ABSTRACT

Sacha Inchi (Plukenetia volubilis L.) is a plant native in the Amazon rainforest in South America known for its edible seeds, which are rich in lipids, proteins, vitamin E, polyphenols, minerals, and amino acids. Rural communities in developing nations have been using this plant for its health benefits, including as a topical cream for rejuvenating and revitalising skin and as a treatment for muscle pain and rheumatism. Although Sacha Inchi oil has been applied topically to soften skin, treat skin diseases, and heal wounds, its protein-rich seeds have not yet received proper attention for extensive investigation. Proteins in Sacha Inchi seeds are generally known to have antioxidant and antifungal activities and are extensively used nowadays in making protein-rich food alternatives worldwide. Notably, large-scale use of seed proteins has begun in nanoparticle and biofusion technologies related to the human health-benefitting sector. To extract and identify their proteins, the current study examined Sacha Inchi seeds collected from the Malaysian state of Kedah. Our analysis revealed a protein concentration of 73.8 ± 0.002 mg/g of freeze-dried seed flour. Employing liquid chromatography-tandem mass spectrometry (LC-MS/MS) and PEAKS studio analysis, we identified 217 proteins in the seed extract, including 152 with known proteins and 65 unknown proteins. This study marks a significant step towards comprehensively investigating the protein composition of Sacha Inchi seeds and elucidating their potential applications in the food and biopharmaceutical sectors. Our discoveries not only enhance our knowledge of Sacha Inchi's nutritional characteristics but also pave the way for prospective research and innovative advancements in the realms of functional food and health-related domains.

ABSTRACT

BACKGROUND: In Bangladesh, cervical cancer (CC) is the 2nd most common cancer with estimated 8068 new cases and 5,214 deaths every year. It is also revealed that different socio-demographic factors have association with CC. This study was performed to evaluate the colposcopy outcomes and the association of different demographic and reproductive risk factors with cervical pre-cancer and cancer. METHODS: This retrospective cross-sectional study was carried out at the colposcopy clinic of Bangabandhu Sheikh Mujib Medical University (BSMMU) between January 2010 and December 2016. RESULTS: A total 16147 women attended the colposcopy clinic of BSMMU with VIA positive reports. Among them, 65.73% women were referred from different VIA centers of Dhaka district. Mean age of marriage of the subjects was 16. 93 (± 1) and mean age of 1st delivery was 18.45 years (± 4.10). Almost three-fourth of them were married before 18 years and had their 1st delivery by 20 years. Colposcopy examination of the VIA positive women revealed that 36.7% had CINI, 10.6% had CINII/ III and 7.1% had carcinoma of cervix. Considering CIN as disease the Sensitivity, Specificity, PPV and NPV of colposcopy were found 99.7%, 75.3%, 70.3% and 99.8% respectively. On other hand considering CIN2+ as disease the Sensitivity, Specificity, PPV and NPV of colposcopy were found 73.8%, 92.7%, 64.4% and 95.2% respectively. Statistical analysis revealed that higher age (p=0.000), lower level of education (p=0.007), lower socioeconomic status (p=0.014), higher parity (p=0.001) had individual influence on cervical pre-cancer and cancer. CONCLUSIONS: This study indicated higher age, low level of education, lower socio-economic condition and higher parity as most important socio-demographic factors for developing cervical pre-cancer and cancer in Bangladesh.

ABSTRACT

BACKGROUND: Cervical cancer is a major public health problem in Bangladesh. Persistence of high risk human papillomavirus (HRHPV) influences the progression of the disease, with an important role in follow- up for cervical intraepithelial neoplasia (CIN). OBJECTIVE: To establish application of high risk HPV DNA test in the follow-up of women after treatment of CIN. MATERIALS AND METHODS: This cross-sectional and hospital based study was carried out among 145 CIN treated women during the previous six months to three years at the colposcopy clinic of Bangabandhu Sheikh Mujib Medical University, Dhaka, between January 2011 and June 2012. Pap smear and HPV samples were collected and colposcopy was performed to find out the persistence of the disease. Cervical samples obtained were tested for HPV DNA using the Hybrid Capture II (HC-II) test. A cervical biopsy was collected whenever necessary. The results were compared to assess the efficacy of different methods during follow up such as Pap smear, HPV test and colposcopy. RESULTS: Mean age of the recruited women (n=145) was 33.6 (± 7.6), mean age of marriage was 16.8 (±2.9) and mean age of 1st delivery was 18.8 (±3.5) years. More than half had high grade CIN before treatment and 115 (79.3%) women were managed by LEEP and 20.7% were managed by cold coagulation. Among the 145 treated women, 139 were negative for HPV DNA and six of them (4.1%) were HPV positive. Sensitivity of Pap smear (40.0) and HPV DNA test (40.0) was poor, but specificity was quite satisfactory (>93.0) for all the tests. CONCLUSIONS: The high risk HPV DNA test can be an effective method of identifying residual disease. It can be added to colposcopy and this should be applied to all treated women attending for their first or second post-treatment follow-up visit at 6 months to one year, irrespective of the grade of treated CIN.

