Abstract
Worldwide Hepatitis B is known as one of the imperative causes of mortality and morbidity as well as occupational health hazard among health workers. Bangladesh is intermediate endemic country for Hepatitis B infection for which the government has introduced hepatitis B vaccination into the Expanded Programme on Immunization (EPI) nationwide since 2009 for new born children. However, the people who were born before 2009, was dependent on imported hepatitis B vaccine as there was no locally manufactured hepatitis B vaccine in Bangladesh. Hence, we conducted a randomized observer blinded non-inferiority clinical trial to assess the immunogenicity and safety of the locally manufactured Hepa-B vaccine in comparison with World Health Organization prequalified Engerix-B vaccine. Total 158 eligible adult participants were enrolled in this study with mean age of 30 and 29 years old in Hepa-B and Engerix-B groups, respectively. Both the vaccines were administered intramuscularly at 0, 1 and 6 months schedule. Baseline and post vaccination anti-HBs titers were measure at different time points. Seroconversion rate post three doses of Hepa-B vaccine was 98.67% similar to the comparator Engerix-B vaccine which was 100%. The geometric mean test ratios of both vaccines at all analysis time points were found > 0.5 predefined non-inferiority margin. Soreness at the injection site was the most common symptom for both the vaccines which resolved without any complication. No serious adverse event was reported throughout the study period. These results suggest that locally manufactured hepatitis B vaccine 'Hepa-B' vaccine is non-inferior to the well-known licensed 'Engerix-B' vaccine. ClinicalTrials.gov NCT03627507.

Abstract
OBJECTIVES The present investigation examined the role of factors involved in suicide ideation and suicide attempt using a nationally representative sample of US high school students. METHODS Data were collected from students in Grades 9-12 as part of the Youth Behavioral Survey (n = 11,328). Logistic regression models were used to examine factors associated with suicide ideation and suicide attempt. Variables included demographic characteristics (grade, sex, and race), psychosocial factors (physical fighting, sexual violence, sports participation, bullying, and electronic bullying), and substance use (cigarette usage, marijuana usage, and alcohol usage). RESULTS The factor most associated with suicide ideation was bullying (either electronic or physical), whereas the factor most associated with suicide attempt was sexual violence followed closely by physical bullying. CONCLUSIONS The multitude of instigators and commonality among gender, ethnicity, and socio-economic status give an indication of how to prevent suicide and who to target information regarding the hazards of suicide.

Abstract
BACKGROUND Identifying patients with sentinel node (SN)-negative melanoma who are at greatest risk of recurrence is important. The European Organization for Research and Treatment of Cancer (EORTC) Melanoma Group proposed a prognostic model that has not been validated in population-based data. The EORTC nomogram includes Breslow thickness, ulceration status and anatomical location as parameters. The aim of this study was to validate the EORTC model externally using a large national data set. METHODS Adults with histologically proven, invasive cutaneous melanoma with a negative SN biopsy in the Netherlands between 2000 and 2014 were identified from the Dutch Pathology Registry, and relevant data were extracted. The EORTC nomogram was used to predict recurrence-free survival. The predictive performance of the nomogram was assessed by discrimination (C-statistic) and calibration. RESULTS A total of 8795 patients met the eligibility criteria, of whom 14·7 per cent subsequently developed metastatic disease. Of these recurrences, 20·9 per cent occurred after the first 5 years of follow-up. Validation of the EORTC nomogram showed a C-statistic of 0·70 (95 per cent c.i. 0·68 to 0·71) for recurrence-free survival, with excellent calibration (R2 = 0·99; P = 0·999, Hosmer-Lemeshow test). CONCLUSION This population-based validation confirmed the value of the EORTC nomogram in predicting recurrence-free survival in patients with SN-negative melanoma. The EORTC nomogram could be used in clinical practice for personalizing follow-up and selecting high-risk patients for trials of adjuvant systemic therapy.

