A prospective study was conducted in 95 patients presenting with palpable masses and/or abnormal mammography scheduled for biopsy. Injection of 20-30 mCi of technetium-99m (Tc-99m) sestamibi into a pedal vein was performed. Ten-minute images of the breast and axilla were obtained in multiple projections. The mammography and SCM were correlated with pathology and clinical findings. The median age was 44 years (range 28-86 years). The total number of lesions was 104, as eight patients had bilateral lesions and one patient had two lesions in the same breast. Fifty-nine patients presented with palpable lesions and 45 patients with nonpalpable lesions (42 with abnormal mammography only and 3 with nipple discharge). A comparison of sensitivity, specificity, positive and negative predictive values, and overall accuracy of SCM and mammography were performed. The sensitivity and specificity for SCM were 83% and 83%, respectively, and for mammography were 65%, and 72%, respectively. The sensitivity and specificity for combined SCM and mammography were 87% and 94%, respectively. The p-value for mammography versus combined SCM and mammography was 0.0003 and that for SCM versus SCM and mammography was 0.0098. There were 80 (77%) benign and 24 (23%) malignant lesions. Of the 24 malignancies, SCM missed six (25%), versus eight (33%) by mammography. In two patients (9%) SCM detected malignancy in the breast that was not visualized by mammography or found on clinical examination. Sestamibi SCM improves the sensitivity of mammography and it detects up to 9% of malignancies not detected by mammography or clinical examination. This testing could impact the management of 16,500 patients in the United States every year. More studies are needed to better define its role in breast cancer detection.

A case report of recurrent epithelial ovarian cancer metastatic to the sternum, diaphragm, costae, and bowel managed by aggressive secondary cytoreductive surgery without postoperative chemotherapy.

BACKGROUND: Ovarian epithelial cancer typically presents in advanced stage and has been traditionally managed by a combination of cytoreductive surgery followed by adjuvant systematic chemotherapy. The management of recurrent ovarian cancer has been individualized: surgical resection of intraabdominal and/or pelvic disease has been performed when technically feasible and usually followed with chemotherapy. CASE: This case describes aggressive surgical management of recurrent ovarian cancer metastatic to the lower ribs, sternum, and diaphragm. A clear cell, Stage IIIA ovarian cancer was successfully resected in a 73-year-old female. The patient had total abdominal hysterectomy, bilateral salpingo-oophorectomy, and omentectomy followed by six cycles of adjuvant chemotherapy, consisting of cyclophospamide and carboplatinum. A period of 8 years elapsed before recurrent disease was detected; there were two separate metastatic sites. A secondary cytoreductive surgery without further chemotherapy has been the mainstay of treatment. A combination of exploratory laparotomy and en bloc resection revealed the metastatic deposits, a 5-cm mass involving the diaphragm, the lower aspect of the manubrium sternum, and four right lower ribs. The second deposit was identified in the left paracolic gutter invading the sigmoid colon. CONCLUSION: At 47 months of follow-up, the patient is alive and without any evidence of measurable disease by exam and confirmed by CT scans of chest, abdomen, and pelvis. To our knowledge, this is one of the few reported cases managed successfully by surgical approach and is recommended in selected patients with metastatic ovarian cancer.
