Published: December 2019

Abstrak-Minyak goreng bekas dapat digunakan sebagai bahan baku sumber energi alternatif. Minyak goreng bekas mempunyai rantai hidrokarbon panjang yang dapat dipecah untuk menghasilkan senyawa alkana dan alkena melalui proses pirolisis. Penelitian ini bertujuan untuk menghasilkan pirolisat sebagai bahan bakar alternatif berupa bio-oil dengan katalis yang telah teraktivasi larutan NaOH. Selain itu penelitian ini bertujuan untuk mengetahui kemampuan bio-oil yang dihasilkan dan dibandingkan dengan minyak tanah sebagai bahan bakar kompor. Pirolisis minyak goreng bekas telah dilakukan dengan zeolit yang diaktivasi menggunakan larutan NaOH (1, 2, 3, 4, dan 5M). Konsentrasi optimum aktivasi terjadi pada proses karakterisasi zeolit dengan uji daya serap terhadap larutan methylene blue dan uji keasaman dengan metode adsorpsi desorpsi amonia yang menghasilkan larutan NaOH 4M sebagai konsentrasi optimum. Pirolisis dilakukan dengan variasi jumlah zeolit (0, 5, 10, 15, dan 20%) terhadap minyak goreng bekas dengan parameter pengamatan pada proses pirolisis berupa data mengenai yield, lama pirolisis, dan perubahan massa katalis pergram. Hasil optimum pirolisat diperoleh pada proses pirolisis menggunakan katalis sebanyak 20%. Analisis komponen kimia penyusun pirolisat dengan GC-MS menunjukkan kandungan hidrokarbon sebesar 81,93%. Pirolisat hasil pirolisis minyak goreng bekas berpotensi sebagai bahan bakar alternatif pengganti minyak bahan bakar kompor.

A Unique “Reverse” Crescent Fragment in an Anterior-Posterior Compression Fracture
Authors: Montgomery Tyler P. , Sheppard Evan , Quade Jonathan H. 
Published: December 2019

Case:
We describe a patient with an anterior-posterior compression type pelvic fracture sustained after a motorcycle crash, with pubic symphysis disruption and a “reverse” crescent fragment. The injury force ruptured the anterior sacroiliac ligaments and travelled posterior medially, creating a complete Denis zone 2 sacral fracture, rather than rupturing the posterior sacroiliac ligaments as would be expected. The patient underwent open reduction and internal fixation of the pubic symphysis and closed reduction and percutaneous pinning of the right sacroiliac joint.

Conclusions:
This case presents a unique “reverse” crescent fragment not previously described in the literature as an anterior-posterior compression type III variant.
Irreducible Knee Dislocation Associated With a Tertiary Gastrocnemius Head
Authors: Price Ryan C. , Shultz Christopher , Richter Dustin L. , Veitch Andrew , Schenck Robert C. 
Published: December 2019

Case:
A 43-year-old man suffered an irreducible posterolateral knee dislocation while snowboarding with associated tears of the anterior cruciate, posterior cruciate, medial collateral, and posterolateral corner ligaments. Two closed reduction attempts failed, and magnetic resonance imaging revealed incarcerated soft tissue from a tertiary gastrocnemius muscle head. The patient underwent open reduction and repair/reconstruction of his multiligamentous knee injury. At the 6-year follow-up, the patient did not have pain or instability and returned to recreational activities.

Conclusions:
This case demonstrates that a tertiary gastrocnemius muscle head, the most common anatomical variation, may complicate the closed reduction of an irreducible posterolateral knee dislocation.

Published: December 2019

Background:
The identification of surgical risk factors for early anterior cruciate ligament (ACL) revision is important when appropriate treatment for patients undergoing primary ACL reconstruction is selected. The purposes of this study were to determine the short-term ACL revision rate of patients undergoing primary ACL reconstruction and to identify surgical risk factors for ACL revision within 2 years of primary ACL reconstruction.

Methods:
This study was based on data collected prospectively from the Norwegian and Swedish National Knee Ligament Registries. Patients who underwent primary ACL reconstruction from 2004 through 2014 were included. We examined revisions through 2016. The relative risks (RRs) of revision ACL reconstruction dependent on graft fixation, the time interval between injury and surgical procedure, and meniscal and cartilage injury were estimated by using generalized linear models with a binomial distribution and log-link function. The outcome was set as revision ACL reconstruction during the first 2 years.