Abstract
BACKGROUND A nomogram to predict sentinel node (SN) positivity [the Melanoma Institute Australia (MIA) nomogram] was recently developed and externally validated using two large single-institution databases. However, there remains a need to further validate the nomogram's performance using population-based data. OBJECTIVES To perform further validation of the nomogram using a European national patient cohort. METHODS Patients with cutaneous melanoma who underwent SN biopsy in the Netherlands between 2000 and 2014 were included. Their data were obtained from the Dutch Pathology Registry. The predictive performance of the nomogram was assessed by discrimination (C-statistic) and calibration. Negative predictive values (NPVs) were calculated at various predicted probability cutoffs. RESULTS Of the 3049 patients who met the eligibility criteria, 23% (691) were SN positive. Validation of the MIA nomogram (including the parameters Breslow thickness, ulceration, age, melanoma subtype and lymphovascular invasion) showed a good C-statistic of 0·69 (95% confidence interval 0·66-0·71) with excellent calibration (R2 = 0·985, P = 0·40). The NPV of 90·1%, found at a 10% predicted probability cutoff for having a positive SN biopsy, implied that by using the nomogram, a 16·3% reduction in the rate of performing an SN biopsy could be achieved with an error rate of 1·6%. Validation of the MIA nomogram considering mitotic rate as present or absent showed a C-statistic of 0·70 (95% confidence interval 0·68-0·74). CONCLUSIONS This population-based validation study in European patients with melanoma confirmed the value of the MIA nomogram in predicting SN positivity. Its use will spare low-risk patients the inconvenience, cost and potential risks of SN biopsy while ensuring that high-risk patients are still identified.

Abstract
Cabbage (Brassica oleracea) is popular winter vegetables cultivated all over Bangladesh
and contains essential nutrients. This study aimed to evaluate the efficacy of pre-blanching
on the preservation of cabbage by drying. In this research work, cabbage was blanched at
80°C, 90°C, and 100°C temperature for 12, 8, and 2 mins, respectively. Then the samples
were dried at 60°C maintaining 60% relative humidity. The moisture and ash content of
untreated and treated dried samples was in the range of 16.07±0.04 to 10.80±0.01% and
5.71±0.06 to 3.81±0.02%, respectively. The total phenolic content in cabbage was
74.47±0.63 mg GAE/100g at 100°C blanching temperature for a short time of 2 mins,
which was higher compared to 61.91±0.48 mg GAE/100g at 80°C for 12 mins. It was
observed that the antioxidant activity and two water-soluble vitamins-ascorbic acid and
beta carotene decreased in pre-blanched dried samples in contrast with fresh ones.
Blanching at higher water temperature and a short period was found useful for the
retention of total phenolic content and greenness of cabbage. Blanching pre-treatments
were also found to have better color retention capacity than untreated dried cabbage. A
proper combination of drying time and temperature, along with the incorporation of
blanching pretreatment, might be useful to preserve cabbage for a long time.

Abstract
Cosmetic products are often inadequately preserved that provide favourable environment for microbial growth. These emphasize the need for regular investigation of cosmetics in terms of microbial quality and preservative capacity. This study aimed to evaluate the microbial quality, in vitro antibacterial activity and preservative capacity of several popular cosmetics collected from the neighbouring health-care stationary shops in Dhaka city from October 2019 to December 2019. Here, a total of five categories of seven different cosmetic products were subjected to evaluate microbial load, in vitro antibacterial activity and preservative capacity. Among the seven cosmetic products, the viable bacterial count in two cosmetics (All Clear and Sunsilk Shampoo) were found within the acceptable range that was <10³ CFU/ml. None of the cosmetics were found contaminated with fungus and pathogenic organisms. Conversely, three (one Mouthwash and two shampoo) products showed in vitro antibacterial activity against E. coli, S. aureus, Pseudomonas spp., Salmonella spp., Shigella spp. Only single cosmetic product (Cute coconut oil) did not meet the criteria of preservative capacity, while rest six products fulfil the requirements. Thus, our findings revealed a huge load of microorganisms in spite of having adequate preservative capacity in most of the tested products.

