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
Recent years have seen a sustained interest in the development of circadian reentrainment strategies to limit the deleterious effects of jet lag. Due to the dynamical complexity of many circadian models, phase-based model reduction techniques are often an imperative first step in the analysis. However, amplitude coordinates that capture lingering effects (i.e., memory) from past inputs are often neglected. In this work, we focus on these amplitude coordinates using an operational phase and an isostable coordinate framework in the context of the development of jet-lag amelioration strategies. By accounting for the influence of circadian memory, we identify a latent phase shift that can prime one's circadian cycle to reentrain more rapidly to an expected time-zone shift. A subsequent optimal control problem is proposed that balances the trade-off between control effort and the resulting latent phase shift. Data-driven model identification techniques for the inference of necessary reduced order, phase-amplitude-based models are considered in situations where the underlying model equations are unknown, and numerical results are illustrated in both a simple planar model and in a coupled population of circadian oscillators.

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
In this study, mechanical properties of friction stir welded Aluminum Alloy (AA) 6061 in three different heat treatment conditions i.e. Annealed (O), Artificially aged (T6) and Post Weld Heat Treated (PWHT) were compared. Plates were welded in a butt joint form. Parameters were optimized and joints were fabricated using tool rotational speed and travel speed of 500 rpm and 350 mm/min respectively. Two sets of plates were welded in O condition and out of which one was, later, subjected to post weld artificial aging treatment. Third set was welded in T6 condition. The welds were characterized by macro and microstructure analysis, microhardness measurement and mechanical testing. SEM fractography of the tensile fracture surfaces was also performed. Comparatively better mechanical properties were achieved in the plate with PWHT condition.

Abstract
In this study optimization of maximum travel speed that can be achieved for Friction Stir Welding of Aluminum Alloy 2014-T6 without compromising the mechanical properties was carried out. Joints were made at different travel speeds of 200, 300, 400, 500 and 600 mm/min with constant tool rotational speed of 800 rpm and tool tilt angle of 2.The samples were characterized by stereo microscopy, optical microscopy, scanning electron microscopy, Vickers microhardness testing and tensile testing. Microstructural features of as-welded samples revealed refined equiaxed grains in nugget zone and grain growth in the heat effected zone. Tensile test results showed that the tensile strength was maximum at travel speed of 500 mm/min but then decreased after further increasing the travel speed. Hardness in the nugget zones of all welds was lower than that of base material. Fractographic analysis exhibited significant variations in fracture surfaces of tensile samples. A relationship between the welding parameters and resultant heat inputs was also discussed.

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
Extracorporeal membrane oxygenation (ECMO) is considered a salvage therapy in patients with acute respiratory distress syndrome (ARDS) and refractory hypoxemia (hypoxemia persisting despite lung-protective ventilation). One aspect of ECMO is whether there would be an application of the technology related to the Coronavirus pandemic. The number of people diagnosed with Coronavirus disease (COVID19) has crossed the five million mark on 9 August 2020, with a case fatality rate of 5.2%. Due to this exponential increase in the number of coronavirus disease (COVID19) cases particularly the ones associated with ARDS, experts are evaluating the need for ECMO in intensive care units. Herein, we chronicle a review encompassing the available evidence on ECMO and its potential role in COVID19 ARDS, as we aim for optimal patient care with appropriate resource utilization and conservation.

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.