Results:
A total of 58,692 patients were assessed for eligibility; of these, 18,425 patients were included. The overall 2-year revision rate was 2.1%. Patients treated with a metal interference screw had an increased risk of ACL revision when compared with patients who were treated with other femoral fixations (RR, 1.78 [95% confidence interval (CI), 1.38 to 2.29]; p < 0.001). The use of the RIGIDFIX Cross Pin System (DePuy Synthes) entailed a lower risk of ACL revision compared with other femoral fixations (RR, 0.58 [95% CI, 0.42 to 0.82]; p = 0.0017). Patients undergoing ACL reconstruction within 3 months of the injury had an increased risk of ACL revision (RR, 2.07 [95% CI, 1.64 to 2.61]; p < 0.001).

Conclusions:
Patients undergoing ACL reconstruction within 3 months of an injury, as well as patients treated with a metal interference screw in the femur, had a significantly higher risk of ACL revision, and patients treated with the RIGIDFIX Cross Pin in the femur had a significantly lower risk of ACL revision.

Abstract
Background Recruitment and retention in clinical trials remains an important challenge, particularly in the context of advanced disease. It is important to understand what affects retention to improve trial quality, minimise attrition and reduce missing data. We conducted a qualitative study embedded within a randomised feasibility trial and explored what influenced people to take part and remain in the trial. Methods Qualitative study embedded within a double blind randomised trial (BETTER-B(Feasibility): BETter TreatmEnts for Refractory Breathlessness) designed using a person-centred approach. Participants with cancer, Chronic Obstructive Pulmonary Disease (COPD), Interstitial Lung Disease (ILD), or Chronic Heart Failure (CHF), with a Modified Medical Research Council Dyspnoea Scale grade 3/4 were recruited from three UK sites. A convenience subsample completed qualitative interviews after the trial. Interviews were analysed using thematic analysis. Results were considered in relation to the core elements of person-centred care and our model of the person-centred trial. Results In the feasibility trial 409 people were screened for eligibility and 64 randomised. No participant was lost to follow up. 22 participants took part in a qualitative interview. 11 had a diagnosis of COPD, 8 ILD, 2 CHF, and 1 lung cancer. Median age was 71 years (56-84). 16 were male. 20 had completed the trial, 2 withdrew due to adverse effects. The relationship between patient and professional, potential for benefit, trial processes and the intervention all influenced the decision to participate in the trial. The relationship with the research team and continuity, perceived benefit, and aspects relating to trial processes and the intervention influenced the decision to remain in the trial. Conclusions In this feasibility trial recruitment targets were met, attrition levels were low, and aspects of the person-centred approach were viewed positively by trial participants. Prioritisation of the relationship between the patient and professional; person centred processes including home visits, assistance with questionnaires, and involvement of the carer; and enabling people to participate by having processes in line with individual capabilities appears to support recruitment and retention in clinical trials in advanced disease. We would recommend the integration of a person-centred approach in all clinical trials.

Abstract
Background: HIV testing is a gateway to HIV care and treatment for those testing positive and can link those with negative results to HIV preventive services. Despite the importance of HIV testing services (HTS) in HIV control, uptake of HTS among female sex workers (FSWs) across sub-Saharan Africa (SSA) remains sub optimal. Concerns about stigma associated with sex work and fear of loss of livelihood if HIV status becomes known, are some of the restrictions for FSWs to utilize HTS offered through health care facilities. Introduction of HIV self-testing (HIVST) may mitigate some of the barriers for the uptake of HTS. This study explored perspectives of FSWs towards HIVST in Tanzania. Methods: We conducted an exploratory study employing in-depth interviews (IDI) and participatory group discussions (PGD) with FSWs in selected regions of Tanzania. Study participants were recruited through snowball sampling. Data were thematically analysed by two analysts using NVivo software. Emerging themes were explored in the tradition of Grounded Theory. The analysis was informed by the social ecological model and focused on factors associated with the feasibility of scaling up HIVST. Results: A total of 23 PGD sessions were conducted involving 227 FSWs. Data from PGDs were complemented by 21 IDI. FSWs were enthusiastic toward HIVST. Convenience (time and cost saved), and belief that HIVST will increase privacy and confidentiality motivated participants’ support for the self-testing approach. Participants did express concerns about their ability to interpret and trust the results of the test. Participants also expressed concern that HIVST could cause personal harm, including severe distress and self-harm for individuals with reactive test. This was linked to the study participants’ perception that HIVST would be provided only through unassisted modality. Conclusions: FSWs demonstrated high enthusiasm to use the HIVST once it becomes available. Increased confidentiality, reduced opportunity costs, and increased autonomy were among the key factors for the intended use of HIVST. Major concerns included fear of HIV reactive test and not trusting self-diagnoses. Our findings underscore the importance of providing adequate access to counselling and referral services in conjunction with HIVST.