Abstract
BACKGROUND It has been claimed, without supporting evidence, that knowledge of sentinel node (SN) status does not provide more accurate prognostic information than basic clinicopathological features of a primary cutaneous melanoma. We sought to investigate this claim and to quantify any additional value of SN status in predicting survival outcome. PATIENTS AND METHODS Data for a Dutch population-based cohort of melanoma patients (n = 9272) and for a validation cohort from a large Australian melanoma treatment center (n = 5644) were analyzed. Patients were adults diagnosed between 2004 and 2014 with histologically-proven, primary invasive cutaneous melanoma who underwent SN biopsy. Multivariable Cox proportional hazards analyses were carried out in the Dutch cohort to assess recurrence-free survival (RFS), melanoma-specific survival (MSS) and overall survival (OS). The findings were validated using the Australian cohort. Discrimination (Harrell's C-statistic), net benefit using decision curve analysis and net reclassification index (NRI) were calculated. RESULTS The Dutch cohort showed an improved C-statistic from 0.74 to 0.78 for OS and from 0.74 to 0.76 for RFS when SN status was included in the model with Breslow thickness, sex, age, site, mitoses, ulceration, regression and melanoma subtype. In the Australian cohort, the C-statistic increased from 0.70 to 0.73 for OS, 0.70 to 0.74 for RFS and 0.72 to 0.76 for MSS. Decision curve analyses showed that the 3-year and 5-year risk of death or recurrence were more accurately classified with a model that included SN status. At 3 years, sensitivity increased by 12% for both OS and RFS in the development cohort, and by 10% and 6% for OS and RFS, respectively, in the validation cohort. CONCLUSIONS Knowledge of SN status significantly improved the predictive accuracy for RFS, MSS and OS when added to a comprehensive suite of established clinicopathological prognostic factors. However, clinicians and patients must consider the magnitude of the improvement when weighing up the advantages and disadvantages of SN biopsy for melanoma.

Abstract
Introduction Proximal femoral nail (PFN) is a commonly used implant for intertrochanteric fractures which is designed according to western femoral measurements. However, anthropometry of proximal femur in Indian and in general, Asian, are smaller. So a modified short PFN with smaller dimensions was developed. This study analyses the radiological and functional outcome of treatment of intertrochanteric fractures with modified short PFN. Materials and Methods A retrospective study analysed 120 adult patients operated between 2014-2017 using modified short PFN for intertrochanteric fractures, having a minimum follow-up of 12 months. Clinical and radiological parameters including tip-apex distance (TAD), position of tip of lag screw in femoral head, lateral slide of lag screw as well as length of anti-rotation screw were measured. Final functional outcome was assessed using Barthel's index and Kyle's criteria. Results Good reduction was achieved in 90.83% cases and 79.16% had ideal placement of lag screw in femoral head. Intra-operative difficulties were encountered in 13.33% (n=16). Mean TAD AP (anteroposterior) was 11.8mm, TAD LAT (lateral) was 11.0mm and mean TAD TOT was 22.8mm. Overall mean lateral slide was 3.20mm and it was more in unstable fracture. We had five mechanical failures, one patient with screw breakage without loss of reduction and two peri-implant fractures after union. 81.66% returned to pre-injury levels of activity with 88.33% good to excellent outcome as per Kyle's criteria. Conclusion Although, not devoid of complications, modified short PFN results in good functional recovery of patients with intertrochanteric fractures of femur.

Abstract
The study was carried out to investigate the microbiological quality of dried foods which
are very popular among kids. Moreover, people from all age groups like it, although adults
do not take it on a regular basis, the total consumed amount among the adults are not
negligible. Chips, biscuits, muesli, salted peanuts all are dried foods, and all of these can
undergo microbial contamination due to the remaining water activity, environmental
condition, production processing faults, humidity, temperature etc. In the current study,
twenty-four samples were analyzed for microbial quality analysis. Six samples from each
category of dried food were subjected to study for the presence of mesophilic organisms,
coliforms, molds and other specific food pathogens. Of the samples studied, almost all
were found to be contaminated with the mesophilic bacteria (104
-107CFU/g) and fungus
(105
-107CFU/g). Survival of Vibrio spp. was absent and Salmonella spp. was found in
only one sample. Escherichia coli, Pseudomonas spp., Staphylococcus spp. and Shigella
spp. were found in many of the samples indicating the poor quality of the dried food items.
Overall, the present study revealed that potato chips were highly contaminated by bacteria
and fungi. Consuming such contaminated chips may cause foodborne illness that is a great
threat to our health.