ABSTRACT

BACKGROUND: Visual inspection of cervix with acetic acid (VIA) is offered at 252 centers in 64 districts of Bangladesh. VIA+ve women are managed at colposcopy clinics of Bangabandhu Sheikh Mujib Medical University (BSMMU) and 14 Medical College Hospitals (MCHs). This research work has been supported by 'UICC Cancer Prevention Campaign' programme. OBJECTIVES: This study explored the role of print materials and electronic media to improve cervical cancer screening in the present socio-cultural context of Bangladesh. METHODS: This study was performed from January to August 2011 at two upazilas of Bangladesh (Singair with screening facility and Sonargaon without screening facility). Data were collected by focus group discussion (FGD) with women, husbands and community people before and after intervention. Information on cervical cancer screening and VIA camps was disseminated using advertisement through local cable line of the television, microphone announcement, service providers and leaflet throughout the week prior to a VIA camp. Three-day VIA camps were organized at the upazila health complex (UHC) of both upazilas. Quantitative data was gathered from women at the camps on source of information on VIA and the best method of awareness creation. RESULTS: The population was aware of "cancer" and a notable number knew about cervical cancer. Baseline awareness on prevention and VIA was low and it was negligible where screening services were unavailable. Awareness was increased fourfold in both upazilas after interventions and half of the women and the majority of the community people became aware of screening and available facilities. Cable line advertisement (25.5%), microphone announcement (21.4%), and discussion sessions (20.4%) were effective for awareness creation on VIA. Television was mentioned as the best method (37.4%) of awareness creation. CONCLUSION: Television should be used for nation-wide awareness creation. For local awareness creation, cable line advertisement, microphone announcements and health education at Uthan Baithaks/ EPI sessions can easily be adopted by the government.

ABSTRACT

AIM: To evaluate the feasibility of the 'see and treat' protocol for the management of high-grade cervical intraepithelial neoplasia (CIN) at a colposcopy clinic in Bangladesh. MATERIAL AND METHODS: A cross-sectional and comparative study was carried out between two periods on 358 colposcopy-diagnosed high-grade CIN at the colposcopy clinic of Bangabandhu Sheikh Mujib Medical University (BSMMU). During the first period (January 2005 to June 2008), 181 colposcopy-diagnosed high-grade CIN patients had cervical biopsy by punch biopsy forceps and histology-confirmed high-grade CIN were treated by loop electrosurgical excision procedure (LEEP). During the second period (July 2008 to December 2009), 177 colposcopy-diagnosed high-grade CIN were treated by LEEP at their first visit. RESULTS: During the first and second periods, 48 of 87 and 55 of 73 histology-proven high-grade CIN cases, respectively, received treatment. Among the study population, 37.3% women who had normal or CIN-I in histology were treated unnecessarily in the second period. The compliance of treatment improved by 20% and failure to receive treatment fell by 20%; these changes were statistically significant (P=0.006). CONCLUSION: 'See and treat' protocol is a well-accepted, feasible and useful option for management of high-grade CIN in Bangladesh. It reduces the number of visits to the clinic and failure to receive treatment.

ABSTRACT

AIM: The aim of this study was to investigate the seroprevalence of antibody to Treponema pallidum among pregnant women and its association with age, sexual behavior and socioeconomic status. MATERIALS AND METHODS: In this cross-sectional study, 1266 sera were collected from pregnant women attending Bangabandhu Sheikh Mujib Medical University and Rajshahi, Khulna and Chittagong Medical College Hospitals between February 2007 and April 2008. From each hospital, samples were collected from about a quarter of the total recruited pregnant women. Sera were tested to identify the antibody to T. pallidum using Treponema pallidum hemagglutination at the Virology Department of Bangabandhu Sheikh Mujib Medical University. Logistic regression was used to explore potential risk factors for syphilis. RESULTS: Among 1250 sera tested (16 sera were discarded due to hemolysis), 37 (2.96%) were positive for T. pallidum antibody. Higher seropositivity was associated with couples with no formal education, low socioeconomic status (P = 0.006), marriage at or before 18 years of age (P = 0.002), multiple marriages of the husband (P = 0.031) and sexual activity for more than 10 years (P = 0.007). Among these factors, low education level of women, early age of marriage and multiple marriages of the husband showed individual effects on high seropositivity to T. pallidum. CONCLUSIONS: The high seroprevalence of syphilis among pregnant women attending the antenatal clinics of these hospitals indicates the need for the incorporation of screening for syphilis in routine antenatal screening in Bangladesh. Improvement of education level in the female population, prevention of early marriage and preventing polygamy of husbands may play an important role in prevention of syphilis among women.

ABSTRACT

OBJECTIVE: To report the organization and early results of a visual inspection with acetic acid (VIA) screening program for cervical cancer prevention in Bangladesh. METHODS: Opportunistic VIA screening was offered by trained medical personnel to healthy women attending healthcare facilities in 44 districts. Colposcopy and/or directed biopsies were performed on VIA-positive women at Bangabandhu Sheikh Mujib Medical University (BSMMU) or medical college hospitals. The numbers of screened and VIA-positive women as well as the results of colposcopy, biopsy, and treatment of those with cervical intraepithelial neoplasia (CIN) attending BSMMU are reported. RESULTS: From January, 2005, to June, 2008, 104098 women underwent VIA screening. Among them, 5013 (4.8%) women were positive, of whom 4371 (87.2%) attended colposcopy clinics in different hospitals. Of the 2188 who underwent colposcopy at BSMMU, 157 were diagnosed with CIN 2-3 and 123 with invasive cancer. For 2065 women (excluding the cancer cases), results for sensitivity, specificity, and positive predictive value of VIA to detect CIN 2-3 lesions were 93.6%, 58.3%, and 15.6%, respectively. Almost half the women with CIN 2 or 3 lesions had treatment. CONCLUSION: A VIA-based program would facilitate the development of screening, diagnosis, and treatment of cervical neoplasia and improve awareness of cervical cancer prevention in Bangladesh.