Abstract
Objectives To examine the effectiveness and safety of yoga for women with sleep problems by performing a systematic review and meta-analysis.Methods Medline/PubMed, Clincalkey, ScienceDirect, Embase, PsycINFO, and the Cochrane Library were searched throughout the month of June 2019. Randomized controlled trials comparing yoga groups with control groups in women with sleep problems were included. Two reviewers independently evaluated risk of bias by using the risk of bias tool suggested by the Cochrane Collaboration for programming and conducting systematic reviews and meta-analyses. The main outcome measure was sleep quality or the severity of insomnia, which was measured using subjective instruments, such as the Pittsburgh Sleep Quality Index (PSQI), Insomnia severity index (ISI), or objective instruments, such as polysomnography, actigraphy, and safety of the intervention. For each outcome, standardized mean difference (SMD) and 95% confidence intervals (CIs) were determined. Results Nineteen studies including 1832 participants were included in this systematic review. Meta-analyses revealed positive effects of yoga using PSQI or ISI scores in 16 randomized control trials (RCTs) compared with the control group in improving sleep quality in women, PSQI (SMD = −0.54; 95% CI = −0.89 to −0.19 ; P = 0.003). However, three RCTs revealed no effects of yoga compared with the control group in reducing the severity of insomnia in women using ISI (SMD = −0.13; 95% CI = −0.74 to 0.48; P = 0.69). Seven RCTs revealed no evidence for effects of yoga compared with the control group in improving sleep quality for women with breast cancer using PSQI (SMD = −0.15 ; 95% CI = −0.31 to 0.01; P = 0.5). Four RCTs revealed no evidence for the effects of yoga compared with the control group in improving the sleep quality for peri-or postmenopausal women using PSQI (SMD = −0.31; 95% CI = −0.95 to 0.33; P = 0.34).Yoga was not associated with serious adverse events. Discussion This systematic review and meta-analysis found that yoga intervention in some groups of women was beneficial in managing sleep problems. Despite certain disadvantages in methodology in the included studies, yoga may be recommended as a complementary therapy to women.
Mental health among immigrants in Germany – the impact of self-attribution and attribution by others as an immigrant

Published: December 2019

Abstract
Background: In Germany, the term ‘migration background' has been established to differentiate between immigrants and natives. In the present study post-traumatic stress disorder (PTSD), anxiety, and depression were analysed in immigrant populations in Germany by considering self-attribution as well as attribution by others on one’s own ‘migration background’.

Methods: In a population-based survey (N = 2317), socio-demographic characteristics, migration background (official statistics definition vs. self-attribution as well as the anticipated attribution by others), PTSD (PCL-5), and symptoms of anxiety and depression (PHQ-4) were assessed. Logistic regression models were applied to predict mental health outcomes by considering socio-demographic and immigration-related factors.

Results: A total of 10.7% of respondents (N = 248) had a ‘migration background’. Immigrants of the 2nd generation compared to 1st generation immigrants are less likely to see themselves as immigrants. Attribution as an immigrant (self and/or by others) was found as significant predictor for PTSD and depression, but not anxiety.

Conclusions: It seems useful to focus on immigration-related factors considering subjective perspectives and not only comparing immigrants and natives using a federal statistics definition. Our findings suggest that research on the association between immigration-related factors such as attribution as an immigrant and mental health outcomes might be a promising approach to better identify subgroups at higher risk of mental distress.
Short and Long-term Barriers and Facilitators of Skin Self-Examination Among Individuals Diagnosed with Melanoma
Authors: Coroiu Adina , Moran Chelsea , Bergeron Catherine , Drapeau Martin , Wang Beatrice , Kezouh Abbas , Ernst Jochen , Batist Gerald , Körner Annett 
Published: December 2019