Abstract
Malnutrition continues to affect the growth and development of millions of children worldwide, and chronic undernutrition has proven to be largely refractory to interventions. Improved understanding of metabolic development in infancy and how it differs in growth-constrained children may provide insights to inform more timely, targeted, and effective interventions. Here, the metabolome of healthy infants was compared to that of growth-constrained infants from three continents over the first 2 years of life to identify metabolic signatures of aging. Predictive models demonstrated that growth-constrained children lag in their metabolic maturity relative to their healthier peers and that metabolic maturity can predict growth 6 months into the future. Our results provide a metabolic framework from which future nutritional programs may be more precisely constructed and evaluated.

Abstract
After the large influx of Rohingya nationals (termed Forcibly Displaced Myanmar National; FDMN) from Rakhine State of Myanmar to Cox’s Bazar in Bangladesh, it was apparent that outbreaks of cholera was very likely in this setting where people were living under adverse water and sanitation conditions. Large campaigns of oral cholera vaccine (OCV) were carried out as a preemptive measure to control cholera epidemics. The aim of the study was to evaluate the immune responses of healthy adults and children after administration of two doses of OCV at 14 days interval in FDMN population and compare with the response observed in Bangladeshi’s vaccinated earlier. A cross-sectional immunogenicity study was conducted among FDMNs of three age cohort; in adults (18+years; n = 83), in older children (6–17 years; n = 63) and in younger children (1–5 years; n = 80). Capillary blood was collected at three time points to measure vibriocidal antibodies using either plasma or dried blood spot (DBS) specimens. There was a significant increase of responder frequency of vibriocidal antibody titer at day 14 in all groups for Vibrio cholerae O1 (Ogawa/Inaba: adults-64%/64%, older children-70%/89% and younger children-51%/75%). There was no overall difference of vibriocidal antibody titer between FDMN and Bangladeshi population at baseline (p = 0.07–0.08) and at day 14, day 28 in all age groups for both serotypes. The seroconversion rate and geometric mean titer (GMT) of either serotype were comparable using both plasma and DBS specimens. These results showed that OCV is capable of inducing robust immune responses in adults and children among the FDMN population which is comparable to that seen in Bangladeshi participants in different age groups or that reported from other cholera endemic countries. Our results also suggest that the displaced population were exposed to V. cholerae prior to seeking shelter in Bangladesh. Oral cholera vaccines (OCV) are now on the WHO stockpile and targeted for use for countries with outbreaks and epidemics but also for control of endemic cholera. In Bangladesh many studies have been carried out to assess the safety, immunogenicity as well as feasibility of vaccination in the endemic settings of the country. However, with the large recent influx of displaced Rohingya nationals from Myanmar (termed Forcibly Displace Myanmar National; FDMN), mass campaigns with OCV were conducted between October 2017-December 2018. However, no data is available of the previous exposure to cholera of this population, prior to their arrival in Bangladesh. An assessment of immunogenicity status of FDMN is needed to find out if OCV is able to elicit comparable immune response and whether the same dose regimen of OCV was immunogenic among the FDMNs. In this study, we have measured the immune responses to the OCV, Shanchol, in adults (18 years and above), older children (6–17 years), and younger children (1–5 years). The results of this study shows that the oral cholera vaccine capable of inducing an immune response in adults and children among this FDMN population and the responses were comparable to that seen in Bangladeshi participants in earlier studies.