Abstract
Background
Melanoma can be lethal if not detected early and treated. Early detection can be facilitated via skin self-examination (SSE) and as such, SSE is part of melanoma follow-up care for individuals with a prior history, who face a life-long risk of reoccurrence. The objective of the current study was to identify short- and long-term predictors of SSE among melanoma survivors to inform future prevention interventions in high-risk groups.
Method
This is an observational study with longitudinal assessments conducted with adult melanoma patients in active follow-up care.
Primary Outcome Measures: Behavioral outcomes, comprehensive SSE (checking up to 5 body areas in the last 3 months) and optimal SSE (checking the entire body at least monthly in the last 3 months) were assessed at 3, 12, and 24 months post a dermatological educational session on skin cancer prevention. T tests and chi square analyses were used to examine changes in outcomes from 3 to 12 and 24 months. Linear and logistic regression models were used to examine the association between predictors and the primary outcomes.
Results
Comprehensive SSE did not decrease significantly from 3 (M=2.7, SD=1.1) to 12 (M=2.6, SD=1.2) and 24 months (M=2.4, SD=1.2) post the education session, with the stronger predictor at all timepoints being intentions to perform SSE. Optimal SSE was higher at 3 months (59%) compared to 12 (46%) and 24 months (34%), with key predictors including self-efficacy and intentions to perform SSE and male sex at 3 months post; self-efficacy and reliance on medical advice at 12 months; and (lower) education and self-efficacy at 24 months.
Conclusions
The key findings of this study are that 1) survivors maintain SSE behaviour over time, but rates of SSE performed in agreement with medical recommendations are higher immediately post standard dermatological education (i.e. usual care) and decrease somewhat over a 24-month period; and 2) the strongest psycho-social predictors of SSE are intentions and self-efficacy to perform the behavior, which are highly modifiable, for example via motivational interviewing and goal setting health interventions.

Published: December 2019

Abstract
Background: Victimisation of women is encountered in all countries across the world, it damages the mental and physical health of women. During pregnancy and the postpartum period, women are at a greater risk of experiencing violence from an intimate partner. The aim of this study was to explore childbirth outcomes in a Swedish population of women reporting a history of violence including domestic violence during pregnancy.

Methods: A longitudinal cohort design was used. In total, 1939 pregnant women ≥ 18 years were recruited to answer two questionnaires, both questionnaires were administered in the early and late stages of their pregnancy. The available dataset included birth records of 1694 mothers who gave birth between June 2012 and April 2014. Statistical analyses included descriptive statistics, T-test and bivariate logistic regression. Results: Of 1694 mothers 38.7 % (n = 656) reported a history of violence and 2% (n = 34) also experienced domestic violence during pregnancy. Women who were single, living apart from their partner, unemployed, smoked and faced financial distress were at a higher risk of experiencing violence (p = 0.001). They also had significant low scores on the SOC-scale and high EDS-scores ≥ 13 (p =0.001) when compared to women without a history of violence (p = 0.001). Having a history of violence increased the woman’s risk of undergoing a caesarean section (OR 1.33, 95 % CI 1.02 -1.70). A history of emotional abuse also significantly increased the risk of having a caesarean section irrespective of whether it was a planned or an emergency caesarean section (OR 1.50, 95% CI 1.09-2.06). Infants born to a mother who reported a history of violence, were at significant risk of being born premature < 37 weeks of gestation compared to infants born by mothers with no history of violence (p = 0,049). Conclusions: A history of violence and/or exclusively a history of emotional abuse has a negative impact on childbirth outcomes including caesarean section and premature birth. Therefore, early identification of a history of or ongoing violence is crucial to provide women with extra support which may have positive impact on her birth outcomes.
Profiling novel alternative splicing within multiple tissues puts insight into the porcine genome annotation
Authors: Feng Wen , Zhao Pengju , Zheng Xianrui , Liu Jian-Feng 
Published: December 2019

Abstract
Background
Alternative splicing (AS) is a process that mRNA precursor splices intron to form the mature mRNA. AS plays important roles in contributing to transcriptome and proteome divert. However, to date there is no research about pig AS in genome-wide level by RNA sequencing.
Results
To characterize the AS in pigs, herein we detected genome-wide transcripts and events by RNA sequencing technology (RNA-seq) 34 different tissues in Duroc pigs. In total, we identified 138, 403 AS events and 29, 270 expressed genes. We found alternative donor site was the most common AS form, which is accounted for 44% of the total AS events. The percentage of the other 3 AS forms (Exon skipping, Alternative acceptor site and Intron retention) are all around 19%. The results showed that the most common AS events (alternative donor site) can produce different transcripts or different proteins which affect the biological process. Among these AS events, 109, 483 were novel AS events, and the number of alternative donor splice site has increased the most (Accounting for 44% of the novel AS events).
Conclusions
The expression of gene with tissue specific AS events showed that the functions of these genes were consistent with the tissue function. AS increased proteome diversity and resulted in novel proteins that gained and lost important functional domains. In summary, these findings extend genome annotation and highlight roles that AS acts in tissue identity in pig.