Abstract
We have earlier reported that a single dose of oral cholera vaccine (OCV) is protective in adults and children ≥5 years of age and sustained for 2 years. We enrolled participants (n = 240) from this study, between March-September 2017, over 3 years after receiving a primary single dose. Immune responses were measured in placebo group (Primary Immunization group: PI) and compared with those who received a single dose (Booster Immunization group: BI). The children were 4 to <5 years, 5 to <18 years and adults >18 years. Blood was collected at day 0 (before vaccination) and after receiving 1st and 2nd doses of OCV. Overall, the BI and PI groups showed vibriocidal antibody response after 1st and 2nd dose of vaccination in all age groups to V. cholerae O1 and O139. Young children in the BI group showed significantly higher vibriocidal antibody response two weeks after receiving the first dose as compared to PI group to LPS. Elevated plasma IgA responses to LPS after the first dose were observed among the BI group compared to the PI group among the young children. Mucosal antibody responses measured in fecal extracts showed similar increases as that of vibriocidal and LPS responses in the BI group. These results suggest a single boosting dose of OCV generated immune response in primed population >5 years of age who had earlier received OCV. However, young children who had received OCV earlier, boosting after a single dose, resulted in increased immune responses compared to the PI group. Further studies are needed to assess protection obtained from different strategies, especially for young children and to determine the numbers of primary and booster doses needed. In addition, more information is needed regarding the optimum interval between primary and booster doses to plan future interventions for cholera control. ClinicalTrials.gov Identifier: NCT02027207.

Abstract
Abstract
Background
Apart from few small single-center studies there are limited data about STEMI patients in Egypt.
Patients and methods
The European Society of Cardiology (ESC) Registry on ST Elevation Myocardial Infarction is a prospective, multicenter and observational registry. Nineteen Egyptian centers (with and without PCI facilities) participated in this registry with 1356 patients who were compared to 7420 patients from other ESC countries. Patient recruitment started from March 2016 to February 2018.
Aims of the study
The aims of this study was to describe the characteristics of patients with STEMI, to assess STEMI management patterns, to evaluate in-hospital patient outcome and to compare Egyptian patients with other ESC countries.
Results
Compared to other ESC countries, Egyptian patients were younger (mean age 55.4±11.3 vs. 62.9±12.4; P<0.001 and 4.3% vs. 19.4%% were ≥75 years old; P<0.001) with fewer females (18.4% vs. 25.6%; P<0.001). Fewer Egyptian patients had history of myocardial infarction (7.9% vs. 12.6%; P<0.001), chronic heart failure (2.0% vs. 11.5%; P<0.001), but Egyptians had higher prevalence of current smoking (59.0% vs. 42.8% p<0.001), Diabetes mellitus (40.7% vs. 21.9%, p<0.001). Egypt had longer median time between symptoms onset and first medical contact: 120.0 (60.0; 240.0) vs. 100.0 (50.0; 240.0) p<0.001. Self-presentation rather than EMS presentation was the mode of admission in 86.0% in Egypt vs. 25.8% in EU countries (p<0.001). On qualifying ECG, anterior STEMI was in 57.0% in Egypt vs. 45.9% in other countries (p<0.001). Initial reperfusion therapy was 49.1%, 43.0% and 7.2% for Primary PCI, thrombolytic therapy and no reperfusion in Egypt vs. 85.4%, 7.2% and 7.8% for EU countries, respectively. Thrombolysis when given was in the CCU/ICU rather than EMS or ER in 97.2% in Egypt vs. 43.7% in other countries. Compared to thrombolytic therapy, patients who were treated with primary PCI had less Cerebrovascular accident (0.75% vs. 1.3%; P<0.001), killip Class IV (3.0% vs. 5.9%; P<0.001) or AF (2.5% vs. 3.6%; P 0.008). In hospital mortality was 4.6% in Egypt vs. 3.5% in other countries P 0.040 and was 18.7% in No reperfusion vs. 2.1% in Primary PCI vs. 4.9% in Thrombolysis (P<0.001) among Egyptians. Patients were discharged on Aspirin in 98.6%, Clopidogrel in 91.0%, Ticagrelor in 7.1%, DAPT in 97.6%, Beta Blockers in 82.8%, ACE inhibitors in 84.7%, MRAs in 10.0%, and Statins in 99.7%.
Conclusion
Egyptian STEMI patients were younger, more frequently obese, smokers and diabetics had significantly longer delay between symptoms onset and first medical contact with more self-presentation rather than the recommended EMS presentation. Primary PCI was offered to only half of the patients. In hospital mortality was significantly higher and was highest among non-reperfused patients. National plans for primary and secondary prevention are urgently needed in Egypt.
